Subclinical adrenocortical insufficiency in renal amyloidosis.

In order to investigate the functional significance of possible adrenal amyloid infiltration in patients with renal amyloidosis, we performed corticotrophin stimulation tests in 15 patients having renal amyloidosis with no clinical evidence of adrenocortical insufficiency and 12 controls. In 7 of the patients, the cortisol increments obtained during the test were found to be consistent with primary adrenal insufficiency due to possible amyloid infiltration of the adrenal cortex; in contrast, in all control subjects, adrenal responses to the test were regarded as sufficient for proper adrenal function.

The expanding spectrum of a disease. Behçet's disease associated with amyloidosis.

In this report, we present a series of 6 patients with Behçet's disease (BD) associated with amyloidosis whose illnesses date back at least 4 years. In all the cases, nephrotic syndrome heralded the onset of amyloidosis, which was diagnosed by percutaneous kidney biopsies. After the diagnosis of amyloidosis, all subjects received colchicine, and steroids were discontinued. Three patients have benefited from treatment. It was suggested that amyloidosis may be an intrinsic feature of BD or that the suppurative lesions may play a role in the accumulation of amyloid in the tissues. The literature was reviewed and discussed.

Effects of nitrendipine on blood pressure and blood ciclosporin A level in patients with posttransplant hypertension.

In order to evaluate the antihypertensive effectiveness and interaction with ciclosporin A (CS-A) nitrendipine, a dihydropyridine derivative calcium entry blocking agent, was used in 16 (13 men, 3 women) hypertensive renal posttransplant patients followed by the Nephrology Department of Hacettepe University Hospital. The patients did not receive any antihypertensive drug for a 7-day period. They were then given 20 mg/day nitrendipine for 3 weeks. At the end of this period, mean (+/- SE) supine blood pressure fell from 163/108 +/- 3.6/1.87 to 141/87 +/- 3.8/2.2 mm Hg (p less than 0.01), while the heart rate was unchanged. 14 of 16 patients achieved full control of blood pressure levels with 20 mg/day nitrendipine, and only 2 patients needed a higher dosage of 30 mg/day (20 + 10 mg). After 3 weeks of treatment no significant variations in blood chemistry or renal functional parameters were noticed. There was also no difference between blood CS-A levels before and after treatment with nitrendipine (218.06 +/- 33 vs. 222.68 +/- 26 ng/ml, p greater than 0.05). We conclude that short-term therapy with nitrendipine in renal post-transplant patients does not appear to be harmful and longer term studies are needed to fully evaluate safety and efficacy of this drug. Because it influences neither blood chemistry nor renal functional parameters and blood CS-A level, it may be preferable to other calcium channel blocking agents in this group of patients.

Spontaneous perirenal haematoma secondary to polyarteritis nodosa.

Spontaneous perirenal haematoma (SPH) is an unusual but serious complication of polyarteritis nodosa (PAN). We present 3 patients with PAN-associated SPH. One was diagnosed pre-operatively and underwent emergency nephrectomy in order to stop the persistent bleeding; the second patient had surgical drainage of the haematoma and the third recovered without undergoing surgery. The diagnosis is discussed.

The effect of renal transplantation with a minimal steroid regime on uraemic hypertriglyceridaemia.

We have studied the lipid and associated biochemical indices in 18 renal transplant patients maintained on an alternate day prednisolone regime. At an average 27 months following transplantation serum lipids were not significantly different from normals despite some renal impairment in the transplant recipients. In addition the blood sugar and plasma immunoreactive insulin levels were elevated in transplanted patients. The intravenous fat tolerance test (IVFTT) was not found to be different from that of normals. In some patients IVFTT was performed before and after transplantation and it was shown that K2 (fractional removal rate of Intralipid) improved from abnormal to normal values. Thus, it has been demonstrated that previously abnormal lipid levels can return to normal after transplantation and this may be related to alternate day steroid regimes. Impaired removal of triglyceride seen in chronic renal failure is improved by transplantation.

Hypertension because of an arteriovenous fistula between the right renal artery and the inferior vena cava secondary to a gunshot wound: a case report.

A case of a renovascular hypertension due to an arteriovenous fistula between the right renal artery and the IVC secondary to a gunshot wound 8 years previously is reported. The diagnosis was made initially by the clinical signs of a continuous bruit heard over the anterior abdomen and by the characteristic findings of diastolic hypertension. Diagnosis was confirmed by abdominal aortography. In the operation, the right renal artery was ligated and divided proximally between the aorta and the aneurysm and distally beyond the fistulous communication and a Gore-Tex graft was anastomosed between distal part of the renal artery and abdominal aorta. The result was confirmed by postoperative aortography and by disappearance of the preoperative physical findings. The present case, to our knowledge, is the sixth in the literature.

Accelerated hypertriglyceridemia in patients on continuous ambulatory peritoneal dialysis - a preventable abnormality.

Increasing hypertriglyceridemia is a recognised complication of CAPD. To investigate the etiology lipid clearance studies using the intravenous fat tolerance test were performed in control subjects and in uremic patients before and after six months CAPD treatment. Oral carbohydrate intake was restricted and the use of hypertonic dialysate kept to a minimum. Although serum triglycerides were elevated in the uremic patients before CAPD (3.1 +/- 0.3 mMol/L) no further increase occurred during therapy. Oral carbohydrate intake was restricted to 240-250 Gms/24 hrs and hypertonic dialysate to 5.7 +/- 4.1% of the total. There were no significant changes in fractional removal rate of lipid. Therefore further increases in serum triglycerides in CAPD may be prevented by simple dietary manoeuvres.
