Abstract
A protein-energy deficit produces stress in the organism affecting all systems. Proportional to the degree of disease, cortisol and GH are mostly responsible for some of these effects. To investigate the effects on liver and bone, cortisol, GH, AST, ALT, ALP activities and Ca(T) and P(i) in serum were measured in 21 marasmus, nine kwashiorkor and 34 control children. In the marasmus group, we found a positive correlation between cortisol and AST, ALT and Ca(T) and a negative correlation between cortisol and ALP. In the kwashiorkor group there were positive correlations between the same parameters, although, they were of a lesser degree. Furthermore, in the kwashiorkor group we established a positive correlation between GH and ALP. Cortisol stimulates transaminases directly and suppresses ALP activity, thus indirectly increasing Ca(T), whereas GH has no direct effect on these enzymes. As the disease progresses and as liver functions deteriorate, AST, ALT and ALP increase in serum.

Abstract
Fasting serum lipids in children presenting with protein-energy malnutrition were studied in comparison with those of sex- and age-matched well nourished controls. There was no difference in serum total cholesterol between malnourished and well nourished children. However, serum triglyceride and phospholipid concentrations were significantly higher in children with kwashiorkor or marasmic kwashiorkor than in well nourished controls. It appears that serum concentrations of triglycerides and phospholipids increase with increasing severity of malnutrition, and that fasting serum triglyceride and phospholipid concentrations above 3 mmol/l are jointly predictive of a poor prognosis in malnourished children.

Abstract
Severely malnourished young children (n = 72) were treated with intravenous fibronectin to assess its efficacy as an adjunct treatment for kwashiorkor and/or marasmus. The protein was given in a double-blind study during the first 4 d of hospitalization together with standard nutrition and supportive therapy. Fibronectin concentrations as well as albumin, transferrin, prealbumin, and alpha-2-macroglobulin were monitored in samples taken before each dose of fibronectin and in samples taken five times thereafter. Sick individuals had significantly lower concentrations of all five proteins than did healthy control individuals of matching ages. Mean fibronectin concentrations were 98 +/- 7 mg/L (mean +/- SEM) for sick vs 303 +/- 21 mg/L for healthy individuals. Concentrations of all five proteins increased at a greater daily rate in patients treated with fibronectin than in patients who received placebos. Eighty-seven percent of the treated children survived to the end of the treatment and observation periods (mean hospitalization 14.7 d) whereas only 56% of the control subjects survived (P = 0.004). These data support the use of intravenous fibronectin as an adjunct in the treatment of severe malnutrition at a dosage of 7.5 mg.kg-1.d-1 over a 4-d period.

Abstract
The fatty acid composition of erythrocyte membrane (EM) lipids obtained from normal, kwashiorkor, and marasmic children was analyzed by gas chromatography. The proportion of palmitic acid (16:0) was lower and of oleic acid (18:1) higher in the kwashiorkor group than in the control group. The marasmic group showed lower proportions of eicosatrienoic acid (20:3) and arachidonic acid (20:4) and a higher proportion of oleic acid (18:1) than the control group. A significant difference was found between the marasmic and kwashiorkor groups with respect to arachidonic acid (20:4), which showed a lower proportion in the former group than the latter. The ratio of arachidonic acid to linoleic acid (20:4/18:2) was markedly lower in the marasmic group than the control group, suggesting a possible impairment in the conversion of linoleic acid to arachidonic acid in marasmic children. The ratio of unsaturated fatty acids to saturated fatty acids was markedly elevated in the kwashiorkor group over that of control group, indicating increased fluidity of EM in kwashiorkor. It is suggested that the altered membrane fatty acid composition reflects deranged lipid metabolism and affects the physical and physiological properties of EM and could contribute to changes in the activities of several red blood cell membrane-bound enzymes reported earlier in kwashiorkor children.

Abstract
Calpain, a calcium-dependent, neutral cysteine-protease was purified from the erythrocyte cytosol of subjects having essential hypertension (HTN), sickle cell anaemia, (SCA), or kwashiorkor (KWA). Identical electrophoretic mobility on SDS-polyacrylamide gradient gel, sensitivity to micromolar amounts of Ca2+, absolute requirement for a reducing environment and a high susceptibility to inhibition by leupeptin and thiol-group modifying reagents confirm that calpain preparations from these erythrocytes are equivalent to calpain I. Whereas the extent of calpain activation of erythrocyte membrane Ca2(+)-pumping ATPase of normal subjects was almost equal to that due to calmodulin, calpain activation of the HTN and SCA pump was greater than activation by calmodulin. Like in normal membranes, exogenous calmodulin protected the Ca2(+)-pumping ATPase of these erythrocytes against calpainization; the degree of protection by calmodulin is least in SCA and HTN. Electrophoretic separation of erythrocyte membranes and the purified Ca2(+)-pumping ATPase of HTN, SCA and KWA subjects does not indicate the presence of fragments resulting from the proteolytic action of calpain.

