Factors associated with patient satisfaction with antiretroviral therapy in Japan: A cross-sectional, multicenter study. J Infect Chemother 2024; 30:746-751. [PMID: 38365064 DOI: 10.1016/j.jiac.2024.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 02/06/2024] [Accepted: 02/11/2024] [Indexed: 02/18/2024]
Abstract
BACKGROUND Current antiretroviral therapy (ART) regimens are highly effective; therefore, to differentiate between various regimens, considering patient-reported outcomes is essential. This study aimed to assess patient satisfaction with their current ART regimens and investigate factors associated with the Human Immunodeficiency Virus Treatment Satisfaction Questionnaire: Status (HIVTSQs) score. METHODS This cross-sectional, multicenter study was conducted in Japan between April and December 2021. Patient-reported satisfaction with ART was assessed using the Japanese version of the HIVTSQs. Binary logistic regression was used to identify factors associated with a low total HIVTSQs score. RESULTS A total of 679 patients completed the questionnaire. The median total HIVTSQs score was 58 (interquartile range: 52.5-64). In the multivariable logistic regression analyses, a total HIVTSQs score in the lowest quartile (indicating low satisfaction) was independently associated with twice- or thrice-daily regimens compared with single-tablet, once-daily regimens (adjusted odds ratio: 2.80, 95% confidence interval: 1.29-6.06, p = 0.009) and depression (adjusted odds ratio: 2.30, 95% confidence interval: 1.32-4.01, p = 0.003). CONCLUSIONS Satisfaction with the current ART regimen was high. Depression and twice- or thrice-daily ART regimen were associated with low HIVTSQ. Switching to a single-tablet, once-daily regimen may improve patient satisfaction in patients receiving twice- or thrice-daily regimens.

Guan M, Guan H. Associations between treatment burden, self-reported treatment qualities, antiretroviral therapy obtainment, and health-related quality of life among Ugandan PLWH. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2023; 21:25. [PMID: 37041641 PMCID: PMC10091552 DOI: 10.1186/s12962-023-00434-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 03/17/2023] [Indexed: 04/13/2023] Open
Abstract
BACKGROUND Understanding related risk factors of health-related quality of life (HRQoL) could avoid treatment failure and provide an insight of personalized treatment approach among people living with HIV/AIDS (PLWH). The objective of this study was to identify factors associated with self-reported treatment qualities and domains of health-related quality of life (HRQoL) among PLWH in Uganda. METHOD Data were from "Life on antiretroviral therapy: People's adaptive coping and adjustment to living with HIV as a chronic condition in Wakiso District, Uganda" in English. The World Health Organization Quality of Life Brief Version (WHOQOL-BREF) questionnaire was used to assess the HRQoL of 263 PLWH in the sample. Considering variance inflation factors, multiple regression analyses were performed to assess the associations between demographic factors, ART obtainment, treatment burden, and self-reported treatment qualities, associations between demographic factors, self-reported treatment qualities, and HRQoL, and association between ART obtainment and HRQoL. Controlling for the confounding effects, several regression anatomies were employed to explore the associations between self-reported treatment qualities and six domains of HRQoL. RESULTS In the sample, the geographical distribution were urban (5.70%), semi-urban (37.26%), and rural (57.03%). 67.30% of the participants were females. The mean age of the sample was 39.82 years (standard deviation = 9.76) ranging from 22 to 81 years. Multiple logistic regressions reported statistically significant associations of distance to ART facility with self-reported quality of services, advice, manners, and counseling, statistically significant association between self-reported manners quality and four domains of HRQoL, and statistically significant association between TASO membership and domains of HRQoL. Plots from regression anatomies reported that self-reported treatment qualities had statistically significant associations with six domains of HRQoL. CONCLUSIONS Treatment burden, self-reported treatment qualities, ART obtainment, and TASO were possible determinants of individual domains of HRQoL among PLWH in Uganda. PLWH's HRQoL might be improved by promoting medical quality and optimizing ART obtainment in the healthcare providers' practice. Findings in this study had important implications for the redesign of clinical guidelines, healthcare delivery, and health care co-ordination among PLWH globally.

