A 9-year-old boy was admitted with the diagnosis of myelodysplastic syndrome (FAB RAEB in T). The patient was treated with busulfan and cyclophosphamide and transplanted with bone marrow cells from an HLA identical sister. Cyclosporin A (CyA) and short term methotrexate (MTX) was given for prophylaxis against graft versus host disease (GvHD). The serum potassium value was observed to increase to 6.3 mEq/l during the period of CyA therapy. The serum potassium value returned to 4 mEq/l when CyA treatment was decreased to a serum concentration of less than 50 ng/ml (FPIA). On day 90 post transplantation the patient was diagnosed as relapsed. The patient was preconditioned with cyclophosphamide and total body irradiation and a second bone marrow transplantation was performed using cells from the same donor. He was treated again with CyA and short term MTX for the prevention of GvHD. Once again the patient became hyperkalemic with 6.8 mEq/l. The serum creatinine level was 0.9 mg/dl, the GFR was 52.1 ml/min, FEK was 7.1%. Pseudohypoaldosteronism or hyporeninemic hypoaldosteronism was suspected. To investigate this possibility a renin/aldosterone stimulation test was performed. We speculate that an idiosyncratic response to CyA resulted in pseudohypoaldosteronism and produced a defect in potassium secretion.

Ocular graft-versus-host disease (GVHD) occurs in more than one-half of patients who develop chronic GVHD after allogeneic hematopoietic cell transplantation (HCT), causing prolonged morbidity that affects activities of daily living and quality of life. Here we provide an expert review of ocular GVHD in a collaboration between transplantation physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. Recent updates in ocular GVHD regarding pathophysiology, preclinical models, risk factors, prevention, screening, diagnosis, response criteria, evaluation measures, and treatment are discussed. Ocular GVHD involves at least 3 biological processes: lacrimal gland dysfunction, meibomian gland dysfunction, and corneoconjunctival inflammation. Preclinical models have identified several novel pathogenic mechanisms, including the renin angiotensin system and endoplasmic reticulum stress signaling, which can be targeted by therapeutic agents. Numerous studies have identified reliable tests for establishing diagnosis and response assessment of ocular GVHD. The efficacy of systemic and topical treatment for ocular GVHD is summarized. It is important that all health professionals caring for HCT recipients have adequate knowledge of ocular GVHD to provide optimal care.
