Sex-driven factors associated with anxiety and depression in autoimmune diabetes.

AIM: To analyze the prevalence of anxiety and depression in a large cohort of adults with autoimmune diabetes, identifying sex-driven associated factors. MATERIALS AND METHODS: In this cross-sectional study, we enrolled 553 consecutive adults with Type 1 diabetes mellitus or latent autoimmune diabetes in adults who came to the Division of Endocrinology of the S.Orsola-Malpighi Polyclinic, Bologna (Italy), to receive their second dose of SARS-CoV-2 vaccine. We administered the questionnaires: Hospital Anxiety and Depression Scale, Diabetes Distress Scale, Diabetes-related Quality of Life, Diabetes Treatment Satisfaction Questionnaire. We collected clinical and biochemical data and 14 days glucose metrics in patients with sensor use > 70% in a time span of ± 4 months from the questionnaires' administration. We excluded 119 patients from our analyses with missing data (final cohort n = 434: 79% of those enrolled). RESULTS: Anxiety and depression prevalence was respectively 30.4% and 10.8%. According to the multivariate analysis, higher diabete-related emotional burden, lower treatment satisfaction, but not physician-related distress, were risk factors for anxiety and depression; female sex was associated with anxiety (OR 0.51, 95% 0.31-0.81; p = 0.005); in women, depression was associated with increasing age (males vs. females OR 0.96 per 1 year increase, 95% CI 0.92-1.00; p = 0.036), whilst in men with HbA1c (OR 1.08 per 1 mmol/mol increase, 95% CI 1.03-1.13; p = 0.002). CONCLUSION: Nearly 1/3 of patients with autoimmune diabetes suffers from anxiety and 1/10 from depression. These conditions are associated with independent modifiable and non-modifiable characteristics. For depression, these characteristics differ between males and females.

Association between Albumin Alterations and Renal Function in Patients with Type 2 Diabetes Mellitus.

Diabetic kidney disease (DKD) is a major cause of morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM). The aim of this study was to investigate whether albumin structural alterations correlate with DKD severity and evaluate whether native and reduced albumin concentrations could complement the diagnosis of DKD. To this end, one hundred and seventeen T2DM patients without (n = 42) and with (n = 75) DKD (DKD I-III upon KDIGO classification) were evaluated; the total albumin concentration (tHA) was quantified by a bromocresol green assay, while structural alterations were profiled via liquid chromatography-high-resolution mass spectrometry (LC-HRMS). The concentrations of native albumin (eHA, effective albumin) and reduced albumin (rHA) were subsequently assessed. The HRMS analyses revealed a reduced relative amount of native albumin in DKD patients along with an increased abundance of altered forms, especially those bearing oxidative modifications. Accordingly, both eHA and rHA values varied during the stages of progressive renal failure, and these alterations were dose-dependently correlated with renal dysfunction. A ROC curve analysis revealed a significantly greater sensitivity and specificity of eHA and rHA than of tHA for diagnosing DKD. Importantly, according to the multivariate logistic regression analysis, the eHA was identified as an independent predictor of DKD.

Impact of Baseline Clinical Variables on SGLT2i's Antiproteinuric Effect in Diabetic Kidney Disease.

INTRODUCTION: Proteinuria is a major risk factor for the progression of chronic kidney disease (CKD). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) demonstrated a nephroprotective and antiproteinuric effect in people with type 2 diabetes (T2DM) and proteinuric CKD. We conducted a retrospective study to evaluate clinical and laboratory variables that can help predict proteinuria reduction with SGLT2i therapy. MATERIALS AND METHODS: Patients affected by T2DM and CKD who started any SGLT2i were included in the study. Patients were stratified into two subgroups, Responder (R) and non-Responder (nR), based upon the response to the therapy with SGLT2i, namely the reduction in a 24 h urine proteins test (uProt) of ≥30% from baseline levels. The aim of the study is to analyse differences in baseline characteristics between the two groups and to investigate the relationship between them and the proteinuria reduction. A Kruskal-Wallis test, unpaired t-test and Chi2 test were used to test the difference in means and the percentage (%) between the two groups. Linear and logistic regressions were utilized to analyse the relationship between proteinuria reduction and basal characteristics. RESULTS: A total of 58 patients were enrolled in the study: 32 patients (55.1%) were in the R group and 26 patients (44.9%) in the nR group. R's patients had a significant higher uProt at baseline (1393 vs. 449 mg/24 h, p = 0.010). There was a significant correlation between baseline uProt and proteinuria reduction with SGLT2i in both univariate (ß = -0.43, CI -0.55 to -031; p < 0.001) and multivariate analyses (ß = -0.46, CI -0.57 to -0.35, p < 0.001). In the multivariate analysis, there was a significant positive correlation between the estimated glomerular filtration rate (eGFR) and proteinuria reduction (ß = -17, CI -31 to -3.3, p = 0.016) and a significant negative correlation with body mass index (BMI) (ß = 81, CI 13 to 50, p = 0.021). The multivariate logistic regressions show a positive correlation of being in the R group with diabetic retinopathy at baseline (Odds Ratio (OR) 3.65, CI 0.97 to 13.58, p = 0.054), while the presence of cardiovascular disease (CVD) at baseline is associated with being in the nR group (OR 0.34, CI 0.09 to 1.22, p = 0.1), even if these statements did not reach statistical significance. CONCLUSIONS: In this real-life experience, following the administration of SGLT2i, a reduction of more than 30% in proteinuria was observed in more than half of the patients, and these patients had a significantly higher baseline proteinuria value. Variables such as eGFR and BMI are variables that, considered in conjunction with proteinuria, can help predict treatment response before therapy initiation. Different phenotypes of diabetic kidney disease may have an impact on the antiproteinuric response.

