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.

Education of adult type 1 diabetes patients in a diabetes ward setting: a best practice implementation project.

INTRODUCTION AND OBJECTIVES: Type 1 diabetes is an autoimmune disease that destroys insulin-producing cells in the pancreas. Education is the cornerstone of effective diabetes care. In this implementation project, we aimed to improve compliance with best practices regarding type 1 diabetes educational interventions for adult hospitalized patients. METHODS: This project was guided by the JBI Evidence Implementation Framework. A baseline audit was conducted involving 20 nurses and 20 type 1 diabetes patients who received regular educational measures. Areas of non-compliance were identified and an improvement strategy was implemented. A follow-up audit was then conducted to evaluate the effectiveness of the improvement strategy. The project was conducted in Poland in 2021 in a tertiary referral unit that specializes in the diagnosis and treatment of diabetes. RESULTS: Substantial improvements were noted for all audit criteria after the implementation of strategies to address areas of non-compliance. Use of the education program improved from 0% to 100%. Compliance regarding patients receiving handouts and personalization of the program increased to 100%. We observed a significant improvement from 0% to 80% in the structuring of the program content. CONCLUSIONS: This project successfully improved the quality of education provided for type 1 diabetes patients in all relevant areas. We devised an education program, covering important aspects of diabetes education, with the patients reporting increased satisfaction with the personalized educational measures during their hospital stay.

Characteristics, Mortality, and Clinical Outcomes of Hospitalized Patients with COVID-19 and Diabetes: A Reference Single-Center Cohort Study from Poland.

Background: Diabetes is a risk factor for a severe course of COVID-19. We evaluated the characteristics and risk factors associated with undesirable outcomes in diabetic patients (DPs) hospitalized due to COVID-19. Materials and Methods: The data analysis of patients admitted between March 6, 2020, and May 31, 2021, to the University Hospital in Krakow (Poland), a reference center for COVID-19, was performed. The data were gathered from their medical records. Results: A total number of 5191 patients were included, of which 2348 (45.2%) were women. The patients were at the median age of 64 (IQR: 51-74) years, and 1364 (26.3%) were DPs. DPs, compared to nondiabetics, were older (median age: 70 years, IQR: 62-77 vs. 62, IQR: 47-72, and p < 0.001) and had a similar gender distribution. The DP group had a higher mortality rate (26.2% vs. 15.7%, p < 0.001) and longer hospital stays (median: 15 days, IQR: 10-24 vs. 13, IQR: 9-20, and p < 0.001). DPs were admitted to the ICU more frequently (15.7% vs. 11.0%, p < 0.001) and required mechanical ventilation more often (15.5% vs. 11.3%, p < 0.001). In a multivariate logistic regression, factors associated with a higher risk of death were age >65 years, glycaemia >10 mmol/L, CRP and D-dimer level, prehospital insulin and loop diuretic use, presence of heart failure, and chronic kidney disease. Factors contributing to lower mortality were in-hospital use of statin, thiazide diuretic, and calcium channel blocker. Conclusion: In this large COVID-19 cohort, DPs constituted more than a quarter of hospitalized patients. The risk of death and other outcomes compared to nondiabetics was higher in this group. We identified a number of clinical, laboratory, and therapeutic variables associated with the risk of hospital death in DPs.

Type 1 diabetes outpatient care and treatment effectiveness during COVID-19: A single-center cohort study.

