OBJECTIVE: To assess the contribution of protein-losing enteropathy to AIDS-associated hypoalbuminemia.
DESIGN: Prospective assessment of patients with AIDS.
SETTING: An urban county hospital (Los Angeles & University of Southern California Medical Center. USA).
PATIENTS: Four groups of patients with AIDS were studied: (1) patients with normal serum albumin (> or = 3.9 g/dl) and normal bowel habits; (2) patients with normal serum albumin and diarrhea (> or = four loose or watery stools per day for > or = 2 weeks); (3) patients with hypoalbuminemia (< or = 3.0 g/dl) and normal bowel habits; and (4) patients with hypoalbuminemia and diarrhea.
MAIN OUTCOME MEASURE: Fecal alpha 1-antitrypsin concentration was used as a measure of protein loss in the gut.
RESULTS: Patients with hypoalbuminemia had a significantly higher mean fecal alpha 1-antitrypsin concentration than those with normal albumin (10.8 +/- 3.0 mg/g dry stool versus 2.4 +/- 0.4 mg/g dry stool; P < or = 0.001). Although mean fecal alpha 1-antitrypsin concentrations were similar in patients with and without diarrhea in the normal albumin group, patients with hypoalbuminemia and diarrhea had significantly higher levels of fecal alpha 1-antitrypsin than those with hypoalbuminemia and normal bowel habits (17.3 +/- 5.8 mg/g dry stool versus 4.6 +/- 1.0 mg/g dry stool; P = 0.009). Twelve out of 36 (33%) patients with normal albumin had elevation of fecal alpha 1-antitrypsin compared with 33 (70%) of 47 patients with hypoalbuminemia (P < or = 0.001). Linear regression analysis showed a significant negative correlation between serum albumin and fecal alpha 1-antitrypsin concentration (r = -0.38; P < or = 0.001). Fecal alpha 1-antitrypsin was significantly higher in patients with mucosal disease visualized at upper endoscopy or flexible sigmoidoscopy than in those without gross abnormalities (13.5 +/- 5.8 mg/g dry stool versus 2.4 +/- 0.7 mg/g dry stool; P = 0.005).
CONCLUSION: Protein-losing enteropathy is common in patients with AIDS and may contribute to the development of hypoalbuminemia in these patients.
