[Etravirine in clinical practice: Experience in 151 non-naïve patients]. / Etravirina en la práctica clínica: experiencia de uso en 151 pacientes pretratados.

BACKGROUND: There are limited data on etravirine (ETV) use in routine clinical practice. METHODS: The reasons, efficacy and tolerability of its use are retrospectively reviewed. RESULTS: Overall, 151patients started a regimen containing ETV. The main reasons for prescription were toxicity and virological failure. After a median follow-up of 16months 76.2% of the patients had an undetectable viral load. Patients with detectable HIV-RNA at baseline had a greater risk of failure (31.7% vs 18%; P=.05). CONCLUSION: ETV is safe, effective and durable.

[Malignancies in HIV infected patients: study of 139 cases]. / Tumores en pacientes con infección por el virus de la inmunodeficiencia humana: estudio de 139 casos.

BACKGROUND AND OBJECTIVE: Since the introduction of highly active antiretroviral therapy (HAART), the natural history of HIV infection has been altered by an increasing survival. Following this, neoplastic diseases have become more common in HIV positive patients. The purpose of this study was to describe the types of tumor, clinical features and prognosis of HIV infected patients with malignant diseases. PATIENTES AND METHODS: A descriptive study of epidemiological and clinical features was undertaken at Hospital Carlos III, in Madrid. Information was collected on age, sex, risk factors for HIV, HBV/HCV coinfection, malignancies, diagnosis of AIDS, viral load and CD4 cell counts at diagnosis, antiretroviral therapy and mortality. A total of 139 HIV-infected patients were identified who had at least one malignancy. Statistical analysis was performed using SPSS 15.0 package. RESULTS: Types of malignancy were Kaposi's Sarcoma (n=43, 30.9%); non-Hodgkin lymphoma (n=42, 30.2%); gynecologic malignancy (n=16, 11.5%); Hodgkin's disease (n=15, 10.8%); hepatocellular carcinoma (n=7, 5%) and others (n=16, 11.5%). Mean age at diagnosis was 40 years (IC 95% 38.51-1.50). Male/female ratio was 3.63. Patients with HBV or HCV coinfection were 1.4% and 35.3% respectively. Risk factor for HIV was MSM (n=64;46%), IDUs (n=48; 34.5%) and heterosexual (n=26; 18.7%). Viral load was undetectable in 27 cases (19.4%); CD4 cell count was<200 cell/mcl in 58 cases (41.7%). There were 77 (55.4%) patients on HAART when cancer was diagnosed. Mean time on HAART was 23.31 months. Ten patients (7.2%) developed a secondary tumor. Twelve years survival was 20%. CONCLUSIONS: Increased survival of HIV-infected patients receiving HAART makes it possible the development of secondary tumors and AIDS- unrelated malignancies, sometimes related to another virus.

[Immigration and HIV-1 infection: clinical manifestations, subtypes and evolution of 78 patients attended during the last 5 years]. / Infección por el virus de la inmunodeficiencia humana tipo 1 e inmigración: manifestaciones clínicas, subtipos y evolución de 78 pacientes ingresados durante los últimos 5 años.

BACKGROUND AND OBJECTIVE: To analyse the characteristics and HIV-1 subtype in a group of HIV+ hospitalised immigrants in our Infectious Diseases Unit. PATIENTS AND METHOD: Clinical reports of 78 immigrants HIV+ were reviewed. HIV-1 subtyping was carried out examining the protease and transcriptase genes by phylogenetic analysis. Statistical study was done by SPSS 11.0 program. RESULTS: 57% of patients come from sub-Saharian Africa. Mainly they had been infected by heterosexual contact. HIV was diagnosed at the hospitalisation time in 35 cases. Only 28% were receiving highly active antiretroviral therapy and 48,7% had CD4+ cells less than 200/microl. The more frequent diagnosed diseases were: tuberculosis (20.5%), candidiasis (24.4%), bacterial pneumonia (19.2%) and malaria (21.8%). HIV-1 subtype B was isolated in 26 patients, none Africans. Twenty nine individuals (52.8%) were infected with HIV-1 non-B subtypes. Relationship between HIV-1 subtype, immunodepression, diagnosed diseases and origin countries was not found apart from malaria. CONCLUSIONS: Most HIV-1 infected immigrants are from Africa, being predominantly infected with HIV-1 non-B subtypes. No relationship between HIV subtype and diagnosed diseases was found.