PURPOSE: COVID-19 has brought many challenges for providing quality healthcare for type 1 diabetes (T1DM). We evaluated the impact of the COVID-19 pandemic on the medical care, glycemic control, and selected outcomes in T1DM patients. METHODS: We retrospectively analyzed medical records from 357 T1DM adults enrolled in the Program of Comprehensive Outpatient Specialist Care at the University Hospital in Krakow, and assessed differences in patient data from before the COVID-19 period (March 2019-February 2020) and after it started COVID-19 (March 2020-February 2021). RESULTS: The median HbA1c levels and the percentage of patients within the HbA1c target of <7 % (53 mmol/mol) were similar in both periods: before and after the beginning of the pandemic (6.86 % [51.5 mmol/mol], IQR 6.23-7.58 % [44.6-59.3 mmol/mol] vs. 6.9 % [51.9 mmol/mol], IQR 6.2-7.61 % [44.3-59.7 mmol/mol]; p = 0.50 and 56.3 % vs. 57.1 %, p = 0.42, respectively). However, we observed a rise in BMI and body weight (median 24.25, IQR 21.97-27.05 vs. 24.82, IQR 22.17-27.87 and median weight 71.0 IQR 61-82 vs. 72.55, IQR 55-85; p < 0.001 for both comparisons). There was no reduction in the numbers of total diabetes-related visits (median 4, IQR 4-5 vs. 5, IQR 4-5; p = 0.065), but the frequency of other specialist consultations decreased (2, IQR 0-2 vs. 1, IQR 0-2). During the pandemic, telehealth visits constituted of 1191 out of 1609 (71.6 %) total visits. CONCLUSIONS: In this single-center observation, the COVID-19 pandemic did not have a negative impact on glycemic control in T1DM patients, but the patients' weight did increase. Telemedicine proved to be a valuable tool for T1DM care.

The enteroendocrine-osseous axis in patients with long-term type 1 diabetes mellitus.

INTRODUCTION: The relationship between the gut and skeleton is increasingly recognized as a component of the regulation of carbohydrate metabolism. The aim of our study was to assess the relationship between bone mineral density (BMD), incretin hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), intestinotrophic peptide glucagon-like peptide-2 (GLP-2) and osteocalcin isoforms in patients with long-term type 1 diabetes (T1D) when compared to healthy controls. METHODS: Eighty two patients with long term T1D, treated in the Department of Metabolic Diseases and 53 healthy controls were recruited to the study. Long term disease duration was defined as lasting for more than 10 years. The control group was selected among age- and sex-matched healthy people. Fasting blood samples were collected to measure levels of incretin hormones (GLP-1, GLP-2, GIP), two forms of osteocalcin (uncarboxylated (ucOC), and carboxylated (cOC)), and additional biochemical parameters associated with glucose and bone metabolism (HbA1c, calcium, phosphorus, 25(OH)D3, PTH). RESULTS: Patients with T1D had higher BMI than in controls (p = 0.02). There was no difference in BMD at the lumbar spine and the femoral neck between patients with long-term T1D and healthy ones. Z-score values in both groups were within normal ranges. The level of GIP was significantly higher in T1D patients (p = 0.0002) in comparison to the healthy ones. The levels of GLP-1 and GLP-2 did not differ between T1D patients and controls. In the T1D group, strong, positive associations were found between serum levels of GLP-1 and cOC (r = 0.546, p < 0.001) and between GLP-1 and total OC (r = 0.51, p < 0.001), also after adjusting for BMI (p < 0.001 and p < 0.001, respectively). Significant positive associations were also found between serum levels of GLP-2 and cOC (r = 0.27, p = 0.013) and between GLP-2 and total OC (r = 0.25, p = 0.018), also in a multivariate regression (p = 0.009, p = 0,175, respectively). Moreover, in T1D patients, GLP-1 correlated positively with the femoral neck BMD (g/cm2) (r = 0.265, p = 0.016) and this association was statistically significant after adjusting for BMI (p = 0.011). These correlations were not present in the control group. The only significant correlation observed in the control group was between OC and BMD of the neck (p = 0.049 for neck BMD g/cm2, and p = 0.041 for neck Z-score). CONCLUSIONS: Our data suggests an effect of gut hormones on bone in long-term T1D, which could be associated with OC activity, however we did not find a direct connection with glucose metabolism. GLP-1 could have a possible, protective role on bone mineral density in patients with T1D. The data from our study suggests that gut hormones could be considered as a new link in the skeleton - pancreatic endocrine loop in patients with T1D.

Association between cardiovascular disease, cardiovascular drug therapy, and in-hospital outcomes in patients with COVID-19: data from a large single-center registry in Poland.

