  • IFN-γ against the 38-kDa antigen of Mycobacterium tuberculosis
           discriminates pulmonary tuberculosis from infection and infection from
           exposure: evidence from a study of human population in a high endemic
           setting
    • Authors: Fekadu Abebe; Mulugeta Belay, Mengistu Legesse
      Abstract: Mycobacterium tuberculosis (Mtb) 38-kDa antigen is an immunogenic lipoprotein that induces strong T-cell responses in experimental animals. However, there is limited information on the role of this antigen in human population. In this article, we present the dynamics of pro-inflammatory (IFN-γ and TNF-α) and anti-inflammatory cytokine (IL-10) against the 38 kDa in cohorts of pulmonary TB (PTB) patients, household contacts (HHCs), and community controls (CCs) in a high endemic setting. Whole blood assay was used to determine the levels of cytokines in 149 patients, 149 HHCs, and 68 CCs at baseline, 6 months, and 12 months. At baseline, the level of IFN-γ was significantly (p < 0.0001) higher in CCs and HHCs than in untreated patients. CCs had significantly (p < 0.05) higher level of IFN-γ than HHCs. There was no significant difference between treated and untreated patients, and there was no significant change in HHCs over 12 months. At baseline, the levels of IL-10 and TNF-α were significantly (p < 0.0001) higher in patients than in HHCs and CCs. No significant change was observed between treated patients and untreated patients and HHCs over time. The study shows that IFN-γ against the 38 kDa discriminates clinical TB from infection and infection from exposure, suggesting its potential for immune protection and diagnosis.

  • Macrolide and fluoroquinolone resistance in Mycoplasma genitalium in two
           Swedish counties, 2011–2015
    • Authors: Ronza Hadad; Daniel Golparian, Amaya C. Lagos, Johan Ljungberg, Peter Nilsson, Jörgen S. Jensen, Hans Fredlund, Magnus Unemo
      Abstract: Mycoplasma genitalium, causing non-gonococcal non-chlamydial urethritis and associated with cervicitis, has developed antimicrobial resistance (AMR) to both the macrolide azithromycin (first-line treatment) and the fluoroquinolone moxifloxacin (second-line treatment). Our aim was to estimate the prevalence of resistance, based on genetic AMR determinants, to these antimicrobials in the M. genitalium population in two Swedish counties, Örebro and Halland, 2011–2015. In total, 672 M. genitalium positive urogenital samples were sequenced for 23S rRNA and parC gene mutations associated with macrolide and fluoroquinolone resistance, respectively. Of the samples, 18.6% and 3.2% in Örebro and 15.2% and 2.7% in Halland contained mutations associated with macrolide and fluoroquinolone resistance, respectively. The predominating resistance-associated mutations in the 23S rRNA gene was A2059G (n = 39) in Örebro and A2058G (n = 13) and A2059G (n = 13) in Halland. The most prevalent possible resistance-associated ParC amino acid alterations were S83I (n = 4) in Örebro and S83N (n = 2) in Halland. Resistance-associated mutations to both macrolides and fluoroquinolones were found in 0.7% of samples. Our findings emphasize the need for routine AMR testing, at a minimum for macrolide resistance, of all M. genitalium-positive samples and regular national and international surveillance of AMR in M. genitalium, to ensure effective patient management and rational antimicrobial use.

  • Pseudomesotheliomatous carcinoma of the pleura: an autopsy case of
           metastasis from a G-CSF-producing anaplastic carcinoma of the pancreas
    • Authors: Yui Hattori; Kazuhiro Sentani, Takuya Hattori, Naohide Oue, Wataru Yasui
      Abstract: Pseudomesotheliomatous carcinoma is a malignant tumor that extends along the pleura mimicking malignant mesothelioma. An 81-year-old male patient presented to our hospital with epigastralgia, and abdominal computed tomography (CT) showed a 36-mm tumor in the pancreatic tail. The laboratory data revealed a high leukocyte count (>44 000/μL). Chest CT showed left pleural thickening with pleural effusion. The cancer showed a poor response to chemotherapy, and the patient died of respiratory failure at 5 months after the onset of disease. Autopsy showed solid tumor with hemorrhage, measuring 6 cm in diameter, in the pancreatic tail, with wide invasion to the stomach, left adrenal gland, spleen, and diaphragm. The left pleura, which was circumferentially thickened by the involved tumor, macroscopically resembled pleural mesothelioma. Histologically, the primary pancreatic tumor was diagnosed as anaplastic carcinoma, due to the absence of glandular structures or other features that would indicate a definite direction of differentiation. The primary lesion and carcinoma involving the left pleura were all positive for G-CSF. We recently experienced an autopsy case of G-CSF-producing anaplastic carcinoma with pseudomesotheliomatous spread.

