Prevalence and Associated Risk Factors of Intestinal Parasitic Infections among Patients Visiting a Referral Hospital in Tehran Province, Iran
Intestinal parasitic infections (IPIs) are still considered a public health problem of mankind, particularly in immunocompromised patients. We aimed to determine the prevalence of IPIs with an emphasis on immunocompromised patients in a referral hospital in Tehran Province, Iran.
In this cross-sectional study, 442 fecal specimens were collected randomly from patients, referred to Baqiyatallah Hospital in Tehran Province, Iran from May to September 2020. The collected specimens were examined using wet-mount, trichrome and modified Ziehl-Neelsen staining, formalin-ether concentration, and agar plate culture.
The prevalence of IPIs was found 17.0% (95% CI: 13.6-20.8%). The prevalence of protozoan parasites (16.3%; 95% CI: 13.0-20.1%) was significantly higher than helminthic parasites (0.7%; 95% CI: 0.1-2.0%). Blastocystis spp., Giardia lamblia, and Entamoeba coli were the most common intestinal protozoan with a prevalence of 12.2%, 1.6%, and 1.4%, respectively. E. histolytica/E. dispar/E. moshkovskii, Iodamoeba bütschlii, Cryptosporidium spp., Chilomastix mesnili as protozoan species and Hymenolepis nana, Dicrocoelium dendriticum, and Ascaris lumbricoides as helminthic species were the other detected parasites. Multiple logistic regression revealed a significant association of IPIs infections with stool consistency and the status of immune system.
The prevalence of IPIs among the patients who are immunocompromised was significantly higher than immunocompetent patients (P< 0.05). Periodic stool examinations for screening of IPIs should be included as a part of routine medical check-up in these patients.
