Abstract
BACKGROUND Both under- and over-nutrition may occur among human immunodeficiency virus (HIV)-infected individuals and impact on the course of the acquired immune deficiency syndrome (AIDS) and its management due to the close interaction between immunity and nutrition. We investigated occurrence of undernutrition, excess weight and lipid abnormalities among antiretroviral naïve HIV-infected adults in Addis Ababa, Ethiopia. METHODS A cross-sectional study on 594 antiretroviral therapy (ART) naïve HIV-infected adults was conducted in four hospitals in Addis Ababa from February to September 2013. Hematological parameters (CD4+ T cell count and hemoglobin concentration), fasting serum glucose, total cholesterol (TC) and triglycerides (TG) were determined. Information on socio-demographic, anthropometric and World Health Organization (WHO) clinical stages was collected from patient clinical records, and triangulated by structured questionnaire. Height and weight measurements were taken and body mass index (BMI), undernutrition (BMI <18.5 kg/m2) and excess weight (BMI ≥25 kg/m2) determined. Statistical comparisons were made to identify significant factors associated with nutritional status and lipid profiles. RESULTS The prevalence of undernutrition was 15.1%, and the prevalence of excess weight was 22.1%, including 5.4% who were obese. The prevalence of hypercholesterolemia was 16.6% and it was higher in women (18.9%) than in men (11.0%) (p<0.05). However, the prevalence of hypertriglyceridemia was 29.8%. There was significant positive Spearman correlation between CD4+ T cell count and serum TC (r = 0.210, p<0.001), but no correlation was observed between CD4+ T cell count and TG (r = -0.007, p>0.05). Age categories 30-39 and 40-79, and WHO clinical stages III/IV for undernutrition; age categories 30-39 and 40-79, WHO clinical stages III/IV and TC ≥200 mg/dL for excess weight; and being female, age categories 30-39 and 40-79, and hypertriglyceridemia for hypercholesterolemia were found to be independent predictors by binomial logistic regression analysis. CONCLUSION Undernutrition, excess weight, hypercholesterolemia and hypertriglyceridemia were variably prevalent in ART naïve HIV-infected populations. This emphasizes the need for targeted nutritional programs as an integral part of HIV/AIDS care. Lipid levels need to be monitored regularly in patients whether on or off ART. In addition, improvement on household income and positive change in lifestyle and/or nutritional treatment to reduce morbidity and mortality are necessary interventions in HIV/AIDs patient management.

Incidence and predictors of single drug discontinuation according to the presence of HCV coinfection in HIV patients from the ICONA Foundation Cohort Study. Eur J Clin Microbiol Infect Dis 2018; 37:871-881. [PMID: 29318459 DOI: 10.1007/s10096-017-3180-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2017] [Accepted: 12/25/2017] [Indexed: 10/18/2022]
Abstract
To evaluate incidence rates of and predictors for any antiretroviral (ART) drug discontinuation by HCV infection status in a large Italian cohort of HIV infected patients. All patients enrolled in ICONA who started combination antiretroviral therapy (cART) containing abacavir or tenofovir or emtricitabine or lamivudine plus efavirenz or rilpivirine or atazanavir/r or darunavir/r (DRV/r) or lopinavir/r or dolutegravir or elvitegravir or raltegravir were included. Multivariate Poisson regression models were used to determine factors independently associated with single ART drug discontinuation. Inverse probability weighting method to control for potential informative censoring was applied. Data from 10,637 patients were analyzed and 1,030 (9.7%) were HCV-Ab positive. Overall, there were 15,464 ART discontinuations due to any reason in 82,415.9 person-years of follow-up (PYFU) for an incidence rate (IR) of 18.8 (95% confidence interval [95%CI] 18.5-19.1) per 100 PYFU. No difference in IR of ART discontinuation due to any reason between HCV-infected and -uninfected patients was found. In a multivariable Poisson regression model, HCV-infected participants were at higher risk of darunavir/r discontinuation due to any reason (adjusted incidence rate ratio = 1.5, 95%CI 1.01-2.22, p value = 0.045) independently of demographics, HIV-related, ART and life-style factors. Among DRV/r treated patients, we found that HCV-viremic patients had twice the risk of ART discontinuation due to any reason than HCV-aviremic patients. In conclusion, HIV/HCV coinfected patients had a marginal risk increase of DRV/r discontinuation due to any reason compared with those without coinfection.

