  • Systemic quinolones and risk of retinal detachment III: a nested
           case–control study using a US electronic health records database

    • Free pre-print version: Loading...

      Abstract: Background Quinolones are popular antibiotics that are known for their potency, broad coverage, and reasonable safety. Concerns have been raised about a possible association between quinolones and retinal detachment (RD). Methods We conducted a nested case–control study using electronic health records (EHR) from the Health Facts® Database. The initial cohort included all patients who were admitted between 2000 and 2016, with no history of eye disease, and had a minimum medical history of one year. Eligible cases comprised inpatients who were first admitted with a primary diagnosis of RD between 2010 and 2015. Each eligible case was matched without replacement to five unique controls by sex, race, age, and period-at-risk. We used conditional logistic regression to calculate RD risk, adjusting for exposure to other medications, and major risk factors. Results We identified 772 cases and 3860 controls. Whereas our primary analysis of all subjects revealed no quinolone-associated RD risk, elevated but non-significant risks were noted in African Americans (ciprofloxacin and levofloxacin), those aged 56–70 years old (moxifloxacin), and women (ciprofloxacin). Conclusion Our study did not identify an elevated RD risk within 30 days following systemic administration of quinolone antibiotics. Suggestions of increased risk observed in some population subgroups warrant further investigation.

  • Hydrochlorothiazide use is associated with the risk of cutaneous and lip
           squamous cell carcinoma: A systematic review and meta-analysis

    • Free pre-print version: Loading...

      Abstract: Purpose The aim of this study is to investigate the association between hydrochlorothiazide (HCTZ) use and the risk of cutaneous and lip squamous cell carcinoma development. Methodology We performed a systematic review and meta-analysis of case–control studies. We searched the Cochrane Library, PubMed, Scopus, Web of Science and LILACS. This study was registered in PROSPERO under protocol CRD42019129710. The meta-analysis was performed using the software Stata (version 12.0). Results A total of 2181 published studies referring to the theme were identified, from which six were included in this systematic review. Men were more frequently affected by cutaneous and lip squamous cell carcinoma than women, with a 1.42:1 ratio. The mean age for cutaneous and lip squamous cell carcinoma development was 73.7 years. This meta-analysis demonstrated a chance of developing cutaneous and lip squamous cell carcinoma in any region of the body in hydrochlorothiazide users of 1.76-fold higher than in non-users. In addition, a risk factor of 1.80 higher (CI 95% = 1.71–1.89) of cutaneous squamous cell carcinoma in the head and neck region was observed in HCTZ users. Moreover, in the analysis of the dose used, the chance of developing squamous cell carcinoma was 3.37-fold lower when the concentration of HCTZ used was less than 50,000 mg. Conclusions Our results confirm the association between the use of hydrochlorothiazide and the cutaneous and lip squamous cell carcinoma development.

  • Influence of daily versus alternate-day dosing of vonoprazan on
           intragastric pH, serum gastrin, and the antiplatelet function of
           clopidogrel

    • Free pre-print version: Loading...

      Abstract: Background Vonoprazan, a potassium-competitive acid blocker, inhibits gastric acid secretion and attenuates the antiplatelet function of clopidogrel more potently than esomeprazole. We investigated whether alternate-day dosing of vonoprazan might avoid this interaction with clopidogrel while providing sufficient gastric acid inhibition. Methods Following 24 h of pH monitoring (control regimen), 12 healthy volunteers received three regimens (clopidogrel-only regimen: clopidogrel 75 mg daily [q.d.]; vonoprazan alternate-day regimen: vonoprazan 10 mg every other day [q.o.d.] + clopidogrel 75 mg q.d.; vonoprazan daily regimen: vonoprazan 10 mg q.d. + clopidogrel 75 mg q.d.) for 14 days in a randomized open-label crossover manner. Intragastric pH monitoring was performed for 24 h on day 13 in the clopidogrel-only and vonoprazan q.d. regimens and for 48 h on days 13 and 14 in the vonoprazan q.o.d. regimen. Serum gastrin and inhibition of platelet aggregation (IPA) were measured before the commencement of pH monitoring in each regimen. Results Twelve volunteers completed the study. Equivalent median IPA values in the q.o.d. and q.d. regimens were measured (21.8% and 25%, respectively) and were significantly lower than that with the clopidogrel-only regimen (40.8%). The median pH4 holding time ratio for the vonoprazan q.o.d. regimen (49.7%) was superior to that of the clopidogrel-only regimen (18.4%), but was significantly inferior to that of the vonoprazan q.d. regimen (77.0%; p < 0.01). Conclusion Alternate-day administration of vonoprazan could not prevent the interaction between vonoprazan and clopidogrel, and acid inhibition was inferior to that with vonoprazan daily administration. Alternate-day administration of vonoprazan thus appears to be of questionable clinical utility.

