Primary response in GHD children treatment as a predictor for long-term therapy effectiveness therapy effectiveness.

INTRODUCTION: Short stature in growth hormone deficiency (GHD) can be treated with recombinant human growth hormone (rhGH), which is proven to be both safe and effective. However, a considerable number of patients does not achieve satisfying therapy outcomes. AIM OF THE STUDY: To evaluate the predictive effect of height increase in the first year of rhGH treatment on long-term therapy outcomes. MATERIAL AND METHODS: 165 short-stature children (mean age 10.72 ±3.33 years; 63% males), diagnosed with GHD, treated with rhGH for at least one year (mean follow-up 4.32 ±1.80 years), divided into 2 groups according to the change in height standard deviation score (SDS) after the first year of rhGH treatment: good responders (GR) and poor responders (PR). Then, in one-year intervals, patient's chronological age, bone age, height, weight, insulin-like growth factor level, and rhGH dose were all assessed. RESULTS: In the GR group, mean height velocity SDS up to five years of observation was 1.19 ±0.41/year and in the PR group 0.59 ±0.38/year. The differences were statistically significant (p < 0.05). CONCLUSIONS: The primary response to the rhGH treatment in GHD children seems to be a good predictor for long-term therapy outcomes.

Does Hashimoto's Thyroiditis Increase the Risk of Cardiovascular Disease in Young Type 1 Diabetic Patients?

Background: Immunological and hormonal disorders have undoubted influence on the development of atherosclerotic process. Autoimmune diseases accompanying type 1 diabetes (T1D) may additionally accelerate atherosclerosis progression and increase the risk of cardiovascular events in the future. The influence of subclinical hypothyroidism on the cardiovascular system, in particular, has recently aroused great interest. The aim of our study was to assess intima-media thickness (cIMT) of common carotid arteries and the occurrence of classical atherosclerosis risk factors together with selected new biomarkers of cardiovascular diseases in young patients with type 1 diabetes mellitus coexisting with Hashimoto's disease (HD). Patients and Methods: The study included 50 adolescents and young adults with T1D with mean age 17.1 ± 3 years, with mean diabetes duration of 10.5 ± 3.3 years, including 20 patients with diagnosed HD: T1D and HD(+), and 30 patients with no additional diseases: T1D and HD(-). Twenty-two healthy, age-matched volunteers formed control group (C). We analyzed mean HbA1c value from all years of disease, BMI, blood pressure, lipids, new biomarkers of atherosclerosis (hsCRP, adiponectin, myeloperoxidase, NT-proBNP peptide, vitamin D), and cIMT of common carotid arteries. Results: In the group of patients with T1D and HD(+), significantly higher BMI was found: 23.3 ± 4.4 vs. 21.28 ± 2.9 in group HD(-) and 19.65 ± 2.4 kg/m2 in group C (p = 0.003), and higher waist circumference: 79 ± 10.9 vs. 75.10 ± 7.6 in group HD(-) vs. 69.0 ± 7.4 cm in group C (p < 0.001). The mean value of HbA1c was higher in group T1D and HD(+): 8.8% than in group HD(-): 8.1% (p = 0.04). Significantly higher concentration of hsCRP and lower vitamin D were observed in T1D and HD(+) in comparison to T1D and HD(-) and the control group. The IMT index in the HD(+) group was 0.46 ± 0.05 mm and was comparable to the HD(-) group but significantly higher than in healthy controls: 0.41 ± 0.03 mm (P < 0.05). Conclusions: Young patients with type 1 diabetes mellitus and with coexisting Hashimoto's thyroiditis have a higher BMI, a higher waist circumference, and a higher HbA1c value, which altogether may cause faster development of macroangiopathy in the near future. Additional risk for cardiovascular disease may result from low vitamin D and increased hsCRP concentration in this group of patients. Coexistence of Hashimoto's thyroiditis did not significantly affect the cIMT value in the studied population.

Symptomatic hyponatremia during the diabetic ketoacidosis in 5 years old child with new onset diabetes - own experience.

