The serum concentrations of the acute phase proteins, C-reactive protein, caeruloplasmin and haptoglobin were significantly higher in children with protein-calorie malnutrition than in age-matched controls, while the concentrations of alpha1 antitrypsin, alpha2 macroglobulin, transferrin and complement component C3 were significantly lower. During rehabilitation and treatment with antibiotics, C-reactive protein disappeared from the serum in most of the patients whilst the levels of caeruloplasmin and haptoglobin returned to normal values. On the other hand the serum concentration of alpha1 antitrypsin, alpha2 macroglobulin, transferrin and C3 showed significant increases. It is suggested that C-reactive protein and haptoglobin may provide useful indices of the presence or absence of infection in children with malnutrition.

Following extensive bowel resection, a young woman experienced severe malnutrition; subsequent administration of parenteral nutrition precipitated the copper deficiency syndrome. This consisted of hypocupremia, subnormal ceruloplasmin levels, anemia, and severe neutropenia. The bone marrow was megaloblastic, vacuolated, and sideroblastic; granulocytic maturation was not observed beyond the myelocyte stage. Copper sulfate therapy was followed by a marked reticulocytosis, increase in hematocrit, and recovery of neutrophils. Additional studies indicated that both serum and urinary erythropoietin values were low; serum activity increased after copper supplementation. Abnormal granulopoiesis was demonstrated using the in vitro granulocyte colony assay. The patient's granulcoytic stem cells were normal on two occasions; however, mixing studies showed that culture of the patient's copper-deficient marrow with her copper-deficient serum yielded significantly reduced numbers of granulocyte colonies. Thus, copper appears to be a necessary element for normal hematopoiesis; lack of this trace element may result in ineffective erythropoiesis and granulopoiesis.

In order to study the relationship between nutritional status and immunity, certain biochemical and immunological parameters were examined in 53 children with mild or severe malnutrition and 35 normal controls. The levels of hemoglobin, total serum protein and complement (C'3) were not affected by malnutrition. There was a significant depression of serum albumin, transferrin and ceruloplasmin in the severely malnourished children. Serum IgM, IgG and IgD were normal in both malnourished groups. The level of serum IgA was elevated only in the severely malnourished children. The proportion of B cells was the same in all groups; howver, the frequency of T cells was reduced in the severely malnourished cases.

Changes in lipid peroxidation parameters (LP), antioxidant system and proteinase inhibitors were studied at different evolutionary stages of experimental osteoarticular tuberculosis in 30 rabbits. All stages of the process were characterized by LP activation which in animals of all groups (except rabbits having the acute stage of arthritis) is accompanied by compensatory increase of superoxide dismutase and ceruloplasmin activity. Deficiency of superoxide dismutase found in the acute stage of arthritis with a growth of LP activity shows its inadequate production at a given stage of articular inflammation. Decrease in alpha 1-proteinase inhibitor activity at the stage of osteitis with reactive synovitis can be caused by the influence of LP products. The importance of this mechanism in the inhibition of alpha 1-proteinase inhibitor, together with reduction in its production at the acute stage of arthritis, cannot be ignored. The results obtained make it possible to recommend further study of the perspectives of antioxidants use in osteoarticular tuberculosis.

Based on the findings that the enhancement of serum alpha 2-macroglobulin (A2M) is associated with the occurrence of infectious complications following surgery in patients with esophageal cancer, we examined possible factors which could contribute to the alterations of serum acute phase protein levels in patients with this disease. A multiple linear regression analysis was made for 71 patients with esophageal cancer and 58 with gastric cancer. In patients with esophageal cancer, protein calorie malnutrition (PCM) and age factors more strongly contributed to the alteration of 6 acute phase protein levels than did the malignant tumor when compared to those with gastric acner. PCM was negatively associated with A2M levels while it was positively associated with alpha 1-acidglycoprotein (A1AG) and haptoglobin (Hp) levels. Age did not contribute to the A2M levels but did have a negative effect on the Hp, ceruloplasmin (Cp) and fibronectin (Fn) levels. On the other hand, the malignant tumor was positively related only to the A1AG levels. Since none of these factors contributed to the elevation of A2M levels, it is suggested that the presence of chronic infection might be a factor contributing to the A2M increase which was associated with the occurrence of postoperative infectious complications in patients with this disease.

