Uric acid and cardiometabolic risk by gender in youth with type 1 diabetes.

The aim of this study was to investigate the association between uric acid (UA) and cardiometabolic risk factors (CMRFs) by sex in youth with type 1 diabetes (T1D). Retrospective data collected from 1323 children and adolescents (5-18 years; 716 boys) with T1D recruited in 9 Italian Pediatric Diabetes Centers were analyzed. CMRFs included UA, HbA1c, blood pressure (BP), cholesterol (TC), HDL, triglycerides (TG), neutrophils (N) and lymphocytes (L) count, glomerular filtration rate (eGFR) (calculated using Schwartz-Lyon equation). In boys, we found a higher age, daily insulin dose, TG, TG/HDL ratio, TC/HDL ratio, systolic BP, N/L ratio and lower HDL, and eGFR across UA tertiles (p = 0.01-0.0001). Similar results were found in girls but not for TG and systolic BP. In boys, the odds ratio (OR) of high levels of TG/HDL ratio, TC/HDL ratio, BP and mildly reduced eGFR (MRGFR) increased for 0.5 mg/dL of UA. Instead, in girls an increased levels of 0.5 mg/dL of UA were associated with high OR of TC/HDL ratio, N/L ratio and MRGFR. Uric acid may represent a useful marker for identifying youth with T1D at high cardiometabolic risk, and this association appears to vary by sex.

A comparative study on the incidence of type 1 diabetes mellitus between children of North African migrants and Italian children in Emilia-Romagna region, Italy.

In the last few decades, many studies have reported an increasing global incidence of type 1 diabetes. Studies on migrant populations have underlined the importance of both environmental and genetic factors. AIMS: Evaluate the incidence of type 1 diabetes in North African vs Italian children aged 0-14 years from 1 January 2015, to 31st December 2018, in Emilia-Romagna region, Italy. METHODS: Clinical and epidemiological data about childhood onset type 1 diabetes in Emilia Romagna region were retrospectively collected by the regional centers of pediatric diabetology and matched using 3 different data sources. RESULTS: 365 new cases were diagnosed. Total cumulative incidence was 15.4/100,000/year. North African cases showed a cumulative incidence of 53.8/100,000/year, statistically significant compared to cumulative incidence of the Italian cases alone 13.1/100,000/year (p value < 0.001). The annual incidence did not differ in the 4 years for both groups.  Conclusion: The incidence of type 1 diabetes in the pediatric age (0 14 years) was significantly higher in the North African population than in the Italian one, suggesting that a mix of genetic and environmental factors may have caused the increase in newly diagnosed cases. WHAT IS KNOWN: • The incidence of type 1 diabetes largely varies worldwide. • Study on immigrants helped to better understand the interplay role between genetics and environment. WHAT IS NEW: • This is the first study focused on the incidence of children and adolescents of North African migrants in Italy. • The incidence of children and adolescents of North African migrants in Emilia Romagna region, Italy, seems to be higher than that reported in the host countries, and, above all, than that reported in highest-incidence countries in Europe and in the world.

Improvement in glycaemic control in paediatric and young adult type 1 diabetes patients during COVID-19 pandemic: role of telemedicine and lifestyle changes.

BACKGROUND AND AIM: COVID-19 pandemic determined a profound impact in everyday life and in routine follow-up of patients with type 1 diabetes (T1D). In this context, telemedicine represented an important tool to guarantee a regular care for these patients. Aim of our work was to assess metabolic control before and after lockdown in the cohort of T1D patients followed-up by our Service, to evaluate the impact of restrictive measures and of disease management through telemedicine. METHODS: This is a retrospective observational study. Subjects were enrolled among children, adolescents and young adults affected by T1D and followed at the Regional Paediatric Diabetology Centre of the University-Hospital of Parma, Italy. We collected data about age, gender, ethnicity, anthropometric measurements, duration of disease, type of blood glucose monitoring used, type of insulin administration, daily insulin requirement and metabolic control, assessed using capillary HbA1c. RESULTS: We enrolled 139 patients, mean age 13.9 years. During lockdown, we reported significantly more contacts through telemedicine between patients and medical team. Global glycol-metabolic control significantly improved, without differences in daily insulin requirement. Patients with a previous poor-controlled diabetes showed a greater improvement. Finally, mean weekly hours of physical activity decreased significantly, without worsening in BMI z-score. CONCLUSIONS: Our results show a global improvement in mean HbA1c, with a stronger result for patients with a previous non satisfactory control. In our setting, despite regulatory rules and physical and logistic limitations related to pandemic, no worsening of metabolic control has been shown for patients with type 1 diabetes.