Hyponatremia is the one of the most common electrolyte abnormality in the clinical practice and is associated with increased morbidity and mortality. Decreased serum sodium levels are occasionally observed in patients with diabetes mellitus, especially in those, who pre-sent with the diabetic ketoacidosis. It can develop at the each stage of a treatment, as a complication of hyperglycemia and intensity of the therapy, but also the other underlying causes should be consider. In this report we present a patient with symptomatic hyponatremia in the new diagnosed patient with type 1 diabetes mellitus.

Seasonal Variation in Month of Diagnosis of Polish Children with Type 1 Diabetes - A Multicenter Study.

AIM: The seasonal variation of incidence of type 1 diabetes (T1D) theory supports the hypothesis that environmental factors play a role in the onset of the disease. The aim of this study is to assess seasonality of month of diagnosis in children with T1D in Poland. MATERIAL AND METHODS: the study group consisted of 2174 children from eastern and central Poland diagnosed with T1D between 2010 and 2014. Analysis was performed in different age groups, based on place of residence (rural/urban area) and depending on sex. RESULTS: We noted significant seasonality in the incidence of T1D with a peak in diagnosis of diabetes in January and the minimum rate in June. A total of 423 (19%) children were diagnosed in the warmest months (June to August with a mean temperature of 16.8°C) compared to 636 (29%) recognised in the coldest months (December to February with a mean temperature of -1.6°C), OR 0.57 95%CI [0.51-0.67], p<0.0001. We noted a more flat seasonal pattern in children 0-4 years of age compared with subjects 5-17 years old with a week correlation of trend comparison between both groups, r=0.69, p=0.001. Similar seasonal variation in the incidence of T1D was noted in children from urban and rural setting. For girls, seasonal pattern peaks were observed one month earlier as compared to boys. CONCLUSIONS: Seasonal variation in incidence of T1D diagnosis of Polish children supports the role of different environmental factors in diabetes onset. The majority of children were diagnosed with diabetes in autumn and winter.

Factors associated with preservation of C-peptide levels at the diagnosis of type 1 diabetes.

AIMS: The level of C-peptide can identify individuals most likely to respond to immune interventions carried out to prevent pancreatic ß-cell damage. The aim of the study was to evaluate factors associated with C-peptide levels at type 1 diabetes (T1D) diagnosis. METHODS: This study included 1098 children aged 2-17 with newly recognized T1D. Data were collected from seven Polish hospitals. The following variables were analyzed: date of birth, fasting C-peptide, HbA1c, sex, weight, height, pH at diabetes onset. RESULTS: A correlation was observed between fasting C-peptide level and BMI-SDS (p = 0.0001), age (p = 0.0001), and HbA1c (p = 0.0001). The logistic regression model revealed that fasting C-peptide ≥0.7 ng/ml at diabetes diagnosis was dependent on weight, HbA1c, pH and sex (p < 0.0001). Overweight and obese children (n = 124) had higher fasting C-peptide (p = 0.0001) and lower HbA1c (p = 0.0008) levels than other subjects. Girls had higher fasting C-peptide (p = 0.036) and higher HbA1c (p = 0.026) levels than boys. CONCLUSION: Obese and overweight children are diagnosed with diabetes at an early stage with largely preserved C-peptide levels. Increased awareness of T1D symptoms as well as improved screening and diagnostic tools are important to preserve C-peptide levels. There are noticeable gender differences in the course of diabetes already at T1D diagnosis.

Epidemiology of type 1 diabetes in Polish children: A multicentre cohort study.