Sleep quality and sex-related factors in adult patients with immune-mediated diabetes: a large cross-sectional study.

AIM: To analyze sleep quality and its relationships with clinical and biochemical features in a large cohort of adults with autoimmune diabetes. METHODS: We administered to 553 patients with autoimmune diabetes the questionnaires: Pittsburgh Sleep Quality Index (PSQI), diabetes distress scale, diabetes-related quality of life and diabetes treatment satisfaction questionnaire. We excluded patients with missing HbA1c ± 4 months from PSQI administration or incorrect PSQI compilation (n = 110). RESULTS: Altered sleep quality was recorded in 142/443 subjects (32%), insufficient total sleep time in 177/443 (40%). The altered sleep quality group had higher HbA1c (median 56 mmol/mol [interquartile range-IQR 49-62] vs 59 [IQR 52-68]; P < 0.001), higher average HbA1c in the previous 36 months (59 mmol/mol [IQR 54-68] vs 56 [IQR 51-62]; P < 0.001), and more individuals with HbA1c > 53 mmol/mol (74.6% vs 62.8%; P = 0.014). Diabetes duration (P = 0.63), type of insulin delivery (P = 0.48) and glucose monitoring (P = 0.35) were uninfluential. Patients with altered sleep quality showed higher prevalence of autoimmune (42 vs 28%; P = 0.005) and mental diseases (12 vs 4%; P = 0.002); there were greater emotional distress, and lower quality of life and treatment satisfaction (P < 0.001 for all), irrespective of sex. Men with altered sleep quality had higher HbA1c and prevalence of autoimmune diseases. Women showed greater prevalence of psychiatric disorders. Average HbA1c of the previous 36 months, autoimmune or psychiatric disorders were independent predictive factors for altered sleep quality. CONCLUSION: One-third of the patients with autoimmune diabetes showed altered sleep quality, which associates with worse glycemic control, and autoimmune and mental disorders, with sex-specific differences.

Tablet and oral liquid L-thyroxine formulation in the treatment of naïve hypothyroid patients with Helicobacter pylori infection.

To compare the clinical efficacy of tablet and oral liquid L-thyroxine (LT4) formulation in naïve hypothyroid subjects with Helicobacter pylori infection. Forty-seven adult naïve hypothyroid subjects with dyspeptic symptoms were investigated with upper endoscopy and divided into: 28 patients with Helicobacter pylori infection (Group A); 15 patients without gastric alterations (group B); 4 patients with autoimmune gastritis were excluded from the study. Subjects were randomly treated with a same dose of LT4 tablet (TAB) or oral liquid formulation (SOL), for 9 months on group A and 6 months on group B. Helicobacter pylori infection was eradicated after 3 months of LT4 treatment. On group A, after 3 months (before Helicobacter pylori eradication), subjects treated with SOL showed a greater thyroid-stimulating hormone reduction (ΔTSH3-0: TAB = -4.1 ± 4.6 mU/L; SOL = -7.7 ± 2.5 mU/L; p = 0.029) and a greater homogeneity in the thyroid-stimulating hormone values (TSH3mo: TAB = 5.7 ± 4.9 mU/L; SOL = 4.1 ± 2.0 mU/L; p = 0.025), compared to LT4 tablet. At 9 months (after 6 months of Helicobacter pylori eradication) mean thyroid-stimulating hormone values were lower in subjects treated with LT4 tablet (TSH9mo: TAB = 1.8 ± 1.2 mU/L; SOL = 3.2 ± 1.7 mU/L; p = 0.006). On group B no difference were observed, at each time point, in the mean thyroid-stimulating hormone values and thyroid-stimulating hormone variations between two LT4 formulations. LT4 liquid formulation may produce a better clinical response compared to the tablet formulation in hypothyroid subjects with Helicobacter pylori infection.

