Antibodies of various immunoglobulin classes against cow's milk proteins were studied in infants and children with cow's milk protein intolerance, gluten-sensitive enteropathy and acute gastroenteritis. Their IgE, IgG, IgM and IgA antibody levels determined with the enzyme-linked immunosorbent assay (ELISA) and the IgE antibodies also determined with RAST, were compared with reference groups of children and adults. IgE, IgT or IgA antibodies against unseparated cow's milk proteins, alpha-lactalbumin, beta-lactoglobulin, alpha-casein and beta-casein were present in many of the studied samples, but did not discriminate between the individuals with and without intolerance symptoms. As a group, the infants with late reactions to cow's milk showed increased levels of IgE and IgG antibodies detected with the ELISA, while patients with gluten-sensitive enteropathy had significantly increased levels of IgG and IgA antibodies of cow's milk proteins compared to the reference group. By combining the findings of antibody increases in various immunoglobulin classes, an individual discrimination could be reached. Thus, 8 of 9 of the patients with late reactions to cow's milk had increased levels of IgE or IgG + IgA antibodies as compared to 3 of 22 in the reference group. Serodiagnosis with the ELISA may, therefore, be of some use in patients with a suspicion of cow's milk protein intolerance.

Tropical enteropathy, which may be related to tropical sprue, has been described in many developing countries including parts of Africa. The jejunal changes of enteropathy are seen in Rhodesians of all social and racial categories. Xylose excretion, however, is related to socioeconomic status, but not race. Upper socioeconomic Africans and Europeans excrete significantly more xylose than lower socioeconomic Africans. Vitamin B12 and fat absorption are normal, suggesting predominant involvement of the proximal small intestine. Tropical enteropathy in Rhodesia is similar to that seen in Nigeria but is associated with less malabsorption than is found in the Caribbean, the Indian subcontinent, and South East Asia. The possible aetiological factors are discussed. It is postulated that the lighter exposure of upper class Africans and Europeans to repeated gastrointestinal infections may accound for their superior xylose absorption compared with Africans of low socioeconomic circumstances. It is further suggested that the milder enteropathy seen in Africa may be explained by a lower prevalence of acute gastroenteritis than in experienced elsewhere in the tropics.

Intestinal transit times in children less than 3 years old with gastroenteritis were measured using carmine suspension and radioopaque pellets. Carmine transit times were short as expected in the acute illness, and lengthened on recovery to the values found in children without diarrhoea. Pellet transit times of the sick children were the same as those of controls without bowel disease. Solid markers may thus be misleading in acute diarrhoeal illness of childhood. Possible mechanisms are discussed.

A 58 year old Chinese male, one week after arriving in Canada from Hong Kong, presented with acute abdominal pain and diarrhoea which was rapidly followed by Escherichia coli infection causing septicaemia and meningitis. His past history revealed bronchial asthma for 15 years treated with steroids. At laparotomy, 7 days after the onset of symptoms, he was found to have extensive haemorrhagic infarction of the small bowel and right colon. Examination of the fibrosed mesenteric vessels revealed numerous filariform larvae of Strongyloides stercoralis, within the walls, and in all layers of bowel wall. The role of the parasite in the production of obliterative arteritis in this fatal case of haemorrhagic enteropathy is discussed. Clinical strongyloidiasis, in uncomplicated cases, varies from mild to severe with gastroenteritis, nausea, colicky abdominal pain, electrolyte imbalance and symptoms of malabsorption syndrome (MARCIAL-ROJAS, 1971). In malnourished individuals and patients with debilitating infections, either newly acquired or asymptomatic latent infection with S. stercoralis can assume severe dimensions (BROWN and PERNA, 1958; HUGHTON and HORN, 1959). Similarly, in patients on steroid (CRUZ et al., 1966; WILLIS and MWOKOLO, 1966; NEEFE et al., 1973) and immunosuppressive therapy for lymphomatous diseases or deficient in immune response (ROGERS and NELSON, 1966; RIVERA et al., 1970), systemic strongyloidiasis is often fatal. The increased frequency of auto-infection in such patients with a breached immune barrier is, however, unclear. Further complications of this infection due to severe enterocolitis result in sepsis, bacteraemia and meningitis (BROWN and PERNA, 1958; HUGHTON and HORN, 1959). This paper presents a fatal case of S. stercoralis infection which illustrates an uncommon if not unique, mechanism in its production of haemorrhagic enteropathy leading to sepsis and death.