Albuminuric and non-albuminuric reduced eGFR phenotypes in youth with type 1 diabetes: Factors associated with cardiometabolic risk.

BACKGROUND AND AIM: Albuminuria and reduced eGFR are hallmarks of Diabetic Kidney Disease in adults. Our aim was to analyze factors associated with albuminuric and non-albuminuric mildly reduced eGFR phenotypes in youths with type 1 diabetes. METHODS AND RESULTS: This multicenter cross-sectional study included 1549 youths (age 5-17 years) with type 1 diabetes enrolled at 14 Italian Pediatric Diabetes Centers. Albuminuria, creatinine, glycosylated hemoglobin (HbA1c), lipids, blood pressure (BP), neutrophils (N) and lymphocytes (L) count were analyzed. Uric acid (UA) was available in 848 individuals. Estimated GFR (eGFR) was calculated using bedside Schwartz's equation. The sample was divided in three phenotypes: 1) normoalbuminuria and eGFR ≥90 mL/min/1.73 m2 (reference category, n = 1204), 2) albuminuric and normal GFR phenotype (n = 106), 3) non-albuminuric mildly reduced GFR (MRGFR) phenotype (eGFR 60-89 mL/min/1.73 m2, n = 239). Albuminuric and non-albuminuric reduced eGFR phenotypes were significantly associated with autoimmune thyroiditis (P =0.028 and P=0.044, respectively). Albuminuric phenotype showed high risk of high HbA1c (P=0.029), high BP (P < 0.001), and low HDL-C (P =0.045) vs reference category. Non-albuminuric MRGFR phenotype showed high risk of high BP (P < 0.0001), low HDL-C (P =0.042), high Triglycerides/HDL-C ratio (P =0.019), and high UA (P < 0.0001) vs reference category. CONCLUSION: Non albuminuric MRGFR phenotype is more prevalent than albuminuric phenotype and shows a worst cardiometabolic risk (CMR) profile). Both phenotypes are associated with autoimmune thyroiditis. Our data suggest to evaluate both albuminuria and eGFR earlier in type 1 diabetes to timely identify young people with altered CMR profile.

COVID19: potential cardiovascular issues in pediatric patients.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-COV 2) has rapidly spread worldwide with increasing hospitalization and mortality rate. Ongoing studies and accumulated data are de- tailing the features and the effects of the new coronavirus disease 19 (COVID 19) in the adult population, and cardiovascular involvement is emerging as the most significant and life-threatening complication, with an in- creased risk of morbidity and mortality in patients with underlying cardiovascular disease. At present, though the limited data on the effects of COVID 19 in pediatric patients, children seem to count for a little proportion of SARS-COV 2 infection, and present with less severe disease and effects However infants and toddlers are at risk of developing critical course. The disease has a range of clinical presentations in children, for which the potential need for further investigation of myocardial injury and cardiovascular issues should be kept in mind to avoid misdiagnosing severe clinical entities. Overlapping with Kawasaki disease is a concern, particularly the incomplete and atypical form. We aim to summarize the initial considerations and potential cardiovascular implications of COVID-19 for children and patients with congenital heart disease.

Diabetic ketoacidosis at type 1 diabetes onset: indirect impact of COVID-19 pandemic.