  • Different interventions for preventing postoperative catheter-related
           bladder discomfort: a systematic review and meta-analysis

    • Free pre-print version: Loading...

      Abstract: Objective Catheter-related bladder discomfort (CRBD) is a common complication of intraoperative urinary catheterization. Various studies have evaluated the efficacy of different interventions in postoperative CRBD. The present review was performed to assess the efficacy of these interventions. Methods PubMed, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases were systematically searched to identify randomized controlled trials (RCTs) investigating the efficacy of different drugs for the prevention of postoperative CRBD. This review evaluated the incidence and severity of CRBD after different interventions at 0, 1, 2, and 6 h postoperatively. Results Forty-five studies including 31 different drugs were analyzed. Eleven drugs were investigated in more than two RCTs, of which dexmedetomidine, gabapentin, tolterodine, tramadol, ketamine, nefopam, oxybutynin, pregabalin, and pudendal nerve block (PNB) generally showed significantly higher efficacy than controls postoperatively. Solifenacin only showed significant efficacy compared with the control at 0 h, and intravenous lidocaine only showed significant efficacy compared with the control at 6 h. There were insufficient trials to draw conclusions regarding atropine, butylscopolamine, chlorpheniramine, clonidine, darifenacin, diphenhydramine, glycopyrrolate, intravesical bupivacaine, ketamine-haloperidol, pethidine-haloperidol, ketorolac, lidocaine-prilocaine cream, magnesium, hyoscine n-butyl bromide, oxycodone, paracetamol, parecoxib, trospium, resiniferatoxin, or amikacin. However, all but pethidine-haloperidol and chlorpheniramine showed some efficacy at various time points compared with controls. Conclusion This review suggests that dexmedetomidine, gabapentin, tolterodine, tramadol, ketamine, nefopam, oxybutynin, pregabalin, and PNB are effective in preventing postoperative CRBD. Considering the efficacy and adverse effects of all drugs, dexmedetomidine and gabapentin were ranked best.

  • Desmopressin therapy in children and adults: pharmacological
           considerations and clinical implications

    • Free pre-print version: Loading...

      Abstract: Purpose This review aims to provide prescribing clinicians a deeper appreciation of desmopressin’s clinical indications and formulation types, to better balance efficacy and safety through proper formulation selection. Background Since its discovery 50 years ago, desmopressin’s antidiuretic properties have been used for central diabetes insipidus, primary monosymptomatic nocturnal enuresis and adult nocturnal polyuria, while its coagulant effects are useful for mild hemophilia A and von Willebrand Disease. During this time, newer formulations of desmopressin have also been introduced to the market raising questions on interchangeability, dose conversion and safety. The wide array of clinical indications and variable pharmacokinetic properties of different desmopressin preparations raises the possibility of medication error, especially the risk of hyponatraemia. Methodology A narrative review to explore clinically relevant aspects of desmopressin therapy, synthesising information obtained from searches of published literature. Results We identified that the risk factors for developing hyponatremia include extremes of age, existing comorbidity, drug interaction, intranasal formulations and intercurrent illness. We describe the dose equivalence between all formulations to facilitate conversion. We highlight that in view of inter-subject variability, close monitoring is recommended when switching preparations. We found that paediatric data remains limited, leading to recent proposals for age- and weight-based dosing regimens. Conclusion The risk of hyponatremia, albeit small, can be reduced by adhering to the indication-specific doses and taking steps to govern the safe prescription of the drug. Further paediatric clinical trials are awaited to expand the evidence base of childhood desmopressin therapy.

