This single center analysis shows further improvement in the already excellent long-term, cadaveric renal allograft survival with Aza since the introduction of CsA. In contrast to the findings from the UCLA/UNOS multicenter registries, these results support other observations that the type of maintenance immunosuppression does indeed influence the long-term attrition rate of cadaveric, renal allografts.
This paper describes an expert system for the interpretation of acid-base disorders. The target users are residents in training in internal medicine, anaesthesia and intensive care medicine. The program is written in PROLOG and runs on a SUN 3/160 minicomputer. Evaluation of a learning set (N = 202) and a test set (N = 194) has proved that the system's accuracy is acceptable. As a result, the program has recently been put in routine clinical practice.
Four consecutive patients with alcoholic cirrhosis and hepatorenal syndrome were treated with misoprostol, a synthetic methylester prostaglandin E1 analogue at twice the dosage advocated for anti-ulcer therapy (i.e., 0.4 mg four times per day orally) and albumin infusions. The mean urinary output obtained over the 3 days preceding misoprostol administration was 250, 315, 550 and 195 ml per 24 h, respectively, in the four patients, despite adequate volume expansion by plasma albumin to reach normal or high central venous pressure. Diuresis increased to 1450, 2440, 925 and 1300 ml, respectively, on days 2-4 after onset of therapy. Serum creatinine levels were 71, 51, 33 and 35 mg/l before and dropped to 26, 21, 13 and 17 mg/l during treatment. All patients had hyponatraemia (117-128 mequiv/l) which normalized, although they were continued on a low sodium intake of less than 10 mequiv per 24 h. Urinary sodium excretion increased from 0.4-3 mmol per 24 h, to 15-40 in the first two cases and only slightly to 3-5 in the last two patients. Three patients died after 10, 30 and 40 days due to oesophageal bleeding, encephalopathy or pulmonary infection, whereas one patient underwent an orthotopic liver transplantation when her serum creatinine attained a level of 13 mg/l. In the first patient, hepatorenal syndrome recurred 10 days after stopping the misoprostol treatment. High doses of misoprostol in the presence of adequate volume expansion thus seem to produce marked diuresis and creatininuria as well as mild natriuresis.(ABSTRACT TRUNCATED AT 250 WORDS)
Acute abdominal complications of systemic lupus erythematodes requiring laparatomy are not frequent. A 30-year-old man with systemic lupus erythematodes developed a necrotizing enteritis of the small bowel with pneumatosis intestinalis. Only one case of intestinal vasculitis associated with systemic lupus erythematodes has previously been reported. Presence of intramural gas in the small bowel and of gas in the portal vein was detected on plain abdominal film and confirmed by subsequent CT examination. Since corticosteroids often mask the severity of the disease, radiological evaluation is essential to the overall management of the patient with intestinal vasculitis. Due to the observed radiological signs, emergency laparotomy was performed. Histologic examination revealed necrotizing enteritis due to vasculitis.

A review is given of recent data on the role of cyclo-oxygenase products in mediating glomerular hyperfiltration in renal disease and on the role of prostaglandins in protein-induced glomerular hyperfiltration. The possible beneficial effects of cyclo-oxygenase inhibitors and thromboxane synthetase inhibitors are discussed.

A rare case of butylglycol intoxication in a suicide attempt is reported. Coma and hypotension were present on admission and severe metabolic acidosis arose subsequently. Forced diuresis and haemodialysis led to an uneventful outcome.
Recombinant-human erythropoietin (r-HuEPO) was administered to 24 anaemic pre-dialysis patients with end-stage renal disease. R-HuEPO was injected i.v. three times weekly during the first two months (correction phase). Fixed dosages of 50 U/kg, 100 U/kg, and 150 U/kg were used, and each dose group consisted of eight patients. During the subsequent six months r-HuEPO was given once weekly and the dose was adjusted to maintain a stable haemoglobin value (maintenance phase). The mean +/- SD haemoglobin increased from 9.3 +/- 0.6 to 11.1 +/- 1.3 g/dl with 50 U/kg, from 7.9 +/- 1.4 to 11.8 +/- 1.7 g/dl with 100 U/kg and from 8.4 +/- 1.0 to 12.1 +/- 1.1 g/dl with 150 U/kg of r-HuEPO. The two highest dose groups showed a marked reticulocytosis and a transient thrombocytosis. During the maintenance phase haemoglobin remained stable (11.9 +/- 1.1 g/dl) at a mean dose of 199 +/- 139 U/kg of r-HuEPO per week. Blood pressure did not increase, but in nine of eighteen previously hypertensive patients antihypertensive medication was increased. One hypertensive patient developed seizures. No accelerated progression of renal failure could be demonstrated. All patients reported an improved sense of well-being. R-HuEPO is an important new therapeutic agent for the treatment of anaemia of end-stage renal failure that is also effective in pre-dialysis patients.
A total of 20 renal transplant patients with end-stage diabetic nephropathy entered a randomized controlled trial comparing preoperative, fractionated total lymphoid irradiation (TLI) (radiation dose, 20-30 Gy) with postoperative cyclosporin A (CsA). Both groups received postoperative low-dose methylprednisolone maintenance therapy. The 3-year patient and graft survival was similar for both groups (100% and 71% in the TLI and 75% and 75% in the CsA group, respectively). Rejection crises occurred significantly more frequently (P less than 0.01) in the TLI-treated recipients. The incidence of infectious or diabetic complications was not significantly different in both groups. It is concluded that TLI and CsA are both effective treatment modalities for cadaveric renal transplantation in diabetics; CsA, however, is superior in preventing rejection crises.
