Among 88 unselected patients with chronic pancreatitis 35% (95% confidence limits 25 to 46) had insulin-dependent diabetes, 31% (21% to 41%) had non-insulin-dependent diabetes or impaired glucose tolerance (by intravenous glucose tolerance test), and 34% (24% to 45%) had normal glucose tolerance. B cell function measured by C-peptide concentration after 1 mg glucagon IV correlated with the pancreatic enzyme secretion (meal stimulated duodenal lipase content). B cell function was preserved to a greater extent (P less than .01), and glycosylated hemoglobin and fasting level of glucose were lower (P less than .01 to .05) in the 31 patients with pancreatogenic diabetes than than in 35 otherwise comparable patients with type I (insulin-dependent) diabetes, yet daily insulin dose was similar in the two groups. Glucagon stimulated C-peptide was inversely correlated to glycosylated hemoglobin in insulin-dependent patients with pancreatogenic diabetes and in type I diabetes. Since body mass indices were identical in the two groups, better glucoregulation was not due to reduced food intake or malabsorption in pancreatogenic diabetes. Rather residual B cell function and/or different secretion of other pancreatic hormones in pancreatogenic diabetes may account for different metabolic control in type I IDDM compared with insulin-dependent pancreatogenic diabetes.

Three hundred and sixteen patients with cystic fibrosis were seen at the Brompton Hospital during 1965-83; 178 (56.3%) of them were male and 136 female, and their ages ranged from 12 to 51 years. Most patients presented in infancy with respiratory symptoms and malabsorption, but 19 (6%) were diagnosed in adult life, three in their 30s. Pulmonary disease was almost universal (99.7%), being responsible for 97% of all deaths and three quarters of hospital admissions. All patients had developed a productive cough by the age of 21 and over half before the age of 5. Many complained of wheezing, but reversible airflow obstruction was present in only 40% of those tested. Minor haemoptysis was very common (62%), but major episodes less so (10%). Pneumothorax was seen in 61 cases (19%), and was often recurrent. Some irreversible airflow obstruction was present in all patients with pulmonary disease. Two patients have been followed for over 20 years without showing appreciable decline in lung function. Thirty five patients (11%) had no symptoms of malabsorption. Acute meconium ileus equivalent was seen in 16% and a chronic partial obstruction with episodic symptoms in a further 19%. Diabetes mellitus developed in 36 patients, 13 of whom were insulin dependent. Hepatomegaly was common (29%), often occurring without abnormal results in biochemical tests of liver function; only 1% of patients developed portal hypertension with varices and ascites. Skin reactions to at least one common allergen, including Aspergillus fumigatus, were positive in 70%, but very few patients suffered from hay fever or eczema. One hundred and twenty one patients have died, 97% from infection or other pulmonary complications, and 195 were alive in December 1983 (mean age 23 years). Seventy eight per cent of patients were in full time education or full or part time employment, or were housewives, and only 41 were unemployed for reasons for health. Many patients are married and 10 women have borne children. Most patients were admitted to hospital only three or four times during the period of follow up and 50 individuals (16%) have never been in hospital at all. The improvement in prognosis and quality of life for adults with cystic fibrosis should encourage a positive attitude in those who care for them.

To determine the effect on blood glucose of removal of protein from wheat products, healthy volunteers took test meals of white bread made from either regular or gluten-free flour. After bread made from gluten-free flour, the blood-glucose rise was significantly greater. This corresponded with a significantly more rapid rate of digestion in vitro and reduced starch malabsorption in vivo as judged by breath-H2 measurements. Addition of gluten to the gluten-free bread mix did not reverse these effects. Factors associated with unprocessed wheat flour, such as the natural starch-protein interaction, may therefore be important in wheat products in reducing both their rate of absorption and glycemic response. They may have implications in the dietary management both of diabetes and of diseases where small intestinal absorptive capacity is impaired.

Following consideration of the nosological role of hyperglycemic states in psychiatry the case report of a fifty-five year-old patient is presented suffering from fatty cell degeneration of the liver and a relapsing pancreatitis due to chronic alcoholism. After a long period of abstinence without previously known diabetes mellitus a sudden ketoacidotic coma developed with maximum serum glucose level of 2020 mg%. Having emerged during coma treatment Wernicke's encephalopathy passed into Korsakoff's syndrome the main features of which remained unchanged for more than one year. In this case thiamine deficiency of different pathogenetical origin is discussed: defective exogeneous availability due to malabsorption; depletion of endogeneous thiamine stores due to enlarged requirements for glucose oxidation during coma therapy; antimetabolic effects to thiamine by nitroimidazole-derivatives administered parenterally.