BACKGROUND: The coronavirus disease 19 (COVID-19) recently became one of the leading causes of death worldwide, similar to cardiovascular disease (CVD). Coexisting CVD may influence the prognosis of patients with COVID-19. AIMS: We analyzed the impact of CVD and the use of cardiovascular drugs on the in-hospital course and mortality of patients with COVID-19. METHODS: We retrospectively studied data for consecutive patients admitted to our hospital, with COVID-19 between March 6th and October 15th, 2020. RESULTS: 1729 patients (median interquartile range age 63 [50-75] years; women 48.8%) were included. Overall, in-hospital mortality was 12.9%. The most prevalent CVD was arterial hypertension (56.1%), followed by hyperlipidemia (27.4%), diabetes mellitus (DM) (25.7%), coronary artery disease (16.8%), heart failure (HF) (10.3%), atrial fibrillation (13.5%), and stroke (8%). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs/ARBs) were used in 25.0% of patients, ß-blockers in 40.7%, statins in 15.6%, and antiplatelet therapy in 19.9%. Age over 65 years (odds ratio [OR], 6.4; 95% CI, 4.3-9.6), male sex (OR, 1.4; 95% CI, 1.1-2.0), pre-existing DM (OR, 1.5; 95% CI, 1.1-2.1), and HF (OR, 2.3; 95% CI, 1.5-3.5) were independent predictors of in-hospital death, whereas treatment with ACEIs/ARBs (OR, 0.4; 95% CI, 0.3-0.6), ß-blockers (OR, 0.6; 95% CI, 0.4-0.9), statins (OR, 0.5; 95% CI, 0.3-0.8), or antiplatelet therapy (OR, 0.6; 95% CI: 0.4-0.9) was associated with lower risk of death. CONCLUSIONS: Among cardiovascular risk factors and diseases, HF and DM appeared to increase in-hospital COVID-19 mortality, whereas the use of cardiovascular drugs was associated with lower mortality.

Use of sensor-augmented insulin pump in patient with diabetes and cystic fibrosis: evidence for improvement in metabolic control.

Cystic fibrosis-related diabetes (CFRD) is a frequent complication of cystic fibrosis. We report the significant improvement of diabetes control and quality of life in a CFRD patient using the sensor-augmented insulin pump. The system gives the patient the highest degree of flexibility, which is required in CFRD since food intake and activity levels vary widely from day to day, depending on the rapid changes of health status.

Risk of macrosomia remains glucose-dependent in a cohort of women with pregestational type 1 diabetes and good glycemic control.

Macrosomia risk remains high in type 1 diabetes (T1DM) complicated pregnancies. A linear relationship between macrosomia risk and glycated hemoglobin A1c (HbA1c) was described; however, low range of HbA1c has not been studied. We aimed to identify risk factors and examine the impact of HbA1c on the occurrence of macrosomia in newborns of T1DM women from a cohort with good glycemic control. In this observational retrospective one-center study we analyzed records of 510 consecutive T1DM pregnancies (1998-2012). The analyzed group consisted of 375 term singleton pregnancies. We used multiple regression models to examine the impact of HbA1c and self-monitored glucose in each trimester on the risk of macrosomia and birth weight. The median age of T1DM women was 28 years, median T1DM duration-11 years, median pregestational BMI-23.3 kg/m2. Median birth weight reached 3520 g (1st and 3rd quartiles 3150 and 3960, respectively) at median 39 weeks of gestation. There were 85 (22.7 %) macrosomic (>4000 g) newborns. Median HbA1c levels in the 1st, 2nd, and 3rd trimester were 6.4, 5.7, and 5.6 %. Third trimester HbA1c, mean fasting self-monitored glucose and maternal age were independent predictors of birth weight and macrosomia. There was a linear relationship between 3rd trimester HbA1c and macrosomia risk in HbA1c range from 4.5 to 7.0 %. Macrosomia in children of T1DM mothers was common despite excellent metabolic control. Glycemia during the 3rd trimester was predominantly responsible for this condition.

Changes in preconception treatment and glycemic control in women with type 1 diabetes mellitus: a 15­year single­center follow­up.