  • The genetically determined production of the alarmin eosinophil-derived
           neurotoxin is reduced in visceral leishmaniasis
    • Authors: Kristin Blom; Amir I. Elshafie, Ulla-Britt Jönsson, Johan Rönnelid, Lena Douhan Håkansson, Per Venge
      Abstract: Visceral leishmaniasis (VL) is the most severe form of leishmaniasis. Recent findings indicate that dendritic cells have a key role in the defense against the Leishmania parasite and that the activity of this cell may be modified by the eosinophil secretory protein eosinophil-derived neurotoxin (EDN). We hypothesized that the interactions between dendritic cells and EDN might be of importance in the disease development. Cellular content of EDN was analyzed by ELISA. The single-nucleotide polymorphisms at positions 405, 416, and 1122 in the EDN gene were analyzed by real-time PCR with TaqMan® reagents. The study cohorts comprised 239 Sudanese subjects (65 healthy controls and 174 with VL) and 300 healthy Swedish controls. The eosinophil content of EDN was lower in VL as compared with controls (p < 0.0001). The EDN405 (G>C) genotype distribution was similar among Swedish and Sudanese controls, whereas VL subjects had a higher prevalence of the EDN405-GG genotype (p < 0.0001). The content of EDN in the eosinophils was closely linked to the EDN405 polymorphism (p = 0.0002). Our findings suggest that the predisposition to acquire VL is related to the genetic polymorphism of the EDN gene and the reduced production by the eosinophil of this gene product.

  • Erysipelothrix rhusiopathiae serotype 5-associated metritis in a Norwegian
           Red heifer
    • Authors: Øyvor Kolbjørnsen; Bjarne Bergsjø, Jeanette Sveen, Tanja Opriessnig
      Abstract: This report summarized the findings of a case of Erysipelothrix rhusiopathiae infection in a farmed Norwegian Red heifer located in the south-east of Norway. The 2.5-year-old pregnant heifer was found dead after a short episode of inappetence. On gross exam, the heifer was severely dehydrated with uterine torsion. Microscopically, necrosis of the endometrium was present throughout the uterus along with presence of intralesional Gram-positive bacteria, interstitial nephritis, and pyelonephritis. E. rhusiopathiae was isolated from the uterus and placenta and was also demonstrated by immunohistochemistry (IHC) in the uterus, placenta, and kidney. The E. rhusiopathiae isolate was further characterized as serotype 5. To the authors’ knowledge, this is the first report of bacterial metritis associated with E. rhusiopathiae serotype 5 infection. The etiology of the infection is unknown but the E. rhusiopathiae could have been a primary or opportunistic pathogen. Serotype 5 of E. rhusiopathiae has been identified in several mammalian species in recent years and could be emerging.

  • Relationship between hepatic progenitor cells and stellate cells in
           chronic hepatitis C genotype 4
    • Authors: Thanaa El Sayed Ahmed Helal; Nermine Ahmed Ehsan, Nehal Ahmed Radwan, Eman Abdelsameea
      Abstract: Hepatitis C virus (HCV) infection represents a major health problem in many areas of the world, especially Egypt. Hepatic progenitor cells (HPCs) and hepatic stellate cells (HSCs) have been implicated in fibrosis progression in chronic HCV. The aim of this study was to investigate the role of HPCs and HSCs in chronic HCV infection and the relationship between both cell types. This retrospective study was conducted on 100 chronic HCV patients. Immunohistochemistry was performed on liver tissue sections for cytokeratin 19 (progenitor cell markers), smooth muscle actin (stellate cell markers), matrix metalloproteinase-9 (MMP-9), and transforming growth factor beta (TGF-ß). The necroinflammatory activity was significantly related to the number of isolated HPCs and TGF-ß expression (p = 0.003 and p = 0.001 respectively). Advanced stages of fibrosis showed significantly increase number of HPCs (p = 0.001), higher ratio of HSCs (p = 0.004), more expression of TGF-ß (p = 0.001) and MMP-9 (p = 0.001). There was a significant direct correlation between immunoexpression of HPCs and HSCs for isolated cells (r = 0.569, p = 0.001) and ductular reaction (r = 0.519, p = 0.001). Hepatic progenitor cells and stellate cells play a significant role in the development and progression of fibrosis in chronic HCV. More interestingly, the significant direct correlation between HPCs and HSCs suggests a synergistic interrelation.

  • Localization of surfactant protein-D in the rheumatoid synovial membrane
    • Authors: Anne Friesgaard Christensen; Grith Lykke Sorensen, Kirsten Junker, Peter Hvidbak Revald, Claus Varnum, Flemming Brandt Sorensen, Peter Junker
      Abstract: Surfactant protein-D (SP-D) is a collectin, which plays an important role in airway protection and inflammation. The molecule has both pro- and anti-inflammatory capacities depending on its molecular size. Its involvement in joint diseases is largely unknown and the aim of this investigation was to study SP-D occurrence and distribution in the synovial membrane of patients with long-standing rheumatoid arthritis (RA) and osteoarthritis (OA). Six RA patients and six OA patients, who underwent total hip arthroplasty, were included in the study. Synovial tissue biopsies were obtained during surgery and subsequently prepared for immunohistochemistry. In this first, small-scale comparative study on the occurrence of SP-D in the synovial membrane of RA and OA, we report that SP-D was only present in the microvascular endothelium in subsynovial and pannus tissue and that the immunostaining was much stronger than in OA. This distribution pattern suggests that SP-D modulates RA inflammatory activities.

