Progression of immunoglobulin G4-related disease to systematic lupus erythematosus after gastric cancer surgery: A case report.

Rationale: Immunoglobulin G4 related disease (IgG4-RD) rarely coexists with other autoimmune diseases, though we had a patient whose primary clinical problem was shifted from IgG4-RD to systemic lupus erythematosus (SLE) after gastrectomy. The present paper aimed to report pathological findings and clinical course of the patient.

Patient Concerns: The patient was a male aged 74 years old with gastric cancer characterized by the following symptoms: Raynaud phenomenon, polyarthralgia, and swollen parotid glands on both sides.

Early recurrence of active IgA nephropathy after kidney transplantation.

IgA nephropathy (IgAN) is recurrent after transplantation; however, its time of recurrence is unpredictable. To date, factors influencing IgAN recurrence have not been elucidated. We present a case of a 23-year-old man with end-stage renal disease (ESRD) who underwent living-related ABO-identical pre-emptive kidney transplantation (PEKT) using his 57-year-old mother as a donor.

A case of recurrent light chain deposition disease after living-related renal transplantation - detailed process of the recurrence.

A 53-yr-old woman with end-stage renal disease was admitted for renal transplantation (RTX). About a decade ago, she had presented with urinary abnormalities. Monoclonal IgA lambda was detected.

A recurrent fibronectin glomerulopathy in a renal transplant patient: a case report.

Fibronectin glomerulopathy (FNG) is a rare, autosomal dominant renal disease with massive mesangial, and subendothelial fibronectin deposits. It presents proteinuria, often in the nephrotic range in the third to fourth decade, and slow progression to end-stage renal disease. The risk of recurrent disease in renal allograft is uncertain.

Is arteriolar vacuolization a predictor of calcineurin inhibitor nephrotoxicity?

Calcineurin inhibitors (CNI) have been commonly used as pivotal immunosuppressive agents to renal transplant recipients and have contributed significantly to improving short-term allograft survival. However, long-term administration of CNI may cause an adverse effect on kidney function, known as chronic nephrotoxicity. Chronic CNI nephrotoxicity (CNI-NT) shows characteristic histopathological findings that involve arteriolar hyalinosis.

Is the volume of the parathyroid gland a predictor of Maxacalcitol response in advanced secondary hyperparathyroidism?

We evaluated the relationship between the volume of parathyroid glands estimated by ultrasonography (US) and response of 22-oxa calcitriol (Maxacalcitol, OCT) in patients with secondary hyperparathyroidism (2HPT) to evaluate whether the volume can be a predictor of the OCT response. Eleven institutes participated in this study. Ninety-four patients with advanced 2HPT were enrolled.
