Association between HLA Class II Alleles/Haplotypes and Genomic Ancestry in Brazilian Patients with Type 1 Diabetes: A Nationwide Exploratory Study.

We aimed to identify HLA-DRB1, -DQA1, and -DQB1 alleles/haplotypes associated with European, African, or Native American genomic ancestry (GA) in admixed Brazilian patients with type 1 diabetes (T1D). This exploratory nationwide study enrolled 1599 participants. GA percentage was inferred using a panel of 46 ancestry informative marker-insertion/deletion. Receiver operating characteristic curve analysis (ROC) was applied to identify HLA class II alleles related to European, African, or Native American GA, and showed significant (p < 0.05) accuracy for identifying HLA risk alleles related to European GA: for DRB1*03:01, the area under the curve was (AUC) 0.533; for DRB1*04:01 AUC = 0.558, for DRB1*04:02 AUC = 0.545. A better accuracy for identifying African GA was observed for the risk allele DRB1*09:01AUC = 0.679 and for the protective alleles DRB1*03:02 AUC = 0.649, DRB1*11:02 AUC = 0.636, and DRB1*15:03 AUC = 0.690. Higher percentage of European GA was observed in patients with risk haplotypes (p < 0.05). African GA percentage was higher in patients with protective haplotypes (p < 0.05). Risk alleles and haplotypes were related to European GA and protective alleles/haplotypes to African GA. Future studies with other ancestry markers are warranted to fill the gap in knowledge regarding the genetic origin of T1D in highly admixed populations such as that found in Brazil.

Adaptation and psychometric assessment of the instrument "Partners of Adults with Type 1 Diabetes Distress Scale" in a Brazilian population.

Objectives: To adapt the instrument "Partners of Adults with Type 1 Diabetes Distress Scale" (Partner-DDS) into Brazilian culture, and to evaluate the psychometric characteristics of the adapted version. Methods: All the cultural adaptation steps of the measure's instruments were followed. The psychometric properties such as reliability (stability by test-retest; internal consistency), and convergent construct validity were performed. Results: Of all 72 partners, 69.4% were male, mean age: 42.69 ± 14.09 years, mean of marriage duration: 14.74 ± 12.41 years, and mean schooling: 11.81 ± 3.91 years.The internal consistency of the instrument (Cronbach Alpha) was 0.90. The intra-class coefficient (stability) was 0.80 (0.72-0.84). The Spearman coefficient (convergent construct validity) between the Partner-DDS scale and the Anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A) was 0.4273 (p < 0.0002). Conclusions: The steps of the instruments' cultural adaptation were appropriately performed. The Brazilian version of the Partner- DDS scale demonstrates reliable psychometric properties for being used in POPWT1D distress evaluation in Brazil. Innovation: The cultural adaptation of Partner-DDS scale into Brazilian Portuguese is a helpful innovation to assess the emotional burden in POPWT1D. This tool could be used to provide education and psychological support for this population.

HLA Genotypes and Type 1 Diabetes and Its Relationship to Reported Race/Skin Color in Their Relatives: A Brazilian Multicenter Study.

We aimed to investigate the relationship between HLA alleles in patients with type 1 diabetes from an admixed population and the reported race/skin color of their relatives. This cross-sectional, multicenter study was conducted in public clinics in nine Brazilian cities and included 662 patients with type 1 diabetes and their relatives. Demographic data for patients and information on the race/skin color and birthplace of their relatives were obtained. Typing of the HLA-DRB1, -DQA1, and -DQB1 genes was performed. Most studied patients reported having a White relative (95.17%), and the most frequently observed allele among them was DRB1*03:01. Increased odds of presenting this allele were found only in those patients who reported having all White relatives. Considering that most of the patients reported having a White relative and that the most frequent observed allele was DRB1*03:01 (probably a European-derived allele), regardless of the race/skin color of their relatives, we conclude that the type 1 diabetes genotype comes probably from European, Caucasian ethnicity. However, future studies with other ancestry markers are needed to fill the knowledge gap regarding the genetic origin of the type 1 diabetes genotype in admixed populations such as the Brazilian.

Emotional burden and care of adults with type 1 diabetes during the COVID-19 pandemic in Brazilian regions.