  • Napsin A and WT 1 are useful immunohistochemical markers for
           differentiating clear cell carcinoma ovary from high-grade serous
           carcinoma
    • Authors: Bharat Rekhi; Kedar K. Deodhar, Santosh Menon, Amita Maheshwari, Jyoti Bajpai, Jaya Ghosh, Surappa Thumkur Shylasree, Sudeep Gupta
      Abstract: Clear cell carcinoma (CCC) of the ovary is an uncommon, but an aggressive epithelial ovarian cancer (EOC), which has overlapping histopathologic features with other ovarian tumours. Lately, Napsin A has been identified as its useful diagnostic immunohistochemical (IHC) marker. Fifty-eight prospectively diagnosed ovarian CCCs, 53 high-grade serous carcinomas (HGSCs), 16 endometrioid adenocarcinomas (EMACs), six mixed carcinomas, containing components of CCC and EMAC, seven metastatic mucinous adenocarcinomas and six ovarian yolk sac tumours (YSTs) were tested for Napsin A immunostaining. Fifty ovarian CCCs, 50 HGSCs, seven ovarian EMACs and five mixed carcinomas were tested for WT1 immunostaining. Napsin A was positively expressed in all 58 (100%) CCCs; was focally positive in 1 of 6 YSTs; in 1/16 EMACs and in six cases of mixed carcinomas, while it was negative in all 53 HGSCs and in seven metastatic mucinous adenocarcinomas. Other IHC markers expressed in cases of CCC ovary were CK7 (31/31) (100%), WT1 (0/50), p53 (20/26, ‘wild type’), ER (4/31, focal) (12.9%), PAX8 (14/14) (100%), glypican-3 (4/10, focal) (44.4%), p16INK4 (5/5, focal) and CK20 (0/5). Various IHC markers expressed in HGSCs were WT1 (48/50) (96%), p53 (31/31, mostly ‘mutation type’), CK7 (9/9) (100%) ER (13/16, variable) (81.2%) and PAX8 (14/14) (100%). IHC markers expressed in EMACs were ER (15/16) (93.7%), CK7 (2/2) (100%) and WT1 (0/7). IHC markers expressed in mixed carcinomas were CK7 (2/2) (100%), WT1 (0/2), focal Napsin A (6/6) and focal ER (5/6). The sensitivity and specificity of Napsin A for the diagnosis of CCC ovary was 100% and 90.9%, respectively. The sensitivity and specificity of WT1 for diagnosis of HGSC ovary was found to be 96% and 100%, respectively. Napsin A and WT1 are highly sensitive and specific IHC markers for diagnosing ovarian CCCs and HGSCs, respectively, and in differentiating these tumours from their mimics. Napsin A is useful in identification of component of CCC in certain EMACs.

  • In vitro activity and time-kill curve analysis of sitafloxacin against a

           gonorrhoeae isolates
    • Authors: Agnez Jönsson; Sunniva Foerster, Daniel Golparian, Ryoichi Hamasuna, Susanne Jacobsson, Magnus Lindberg, Jörgen Skov Jensen, Makoto Ohnishi, Magnus Unemo
      Abstract: Treatment of gonorrhoea is a challenge worldwide because of emergence of resistance in N. gonorrhoeae to all therapeutic antimicrobials available and novel antimicrobials are imperative. The newer-generation fluoroquinolone sitafloxacin, mostly used for respiratory tract infections in Japan, can have a high in vitro activity against gonococci. However, only a limited number of recent antimicrobial-resistant isolates from Japan have been examined. We investigated the sitafloxacin activity against a global gonococcal panel (250 isolates cultured in 1991–2013), including multidrug-resistant geographically, temporally and genetically diverse isolates, and performed time-kill curve analysis for sitafloxacin. The susceptibility to sitafloxacin (agar dilution) and seven additional therapeutic antimicrobials (Etest) was determined. Sitafloxacin was rapidly bactericidal, and the MIC range, MIC50 and MIC90 was ≤0.001–1, 0.125 and 0.25 mg/L, respectively. There was a high correlation between the MICs of sitafloxacin and ciprofloxacin; however, the MIC50 and MIC90 of sitafloxacin were 6-fold and>6-fold lower, respectively. Sitafloxacin might be an option for particularly dual antimicrobial therapy of gonorrhoea and for cases with ceftriaxone resistance or allergy. However, further in vitro and particularly in vivo evaluations of potential resistance, pharmacokinetics/pharmacodynamics and ideal dosing for gonorrhoea, as well as performance of randomized controlled clinical, trials are crucial.

