Abstract
Testing for hepatitis C in hospital emergency departments (ED) and linkage to care to clinics have been reported to provide the most opportunity for screening patients and facilitating continuum of care. Treatment model initiatives have expanded to include telehealth services and open treatment capacity to non-physician providers, such as pharmacists. This study's objective was to assess the impact of implementing automated routine screening for hepatitis C virus (HCV) and a clinical pharmacist into the interdisciplinary care model on HCV diagnosis and treatment outcomes. This retrospective cohort study compared outcomes in a pre-intervention and post-intervention group. Patients were screened and diagnosed with HCV at Jersey City Medical Center (JCMC) and completed linkage to care at JCMC Center for Comprehensive Care. Interventions were the implementation of automated routine HCV screening in the ED and addition of a clinical pharmacist to the interdisciplinary patient care model. Primary endpoints analyzed the number of patients who have achieved sustained virologic response after 12 weeks of treatment (SVR12) and patients who have completed treatment with no reported record of SVR12. Secondary endpoints analyzed the number of patients lost to follow-up, appointment type, time spent in appointments, and clinical pharmacist specialist interventions. Data was collected as categorical variables and chi-squared tests assessed if there were differences between the two samples. Data was collected from 46 patients in the pre-intervention group and 37 patients in the post-intervention group. Patients consisted of mostly males. Ages ranged from 27 to 83 years old. Race included Black, White, Asian, and Other. This study's results showed the positive impact on implementation of routine screening, telehealth services, and an interdisciplinary team approach to HCV diagnosis and management. Given the timeframe, it also showed the potential positive impact on these interventions during a global pandemic.

Comparative analysis of potential drug-drug interactions in a public and private hospital among chronic kidney disease patients in Khyber Pakhtunkhwa: A retrospective cross-sectional study. PLoS One 2023; 18:e0291417. [PMID: 37773947 PMCID: PMC10540949 DOI: 10.1371/journal.pone.0291417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 08/29/2023] [Indexed: 10/01/2023] Open
Abstract
INTRODUCTION Chronic kidney disease (CKD) is a significant public health challenge due to its rising incidence, mortality, and morbidity. Patients with kidney diseases often suffer from various comorbid conditions, making them susceptible to potential drug-drug interactions (pDDIs) due to polypharmacy and multiple prescribers. Inappropriate prescriptions for CKD patients and their consequences in the form of pDDIs are a major challenge in Pakistan. AIM This study aimed to compare the incidence and associated risk factors of pDDIs among a public and private sector hospital in Khyber Pakhtunkhwa, Pakistan. METHOD A retrospective cross-sectional study design was conducted to compare pDDIs among public and private sector hospitals from January 2023 to February 2023. Patients profile data for the full year starting from January 1 2022 to December 302022, was accessed All adult patients aged 18 years and above, of both genders, who currently have or have previously been diagnosed with end-stage renal disease (ESRD) were included. For assessing pDDIs, patient data was retrieved and checked using Lexicomp UpToDate® for severity and documentation of potential drug-drug interactions. RESULTS A total of 358 patients' data was retrieved (with n = 179 in each hospital); however, due to incomplete data, n = 4 patients were excluded from the final analysis. The prevalence of pDDIs was found to be significantly higher in private hospitals (84.7%) than in public hospitals (26.6%), with a p-value <0.001. Patients in the age category of 41-60 years (AOR = 6.2; p = 0.008) and those prescribed a higher number of drugs (AOR = 1.2; p = 0.027) were independently associated with pDDIs in private hospitals, while the higher number of prescribed drugs (AOR = 2.9; p = <0.001) was an independent risk factor for pDDIs in public hospitals. The majority of pDDIs (79.0%) were of moderate severity, and a significant number of patients (15.1%) also experienced major pDDIs, with a p-value <0.001. The majority of pDDIs had fair documentation for reliability rating in both public and private hospitals. CONCLUSION The prevalence of pDDIs was higher among CKD patients at private hospitals, and most of the pDDIs were of moderate severity. A considerable number of patients also experienced major pDDIs. The risk of experiencing pDDIs was found to be higher in older patients and among those prescribed a higher number of drugs.

Abstract
Although current guidelines recommend that nearly all patients with chronic hepatitis C virus (HCV) infection receive treatment, a substantial proportion remain untreated. We conducted an administrative claims analysis to provide real-world data on treatment patterns and characteristics of treated versus untreated patients among individuals with HCV in the United States. Adults with an HCV diagnosis from 01 July 2016 through 30 September 2020 and continuous health plan enrolment for 12 months before and ≥1 month after the diagnosis date were identified in the Optum Research Database. Descriptive and multivariable analyses were conducted to evaluate the association between patient characteristics and the rate of treatment. Of 24,374 patients identified with HCV, only 30% initiated treatment during follow-up. Factors associated with increased rate of treatment included younger age versus age 75+ (hazard ratio [HR] 1.50-1.83 depending on age group), commercial versus Medicare insurance (HR 1.32), and diagnosis by a specialist versus a primary care physician (HR 2.56 and 2.62 for gastroenterology and infectious disease or hepatology, respectively) (p < .01 for all). Several baseline comorbidities were associated with decreased rate of treatment, including psychiatric disorders (HR 0.87), drug use disorders (HR 0.85) and cirrhosis (HR 0.42) (p < .01 for all). These findings highlight existing HCV treatment inequities, particularly among older patients and those with psychiatric disorders, substance use disorders or chronic comorbidities. Targeted efforts to increase treatment uptake in these populations could mitigate a considerable future burden of HCV-related morbidity, mortality and healthcare costs.

Abstract
Direct-acting antivirals (DAAs) achieve high hepatitis C virus (HCV) cure rates
and are forgiving to missed doses, but adherence–efficacy relationships have not
been well defined. Traditional adherence measures (e.g. pill counts, self-report
and pharmacy refills) over-estimate medication adherence. Newer technology-based
tools have been used to provide more objective adherence data. Herein,
electronic medication diaries (e-diaries), medication events monitoring system
(MEMS®) caps, electronic blister packs, electronic pill boxes,
video-based directly observed therapy (vDOT), artificial intelligence platforms
(AIPs), and ingestible sensor systems are described, and compared based on
existing studies using DAA. Percent adherence, predictors of adherence, and HCV
cure rates utilizing these technologies are included. DAA adherence with
e-diaries was 95–96%, MEMS® caps and ingestible biosensors were
between 95% and 97%, blister pack weekly dosing ranged 73–98%, and daily dosing
73–94%, whereas electronic pill boxes ranged between 39% and 89%, vDOT was 98%
and AIP 91–96%. Despite a wide range of adherence, high sustained virologic
response (SVR) rates (86–100%) were observed across all studies utilizing these
different technology-based tools. Current data support the forgiveness of DAA
therapies to missed doses using tools that provide more quantitative adherence
measures compared with self-report and provide insight on adherence–efficacy
relationships for contemporary DAA.

