The reliability and validity of the 24-hour dietary recall method was tested statistically by comparing observed with recalled intakes of kilocalories and protein. Data on observed intake of 28 children, aged 10 through 12, with asthma, cystic fibrosis, or diabetes, participating in a summer camp program, were obtained by unobtrusive observation. The same subjects were interviewed within 24 hours after the observation. Intakes of kilocalories and of protein were computed for both observed and recalled data. The two sets of data were compared by paired t-test and regression analysis. A large and significant difference was found between mean recalled and mean observed intakes for both kilocalories and protein. This coupled with a low but significant coefficient for reliability limits the usefulness of this dietary assessment tool in the age group studied.

Using the gastric insufflation method, 5 cases of pancreatic calcification have been detected in a series of 60 patients with cystic fibrosis. All patients were over 5 years of age. Four of them showed a diabetic curve at glucose tolerance test and 2 have recently developed frank diabetes mellitus. The value of gastric distension by gas in the radiological detection of pancreatic calcification and the relatively high frequency of such calcification in cystic fibrosis are emphasized. The pathogenesis of the calcific change and its clinical significance are briefly discussed.

We have recently shown that hypersomatostatinemia is a feature of cystic fibrosis (CF) when these patients have CF-associated pancreatogenic diabetes mellitus (CFDM). To address the possibility that patients with CFDM might have suppressed pituitary growth hormone (GH) release as a result of increased plasma somatostatin, GH secretion in 8 CFDM patients and 8 normal male controls was studied using a standard arginine infusion stimulus. Concentrations of the GH-dependent peptides, insulin-like growth factor I (IGF-I) and insulin-like growth factor binding protein 3 (IGFBP-3) were also measured. We found that mean GH concentrations in the CFDM group were significantly increased (p < 0.05) rather than decreased at the 30-min (12.3 +/- 3.6 vs. 3.8 +/- 1.9 ng/ml), 45-min (15.4 +/- 2.9 vs. 6.1 +/- 2.3 ng/ml) and 60-min (13.2 +/- 2.3 vs. 6.2 +/- 2.2 ng/ml) time points of study. Mean GH area under the curve (633 +/- 128 vs. 249 +/- 107 ng/ml) was also significantly greater (p < 0.05) in the CFDM group. Despite higher GH levels in the CFDM patients, their IGF-I and IGFBP-3 concentrations were low. We conclude that plasma somatostatin elevations in the CFDM group are not of sufficient magnitude to suppress pituitary GH release. Decreased levels of growth mediating peptides in the relatively malnourished CF subjects suggest a pattern of malnutrition-induced GH resistance which may contribute to poor weight and height gain.

Because the lifespan of patients with cystic fibrosis is now longer, both pediatricians and adult care physicians are involved in the health care strategy. Respiratory manifestations occur due to bronchial dilatation and chronic bronchial infection, mainly due to Staphylococcus aureus and Pseudomonas. Episodes of adult infection are frequent and death usually results from respiratory failure. Characteristically, the disease also involves exocrine pancreas insufficiency. Other intestinal tract manifestations include meconial ileus and liver disease which may reach the stage of biliary cirrhosis. Nutritional disorders are frequent. Clinically there are respiratory and digestive tract disorders, pansinusitis and frequent nasal polyposis, sometimes associated with diabetes mellitus or joint pain. Male sterility results from bilateral agenesia of the vas deferens and in the female, fertility is decreased although pregnancy is possible. Clinical presentation suggests the diagnosis which is confirmed by a sweat test and genetic analysis. Care should be provided by a centre specialized in cystic fibrosis. The main treatments rely on respiratory physical therapy, antibiotics and gastroprotected pancrease extracts.

Cystic fibrosis is an autosomal recessive disorder which affects one in 2500 live births. It is a multisystem disease and has a variety of presentations. The major clinical features affect the gastrointestinal and respiratory tracts. Severe respiratory disease, diabetes and gastroesophageal reflux are common features of concern to anaesthetists. Improved care of young patients has allowed many to survive into adulthood. Lung transplantation has significantly improved the outlook for many patients. At Alfred Hospital, 74 patients with cystic fibrosis underwent 149 procedures from January 1978 to January 1994, with a mortality of 0.6% (95% CI 0.4%-0.8%). This retrospective cohort study describes the anaesthetic management and perioperative care of these patients. Most of the anaesthetics were for procedures related to cystic fibrosis but 12% were for unrelated conditions. Cystic fibrosis related procedures include diagnostic, venous access, enteral feeding procedures, treatment of complications of cystic fibrosis and lung transplantation. Despite extremely poor respiratory function, these patients can be managed with acceptably low postoperative mortality (1%). Pre- and postoperative care must be directed towards optimal clearance of viscous respiratory secretions. Procedures need to be planned so that optimal care can be given by each member of the team caring for cystic fibrosis patients.