  • Transmission electron microscopy helpfulness in Whipple's disease masked
           by immunosuppressant therapy for arthritis
    • Authors: Alessandra Loiodice; Giuseppe Losurdo, Andrea Iannone, Roberta Rossi, Maria Grazia Fiore, Domenico Piscitelli
      Abstract: A 61-year-old woman received a diagnosis of undifferentiated non-erosive arthritis in 2010 and assumed methotrexate and steroids in 2014. After 1 year, she experienced watery diarrhea, vomiting, fever, weight loss, and severe hypoalbuminemia, thus being admitted into our Unit. Esophagogastroduodenoscopy showed duodenal lymphangiectasia and duodenal biopsy samples several foamy PAS-positive macrophages and villous subtotal atrophy. Transmission electron microscope demonstrated several extracellular and intracellular rod-shaped bacteria (Tropheryma whipplei). Therefore, we diagnosed Whipple's disease. Our patient assumed doxycycline/hydroxychloroquine with prompt remission of gastrointestinal symptoms. At 1 year of follow-up, she was symptom-free, histological reassessment showed almost complete mucosal healing and transmission electron microscope demonstrated bacteria breaking/disappearance. The present report demonstrates that: (i) rheumatological manifestations are common onset symptoms of Whipple's disease; (ii) immunosuppressive therapy may delay the diagnosis and worsen clinical presentation; (iii) transmission electron microscopy for specific bacteria detection/disappearance is an helpful diagnostic tool, when available.

  • Impact of heat shock protein 60KD in combination with outer membrane
           proteins on immune response against Brucella melitensis
    • Authors: Tooba Abbassi-Daloii; Soheil Yousefi, Mohammad Hadi Sekhavati, Mojtaba Tahmoorespur
      Abstract: Brucellosis caused by the bacterium Brucella affects various domestic and wild species. The outer membrane proteins 25 and 31 play key roles on stimulation of cell-mediated immune response against Brucella. GroEL as one of the major Brucella antigens stimulates the immune system and increases intracellular survival of bacteria. In the present study, we assumed injection of GroEL in combination with OMP25 and OMP31 would offer higher immunity levels. So, the impact of GroEL with different concentrations of recombinant outer membrane proteins emulsified in Chitosan Nanoparticles on immune responses was evaluated in mice model. Results showed both univalent (except rGroEL) and divalent immunized groups induced higher IFN-γ, TNF-α, and IL-4 titers in comparison to negative control groups. While GroEL showed negative effect on TNF-α titer, there were positive increase trends in IFN-γ in some treatments. Analysis of humoral antibody response revealed both univalent and divalent immunized groups induced higher IgG2a titer than IgG1 titer, indicating strong bent of Th1 immune response. Also, results showed GroEL can have positive impact on lymphocyte proliferation response. Overall, mice immunization using individual OMP25 or OMP31 demonstrated more effective cell-mediated immunity, although some combinations of rGroEL and rOMP31 vaccines were more efficient than other divalent ones.

    • Authors: Denİz Sertel Şelale; Meltem Uzun
      Abstract: Inexpensive, rapid, and reliable tests for detecting the presence and drug susceptibility of Mycobacterium tuberculosis complex (MTBC) are urgently needed to control the transmission of tuberculosis. In this study, we aimed to assess the accuracy and speed of the microscopic-observation drug susceptibility (MODS) assay in the identification of MTBC and detection of multidrug resistance. Sputum samples from patients suspected to have tuberculosis were simultaneously tested with MODS and conventional culture [Löwenstein-Jensen (LJ) culture, BACTEC MGIT™ 960 (MGIT) system], and drug susceptibility testing (MGIT system) methods. A total of 331 sputum samples were analyzed. Sensitivity and specificity of MODS assay for detection of MTBC strains were 96% and 98.8%, respectively. MODS assay detected multidrug resistant MTBC isolates with 92.3% sensitivity and 96.6% specificity. Median time to culture positivity was similar for MGIT (8 days) and MODS culture (8 days), but was significantly longer with LJ culture (20 days) (p

  • Fibrin thrombi in deceased donor kidneys: Prevalence and influence on
           graft function and graft survival in transplanted patients
    • Authors: Ditte Hansen; Sara Rørvig, Claus B. Andersen, Søren S. Sørensen
      Abstract: Fibrin thrombi (FT) are occasionally found in the pre-implantation biopsy of kidneys from deceased donors. The aim of this study was to monitor the prevalence and answer the question whether FT has any impact on future graft function in a Danish patient cohort. We looked for FT in all donor kidney biopsies taken at the time of renal transplantation in a Danish transplantation unit during a 10-year period. Every recipient transplanted with a FT donor kidney (n = 15) were matched with up to five control recipients (n = 69), and graft function and graft survival were assessed. FT was present in 3% of the transplanted donor kidneys. Graft function was reduced in the FT group 6 months after transplantation (median estimated glomerular filtration rate (eGFR): 29 mL/min vs 46 mL/min; p = 0.017), but at 12 months, an apparent difference did not reach statistical significance. More patients were on dialysis in the FT group after 12 months compared with the control group (27% vs 6%; p = 0.049). In conclusion, FT in donor kidney biopsies at time of transplantation is a risk factor for the development of reduced renal function during the first year of transplantation.