Abstract
PURPOSE Rural areas of the United States have experienced outbreaks of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections among people who use drugs (PWUD). Pharmacy-based interventions may play a crucial role in prevention and entry into care, especially when traditional health care access is limited. The willingness of rural PWUD to use pharmacies for HIV/HCV-related services remains unknown. The purpose of this study was to describe the factors associated with the perceived likelihood of participating in free pharmacy-based HIV and HCV testing among PWUD living in rural Kentucky. METHODS Baseline data from the CARE2HOPE study in five Appalachian counties in eastern Kentucky were used. Participants were recruited using respondent-driven sampling and completed interviewer-administered surveys. Guided by the Andersen and Newman Framework of Health Services Utilization, we examined distributions and correlates of items regarding willingness to participate in free pharmacy-based HIV/HCV testing using logistic regression. Analyses included individuals who reported being HIV (N = 304) or HCV (N = 185) negative. FINDINGS Seventy-five percent of PWUD reported being "very likely" to participate in free pharmacy-based HIV testing and 80% for HCV testing. Two factors were associated with being less willing to participate in free HIV testing: PWUD who previously tested for HIV (OR: 0.47, CI: 0.25-0.88) and PWUD who obtained a high school diploma or equivalent compared to those who completed less (OR: 0.50, CI: 0.26-0.99). CONCLUSION Free pharmacy-based HIV and HCV testing was invariably acceptable among most of the rural PWUD in our sample, suggesting that pharmacies might be acceptable testing venues for this population.

Abstract
OBJECTIVE A recommendation in March 2020 to expand hepatitis C virus (HCV) screening to all adults in the United States will likely increase the need for HCV treatment programs and guidance on how to provide this service for diverse populations. We evaluated a pharmacist-led HCV treatment program within a routine screening program in an urban safety-net health system in Chicago, Illinois. METHODS We collected data on all patient treatment applications submitted from January 1, 2017, through June 30, 2019, and assessed outcomes of and patient retention in the treatment cascade. RESULTS During the study period, 203 HCV treatment applications were submitted for 187 patients (>1 application could be submitted per patient): 49% (n = 91) were aged 55-64, 62% (n = 116) were male, 67% (n = 125) were Black, and 15% (n = 28) were Hispanic. Of the 203 HCV treatment applications, 87% (n = 176) of patients were approved for treatment, 91% (n = 161) of whom completed treatment. Of the 161 patients who completed treatment, 81% (n = 131) attended their sustained virologic response (SVR) follow-up visit, 98% (n = 129) of whom reached SVR. The largest drop in the treatment cascade was the 19% decline from receipt of treatment to SVR follow-up visit. CONCLUSION The pharmacist-led model for HCV treatment was effective in navigating patients through the treatment cascade and achieving SVR. Widespread implementation of pharmacist-led HCV treatment models may help to hasten progress toward 2030 HCV elimination goals.

Abstract
PURPOSE Direct-acting antivirals (DAAs) used to treat hepatitis C virus (HCV) infection are associated with significant drug-drug interactions (DDIs). Pharmacists are well positioned to identify and mitigate these DDIs. Data to guide assessment of the impact of HCV specialty pharmacy services on identifying and addressing DDIs with DAAs are lacking. The overall purpose of the study described here was to determine the incidence and severity of DDIs identified by specialty pharmacists among patients treated with DAAs prior to and 1 month into therapy. METHODS An observational, retrospective study was conducted to evaluate the impact of specialty pharmacy services in mitigating DDIs associated with use of DAAs. Adult patients with HCV infection (n = 200) who received DAAs and were enrolled with a specialty pharmacy service over a 1-year period were included. Endpoints included number, severity, and type of DDIs and DDIs per patient at baseline and 1 month into therapy, pharmacists' interventions, and safety and clinical outcomes. RESULTS Fifty-nine percent of patients had at least 1 DDI. A total of 170 DDIs were identified (137 at baseline and 33 at 1-month follow-up), and the mean number of DDIs per patient significantly decreased from baseline to 1-month follow-up (from 1.38 to 0.16, P < 0.0001). The rate of "potentially clinically significant" or "critical" interactions was significantly lower at 1-month follow-up vs baseline assessment (69.6% vs 81.7%, P < 0.0001). The most commonly identified DDIs involved acid suppressive medications (49.6% and 66.6% of DDIs at baseline and follow-up assessment, respectively) and cardiovascular medications (26.2% and 21.2%, respectively). Total number of DDI interventions was 131, with an acceptance rate of 85%. Most common intervention was patient education and monitoring. CONCLUSION Approximately 60% of patients had DDIs with DAAs. Implementing HCV specialty pharmacy services significantly decreased DDIs while maintaining SVR12.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is still one of the leading causes of chronic liver disease, with chronically infected making up approximately 1% of the global population. Of those infected, 70% (55-85%) will develop chronic HCV infection. Chronic HCV infection causes substantial morbidity and mortality, with complications including cirrhosis, end-stage liver disease, hepatocellular carcinoma, and eventually death. OBJECTIVE Therapeutic options for chronic HCV infection have evolved dramatically since 2014, with a translation from pegylated interferon and ribavirin (associated with suboptimal cure and high treatment-related toxicity) to oral direct-acting antiviral treatment. There are four classes of direct-acting antivirals which differ by their mechanism of action and therapeutic target. They are all pointed to proteins that form the cytoplasmic viral replication complex. Multiple studies have demonstrated that direct-acting antiviral therapy is extremely well tolerated, highly efficacious, with few side effects. METHODS We performed an indexed MEDLINE search with keywords regarding specific direct-acting antiviral regimes and their pharmacokinetics, drug-drug interactions, and metabolism in specific settings of pregnancy, lactation, liver cirrhosis, liver transplantation and HCC risk, kidney failure and kidney transplantation. RESULTS We present a comprehensive overview of specific direct-acting antiviral metabolism and drug-drug interaction issues in different settings. CONCLUSION Despite its complex pharmacokinetics and the possibility of drug-drug interactions, direct-acting antivirals are highly efficacious in providing viral clearance, which is an obvious advantage compared to possible interactions or side effects. They should be administered cautiously in patients with other comorbidities, and with tight control of immunosuppressive therapy.

Abstract
BACKGROUND AND AIM Patients with chronic hepatitis C (CHC) frequently associated comorbidities and concomitant medication. Sustained virological response (SVR12) has been related to an increase in cholesterol serum levels and in peripheral vascular resistance. Our aim was to evaluate the impact of SVR12 on the use of concomitant medication and serum lipid profile. METHODS Prospective study including patients treated with direct-acting antivirals who had achieved the SVR12. Clinical data and concomitant drugs were analysed at baseline and at least 1 year after SVR12. Differences from baseline to follow-up in the concomitant medication were evaluated by Stuart-Maxwell test and lipid profile by Wilcoxon signed-rank test. Patients were categorized according to the increase/decrease in the number of drugs included in each class (Anatomical Therapeutic Chemical classification system). RESULTS Two hundred twenty-six patients with SVR12 were included, 73.5% were receiving concomitant drugs (49.6% with antihypertensive effect, 30.5% antacids, 16.4% anti-diabetic drugs, and 7.1% lipid-lowering agents). One year after SVR12, total cholesterol serum levels increased from 161 to 179 mg/dl (P < 0.001) and, after a median time of 25.7 months, the use of lipid-lowering drugs increased from 7.8 to 11.5% (P = 0.009). In addition, we observed a trend to use more antihypertensive drugs in older patients (P = 0.06), especially in those with cirrhosis. Anxiolytics decreased after SVR12 from 13.7 to 10.6% (P = 0.035). CONCLUSION CHC cure is associated with a significant increase in cholesterol serum levels and the use of lipid-lowering agents, as well as the use of drugs with antihypertensive effect in older patients.

