From 1960 to 1984, 27 cases of total colonic aganglionosis were treated at the Sick Children's Hospital in Paris; in 19 cases there was ileal involvement, 16 of them extending more than 15 cm above the ileocecal valve. Five had a family history of Hirschsprung's disease. Nine infants died without having had definitive surgery, because of delayed diagnosis, or intractable malabsorption in extensive ileal aganglionosis. Two cases were diagnosed only at the ages of 6 and 13 years. Eleven children had Martin's modification of the Duhamel operation, the oldest of these being now 13 years old; and one girl aged 13 underwent a Swenson operation with ileoanal anastomosis, and one child has had a Kimura procedure. Four infants still have a diverting ileostomy. One out of the 14 operated children died 3 years after operation with fulminating enterocolitis. Late surgical nutritional results are analyzed with regard to the length of the side-to-side ileocolorectal anastomosis, and to the size of the ileorectal anastomosis, on which adequate pouch emptying depends. The essential problem in total colonic aganglionosis is not the surgical management of the condition, but rather its prompt diagnosis and the handling of the neonatal intestinal obstruction.

Two homosexual Danish men with the acquired immunodeficiency syndrome (AIDS) contracted cryptosporidium enterocolitis. One patient died in another opportunistic infection, the other developed severe chronic enterocolitis with malabsorption. The cryptosporidia escape detection on routine stool examination, but are easily demonstrated by a modified Ziehl-Neelsen stain. It is suggested that this procedure should be applied when persons from AIDS high risk groups or patients with other forms of immunological incompetence develop prolonged diarrhoea.

Absorption and assimilation of some of fatty acids and fatty acid composition of platelet lipids and red cell stroma were studied in 75 patients suffering from the malabsorption syndrome. The patients were distributed in 4 groups in terms of the disease severity. The patients subjected to an extensive resection of the small intestine and those with stage III enterocolitis manifested malabsorption, because of significant steatorrhea, of food polyunsaturated fatty acids, particularly of linoleic acid. This led to the deranged formation of lipid structures of biomembranes, which is evidenced by the magnitudes of the essential metabolism ratio (EMR). The disease severity was in good agreement with the intensity of steatorrhea and the decrease of EMR. The data obtained form the basis for recommendations on an adequate fatty acid composition of the diet designed for patients with the malabsorption syndrome. It is thus recommended that the diet should include fat products rich in fatty acids with a short- and medium-size carbon chain, oils rich in oleic acid, and be supplemented as well with polyunsaturated fatty acids in the concentrated form ("essentiale" preparations).

In 30 patients with dyspepsia caused by dysbacteriosis of the gastrointestinal tract the authors administered the preparation Lactobacillus acidophilus (Rossel Co. Canada)--1. capsule with 2 billion live bacteria, in the morning after breakfast. The patients were divided into four groups: maldigestion, malabsorption, radiation enterocolitis and administration of antibiotics. The patients recorded themselves their subjective symptoms: pain, pressure, bloating, flatulence and appetite, and as to objective symptoms, the number and consistency of bowel movements, changes of body weight. The most rapid effect was achieved in dysbioses after antibiotics--within 3-4 days normalization occurred which persisted even after discontinuation of the drug. In maldigestion after one week bloating, flatulence, abdominal pain and pressure in the epigastrium was milder, and within two weeks the condition improved further. An excellent effect was achieved in radiation enterocolitis. In patients with lactose intolerance the tolerance of dairy products improved. No side-effects were observed, the preparation was very well tolerated; the mean body weight increment was 0.75 kg in three weeks. The preparation proved a new useful probiotic which is highly effective in dyspepsias caused by dysbiosis of the intestinal microflora.

Nongranulomatous chronic idiopathic enterocolitis is characterized by sudden onset of severe watery diarrhea, malabsorption, exudative enteropathy, frequent appearance of shallow ulcerations, and variable degrees of villus atrophy. In the absence of infectious and pharmacologic causes, the presence of a predominantly acute inflammatory infiltrate limited to the lamina propria establishes the diagnosis. No underlying disease appears during prolonged follow-up. The etiology remains unknown. The disease is generally corticosteroid-responsive; low-dose maintenance therapy is frequently required. The long-term prognosis is guarded. Three of 11 patients died of opportunistic infections or resistance to therapy.

