Abstract
Residential Juvenile Justice Services (JJS) facilities are located in every state and, in general, represent an underserved and diverse adolescent population. The JJS centers present an exciting and innovative opportunity for collaboration with colleges of nursing to initiate faculty practice sites. The University of Utah College of Nursing has been serving 5 JJS centers for 14 years and recently doubled its services to incorporate 10 different JJS Centers in the state of Utah. Each center offers a unique patient population and setting providing the student with an opportunity to learn health assessment and physical examination skills not typically presented in more traditional hospital or outpatient facilities. This type of community collaboration affords an opportunity for faculty practice, education, research, and service. An interprofessional focus enriches the experience.

Low-dose pegylated interferon-alpha-2a monotherapy in elderly and/or cirrhotic patients infected with hepatitis C virus genotype-2 or genotype-1 low level infection. Hepatol Res 2013; 43:702-8. [PMID: 23252609 DOI: 10.1111/hepr.12024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2012] [Revised: 11/09/2012] [Accepted: 11/11/2012] [Indexed: 01/01/2023]
Abstract
AIM Elderly and/or cirrhotic patients with hepatitis C virus (HCV) are at high risk of adverse effects during interferon therapy. The aim of the present study was to evaluate the efficacy, safety and predictive factors for sustained virological response (SVR) of low-dose pegylated interferon-α-2a (PEG IFN-α-2a) monotherapy in elderly and/or cirrhotic patients with HCV genotype-2 or genotype-1 low level infection. METHODS Sixty-four elderly (≥65 years) and/or cirrhotic patients with HCV genotype-2 or genotype-1 low level (<5 logIU/mL) infection underwent low-dose PEG IFN-α-2a (90 μg/week) monotherapy for 24 weeks. Sixty patients were available for efficacy assessment. RESULTS SVR was achieved in 78.3%. SVR rates according to genotype-1 low, genotype-2 low and genotype-2 high viral load were 90.0%, 87.1% and 57.9%, respectively. The discontinuation rate was 12.5%. PEG IFN-α-2a was interrupted or discontinued in four patients because of severe thrombocytopenia (<25 000/mm(3) ). The baseline platelet counts of all these patients were less than 70 000/mm(3) . On univariate analysis of factors contributing to SVR, significant differences were noted in viral load, platelet count, γ-glutamyltransferase, ferritin, α-fetoprotein level and rapid viral response (RVR). On multivariate analysis, RVR was the only independent factor (P = 0.010, odds ratio = 47.27). The positive and negative SVR-predictive values based on RVR were 95% and 82%, respectively. CONCLUSION Low-dose PEG IFN-α-2a monotherapy was effective and tolerable in elderly and/or cirrhotic patients with genotype-2 or genotype-1 low HCV level infection. However, a baseline platelet count of more than 70 000/mm(3) is needed for safety. RVR can predict SVR accurately.

Abstract
OBJECTIVE To determine the clinical, laboratory, serological and histologic characteristics of chronic hepatitis B virus carriers in our environment. MATERIAL AND METHODS A retrospective cohort study was performed that included chronic AgHBs carriers aged more than 13 years attending our service since January 2000. RESULTS A total of 474 patients were included. At diagnosis, 55.49% were men, with a mean age of 41.05±13.93 years. Alanine aminotransferase (ALT) levels were within the normal range in 57.17% of the patients, and 87.76% were AgHBe(-). Hepatitis C and D virus coinfection was found in 3.62% and 1.86%, respectively. Liver biopsy was performed in 31.22%; varying grades of inflammation-fibrosis were found in 63.51% and cirrhosis was found in 12.84%. Compared with AgHBe(-) patients, those who were AgHBe(+) were younger and had greater disease activity. This difference was statistically significant. Patients in the immunotolerant phase were the least numerous (5.26%), while AgHBe(-) patients with chronic HBV infection were the most numerous (48.32%). Patients in the immunoreactive phase showed greater histological involvement (16.67% cirrhosis). A familial history of chronic HBV was found in 21.52%. The percentage of non-Spanish patients increased in the last few years and accounted for 18.78%. CONCLUSION Chronic HBV infection in our environment occurs mainly in middle-aged persons. GPT values are normal in more than 50%, most are AgHBe(-), and approximately half are inactive carriers. The incidence of chronic infection has increased in the non-Spanish population in recent years.

