Tuberculosis-Associated Chronic Kidney Disease
ABSTRACT Extrapulmonary tuberculosis (TB) account for approximately 15-20% of TB cases in immunocompetent patients. The genitourinary system is the third most commonly affected site. We report the case of a 20-year-old man admitted with fever, chills, dry cough, right flank pain, and oliguria who developed renal function loss. The pyelogram evidenced silence of the right kidney, and the abdominal and pelvic magnetic resonance showed significant dilation of the right pyelocaliceal system and proximal ureter. Biopsies of renal cortex and retroperitoneal lymph nodes showed caseous granuloma consistent with TB. Treatment was started with rifampicin, isoniazid, pyrazinamide, and ethambutol, and the patient presented a favorable outcome but with non-dialytic chronic kidney disease. This case illustrates a case of chronic kidney disease secondary to TB in a young, otherwise healthy man.

ABSTRACT: Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis. The disease remains as an important public health problem in developing countries. Extrapulmonary TB became more common with the advent of infection with human immunodeficiency virus and by the increase in the number of organ transplantation, which also leads to immunosuppression of thousand of persons. Urogenital TB represents 27% of extrapulmonary cases. Renal involvement in TB can be part of a disseminated infection or a localized genitourinary disease. Renal involvement by TB infection is underdiagnosed in most health care centers. Most patients with renal TB have sterile pyuria, which can be accompanied by microscopic hematuria. The diagnosis of urinary tract TB is based on the finding of pyuria in the absence of common bacterial infection. The first choice drugs include isoniazide, rifampicin, pirazinamide, ethambutol, and streptomycin. Awareness of renal TB is urgently needed by physicians for suspecting this disease in patients with unexplained urinary tract abnormalities, mainly in those with any immunosuppression and those coming from TB-endemic areas.The American journal of tropical medicine and hygiene 01/2013; 88(1):54-64.

ABSTRACT: Hypercalcemia caused by tuberculosis is rare, and it is usually asymptomatic. Tuberculosis (TB) -related hypercalcemia associated with acute kidney injury (AKI) is rarely reported. We report a case of a 22-year-old immunocompetent man with 1-month history of daily fever, asthenia, and weight loss. Laboratory findings on admission included serum calcium = 14.9 mg/dL, urinary Ca(2+) = 569.6 mg/24 hours, low level of parathyroid hormone, serum creatinine = 2.2 mg/dL, and sodium fractional excretion (FeNa) = 2.73%. The result of the tuberculin skin test was 17 mm. A chest X-ray revealed micronodular pulmonary infiltrate in the apex of the right lung, which was confirmed by computed tomography scan. The patient was diagnosed with hypercalcemia associated with pulmonary TB and AKI. A general improvement of the hypercalcemia and renal function was observed in the first 2 weeks after effective hydration and treatment of TB without corticosteroids. The patient was discharged with normal calcium levels and renal function.The American journal of tropical medicine and hygiene 01/2013; DOI:10.4269/ajtmh.11-0768 · 2.74 Impact Factor
