Anti-tuberculosis prophylaxis following renal transplantation: acceptable variations?
BACKGROUND
Guidelines suggest tuberculosis (TB) prophylaxis in renal transplant recipients originating in endemic areas or in those at risk from non-endemic countries. Concern remains that these guidelines may fail to provide adequate prophylaxis for a cohort of patients who remain at potential risk. We aimed to determine variation patterns among different transplant units within the United Kingdom (UK) with regard to TB prophylaxis policy.


METHODS
The renal pharmacist at each of the 25 UK renal transplant centers was contacted. Specific information was obtained relating to drug prophylaxis given, duration of treatment, as well as which transplant recipients were eligible for treatment.


RESULTS
A 96% response rate (24/25 centers) was achieved. Prophylaxis regimens varied from no prophylaxis to isoniazid 300 mg given life-long. The most common duration of treatment was 6 months post transplantation (at 7 centers). Variations existed in the concurrent use of pyridoxine. A wide discrepancy was seen in the determination of who should receive prophylaxis, with no clear association with frequency of TB incidence in the region.


CONCLUSIONS
A marked discrepancy exists among national renal transplant units in pharmacologic prophylaxis for TB, as well in the selection of individuals for this treatment.
