RESUMO

The effect of early adherence on long-term viral suppression was assessed among 1281 patients with HIV starting a protease inhibitor-containing regimen in 1997-1999, followed up to 12 years. Association between 4-month adherence (3-level score) and prolonged viral suppression was evaluated using a multivariate mixed logistic model in 891 eligible patients. High 4-months adherence [odds ratio (95% confidence interval): 3.72 (1.98 to 6.98)] was associated with long-term prolonged viral suppression, irrespective of maintenance adherence. This unexpected long-term virological impact of early adherence reinforces the message that, when starting antiretrovirals, all means should be mobilized to ensure optimum early adherence to achieve prolonged antiretroviral success.

RESUMO

BACKGROUND & AIMS: The systematic use of rapid tests performed at points-of-care may facilitate hepatitis B virus (HBV) screening and substantially increase HBV infection awareness. The aim of this study was to evaluate the effectiveness of such tests for HBsAg and anti-HBsAb detection among individuals visiting a variety of healthcare centers located in a low HBV-prevalent area. METHODS: Three rapid tests for hepatitis B surface antigen (HBsAg) detection (VIKIA, Determine and Quick Profile) and one test for anti-hepatitis B surface antibody (anti-HBsAb) detection (Quick Profile) were evaluated in comparison to ELISA serology. Sensitivity (Se), specificity (Sp), positive and negative predictive values (PPV and NPV, respectively) and area under the ROC curve were used to estimate test performance. Non-inferiority criteria of the joint Se, Sp were set at 0.80, 0.95. RESULTS: Among the 3956 subjects screened, 85 (2.1%) were HBsAg-positive and 2225 (56.5%) had a protective anti-HBsAb titer. Test Se and Sp (lower bound of 97.5% CI) were as follows: 96.5% (89.0%), 99.9% (99.8%) for Vikia; 93.6% (80.7%), 100.0% (99.8%) for Determine; and 90.5% (80.8%), 99.7% (99.5%) for Quick Profile; with all three tests achieving minimal non-inferiority criteria. False negatives were typically observed in inactive HBsAg carriers. The anti-HBsAb Quick Profile test had excellent specificity (97.8%) and PPV (97.8%) albeit low sensitivity (58.3%), thus failing to establish non-inferiority. CONCLUSIONS: All three HBsAg rapid tests could be considered ideal for HBV screening in low HBV-prevalent countries, given the ease of use, rapidity, and high classification probabilities. The anti-HBsAb Quick Profile could be considered reliable only for positive tests.

RESUMO

Dermatological adverse events (AEs) are an existing concern during hepatitis C virus (HCV) infection and peginterferon/ribavirin treatment. HCV infection leads to dermatological and muco-cutaneous manifestations including small-vessel vasculitis as part of the mixed cryoglobulinemic syndrome. Peginterferon/ribavirin treatment is associated with well-characterized dermatological AEs tending towards a uniform entity of dermatitis. New direct-acting antivirals have led to significant improvements in sustained virologic response rates, but several have led to an increase in dermatological AEs versus peginterferon/ribavirin alone. In telaprevir trials, approximately half of treated patients had rash. More than 90% of these events were Grade 1 or 2 (mild/moderate) and in the majority (92%) of cases, progression to a more severe grade did not occur. In a small number of cases (6%), rash led to telaprevir discontinuation, whereupon symptoms commonly resolved. Dermatological AEs with telaprevir-based triple therapy were generally similar to those observed with peginterferon/ribavirin (xerosis, pruritus, and eczema). A few cases were classified as severe cutaneous adverse reaction (SCAR), also referred to as serious skin reactions, a group of rare conditions that are potentially life-threatening. It is therefore important to distinguish between telaprevir-related dermatitis and SCAR. The telaprevir prescribing information does not require telaprevir discontinuation for Grade 1 or 2 (mild/moderate) rash, which can be treated using emollients/moisturizers and topical corticosteroids. For Grade 3 rash, the prescribing information mandates immediate telaprevir discontinuation, with ribavirin interruption (with or without peginterferon) within 7 days of stopping telaprevir if there is no improvement, or sooner if it worsens. In case of suspicion or confirmed diagnosis of SCAR, all study medication must be discontinued.

RESUMO

OBJECTIVES: To understand the virological mechanisms of 2-year persistence of multidrug-resistant virus without selective antiretroviral pressure in HIV-1-infected patients. PATIENTS AND METHODS: Two patients were contaminated recently by their HIV-1-infected partners, who had received, before the transmission, all available antiretroviral drugs and who exhibited a severe therapeutic failure. The resistance mutations analysis was performed by clonal sequencing of 1.2 kb of pol gene in plasma of index and sources patients. Sequencing of HIV-1 DNA was performed in PBMCs of index patients. RESULTS: Genotypic testing performed in index patients at time of seroconversion showed resistance mutations to three classes of drugs. All mutations were linked on the same viral genome and all quasispecies carried all mutations. No wild-type virus was detected. The same results were found in source patients and showed that all mutations were transmitted. In the index patients, all mutations persisted over 2 years without antiretroviral treatment. Moreover, the resistance mutations were all archived in the cellular reservoir. Viral load and CD4 count of index patients remained unchanged during 2 years of follow-up. DISCUSSION: Only multidrug-resistant viruses were detected in the source patients and could be transmitted in index patients. In the latter, an expansion of predominant multidrug-resistant quasispecies and the 'archival' of all mutations were observed. These results explain the persistence of mutations and suggest that it is highly difficult to return to a wild-type viral population, sensitive to an antiretroviral treatment. The treatment of index patients is limited and the major risk is the transmission of these multidrug-resistant viruses. This work was presented in part in the XII International HIV Drug Resistance Workshop, Los Cabos, Mexico, June 2003; and in the 2nd IAS Conference on HIV Pathogenesis & Treatment, Paris, France, July 2003.

RESUMO

Esta pesquisa longitudinal estudou a organização psíquica dos indivíduos, gestionários de um tratamento complexo, confrontados às dificuldades da vida cotidiana, durante o primeiro ano de tratamento pela terapia antiretroviral altamente ativa (HAART). O objetivo da pesquisa era o de discriminar os fatores que favorecem e os que perturbam este processo. Constata-se a importância determinante das relações de apoio para confortar a estima de si que dá sentido ao esforço de prosseguir o tratamento.

RESUMO

Herpes is a viral infection which increases, specifically genital herpes. The aim of this survey was to assess the perception of herpes in the general population and in patients with herpes in France using a self-administered questionnaire. A total of 10,000 persons answered the questionnaire among which 128 patients presented herpes. This study showed that only 5% of the French population knew that herpes was a viral infection, and 7% a sexually transmitted disease. Among patients with genital herpes only 34% indicated a sexual relationship and a mode of contamination. The interference with sexual and social life is important. Development of information and communication on herpes appears crucial.

RESUMO

Co-infection by HIV and HSV viruses his known since AIDS epidemic has started. A better knowledge of the strong relations between the two viruses has demonstrated that HSV infection increases the rate of HIV transmission. HSV2 infection is occurring in younger people below 20 years old where incidence has much increased those last years, in teen agers with a high number of sexual partners. The increase in HIV infection and transmission in HSV positive patients leads to treat genital ulcers to decline the rate of HIV and HSV transmission.
