BACKGROUND: People with Latent tuberculosis infection (LTBI) remain the reservoir of tuberculosis. One-third to 1/4 of the world's population is infected. Its reactivation is due to factors that disrupt the host's immune response. Recent findings showed that Schistosoma mansoni coinfection leads to a Th2/Th1 profile which results in an immune modulation that favors the escape of the Mycobacteria. Schistosoma mansoni may contribute to TB incidence in endemic regions. We aimed to investigate the co-infection rate and patient outcomes.
METHODS: A prospective cohort study was conducted between 2020-2022 at University Clinical Research Center (UCRC), including culture-confirmed active pulmonary TB patients and tested for Schistosoma mansoni in stools using Kato-Katz Technique. After descriptive analysis a logistic regression was performed to determine risk factors associated with TB and Schistosoma mansoni co-infection.
RESULTS: Data of 174 tuberculosis-confirmed patients, Kato-Katz tested were analyzed. Males represented 62.6%, mean age was 34.9 ± 13.8 years, 29.9% were smokers, alcohol consumption 13.8%, TB contact history 26.4%, HIV coinfection 11.5%, diabetes 6.3%, undernourished 55.7%. Schistosoma mansoni prevalence was 28.7%. The co-infection was associated with less lung cavitation [aOR = 0.24 [95% CI (0.06-0.85), p = 0.028], unfavorable treatment result [aOR = 2.95 (1.23-7.08), p = 0.015] and death [aOR = 3.43 (1.12-10.58), p = 0.032].
CONCLUSIONS: Despite Kato-Katz's low sensitivity, Schistosoma mansoni coinfection was found in one-third of the TB patients; 2.5-fold higher than that of HIV. The coinfection was associated with poor treatment results and death.
