Clinical differentiation of fulminant Wilsonian hepatitis from other causes of hepatic failure.

Establishing a diagnosis of fulminant Wilson's disease can be difficult because Kayser-Fleischer rings may not be present and parameters of copper metabolism, including serum and urinary copper, and serum ceruloplasmin levels are neither specific nor diagnostic. In this study, ratios of both the serum alkaline phosphatase to total bilirubin and aspartate transaminase to alanine transaminase were constructed to evaluate their usefulness in differentiating fulminant hepatic failure caused by Wilson's disease (n = 6) from other etiologies (n = 43). An analysis of the data showed that cutoff values of less than 2.0 for the alkaline phosphatase-total bilirubin ratio and greater than 4.0 for the aspartate transaminase ratio were associated with a diagnosis of fulminant hepatic failure caused by Wilson's disease only (P less than 0.001). The alkaline phosphatase-total bilirubin ratio of less than 2.0 provided 100% sensitivity and specificity in identifying fulminant hepatic failure caused by Wilson's disease from other types of fulminant hepatic failure.

Liver transplantation. Initial experience in the Veterans Administration.

The Veterans Administration entered the clinical liver transplant field in 1983 and continued its program through July 1988. During this time interval, from the 172 Veterans Administration Medical Centers in the United States, 146 contact calls were initiated to the single center authorized to do liver transplants for the Veterans Administration. One hundred one (69%) of these contact calls resulted in a patient evaluation. Of the 101 patients evaluated, 77 (76%) were accepted for liver transplantation (OLTx). Of these 77, 67 (87%) were transplanted. The reasons for denial of transplant evaluation were numerous and included metastatic cancer, active alcoholism, homosexuality, and a variety of concurrent medical problems. The reasons for denying liver transplantation after evaluation were similar and included concurrent medical problems that contraindicated transplantation (N = 14), metastatic cancer (N = 6), and liver disease of insufficient severity to justify transplantation (N = 3). The number of transplants performed annually by the Veterans Administration increased from one in 1983 to 21 in 1988. Seventeen second grafts and two third grafts were transplanted in 17 cases, resulting in a retransplant rate of 22%; 46% of the patients receiving a second graft survived. None of those receiving three grafts survived. The reasons for retransplantation included acute and/or chronic rejection (N = 6), hepatic artery thrombosis (N = 5), primary graft failure (N = 4), recurrent cancer (N = 2), fulminant hepatitis and portal venous emboli (one each). A total of 45 transplanted patients are still alive (67% of those transplanted).(ABSTRACT TRUNCATED AT 250 WORDS)

Immediate plasma potassium levels in treating diabetic ketoacidosis.

A patient presented with diabetic ketoacidosis and severe hypokalemia (less than 2.0 mmol/L [less than 2.0 mEq/L]). The availability of immediate plasma potassium levels using a blood gas analyzer (Radiometer) prevented the use of potentially hazardous therapy. Potassium levels should be determined immediately using this technology in all patients with ketoacidosis.