INTRODUCTION    Pregnancy in women with type 1 diabetes mellitus (T1DM) is associated with higher risk of complications. Strict glycemic control before conception reduces the risk of unfavorable outcomes. OBJECTIVES    The aim of the study was to assess changes in clinical characteristics, preconception treatment, and glycemic control of women with T1DM at the first antinatal visit. PATIENTS AND METHODS    We analyzed the records from the first antenatal visit of 524 women with T1DM in the years 1998-2012. The follow­up period was divided into 3 5­year periods. RESULTS    Differences in the age of patients between the 3 follow­up periods were observed (28.2 ±5.7 years for 1998-2002; 27.3 ±4.5 years for 2003-2007; and 29.4 ±4.8 years for 2008-2012; P <0.0001). The number of women planning pregnancy did not change and reached 32.1% in the first, 44.4% in the second, and 40.4% in the third period (P = 0.2). The use of rapid­acting insulin analogues increased from 2.6% to 46.5% and then to 95.6% (P <0.001). The rate of therapy with personal insulin pumps before pregnancy increased from 4.6% in the first, through 23.5% in the second, to 33.3% in the third period (P <0.001). Over the subsequent periods, we observed a decrease in hemoglobin A1c (HbA1c) levels at the first antenatal visit (from 7.4% ±1.6%, through 6.9% ±1.4%, to 7.0% ±1.4%; P = 0.06), as well as a decrease in HbA1c levels between the subgroups of women planning pregnancy (6.8% ±1.4%, 6.6% ±1.2%, and 6.1% ±0.8%, P = 0.015). CONCLUSIONS    In the years 1998-2012, an increase in the use of insulin analogues and personal insulin pumps by women with T1DM before conception was observed, and these changes were accompanied by a slight improvement in glycemic control, particularly among women planning pregnancy. The percentage of women planning pregnancy did not change during the follow­up.

Medical care of pregnant women with type 1 diabetes: current guidelines and clinical practice.

The prevalence of all types of diabetes mellitus is increasing worldwide. Diabetes is a common metabolic complication of pregnancy. For many years, pregnancy complicated by type 1 diabetes was associated with a particularly poor prognosis, and while this has changed dramatically over the last 2 decades, a lot has yet to be done. The continuous relationship between the maternal glucose level and the prevalence of pregnancy complications is well­documented. The list of outcomes includes congenital malformations, stillbirths, neonatal mortality, macrosomia, hypoglycemia, and many others. Several new therapeutic and monitoring tools have become available over the recent years, for example, short- and long­acting insulin analogs, personal pumps, and continuous glucose monitoring systems. Interestingly, pregnancy planning and preconception education proved to be particularly effective in improving glycemic control in type 1 diabetic women and achieving therapeutic goals recommended by clinical guidelines. This resulted in the reduction of some maternal and neonatal pregnancy outcomes reported from various populations, but despite this remarkable progress the prevalence of the most common complication, neonatal macrosomia, is still substantially higher than in the newborns of mothers without diabetes. The likely causes of this phenomenon are short episodes of hyperglycemia, particularly postprandial ones, liberal diet, maternal obesity, and substantial weight gain during pregnancy - these potential reasons should be addressed in clinical practice. In the future, new therapeutic devices, such as close­loop insulin pumps, may help further improve the prognosis in pregnant women with type 1 diabetes.

Evaluation of the prevalence of metabolic obesity and normal weight among the Polish population.

INTRODUCTION: In the 1980s, the idea evolved that some individuals with normal weight (Metabolically Obese, Normal-Weight), who probably have increased abdominal fat, have metabolic disturbances related to obesity. This observation initiated the concept of the metabolically obese but normal-weight syndrome (MONW). Since then, there have been only a few studies in non-obese subjects. MONW men and women should be regarded as at high risk for cardiovascular disease. MATERIAL AND METHOD: A group of 854 randomly chosen non-obese men and women, 20-40 years of age, was selected from three different areas of Poland - Szczecin, Krakow and Wroclaw. All subjects were interviewed and underwent physical examination, anthropometric measurements (waist circumference, hip circumference, BMI and WHR) as well as densitometry (total body DPX, total fat, android/gynoid deposit). Serum level of fasting glucose and insulin, indices of insulin sensibility (QUICKI) and insulin resistance (HOMA, FIRI), total cholesterol, triglycerides and HDL-C were measured using commercially available kits. LDL-C level was calculated using Friedewald's formula. RESULTS: The total amassed fatty tissue and its android deposit was found to be significantly greater in MONW men and women. MONW women were found to exhibit increased levels of triglycerides and LDL-C but lower levels of HDL-C. In women with excess abdominal fat (EAF), fasting glucose and insulin levels, HOMA and FIRI were considerably higher, while QUICKI was lower. Triglyceride and LDL-C levels were also higher while HDL-C levels were lower. In men with EAF, increased levels of total cholesterol and LDL-C were confirmed. CONCLUSIONS: The occurrence of MONW is contingent upon the diagnosis criterion and increases when the criterion represents the value of HOMA - 21.76% in women and 31.42% in men. The frequency of MONW occurrence is lower when the criterion for abdominal fat content limit is used, amounting to 15.78% in women and 7.83% in men.

