[The ACE inhibitor spirapril in chronic renal failure, hypertension and diabetic nephropathy].

The evidence from recent clinical outcome trials in arterial hypertension (AH) and the treatment guidelines from national and international authorities have placed a clear emphasis on "tight" blood pressure (BP) control. This has been particularly well illustrated in the treatment of patients with diabetes mellitus and AH where "tight" BP control clearly improves the outcome with reduced numbers of fatal and non-fatal cardiovascular events. Whilst the clinical trials in AH have identified benefits through BP reduction with a range of antihypertensive drugs there is a considerable volume of evidence to suggest that the optimal treatment for diabetic nephropathy and microalbuminuria should be based upon ACE inhibition. It is widely held that inhibition of intra-renal renin angiotensin systems leads to greater benefit than can be achieved by hemodynamic changes alone. Thus, management of AH and nephropathy in both DM and other forms of renal disease revolves around BP reduction through an ACE inhibitor-based treatment regimen. Where there is renal failure it may be prudent to administer a drug such as spirapril which has non-renal elimination mechanisms and which has been shown to have no accumulation problems or increased adverse effects.

Hypercalcaemic osteomalacia due to aluminium toxicity.

In 16 patients with chronic renal failure and osteomalacia resistant to vitamin-D therapy, aluminium was demonstrated in bone biopsy specimens at the interface between thickened osteoid and calcified bone by means of both X-ray microanalysis and a specific histochemical stain. 14 patients also had hypercalcemia. It is suggested that this is due to the blocking by aluminium of additional calcium uptake into bone coupled with the availability of additional calcium from dialysis fluid and vitamin-D therapy. This study provides more aetiological evidence linking aluminium and the development of osteomalacia in chronic renal failure. Further, if hypercalcaemia develops in such patients it is important that aluminium toxicity be excluded as the cause to prevent unnecessary parathyroidectomy.

The effect of residual insulin secretion on exocrine pancreatic function in juvenile-onset diabetes mellitus.

Residual beta cell function was studied in 18 juvenile-onset diabetics by measuring serum C-peptide immunoreactivity (CPR) fasting, and after IV injection of glucagon (1 mg). This was compared with the exocrine pancreatic response to an IV infusion of secretin and cholecystokinin-pancreozymin. Outputs of pancreatic bicarbonate, amylase and trypsin were measured. Exocrine secretory pancreatic function was decreased in 14 patients. Fasting and maximal CPR showed that 9 patients had residual insulin secretion. For these 'CPR-secretors' there was a strong correlation between CPR and output of bicarbonate (r = 0.87, p less than 0.005) and amylase (r = 0.7, p less than 0.05), but not with trypsin. These results suggest the existence of an endocrine-exocrine relationship in the pancreas.