  • Association of Helicobacter pylori infection with Toll-like receptor-4
           Thr399Ile polymorphism increased the risk of peptic ulcer development in
           North of Iran
    • Authors: Mehdi Tourani; Maryam Habibzadeh, Javad Shokri-Shirvani, Omid Teymournejad, Amrollah Mostafazadeh, Soraya Khafri, Hamid Reza Nouri
      Abstract: Toll-like receptor-4 (TLR4) polymorphisms may influence host immune response against Helicobacter pylori (H. pylori). This study aimed to investigate whether TLR4 polymorphisms are associated with H. pylori susceptibility and risk of peptic ulcer development or not. The TLR4 + 3725 G/C polymorphism was studied using polymerase chain reaction with confronting two-pair primers (PCR–CTPP). In addition, TLR4 Asp299Gly and Thr399Ile polymorphisms were evaluated by PCR-restriction fragment length polymorphism (RFLP). There was no significant difference in TLR4 + 3725 G/C and Asp299Gly genotype frequencies between non-peptic ulcer (NPUD) and peptic ulcer (PUD) individuals in the context of peptic ulcer development and susceptibility to infection with H. pylori. Nevertheless, a significant association with increased risk for PUD development was observed for polymorphism TLR4 Thr399Ile [odds ratio (OR) = 4.2; 95% confidence interval (CI) = 1.35–13.26; p = 0.01]. Correspondingly, TLR4 Thr399Ile polymorphism was associated with H. pylori susceptibility (OR = 0.27; 95% CI = 0.08–0.88; p = 0.04). In addition, TLR4 Thr399Ile polymorphism increased 4.2-fold, the risk of peptic ulcer development in individuals infected by H. pylori carrying CT + TT genotype. Our results showed that TLR4 Thr399Ile polymorphism along with H. pylori infection may play critical roles in peptic ulcer development in North of Iran.

    • Authors: Danny L. G. Fagundes; Eduardo L. França, Michelangelo B. Gonzatti, Marilza V. C. Rugde, Iracema M. P. Calderon, Adenilda C. Honorio-França
      Abstract: The study investigated the role of cytokines IL-4 and IL-17 in the modulation of the functional activity of mononuclear phagocytes in diabetic pregnant women with hyperglycemia. Sixty pregnant women were assigned to the following groups: nondiabetic (ND), mild gestational hyperglycemia (MGH), gestational diabetes mellitus (GDM), or type 2 diabetes mellitus (DM2). The functional activity of phagocytes from maternal blood, cord blood, and colostrum was assessed by determining their superoxide release, phagocytosis, microbicidal activity, and intracellular Ca2+ release. Irrespective of glycemic status, colostrum and blood cells treated with IL-4 and IL-17 increased superoxide release in the presence of enteropathogenic Escherichia coli (EPEC). The highest phagocytosis rate was observed in cells from the DM2 group treated with IL-4. In all the groups, phagocytes from colostrum, maternal blood, and cord blood exhibited higher microbicidal activity against EPEC when treated with cytokines. IL-17 increased intracellular Ca2+ release by colostrum phagocytes in diabetic groups. The results indicate that the IL-4 and IL-17 modulate the functional activity of phagocytes in the maternal blood, cord blood, and colostrum of diabetic mother. The natural immunity resulting from the interaction between the cells and cytokines tested may be an alternative procedure to improve the prognosis of maternal and newborn infections.

      Abstract: The study evaluated primary antibiotic resistance of Helicobacter pylori within the period 2013–2015 and trends of antibiotic consumption over the last decade in Lithuania; 242 adults and 55 children were included in the study. E-tests were performed for amoxicillin, metronidazole, clarithromycin, ciprofloxacin, rifampicin and tetracycline. The presence of H. pylori and clarithromycin resistance was additionally tested by PCR. Helicobacter pylori culture was positive in 67 of 242 (28%) adult and in 12 of 55 (21.8%) children samples. Resistance rates among adults by E-tests were as follows: metronidazole – 32.8% (95% confidence interval (CI): 22.7–44.7%), ciprofloxacin – 7.5% (95% CI: 3.2–16.3%), rifampicin – 7.5% (95% CI: 3.2–16.3%), amoxicillin – 0%, whereas resistance rates in children were as follows: metronidazole – 25% (95% CI: 8.9–53.2%), rifampicin – 8.3% (CI: 1.5–35.4%), amoxicillin and ciprofloxacin – 0%. Accumulated clarithromycin resistance rates by E-tests and PCR were 8.2% (95% CI: 4.1–16.0%) in adults and 17.7% (95% CI: 6.2–41.0%) in children. Total use of macrolides and lincosamides in Lithuania increased from 1.26 to 1.86 defined daily dose (DDD)/1000 inhabitants/day among adults, while it has doubled from 1.10 to 2.22 DDD/1000/children/day in children within 2003–2015. There are no significant changes in the susceptibility of H. pylori to the most widely used antibiotics in adults over the last years in Lithuania; however, clarithromycin resistance among children exceeds 15% and mandates further larger-scale studies in paediatric population.