Carbohydrate foods that are slowly digested appear beneficial in the management of diabetes and hyperlipidemia. This study determined the effect of endogenous and added phytic acid as well as Ca on the in vitro rate of starch digestion and in vivo blood glucose response to navy bean flour, prepared as unleavened bread. Removal of phytic acid from and addition of Ca to navy bean flour increased the starch digestion in vitro and raised the glycemic response in vivo while readdition of phytic acid to dephytinized flour produced the opposite effect. Carbohydrate malabsorption assessed by breath H2 measurement related negatively to glycemic response but the changes observed were much lower than the changes in glycemic response. This study confirmed the role of both added and endogenous phytic acid in slowing the in vitro rate of starch digestibility and in vivo glycemic response to legumes and the ability of Ca to modify this effect.

We report the first case of the Pancreatic fibrosis calcification syndrome (PFCS) in a Liberian. The patient presented with the classical features of the syndrome - a history of recurrent abdominal pain, diabetes mellitus, malabsorption and pancreatic calcification on plain abdominal X-ray. The patient also has situs inversus; we believe that this combination is a casual one. Since describing this case, five more cases have been diagnosed; we believe that this condition is not rare in Liberia.

A 14 year-old boy with coeliac disease and poorly treated diabetes mellitus and pulmonary tuberculosis due to INH resistant BK presented with a permanent malabsorption of rifampicin. Pharmacokinetics of rifampicin was studied after oral administration and intravenous injection. Treatment of diabetes and coeliac disease did not improve the situation. Tuberculosis was cured by pyrazinamide and ethambutol.

The serum levels of apolipoprotein A-IV (apo A-IV) were measured by rocket immunoelectrophoresis in disease-free humans, at fasting and after oral and intravenous fat administration. The studies were extended to patients with chronic pancreatitis, malabsorption syndrome, to postoperative patients on total parenteral nutrition and to patients with liver diseases, cholestasis, diabetes mellitus and chronic renal failure. Oral fat ingestion resulted in an increase of apo A-IV levels which remained elevated even when the postprandial hypertriglyceridemia had disappeared. A transient increase in apo A-IV levels was observed after intravenous fat infusion but the level declined simultaneously with decreases in triglyceride levels. Levels of serum apo A-IV were decreased under conditions where decreased fat intake or malabsorption of nutrients might have been present, such as in patients with chronic pancreatitis, malabsorption syndrome, acute hepatitis in the early stage, obstructive jaundice and in postoperative patients on total parenteral nutrition. On the other hand, the apo A-IV levels were high in patients with chronic renal failure and in those with diabetes mellitus and proteinuria.

Immune complexes have been previously reported in the serum of patients with cystic fibrosis. This study was undertaken to relate the finding of complexes with the clinical features of the disease. Immune complexes detected by the 125I-C1q binding assay were found in the sera of 17/60 (28%) of patients with cystic fibrosis (CF). There was no association between the finding of raised levels of immune complexes and duration of chest symptoms, duration of daily sputum production, age, sex, weight, atopy, the presence or absence of malabsorption, pneumothorax, diabetes, Aspergillus precipitins or specific bacterial pathogens in the sputum. There was however a correlation between the finding of increasing circulating immune complexes and decrease in the respiratory function; forced expiratory volume in 1 sec (P less than 0.001) and forced vital capacity (P less than 0.005); also with weight (P less than 0.02). It is possible that the finding of immune complexes, at low levels, in cystic fibrosis are the result of tissue damage rather than its cause.

A 50% small bowel bypass was performed in diabetic rats (streptozotocin-treated) and in normal rats. Normal rats and diabetic rats were used as controls. Values of fasting blood glucose and oral glucose tolerance test showed a normalization and the disappearance of glycosuria, polyuria, polydipsia and hyperphagia in diabetic rats after surgery. Mean loss of weight 3 months after surgery was 9.1% in normal bypassed rats and 60.5% in the diabetic controls. After an initial postoperative weight loss of 33.4%, the diabetic bypassed rats gained subsequently their previous weight plus an increase of 7.2%. Improvement in carbohydrate metabolism appears to be independent of loss of weight and decrease in food intake in lean diabetic rats. Amelioration of diabetes after jejunoileal bypass is the result of several metabolic consequences, particularly the malabsorption of carbohydrates, fats and amino acids.