Abstract
OBJECTIVES Direct-acting antivirals are the recommended treatment for hepatitis C-infected patients. Drug-drug interactions with concomitant treatments can cause lack of effectiveness and/or safety. The objective of this study is to characterise drug-drug interactions of direct-acting antivirals and to analyse their influence both on the effectiveness of antiviral treatment and on the overall safety of pharmacological treatment in hepatitis C-infected patients. METHODS Observational and prospective cohort study for 3 years in the pharmaceutical care outpatient consultation of a general hospital, undertaking detection, evaluation and management of drug-drug interactions by clinical pharmacists and physicians. The main outcome measures were sustained virologic response at week 12 for effectiveness and serious drug-related adverse events for safety. Multivariate statistical analysis applied to: (a) patient basal characteristics related to presence of drug-drug interactions; (b) previous antiviral treatments, viral genotype, cirrhosis, decompensations and presence of drug-drug interactions related to the effectiveness of direct-acting antivirals. RESULTS Of a total of 1092 patients, the majority of them were men, around 60 years old and HCV-genotype 1 mono-infected, with a high basal viral load, naive to antiviral treatment, treated with ledipasvir/sofosbuvir and without cirrhosis. 24.5% had drug-drug interactions. Proton pump inhibitors were the concomitant drugs that caused the most drug-drug interactions. Age ≥65 years and direct-acting antivirals based on protease inhibitors were independently related to the presence of drug-drug interactions (p≤0.012). All (100%) of the therapeutic recommendations based on detected drug-drug interactions were implemented; 97.7% of patients with interactions versus 99.0% without them reached sustained virologic failure (p=0.109). The serious adverse events rates were 1.5% and 1.3% in patients with and without drug-drug interactions, respectively (p=0.841). CONCLUSIONS Drug-drug interactions are frequent among hepatitis C-infected patients receiving treatment with direct-acting antivirals. However, the collaboration between physicians and clinical pharmacists makes it possible to detect, evaluate, avoid or clinically manage these drug-drug interactions, in order to maintain whole treatment therapeutic safety and the effectiveness of direct-acting antivirals.

Abstract
Objective To describe comorbidities and concomitant medications in patients initiating treatment for hepatitis C virus (HCV) infection with direct-acting antiviral (DAA) regimens in Belgium. Methods This was a noninterventional, observational, multicenter study of data from patient charts. Adult patients with HCV infection receiving second-generation DAA therapy were included. Comorbidities were assessed at the time of HCV treatment initiation. Concomitant medications were recorded at the time of diagnosis and at treatment initiation. Potential clinically relevant drug-drug interactions (DDIs) were assessed based on information available at www.hep-druginteractions.org. The primary objective was to describe concomitant medication use ; secondary objectives were to describe modifications in concomitant therapies and comorbidities. Results 405 patients were included. A total of 956 comorbidities were reported by 362 patients (median, 2 ; range, 0-15). The most common comorbidities were hypertension (27.2%) ; HIV coinfection (22.5%), and type 2 diabetes mellitus (14.3%). Overall, 1455 concomitant medications were being taken by 365 patients (90.1% ; median, 3 ; range 0-16). The most common concomitant medications were psycholeptics (28.6%), antiviral agents (24.2%), and medications for acid-related disorders (21.0%) Overall, 74/365 (20.3%) patients receiving a concomitant medication required an adaptation to their concomitant medication. The medications that most frequently required change were drugs for acid-related disorders (n = 14) and antiviral drugs (n = 5) ; those that were most frequently stopped were lipid-modifying drugs (n = 25) and drugs for acid-related disorders (n = 13). Conclusion Physicians are aware of the potential for DDIs with DAAs, but improved alignment between clinical practice and theoretical recommendations is required.

Abstract
Background/Aims Direct‐acting antivirals (DAAs) have been approved for hepatitis C virus (HCV) treatment in patients with end-stage renal disease (ESRD) on hemodialysis. Nevertheless, the complicated comedications and their potential drug-drug interactions (DDIs) with DAAs might limit clinical practice in this special population. Methods The number, class, and characteristics of comedications and their potential DDIs with five DAA regimens were analyzed among HCV-viremic patients from 23 hemodialysis centers in Taiwan. Results Of 2,015 hemodialysis patients screened in 2019, 169 patients seropositive for HCV RNA were enrolled (mean age, 65.6 years; median duration of hemodialysis, 5.8 years). All patients received at least one comedication (median number, 6; mean class number, 3.4). The most common comedication classes were ESRD-associated medications (94.1%), cardiovascular drugs (69.8%) and antidiabetic drugs (43.2%). ESRD-associated medications were excluded from DDI analysis. Sofosbuvir/velpatasvir/voxilaprevir had the highest frequency of potential contraindicated DDIs (red, 5.6%), followed by glecaprevir/pibrentasvir (4.0%), sofosbuvir/ledipasvir (1.3%), sofosbuvir/velpatasvir (1.3%), and elbasvir/grazoprevir (0.3%). For potentially significant DDIs (orange, requiring close monitoring or dose adjustments), sofosbuvir/velpatasvir/voxilaprevir had the highest frequency (19.9%), followed by sofosbuvir/ledipasvir (18.2%), glecaprevir/pibrentasvir (12.6%), sofosbuvir/velpatasvir (12.6%), and elbasvir/grazoprevir (7.3%). Overall, lipid-lowering agents were the most common comedication class with red-category DDIs to all DAA regimens (n=62), followed by cardiovascular agents (n=15), and central nervous system agents (n=10). Conclusions HCV-viremic patients on hemodialysis had a very high prevalence of comedications with a broad spectrum, which had varied DDIs with currently available DAA regimens. Elbasvir/grazoprevir had the fewest potential DDIs, and sofosbuvir/velpatasvir/voxilaprevir had the most potential DDIs.

Abstract
PURPOSE The design, implementation, and assessment of a comprehensive pharmaceutical care program (CPCP) for hepatitis C virus (HCV)-infected patients treated with direct-acting antivirals (DAA) are described. SUMMARY The advent of DAA regimens has caused the evolution of the role of hospital pharmacists, leading to the development of more specialized models of pharmaceutical care. Three clinical pharmacists were incorporated into the pharmacy department of a general tertiary teaching hospital in Madrid, Spain, with the aim of developing and implementing a CPCP for HCV-infected patients. Pharmacists were responsible for proposing standards and local guidelines to physicians, monitoring adherence to guidelines, managing drug interactions and adverse drug events (ADEs), providing patient education, and evaluating health outcomes and costs. Implementation steps included (1) estimation of the healthcare demand and pharmacy resources, (2) definition of the workflow of the CPCP, (3) definition of the treatment care plan, for which tools were developed to support pharmaceutical validation, detection, and management of ADEs and drug-drug interactions, and (4) program assessment in terms of safety and cost-effectiveness. The pharmacists' interventions performed, severity of errors intercepted, and patients' satisfaction with the CPCP were also assessed. This CPCP demonstrates that the involvement of the pharmacist throughout the care plan prevents harmful medication errors in this population (0.1 per patient) and prompts significant cost savings (€1.2 million for 1,930 treated patients). CONCLUSION The implementation of a CPCP developed by hospital pharmacists for patients treated with DAA for HCV infection is an effective approach for preventing harmful medication errors and improving cost- effectiveness.