      Abstract: Vascular invasion (VI) is a well-established marker for lymph node metastasis and outcome in endometrial cancer. Our study explored whether specific types of VI, defined as lymphatic (LVI) or blood vessel invasion (BVI), predict pattern of metastasis. From a prospectively collected cohort, we conducted a case–control study by selecting three groups of endometrial cancer patients (n = 183): 52 with positive lymph nodes at primary surgery, 33 with negative nodes at primary surgery and later recurrence and death from disease, and 98 with negative nodes and no recurrence. All patients underwent hysterectomy with lymphadenectomy. Immunohistochemical staining with D2-40 and CD31 antibodies was used to differentiate between BVI and LVI. By immunohistochemical staining, detection of VI increased from 24.6 to 36.1% of the cases. LVSI was significantly more often seen in patients with positive lymph nodes compared with patients with negative nodes (p = 0.001). BVI was significantly more often seen in node-negative patients with recurrence compared with node-negative patients without recurrence (p = 0.011). In multivariable analysis, BVI, age, and tumor grade were predictors separating patients with and without recurrence. Lymph node–positive patients showed more often LVI compared with lymph node–negative patients, while BVI seems to be a predictor for recurrent disease.

  • Cancer/testis antigen SPATA19 is frequently expressed in benign prostatic
           hyperplasia and prostate cancer
    • Authors: Kah Keng Wong; Faezahtul Arbaeyah Hussain, Suet Kee Loo, José I. López
      Abstract: Spermatogenesis-associated 19 (SPATA19) is a cancer/testis antigen overexpressed in various cancers. However, its protein expression profile in malignant or non-malignant tissues remains unknown. Thus, in this study, we investigated SPATA19 protein expression patterns in a panel of non-malignant human samples and primary prostate cancer (PCa) with or without benign prostatic hyperplasia (BPH) tissues. SPATA19 was absent in all non-malignant tissues investigated (n=14) except testis and prostate tissues. In terms of malignancies, all PCa cases were positive for SPATA19 exhibiting frequency between 20 and 100% (median 85%) with 63 (52.5%) and 57 (47.5%) cases demonstrating weak/moderate and strong intensities, respectively. Thirty-nine PCa cases (32.5%) contained BPH, and all BPH glands were SPATA19 positive (frequency between 20 and 100%; median 90%) with 13 (33.3%) demonstrating strong SPATA19 expression. Higher SPATA19 expression (higher frequency, intensity, or H-score) was not associated with overall survival or disease-specific survival (DFS) in all PCa cases. However, biochemical recurrence (BR) was associated with worse DFS (p = 0.005) in this cohort of 120 patients, and cases with strong SPATA19 intensity were associated with BR (p = 0.020). In conclusion, we showed that SPATA19 protein was frequently expressed in both BPH and PCa glands, and this warrants future investigations on its pathogenic roles in the disease.

      Abstract: The aim of this study is to establish heat shock protein 110 (HSP110) as a prognostic biomarker of colorectal carcinomas (CRCs) with microsatellite instability-high (MSI-H) by considering the intratumoral heterogeneity of HSP110 expression. We performed whole-section immunohistochemistry (IHC) for wild-type HSP110 (HSP110wt) in 164 MSI-H CRCs. The intensity of the HSP110wt expression in tumor cells was semiquantitatively scored (0/1/2/3), and the HSP110wt expression status of each tumor was classified as low or high using the following four scoring criteria: H-score, dominant intensity score, lowest intensity score, and highest intensity score. Among the four criteria, only the dominant intensity score-based dichotomous classification of HSP110wt expression was significantly associated with a difference in disease-free survival (log-rank p = 0.035) in 164 MSI-H CRCs. The HSP110wt-low MSI-H CRCs were significantly correlated with larger deletions in the HSP110 T17 mononucleotide repeat (≥4 bp; p

