Assessment of the spectrum of depression and bipolarity in patients with type 1 diabetes.

AIMS: The aim of the study was to check the prevalence of unipolarity (depression), bipolarity, as well as the quality of sleep and temperament traits in patients with type 1 diabetes (T1DM) who are provided with optimal conditions of diabetes care and to identify possible risk factors connected with affective traits. MATERIALS AND METHODS: Out of the 107 T1DM patients, 78 (54 females, 24 males) were included for the analysis (HbA1c [%] 7.11 ± 1.0, BMI [kg/m2 ] 25.3 ± 5.6; Years of disease duration [N] 13.7 ± 8.3). The patients filled in a set of questionnaires during their regular visit to the outpatient clinic. Three patients from the whole group were on intensive insulin therapy with Multiple Daily Injections (MDI) and Self-Monitoring of Blood Glucose (SMBG), all the rest were on various types of personal insulin pumps (years on insulin pump [N] 9.1 ± 4.5). All the patients were on regular diabetologist care, with regular visits in a Centre for Advanced Technologies in Diabetes (at least every 6 months). RESULTS: In QIDS-S (full explanation and abbreviation 26 patients (33.8%) were screened positive for depression, in PHQ (full explanation and ab 57.7% of the patients (45 patients) had symptoms of depression (age was negatively correlated with PHQ score [r = -0.26; p = 0.023]). In CES-D 16 (20%) of the patients assessed their present affect as depressed. None of the analysed clinical variables correlated with depression scores. In the Mood Disorder Questionnaire (MDQ), 16 patients reported having symptoms of bipolarity (20.5% vs. 79.5%). Hypomania Checklist (HCL) analysis indicated 10 patients with bipolar traits (>14) (14.9% vs. 85.1%). None of the analysed clinical variables correlated with HCL results. 11.5% of patients were indicated to be of morning type. Morningness was more often seen in younger patients (r = 0.39; p = 0.001). As many as 46.6% declared that they had poor sleep quality. The temperament traits analysis correlated with clinical parameters: Cyclothymic temperament trait was negatively correlated with age (r = -0.30; p = 0.007) and positively with HbA1c level (r = 0.30; p = 0.025). Hyperthymic temperament was positively correlated with (BMI r = 0.28; p = 0.016). Quality of sleep was highly correlated with depressive symptoms CESD (r = 0.61, p = 0.001), PHQ Score (r = 0.62; p = 0.001), QISD (r = 0.68; p = 0.001) and bipolarity MDQ (p = 0.50, p = 0.001) and HCL (r = 0.42, p = 0.001). In addition, QIDS was shown to be correlated with the following features of temperament: depressive factor (r = 0.41; p = 0.001), irritable factor (r = 0.53; p = 0.001), cyclothymic factor (r = 0.59; p = 0.001), anxious factor (r = 0.58, p = 0.001). CONCLUSIONS: The prevalence of affective disorders and poor sleep quality in the examined T1DM patients was much higher than in the general population. Even if the patients have in general good glycaemic control, their mental health condition should not be neglected. Well organised cooperation between patients, diabetologists, psychiatrists and psychotherapists is needed (Clinical Trials Identifier: NCT04616391).

Efficacy and safety of long-term insulin pump treatment in patients with type 1 diabetes aged over 50 years.