Abstract
Background More than 50% of patients infected with chronic hepatitis C virus (HCV) do not respond to treatment with conventional interferon (IFN) combined with ribavirin (RBV). The aim of our study was to evaluate the effectiveness of retreatment with peginterferon alfa-2a or 2b (PEG-IFN 2a or 2b) concomitantly with RBV in patients with HCV genotype 2 and 3, which were non-responders or relapsers to initial treatment with IFN / RBV and to identify possible predictors of sustained virological response (SVR). Methods From September 2003 to March 2009 a cohort of 216 patients who had previously failed therapy with a regimen of standard interferon and ribavirin, were followed in a specialized service implemented in the Brazilian Unified Health System, Rio Grande do Sul. All patients were retreated with PEG-IFN 2a or 2b per week, associated with RBV, through oral route, with doses determined according to weight (1,000 mg if weight ≤ 75 Kg and 1,250 mg if ≥ 75 Kg) per day for 48 weeks. The HCV-RNA was tested by Polymerase Chain Reaction (PCR). Virological Response (VR) within 48 weeks and SVR in the 72 weeks was considered for evaluation of treatment efficacy. Analyses were performed in patients who received at least one dose of PEG-IFN. Results The SVR rate for non-responders to previous treatment was 34.4% and for relapsers was 50% (p = 0.031). As predictive factors that contribute to improve SVR, were identified the age (p = 0.005), to be relapsers to previous treatment (p = 0.023) and present liver biopsy examination Metavir F0-F2 (p = 0.004). In assessing the safety profile, 51 patients (23.6%) discontinued treatment prematurely. Conclusions This alternative retreatment for patients who have failed prior therapies for anti-HCV, has demonstrated promising SVR rate, provided that it includes a careful selection of patients with predictors of response and adverse events monitored.

Abstract
UNLABELLED The hepatitis C virus protease inhibitor telaprevir is an inhibitor of the enzyme cytochrome P450 3A, responsible for the metabolism of both cyclosporine and tacrolimus. This Phase I, open-label, nonrandomized, single-sequence study assessed the effect of telaprevir coadministration on the pharmacokinetics of a single dose of either cyclosporine or tacrolimus in two separate panels of 10 healthy volunteers each. In Part A, cyclosporine was administered alone as a single 100-mg oral dose, followed by a minimum 8-day washout period, and subsequent coadministration of a single 10-mg oral dose of cyclosporine with either a single dose of telaprevir (750 mg) or with steady-state telaprevir (750 mg every 8 hours [q8h]). In Part B, tacrolimus was administered alone as a single 2-mg oral dose, followed by a minimum 14-day washout period, and subsequent coadministration of a single 0.5-mg dose of tacrolimus with steady-state telaprevir (750 mg q8h). Coadministration with steady-state telaprevir increased cyclosporine dose-normalized (DN) exposure (DN_AUC(0-∞)) by approximately 4.6-fold and increased tacrolimus DN_AUC(0-∞) by approximately 70-fold. Coadministration with telaprevir increased the terminal elimination half-life (t(½)) of cyclosporine from a mean (standard deviation [SD]) of 12 (1.67) hours to 42.1 (11.3) hours and t(½) of tacrolimus from a mean (SD) of 40.7 (5.85) hours to 196 (159) hours. CONCLUSION In this study, telaprevir increased the blood concentrations of both cyclosporine and tacrolimus significantly, which could lead to serious or life-threatening adverse events. Telaprevir has not been studied in organ transplant patients; its use in these patients is not recommended because the required studies have not been completed to understand appropriate dose adjustments needed for safe coadministration of telaprevir with cyclosporine or tacrolimus, and regulatory approval has not been obtained.