Reorganization of healthcare resources due to COVID-19 pandemic has led to an unintentional neglect of essential care, especially for paediatric emergencies. This phenomenon has been observed also for type 1 diabetes patients at onset, and surveys from different countries have shown an increased number of diabetic ketoacidosis during lock-down period. We report the case of two patients admitted late at our emergency care service for type-1 diabetes at onset with ketoacidosis, for reasons related to COVID-19 pandemic outbreak. Case report 1: A 5 years old boy, presented with a severe diabetic ketoacidosis, requiring admission in Intensive Care Unit, prolonged intravenous insulin infusion and enteral nutrion via nasogastric tube. Case report 2:  A 10 years old girl presented in the emergency department with a history respiratory distress, due to Kussmaul's breathing, and severe dehydration. Laboratory findings were consistent with a diagnosis of moderate diabetic ketoacidosis. We have further analyzed the experience of our Centre regarding new onset type 1 diabetes patients during lock-down period: we observed a reduction of admissions for type 1 diabetes onset during lock-down period compared to same period of 2019, with a higher prevalence of moderate and severe diabetic ketoacidosis. We conclude highlighting the upcoming necessity, due to the emerging of a 'second wave' of the pandemic, that public opinion and healthcare practitioners provide correct information regarding access to paediatric services, in particular for children with newly onset symptoms, in order to avoid late access to emergency department in critical situations and to prevent avoidable morbidity and mortality.

Report on advances for pediatricians in 2018: allergy, cardiology, critical care, endocrinology, hereditary metabolic diseases, gastroenterology, infectious diseases, neonatology, nutrition, respiratory tract disorders and surgery.

This review reported notable advances in pediatrics that have been published in 2018. We have highlighted progresses in allergy, cardiology, critical care, endocrinology, hereditary metabolic diseases, gastroenterology, infectious diseases, neonatology, nutrition, respiratory tract disorders and surgery. Many studies have informed on epidemiologic observations. Promising outcomes in prevention, diagnosis and treatment have been reported. We think that advances realized in 2018 can now be utilized to ameliorate patient care.

Clinical utility of beta-hydroxybutyrate measurement in the management of physiological ketosis at home in children under 5.

AIM: To verify the possible advantages of 3- ß-hydroxybutyrate (3HB) measurement compared to urinary assay of ketones during an intercurrent disease managed at home. METHODS: Twelve Pediatricians were asked to enroll at least 4 patients aged 3 to 5 years, affected by an intercurrent illness and showing at least one of symptoms reliable to ketosis. Recruited patients were submitted to the simultaneous assay of 3HB in capillary blood and ketones in urine at 3 (T3) and 6 hours (T6) from the first measurement (T0). For urinary and blood ketone detection commercial tests were used. RESULTS: Thirty-eight children (4.36±2.60 years old; 25 boys) were enrolled into the study. At T0 all children showed 3HB levels (1.2-3.2 mmol/L), but only 10 of them (26.3%) associated also urinary ketone bodies (2 to 4+). In response to 3 hour treatment (T3) with a glucose solution, 3HB values decreased in 19 (0,8-1,8 mmol/L) and normalized in 13 children (<0.2 mmol/L); while ketonuria disappeared in only 2 patients, it was confirmed in 8 and appeared (4+) the first time in the remaining 28 children. At T6 3HB levels fell definitively within the normal range in all children, while ketonuria was still present (2+) in 9 patients (23%). The pediatricians reported two limitations about blood 3HB dosage compared to the urinary test: the invasiveness of capillary blood collection, and the cost of supplies for finger pricking, reagent strips and reflectance meter. CONCLUSIONS: 3HB monitor in capillary blood is more effective and clinically more useful in diagnosing and managing of an ongoing ketosis in children with a mild infective disease than ketones detection in the urine. These advantages are mitigated by the cost of 3HB measurement.

Disturbed eating behavior in pre-teen and teenage girls and boys with type 1 diabetes.