Measure of adherence to direct-acting antivirals as a predictor of the effectiveness of hepatitis C treatment. Int J Clin Pharm 2019; 41:1545-1554. [PMID: 31650508 DOI: 10.1007/s11096-019-00917-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Accepted: 09/25/2019] [Indexed: 12/23/2022]
Abstract
Background Adherence to direct-acting antivirals could be a predictor response to these treatments in hepatitis C. Objective To assess the ability of three methods of measuring adherence to direct-acting antivirals [pill counts, pharmacy dispensing record and Simplified Medication Adherence Questionnaire (SMAQ)] as predictors of their effectiveness. Setting Study conducted by the pharmacy department of the hospital. Methods: A retrospective study was performed. Patients ≥ 18 years with hepatitis C that started and completed treatment with direct-acting antivirals between the 1st-April-2015 and 28st-February-2016 were enrolled. To evaluate the predictive ability to obtain a response to treatment, Chi squared test, Mann-Whitney-U test and ROC-curves were used. Main outcome measure Adherence to antivirals was assessed by three methods and response to treatment, which was defined as obtaining a viral load of hepatitis C virus ≤ 15UI/ml at week 12 after the end of treatment. Results 128 patients were enrolled. The overall average adherence obtained with SMAQ (99.09%) was similar to the pill counts (96.40%, p = 0.043) and pharmacy dispensing record (91.10%, p = 0.02). There was no correlation between the percentage of patients considered as adherent by SMAQ (99.09%) and the achievement of response to treatment (96.40%, p = 0.999). The ROC-curve obtained for the pill count method shows a global area under the curve of 0.53. For pharmacy dispensing record method, patients with an adherence ≤ 66.66% have a high probability of not achieving response (sensitivity and specificity of 79.00% and 100.00%, respectively). Conclusions Pharmacy dispensing record is shown as the best indicator of adherence to predict therapeutic failure in our study.

Abstract
WHAT IS KNOWN AND OBJECTIVE Antiretroviral treatment (ART) is hampered by complicated regimens, high pill burden, drug-drug interactions, and frequent short- and long-term adverse effects, leading to decreased adherence. Over recent years, considerable effort has been directed at developing regimens that are less burdening. We undertook a 7-year retrospective study of the records of 264 HIV-infected subjects enrolled in a pharmaceutical care programme to document the progress made and to study the influence of the number of ART pills and doses on the level of treatment adherence. METHODS Antiretroviral dispensing records were analysed for the number of pills and doses administered and the ART adherence rate estimated. RESULTS AND DISCUSSION In 2005, the patients took a mean of 6·2 pills daily (CI 95%: 5·9-6·6), and 92·9% of them were on a twice-a-day (BID) dosage regimen. By 2012, the mean number of pills was reduced to 4·1 (CI 95%: 3·8-4·4), and only 50·9% were on a BID regimen. No statistically significant relation was observed between number of daily pills and doses and ART adherence reached by the patients in any of the analyses performed. WHAT IS NEW AND CONCLUSIONS There has been a continuous reduction in the number of pills and doses of antiretrovirals taken by individual patients over the last 7 years due largely to the introduction of improved treatments and regimens. More daily pills or doses was not associated with worse ART adherence in our pharmaceutical care programme.

