    Description / Table of Contents: Summary The long-term variation of the mean δ13C-value of breath-CO2 of Europeans (base value −26‰) was ±1‰ over a period of several months. However, the ingestion of products from corn, a C4-plant, caused remarkably higher shifts. In a fasted state and during rest a stability of the base value of ±0.3‰ could be attained for several hours. Longer fasting periods imply a shift of the CO2-δ-value due to the metabolism of body products. — By a change of the main energy source to corn products the δ13C-base line could be shifted to −18‰ within one day. After this shift even the metabolism of products from C3-plants could be investigated. The degradation curve and the integral degradation of fats were largely dependent on the method of application, and the base value largely interfered with the results. The period of maximum disintegration for a naturally and uniformly labelled fat was different from that of an artificially labelled trilinoleate. The results shall be used for the adjustment and the correction of the base line in13C-breath tests, especially with patients under parenteral nutrition.
    Notes: Zusammenfassung Der mittlere δ13C-Wert im CO2 der Atemluft von Europäern (Basiswert −26‰) zeigt eine Langzeitschwankung über mehrere Monate von ±1,0‰; der Verzehr von Produkten aus C4-Pflanzen (z. B. Mais) hat allerdings erheblich höhere Änderungen zur Folge. Im Nüchternzustand und in Ruhe wird während 6 h eine Stabilität des Basiswertes von ±0,3‰ erreicht; nach längeren Nüchternphasen kann aber der Abbau körpereigener Substanzen zu Verschiebungen führen. Durch Umstellung der Energieversorgung auf Maisprodukte ist es möglich, den Basiswert innerhalb eines Tages auf −18‰ zu heben; dann läßt sich auch der Abbau von Substanzen aus C3-Pflanzen verfolgen. Der Verlauf und die Rate des Abbaues von markierten Fetten sind stark von der Art der Applikation abhängig, und die Messung des Gesamtumsatzes wird durch den Untergrund stark beeinträchtigt. Der Zeitpunkt des maximalen Abbaues von uniform markiertem Fett (Sojaöl) unterschied sich von dem eines in der Carboxylgruppe markierten Trilinoleats. Die Resultate sind Grundlage zur Einstellung bzw. Korrektur von Basiswerten bei13C-Atemtests, besonders bei Patienten mit parenteraler Ernährung.

    Notes: Summary Gastrointestinal motility disorders induced by diabetes mellitus are most commonly manifested in the colon, and are considered to be an expression of diabetic autonomic polyneuropathy. In this study, for the first time, the intrinsic nervous system of the bowel has been subjected to an ultrastructural and morphometric examination in rectal biopsy material obtained from diabetics with and without diabetic enteropathy. In patients with diabetic enteropathy, the nerves of the submucous plexus (Meissner's plexus) revealed significant swelling of the axons, as an expression of neural degeneration. Furthermore, in about a half of these patients, thickening of the basal membrane of Schwann's cells was also detected. Additional, although unspecific, changes found in the diabetics were a quantitative increase in the lysosomes, lipofuscin and glycogen in the Schwann cells. The ultrastructural findings represent evidence for the presence of an intrinsic autonomic polyneuropathy in diabetics with diabetic enteropathy. At the same time, they indicate that the diagnosis of diabetic enteropathy is no longer merely an “exclusion” diagnosis.

    Development of height and weight in children with diabetes mellitus: Report on two prospective multicentre studies, one cross-sectional, one longitudinal (1992)

    Notes: Abstract Optimal regimen for insulin therapy should lead to normal longitudinal growth and weight gain in children with diabetes mellitus. However, reports published so far indicate that this goal of paediatric diabetology is currently not achieved in a considerable number of patients. In a cross-sectional sample of 89 children with insulin dependent diabetes mellitus (IDDM) for more than 3 years, we found the relation of height to weight to be significantly different compared to 102 healthy school children of similar age. Using bivariate analysis, body shape in these children with diabetes was shifted towards small and obese (P〈0.05) compared to control children. We subsequently initiated a longitudinal study and followed children from the onset of diabetes for the following 3 years, recording height, weight and bone age as well as glycosylated haemoglobin and daily insulin requirement. At diagnosis, height SDS was identical in children with IDDM (+0.04±0.10) compared to control children (−0.07±0.10; M±SE), while weight SDS was −0.26±0.10 in children with diabetes (controls: +0.01±0.1). Bone age was identically retarded in newly diagnosed IDDM children (−0.73±0.12 SDS) and in our control group of children from the same regional background (−0.50±0.12; n.s.). In this group of children with diabetes mellitus followed prospectively, height to weight relationship differed from controls after 2 and after 3 years of the disease (P〈0.05). At 2 years, body size in children with diabetes was shifted towards taller and heavier compared to controls, while at 3 years, the relation of height to weight was even more abnormal with increased obesity but a reduction of standardized height. This is the same relation encountered in the cross-sectional sample of children with a duration of diabetes beyond 3 years. These data demonstrate that even modern insulin therapy does not guarantee normal development of height and weight in children with IDDM.
