ABSTRACT

Background: Tuberculosis (TB) remains one of the most important infectious dise­ases worldwide. Latent TB occurs when a person has the TB bacteria within their body, but the bacteria are present in very small numbers.Tuberculosis in end-stage renal di­se­ase patients on regular hemodialysis (HDPs) presents a number of diagnostic cha­lle­nges.This study aimed to investigate the risk factors of latent tuberculosis among he­mo­­dialysis patients.

Subjects and Method: This was a cross sectional study carried out at Dr. Moewardi Hos­­pital, Surakarta, Central Java, in May 2018. A total of 30 patients was selected for this study. Latent tuberculosis was measured by recorded baseline data, tuberculin skin test (TST), and T-SPOT.

Results: 23.3% patients were latent tuberculosis, 20% had positive TST, and 16.7% had T-SPOT.TB positive. Hemodialysis was significantly associated with positive TST re­­sults (OR= 0.04; 95% CI=0.01 to 0.89; p=0.042). Gender, age, body mass index (BMI), comorbidities, TB contacts, Bacille Calmette Guerin (BCG), duration of hemo­di­al­ysis, and the number of T lymphocyte cells cluster of differentiation 4+ (CD4+) were not significantly associated with latent tuberculosis.

Conclusion: Hemodialysis is significantly associated with positive TST results.
