Delayed nerve conduction velocities in children with protein-calorie malnutrition.

Protein-calorie malnutrition in human beings and animals affects the myelination and growth of the nervous system. The effects of PCM on the developing nervous system were evaluated by measuring the nerve conduction velocities in 93 (38 marasmus, 13 kwashiorkor, and 42 control) children in ulnar, median, peroneal, and posterior tibial nerves. The children were divided into three age groups: Group I, six to 12 months; Group II, 13 to 24 months; Group III, 25 to 48 months. All 13 children with kwashiorkor demonstrated irritability, delayed milestones, and muscular wasting; and six also had hypoactive muscle reflexes. Conduction velocities were reduced in each type of malnutrition, with statistically significant differences in the three groups of marasmic children and in Group III kwashiorkor children. Children with kwashiorkor in Group II had significantly reduced velocities only in the nerves of the lower extremities. These data suggest PCM, when it occurs during the development of the nervous system, affects myelination of the peripheral nerves.

Selenium serum concentrations in malnourished Ecuadorian children: a case-control study.

Little is known about the selenium status of children living in the Andean regions of South America, which commonly have volcanic soil with low selenium content. Human selenium deficiency has been hypothesized to have a negative impact on immune function and to increase the risk of infection. The objective of this study was to evaluate the serum selenium concentrations of severely malnourished children living in urban and rural Andean Ecuador, and to compare them to a control group of normally nourished children from the same communities. Forty-three children, aged six to 36 months, with marasmus or kwashiorkor and 30 control children were enrolled from July to November 1993 in Quito, Ecuador. Serum selenium concentrations were lower in the children with marasmus (0.91 +/- 0.28 microM/L, n = 21) and kwashiorkor (0.37 +/- 0.15 microM/L, n = 22) than in those who were normally nourished (1.77 +/- 0.75 microM/L, n = 30, p < 0.001 for each difference). The serum selenium concentrations in children with kwashiorkor were significantly lower than those in children with marasmus (p < 0.001). All 22 of the children with kwashiorkor, 15 of the 21 children with marasmus, and five of the 30 normal children had serum levels < 1.08 microM/L (8.5 micrograms/dL) (chi 2 = 38.4, p < 0.00000001). In the Andean regions of Ecuador, selenium deficiency is prevalent in children with protein and caloric deficiency. Furthermore, 17% of Ecuadorian children with normal weight-for age-Z score are selenium-deficient.

Lymphocyte proliferation kinetics in malnourished children measured by differential chromatid staining.

1. Utilizing the bromodeoxyuridine differential-chromatid labelling technique the in vitro proliferation of lymphocytes from children with kwashiorkor was followed in phytohaemagglutinin-stimulated cultures and compared with controls. 2. Analyses of first, second and third or subsequent division cells as a function of culture time between 40 and 96 h showed that cell-cycle duration was prolonged in kwashiorkor cultures. The extent of this increase was approximately 4.5 h for the first-division cells and 1.5 h for third-division cells. 3. The peak for second-division cells was depressed in kwashiorkor cultures. 4. A decreased number of third or subsequent-division cells was observed in kwashiorkor cultures at all time points studied. 5. These findings suggest that the loss in lymphocyte activity to PHA in malnourished children in general could be due to an increase in cell-cycle duration of responding lymphocytes.

Aflatoxins in autopsy kidney specimens from children in Nigeria.

Autopsy kidney specimens from 24 children with kwashiorkor and 21 with other miscellaneous diseases, at the Obafemi Awolowo Teaching Hospital Complex, Ile-Ife, Nigeria, were analyzed for the presence of aflatoxins using high-performance liquid chromatography. Aflatoxins were detected in 14 children who died of kwashiorkor and in 13 of those who died from miscellaneous diseases. Aflatoxicol was detected in 10 specimens, 7 of which had severe gastroenteritis. Seven kidney specimens demonstrated the presence of more than one type of aflatoxin; four of these were kidneys of patients with kwashiorkor and the remaining three died from renal failure. No difference was found between the frequency of detection, type of aflatoxin detected, or mean concentrations of total aflatoxins in the kidney specimens of the kwashiorkor children when compared to the kidney specimens of children who died from miscellaneous diseases. These findings demonstrate that aflatoxins can be detected in the kidneys of children exposed to aflatoxins.

The effect of nutritional support on T-lymphocyte subpopulations in protein calorie malnutrition.

