Epoetin alfa therapy for anaemia in HIV-infected patients: impact on quality of life

To evaluate the effect of epoetin alfa on the quality of life (QOL) of HIV-infected patients in the community setting, 221 anaemic (haemoglobin < or = 11 g/dl) HIV-positive patients from community-based treatment centres and physicians' offices were treated with epoetin alfa (100-300 units/kg subcutaneously 3 times a week) in a 4-month, open-label, non-randomized, phase IV trial. Epoetin alfa therapy significantly (P<0.01) increased and maintained haemoglobin levels (mean increase=2.5 g/dl; n=207); the improvement in haemoglobin levels was independent of changes in CD4+ cell counts. Transfusion requirements were also significantly reduced from 20% to 5% of patients (P<0.01). Mean total QOL score measured by the Functional Assessment of HIV Infection (FAHI) scale and Physical Well-Being subscale score improved significantly (P<0.05). QOL improvements associated with increases in haemoglobin were independent of changes in CD4+ counts and baseline anaemia severity. Adverse events observed during epoetin alfa therapy were consistent with HIV disease and not likely due to the drug. Epoetin alfa therapy should be considered a treatment option for HIV-infected patients with mild-to-moderate anaemia.     

Once-weekly epoetin alfa improves quality of life and increases hemoglobin in anemic HIV+ patients

This prospective, open-label, multicenter trial evaluated the effects of once-weekly (qw) epoetin alfa on quality of life (QOL) and hemoglobin (Hb) levels in anemic human immunodeficiency virus (HIV)-infected adult receiving antiretroviral therapy. A total of 650 patients with Hb < or = 11 g/dl received epoetin alfa 40,000 U qw subcutaneously, with dose escalation to 60,000 qw if Hb increase was <1 g/dl after 4 weeks. The linear Analog Scale Assessment (LASA) overall QOL score, LASA energy score, and LASA activity score each significantly improved from baseline to final measurement (p < 0.0001 for each parameter). Improvements in the Medical Outcomes Study (MOS)-HIV physical and mental health summary scores were also significant (p < 0.0001), and coincided with Hb increases. Mean Hb increased from baseline to final measurement by 2.5 g/dl (95% CI: 2.3, 2.6 g/dl; p < 0.0001). Objective hematological response rate, defined as a > or = 1 g/dl Hb increase from baseline to week 8, was 86%. Hemoglobin increased significantly in all subgroups of race, zidovudine use, CD4+ cell count, and viral load. Once-weekly epoetin alfa was well tolerated. Once-weekly epoetin alfa is effective in improving QOL and Hb measures.     

Health-related quality of life in HCV-infected patients

In March 2007, a systematic review was conducted of published research on the topic of health-related quality of life (HRQOL) in patients with hepatitis C virus (HCV) infection. Recent studies indicate that significant decrements in HRQOL exist for patients with HCV under many circumstances and arise from multiple sources. Future research is needed on finding interventions that address all sources of reduced HRQOL in patients with HCV, whether or not they are on treatment. It is also important to continue work on identifying the direct mechanisms behind lower HRQOL in patients with HCV.     

Epoetin alfa maintains ribavirin dose in HCV-infected patients: a prospective, double-blind, randomized controlled study

BACKGROUND & AIMS: Combination therapy with interferon alpha (IFN-alpha) and ribavirin (RBV) or pegylated IFN-alpha (PEG-IFN-alpha)/RBV for chronic hepatitis C virus (HCV) infection often causes anemia, prompting RBV dose reduction/discontinuation. This study assessed whether epoetin alfa could maintain RBV dose, improve quality of life (QOL), and increase hemoglobin (Hb) in anemic HCV-infected patients. METHODS: HCV-infected patients (n = 185) on combination therapy who developed anemia (Hb < or = 12 g/dL) were randomized into a U. S. multicenter, placebo-controlled, clinical trial of epoetin alfa, 40,000 U subcutaneously, once weekly vs. matching placebo. The study design used an 8-week, double-blind phase (DBP) followed by an 8-week, open-label phase (OLP), in which placebo patients were crossed over to epoetin alfa. RESULTS: At the end of the DBP, RBV doses were maintained in 88% of patients receiving epoetin alfa vs. 60% of patients receiving placebo (P < 0.001). Mean QOL scores at the end of the DBP improved significantly on all domains of the Linear Analog Scale Assessment (LASA) and on 7 of the 8 domains of the Short Form-36, version 2 (SF-36v2). Mean Hb increased by 2.2 +/- 1.3 g/dL (epoetin alfa) and by 0.1 +/- 1.0 g/dL (placebo) in the DBP (P < 0.001). Similar results were demonstrated in patients who switched from placebo to epoetin alfa in the OLP. Epoetin alfa was well tolerated; the most common adverse effects were headache and nausea. CONCLUSIONS: Epoetin alfa maintained RBV dose and improved QOL and Hb in anemic HCV-infected patients receiving combination therapy.     