AIMS: This study investigated the emotional burden in persons with type 1 diabetes (PWT1D) during the COVID-19 pandemic in Brazilian regions and evaluated which COVID-19, sociodemographic/clinical characteristics are related to it. METHODS: In a cross-sectional study, T1D adults completed a web-based survey from May to July 2020. We collected sociodemographic/clinical data, and participants answered COVID-19 related questions. Diabetes burnout was evaluated by Diabetes burnout scale. Type 1 Diabetes scale assessed Diabetes Distress and PHQ-8 measured depressive symptoms. RESULTS: DD and DS levels were similar in all Brazilian regions. DB was higher in Central-West/North/Northeast. Higher DB was associated with females, lower-income, higher HbA1c, and shorter time since T1D diagnosis. Predictors of experiencing higher levels of DD included: difficulty access to safe places to exercise, participants without a partner, male gender, young age, and higher HbA1c. Higher depressive symptoms were associated with difficulty to access diabetes supplies, and higher HbA1c (p < 0.05). CONCLUSIONS: The mean levels of DB, DD, and DS were high in all Brazilian regions. A great number of PWT1D had their diabetes care impaired and relied on family as their main support during the pandemic. The subgroups identified at risk should be prioritized in mental health support.

Cross-national comparison of psychosocial well-being and diabetes outcomes in adults with type 1 diabetes during the COVID-19 pandemic in US, Brazil, and Iran.

BACKGROUND: The COVID-19 pandemic is a global public health emergency, which presents wide-ranging negative impacts on individuals with diabetes. To examine psychosocial well-being and diabetes outcomes in individuals with type 1 diabetes during the COVID-19 pandemic, and investigate how these factors vary in different countries. METHODS: Between April and June 2020 we employed a cross national comparative research study in the United States (US), Brazil, and Iran to collect data from 1788 adults with type 1 diabetes using web-based survey. Study participants answered questions relevant to diabetes distress, diabetes burnout, depressive symptoms, COVID-19 related changes, and socio-demographic characteristics. They also reported their last Hemoglobin A1c (HbA1c) and daily Time-in-Range (TiR) blood glucose. We analyzed data using comparative tests (Chi-square, Kruskal-Wallis and McNemar test), logistic and linear regression adjusted for fixed effects. RESULTS: There were significant changes prior and during the pandemic regarding access to diabetes care, diabetes supplies and medications, healthy food and safe places to exercise in all countries (p < 0.05). Participants in Iran experienced higher levels of diabetes distress (57.1%), diabetes burnout (50%), and depressive symptoms (60.9%), followed by Brazil and US (p < 0.0001). US participants reported better glycemic control (HbA1c = 6.97%, T1R = 69.64%) compared to Brazil (HbA1c = 7.94%, T1R = 51.95%) and Iran (HbA1c = 7.47%, T1R = 51.53%) (p < 0.0001). There were also significant relationships between psychosocial well-being, diabetes outcomes, socio-demographic data, and COVID-19 related challenges in overall sample (p < 0.05). CONCLUSIONS: Regardless of differences among US, Brazil, and Iran, our findings revealed that different countries may experience similar challenges related to the COVID-19 pandemic which can impact negatively diabetes outcomes and psychosocial well-being in individuals with type 1 diabetes. Countries need to consider modifiable variables associated with poor diabetes outcomes and sub optimal psychosocial well-being and target vulnerable population using significant socio-demographic variables.

Fixed 30 mCi 131I-iodine therapy without recombinant human thyroid-stimulating hormone stimulation as an attractive therapeutic alternative in nontoxic nodular goiter.

