Glucose, insulin, and growth hormone values were studied prospectively in 75 premature infants during the first five days after birth. Intravenous glucose was given at a mean rate of 4.7-4.9 mg./kg./min. (range 3-7). Mean birth weight was 1,394+/-47 gm. (mean+/-S.E.M.). Blood glucose values were significantly higher on days 1 and 2 than on days 3 to 5. Hypoglycemia (blood glucose less than 20 mg./100 ml.) occurred in two SGA and one AGA infants. On the other hand, hyperglycemia (greater than 125 mg./100 ml.) was found in 32 of the 75 (42.7 per cent) infants. A significantly greater number of deaths occurred in infants with hyperglycemia (19/32) than in those with normoglycemia (19/32) than in those with normoglycemia (5/43). Mean plasma insulin values were significantly higher on days 1 and 2 (15+/-3 and 18+/-4 muU./ml.) than on days 3 and 4-5 (6+/-1 and 7+/-2 muU./ml.). In addition, mean insulin levels were significantly higher during hyperglycemic than during normoglycemic glucose levels at similar postnatal age. Growth hormone values were higher during the first three days than subsequently, but the values were similar in normoglycemic and hyperglycemic groups. Significant negative correlations were seen between glucose values on the first two days of postnatal life and birth weight, gestational age, and Apgar scores, whereas positive correlations were found with FiO2 and respiratory distress score (RDS).

To evaluate the effects of diabetes mellitus (DM) on fetoplacental circulation, Doppler velocimetry was carried out in diabetic pregnant women (n = 21) and normal pregnant controls (n = 20) every 2 weeks from the 20th week of gestation till term. Blood flow wave form of umbilical artery (Um) and uterine artery (Ut) were measured and the systolic/diastolic ratio (S/D) of Um and Ut calculated. The results showed that the Um and Ut S/D ratio of diabetic mothers with AGA babies (n = 15) and normal controls were not different. The S/D ratio of diabetic women with LGA newborns (n = 6) elevated after the 30th week of gestation, and the time of elevation was in accordance with the accelerating growth stage of LGA fetus. It is suggested that the elevation of S/D ratio may be related to the increasing requirement of blood supply for LGA babies in DM mother.

IgG gliadin antibodies (AGA-IgG) were detected by immunofluorescence in 78 celiac children diagnosed by jejunal biopsy. AGA-IgG were also detected in patients affected by other gastrointestinal disease, in patients with diabetes, in health children and in children with normal mucosa. AGA-IgG were found in 81% of celiac patients, while they were not detected in patients affected by other intestinal or extraintestinal diseases, neither in healthy controls. It is conclude that determination of AGA-IgG is a very specific and sensitive enough screening test before small intestinal biopsy.

Numerous studies have identified perinatal risk factors of neonatal sepsis. Some authors have attempted to develop a score system and have shown that babies with septicemia usually had a significantly higher score than healthy newborns and infants with other diseases. The aim of our study is to verify the validity of a scoring method based on the following items: maternal disease; e.g. diabetes, severe toxemia, infection; rupture of the membranes more than 24 hours before the delivery; foul-smelling amniotic fluid; complicated delivery; Apgar score less than 7; umbilical catheterization; respiratory distress and other neonatal diagnoses leading to operative procedures. We have evaluated four groups of babies, full-term AGA and SGA and preterm AGA and SGA, 84 with septicemia, 105 with other diseases and 210 healthy newborn infants. None of the perinatal risk factors or neonatal diseases was sufficiently predictive of neonatal septicemia. Only the incidence of umbilical catheterization was significantly higher (p less than 0.01) in preterm AGA (37.1%) and SGA (64.7%) babies with septicemia than in preterm healthy AGA (2.8%) and SGA (7.7%) babies; on the contrary, no statistical differences were found between preterm AGA (37.1%) and SGA (64.7%) infants with septicemia and preterm AGA (42.8%) and SGA (66.6%) infants with other neonatal diseases. A score of 1 was assigned for each of the considered items. In the full-term infants a score of 1 or less was found in 100% of the healthy infants. A score of 2-3 was found in 26% of the septicemic infants and in 42% of the infants with other diseases.(ABSTRACT TRUNCATED AT 250 WORDS)