The study comprised 40 children of both sexes aged from 2 to 12 years, 22 suffering from bronchial asthma and 18 suffering from atopic dermatitis. Twenty healthy children of comparable age and sex to the patients were studied as controls. All the children were subjected to full history including dietetic questionnaire, thorough examination, and to estimation of serum IgE, serum ceruloplasmin, and zinc and copper levels in both serum and hairs. The mean concentrations of zinc in serum and hairs were respectively 70.3 +/- 13.2 micrograms/100 ml and 167.5 +/- 23.0 micrograms/gm in asthmatic cases and 65.9 +/- 11.7 micrograms/100 ml and 164.8 +/- 23.6 micrograms/gm in those with atopic dermatitis. These levels were significantly (p less than 0.001) decreased in comparison to the control values (88.4 +/- 11.0 micrograms/100 ml and 194.5 +/- 18.6 micrograms/gm). On the other hand, a significant (p less than 0.001) increase in serum and hairs copper was demonstrated in both allergic groups compared to the controls. Mean copper values were respectively 79.5 +/- 8.06 micrograms/100 ml and 18.7 +/- 1.9 micrograms/gm in the asthmatic cases and 81.4 +/- 8.4 micrograms/100 ml and 17.8 +/- 2.08 micrograms/gm in cases with atopic dermatitis. The control mean concentrations were 67.95 +/- 6.37 micrograms/100 ml and 14.5 +/- 2.53 micrograms/gm respectively. Significant (p less than 0.001) higher levels of serum ceruloplasmin were observed in the allergic patients compared to the controls and were correlated with the hypercupremia. The results were discussed and a good dietetic intake of high biological value protein and zinc supplement was recommended to these patients in order to correct their disturbances especially the hypozincemia which could lead to exaggeration of their allergic conditions. The field of trace elements metabolism has grown rapidly over the past few years, particularly after the development of novel techniques as the atomic absorption spectrophotometry which had allowed the reliable measurements of several trace elements in tissues and so had opened a new field for many researches (Henkin, 1976). Zinc and copper are involved in cell and tissue growth. Zinc plays an important role in DNA and protein synthesis and is intimately involved with copper as cofactors in several important enzyme systems. The effects of many pathological conditions as congestive heart failure, pneumonia, rheumatic heart diseases, bronchitis, recurrent infection, hemolytic anemia, psoriasis, and malnutrition on the levels of serum zinc, copper, and other trace elements have been of interest to investigators for a number of years (Sinha and Gabrieli, 1970; David et al., 1984).(ABSTRACT TRUNCATED AT 400 WORDS)

To evaluate the effect of copper deficiency on growth in humans a prospective case-control study was performed in Chile on a group of 11 infants identified as Cu deficient based on low plasma Cu (70 mcg/dL (11.0 mcmol/L) and low ceruloplasmin (200 mg/L). Growth was evaluated with anthropometric indices 1 month before and 1 month after onset of Cu supplementation of 80 mcg x 1/kg x 1/d. Plasma Cu and ceruloplasmin rose significantly after 1 month of supplementation. Weight-for-age and weight-for-length indices increased significantly after supplementation only in the Cu-deficient group. Daily energy intake was significantly higher in the Cu-deficient group after supplementation than it was in the control group. Daily weight gain after supplementation increased significantly in the Cu-deficient group and the value for daily weight gain after supplementation was significantly higher than that of the control group for the equivalent amount of time. Cu supplementation improves the growth of Cu-deficient infants recovering from malnutrition.

A monkey model has been set up for protein calorie malnutrition and calcium deficiency. Oral exposure of 5ppm Cd/kg body wt./day for 24 weeks led to increased excretion of Cd, metallothionein (MT) and zinc. Rehabilitation of PCM monkeys for one year resulted in gradual reduction and finally complete disappearance of urinary metallothionein. During Cd exposure, the accumulation of Cd and induction of MT was significantly higher in liver, kidney and intestine. MT was also induced in heart, lung and testis of Cd exposed PCM and calcium deficient monkeys. Metallothionein from liver has been resolved into three isoforms, viz MTa, MTb and MTc on DEAE-Sephadex A 25 ion exchange column. MTc is the major isoform in Cd-treated, normal and protein calorie malnourished monkeys whereas MTb is the major isoprotein in the cadmium treated calcium deficient monkeys. The iso-metallothioneins varied in their metal composition in the nutritional stress conditions and showed different capacities to reactivate apo-enzymes viz. alkaline phosphatase, ceruloplasmin, superoxide dismutase and glutathione peroxidase. Thus, metallothionein plays a key role in metal metabolism during cadmium toxicity under nutritional stress conditions.

Deficiency of serum ceruloplasmin is a characteristic biochemical abnormality of Wilson's disease, although the mechanism of this finding is unknown. Ceruloplasmin messenger RNA (mRNA) levels were therefore examined in five patients with Wilson's disease and five controls with other types of hepatic disease. Northern and dot blot hybridizations showed that detectable ceruloplasmin mRNA was present in all of the patients with Wilson's disease, including one patient with no detectable serum ceruloplasmin. However, the ceruloplasmin mRNA levels in the Wilson's disease patients were only 33% that of controls (P less than 0.001). In contrast, albumin mRNA levels in the Wilson's disease patients averaged 161% that of controls. In an attempt to better delineate the level of gene expression responsible for this decrease in ceruloplasmin mRNA, the nuclear run-on assay was used to analyze transcriptional rates. The amount of ceruloplasmin gene transcription in four Wilson's patients was decreased to 44% that of three controls. These results indicate that the diminished serum ceruloplasmin levels in patients with Wilson's disease are due at least in part to a decrease in ceruloplasmin gene transcription.

Red cell superoxide dismutase (SOD) activity was evaluated as a biochemical index of copper nutrition in a double-blind study of 17 infants recovering from malnutrition and receiving marginal copper intakes. Children were paired on admission by sex, birth weight, nutritional status and antecedents of diarrhea and breast feeding. Nine served as controls receiving a copper sulfate supplement (80 micrograms/kg daily for 120 d; eight received a placebo and were supplemented only if plasma copper levels dropped below 90 micrograms/dl or on d 90 for at least 30 d. After copper supplementation there was a significant rise (paired t-test; P less than 0.05) in plasma copper (96 vs. 165 micrograms/dl); ceruloplasmin (33 vs. 50 mg/dl) and SOD (1073 vs. 1371 U/g Hb). After supplementation these values were similar to those of the controls. SOD was correlated with plasma copper (r = 0.78; P less than 0.001) and not with weight-for-age or weight-for-length. Addition of copper in vitro did not modify the SOD activity. Red cell SOD is a good marker of copper nutrition in humans and correlates well with plasma copper.