Abstract
BACKGROUND Hospitalized patients with tuberculosis (TB) are prescribed with drugs having high risk of potential drug-drug interactions (pDDIs) and adverse drug effects (ADEs). OBJECTIVES To explore the adverse effects of anti-tuberculosis (anti-TB) drugs and the prevalence and predictors of pDDIs in hospitalized patients with TB. METHODS Clinical profiles of 436 TB patients were reviewed for adverse effects induced by anti-TB drugs and screened for pDDIs using Micromedex-DrugReax. Prevalence and severity levels of pDDIs were reported. Odds ratios for predictors were calculated using logistic regression analysis. RESULTS Of total 436 patients, adverse effects of anti-TB drugs were found in 36%. ADEs were highly prevalent in patients with high doses of anti-TB drugs. Hepatotoxicity, neuropathy, insomnia, arthralgia, psychosis, hematological alterations, skin rashes, red color stool, diplopia, and photophobia were the identified ADEs. All drugs types- and anti-TB drugs-pDDIs were reported in 78.2% and 55.7%, respectively. Major-pDDIs of anti-TB drugs were identified in 55.5%. Total 1090 anti-TB drugs pDDIs were found, among them, 55.6% were of major- and 40.5% were of moderate-severity. Significant association was observed for the pDDIs with ≥7 prescribed medicines (P < 0.001). Potential adverse outcomes of the most frequent interactions were hepatotoxicity, decreased drug's effectiveness, QT-interval prolongation, nephrotoxicity, and gastrointestinal ulceration. CONCLUSIONS Patients with TB present with a considerable number of clinically important pDDIs and ADEs (particularly hepatotoxicity). TB patients should be monitored for adverse effects of anti-TB drugs. Attention should be given to major-pDDIs. Patients more at risk to interactions should be identified and monitored for related adverse outcomes.

Abstract
BACKGROUND Hospitalized patients with malaria often present with comorbidities or associated complications for which a variety of drugs are prescribed. Multiple drug therapy often leads to drug-drug interactions (DDIs). Therefore, the current study investigated the prevalence, levels, risk factors, clinical relevance, and monitoring parameters/management guidelines of potential DDIs (pDDIs) among inpatients with malaria. METHODS A retrospective cohort study was carried out at two tertiary care hospitals. A total of 398 patients' profiles were evaluated for pDDIs using the Micromedex Drug-Reax®. Odds ratios were calculated to identify the strength of association between presence of DDIs and potential risk factors via logistic regression analysis. Further, the clinical relevance of frequent pDDIs was investigated. RESULTS Of 398 patients, pDDIs were observed in 37.2% patients, while major-pDDIs in 19.3% patients. A total of 325 interactions were found, of which 45.5% were of major- and 34.5% moderate-severity. Patients with the most common pDDIs were found with signs/symptoms and abnormalities in laboratory findings representing nephrotoxicity, hepatotoxicity, QT interval prolongation, and reduced therapeutic efficacy. The following drug pairs reported the highest frequency of adverse events associated with the interactions; calcium containing products-ceftriaxone, isoniazid-rifampin, pyrazinamide-rifampin, isoniazid-acetaminophen, and ciprofloxacin-metronidazole. The adverse events were more common in patients prescribed with the higher doses of interacting drugs. Multivariate regression analysis showed statistically significant association of pDDIs with 5-6 prescribed medicines (p = 0.01), > 6 prescribed medicines (p < 0.001), > 5 days of hospital stay (p = 0.03), and diabetes mellitus (p = 0.04). CONCLUSIONS PDDIs are commonly observed in patients with malaria. Healthcare professional's knowledge about the most common pDDIs could help in preventing pDDIs and their associated negative effects. Pertinent clinical parameters, such as laboratory findings and signs/symptoms need to be checked, particularly in patients with polypharmacy, longer hospital stay, and diabetes mellitus.

Abstract
PURPOSE The optimal health care delivery models for providing services to patients with infections caused by hepatitis C virus (HCV) remain unknown. Pharmacist involvement may be a key component of optimal HCV care delivery. We examined the comparative effectiveness of a pharmacist-managed HCV clinic versus a pharmacist-assisted HCV clinic. METHODS This retrospective cohort study used electronic health record data on patients ≥18 years old initiating HCV treatment at a pharmacist-managed clinic or a pharmacist-assisted clinic within a single health-system between January 2015 and June 2017. Outcomes included treatment completion, sustained virologic response 12 weeks following treatment completion (SVR-12), and dispensation of direct-acting antiviral agents at the institution-based specialty pharmacy. Inverse probability of treatment-weighted (IPTW) logistic regression models were used to compare outcomes between the 2 clinic models. RESULTS A total of 127 patients initiated HCV treatment therapy: 64 patients from the pharmacist-managed clinic and 63 patients from the pharmacist-assisted clinic. The cohort had a mean age of 55 years, was 51% male, and 68% white. In IPTW analyses, there was no difference in treatment completion (odds ratio [OR], 1.1; 95% confidence interval [CI], 0.1-13.8; p = 0.93), achievement of sustained virologic response at 12 months (SVR-12) (OR, 1.0; 95% CI, 0.2-4.5; p = 0.62), or use of institution-based specialty pharmacy (OR, 0.6; 95% CI, 0.2-1.7; p = 0.33) between pharmacist-managed and pharmacist-assisted clinics. CONCLUSION There were no significant differences in outcomes between patients receiving care at the pharmacist-managed HCV clinic and the pharmacist-assisted clinic. Given the frequency of SVR-12 achieved in both groups, both pharmacist-managed and pharmacist-assisted clinic models may be reasonable alternatives for providing outpatient HCV care.

Abstract
BACKGROUND AND OBJECTIVE Drug-drug interactions need to be considered to optimize the pharmacotherapeutic outcome of direct-acting antivirals. The aim of this study was to report on possible drug-drug interactions between ledipasvir/sofosbuvir and other medications received by children and adolescents with hepatitis C virus, in addition to suggested management for these drug-drug interactions. METHODS Hepatitis C virus-infected children and adolescents, 12-17 years of age and/or weighing ≥ 35 kg, who presented to the Pediatric Hepatology Unit at Cairo University Pediatric Hospitals for ledipasvir/sofosbuvir treatment were included. Medication history was taken including long-term medications for chronic conditions and on-demand medications for inter-current illnesses. Medications were reviewed by the Kasr Alainy Drug Information Center to identify possible drug-drug interactions with prescribed ledipasvir/sofosbuvir and their management. HEP Drug Interactions provided by the University of Liverpool, Lexicomp®, and Medscape were the utilized references. Each drug-drug interaction was assigned a risk rating of A, B, C, D, or X. RESULTS Sixty hepatitis C virus-infected children and adolescents assigned to receive ledipasvir/sofosbuvir were enrolled. Thirty percent of patients had associated chronic co-morbid conditions. The overall number of medications received was 48; 39 were prescribed as long-term medications with a median of 3 (interquartile range 4.24) medications per patient. Proton pump inhibitors, antacids, histamine H2 receptor antagonists, sodium bicarbonate, and colchicine were reported to be associated with a drug-drug interaction risk D necessitating therapy modification, which occurred prior to administration. CONCLUSIONS Early identification and prompt response to drug-drug interactions with the aid of pharmacists optimize the pharmacotherapeutic outcome and eliminate possible morbidities when using direct-acting antivirals in children and adolescents with hepatitis C virus.