We have discussed the nature of a scleral lens that will allow us to follow changes in aqueous humor glucose levels in animals by a method based on optical rotation and a technique described in an earlier paper. We have shown how this lens can be micro-miniaturized and can be used in humans as a non-invasive glucose monitor. We have described preliminary experiments designed to show the correlation between the blood glucose assay (BGA) and the aqueous humor glucose concentration as determined by chemical assay (AGA) and by optical rotation determination (ARD). The last mentioned has been obtained by paracentesis directly into a microcell used in conjunction with instrumentation capable of measuring optical rotations as low as 0.0013 degrees (4.5") corresponding to 20 mg/dl glucose with a sensitivity of 0.0001 degrees (0.36"). The variability among normal rabbits as a function of individuality and diurnal changes is described, and the correlation between AGA and ARD shown to be essentially 1.0. Such rabbits are examined when undergoing very rapid decreases in BGA (insulin treatment) or very rapid increases in BGA (bolus of glucose). The AGA and ARD are shown to lag behind the BGA, and this is discussed in terms of the rate of change of BGA with respect to time and its concomitant change in AGA/ARD as well as a simple procedure that would materially reduce this lag.

Coeliac disease occurs more commonly in children with insulin-dependent diabetes mellitus (IDDM) than in the general population, but the prevalence of coeliac disease in adults with diabetes is unknown. We therefore screened an adult hospital-based diabetic population using IgA antigliadin antibody (IgA-AGA) to identify those patients requiring intestinal biopsy. In 1 year, 1789 patients (43% IDDM, 57% NIDDM) were screened, and 73 had raised IgA-AGA. Of these patients, 49 agreed to duodenal biopsy and 13 (10 IDDM) had coeliac disease. Selective IgA deficiency was found in eight patients, one of whom had coeliac disease. Of these 14 patients with newly diagnosed coeliac disease, four had microcytic anaemia, nine a low serum ferritin, and four a low albumin-corrected calcium. Eight patients had symptoms which improved on gluten withdrawal. Dietary compliance was maintained in 6/8 symptomatic patients, but only in 1/6 without symptoms. Included in the 1789 patients were four (all IDDM) with known coeliac disease. The overall prevalence of coeliac disease in adult patients with IDDM was 1:50 compared with 1:340 in NIDDM. Coeliac disease is common in adults with IDDM and may cause malabsorption and ill health. It should be suspected in any IDDM patient with gastrointestinal symptoms or unexplained anaemia.

The function of insulin receptor and IGF-1 receptor was investigated in placentas from 10 healthy control mothers, 8 diabetic mothers with appropriate-for-gestational-age babies (AGA group) and 9 diabetic mothers with large-for-gestational-age babies (LGA group). None of the diabetic mothers were obese before pregnancy; their blood glucose was well controlled during pregnancy and glycosylated HbA1c was 6.52 +/- 0.71% (M +/- S.E.). Insulin and IGF-1 receptors were partially purified from placentas using wheat germ agglutinin chromatography. The insulin-binding capacity was significantly increased in both the AGA and the LGA groups compared to the control, whereas the IGF-1 binding capacity was similar in the three groups. Autophosphorylation studies were performed with partially purified receptors equalized for similar binding capacity, then immunoprecipitated with anti-insulin receptor antibody or anti-IGF-1 receptor antibody. Insulin-stimulated 32P-incorporation into the insulin receptor beta-subunit was increased by 133% in the LGA group versus the control, whereas incorporation in the AGA group was equivalent to the control. Insulin-stimulated tyrosine kinase activity of the receptor preparation for histone H2B phosphorylation was also significantly increased in the LGA group compared to the control. 32P-incorporation into beta-subunit IGF-1 receptor and IGF-1-stimulated tyrosine kinase activity did not show any significant differences among the three groups. The data in the present study suggest that elevated insulin receptor kinase might be involved in fetal overgrowth in diabetic mothers.