Abstract
Red cells in oedematous malnutrition (kwashiorkor) have an increased sodium content, 'leakiness' to sodium and enhanced sodium pumping. In non-oedematous malnutrition (marasmus) there is a reduction in the sodium pump activity. The explanation has hitherto been unknown but the glutathione content of red cells is low in kwashiorkor and normal in marasmus. We artificially lowered the glutathione content of normal red cells to values characteristic of mild oedematous malnutrition, using the enzyme inhibitors bischloronitrosourea (BCNU) and buthionine sulfoximine (BSOX). After preincubation, the cells were washed to remove the inhibitors and oxidized glutathione. Cellular content of sodium and potassium, and 86Rb influx were then measured. The reduction in glutathione reproduced the abnormalities of sodium content and flux observed in kwashiorkor. We suggest that oxidant stress in kwashiorkor, by reducing cellular glutathione, may affect cell membrane electrolyte transport. This may act through alterations in membrane sulfhydryl groups. Glutathione depletion may therefore play an important role in the clinical picture and natural history of oedematous malnutrition and may have relevance to other conditions where oxidant stress occurs.

Abstract
We investigated the serum manganese (Mn) concentration of 52 children less than two years old. 22 of them were healthy controls (C), 13 had marasmatic (M) malnutrition and 17 kwashiorkor (K). The measurements of Mn were done in an atomic absorption spectrophotometer with a graft furnace oven. The serum was diluted with 1% triton X-100. For the quantification of Mn we used the addition method. There was a significant difference between the levels of Mn measured in the M group (1,582 +/- 0.673 micrograms/L), and the K group (1,811 +/- 0.700 micrograms/L) and levels obtained in the controls (3,212 +/- 1,247 micrograms/L). When we compared the concentration of Mn by sex or age in each group, we didn't find any significant difference. We conclude that the severe malnourished children in our study present lower concentrations of Mn as compared with controls.

Abstract
Total tocopherols and alpha-tocopherols were estimated in the plasma of children with severe malnutrition (14 marasmus; 11 marasmic kwashiorkor; five kwashiorkor) and related to the total plasma lipids and different plasma lipid classes. If the mere plasma concentrations were taken as an index of the vitamin E status, five children with marasmus, five children with marasmic kwashiorkor, and two children with kwashiorkor would have been regarded as deficient (less than 500 micrograms/dl). However, if total tocopherols and alpha-tocopherols were related to the total plasma lipids, all malnourished children--except one--showed values within the limits found in healthy American children. The study shows that low tocopherol/lipid ratios are not a constant feature in severely malnourished children.

Abstract
Prothrombin time, serum albumin, aminotransferases and liver size were evaluated in 40 consecutive cases of kwashiorkor. Eleven (27.5%) of the 40 patients died. Eight out of the 11 patients who died had a prolonged prothrombin time of more than 3 s above the control compared to only 4 out of the 29 who survived (p = 0.005). Mean serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) albumin, globulin and liver size were abnormal but similar in both groups. These results may indicate a predictive mortality value of prothrombin time in kwashiorkor.

Abstract
The serum protein binding of salicylic and salicyluric acid has been determined by ultrafiltration in 60 children after administration of oral salicylate. The children were classified according to nutritional status: well-nourished (n = 12), underweight (n = 12), marasmic (n = 17) marasmic-kwashiorkor (n = 7) and kwashiorkor (n = 12). Salicylic acid free fractions were 0.106 +/- 0.026, 0.114 +/- 0.069, 0.141 +/- 0.037, 0.285 +/- 0.279 and 0.438 +/- 0.190 in the five groups, respectively. Salicyluric acid free fractions were 0.184 +/- 0.057, 0.280 +/- 0.282, 0.236 +/- 0.114, 0.484 +/- 0.497 and 0.646 +/- 0.261, respectively. The degree of binding was dependent on serum albumin levels, ligand concentrations and non-esterified fatty acids (NEFA). The NEFA/albumin ratio ranged from 0.05 to 6.6. The fitting of a one-site Scatchard binding model to the collective data was improved when a decrease was allowed for in the number of binding sites in proportion to NEFA concentrations. Salicyluric acid binding could be fitted only when inhibition of the parent compound was included. Binding was not affected by age or sex. The major determinants of salicylate binding in sera from malnourished children have thus been identified.