Continuous subcutaneous insulin infusion (CSII) therapy using insulin pumps has become widely used in the treatment of type 1 diabetes mellitus (T1DM). This retrospective study aimed to assess the efficacy and safety of long-term insulin pump treatment in patients with T1DM aged ≥50 years. The study included patients aged ≥50 years, who had a diagnosis of T1DM based on clinical criteria and/or presence of autoantibodies characteristic of autoimmune diabetes, and had received ≥5 years of recent and uninterrupted treatment with a personal insulin pump. We analyzed records on HbA1c levels across the entire observation period. The cohort comprised 17 patients, of whom 6 (35%) were men and 11 (65%) were women. The mean duration of observation was 6.6 years, during which patients had a mean of 8.4 HbA1c measurements. Mean HbA1c level over the entire observation period was 6.7% (range, 5.3-7.4%). Overall, 11 patients (65%) had mean HbA1c levels at the ADA-recommended target of <7% and 5 patients (29%) had mean HbA1c <6.5%. Mean HbA1c level was significantly lower at the end of the observation period than at the start (6.52% versus 6.91%; difference, -0.39%; p < 0.01), indicating an improvement in glycaemic control over time. On average, patients experienced one level 1 hypoglycaemia episode every 2.4 days. This retrospective analysis of at least 5 years of follow-up of selected patients with T1DM aged ≥50 years at the start of observation, showed that CSII is a safe and effective treatment option in this age group.

Association of short- and long-term metabolic control parameters with personality traits in adult type 1 diabetes treated with personal insulin pumps. / Korelacja krótko- i dlugoterminowych parametrów kontroli metabolicznej z cechami osobowosci u doroslych chorych na cukrzyce typu 1 leczonych za pomoca osobistych pomp insulinowych.

AIM: Several studies have assessed the association between personality traits and metabolic outcomes in children and adolescents with type 1 diabetes (T1DM). The aim of this observational single-visit study was to investigate whether specific personality traits were related to the degree of metabolic control/diabetes duration in adult T1DM patients. METHOD: Data were collected from 56 adults (40 men) with T1DM treated in a tertiary care center. "Big Five" personality traits were assessed using the NEO-Five Factor Inventory questionnaire. Several variables were obtained from the insulin pumps, glucometers and blinded continuous glucose monitoring system. RESULTS: All personality traits but neuroticism (low level of the trait) showed average intensity. Agreeableness was associated with most variables from CGMS data. Higher conscientiousness was associated with longer diabetes duration. Higher neuroticism was correlated with greater glycemic variability (GV), while high Extraversion was associated with lower GV. Lower Openness was associated with prolonged time in clinically significant hypoglycaemia. CONCLUSIONS: Our study suggest that personality traits manifest in individual approach to diabetes management and emotion regulation, translating also into the attitude to treatment. On the other hand, T1DM patients' overall trait scores were consistent with healthy nonpsychiatric norms, which debunks myths and stereotypes suggesting that chronic disease is usually associated with psychopathology.

Psychological Crisis Intervention for COVID-19 Lockdown Stress in Patients With Type 1 Diabetes Mellitus: Survey Study and Qualitative Analysis.

BACKGROUND: The COVID-19 pandemic has challenged the worldviews of most people. Social isolation after the COVID-19 lockdown has not only led to economic difficulties but also resulted in adverse psychological reactions. As in most countries, including Poland, this situation has been very challenging for patients with type 1 diabetes mellitus (T1DM). In Poland, a crisis intervention team for patients with T1DM was established. The goal of the team was to provide psychological support for these patients, if needed, and to present information concerning how these patients may obtain medical consultations and prescriptions. OBJECTIVE: We aimed to analyze the psychological parameters and main emotional reactions of patients with T1DM during the COVID-19 lockdown. METHODS: An email with information concerning the possibility of having a web-based consultation with psychologists and psychiatrists and an attached set of psychological tests was sent to all patients with T1DM who were under the care of an outpatient diabetes clinic. The consultations were performed by licensed clinical psychologists and psychologists. This study was approved by the Bioethics Committee of the Jagiellonian University in Krakow, Poland. RESULTS: The patients who decided to use psychological support had statistically higher levels of anxiety (state P=.043; trait P=.022), stress (P=.001) than those of patients from the group who did not seek support. CONCLUSIONS: The presented intervention team may be perceived as an example of important and successful cooperation and communication between specialists of different fields of medicine (diabetology, psychiatry, and psychology) in a crisis situation.

