Diagnosis and therapy for prostate tuberculosis

Abstract

In its 2012 global report on tuberculosis, the World Health Organization estimated that 3-7% (range 2.1-5.2%) of new cases and 20% (range 13-26%) of previously treated cases had multidrug-resistant tuberculosis (defined as tuberculosis caused by Mycobacterium tuberculosis isolates that are resistant to rifampicin and isoniazid). In many countries in Eastern Europe and central Asia, 9-32% of new patients and more than 50% of previously treated patients have multidrug-resistant tuberculosis. Ninety-three patients with suspected prostate tuberculosis were enrolled in this study and all underwent prostate biopsy. This method allowed confirmation of diagnosis in 32 patients (34.4%): 23 by histology, six by culture and five by polymerase chain reaction (PCR) (among them, two also had positive culture). The efficiency of an optimized scheme for the therapy of prostate tuberculosis (the second part of the study) was estimated in 53 patients. The first group (25 patients) was treated with a standard scheme of chemotherapy; the second group (28 prostate tuberculosis patients) received ofloxacin in addition for 2 months during the intensive phase. The phase continuation in both groups was identical, with rifampicin and isoniazid administered for 6 months. Optimization of the standard therapy by additional administration of ofloxacin improved results of the treatment in 33.8% of patients.
