Direct monthly highly active antiretroviral therapy supply - a method to increase patient's adherence and outcome. Experience of one AIDS centre in Israel.

In Israel, antiretroviral therapy (ART) is available (at local pharmacies) without cost. Nevertheless, poor adherence, especially of immigrants from Africa, leads to a high rate of treatment failures. Our study looked whether direct monthly ART supply in our AIDS centre has an effect on adherence and outcome. A total of 385 HIV (clade C) immigrants from Africa that were treated with ART for >2 years prior to the initiation of the study were evaluated. During the first 2 years, ART medications were supplied by local pharmacies. Thereafter (next 2 years), all patients received medications, monthly at our centre. Adherence, immunological (CD4) and virological (VL) outcome at the end of the two study periods were determined. At baseline, only 75% of the patients attended more than 90% of scheduled visits with 57% treatment adherence. Virological failure (VL >40 copies/ml) was observed in 53% of the patients. As a result of our intervention (2 years of direct monthly ART supply), visits and treatment adherence significantly increased (90% and 84%, respectively;p < 0.001). Concomitantly, virological failure rate significantly dropped to 28% (p < 0.001). Direct monthly supply of ART is a relatively low-cost mode to improve patient's adherence and immunological/virological outcomes.

[Demographic and clinical characterizations of newly diagnosed patients with HIV/AIDS above fifty years of age].

BACKGROUND: Major changes happened in the last decade in the HIV/AIDS pandemic. The disease is no longer limited to young age. Due to the effectiveness of HAART (Highly Active Anti-Retroviral Therapy) as well as new diagnosis in older age groups, many patients in AIDS centers are above 50 years of age. AIM: To determine the prevalence, demographics and clinical characteristics of newly diagnosed HIV/AIDS patients older than 50 years compared to younger newly diagnosed patients. METHODS: Retrospective single center analysis of the demographics and clinical characterizations of 62 newly diagnosed HIV/AIDS patients over 50 years of age. RESULTS: The average age at diagnosis of the whole cohort was 39+/-16 years. There was a gradual increase in the age at diagnosis over the years, as well as the percent of patients above the age of 50 diagnosed with the disease. In comparison to younger patients, in the older group there were more males compared to females and less patients who acquired the HIV/AIDS in unprotected homosexual sex. Furthermore, CD4 cells counts were lower and viral load leveLs were higher at diagnosis in the older group. Despite good adherence, patients above the age of 50 don't achieve adequate immunological response and many are left with significant immunodeficiency (CD4<200). CONCLUSION: The prevaLence of patients above the age of 50 Living with HIV/AIDS in Israel is rising. Programs aimed at prevention, education and screening for this unique group are mandatory. An AIDS center should adopt new programs and routines to cope with the increasing number of patients over the age of 50 Living with HIV/AIDS.

[HIV post exposure prophylaxis therapy - the experience of two major AIDS centers].

BACKGROUND: During recent years, the use of antiretroviral therapy expanded beyond the treatment of HIV-infected patients. Since the outset of the HIV epidemic, antiretroviral drugs were also used for post-exposure prevention of HIV infection in health workers and implemented after possible exposure during sex. In this study, we summarize the cases from the AIDS center in the Kaplan Medical Center and the Sheba Medical Center after possible exposure to HIV (occupational or sexual). AIM: The study aims to validate the different types of potential exposures to HIV encountered, the treatment and outcomes. METHODS: All the data regarding attendance at the AIDS Center in the Kaplan Medical Center during the years 2008-2010 for any possible HIV exposure (occupational or sexual) and for sexual exposure in the Sheba Medical Center AIDS Clinic during the years 2003-2008 was collected retrospectively. RESULTS: During the years of the study, 448 patients attended the Kaplan Medical Center for consultation after a potential exposure to HIV; 314 of the cases were because of occupational exposure, however, only in 11 (3.5%) of the cases, post exposure prophylaxis (PEP) treatment was advised. In the other 134 patients who attended for non-occupational potential exposure to HIV (18 cases of needle stick or sharp object injury and 116 of sexual exposure), for 46 (40%) of these cases, PEP was recommended. No evidence of HIV infection was found for any of the 448 patients who attended the clinic for possible exposure to HIV, regardless of the consultation that they received. In the Sheba Medical Center, during the years 2003-2008, 175 patients attended for consuLtation after potential sexual exposure to HIV. The medical staff of the clinic decided, after risk assessment, to recommend PEP to 140 (80%) of the cases. Similarly, in this case, no evidence of HIV infection was found (regardless of whether PEP was given or not). DISCUSSION: In potential occupational exposure to HIV it is possible, in most cases, to assess the risk for infection sufficiently so that only a few cases will need PEP. In potential sexual exposure to HIV, there are many cases where data regarding the potential source of infection is partial or missing, making the risk assessment more difficult. This may be the reason for the high percentage of patients in this situation who received PEP. From the data in this study, our cohort support PEP as being effective and safe.
