Serum levels of coenzyme Q10 (CoQ10) as well as lipids weredetermined in patients during total parenteral nutrition (TPN). The mean CoQ10 levels (M±SD) were 0.77±0.30μg/ml for 108 normal subjects and ...0.59±0.35μg/ml for 95 patients before TPN. The mean CoQ10 level of the patients decreased significantly to 0.35±0.23μg/ml one week after the start of TPN, and then remained almost unchanged during TPN for up to 6 weeks. When the patients receiving TPN (TPN patients) were grouped according to their clinical diagnoses, the mean CoQ10 level of patients with cancer was significantly lower than that of the other patients without cancer in 4 week therapy, but there was no difference in the levels between the patients with and without diseases of the gastrointestinal tract. Serum levels of total cholesterol (T-Chol) and esterified cholesterol in TPN patients also declined below their respective normal ranges, but not to the same extent in comparison to CoQ10. The levels of triglycerides (TG), phospholipids (PL), non-esterified fatty acids, low density lipoproteins, very low density lipoproteins, chylomicrons, and cholesterol in the high density lipoprotein fraction in serum of TPN patients were within their normal ranges. The levels of CoQ10 in TPN patients were correlative to those of T-Chol, TG, and PL, and decreased rapidly prior to the latter levels.
Nutritional status was assessed in 214 CAPD patients from eight centers in Japan. All patients were receiving adequate dialysis, as indicated by KT/Vurea and Karnofsky's activity scale. Subjective ...global assessment indicated that 25% of 83 female patients and 27% of 131 male patients were, at least, moderately malnourished. Mid-arm muscle circumference was lower in malnourished male patients than in well-nourished patients, however, in female patients none of the anthropometric variables reflected nutritional status. Lower serum albumin level was observed in lnourished male patients, but not in female patients. Daily protein intake, estimated from protein catabolic rate (PCR) was approximarely 0.8g/Kg BW in both males and females. This value is similar to those reported in literatures for CAPD patients. In our well-rehabilitated patients, PCR did not reflect the nutritional status as indicated by subjective global assessment. The data suggest that low protein intake was not always the major cause of malnutrition in these patients and that other factors, such as endocrine disorder, may also have contributed to malnutrition.