The dual-wave bolus feature in type 1 diabetes adult users of insulin pumps.

One of the attributes of CSII (continuous subcutaneous insulin infusion) is its ability to tailor prandial insulin delivery to the composition of a meal and anticipated glycemic effects. The dual-wave bolus (DWB) is a tool implemented in contemporary insulin pumps that delivers a combination of an instant insulin bolus followed by a square bolus (SB) infused over several hours. We assessed the effectiveness of DWB in 56 adult patients with type 1 diabetes (T1DM) who were on continuous subcutaneous insulin infusion via insulin pump for at least 2 years. We divided patients into frequent (DWB+, n = 32) and infrequent (DWB-, n = 24) DWB users (>20% vs. <20% of daily bolus dose delivered as SB). CSII implementation resulted in a decrease of adjusted HbA1c level by 0.80% (95% CI 0.67-0.93, P < 0.0001) and adjusted mean glycemia by 18.4 mg/dl (95% CI 15.3-21.4, P < 0.0001) in the whole cohort within the first year of observation. It was sustained in the second year, but without further improvement. Frequent DWB use was associated with male sex (59% vs. 17%, p = 0.001) and shorter duration of T1DM (3.4 vs. 11.3 yrs, p < 0.0001), but not with patients' age (25.7 vs. 27.0 years, P = 0.6). DWB+ patients improved their HbA1c by 0.45% more (95% CI 0.20-0.71, P = 0.0009) than DWB- individuals. In conclusion, DWB might be a tool potentially helping to improve glycemic control in T1DM adult users of insulin pumps. Male patients and those with a shorter duration of diabetes seem to use it more willingly.

Insulin pump therapy is equally effective and safe in elderly and young type 1 diabetes patients.

OBJECTIVES: It is generally accepted that in adult type 1 diabetes patients (T1D) continuous subcutaneous insulin infusion (CSII) via a personal pump is more effective than the multiple daily injections (MDI) model. However, it is not clear whether all age groups of adult T1D patients may equally benefit from CSII therapy. We aimed to compare the glycemic control and use of selected pump tools in T1D subjects using CSII over the age of 50 (50+ T1D) with patients younger than 50 years of age. METHODS: The last available insulin pump/blood glucose meter downloads and last available HbA1c levels of 124 adult T1D subjects using CSII were reviewed. We divided our cohort into two subgroups: 50+ T1D patients (n = 13) and younger patients (n = 111). RESULTS: There were no differences in glycemic control achieved with CSII treatment in 50+ T1D patients vs. younger subjects. HbA1c levels were 7.01 ± 0.67% and 7.34 ± 1.24% (p = 0.46), and the mean glycemia based on glucometer downloads was 141.8 ± 17.7 mg/dl and 150.8 ± 35.7 mg/dl (p = 0.69), respectively. Also, there were no differences with respect to the use of important personal pump options and tools. CONCLUSION: In conclusion, insulin pump therapy appears to be effective and safe in T1D patients regardless of age.

Glycemic control and pregnancy outcomes in women with type 2 diabetes from Poland. The impact of pregnancy planning and a comparison with type 1 diabetes subjects.