T-lymphocyte subpopulations were measured in the two major types of adult malnutrition, adult marasmus and kwashiorkor-like hypoalbuminemic malnutrition. The population of T-cells (T3) and the percentage of both helper (T4) and suppressor (T8) T-cells were significantly (P less than .05) decreased in patients with kwashiorkor-like hypoalbuminemic malnutrition, but did not differ from control values in patients with adult marasmus. The ratio of helper T-cell (T4), to suppressor T-cells (T8) (range 1.2-1.6) did not vary from control values in either type of malnutrition. One week of nutritional support was not associated with a significant increase in any of the T lymphocyte subpopulations in either type of malnutrition. These T-cell subpopulation changes are consistent with the greater depression of cellular immune function seen in patients with metabolic stresses associated with kwashiorkor-like hypoalbuminemic malnutrition. With the increasing frequency in which abnormalities of T-cell subpopulations are being reported in various diseases, the coexistence of kwashiorkor-like hypoalbuminemic malnutrition should be noted for its potentially confounding effect.

Erythrocyte membrane Na+ and K+ activated adenosine triphosphatase in protein-calorie malnutrition.

Total, ouabain insensitive and ouabain sensitive Na+ and K+ adenosine triphosphatase activity in the erythrocyte membrane of protein-calorie malnourished children with marasmus and kwashiorkor was compared with the enzyme activity in apparently healthy children (normals). Na+ and K+ contents of erythrocyte and plasma were also determined in these patients. Specific activity (units per milligram of membrane protein) of ouabain sensitive Na+ and K+ adenosine triphosphatase was significantly higher in erythrocyte membrane preparations from children with kwashiorkor but not from children with marasmus. After 4 to 5 weeks of treatment with diets sufficient in protein and calories the specific activity of the enzyme was lower as compared to that on admission. Erythrocyte and plasma Na+ content (microgram/10(6) cells and microgram per milliliter of plasma) in children with kwashiorkor were not different from those in normal children, however, there was reduction in K+ content of erythrocytes and plasma of these children. After treatment, erythrocyte Na+ and K+ and plasma K+ in children with kwashiorkor increased significantly. In marasmic children erythrocyte Na+ was higher as compared to normal but there were no differences in K+ content of either eyrthrocytes or plasma in these children.

The pattern of severe protein-calorie malnutrition in Sudanese children attending a large hospital in The Sudan.

One hundred fifty patients suffering from severe protein-calorie malnutrition, admitted in 1 month to the Pediatric wards of Wad Medani Hospital, Sudan, were classified according to the Wellcome classification. Marasmus was the prevailing type. It was common in the 2nd year of life, while kwashiorkor occurred mainly under the age of 12 months. Anthropometric measurements showed that kwashiorkor was an acute disease while marasmus and marasmic kwashiorkor were more chronic. The triceps skinfold was unexpectedly low in kwashiorkor. Of the simple measurements and ratios used for assessing the nutritional status, the head/chest ratio applied ot children over 1 year was not found to be reliable and the weight for head circumference correlated poorly with deficits in other variables. Non of the major clinical features was found to be pathognomonic of any type of severe protein-calorie malnutrition. Megaloblastic anemia was common.

Influence of nutrition on postvaccinial tuberculin sensitivity.

Response to BCG vaccination was studied in 261 apparently normal preschool children in a community. They were classified into different nutritional groups based on deficit in weight for age. In addition, nine children who had kwashiorkor and were admitted to the hospital were investigated. They were given 0.1 ml of BCG vaccine, and 6 months later, tuberculin sensitivity was assessed using 5 U of PPD. Blood samples were collected from 84 subjects and leukocyte migration inhibition was determined using the same antigen. After BCG vaccination, over 80% of children in the community showed positive tuberculin test, irrespective of the extent of growth retardation. There were no significant differences in the size of induration or the percentage of reactors between the various groups, indicating that the immune response to BCG vaccination is not affected by milder grades of malnutrition. However, the skin test was negative in most of the children who had had kwashiorkor. Leukocyte migration inhibition was similar in all the groups of children including those with kwashiorkor indicating that sensitisation of lymphocytes was not influenced by the nutritional status. In children with kwashiorkor, the leukocyte migration inhibition test was positive though the skin test was negative, suggesting that the former may be a better measure of assessing the response to BCG vaccination.

Exocrine pancreatic function and protein-calorie malnutrition in Dakar and Abidjan (West Africa): silent pancreatic insufficiency.

Pancreatic function was measured by duodenal aspiration after injection of secretin and cholecystokinin in malnourished children from Dakar and Abidjan, West Africa, and in age- and sex-matched control subjects from Dakar, Abidjan, and Marseille, France. Compared with French control subjects, pancreatic function was moderately decreased in Abidjan control subjects and more severely in Abidjan subjects with kwashiorkor. Pancreatic insufficiency was as severe in patients as in control subjects in Dakar. After a well-balanced diet was fed for 5 d, all kwashiorkor symptoms disappeared. In Abidjan pancreatic secretion levels increased but remained lower than in control subjects. After 28 d feeding, the pancreatic secretion of kwashiorkor patients in Dakar was not modified. Pancreatic extracts had no effect on changes in pancreatic insufficiency after feeding. In West Africa there is a latent pancreatic insufficiency involving water, electrolytes, and enzymes, which is more severe in Dakar, where, in contrast to Abidjan, it is neither aggravated by kwashiorkor nor corrected by feeding.