Quality of life improvements in dialysis patients receiving darbepoetin alfa

Short-acting hematopoietic agents can improve the quality of life (QOL) of hemodialysis patients, but questions remain regarding the domains of QOL affected, the relative importance of initial and final hemoglobin (Hb) concentrations, and the use of long-acting hematopoietic agents. We measured Hb concentrations and QOL in 487 hemodialysis patients who were switched from treatment with recombinant human erythropoietin to treatment with darbepoetin alfa. QOL was measured with the Japanese-language version of the SF-36, at the start of therapy with darbepoetin alfa and again 7-14 weeks later. We examined changes in QOL over time in the group as a whole, and in subgroups stratified by the change in Hb concentration. We also studied relationships between the final Hb concentration achieved and the magnitude of change in QOL. QOL scores increased significantly in all SF-36 domains except Social Functioning. The greatest increases were in vitality and in the two role-functioning domains. The magnitude of the increase in Hb concentration was related to the magnitude of the increase in QOL for only one subscale: Vitality. Patients with higher final Hb concentrations also had greater increases in Vitality scores. Hematopoiesis induced by darbepoetin alfa is associated with increased vitality and may also be associated with improved role functioning. Vitality increased significantly only in those patients with the greatest increases in Hb concentration and in those with higher final Hb concentrations.     

Efficacy of epoetin alfa administered every 2 weeks to maintain hemoglobin and quality of life in anemic HIV-infected patients

Anemia, a common hematological abnormality in HIV, contributes to decreased quality of life (QOL). This study assessed once-every-2-week epoetin alfa on maintaining QOL and hemoglobin (Hb) in anemic HIV-infected patients in a 24-week, open-label, multicenter study. HIV-infected patients (Hb < or =12 g/dl) received epoetin alfa 40,000 units subcutaneously once weekly, until reaching Hb > or =13 g/dl. Patients then entered a maintenance phase (MP), in which epoetin alfa was administered every other week or at longer intervals. The trial objectives were to determine if QOL, as measured by the Medical Outcomes Study-HIV (MOS-HIV) general health perceptions (GHP) domain and Hb, was maintained. Safety was also assessed. A total of 292 patients were enrolled (72% on HAART). Mean baseline laboratory values were Hb = 10.8 g/dl, CD4(+) count = 280 cells/microl, and HIV RNA = 51,867 copies/ml. In all, 81% of patients reached Hb > or =13 g/dl and 92% reached Hb > or =12 g/dl. QOL was maintained from the beginning (GHP = 44.2 points) to the end of MP (GHP = 43.4 points) with every other week or longer dosing. Mean Hb at the beginning of MP was 13.4 +/- 0.5 g/dl and was 12.8 +/- 1.4 g/dl at study end. Epoetin alfa was well tolerated; adverse events were consistent with those reported in previous studies of epoetin alfa in HIV-infected patients. Although the clinical approach tested in this study is not consistent with current prescribing recommendations, the results confirm the efficacy of prolonged dosing intervals (every 2-4 weeks) in maintaining optimal Hb levels and QOL in anemic HIV-infected patients.     

Health-related quality of life of HIV-infected adults receiving combination antiretroviral therapy in Addis Ababa

