| From the beginning of the AIDS epidemic, pneumocystis pneumonia (PCP) has been distinguished as one of the most frequent opportunistic diseases with high morbid-mortality. As from 1996, the advent of the highly active antiretroviral therapy (HAART) has changed the characteristics of such epidemic by reducing its related diseases and, as a result, AIDS-related mortality. With the purpose to estimate PCP occurrence and HAART interference, 376 HIV-infected or AIDS patients were studied from January 1992 to December 2002. Among them, 58 (15.5%) PCP cases were found. There was a higher occurrence of PCP in the group of patients in which HAART was not used, with 40 (69.0%) of the episodes. As regards the studied period, a tendency to a linear reduction in annual... |

| The aim of this study was to evaluate the alveolus-capillary permeability by the lung clearance rate of 99mTc-DTPA(Technetium99m-diethylene triamine penta-acetate), (LCR-DTPA), both in normal and in asymptomatic HIV seroreactive patients. Thirty individuals were studied, 21 seronegative normal volunteers and 9 HIV seroreactive patients presenting normal chest radiography and no respiratory infection symptoms. LCR-DTPA was determined by inhaling 99mTc-DTPA and obtaining images in a gamma camera. The 99mTc-DTPA clearance rate in normal individuals was 0.99±0.15%.min-1 and in patients 2.31±1.25%.min-1. There was a significant statistical difference between the two groups (p< 0.05). Two patients who presented LCR-DTPA higher than 4.3 %.min-1 presented... |
