BackgroundHIV infection has been modifying both the epidemiology and outcome of parasitic infections. Hence, this study was undertaken to determine the prevalence of intestinal parasitic infection among people with and without HIV infection and its association with diarrhea and CD4 T-cell count.MethodsA cross-sectional study was conducted at Hawassa Teaching and Referral Hospital focusing on HIV positive individuals, who gave blood for CD4 T-cell count at their first enrolment and clients tested HIV negative from November, 2008 to March, 2009. Data on socio-demographic factors and diarrhea status were obtained by interviewing 378 consecutive participants (214 HIV positive and 164 HIV negative). Stool samples were collected from all study subjects and examined for parasites using direct, formol-ether and modified acid fast stain techniques.ResultsThe prevalence of any intestinal parasitic infection was significantly higher among HIV positive participants. Specifically, rate of infection with Cryptosporidium, I. belli, and S. stercoralis were higher, particularly in those with CD4 count less than 200 cells/μL. Diarrhea was more frequent also at the same lower CD4 T-cell counts.ConclusionImmunodeficiency increased the risk of having opportunistic parasites and diarrhea. Therefore; raising patient immune status and screening at least for those treatable parasites is important.

Background: This study was done to identify risk factors that affect the morbidity and mortality of patients operated for a perforated peptic ulcer in a resource-limited setting.Methods: A two years (January 1, 2016 - December 30, 2018) retrospective cross- sectional study was done on patients admitted and operated for PPU at Yekatit 12 Hospital, Addis Ababa,Ethiopia.Results: A total of 93 patients were operated. The median age affected was 29 years (Range 15-75 years). Male to female ratio was 7.5:1. Chewing chat, smoking and alcohol use were seen in 22 (23.6%), 35(37.6%), and 34(36.5%), cases respectively. Only 23.6% gave previous history of dyspepsia. The median duration of illness was 48hours and the duodenal to gastric ulcer perforation ratio was 6.5:1. In majority of the cases (63.3%) the perforation diameter was <10mm (63.3%). Cellan-Jones repair of the perforations was done in 92.5% of cases. A total of 47 complications were seen in 25 cases. The total complications and mortality rates were 25(26.8%) and 6(6.5%) respectively. The most common postoperative complication was pneumonia (13.97%) followed by superficial surgical site infection (10.8%). Mortality rate was highest among patients >50yrs [AOR (95%CI) =2.4(2-30)]. Delayed presentation of >24 hours [AOR (95%CI) =4.3(1.4-13.5)] and a SBP <90mmhg [AOR (95%CI) =4.8(1-24)] were found to be significantly related with higher complication rate.Conclusions: Patients who presented early and immediate corrective measures were instituted had better outcomes while those seen late developed unfavorable out-come with significantly higher complications. Therefore, early detection and treatment of PPU is essential.