Health-related quality of life (HRQoL) is an important outcome measure among HIV-infected patients receiving combination antiretroviral therapy (cART), but has not been studied extensively in resource-limited settings. Insight in the predictors or correlates of poor HRQoL may be helpful to identify patients most in need of additional support and to design appropriate interventions. A cross-sectional study was conducted between September 2012 and April 2013 in 10 healthcare facilities in Addis Ababa, Ethiopia. Patients who were at least 6 months on cART were randomly selected and individual patient data were retrieved from medical records. HRQoL was measured by the WHOQoL-HIVBREF, depressive-symptoms by the Kessler-6 scale, and stigma by the Kalichman internalized AIDS-related stigma scale. Multivariate linear regression analysis was carried-out to examine associations between HRQoL and the other variables. A total of 664 patients (response-rate 95%) participated in the study. A higher level of depressive-symptoms was most strongly and consistently associated with a lower HRQoL, both in terms of the magnitude of the relationship and in the number of HRQoL domains associated with it. Also, a higher level of HIV-stigma was associated with a lower HRQoL except for the physical domain, while obtaining sufficient nutritious food and job opportunity were associated with a better HRQoL except for the spiritual and social domains, respectively. Demographics, clinical, and treatment characteristics yielded few significant associations with HRQoL. Our study findings suggest that interventions to improve HRQoL should focus on reducing depressive-symptoms and HIV-stigma, and on enhancing food security and job opportunity.     

Epoetin alfa treatment for acute anaemia during interferon plus ribavirin combination therapy for chronic hepatitis C

Summary.  Infection with the hepatitis C virus (HCV) remains chronic in 75% of infected individuals, in whom it can cause liver inflammation and progressive fibrosis leading to cirrhosis in 20% of patients. A sustained viral response (SVR) to HCV therapy, i.e. undetectable plasma HCV RNA 6 months after the end of treatment, leads to permanent eradication of the virus in 98.3% of patients. The current treatment of choice is combination therapy with pegylated interferon alfa (PEG-IFN alfa), 2a or 2b, and ribavirin (RBV), which achieves an SVR in 54–56% of patients. In patients with HCV genotype 1, RBV doses of 1000–1200 mg/day are associated with a higher SVR than 800 mg/day (51 vs 40%). However, RBV also causes dose-dependent reversible haemolytic anaemia that, in combination with the myelosuppressive effects of PEG-IFN, results in a mean drop in haemoglobin (Hb) level of 3.7 g/dL within 4 weeks. Conventionally, this acute anaemia has been managed with RBV dose reductions. However, this may result in a decreased SVR rate. Alternatively, this anaemia can be managed with administration of epoetin alfa at 40 000 IU once weekly. In a randomized placebo-controlled trial, treatment with epoetin alfa has been shown to raise Hb levels and maintain RBV doses. Furthermore, the increase in Hb level was associated with improved quality of life. Anaemia in patients treated with interferon plus RBV combination therapy can be managed effectively and safely with once weekly epoetin alfa without sacrificing optimal dosing of RBV.     

Cognitive-behavioral therapy improves the quality of life of patients with acromegaly

Background

The delayed diagnosis, altered body image, and clinical complications associated with acromegaly impair quality of life.

Purpose

To assess the efficacy of the cognitive-behavioral therapy (CBT) technique “Think Healthy” to increase the quality of life of patients with acromegaly.

Methods

This non-randomized clinical trial examined ten patients with acromegaly (nine women and one man; mean age, 55.5?±?8.4 years) from a convenience sample who received CBT. The intervention included nine weekly group therapy sessions. The quality of life questionnaire the 36-Item Short Form Survey (SF-36) and the Beck Depression Inventory (BDI) were administered during the pre- and post-intervention phases. The Wilcoxon signed-rank test was performed to assess the occurrence of significant differences.

Results

According to the SF-36, the general health domain significantly improved (d′??=???0.264; p?=?0.031). The mental health domain improved considerably (d′??=???1.123; p?=?0.012). Physical functioning showed a non-significant trend toward improvement (d′??=???0.802; p?=?0.078), although four of the five patients who showed floor effects improved and remained at this level. Regarding emotional well-being, five patients showed floor effects and four improved, and the condition did not change among any of the four patients who showed ceiling effects. No significant changes were found with regard to the other domains. No significant differences in the BDI were found before or after the intervention.

Conclusion

The technique presented herein effectively improved the quality of life of patients with acromegaly with different levels of disease activity, type, and treatment time.

