Abstract
A large proportion of patients with severe obesity remain with left ventricular (LV) dysfunction after bariatric surgery. We assessed whether preoperative evaluation by echocardiography and inflammatory proteins can identify this high-risk group. In the Bariatric Surgery on the West Coast of Norway study, 75 patients (44 ± 10 years, body mass index [BMI] 41.5 ± 4.7 kg/m2) were prospectively evaluated by echocardiography and inflammatory proteins (high-sensitivity C-reactive protein [hsCRP], serum amyloid A [SAA] and calprotectin) before and one year after Roux-en-Y gastric bypass surgery. LV mechanics was assessed by the midwall shortening (MWS) and global longitudinal strain (GLS). Bariatric surgery improved BMI and GLS, and lowered hsCRP, calprotectin and SAA (p < 0.05). MWS remained unchanged and 35% of patients had impaired MWS at 1-year follow-up. A preoperative risk index including sex, hypertension, ejection fraction (EF) and high hsCRP (index 1) or SAA (index 2) predicted low 1-year MWS with 81% sensitivity/71% specificity (index 1), and 77% sensitivity/77% specificity (index 2) in ROC analyses (AUC 0.80 and 0.79, p < 0.001). Among individuals with severe obesity, women and patients with hypertension, increased serum levels of inflammatory proteins and reduced EF are at high risk of impaired LV midwall mechanics 1 year after bariatric surgery.ClinicalTrials.gov identifier NCT01533142 February 15, 2012.

Abstract
Background: Aortic valve sclerosis (AVS), mitral valve sclerosis (MVS), remodeling of major arteries, and increased pericardial fat are associated with subclinical atherosclerosis. We assessed these markers of atherosclerosis in severely obese patients before and 1 year after bariatric surgery. Methods: Eighty-seven severely obese patients (43 ± 10 years, preoperative body mass index [BMI] 41.8 ± 5 kg/m2) underwent echocardiography before and 1 year after Roux-en-Y bypass surgery in the FatWest (Bariatric Surgery on the West Coast of Norway) study. We measured the end-diastolic aortic wall thickness (AWT), pericardial fat thickness at the right ventricular free wall, and AVS/MVS based on combined aortic leaflet thickness and hyperechoic valve lesions. Results: Postoperatively, patients experienced a reduction of 12.9 ± 3.9 kg/m2 in BMI, 0.5 ± 1.9 mm in AWT, 2.6 ± 2.3 mm in pericardial fat, and 45%/53% in AVS/MVS (p < 0.05). In multivariate regression analyses with adjustment for clinical and hemodynamic variables, less pericardial fat reduction was associated with male sex and higher 1-year blood pressure and BMI, and less AWT-reduction with higher age and 1-year BMI (p < 0.05). Persistent AVS and MVS were related to higher 1-year BMI and more advanced valve sclerosis preoperatively (p < 0.05). Conclusions: Markers of subclinical atherosclerosis decreases significantly 1 year after bariatric surgery, particularly in younger patients that achieve a BMI < 28 kg/m2.

Abstract
Aims Patients with severe obesity are predisposed to left ventricular (LV) hypertrophy, increased myocardial oxygen demand, and impaired myocardial mechanics. Bariatric surgery leads to rapid weight loss and improves cardiovascular risk profile. The present prospective study assesses whether LV wall mechanics improve 1 year after bariatric surgery. Methods and results Ninety-four severely obese patients [43 ± 10 years, 71% women, body mass index (BMI) 41.8 ± 4.9 kg/m2, 57% with hypertension] underwent echocardiography before, 6 months and 1 year after gastric bypass surgery in the FatWest (Bariatric Surgery on the West Coast of Norway) study. We assessed LV mechanics by midwall shortening (MWS) and global longitudinal strain (GLS), LV power/mass as 0.222 × cardiac output × mean blood pressure (BP)/LV mass, and myocardial oxygen demand as the LV mass-wall stress-heart rate product. Surgery induced a significant reduction in BMI, heart rate, and BP (P < 0.001). Prevalence of LV hypertrophy fell from 35% to 19% 1 year after surgery (P < 0.001). The absolute value of GLS improved by—4.6% (i.e. 29% increase in GLS) while LV ejection fraction, MWS, and LV power/mass remained unchanged. In multivariate regression analyses, 1 year improvement in GLS was predicted by lower preoperative GLS, larger mean BP, and BMI reduction (all P < 0.05). Low 1-year MWS was associated with female sex, preoperative hypertension, and higher 1-year LV relative wall thickness and myocardial oxygen demand (all P < 0.001). Conclusion In severely obese patients, LV longitudinal function is largely recovered one year after bariatric surgery due to reduced afterload. LV midwall mechanics does not improve, particularly in women and patients with persistent LV geometric abnormalities. ClinicalTrials.gov identifier NCT01533142, 15 February 2012.