AIM: To investigate Disturbed Eating Behavior (DEB) and eating patterns in the context of a teenage population with T1D. METHODS: DEB was investigated using Eating Disorder Examination (EDE) test by a psychologist. Questions regarding insulin dosage manipulation or omission to obtain decrease in weight were added. Specific behavioral items from the EDE were used to define DEB: Objective Binge-eating, Self-induced Vomiting for weight control; the use of Diuretics, Laxatives or Insulin Omission for weight loss. Some EDE items provided information about four composite subscales which assesse Restraint, Eating concern, Shape concern and Weight concern. RESULTS: Shape and Weight concern showed significantly higher scores than those observed in the other two subscales (p=0.021). Average scores of each subscale resulted significantly higher in girls than in boys as well as in teen than in pre-teen participants. Objective binge eating (20%) and insulin dosage omission or reduction (17.6%) were the most common DEB (p<0.03). Forty-one percent of participants reported to consume three, 25% four and 34% five meals daily. A significantly lower proportion of females than males resulted to consume breakfast and mid-afternoon snacks. CONCLUSIONS: Findings from this study suggest that caregivers working in pediatric diabetes units should be alert in order to discover some DEB such as medication omission and binge-eating, all indicative symptoms of dissatisfaction of the body and psychological distress in diabetes management.

Could infantile interactive drawing technique be useful to promote the communication between children with Type-1 diabetes and pediatric team?

AIM: to finding what young patients with type-1 diabetes (T1D) knows about their body and also on their illness in perspective to tailor educational interventions to their real ability to understand. METHODS: the present study involved 68 children with T1D , 5 to 14 years old with a duration of diabetes ranging from 2 to 6 years and a total HbA1c mean value of 7.96±0.87%. The sample was divided into two age Groups: 28 children 5 to 10 years old were gathered in the Group 1 and 40 teenagers aged from 11 to 14 years in the Group 2. These patients were invited to draw over a white paper using a black pencil "The human body as it is made inside". Subsequently they were asked to explain: "what is diabetes?" and "where does insulin go?". According to the methodology of the "interactive drawing", the interviewer interacted with the children while drawing, forcing them to verbalize the reasons for their choices, to justify their proceeding, to explain their plan and then to explicit their theories. Drawings and replies were classified as Correct, Correct-but-Incomplete and Incorrect. RESULTS: the overall production of correct/correct-but-incomplete drawings was 83.82% vs 16.20% of the incorrect ones. One-hundred of the children who have produced a correct drawing supplied also a correct verbal reply, whereas 100% of the children who have produced an incorrect drawing was unable to supply any information on diabetes or about insulin. Both younger and older subjects who produced a complete-but-incorrect drawing appeared to have misunderstood the action of insulin therapy (only 23% and 17% of correct replies). Children who produced incomplete drawings and provided incorrect replies to the questions about their disease showed also a HbA1c mean value higher (8.36±0.97%) compared to the children who drew and answered correctly (p=0.0023). CONCLUSIONS: the operative epistemic approach could represent a promising tool for a health professional team to verify the real understanding acquired by a child about T1D, and to provide pediatrician a guideline to directly communicate with his patient.

Diabetic ketoacidosis at the onset of Type 1 diabetes in young children Is it time to launch a tailored campaign for DKA prevention in children <5 years?

AIM: To analyze clinical characteristics associated with the occurrence of diabetic ketoacidosis (DKA) at the onset of type 1 diabetes (T1D) in children aged <5 years in order to identify early signs or symptoms useful to prevent DKA appearance. METHODS: Data of patients  with newly diagnosed TID aged <5 years (Group 1) and 6-10 years old  (Group 2) coming from the province of Parma were collected in the period 2012-2016. RESULTS: Mild/moderate ketoacidosis at diabetes diagnosis occurred more frequently in Group 1 than in Group 2 patients (p<0.0015). Severe DKA incidence was higher in children below 5 (21.8%) than in those over 5 years of age (3.75%; p=0.021). Latent period before overt T1D diagnosis was longer in Group 1 than in Group 2 patients (p=0.0081). During this latent period similar indicators were recorded among parents of children <3 years old: frequent use of disposable baby diapers (87%), wet baby diapers because of a large amount of urine (86%), body weight loss (79%).  In children aged 3-4 years reported symptoms consisted of polyuria (89%), polydipsia (79%), fatigue (72%). In Group 2 patients predominant signs concern unusual episodes of  enuresis. CONCLUSIONS: We believe that it is time to launch a DKA prevention campaign tailored for children under 5 years old and focused just on the above-mentioned three warning signs. Information program must involves pediatricians, pediatric nurses, new moms and nursery school teachers.