OBJECTIVE: To analyze outcomes of patients with compressive nontoxic multinodular goiter after 131I-iodine 30 mCi treatment without previous use of recombinant human thyroid-stimulating hormone or methimazole. METHODS: We evaluated fixed-dose radioiodine therapy outcomes in patients with nontoxic multinodular goiter who did not accept thyroidectomy as a therapeutic option. Laboratory thyroid function and thyroid volume estimated by ultrasound were assessed before and one year after radioiodine therapy. RESULTS: Twenty euthyroid female patients received 30 mCi of 131I-iodine without recombinant human thyroid-stimulating hormone or methimazole pretreatment. Median thyroid volume and Tc-99m sodium pertechnetate thyroid uptake before radioiodine therapy were 68.05 cm (31.3-295.3) and 0.5% (0.1%-1.2%), respectively. One year after radioiodine therapy, thyroid volume decreased to 55.4 cm (19.8-149.9), and merely 4 patients (20%) developed hypothyroidism. Thyroid volume decreased significantly after radioiodine therapy, presenting a variation of -21.1 cm (-161.3 to -0.8) and -30.61% (-73.88 to -1.02), both with P < 0.0001. Thyroid volume variation was positively correlated with thyroid uptake in Spearman's correlation (r = 0.4730; P = 0.0352). The group satisfied with radioiodine therapy (85%, n = 17) showed a significant reduction in thyroid volume, -25.8 cm (-161.3 to -6.2) and -36.74% (-73.88 to -9.95). The dissatisfied group (15%, n = 3) showed -1.0 cm (-2.0 to -0.8) and -1.67% (-3.38 to -1.02) in thyroid volume, P = 0.0081. Patients that complained about dysphagia presented a lower percentage of thyroid volume decrease after radioiodine therapy, -21.97% (-70.12 to -1.02, P = 0.0430). CONCLUSIONS: A substantial reduction in thyroid volume associated with a low incidence of hypothyroidism and a high satisfaction rate support the use of conventional radioiodine therapy with a fixed dose of 30 mCi. This therapy is an attractive and cheaper therapeutic alternative in selected patients with nontoxic multinodular goiter.

Type 1 diabetes mellitus associated or not with primary hypothyroidism and women's fertility.

The aim of this study is to evaluate the prevalence of infertility and other reproductive parameters in women with type 1 diabetes mellitus (DM1) with and without primary hypothyroidism (PH). This is a cross-sectional study conducted at Division of Endocrinology. We evaluated 110 female, aged over 18 years, 79 had DM1 and 31 had DM1 plus PH. They were interviewed to obtain data on their gynecological and obstetric history; medical charts were reviewed to determine the characteristics of the diseases and to assess clinical/laboratory data. Infertility was defined as 12 months of unprotected sexual intercourse without conception. We used the chi-square and Mann-Whitney's tests, and logistic regression analysis. The prevalence of infertility in the total sample was 24.5%, no differences were found between groups regarding obstetric outcomes and gynecologic variables. Factors associated with infertility were microvascular complication (OR: 11.36; 95% CI: 2.488-52.632; p = .029), polycystic ovary syndrome (OR: 9.80; 95% CI: 2.247-43.478; p = .016), PH (OR: 3.38; 95% CI: 1.078-10.638; p = .047), and older age at onset of DM1 (OR: 1.12; 95% CI: 1.029-1.215; p = .019). The presence of PH in women with DM1 was a predictive factor for infertility. Women with DM1 showed poorer reproductive outcomes compared to the general population.

Glutathione peroxidase 4 functional variant rs713041 modulates the risk for cardiovascular autonomic neuropathy in individuals with type 1 diabetes.

Cardiac autonomic neuropathy is a neglected diabetic chronic complication for which genetic predictors are rarely reported. Oxidative stress is implicated in the pathogenesis of microvascular complications, and glutathione peroxidase 4 is involved in the detoxification of peroxides and of reactive oxygen species. Thus, the association of a functional variant in the gene encoding glutathione peroxidase 4 (rs713041) with this diabetic complication was investigated in 341 individuals with type 1 diabetes evaluated for cardiac autonomic neuropathy status (61.7% women, 34 [27-42] years old; diabetes duration: 21 [15-27] years; HbA1c: 8.3% [7.4-9.4]; as median [interquartile interval]). Cardiac autonomic neuropathy was present in 29% of the participants. There was an inverse association of the minor T allele of rs713041 with cardiac autonomic neuropathy (odds ratio = 0.39; 95% confidence interval = 0.17-0.90; p = 0.0271) after adjustment for potential confounders. The functional glutathione peroxidase 4 variant rs713041 modulated the risk for cardiac autonomic neuropathy in the studied population with type 1 diabetes.

