Background: Mycobacterium tuberculosis (M. tuberculosis) and Mycobacterium leprae (M. leprae) are morphologically, immunologically, and pathologically similar. The incidence of simultaneous tuberculosis (TB) and leprosy is still controversial. The aim of this study was to detect anti-phenolic glycolipid-I (anti-PGL-I) antibody in sera from TB patients at Dr. Hasan Sadikin Hospital Bandung, West Java, Indonesia. The aim of this study is to detect anti-phenolic glycolipid-I (anti-PGL-I) antibody in sera from TB patients at Dr. Hasan Sadikin Hospital Bandung, West Java, Indonesia. Methods: We performed a cross-sectional descriptive study with consecutive sampling from 112 TB patients clinically diagnosed by internist from the Internal Medicine Department and confirmed through bacteriological, histological, and chest radiograph examinations. The specimens were taken from the blood serum of the patient. Furthermore, the anti-PGL-I immunoglobulin (Ig) M and IgG serum level were evaluated using the enzyme-linked immunosorbent assay. Results: The mean of anti-PGL-I IgM and IgG serum levels in TB patients of this study was 34.17 ± 21.94 pg/ml and 41.44 ± 18.93 pg/ml with the mean of optical density values was 0.18 ± 0.05 and 0.26 ± 0.07. The seropositivity of anti-PGL-I in TB patients was 27.68% for IgM and 41.96% for IgG. The seropositivity of anti-PGL-I IgM and IgG level based on clinical manifestation of TB in this study from the highest to the lowest were as follows: extrapulmonary TB patients (61.29% and 59.57%), pulmonary TB patients (29.03% and 36.17%), and pulmonary with extrapulmonary TB patients (9.68% and 4.26%), respectively. Conclusion: The seropositivity of anti-PGL-I antibody in sera from TB patients in Bandung, West Java, Indonesia was 27.68% for IgM and 41.96% for IgG. Furthermore, periodic observations are needed to determine the likelihood of clinical manifestation of leprosy in TB patients.
