Tuberculosis (TB) is one of the oldest diseases known to affect humans, it caused by infection with Mycobacterium Tuberculosis (MTB). MTB is most commonly transmitted from a patient with infectious pulmonary TB to other person by droplet nuclei. End Stage Renal Disease (ESRD) patients are exposed to a variety of infections, including TB. The standard test for detecting Latent TB infection (LTBI) is tuberculin skin test (TST).
Determination the prevalence of latent tuberculosis among end stage renal disease patients in hemodialysis unit in Baghdad teaching hospital, and assessing its correlations with various conditions.
A stratified random sampling technique was used to select a sample of 71 patients of ESRD in hemodiaylsis unit in Baghdad teaching hospital. The selected patients were interviewed using a structured pretested questionnaire.
Two units of PPD (0.1mL) had been injected intradermally to the volar surface of forearm to be seen within 48-72 hours. The test was considered positive if (>=10mm induration) developed.
The study showed the rate of tuberculin reactivity among End Stage Renal Disease (ESRD) patients is 28.57%. About 57.14% of patients were male; mean age of patient was 54.34 ± 15.25 years. The major cause of renal impairment were diabetes mellitus (DM) 52.86%, followed by hypertension 15.71%, duration of dialysis more than 6 months was 46.67% .
History of contact with active tuberculosis patient was 62.5%.
Significant relationship between history of contact with active TB patients, duration of dialysis, and age of patients with TST positivity.