Abstract
BACKGROUND Whereas the adverse effects of severe iodine deficiency during pregnancy are well documented, the effects of mild-to-moderate deficiency are not well established. OBJECTIVES We aimed to explore whether iodine nutrition and timing of iodine supplement initiation are associated with thyroid function in pregnant and postpartum women. METHODS In this cohort study, 137 pregnant women were enrolled and followed up at gestational weeks (GWs) 18 and 36, and 3 and 6 mo postpartum. Thyroid function tests [thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4)], urinary iodine and creatinine concentration (UIC:Cr), and iodine intake (including iodine supplement use) were measured at each time point. The associations between thyroid hormone concentrations and UIC:Cr, iodine intakes, and iodine supplement use were estimated using multiple generalized estimating equation models. RESULTS The median UIC at GW18 was 94 μg/L, indicating mild-to-moderate iodine deficiency. UIC:Cr (β; 95% CI) per 100 μg/g was negatively associated with fT3 (-0.191; -0.331, -0.051) and fT4 (-0.756; -1.372, -0.141) concentrations. Iodine intake (β; 95% CI) per 100 μg/d was positively associated with TSH (0.099; 0.022, 0.177), and negatively associated with fT3 (-0.084; -0.0141, -0.027) and fT4 (-0.390; -0.599, -0.182) concentrations. Compared with no use of supplement, those initiating an iodine-containing supplement prepregnancy and continuing through pregnancy had lower TSH (estimated means) (1.35 compared with 1.68 mIU/L, P = 0.021), and higher fT3 (4.48 compared with 4.28 pmol/L, P = 0.035) and fT4 (15.2 compared with 14.4 pmol/L, P = 0.024) concentrations. CONCLUSIONS Lower iodine availability during pregnancy and postpartum was associated with lower TSH, and higher fT3 and fT4 concentrations. The use of an iodine-containing supplement that was initiated prepregnancy and continuing through pregnancy was associated with lower TSH, and higher fT3 and fT4 concentrations, which may suggest improved thyroid function. These findings support the notion that optimization of iodine intake should start before pregnancy.This trial was registered at clinicaltrials.gov as NCT02610959.

Abstract
BACKGROUND AND AIMS Increased myocardial oxygen (O2) demand carries higher cardiovascular risk in hypertension. We hypothesized that myocardial O2 demand is increased in severe obesity and linked to early left ventricular (LV) dysfunction. METHODS AND RESULTS Baseline data from 106 severely obese subjects referred for gastric bypass surgery (42 ± 11 years, 74% women, body mass index [BMI] 41.9 ± 4.8 kg/m2, 32% with hypertension) in the prospective FatWest (Bariatric Surgery on the West Coast of Norway) study was used. LV systolic function was assessed by biplane ejection fraction (EF), midwall shortening (MWS) and endocardial global longitudinal strain (GLS), and LV diastolic function by mitral annular early diastolic velocity (e'). Myocardial O2 demand was estimated from the LV mass-wall stress-heart rate product (high if > 1.62 × 106/2.29 × 106 g kdyne/cm2 bpm in women/men). High myocardial O2 demand was found in 33% and associated with higher BMI and high prevalence of low GLS (65%) and low MWS (63%) despite normal EF. In ROC analyses, higher myocardial O2 demand discriminated between patients with low vs. normal MWS and GLS (area under curve 0.71 and 0.63, p < 0.05). In successive multiple regression analyses, higher myocardial O2 demand was associated with lower LV MWS, GLS and average e', respectively, independent of age, gender, BMI, pulse pressure, diabetes mellitus, and EF (all p < 0.05). CONCLUSION In obese patients without known heart disease and with normal EF referred for bariatric surgery, high myocardial O2 demand is associated with lower myocardial function whether assessed by GLS or MWS independent of confounders.