Abstract
Introduction Specific environmental factors may play a role in the development of Pneumocystis pneumonia (PCP) in HIV-positive patients. The aim of this study was to estimate the PCP incidence and mortality in hospitalized HIV-positive patients in Spain during the combination antiretroviral therapy (cART) era (1997 to 2011), as well as to analyze the climatological factors and air pollution levels in relation to hospital admissions and deaths. Methods We carried out a retrospective study. Data were collected from the National Hospital Discharge Database and the State Meteorological Agency of Spain. A case-crossover analysis was applied to identify environmental risk factors related to hospitalizations and deaths. For each patient, climatic factors and pollution levels were assigned based on readings from the nearest meteorological station to his or her postal code. Results There were 13,139 new PCP diagnoses and 1754 deaths in hospitalized HIV-positive patients from 1997 to 2011. The PCP incidence (events per 1000 person-years) dropped from 11.6 in 1997 to 2000, to 5.4 in 2004 to 2011 (p<0.001). The mortality (events per 10,000 person-years) also decreased from 14.3 in 1997 to 2000, to 7.5 in 2004 to 2011 (p<0.001). Most hospital admissions and deaths occurred in the winter season and the fewest occurred in the summer, overlapping respectively with the lowest and highest temperatures of the year in Spain. Moreover, lower temperatures prior to PCP admission, as well as higher concentrations of NO2 and particulate matter up to 10 m in size (PM10) at the time of admission were associated with higher likelihoods of hospital admission due to PCP when two weeks, one month, 1.5 months or two months were used as controls (p<0.01). Furthermore, higher concentrations of ozone at one month (p=0.007), 1.5 months (p<0.001) and two months (p=0.006) prior to admission were associated with higher likelihoods of hospital admission with PCP. For PCP-related deaths, lower temperatures prior to admission and higher concentrations of atmospheric PM10 at the time of admission were related to higher likelihood of death when two weeks, one month and 1.5 months were used as controls (p<0.05). Conclusions PCP was a significant health problem in the cART era (1997 to 2011), and PCP epidemiology was adversely influenced by colder climatological factors and higher ambient air pollution levels.

Abstract
We evaluated the evolution over time of once-daily antiretroviral therapy in HIV-infected children and its relationship with adherence. An increase on the prevalence of once-daily antiretroviral therapy was observed over time (from 0.9% in 2002 to 44.2% in 2011). There was no difference in adherence regarding once-daily or BID regimens in 2011. Adherence was related to age and pill burden.

Abstract
BACKGROUND Opioid substitution therapy has improved the survival of heroin users with and without HIV infection. We aimed to analyze sex differences in mortality rates and predictors of death among those admitted to a methadone treatment program (MTP). METHODS Longitudinal study of patients enrolled in a MTP from 1992 to 2010. Socio-demographic and drug use characteristics, and markers of viral infections were assessed at entry. Vital status was ascertained by clinical charts and the mortality register. Four calendar periods were defined according to the introduction of preventive and treatment interventions in Spain. Predictors of death were analyzed by Cox regression models. RESULTS 1,678 patients (82.8% men) were included; age at first heroin use was 18.6 years (IQR: 16-23 years), and age at first entry into a MTP was 30.7 years (IQR: 26-36 years). A total of 441 (26.3%) deaths occurred during 15,124 person-years (p-y) of follow-up (median: 9.2 years, IQR: 4-13 years). HIV infection was the main predictor of death in men (HR = 3.5, 95% CI: 2.1-5.7) and women (HR = 3.2, 95% CI: 1.2-8.7 ) and main cause of death was HIV/AIDS. Overall mortality rate was 2.9 per 100 p-y (95% CI: 2.7-3.2 per 100 p-y) and death rates decreased over time: 7.4 per 100 p-y (95% CI: 6.3-8.8 per 100 p-y) for the 1992-1996 period to 1.9 per 100 p-y (95% CI: 1.6-2.4 per 100 p-y) for the 2007-2010 period. In women, a slightly increase in mortality was observed in recent periods specifically among HIV-positive women (3.7 per 100 p-y in period 2002-2006 and 4.5 per 100 p-y in 2007-2010). CONCLUSIONS Significant reductions in mortality of patients in MTP are observed after nineteen years of observation. However, HIV infection shows a great impact on survival, particularly among HIV-infected women.

