Tyrosine kinase inhibitors (TKIs) are targeted therapy drugs that selectively inhibit protein kinases. Nephrotoxicity associated with TKIs is uncommon. We report a case of a 39-year-old man with acute kidney injury that developed after nilotinib treatment for chronic myeloid leukemia (CML). The renal function of the patient decreased during treatment with nilotinib but improved when treatment was discontinued due to neutropenia. However, the renal function of the patient deteriorated again with the reintroduction of nilotinib for treatment. A renal biopsy revealed acute interstitial nephritis (AIN). The patient had no history of comorbidities and medication causing renal injury. Finally, we diagnosed the patient with nilotinib-induced AIN. After switching to imatinib mesylate, the renal function of the patient stabilized without further deterioration. Our case indicates that nilotinib can be a potential cause of renal dysfunction by inducing AIN when renal function deteriorates in patients treated with nilotinib.

Distinguishing between late-onset TINU syndrome and drug-induced AIN remains difficult given that patients with TINU syndrome may develop uveitis long after the onset of AIN. Therefore, ophthalmic examination is required not only upon diagnosis but also continuously or when eye symptoms, and relapse of urinary findings are observed.

Abstract IgG4-releated disease is typically associated with interstitial nephritis, but rare cases of idiopathic membranous nephropathy as renal manifestation have been described. Obinutuzumab was successfully used in refractory membranous nephropathy, but evidence for the treatment of IgG4-related disease with obinutuzumab is lacking so far. We report one patient's case with membranous nephropathy associated with IgG4-related disease, who was treated with obinutuzumab following anaphylactic reaction to rituximab. Obinutuzumab treatment resulted in a sustained complete remission of membranous nephropathy and decrease of IgG4 to the normal range. This case demonstrates that membranous nephropathy associated with IgG4-related disease can successfully be treated with obinutuzumab.
