OBJECTIVES Recent investigations have demonstrated that the classic hypochloremic, hypokalemic, metabolic alkalosis of hypertrophic pyloric stenosis (HPS) is not a common finding.Some have suggested a trend over time, but none has investigated factors contributing to laboratory derangement, such as duration of vomiting or patient age at presentation. We sought to determine the proportion of pat...

BACKGROUND and study objectives: Patients with end-stage cystic fibrosis (CF) develop respiratory failure and hypercapnia. In contrast to COPD patients, altered electrolyte transport and malnutrition in CF patients may predispose them to metabolic alkalosis and, therefore, may contribute to hypercapnia. The aim of this study was to determine the prevalence of metabolic alkalosis in adults with ...

Alkalosis and reduction of blood chlorides are known to occur in some cases of pyloric stenosis in infants (Hartmann and Smythe', Graham and Morris2, Maizels, McArthur and Payne3). The present investigation endeavours to determine how far such changes are characteristic of this malady. To this end, the chemical and clinical findings in consecutive cases occurring at the Infants' Hospital have b...

EDITORIAL SYNOPSIS Observations are described in an 8-year-old boy, the fifth case to be recognized of the syndrome previously known as 'congenital alkalosis with diarrhoea'. The condition appears to result from an abnormal handling of chloride ion in the alimentary tract; the pathognomic biochemical features are an invariably high faecal concentration of chloride and liquid stools which consis...

It is generally recognized that potassium deprivation may result in the development of a plasma alkalosis, which is characterized by the paradoxical excretion of an acid urine (1-12). Conversely, the administration of sufficient potassium chloride results in a plasma acidosis and the simultaneous excretion of an alkaline urine (8, 13-16). Studies previously reported have shown that the dichotom...

BACKGROUND The influence of common disturbances seen in preeclampsia, such as changes in strong ions and weak acids (particularly albumin) on acid-base status, has not been fully elucidated. The aims of this study were to provide a comprehensive acid-base analysis in severe preeclampsia and to identify potential new biological predictors of disease severity. METHODS Fifty women with severe pr...

The study was carried out on healthy Friesian calves (n = 10) aged between 10 and 30 days. Hypochloremia and alkalosis were induced by intravenous administration of furosemide and isotonic sodium bicarbonate. The venous and arterial blood samples were collected repeatedly. 2,3-diphosphoglycerate (2,3-DPG), hemoglobin and plasmatic chloride concentrations were determined. The red blood cell chlo...
