It is known that the metabolism of homocysteine (Hcy) depends on the vitamins B6, B12 and folate, and furthermore that metformin reduces serum vitamin B12 levels. In order to investigate whether metformin treatment affects serum total Hcy (tHcy) levels we performed an open, prospective, randomised study in 60 non-diabetic male patients with cardiovascular(More)
OBJECTIVE To characterize the endocrine and autoimmune disturbances with emphasis on parathyroid dysfunction in patients with 22q11.2 deletion syndrome (22q11.2 DS). Design In this nationwide survey; 59 patients (age 1-54 years) out of 86 invited with a 22q11.2 DS were recruited through all the genetic institutes in Norway. METHODS Data was collected from(More)
Variants in hepatocyte nuclear factor (HNF)-4alpha cause maturity-onset diabetes of the young, type 1 (MODY1) and may also be risk factors for type 2 diabetes. We sequenced the HNF4A gene of 95 MODY3-negative probands from the Norwegian MODY Registry. We found three novel coding variants in exon 8 of HNF4A: G326R, T339I, and W340X. In intron 7, we noted a(More)
We have investigated 31 subjects from five unrelated families with one or more members with cystathionine beta-synthase (CBS) deficiency. On the basis of their CBS genotype, the subjects were grouped as normal (n = 11) or heterozygotes (n = 20). Based on pyridoxine effect in the probands, the heterozygotes were further classified as pyridoxine-responsive (n(More)
OBJECTIVES To study whether the addition of metformin further improves the blood lipid pattern in non-diabetic patients with coronary heart disease already treated with lovastatin, diet and lifestyle advice. DESIGN An open, prospective, randomized study in a university hospital setting. SUBJECTS Sixty non-diabetic male patients previously treated with(More)
PURPOSE The purpose of this study was twofold: (1) to measure the radiation exposure to family members of out-patients with thyrotoxicosis treated with radioiodine, 131I, using the recommendations from the European Commission (EC) guidance and age-specific periods for behaviour restrictions; (2) to use the results to identify necessary restrictions to(More)
Cystathionine β-synthase (CBS) deficiency is an autosomal recessive disorder which results in extremely elevated levels of total plasma homocysteine (tHcy) and high risk of thromboembolic events. About half of all patients diagnosed with CBS deficiency respond to pyridoxine treatment with a significant lowering of tHcy levels. We examined 12 CBS-deficient(More)
Clinical and laboratory endocrine variables in 29 adult institutionalized patients with Down's syndrome were compared with those of matched controls consisting of other mentally retarded patients from the same institution. Of the clinical variables, testes volume and body height were significantly lower in patients with Down's syndrome than in control(More)
OBJECTIVE The aims of the study were to examine tooth and enamel disturbances in individuals with 22q11.2 deletion syndrome and to analyze associations with medical conditions, birth characteristics and blood values of calcium and PTH. MATERIALS AND METHODS Fifty individuals participated in the study (27 females, median age 10 years, range 1.5-44).(More)
