A case of a peritoneal dialysis patient with left pleuroperitoneal communication caused by a pericardial defect after coronary artery bypass surgery
AbstractA 74-year-old woman with reduced kidney and cardiac function and a history of coronary artery bypass surgery involving the gastroepiploic artery to the right coronary artery and posterior descending artery #4 presented with dyspnea on exertion. Shortly after the induction of peritoneal dialysis (PD), an increase in the left pleural effusion was observed, and a diagnosis of left pleuroperitoneal communication was made by puncture drainage. The pleuroperitoneal communication hole was not detected under thoracoscopic observation; however, a 10  mm-sized hole in the pericardium was found, confirming leakage of ICG-loa...

A case of hypertensive emergency with alveolar hemorrhage and thrombotic microangiopathy
AbstractA 28-year-old woman with a 5-year history of untreated hypertension was admitted for respiratory distress, hemoptysis, and retinopathy. Computed tomography showed diffuse plaques in both lung fields. Acute kidney injury, hemolytic anemia, and thrombocytopenia were noted. Kidney biopsy showed thrombosis with fibrinoid necrosis and edematous intimal thickening and luminal narrowing of the small renal artery, indicating thrombotic microangiopathy; the majority of glomeruli were collapsed. After 8  weeks of treatment with antihypertensive drugs, serum creatinine decreased to 1.0 mg/dL, and the patient recovered. In t...

Positive response of a hemodialysis patient with pure red cell aplasia on recombinant human erythropoietin therapy to cyclosporine and Roxadustat
AbstractRecombinant human erythropoietin (rHuEPO) is commonly used to treat anemia associated with chronic kidney disease (CKD). EPO-induced Pure Red Cell Aplasia (PRCA) is a rare condition of profound anemia with EPO treatment. Upon finding the development of EPO-induced PRCA, the treatment requires immediate withdrawal of EPO therapy and initiate new treatments with immunosuppression or renal transplantation. Anti-EPO antibody assay is not always positive in EPO-induced PRCA. Here, we report a case on the sudden development of PRCA in a hemodialysis patient receiving EPO and how we treated the condition successfully with...

Copper deficiency anemia due to zinc supplementation in a chronic hemodialysis patient
We report a case of a chronic dialysis patient with copper deficiency anemia caused by standard-dose zinc supplementation. The patient was a 70-year-old woman who had received maintenance hemodialysis for 8  years due to diabetic nephropathy. She had been treated with weekly administration of darbepoetin 30 μg for renal anemia, which resulted in Hb 12 to 14 g/dL. She had no dysgeusia. When zinc deficiency (44 μg/dL) had been identified 4 months earlier, 50 mg daily zinc acetate hydrate (Nobelzi n®), which is the standard dose, was started. Unexpectedly, her anemia progressed slowly with macrocytosis together with ...

De novo posttransplant membranous nephropathy after COVID-19 vaccination 9  years after renal transplantation in a patient with polycystic kidney disease
AbstractA 63-year-old man with polycystic kidney disease underwent kidney transplantation from his wife. Nine years later, after the first and second doses of the COVID-19 vaccination, he developed proteinuria, hematuria, and elevated C-reactive protein. Kidney biopsy 7  months after the initial appearance of proteinuria showed immunoglobulin (Ig)-G granular stain, predominantly IgG1, and spike formation in the glomerular basement membrane. Electron microscopy revealed mainly subepithelial deposits, which corresponds to membranous nephropathy (MN) stage 3 of the E hrenreich–Churg classification indicating chronic diseas...

Daratumumab therapy in a pediatric case of C3 nephritic factor-positive proliferative glomerulonephritis with monoclonal IgG deposits
We report the case of a 12-year-old male presenting initially with edema and hypertension who was subsequently diagnosed with IgG3/Kappa-dominant PGNMID. In the absence of any proven therapy and though without a detectable clone, he was empirically treated with daratumumab with positive effect to date. This is the first reported case of daratumumab monotherapy in pediatric PGNMID, as well as the first PGNMID case to detect presence of C3 nephritic factor. (Source: CEN Case Reports)

Transcatheter renal arterial embolization for intractable urinary fistula occurring after robot-assisted partial nephrectomy: a case report
AbstractPartial nephrectomy is the standard surgical procedure for small renal tumors. Since the advent of robot-assisted partial nephrectomy (RAPN), the number of cases of renal tumors undergoing the procedure has increased exponentially. Urinary fistula is a complication of partial nephrectomy. Conservative management using ureteral stents is useful in most cases of urinary fistulas. However, some patients develop intractable urinary fistulas. Herein, we report a case in which vascular embolization was useful for treating an infected and intractable urinary fistula that developed after RAPN. A 59-year-old man was acciden...