During the period from 1974 to June 2000 we used the straight ileo-anal Soave pull-through to treat 42 patients (24 affected by total colonic aganglionosis [TCA], 10 with ulcerative colitis and 8 with familial polyposis). The aim of this paper is to show that this operation, associated with total colectomy, is highly recommended, causing a lower number of complications when compared to the various "reservoir" techniques. The mean age of the 24 patients with TCA at the time of the pull-through was 2.8 years; in the ulcerative colitis group, it was 14.3 years and in the familial polyposis group 27.2 years. We always used an ileo-anal deferred anastomosis and never performed temporary loop-diverting ileostomy at the time of the pull-through. In the TCA patients we had no immediate or long-term serious post-operative complications: ileal adaptation, after a frequency of 10 - 12 liquid stools a day, showed a gradual, constant and in some cases amazing improvement in all children. Two years after surgery, the mean stool frequency was 3.6 per 24 hours with no significant differences between the 3 main groups; only 4 children still presented with occasional soiling. After pull-through, all children showed normal growth curves in the long term. There was no malabsorption, no serious electrolyte imbalance, no perianal excoriation, no strictures or intestinal obstruction; their quality of life was considered more than satisfactory by the children's families. We have no direct experience with the various ileal "reservoir" techniques for ulcerative colitis and ileal polyposis nor with colon-sparing operations for TCA; as reported in the literature, all these surgical procedures seem to have a higher number of complications such as pelvic sepsis, pouchitis, enterocolitis, etc. compared with our series; we therefore confirm that total colectomy with the straight ileo-anal Soave pull-through is our treatment of choice, as it is simpler to perform and has fewer short- and long-term complications.

Celiac sprue is a disease in which there is malabsorption of nutrients by that portion of the small intestine which is damaged, a characteristic though not specific lesion of the small intestinal mucosa and prompt clinical improvement following withdrawal of certain cereal grains from the diet. We present a 41 years old patient with a history of diarrhea, treated as enterocolitis for several years, in which the gluten-free diet brought a clinical improvement.

