A 78-year-old lady initially presented with painful hips, low back pain, lethargy and weight loss. She had a past history of osteomalacia. Investigations revealed evidence of malabsorption and jejunal biopsy revealed sub-total villous atrophy in keeping with coeliac disease. Peripheral blood film was within normal limits. She responded well clinically to a gluten-free diet and calcium and vitamin D supplementation. Four years after the initial diagnosis she presented acutely with vomiting, pleuritic chest pain, pyrexia and bronchospasm. Blood cultures confirmed the presence of Streptococcus pneumoniae and she was treated appropriately with ampicillin. Despite this she died shortly after admission. It is recognized that blood film examination alone cannot exclude hyposplenism complicating coeliac disease and it is presumed that this was the reason for the development of fatal pneumococcal septicaemia in this patient. Prophylactic vaccination may be appropriate in hyposplenism secondary to coeliac disease.

Immunoproliferative small intestinal disease (IPSID), a proliferative disorder affecting the intestinal immune system, has only been reported sporadically in India. Fifteen patients with malabsorption syndrome who were diagnosed to have IPSID were included in this study. Mucosal biopsies from all patients, full thickness surgical biopsies from 10 and autopsy material from four patients were examined by light microscopy and immunohistochemistry. The patients were predominantly young (aged 16-36 years) and male (13 of 15). Diarrhoea, weight loss, vomiting and abdominal pain were the major symptoms. The upper small bowel was involved in all cases. Involvement of large bowel was detected antemortem in three patients, but was found in all autopsied patients. Involvement of the stomach was noted in one patient at autopsy. Mesenteric lymph nodes were involved in all patients who underwent laparotomy. The plasmacytic infiltrate was uniformly positive for alpha-heavy chain, and either negative for light chain production or showed monotypic light chain production. Some of the blasts were also positive for alpha-heavy chain. Three patients died before therapy could be commenced. One patient with stage A disease is alive and clinically free of disease at 7 years. Of the remainder, there have been four long-term survivors with chemotherapy. Immunoproliferative small intestinal disease occurs in southern India and has characteristics similar to that in other parts of the world. Early diagnosis may improve outcome in this disease.

Rifampin is the cornerstone of short-course chemotherapy for the treatment of tuberculosis (TB). Rifampin monoresistance (RMR) is less common than resistance to isoniazid alone or in combination with other antituberculous medications. We conducted a retrospective case-control study to identify risk factors for RMR-TB. Complete records for 21 of a total of 26 RMR patients from 1990 to 1997 were available for review, and were compared with those of 48 patients with drug-susceptible TB, controlling for year of diagnosis. Cases more frequently had a history of TB than did controls (61% versus 22%, p < 0.01), and were more often human immunodeficiency virus (HIV) positive (81% versus 46%, p = 0.02). With control for HIV status, cases were more likely to have extrapulmonary involvement (47.6% versus 11.6%, p = 0.05). Four cases (19%) and one control (2. 1%) died (p = 0.02) during hospitalization. Cases more often had a history of incarceration (71.4% versus 37.5%, p = 0.09). Among the 13 cases with a history of TB, five had evidence of malabsorption (vomiting and/or diarrhea), versus none of the 11 controls with prior TB. These data support the hypothesis that RMR is seen primarily in individuals with a history of TB and who are HIV positive. Cases were frequently noncompliant with previous treatment for TB, had a history of incarceration, and had poor outcomes.

Protein-energy malnutrition is an inevitable consequence of chronic liver disease, particularly in the developing infant. Severe malnutrition with loss of fat stores and muscle wasting affects between 60% and 80% of infants with liver disease (Beath, 1993a; Holt et al, 1997). Reduced energy intake secondary to anorexia, vomiting and fat malabsorption, in association with a disordered metabolism of carbohydrate and protein, increased energy requirements and vitamin and mineral deficiencies, contributes towards growth failure. Reversal of malnutrition is one of the key aims of liver transplantation and is achieved in the majority of long-term survivors. The aetiology of persistent growth failure post-transplantation is multifactorial and is related to pre-operative malnutrition, glucocorticoid administration, feeding problems and post-operative complications. Strategies to prevent pre- and post-transplant growth failure include early referral for liver transplantation and a multidisciplinary approach to nutritional support, which may increase survival and improve the quality of life and outcome of liver transplantation.

