ABSTRACT
Abstract INTRODUCTION: In 2013, combination therapy using peginterferon, ribavirin, and boceprevir or telaprevir was introduced to treat hepatitis C virus genotype 1 infection in Brazil. The effectiveness of this therapy in four Brazilian regions was evaluated. METHODS: Clinical and virological data were obtained from patients of public health institutions in five cities, including sustained virological response (SVR) and side effects. Patients with advanced fibrosis (F3/4), moderate fibrosis (F2) for > 3 years, or extra-hepatic manifestations were treated according to Ministry of Health protocol. Treatment effectiveness was verified by using bivariate and multivariate analysis; p-values of < 0.05 were considered significant. RESULTS: Of 275 patients (64.7% men; average age, 57 years old), most (61.8%) were treatment-experienced; 53.9% had subgenotype 1a infection, 85.1% had advanced fibrosis, and 85.5% were treated with telaprevir. SVR was observed in 54.2%. Rapid virological response (RVR) was observed in 54.6% of patients (data available for 251 patients). Overall, 87.5% reported side effects and 42.5% did not complete treatment. Skin rash, severe infection, and death occurred in 17.8%, 2.5%, and death in 1.4% of cases, respectively. SVR was associated with treatment completion, RVR, and anemia. CONCLUSIONS: The effectiveness of hepatitis C virus triple therapy was lower than that reported in phase III clinical trials, possibly owing to the prioritized treatment of patients with advanced liver fibrosis. The high frequency of side effects and treatment interruptions observed supported the decision of the Brazilian authorities to suspend its use when safer and more effective drugs became available in 2015.

OBJETIVO: Investigar os fatores determinantes das mudanças da terapia antirretroviral (TARV) inicial dos pacientes assistidos em hospital de referência em AIDS do Ceará. MÉTODOS: O estudo descritivo e exploratório utilizou a análise dos formulários de solicitação de início ou modificação de tratamento do ano de 2008, acompanhando as mudanças de terapia durante o primeiro ano de tratamento. Os dados foram analisados nos programas Statistical Package for the Social Sciences (SPSS) e Epi Info, utilizando ANOVA e teste exato do coeficiente de contingência, com significância de p < 0,05. RESULTADOS: Dos 301 pacientes que iniciaram TARV, 22,1% (n = 68) realizaram troca no primeiro ano. Os pacientes eram, na maioria, do sexo masculino, de idade entre 20 e 39 anos, e fizeram apenas uma mudança da TARV (86,8%; n = 59). Registros de duas ou três mudanças de esquema foram observados. A zidovudina foi o fármaco mais substituído, seguido por lopinavir/ritonavir e efavirenz. Existiu associação significante entre as trocas dos esquemas iniciais com o relato de ocorrência de reações adversas (p < 0,001). CONCLUSÃO: O principal fator determinante para as mudanças de TARV inicial foi o relato de ocorrência de reações adversas. A maioria dos pacientes fez somente uma mudança na TARV inicial durante o primeiro ano de tratamento. O monitoramento da TARV contribuiu para melhor controle da farmacoterapia específica.
OBJECTIVE: To investigate factors determining changes in initial antiretroviral therapy (ART) in patients attended to in an AIDS tertiary care hospital in Ceará, Brazil. METHODS: This descriptive and exploratory study used the analysis of request to initiate or change treatment forms in the year of 2008, and the changes in therapy were followed through the first year of treatment. Data were analyzed with SPSS and EpiInfo by using ANOVA and the exact test of the coefficient of contingency, with significance at p < 0.05. RESULTS: From 301 patients initiating ART, 22.1% (n = 68) needed a change in the first year. These patients were mostly males, aged 20 to 39 years; with only one ART changed needed in 86.8% of the cases (n = 59). Reports of two or three changes in regimen were observed. Zidovudine was the drug most often changed, followed by lopinavir/ritonavir and efavirenz. A significant association was found between changes in initial regimens and the report of adverse reactions (p < 0.001). Conclusion: The main factor determining changes in the initial ART was an adverse reaction report. Most patients had one change in the initial ART over the first year of treatment. ART monitoring contributed to a better control of the specific drug therapy.

Quatro pacientes HIV positivos com perfil imunologico diferente e portadores de dermatite seborreica(DS) da face forma tratados exclusivamente com pimecrolimus creme, um imunomodulador macrolactamico. O pimecrolimus inibe a calcineurina atraves do complexo droga-macrofilina-12 e desta maneira inibe a ativacao e maturacao das celulas T, bloqueia a ativacao da transccricao dos genes das linfocinas, evita a degranulacao mastocitaria e iniube a funcao das celulas de Langerhans. Nao promove atrofia, estria, foliculite, exacerbacao de acne/rosacea, telangiectasia ou toxicidade ocular permitindo o uso seguro em areas criticas com a face. Os pacientes usaram na face o pimecrolimus 1,0porcento creme duas vezes por dia por sete dias consecuti9vos havendo desaparecimento total das lesoes apos este periodo.