BACKGROUND: The incidence of childhood type 1 diabetes (T1D) varies greatly between populations, and the estimates and/or predictions of the rates would aid in adequate planning of health care resources. The study's aim was to assess the incidence of T1D in the paediatric population of eastern and central Poland. METHODS: In this cohort study covering the period from January 2010 to December 2014, data were collected for children and adolescents below 18 years of age with newly diagnosed T1D living in eastern and central Poland. A total of 2174 children were included in the analysis. The population estimates were from the Central Statistical Office of Poland. RESULTS: Overall, the annual incidence of T1D increased from 12.84/100,000 in 2010 to 18.46/100,000 in 2014 with the incidence rate (IR) ratio of 1.5 (an increase in the IR by 12.7% per year over 5 years). The lowest increase in the IR by 7.1% per year was seen in 15 to 17-year-olds. In the urban population (age 0-17 years), the overall incidence rate was significantly higher than in subjects from rural communities (P < .02). The incidence of T1D in rural areas was significantly higher (p = .004) in voivodeships of higher population density. Such dependence was not observed in urban areas. CONCLUSIONS: The incidence of T1D in children living in eastern and central Poland increased 1.5-fold over the 5-year observation period with the highest rise in 10 to 14-year-olds and significantly higher rates in urban children compared with their peers living in rural areas.

High incidence of diabetic ketoacidosis at diagnosis of type 1 diabetes among Polish children aged 10-12 and under 5 years of age: A multicenter study.

AIM: Despite its characteristic symptoms, type 1 diabetes (T1D) is still diagnosed late causing the development of diabetic ketoacidosis (DKA). The aim of this study was to estimate the incidence of DKA and factors associated with the development of acidosis at T1D recognition in Polish children aged 0-17. METHODS: The study population consisted of 2100 children with newly diagnosed T1D in the years 2010-2014 in 7 hospitals in eastern and central Poland. The population living in these areas accounts for 35% of the Polish population. DKA was defined as a capillary pH < 7.3, blood glucose > 11 mmol/L. The analyzed data included age, sex, diabetes recognition, pH, glycated hemoglobin (HbA1c), fasting C-peptide, and body mass index standard deviation score (BMI-SDS). RESULTS: We observed DKA in 28.6% of children. There were 2 peaks in DKA occurrence: in children <5 years of age (33.9%) and aged 10-12 (34%). The highest incidence of DKA was noted in children aged 0-2 (48.4%). In the group with DKA, moderate and severe DKA occurred in 46.7% of children. Girls and children <2 years of age were more prone to severe DKA. The multiple logistic regression analysis showed the following factors associated with DKA: age (P = .002), fasting C-peptide (P = .0001), HbA1c (P = .0001), no family history of T1D (P = .0001), and BMI-SDS (P = .0001). CONCLUSIONS: The incidence of DKA is high and remained unchanged over the last 5 years. Increasing the awareness of symptoms of DKA is recommended among children <5 years of age (especially <2 years of age) and aged 10-12. Children <2 years of age and girls were at the highest risk of severe DKA.

[Carotid artery intima-media thickness (cIMT) in young type 1 diabetic patients in relation to comorbid additional autoimmune diseases and microvascular complications]. / Ocena grubosci kompleksu intima-media (cIMT) tetnicy szyjnej wspólnej u mlodych pacjentów z cukrzyca typu 1 w zaleznosci od towarzyszacych chorób autoimmunizacyjnych oraz powiklan naczyniowych cukrzycy.