Genetic variants in DNMT1 and the risk of cardiac autonomic neuropathy in women with type 1 diabetes.

AIMS/INTRODUCTION: Epigenetics participate in the pathogenesis of metabolic memory, a situation in which hyperglycemia exerts prolonged deleterious effects even after its normalization. We tested the hypothesis that genetic variants in an epigenetic gene could predispose to diabetes complications. MATERIAL AND METHODS: We assessed the frequency of five single-nucleotide polymorphisms in the gene encoding deoxyribonucleic acid methytransferase 1 (DNMT1; rs8112895, rs7254567, rs11085721, rs17291414 and rs10854076), and their associations with diabetic kidney disease, retinopathy, distal polyneuropathy and autonomic cardiovascular neuropathy in 359 individuals with long-term type 1 diabetes. RESULTS: None of the single-nucleotide polymorphisms studied was significantly associated with the presence of chronic complications in the overall population. However, after sex stratification, the minor allele C of rs11085721 conferred risk for cardiovascular neuropathy in women after adjustment for confounding variables (odds ratio 2.32; 95% confidence interval 1.26-4.33; P = 0.006). CONCLUSIONS: The fact that heterozygous mutations in DNMT1 are associated with hereditary sensory autonomic neuropathy provides plausibility to the present finding. If confirmed in independent samples, it suggests that genetic variants in epigenetic genes might predispose to more or fewer epigenetic changes in the face of similar metabolic derangements triggered by hyperglycemia, constituting the "genetics of epigenetics" for microvascular diabetes complications.

Identification and performance of multiple clinical and laboratorial risk factors for diagnosis of cardiac autonomic neuropathy in type 1 diabetes patients.

PURPOSE: The incidence of cardiac autonomic neuropathy (CAN) in patients with type 1 diabetes (T1D) is frequently underestimated. Individuals with T1D and CAN have an increased mortality risk, mainly from cardiovascular causes. The objectives of the present study were to assess the clinical and laboratory characteristics associated with CAN in patients with T1D and verify the ability of multiple clinical factors to help identify patients with this condition. METHODS: 102 patients with T1D were evaluated for CAN using standardized cardiovascular reflex testing. Clinical characteristics were used to compute a numerical score for CAN diagnosis and a ROC curve elaborated for assessment of the best cutoff to predict CAN. This score was then applied to the second sample of 120 patients. The sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: Prevalence of CAN was around 35% in the first sample of patients and just below 20% in the second sample. Hypertension, total cholesterol, triglycerides, postprandial sweating, diastolic blood pressure, abnormal right and left 10 g monofilament, retinopathy, and nephropathy were considered independent predictors of CAN. The CAN-score cut-off was 16.88. This yielded a sensitivity of 50%, specificity 73.8%, positive predictive value 22.9%, and negative predictive value 90.5%. CONCLUSION: The use of a subset of clinical and laboratory characteristics can be more accessible than the cardiac reflex tests and more accurate than a single isolated characteristic.

Subclinical cardiovascular disease parameters after one year in new users of depot medroxyprogesterone acetate compared to copper-IUD.

PURPOSE: To evaluate markers of cardiovascular disease in women with normal insulin sensitivity who had recently initiated use of depot medroxyprogesterone acetate (DMPA) as a contraceptive. MATERIALS AND METHODS: A prospective, non-randomised, comparative study. Data of 30 women of 18-40 years of age, with normal hyperinsulinaemic-euglycaemic clamp at baseline and body mass index (BMI) < 30, who opted to use DMPA or a copper intrauterine device (IUD) as a contraceptive, were analysed. Serum samples were collected for evaluation of the lipid and hepatic profile, C-reactive protein, TNF-α, interleukin-6, leptin/adiponectin ratio and free fatty acids; body composition was evaluated using DXA, blood pressure and carotid intima-media thickness were measured. Evaluations were performed at baseline and 12 months later. The groups were compared using repeated measures analysis of variance (ANOVA). Significance level was 5%. RESULTS: The mean age of the women in the DMPA and IUD group was 28.7 ± 6.5 and 28.3 ± 5.8 years, respectively; the BMI was 23.0 ± 3.4 and 24.3 ± 2.7 kg/m2, respectively, in the same groups. At 12 months, triglyceride levels were higher in the DMPA group compared to the IUD group and there was an increase in apolipoprotein B-100 in relation to baseline in DMPA group; there were no other difference between the groups. CONCLUSIONS: No clinical cardiovascular effect was found but deterioration in CV markers was observed in the first year of use of DMPA.