Abstract
BACKGROUND Chronic hepatitis C patients with coexisting heart disease are often denied antiviral treatment due to safety concerns. However, this is not evidence-based. AIMS To evaluate safety and efficacy of pegylated interferon and ribavirin in chronic hepatitis C patients with heart disease. METHODS Patients with overt heart disease (ischaemic heart disease, prior mechanical heart valve replacement, chronic arrhythmias and cardiomyopathy) and chronic hepatitis C were treated with standard pegylated interferon/ribavirin doses for standard duration. Cardiovascular safety was monitored by electrocardiography, echocardiography and measurement of troponin and B-type natriuretic peptide. RESULTS Twenty-three patients (65.2% male, median age 57 years, 47.8% genotype 1) were treated. Three patients (13%) suspended treatment prematurely; 52% obtained sustained virological response, 39% relapsed, 9% were non-responders. No serious adverse event was observed. Post-treatment clinical examination, electrocardiography and echocardiography did not show any sign of progression of the pre-existing heart disease. CONCLUSIONS Treatment with pegylated interferon/ribavirin may be safely offered to carefully selected chronic hepatitis C patients with coexisting, clinically significant heart disease. In these patients, the outcome of antiviral treatment overlaps that observed in other patient subgroups.

Abstract
BACKGROUND AND AIM In the present study, we evaluated the safety and efficacy of combination therapy with pegylated interferon and ribavirin for treating chronic hepatitis C (CHC) patients aged 60 years and older. METHODS A total of 314 CHC patients, who were treated with combination therapy, were classified into three groups according to age: (i) younger than 50 years (n = 137); (ii) 50-59 years (n = 109); and (iii) 60 years or older (n = 68). The sustained virological response (SVR) and discontinuation rates were compared between the three groups. RESULTS Discontinuation of therapy due to adverse event was more frequent in the older patient groups: 1%, 5%, and 10% for the < 50-year, the 50-59-year, and the ≥ 60-year patient groups, respectively (P = 0.018). However, the older patient groups showed a SVR rate that was comparable to the SVR rates of the other age groups: 80%, 73%, and 75% for the < 50-year, 50-59-year, and ≥ 60-year- patient groups, respectively (P = 0.420). A multivariate analysis showed that the aspartate aminotransferase : platelet ratio index (APRI) was an independent predictor of an SVR. An SVR was achieved in 95% (19/20) of the elderly patients with an APRI < 0.80. CONCLUSIONS Although physicians must pay more attention to adverse events in the older patients, combination therapy can be considered for older patients, especially for patients with a low APRI.

Abstract
The complex functions of the liver in biosynthesis, metabolism, clearance, and host defense are tightly dependent on an adequate microcirculation. To guarantee hepatic homeostasis, this requires not only a sufficient nutritive perfusion and oxygen supply, but also a balanced vasomotor control and an appropriate cell-cell communication. Deteriorations of the hepatic homeostasis, as observed in ischemia/reperfusion, cold preservation and transplantation, septic organ failure, and hepatic resection-induced hyperperfusion, are associated with a high morbidity and mortality. During the last two decades, experimental studies have demonstrated that microcirculatory disorders are determinants for organ failure in these disease states. Disorders include 1) a dysregulation of the vasomotor control with a deterioration of the endothelin-nitric oxide balance, an arterial and sinusoidal constriction, and a shutdown of the microcirculation as well as 2) an overwhelming inflammatory response with microvascular leukocyte accumulation, platelet adherence, and Kupffer cell activation. Within the sequelae of events, proinflammatory mediators, such as reactive oxygen species and tumor necrosis factor-alpha, are the key players, causing the microvascular dysfunction and perfusion failure. This review covers the morphological and functional characterization of the hepatic microcirculation, the mechanistic contributions in surgical disease states, and the therapeutic targets to attenuate tissue injury and organ dysfunction. It also indicates future directions to translate the knowledge achieved from experimental studies into clinical practice. By this, the use of the recently introduced techniques to monitor the hepatic microcirculation in humans, such as near-infrared spectroscopy or orthogonal polarized spectral imaging, may allow an early initiation of treatment, which should benefit the final outcome of these critically ill patients.