Abstract
Circulating branched-chain amino acids (BCAAs) associate with insulin resistance and type 2 diabetes. 3-Hydroxyisobutyrate (3-HIB) is a catabolic intermediate of the BCAA valine. In this study, we show that in a cohort of 4,942 men and women, circulating 3-HIB is elevated according to levels of hyperglycemia and established type 2 diabetes. In complementary cohorts with measures of insulin resistance, we found positive correlates for circulating 3-HIB concentrations with HOMA2 of insulin resistance, as well as a transient increase in 3-HIB followed by a marked decrease after bariatric surgery and weight loss. During differentiation, both white and brown adipocytes upregulate BCAA utilization and release increasing amounts of 3-HIB. Knockdown of the 3-HIB-forming enzyme 3-hydroxyisobutyryl-CoA hydrolase decreases release of 3-HIB and lipid accumulation in both cell types. Conversely, addition of 3-HIB to white and brown adipocyte cultures increases fatty acid uptake and modulated insulin-stimulated glucose uptake in a time-dependent manner. Finally, 3-HIB treatment decreases mitochondrial oxygen consumption and generation of reactive oxygen species in white adipocytes, while increasing these measures in brown adipocytes. Our data establish 3-HIB as a novel adipocyte-derived regulator of adipocyte subtype-specific functions strongly linked to obesity, insulin resistance, and type 2 diabetes.

Abstract
BACKGROUND Necrotizing soft tissue infections (NSTIs) are rare but carry a high morbidity and mortality. The multicenter INFECT project aims to improve the understanding of the pathogenesis, clinical characteristics, diagnosis, and prognosis of NSTIs. This article describes the study outline and statistical analyses that will be used. METHODS Within the framework of INFECT project, patients with NSTI at 5 Scandinavian hospitals are enrolled in a prospective observational cohort study. The goal is to evaluate outcome and characteristics for patients with NSTI and diabetes compared to patients with NSTI without diabetes. The primary outcome is mortality at 90 days after inclusion. Secondary outcomes include days alive and out of ICU and hospital, SAPS II, SOFA score, infectious etiology, amputation, affected body area, and renal replacement therapy. Comparison in mortality between patients with diabetes type 1 and 2 as well as between insulin-treated and non-insulin-treated diabetes patients will be made. Clinical data for diabetic patients with NSTI will be reported. CONCLUSION The study will provide important data on patients with NSTI and diabetes.

Abstract
BACKGROUND Early detection of autoimmune Addison's disease (AAD) is important as delay in diagnosis may result in a life-threatening adrenal crisis and death. The classical clinical picture of untreated AAD is well-described, but methodical investigations are scarce. OBJECTIVE Perform a retrospective audit of patient records with the aim of identifying biochemical markers for early diagnosis of AAD. MATERIAL AND METHODS A multicentre retrospective study including 272 patients diagnosed with AAD at hospitals in Norway and Sweden during 1978-2016. Scrutiny of medical records provided patient data and laboratory values. RESULTS Low sodium occurred in 207 of 247 (84%), but only one-third had elevated potassium. Other common nonendocrine tests were largely normal. TSH was elevated in 79 of 153 patients, and hypoglycaemia was found in 10%. Thirty-three per cent were diagnosed subsequent to adrenal crisis, in whom electrolyte disturbances were significantly more pronounced (P < 0.001). Serum cortisol was consistently decreased (median 62 nmol L-1 [1-668]) and significantly lower in individuals with adrenal crisis (38 nmol L-1 [2-442]) than in those without (81 nmol L-1 [1-668], P < 0.001). CONCLUSION The most consistent biochemical finding of untreated AAD was low sodium independent of the degree of glucocorticoid deficiency. Half of the patients had elevated TSH levels. Only a minority presented with marked hyperkalaemia or other nonhormonal abnormalities. Thus, unexplained low sodium and/or elevated TSH should prompt consideration of an undiagnosed AAD, and on clinical suspicion bring about assay of cortisol and ACTH. Presence of 21-hydroxylase autoantibodies confirms autoimmune aetiology. Anticipating additional abnormalities in routine blood tests may delay diagnosis.