  • Evaluation of CYP2C19 activity using microdosed oral omeprazole in humans

    • Free pre-print version: Loading...

      Abstract: Purpose To investigate the suitability of microdosed oral omeprazole for predicting CYP2C19 activity in vivo in combination with simultaneous assessment of CYP3A and CYP2D6 activity using both microdosed midazolam and yohimbine. Methods An open, fixed-sequence study was carried out in 20 healthy participants. Single microdosed (100 µg) and therapeutic (20 mg) doses of omeprazole were evaluated without comedication and after administration of established CYP2C19 perpetrators fluconazole (inhibition) and rifampicin (induction). To prevent degradation of the uncoated omeprazole microdose, sodium bicarbonate buffer was administered. The pharmacokinetics of omeprazole and its 5-hydroxy-metabolite were assessed as well as the pharmacokinetics of midazolam and yohimbine to estimate CYP3A4 and CYP2D6 activity. Results Calculated pharmacokinetic parameters after administration of 100 µg and 20 mg omeprazole in healthy subjects suggest dose proportionality. Omeprazole clearance was significantly decreased by fluconazole from 388 [95% CI: 266–565] to 47.2 [42.8–52.0] mL/min after 20 mg omeprazole and even further after 100 µg omeprazole (29.4 [24.5–35.1] mL/min). Rifampicin increased CYP2C19-mediated omeprazole metabolism. The omeprazole hydroxylation index was significantly related to omeprazole clearance for both doses. Both fluconazole and rifampicin altered CYP3A4 activity whereas no change of CYP2D6 activity was observed at all. Conclusions Microdosed oral omeprazole is suitable to determine CYP2C19 activity, also during enzyme inhibition and induction. However, the administration of sodium bicarbonate buffer also had a small influence on all victim drugs used. Trial registration EudraCT: 2017–004270-34.

  • Pharmacokinetics of mycophenolic acid and external evaluation of two
           limited sampling strategies of drug exposure in patients with juvenile
           systematic lupus erythematosus

    • Free pre-print version: Loading...

      Abstract: Introduction Mycophenolate mofetil (MMF), a pro-drug of mycophenolic acid (MPA), has become a major therapeutic option in juvenile systemic lupus erythematosus (jSLE). Monitoring MPA exposure using area under curve (AUC) has proved its value to increase efficacy and safety in solid organ transplantation both in children and adults, but additional data are required in patients with autoimmune diseases. In order to facilitate MMF therapeutic drug monitoring (TDM) in children, Bayesian estimators (BE) of MPA AUC0–12 h using limited sampling strategies (LSS) have been developed. Our aim was to conduct an external validation of these LSS using rich pharmacokinetics and compare their predictive performance. Methods Pharmacokinetic blood samples were collected from jSLE treated by MMF and MPA plasma concentrations were determined using high-performance liquid chromatography system with ultraviolet detection (HPLC–UV). Individual AUC0–12 h at steady state was calculated using the trapezoid rule and compared with two LSS: (1) ISBA, a two-stage Bayesian approach developed for jSLE and (2) ADAPT, a non-linear mixed effects model with a parametric maximum likelihood approach developed with data from renal transplanted adults. Results We received 41 rich pediatric PK at steady state from jSLE and calculated individual AUC0–12 h. The external validation MPA AUC0–12 h was conducted by selecting the concentration–time points adapted to ISBA and ADAPT: (1) ISBA showed good accuracy (bias: − 0.8 mg h/L), (2) ADAPT resulted in a bias of 6.7 mg L/h. The corresponding relative root mean square prediction error (RSME) was 23% and 43% respectively. Conclusion According to our external validation of two LSS of drug exposure, the ISBA model is recommended for Bayesian estimation of MPA AUC0–12 h in jSLE. In the literature focusing on MMF TDM, an efficacy cut-off for MPA AUC0–12 h between 30 and 45 mg h/L is proposed in jSLE but this requires additional validation.

