    Description / Table of Contents: Résumé Cette étude confirme nos premiers résultats démontrant une sécrétion d'insuline importante et prolongée chez des patients présentant une azotémie élevée et une intolérance au glucose. Elle montre que les caractéristiques des sécrétions d'hormone de croissance et de glucagon ne sont pas modifiées chez ces patients bien nourris qui présentent des maladies rénales avec hyper azotémie : les valeurs à jeun sont dans les limites normales et la réponse au cours d'un test de tolérance au glucose d'une durée de 5 h est normale, excepté chez un homme ayant une maladie de Fabry chez lequel une très importante augmentation de l'hormone de croissance dans le plasma a été observée au début du GTT lorsque le glucose du sang s'élevait. Il n'y a pas d'augmentation d'hormone de croissance dans le plasma pendant le test de tolérance au glucose de 60 min. Les valeurs du glucagon plasmatique sont normales.-Cette étude effectuée sur 11 sujets montre que la diminution de la tolérance au glucose qui est observée chez les patients azotémiques en présence d'une sécrétion d'insuline importante et prolongée ne peut pas être mise en relation avec des anomalies de sécrétion de l'hormone de croissance ou du glucagon.
    Abstract: Zusammenfassung Die vorliegende Untersuchung bestätigt unsere früheren Resultate, die bei Patienten mit Urämie und Störungen der Glucosetoleranz eine ausgeprägte und verlängerte Insulinsekretion zeigten. Sie ergibt ferner, daß das Verhalten der Sekretion von Wachstumshormon und Glucagon bei diesen Patienten mit chronischen Nierenerkrankungen, die sich in gutem Ernährungszustand befinden, nicht verändert war: Die Nüchternwerte lagen im Normbereich und während eines 5stündigen Glucosetoleranztestes kam es zu einer normalen Reaktion, wenn man von einem Mann mit Fabry'scher Erkrankung absieht, bei dem zu Beginn des GTT während des Blutzuckeranstieges eine sehr starke Zunahme des Wachstumshormons festzustellen war. Während des einstündigen i.v. GTT stieg das Plasma H.G.H. nicht an. Die Plasma-Glucagonspiegel verhielten sich normal.— Diese Untersuchungen an 11 Probanden zeigen, daß die verringerte Glucosetoleranz bei urämischen Patienten bei gleichzeitig verstärkter und verlängerter Insulinaus-schüttung nicht auf eine gestörte Sekretion von Wachstumshormon oder Glucagon zurückgeht.
    Notes: Summary This study confirms our first results showing large and prolonged insulin secretion in patients with azotaemia and glucose intolerance. It shows that the pattern of growth hormone and glucagon secretions was not modified in these well nourished patients with chronic renal diseases and hyperazotaemia : the fasting values were in the normal range and the response during a 5 h glucose tolerance test was normal, except in one man with Fabry's disease, in whom a very large increase in plasma growth hormone was observed at the beginning of the GTT when the blood glucose increased. There was no increase in plasma H.G. H. during the intravenous glucose tolerance test of 60 min. Plasma glucagon values were normal.-This study done on 11 subjects shows that the diminished tolerance to glucose observed in azotaemic patients in presence of a large and prolonged insulin secretion cannot be related to abnormalities in growth hormone or glucagon secretion.

    Notes: Summary The aim of this study was to discover the frequency, severity and causes of hypoglycaemic reactions in Type 1 (insulin-dependent) diabetes. One hundred and seventy-two outpatients answered a questionnaire which also inquired about their feelings, opinions and fears with respect to insulin reactions. Hypoglycaemic reactions were common: a mild episode occurred at least once a month in 58% of patients, and at least one severe reaction (defined by the need of assistance) during the past year was described by 26%. Both were positively related to the duration of the disease. However, the occurrence of mild and severe attacks was not related. In addition, patients prone to mild hypoglycaemia seem to be somewhat different from patients prone to severe attacks in their attitudes towards the disease. For example, mild reactions are more frequent in patients devoted to ‘perfect’ control, whereas severe episodes were observed more frequently in those who did not think that controlling diabetes is a difficult task. The social consequences of any reaction, even mild, were important in 30% of the patients. Twenty-one percent of the patients said that the short-term risks of a hypoglycaemic reaction, even if correctly treated, were high and 6% said that the fear of having a reaction was unbearable. In addition to rational explanations, emotional factors were given as a cause of hypoglycaemia (14%), but 11% of cases felt that attacks occured without any obvious reason in spite of correct management.
