Emerging evidence suggests financial incentives (FIs) improve medication adherence in select populations. A small proportion of adolescents with perinatal HIV (PaHIV) transfer to adult services with established poor adherence and advanced disease. We describe a single center adherence intervention combining FIs with motivational interviewing (MI). Eligible patients (PaHIV,16-25 years, CD4 count ≤ 200, off ART despite multiple attempts) received MI, and FI dependent on viral load (VL) reduction for 1 year. Outcome measures compared CD4 gain from baseline at 1 year and 12 months post cessation of FI/MI. Eleven young people enrolled; median age 19 years, 8 female. Baseline median CD4 count 30 cells/μL (IQR 10-160), VL 12,870 c/mL. Outcomes at 12 months: 9/11 ever achieved VL < 50, 5 sustained undetectable VL, median CD4 140, mean CD4 gain 90 cells/μL at 1 year. Twelve months post cessation of MI/FI; six VL < 50, median CD4 75, mean CD4 gain 122 cells/μL. Total FI expenditure £1,350: £68 per 50 CD4 cells at 1 year, £55 at 24 months. To prevent death, adolescents with PaHIV require novel interventions to reverse poor patterns of adherence established since childhood. FI/MI improved virological and immunological outcomes with minimal expenditure. Extension of this pilot work for vulnerable individuals is now indicated.
Objective: Adolescence is the only age group globally where HIV associated mortality is rising, with poorer outcomes at all stages of the care cascade compared to adults. We examined post-transition outcomes for young adults living with perinatal HIV (YAPaHIV).
Introduction
Since the advent of Highly Active Anti-Retroviral Therapy (HAART), men with HIV experience good quality of life and expect to have normal sexual function. However, it appears that men infected with HIV commonly complain of sexual problems. There is evidence that men on HAART develop low sexual desire that is associated with raised estradiol levels. It has been postulated that abnormal metabolism seen in this group of men increases the aromatization of testosterone to estradiol. We hypothesized that letrozole, an aromatase inhibitor that inhibits the conversion of testosterone to estradiol, would be beneficial in these men.
Aim
The aim of this study was to compare the effects of testosterone vs. an aromatase inhibitor, letrazole, in HIV-infected men with raised estradiol and low sexual desire.
Methods
Thirteen men who have sex with men on HAART with low sexual desire as well as raised estradiol levels (>120 pmol/L) were randomly allocated to receive either parenteral testosterone (Sustanon 250 intramuscular injection) (N = 6) or letrozole 2.5 mg orally daily (N = 7) for 6 weeks.
Main Outcome Measures
Sex steroid hormone assays, sex hormone-binding globulin, virological, hematological, and biochemical parameters were measured before and after treatment. Each subject was given the Spector Sexual Desire Inventory and the Depression/Anxiety Stress Scale before and immediately after treatment. Subjects were also asked to estimate the number of actual sexual acts before and after treatment.
Results
Inventory data showed a rise in dyadic desire in both treatment arms. Mean actual sexual acts rose from 0.33 to 1.5 in the testosterone group and from 0.43 to 1.29 for the letrozole group. Luteinizing hormone increased in seven of seven men on letrozole. Serum testosterone increased in seven of seven men on letrozole. There were no adverse events from either medication.
Conclusion
Letrozole may be useful in the management of men on HAART who have low sexual desire.