INTRODUCTION: Atherosclerosis, which is the cause of diseases of the cardiovascular system, and frequent and serious complications of type 1 diabetes (T1DM), has an autoimmune origin. Some diseases of this type, as rheumatoid arthritis, but also Hashimoto thyroiditis or celiac disease are associated with a higher incidence of heart disease. So far no studies evaluated the preclinical phase of development of atherosclerosis (cIMT) in young patients with T1DM and the comorbid additional autoimmune diseases. AIM OF THE STUDY: was evaluation of cIMT (carotid intima media thickness) carotid arteries and the risk factors of atherosclerosis in young patients with type 1 diabetes according to the comorbid autoimmune diseases and a comparison group of patients with known vascular complications and a group of healthy people. PATIENTS AND METHODS: The study involved a group of 90 adolescents and young adults with T1DM in middle age 17,1±3years, with an average disease duration of 10,5±3,3 years. Diabetes patients were divided into 4 groups - diabetes without complications - C, diabetes with celiac disease - CC, diabetes with Hashimoto's thyroiditis - CH, diabetes with vascular complications - CN. The control group (K) consisted of 22 healthy age-matched volunteers. In statistical analysis rated: average A1C of all the years of illness, BMI, blood pressure, lipid values, duration of illness, presence of diabetes complications, daily insulin dose and cIMT thickness of the common carotid artery. RESULTS: cIMT of T1DM patients was significantly higher: 0,470 mm than in healthy: 0,409 mm. In the group with vascular complications of diabetes was found the highest rate of cIMT: 0,501 mm in comparison to the group of diabetes without complications: 0,462 mm, diabetes with celiac disease: 0,462 mm, and diabetes with Hashimoto's thyroiditis: 0,453 mm. HbA1c was highest in the group CN: 9,84±1,5%, compared to CH: 9,04± 1,2%, CC: 8,84±1,8% and C without complications: 8,55±1,2%. BMI was highest in the group CN: 23,3± 4,4kg/m2and CH: 22,6 ± 2,4 kg/m2. It was the same with waist circumference: CN: 79,33± 9,39and CH: 79,2 ± 9,56 cm. Patients with vascular complications were characterized by the higher value of blood pressure and lipids compared to patients with additional autoimmune disease. Coexistence of celiac disease was not associated with a greater value of cIMT and cardiovascular risk factors in young patients with type 1 diabetes. CONCLUSIONS: 1. Increased value of cIMT, and thus increased risk of early disease of the cardiovascular system depends primarily on metabolic compensation and classic risk factors for atherosclerosis. 2. The coexistence of additional autoimmune disease does not significantly affect the value of cIMT in the study population. 3. Young patients with diabetes type 1 and coexisting Hashimoto disease have greater BMI and waist circumference, what can lead to earlier macroangiopathy in the future.

[Selected aspects of the epidemiological analysis of celiac disease and diabetes mellitus type 1 coexistance in children and youth]. / Wybrane aspekty analizy epidemiologicznej wspólwystepowania celiakii i cukrzycy typu 1 u dzieci i mlodziezy.

UNLABELLED: Modern serological tests and changed clinical appearance are the causes of more frequent occurrence of celiac disease (CD) in general population, also in risk groups for instance in patients suffering from diabetes mellitus type 1 (DM t. 1). The aim of the study was to estimate the frequency of CD in patients with DM t. 1 and attempt at evaluation of some factors making to incidence. MATERIAL AND METHODS: It was examined 446 patients (titre of anty-endomysial antibodies (anty EMA), endoscopic biopsy in these with titre > 1OIF). The frequency of CD elevated 5.16%, it was sex and duration of DM t. 1 independent. Children with confirmed CD were younger and earlier suffered from DM t. 1 in comparison with these negative anty EMA. RESULTS: Higher frequency of CD in younger children, who suffered from DM t. 1 to the completion of the fourth year was shown. It wasn't stated the relationship between duration of DM t. 1 and frequency of CD. CONCLUSIONS: This study indicates the necessity to perform serological studies of CD in diabetic patients. Annual screening tests of CD in first fourth years of DM t. 1 in children before the completion of the fourth year of life seem to be justified.

[Estimation of the severity of metabolic disorders in children with newly diagnosed insulin dependent diabetes mellitus (IDDM)]. / Ocena stopnia ciezkosci zaburzen metabolicznych u dzieci z nowo rozpoznana cukrzyca typu 1.

The objective of this study was to estimate the severity of metabolic disorders at onset in children with insulin dependent diabetes mellitus (IDDM). Biochemical results taken at onset of IDDM were analysed in 158 children on their admission. Metabolic acidosis was found in 37.97% of those and ketoacidosis was confirmed in 18.99% children. Mean values of biochemical parameters are similar to those reported in the others European countries. The most severe changes of the acid-base balance parameters were observed in youngest children (1-4 y.o) living in the rural areas (pH, 7.22, HCO3- 10.2 mmol/l, BE - 16.06 mmol/l, p=0.05); this should suggest that those children are watchfully observed and IDDM should be always be considered as a possible cause of any alarming symptoms which occur.