Hyperinsulinemic-euglycemic clamp over the first year of use of depot-medroxyprogesterone acetate as a contraceptive.

OBJECTIVE: The literature lacks data on the use of the gold-standard hyperinsulinemic-euglycemic clamp (HEC) technique for the evaluation of insulin resistance (IR) in depot-medroxyprogesterone acetate (DMPA) users. This study assessed carbohydrate metabolism in non-obese users of DMPA using the HEC technique. STUDY DESIGN: A prospective, non-randomized, comparative study conducted at the Family Planning Clinic/Metabolic Unit, University of Campinas, Brazil. Forty-eight women aged 18-39 years underwent HEC: 30 initiating use of DMPA and 18 initiating use of a copper intrauterine device (IUD). Data from 15 women in each group, who completed the follow-up and underwent HEC at12 months, were compared using repeated measures ANOVA. All women were advised to perform aerobic physical exercise for 150 min/week; body composition and total energy intake were evaluated. Main outcome measures were IR defined by M-value <4 mg/kg/min, and blood levels of insulin. Additional outcomes were total cholesterol, HDL-cholesterol, triglycerides, LDL-cholesterol, adipokines and free fatty acids. RESULTS: At 12 months, two women in the DMPA group and none in the IUD group had developed IR. The groups were similar in in M-values and in blood levels of insulin, total cholesterol, HDL-cholesterol, LDL-cholesterol, adipokines or free fatty acids. Triglyceride levels increased in the DMPA group when compared to the IUD group, 80.0 (SD 47.8) versus 61.8 (SD 35.8) mg/dL respectively, (p=.033); and increased the total daily energy intake, 1828.3 (SD 518.9) versus 1300.8 (SD 403.4) kilocalories/24hs, respectively in the same groups, (p=.041). All the DMPA users showing higher insulin sensitivity at 12 months reported performing physical activity regularly. CONCLUSIONS: Changes occurred in carbohydrate metabolism in DMPA users in the first year of use of the method. It is possible that the regular aerobic exercise may exert a beneficial and protective effect against the factors that trigger these changes. IMPLICATIONS STATEMENT: Carbohydrate metabolism undergoes adverse changes in few young non-obese women during the first year of DMPA use and regular aerobic exercise may exert a beneficial and protective effect against these changes.

The impact of ethnicity, educational and economic status on the prescription of insulin therapeutic regimens and on glycemic control in patients with type 1 diabetes. A nationwide study in Brazil.

AIMS: Establish the relationship between demographic, educational and economic status on insulin therapeutic regimens (ITRs) and on glycemic control in patients with type 1 diabetes. METHODS: This was a cross-sectional, multicenter study with 1760 patients conducted between August 2011 and August 2014 in 10 Brazilian cities. RESULTS: Patients were stratified according to ITRs as follows: only NPH insulin (group 1, n=80(4.5%)); only long-acting insulin analogs (group 2, n=6(0.3%)); continuous subcutaneous insulin infusion (CSII) (group 3, n=62(3.5%)); NPH plus regular insulin (group 4, n=710(40.3%)); NPH plus ultra-rapid insulin analogs (group 5, n=259(14.8%)); long-acting insulin analogs plus regular insulin (group 6, n=25(4.4%)) and long-acting plus ultra-rapid insulin analogs (group 7, n=618 (35.1%)). As group A (provided free of charge by the government) we considered groups 1 and 4, and as group B (obtained through lawsuit or out-of-pocket) groups 2, 3 and 7. Multivariate logistic analysis showed that independent variables related to group B were older age, more years of school attendance, higher economic status and ethnicity (Caucasians). The independent variables related to better glycemic control were older age, higher adherence to diet, higher frequency of self-monitoring of blood glucose, more years of school attendance and belonging to group B. CONCLUSIONS: In Brazilian National Health Care System, prescriptions of insulin analogs or CSII are more frequent in Caucasian patients with type 1 diabetes, with higher economic status and more years ofschool attendance. Among these variables years of school attendance was the only one associated with better glycemic control.