Abstract
Introduction Sustained virologic response (SVR) rates in patients with hepatitis C virus (HCV) monoinfection and human immunodeficiency virus (HIV)/HCV coinfection treated with direct acting antiviral (DAA) therapy are similar in clinical trials. The objective of this study was to examine differences in patient characteristics, drug-drug interactions, and treatment pathways between these groups in a real-world clinical setting. Methods We performed an ambispective review of patients prescribed DAA therapy between September 2015 and April 2018 at a tertiary academic center. The primary endpoint was time from a decision to treat to treatment initiation. Secondary endpoints included patient characteristics; frequency and type of DAA medication interactions; frequency, type, and timing of antiretroviral therapy (ART) changes; and treatment outcomes. Results Three hundred and twelve patients were included. Almost half (43%) were HIV/HCV coinfected. Patients with HIV/HCV coinfection were more likely to be African American (p<0.001), have a diagnosed psychiatric disorder (p<0.001) and have a higher pill burden (p = 0.014). Patients with HIV/HCV coinfection were more likely to report an alcohol abuse history (p<0.001), injection drug use history (p<0.024), or active use of illicit substances (p = 0.019). In a multivariable regression model assessing the primary endpoint, time to treatment initiation was increased in patients requiring a change in ART therapy (OR = 9.2, p < 0.001) or a non-ART medication adjustment (OR = 2.4, p = 0.003), and in patients with Medicaid (OR = 6.7, p < 0.001). After controlling for all these factors, HIV/HCV coinfection still significantly impacted time to treatment initiation (OR = 1.7, p = 0.020). The groups had similar rates of drug interaction frequency, treatment completion, observed SVR, and side effects. Conclusions Patients with HIV/HCV coinfection are more likely to have a variety of factors that add complexities to HCV treatment. In addition to these challenges, patients with HIV/HCV coinfection experience a longer time to treatment initiation while patients with HCV monoinfection were more frequently lost to care. Care delivery models may incorporate this data to improve patient engagement, access, and outcomes.

[PMID: 31594667 DOI: 10.1016/j.jfma.2019.09.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 08/19/2019] [Accepted: 09/20/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND/PURPOSE The assessment of drug-drug interaction (DDI) is important not only for safety but also for maintaining the efficacy of direct acting antivirals in chronic hepatitis C (CHC). This study aims to evaluate DDI before and during elbasvir/grazoprevir (EBR/GZR) treatment. METHODS CHC patients who treated with EBR/GZR in five hospitals were enrolled. The patients' demographic data, comorbidities, concomitant medications taken before and during EBR/GZR were recorded. DDI was evaluated using a tool from the HEP Drug Interactions (www.hep-druginteractions.org) website. In addition to the evaluation of DDI for EBR/GZR, the virtual DDI of ledipasvir/sofosbuvir (LDV/SOF), sofosbuvir/velpatasvir (SOF/VEL) and glecaprevir/pibrentasvir (GLE/PIB) were evaluated. Degrees of DDI were classified as "do not co-administer", "potential interaction", and "potentially weak interaction". RESULTS A total of 460 patients were enrolled. At baseline, 80.1% of patients had one or more comorbidities and 72.8% took one or more medications. Cardiovascular diseases (43.9%), gastrointestinal diseases (37.4%), and metabolic diseases (36.7%) were the three most common comorbidities. The prevalence of DDI before EBR/GZR treatment was 12.8% (59 patients). Among the same population, the prevalence of virtual DDI of SOF/VEL, GLE/PIB, and LDV/SOF were 38.5% (179 patients), 48.8% (220 patients), and 57.0% (262 patients), respectively. During EBR/GZR treatment, 167 patients (36.3%) took newly prescribed medications. One patient (0.2%) and seven patients (1/5%) exhibited do-not-co-administer and potential interaction with EBR/GZR, respectively. CONCLUSION DDI was limited in treatment with EBR/GZR. DDI can occur upon the administering of a new medication during antiviral treatment and attention should be paid to it. TRIAL REGISTRATION NUMBER NCT03706222.

Abstract
Introduction: Hospitalized patients with urinary tract infections (UTIs) often present with comorbid illnesses and are subsequently prescribed multiple medications, which increases the likelihood of drug-drug interactions. Therefore, this study aimed to explore the prevalence, levels, risk factors, and clinical relevance of potential drug-drug interactions (pDDIs) in hospitalized patients with UTIs. Secondly, we aimed to develop management guidelines and identify monitoring parameters for the most frequent interactions. Methods: A retrospective cross-sectional study was conducted in internal medicine wards of two tertiary care hospitals in Peshawar, Khyber Pakhtunkhwa, Pakistan. The clinical profiles of 422 patients with UTIs were reviewed for pDDIs using the Micromedex Drug-Reax®. Logistic regression was applied to assess the association of pDDIs with various risk factors. The clinical relevance of frequent pDDIs was identified by assessing the potential adverse outcomes of pDDIs including patients’ signs, symptoms, and abnormal laboratory findings. Results: Of 422 patients, at least one pDDI was identified in 62.3% patients, while 40% patients had at least one major pDDI. A total of 1,086 pDDIs were identified, of which 53.4% and 39.3% were of moderate and major severity, respectively. Patients with most frequent pDDIs were presented with hypoglycemia, hepatotoxicity, nephrotoxicity, hypertension, and decreased therapeutic response. These adverse events were more prevalent in patients taking higher doses of interacting drugs. Multivariate regression analysis revealed significant association of pDDIs with six or more medicines (p < 0.001), diabetes mellitus (p < 0.001), ischemic heart disease (p = 0.02), and congestive cardiac failure (p = 0.04). Conclusions: Patients with UTIs present with a considerable number of clinically important pDDIs. Polypharmacy, diabetes mellitus, ischemic heart disease, and congestive cardiac failure increase the risk of pDDIs. Knowledge about the most frequent pDDIs will enable healthcare professionals to implement optimized monitoring and management strategies regarding associated adverse consequences in order to ensure patient safety. Most of the interactions can be managed by considering alternative therapy and dose reduction.

Prevalence of the potential drug-drug interactions between pangenotypic direct-acting antivirals and the concomitant medications associated with patients with chronic hepatitis C virus infection in Spain. GASTROENTEROLOGIA Y HEPATOLOGIA 2019; 42:465-475. [PMID: 31451229 DOI: 10.1016/j.gastrohep.2019.03.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2018] [Revised: 03/11/2019] [Accepted: 03/29/2019] [Indexed: 02/06/2023]
Abstract
OBJECTIVE To determine the comorbidity and potential for drug-drug interactions (DDIs) among pangenotypic direct-acting-antivirals (pDAAs) and the concomitant medications associated with chronic hepatitis C (CHC) patients in routine clinical practice in Spain. METHODS Retrospective observational study. Included patients were ≥18 years, diagnosed with CHC, on antiviral treatment and required medical attention during 2017. Two groups were differentiated according to age ranges (<50 and ≥50 years). The variables collected were: age, gender, general/specific comorbidity, concomitant medication and potential DDIs (www.hep-druginteractions.org). The pDAAs analysed were: a) Sofosbuvir/Velpatasvir (SOF/VEL), b) Glecaprevir/Pibrentasvir (GLE/PIB) and c) Sofosbuvir/Velpatasvir/Voxilaprevir (SOF/VEL/VOX). Bivariate statistical analysis, P<.05. RESULTS 3,430 patients with a mean age of 56.9 years and 60.3% males were enrolled. The average Charlson index was 0.8. Age range distribution: 18-49 years (28.9%) and ≥50 years (71.1%). The average number of medications per patient/year was 3.1 (SD 2.6). The total percentage of potential DDIs was: 8.6% minor DDIs, 40.5% clinically significant DDIs and 10.0% contraindicated medication. These DDIs were greater in patients ≥50 years (8.6%, 43.8% and 12.4%, respectively, P<.001). For all ages, SOF/VEL showed a lower percentage of: minor interactions (1.3% vs. 6.6% and 5.9%, P<.001); clinically significant interactions (53.4%, vs. 77.4% and 66.3%, P<.001) and contraindicated medication (1.7% vs. 8.3% and 10.7%, P<.001) compared to GLE/PIB and SOF/VEL/VOX, respectively. CONCLUSIONS Patients with CHC present high comorbidity and concomitant medication use, particularly elderly patients, thus implying a greater exposure to potential DDIs. Although the DDI rate was considerable with the three combinations analysed, SOF/VEL showed a lower number of clinically significant interactions.