Defining Hyperandrogenism in Women With Polycystic Ovary Syndrome: A Challenging Perspective.

OBJECTIVE: This study was designed to assess the steroid profiling by liquid chromatography coupled with tandem mass spectrometry in PCOS women with different phenotypes. DESIGN: Cross-sectional study. SETTING: University hospital of Bologna, Italy. PATIENTS AND METHODS: A total of 156 PCOS women and 141 controls comparable for age were investigated. All underwent a steroid profiling by liquid chromatography coupled with tandem mass spectrometry. Metabolic parameters were also investigated and hirsutism was measured by the modified Ferriman-Gallwey (mF-G) score. RESULTS: Three distinct phenotypes were initially defined according to the combination of hirsutism (mF-G ≥ 8) and/or high testosterone (T) (HA), oligo-amenorrhea (OA), and polycystic ovarian morphology (PCOm); OA + PCOm (n = 43), HA + OA (n = 65), and HA + OA + PCOm (n = 45). T, androstenedione (A), and free androgen index (FAI) levels progressively increased in the 3 PCOS phenotypes with respect to the controls, with the highest values in the HA + OA + PCOm phenotype. The various combinations of hirsutism, high T, high A, and high FAI made it possible to categorize the 3 original phenotypes into 8 hyperandrogenic subgroups, characterized by divergent additional steroid profile and metabolic pattern. A total of 90% of patients with PCOS thus proved hyperandrogenic. Interestingly, half the PCOS women originally classified as having the OA-PCOm phenotype were categorized in a hyperandrogenic subgroup. No significant correlation was found between T, A, and the mF-G score. In contrast, significant correlation was found between A and both T and FAI. CONCLUSIONS: This study provides evidence that, by including a steroid profile in the definition of hyperandrogenemia, the majority of women with PCOS are hyperandrogenic, although a clinical and biochemical heterogeneity exists. In addition, these data demonstrate that hirsutism and high androgen levels cannot be used indifferently to define hyperandrogenism.

Body mass index-independent metabolic alterations in narcolepsy with cataplexy.

STUDY OBJECTIVES: To contribute to the anthropometric and metabolic phenotyping of orexin-A-deficient narcoleptic patients, and to explore a possible risk of their developing a metabolic syndrome. DESIGN: We performed a cross-sectional study comparing metabolic alterations in patients with narcolepsy with cataplexy (NC) and patients with idiopathic hypersomnia without long sleep time. SETTING: University hospital. PATIENTS: Fourteen patients with narcolepsy with cataplexy and 14 sex and age-matched patients with idiopathic hypersomnia without long sleep time. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Metabolic parameters were evaluated by measuring body mass index (BMI), waist circumference (also with abdominal computed tomography), blood pressure, and daily calorie intake (3-day diary). Chronotypes were assessed through the morningness-eveningness questionnaire. Lumbar puncture for cerebrospinal fluid orexin-A determination and HLA typing were performed. Patients with narcolepsy with cataplexy (all HLA DQB1*0602 positive and with cerebrospinal fluid orexin-A levels < 110 pg/mL) had a higher BMI and BMI-independent metabolic alterations, namely waist circumference, high-density lipoprotein cholesterol, and glucose/insulin ratio (an insulin resistance index), with respect to patients with idiopathic hypersomnia without long sleep time (cerebrospinal fluid orexin-A levels > 300 pg/mL). Despite lower daily food intake, patients with narcolepsy with cataplexy displayed significant alterations in metabolic parameters resulting in a diagnosis of metabolic syndrome in more than half the cases. CONCLUSIONS: BMI-independent metabolic alterations and the relative hypophagia of patients with narcolepsy with cataplexy, as compared with patients with idiopathic hypersomnia without long sleep time, suggest that orexin-A influences the etiology of this phenotype. Moreover, considering that these dysmetabolic alterations are present from a young age, a careful metabolic follow-up of patients diagnosed with narcolepsy with cataplexy is mandatory.