     

Oral budesonide therapy improves quality of life in patients with collagenous colitis

Introduction Collagenous colitis is an idiopathic microscopic colitis characterised by watery diarrhoea. The impact of collagenous colitis on quality of life has not been assessed. Our aim was to assess quality of life in patients with this condition and compare the effect of treatment with budesonide capsules or placebo on this parameter.Methods Patients with chronic diarrhoea and histologically-proven collagenous colitis were randomised to receive either budesonide controlled-release capsules (Entocort capsules, AstraZeneca, Lund, Sweden), 9 mg/day, or placebo for 6 weeks. Quality of life was measured using the validated Gastrointestinal Quality of Life Index (GIQLI) at baseline and after 6 weeks. With the GIQLI, scores range from 0 to 144, with higher scores representing better quality of life.Results Complete quality of life assessment was available in 29 patients (budesonide: n=17; placebo: n=12). At baseline, quality of life was low in patients with collagenous colitis (mean 76). After 6 weeks of treatment, the mean GIQLI score increased significantly in the budesonide group (from 67 to 92, p<0.001), but remained unchanged in the placebo group (86–88). The mean score of the dimensions symptoms (p=0.001), emotional functioning (p=0.003) and physical functioning (p=0.017) increased significantly in the budesonide group compared with the placebo group. A significantly larger proportion of patients in the budesonide group experienced improved stool consistency (p<0.01) and a significant reduction in the mean stool frequency compared with those in the placebo group (p<0.01).Conclusion Quality of life is seriously reduced in patients with collagenous colitis. Six-week treatment with oral budesonide controlled-release capsules significantly improves quality of life and clinical symptoms compared with placebo in these patients.     

Impact of lipoatrophy on quality of life in HIV patients receiving anti-retroviral therapy

Metabolic and morphological side-effects occur in HIV-infected individuals receiving anti-retroviral treatment (ART). Peripheral fat loss that occurs particularly in the face, limbs and/or buttocks is referred to as lipoatrophy and has been found to be highly stigmatizing and to adversely impact the health-related quality of life (HRQL). Consumer Health Sciences Survey data collected between November 2003 and January 2006 were utilized to evaluate the impact of lipoatrophy on the HRQL in HIV-infected individuals receiving ART. This was evaluated using analysis of variance with item scores and mental component summary (MCS) and physical component summary (PCS) scores from the Medical Outcomes Trust questionnaire, SF-8 as dependent variables and lipoatrophy as the independent variable controlling for baseline age, sex and ethnicity. Clinical meaningfulness (mean difference divided by population standard deviation, delta/sigma) of differences between the groups with and without lipoatrophy was also evaluated. A cohort of 1124 subjects with at least six months of ART was selected based on the availability of data on whether or not lipoatrophy was present. Subjects were primarily male (80%), between the ages of 30 and 60 years (90%), Hispanic (37%) and about 25% each of African American and White. Overall, prevalence of lipoatrophy in this cohort of HIV patients was 18.9%. Statistically significant (p<0.001) differences in quality of life (as measured by SF-8 individual item scores and MCS and PCS scores) were observed between the two groups. The differences between the groups in item and summary scores were clinically meaningful in the small to near medium range (0.28-0.43). HIV-infected patients already experience a considerable deficiency in HRQL compared to general population; this study demonstrates that lipoatrophy further enhances that negative impact on HRQL.     

Once-weekly epoetin alfa improves anemia and facilitates maintenance of ribavirin dosing in hepatitis C virus-infected patients receiving ribavirin plus interferon alfa

OBJECTIVE: The aim of this study was to determine the efficacy of epoetin alfa in alleviating anemia and minimizing ribavirin (RBV) dose reductions in patients with chronic hepatitis C virus (HCV) infection receiving combination RBV/interferon alfa (IFN) therapy. METHODS: HCV-infected patients who had Hb levels of 12 g/dl or less during the first 24 wk of combination RBV/IFN therapy (n=64) were randomized to treatment with epoetin alfa (40,000 units) s.c. q.w. or to standard of care (SOC) for anemia management (RBV dose reduction or discontinuation, transfusions). Primary and secondary efficacy endpoints were changes in Hb level and RBV dosage, respectively, from baseline to week 16 of epoetin alfa therapy.Based on intent-to-treat analysis, the mean changes from baseline Hb levels at week 16 were +2.8 g/dl for epoetin alfa versus +0.4 g/dl for SOC (p<0.0001), and the mean changes in RBV dosage were -34 mg/day for epoetin alfa versus -146 mg/day (p=0.060) for SOC. The mean Hb level at week 16 in the epoetin alfa group (13.8 g/dl) was significantly (p<0.0001) higher than that of the SOC group (11.4 g/dl). At week 4 and subsequently, significantly more patients in the epoetin alfa group did not have RBV dosage reductions (p<0.011). At study end, 83% of epoetin alfa-treated patients maintained RBV dosages of at least 800 mg/day, compared with 54% of patients receiving SOC (p=0.022). Epoetin alfa was well tolerated. CONCLUSIONS: In anemic HCV-infected patients treated with RBV/IFN, epoetin alfa increases Hb levels and maintains RBV dosing. Based on these results, epoetin alfa seems to be promising in the treatment of HCV treatment-related anemia. Further research is warranted to determine the potential impact on outcomes, including quality of life and sustained viral response rate.     