In a group of nine children with postenteritis enteropathy (i.e., persisting small-intestinal mucosal damage and failure-to-thrive after an acute episode of gastroenteritis), absorption capacities for vitamin B12 and folic acid were studied and compared with hematological status in peripheral blood. The fractional absorptions of vitamin B12 (FAB12) and folic acid (FAFol) were determined by means of a double-isotope technique employing a single-stool-sample test. The children were examined when growth retardation was maximal, and examinations were repeated during the late recovery period. In spite of considerable small-intestinal mucosal damage, only the absorption of vitamin B12 was markedly affected, while that of folic acid was almost intact. When growth retardation was maximal, FAB12 was below the normal age-correlated range in half of the children. FAB12 was also severely reduced in all longitudinally observed children when compared with the results obtained during the late recovery period (p less than 0.005). FAFol was below the normal range in one fourth of the children, but the reduction was modest and insignificant when compared with the results of repeated examinations during the late recovery period. A moderate iron deficiency was detected in half the children. High levels of plasma vitamin B12, folic acid, and erythrocyte folate were detected at both early and later examinations, indicating that these parameters were not affected by the reduced absorption capacities. However, if malabsorption and chronic diarrhea are combined with low dietary intake of vitamin B12, as is the case for many children in the Third World, depletion of vitamin B12 stores may result.

Ten patients, who developed postenteritis enteropathy with chronic diarrhoea, failure to thrive and small intestinal mucosal damage after an episode of acute gastroenteritis, were studied prospectively. All patients experienced severe growth retardation. Maximum deviation of height and weight from mean values of age-correlated normal children were -1.7 and -3.1 SD (median values), respectively, as compared to -0.1 and 0 SD before onset of the illness. One child died after 14 months of illness. The long-term outcome was satisfactory for the 9 surviving children. For these children, treatment with an elemental diet (in some cases supplemented initially with parenteral nutrition) and later a lactose-free diet lead to resolution of diarrhoea within periods ranging from 0.5 to 10 months. The phase of catch-up growth lasted from 4 to 36 months, resulting in final height and weight deviating -0.6 and -0.8 SD (median values), respectively, from normal mean values. Attempt to predict duration of diarrhoea or length of catch-up growth phase by means of age, weight before illness, characteristics of small intestinal biopsy or maximum deviation of height or weight were unsuccessful. The incidence of postenteritis enteropathy for children of North European ethnic origin was estimated to be 7.6/1,000,000 children below 7 years of age/year, corresponding to 1.2/1,000 children hospitalized for acute gastroenteritis.

Clinicians have only recently become aware that Cryptosporidium is a major human pathogen, causing a self-limited gastroenteritis in immunocompetent individuals and profound enteropathy in the immunocompromised. Among the immunologically intact, children appear more prone to clinically significant cryptosporidiosis than do adults. Diagnosis is most easily made by a specialized three-step stool examination, but mucosal biopsy may also be necessary to establish the diagnosis. Although no satisfactory antibiotic therapy exists today, cases of cryptosporidiosis in the community and hospital should be identified in order to contain human transmission. Only then can spread from immunocompetent individuals to immunodeficient individuals be avoided.

