Diabetic nephropathy is the most frequent cause of chronic renal failure. The onset of microalbuminuria in patients with diabetes mellitus, which seems to be related to blood pressure and the control of glycemia, is predictive of the development of true proteinuria. This multicenter, single-blind, randomized study examined the effects of benazepril and nicardipine on overnight microalbuminuria in 57 normotensive and 46 hypertensive diabetic patients.

Thirty-six patients with essential hypertension with sitting diastolic blood pressures of 96-104 mmHg without (EH, n = 12) or with other risk factors (EH+S, n = 12, EH+DM, n = 12) were enrolled. After a 4-week, single-blind, placebo run-in period, the subjects received I-SRO 5 mg once daily for 18 weeks.

Many patients with arterial hypertension have abnormal urinary excretion levels of albumin. This study was aimed at examining the effects of lisinopril and amlodipine on urinary excretion of albumin and kidney function. Thirty-six previously untreated patients with essential arterial hypertension were divided randomly into two groups.

In a double-blind and random study 24 patients were treated with Nicardipine Retard (40 mg twice a day) whereas a further 12 received placebo twice a day.

A significant reduction of arterial blood pressure was seen after both treatment regimens. Circulating plasma glucose, insulin, C-peptide and triglyceride concentrations were measured at hourly intervals from 8.

Free and total CBZ levels tended to increase with increasing age, while CBZ-E levels did not show any significant age dependency. As a result, CBZ-E/CBZ ratios were higher in infants and preschool children than in the older age group.

A significant inverse correlation was found between the free fraction of both compounds and serum AAG, even though changes in AAG concentration explained only part of the variation in binding. No correlation was found between the free fraction of CBZ and CBZ-E and HSA, probably due to the small intersubject variation in HSA concentration.

A 4-year-old patient with generalized tonic-clonic seizures was started on CBZ after various ineffective therapies. On the 10th day of CBZ therapy, he was readmitted to the hospital because of reappearance of fits, and went into hepatic coma.

All three patients underwent a nocturnal polygraphic recording including continuous monitoring of systemic arterial pressure and heart rate. Two subjects showed increases and irregularities of arterial pressure before awakening with headache.

Isoelectric focusing of CSF and serum IgG followed by crossed immuno isoelectric focusing and direct immunofixation as well as quantitative assay of IgG and albumin were performed in 64 clinically definite multiple sclerosis patients. Intrathecal IgG synthesis was calculated according to the CSF IgG index and de novo CNS IgGsyn. Isoelectric focusing showed abnormal IgG fractions i CSF indicating increased intrathecal synthesis of oligoclonal IgG in 99% of patients.
