Prevalence of smear positive pulmonary tuberculosis in Gondar prisoners, North West Ethiopia

Objective: To assess the prevalence and risk factors of smear positive pulmonary tuberculosis among Gondar town prisoners, North West Ethiopia. Methods: A cross sectional study was conducted from February to July, 2008 in Gondar Prison. Prisoners with cough duration of more than two weeks were involved in the study by giving three sputum samples and filling the questionnaires prepared for risk factor assessment. Acid fast staining technique was employed to detect the presence of the Mycobacterium tuberculosis bacilli in the sputum samples. Data was analyzed using SPSS version13 computer software and presented in table. Chi-square test was used to assess associations and a P-value less than 0.05 was taken as significant. Results: A total of 384 prisoners, 349 male and 35 females, with a mean age of 33.3 years were involved in the study. The prevalence of smear positive pulmonary tuberculosis among those prisoners with cough duration of more than two weeks was 8.59%. Only the length of imprisonment had a significant association (χ 2= 18.82, P-value<0.0001) with the prevalence of tuberculosis. Conclusions: This study indicated that tuberculosis among prisoners with cough duration of more than two weeks in Gondar prison is very high. Therefore Periodic screening of the prisoners and screening of newly introduced prisoners should be practiced so as to minimize the burden of tuberculosis in prisoners.

Characteristics of bacterial sepsis among patients with visceral leishmaniasis

Sepsis is one of the major causes and predictors of death in patients with visceral leishmaniasis (VL). Globally, incidence rate of sepsis ranged from 56-91 cases per 100 000 people, with a mortality rate of 30%. Incidence of sepsis has been raised due to aging of the population and the higher incidence of immunosuppressive conditions such as HIV, VL and others. The prevalence of sepsis was reported from 4.2% to 32.3% and 14.1% in VL and VL-HIV coinfected patients, respectively. The mortality rate of VL patients with sepsis is greater than 50%. Factors associated with sepsis in VL patients are immune suppression, pancytopenia, HIV co-infection, age 40 years old, indwelling of central venous lines and hospitalization. Although antimicrobial susceptibility patterns were not well reported, both Gram-positive and Gram-negative bacteria were isolated from patients with VL. So far, limited information is available on sepsis in VL, especially in VL-HIV coinfected patients. Therefore, further studies about sepsis prevalence, causative agents and their antibiotic patterns, and associated factors among VL and VL-HIV coinfected patients are necessary. This review provides information about bacterial sepsis in patients with VL.