Intermittently Scanned Continuous Glucose Monitoring Data of Polish Patients from Real-Life Conditions: More Scanning and Better Glycemic Control Compared to Worldwide Data.

Background: Randomized trials and observational studies have shown that the use of FreeStyle Libre® intermittently scanned continuous glucose monitoring system (isCGMS) is associated with improved glycemic indices and quality of life. Materials and Methods: In this retrospective, real-world data analysis, we described country-specific glucometrics among isCGMS users from Poland and compared them with international data. The analyzed time period for the Polish data ranged between August 2016 and August 2020, and the analyzed time period for the international data ranged from September 2014 to August 2020. Results: Data from the Polish population were collected from 10,679 readers and 92,627 sensors with 113 million automatically recorded glucose readings. The worldwide database included information from 981,876 readers and 11,179,229 sensors with 13.1 billion glucose readings. On average, the users of isCGMS from Poland performed substantially more scans/day (21.2 ± 14.2 vs. 13.2 ± 10.7), achieved lower eHbA1c (7.0% ± 1.2% vs. 7.5% ± 1.5%), and spent more time-in-range (TIR) (64.2% ± 17.3% vs. 58.1% ± 20.3%) and less time-above-range (TAR) (29.7% ± 18.0% vs. 36.6% ± 21.3%) (P < 0.0001 for all comparisons). Moreover, they were more likely to achieve TIR >70% (36.3% vs. 28.8%), but spent more time-below-range (TBR) (4.7% vs. 3.6%). Our results confirmed that analyzed glucometrics improve as the scan rate frequency increases. However, at a similar scanning frequency to the comparative group, users from Poland achieved lower eHbA1c, higher TIR, and lower TAR, but higher TBR. Conclusions: We report more scanning and better glycemic control in isCGMS users in Poland than worldwide. The cause of this observation remains unknown. Our data also show that in real-life practice, a large number of patients may be willing to perform scanning more frequently than it is usually assumed.

Number of circulating pro-angiogenic cells, growth factor and anti-oxidative gene profiles might be altered in type 2 diabetes with and without diabetic foot syndrome.

AIMS/INTRODUCTION: Type 2 diabetes is often complicated by diabetic foot syndrome (DFS). We analyzed the circulating stem cells, growth factor and anti-oxidant gene expression profiles in type 2 diabetes patients without or with different forms of DFS. MATERIALS AND METHODS: Healthy volunteers (n = 13) and type 2 diabetes patients: (i) without DFS (n = 10); or with (ii) Charcot osteoneuropathy (n = 10); (iii) non-infected (n = 17); (iv) infected (n = 11); and (v) healed ulceration were examined (n = 12). Peripheral blood endothelial progenitor cells (EPC), mesenchymal stem cells (MSC), hematopoietic stem cells (HSC) and very small embryonic-like (VSEL) cells were phenotyped using flow cytometry. Plasma cytokine concentrations and gene expressions in blood cells were measured by Luminex and quantitative real-time polymerase chain reaction assays, respectively. RESULTS: Patients with non-complicated type 2 diabetes showed reduced HMOX1 expression, accompanied by HMOX2 upregulation, and had less circulating EPC, MSC or HSC than healthy subjects. In contrast, VSEL cells were elevated in the type 2 diabetes group. However, subjects with DFS, even with healed ulceration, had fewer VSEL cells, more CD45-CD29(+)CD90(+)MSC, and upregulated HMOX1 when compared with the type 2 diabetes group. Patients with Charcot osteopathy had lowered plasma fibroblast growth factor-2. Elevated plasma tumor necrosis factor-α and decreased catalase expression was found in all diabetic patients. CONCLUSIONS: Patients with type 2 diabetes and different forms of DFS have an altered number of circulating stem cells. Type 2 diabetes might also be associated with a changed plasma growth factor and anti-oxidant gene expression profile. Altogether, these factors could contribute to the pathogenesis of different forms of DFS.