Plasma lipids and lipoproteins in protein-calorie malnutrition.

Plasma triglycerides, phospholipids and total cholesterol estimations and lipoprotein electrophoresis on agarose gel were done in control, Kwashiorkor, and marasmic kwashiorkor children. The beta lipoprotein percentage in both conditions is reduced to a statistically significant extent, whereas there is a statistically significant increase in plasma triglycerides in both conditions. Pre-beta fraction was present in all cases, and even increased in marasmic kwashiorkor, which is found to be significant. The results do not support the hypothesis that fatty liver in kwashiorkor is due to impaired release of triglycerides from liver.

Prevalence of aflatoxins in blood and urine of Egyptian infants with protein-energy malnutrition.

The aim of the present work was to study the presence of aflatoxins in blood and urine of infants with protein-energy malnutrition (PEM). The study was conducted on 60 infants, 30 with kwashiorkor and 30 with marasmus, with 10 age-matched healthy infants studied as a control group. Complete blood count, liver function tests, and determination of the level of aflatoxins (B1, B2, G1, G2, M1, M2, G2a, B3, GM1, P, and aflatoxicol R0) in blood and urine were carried out in all studied infants. Serum aflatoxins were detected in more infants with kwashiorkor (80%) than in those with marasmus (46.7%). The mean serum levels of total aflatoxins, AFB1, AFG1, and AFB2a, were significantly higher in infants with kwashiorkor (p <.001). Aflatoxin B1 (AFB1) was the most commonly detected type. The prevalence of aflatoxin excretion in the urine of infants with kwashiorkor was 80%, a higher value than that in infants with marasmus (46.7%). The mean urinary concentration of total aflatoxins followed the same pattern of distribution (p < .052). There were no significant differences between groups in the mean urinary concentrations of AFB1, AFG1, AFB2a, AFM1, and AFG2a. Aflatoxins were not detected in any of the serum or urine samples of the control group. Aflatoxins are highly prevalent in this study population and show a high degree of correlation with severe PEM.

Plasma and red blood cell fatty acid composition in children with protein-calorie malnutrition.

Plasma and red cell fatty acids were measured in 44 children with third degree malnutrition: 22 children with marasmus, 11 children with kwashiorkor, and 11 with marasmic kwashiorkor (MK). The presence of edema, dermatosis, hair changes, and hypoalbuminemia were positively correlated with the red cell percentage linoleic acid and negatively correlated with red cell percentage arachidonic acid. Red cell percentage linoleic acid in kwashiorkor was decreased from the control value of 15.3% to 10.9%. In marasmus and MK, there were significantly greater decreases, to 7.7% and 8.0%, respectively. Red cell arachidonic acid in kwashiorkor was significantly (P less than 0.001) decreased to 9.8% (control value of 13.1%) whereas in marasmus there was no significant change. Only one sample, plasma from an infant with marasmus, had any detectable eicosatrienoic acid (20:3,omega 9). Similar changes in fatty acid composition have been reported in infants with acrodermatitis enteropathica, in an infant with biotin deficiency, and in biotin-deficient rats.

Serum thyroid hormone and thyroid gland weight measurements in protein-energy malnutrition.

Protein-energy malnutrition (PEM) is a problem which concerns about half the world's children. We investigated the effects of malnutrition on thyroid gland weight and thyroid hormone levels. 22 children suffering from malnutrition (14 children suffering from marasmus and 8 children suffering from kwashiorkor) and 7 healthy controls were studied. Malnutrition was confirmed clinically and according to the Wellcome classification definition of malnutrition. Serum thyroid hormone concentrations were measured by radioimmunoassay and the weights of the thyroid gland were evaluated scintigraphically. In the groups with marasmus and kwashiorkor the mean TT4, TT3 and FT3 levels were significantly lower, and TSH levels were significantly higher, compared to controls. FT4 was not influenced by PEM. The mean thyroid gland weights of the groups with marasmus and kwashiorkor were higher than that of the control group. We found no significant differences in all these parameters between groups with marasmus and kwashiorkor. In each of the three groups, the most marked positive correlation was between thyroid gland weight and ratio of thyroid gland weight to body surface area.

X-ray diagnosable pneumonia in children with severe malnutrition at Kenyatta National Hospital.