Evaluation of health-related quality of life in low-income patients with COPD receiving long-term oxygen therapy

STUDY OBJECTIVE: To assess health-related quality of life (HRQL) in a low-income population of patients with hypoxemia and COPD receiving long-term oxygen therapy (LTOT). DESIGN: Cross-sectional study. SETTING: Large, tertiary care, university teaching hospital. Patients or participants: Thirty-six patients with COPD requiring LTOT (mean age, 63.5 years; mean FEV(1), 32.1% of predicted; PaO(2), 50.2 mm Hg) and 33 control subjects with COPD but no severe hypoxemia (mean age, 63.1 years; FEV(1), 35.7%; PaO(2), 66.5 mm Hg). INTERVENTIONS: Patients underwent pulmonary function testing to assess physiologic function and the degree of respiratory impairment. A baseline dyspnea index (BDI) was used to determine levels of dyspnea, and a 6-min walk test was performed to evaluate physical performance and exercise capacity. The St. George Respiratory Questionnaire (SGRQ) and the Medical Outcomes Study Short-Form 36-item questionnaire (SF-36) were used to assess health status and HRQL. Measurements and results: The scores on the SGRQ and SF-36 indicated severe impairment. Patients receiving LTOT showed a trend toward worse scores on most dimensions of the SGRQ and SF-36, but differences between groups were only statistically significant for the physical functioning and social functioning dimensions of the SF-36. Dyspnea, as measured by the BDI, significantly correlated with all questionnaire domains except the SF-36 pain index. CONCLUSIONS: The HRQL of these low-income patients with COPD was markedly impaired, with more pronounced impairment in those receiving LTOT. The severity of dyspnea was a significant predictor of various components of quality of life in these patients.

Epoetin alfa. Clinical evolution of a pleiotropic cytokine

Recombinant human erythropoietin (epoetin alfa) has been used in clinical settings for more than a decade. Its indications have expanded considerably from its original use as hormone therapy in the treatment of anemia in adults with chronic kidney disease. Since the introduction of epoetin alfa, a greater understanding of anemia pathophysiology and the interactions of erythropoietin, iron, and erythropoiesis has been elucidated. Anemia is now independently associated with increased mortality and disease progression. Potential survival benefits associated with correction of anemia in various patient populations are leading to consideration of earlier, more aggressive treatment of mild to moderate anemia with epoetin alfa. Moreover, this agent's therapeutic use may extend beyond currently accepted roles. Epoetin alfa is undergoing evaluation with promising results in a variety of new clinical settings, including anemia associated with congestive heart failure, ribavirin-interferon alfa treatment of hepatitis C virus infection, and critical illness. Preclinical studies also have established erythropoietin and its recombinant equivalent to be a pleiotropic cytokine with antiapoptotic activity and neuroprotective actions in the central nervous system. The therapeutic potential of epoetin alfa appears yet to be fully realized.     

Infliximab improves quality of life in patients with Crohn's disease

OBJECTIVE: The aim of this study was to assess the effect of infliximab on quality of life in patients with active Crohn's disease (CD) inadequately responsive to concomitant therapies. METHODS: We examined responses to the Inflammatory Bowel Disease Questionnaire (IBDQ) from patients enrolled in a previously reported, randomized, placebo-controlled study. Patients with active CD received a single intravenous infusion of either placebo or infliximab 5, 10, or 20 mg/kg. Most patients received stable doses of mesalamine, corticosteroids, azathioprine, or 6-mercaptopurine throughout the study. Changes from baseline in overall IBDQ score and individual dimensions at 4 weeks postinfusion were compared. RESULTS: Patients treated with infliximab had a significantly larger improvement in overall IBDQ score than those treated with placebo at 4 weeks (p < 0.001). Infliximab-treated patients also had larger improvements in all IBDQ dimensions: bowel (p = 0.007), social (p = 0.002), emotional (p < 0.001), and systemic (p < 0.001). A significantly larger proportion of infliximab-treated patients reported having normal or near-normal frequency of bowel movements in the past week (p < 0.001), full or a lot of energy (p = 0.019), and no or hardly any difficulty doing leisure or sports activities (p = 0.011), and being extremely or very satisfied with their personal life (p = 0.046). They also significantly differed in responses regarding fatigue, frustration, ability to work, general well-being, depression, anxiety, and anger resulting from bowel problems. CONCLUSIONS: These results indicate that infliximab significantly improved quality of life in patients with active CD, increasing their ability to work and participate in leisure activities, and decreasing feelings of fatigue, depression, and anger.     