Abstract
OBJECTIVE The AntiRetroviral Therapy with TMC114 ExaMined In naive Subjects (ARTEMIS) clinical trial examined the efficacy and safety of two ritonavir-boosted protease inhibitors (PI/r), darunavir/r 800/100 mg once daily (QD) and lopinavir/r 800/200 mg daily, both used in combination with tenofovir disoproxil fumarate/emtricitabine. This study aimed to assess the cost effectiveness of the darunavir/r regimen compared with the lopinavir/r regimen in treatment-naive adults with HIV-1 infection in Canada. METHODS A Markov model with a 3-month cycle time and six CD4 cell-count-based health states (>500, 351-500, 201-500, 101-200, 51-100, and 0-50 cells/mm(3)) followed a cohort of treatment-naive adults with HIV-1 infection through initial darunavir/r or lopinavir/r combination therapy and a common set of subsequent regimens over the course of their remaining lifetimes. Population characteristics and transition probabilities were estimated from the ARTEMIS clinical trial and other trials. Costs (in 2014 Canadian dollars), utilities, and mortality were estimated from Canadian sources and published literature. Costs and health outcomes were discounted at 5% per year. One-way and probabilistic sensitivity analyses were performed, including a simple indirect comparison of the darunavir/r initial regimen with an atazanavir/r-based regimen. RESULTS In the base-case lifetime analysis, individuals receiving initial therapy with the darunavir/r regimen experienced 0.25 more quality-adjusted life-years (QALYs) with lower antiretroviral drug costs (-$14,246) and total costs (-$18,402) than individuals receiving the lopinavir/r regimen, indicating that darunavir/r dominated lopinavir/r. In an indirect comparison with an atazanavir/r-based regimen, the darunavir/r regimen remained the dominant choice, but with lower cost savings (-$2,303) and QALY gains (0.02). Results were robust to a wide range of other changes in input parameter values, population characteristics, and modeling assumptions. The probabilistic sensitivity analysis demonstrated that the darunavir/r regimen was cost effective compared with the lopinavir/r regimen in over 86% of simulations for willingness-to-pay thresholds between $0 and $100,000 per QALY gained. CONCLUSIONS Darunavir/r 800/100 mg QD may be a cost-effective PI/r component of initial antiretroviral therapy for treatment-naive adults with HIV-1 infection in Canada.

Abstract
BACKGROUND Candidiasis is the most common opportunistic infection seen in human immunodeficiency virus (HIV)-infected individuals. The aim of our study was to estimate the candidiasis rate and evaluate its trend in HIV-infected children in Spain during the era of highly active antiretroviral therapy (HAART) compared to HIV-uninfected children. METHODS We carried out a retrospective study. Data were obtained from the records of the Minimum Basic Data Set from hospitals in Spain. All HIV-infected children were under 17 years of age, and a group of HIV-uninfected children with hospital admissions matching the study group by gender and age were randomly selected. The follow-up period (1997-2008) was divided into three calendar periods: a) From 1997 to 1999 for early-period HAART; b) from 2000 to 2002 for mid-period HAART; and c) from 2003 to 2008 for late-period HAART. RESULTS Among children with hospital admissions, HIV-infected children had much higher values than HIV-uninfected children during each of the three calendar periods for overall candidiasis rates (150.0 versus 6.1 events per 1,000 child hospital admissions/year (p < 0.001), 90.3 versus 3.1 (p < 0.001), and 79.3 versus 10.7 (p < 0.001), respectively) and for non-invasive Candida mycosis (ICM) rates (118.5 versus 3.8 (p < 0.001), 85.3 versus 2.3 (p < 0.001), and 80.6 versus 6.0 (p < 0.001), respectively). In addition, HIV-infected children also had higher values of ICM rates than HIV-uninfected children, except during the last calendar period when no significant difference was found (32.4 versus 1.2 (p < 0.001), 11.6 versus 0.4 (p < 0.001), and 4.6 versus 2.3 (p = 0.387), respectively). For all children living with HIV/AIDS, the overall candidiasis rate (events per 1,000 HIV-infected children/year) decreased from 1997-1999 to 2000-2002 (18.8 to 10.6; p < 0.001) and from 2000-2002 to 2003-2008 (10.6 to 5.7; p = 0.060). Within each category of candidiasis, both non-ICM and ICM rates experienced significant decreases from 1997-1999 to 2003-2008 (15.9 to 5.7 (p < 0.001) and 4.1 to 0.3 (p < 0.001), respectively). CONCLUSIONS Although the candidiasis rate still remains higher than in the general population (from 1997 to 2008), candidiasis diagnoses have decreased among HIV-infected children throughout the HAART era, and it has ceased to be a major health problem among children with HIV infection.