Medical records of 132 patients attending an adult cystic fibrosis (CF) clinic were analysed to define the prevalence and clinical significance of diabetes mellitus (DM) in CF. Eighty four (63.6%) had normal blood glucose levels, 30 (22.8%) had hyperglycaemia only during intercurrent illness and 18 (13.6%) had DM. No significant differences were noted between the diabetic and non-diabetic groups for age, gender, height, weight, body mass index (BMI), forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) and pancreatic supplementation. Patients with hyperglycaemia during intercurrent illness had significantly lower BMI, FEV1% and FVC% than those with normal blood glucose levels. Of the diabetics four were managed on diet, three received oral hypoglycaemic agents and eleven were insulin requiring. The prevalence of DM in CF is considerable, severity of CF does not correlate with development of overt DM, and CF patients should be screened for DM by an oral glucose tolerance test on reaching adulthood.

Traditional opinion holds that patients with cystic fibrosis (CF) develop impaired glucose tolerance or diabetes due to insulinopenia caused by fibrosis of the pancreas. However, studies on the dynamics of insulin secretion and peripheral insulin action have yielded conflicting results. We studied 18 patients with CF (9 male, 9 female, age 15-29 years) and 17 healthy control subjects (8 male, 9 female, 20-32 years). Oral glucose tolerance tests and combined i.v.-glucose-tolbutamide-tests were performed on separate days in fasting subjects. Bergman's "Minimal Model" was used to quantitate both peripheral insulin sensitivity (SI) and insulin-independent glucose disposal (glucose effectiveness; SG). Based on National Diabetes Data Group criteria, 4 patients were classified as diabetic (22%; CF-DM), 3 patients (17%) had impaired glucose tolerance (CF-IGT) while glucose metabolism was normal in 11 patients (61%; CF-NGT). Irrespective of the degree of glucose tolerance, the insulin response to oral glucose was not reduced but delayed, up to 60 min in the CF-IGT/DM group. First-phase insulin release (0-10 min) after i.v.-glucose was significantly lower in CF patients (29% of healthy controls; P < 0.0001), with no difference between the CF-NGT and CF-IGT/DM groups. Insulin release following tolbutamide injection was only marginally reduced in CF patients (64% of controls). In contrast, SI was significantly reduced in the subgroup of CF patients with abnormal glucose metabolism (CF-IGT/DM: 0.97 +/- 0.16 x 10(-4) l/min/pmol; control group: 1.95 +/- 0.25; P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Data from 1348 patients with cystic fibrosis in mid-Europe show that the prevalence of diabetes mellitus in these patients is 4.9%, that diabetes develops in more female than male patients with cystic fibrosis during childhood and adolescence and at a younger age, and that diabetes mellitus is more likely to affect delta F508 homozygous patients.

Carbohydrate intolerance and frank diabetes mellitus (DM) are recognised features of cystic fibrosis (CF), but their cause has not been established. Damage to the islet cells due to pancreatic fibrosis is the most common explanation. The relationship between the genotype and the occurrence of diabetes mellitus has been examined in 21 cystic fibrosis patients attending our out-patient chest clinics. DNA samples were tested for the presence of the most common mutation (delta F508) and the results related to the degree of carbohydrate intolerance. We found that in CF patients over 18 years of age diabetes is more frequent among those homozygous for the delta F508 allele than the heterozygotes (P < 0.05). Those homozygous for delta F508 were diagnosed as CF at an earlier age than the heterozygotes (P < 0.05). Both the mean age and the female/male ratio were similar in the diabetic and non-diabetic groups. The prevalence of the delta F508 allele was similar to that expected in a random sample of East Anglian cystic fibrosis patients. These data suggest that the occurrence of diabetes mellitus in patients with cystic fibrosis is related to the genotype, which could be secondary to the way the genetic factors influence the degree of pancreatic disease and its rate of progression.

Children with cystic fibrosis represent the largest group referred for, and undergoing, heart-lung transplantation at our institute. Between June 1988 and July 1993, 76 patients were accepted for transplantation, of whom 25 were transplanted, while a further 36 died waiting. Those transplanted ranged from 5-18 years of age and included 13 males and 12 females. Organs were used from donors matched by ABO blood group, size and cytomegalovirus (CMV) status. Post-transplant maintenance immunosuppression comprised cyclosporin A, azathioprine and prednisolone. Anti-thymocyte globulin and high dose methylprednisolone were given peri-operatively and for acute rejection episodes. Actuarial survival was 67% at 1 year, 61% at 2 years and 54% at 3 years. Obliterative bronchiolitis (OB) has occurred in 13 patients (52%) and was the major cause of mortality and morbidity. In three patients, OB was associated with the development of tracheal anastomotic stenosis. Other complications included diabetes mellitus (n = 9), pancreatitis (n = 1) and hypertension (n = 8). Despite these problems, those surviving the first year post-transplant showed a mean FEV1 of 71% (compared to 29% pre-transplant) and enjoyed an overall improved quality of life.
