Abstract

Background: Pulmonary tuberculosis is one of the most important health concerns. Pulmonary fungal infections have clinical and radiological characteristics similar to tuberculosis which may be easily misdiagnosed as tuberculosis. This study aimed to evaluate tuberculosis (TB) status and coinfection of TB with pulmonary fungal infections in patients referred to reference laboratory of health centers Ghaemshahr city during 2007-2017.

Methods: This cross-sectional study was conducted during eleven years, between 2007-2017, on 3577 patients with suspected TB referred to health centers of Ghaemshahr City. For isolation, sputum smear preparation and Ziehl-Neelson staining in companying with microscopy direct observation and KOH 10% + white Calcofluor staining was used. The culture of fungi was performed on Sabouraud Dextrose agar, Czapek and chrome agar media. Then, data were analyzed using SPSS software (version 16) through Student's t-test, Fisher test, and Odds Ratio. P values <0.05 were considered statistically significant.

Results: Of 3577 patients, 10731 smears were prepared, 3.6% (n=130) of patients were identified as smear-positive pulmonary tuberculosis, 86.4% (n=3090) were smear negative and 10% (n=357) drug-resistant TB. The mean age of patients was 48±1.8 years. With increasing age, the prevalence of TB has increased which was statistically significant (P value <0.05). Prevalence of tuberculosis in the age group over than 57 years in males and females had an ascending trend. Amongst the positive tuberculosis patients, 16/130 cases (12.3%) had the coinfection of TB with fungi microorganisms.

Conclusion: Our findings showed the coinfection of fungi agents in patients with tuberculosis that should be considered.
