  • Liposomes or traditional adjuvants: induction of bactericidal activity by
           the macrophage infectivity potentiator protein (Mip) of Neisseria
           meningitidis
    • Authors: Liliana Costoya; Juan Marzoa, Carlos Ferreirós, Maria Teresa Criado
      Abstract: Currently, one of the main approaches to achieve a vaccine for serogroup B Neisseria meningitidis is based on outer membrane proteins with low antigenic variability among strains. Since these proteins tend to be minor components of the outer membrane, recombinant production is required to obtain them in sufficient amounts for evaluation and development of vaccines. In this study, we analysed the ability of recombinant macrophage infectivity potentiator (rMip) protein to induce protective bactericidal activity in mice. The rMip protein was cloned from N. meningitidis strain H44/76 and was used to immunise mice, and the sera obtained were tested against the homologous and several heterologous N. meningitidis strains. The sera were obtained using the rMip alone, with adjuvant Al(OH)3, or after inclusion into liposomes. Bactericidal activity was variable depending on the strain, although high titres were seen against strains H44/76 and NmP27. Liposomes enhanced fourfold the reactivity against the homologous strain. The results presented suggest that the rMip protein should be considered a promising candidate for the improvement of future protein-based vaccines.

  • A unique case of bilateral ovarian splenosis and review of the literature
    • Authors: Maria Giulia Disanto; Francesca Mercalli, Andrea Palicelli, Alberto Arnulfo, Renzo Boldorini
      Abstract: Splenosis is an acquired anomaly related to heterotopic auto-transplantation of splenic tissue following abdominal trauma or splenectomy. We report the first definitive bilateral ovarian case in a 65-year-old woman who underwent splenectomy following a motor vehicle accident 44 years prior to presentation. We review the literature and discuss the main differential diagnoses. Gross examination revealed a 1-cm well-circumscribed dark nodule on the surface of each ovary. Paraffin-embedded, formalin-fixed blocks were sectioned and stained with hematoxylin–eosin and immunostains (CK5/6, Calretinin, WT1, Vimentin). The histological presence of both red and white splenic pulp, delimitation from ovarian tissue and ovarian origin of blood supply, as well as medical history, led us to the correct diagnosis. The outer nodular surface was covered by mesothelium (WT1+, CK5/6+, Calretinin+, Vimentin+), which was in continuity with the ovarian surface epithelium. To our knowledge, only six previous cases of ovarian splenosis are reported. Our patient is the oldest, with a very long interval from splenectomy to presentation. Clinically, splenosis may mimic malignancy, and a correct diagnosis avoids unnecessary overtreatment. The differential diagnosis includes an accessory spleen, spleno-gonadal fusion, and splenic hamartoma: they should be excluded to come to the correct diagnosis.

  • NUT carcinoma presenting in the palate – a case report
    • Authors: Libana Raffoul Bjornstrup; Jesper Reibel, Katalin Kiss, Morten Schioedt
      Abstract: NUT carcinomas (NC) are rare and aggressive tumours characterized by chromosomal rearrangements of the gene encoding for nuclear protein of the testis (NUT) located on chromosome 15q14. This article presents a case of a 60-year-old woman diagnosed with NC presenting as a fast growing primary tumour in the right palate. Further evaluation revealed a tumour mass in the lungs and widespread metastases. A review of the literature did not reveal earlier cases presenting in the palate. In order to improve early diagnosis it is suggested to perform immunohistochemical testing for NUT in all poorly differentiated carcinomas without glandular differentiation arising in the chest, and head and neck (Clin Cancer Res, 18, 2012, 5773).

  • Polymorphism of TLR5 rs5744174 is associated with disease progression in
           Chinese patients with chronic HBV infection
    • Authors: Lina Cao; Tong Zhang, Junping Zhu, Aixin Li, Kai Zheng, Nan Zhang, Bin Su, Wei Xia, Hao Wu, Ning Li, Qiushui He
      Abstract: Toll-like receptors (TLRs) play a crucial role in innate and adaptive immunity, protecting the host from viral pathogens. Studies have implicated that TLR5 is associated with various diseases such as autoimmune and inflammation related diseases. However, little is known about the relationship between TLR5 and hepatitis B virus (HBV) infection. We studied the effect of TLR5 gene polymorphisms on susceptibility to and disease progression of chronic hepatitis B (CHB) infection in Chinese. Blood samples were taken from 636 patients with CHB, HBV-related liver cirrhosis (LC) or hepatocellular carcinoma (HCC) and 273 controls. Polymorphisms of TLR5 (1775A>G rs2072493 and 1846T>C rs5744174) were analyzed by PCR-based sequencing. No difference in genotypic and allelic frequencies of TLR5 rs2072493 and rs5744174 was observed between patients and controls. Significant difference was found in frequency of TLR5 rs5744174 TT genotype between men with CHB and LC (p = 0.035). Frequency of TT genotype of TLR5 rs5744174 in patients positive for HBeAg was increased from 53.2% in patients with CHB to 74.1% in those with HCC (p = 0.024). Our results indicate that in Chinese genetic variation of TLR5 may be not a determinant of susceptibility to HBV-related diseases but may play a role in development of HBV-related severe liver diseases.

      Abstract: Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults. Its clinical course is typically indolent; however, based on a series of pathobiological, clinical, genetic, and phenotypic parameters, patient survival varies from less than 5 to more than 20 years. In this paper, we show for the first time that the expression of the interferon-inducible DNA sensor IFI16, a member of the PYHIN protein family involved in proliferation inhibition and apoptosis regulation, is associated with the clinical outcome in CLL. We studied 99 CLLs cases by immunohistochemistry and 10 CLLs cases by gene expression profiling. We found quite variable degrees of IFI16 expression among CLLs cases. Noteworthy, we observed that a reduced IFI16 expression was associated with a very poor survival, but only in cases with ZAP70/CD38 expression. Furthermore, we found that IFI16 expression was associated with a specific gene expression signature. As IFI16 can be easily detected by immunohistochemistry or flow cytometry, it may become a part of phenotypic screening in CLL patients if its prognostic role is confirmed in independent series.