Effectiveness of a tailored medical support to overcome the barriers to education, treatment and good metabolic control in children with type-1 diabetes from ethnic minorities.

AIM: To analyze the effectiveness of a tailored medical support to help children from ethnic minorities to achieve the same good metabolic control of autochthonous peers with type-1 diabetes (T1D). METHODS: Children <10 years of age belonging to ethnic minority (EM) families (Group 1) were compared with autochthonous peers (Group 2) who received the diagnosis of T1D in 2014-2016. The Protocol for minorities included other than the standard protocol: booklets translated in ethnic minority languages; weekly visits at home or at school; family-guides; clinic visits supported by professional interpreters. After twelve months of this approach, parents of ethnic minority children answered a short questionnaire concerning satisfaction about educational tools for diabetes management. RESULTS: From 1st January 2014 to December 31st 2016, 72 children received the diagnosis of T1D at the University Children Hospital of Parma, Italy. Nineteen children belonged to an EM family (26.38%), and were included in the Group 1. Twenty-one autochthonous peers were randomly recruited for the Group 2. T1D was diagnosed at the same mean age in Group 1 (5.2±2.2) and in Group 2 patients (5.7±2.4). Metabolic derangements at diagnosis were more severe in Group 1 than in Group 2 patients. However, patients of both Groups showed a similar decrease in HbA1c levels during the first 3 and 6 months post diagnosis. Patients did not differ in mean insulin doses at discharge and at follow up. The calls to the emergency toll-free telephone number were more numerous from the parents from Group 1 than from the parents of Group 2. Total cost to implement the tailored protocol in Group 1 was higher of 87% compared with the standard protocol used for Group 2 patients. Great majority of parents reported to be satisfied with the provided diabetes education program. CONCLUSIONS: The results of this study suggested that children from EM families can achieve the same good metabolic control of autochthonous peers with T1D, providing a cost-effective tailored support to their family members.

Spontaneous Dissemination in Neighboring Provinces of DKA Prevention Campaign Successfully Launched in Nineties in Parma's Province.

AIM: to investigate how much effectiveness of the historical campaign of DKA prevention at T1D diagnosis has survived in Parma's province where this was launched in Nineties, and how much it has spontaneously spread in the neighboring provinces. METHOD: children aged 6-14 years with newly diagnosed TID coming from province of Parma (Group 1) and from two other nearby provinces (Group 2)  were investigated. Clinical and laboratory data were retrospectively collected from medical files of each patient and included age, gender, capillary pH, serum bicarbonate, 3-beta-hydroxybutyrate (3HB), glycated hemoglobin (HbA1c) at the time of admittance from 1st January 2012 and 31 December 2016. RESULTS: no DKA condition was globally found in 25/36 patients (69.4%): 16/17  and 9/19 patients  belonged to Group 1 and 2 respectively (p=0.002). Mild or moderate DKA was reported in 5.9% patients of Group 1 and in 47.31%  (p=0.005) patients from Group 2. Severe DKA was observed in only 1 child from Group 2. Normal 3-beta-hydroxybutyrate (3HB) serum levels was reported in the 25 patients without DKA at diabetes diagnosis. Duration of hyperglycemia-related symptoms before overt T1D diagnosis was shorter (4.6±2.5 days) in patients with 3HB levels <1 mmol/dl  than in those with 3HB levels exceeding  1 mmol/dl (9.6±4.2 days, p< 0.0001). HbA1c values were on overage lower in patients without DKA (9.9±1.2%) than in patients with DKA at diabetes diagnosis (13.60±1.3%; p< 0,001). CONCLUSION: 1) the campaign for DKA prevention, launched  in Nineties and renewed at beginning of Twenties in Parma's province,  continues to be effective in the same province after several years; 2) in the two control provinces despite no information campaign being officially promoted in loco, an unexpected decrease in severe DKA incidence as well a shorter latency before overt T1D diagnosis were  observed in the same  period.