Abstract
AIMS Heterozygous mutations in hepatocyte nuclear factor-1A (HNF1A) cause maturity-onset diabetes of the young type 3 (MODY3). Our aim was to compare two families with suspected dominantly inherited diabetes and a new HNF1A variant of unknown clinical significance. METHODS The HNF1A gene was sequenced in two independently recruited families from the Norwegian MODY Registry. Both familes were phenotyped clinically and biochemically. Microsatellite markers around and within the HNF1A locus were used for haplotyping. Chromosomal linkage analysis was performed in one family, and whole-exome sequencing was undertaken in two affected family members from each family. Transactivation activity, DNA binding and nuclear localization of wild type and mutant HNF-1A were assessed. RESULTS The novel HNF1A variant c.539C>T (p.Ala180Val) was found in both families. The variant fully co-segregated with diabetes in one family. In the other family, two subjects with diabetes mellitus and one with normal glucose levels were homozygous variant carriers. Chromosomal linkage of diabetes to the HNF1A locus or to other genomic regions could not be established. The protein functional studies did not reveal significant differences between wild type and variant HNF-1A. In each family, whole-exome sequencing failed to identify any other variant that could explain the disease. CONCLUSIONS The HNF1A variant p.Ala180Val does not seem to cause MODY3, although it may confer risk for type 2 diabetes mellitus. Our data demonstrate challenges in causality evaluation of rare variants detected in known diabetes genes.

Abstract
CONTEXT Autoimmune polyendocrine syndrome type 1 (APS1) is a childhood-onset monogenic disease defined by the presence of two of the three major components: hypoparathyroidism, primary adrenocortical insufficiency, and chronic mucocutaneous candidiasis (CMC). Information on longitudinal follow-up of APS1 is sparse. OBJECTIVE To describe the phenotypes of APS1 and correlate the clinical features with autoantibody profiles and autoimmune regulator (AIRE) mutations during extended follow-up (1996-2016). PATIENTS All known Norwegian patients with APS1. RESULTS Fifty-two patients from 34 families were identified. The majority presented with one of the major disease components during childhood. Enamel hypoplasia, hypoparathyroidism, and CMC were the most frequent components. With age, most patients presented three to five disease manifestations, although some had milder phenotypes diagnosed in adulthood. Fifteen of the patients died during follow-up (median age at death, 34 years) or were deceased siblings with a high probability of undisclosed APS1. All except three had interferon-ω) autoantibodies, and all had organ-specific autoantibodies. The most common AIRE mutation was c.967_979del13, found in homozygosity in 15 patients. A mild phenotype was associated with the splice mutation c.879+1G>A. Primary adrenocortical insufficiency and type 1 diabetes were associated with protective human leucocyte antigen genotypes. CONCLUSIONS Multiple presumable autoimmune manifestations, in particular hypoparathyroidism, CMC, and enamel hypoplasia, should prompt further diagnostic workup using autoantibody analyses (eg, interferon-ω) and AIRE sequencing to reveal APS1, even in adults. Treatment is complicated, and mortality is high. Structured follow-up should be performed in a specialized center.

Abstract
OBJECTIVE The epidemiology of hypoparathyroidism (HP) is largely unknown. We aimed to determine prevalence, etiologies, health related quality of life (HRQOL) and treatment pattern of HP. METHODS Patients with HP and 22q11 deletion syndrome (DiGeorge syndrome) were identified in electronic hospital registries. All identified patients were invited to participate in a survey. Among patients who responded, HRQOL was determined by Short Form 36 and Hospital Anxiety and Depression scale. Autoantibodies were measured and candidate genes (CaSR, AIRE, GATA3, and 22q11-deletion) were sequenced for classification of etiology. RESULTS We identified 522 patients (511 alive) and estimated overall prevalence at 102 per million divided among postsurgical HP (64 per million), nonsurgical HP (30 per million), and pseudo-HP (8 per million). Nonsurgical HP comprised autosomal dominant hypocalcemia (21%), autoimmune polyendocrine syndrome type 1 (17%), DiGeorge/22q11 deletion syndrome (15%), idiopathic HP (44%), and others (4%). Among the 283 respondents (median age, 53 years [range, 9-89], 75% females), seven formerly classified as idiopathic were reclassified after genetic and immunological analyses, whereas 26 (37% of nonsurgical HP) remained idiopathic. Most were treated with vitamin D (94%) and calcium (70%), and 10 received PTH. HP patients scored significantly worse than the normative population on Short Form 36 and Hospital Anxiety and Depression scale; patients with postsurgical scored worse than those with nonsurgical HP and pseudo-HP, especially on physical health. CONCLUSIONS We found higher prevalence of nonsurgical HP in Norway than reported elsewhere. Genetic testing and autoimmunity screening of idiopathic HP identified a specific cause in 21%. Further research is necessary to unravel the causes of idiopathic HP and to improve the reduced HRQOL reported by HP patients.

