A 47-year-old man had diarrhea in 1965. Four years later, malabsorption syndrome was diagnosed and the patient was found to have mild lymphocytosis. Abdominal lymphoma was suspected, but exploratory laparotomy was normal except for partial villous atrophy of small intestine and slightly enlarged mesenteric lymphnodes which were normal microscopically. In vitro lymphocyte blastformation with phytohemagglutinin was depressed markedly throughout the course and the result predicted the developement of malignancy of the lymphocytic system. Infection of Isospora belli was found thereafter, and sulfamethoxazole was quite effective for diarrhea. In August, 1974, he noticed cervical lymphadenopathy for the first time and it was diagnosed as undifferentiated type of malignant lymphoma. He died in December, 1974. In this case diarrhea was most probably caused by the intestinal infection of Isospora belli without obvious lymphoma. The symptom was swept away by peroral sulfamethoxazole. In this patient coccidiosis was presumably induced and prolonged by suppression of cellular immunity which might have already begun to progress at the onset of diarrhea.

An elemental diet containing predigested protein, a high content of predigested fat and carhobydrate, trace elements and vitamins, was administered as the only form of nutrition to 9 adult patients with chlonic, ileal and pancreatic fistulae, Crohn's disease, ulcerative colitis, malabsorption states and abdominal lymphoma, and to 4 children with protracted diarrhoea. The diet was administered orally through a nasogastric tube for 1 - 8 weeks. Two patients were treated on an outpatient basis. There was considrable clinical improvement in 6 adults and in 3 children. Two adults and 1 child did not respond and 1 adult did not co-operate. The results justify the use of this elemental diet in carefully selected patients under strict medical supervision.

A case of extensive primary lymphocytic lymphoma (lymphosarcoma) of the gastrointestinal tract is reported. At the time of presentation the patient had diffuse involvement of the gastrointestinal tract from the stomach to the ano-rectal junction. Malabsorption was present. Pre-treatment immunologic studies showed elevated serum IgA and IgG, but impaired humoral and cellular immunity. Death occurred 13 months after diagnosis.

Five cases of primary intestinal lymphoma are described. The main clinical features included abdominal pain, diarrhea, and marked weight loss, together with radiologic and some laboratory findings suggestive of malabsorption. Laparatomy perfomed in four cases revealed dilatation of the small intestine, with mesenteric node enlargement. In these four instances there was a definite histologic evidence of malignant lymphoma, either initially or later in the course of the disease. A characteristic feature here was the diffuse infiltration of the intestinal mucosa with plasma cells, which in the deeper layers became progressively atypical and were mixed with histiocytes and giant cells. A similar infiltrate was seen in the mesenteric nodes. Immunoelectrophoresis showed the pattern of IgA heavy chain disease. It is suggested that the latter is a variant of primary intestinal lymphoma and not a separate disease entity.

A study of the absorptive function of the small intestine in chidlhood malignant lymphomas was carried out at the Cancer Institute of Cairo University. The study comprised twenty-five children, with stage III or IV lymphoma. A complete lymphoma work-up was performed for each patient, comprising clinical, pathological, haematological, biochemical and roentgenological assessments. Evaluation of small intestinal function was done by means of mucosal biopsy, small bowel motor meal, xylose excretion test, and estimation of faecal fat excretion. These tests revealed evidence of malabsorption in 69% of the patients. The study provides a better understanding of childhood malignant lymphomas in Egypt, and shows that malabsorption may be more common in the disease than has been previously suspected.

Iron malabsorption compounded the anemia in a patient with diffuse large cell lymphoma involving the small intestine. Both upper gastrointestinal series with small bowel follow-through and computerized tomographic scan demonstrated lymphomatous involvement of the duodenum and proximal jejunum by a retroperitoneal mass. An oral iron-loading absorption test was consistent with malabsorption of iron. After two cycles of systemic chemotherapy, the retroperitoneal mass resolved and the iron loading test normalized.

