Although Ethiopia has been scaling up the antiretroviral therapy (ART) services, low retention in care of patients remains one of the main obstacles to treatment success. We report data on retention in care and its associated determinants in Tigray, Ethiopia.We used data from the CASA project, a prospective observational and multi-site study of a cohort of HIV-infected patients who initiated ART for the first time in Tigray. Four participating health facilities (HFs) located in the South of Tigray were considered for this study. Patients were followed for one year after ART initiation. The main outcome measure was represented by the current retention in care, defined as the proportion of patients who were alive and receiving ART at the same HF one year after ART initiation. Patients who started ART between January 1, 2013 and December 31, 2013 were included in this analysis. Patients were followed for one year after ART initiation. The determinants of retention were analysed using univariate and multivariate Cox Proportional Hazards model with robust sandwich estimates to account for within HF correlation.The four participating HFs in Tigray were able to retain overall 85.1% of their patients after one year from starting ART. Loss to follow-up (5.5%) and transfers to other HF (6.6) were the main determinant of attrition. A multivariate analysis shows that the factors significantly associated with retention were the type of HF, gender and active TB. Alamata health center was the HF with the highest attrition rate (HR 2.99, 95% CI: 2.77-3.23). Active TB (HR 1.72, 95% CI: 1.23-2.41) and gender (HR 1.64, 95% CI: 1.10-2.56) were also significantly associated with attrition.Although Ethiopia has significantly improved access to the ART program, achieving and maintaining a satisfactory long-term retention rate is a future goal. This is difficult because of different retention rates among HFs. Moreover specific interventions should be directed to people of different sex to improve retention in care in male population.

AbstractEmergence of resistance is one of the drawbacks associated with treatment interruptions (TI), especially when regimens include nonnucleoside reverse transcriptase inhibitors (NNRTIs), because of their long half-life. ISS-PART was a randomized trial comparing a continuous treatment arm with a TI arm in which 136 patients underwent five treatment interruptions, each followed by 3 months of therapy, over 2 years. To minimize the potential risk of developing resistance, patients on NNRTIs were requested, at each TI, to interrupt nevirapine (NVP) or efavirenz (EFV) 3 or 6 days before the other drugs, respectively. To determine if a difference in drug levels existed during TIs between patients with and without resistance we compared NNRTI concentrations in the 12 patients (6 on NVP and 6 on EFV) who developed NNRTI mutations during TIs with those of 20 patients (10 on NVP and 10 on EFV) who retained a wild-type virus. Genotypic resistance and drug concentrations were analyzed on plasma samples collected 15 days after each drug interruption. Overall, EFV was quantifiable in 28% (16/57) and NVP in 22.9% (14/61) of evaluable samples collected during TIs, with no difference between patients with and without mutations. Median EFV or NVP concentrations at each TI were not significantly different between patients with and without mutations. Although the staggered stop strategy was not completely effective in preventing exposure to suboptimal levels, no evident correlation was found between NNRTI concentrations and the emergence of resistance, suggesting that other factors (such as the presence of drug-resistant minority variants) could also play an important role in these patients.

AbstractWe assessed the safety and efficacy of reconstructive therapy with facial fillers for the treatment of HIV-associated facial lipoatrophy (FLA) through a randomized, controlled, open-label single-center study. A total of 134 HIV-infected patients with severe FLA were randomly assigned to receive immediate (67 patients) or delayed (67 patients) facial injections of poly-l-lactic acid (PLA) or polyacrylamide gel (PAIG). Outcome measures included changes in physician and patient FLA severity scale, adverse events, and changes in health-related quality of life (HRQoL) and anxiety using validated measures. The mean average study follow-up was 27 weeks for the immediate and 25 weeks for the delayed subjects. Adverse events were mild and resolved after a mean of 4 days. Compared to patients randomized to the delayed treatment group, patients assigned to the immediate treatment group had significantly lower physician-rated (0.0 versus −3.0; p< 0.0001) and patient-rated (0.1 versus −1.8; p< 0.0001) FLA severity scores. By contrast, measures exploring HRQoL and anxiety did not show any significant difference between patients randomized to the immediate and deferred groups. Reconstructive therapy with facial fillers was effective and safe and led to significant improvements in FLA severity. However, no significant gains in HRQoL, relational and psychological consequences of body changes, and anxiety-related concerns were observed. Studies should be performed to identify patients who could maximally benefit from filling interventions for FLA. [ABSTRACT FROM AUTHOR]

The health-related quality of life (HRQoL) outcomes in HIV-infected, treatment-naive patients starting different HAART regimens in a 3-year, randomized, multinational trial were compared. HRQoL was measured in a subgroup of patients enrolled in the INITIO study (153911), using a modified version of the MOS-HIV questionnaire. The regimens compared in the INITIO trial were composed by two NRTIs (didanosine stavudine) plus either an NNRTI (efavirenz) or a PI (nelfinavir), or both (efavirenz nelfinavir). Primary HRQoL outcomes were Physical and Mental Health Summary scores (PHS and MHS, respectively). During follow-up, an increase of PHS score was observed in all treatment arms. The MHS score remained substantially unchanged with the four-drug combination and showed with both NNRTI- and PI-based three-drug regimens a marked trend toward improvement, which became statistically significant when a multiple imputation method was used to adjust for missing data. Overall, starting all the combination regimens compared in the INITIO study was associated with a maintained or slightly improved HRQOL status, consistently with the positive immunological and virological changes observed in the main study. The observed differences in the MHS indicate a possible HRQoL benefit associated to the use of three-drug, two-class regimens and no additional benefit for the use of four-drug, three-class regimens, confirming that three-drug, two-class regimens that include two NRTIs plus either an NNRTI or a PI should be preferred as initial treatment of HIV infection.