The pathology of the alimentary tracts of nine patients dying of Salmonella typhimurium infection is reviewed. Two patients had previous gastric operations, supporting previous reports that such patients are more susceptible to food poisoning. Four had no parietal (oxyntic) cells in the gastric mucosa, suggesting hypo- or anacidity. Only one had acute gastritis. None had acute enteritis, but in half of the patients, subtle histological changes suggested an 'enteropathy'. Acute diffuse colitis with abundant crypt abscesses, without stromal abscesses in the lamina propria, was the most constant finding and reparative features started very early, and occurred in later deaths. Under ideal circumstances this crypt abscess is readily distinguished from that of idiopathic ulcerative colitis, but can be confused with the crypt abscess of acute bacillary (sonne) dysentery. While the florid colonic changes may have settled in the late deaths, active inflammation is commonly present in the appendix mucosa on histology. The pathology of the alimentary tract in S typhimurium infection differs from that of S typhi and S paratyphi infections. There is little evidence of gastroenteritis, although subtle changes occur in the stomach and small intestine. The features are those of acute diffuse colitis with histological appendicitis, distinguishable from idiopathic ulcerative colitis.

Cryptosporidial oocysts were identified by modified Ziehl-Neelsen stain in the stools of seven (3.2%) of 213 children with acute or chronic diarrhoea and one (0.9%) of 112 controls. All children with cryptosporidia were immunocompetent. Four of the index cases had a short illness (3-14 days) with watery diarrhoea, vomiting (2), and abdominal pain (2). Two index cases had chronic diarrhoea for over four months and failure to thrive. Both had a small intestinal enteropathy; one had cryptosporidial oocysts in stool specimens two months apart and the other had cryptosporidial schizonts attached to the jejunal mucosa. One index case had a colitis of indeterminate cause. Four of the index cases had recently travelled abroad. There had been an outbreak of gastroenteritis in the family of one of the index cases, and three affected sisters and an asymptomatic brother had oocysts in their stools. Cryptosporidial infestation seems to be associated with acute gastroenteritis and sometimes with chronic diarrhoea and small bowel damage in immunocompetent children.

Dr. Grayson (February 21, p. 445) asks about changes in vital statistics of 3rd world populations as they develop. Of African populations, those in Johannesburg and other large South African cities, while still in transition, have now reached a relatively high level of sophistication. Their health pattern is likely to be that of other African countries as they prosper. The (IMR) infant mortality rate of blacks in Soweto, Johannesburg, is about 40/1000 live births, although nearer 30 in the regularly employed elite. This figure is similar to that for blacks in New York in 1965 and for class 5 persons in the United Kingdom. Small-town dwellers have higher IMRs and in rural areas the rates are higher still although they are decreasing everywhere. Family size is decreasing; in urban areas the average family has 3-4 children and the elite have 2-3. In Johannesburg during the 1960s, the birth rate was about 40/1000 and it is now 25. While the rate is higher in rural areas, it is falling. In the very young, gastroenteritis with or without malnutrition is still the leading cause of sickness and death in both urban and rural areas. Rates are however decreasing. Deficiency diseases, especially pellagra, remain a health problem in some areas. Tuberculosis still continues to be a major hazard although it is being dealt with. With the rise in socioeconomic status and associated changes in diet and lifestyle, obesity, especially in urban areas and especially among women, is becoming very prominent. Hypertension is more common and is the leading cause of natural death among urban dwellers. The toll from coronary heart disease and noninfective bowel disease remains inexplicably low, but diabetes is only somewhat less prevalent than it is among whites. Changes in cancar pattern and rates are slight; however, esophageal cancer in men and cervical cancer in women are the main causes of concern in the urban centers and some rural areas. Rising alcohol consumption is a major problem with its ramifications in pancreatic, liver, and heart problems. Cigarette smoking is now as common as among whites. Because of low rates for most degenerative diseases, blacks have, at middle age, a life expectancy exceeding that of whites. As sections of the 3rd world population prosper, the IMR decreases enormously as does family size. However, infections and malnutrition among the very young and tuberculosis in older groups remain important problems. Among adults, rises occur in some degenerative diseases but not in others, and diseases linked with hypertension and alcohol consumption have become formidably common, as they have in other developing and developed countries.