  • HBV-specific CD4+ cytotoxic T cells in hepatocellular carcinoma are less
           cytolytic toward tumor cells and suppress CD8+ T cell-mediated antitumor
           immunity
    • Authors: Fanzhi Meng; Shoumei Zhen, Bin Song
      Abstract: In East Asia and sub-Saharan Africa, chronic infection is the main cause of the development of hepatocellular carcinoma, an aggressive cancer with low survival rate. Cytotoxic T cell-based immunotherapy is a promising treatment strategy. Here, we investigated the possibility of using HBV-specific CD4+ cytotoxic T cells to eliminate tumor cells. The naturally occurring HBV-specific cytotoxic CD4+ and CD8+ T cells were identified by HBV peptide pool stimulation. We found that in HBV-induced hepatocellular carcinoma patients, the HBV-specific cytotoxic CD4+ T cells and cytotoxic CD8+ T cells were present at similar numbers. But compared to the CD8+ cytotoxic T cells, the CD4+ cytotoxic T cells secreted less cytolytic factors granzyme A (GzmA) and granzyme B (GzmB), and were less effective at eliminating tumor cells. In addition, despite being able to secrete cytolytic factors, CD4+ T cells suppressed the cytotoxicity mediated by CD8+ T cells, even when CD4+CD25+ regulator T cells were absent. Interestingly, we found that interleukin 10 (IL-10)-secreting Tr1 cells were enriched in the cytotoxic CD4+ T cells. Neutralization of IL-10 abrogated the suppression of CD8+ T cells by CD4+CD25− T cells. Neither the frequency nor the absolute number of HBV-specific CD4+ cytotoxic T cells were correlated with the clinical outcome of advanced stage hepatocellular carcinoma patients. Together, this study demonstrated that in HBV-related hepatocellular carcinoma, CD4+ T cell-mediated cytotoxicity was present naturally in the host and had the potential to exert antitumor immunity, but its capacity was limited and was associated with immunoregulatory properties.

  • STAT3 promotes bone fracture healing by enhancing the FOXP3 expression and
           the suppressive function of regulatory T cells
    • Authors: Guojing Sun; Zhen Wang, Yunfan Ti, Yicun Wang, Jun Wang, Jianning Zhao, Hongbo Qian
      Abstract: Signal transducer and activator of transcription 3 (STAT3) is a key signaling protein in the skeletal system as well as in the immune system. Accumulating evidence demonstrates that the inflammatory response is deeply involved in the healing process of bone fractures, but how the immune system is regulated during this process is unclear. In this study, we examined STAT3-mediated regulation of immunity in adult patients with closed tibia fracture. In all patients, the expression and activation of STAT3 peaked at around day 7 to day 14 after surgery, and gradually decreased during the rest of the healing period. At day 7 (peak STAT3 expression and phosphorylation), the CD4+CD25+ T cells from bone fracture patients presented the highest level of STAT3 activation among lymphocyte subsets. Therefore, we investigated the role of STAT3 in CD4+CD25+ T cells. The level of FOXP3 expression by CD4+CD25+ T cells was directly correlated with the level of STAT3 phosphorylation in these cells. The level of STAT3 phosphorylation in CD4+CD25+ T cells was also inversely correlated with the level of IFN-γ and TNF-α secretion in peripheral blood mononuclear cells. Inhibition of STAT3 significantly suppressed FOXP3 and IL-10 expression by CD4+CD25+ T cells, as well as the ability of CD4+CD25+ T cells to suppress T-cell IFN-γ and TNF-α secretion. Furthermore, early healers patients presented significantly higher STAT3 expression and phosphorylation than late healers, possibly due to the higher IL-6 and IL-10 levels in the serum of early healing patients. Together, these data demonstrated that STAT3 was beneficial to bone fracture healing, possibly by enhancing Treg-mediated suppression of counteracting inflammations, and suggested that STAT3 could be used as a prognostic marker to identify otherwise undistinguishable patients at risk of developing delayed union or nonunion.

  • PKC, ERK/p38 MAP kinases and NF-κB targeted signalling play a role in the
           expression and release of IL-1β and CXCL8 in Porphyromonas
           gingivalis-infected THP1 cells
    • Authors: Kartheyaene Jayaprakash; Isak Demirel, Sezin Gunaltay, Hazem Khalaf, Torbjörn Bengtsson
      Abstract: Porphyromonas gingivalis is a keystone pathogen in periodontitis and is gaining importance in cardiovascular pathogenesis. Protease-activated receptors (PARs), toll-like receptors (TLRs) and nucleotide-binding oligomerization domain (NOD) on monocytes recognize the structural components on P. gingivalis, inducing inflammatory intermediates. Here, we elucidate the modulation of PARs, TLRs, NODs, and the role of MAPK and NF-κB in IL-1β and CXCL8 release. THP1 cells were stimulated with P. gingivalis wild-type W50 and its isogenic gingipain mutants: Rgp mutant E8 and Kgp mutant K1A. We observed modulation of PARs, TLRs, NOD, IL-1β and CXCL8 expression by P. gingivalis. Gingipains hydrolyse IL-1β and CXCL8, which is more evident for IL-1β accumulation at 24 h. Inhibition of PKC (protein kinase C), p38 and ERK (extracellular signal-regulated kinases) partially reduced P. gingivalis-induced IL-1β at 6 h, whereas PKC and ERK reduced CXCL8 at both 6 and 24 h. Following NF-κB inhibition, P. gingivalis-induced IL-1β and CXCL8 were completely suppressed to basal levels. Overall, TLRs, PARs and NOD possibly act in synergy with PKC, MAPK ERK/p38 and NF-κB in P. gingivalis-induced IL-1β and CXCL8 release from THP1 cells. These pro-inflammatory cytokines could affect leucocytes in circulation and exacerbate other vascular inflammatory conditions such as atherosclerosis.