Abstract
Although direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection are highly efficacious and safe, treatment initiation is often limited in patients with neuropsychiatric disorders due to concerns over reduced treatment adherence and drug-drug interactions. Here, we report adherence, efficacy, safety and patient-reported outcomes (PROs) from an integrated analysis of registrational studies using the pangenotypic DAA regimen of glecaprevir and pibrentasvir (G/P). Patients with chronic HCV genotypes 1-6 infection with compensated liver disease (with or without cirrhosis) receiving G/P for 8, 12 or 16 weeks were included in this analysis. Patients were classified as having a psychiatric disorder based on medical history and/or co-medications. Primary analyses assessed treatment adherence, efficacy (sustained virologic response at post-treatment week 12; SVR12), safety and PROs. Among 2522 patients receiving G/P, 789 (31%) had a psychiatric disorder with the most common diagnoses being depression (64%; 506/789) and anxiety disorders (27%; 216/789). Treatment adherence was comparably high (>95%) in patients with and without psychiatric disorders. SVR12 rates were 97.3% (768/789; 95% CI = 96.2-98.5) and 97.5% (1689/1733; 95% CI = 96.7-98.2) in patients with and without psychiatric disorders, respectively. Among patients with psychiatric disorders, SVR12 rates remained >96% by individual psychiatric diagnoses and co-medication classes. Overall, most adverse events (AEs) were mild-to-moderate in severity with serious AEs and AEs leading to G/P discontinuation occurring at similarly low rates in both patient populations. In conclusion, G/P treatment was highly efficacious, well-tolerated and demonstrated high adherence rates in patients with chronic HCV infection and psychiatric disorders.

Abstract
BACKGROUND Pneumonia patients are usually hospitalized due to severe nature of the disease or for the management of comorbid illnesses or associated symptoms. Such patients are prescribed with multiple medications which increase the likelihood of potential drug-drug interactions (pDDIs). Therefore, in this study the prevalence, levels (severity and documentation), predictors (risk factors), and clinical relevance of pDDIs among inpatients diagnosed with pneumonia have been investigated. METHODS Clinical records of 431 hospitalized patients with pneumonia were checked for pDDIs using drug interactions screening software (Micromedex-DrugReax). Odds-ratios for predictors were calculated using logistic regression analysis. Clinical relevance of pDDIs was assessed by evaluation of patients' clinical profiles for potential adverse outcomes of the most frequent pDDIs. Abnormal patients' signs/symptoms and laboratory investigations indicating adverse outcomes of interactions were reported. RESULTS Of total 431 profiles, pDDIs were reported in 73.1%. Almost half of the profiles were having major-pDDIs (53.8%). Total number of pDDIs were 1318, of which 606 were moderate- and 572 were major-pDDIs. Patient's profiles identified with the most frequent interactions were presented with signs, symptoms, and abnormalities in labs indicating decrease therapeutic response, electrolyte abnormalities, hypoglycemia, bleeding, hepatotoxicity, and hypertension. These adverse events were more prevalent in patients taking higher doses of the interacting drugs as compared to lower doses. Logistic regression analysis revealed significant association for major-pDDIs with 6-10 prescribed medicines (OR = 26.1; p = 0.002), > 10 prescribed medicines (OR = 144; p < 0.001), and tuberculosis (OR = 8.2; p = 0.004). CONCLUSIONS PDDIs are highly prevalent in patients with pneumonia. Most frequent and clinically important pDDIs need particular attention. Polypharmacy and tuberculosis increase the risk of pDDIs. Identifying patients more at risk to pDDIs and careful monitoring of pertinent signs/symptoms and laboratory investigations are important measures to reduce pDDIs and their related adverse consequences.

Abstract
Background Medication reconciliation and drug-drug interaction management represent important patient safety processes completed by pharmacists as part of Hepatitis C patient care. Objectives To describe the pharmacist-led interventions of medication reconciliation and drug-drug interaction assessment, grading and management in a real-world Hepatitis C treatment cohort and to assesses the impact on patient outcomes. Setting Two Hepatitis C hospital outpatient clinics at St. James's Hospital, Dublin. Method Patients treated with Hepatitis C direct acting anti-viral agents between December 2014 and February 2017 were included in this retrospective cohort study. The study employed a standardised medication reconciliation proforma and drug-drug interaction reference list. Main outcome measures Analyse medication variances identified during pharmacist-led medication reconciliation. Assess the prevalence, type and severity of drug-drug interactions between direct acting anti-virals and co-medications. Assess the rate of prescriber acceptance of the pharmacist-developed drug-drug interaction management strategies. Results Among the 300 patients in this study, medication reconciliation identified 1543 co-medications, with 71% of patients prescribed co-medications which were subject to a potential drug-drug interaction. Drug-drug interaction assessments assigned a rating of severe to 68 interaction episodes. At least one co-medication was stopped during treatment in 25% of patients to facilitate drug-drug interaction management. Pharmacist proposed management recommendations were accepted by prescribers in 96.9% of cases. The sustained virological response rate among the cohort was 92.7%. Conclusions In this Hepatitis C pre-treatment pharmacist assessment analysis, a significant number of medication reconciliation variances and clinically significant drug-drug interactions were identified which present unique and important patient safety risks. Pharmacist-led management strategies aided the achievement of optimum treatment response while promoting patient safety and antiviral stewardship.

Abstract
Background The US National Viral Hepatitis Action Plan depends on additional providers to expand hepatitis C virus (HCV) treatment capacity in order to achieve elimination goals. Clinical pharmacists manage treatment and medication within interdisciplinary teams. The study’s objective was to determine sustained virologic response (SVR) rates for clinical pharmacist–delivered HCV therapy in an open medical system. Methods Investigators conducted a multicenter retrospective cohort study of patients initiating direct-acting antivirals from January 1, 2014, through March 12, 2018. Data included demographics, comorbidities, treatment, and clinical outcomes. The primary outcome of SVR was determined for patients initiating (intent-to-treat) and those who completed (per-protocol) treatment. Chi-square tests were conducted to identify associations between SVR and adverse reactions, drug–drug interactions, and adherence. Results A total of 1253 patients initiated treatment; 95 were lost to follow-up, and 24 discontinued therapy. SVR rates were 95.1% (1079/1134) per protocol and 86.1% (1079/1253) intent to treat. The mean age (SD) was 57.4 (10.1) years, the mean body mass index (SD) was 28.7 (6.2) kg/m2, 63.9% were male, 53.7% were black, 40.3% were cirrhotic, 88.4% were genotype 1, and 81.6% were treatment-naïve. Patients missing ≥1 dose had an SVR of 74.9%; full adherence yielded 90% (P < .0001). Conclusions HCV treatment by clinical pharmacists in an open medical system resulted in high SVR rates comparable to real-world studies with specialists and nonspecialists. These findings demonstrate the success of a clinical pharmacist–delivered method for HCV treatment expansion and elimination.