Long-acting insulin allergy in a diabetic child.

Insulin allergy has been uncommon since the introduction of human recombinant insulin preparations; the prevalence is 2.4%. Insulin injection could elicit immediate reactions, which are usually induced by an IgE-mediated mechanism, within the first hour after drug administration. In the present study, we describe the case of a child who experienced immediate urticaria after long-acting insulin injection. A 9-year-old girl affected by type I diabetes mellitus referred a history of three episodes of urticaria 30 min after insulin subcutaneous injection. During the first week of insulin therapy, she developed generalized immediate urticaria twice after long-acting insulin glargine first and then once after insulin degludec administration. Symptoms resolved within a few hours after treatment with oral antihistamine. She tolerated rapid insulin lispro. Her personal allergological history was negative. Skin prick tests with degludec, glargine and detemir were performed, showing negative results. Intradermal 1:100000-diluted tests were immediately positive for both degludec and glargine but not for detemir. In light of these findings, detemir was administered without any reaction. Our results show that detemir is tolerated by patients with clinical hypersensitivity reactions to degludec and glargine. Although reactions could be attributable to additives allergy, such as zinc or metacresol, this was excluded since all three preparations contain the same components. So, insulin itself acted as offending allergen. Detemir differs from degludec and glargine in a few aminoacids. Therefore, it is possible that the conformational rather than the linear epitope may be responsible for the reaction. This result suggests integrating intradermal tests in the diagnostic flowchart for insulin allergy. Insulin allergy should always be suspected in patients with immediate symptoms after drug injection. As allergologic work-up, prick by prick test and intradermal test to insulin preparations should be performed. In case of negative results of cutaneous tests, insulin analogs may be administered.

Children with type 1-diabetes from ethnic minorities: vulnerable patients needing a tailored medical support.

BACKGROUND AND AIM: Newly diagnosed children with type 1 diabetes from ethnic minorities are a growing presence in outpatient pediatric clinics, and are reported as a group at risk of poor metabolic control. In the present study we investigated the barriers affecting chances of minority diabetic children to achieve the same metabolic targets of native peers with type 1 diabetes. MATERIALS AND METHODS: The study investigated 35 children from ethnic minorities (group 1) admitted to the Children University Hospital of Parma, Italy, from 1st January 2000 to December 31st, 2011, and data concerning current age, gender, ethnicity, age at diabetes onset, HbA1c, DKA severity degree at diagnosis, insulin therapy, annual number of out patient clinic visits, number of admissions for acute decompensation, and treatment cost. A short questionnaire on background, family situation, difficulties in diabetes monitoring, and outpatient clinic procedures completed the study. The results were compared with data collected from 30 matched native peers (group 2). RESULTS: Mean HbA1c level at admittance was higher in Group 1 (11.8 +/- 1.0%) than in Group 2 (9.0 +/- 2.2%; p=0.000). The differences were confirmed when HbAlc mean cumulative values (8.6 +/- 2.1 vs 7.6 +/- 1.1; p=0.022) were calculated. Group 1 children at admission showed poorer metabolic conditions and longer stay at hospital (16 +/- 3 days) than Group 2 patients (8 +/- 2 days; p=0.000). The total costs for DKA treatment and family education resulted higher in group 1 (+54%) than in group 2 patients. Discontinuous capillary blood glucose monitoring and outpatient clinic visits missed were more frequent in Group 1 than in group 2 patients. Thirteen patients in group 1 needed a re-admittance to hospital because of a hypoglycemia (5 cases) or a hyperglycemia (8 cases). The same episodes were not recorded in group 2 patients. Most of parents expressed the wish to be supported with educational material in their own language. CONCLUSIONS: Children with TDM belonging to an ethnic minority had poorer metabolic control compared with native patients. This results from several cultural, educational, economic deficiencies which influence their family life and probably reduced their chances to obtain a better control.