Body composition and metabolic profile in adults with vitamin D deficiency / Composição corporal e perfil metabólico na deficiência de vitamina D sérica em adultos

ABSTRACT Objective: To investigate the body composition and metabolic profile in individuals in terms of different concentrations of serum vitamin D, ranging from deficiency to sufficiency. Methods: A cross-sectional study of 106 adults of both genders, who were divided into three groups according to vitamin D levels: deficiency: <20ng/mL; insufficiency: 20-29.9ng/mL; and sufficiency: 30-100ng/mL. Anthropometric evaluation included weight, height, and body circumferences. Fat mass and lean mass were assessed using the Tetrapolar bioelectrical impedance method. Clinical and biochemical evaluations were also carried out. Insulin resistance was estimated using the Homeostasis Model Assessment Insulin index. Results: The analysis showed that the main alterations in individuals in the vitamin D deficiency group were higher triglycerides, very low density lipoprotein - cholesterol, fasting blood glucose, insulin, glycated hemoglobin, body mass index, body fat percentage, lean mass percentage, waist circumference, and Homeostasis Model Assessment Insulin than those of the vitamin D sufficient group (p<0.05). Conclusion: It was found that vitamin D deficiency causes important body composition and metabolic changes, which may lead to diseases such as diabetes Mellitus and metabolic syndrome.

RESUMO Objetivo: Investigar a composição corporal e o perfil metabólico de indivíduos com diferentes concentrações de vitamina D sérica, da deficiência à normalidade. Métodos: Estudo transversal realizado com 106 indivíduos adultos, de ambos os sexos, divididos em três grupos de acordo com as concentrações de vitamina D: deficiência: <20ng/mL; insuficiência: 20-29,9ng/mL e suficiência: 30-100ng/mL. A avaliação antropométrica incluiu peso, altura e circunferências. Massa gorda e massa magra foram avaliadas pelo teste de bioimpedância tetrapolar. Também foram realizadas avaliação clínica e bioquímica. A resistência à insulina foi calculada pelo índice Homeostasis Model Assessment Insulin. Resultados: A análise apontou que as principais alterações dos indivíduos com deficiência de vitamina D foram valores elevados de triglicérides, lipoproteína de muito baixa densidade - colesterol, glicemia de jejum, insulina, hemoglobina glicada, índice de massa corporal, porcentagem de gordura corporal, porcentagem de massa magra, circunferência da cintura e Homeostasis Model Assessment Insulin quando comparados ao grupo Suficiência vitamina D (p<0,05). Conclusão: Observou-se que na deficiência da vitamina D ocorrem importantes alterações tanto no metabolismo como na composição corporal, essas alterações podem contribuir para o surgimento de doenças como diabetes Mellitus e síndrome metabólica.

Interventions to improve patients' compliance with therapies aimed at lowering glycated hemoglobin (HbA1c) in type 1 diabetes: systematic review and meta-analyses of randomized controlled clinical trials of psychological, telecare, and educational interventions.