Abstract
BACKGROUND Although modern combination antiretroviral therapy (cART) regimens are better tolerated and less complex than earlier treatments, regimen modification or discontinuation remains a concern. METHODS We studied HIV Outpatient Study (HOPS) participants who initiated the first or second cART regimens during: 1996-1999, 2000-2003, 2004-2007, and 2008-2011. We analyzed regimen durability (time to regimen modification) and success (achieving undetectable plasma HIV RNA) for the first and second cART regimens using Kaplan-Meier curves and log-rank tests, and examined factors associated with durability and success of the first cART regimen using proportional hazards models. RESULTS Durability of cART was progressively longer for cART regimens initiated in more recent periods: median first cART regimen durations were 1.0, 1.1, 2.1, and 4.6 years in 1996-1999, 2000-2003, 2004-2007, and 2008-2011, and the median second cART durations were 0.9, 1.2, 2.8, and 3.9 years, respectively (both P < 0.001). Comparing 1996-1999 and 2008-2011, the percentage of patients who achieved an undetectable HIV RNA within 6 months of first cART initiation increased from 65% to 81% and from 63% to 80% on second cART (both P < 0.001). Among patients initiating first cART during 2008-2011, black non-Hispanic/Latino race/ethnicity and ≥ twice-daily dosing were significantly associated with higher rates of regimen modification (P < 0.05), and higher baseline HIV RNA levels were associated with failure to achieve an undetectable HIV RNA (P < 0.001). CONCLUSIONS Among HIV-infected U.S. adults in routine HIV care, durability of the first and second cART regimens and the likelihood of prompt virological suppression increased during 1996-2011, coincident with the availability of more tolerable, less complex cART options.

Abstract
OBJECTIVES Sustained optimal use of combination antiretroviral therapy (cART) has been shown to decrease morbidity, mortality and HIV transmission. However, incomplete adherence and treatment interruption (TI) remain challenges to the full realization of the promise of cART. We estimated trends and predictors of treatment interruption and resumption among individuals in the Canadian Observational Cohort (CANOC) collaboration. METHODS cART-naïve individuals ≥ 18 years of age who initiated cART between 2000 and 2011 were included in the study. We defined TIs as ≥ 90 consecutive days off cART. We used descriptive analyses to study TI trends over time and Cox regression to identify factors predicting time to first TI and time to treatment resumption after a first TI. RESULTS A total of 7633 participants were eligible for inclusion in the study, of whom 1860 (24.5%) experienced a TI. The prevalence of TI in the first calendar year of cART decreased by half over the study period. Our analyses highlighted a higher risk of TI among women [adjusted hazard ratio (aHR) 1.59; 95% confidence interval (CI) 1.33-1.92], younger individuals (aHR 1.27; 95% CI 1.15-1.37 per decade increase), earlier treatment initiators (CD4 count ≥ 350 vs. <200 cells/μL: aHR 1.46; 95% CI 1.17-1.81), Aboriginal participants (aHR 1.67; 95% CI 1.27-2.20), injecting drug users (aHR 1.43; 95% CI 1.09-1.89) and users of zidovudine vs. tenofovir in the initial cART regimen (aHR 2.47; 95% CI 1.92-3.20). Conversely, factors predicting treatment resumption were male sex, older age, and a CD4 cell count <200 cells/μL at cART initiation. CONCLUSIONS Despite significant improvements in cART since its advent, our results demonstrate that TIs remain relatively prevalent. Strategies to support continuous HIV treatment are needed to maximize the benefits of cART.

Abstract
OBJECTIVES The aim of this study was to describe the rates and predictors of discontinuing first-line antiretroviral therapy in the different eras of treatment over a nearly 20 year period initiated in British Columbia between 1992 and 2010. METHODS All naive adults who started antiretroviral therapy (first-line antiretroviral therapy) at any hospital or clinic in British Columbia (Canada) in 1992-2010 were included in this population-based retrospective cohort study. We were primarily interested in whether the era of treatment (1992-95, 1996-2000, 2001-05 and 2006-10) was associated with discontinuation (stopping or switching of initial treatment) within 3 years of starting therapy. Weibull survival analysis was used to model the era of treatment and its association with time to discontinuation. RESULTS The study included 7901 patients. Overall, the probability of discontinuing at 12, 24 and 36 months of treatment was 52%, 68% and 76%, respectively. In the adjusted model, variables associated with discontinuing were earlier treatment era, younger age, low adherence and lower baseline CD4 count. Regarding the 2006-10 period, the probability of discontinuing at 12, 24 and 36 months was 36%, 47% and 53%, respectively. In the adjusted model, the variables associated with discontinuation were younger age, female gender, AIDS-defining illnesses at baseline, low adherence and a protease inhibitor (PI)-based regimen. CONCLUSIONS Discontinuation rates of first-line therapy have decreased over time, but are still quite high even for the latest drug combinations. In the most recent era, younger women on a PI regimen and those not achieving optimal adherence had the highest risk of discontinuing first-line antiretroviral therapy.