  • The association between the availability of over the counter codeine and
           the prevalence of non-medical use

    • Free pre-print version: Loading...

      Abstract: Purpose To investigate the prevalence of non-medical use (NMU) of codeine in Germany, Italy, Spain and the UK and whether availability of OTC codeine has any association with NMU of the drug. Methods Data collected in the online Survey of Non-Medical Use of Prescription Drugs, in surveys launched in the second half of 2018 from (Germany (n = 14,969), Italy, (n = 9974), Spain (n = 9912) and the UK (n = 9819) were analysed. For each survey, the estimated prevalence and 95% confidence interval (CI) of respondents reporting NMU of prescription and/or OTC codeine within the last 12 months were calculated and compared. Results The prevalence of last 12-month NMU in Spain was 12.6% (95% CI 11.7–13.6) for prescription codeine, 6.3% (5.6–7.0) for OTC codeine and 16.1% (15.1–17.3) for any codeine (prescription and/or OTC). The prevalence of last 12-month NMU in the UK was 5.4% (4.9–5.8) for prescription codeine, 4.5% (4.1–5.0) for OTC codeine and 8.3% (7.8–8.9) for any codeine (prescription and/or OTC). The prevalence of last 12-month NMU for prescription codeine was 2.1% (1.9–2.4) in Germany and 1.9% (1.7–2.2) in Italy. Conclusion The prevalence of last 12-month NMU of any codeine product is approximately eight times greater in Spain and four times greater in the UK compared to Germany and Italy where the drug is only available by prescription. While other factors may contribute, these findings suggest that availability of codeine OTC is associated with greater NMU.

           iohexol-based glomerular filtration rate in paediatric patients

    • Free pre-print version: Loading...

      Abstract: Purpose Estimated glomerular filtration rate (eGFR) equations reflect kidney function imprecisely. We aimed to describe whether iohexol-based GFR or eGFRs predict clearance of cefepime, piperacillin, and tazobactam in pharmacokinetic (PK) models in this population and its clinical significance. Methods Hospitalized patients (0.5–25 years) with haemato-oncological disease and infection receiving cefepime or piperacillin/tazobactam were included. PK samples were collected at a steady state concomitantly with samples for iohexol-based GFR. PK models were developed in NONMEM. Weight, postmenstrual age, iohexol-based GFR, different eGFR equations (Schwartz updated, Lund-Malmö revised, CKD-EPI, Bouvet, Schwartz cystatin C-based) were tested as covariates. Probabilities of neurotoxic/therapeutic concentrations were assessed by simulations. Results Fifteen patients receiving cefepime and 17 piperacillin/tazobactam were included (median (range) age 16.2 (1.9–26.0) and 10.5 (0.8–25.6) years, iohexol-based GFR 102 (68–140) and 116 (74–137) mL/min/1.73 m2, respectively). Two-compartment model provided the best fit for all drugs. Weight was covariate for central and peripheral compartment, clearance and intercompartmental clearance (only tazobactam), and postmenstrual age for clearance (excluding cefepime). Iohexol-based GFR was the best predictor of clearance. The model of cefepime without vs with iohexol-based GFR underestimated the probability of neurotoxic concentrations (28.3–28.6% vs 52.1–69.3%) and overestimated the probability of therapeutic concentrations (> 90% vs 81.9–87.1%) in the case of iohexol-based GFR 70–80 and 130–140 mL/min/1.73 m2, respectively. Conclusion Iohexol-based GFR can predict better than eGFRs the clearance of cefepime, piperacillin, and tazobactam in children and young adults with haemato-oncological disease and infection, warranting further investigation as an indicator of renal function to improve targeting of therapeutic window.

