Renal Effects after Pembrolizumab Treatment for Non-small Cell Lung Carcinoma

Abstract: Immune checkpoint inhibitors (CPIs), including pembrolizumab, are becoming common oncological treatments. CPIs have been associated with a significant risk of developing immune-related adverse events (irAEs), such as nephritis and interstitial nephritis. However, the occurrence of glomerulonephritis has only rarely been reported. We herein present the case of a 75-year-old woman with non-small cell lung carcinoma (NSCLC) who developed proteinuria and microscopic hematuria during treatment with pembrolizumab. R… Show more

“…9 It is known that tubulointerstitial injuries can occur secondary to various conditions, other than induced by pembrolizumab, including IgA nephropathy and arteriolosclerosis. 10 Nephrologists identified both conditions and ruled them out in this patient, however the proteinogram and urine sediment were normal. The patient was not biopsied, but he was diagnosed with interstitial nephritis as the most likely event.…”

“…8 On the one hand, there is no clear consensus on the effectiveness of steroid therapy for ATIN, due to the fact that there have been no randomized, controlled studies. 10 On the other hand, according to the pharmaceutical reference of pembrolizumab (KEYTRUDA), only if creatinine levels are elevated to grade III (serum creatinine >3.0Âbaseline), treatment with systemic steroids, such as prednisolone (1-2 mg/kg), will be recommended. 1 In our case, creatinine levels elevated >3.0 Âbaseline.…”

“…Since the Food and Drug Administration (FDA) approved it in 2011, there were only four cases of biopsyproven CPI-associated IgA nephropathy and all were described with programmed death-1 (PD-1) inhibitors use. [5][6][7][8] In comparison, there were more reported cases of MCD and they were in association with both cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and PD-1 antibodies. 9 The degree of proliferative changes on biopsy, proteinuria, treatment, and the outcome of these cases were variable.…”