Abstract
INTRODUCTION GESIDA (AIDS Study Group) has proposed preferred regimens of antiretroviral treatment as initial therapy in HIV infected patients. The objective of this analysis is to compare the costs and effectiveness of darunavir/r QD and other ritonavir-boosted (/r) protease inhibitors (PIs) currently recommended in GESIDA guidelines for treatment-naïve patients. METHODS A cost-efficacy model compared the boosted PIs recommended as preferred or alternative treatment choices, each used with a nucleoside reverse transcriptase inhibitor backbone. Efficacy was measured by 48-week virological response (viral load < 50 copies/mL) adjusted by baseline viral load and CD4 cell count. To generate efficiency frontiers and cost-efficacy ratios, one-year antiretroviral therapy costs in Spain, and 48-week efficacy values were used. RESULTS The model estimated that starting treatment with darunavir/r QD was the most cost-effective choice compared with the other preferred PI/r based therapies. The average cost per patient with a virological response was lower for darunavir/r QD (13,420€) than for atazanavir/r QD (14,000€), or lopinavir/r BID (13,815€). Among the preferred PI/r-based therapies, darunavir/r QD also was estimated to be the most efficient option for treatment-naïve patients. Atazanavir/r QD and lopinavir/r BID were found to be «dominated» by darunavir/r) and, consequently, were outside the efficiency frontier of PI/r-based first-line treatment. Given a fixed budget of 10 million euros for PI/r-based first-line therapy, the model estimated that darunavir/r QD would yield more responders (745) than atazanavir/r QD (714), or lopinavir/r BID (724). At the same time, darunavir/r QD would reduce the number of individuals failing treatment (150) compared with atazanavir/r QD (172) and lopinavir/r BID (286). CONCLUSIONS In this model, darunavir/r QD was found to be the most cost-effective choice, among the preferred PI/r-based therapies recommended in the Spanish guidelines for treatment-naïve patients.

Abstract
BACKGROUND HIV-infected children are at increased risk of developing mycobacterial disease. The aim of this study was to estimate the change in mycobacterial disease rate in HIV-infected children and adolescents in the highly active antiretroviral therapy (HAART) era. METHODS We carried out a retrospective study. Data were obtained from the records of the minimum basic data set of hospitals in Spain from 1997 to 2008. The epidemiologic trends of mycobacterial diseases were evaluated through the following 3 calendar periods: early-period HAART (1997-1999), midperiod HAART (2000-2002), and late-period HAART (2003-2008). RESULTS We analyzed 1307 HIV-infected children and 5228 HIV-uninfected children. HIV-infected children had similar rate of tuberculosis (TB) and nontuberculous mycobacteria (NTM) disease, and they had an overall rate of mycobacterial disease higher than that of HIV-uninfected children (P < 0.001). In HIV-infected children, the highest rates were for pulmonary TB (15/42 [35.7%]) in the TB category and disseminated mycobacterium (9/42 [21.4%]) in the NTM category. The overall rate of mycobacterial disease (events per 1000 HIV-infected children-year) decreased from 1997-1999 to 2003-2008 (5.88-1.63, P = 0.007) and from 2000-2002 to 2003-2008 (4.20-1.63, P = 0.021). Furthermore, the rate of TB decreased from 1997-1999 to 2000-2002 (3.53-0.84, P = 0.016) and from 1997-1999 to 2003-2008 (3.53-1.31, P = 0.030), and the rate of NTM disease decreased from 2000-2002 to 2003-2008 (3.36-0.32, P = 0.002). CONCLUSIONS The rate of mycobacterial disease decreased among HIV-infected children in the HAART era, but the incidence of mycobacterial disease still remains higher than in the general population.