Additional renoprotective effect of the SGLT2 inhibitor dapagliflozin in a patient with ADPKD receiving tolvaptan treatment
AbstractAutosomal dominant polycystic kidney disease (ADPKD) is a major cause of end-stage kidney disease (ESKD). Vasopressin plays a pivotal role in ADPKD progression; therefore, the selective vasopressin V2 receptor antagonist tolvaptan is used as a key drug in the management of ADPKD. On the other hand, sodium –glucose cotransporter-2 inhibitors (SGLT2i), which may possibly stimulate vasopressin secretion due to the diuretic effect of the drug, have been shown to have both renal and cardioprotective effects in various populations, including those with non-diabetic chronic kidney disease. However, the ef fect of SGLT2i...

Two acute kidney injury episodes after ICI therapy: a case report
AbstractA 74-year-old Japanese male with lung squamous cell carcinoma received his first dose of immune checkpoint inhibitors (ICIs): ipilimumab and nivolumab. He developed acute kidney injury (AKI) and was admitted to our department. We diagnosed kidney immune-related adverse effects (irAE), and a kidney biopsy revealed acute tubulointerstitial nephritis. We started oral prednisolone (PSL) and his AKI immediately improved. The patient maintained stable findings after PSL was tapered off. However, seven months after the ICI administration, he developed rapid progressive glomerular nephritis and was admitted to our departme...

A case of seronegative microscopic polyangiitis following the diagnosis of renal pelvic carcinoma
AbstractThe incidence rate of malignancy in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is higher than that in the general population. Malignancy has been indicated to be a risk factor or inducer of AAV. Herein, we report the case of a healthy 84-year-old man with seronegative microscopic polyangiitis (MPA) after the  diagnosis of renal pelvic carcinoma. Four weeks before admission, his estimated glomerular filtration rate (eGFR) was 85 ml/min/1.73 m2, and no  hematuria or proteinuria was detected. Renal biopsy on admission revealed invasive urothelial carcinoma of the right ren...

A case of Duchenne muscular dystrophy recovered from prolonged ischemic kidney injury which emerged with a normal creatinine level
AbstractDuchenne muscular dystrophy (DMD) is an inherited disease characterized by progressive degeneration of the skeletal muscles. Renal dysfunction in patients with DMD has recently become more apparent as life expectancy has increased owing to advances in respiratory devices and heart failure therapies. A 23-year-old man with DMD who required nasal tube feeding was referred to our hospital with a 4-month history of renal dysfunction and anemia. The patient ’s serum creatinine (sCr) level was within the normal range (0.84 mg/dL), but his serum cystatin C level and estimated glomerular filtration rate calculated by cy...

Clostridium perfringens-induced massive hemolysis treatment with blood purification to target toxins: a case report
AbstractClostridium perfringens can rarely cause severe systemic infections, usually from an abdominal source, associated with massive hemolysis, which is usually fatal. Hemolytic anemia and acute renal injury resulting from toxin action are critical for the development of multiple organ dysfunction syndrome (MODs), making this condition a real emergency, requiring multispecialty skills and aggressive multimodal therapies. We herein describe a case of septic shock from acute cholecystitis with massive hemolysis caused byC. perfringens in a 55  year-old man that was successfully treated with early blood purification and co...

Lipoprotein glomerulopathy: a rare cause of steroid-resistant nephrotic syndrome in a child
AbstractLipoprotein glomerulopathy (LPG) is a rare condition of renal lipidosis characterized by lipoprotein thrombi in glomeruli, an abnormal plasma lipoprotein profile, and a marked increase in serum apolipoprotein E (apo E) levels. It is a monogenic disorder with autosomal dominant inheritance and the average age of presentation is 32  years (4–69 years). It is rare in children. The presentation can be nephrotic syndrome, hematuria, or progressive renal failure. Here we report the first described case of LPG in an Indian 7.5-year-old boy who presented with steroid-resistant nephrotic syndrome with normal renal funct...
