Abstract

BACKGROUND: The treatment of latent tuberculosis infection (LTBI) among high-risk populations is an essential component of Tuberculosis (TB) elimination. However, non-compliance with LTBI treatment remains a major obstacle hindering TB elimination efforts. We have previously reported high treatment compliance with nurse-managed, twice-weekly, directly observed Isoniazid treatment (DOT) for LTBI among hard-to-reach Ethiopian immigrants (EI's).

OBJECTIVES: to compare rate of completion of treatment, cost, and major adverse drug events with daily self-administered Isoniazid treatment (SAT) to nurse-managed Isoniazid DOT among hard-to-reach EIs.

MATERIALS AND METHODS: We conducted a retrospective study and compared self-administered LTBI treatment outcomes among EIs housed in reception centers during 2008-2012 to EIs treated with DOT.

RESULTS: Overall, 455 EIs were included (231 DOT, 224 SAT) in the study. We found no significant difference in treatment completion rates between the two groups (93.0% DOT vs. 87.9% SAT, p = 0.08). However, cases of grade III, drug-induced hepatitis were significantly fewer and treatment costs were significantly lower with the nurse-managed DOT compared with SAT (0% vs. 2.2%, p = 0.028, 363 vs. 521 United States Dollars, p < 0.001, respectively).

CONCLUSIONS: Nurse-managed, twice-weekly DOT among hard-to-reach EIs housed in reception centers had less severe drug-related adverse events and reduced treatment cost compared with daily isoniazid SAT, yet we found no significant difference in treatment completion between the two strategies in this population.