Coeliac disease is a gluten-sensitive enteropathy which results in a permanent malabsorption of nutrients in that portion of the small intestine (the jejunum) that is damaged. A genetic, inheritable disease, it is directly related to ingestion of certain wheat proteins especially found in rye secalins, barley hordeins and, in a much lower amount, oat avenins. A fundamental role in the pathological response is played by grain prolamins (gliadins). The actual damage to intestinal mucosa is almost certainly mediated by the immune system but its mechanism has not been so far clarified. Coeliac disease incidence rate is ever increasing among children and adolescents and it is rather frequently reported as relapsing in the third and fourth decade. The most distressing problems of malabsorption syndrome are diarrhea, weight loss, meteorism, abdominal pain, vomiting and asthenia; nonetheless, not all patients report symptoms. Both diagnosis and differential diagnosis--intestinal lymphoma, refractory sprue--prove difficult: a diagnosis of gluten intolerance can be made through careful consideration of a series of laboratory findings which are being improved by researchers in order to avoid delays for patients with probable gluten-sensitive enteropathy with non-specific symptoms. Although there may be many clinical signs and laboratory tests indicating probable malabsorption, the likely gold standard of diagnosing coeliac disease remains to be the jejunal biopsy.

High oral intake of cadmium via food or drink in a single dose by humans gives rise to vomiting, abdominal pain, and diarrhea. Concentrations of cadmium in drinks giving rise to such symptoms have been 16 mg/liter and higher corresponding to doses of 3 mg and higher. Longer term intakes of food (rice) with concentrations around 1 mg/kg corresponding to daily intakes of 600 micrograms have given rise to some less pronounced symptoms including signs of malabsorption. Reproductive and developmental effects have been observed in animal experiments at oral and other exposures. The present provisional tolerable weekly intake (PTWI) for Cd is 500 micrograms (a weekly intake of 7 micrograms/kg body wt), corresponding to a daily intake of 70 micrograms or 1 microgram per kg body wt. Recent data demonstrating renal dysfunction in humans at even lower lifelong oral exposures indicate that the PTWI needs to be lowered in the future. An estimated lowest-observed-adverse-effect level (LOAEL) for symptoms from the gastrointestinal tract in humans after intake of a single oral dose is 43 micrograms/kg body wt. If a safety factor of 3-10 is used based on LOAEL, a tolerable single dose would be 0.3-1 mg (4 to 14 micrograms/kg body wt). For longer time exposures (months-a few years) daily intakes of 200 micrograms (3 micrograms/kg body wt) may be tolerated without obvious gastrointestinal symptoms or signs. At present, there is no convincing human evidence that such doses can cause reproductive or developmental effects, but since such effects have been reported in animals, it may be advisable not to exceed a daily intake of 1 microgram/kg body wt for such potentially sensitive subsections of the population as children and women who are pregnant or lactating. Any excursions above the PTWI need to be compensated for by a corresponding period with intake below the PTWI in order for the cumulative dose to be low enough to avoid the long-term effects of cadmium on the kidney.

Four cases with Capillaria philippinensis have been reported from Egypt during 1989-1992. The authors report here four other cases of severe diarrhoea caused by this parasite. A male and three female patients aged 12-45 years presented with severe diarrhoea of 1-7 months duration associated with vomiting and central abdominal colics. Stools were yellowish or greenish and voluminous. Anorexia was profound with loss of weight. Bilateral painless ankle oedema developed early in the course of the disease and two cases had ascites and bilateral pleural effusion at presentation. There was hyponatraemia, hypocalcaemia and marked hypokalaemia and hypoalbulinaemia. Small bowel series showed a rapid transit time in 3 cases and malabsorption pattern in one. Duodenal biopsies showed non-specific chronic inflammation while jejunal biopsies from one case revealed grade II villous atrophy with moderate cellular infiltration of lamina propria. The infection was diagnosed by finding the eggs, larvae and adult worms of C. philippinensis in stool. Patients were treated with mebendazole 400 mg/day in two divided doses for 28 days in addition to high protein diet and correction of electrolyte disturbance. Vomiting stopped on the second day of treatment, appetite improved and diarrhoea regressed by the fourth day. Unfortunately, one case died two days after admission due to marked hypokalaemia. Clinico-pathological and epidemiological aspects of this infection in Egypt are discussed.

