Hematopoietic cell transplantation-associated renal injury may be related to a combination of factors including chemotherapy, radiation, infection, immunosuppressive agents, ischemia, and graft-versus-host disease. Renal biopsy specimens from hematopoietic cell transplant recipients at two institutions (Stanford University Medical Center and Oregon Health & Science University) were reviewed in correlation with clinical data. Fifteen cases were identified (post hematopoietic cell transplant time 0.7-14.5 years), including six with autologous hematopoietic cell transplant. Indications for renal biopsy included proteinuria (n=13; nephrotic range in 8), increased serum creatinine (n=10), or both (n=6). Many patients had multiple pathologic findings on renal biopsy. Membranous glomerulonephritis was the most common diagnosis (n=7), including two patients with autologous hematopoietic cell transplant and five with evidence of chronic graft-versus-host disease elsewhere. Four membranous glomerulonephritis patients achieved sustained remission with rituximab therapy. Other glomerular pathology included focal segmental glomerulosclerosis (n=1) and minimal change disease (n=1). Evidence of thrombotic microangiopathy was common (in isolation or combined with other pathology), as was acute tubular necrosis and tubulointerstitial nephritis. Of 14 patients with follow-up (2-64 months, mean 19 months), 6 had chronic renal insufficiency (serum creatinine >1.5 mg/dl), 2 had end stage renal disease, and 6 had essentially normal renal function. Our retrospective study shows that renal dysfunction in hematopoietic cell transplant recipients is often multifactorial, and biopsy may reveal treatable causes. Membranous glomerulonephritis is seen in autologous and allogeneic hematopoietic cell transplant recipients, and may respond to anti-B-cell therapy, which has implications regarding pathogenesis and relationship to graft-versus-host disease.

We report a patient with unknown primary undifferentiated carcinoma who developed acute renal failure associated with interstitial fibrosis following pemetrexed therapy. Despite drug withdrawal, renal function remained altered and the patient experienced chronic renal insufficiency. Pemetrexed disodium (Alimta) is a multitargeted antifolate agent approved by the Food and Drug Administration (FDA) for patients diagnosed with mesothelioma and non-small cell lung cancer. This drug is almost exclusively cleared by renal excretion [1]. The most common side effects are hematologic dose-limiting toxicities and nonhematologic toxicities including fatigue, diarrhea, nausea, mucositis and rash. Although few cases of renal failure have been published, no study has reported on the renal pathological findings in this setting. We present a case of acute tubular necrosis associated with interstitial fibrosis after pemetrexed therapy.
