Sweat sodium is not sweat chloride

Enzymatic measurement of sweat sodium and chloride.

treatment by HD show a significantly high ammonia concentration in arterial blood, but not in venous blood. Muscle detoxification may contribute to limiting the rise of ammonia in this condition. contribution of various organs to ammonia formation: a review of factors determining the arterial ammonia concentration. of blood ammonia alterations in uraemic patients under hemodialysis and CAPD.

Sweat rates, sweat sodium concentrations, and sodium losses in 3 groups of professional football players.

CONTEXT Sweat sodium losses have never been reported in a large cohort of American football players. OBJECTIVE To compare sweat rates (SwtRs), sweat sodium concentrations (SwtNa(+)), and sodium losses in 3 groups of players (backs and receivers [BK], linebackers and quarterbacks [LB/QB], and linemen [LM]) to determine if positional differences and, therefore, size differences exist. DESIGN ...

Sweat chloride is not a useful marker of clinical response to Ivacaftor.

Clinical trials have revealed that Ivacaftor significantly reduces sweat chloride in patients with cystic fibrosis who carry the G551D mutation. This finding has been incorporated into the commissioning guidelines in the UK with a sweat chloride reduction of 30% or below 60 mmol/L, specified as the main criteria for continued funding of Ivacaftor for individual patients. In a cohort of 24 adult...

The correlation between age and sweat chloride levels in sweat tests.

Protracted neonatal hypertrypsinogenaemia, normal sweat chloride, and cystic fibrosis.

The cystic fibrosis (CF) clinical spectrum has greatly expanded in the past few years, including atypical forms with low sweat chloride concentrations. Two cases are presented which suggest that children detected by neonatal CF screening whose trypsinogen concentrations are still raised by the second month of age could, despite a negative sweat test, be affected by an atypical CF with fully exp...