Abstract
Hepatitis C continues to be a major public health problem affecting approximately 3% of the global population. According to the World Health Organization, an estimated 170 million people have chronic hepatitis C. Ten percent to 20% of those who are chronically infected with hepatitis C will progress to cirrhosis and 5% will develop hepatocellular carcinoma. Although the safety and efficacy of hepatitis C therapies have been studied extensively in patients between the ages of 18 and 65, patients who are older than 65 still remain an understudied and difficult-to-treat population. This review discusses the epidemiology, natural history, and treatment of chronic hepatitis C in older adults.

Abstract
Chronic liver disease and cirrhosis are the tenth leading causes of death in the United States and results in approximately 25,000 deaths annually. As life expectancy in developed countries has increased, so has the number of elderly patients who have liver disease. With an aging population and chronic liver disease becoming an increasingly significant cause of morbidity and mortality, the various causes for hepatitis will need to be evaluated and available treatments considered, even in elderly population. Common causes for hepatitis in elderly individuals include viral, autoimmune, and drug-induced hepatitis, but evidence for treatment of this population is limited. This article reviews the likely causes of hepatitis in elderly individuals and discusses evidence for treating this population.

Abstract
Acute and chronic hepatitis C virus (HCV) infection remains a serious health problem worldwide, however, there has been advancement in the treatment of HCV infection due to standard treatment using pegylated interferon and ribavirin. The literature indicates that therapy for HCV is becoming more individualized. In addition to considering genotype and viral RNA levels before treatment, achievement of an early virologic response (EVR) and a rapid virologic response (RVR) is now possible during therapy. Moreover, problem patients, such as non-responders, relapsers, HIV or HBV co-infected patients, patients with liver cirrhosis, and pre- or post-liver transplantation patients are an increasing fraction of the patients requiring treatment. This article reviews the literature regarding standard treatments and problem patients with acute and chronic HCV infection. It also includes discussion on contraindications and side effects of treatment with interferon and ribavirin, as well as new drug development.

Abstract
BACKGROUND/AIMS Although the antiviral and histological benefits of peginterferon/ribavirin therapy are well established, the effects on health-related quality of life (HRQOL) and sexual health are less certain. This study assessed HRQOL and sexual health in patients with advanced fibrosis or cirrhosis in the HALT-C Trial. METHODS Subjects completed SF-36 and sexual health questionnaires prior to and after 24 weeks of peginterferon/ribavirin therapy (n=1144). Three hundred and seventy-three (33%) subjects were HCV RNA negative at week 20 and continued therapy through week 48; 258 were seen at week 72. One hundred and eighty achieved sustained virological responses (SVR) and 78 relapsed. RESULTS At baseline, patients had poorer scores for all eight SF-36 domains compared to healthy controls. Patients with cirrhosis had lower HRQOL scores than those with bridging fibrosis, as did patients with higher depression scores. SVR patients had significant improvements in seven domains, whereas relapsers had significant worsening in one domain. Sexual scores improved in SVR patients and decreased in relapsers (p=0.03). In multivariate analyses, improvements in HRQOL and sexual scores were significantly associated with SVR but were less striking in patients with lower depression scores. CONCLUSIONS Achievement of SVR after peginterferon/ribavirin therapy improves HRQOL and sexual health in chronic hepatitis C patients with advanced fibrosis or cirrhosis.

Abstract
HCV infection is one of the leading causes of chronic liver disease worldwide,and it results in cirrhosis, liver failure, and HCC. As a result, hepatitis C cirrhosis has become the principal indication for liver transplantation. Ironically,HCV infection can be cured with available antiviral therapies, but only a minority of infected persons has ever been treated. The current standard of therapy isa combination of PEG-IFNalpha and ribavirin, which produces high rates of SVRs(absence of detectable HCV RNA at least 24 weeks after cessation of therapy):42% to 56% in genotype 1 and 75% to 84% in genotypes 2 and 3. Recent reports indicate that the less frequent genotypes 4, 5, and 6 also are responsive to combination therapy. Recommendations for treatment of conventional and special patient populations were reviewed in detail. Newer therapeutics that are entering clinical trials provide hope that SVRs may be possible in patients who are difficult to treat and in nonresponders to current therapy.