OBJECTIVES: To estimate the prevalence of radiologically evident pneumonia among children with severe malnutrition and to evaluate the diagnostic utility of commonly used clinical indicators of pneumonia among children with severe malnutrition. METHODS: All children with severe malnutrition and admitted at the then Paediatric Observation Ward without congestive cardiac failure, severe anaemia, or severe dehydration, were clinically evaluated and a posteroanterior chest X-ray taken for each child. Pneumonia was diagnosed on the basis of radiological changes consistent with pneumonia as reported by an experienced radiologist. The performance of the various clinical parameters as diagnostic tests for pneumonia were also evaluated. SETTING: Kenyatta National Hospital, a tertiary level teaching institution for the University of Nairobi. RESULTS: One hundred and seven children comprising 68 males and 39 females were recruited into the study. Of these children, 38 had kwashiorkor, 40 had marasmus, while 29 had marasmic kwashiorkor. Radiological evidence of pneumonia was found in 58% of children with kwashiorkor, 75% with marasmic kwashiorkor, and 82% with marasmus. All the commonly used clinical parameters performed poorly as diagnostic tests for pneumonia among children with severe malnutrition. CONCLUSION: Prevalence of pneumonia was very high among children with severe malnutrition. Available clinical parameters, singly or in combination, are poor diagnostic tools for pneumonia in children with severe malnutrition. It is advisable to treat children with severe malnutrition as if they had pneumonia, even in the absence of suggestive clinical signs.

Plasma electrolytes, total cholesterol, liver enzymes, and selected antioxidant status in protein energy malnutrition.

Golden and Ramdath proposed the free radical theory of kwashiorkor, suggesting that the changes seen in kwashiorkor may be the result of an imbalance between the production and safe disposal of free radicals. In malnourished children, mineral metabolism and antioxidant status need renewed attention especially in relation to cause and functional significance of the changes in concentration of these substances. In the present study, the modified Wellcome classification was used to classify the protein energy malnourished children into kwashiorkor marasmic-kwashiorkor, marasmus and underweight. Twenty-six healthy and normal children were used as controls. Standard procedures were used for the analyses of the biochemical parameters. Our results showed that plasma total cholesterol, sodium, potassium and bicarbonate, beta-carotene, retinol and uric acid were significantly lower in the malnourished group than the control group (P < 0.05), while transaminases were significantly increased in the malnourished group (P < 0.05). These findings suggest an altered electrolyte and antioxidant status in protein energy malnutrition.

Plasma biochemical parameters in Nigerian children with protein energy malnutrition.

Eleven plasma biochemical parameters were estimated in a total of 28 children with protein-energy malnutrition (PEM): 7 children each category of marasmus, kwashiorkor, marasmic-kwashiorkor and undernutrition with ages between 8 and 48 months. The estimations were performed on admission and 8 to 24 days after treatment at the Obafemi Awolowo University Teaching Hospitals Complex, Nigeria. Plasma sodium, potassium, chloride, bicarbonate and albumin levels were significantly (p < 0.05) higher after treatment than on admission. Calcium however, showed no significant change. Total protein and cholesterol were significantly (p < 0.05) raised after treatment for all the PEM types except undernutrition and kwashiorkor respectively. Globulin, urea and creatinine were significantly (p < 0.05) raised after treatment for kwashiorkor. These biochemical findings support the claims of clinical improvement in PEM children after a minimum of 18 days of treatment at the OAUTHC in Nigeria.

Reduction in vitro of red cell glutathione reproduces defects of cellular sodium transport seen in oedematous malnutrition.

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.

Severe protein energy malnutrition in Lesotho, death and survival in hospital, clinical findings.

In Lesotho's central hospital 55 (25%) of 218 admissions for severe PEM died during 1981 and 1982. Most deaths (62%) occurred in the first week. The most important causes of death were acute GE and pneumonia in marasmus and kwashiorkor, respectively. The cause of death remained obscure in 16 children, however. In marasmus a poor prognosis was significantly associated with the finding on admission of a temperature less than 36.5 degrees C (P less than 0.05), apathy (P less than 0.01) and a depigmented skin (P less than 0.05), while in marasmic kwashiorkor only the finding of the latter was significantly (P less than 0.05) associated with death. In non-survivors with kwashiorkor the following characteristics were observed significantly more often: complaints of diarrhoea and/or vomiting on admission (P less than 0.05), the finding of apathy, pallor, skin defects and hepatomegaly on admission (P less than 0.01), and the finding of a low serum albumen, Na+ and K+ in the first days (P less than 0.05). Irritability was significantly (P less than 0.05) more common in survivors with kwashiorkor. Xerophthalmia was observed only once. Infections were diagnosed in 86% of all and giardiasis in 28% of 146 children. Twenty-eight children contracted measles of whom 5 died. Severe PEM still carries a high mortality despite hospitalisation. The findings confirm the need for intensive management of severe PEM.