Haematological support during peg-interferon therapy for HCV-infected haemophiliacs improves virological outcomes

Hepatitis C virus-infected haemophiliacs are traditionally under represented in international treatment studies thus data assessing response to pegylated-interferon (peg-IFN) and ribavirin (RBV) in HCV mono-infected or HCV/HIV co-infected haemophiliacs are few. Since 2001, 37 haemophiliac patients have received peg-IFN and RBV according to centre-based investigator initiated protocols. Primary end points were: early virological response (EVR); end of treatment response (EOTR) and sustained virological response (SVR). An intention-to-treat analysis was used. Secondary end points were adverse events, haemopoietic stem cell growth factor use, therapy discontinuations and dose reductions. Hepatitis C virus mono-infection group (Mono-I) numbered 20 (60% genotype 1). HCV/HIV co-infected group (Co-I) numbered 17 (59% genotype 1/4). Primary end points were: EVR 76%, EOTR 70% and SVR 43%. Comparison of Mono-I to Co-I demonstrated: EVR rates of 70% and 82%, respectively; EOTR rates of 65% and 76%, respectively, and SVR rates of 35% and 53%, respectively. SVR rates genotype 1/4 group - 17% (Mono-I) vs. 30% (Co-I); SVR rates genotype 2/3 group - 63% (Mono-I) vs. 86% (Co-I). Therapy discontinuations: six of 20 (30%) Mono-I vs. three of 17 (18%) Co-I. Dose reductions: two of 20 (10%) Mono-I vs. zero of 17 Co-I. Haematological support factor use: one of 20 (5%) Mono-I vs. four of 17 (23.5%) Co-I. Virological outcomes to peg-IFN and RBV in HCV-infected haemophiliacs are comparable to published data relating to other HCV-infected cohorts. Good virological outcomes can be achieved in HIV co-infected haemophiliacs particularly when growth factors are used to facilitate full dosing of peg-IFN and RBV.     

Epoetin beta therapy in patients with solid tumours

Anaemia is a common occurrence in patients with cancer, resulting in symptoms such as fatigue that have a profound impact on quality of life. Anaemia is also associated with poor treatment outcome and overall survival. Epoetin beta, a recombinant human erythropoietin that has the same structure and function as the endogenous hormone, is an effective and safe treatment of cancer-related anaemia. Various studies in patients with solid tumours have shown that this agent effectively increases haemoglobin levels and reduces the need for emergency blood transfusions regardless of the type of concomitantly administered chemotherapy. Epoetin beta also improves the quality of life of anaemic patients with cancer, decreasing fatigue and improving the ability to perform usual daily activities. In addition, epoetin beta prevents severe anaemia and reduces transfusion requirements in patients with a high-risk of developing anaemia during chemotherapy, such as those receiving platinum-based regimens. A meta-analysis of epoetin beta trials showed that epoetin beta has no negative impact on survival or thrombosis-related survival and may reduce the risk of tumour progression in patients with solid or lymphoid malignancies. Another study has shown epoetin beta to be equally effective when administered once weekly or three times weekly. Therefore, epoetin beta offers an effective, safe and convenient therapy for the management of anaemia in patients with cancer.     

Adherence to therapy: Challenges in HCV-infected patients

Although clinicians recognize the importance of adherence to HCV therapy, little research has been conducted to determine actual adherence rates or predictors of adherence in this population. Adherence is a challenge in the HCV-infected individual because of the complexities of the drug regimen, side effects from the medication, frequency of clinical monitoring, variable response to therapy, and potential complications. However, because of the time-limited nature of the current medication therapies, multidisciplinary and multifactoral interventional strategies may be designed to positively influence adherence rates and, ultimately, treatment outcomes in this patient population.