Abstract
Calmodulin-free ghost membranes were prepared from erythrocytes of kwashiorkor children and from healthy children in the same age bracket. In the absence of calmodulin, the specific activity of Mg2+-dependent Ca2+-pumping ATPase (Ca2+ + Mg2+-ATPase) of kwashiorkor membranes was more than 40 percent lower than the specific activity of the normal enzymes, whose maximum velocity was increased by at least four-fold by the modulator protein. In contrast, the maximum velocity of the enzymes of kwashiorkor membranes was enhanced by calmodulin by about 1 1/2 times the basal activity of the normal enzymes and by 2 times the basal activity of the kwashiorkor enzymes. The affinity of the pump for ATP was lower in the membranes of kwashiorkor children (Km for ATP = 30.6 +/- 2.8 microM ATP) in comparison to normal membranes (Km for ATP = 21.7 +/- 2.0 microM ATP). Similarly, calmodulin-affinity of the enzymes, was lower in kwashiorkor membranes than in the normal membranes irrespective of source of calmodulin. Calmodulin from haemolysates of kwashiorkor red cells activated the enzymes of normal and kwashiorkor membranes to the same degree as calmodulin partially purified from the haemolysate of healthy children. A determination of the dependence of the activity of the pump on calcium in the absence and presence of calmodulin reveals that the affinity of the kwashiorkor enzymes for Ca2+ is at least 70 percent lower than that of enzymes of normal membranes. Altogether, these findings suggest that the Ca2+-pumping ATPase of kwashiorkor membranes is less functional than the enzymes of healthy erythrocytes.

Abstract
The plasma concentration of INH and streptomycin was followed in 45 Ethiopian children with tuberculosis. The children were grouped according to their nutritional status as normal, underweight, marasm and kwashiorkor. INH was well absorbed in all nutritional groups to give therapeutically active plasma levels. When terminal half life (t1/2) of INH was calculated for individual patients there were more children in all nutritional groups with t1/2 greater than or equal to 2 hours than less than 2 hours, indicating a slow acetylation of INH. Streptomycin was well absorbed in all nutritional groups and therapeutic levels were obtained with 20 mg/kg i.m. After 30 mg/kg i.m. of streptomycin kwashiorkor children had an increased t1/2 of streptomycin indicating a decreased renal excretion of the drug in kwashiorkor. The clinical follow-up of the children indicated that serious tuberculosis could be successfully treated with INH and streptomycin in the doses used.

Abstract
Erythrocytes of normal and malnourished children, both marasmic and oedematous (kwashiorkor), were equilibrated in standard incubation medium and their ion transport via the Na/K pump and the pathways of passive permeation were measured as unidirectional fluxes of 86Rb (as a congener of K) and 22Na. Cells of children with kwashiorkor exhibited a 65 per cent higher ouabain-sensitive K(Rb) influx ('pump rate') than those of normal or marasmic children. When allowance was made for cytoplasmic Na concentration, the pump rate was slower in younger (12 months and under) normal children than in older children. Judged by the same criterion, cells of older marasmic children also had slower steady-state pump activity. The passive permeation of K through the residual 'leak' pathway (ie, ouabain-and-bumetanide-insensitive influx) and Na permeation (ouabain-and-bumetanide-insensitive Na efflux) were greater in malnourished children than in normal children by a factor of two or more. During treatment for malnutrition, both Na-pump activity and ouabain binding increased rapidly in marasmic children. Passive permeation did not return to normal levels in malnourished children during the period of hospitalization.

Abstract
Aflatoxin analyses were undertaken on sera and urines of 41 children admitted to a rural hospital in Kenya with kwashiorkor, marasmus, marasmic kwashiorkor or normal nutrition (Wellcome Classification). Aflatoxins were detected most frequently and at highest concentrations in the sera of kwashiorkors who, conversely, showed aflatoxins least frequently in their urine and in concentrations that were disproportionately low compared with serum/urine aflatoxin levels in other groups. These findings indicate altered aflatoxin metabolism in kwashiorkor and support the hypothesis that there are special relationships between aflatoxins and kwashiorkor.