      Abstract: Janibacter hoylei has previously been isolated only from an air sample in the upper atmosphere and clinical significance of J. hoylei was not yet established. Herein, we report a case of bacteremia caused by J. hoylei. An 8-week-old previously healthy male infant presented to the emergency room with fever. Blood culture yielded growth of Gram-positive bacilli and this microorganism could not be identified with conventional phenotypic methods. The isolate was identified by 16S rRNA gene sequencing, and the patient was successfully treated with vancomycin. To our knowledge, this is the first report of the recovery of J. hoylei in humans. This case shows that J. hoylei can be a potential pathogen in young children.

           polarization to Th-17 pattern: an experience on HIV-1 vaccine model

      Abstract: Cytokines are mediators for polarization of immune response in vaccines. Studies show that co-immunization of DNA vaccines with granulocyte-macrophage colony-stimulating factor (GM-CSF) can increase immune responses. Here, experimental mice were immunized with HIV-1tat/pol/gag/env DNA vaccine with GM-CSF and boosted with recombinant vaccine. Lymphocyte proliferation with Brdu and CTL activity, IL-4, IFN-γ, IL-17 cytokines, total antibody, and IgG1 and IgG2a isotypes were assessed with ELISA. Results show that GM-CSF as adjuvant in DNA immunization significantly increased lymphocyte proliferation and IFN-γ cytokines, but CTL response was tiny increased. Also GM-CSF as adjuvant decreased IL-4 cytokine vs mere vaccine group. IL-17 in the group that immunized with mixture of DNA vaccine/GM-CSF was significantly increased vs DNA vaccine group. Result of total antibody shows that GM-CSF increased antibody response in which both IgG1 and IgG2a increased. Overall, results confirmed the beneficial effect of GM-CSF as adjuvant to increase vaccine immunogenicity. The hallmark result of this study was to increase IL-17 cytokine with DNA vaccine/GM-CSF immunized group. This study for the first time provides the evidence of the potency of GM-CSF in the induction of IL-17 in response to a vaccine, which is important for control of infection such as HIV-1.

  • Cryo scanning electron microscopy of Plasmodium falciparum-infected
           erythrocytes
    • Authors: Casper Hempel
      Abstract: Plasmodium falciparum invades erythrocytes as an essential part of their life cycle. While living inside erythrocytes, the parasite remodels the cell's intracellular organization as well as its outer surface. Late trophozoite-stage parasites and schizonts introduce numerous small protrusions on the erythrocyte surface, called knobs. Current methods for studying these knobs include atomic force microscopy and electron microscopy. Standard electron microscopy methods rely on chemical fixation and dehydration modifying cell size. Here, a novel method is presented using rapid freezing and scanning electron microscopy under cryogenic conditions allowing for high resolution and magnification of erythrocytes. This novel technique can be used for precise estimates of knob density and for studies on cytoadhesion.

           molecule-4 in hepatocellular carcinoma
    • Authors: Hyeyoon Chang; Wonkyung Jung, Aeree Kim, Han Kyeom Kim, Wan Bae Kim, Ji Hoon Kim, Baek-hui Kim
      Abstract: Hepatocellular carcinoma (HCC) is one of the most common malignancies and causes of death worldwide. In this study, we assessed the correlation between clinicopathologic factors with programmed cell death protein 1 (PD-1) and programmed cell death ligand-1 (PD-L1), and cytotoxic T lymphocyte-associated molecule-4 (CTLA-4) expressions. Furthermore, we analyzed the prognostic significance of these proteins in a subgroup of patients. We retrospectively evaluated the PD-1, PD-L1, and CTLA-4 expressions in 294 HCC tissue microarray samples using immunohistochemistry. PD-1 and PD-L1 expressions were significant related to high CD8+ tumor-infiltrating lymphocytes (TILs) (r = 0.664, p < 0.001 and r = 0.149, p = 0.012). Only high Edmondson–Steiner grade was statistically related to high PD-1 expression. High PD-L1 expression was demonstrated as an independent poor prognostic factor for disease-free survival in addition to previous known factors, size>5 cm and serum albumin ≤3.5 g/dL in high CD8+ TILs group. We have demonstrated that the combined high expression of PD-L1 and CD8+ TIL is an important prognostic factor related to the immune checkpoint pathway in HCC and furthermore, there is a possibility that it could be used as a predictor of therapeutic response. Also, this result would be helpful in evaluating the applicable group of PD-1/PD-L1 blocking agent for HCC patients.

    • Authors: Bharat Rekhi; Kemal Kosemehmetoglu, Gaye Guler Tezel, Sergulen Dervisoglu
      Abstract: Epithelioid malignant peripheral nerve sheath tumor (MPNST) is a rare, relatively less chemosensitive sarcoma. We report clinicopathologic features of 11 epithelioid MPNSTs, including rare forms, along with INI1 immunostaining and BRAF V600E mutation results. BRAF V600E mutation was tested by Real-time polymerase chain reaction (PCR) technique. Eleven tumors occurred in six men and five women (M:F ratio = 0.85:1) within an age range of 5–73 years (average = 44), mostly in lower limbs (five), followed by upper limbs (four). Tumor size (n = 6), varied from 3.1 to 15 cm (average = 8.3). Histopathologically, most tumors were multilobular, characterized by epithelioid to round-shaped, malignant cells, along with spindle cells (three cases), “rhabdoid-like” cells (seven cases) and pleomorphic giant cells (single case). By immunohistochemistry, tumor cells were positive for S100 protein (11/11) (100%), EMA (3/7) (42.8%), pan CK(2/7) (28.5%), and HMB45 (1/11) (9%), while these were negative for Melan A (0/11) and INI1 (3/11), including a single tumor, displaying HMB45 positivity. BRAF V600E mutation was positive in 1/8 cases, that lacked melanocytic marker expression. All patients (n = 5) were treated by surgical resection. During follow-up (n = 8, median duration = 23 months), four patients developed tumor recurrences and four developed metastasis, mostly to lymph nodes (3). Finally, four patients were alive with disease, two were alive with no evidence of disease, and two patients died of disease. Epithelioid MPNSTs have a diverse histopathologic spectrum. Loss of INI1 is useful, including in identifying rare forms of epithelioid MPNST, displaying melanocytic differentiation. Most tumors are treated by surgical resection. Loss of INI1 and the presence of BRAF V600E mutation in some cases raises future possibility of exploring targeted therapy in those, rare epithelioid MPNSTs.