Abstract
AIMS Gastrointestinal symptoms such as pain, bloating, nausea and vomiting are more frequent in pre-diabetic states as well as established diabetes, compared to healthy individuals. The mechanisms behind these symptoms are multi-factorial and complex. Furthermore, the effect of isolated hyperinsulinaemia on visceral and peripheral sensory function is poorly understood. Thus, the current study aimed to evaluate effects of acute hyperinsulinaemia on sensory function in healthy adults. METHODS The sensitivity to electrical oesophageal and median nerve stimulation was assessed in 15 healthy volunteers together with recording of evoked brain potentials. All subjects were studied both fasting and using a euglycaemic hyperinsulinaemic clamp. RESULTS There was on average a 15% increased sensitivity to oesophageal electrical stimulation during hyperinsulinaemia compared to fasting state (P<0.05), but the sensation after median nerve stimulation remained stable (P=0.58). No significant changes in latencies and amplitudes of evoked brain potentials were observed after oesophageal or median nerve stimulation (all P>0.05). CONCLUSIONS This study suggests that acute isolated hyperinsulinaemia increases visceral sensitivity, but does not influence the somatic sensory function. The lack of changes in the evoked brain potentials may indicate that hyperinsulinaemia affects the visceral sensory system at a peripheral level. Our result suggests distinct functions of insulin in the various parts of the nervous system, and yields further clues to the significance of insulin as a satiety signal.

Abstract
BACKGROUND/AIMS Autosomal dominant hypocalcaemia (ADH) is caused by activating mutations in the calcium- sensing receptor (CASR). We aimed to describe the phenotypic variation within a large family with ADH, especially kidney and cerebral basal ganglia calcifications. METHODS Fifteen related subjects carrying the CASR mutation T151M participated in a cross-sectional study of calcium homeostasis, renal ultrasonography, cerebral CT, bone mineral density, and health-related quality of life (HRQoL). RESULTS Eight subjects had received vitamin D treatment (mean duration 15.3 years; range 11-20 years). Urinary calcium excretion was elevated in 5/8 vitamin-D-treated and in 3/7 untreated subjects. Serum magnesium, calcium and parathyroid hormone remained at the lower reference limit or below. Renal calcifications were found in 12 of 14 (86%) and basal ganglia calcifications in 5 of 11 (46%) subjects, independently of vitamin D therapy. The glomerular filtration rate was moderately reduced in 3 subjects. Mean bone mineral density and bone markers were normal. HRQoL was impaired in the vitamin-D-treated group despite correction of the hypocalcaemia. CONCLUSIONS The impact of the CASR mutation on calcium homeostasis varied greatly. Kidney and basal ganglia calcifications are common in ADH independently of vitamin D treatment, which, however, increases urinary calcium excretion and may promote urolithiasis.

Abstract
BACKGROUND The 5,10-methylenetetrahydrofolate reductase gene (MTHFR) 677C-->T polymorphism modifies the risk of coronary artery disease and colon cancer and is related to plasma concentrations of total homocysteine (tHcy). Riboflavin status modifies the metabolic effect of the polymorphism, and thyroid hormones increase the synthesis of flavin cofactors. OBJECTIVE The aim of the study was to investigate the phenotypic expression of the MTHFR 677C-->T polymorphism in terms of plasma tHcy concentrations in patients with thyroid dysfunction. DESIGN The study population consisted of 182 patients with hyperthyroidism. We studied plasma tHcy in relation to MTHFR genotype, riboflavin, and folate before and during 6 mo of treatment with antithyroid drugs. RESULTS Before treatment, tHcy was higher in patients with the mutant enzyme than in those with the wild-type enzyme. A genotype effect was observed only at low riboflavin or folate concentrations (P </= 0.05). During treatment, concentrations of flavin cofactors in plasma decreased (P < 0.001), and tHcy increased (P < 0.001). The overall tHcy increase was greatest in patients with the T allele, particularly at low riboflavin concentrations (P = 0.004). CONCLUSION Thyroid status affects the phenotypic expression of the MTHFR 677C-->T polymorphism, possibly by modifying the availability of flavin cofactors.

