Syndrome of inadequate antidiuretic hormone secretion in pulmonary tuberculosis - a therapeutic challenge.

ABSTRACT

A forty-nine-year-old female patient with pulmonary tuberculosis developed syndrome of inadequate antidiuretic hormone secretion. Consequent restriction of fluid intake as a therapeutic measure was just as ineffective as a medication with tolvaptan which was performed later on. A probable explanation for the inefficacy of the aquaretic drug is an interaction of rifampicine and tolvaptan. This case report gives a short summary of SIADH in pulmonary TB and discusses possible reasons for the difficult antituberculotic treatment in this patient.