Abstract
Over 4 million people in the United States are chronically infected with hepatitis C virus (HCV), and, if untreated, over 20% of these will progress to more serious disease. Persons with severe mental illness (SMI) have markedly elevated rates of HCV infection, but treatment of persons with SMI and HCV has been controversial. Effective antiviral treatment is available, but side effects include depression and other neuropsychiatric symptoms. This article reviews the available data on neuropsychiatric side effects of interferon (IFN) treatment, discusses the limitations of the current research, and makes recommendations regarding HCV treatment in persons with SMI.

Abstract
Most of the older adults with chronic hepatitis C virus infection acquired the disease earlier in life. These patients often present with complications of liver disease, mainly cirrhosis and hepatocellular carcinoma. The burden of chronic hepatitis C virus infection in elderly persons is expected to increase significantly in the United States during the next 2 decades. It seems important that, for elderly patients with chronic hepatitis C, the risk-benefit of combination antiviral therapy consisting of pegylated interferon and ribavirin should be assessed on an individual basis. Assessment should be performed in all cases before considering treatment, and it should include evaluation of the degree of liver fibrosis by means of liver biopsy or, possibly, by means of noninvasive methods. Novel antiviral drugs that may have fewer adverse effects, such as protease inhibitors, may serve as potential alternatives. It is recommended that elderly patients (up to the age of 75 years) be included in randomized trials of chronic hepatitis C virus infection treatment.

Abstract
AIM: To compare the efficacy and safety of recombinant human IFN β-1a alone or in combination with ribavirin in treatment-naïve subjects with chronic hepatitis C.
METHODS: Open, randomized trial was performed in 6 Italian tertiary centers: 102 of the 108 patients screened were randomized to receive 6 MIU of recombinant human IFN β-1a subcutaneously daily for 24 wk, alone (Group 1, n = 51) or in combination with ribavirin 1 000 to 1 200 mg/d (Group 2, n = 51).
RESULTS: The end-of-treatment virologic response rate was 29.4% in Group 1 and 41.2% in Group 2 (non-significant). Twenty-four weeks after stopping therapy, sustained virologic response rate was 21.6% in Group 1 and 27.4% in Group 2 (non-significant). All subjects in Group 1 completed treatment, while two subjects in Group 2 stopped therapy due to treatment-related adverse events.
CONCLUSION: Recombinant human IFN β-1a, alone or in combination with ribavirin, has an excellent safety profile and, may represent an alternative for chronic hepatitis C patients who are unable to tolerate pegylated α-interferon.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is both prevalent and undertreated. OBJECTIVE To identify barriers to HCV treatment in primary care practice. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS A cohort of 208 HCV-infected patients under the care of a primary care physician (PCP) between December 2001 and April 2004 at a single academically affiliated community health center. MEASUREMENTS Data were collected from the electronic medical record (EMR), the hospital clinical data repository, and interviews with PCPs. MAIN RESULTS Our cohort consisted of 208 viremic patients with HCV infection. The mean age was 47.6 (+/-9.7) years, 56% were male, and 79% were white. Fifty-seven patients (27.4% of the cohort) had undergone HCV treatment. Independent predictors of not being treated included: unmarried status (adjusted odds ratio [aOR] for treatment 0.36, P=.02), female gender (aOR 0.31, P=.01), current alcohol abuse (aOR 0.08, P=.0008), and a higher ratio of no-shows to total visits (aOR 0.005 per change of 1.0 in the ratio of no-shows to total visits, P=.002). The major PCP-identified reasons not to treat included: substance abuse (22.5%), patient preference (16%), psychiatric comorbidity (15%), and a delay in specialist input (12%). For 13% of the untreated patients, no reason was identified. CONCLUSIONS HCV treatment was infrequent in our cohort of outpatients. Barriers to treatment included patient factors (patient preference, alcohol use, missed appointments), provider factors (reluctance to treat past substance abusers), and system factors (referral-associated delays). Multimodal interventions may be required to increase HCV treatment rates.