A syndrome of chronic diarrhea, vomiting, and failure to thrive was described 35 years ago. The syndrome was caused by damage in the jejunum after ingestion of cow's milk. Symptoms appeared in young infants shortly after introduction of cow's milk formula. Patients had moderate steatorrhea, decreased absorption of D-xylose, and, often, iron-deficiency anemia and hypoproteinemia. They had strong IgA and IgG antibodies to cow's milk. IgE antibodies to cow's milk were negative, as a rule. Indicators of cell-mediated immune reaction to cow's milk proteins were often positive. Patients were tolerant to cow's milk by the age of 3 years. Malabsorption was due to damage to the jejunal mucosa: Varying villus atrophy was associated with inflammation in surface epithelium and lamina propria. The epithelial cell renewal rate increased. Surface epithelial cells decreased in height, with short, furry microvilli and large aggregates of lysozymes. The number of intraepithelial lymphocytes was markedly increased, but normalized during cow's milk elimination. Most of these lymphocytes had alpha/beta T-cell receptors, and many were cytotoxic. Some specimens had an increase in gamma/delta T-cell receptor-bearing cells. In the lamina propria, CD4+ cells predominated, and some of them were activated. IgA- and IgM-containing cells were markedly increased during cow's milk exposure, but IgE cells were not abnormal. The density of eosinophils was moderately increased. Secretion of interferon-gamma by cells isolated from patients' intestines was markedly increased. Morphologic and immunologic findings suggest that T-cell-mediated reaction to proteins in cow's milk is present in the small intestines of patients with this syndrome and causes this enteropathy.

The best procedure for the treatment of morbid obesity has not yet been defined. Biliopancreatic diversion is one of the techniques available, but its results have not been sufficiently documented and the addition of a subtotal gastrectomy to the diversion so as to avoid leaving a blind non-functioning stomach, is still questionable. The purpose of this paper is to report our experience with our first 149 consecutive patients who were treated by biliopancreatic diversion with subtotal gastrectomy for morbid obesity. Operative mortality was 3% and morbidity 12%. The weight loss was marked during the first 6 months and decreased during the following 12 months. The weight stabilized at 2 years and there was subsequently a small increase. In only two out of 48 cases was the weight loss less than 25% of the initial weight at 2 years. The undesirable side-effects were diarrhea in 6%, vomiting in 9% and dyspepsia in 4%. The intervention leads to a malabsorption of carotene, iron, albumin and calcium. Except for carotene the deficiencies were corrected by oral supplement. In two patients, with resistant deficiencies, the diversion was reversed. Eighty-eight percent of the patients are satisfied with this intervention. At 2 years, 70% have reached their weight loss objective without any major side-effects or nutritional deficiencies, but in 14% the outcome of the procedure must be considered unsatisfactory. Biliopancreatic diversion with subtotal gastrectomy is a major operation, but it gives encouraging results so far.

A six-month-old beagle was presented with a three-month history of failure to gain weight, lethargy, intermittent vomiting and seizures. Hypoglycaemia, portosystemic shunt, lead intoxication, gastrointestinal diseases and hereditary metabolic disorders were considered. Laboratory test results of low serum cobalamin (Cbl) concentrations, anaemia, leucopenia and methylmalonic aciduria while the dog was receiving a balanced commercial canine diet were suggestive of a congenital selective Cbl malabsorption. Treatment with repeated injections of parenteral cyanocobalamin (CN-Cbl) at 50 microg/kg every two weeks corrected the Cbl-deficient state and reversed all the clinical abnormalities. Selective Cbl malabsorption has previously been described in giant schnauzers and border collies and represents a unique readily treatable hereditary metabolic disorder.
