A case of secondary IgA nephropathy accompanied by psoriasis treated with secukinumab

Abstract

A 60-year-old man was diagnosed with psoriasis 4 years ago. Treatment with adalimumab (a monoclonal anti-TNF-α antibody) became ineffective 1 year ago, and proteinuria and urinary occult blood were detected. Treatment with topical medicine, ultraviolet therapy, and etretinate resulted in remission of psoriasis, and proteinuria and hematuria also improved. For maintenance of remission, treatment with secukinumab (a human anti-interleukin-17A monoclonal antibody) was initiated. After the induction phase, treatment was changed from once a week to once every 4 weeks. After 5 months, he developed nephritis with kidney dysfunction, hematuria, and severe proteinuria (14 g/g Cr) accompanied by pitting edema. After admission, treatment with secukinumab was continued. Kidney biopsy revealed IgA nephropathy with fibrocellular crescents, and immunofluorescence analysis did not detect galactose-deficient IgA1. With these findings, he was diagnosed as secondary IgA nephropathy associated with psoriasis. Tonsillectomy followed by steroid pulse therapy prevented proteinuria and kidney function. In this case, treatment of refractory psoriasis with secukinumab and tonsillectomy was effective, leading to remission of relapsing secondary IgA nephropathy. Therefore, secukinumab might play an immunological role in the treatment of nephropathy.



A case of posterior reversible encephalopathy syndrome in a patient undergoing automated peritoneal dialysis

Abstract

A 44-year-old man undergoing automated peritoneal dialysis (PD) developed headache and dizziness with truncal ataxia and ataxic gait. Severe hypertension (systolic blood pressure/diastolic pressure: 193/83 mm Hg) and lower extremity edema were present, and his PD efficiency (weekly KT/V: 1.49) was inadequate. Magnetic resonance imaging revealed diffuse hyperintensities in the brain stem and bilateral cerebellar hemispheres on fluid-attenuated inversion recovery and apparent diffusion coefficient mapping imaging. Based on these findings, the patient was diagnosed with posterior reversible encephalopathy syndrome due to hypertension and uremia. He was treated with antihypertensive agents, and we changed the PD prescription to improve PD efficiency. Thereafter, his symptoms gradually improved, and abnormal findings on brain magnetic resonance imaging disappeared in accordance with lowering blood pressure.



Oliguria due to extensive subcapsular hematoma in renal graft: does surgical intervention ensure better outcomes?

Abstract

A 58-year-old male patient, with end-stage renal disease secondary to hypertension, underwent living-related kidney transplant at our transplant unit. The transplant surgery went uneventful and brisk urine output was recorded. Four hours after the transplant, the output suddenly dropped despite normal central venous pressure. Doppler scan revealed an extensive peri-allograft hematoma and high renal arterial resistive indices (RI). The patient was taken to the operating room where capsulotomy of the subcapsular hematoma was done. Postoperatively, the urine output restored to normal and the patient was sent home on the 5th post-operative day with adequately functioning renal graft. Surgical capsulotomy seems to be a valid approach in the management of such cases.



Successful peritoneal dialysis for the end-stage kidney disease associated with Prader–Willi syndrome: a case report

Abstract

Prader–Willi Syndrome (PWS) is characterized by hyperphagia, severe obesity, and mental retardation from early childhood and occurs 1/10,000 to 1/15,000 live births in Japan. There is high prevalence of diabetes mellitus because of hyperphagia. The patient may sometimes face the necessity of renal replacement therapy (RRT) because of end-stage kidney disease (ESKD) caused by diabetes-associated kidney disease (DKD). Since mental retardation and extreme obesity usually prevent to introduce peritoneal dialysis (PD), hemodialysis (HD) has been the first choice of RRT. In this report, we experienced one case of patient with PWS suffering from ESKD due to DKD who started PD as an initial RRT and succeeded to continue for total of 40 months. The patient was 37-year-old man at the time of initiation of dialysis. PD was chosen for RRT because we suspected that he might have more technical difficulties for continuing HD. After several episodes of peritonitis, he successfully continues PD without peritonitis for next 27 months until the present time with good support by his family member. To our best knowledge, this is the first reported case of ESKD associated with PWS who was successfully treated with PD for long period.



A case of biopsy-proven oxaliplatin-induced acute tubulointerstitial nephritis with thrombocytopenia and anemia

Abstract

Oxaliplatin, a third-generation platinum agent, has been used for the treatment of colon, pancreatic, and stomach cancers in recent years. It carries a reduced risk of acute kidney injury (AKI) compared to the previous platinum agents, including cisplatin and carboplatin. Several cases of oxaliplatin-induced acute tubular necrosis (ATN) have been reported; however, only one case has been reported as acute tubulointerstitial nephritis (ATIN) histopathologically. Here, we present a case of biopsy-proven and dialysis-dependent ATIN, which dramatically resolved with steroid therapy. The patient was a 67-year-old male who had undergone chemotherapy for colon adenocarcinoma. He suddenly developed shaking chills, fever, and hot flashes at the end of the 18th 5-fluorouracil (5-FU)/l-leucovorin/oxaliplatin administration, and was admitted to our hospital. On the 4th day of hospitalization, severe renal dysfunction (creatinine 6.5 mg/dL) was observed. As oliguria continued, we initiated hemodialysis therapy on the 6th day of hospitalization. Drug-induced ATIN was strongly suspected due to the history of multiple exposures to oxaliplatin with allergic reaction and sterile pyuria. We began steroid therapy on the 8th day of hospitalization. Subsequently, renal biopsy was performed and the diagnosis of ATIN was made. The patient's renal function gradually improved, and 6 months later, it had returned to baseline. Our case demonstrates that we should consider not only ATN, but also ATIN, as potential presentations of oxaliplatin-induced AKI.



