Intestinal Protozoa, Helminth Infection, and Associated Factors among Tuberculosis Patients and Nontuberculosis Persons in Bobo-Dioulasso City, Burkina Faso.

Abstract

We report the frequency and associated factors of tuberculosis (TB) and parasite coinfection from newly diagnosed pulmonary TB patients (TB+) and non-TB participants (TB-) from the Regional Tuberculosis Control Center, households, and health facilities in Bobo-Dioulasso from 2019 to 2021. Biological samples were examined for parasite infection using direct microscopy, concentration techniques, and the immunochromatographic rapid test. Data were analyzed using STATA 14. Of a total of 192 participants involved, 95 were TB+ and 97 were non-TB. There was no statistically significant difference in parasitic infections between the two groups, although it was higher in TB+ than TB- (69.5% [66/95] versus 55.7% [54/97]; P = 0.07). Protozoal infection prevalence was significantly higher in patients with TB+ than in those TB- (61.1% versus 37.1%; P = 0.001). Specifically, Entamoeba spp. and Cryptosporidium spp. followed this pattern with 35.8% versus 19.6% (P = 0.01) and 22.1% versus 8.3% (P = 0.007), respectively. Although higher in TB+ patients, helminthiasis frequency was not significantly different between the two groups (23.2% versus 15.5%; P = 0.2). Helminth species were Schistosomia mansoni (17.9% versus 12.4%), Dicrocoelium dendriticum (3.2% versus 1.0%), Enterobius vermicularis (2.1% versus 2.1%), Wuchereria bancrofti (1.1% versus 0.0%), and Hymenolepis nana (1.1% versus 0.0%). Illiteracy (adjusted odds ratio [aOR]: 2.5; 95% CI: 1.0-6.1), smoking (aOR: 2.4; 95% CI: 1.1-5.3), and handwashing after defecation (aOR: 2.4; 95% CI: 1.2-4.7) were associated with parasites. This study reported a high frequency of parasite coinfection in TB patients. These findings suggest the need for adequate health education for behavioral change and systematic diagnosing of parasites in TB patients for better coinfection management.
