Overview
The mainstay of treatment for tubulointerstitial nephritis is discontinuation of potentially offending agent. The majority of patients due to drug-induced interstitial nephritis, improve spontaneously with supportive care. However, renal function may not return to baseline. In conditions with persisting renal failure it is recommended to obtain a renal biopsy and trial of glucocorticoids therapy must be considered for patients with AIN on biospy.
Medical Therapy
The mainstay of treatment for tubulointerstitial nephritis is discontinuation of potentially offending agent, as well as following measures:
- Supportive care and maintaining adequate hydration
- Symptomatic relief for fever, rash, and systemic symptoms
- Control of blood pressure
- Correct electrolyte imbalances
- Reduce exposure to other nephrotoxic agents
The majority of patients involved with drug-induced AIN, improve spontaneously, and no additional measures are needed among patients with minimal rise in the serum creatinine or those who show betterment after discontinuation of offending agent; otherwise if renal failure persists after removing the culprit drug, obtaining a renal biopsy and attempt glucocorticoids therapy for patients with biopsy-confirmed AIN must be considered.[1]
Glucocorticoid therapy
- Glucocorticoid therapy is recommended among patients with the critical rise in the serum creatinine, or those whose renal failure persists after removing the offending agents; although before the beginning of glucocorticoid therapy obtaining a kidney biopsy and confirmation the diagnosis is necessary.[2]
- Preferred regimen: Prednisone 1 mg/kg per day PO or equivalent IV dose (maximum of 40 to 60 mg) for a minimum of one to two weeks, by a gradual taper over 3-4 weeks.[3]
- Alternative regimen: In patients who do not respond to corticosteroids within 2-3 weeks, or who are glucocorticoid dependent or glucocorticoid resistant (as with NSAID-induced disease), mycophenolate mofetil may be considered.[4]
