          Abstract

          ABSTRACT Introduction: Rifampin is a cornerstone for the first phase of the treatment of pulmonary tuberculosis. This report presents the case of a patient with allergic tubulointerstitial nephritis (ATIN) due to rifampin, situation that has not been reported in Colombia. Case presentation: A male patient with a history of pulmonary tuberculosis treated with rifampin developed acute kidney injury. On admission, no evidence of abnormalities or history to explain the injury was found, but he did present tubular acidosis and associated Fanconi syndrome. The kidney injury was temporarily consistent with rifampicin use, and a kidney biopsy confirmed ATIN. The drug was suspended, resulting in improved kidney function. Discussion: ATIN as a side effect of rifampin is a scarcely reported disease. The risk of developing this condition should be considered when starting and restarting treatments with this medication. Conclusion: ATIN is one of the side effects of tuberculosis treatment. Albeit rare, it should be considered when starting tuberculosis medications.

          RESUMEN Introducción. La rifampicina es un medicamento fundamental en la primera fase del tratamiento en la tuberculosis pulmonar; sin embargo, esta puede causar nefritis tubulointersticial aguda (NTIA) en raras ocasiones. Presentación del caso. Paciente masculino con antecedentes de tuberculosis y en tratamiento con rifampicina, quien desarrolló lesión renal aguda. Al ingreso, el sujeto no registró anormalidades o antecedentes que explicaran lesión renal, pero sí presentaba acidosis tubular y síndrome de Fanconi asociado. La lesión renal concordó temporalmente con el uso de rifampicina y una biopsia de riñón confirmó NTIA. Se ordenó suspender el medicamento, con lo cual la función renal mejoró. Discusión. La NTIA como un efecto secundario de la rifampicina es una enfermedad poco reportada, por tanto, al iniciar y al reiniciar el manejo con este medicamento se debe tener en cuenta el riesgo de desarrollarla. Conclusión. La NTIA es uno de los efectos secundarios del tratamiento de la tuberculosis y, aunque es raro, debe tenerse en cuenta al iniciar el esquema de medicamentos para la tuberculosis.

            Tubulointerstitial nephritis: diagnosis, treatment, and monitoring.

            Tubulointerstitial nephritis (TIN) is a frequent cause of acute kidney injury (AKI) that can lead to chronic kidney disease (CKD). TIN is associated with an immune-mediated infiltration of the kidney interstitium by inflammatory cells, which may progress to fibrosis. Patients often present with nonspecific symptoms, which can lead to delayed diagnosis and treatment of the disease. Etiology can be drug-induced, infectious, idiopathic, genetic, or related to a systemic inflammatory condition such as tubulointerstitial nephritis and uveitis (TINU) syndrome, inflammatory bowel disease, or immunoglobulin G4 (IgG4)-associated immune complex multiorgan autoimmune disease (MAD). It is imperative to have a high clinical suspicion for TIN in order to remove potential offending agents and treat any associated systemic diseases. Treatment is ultimately dependent on underlying etiology. While there are no randomized controlled clinical trials to assess treatment choice and efficacy in TIN, corticosteroids have been a mainstay of therapy, and recent studies have suggested a possible role for mycophenolate mofetil. Urinary biomarkers such as alpha1- and beta2-microglobulin may help diagnose and monitor disease activity in TIN. Screening for TIN should be implemented in children with inflammatory bowel disease, uveitis, or IgG4-associated MAD.
