BACKGROUND/AIMS: Bile acids are synthesized in the liver and released into the intestinal tract to aid in digestion and absorption by increasing permeability via alteration of the cell membrane. Bedridden elderly patients typically have pressure ulcers that may be due to both physical local pressure as well as skin cell changes induced by the physiologic effects of bile acids. METHODOLOGY: This study investigated 31 elderly bedridden patients with pressure ulcers (mean age, 81.7 years) and 19 healthy elderly (mean age, 79.7 years). Five serum bile acid fractions were summed to determine total bile acid, and transaminase and cholesterol levels were also measured. RESULTS: Total cholesterol levels were significantly lower (p<0.05) in pressure ulcer patients and transaminase levels were not significantly different between the two groups. The primary bile acids were generally higher and the secondary and tertiary bile acids lower in pressure ulcer patients. In particular, the secondary bile acid deoxycholic acid was significantly higher in all pressure ulcer patients. When analyzed by grade of pressure ulcer, the primary bile acids were significantly lower in pressure ulcer patients. CONCLUSIONS: Secondary bile acid fraction deoxycholic acid measurements may indicate bedridden patients at higher risk for pressure ulcers. |