The number of pregnancies complicated by type 2 diabetes mellitus (T2DM) is growing; however, their clinical characteristics remain incomplete. We aimed to assess clinical characteristics, glycemic control, and selected pregnancy outcomes in pregestational T2DM from Poland and to compare them with those of T1DM. We analyzed 415 consecutive singleton pregnancies; among them, there were 70 women with T2DM and 345 with T1DM. As compared to T1DM patients, women with T2DM were older (mean age 33.1 years vs. 27.8, respectively), heavier before pregnancy (mean BMI 30.8 kg/m² vs. 23.9), and had a shorter duration of diabetes (mean 3.3 years vs. 11.4); ( P<0.0001 for all comparisons). The gestational age at the first visit was higher in T2DM (mean 11.4 weeks vs. 8.6; P=0.0004). Nevertheless, they had better glycemic control in the first trimester (mean HbA1c 6.2% vs. 7.0; P=0.003); in subsequent months, the differences in HbA1c were no longer significant. T2DM women gained less weight during pregnancy (mean 9.9 kgs vs. 14.1; P<0.0001). The proportion of miscarriages (10.0 vs. 7.3%; P=0.32), preterm deliveries (12.7 vs. 17.8%; P=0.32), combined infant deaths, and congenital malformations were similar in both groups (9.5 vs. 8.8%; P=0.4) as was the frequency of caesarean sections (58.7 vs. 64.1%; P=0.30). Macrosomic babies were more than twice less frequent in T2DM and the difference reached borderline significance (7.9 vs. 17.5%, P=0.07). Pregnancy planning in T2DM had a significant impact on HbA1c in the first trimester (5.7 vs. 6.4% in the planning vs. the not planning group, P=0.02); the difference was not significant in the second and third trimester. T2DM women had better glycemic control in the first trimester than T1DM subjects and gained less weight during pregnancy. This could have been the reason for the slightly lower number of macrosomic babies but did not affect other outcomes. In T2DM, pregnancy planning had a beneficial glycemic effect in the first trimester.

Dipeptidyl peptidase-IV inhibitors are efficient adjunct therapy in HNF1A maturity-onset diabetes of the young patients--report of two cases.

BACKGROUND: In HNF1A maturity-onset diabetes of the young (MODY), sulfonylurea (SU) is the first-line treatment. Over time, such therapy fails, and additional treatment is required. Dipeptidyl peptidase IV (DPP-IV) inhibitors are new agents that lower blood glucose by prolonging the activity of circulating incretins. METHODS: We applied DPP-IV inhibitors in two HNF1A MODY patients whose earlier therapeutic regimen included SU. RESULTS: Case 1, a 39-year-old woman, a carrier of the ArgR171X HNF1A mutation, with a 7-year history of diabetes was on 160 mg of gliclazide and 2,000 mg of metformin. Her initial hemoglobin A1c (HbA1c) level was 7.2%, while the mean glucose level on the CGMS((R)) (Medtronic, Northridge, CA) record was 162 mg/dL. Sitagliptine, in a dose of 100 mg/day, was added to the previous treatment. Case 2, a 62-year-old woman, a carrier of the IVS7nt-6G>A mutation, with a 41-year history of diabetes was treated with 240 mg/day gliclazide and 6 IU of insulin/day. Her initial HbA1c was 8.8%, and average glycemia reached 172 mg/dL. In her case, we started the combined therapy with 50 mg of vildagliptine twice daily. Patients were reexamined after 3 months, and HbA1c fell to 6.3% in both subjects. Similarly, significant improvement in glycemic control on CGMS was observed as the average glycemia decreased to 114 mg/dL and 134 mg/dL in Case 1 and Case 2, respectively. No episodes of hypoglycemia or other side effects were recorded. As intravenous glucose tolerance tests (IVGTTs) were performed before and after DPP-IV implementation, we were able to assess their impact on insulin secretion under fasting conditions. We saw a substantial rise in insulin level increment during IVGTT (by 9.8 and13.4 mIU/L in Case 1 and Case 2, respectively). CONCLUSIONS: DPP-IV inhibitors may be an effective tool of combined therapy in HNF1A MODY, and they seem to improve beta-cell function under fasting conditions.

Glycemic control and selected pregnancy outcomes in type 1 diabetes women on continuous subcutaneous insulin infusion and multiple daily injections: the significance of pregnancy planning.

