Diabetes Management Delivery and Pregnancy Outcomes in Women with Gestational Diabetes Mellitus during the First Wave of the 2020 COVID-19 Pandemic: A Single-Reference Center Report.

OBJECTIVES: The COVID-19 pandemic has forced a rapid adaptation of healthcare services to secure care for many patient groups. This includes women with gestational diabetes mellitus (GDM). We evaluated the impacts of the first COVID-19 wave on parameters such as the GDM treatment, glycemic control, and pregnancy outcomes. METHODS: In this retrospective study from a reference diabetes center (Krakow, Poland), we compared patient data from two different time periods: the first wave of the COVID-19 pandemic (March 2020-June 2020) and the preceding five months (October 2019-February 2020). Data was collected from the medical records and telephone surveys. RESULTS: We included 155 consecutive women (group N1 = 73 and group N2 = 82 from the COVID-19 pandemic period and non-COVID-19 period, respectively). During the COVID-19 pandemic, almost half of all GDM women (N1 = 36, 49.3%) used telemedicine as a method of contacting their diabetic specialists while this tool was not utilized in the earlier period. Moreover, these patients reported difficulties in performing blood glucose self-control more often (N1 = 20, 27.4%, vs N2 = 7, 8.5%; p ≤ 0.01) and spent less time on diabetes education than the control group on average (N1 = 39, 53.4%, vs N2 = 9, 9.8% below 2 hours of training; p ≤ 0.01). Most analyzed glycemic parameters and pregnancy outcomes were similar. Differences were found with respect to the incidence of prolonged labor (N1 = 12, 16.4%, vs N2 = 3, 3.7%; p ≤ 0.01) and preeclampsia (N1 = 0 vs N2 = 7, 8.5%; p = 0.01). CONCLUSION: In this single-center observational study, the first wave of the COVID-19 pandemic did not seem to have a negative impact on pregnancy outcomes in GDM women, despite the difficulties in diabetes management delivery.

Neurological symptoms in hospitalised patients with COVID-19 and their association with in-hospital mortality.

OBJECTIVES: To evaluate the spectrum of neurological symptoms in patients with COVID-19 during the first 14 days of hospitalisation and its association with in-hospital mortality. MATERIAL AND METHODS: We included 200 patients with RT-PCR-confirmed COVID-19 admitted to University Hospital in Krakow, Poland. In 164 patients, a detailed questionnaire concerning neurological symptoms and signs was performed prospectively within 14 days of hospitalisation. In the remaining 36 patients, such questionnaires were completed retrospectively based on daily observations in the Department of Neurology. RESULTS: During hospitalisation, 169 patients (84.5%) experienced neurological symptoms; the most common were: fatigue (62.5%), decreased mood (45.5%), myalgia (43.5%), and muscle weakness (42.5%). Patients who died during hospitalisation compared to the remainder were older (79 [70.5-88.5] vs. 63.5 [51-77] years, p = 0.001), and more often had decreased level of consciousness (50.0% vs. 9.3%, p < 0.001), delirium (33.3% vs. 4.4%, p < 0.001), arterial hypotension (50.0% vs. 19.6%, p = 0.005) or stroke during (18.8% vs. 3.3%, p = 0.026) or before hospitalisation (50.0% vs. 7.1, p < 0.001), whereas those who survived more often suffered from headache (42.1% vs. 0%, p = 0.012) or decreased mood (51.7% vs. 0%, p = 0.003). CONCLUSIONS: Most hospitalised patients with COVID-19 experience neurological symptoms. Decreased level of consciousness, delirium, arterial hypotension, and stroke during or before hospitalisation increase the risk of in-hospital mortality.

Changes in the clinical characteristics of women with gestational diabetes mellitus - a retrospective decade-long single center analysis.

AIMS: Gestational diabetes mellitus (GDM) is an emerging worldwide problem. Changes in clinical characteristics of women affected by GDM in a long-term perspective are still not properly investigated. We aimed to examine such changes over a decade in a retrospective single-center analysis. METHODS: The medical documentation from Department of Metabolic Diseases, Krakow, Poland was analyzed. We included 633 women consecutively diagnosed with GDM in one of three time intervals: 2007-2008 (N = 157), 2012-2013 (N = 272), 2016-2017 (N = 234). Statistical analyses were performed. RESULTS: Comparison of the three groups identified differences in the mean age of women at the GDM diagnosis (30.7 ± 5.0 years vs. 31.2 ± 4.7 vs. 32.5 ± 4.7, respectively, starting from the earliest 2007-2008 group), pregnancy week at GDM diagnosis (28.0 ± 5.3 wks. vs. 25.9 ± 4.9 vs. 23.4 ± 6.8), the proportion of women diagnosed before the 24th week of pregnancy (12.8% vs. 16.5% vs. 31.3%), and gestational weight gain (12.4 ± 5.0 kg vs. 10.4 ± 5.2 vs. 10.0 ± 5.7); (p = 0.001 or less for all comparisons). We also found differences for glucose values on fasting and at 2 hours with the highest (0 min) and lowest level (120 min) in the 2016-2017, respectively. Finally, a borderline difference for the weight, but not for BMI, was found (64.1 ± 14.1 kg vs. 66.2 ± 13.1 vs. 67.8 ± 15.6; p = 0.04). Differences were also identified in the post hoc analysis between cohorts. CONCLUSION: This retrospective analysis illustrates changes in characteristics of women with GDM occurring over the period of decade in Poland. They likely result from both epidemiological trends and modifications of the WHO criteria for the GDM diagnosis.

[Hypoglycemia due to antibodies to exogenous insulin in a patient with type 2 diabetes ­ a case report of treatment with new generation oral hypoglycemic agents].

Hypoglycemic syndromes associated with immune reactions against insulin are rare phenomena described predominantly in Asians. Steroid therapy, immunosuppression or plasmapheresis is often required. Case report: A 73-year-old White woman with a 20-year history of type 2 diabetes was admitted to hospital due to recurrent incidents of hypoglycemia that started several months after insulin initiation (lispro 75/25) and increased in severity over the next 5 years. They were accompanied by postprandial hyperglycemia up to 25 mmol/l. The patient's glycated hemoglobin (HbA1c) was 70 mmol/ mol (8.6%). During hypoglycemic episodes recorded serum C-peptide was 0.57-0.73 nmol/l (1.7-2.2 ng/ml), while insulin concentration exceeded 7000 pmol/l (1000 mIU/l). Surreptitious insulin administration was ruled out as was, based on diagnostic imaging, the presence of an insulin secreting tumor. Anti-insulin antibody (AIA) level measured by 125I-insulin binding method was 92.5% (normal < 8.2%). Hypoglycemic episodes occurred for four days after discontinuation of insulin therapy and then resolved completely. Good glycemic control was maintained with metformin, acarbose and dapagliflozin. Three months later dapagliflozin was replaced with vildagliptine due to poor tolerance of a SGLT-2 inhibitor. Patient's HbA1c was 54 mmol/mol (7.1%), total fasting insulin level 2577 pmol/l and AIA binding 85.9%. Over the next year the patient has not experienced hypoglycemia and maintained good glycemic control, as HbA1c level was 53 mmol/l (7.0%) and AIA binding 39.5%. Conclusions: In this rare case of a patient with diabetes and hypoglycemic syndrome related to AIA, we achieved a rapid and stable remission of hypoglycemia without immunosuppression. Good glycemic control, despite 20-year history of diabetes was achieved with oral hypoglycemic agents.