Abstract
Background Concomitant dosing of ledipasvir (LDV) and tenofovir disoproxil fumarate (TDF) results in an increased tenofovir (TFV) area under the curve (AUC). The aim of this study was to examine whether there was a correlation between the renal biomarkers retinol binding protein–4 (RBP-4) and β2 microglobulin (β2M) and tenofovir AUC. Methods The ION-4 trial enrolled HIV/hepatitis C virus–coinfected patients on nonpharmacologically boosted antiretroviral regimens with TDF-containing backbones. We assessed for a correlation between tenofovir AUC and urinary biomarkers and also for changes in serologic biomarkers with respect to clinically relevant changes in renal function (creatinine clearance decrease >25%, change in creatinine >0.2 mg/dL, change in proteinuria from negative/trace to ≥1+). Results Three hundred thirty-five patients were enrolled in the ION-4 study; their demographic characteristics have been previously described. Both RBP-4 and β2M exhibited positive correlations with tenofovir AUC. Baseline and study levels of RBP-4 and β2M were higher for patients with increases in urine proteinuria and an absolute creatinine increase. Conclusions TFV exposure is associated with increased proximal tubule urine biomarkers in participants on ledipasvir/sofosbuvir and nonpharmacologically boosted TDF-based antiretroviral regimens. Baseline proximal tubule biomarkers may predict nephrotoxicity risk if events are prevalent. Further studies assessing the predictive role of these urine biomarkers may help guide medical decision-making and risk/benefit assessments in patients with risk factors for renal dysfunction.

Abstract
BACKGROUND While direct-acting antivirals have been approved for treating hepatitis C, the guidelines highlight the importance of considering potential drug-drug interactions between DAAs and concomitant medications. AIM To assess comorbidity prevalence, concomitant medication use and potential drug-drug interactions between DAAs and concomitant medications for hepatitis C patients in Taiwan. METHODS This cross-sectional study enrolled 822 patients from May to August 2016 in Taiwan. Patient demographics, comorbidities and concomitant medications were evaluated by physician surveys. RESULTS A total of 709 (86.3%) patients had ≥1 comorbidity; the most prevalent comorbidity categories were diseases of the digestive system (40.1%), circulatory system (38.7%) and endocrine/nutritional/metabolic diseases (35.2%). Elderly patients had more comorbidities. A total of 622 (75.7%) patients received ≥1 concomitant medication; the average number of concomitant medications was 3.2. The most common concomitant medication classes were cardiovascular (34.4%), gastrointestinal (25.7%) and central nervous system drugs (22.7%). Among patients without cirrhosis or with compensated cirrhosis, contraindications were most prevalent with paritaprevir/ritonavir/ombitasvir plus dasabuvir, daclatasvir/asunaprevir and glecaprevir/pibrentasvir (13.3%, 6.0% and 5.4% respectively), and least prevalent with sofosbuvir, sofosbuvir/daclatasvir, sofosbuvir/ledipasvir and sofosbuvir/velpatasvir (0.8%, 1.3%, 1.4% and 2.1% respectively). Sofosbuvir-based regimens had no contraindications in patients with decompensated cirrhosis. CONCLUSION Our population represented an elderly demographic, with a high prevalence of comorbidities and widespread use of concomitant medications. The potential drug-drug interactions between these concomitant medications and DAA regimens differed, with the fewest potential interactions with sofosbuvir-based regimens.

Abstract
INTRODUCTION AND AIM Hepatitis patients usually present with comorbidities and polypharmacy which increases risk of potential drug-drug interactions (pDDIs). We explored frequency, levels, predictors, and clinical relevance of pDDIs in hospitalized hepatitis patients. MATERIAL AND METHODS Retrospective cohort study was used. Clinical profiles of 413 hepatitis patients were reviewed for pDDIs using Micromedex-DrugReax. Frequency, levels and clinical relevance of pDDIs were reported. Logistic regression analysis was used to calculate odds-ratios for predictors. RESULTS Of total 413 patients, pDDIs were reported in 55.2%. Major-pDDIs were found in 35% patients. Total 660 pDDIs were identified, of which, 304 (46%) were of major-severity and 299 (45%) of moderateseverity. Patient's profiles of top-10 major-pDDIs were presented with signs/symptoms such as fever, hepatomegaly, anorexia, jaundice, hypertension, tachycardia, bradycardia, & pedal edema; and abnormalities in labs such as electrolytes-level, alanine aminotransferase, blood urea nitrogen, bilirubin-level, & serum creatinine. Significant association was observed for the presence of pDDIs with > 9 prescribed medicines (p < 0.001), hospitalization of > 5 days (p = 0.03), and stroke as comorbidity (p = 0.05). Moreover, odds of exposure to major-pDDIs were significantly higher in patients taking > 9 prescribed medicines (p < 0.001), hospitalization of > 5 days (p = 0.002), and stroke as comorbidity (p = 0.002). CONCLUSION We observed hepatitis patients presented with a considerable number of clinically relevant pDDIs. Attention should be given to widespread major-pDDIs and their potential adverse outcomes. Clinically relevant parameters, such as labs and signs/symptoms should be monitored particularly in high risk patients having polypharmacy, prolong hospitalization, and stroke as comorbidity.

Abstract
INTRODUCTION Most direct-acting antivirals (DAAs) and psychotropic drugs are metabolized by or induct/inhibit CYP enzymes and drug transporters. Although they are frequently coadministered, the drug-drug interactions (DDIs) have been little studied. Therefore, the aim of this review is to describe the interactions between the approved DAA or combination regimens and the main psychoactive substances, including legal and illegal drugs of abuse. Areas covered: We performed a literature search on PubMed database on drug interactions with the currently available antivirals for hepatitis C and a review of the information on pharmacokinetics, metabolism, and drug interactions from www.hep-druginteractions.org and from all the Summary of Product Characteristics (SmPC). This review covers the DDI between the DAA regimens approved, such as simeprevir and sofosbuvir, paritaprevir, glecaprevir, voxilaprevir, ombitasvir, ledipasvir, daclatasvir and sofosbuvir, elbasvir and grazoprevir, sofosbuvir and velpatasvir, glecaprevir/pibrentasvir, sofosbuvir and velpatasvir, and main psychotropic agents. Expert Commentary: DAA regimens based on sofosbuvir combination usually have less DDI than protease inhibitor-based regimens. Among protease inhibitors regimens, new combinations, such as glecaprevir/elbasvir and grazoprevir/elbasvir, seemed to have less DDI than the combination POrD (paritaprevir/ombitasvir/ritonavir/dasabuvir). However, the analysis of each interaction is theoretical and further interaction studies would be necessary to confirm actual effect.