Abstract
OBJECTIVES To investigate plasma total homocysteine levels and its relation to B-vitamins and smoking in Graves' disease before and after antithyroid therapy. DESIGN A longitudinal study taking place at four hospitals in Norway. METHODS AND SUBJECTS Plasma total homocysteine, serum folate, serum cobalamin and riboflavin, flavin mononucleotide and flavin adenine dinucleotide in plasma were investigated in 182 patients with hyperthyroidism before treatment. The same parameters were reinvestigated in 112 of these patients after attaining euthyroid state. RESULTS In hyperthyroidism, plasma total homocysteine was low, and inversely related to folate, cobalamin and riboflavin, and positively related to serum creatinine and age. Following antithyroid therapy, total homocysteine increased and the concentration of folate, cobalamin, riboflavin, flavin mononucleotide and flavin adenine dinucleotide decreased significantly. The most pronounced reduction (35%) was observed for flavin mononucleotide. In the hyperthyroid state, smokers had lower levels of folate and flavin mononucleotide than non-smokers. After restoration of euthyroidism, both folate and riboflavin were significantly lower in smokers than non-smokers. Plasma total homocysteine increased according to decreasing quartiles of B-vitamins. For riboflavin, this relation was confined to smokers. CONCLUSION Plasma total homocysteine changes according to thyroid status. These changes may be partly attributable to altered folate, cobalamin but also riboflavin status, particularly in smokers.

Abstract
The physiological role of dehydroepiandrosterone (DHEA) is not well understood, but studies suggest positive effects on subjective health and bone metabolism. We have conducted a clinical trial with DHEA replacement in adrenal failure with the primary aim of evaluating effects on subjective health status and sexuality. Thirty-nine women with adrenal failure were randomized to 9 months of treatment with 25 mg DHEA (n = 19) or placebo (n = 20). Treatment effects were assessed by validated questionnaires of subjective health and sexuality. DHEA replacement yielded a wide variation of effects on the subjective health scales, which were not different from the effects of placebo. Almost all patients receiving DHEA obtained normal androgen levels. Eighty-nine percent of the patients receiving DHEA experienced side-effects, in particular increased sweat odor and scalp itching. DHEA replacement did not significantly change the levels of blood lipids, IGF-I, and markers of bone metabolism. In conclusion, we do not find evidence of beneficial effects of DHEA on subjective health status and sexuality in adrenal failure. However, DHEA may be beneficial for subgroups of patients with adrenal failure, but these remain to be identified. Premenopausal androgen levels can be restored with 25 mg DHEA daily in most female patients, but side-effects are frequent.

Abstract
Autoimmune destruction of the adrenal cortex is the most common cause of primary adrenocortical insufficiency (Addison's disease) in industrialized countries. We have investigated a large Norwegian cohort of patients with Addison's disease in terms of clinical manifestations, autoantibodies, and human leukocyte antigen (HLA) class II haplotypes. The study comprised 94 patients (54 females) of ages 6-85 yr (mean 45 yr) with, either isolated Addison's disease or part of autoimmune polyendocrine syndrome type II. Among those diagnosed before the age of thirty, 53% were men, while among those diagnosed at 30 or above, 30% were men. Altogether 77 (82%) of the 94 patients had autoantibodies against 21-hydroxylase (21OH). Thirty-eight of the 40 patients with disease duration 5 yr or less had such autoantibodies. This frequency fell to 60% among patients with a disease duration greater than 35 yr. Five women had gonadal failure. This failure correlated with antibodies against side-chain cleavage enzyme (P = 0.03). Antibodies against glutamic acid decarboxylase and IA2 correlated with the presence of type 1 diabetes (P < 0.005 and P = 0.003, respectively). The frequency of the HLA DRB1*03-DQA1*05-DQB1*02 (DR3-DQ2) and DRB1*04-DQA1*03-DQB1*0302 (DR4-DQ8) haplotypes were positively correlated to Addison's disease, whereas the DRB1*01-DQA1*0101-DQB1*0501 (DR1-DQ5) haplotype was negatively correlated. In addition, the DRB1*04 subtype DRB1*0404 was increased among Addison patients relative to controls. We verify that autoimmunity is the main cause of Addison's disease in our cohort. In younger patients, the disease is equally common in men and women. Measurement of autoantibodies against 21OH is a valuable tool in establishing the etiological diagnosis, especially in patients with a short disease duration. Addison's disease is associated with the DR3-DQ2 and DR4 (0404)-DQ8 haplotypes. A particularly high risk for disease development is observed when these occur in a heterozygous combination (DR3-DQ2/DR4-DQ8).