BACKGROUND: Brazilian records on glycemic control in patients with type 1 diabetes show treatment efficacy. Poor patient adherence to therapeutic proposals influences these results and can be associated with social, psychological, and economic aspects, besides others factors. The aim of this study was to evaluate the efficacy of psychological, telecare, and educational interventions to improve treatment compliance among patients with type 1 diabetes. Compliance was assessed indirectly using reduction of glycated hemoglobin (HbA1c) as the principal outcome measure. METHODS: Systematic review and meta-analyses of randomized controlled clinical trials (RCTs) were performed using Medline, Embase, Cochrane and Scopus databases up to April 2015. The following medical subject headings were used: Diabetes Mellitus, Type 1, Patient Compliance or Adherence, Hemoglobin A, glycated, and Randomized Controlled Trial. The principal outcome was change in HbA1c between baseline and follow-up. Where appropriate, trials were combined in meta-analysis using fixed effects models. RESULTS: From 191 articles initially identified, 57 were full text reviewed, and 19 articles met the inclusion criteria providing data from 1782 patients (49.4 % males, age 18 years). The RCTs (2 to 24 months in duration) were divided into four groups according to type of intervention: psychology (seven studies; 818 patients), telecare (six studies; 494 patients); education (five studies; 349 patients), and psychoeducation (one study; 153 patients). All studies reported some type of adherence measurement of the interventions. Decrease in HbA1c was observed after psychology (MD -0.310; 95 % CI, -0.599 to -0.0210, P = 0.035) but not after telecare (MD -0.124 %; 95 % CI, -0.268, 0.020; P = 0.090) or educational (MD -0.001; 95 % CI, -0.202, 0.200; P = 0.990) interventions. CONCLUSION: Psychological approaches to improve adherence to diabetes care treatment modestly reduced HbA1c in patients with type 1 diabetes; telecare and education interventions did not change glycemic control. However, the limited number of studies included as well as their methodological quality should be taken into account.

Insulin resistance parameters in users of the injectable contraceptive depot medroxyprogesterone acetate during one year of use.

OBJECTIVES: The aim of the study was to assess insulin resistance parameters using successive homeostasis model assessment (HOMA) and clinical evaluations in healthy new users of depot medroxyprogesterone acetate (DMPA). METHODS: A prospective 12-month study was carried out to compare 31 DMPA users with 25 copper intrauterine device (Cu-IUD; TCu380A) users, matched for age (± 1 year) and body mass index (BMI; ± 1 kg/m(2)). Participants met the following criteria: age 18 to 40 years, BMI < 30 kg/m(2), fasting glucose < 5.5 mmol/l, 2-h glucose after a 75 g oral glucose load < 140 mg/dl. BMI, waist circumference, fasting glucose, fasting insulin and HOMA of insulin resistance (HOMA-IR) were evaluated at baseline and after 6 and 12 months of contraceptive use. Insulin resistance was defined as a HOMA-IR value > 2.7. RESULTS: The DMPA group showed significant increases in BMI, waist circumference, fasting insulin and HOMA-IR throughout the observation period in relation to baseline. Significant increases in BMI and waist circumference were observed in the DMPA group at 12 months compared with the Cu-IUD group. Five DMPA users had abnormal HOMA-IR values, three of whom had gained > 5 kg in weight at 12 months. CONCLUSIONS: HOMA-IR represents a useful tool to indicate changes in carbohydrate metabolism in non-obese DMPA users, especially when accompanied by measurement of clinical parameters such as BMI and waist circumference.

Relation of thyroid hormone abnormalities with subclinical inflammatory activity in patients with type 1 and type 2 diabetes mellitus.

Thyroid hormone (TH) abnormalities are common in patients with diabetes mellitus (DM). These thyroid hormone abnormalities have been associated with inflammatory activity in several conditions but this link remains unclear in DM. We assessed the influence of subclinical inflammation in TH metabolism in euthyroid diabetic patients. Cross-sectional study involving 258 subjects divided in 4 groups: 70 patients with T2DM and 55 patients with T1DM and two control groups of 70 and 63 non-diabetic individuals, respectively. Groups were paired by age, sex, and body mass index (BMI). We evaluated the association between clinical and hormonal variables [thyrotropin, reverse T3 (rT3), total and free thyroxine (T4), and triiodothyronine (T3)] with the inflammation markers C-reactive protein (hs-CRP), serum amyloid A (SAA), and interleukin-6 (IL-6). Serum T3 and free T3 were lower in patients with diabetes (all P < 0.001) compared to the control groups. Interleukin-6 showed positive correlations with rT3 in both groups (P < 0.05). IL-6 was independently associated to FT3/rT3 (B = -0.193; 95% CI -0.31; -0.076; P = 0.002) and FT4/rT3 (B = -0.107; 95% CI -0.207; -0.006; P = 0.039) in the T1DM group. In the T2DM group, SAA (B = 0.18; 95% CI 0.089; 0.271; P < 0.001) and hs-CRP (B = -0.069; 95% CI -0.132; -0.007; P = 0.03) predicted FT3 levels. SAA (B = -0.16; 95% CI -0.26; -0.061; P = 0.002) and IL6 (B = 0.123; 95% CI 0.005; 0.241; P = 0.041) were related to FT4/FT3. In DM, differences in TH levels compared to non-diabetic individuals were related to increased subclinical inflammatory activity and BMI. Altered deiodinase activity was probably involved. These findings were independent of sex, age, BMI, and HbA1c levels.

