Changes in urinary enzyme levels following the use of antihypertensive agents in patients with essential hypertension.

When choosing antihypertensive agents for the treatment of hypertension, it is necessary to consider the predisposition of individuals to renal damage, which may be associated with the long-term effect of such agents. In this respect, this study examined the effect of two commonly used antihypertensive drugs (Brinerdin and Minizide) on renal function over 24 months in patients diagnosed as having essential hypertension. We utilized urinary enzyme studies, which are indicators of subtle renal dysfunction. Other parameters of glomerular and tubular function were also determined in the pretreatment period, as well as during and at the end of treatment of 28 patients (16 males and 12 females) with therapeutic doses of Brinerdin and 22 patients (12 males and 10 females) with conventional doses of Minizide. During the follow-up period, blood pressure (BP) fell from a mean of 160/108 +/- 9/4 (SD) mmHg to 130/90 +/- 7/4 on Brinerdin and from a mean of 160/106 +/- 5/2 (SD) mmHg to 130/90 +/- 8/5 on Minizide. There was no significant difference in the levels of BP between the patients taking Minizide and those taking Brinerdin before, during, and at the end of treatment. Significant elevation (p < 0.05) of the levels of urinary protein, lactate dehydrogenase (LDH), and N-acetyl-B-D-glycosaminidase (NAG) was observed in patients on Minizide during treatment, and these levels remained elevated during the latter part of the study. Normotensive, untreated, age- and sex-matched control subjects showed no such urinary parameter changes.(ABSTRACT TRUNCATED AT 250 WORDS)

Influence of atypical neuroleptics on executive functioning in patients with schizophrenia: a randomized, double-blind comparison of olanzapine vs. clozapine.

Accepted clinical evidence suggests superior efficacy of novel antipsychotics in the treatment of cognitive symptoms in schizophrenia. Whether this constitutes a primary drug effect or a secondary effect due to easing extrapyramidal side-effects or improving positive symptoms when converting from a first- to a second-generation neuroleptic is still open to debate. Long-term efficacy as well as differential drug effects on cognitive performance are also poorly documented. We therefore compared cognitive performance of olanzapine vs. clozapine treatment in a controlled, randomized, double-blind trial. Fifty-four patients were assessed following a 2- to 9-day washout and again after 4 and 26 wk of neuroleptic treatment. Patients were rated on the PANSS for psychopathological changes, extrapyramidal side-effects were assessed on the Simpson-Angus Scale, and cognitive performance was assessed with the Stroop, Wisconsin Card Sorting and the Tower of London tests. Schizophrenia symptoms, extrapyramidal side-effects and cognitive performance improved significantly in the course of either drug treatment. Stroop test performance and Tower of London planning time improved significantly over 26 wk compared to baseline and 4-wk follow-up assessment while Wisconsin Card Sorting and Tower of London execution time improved significantly after 4 wk with no further improvement after 26 wk. Improved executive function was not related to improving positive symptoms and easing extrapyramidal side-effects, thus indicative of a primary treatment effect of either antipsychotic. However, Stroop reaction time improved with olanzapine while clozapine had a stronger effect on improving negative symptoms, thus suggestive of a differential drug effect.

Hypokalemic myopathy during treatment with diuretics.

Two male patients with severe reversible muscle weakness and excessive potassium deficiency associated with alkalosis during treatment with diuretics are presented. The case reports are further illustrated by the morphologic changes as seen in light and electron microscopic examination of muscle biopsies. Hypokalemia and muscle dysfunction are discussed in relation to other investigations of altered potassium metabolism and myopathy during treatment with certain diuretics.

Clinical evaluation of Brinaldix. A new oral diuretic.

'Brinaldix', a new non-thiazide oral diuretic, has been used in a trial on three normal subjects and fourteen patients with oedema from various causes. It is a potent salidiuretic and proved superior to bendrofluazide in 10 out of 14 patients. It produced a substantial potassium diuresis, and we are of the opinion that potassium supplements should be given in conjunction with it. In one normal subject it produced a period of postural hypotension; no other major side-effects were noted.