BACKGROUND: Two regimens are used to achieve excellent glycemic control during pregnancy in type 1 diabetes mellitus (T1DM): continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI). We assessed their efficacy and safety and the effect of pregnancy planning. METHODS: We examined 269 pregnant T1DM women: 157 treated with MDI (MDI group), 42 with CSII (CSII group), and 70 who switched from MDI to CSII in the first trimester (MDI/CSII group). There were 116 women who planned pregnancy: 58 in the MDI group, 38 in the CSII group, and 20 in the MDI/CSII group. The estimated differences in glycemic control and maternal and fetal outcomes were adjusted for baseline characteristics. RESULTS: Mean glycated A1c (HbA1c) in the first trimester in the whole group was 6.9%, and the women differed depending on whether they planned pregnancy or not (P < 0.0001). A multiple regression model showed an average difference of about 0.9% in favor of pregnancy planning, with no interaction between the planning and treatments. In the second trimester, HbA1c decreased to a mean value of 5.8%, with improvement of HbA1c across all treatments: by 1.5% in not-planning and 0.9% in planning women. Despite greater improvement, not-planning women still had a higher HbA1c (by 0.3%, P = 0.05). In the third trimester, there was no further significant changes; nevertheless, women who planned pregnancy still had a lower HbA1c (by 0.5%, P = 0.02). There were 14 malformations, stillbirths, and perinatal infant deaths in the not-planning versus five in the planning group (P = 0.07). Patients in the CSII group had a 2 kg greater weight gain compared to the MDI group (15.0 kg vs. 13.0 kg; P = 0.005). CONCLUSIONS: In pregnancy with T1DM, both MDI and CSII can provide excellent glycemic control. Pregnancy planning has a beneficial effect on glycemic control, independent from the therapy model. CSII seems to predispose to a larger weight gain in mothers.

Visceral obesity and hemostatic profile in patients with type 2 diabetes: the effect of gender and metabolic compensation.

BACKGROUND: Type 2 diabetes (T2DM) patients are characterized by a very high risk of cardiovascular diseases. Among the factors that are responsible for this phenomenon are abdominal obesity and hemostatic abnormalities. AIM OF THE STUDY: To examine the association of the markers of coagulation and fibrinolysis with the parameters of abdominal obesity and metabolic compensation in T2DM patients. METHODS: 46 T2DM patients participated in the study: 24 men (mean age 61.1 +/- 7.9 years) and 22 postmenopausal women (mean age 62.6 +/- 8.7 years). In each patient the content and distribution of fatty tissue was measured by a dual energy X-ray absorptiometry method (DEXA). The central abdominal fat/gynoid hip fat (CAF/GF) ratio was calculated. The following hemostatic parameters were measured: fibrinogen (Fb), factor VII (fVII), antithrombin III (ATIII), C protein (pC), tissue plasminogen activator inhibitor (PAI-1) and alpha 2 antiplasmin (alpha2 AP). In addition, the biochemical indices of metabolic compensation were measured: HbA1c, glucose levels and lipids. RESULTS: Patients of both genders were divided according to median CAF/GF ratio. The activity of PAI-1 was significantly higher in women with CAF/GF ratio >or= 0.88 as compared to those with CAF/GF < 0.88 (2.64 +/- 1.28 vs. 1.61 +/- 0.27 U/ml, p < 0.05). The activity of ATIII was significantly lower in men with CAF/GF ratio >or= 1.17, as compared to those with CAF/GF < 1.17 (105.10 +/- 10.02 vs. 113.42 +/- 10.72 %, p < 0.05). There was a significant correlation between the CAF/GF ratio and the activity of PAI-1 in women (r = 0.30, p < 0.05). In addition, in men the CAF/GF ratio was negatively correlated with ATIII activity (r = -0.44, p < 0.05). Multiple stepwise regression analysis demonstrated independent association between the CAF/ GF ratio and the activity of PAI-1 (p < 0.001), and between the CAF/GF ratio and the activity of alpha2 AP (p < 0.01). There was an independent association between the concentration of HbA1c and the concentration of Fb (p < 0.001) and between triglycerides and the activity of fVII (p < 0.01). CONCLUSIONS: The results of our study show that the patients with T2DM and with higher markers of abdominal obesity measured by DEXA show fibrinolysis impairment and thrombinogenesis elevation compared to those with lower abdominal obesity markers. Independent factors determining hypercoagulation also include metabolic control and lipids. Hemostatic disorders place subjects with diabetes and abdominal obesity at risk of developing vascular complications.
