- Objectives: To assess effects of GH replacement therapy on cardiac structure and function, exercise capacity as well as serum lipids in elderly patients with GH deficiency (GHD). Patients and methods: Thirty-one patients (six females, 25 males), aged 60–79 years (mean 68 years) with GHD on stable cortisone and thyroxine substitution were studied. All men with gonadotropin deficiency had testosterone and one woman had oestrogen replacement. They were randomized in a double-blind manner to GH or placebo treatment for 6 months, followed by another 12 months GH (Humatrope, Eli Lilly & Co, Uppsala, Sweden). GH dose was 0·017 mg/kg/week for 1 month and then 0·033 mg/kg/week divided into daily subcutaneous injections at bedtime. Echocardiography, exercise capacity tests and serum lipid measurements were performed at 0, 6, 12 and 18 months. Results: During the 6-month placebo-controlled period there were no significant changes in the placebo group, but in the GH-treated group there was a significant increase in IGF-I to normal levels for age, with median IGF-I from 6·9 to 18·5 nmol/l, increase in resting heart rate and maximal working capacity. During the open GH study, IGF-I increased from 8·7 to 19·2 nmol/l at 6 months and 18·8 nmol/l at 12 months (P ≤ 0·001). At 6 months, in the open GH study group, a minor decrease in aortic outflow tract integral (VTI) from 21·8 to 20·7 cm (P = 0·031) and an increase in heart rate at rest from 63 to 67 bpm (P = 0·017), heart rate at maximum exercise from 138 to 144 bpm (P = 0·005) and maximum load at exercise from 142 to 151 Watts (P = 0·014) were seen. These changes were temporary and returned at 12 months with no significant difference from baseline values. Left ventricular dimensions and blood pressure showed no significant changes. At 6 months, in the open GH study group, there was a significant decrease in serum low-density lipoprotein (LDL) cholesterol from 3·7 to 3·4 mmol/l (P = 0·006), a decrease in LDL/HDL ratio from 3·4 to 3·1 (P = 0·036) and a decrease in serum total cholesterol from 5·6 to 5·3 mmol/l (P = 0·036). At 12 months, serum lipids showed same changes with a significant decrease in serum LDL cholesterol (P = 0·0008), in LDL/HDL ratio (P = 0·0005) and in serum total cholesterol (P = 0·049). Serum HDL cholesterol showed no significant change at 6 months, at 12 months a significant increase was seen from 1·2 to 1·4 mmol/l (P = 0·007). There were no significant changes in serum triglycerides. Conclusions: GH substitution to elderly patients with GHD caused only a transient increase in heart rate. At the end of the 12 months there were no significant changes on cardiac noninvasive structural and functional parameters. Maximal working capacity transiently improved. Thus, the therapy was safe without negative effects on cardiac structural and functional noninvasive parameters. Lipid profiles improved with reduction of serum LDL cholesterol accompanied by significant improvement of LDL/HDL ratio and serum HDL cholesterol after 12 months treatment.

- PURPOSE: To assess the occurrence and pattern of adverse drug reactions as a cause for acute hospital admission.METHODS: In 681 randomly selected patients, acutely admitted to a clinic of internal medicine at a Swedish university hospital, information was collected from their medical records about current symptoms and use of drugs, previous diseases and the results of medical investigations and tests. In addition, a standardized interview according to a questionnaire was carried out. A group of experts in clinical pharmacology assessed the data obtained from the patients' case records and the results of the interviews, and then, according to WHO criteria, judged the probability that an adverse drug reaction could have caused or contributed to the actual admission to hospital.RESULTS: Out of the 681 cases included, 94 (13.8%) had symptoms and signs that were judged as drug-related and that had caused or contributed to the admission. Eighty-two patients (12.0%) had altogether 99 symptoms that were classified as adverse drug reactions. Of these, 91% were type A reactions. The relationship between the medication and the reaction was judged certain in eight, probable in 17, and possible in 74 cases. The most common adverse drug reactions were cardiovascular (36.3%). Twelve patients (1.8%) had symptoms indicating intoxications.CONCLUSIONS: The prevalence of drug-related problems causing or contributing to admission to a clinic of internal medicine is high and is dominated by type A reactions, i.e. reactions in principle predictable and preventable. This implies a possibility to increase drug safety by preventive measures.

- OBJECTIVE: Our aim was to test the hypothesis that a combination of markers for Type 1 diabetes (glutamate decarboxylase and IA-2 autoantibodies) and for Type 2 diabetes [oral glucose tolerance test (OGTT) and body mass index (BMI)], would predict clinical diabetes in a regional population. DESIGN: A population-based follow-up cohort study. SETTING: Participants visited the primary health care centre in Lycksele, Sweden in 1988-92. PARTICIPANTS: A cohort of 2278 subjects (M/F 1149/1129) who were studied at follow-up in 1998. At base line there were 2314 subjects (M/F 1167/1147) who participated in the Västerbotten Intervention Program on their birthday when turning either 30, 40, 50 or 60 years of age. Main outcome measurements. A clinically diagnosed diabetes at follow-up when the medical records were reviewed for diagnosis of diabetes. At base line, the participants were subjected to a standard OGTT and their BMI determined along with the autoantibodies. RESULTS: At follow-up, 42/2278 (1.8%, 95% CI 1.2-2.3) (M/F 23/19) had developed diabetes: 41 subjects were clinically classified with Type 2 and one with Type 1 diabetes. There was no significant relation between autoantibody levels at base line and diabetes at follow-up. Stepwise multiple logistic regression showed that the odds ratio for developing diabetes was 10.8 (95% CI 6.3-18.9) in subjects in the fourth quartile of BMI (BMI > 27) compared with 7.8 (95% CI 4.8-12.6) in the fourth quartile of 2-h plasma glucose (>7.5 mmol L(-1)) and 7.2 (95% CI 4.8-11.4) in the fourth quartile of the fasting plasma glucose (>5.6 mmol L(-1)). CONCLUSION: Islet cell autoantibodies did not predict diabetes at follow-up. BMI measured at base line was as effective as 2-h plasma glucose and fasting plasma glucose to predict diabetes in this adult population.
