Side-effects of antituberculosis drug treatment in patients with chronic renal failure

Patients with chronic renal failure (CRF) have a high incidence of tuberculosis (TB). Those from the Indian subcontinent are at particular risk. The frequency of side-effects associated with antituberculous treatment in a group of patients with CRF was studied. All cases of TB in patients with CRF occurring over a 13‐yr period at the Manchester Royal Infirmary, from 1986–1999, were identified by diagnostic coding, microbiology records and a TB database. The case notes were then reviewed. Twenty-four cases were identified, eight predialysis and 16 requiring regular dialysis. TB occurring in the dialysis group was extrapulmonary in every case. Nineteen of 24 (79%) patients were of Indian subcontinent origin and 14 of 16 (87%) dialysis patients were non-Caucasian. Adverse effects of treatment occurred in two of eight (25%) in the predialysis group and nine of 16 (56%) of the dialysis group. These were most commonly neuropsychiatric (6), hepatic (4) and gastrointestinal (4). Neuropsychiatric symptoms occurred exclusively in dialysis patients. In conclusion, a high incidence of side-effects from antituberculous medication, especially neuropsychiatric, hepatic and gastrointestinal, was identified in patients with chronic renal failure. Careful monitoring for side-effects is essential in this group, and consideration should be given to administering antituberculous chemoprophylaxis to all high-risk groups.
