    Notes: Summary Renal function has been evaluated in 21 patients treated with cyclosporin A (CyA) for 9 months for idiopathic uveitis. Serum creatinine, which was 82 µmol·l−1 before treatment, was significantly elevated after 1 month (111 µmol·l−1). After 9 months of treatment, and despite a decrease in CyA dosage, the mean plasma creatinine remained elevated at 132 µmol·l−1. Hypertension developed in 6 patients, five of them being concomitantly treated with corticosteroids. In 8 patients serum creatinine 3 months after CyA had been stopped had decreased from 148 to 93 µmol·l−1. Two of those patients remained hypertensive 3 months after CyA treatment had ceased. In patients with idiopathic uveitis CyA induces a reversible increase in serum creatinine. However the reversibility of such a biochemical marker does not preclude a histopathological lesion. Chronic renal damage may be responsible for the persistance of hypertension after cessation of CyA treatment

    Notes: Summary Plasma atrial natriuretic peptide (ANP) concentrations were measured by radioimmunoassay 1 to 12 days after operation in six patients with artificial hearts. The mean levels were significantly higher in artificial heart recipients (58.2 pg · ml−1) than in controls (12.6 pg · ml−1). The mechanism underlying the raised values is not clear, although it is suggested that elevated atrial pressure may have been the stimulus for higher ANP release. In 3 patients plasma ANP concentrations were also measured 1 to 5 days after orthotopic transplantation. In all of them ANP concentrations had increased by 20 to 74% despite lower right atrial pressure. An increase in atrial tissue mass may have contributed to the raised plasma ANP after orthotopic transplantation. It also suggests that the functioning sympathetic nervous system is not a necessary condition for ANP release.

    Notes: Summary We have tested the effects of calcium channel blockade with diltiazem on methotrexate-induced nephrotoxicity in patients with biopsy-proven malignant disease. The patients were randomized in a cross-over fashion to receive MTX (4 g · m−2 body surface area) with or without Diltiazem (360 mg per day orally) during two consecutive periods separated by a 3-week interval. Methotrexate caused reversible acute renal failure, with an increase in serum creatinine from 89 (7)µmol·1−1 on day 0 to 150 (6)µmol.·1−1 on Day 6. The patterns of β2-microglobulin and N-acetyl glucosaminidase urinary excretion were similar, with a sharp increase from Day 0 to Day 3. Urinary β2-microglobulin excretion increased from 161 (57) µg·1−1 on Day 0 to 1160 (840) µg·l−1 on Day 3 and fell to 918 (530) µg·l−1 on Day 10. Urinary Nacetyl glucosaminidase excretion increased from 250 (100) mmol·h−1 per mg of creatinine on Day 0 up to 655 (261) on Day 3 and fell to 285 (82) on Day 10. The evolution of renal function was not influenced by diltiazem. In patients receiving diltiazem, serum creatinine increased from 93 (0) µmol·l−1 on Day 0 to 151 (68) µmol·l−1 on Day 6 (p = NS when compared with control values). Urinary enzyme excretion also markedly increased from Day 0 to Day 3 to the same extent as in the group not receiving diltiazem. Our data indicate that acute deterioration in renal function caused by methotrexate is accompanied by tubular damage. Diltiazem was ineffective in preventing the acute renal failure induced by methotrexate. An inadequate dosage of diltiazem or multifactorial toxic effects of methotrexate may account for this negative result.

    Notes: Abstract Appetite suppressants, including aminorex and fenfluramine, have been associated with pulmonary hypertension ever since the well-known outbreak of primary pulmonary hypertension in Europe after treatment with aminorex. The usage of a new anorectic agent, dexfenfluramine, has recently increased dramatically in developed countries. We report 2 new cases of lethal pulmonary hypertension associated with the use of dexfenfluramine.

    Notes: Abstract Erdheim-Chester disease is a rare, distinctive lipoidosis characterised by deposition of cholesterol-laden foam cells in the bone marrow associated with a granulomatous reaction affecting the lungs, pericardium, heart and retroperitoneum. A case of Erdheim-Chester disease is presented, with typical skeletal involvement (i. e. diffuse sclerosis of the diaphyses and metaphyses of the long tubular bones) and atypical features including thrombocythemia and renal involvement which was documented on computed tomography. Other features of the reported case include gonadttrophin insufficiency and diabetes insipidus.