Abstract
Serum alpha 2 HS-glycoprotein levels were studied, using the single-radial immunodiffusion method, in 39 severely malnourished children (22 kwashiorkor, 17 marasmus) of whom 15 (8 kwashiorkor, 7 marasmus) were infected and 24 (14 kwashiorkor, 10 marasmus) had no signs of infection. Thirty-two well-nourished children, 16 of whom were infected, served as controls. The uninfected controls had higher serum alpha 2 HS-glycoprotein levels than the uninfected kwashiorkor (82.0 +/- 14.7; 57.0 +/- 15.8; p less than 0.001) and marasmic children (82.0 +/- 14.7; 45.0 +/- 13.9; p less than 0.001). Infection was associated with a significant decrease in the mean serum alpha 2 HS-glycoprotein levels in the well-nourished (82.0 +/- 14.7; 57.0 +/- 7.7; p less than 0.001) and kwashiorkor (57.0 +/- 15.8; 34.0 +/- 20.4; p less than 0.02) children, while no such decrease was observed in the marasmic children. While the mean serum glycoprotein level in the infected controls was higher than that in the infected kwashiorkor children (57.0 +/- 7.7; 34.0 +/- 20.4; p less than 0.02), it was comparable to that in the infected marasmic children (57.0 +/- 7.7; 50.0 +/- 11.6; p greater than 0.05). Furthermore, the mean alpha 2 HS-glycoprotein level in the infected malnourished children was higher in marasmus than in kwashiorkor (50.0 +/- 11.6; 34.0 +/- 20.4; p greater than 0.05); this difference was, however, not statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Serum insulin, growth hormone (GH), insulin-like growth factors (IGFs) I and II, cortisol, and albumin concentrations were measured in 15 children with kwashiorkor, 15 with marasmic-kwashiorkor, and 21 with marasmus, before and in the survivors, after nutritional rehabilitation, as well as in 10 underweight and eight normal Egyptian children. We also evaluated arginine-induced insulin and GH secretion. IGF-I concentrations were reduced in the three severely malnourished groups (0.07 +/- 0.03, 0.05 +/- 0.03, and 0.09 +/- 0.09 U/ml, respectively) but returned to normal after refeeding. IGF-II concentrations were low in the kwashiorkor (175 +/- 79 ng/ml), marasmic-kwashiorkor (111 +/- 57 ng/ml), and marasmic children (128 +/- 70.9 ng/ml) and returned to normal after nutritional rehabilitation. Basal GH levels were high in the three severely malnourished groups (21.9, 28.8, and 16.6 ng/ml, respectively) and returned to normal after refeeding (8.1, 6.5, and 6.0 ng/ml, respectively). GH responses to arginine were depressed in the three malnourished groups and improved significantly in marasmic-kwashiorkor and marasmic children after nutritional rehabilitation. Insulin responses to arginine were impaired in kwashiorkor, and marasmic-kwashiorkor children and improved significantly after refeeding. IGF-I levels correlated significantly with percent of expected weight (r = 0.52, p less than 0.001), percent of expected height (r = 0.42, p less than 0.001), and weight/(height)2 index (r = 0.34, p less than 0.01). IGF-I levels correlated positively with insulin levels (r = 0.421, p less than 0.001) and negatively with cortisol concentrations (r = -0.400, p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
An attempt to use the relative concentrations of major plasma proteins for clinical assessment of severe malnutrition is described. Quantitative two-dimensional gel electrophoresis was used to measure the concentrations of 24 major proteins in small aliquots of plasma obtained from children, aged 0 to 3 years, who were patients and outpatients in Liberian hospitals. Fifteen had a clinical diagnosis of kwashiorkor, 36 were diagnosed with marasmus, and 18 were controls. There were also 5 controls from the United States. The individuals were placed in six groups; kwashiorkor, kwashiorkor who died during treatment, marasmus, marasmus who died, Liberian controls, and U.S. controls. The amount of protein in each spot in the two-dimensional gels was estimated by measuring bound stain using a laser scanner and computerized image analysis. We found very low serum transferrin levels in malnourishment, in agreement with reports from other investigators. All of the data for 24 protein variables were pooled for factor analysis; the mean factor scores for each group differed, with the kwashiorkor groups furthest from the controls. Results of discriminant analysis using the amounts of different numbers of protein variables (3 to 24) were compared for posterior assignment of individuals to groups. The validity of the method was tested by analysis of plasma aliquots obtained from patients following initiation of therapy and which were not a part of the training set. Predictive performance (prognosis of patient survival) depended upon the number of protein variables used. Although artifactual fitting of the data is expected to contribute to performance as the number of variables is increased, use of as many as 7 variables may be justified, even with our small patient groups. Possible use of these results for development of a practical clinical test is discussed.

Abstract
As life expectancy increases, so do the problems of the elderly population. One major problem is that of protein calorie malnutrition; another is the susceptibility of this population to pressure sores. The purpose of this study was to determine if a correlation exists between deteriorating nutritional status and the development of pressure sores. The nutritional status of 232 nursing home patients (mean age 72.9 +/- 12 years) was determined using biochemical and anthropometric measurements. Overall, the incidence of some degree of malnutrition was 59%. Seventeen of the patients were found to have pressure sores and were all malnourished. When classified as mild, moderate, or severe malnutrition, the patients with pressure sores were in the severe group. There was a significant difference (P less than .001) between the nutritional status of pressure sore patients and the malnourished patients. It appears that the development of pressure sores correlates with nutritional deficiencies. The authors' findings suggest a need for more aggressive nutritional support in the elderly, especially those with pressure sores.