      Abstract: The antifungal effects of ambroxol (Amb; the metabolite VIII of bromhexine) against Cryptococcus planktonic cells and mature biofilms were investigated in this study. Amb showed antifungal activity against planktonic cells and mature biofilms. Disk diffusion test similarly showed antifungal profile for planktonic cells. Furthermore, Amb was found to be synergetic with fluconazole against planktonic cells and reduced the adherence of cells to polystyrene. Our results suggest that Amb can inhibit cryptococcal cells and biofilms, indicating its potential role in the prevention and treatment of cryptococcosis.

  • A five-miRNA expression signature predicts survival in hepatocellular
           carcinoma
    • Authors: Gang Liu; Hui Wang, Jin-dong Fu, Jing-ying Liu, Ai-guo Yan, Yan-yan Guan
      Abstract: The aim of this study was to identify a microRNA (miRNA) expression signature for predicting HCC (hepatocellular carcinoma) survival. A total of 322 HCC patients in The Cancer Genome Atlas (TCGA) database were randomly divided into training and testing set. miRNAs, associated with survival time in the training set, were identified by using univariate Cox regression analysis. The risk score was formulated based on the expression levels of these miRNAs. Then the miRNA signature was validated in testing set through Kaplan–Meier analysis and log-rank test. hsa-miR-301a, hsa-miR-132, hsa-miR-212, hsa-miR-489, and hsa-miR-1468 were identified to formulate risk score in training set and used to calculate the risk score of each patients in testing set. About 161 patients in testing set were segregated into high- and low-risk group according to the median risk score. The survival time of high-risk group was significantly shorter (p = 0.0248) than low-risk group in testing test. The target genes of five miRNAs were significantly enriched in valine, leucine, and isoleucine degradation pathway and PPAR signaling pathway. hsa-miR-1468 had an up-regulated tendency in HCC tissues compared to adjacent tumor tissues. The expression of hsa-miR-301a, hsa-miR-132, hsa-miR-212, hsa-miR-489, and hsa-miR-1468, which might be potential biomarkers to evaluate HCC patients' prognosis.

      Abstract: Nonalcoholic fatty liver disease (NAFLD) is a spectrum of liver disorders ranging from simple hepatic steatosis up to nonalcoholic steatohepatitis (NASH) evolving to cirrhosis and hepatocellular carcinoma (HCC). Liver biopsy is still the gold standard modality for diagnosing and staging NAFLD. The linkage between intestinal microbiota and NAFLD, might suggest a potential role of serum zonulin in NAFLD diagnosis. To appraise the role of circulating zonulin in NAFLD pathogenesis, 56 subjects with proved NAFLD by ultrasonography and liver biopsy, as well as 20 healthy controls were tested. Liver function tests, serum glucose, fasting insulin, C peptide, lipid profile, homeostasis model assessment of insulin resistance (HOMA-IR), IL-6, and circulating zonulin were performed to all subjects. Aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transferase (GGT), triglycerides, HDL-c, fasting insulin, C peptide, HOMA-IR, IL-6, and serum zonulin were higher in NAFLD group than in controls (p

  • Assessment of biofilm removal capacity of a broad host range bacteriophage
           JHP against Pseudomonas aeruginosa
    • Authors: Muafia Shafique; Iqbal Ahmad Alvi, Zaigham Abbas, Shafiq Rehman
      Abstract: Pseudomonas aeruginosa is an efficient biofilm-dwelling microbial pathogen, associated with nosocomial infections. These biofilm-associated infections are resistant to antibiotics and immune defenses, therefore pose major problem against their treatment. This scenario demands alternative therapeutic regimens, and bacteriophage therapy is one among potential strategies for clinical management of multiple drug resistance. In this investigation, the efficacy of a bacteriophage, JHP, is evaluated to eradicate P. aeruginosa biofilms. Growth kinetics of P. aeruginosa biofilm revealed that the highest cell density biofilm (1.5 × 1016 CFU/mL) was established within the polystyrene microtiter plate at 72 h post inoculation. Pseudomonas aeruginosa biofilms of different ages, treated with JHP (0.6 MOI) for different post-infection durations, reduced biomass from 2 to 4.5 logs (60–90%). JHP treatment before biofilm development reduced the bacterial load up to 9 logs (>95% bacterial load reduction) as compared with untreated control, which highlights its potential to prevent biofilm formation in indwelling medical devices. Combinations of JHP with other phages or antibiotics could be an efficient alternative for P. aeruginosa biofilm removal in clinical and industrial settings.

           N-(3-oxododecanoyl)-L-homoserine lactone from Pseudomonas aeruginosa
    • Authors: Lei Bao; Jialin Yu, Haiying Zhong, Daochao Huang, Qi Lu
      Abstract: The establishment of chronic Pseudomonas aeruginosa infections is correlated with the disturbance of the host immune system. The P. aeruginosa quorum-sensing molecule N-3-(oxododecanoyl)-L-homoserine lactone (3-O-C12-HSL) has the potential to modulate the host immune system. The immune system recognizes pathogens via toll-like receptors (TLRs). We found that 3-O-C12-HSL induced TLR changes in monocytes. However, the role of T cells in P. aeruginosa infection has not been delineated. In order to understand this activity, we examined whether 3-O-C12-HSL has an effect on the immune function and the expression of TLRs in T lymphocytes. Human peripheral blood mononuclear cells (PBMCs) cells were cultured with 0, 1, 10, 50, or 100 μM 3-O-C12-HSL for 12 h. TLR2/TLR4 expression and T-lymphocyte proliferation were increased in a dose-dependent manner, and 100 μM 3-O-C12-HSL significantly increased TLR2 expression. Moreover, tumor necrosis factor-α production of these PBMCs was inhibited. To conclude, 3-O-C12-HSL can induce lymphocyte cell proliferation. These findings provide a new perspective on our understanding of the persistence of the chronic inflammation that accompanies P. aeruginosa infection.

           antigen-specific immune responses in vitro and in vivo
    • Authors: Saeme Asgari; Azadeh Ebrahim-Habibi, Mehdi Mahdavi, Mohammad Choopani, Hasan Mirzahoseini
      Abstract: Hirudin III is an effective anti-coagulant; however, in 40% of treated patients, a high-titer of anti-Hirudin III IgG antibodies is observed. Development of antibody responses requires the activation of helper T lymphocyte (HTL), which is dependent on peptide epitopes binding to HLA class II molecules. Based on computational prediction softwares, four new mutants of Hirudin III, T4K, S9G, V21G, and V21K, had been designed with the aim of reducing the binding affinity of these HTL epitopes. The constructed mutants have been purified and assayed for bioactivity. Finally in vitro and in vivo cell-mediated responses were assessed and humoral immune assays were performed. All modified forms of Hirudin III were active, and showed significantly reduced human T-cell responses. All mutants indicated lower human IFN-γ level compared to native Hirudin, and V21K indicated lowest IFN-γ level. Mice immunized with T4K and V21K showed a significant reduction in total antibody responses and mouse IFN-γ levels. Mice immunized with V21K after 3rd immunization had lower T-cell proliferation compared to native Hirudin and other mutants. Based on these results, V21K is proposed as the best alternate Hirudin III candidate with lowest antigenicity. These findings validate our rational design strategy aimed at providing new active analogs of therapeutic proteins with reduced immunogenicity.