Abstract
This meta-analysis synthesizes eighty-four observational studies, conducted across twenty countries, to determine the mean proportion of people who reported ≥90% adherence to prescribed highly active antiretroviral therapy (HAART) and to identify the factors associated with high levels of adherence. Eight electronic databases were searched to locate all relevant studies available by January 2010, which were then coded for sample characteristics and adherence levels. The average rate of reporting ≥90% adherent HAART adherence is 62%. However, this proportion varies greatly across studies. In particular, a greater proportion of individuals maintaining ≥90% adherence to HAART is more likely in studies with higher proportions of men who have sex with men (MSM) and lower proportions of injection drug users (IDU), with participants in an earlier stage of infection, and in studies conducted in countries characterized by lower Human Development Index (HDI) scores.

Abstract
OBJECTIVES To estimate the percentage of adherence to highly-active antiretroviral therapy (HAART) in Spanish observational studies and to identify the variables associated with adherence. METHODS Seven electronic databases were used to locate the studies. Six inclusion criteria were established. Two coders codified the variables independently. Intercoder reliability was calculated. Publication bias was analyzed through the Begg, Egger and Trim and Fill tests. Homogeneity was evaluated using the Q test and the l² index. A random effects model was assumed to estimate both the overall percentage of adherence and to explain heterogeneity. RESULTS This meta-analysis included 23 observational studies, yielding a total of 34 adherence estimates. The sample was composed of 9,931 HIV-positive individuals (72% men) older than 18 years under treatment with HAART. The percentage of patients adhering to an intake of >90% of the prescribed antiretroviral drugs was 55%. Wide heterogeneity was detected (I² =91.20; 95%CI: 88.75-93.13). Adherence was mainly measured using a single strategy (47.8%), the most widely used being self-report (48.7%). In the univariate analysis, the following factors were significant: infection stages A (β=0.68, p <0.001) and B (β=-0.56, p <0.01), viral loads >200 copies/ml (β=-0.41, p <0.05) and <200 (β=0.39, p <0.05), and university education (β=-0.66, p<0.05). CONCLUSIONS The overall percentage of adherence was 55%, although this value may be an overestimate. Adherence was associated with infection stage A and with a viral load of <200 copies/ml.

Abstract
BACKGROUND Allergen-specific immunotherapy (SIT) is a treatment capable of modifying the natural course of allergy, so ensuring good adherence to SIT is fundamental. Up until now there has not existed an instrument specifically developed to measure patient satisfaction with SIT, although its assessment could help us to comprehend better and improve treatment adherence and effectiveness. The aim of this study was to develop an instrument to measure adult patient satisfaction with SIT. METHODS Items were generated from a literature review, focus groups with allergic adult patients undergoing SIT, and a meeting with experts. Potential items were administered to allergic patients undergoing SIT in an observational, cross-sectional, multicenter study. Item reduction was based on quantitative and qualitative criteria. A preliminary assessment of feasibility, reliability, and validity of the retained items was performed. RESULTS An initial pool of 70 items was administered to 257 patients undergoing SIT. Fifty-four items were eliminated resulting in a provisional instrument with 16 items. Factor analysis yielded four factors that were identified as perceived efficacy, activities and environment, cost-benefit balance, and overall satisfaction, explaining 74.8% of variance. Ceiling and floor effects were negligible for overall score. Overall score was associated with the type and intensity of symptoms. CONCLUSION This is the first attempt to develop a satisfaction with SIT measure from the perspective of the allergic patient, and evidence has been found in favor of its reliability and validity.

Abstract
PURPOSE A comprehensive study comparing the costs and efficacies of darunavir/ritonavir 800/100 mg qd and the other ritonavir-boosted (/r) protease inhibitors (PIs) recommended for treatment-naïve individuals with HIV-1 infection would help health care decision makers identify the value of each boosted PI. METHODS A cost-efficacy model was developed to compare the five recommended boosted PIs, each used with a tenofovir-based nucleotide/nucleoside reverse transcriptase inhibitor backbone. Efficacy was measured by virologic response (ie, HIV-1 ribonucleic acid < 50 copies/mL) at 48 weeks, based on a systematic review and meta-analysis of recent clinical trials. One-year antiretroviral therapy costs and 48-week efficacy values were used to generate the efficiency frontier and cost-efficacy ratios. RESULTS Darunavir/r was the most efficacious boosted PI, with an incremental cost-efficacy ratio of $27,390 per additional individual with virologic response, compared with fosamprenavir/r. All other regimens were dominated. Darunavir/r combination therapy also had one of the lowest average costs ($26,287) per individual with virologic response, resulting in a maximal number of individuals successfully treated within a fixed budget. The model results were robust in variability and sensitivity analyses. CONCLUSION Darunavir/r 800/100 mg qd combination therapy represents a cost-efficacious option for treatment-naïve individuals with HIV-1 infection in the United States.