Abstract
Hypothyroidism is associated with increased cardiovascular morbidity, which cannot be fully explained by the atherogenic lipid profile observed in these patients. We have previously found elevated levels of the cardiovascular risk factor, plasma total homocysteine (tHcy), in hypothyroidism. We conducted a longitudinal study on 17 patients who had undergone total thyroidectomy for thyroid cancer. During 6 weeks of discontinued T4 substitution before radioscintigraphy (phase I), they attained a hypothyroid state, which was reversed by resupplementation (phase II). Plasma tHcy, serum creatinine, serum and red blood cell folate, serum cobalamin, and serum cholesterol were determined at 2-week intervals throughout phases I and II. There was a progressive and parallel increase in tHcy (mean, 27%), serum creatinine (37%), and serum cholesterol (100%) during phase I, and these values returned to the original level within 4-6 weeks after reinitiating T4 therapy. Serum and red blood cell folate levels showed only minor, but statistically significant, changes. In a bivariate model, serum creatinine and serum cholesterol were strongly associated with the changes observed in tHcy during short term hypothyroidism. In conclusion, we found a transient increase in both plasma tHcy and serum cholesterol during short term iatrogenic hypothyroidism, and the tHcy response is probably mainly explained by concurrent changes in renal function. The increase in both plasma tHcy and serum cholesterol may confer increased cardiovascular risk in hypothyroid patients.

Abstract
We found a higher plasma concentration of total homocysteine (tHcy), an independent risk factor for cardiovascular disease, in patients with hypothyroidism (mean, 16.3 micromol/L; 95% confidence interval [CI], 14.7 to 17.9 micromol/L) than in healthy controls (mean, 10.5 micromol/L; 95% CI, 10.1 to 10.9 micromol/L). The tHcy level of hyperthyroid patients did not differ significantly from that of the controls. Serum creatinine was higher in hypothyroid patients and lower in hyperthyroid patients than in controls, whereas serum folate was higher in hyperthyroid patients compared with the two other groups. In multivariate analysis, these differences did not explain the higher tHcy concentration in hypothyroidism. We confirmed the observation of elevated serum cholesterol in hypothyroidism, which together with the hyperhomocysteinemia may contribute to an accelerated atherogenesis in these patients.

Abstract
The authors highlight some aspects of diabetes mellitus that complicate pregnancy. Several complications, e.g. hypoglycaemia, hyperglycaemia and macrosomia are described briefly. Macrosomia can be diagnosed by ultrasound examination, which should be performed every other week from the 24th week of gestation. Accelerated abdominal circumference (> or = 1.2 cm/week) between 32 and 39 weeks and excess thickness of soft tissue over the proximal humerus of the foetus after the 32nd week (> 13 mm at term) may imply development of macrosomia. The elevated risk related to adiposity and poor metabolic control can be avoided by intensive treatment. Intensive metabolic treatment can also reduce the frequency of preeclampsia and polyhydramnion. Ketoacidosis and intrauterine foetal death may be consequences of poor diabetic control. The authors discuss infectious problems, some aspects of treatment, e.g. risk of preterm delivery, dietary treatment and insulin, indications for delivery and various neonatal problems.

Abstract
The authors review various aspects of gestational diabetes, including definition, screening, diagnostic procedures, complications (hypertension, macrosomia), clinical evaluation (ultrasound, non-stress test), treatment (diet, insulin), indications for delivery and neonatal aspects (hypoglycaemia, hypocalcaemia). Complications can be reduced by intensive dietary treatment and insulin. If the gestational diabetes is regulated well the woman can wait for spontaneous birth at term. In the case of pregnant women with less than optimal regulated diabetes, however, or with complications such as hypertension, macrosomia, previous stillbirth, labour can be induced preterm by local administration of prostaglandin or infusion of oxytocin. Physical training and weight reduction should be instituted to avoid later development of type II diabetes mellitus. There is still some uncertainty about different aspects of gestational diabetes.

Abstract
We reviewed the records of seven patients with low serum cobalamin levels that were difficult to interpret in relation to haemoglobin concentrations and clinical symptoms. Myelodysplastic syndrome was diagnosed in four out of five anaemic patients. Three of them had a true vitamin B12 deficiency at the same time. The fifth patient had a non-Hodgkin lymphoma with Coombs-negative autoimmune haemolytic anaemia. Two patients had low cobalamin levels without anaemia. Measurements of plasma homocysteine and serum methylmalonic acid may be useful for diagnosing true vitamin B12 deficiency.
