Association between CD4 lymphocyte count and the incidence of comorbidities in Human immunodeficiency virus positive patients with virological suppression after antiretroviral treatment.

Background: The incidence of comorbidities is higher in HIV-positive patients than in the general population due to factors, such as HIV-related chronic inflammation. There is no consensus on whether a low CD4 lymphocyte count after virological suppression at long-term follow-up increases the risk of comorbidities. This study evaluates the association between CD4 lymphocyte count and the incidence of comorbidities during the first 5 years of virological suppression after highly active antiretroviral treatment.

Comparison of the QuantiFERON-TB and tuberculin skin test for detection of latent tuberculosis infection in cancer patients in a developing country.

Cancer patients have an increased risk of reactivation of latent tuberculosis infection. It is unknown which strategy on screening should be used in this population in developing countries. We aimed to determine the concordance between the tuberculin skin test (TST) and QuantiFERON-TB (QFT) assay in order to diagnose latent tuberculosis infection in cancer patients.
