Intestinal parasitic infections and associated factors among people living with HIV attending Dessie Referral Hospital, Dessie town, North-east Ethiopia: a cross-sectional study.

INTRODUCTION

Intestinal parasites and HIV/AIDS co-infection become a major public health concern in Africa. The management and care of HIV/AIDS patients is being complicated by intestinal parasitic infections. Therefore, this study aimed to determine the prevalence and associated factors of intestinal parasitic infections among people living with HIV at Dessie Referral Hospital, North-east Ethiopia.

METHODS

This cross sectional study was conducted from March to May 2019. Systematic simple random sampling technique was used to recruit study participants. Stool specimen was collected and examined microscopically using wet mount, formol-ether concentration technique and modified Zeihl-Neelsen methods. Socio-demographic characteristics and associated factors were collected using structured questionnaire. The recent CD4 cell count was obtained from patients ART follow-up record. Data were analysed using SPSS version 20 software. Bivariate and multivariate logistic regression was done to investigate the association between independent and dependent variables.

RESULTS

Of the total of 223 study participants 120 (53.8%) were females and 162 (72.6%) were urban resident. The overall prevalence of intestinal parasites was 47 (21.1%). Eleven different intestinal parasites species were detected. The dominant intestinal parasite species was Entameoba histolytica 14 (6.3%) followed by Enterobius vermicularis 5 (2.2%). Multivariate logistic regression analysis showed that individuals who had a habit of hand washing after latrine were less likely to be infected with intestinal parasitic infection (AOR 0.15, 95% CI 0.05-0.412). On the other hand individuals who had CD cell count of < 200 cells/ml were 45.53 times more likely infected with intestinal parasites.

CONCLUSION

The prevalence of intestinal parasite was higher than previous report from the same study area almost a decade ago. There was statistical significant association between hand washing habit after latrine, habit of eating raw vegetables and CD cell count less than 200 cells/ml and intestinal parasitic infections. Health education program interrupted in Dessie referral hospital should be continued to reduce the prevalence of intestinal parasites. Utilization of water treatment, washing hand after latrine and eating cooked or appropriately washed vegetables should also be promoted. Moreover, periodic laboratory stool specimen examination and prompt treatment are necessary.