  • M2 polarization of monocytes in ankylosing spondylitis and relationship
           with inflammation and structural damage
    • Authors: Jinzhu Zhao; Wei Yuan, Chunsheng Tao, Peifeng Sun, Zaixing Yang, Weidong Xu
      Abstract: The aim of this study was to evaluate the polarization of peripheral blood monocytes in the patients with ankylosing spondylitis (AS) and to determine the correlations between monocyte polarization and inflammation and structural damage. A total of 120 AS patients, 50 rheumatoid arthritis (RA) patients and 100 healthy controls were enrolled in the study. M1 (CD68+CD192+) and M2 (CX3CR1+CD163+) monocytes were characterized by flow cytometry. Demographic, clinical, radiographic and laboratory data were collected and analyzed. A large increase in M2 (CX3CR1+CD163+) monocytes was observed in AS, and M2/M1 ratio was 7.18 ± 6.12, 2.54 ± 3.14 and 35.61 ± 20.04 in control, RA and AS, respectively. The M2/M1 ratio correlated with modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) (r = 0.565; p

  • Epidemiological characterization of a nosocomial outbreak of extended
           spectrum β-lactamase Escherichia coli ST-131 confirms the clinical value
           of core genome multilocus sequence typing
    • Authors: Hanna Woksepp; Anna Ryberg, Linda Berglind, Thomas Schön, Jan Söderman
      Abstract: Enhanced precision of epidemiological typing in clinically suspected nosocomial outbreaks is crucial. Our aim was to investigate whether single nucleotide polymorphism (SNP) analysis and core genome (cg) multilocus sequence typing (MLST) of whole genome sequencing (WGS) data would more reliably identify a nosocomial outbreak, compared to earlier molecular typing methods. Sixteen isolates from a nosocomial outbreak of ESBL E. coli ST-131 in southeastern Sweden and three control strains were subjected to WGS. Sequences were explored by SNP analysis and cgMLST. cgMLST clearly differentiated between the outbreak isolates and the control isolates (>1400 differences). All clinically identified outbreak isolates showed close clustering (≥2 allele differences), except for two isolates (>50 allele differences). These data confirmed that the isolates with>50 differing genes did not belong to the nosocomial outbreak. The number of SNPs within the outbreak was ≤7, whereas the two discrepant isolates had>700 SNPs. Two of the ESBL E. coli ST-131 isolates did not belong to the clinically identified outbreak. Our results illustrate the power of WGS in terms of resolution, which may avoid overestimation of patients belonging to outbreaks as judged from epidemiological data and previously employed molecular methods with lower discriminatory ability.

  • Angiogenesis in Schistosoma haematobium-associated urinary bladder cancer
    • Authors: Anderson Dematei; Rúben Fernandes, Raquel Soares, Helena Alves, Joachim Richter, Monica C. Botelho
      Abstract: Schistosoma haematobium, a parasitic flatworm that infects more than 100 million people, mostly in the developing world, is the causative agent of urogenital schistosomiasis, and is associated with a high incidence of squamous cell carcinoma (SCC) of the bladder. During infection, eggs are deposited in the bladder causing an intense inflammatory reaction. Angiogenesis is defined as the formation of new blood vessels from preexisting ones and is recognized as a key event in cell proliferation and carcinogenesis and spread of malignant lesions. A growing amount of evidence points to angiogenesis playing a key role in schistosomiasis-associated bladder cancer. Thus, identifying biomarkers of this process plays an important role in the study of cancer. Here, we review recent findings on the role of angiogenesis in bladder cancer and the growth factors that induce and assist in their development, particularly SCC of the bladder associated to urogenital schistosomiasis.

  • Expression of CD markers' in immune thrombocytopenic purpura: prognostic
           approaches
    • Authors: Masumeh Maleki Behzad; Ali Amin Asnafi, Kaveh Jaseb, Mohammad Ali Jalali Far, Najmaldin Saki
      Abstract: Immune Thrombocytopenic Purpura (ITP) is a common autoimmune bleeding disorder characterized by a reduction in peripheral blood platelet counts. In this disease, autoantibodies (Auto-Abs) are produced against platelet GPIIb/GPIIIa by B cells, which require interaction with T cells. In this review, the importance of B and T lymphocytes in ITP prognosis has been studied. Relevant literature was identified by a PubMed search (1990–2016) of English-language papers using the terms B and T lymphocyte, platelet, CD markers and immune thrombocytopenic purpura. T and B lymphocytes are the main immune cells in the body. Defective function causes disrupted balance of different subgroups of lymphocytes, and abnormal expression of surface markers of these cells results in self-tolerance dysfunction, as well as induction of Auto-Abs against platelet glycoproteins (PG). Given the role of B and T cells in production of autoantibodies against PG, it can be stated that the detection of changes in CD markers' expression in these cells can be a good approach for assessing prognosis in ITP patients.

