Faecal concentrations and output of short chain fatty acids (SCFA) were assessed on successive days by gas-liquid chromatography in 24 patients with acute watery diarrhoea. Absorption of water and sodium from the rectum was also measured by a dialysis technique in 17 of these patients and in nine normal subjects in the presence and absence of luminal SCFA. Faecal SCFA concentrations were low on the first day of diarrhoea (mean (SEM) 9.9 (5.8) mmol/kg) and increased to 94.8 (16.4) mmol/kg by the fifth day. Faecal output of SCFA corresponded to these figures. Net water absorption, in the absence of luminal SCFA, was stopped in patients with
acute diarrhoea
(-59 (81) nl/cm2/min) compared with healthy controls (+322 (63) nl/cm2/min) (p < 0.01).
Luminal
SCFA restored net water absorption to +184 (67) nl/cm2/min in patients with
acute diarrhoea
(p < 0.01). Net absorption of sodium decreased in patients with
acute diarrhoea
in the absence of luminal SCFA, but returned to normal with luminal SCFA. Net secretion of potassium increased in
acute diarrhoea
, and did not change in the presence of SCFA. Defective absorption from the rectum in
acute diarrhoea
is reversed by luminal SCFA. The reduction of luminal SCFA in
acute diarrhoea
treated conventionally may be a factor contributing to colonic dysfunction.