A case of acute kidney injury secondary to black cherry concentrate in a patient with chronic kidney disease secondary to type 2 diabetes mellitus

Abstract

There are many herbal products which are accessible to patients, and they may provide with many health benefits. Nevertheless, some of these supplements can lead to significant morbidity as they can also have important side effects and impact patient's organ systems. In this case report, we present a patient with chronic kidney disease secondary to type II diabetes mellitus who develops acute kidney injury and metabolic disturbances secondary to consuming black cherry concentrate as a mean to self-manage his gout flare. The most likely mechanism of injury was cyclooxygenase inhibition by anthocyanins, molecular compounds found in cherries that have a similar mechanism of action to nonsteroidal anti-inflammatory medications. Patient's kidney injury and metabolic disturbances improved after the discontinuation of black cherry concentrate. This is the second case report that presents a correlation between consumption of cherry concentrate in a patient with chronic kidney disease and acute kidney injury.



Chronological change of renal pathological findings in the proliferative glomerulonephritis with monoclonal IgG deposits considered to have recurred early after kidney transplantation

Abstract

Proliferative glomerulonephritis with monoclonal immunoglobulin G (IgG) deposits (PGNMID) is a rare disease that recently became recognized. Its pathological findings are characterized by the deposition of a single heavy chain subclass and a single light chain isotype. PGNMID has been proven to recur in renal allografts. Herein, the authors describe the case of a 46-year-old man who presented with nephrotic syndrome and progressive kidney injury following kidney transplantation. One month after transplantation, his clinical condition stabilized; however, the protocol biopsy showed depositions of IgG and complement on the glomeruli by immunofluorescence staining. Electron microscopy (EM) revealed granular electron-dense deposits (EDD) in the mesangium. Thereafter, renal biopsy was repeated because his proteinuria level increased. Proliferative glomerulonephritis, mainly in the mesangium, with IgG and complement deposits and mesangial and subendothelial EDD were observed; however, the pathological diagnosis was difficult. Renal dysfunction then became apparent, and renal biopsy was performed again 4 years and 10 months after kidney transplantation. Glomerular deposits on a single IgG subclass and a single light chain isotype (IgG3 kappa) with membranoproliferative features were observed. Abundant subendothelial EDD were detected on EM. Finally, the patient was diagnosed with PGNMID. Since it seemed that PGNMID had already developed at 1 month after transplantation, we considered recurrent PGNMID case in the allograft. The treatment for PGNMID has not been established yet, and even in this case, the graft function was eventually lost. For improving renal prognosis, early diagnosis and further investigation on the treatment are necessary.



Collapsing glomerulopathy in a child with LCHAD deficiency: a rare association

Abstract

Metabolic disorders, although rare, can involve multiple organ systems and have a varied presentation. Renal involvement has been reported in several metabolic disorders in the pediatric age group. We report a rare metabolic disorder, long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency, in a child who developed steroid-resistant nephrotic syndrome at the age of 5 years. Renal biopsy showed features of collapsing glomerulopathy. The child had progressive chronic kidney disease. Alternative immunosuppressants including tacrolimus failed to show any clinical improvement. There have been no reports of children with long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency developing steroid-resistant nephrotic syndrome and collapsing glomerulopathy. This case highlights the need to monitor renal function and proteinuria among this group of children.



Effectiveness of cryofiltration and mizoribine combination with oral steroid therapy in a patient with membranoproliferative glomerulonephritis due to essential cryoglobulinemia

Abstract

A 65-year-old male patient with nephrotic syndrome was admitted to our hospital due to worsening systemic edema and purpura on the limbs. He had an impaired renal function, low serum complement level, and elevated rheumatoid factor level. He was positive for cryoglobulin (monoclonal IgM-κ and polyclonal mixed-type IgG), and the results of his kidney biopsy showed a tissue profile of membranoproliferative glomerulonephritis (MPGN). Due to the fact that the secondary cause was unclear, he was diagnosed with MPGN due to essential mixed cryoglobulinemia. On hospital day 20, he was initiated on 50 mg/day prednisolone (PSL). On hospital day 43, oral mizoribine (MZR) at a dose of 150 mg/day was prescribed. On hospital day 49, cryofiltration was performed because the disease was steroid resistant. The treatment promptly decreased urine protein levels. Serum albumin and serum complement levels increased, and complete remission was achieved approximately three months after the initiation of treatment. The PSL and MZR doses were gradually reduced to 2 mg/day and 100 mg/day, respectively, without any reemergence of the symptoms of cryoglobulinemia or relapse of the nephrotic syndrome for three years. Here, we report this case with essential mixed cryoglobulinemia in whom we could achieve complete remission of the disease by adding cryofiltration to the oral corticosteroid and immunosuppressant therapy with mizoribine and could maintain for a long time.