  • Effects of FCGRIIIa-158V/F polymorphism on antibody-dependent cellular
           cytotoxicity activity of adalimumab
    • Authors: Koji Kimura; Daigo Kobayashi, Saori Hatoyama, Mizuki Yamamoto, Risa Takayanagi, Yasuhiko Yamada
      Abstract: The associations between the efficacy of IgG reagents and the FCGRIIIa-158V/F polymorphism (rs396991) have been investigated. Although the genotype frequencies in healthy Japanese have been reported, those have varied, as one study reported that the proportions of V/V, V/F, and F/F were 59.1%, 38.6%, and 2.3%, respectively, while another study found that they were 4%, 44%, and 52%, respectively. However, there are no known investigations of the association between the antibody-dependent cellular cytotoxicity (ADCC) activity of adalimumab (ADA), an IgG reagent, in combination with FcγRIIIa and the polymorphism. In this study, we analyzed healthy Japanese to clarify genotype frequency using a direct sequence method. In addition, we examined the association between the ADA-mediated ADCC activity and the polymorphism. Our results showed that the frequencies of the V/V, V/F, and F/F genotypes in healthy Japanese were 9.2%, 39.8%, and 51.0%, respectively. The average activity of ADA-mediated ADCC was 25.0%, 19.0%, and 13.3% in the V/V, V/F, and F/F genotypes, respectively. Then, the ADCC activity of V/V was significantly higher than that of F/F (p < 0.05) in therapeutic concentration. The differences in therapeutic effect of ADA among individuals can be explained, in part, by ADCC activity via the FCGRIIIa-158V/F polymorphism.

  • Loss of regulatory characteristics in CD4+CD25+/hi T cells induced by
           impaired transforming growth factor beta secretion in pneumoconiosis
    • Authors: Lu-Qin Bian; Ling Mao, Ying Bi, Shao-Wei Zhou, Zi-Dan Chen, Jun Wen, Jin Shi, Ling Wang
      Abstract: Pneumoconiosis is caused by the accumulation of airborne dust in the lung, which stimulates a progressive inflammatory response that ultimately results in lung fibrosis and respiratory failure. It is possible that regulatory cells in the immune system could function to suppress inflammation and possibly slow or reverse disease progression. However, results in this study suggest that in pneumoconiosis patients, the regulatory T cells (Tregs) and B cells are functionally impaired. First, we found that pneumoconiosis patients presented an upregulation of CD4+CD25+ T cells compared to controls, whereas the CD4+CD25+ and CD4+CD25hi T cells were enriched with Th1- and Th17-like cells but not Foxp3-expressing Treg cells and evidenced by significantly higher T-bet, interferon (IFN)-γ, and interleukin (IL)-17 expression but lower Foxp3 and transforming growth factor (TGF)-β expression. Regarding the CD4+CD25hi T-cell subset, the frequency of this cell type in pneumoconiosis patients was significantly reduced compared to controls, together with a reduction in Foxp3 and TGF-β and an enrichment in T-bet, RORγt, IFN-γ, and IL-17. This skewing toward Th1 and Th17 types of inflammation could be driven by monocytes and B cells, since after depleting CD14+ monocytes and CD19+ B cells, the levels of IFN-γ and IL-17 were significantly decreased. Whole peripheral blood mononuclear cells and isolated monocytes and B cells in pneumoconiosis patients also presented reduced capacity of TGF-β secretion. Furthermore, monocytes and B cells from pneumoconiosis patients presented reduced capacity in inducing Foxp3 upregulation, a function that could be rescued by exogenous TGF-β. Together, these data indicated a potential pathway for the progression of pneumoconiosis through a loss of Foxp3+ Treg cells associated with impaired TGF-β secretion.

  • A role of human beta defensin-1 in predicting prostatic adenocarcinoma in
           cases of false-negative biopsy
    • Authors: Soon Auck Hong; Ki Hong Kim, Tae Jin Lee, Eon Sub Park, Mi Kyung Kim, Soon Chul Myung
      Abstract: The purpose of this study was to clarify the role of human beta defensin-1 (hBD-1) in predicting PAC in morphologically normal prostate glands. In total, 25 patients with a negative initial biopsy for PAC and diagnosed as PAC positive in subsequent biopsies performed within 1 year of the initial biopsy were included. As a control group, 22 patients negative for PAC in at least three consecutive histologic examinations were selected. Expression of hBD-1 was analyzed separately via immunohistochemistry in paired cores of non-neoplastic gland and PAC in the false-negative group and control group. Loss of hBD-1 expression was observed in 95.6% and 90.0% PAC cases with Gleason Patterns 3 and 4 in repeat biopsies, respectively. hBD-1 loss of basal cells in 40 (85.1%) previous non-neoplastic biopsy cores in the false-negative group was observed, in contrast to preserved basal cell expression of hBD-1 in 64 (72.7%) biopsy cores in the control group (p = 0.001). Multivariate logistic regression analysis showed that hBD-1 basal cell loss (≥20% of prostatic glands in total cores) is an independent factor for predicting PAC (odds ratio: 4.739, confidence interval: 1.093–20.554, p = 0.038). hBD-1 loss of basal cells is a useful indicator to identify extremely high-risk patients with initially negative biopsy.
