Variable Pulmonary Manifestations in Hemodialysis Patients

A wide variety of pulmonary disorders related to hemodialysis or pre-existing renal disease occurs in hemodialysis patients. The disorders may be classified as 1) pulmonary abnormalities associated with chronic renal failures; 2) pulmonary complications arising during hemodialysis; 3) pulmonary infection; or 4) pulmonary-renal syndrome. An awareness of the various possible pulmonary disorders arising in hemodialysis patients may be helpful for the proper and timely management of such patients. We describe and illustrate various radiographic and CT findings of variable pulmonary disorders in hemodialysis patients.

A Case of Drug-Induced Acute Interstitial Nephritis Accompanying Prominent Neutrophil Infiltration / 대한내과학회지

Drug-induced acute interstitial nephritis, induced by unknown immunologic mechanisms, is inflammatory lesions of the tubulointerstitial area due to several kinds of drugs as hapten and a rare, but increasingly recognized cause of acute renal failure. Drugs implicated include not only methicillin and other penicillins but also diuretics and nonsteroidal anti-imflammatory agents. Diagnosis of acute interstitial nephritis is important, because withdrawal of the offending agent will usually result in rapid improvement in renal function, and steroid therapy may reduce residual chronic renal damage. We are reporting a case of diuretic-induced acute interstitial nephritis in a 49 year-old female patient, who was given hydrochlorothiazide to treat hypertension. A percutaneous biopsy showed tubulointerstitial nephritis accopanying prominent neutrophil infiltration without glomerulitis. Withdrawal of the drug and use of corticosteroid led to remarkable improvement with renal function returning to normal.