The purpose of this study was to determine whether infants sufficiently affected by maternal diabetes or hypertension to exhibit abnormal growth (macrosomia, growth retardation) would also display significant alteration in timing of pulmonary maturity (delay or acceleration, respectively). We studied 874 consecutive women with fetal pulmonary maturity testing prior to delivery. Patients were stratified by birth weight into fetal size categories (small for gestational age [SGA], appropriate for gestational age [AGA], large for gestational age [LGA]). Cases were compared based on maternal disease, fetal size categories and pulmonary maturity testing results. Pulmonary maturity rates based on both phosphatidylglycerol (PG) and lecithin/sphingomyelin ratio (L/S) did not differ between term LGA infants of diabetic mothers (97%) and term LGA (80%) or AGA (97%) infants of non-diabetic, non-hypertensive mothers. When compared based on PG alone, there was no difference between the rate of positive PG in term AGA infants of non-hypertensive, non-diabetic mothers (75%) and that seen in the other pregnancy groups (33-80%). Breakdown by gestational age revealed no significant differences in maturity rates between the study groups. Macrosomic diabetic infants and growth-retarded hypertensive infants are no different from controls in their timing of fetal pulmonary maturation.

We have sequenced the first fish (zebrafish, Brachydanio rerio) lipoprotein lipase (LPL) cDNA clone. Similarities were found in mammalian LPL cDNA, but the codon spanning the last two exons (which is thus split by the last intron) is AGA (Arg) as opposed to TGA in mammals. Exon 10 is thus partially translated. These results were confirmed with rainbow trout (Oncorhynchus mykiss). We also investigated whether mammal TGA coded for selenocystein (SeCys), the 21st amino acid, but found that this was not the case: TGA does not encode SeCys but is a stop codon. It thus appears that the sense codon AGA (fish) has been transformed into a stop codon TGA (human) during the course of evolution. It remains to be determined if the "loss" of the C-terminal end of mammalian LPL protein has conferred an advantage in terms of LPL activity or, on the contrary, a disadvantage (e.g., susceptibility to diabetes or atherosclerosis).

To ascertain the specificity of IgA and IgG antigliadin (IgA-AGA, IgG-AGA), IgA-antireticulin (R1-ARA), and antiendomysial (AEA) antibodies for the diagnosis of celiac disease, we evaluated 133 type I diabetic children aged 1.4-28.4 years (mean 14.1 +/- 6.6), with diabetes from onset to 20.5 years. Fifty-three patients were considered at onset and 49 of these also during follow-up. IgA-AGA and IgG-AGA were determined by enzyme-linked immunosorbent assay (ELISA), R1-ARA and AEA by indirect immunofluorescence. IgA-AGA were positive in 20 of 133 (15%), IgG-AGA were positive in seven of 133 (5.26%), while R1-ARA and AEA were positive in three patients. At the onset of disease we found elevated IgA-AGA in 17 of 53 (32%) patients, IgG-AGA in four (7.55%) patients, three of them with IgA-AGA as well; R1-ARA and AEA were present in three (5.66%) patients, all with high IgA-AGA levels. During 1-10 year follow-up IgA-AGA decreased to within the normal range in 13 patients, with elevated IgA-AGA at onset but without R1-ARA and AEA; in four patients with high IgA-AGA at onset, IgA-AGA remained constantly elevated as did R1-ARA and AEA in three of them; and two patients, without IgA-AGA, R1-ARA, and AEA at onset, became positive for all three antibodies. Intestinal biopsy confirmed a diagnosis of celiac disease in five of these with IgA-AGA, R1-ARA, and AEA, but not in one patient with persistent IgA-AGA but no AEA and R1-ARA, suggesting that R1-ARA and AEA are more reliable markers for the screening of celiac disease in type I diabetic patients.