Abstract
Injection drug use has fueled the epidemic of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection in the United States. Nevertheless, drug dependence is among the main reasons that coinfected persons are not being treated for HCV infection. This report describes the development and progress of an HIV clinic program (funded by the Ryan White Comprehensive AIDS Resources Emergency Act) to deliver care for HCV infection to HIV-seropositive injection drug users. To optimize safety and adherence, pegylated interferon is directly administered to patients in the context of integrated addiction, psychiatric, and HIV and HCV therapy. Ribavirin is packed weekly in pill boxes for patients to take at home. Thus far, adherence to weekly visits for treatment with interferon has been 99%. No one has had to stop treatment for HCV infection because of ongoing drug use, addiction relapse or exacerbation, or psychiatric complications. Presented here is a work in progress, rather than a finished research project or definitive model of care.

Abstract
OBJECTIVE Our objective was to quantify the pharmacokinetics of methadone and the pharmacokinetics and pharmacodynamics of peginterferon alfa-2a (40 kd) in patients with chronic hepatitis C undergoing methadone maintenance therapy. METHODS Adults with chronic hepatitis C who had been receiving a consistent methadone maintenance regimen for at least 3 months were eligible for this open-label, multicenter, nonrandomized drug interaction study. All patients received 180 microg subcutaneous peginterferon alfa-2a once weekly for 4 weeks and continued their methadone regimen. Serial blood samples were collected at baseline and immediately before and for up to 168 hours after study drug administration for the purposes of quantifying methadone and peginterferon alfa-2a serum concentrations, measuring serum 2',5'-oligoadenylate synthetase activity, and determining hepatitis C virus ribonucleic acid levels. RESULTS Twenty-four patients were enrolled. Methadone exposure, as measured by maximum serum concentration (C(max)) and area under the concentration-time curve (AUC) normalized to a 100-mg/d dose, after 4 doses of peginterferon alfa-2a increased by 10% to 15% when compared with baseline. The week 4/baseline ratio of the mean C(max) was 1.11 (90% confidence interval [CI], 1.02-1.22), and for AUC from time 0 to 24 hours, the week 4/baseline ratio was 1.15 (90% CI, 1.08-1.23). The mean accumulation ratios (week 4/first dose) for C(max) and AUC from time 0 to 168 hours of peginterferon alfa-2a were 2.1 and 2.3, respectively. CONCLUSIONS Peginterferon alfa-2a does not appreciably alter the pharmacokinetics of methadone.

Abstract
The management of chronic viral hepatitis has changed significantly with the availability of effective antiviral agents. There is now a high probability that timely intervention can arrest development of cirrhosis, thereby preventing mortality from portal hypertension, liver failure and liver cancer. This two-part review discusses the implications of this new era of antiviral therapy for physicians. The present review is about chronic hepatitis C virus (HCV); a similar review that considers the treatment of hepatitis B virus will be published in a later issue of the Internal Medicine Journal. Chronic HCV infection is common, but fibrotic progression of liver disease is slow and variable; many infected persons never develop cirrhosis. Case selection for antiviral therapy is crucial. The most effective therapy is a pegylated (long-acting) interferon with ribavirin. Sustained viral response (SVR) (absent viraemia 6 months after completing treatment) can be obtained in 40-60% of individuals infected with genotype 1 and in approximately 67% with genotype 4 after 12 months of treatment. Response rates are higher (75-85%) with genotypes 2 and 3 after only 6 months of treatment. Late relapse is negligible after SVR. This viral cure reverses hepatic fibrosis, reduces the risk of liver failure and of hepato-cellular carcinoma. Combination therapy requires a supportive setting to minimize the impact of side-effects and maximize therapeutic effectiveness. Overall management of HCV-infected persons must also embrace measures to improve quality of life by preventing or dealing with psychosocial issues and advocating lifestyle changes to counter comorbidity from alcohol, central obesity and insulin resistance. These latter factors favour fibrotic disease progression, complications of cirrhosis (such as hepatocellular carcinoma) and development of type 2 diabetes mellitus, as well as eroding the chances of SVR with antiviral therapy.