Dyspeptic symptoms in patients with type 1 diabetes: endoscopic findings, Helicobacter pylori infection, and associations with metabolic control, mood disorders and nutritional factors.

OBJECTIVES: To evaluate, in a group of patients with long-standing type 1 diabetes (DM1), an association of dyspepsia symptoms with: changes in the gastroduodenal mucosa, infection by Helicobacter pylori, glycemic control, and psychological and nutritional factors. SUBJECTS AND METHODS: A total of 32 patient with DM1 were studied (age: 38 ± 9 years; females: 25; diabetes duration: 22 ± 5 years). All patients answered a standardized questionnaire for the evaluation of gastrointestinal symptoms and underwent upper gastrointestinal endoscopy, with gastric biopsies for the evaluation of Helicobacter pylori infection. The presence of anxiety and depression was evaluated by the HAD scale. Nutritional parameters were BMI, arm and waist circumference, skinfold measurement, and body fat percentage. RESULTS: Upper endoscopy detected lesions in the gastric mucosa in 34.4% of the patients, with similar frequency in those with (n = 21) and without dyspepsia (n = 11). The patients with dyspepsia complaints showed greater frequency of depression (60% vs. 0%; p = 0.001), higher values for HbA1c (9.6 ± 1.7 vs. 8.2 ± 1.3%; p = 0.01) and lower values for BMI (24.3 ± 4.1 vs. 27.2 ± 2.6 kg/m2; p = 0.02), body fat percentage (26.6 ± 6.2 vs. 30.8 ± 7.7%; p = 0.04), and waist circumference (78.7 ± 8 vs. 85.8 ± 8.1 cm; p = 0.02). No association was found between the symptoms and the presence of Helicobacter pylori. CONCLUSIONS: Dyspepsia symptoms in patients with long-standing DM1 were associated with glycemic control and depression, and they seem to negatively influence the nutritional status of these patients.

Dyspeptic symptoms in patients with type 1 diabetes: endoscopic findings, Helicobacter pylori infection, and associations with metabolic control, mood disorders and nutritional factors

Objectives To evaluate, in a group of patients with long-standing type 1 diabetes (DM1), an association of dyspepsia symptoms with: changes in the gastroduodenal mucosa, infection by Helicobacter pylori, glycemic control, and psychological and nutritional factors. Subjects and methods A total of 32 patient with DM1 were studied (age: 38 ± 9 years; females: 25; diabetes duration: 22 ± 5 years). All patients answered a standardized questionnaire for the evaluation of gastrointestinal symptoms and underwent upper gastrointestinal endoscopy, with gastric biopsies for the evaluation of Helicobacter pylori infection. The presence of anxiety and depression was evaluated by the HAD scale. Nutritional parameters were BMI, arm and waist circumference, skinfold measurement, and body fat percentage. Results Upper endoscopy detected lesions in the gastric mucosa in 34.4% of the patients, with similar frequency in those with (n = 21) and without dyspepsia (n = 11). The patients with dyspepsia complaints showed greater frequency of depression (60% vs. 0%; p = 0.001), higher values for HbA1c (9.6 ± 1.7 vs. 8.2 ± 1.3%; p = 0.01) and lower values for BMI (24.3 ± 4.1 vs. 27.2 ± 2.6 kg/m2; p = 0.02), body fat percentage (26.6 ± 6.2 vs. 30.8 ± 7.7%; p = 0.04), and waist circumference (78.7 ± 8 vs. 85.8 ± 8.1 cm; p = 0.02). No association was found between the symptoms and the presence of Helicobacter pylori. Conclusions Dyspepsia symptoms in patients with long-standing DM1 were associated with glycemic control and depression, and they seem to negatively influence the nutritional status of these patients. .