Variations in the genes encoding these enzymes may influence the activity of corresponding metabolizing enzymes. This study aimed at assessing association of CYP2C9*2 430C/T, CYP2C9*31075A/C, and CYP1A1m1 3801T/C polymorphism with risk to develop ARV Antiretroviral-associated hepatotoxicity and its severity. In this case–control study, genotyping of CYP2C9*2, CYP2C9*3, and CYP1A1m1 genes was done in 34 HIV-infected individuals with hepatotoxicity and 131 without hepatotoxicity, and 153 unrelated healthy individuals using PCR-RFLP. CYP1A1m13801CC genotype was likely to be associated with severe ARV-associated hepatotoxicity (OR = 1.78, p = 0.70). CYP1A1m13801CC genotype and combined genotype TC + CC were likely to be associated with development of ARV-associated hepatotoxicity (OR = 2.57, p = 0.08; OR = 1.42, p = 0.17). CYP1A1m1 3801CC genotype among advanced and intermediate HIV disease stage was likely to be associated with advancement of disease (OR = 2.56, p = 0.77; OR = 2.37, p = 0.45). CYP2C9*31075AC genotype among alcohol users was likely to be associated with development of ARV-associated hepatotoxicity (OR = 1.67, p = 0.38). CYP1A1m1 3801TC genotype and combined genotype TC + CC among nevirapine users were likely to be associated with severe ARV-associated hepatotoxicity (OR = 3.68, p = 0.27; OR = 4.91, p = 0.13). Among those who received nevirapine, presence of CYP1A1m1 3801TC genotype was likely to be associated with increased risk of development of ARV-associated hepatotoxicity (OR = 1.50, p = 0.78). CYP1A1m1 3801TC, 3801CC, and CYP2C9*3 1075AC genotypes among combined alcohol + nevirapine users increased the risk of development of ARV-associated hepatotoxicity (OR = 1.41, p = 0.53; OR = 1.49, p = 0.83; OR = 1.78, p = 0.35). In conclusion, individuals with CYP1A1m13801CC and 3801TC genotypes independently and in the presence of alcohol and nevirapine usage is likely to be associated with increased risk of development of ARV-associated hepatotoxicity, its severity, and advancement of disease. CYP2C9*31075AC genotype with combined alcohol and nevirapine usage indicated a risk for development of ARV-associated hepatotoxicity.

  • Chondroid lipoma associated with osteoclast-like multinucleated giant
           cells – a case report
    • Authors: Mohammed Alyousef; Areej Al Nemer
      Abstract: Chondroid lipoma is a rare soft tissue neoplasm. We report case of chondroid lipoma associated with osteoclast-like multinucleated giant cells. To the best of our knowledge, the presence of these giant cells has not been previously described in the English literature. The recognition of these cells is important and their occurrence in this rare neoplasm should not mislead the pathologist to misdiagnose this entity.

  • Apoptotic pathways of macrophages within osteolytic interface membrane in
           periprosthestic osteolysis after total hip replacement
    • Authors: Guoyin Liu; Ting Guo, Yong Zhang, Naicheng Liu, Jiangning Chen, Jianmin Chen, Junfeng Zhang, Jianning Zhao
      Abstract: Macrophage apoptosis in interface membrane, which occurs through either death receptor, mitochondrion, or endoplasmic reticulum (ER) stress pathways, has been suggested to play an important role in promoting osteolysis. However, how and why macrophage apoptosis originates and the correlation among these apoptotic pathways is not yet clear. The objective of this study was to identify the apoptotic mechanism of macrophages, and to explore the relationship between the apoptotic pathways and progression of osteolysis. Transmission electron microscopy (TEM) was utilized to analyze the tissue ultrastructure of wear particles, and in situ apoptotic macrophage identification was performed by TUNEL staining. We analyzed the expression of the key biomarkers of apoptotic pathways via immunohistochemistry and Western blotting. Our results demonstrated that the majority of wear particles within osteolytic interface membrane was in the 30–60 nm range, and that macrophage apoptotic ratio increased along with osteolysis progression. Normal hip dysplasia and mechanical loosening of tissues showed low expression levels of biomarkers for ER stress (Ca2+, JNK, cleaved Caspase-4, IRE1-α, Grp78/Bip, and CHOP), mitochondrion (Bcl-2, Bax, and Cytochrome c), and death receptor (Fas and cleaved Caspase-8) pathways, while osteolytic interface membrane tissues expressed high levels of these biomarkers. In addition, we found that the ER stress intensity was in complete conformity with mitochondrial dysfunction and was consistent with the results of death receptor activation. Thus, our findings suggested that wear particles generated at implant interface can accelerate macrophage apoptosis through changes in apoptotic pathways and ultimately aggravate the symptom of osteolysis. These data represent a preferential apoptotic signaling pathway of macrophages as specific target points for the prevention and therapeutic modulation of periprosthetic osteolysis.