Multiple cases with various types of pediatric malabsorption syndromes were evaluated. The clinical manifestations, laboratory findings, pathophysiology, and histopathological descriptions of each patient were analyzed in an effort to clear the pathogenesis of the malabsorption syndromes and the treatments were undertaken. The cases studied, included one patient with cystic fibrosis, two with lactose intolerance with lactosuria (Durand type), one with primary intestinal lymphangiectasia, two with familial hypobetalipoproteinemia, one with Hartnup disease, one with congenital chroride diarrhea, one with acrodermatitis enteropathica, one with intestinal nodular lymphoid hyperplasia (NLH), five with intractable diarrhea of early infancy and four with glycogenosis type Ia. Each case description and outcome is described below: 1. A 15-year-old Japanese boy with cystic fibrosis presented with severe symptoms, including pancreatic insufficiency, bronchiectasis, pneumothorax and hemoptysis. His prognosis was poor. Analysis of the CFTR genes of this patient revealed a homozygous large deletion from intron 16 to 17b. 2. In the sibling case of Durand type lactose intolerance, the subjects'disaccaridase activity of the small bowel, including lactase, were within normal limits. The results of per oral and per intraduodenal lactose tolerance tests confirmed lactosuria in both. These observations suggested, not only an abnormal gastric condition, but also duodenal and intestinal mucosal abnormal permeability of lactose. 3. In the case of primary intestinal lymphangiectasia, the subject had a lymphedematous right arm and hand, a grossly coarsened mucosal pattern of the upper gastrointestinal tract (identified via radiologic examination) and the presence of lymphangiectasia (confirmed via duodenal mucosal biopsy). The major laboratory findings were hypoalbuminemia, decreased immunoglobulin levels and lymphopenia resulting from loss of lymph fluid and protein into the gastro-intestinal tract. 4. In two cases of heterozygous familial hypobetalipoproteinemia, serum total cholesterol and betalipoprotein levels were very low. The subjects presented with symptoms and signs of acanthocytosis and fat malabsorption. Further, one subject had neurological abnormalities such as mental retardation and severe convulsions. Treatment with MCT formula diet corrected the lipid malabsorption. 5. A 5-year-old girl presented with pellagra-like rashes, mental retardation and cerebellar ataxia. An oral tryptophan (Trp) and dipeptide (Trp-Phe) loading test were conducted and the renal clearance of amino acids was also evaluated in this patient and in controls. Following the oral Trp loading test, plasma levels of Trp indicated a lower peak in the case, reaching a maximum at 60 minutes. On the other hand, the oral dipeptide (Trp-Phe) loading test in the Hartnup patient showed the peak Trp plasma level was the same as the control subjects. The renal clearance of neutral amino acids in this case increased to levels 5 to 35 times normal. 6. In the case of congenital chloride diarrhea, the subject had secondary lactose intolerance, dehydration, hyponatremia, hypokalemia, hypochloremia, hyperreninemia and metabolic alkalosis. The chloride content of her fecal fluid was very high. The concentrations were 89-103 mEq/l. In contrast, her urine was chloride-free. The subject's growth and development improved after treatment with lactose free formura and oral replacement of the fecal loses of water, NaCl and KCl. Unfortunately, the patient died of a small bowel intussusception. The kidney histopathological finding was juxtaglomerular hyperplasia by a necropsy. 7. In the case of acrodermatitis enteropathica, the subject had characteristic skin lesions, low serum zinc levels and ALPase activity. An oral ZnSO4 loading test and intestinal mucosal histology by a peroral biopsy were conducted. The serum zinc peak level was 2 hours after the oral ZnSO4 loading test. Infant formula alone could not maintain normal serum zinc ranges. Light microscopic studies of the intestinal villous architecture showed a normal pattern. However, ultrastructual examination of several epithelial cells revealed numerous intracellular vesicles. After zinc therapy, these changes were decreased. The lesions were postulated as the secondary result of zinc deficiency. 8. A 12-year-old girl presented with hypogammaglobulinemia, recurrent infections, chronic diarrhea and intestinal NLH. A barium meal and follow-through examination showed multiple nodules throughout the stomach and intestine. The nodules, all uniform in size, were 2 mm diameter. The barium enema did not show NLH in the colon. Mucosal biopsy of the stomach and jejunum revealed the typical histology of NLH in the lamina propria. Also, achlorhydria was present in this patient and her serum gastrin levels were very high; 315-775 pg/ml. 9. In 4 cases of intractable diarrhea in early infancy (by Avery G B), a jejunal biopsy showed shortening villi and nonspecific enterocolitis. Some patients were found with only low lactase or low lactase and sucrase levels. An electron microscope analysis of the small bowel in 2 cases showed alterations: increased pinocytosis in microvillus membranes and lysosomes by endocytosis of undigested macromolecular substances. I postulated that the stated evidence was causative of this clinical profile. 10. I frequently observed diarrhea as a clinical manifestation in glycogenosis type Ia and lipid malabsorption in one case. The light and electron photomicrographs showed intestinal absorption cells with the glycogen deposits in the inferior devision of nuclei.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is chronic in nature and is characterized by abdominal pain, diarrhea, bleeding, and malabsorption. It is considered a complex multigenic and multifactorial disorder that results from disturbed interactions between the immune system and commensal bacteria of the gut. Recent work has demonstrated that IBD with an early-onset within the first months of life can be monogenic: mutations in IL-10 or its receptor lead to a loss of IL-10 function and cause severe intractable enterocolitis in infants and small children. Both IL-10 and IL-10 receptor deficiency can be successfully treated by hematopoietic stem cell transplantation.

Inflammatory bowel disease (IBD) is a chronic inflammatory disease characterized by abdominal pain, bloody diarrhoea, and malabsorption leading to weight loss. It is considered the result of inadequate control of an excessive reaction of the immune system to the resident flora of the gut. Like other primary immunodeficiencies, IL-10 and IL-10 receptor (IL10R) deficiency present with IBD and demonstrate the sensitivity of the intestine to any changes of the immune system. Both IL-10 and IL10R deficiency cause severe early-onset enterocolitis and can be successfully treated by hematopoietic stem cell transplantation (HSCT).
