Albumin loss in the dialysate was evaluated during a total of 5 peritoneal dialyses carried out on 3 uraemic patients. The measurements were made by two different methods, the first based on the evaluation in the dialysate of intravenously injected radioiodinated albumin, the second one based on a radioimmunoassay of the protein in the dialysate. The results obtained showed three main mechanisms of protein loss during peritoneal dialysis: 1) albumin shift from extravascular sites adjacent to the peritoneum, 2) direct passage of albumin from blood stream to peritoneal cavity, and 3) tendency of the inter-dialysis peritoneal fluid to equilibrate with plasma proteins. Furthermore, the observations made on a patient with evident peritonitis proved the importance of the intrinsic biological properties of the peritoneum in determining the amplitude of protein wasting by the dialysate.

Total protein concentration, zinc, prealbumin, albumin, alpha-1-, alpha-2-, beta- and gammaglobulin concentrations were measured in serum samples collected in three successive years (1982, 1983 and 1984) from children (1 month-15 years) of Kikwawila village, Tanzania. The analysis of a total of 1590 serum samples provided the baseline data for children living in a rural Tanzanian community. The total protein values and the concentrations of betaglobulin were within the range described for Caucasians. Albumin, prealbumin, alpha-1- and alpha-2-globulin concentrations were below these standard values. On the other hand the gammaglobulin concentration was twice as high. The concentrations of total protein, gammaglobulin and prealbumin correlated with age. From 1982 to 1983 a significant decrease of most of the serum components (incl. zinc) was observed, although in children older than 2 years the alpha-1-globulins increased. All values increased again from 1983 to 1984, except for the zinc concentration, which decreased further. The individual fluctuations were analysed by comparing paired values for the children participating in the period 1982-1983, or 1983-1984. The proportion of children showing large fluctuations, sometimes exceeding the selected limits of tolerance, was larger in the period 1982-1983 than 1983-1984. This was consistent with the overall pattern found for all children. The prealbumin level, which has been postulated to be an indicator for malnutrition or borderline malnutrition, was analysed in detail. The values were far below normal values (200-300 mg/l), reaching a plateau with 130 mg/l among 4-6-year-old children. The individual fluctuations indicated a decrease from 1982 to 1983, which was considerable both in terms of the proportion of children showing a decrease (55%) and in the magnitude of the decrease. There was an increase from 1983 to 1984 but this increase did not compensate for the loss in 1983. Prealbumin concentrations showed a slight trend towards decreased values with stunting and wasting. No direct correlation was found between the other biochemical parameters and the parasite or anthropometric data collected at the same time. It was difficult to establish direct relationships between the biochemical parameters, which mainly indicate the health status of the child at the time-point of the survey, and anthropometric parameters which reflect the history of the individual over a long period. No direct correlation could be established between the biochemical parameters and the parasitological data.(ABSTRACT TRUNCATED AT 400 WORDS)

The loss of body cell mass (bcm) in senescence and wasting is poorly understood. We now show that the plasma cystine/acid soluble thiol ratio, ie, an indicator of the redox state, is increased in old age and cancer patients and correlated with a decrease in bcm and plasma albumin. A cause/effect relationship was suggested by two independent studies with N-acetyl-cysteine (NAC). NAC caused an increase in the bcm of healthy persons with high plasma cystine/thiol ratios, and treatment of cancer patients with NAC plus interleukin-2 caused an increase in bcm, plasma albumin, and functional capacity. Albumin levels below 680 micromol/L were associated with an increase in body water. Our studies suggest that the shift in the redox state may contribute to the loss of bcm and may provide a quantitative guideline for therapeutic intervention. Treatment of cancer patients with thiol-containing antioxidants may improve the quality of life.

Loss of lean tissue often accompanies human immunodeficiency virus (HIV) infection. Exogenous human recombinant GH (hrGH) has been shown to be beneficial in reversing this wasting. However, catabolic effects of hrGH on muscle protein metabolism have also been reported. Therefore, the responsiveness of other GH-sensitive tissues, including bone formation and albumin synthesis, has been examined. Anabolic activity in bone, from serum levels of carboxy-terminal propeptide of type I collagen, was stimulated by 2 weeks of hrGH in controls (56 +/- 15%, P = 0.002), patients with asymptomatic HIV (24 +/- 10%, not significant), patients with AIDS (47 +/- 7%, P < 0.001), and patients with AIDS and > 10% weight loss (21 +/- 12%, P = 0.02). Albumin synthesis, determined from the incorporation of L-[2H5]phenylalanine, was increased in response to hrGH in controls (23 +/- 7%, P < 0.05), HIV+ subjects (39 +/- 16%, P < 0.05), and patients with AIDS (25 +/- 7%, P < 0.01). Patients with AIDS and weight loss, however, did not increase albumin synthesis (-0.6 +/- 12%) in response to hrGH. The results indicate variable anabolic responses to hrGH. Bone collagen synthesis remained sensitive to hrGH, whereas, the anabolic action of hrGH on the synthesis of albumin diminished with severity of disease. However unlike muscle protein synthesis, albumin synthesis was not depressed below basal levels by hrGH.

Arsenicosis is presently one of the significant public health problems in Bangladesh. Employing household screening of over 3.6 million people living in 6 arsenic-affected Upzilas of Bangladesh, 1,503 arsenicosis patients were identified at first and then blood and urine were collected from some of them and analyzed through laboratory techniques. As the relation between blood and urine chemicals with duration of having arsenicosis (DHA) is not clear, this study presented all findings by shorter versus longer DHA. Complications namely chronic bronchitis, conjunctivitis/congestions, weakness, and wasting were common, with relatively higher rates in longer group. Logistic regression analysis adjusted for age, sex, education, smoking, duration of drinking tube-well water, and whether any arsenicosis patients were in the family-indicated higher odds ratio (OR) of longer DHA (LDHA) in 3rd tertile with respect to GOT (OR = 2.12; 95%CI: 1.09-4.13), and blood glucose (OR = 2.00; 95%CI: 1.07-3.72) than 1st tertile. The OR of LDHA was significantly lower (OR = 0.48; 95%CI: 0.25-0.93) in 3rd tertile for triglycerides compared with 1st tertile. Albumin/globulin (A/G) ratio of 2nd tertile showed significantly lower OR of LDHA (OR=0.51; 95%CI: 0.28-0.95) than 1st tertile. Further epidemiological investigations based on a large sample, through cohort or case control studies, may be useful for validating and generalizing the results in Bangladesh.

Serum transthyretin (TTR), also known as prealbumin, is a reliable nutritional indicator and an independent prognostic factor for maintenance hemodialysis patients. However, we recently reported that serum TTR levels did not affect protein-energy wasting (PEW). In this study, we investigated factors affecting serum TTR levels in 60 maintenance hemodialysis patients. The patients were divided into High-TTR and Low-TTR groups according to the median serum TTR level. Albumin levels were significantly higher and C-reactive protein (CRP) levels were significantly lower in the High-TTR group than in the Low-TTR group. Although body fat mass was significantly higher in the High-TTR group than in the Low-TTR group, no significant difference in body fat ratio were observed. These findings suggest that body fat mass is related to serum TTR levels, apart from factors such as albumin and CRP levels, which showed correlations with serum TTR levels. Because body fat mass is related to better survival in maintenance hemodialysis patients, it may contribute to the prognostic value of serum TTR levels. In addition, in such patients, it may be important to evaluate body fat mass rather than body fat ratio and to maintain the minimum necessary body fat mass. J. Med. Invest. 64: 222-227, August, 2017.