  • Toll-like receptor-2 Arg753Gln and Arg677Trp polymorphisms and
           susceptibility to pulmonary and peritoneal tuberculosis
    • Authors: Mohammed A. Saleh; Mahmoud M. Ramadan, Eman O. Arram
      Abstract: Recent evidence suggests that toll-like receptor-2 (TLR2) is important for host defense against Mycobacterium tuberculosis (MTB). TLR2 polymorphisms have shown significant impact on susceptibility or resistance to tuberculosis (TB). This case–control study aims to determine the influence of TLR2 (Arg753Gln and Arg677Trp) polymorphisms on the susceptibility to develop pulmonary or peritoneal TB. Genotyping of TLR2 (Arg753Gln and Arg677Trp) polymorphisms was carried out on 52 patients with pulmonary TB, 44 patients with peritoneal TB, and 50 healthy controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). There was a significant association between the GA genotype (heterozygous mutant) of TLR2 Arg753Gln polymorphism and the risk of infection with pulmonary TB (p = 0.003, OR = 4.83) and TB peritonitis (p = 0.003, OR = 6.2). Differences in the genotype frequencies of TLR2 Arg677Trp polymorphisms between patients with pulmonary or peritoneal TB and healthy controls were not detected. GA753 TLR2 polymorphism may play a role in the susceptibility to pulmonary and peritoneal TB infection. Further studies on a large number of ethnically diverse patient cohorts may help to confirm the possible effect of these polymorphisms on the susceptibility to pulmonary and peritoneal TB.

  • Citrate attenuates vascular calcification in chronic renal failure rats
    • Authors: Yan Ou; Zengying Liu, Shuiqin Li, Xiaojing Zhu, Yan Lin, Jin Han, Zhaoyang Duan, Lining Jia, Baosong Gui
      Abstract: Vascular calcification (VC) is a major contributor of cardiovascular dysfunction in chronic renal failure (CRF). Citrate binds calcium and inhibits the growth of calcium crystals. This present study intends to evaluate the effect of citrate on VC in adenine-induced CRF rats. The rats were randomly divided into five groups: the control group, the citrate control group, model group, model rats with low-dose treatment of citrate (216 mg/kg) and model rats with high-dose treatment of citrate (746 mg/kg). The rats were euthanized at 5 weeks with their blood and aorta in detection. The results showed that serum level of blood urea nitrogen, serum creatinine, phosphorus, calcium, and related renal failure function marker were elevated in the model group. Furthermore, the aortic calcium accumulation and alkaline phosphatase activity were significantly increased in the model group compared with control groups. Additionally, hematoxylin–eosin staining results demonstrated that the vascular calcification in aorta is significantly increased in the model group. Finally, the expression of VC-related proteins including bone morphogenetic protein and osteocalcin were increased in the model group, whereas alpha-smooth muscle actin was decreased in the model group compared with the control group. However, treatment with citrate caused a reversal effect of all the above events in a dose-dependent manner. In conclusion, citrate may attenuate vascular calcification in adenine-induced CRF rats.

  • Evaluation of phytochemicals from medicinal plants of Myrtaceae family on
           virulence factor production by Pseudomonas aeruginosa
    • Authors: Khadar Syed Musthafa; Wipawadee Sianglum, Jongkon Saising, Sakkarin Lethongkam, Supayang Piyawan Voravuthikunchai
      Abstract: Virulence factors regulated by quorum sensing (QS) play a critical role in the pathogenesis of an opportunistic human pathogen, Pseudomonas aeruginosa in causing infections to the host. Hence, in the present work, the anti-virulence potential of the medicinal plant extracts and their derived phytochemicals from Myrtaceae family was evaluated against P. aeruginosa. In the preliminary screening of the tested medicinal plant extracts, Syzygium jambos and Syzygium antisepticum demonstrated a maximum inhibition in QS-dependent violacein pigment production by Chromobacterium violaceum DMST 21761. These extracts demonstrated an inhibitory activity over a virulence factor, pyoverdin, production by P. aeruginosa ATCC 27853. Gas chromatography–mass spectrometric (GC-MS) analysis revealed the presence of 23 and 12 phytochemicals from the extracts of S. jambos and S. antisepticum respectively. Three top-ranking phytochemicals, including phytol, ethyl linoleate and methyl linolenate, selected on the basis of docking score in molecular docking studies lowered virulence factors such as pyoverdin production, protease and haemolytic activities of P. aeruginosa to a significant level. In addition, the phytochemicals reduced rhamnolipid production by the organism. The work demonstrated an importance of plant-derived compounds as anti-virulence drugs to conquer P. aeruginosa virulence towards the host.

  • Carbapenemases-producing Klebsiella pneumoniae in hospitals of two regions
           of Southern Italy
    • Authors: Carla Calia; Carlo Pazzani, Marta Oliva, Maria Scrascia, Piero Lovreglio, Carmen Capolongo, Anna Maria Dionisi, Adriana Chiarelli, Rosa Monno
      Abstract: Carbapenem-resistant Klebsiella pneumoniae infections are reported with increasing frequency elsewhere in the world, representing a worrying phenomenon for global health. In Italy, there are hotspot data on the diffusion and type of carbapenemase-producing Enterobacteriaceae and K. pneumoniae in particular, with very few data coming from Apulia and Basilicata, two regions of Southern Italy. This study was aimed at characterizing by phenotypic and genotypic methods carbapenem-resistant K. pneumoniae isolated from several Hospitals of Apulia and Basilicata, Southern Italy. Antibiotic susceptibility was also evaluated. The relatedness of carbapenemase-producing K. pneumoniae strains was established by pulsed-field gel electrophoresis (PFGE). Among the 150 K. pneumoniae carbapenemase producers, KPC-3 genotype was the most predominant (95%), followed by VIM-1 (5%). No other genotypes were found and no co-presence of two carbapenemase genes was found. A full concordance between results obtained by both the phenotypic and the genotypic tests was observed. All strains were resistant to β-lactam antibiotics including carbapenems, and among antibiotics tested, only tetracycline and gentamycin showed low percentage of resistance (18% and 15%, respectively). Resistance to colistin was detected in 17.3% of strains studied. The analysis of PFGE profiles of the carbapenemases-positive strains shows that one group (B) of the five (A to E) main groups identified was the most prevalent and detected in almost all the hospitals considered, while the other groups were randomly distributed. Three different sequence types (ST 307, ST 258, and ST 512) were detected with the majority of isolates belonging to the ST 512. Our results demonstrated the wide diffusion of K. pneumoniae KPC-3 in the area considered, the good concordance between phenotypic and genotypic tests. Gentamicin and colistin had a good activity against these strains.

