Cutaneous manifestations in HIV seropositive male prisoners in Kermanshah

Background: To get accustomed with cutaneous manifestations related to AIDS is effective in early diagnosis of this disease. Objective: To evaluate the cutaneous manifestations in HIV seropositive patients. Patients and Methods: A prospective, descriptive and cross-sectional study was performed on HIV-positive male prisoners in Kermanshah central prison and in addiction camp, referred to skin d...

Haptoglobin polymorphism and iron homeostasis.

BACKGROUND There is a marked difference in the degree of expression of the homozygous C282Y HFE genotype that is associated with hereditary hemochromatosis. It has been reported that individuals with the haptoglobin 2-2 type manifest increased iron concentrations, including serum iron, transferrin saturation, and ferritin. METHODS We studied 232 patients, 115 homozygous for the c.845G-->A (C2...

Enteric viruses in HIV-1 seropositive and HIV-1 seronegative children with diarrheal diseases in Brazil

Diarrheal diseases (DD) have distinct etiological profiles in immune-deficient and immune-competent patients. This study compares detection rates, genotype distribution and viral loads of different enteric viral agents in HIV-1 seropositive (n = 200) and HIV-1 seronegative (n = 125) children hospitalized with DD in Rio de Janeiro, Brazil. Except for group A rotavirus (RVA), which were detected ...

Analysis of haptoglobin phenotype polymorphism in a Mennonite population of northern Mexico.

Factors influencing T-cell turnover in HIV-1-seropositive patients.

HIV-1 disease is associated with pathological effects on T-cell production, destruction, and distribution. Using the deuterated (2H) glucose method for endogenous labeling, we have analyzed host factors that influence T-cell turnover in HIV-1-uninfected and -infected humans. In untreated HIV-1 disease, the average half life of circulating T cells was diminished without compensatory increases in...
