[CCR5-Δ32 allele involvement in the clinical evolution of HIV1+ patients in Yucatán, Mexico].

Objective: CCR5-Δ32 allele frequency needs to be identified in HIV+ patients and exposed seronegative individuals in Yucatan, Mexico, to understand this mutation's relationship to infection and disease progression.

Material And Methods: A total of 355 samples were analyzed: 62 from HIV+ patients, 51 from exposed seronegative individuals and 242 from general population. Infected patients were subdivided into a) normal progressors n= 49; b) slow progressors n= 10, and c) non-progressors n= 3.

[Hyperlipidemia and glucose intolerance in patients with HIV infection receiving antiretroviral therapy].

Objective: To determine the prevalence of secondary effects on lipid metabolism as a result of highly active antiretroviral therapy (HAART), as well as the impact of different types of antiretroviral regimens on lipids and glucose in a group of patients in Yucatan, Mexico.

Material And Methods: A cross-sectional study was conducted. A questionnaire created for this study was administered to each patient and total cholesterol, triglycerides and fasting glucose values were determined.

Co-infection by the human T-cell lymphotropic virus type II in patients infected by the human immunodeficiency virus in Yucatan, Mexico.

Background: The HTLV-II infection has been reported in patients with HIV infection as often in asymptomatic as those with acquired immunodeficiency syndrome (AIDS). The aim of this study was to determine the prevalence of HTLV-II infection in a group of patients infected by HIV in our region, as well as determining the risk factors associated with HTLV-II transmission in this group of patients and its impact on the clinical course of HIV infection.

Methods: A cross-sectional study was carried out to determine the prevalence of co-infection of HIV-1 and HTLV-II among 192 patients from Yucatán, México.

[Acceptability of a test for antibodies against HIV in a group of pregnant women in Yucatan, Mexico].

Patients And Methods: A clinical and epidemiological study was carried out on 310 pregnant women at different health centers in Yucatan Mexico, from January 2000 to March 2001. A questionnaire was applied to determine information in relation to HIV infection and acceptability of the test.

Frequency of antibodies against the hepatitis C virus in patients with hepatic cirrhosis in Yucatan, Mexico.