  • Dissemination of metallo-β-lactamase in Pseudomonas aeruginosa isolates
           in Egypt: mutation in blaVIM-4
    • Authors: Hany Hashem; Amro Hanora, Salah Abdalla, Alaa Shaeky, Alaa Saad
      Abstract: This study was designed to investigate the prevalence of metallo-β-lactamase (MBL) in Pseudomonas aeruginosa isolates collected from Suez Canal University Hospital in Ismailia, Egypt. Antibiotic susceptibility testing and phenotypic and genotypic screening for MBLs were performed on 147 isolates of P. aeruginosa. MICs were determined by agar dilution method for carbapenem that was ≥2 μg/mL for meropenem. MBL genes were detected by multiplex and monoplex PCR for P. aeruginosa-harbored plasmids. Mutation profile of sequenced MBL genes was screened using online software Clustal Omega. Out of 147 P. aeruginosa, 39 (26.5%) were carbapenem-resistant isolates and 25 (64%) were confirmed to be positive for MBLs. The susceptibility rate of P. aeruginosa toward polymyxin B and norfloxacin was 99% and 88%, respectively. Identification of collected isolates by API analysis and constructed phylogenetic tree of 16S rRNA showed that the isolates were related to P. aeruginosa species. The frequency of blaGIM-1, blaSIM-1, and blaSPM-1 was 52%, 48%, and 24%, respectively. BlaVIM and blaIMP-like genes were 20% and 4% and the sequences confirm the isolate to be blaVIM-1, blaVIM-2, blaVIM-4, and blaIMP-1. Three mutations were identified in blaVIM-4 gene. Our study emphasizes the high occurrence of multidrug-resistant P. aeruginosa-producing MBL enzymes.

  • The prevalence of HPV infections in HPV-vaccinated women from the general
           population
    • Authors: Eva Hamsikova; Jana Smahelova, Viera Ludvikova, Martina Salakova, Jana Rychla, Jana Skrenkova, Lukas Rob, Ruth Tachezy
      Abstract: Currently, three prophylactic HPV vaccines are commercially available to prevent HPV 16/18 infection and associated lesions. The aim of the study was to assess markers of HPV infection in women/girls before vaccination and to ascertain the prevalence and spectrum of post-vaccination HPV types. Three hundred and thirty subjects of which 75 were virgins were enrolled. Before the first dose of the HPV vaccine and 1, 3 and 5 years after the completion of HPV vaccination, the samples for cytology, HPV detection and anti-HPV antibody response were taken. At enrolment, HPV DNA was detected in 38% of sexually active girls/women. At the first, second and third follow-up, HPV DNA was found in 40, 45, and 39% of them. The seroprevalence rates to HPV 6, 11, 16 and 18 in these subjects were 31, 21, 18 and 10%. On the follow-up significantly higher levels of antibodies to HPV 16/18 were found after application of divalent vaccine. Results of the study demonstrate high prevalence of HPV infection in young women. In a substantial number of women, HPV-specific antibodies as well as high-risk HPV types were detected. HPV-specific antibodies were also frequently found in non-sexually active girls. The acquisition of HPV after the onset of sexual life was very fast.

  • Tumor necrosis factor-α −308G/A and −238G/A polymorphisms are
           associated with increased risks of sepsis: evidence from an updated
           meta-analysis
    • Authors: Mu Zhang; Yu Zhao, Qiong Liu
      Abstract: Previous studies have reported the relationship between tumor necrosis factor-α (TNF-α) −308G/A and −238G/A polymorphisms and sepsis risk with inconsistent results. The aim of this study was to estimate the association of the two polymorphisms with risk of sepsis or sepsis-related mortality using a meta-analysis. PubMed, Embase, and Web of Science databases were searched up to June 20 2016. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed or random effect model. Twenty-six studies were included in this meta-analysis. Overall, an increased sepsis risk of TNF-α −308G/A was observed (GA vs GG: OR = 1.43, 95% CI: 1.07–1.92; GA/AA vs GG: OR = 1.42, 95% CI: 1.06–1.89). Subgroup analyses showed that the significant association was found in Asians (GA vs GG: OR = 1.63, 95% CI: 1.01–2.63) and adult patients. Similarly, an increased sepsis risk of TNF-α −238G/A was observed in overall and subgroup analyses. However, no significant association was found between TNF-α −308G/A and −238G/A polymorphisms and sepsis-related mortality. These findings indicate that both TNF-α −308G/A and −238G/A polymorphisms were associated with increased risks of sepsis but not sepsis-related mortality. Further studies with larger sample size are needed to confirm these results.

  • Circulating syndecans during critical illness
    • Authors: Axel Nelson; Joakim Johansson, Jonas Tydén, Mikael Bodelsson
      Abstract: Circulating syndecans are proposed to be markers of glycocalyx degradation and previous investigations have found higher plasma levels of syndecan-1 among patients with different pathological conditions. We wanted to investigate if levels of other syndecans (-2,-3 and -4) are altered during critical illness and compare the levels to syndecan-1. In 137 consecutive intensive care unit (ICU) patients with sepsis, cardiac arrest, gastrointestinal bleeding, intoxication or trauma, plasma levels of syndecan-1, -2, -3 and -4 were measured using ELISA. Syndecan-1 and syndecan-3 levels were similar among the different ICU patient groups but higher than controls. No differences in plasma levels of syndecan-2 or syndecan-4 were found neither among the different ICU patient groups nor compared to controls. All syndecans showed an association with mortality and the levels of syndecan-1 and -3 and correlated with each other. The results indicate that syndecan release is triggered by the physiological stress of critical illness in general and involves several subtypes such as syndecan-1 and syndecan-3.