Sulfonylurea-responsive neonatal diabetes mellitus diagnosed through molecular genetics in two children and in one adult after a long period of insulin treatment.

A permanent neonatal diabetes mellitus has finally been diagnosed through molecular genetics in two children and one adult after 9 to 35 years of uninterrupted insulin treatment. These patients developed diabetes before 6 months of age and were autoantibody negative. In one boy, a mutation in the KCNJ11 gene was identified at 9 years of age. In the other two patients (daughter and father, 12.6 and 25 years old respectively) the new gene variant (ABCC8/L213P) was found. Switching from insulin to sulfonylurea treatment leads to the definitive discontinuance of insulin therapy, improving metabolic control as well as the amelioration of the associated neurodevelopmental disabilities in the young girl in which an intermediate Development Delay, Epilepsy, Neonatal Diabetes syndrome was diagnosed.

Celiac disease in children with type 1 diabetes: impact of gluten free diet on diabetes management.

UNLABELLED: Background and aim of the work the coexistence of Type 1 Diabetes (T1D) and celiac disease (CD) has been long established. METHODS: Between January 2000 and December 2009, biopsy-proven CD was diagnosed in 12 children with T1D, giving a prevalence of 4.8 % in our out-patient clinic population. For each patient with coexisting T1D and CD, two control subjects with T1D and without CD who matched for age, sex and duration of diabetes were chosen. Prospective study follow up lasted 24 months. At the enrolment time, and at 2-month intervals, time from diagnosis of T1D to diagnosis of CD, presence of gastrointestinal symptoms, HbA1c value, body mass index (BMI), Height and Weight SDS were collected by a single observer. Daily insulin requirements were also retained. RESULTS: In 3 children, CD predated the onset of T1D and these children were excluded from the analysis. The 9 children who subsequently developed CD became earlier diabetic than control group (p=0.002). Eight of these children had CD diagnosis within 1 year after T1D onset. Seven out of 9 children were positive for TTG antibodies and all were positive for EMA. A significant increase in insulin requirement was found in CD children after 1 year of GFD (p= 0.02). The mean HbAlc value in CD children was higher than in the control subjects (p<0.01).A significant increase in the insulin requirement after 1 year in the GFD compliant children was found. There was a significant improvement in height-SDS after institution of GFD in the GFD-compliant children. Families of children with both T1D and CD reported higher burden than those affected by T1D only (p=0.001). The health care providers perceived family burden to increase with CD appearance (p<0.05). CONCLUSION: Our study supports the importance of screening for CD in children with T1D 1. The early treatment with GFD of biopsy-confirmed CD children promotes a significant catch-up growth and prevents a growth failure during the follow-up.

Haemolysis during diabetic ketoacidosis treatment in two girls with incomplete glucose-6-phosphate dehydrogenase deficiency.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a typical X-linked enzymopathy causing severe haemolytic anaemia in males, and mild to moderate anaemia in homozygous females. Haemolysis due to G6PD deficiency in patients with type 1 diabetes mellitus (T1DM) has been principally reported in males, but is uncommon. During the last 10 years 2 girls with an unknown incomplete G-6-PD deficiency showed haemolysis during the treatment of DKA at the onset of T1DM. We speculate that the patients here described showed haemolytic anaemia as a phenotypic expression of the lyonization process and/or an uncommon penetrance of the defective gene. Haemolysis occurred when blood glucose levels were returning to normal values. In normal red blood cells, G6PD provides a source of reducing power for maintaining sulphydryl groups (SH) and facilitating the detoxification of free radicals and peroxides. During insulin i.v. infusion the copious glucose available due to the hyperglycaemia progressively decreased and affected the old red blood cells to generate nicotinamide adenine dinucleotide (NADPH), a crucial source for energy-dependent functions. This NADPH loss could have enhanced the rate of all factors such as methaemoglobin generation, Heinz body formation, and lipid peroxidation, which occur in G6PD deficient cells in response to both endogenous and exogenous oxidants. The direct consequence of this phenomenon is an increased erytrocyte oxidant sensitivity and a loss of sulphydryl group availability causing premature red blood cell destruction.
