[Serum gastrin level following duodenal and gastric stimulation with acetylcholine in the dog].

Before and during instillation of a solution of 1% acetylcholine into the duodenum and stomach of 13 mongrel dogs serum gastrin levels were measured at 5 min intervals. After gastric stimulation a sustained rise of serum gastrin concentration was observed. After duodenal stimulation gastrin levels rose only slightly. The multiple factors responsible for this phenomenon necessitate further investigations.

The influence of resection of the small intestine on gastrin levels.

In 16 dogs, serum gastrin levels were determined after resection of the distal and proximal half of the small intestine. The response to feeding was significantly increased after intestinal resection. Higher postresectional levels were reached after resection of the proximal half of the intestine. This may be evidence that the proximal half of the small intestine, in addition to the liver and kidney, plays an important role in the inactivation of endogenous gastrin.

The severity of alcohol withdrawal is not age dependent.

Age has been considered to contribute to the severity of the alcohol withdrawal syndrome (AWS). To evaluate the relationship between age and the severity of the AWS, we examined 723 alcoholics [518 males, 205 females, mean age (+/- SD): 42.8 +/- 10.5 years, mean duration of alcohol dependence: 11.0 +/- 8.0 years] consecutively referred to a unit for detoxification of alcoholics in a general hospital. The severity of the AWS was assessed by the AWS scale of Wetterling et al. (1997; Alcohol and Alcoholism 32, 753-760). The history of alcohol abuse as well as drinking behaviour in the last 6 months was assessed by a semi-structured interview. There were 41 alcoholics aged > or =60 years; they were compared with younger patients. The average severity of AWS did not differ between age groups. Daily alcohol intake and frequency of drinking were higher in younger alcoholics, but even when adjustment was made for this, severity of AWS was equal in both age groups. A relationship between severity of AWS and age was not detected.

The course of anxiety, depression and drinking behaviours after completed detoxification in alcoholics with and without comorbid anxiety and depressive disorders.

We studied the associations between comorbid anxiety and depressive disorders in treated alcoholics, the course of current anxiety and depression during the early and late post-detoxification periods, and drinking behaviours after discharge. Lifetime psychiatric comorbidity was assessed in 100 alcoholics using the Composite International Diagnostic Interview (CIDI). Three subgroups defined as group DA (comorbid depressive and anxiety disorders, n = 15), group A (anxiety disorder only, n = 23), and group NO (no comorbid disorder, n = 62) were studied. Beginning 21 +/- 13 days after cessation of drinking, state anxiety (STAI-X1), trait anxiety (STAI-X2) and depression (BDI) were assessed once per week (t1 to t4) and once more 6 months after discharge (t5, n = 68). The severity of psychopathology decreased during the first 4 weeks after detoxification in all subgroups. However, trait anxiety remained at higher levels in both the comorbid subgroups from t1 to t4. In the follow-up sample, 60.5% of the non-comorbid subjects remained abstinent, but only 26.7% of all comorbid patients and only 12.5% of those with comorbid depressive disorder plus severe current trait anxiety or depression at t1. Independent of their comorbidity status, relapsers at t5 had already reported more trait anxiety than abstainers at t1. We conclude that severe trait anxiety persisting after 3 weeks of abstinence, comorbid depressive and/or anxiety disorders, and combinations of these with moderate or severe current anxiety and depressive states represent the greatest risks of relapse and therefore may indicate a treatment need.

Impaired serum cortisol stress response is a predictor of early relapse.

AIMS: to investigate a possible association of cortisol stress response during early abstention with relapse. METHODS: Thirty-six alcohol-dependent males, half of them with a comorbid anxiety disorder, and 15 healthy controls were exposed to a standardized psychosocial stress test. Thirty-one of the patients were assessed for relapse 6 weeks after discharge. RESULTS: The relapsers showed almost no cortisol responses in the stress test. Comorbid anxiety disorder influenced neither stress response nor relapse. CONCLUSIONS: During early abstention from alcohol, reduced stress-responsivity of the hypothalamo-pituitary-adrenocortical axis seems to be connected to early relapse.