  • Significant variations in the seroprevalence of C6 ELISA antibodies in a
           highly endemic area for Lyme borreliosis: evaluation of age, sex and
           seasonal differences
    • Authors: Marcus Johansson; Lena Manfredsson, Annika Wistedt, Lena Serrander, Ivar Tjernberg
      Abstract: The purpose of this study was to assess the seroprevalence of C6 ELISA antibodies in healthy blood donors in Kalmar County, Sweden, in relation to age, sex and time of year (peak season vs off season). In addition, we wanted to assess serological status over time in a group of C6 ELISA seropositive blood donors. Sera were collected from 273 (131 women, 142 men) blood donors in autumn 2011 and 300 (144 women, 156 men) in winter 2014. All sera were analysed in the C6 ELISA and the results were interpreted according to the manufacturer′s instructions. The seroprevalence was 22% (females 16%, males 28%) in 2011 and 24% (females 15%, males 33%) in 2014. The seroprevalence was significantly higher in males and increased with age. The highest seroprevalence was observed among elderly men, 60–70 years old (46% in 2011 and 52% in 2014). No significant difference was detected in seropositivity between the samples collected in winter and autumn. All (34/34) seropositive blood donors followed over time remained seropositive at follow-up after 22–29 months. C6 ELISA seroprevalence in healthy blood donors is high in Kalmar County, thereby reducing the specificity of a positive test result regarding the clinical diagnosis of Lyme borreliosis (LB). Although C6 seroprevalence appears not to be affected by seasonal sample time, it varies greatly with age and sex. A careful evaluation of pre-test probability is therefore of the utmost importance in the clinical diagnosis of LB, especially in elderly men. We suggest that colleagues in other endemic regions also consider initiating similar evaluations to optimize the laboratory and clinical diagnosis of LB in relation to age and sex.

    • Authors: Nadia Ben Fredj; Mouna Aissi, Walid Ben Selma, Imen Mahmoud, Faten Nefzi, Mahbouba Frih-Ayed, Jalel Boukadida, Mahjoub Aouni
      Abstract: Interleukin-10 (IL-10), a potent anti-inflammatory T-cell cytokine, has been shown to be a regulatory cytokine that is associated with disease remission in multiple sclerosis (MS) and exerts its activity through its cognate cell surface receptor complex, IL-10 receptor 1 (IL-10R1) and IL-10R2. The purpose of this study was to investigate the IL-10R1 S138G loss-of-function polymorphism (A536G: rs3135932) for possible influence on susceptibility and outcome of MS in Tunisian patients. A total of 103 Tunisian MS patients and 160 control subjects were studied. Genomic DNA samples were extracted from leukocytes and used to investigate S138G polymorphism in IL-10R1 gene by multiplex allele-specific polymerase chain reaction. Associations between G allele [odds ratio (OR) = 5.57; 95% confidence intervals (CI) = 3.26–9.54; p = 10−7], GG genotypes [OR = 10.41; 95% CI = 2.28–47.58; p = 0.0007] and AG genotype [OR = 4.14; 95% CI = 2.16–7.93; p = 0.000016] with the risk development of MS were found. In contrast, the AA genotype seemed to be associated with protection against MS [OR = 0.17; 95% CI = 0.09–0.30; p = 10−7]. No association was found between S138G SNP and clinical features or disease activity of MS patients. In conclusion, our results suggest that S138G loss-of-function polymorphism of the IL-10R1 may be important risk factor in increasing susceptibility to MS.

           and reactive urothelial proliferation in bladder washings: a logistic
           regression analysis
    • Authors: Ebru Cakir; Ulku Kucuk, Emel Ebru Pala, Ozlem Sezer, Rahmi Gokhan Ekin, Ozgur Cakmak
      Abstract: Conventional cytomorphologic assessment is the first step to establish an accurate diagnosis in urinary cytology. In cytologic preparations, the separation of low-grade urothelial carcinoma (LGUC) from reactive urothelial proliferation (RUP) can be exceedingly difficult. The bladder washing cytologies of 32 LGUC and 29 RUP were reviewed. The cytologic slides were examined for the presence or absence of the 28 cytologic features. The cytologic criteria showing statistical significance in LGUC were increased numbers of monotonous single (non-umbrella) cells, three-dimensional cellular papillary clusters without fibrovascular cores, irregular bordered clusters, atypical single cells, irregular nuclear overlap, cytoplasmic homogeneity, increased N/C ratio, pleomorphism, nuclear border irregularity, nuclear eccentricity, elongated nuclei, and hyperchromasia (p ˂ 0.05), and the cytologic criteria showing statistical significance in RUP were inflammatory background, mixture of small and large urothelial cells, loose monolayer aggregates, and vacuolated cytoplasm (p ˂ 0.05). When these variables were subjected to a stepwise logistic regression analysis, four features were selected to distinguish LGUC from RUP: increased numbers of monotonous single (non-umbrella) cells, increased nuclear cytoplasmic ratio, hyperchromasia, and presence of small and large urothelial cells (p = 0.0001). By this logistic model of the 32 cases with proven LGUC, the stepwise logistic regression analysis correctly predicted 31 (96.9%) patients with this diagnosis, and of the 29 patients with RUP, the logistic model correctly predicted 26 (89.7%) patients as having this disease. There are several cytologic features to separate LGUC from RUP. Stepwise logistic regression analysis is a valuable tool for determining the most useful cytologic criteria to distinguish these entities.

  • Monocyte and lymphocyte surface molecules in severe sepsis and non-septic
           critically ill Patients
    • Authors: Joel Jämsä; Hannu Syrjälä, Virva Huotari, Eeva-Riitta Savolainen, Tero Ala-Kokko
      Abstract: The aim of the present study was to investigate whether expression of monocyte and lymphocyte surface molecules differs between patients with severe sepsis and non-septic patients treated in the intensive care unit (ICU). The expression of monocyte CD14, CD40, CD80 and HLA-DR, and lymphocyte CD69 were analyzed using quantitative flow cytometry on three consecutive days in 27 patients with severe sepsis and in 15 non-septic patients. Receiver operating characteristic analyses were performed and each corresponding area under the curve (AUC) was determined. The results showed that the expression levels of CD40 on monocytes and CD69 on CD4+ T cells and on natural killer (NK) cells were highest in patients with severe sepsis (p < 0.05). Monocyte CD40 and NK cell CD69 expression levels were higher in patients with severe sepsis and positive blood culture compared with those with negative blood culture (p < 0.05). The highest values of AUC for severe sepsis detection were 0.836 for CD40, 0.872 for CD69 on NK cells, and 0.795 for CD69 on CD4+ T cells. These findings suggest that monocyte CD40 and CD69 on NK cells and CD4+ T cells could prove useful for new approaches in the identification of severe sepsis in the ICU.