Twenty-seven cases of primary peripheral T-cell lymphomas of the intestine (PTLI) were investigated. Seven patients had histories of malabsorption. The most frequent symptoms at presentation were weight loss, abdominal pain, and acute abdomen. The jejunum was the most common site of lymphoma and multifocal disease was found in 72% of the cases. Twenty-two patients (92%) presented with localized disease confined to the intestine and abdominal lymph nodes, only two patients had generalized disease. According to the pattern of lymphoma infiltration and the morphology of the uninvolved small intestinal mucosa, 21 cases were separated histologically into three categories; 1) enteropathy-associated T-cell lymphoma (EATCL, n = 9) showing predominant intramucosal lymphoma spread and villous atrophy of uninvolved mucosa with high density of intraepithelial lymphocytes (IEL), 2) EATCL-like lymphoma without enteropathy (EATCL-LLWE, n = 5) but with an infiltration pattern similar to EATCL, and 3) T-cell lymphoma without features of EATCL (Non-EATCL, n = 7). Distinctive features of EATCL were the high incidence of malabsorption states, multifocal intestinal disease in all cases, and the high frequency of intestinal recurrences. On frozen sections four of eight PTLI showed the phenotype CD3+ CD4- CD8- HML-1+, which is also expressed on a small subset of normal IEL. The morphologic and immunomorphologic findings suggest that the majority of PTLI is derived from mucosal T lymphocytes. This derivation may be responsible for certain biologic features, such as the preferential spread to and relapse of PTLI at small intestinal sites.

The coeliac disease (CD) or gluten-sensitive enteropathy (GSE) is a permanent intolerance to wheat gliadin and to correlated proteins inducing malabsorption and typical damages of the jejunal mucosa (total or subtotal villous atrophy = SVA) in genetically-predisposed individuals ("DQW2"). A large amount of research has been devoted to CD pathogenesis: the most recent studies, thanks to sophisticated and experimental methods, support the pathogenetic immunological theory and the one of direct cytotoxicity. The correct diagnostic procedure for CD, established in 1970 by the European Society for Pediatric Gastroenterology and Nutrition (ESPGAN), suggested three small bowel mucosal biopsies. In the last years, because of the difficulties of such a practice, the necessity of non-invasive diagnostic approaches has developed; such approaches have been verified in absorption tests (one-hour blood xylose, intestinal permeability methods) and in immunogenetic tests (antibodies antigliadin, anti-reticulin, anti-endomysium, anti 90 KD glycoprotein, anti-human jejunum, HLA I/II antigens). The specific MHC antigens establish CD's incidence in several population and in particular situations, as in first-degree relatives and in diseases associated with CD (dermatitis herpetiformis (DH), insulin dependent diabetes mellitus (IDDM) and other auto-immune syndromes). The specific serum antibodies singly used as first level screening if estimated in combination with absorption tests, reach the highest levels of specificity and sensibility in CD diagnosis. It's anyway fundamental the comparison with at least a typical CD histological feature, caused by a challenge with a sufficient gluten to be carried in dubious cases and in non high auxological risk age (ESPGAN 1989). Adolescence is a period of frequent non compliance with a gluten-free diet and of particular psychological and physical problems: the apparent "gluten insensitivity", typical of teen-agers and adults, recalls the definitions of silent CD and latent CD (iceberg like). In the first case the jejunal mucosa is abnormal and the symptomatology isn't evident. In latent CD, genetically restricted, the mucosa is normal but there are minimal markers of inappropriate immunity to gliadin (at intestinal humoral immunity level) and a possible worsening of histological lesions to the third stage under environmental stimuli. This represents a two-stage model CD. That's why CD is still under-evaluated despite recent statistics reporting an increasing incidence (late and atypical forms). Prevalence rates between 1:300 and 1:4,000 and more are quoted in literature. The necessity of a strict gluten-free diet is confirmed by the evident frequency of lymphoma and by the increased risk of malignancy in untreated CD.(ABSTRACT TRUNCATED AT 400 WORDS)

Antibodies to gliadin IgA (IgA-AGA) were detected by enzyme-linked-immunosorbent-technique (ELISA) in 30 healthy controls, 20 coeliac patients and 25 patients with non coeliac malabsorption. All the controls had levels of IgA-AGA in the normal range (25AV). Three of the 25 patients with non coeliac malabsorption presented high titres of IgA-AGA. Thirty six determinations of IgA-AGA were made on the coeliac patients. All but one of the determinations made during the symptomatic phase of the disease were 25AV. The highest titres corresponded either to untreated patients or patients with complications (cirrhosis, lymphoma). In our study the sensitivity and the specificity of the test for symptomatic patients were 94.4% and 94.5% respectively.

A patient with disseminated gastrointestinal sarcoidosis and non-Hodgkin's malignant lymphoma developed diarrhea and polyadenopathy. Laboratory analysis revealed the presence of protein-losing enteropathy without biological signs of malabsorption. Gastrointestinal biopsy specimens showed numerous sarcoidosis nodules without neoplastic proliferation in the stomach, small intestine, and rectum. The patient's course was favorable after treatment with prednisone and chlorambucil. Disseminated gastrointestinal sarcoidosis may be a previously unidentified cause of protein-losing enteropathy.