Abstract
Background The objective of the study was to evaluate the role of a clinical pharmacist in hepatitis C virus (HCV) treatment of patients living with HIV/HCV coinfection. Methods We conducted a descriptive study to quantify the functions of a clinical pharmacist in HCV treatment of patients living with HIV/HCV coinfection who were initiating HCV treatment at a publicly funded clinic between March 18, 2015 and September 15, 2016. The clinical pharmacist’s role was categorized into eight categories: 1) HCV prior authorization (PA) completion; 2) HCV medication adherence counseling; 3) HCV drug-drug interaction (DDI) counseling and screening; 4) HCV medication counseling regarding common adverse events (AEs); 5) HCV counseling regarding HCV treatment outcomes and risk of reinfection; 6) ordering laboratory tests and interpretation of HCV laboratory values; 7) HIV medication AE assessment; and 8) other (including refilling medications and management of other comorbidities). Results One hundred and thirty-five patients initiated treatment during this timeframe: 77.0% were males, 56.3% non-cirrhotic, 77.0% HCV treatment-naïve, 45.9% HCV genotype 1a, and 83.0% initiated on ledipasvir/sofosbuvir. The clinical pharmacist completed 150 PAs, counseled on HCV medication adherence in 79.2% of patients, conducted HCV DDI counseling and screening in 54.2%, and monitored HCV medication AEs in 54.2%. The clinical pharmacist counseled patients on HCV treatment outcomes and risk of reinfection in 53.1%, ordered laboratory tests in 44.8%, and reported and interpreted laboratory values in 44.8%. The clinical pharmacist assessed HIV medication AEs in 54.2% of patients and participated in other activities in 42.7%. Conclusion A clinical pharmacist’s expertise as part of a multidisciplinary care team facilitates optimal treatment outcomes and provides critical support in the management of DAA therapy in individuals living with HIV/HCV coinfection.

Abstract
BACKGROUND Direct-acting anti-viral agents have improved the treatment of chronic hepatitis C virus (HCV) infection, but this treatment is challenging for patients using co-medications because of potential drug-drug interactions. This study aimed to examine the comorbidities and co-medications of Japanese chronic HCV patients by age group, compared with a non-HCV patient population. METHODS This was a retrospective observational study using a hospital-based medical claims database. We extracted data of patients with chronic HCV aged ≥18 years, and age-, sex-, and hospital-matched patients without HCV, for the period from January 2015 to November 2016, and then examined chronic comorbidities, long-term co-medications, and medications prescribed at least once during the study period. RESULTS We analysed data from 128,967 chronic HCV patients and 515,868 non-HCV patients. The median age was 70 years, and 51.0% of patients were male. More chronic HCV patients than non-HCV patients (70.5% vs. 47.1%) had at least one comorbidity, and older patients had more comorbidities than younger patients. The most common comorbidities in chronic HCV patients were diseases of oesophagus, stomach and duodenum (41.7%), followed by hypertensive diseases (31.4%). Chronic HCV patients used co-medications more commonly than non-HCV patients, and older patients used more co-medications. The most common long-term co-medications in chronic HCV patients were proton pump inhibitors (14.0%), which were prescribed to 31.9% of chronic HCV patients at least once during the study period. CONCLUSIONS Patients with chronic HCV in Japan had more comorbidities than patients without chronic HCV regardless of age. Particularly older patients, who constitute the majority of the HCV patient population in Japan, commonly had multiple comorbidities and used co-medications. To optimise HCV treatment, physicians need to know the exact medication profiles of patients and take appropriate action to manage drug-drug interactions.

Abstract
OBJECTIVES To evaluate outcomes of a clinical pharmacist specialist (CPS)-managed hepatitis C virus (HCV) treatment clinic (HCVTC) in treating HCV-infected veterans with direct-acting antivirals (DAAs). METHODS We established a CPS-managed HCVTC under a collaborative practice agreement with our infectious disease physician (IDP). A total of 132 veterans were treated between November 1, 2014, and November 30, 2015. The CPS engaged in pretreatment screening, drug selection, patient education, medication counseling, drug therapy monitoring, drug utilization review, addressing issues on drug adherence, and routine and posttreatment follow-up of patients to assess sustained virologic response (SVR) after 12 weeks of treatment. RESULTS Of 132 patients managed by the CPS, 87 (66%) were treated with ledipasvir/sofosbuvir (LDV/SOF), 29 (22%) with paritaprevir/ritonavir/ombitasvir + dasabuvir (PrOD), and 16 (12%) with sofosbuvir (SOF)-based regimen. The corresponding regimens demonstrated a SVR rate of 92% (n = 80), 100% (n = 29), and 93.8% (n = 15), respectively. We achieved an SVR rate of 94% against HCV genotype 1 (GT-1) and 100% against GT-2 to GT-4. The overall SVR rate was 94% across regimens, showing 93% in treatment-naive patients and 96% in treatment-experienced patients, and 93% in noncirrhotic and 94% in compensated cirrhotic patients. The results were comparable to SVR data reported in pivotal trials for DAAs. CONCLUSION The results suggest that CPS could be effectively utilized in drug therapy management of HCV-infected patients treated with DAAs.

Abstract
BACKGROUND Many direct-acting antivirals (DAAs) have drug-drug interactions (DDIs) with the potential to affect efficacy and safety. OBJECTIVE To describe the incidence and severity of DDIs with DAAs identified by the hepatitis C virus (HCV) clinical pharmacist within a Veterans Affairs health care system. METHODS This single-center, retrospective cohort study evaluated patients with HCV treated with DAA therapy. Primary end points included the total number of identified DDIs, percentage of patients with at least 1 DDI, mean number of DDIs per patient, and the number of DDIs by severity category. Additional end points included characterization of interacting drugs, clinical consequence of interaction, intervention recommended, acceptance rate of actionable recommendations, and achievement of sustained virological response 12 weeks after treatment (SVR12). RESULTS A total of 300 patients were included. There were 554 identified DDIs, and 80.3% of patients had at least 1 DDI, with an average of 1.85 DDIs per patient; 76% of the DDIs identified were categorized as either a potentially clinically significant or critical interaction. The most common DDIs involved acid suppression agents (20%). Patient monitoring was the most commonly recommended intervention (59%), followed by dose modification of the interacting medication (30%). There was no difference in SVR12 between patients with at least 1 DDI compared with those with no DDIs (94.8% vs 95.8%; P = 0.73). There were a total of 227 actionable recommendations, with an acceptance rate of 84.1%. CONCLUSIONS This study suggests that DDIs are prevalent among patients treated with DAAs for HCV. A HCV clinical pharmacist can help optimize patient care by identifying DDIs and recommending interventions to providers.

Timing Strategies of Direct-Acting Antivirals and Biologics Administration in HCV-Infected Subjects with Inflammatory Bowel Diseases. Front Pharmacol 2017; 8:867.

Abstract
Background: In the last years, inflammatory bowel disease (IBD) and hepatitis C virus (HCV) infection management has completely changed. However, the role of direct-acting antivirals (DAAs) and the correct timing of antiviral drugs administration in IBD patients needing biologics has not been evaluated. Objective: To discuss the management of HCV-infected IBD patients, focusing our attention on the timing of DAAs administration subjects needing biologics. Methods: Relevant articles addressing HCV management in patients needing biologics were identified by searching from PubMed, MEDLINE and Scopus. Results: Three possible timing strategies were identified: (1) sequential strategy, meaning the choice of treating firstly the active IBD with biologics and then, once the acute phase has been controlled, treating the HCV infection; (2) concomitant strategy, that is the contemporaneous beginning of DAAs and biologics administration; (3) inverted sequential strategy-the administration of antiviral therapy before biologics in HCV-infected IBD patients. The potential pharmacological interactions between biologics and DAAs have also been reported. Conclusions: Clinical management of HCV-infected IBD patients remains a challenging problem for clinicians, especially in terms of timing choice. Recent published data about DAAs are very encouraging also in IBD patients. All strategies could be considered safe and effective. However, further data are immediately required in order to evaluate hepatic toxicity of novel immunosuppressive drugs in IBD.