      Abstract: Purpose Heart rate reduction (HR) is a cornerstone in heart failure therapy as it improves patient outcomes. The aim of this study is to evaluate short-term effect of ivabradine on NT-Pro BNP and neopterin in heart failure patients and assess the association between HR and these biomarkers. Methods Sixty patients on standard heart failure therapy were randomly allocated into ivabradine group (n = 30) and non-ivabradine group (n = 30). Ivabradine 5 mg twice daily was given for 3 months. Lipid profile and kidney functions were performed and blood samples for NT-Pro BNP and neopterin were analysed at baseline and after 3 months of intervention in both groups. Results There was a significant improvement in NYHA class in ivabradine group (p < 0.001). Ejection fraction was improved in ivabradine and non-ivabradine groups after intervention (p < 0.001), with a greater improvement in ivabradine group (p = 0.026). Heart rate was reduced in ivabradine group (p < 0.001) and non-ivabradine group (p < 0.001) yet greater reduction was seen in ivabradine group (p < 0.001). Serum creatinine and blood urea nitrogen were reduced in ivabradine group (Scr: p = 0.001, BUN: p = 0.001). NT-Pro BNP and neopterin levels significantly decreased in ivabradine group (NT-Pro BNP: p < 0.001, neopterin p < 0.001). Significant positive correlation was found between HR and biomarker levels after intervention (NT-Pro BNP: r = 0.475, p < 0.001, neopterin: r = 0.384, p = 0.002). Conclusion Ivabradine therapy reduced levels of both biomarkers which correlated well with HR. Biomarker levels might provide a tool for assessing ivabradine effectiveness in HF.

  • Moderation of buprenorphine therapy for cocaine dependence efficacy by
           variation of the Prodynorphin gene

    • Free pre-print version: Loading...

      Abstract: Purpose The aim of this secondary analysis was to identify prodynorphin (PDYN) genetic markers moderating the therapeutic response to treatment of cocaine dependence with buprenorphine/naloxone (Suboxone®; BUP). Methods Cocaine-dependent participants (N = 302) were randomly assigned to a platform of injectable, extended-release naltrexone (XR-NTX) and one of three daily medication arms: 4 mg BUP (BUP4), 16 mg BUP (BUP16), or placebo (PLB) for 8 weeks (Parent Trial Registration: Protocol ID: NIDA-CTN-0048, Clinical Trials.gov ID: NCT01402492). DNA was obtained from 277 participants. Treatment response was determined from weeks 3 to 7 over each 1-week period by the number of cocaine-positive urines per total possible urines. Results In the cross-ancestry group, the PLB group had more cocaine-positive urines than the BUP16 group (P = 0.0021). The interactions of genetic variant × treatment were observed in the rs1022563 A-allele carrier group where the BUP16 group (N = 35) had fewer cocaine-positive urines (P = 0.0006) than did the PLB group (N = 26) and in the rs1997794 A-allele carrier group where the BUP16 group (N = 49) had fewer cocaine-positive urines (P = 0.0003) than did the PLB group (N = 58). No difference was observed in the rs1022563 GG or rs1997794 GG genotype groups between the BUP16 and PLB groups. In the African American-ancestry subgroup, only the rs1022563 A-allele carrier group was associated with treatment response. Conclusion These results suggest that PDYN variants may identify patients who are best suited to treatment with XR-NTX plus buprenorphine for cocaine use disorder pharmacotherapy.

  • Colorectal cancer chemotherapy: can sex-specific disparities impact on
           drug toxicities'

    • Free pre-print version: Loading...

