Two Cases of Pneumocystis Carinii Pneumonia in Renal Allograft Recipients / 대한신장학회잡지

Renal allograft recipients are at risk for Pneumocystis carinii pneumonia (PCP) within the first year following transplantation and during treatment for graft rejection. We experienced two cases of PCP in renal allograft recipients. The first case was a 39-year-old female who had received renal allograft 7 years before. At the time of traosplantation, she was a carrier of hepatitis B surface (HBs) antigen. After transplantation, she had been received the rnaintenance dose of cyclosporine and oral prednisolone. Three months before adrnission, dosage of prednisolone was increased because of the increased serum creatinine level and gene-ralized edema. A week before admission, syrnptom of exertional dyspnea, dry cough, and fever was developed. Chest X-ray film showed streaky interstitial infiltration in both lung fields and chest CT showed diffuse ground-glass appearance. Rroncho- alveolar lavage revealed positive Grocott's methenamine silver stain for numerous clumps of pneumocystis carinii cysts. Despite the aggressive treatment, she died of respiratory and hepatic failure and GI bleeding. Another case was a 40-year-old male who had received renal allograft S years before. He had been received maintenance immune suppressive therapy with cyclosporine and oral prednisolone. He was admitted for evaluation of hypertension and elevated serum creatinine level. After several days of admission, he complained fever, dry cough and dyspnea. X-ray film showed pneumonic infiltration and the bronchial brushing and washing fluid revealed the Pneumocystis carinii cysts that were stained by methenamine silver. He was treated with the full dose of trimethoprim-sulfamethoxazole and clindamycin. Sacrificing the renal allograft, he recovered from Pneumocystis carinii pneumonia.

A Case of Multiple Endocrine Neoplasia Type 1 / 대한내분비학회지

Multiple endocrine neoplasia type 1 (MEN 1) is the association of neoplastic transformation of parathyroid, pituitary, and pancreatic islet cells. This syndrome is inherited as an autosomal dominant trait. A 38-year-old woman presented with general weakness and mental changes. She had experienced same symptoms 7 years ago, after then her weight gradually increased. Insulinoma was suspected by markedly decreased blood glucose level (20mg/dL) and the increased insulin/glucose ratio (0.43) that sampled in emergency room at the time of mental change. Unusually large pancreatic tail mass and Lt, adrenal gland mass were detected by abdominal CT. Percutaneous transhepatic portal vein catheterization with insulin sampling showed sudden step up of insulin/glucose ratio at the middle portion of pancreas. Measuring of basal pituitary hormones as a screening procedure of MEN showed increased basal prolactin level. Combined pituitary stimulation test showed blunted response of prolactin to TRH and sellar magnetic resonance imaging showed intrasellar mass. Thyroid nodule was palpated on her anterior neck. Thyroid scintigram showed cold nodule, and there was no lymphadenopathy around the nodule by the thyroid sonogram. Fine needle aspiration cytology showed benign hyperplastic follicular cells only. Serum ionized calcium and parathyroid hormone level were normal. Under the impression of MEN type I, the distal pancreatectomy, splenectomy, Lt. thyroid lobectomy and Lt. adrenalectomy was performed at the same time. Histologic examination of the surgically removed tissues revealed pancreas islet cell tumor, adrenal cortical adenoma and thyroid adenoma. Transient hyperglycemia was developed after surgical intervention, but thereafter she never felt any symptoms of hypoglycemia till now and her blood glucose showed completely normal level with oral glucose tolerance tests. We present this case with a review of literature.