Abstract
Etravirine (ETR) is a new antiretroviral drug of the non-nucleoside reverse transcriptase inhibitor (NNRTI) family that has recently been approved by the regulatory agencies for the treatment of patients with prior experience with antiretrovirals, evidence of active viral replication, and who harbor multidrug resistant HIV-1 strains. In this context, in Europe, the use of this drug has been authorized combined with boosted protease inhibitors and nucleoside reverse transcriptase inhibitors. This approval was based on the results of the randomized double-blind DUET studies, in which the ETR arm was statistically superior to the placebo arms in terms of virological efficacy, immunological recovery, clinical progression and health- related quality of life. These studies showed that ETR was as well-tolerated as placebo, except for the appearance of rash, which was more common in the ETR arm. However, rash was usually mild or moderate and caused discontinuation of ETR in only 2% of the patients. The characteristics of ETR, i.e., potency, benign safety profile, resistance profile, pharmacokinetic characteristics, and drug interactions suggest that the use of this drug may go beyond its currently approved indications. Nevertheless, the evidence supporting these alternative uses is still scarce, although a randomized, double-blind, placebo controlled trial (SENSE) is under way in treatment-naïve patients. In this trial ETR will be administered once daily and the principal objective is to show that ETR has better tolerability in the central nervous system (CNS) than efavirenz. Moreover, the tolerability profile in the CNS, liver, and even skin suggest that ETR may be a good option when there are toxicity problems, or a risk of toxicity, with first-generation NNRTIs. When there is virological failure with an initial first-generation NNRTI-based regimen, the differential resistance profile of ETR may allow this drug to be used to construct a rescue combination. ETR is not teratogenic and can therefore be safely used in pregnant or fertile women. Finally, ETR has an excellent drug-drug interaction profile, which may be useful in patients administered other medications. This interaction profile may be especially important in areas with a high prevalence of methadone treatment, as both drugs can be coadministered safely. ETR has received approval as advanced rescue therapy. However, the characteristics of this drug suggest that it may be useful in a series of potential indications, due to its antiviral potency, differential resistance profile, safety, tolerability and drug-drug interaction profile.

Abstract
BACKGROUND Treatment of hepatitis C virus (HCV) infection with pegylated interferon/ribavirin achieves sustained virological response in up to 56% of HCV mono-infected patients and 40% of HCV/human immunodeficiency virus (HIV)-co-infected patients. The relationship of patient adherence to outcome warrants study. AIM To review comprehensively research on patient-missed doses to HCV treatment and discuss applicable research from adherence to HIV antiretroviral therapy. METHODS Publications were identified by PubMed searches using the keywords: adherence, compliance, hepatitis C virus, interferon and ribavirin. RESULTS The term 'non-adherence' differs in how it is used in the HCV from the HIV literature. In HCV, 'non-adherence' refers primarily to dose reductions by the clinician and early treatment discontinuation. In contrast, in HIV, 'non-adherence' refers primarily to patient-missed doses. Few data have been published on the rates of missed dose adherence to pegylated interferon/ribavirin and its relationship to virological response. CONCLUSIONS As HCV treatment becomes more complex with new classes of agents, adherence will be increasingly important to treatment success as resistance mutations may develop with suboptimal dosing of HCV enzyme inhibitors. HIV adherence research can be applied to that on HCV to establish accurate methods to assess adherence, investigate determinants of non-adherence and develop strategies to optimize adherence.
