ABSTRACT
Pulmonary tuberculosis [TB] is the most common form of the tuberculosis in HIV infected patients that can affect on progression of HIV infection. The aim of this study was to investigate the impact of HIV infection on the clinical presentation of tuberculosis. We extracted the information of admitted patients in infectious ward of Razi hospital with pulmonary tuberculosis diagnosis from 2004-2009.Outcome of this stage was 204 patients. Then we divided these patients in two groups, group 1 patients with HIV [34 cases] and group 2 without HIV infection [170 cases]. Finally, we compared the clinical manifestations between these two groups. Data analysis with Chi square test and SPSS software was done. Tuberculosis was more common in men in both groups [p<0.001]. The mean age of HIV positive patients was lower than HIV negative patients. [31.85 +/- 8.52 vs. 44. 33 +/- 10.34], [p=0.001]. Fever, weakness and hemoptysis were more frequent in HIV positive patients [%94.11 vs.%81.17,%58.82 vs.%50.58 and%20.58 vs.%7.05], [p=0.07, p=0.23, p=0.01]. Whereas chronic cough, sputum, weight loss and night sweating were more prominent in HIV negative patients. [%95.29 vs.%73.52,%87.64 vs.%70.58,%71.17 vs.%38.23 and%61.76 vs.%41.17], [p=0.03, p=0.04, p=0.009, p=0.04]. According to the study in these two groups it is important to consider tuberculosis in differential diagnosis of every HIV infected patient not only with cough and sputum but also with fever and constitutional symptoms
ABSTRACT
Toxocariasis is a worldwide zoonosis caused by the acaridae of dogs and rarely cats. Seroprevalance of toxocariasis vary with geographic regions. In this study, the sera of school children aged between 6 to 15 years were examined for the presence of anti T.canis antibodies. In this descriptive cross-sectional study the sera of 203 randomly selected school children aged between 6 to 15 years from urban and rural regions in Ahvaz, south western of Iran from 2007 to2008 was examined by means of ELISA with excretory-secretary antigen of infectious larva stage. CBC was performed for the presence of eosinophilia or hypereosinophilia. A short questionnaire was fulfilled to obtain data of age, sex, history of pica, contact with dogs and living area [urban or rural]. Of total 203 students 90 [44.3%]were female and 113 [55.7%] were male. 86 [42.9%] were rural and 114 [57.1%] were urban, 67 [33%] had contact with dogs,35 [17%] had history of recent cough,5 [2.5%] had pica, on had hypereosinophilia but 21 [10.3%] had eosinophlia, 4 [2%] had positive ELISA for T.canis IgG, of them one was male and three were female, two were urban and two were rural, non had history of contact with dogs, pica, chronic cough or asthma, and also non had hypereosinophilia but all had eosinophilia. Our study showed that toxocariasis is present in the school children of Ahvaz, but it is lower than was expected and also lower than similar tropical regions
