Amitriptyline and cyclobenzaprine have shown some efficacy in treatment of the generalised pain syndrome, fibromyalgia. The aim of this study was to examine the efficacy of antidepressant dosages of the serotonin re-uptake inhibitor citalopram in fibromyalgia. In a double-blind, placebo-controlled study 22 patients with fibromyalgia were randomized to treatment with citalopram for 4 weeks at a dosage of 20 mg a day while 21 received placebo. After 4 weeks the dosage was increased to 40 mg for a further 4 weeks if the subjects did not report a marked improvement. After the end of treatment (8 weeks) no changes were observed in self-assessment of symptoms, physician's global assessment, tender points, Beck depression score or voluntary muscle strength and no differences were observed between the groups. Citalopram showed no demonstrable effect on this group of pain patients. The strength of the study was sufficient to exclude an effect of citalopram of more than 1 steps of 10 on the categoric scales for pain, fatigue and general condition (95% confidence limit), which indicates that the sample size was sufficiently large.

and both serum and eluate showed large amounts of antibody. The patient remained well at follow up, and a weight loss of 20 kg was maintained with moderate oral doses of diuretics. DiscussionWarm autoimmune haemolytic anaemia is conventionally treated with steroids, to which about 900/o of patients respond.' In nonresponders immunosuppression and splenectomy have been used. Splenectomy is effective in about half the cases,2 so splenic irradiation might be expected to produce a benefit. This, however, was not confirmed in two reports ofits use from the 1950s.3 4 Both of these cases were unusual in showing a persistently negative response on direct Coombs test. Furthermore, splenectomy is most effective with IgG non-complement fixing autoantibodies,' which our patient possessed, and we might expect splenic irradiation to be similar. Such data were not available in the previous two cases.Our patient failed to respond to steroids or azathioprine, but after an uncomplicated course of splenic irradiation the haemoglobin concentration returned to normal despite the continued presence of circulating antibody and a positive response to the direct Coombs test. A delayed response to azathioprine cannot be excluded but the time course and maintained rise without azathioprine make this explanation less likely. Splenic irradiation may thus offer a simple treatment in patients with resistant warm autoimmune haemolytic anaemia in whom splenectomy is contraindicated.We thank Drs Laing, Holt, Bolton, and Key for their help and Professor P Sleight for permission to report the case. Metabolic abnormalities in children of non-insulin dependent diabetic&.Non-insulin dependent diabetes appears to be an inherited condition. A study of young offspring of non-insulin dependent diabetics was conducted to determine whether metabolic abnormalities could be found at a young age before clinical diabetes developed. Thirteenpatientswithnon-insulindependentdiabetes were selected who fulfilled the following criteria: (a) they had a sibling who also had non-insulin dependent diabetes, (b) their spouse was non-diabetic, and (c) the offspring were aged between 12 and 45 years, not diabetic, and available for study. All 32 offspring had a 75 g oral glucose tolerance test, and results in 13 ofthem, one randomly selected from each family, were cowpared with 13 controls of similar age, sex, and weight. The offspring had significantly higher fasting concentrations of glucose, higher proportions of haemoglobin A1, and higher concentrations of insulin, C peptide, and glucagon. After glucose challenge the increases in both glucose and C peptide concentrations were significantly greater in the offspring. These differences were maintained in all 32 offspring when compared with 18 controls of

The objective of this study was to test the efficacy of intravenously administered S-adenosyl-L-methionine (SAMe) in patients with fibromyalgia (FM). Thirty-four out-patients with fibromyalgia symptoms received SAMe 600 mg i.v. or placebo daily for 10 days in a cross-over trial. There was no significant difference in improvement in the primary outcome: tender point change between the two treatment groups. There was a tendency towards statistical significance in favour of SAMe on subjective perception of pain at rest (p = 0.08), pain on movement (p = 0.11), and overall well-being (p = 0.17) and slight improvement only on fatigue, quality of sleep, morning stiffness, and on the Fibromyalgia Impact Questionnaire for pain. No effect could be observed on isokinetic muscle strength, Zerrsen self-assessment questionnaire, and the face scale. No effect of SAMe in patients with FM was found in this short term study.

The chronic effect of the calcium antagonist nitrendipine was investigated on blood pressure (BP), plasma aldosterone concentration (PAC), plasma renin activity (PRA), and serum potassium in six patients with primary aldosteronism, either due to an (unilateral) aldosterone-producing adenoma (APA; n = 3; age, 44 +/- 4 years; PAC, 312 +/- 96 pg/ml; PRA, less than 0.1 ng/l.h; serum potassium, 2.8 +/- 0.3 mmol/l) or to bilateral idiopathic hyperaldosteronism (IHA; n = 3; age, 49 +/- 1 years; PAC, 212 +/- 32 pg/ml; PRA, 0.1 +/- 0.1 ng/l.h; serum potassium, 3.3 +/- 0.2 mmol/l). After withdrawal of antihypertensive medications at least 3 weeks prior to the study, nitrendipine was given orally in a daily dosage of 40 to 60 mg. BP, PAC, PRA, and serum potassium were determined before (see data above) and after 4 weeks of nitrendipine therapy. After 4 weeks, BP was significantly reduced (178 +/- 10 to 165 +/- 6 mmHg systolic, 109 +/- 7 to 101 +/- 6 mmHg diastolic) in three patients with APA and in two with IHA. No significant changes of PAC, PRA, and serum potassium were observed in these patients. However, one patient with clinical characteristics of IHA and a long-term history of diuretic therapy showed a complete normalization of BP, PAC, PRA, and serum potassium, suggesting that the etiology of autonomous hyperaldosteronism in this patient might differ from typical primary aldosteronism. From these findings we conclude that calcium antagonists may be helpful in lowering BP in those patients with primary aldosteronism who develop intolerable side effects under treatment with spironolactone or trilostane.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between chlorpropamide alcohol flushing and non-insulin dependent diabetes remains uncertain. It is known, however, that the frequency of facial flushing with alcohol and the temperature response depend upon both the plasma level of chlorpropamide and the starting facial temperature [10]. We tested 23 young adult non-diabetic subjects with 8 g of ethanol after a dose of chlorpropamide 250 mg twice daily for 2 days or a placebo, in a double blind, cross-over manner. Previously, nine other subjects had participated in a pilot study to assess the safety of the chlorpropamide dose and to ensure that adequate plasma chlorpropamide levels were achieved. No subject was negative for chlorpropamide alcohol flushing, as defined by the following criteria: facial temperature rise of 35% or more of maximum possible rise, observer assessment or subject assessment. In 26 of the total 32 subjects, all three criteria were fulfilled. Thus, among young, healthy non-diabetic adults chlorpropamide alcohol flushing would appear to be a normal phenomenon.