      Abstract: Purpose Given the biological differences between females and males, sex-specific evaluations should be carried out to obtain better cancer prevention, diagnosis, and treatment strategies. To this purpose, our aim was to evaluate sex differences for toxicity in a cohort of colorectal cancer (CRC) patients undergoing chemotherapy. Methods We performed a retrospective study in 329 CRC patients. Differences between males and females were tested performing the Mann-Whitney U test or the Fisher exact test. Multivariate logistic regression models were computed to evaluate the association between sex and risk of chemotherapy agent-related toxicity. Results According association sex toxicity, significant differences were observed in the median number of episodes of nausea (p = 0.044), vomit (p = 0.007), heartburn (p = 0.022), thrombocytopenia (p = 0.005), mucositis (p = 0.024). Moreover, statistically significant differences between males and females were observed in the distribution of the highest toxicity grades of nausea (p = 0.024), heartburn (p = 0.016), and thrombocytopenia (p = 0.034). Females have an increased risk of vomit (p = 0.002), alopecia (p = 0.035), heartburn (p = 0.005), mucositis (p = 0.003), and lower risk for thrombocytopenia (p = 0.005). Conclusion According to the association of sex chemotherapy agent-related toxicities, females resulted on average at a significant increased risk of more common adverse events (constipation, dysgeusia, alopecia, heartburn, vomit, asthenia, nausea, pain events, and mucositis). Sex-tailored CRC chemotherapy treatment is necessary to obtain efficacy avoiding toxicity, based on patients’ biological and genetic characteristics, a vision that would change CRC setting, a stable disease but still orphan of a real tailored approach.

  • Reappraising the role of class Ic antiarrhythmics in atrial fibrillation

    • Free pre-print version: Loading...

      Abstract: Purpose The objective of the present systematic review was to compare the effectiveness and safety of class Ic agents for cardioversion of paroxysmal atrial fibrillation (AF), in patients with and without structural heart disease (SHD). Methods We focused on RCTs enrolling at least 50 adult patients with electrocardiogram-documented paroxysmal AF that compared either two pharmacological class Ic cardioversion agents (flecainide, propafenone), regardless of study design (parallel or crossover). We searched MEDLINE and the Cochrane Central Register of Controlled Trials. Initial search was performed from inception to 15 July 2021 with no language restrictions. Results Intravenous flecainide is the most effective option for pharmacologic cardioversion of AF since only 2 patients need to be treated in order to cardiovert one more within 4 h. Most importantly, class Ic agents appear to be safe in the context of pharmacologic cardioversion of AF irrespective of the presence of SHD, pointing towards a possible reappraisal of the role in this setting. Conclusion We suggest that class Ic agents (with flecainide appearing to be more effective) should be used for pharmacologic cardioversion in stable AF patients presenting in emergency department with unknown medical history, after excluding severe cardiac disease through a bedside examination.

  • Selective serotonin reuptake inhibitors in the treatment of depression,
           anxiety, and post-traumatic stress disorder in substance use disorders: a
           Bayesian meta-analysis

    • Free pre-print version: Loading...

      Abstract: Purpose Examine SSRIs’ efficacy in treating depression, anxiety, PTSD, and substance use in individuals with addiction. Methods From their inception until August 6, 2021, we searched Google Scholar, PubMed, Scopus, OVID MEDLINE, and Academic Search Complete. We included randomized controlled trials (RCTs) and omitted open-label studies. Bayesian analysis was performed. Bayes factor (BF) established efficacy and tau (τ) statistical heterogeneity. The RoB2 method assessed potential biases. Subgroup analysis was carried out to determine SSRI performance. Treatment duration, SSRI dosage, and attrition rate were all examined in meta-regression. Results We investigated 64 RCTs with 6128 participants. SSRIs reduced depressive symptoms in opioid, alcohol, cocaine, cannabis, and nicotine use disorders (d = 0.353, BF > 99); social anxiety symptoms in alcohol use disorder (d = 0.875, BF > 99); and generalized anxiety symptoms in opioid, alcohol, cocaine, marijuana, and nicotine use disorders (d = 0.346, BF = 4.236). Evidence for PTSD was inconclusive. SSRIs facilitated abstinence for opioid, alcohol, cocaine, cannabis, and nicotine use (d = 0.325, BF > 99); reduced craving for alcohol, cocaine, and nicotine use (d = 0.533, BF = 24.129); and reduced alcohol use (d = 0.452, BF > 99) and cocaine use (d = 0.255, BF = 3.87). Fluoxetine showed the highest antidepressant effect. There was no effect of attrition rate, SSRI dosage, or treatment length on SSRI's efficacy. Conclusions Results support the use of SSRIs to treat substance use, depression, and anxiety in individuals with addiction. Protocol registration PROSPERO registration number: CRD42020164944.
