RESUMO
BACKGROUND: The Prevalence of liver disease among diabetics has been estimated to be between 17% and 100%. Most of these data were obtained from adult studies. The aim of our study was to screen for liver disease among type 1 diabetic children. METHODS: Children with type 1 diabetes following in clinic have been examined for existence of liver disease, from November 2008 to November 2009. All were subjected to the following: History, physical examination, liver function tests, fasting lipid profile, HbA1C, and ultrasound of the liver. A hyperechogenic liver and/or hepatomegaly on ultrasound were attributed most likely to excess glycogen or fat in the liver, after negative extensive work-up to rule out other underlying liver disease. RESULTS: 106 children with type 1 diabetes were studied: age ranged between 8 months to 15.5 years, sixty two patients were females. Twenty two patients (21%) were identified to have abnormal findings on ultrasound of the liver: 10 patients had hepatomegaly and 12 had hyperechogenic liver. The group with hyperechogenic liver had poorer glycemic control than patients with normal liver (Mean HbA1c 12.14% Vs 10.7%; P value = 0.09). Hyperechogenic liver resolved in 60% at 6 months follow-up upon achieving better glycemic control. CONCLUSIONS: Hyperechogenic liver and/or hepatomegaly are not uncommon in children with type 1 diabetes and tend to be more prevalent among children with poor glycemic control. Type 1 diabetes related hepatopathy is reversible by optimizing glycemic control. Because of its safety, and reliability, ultrasound can be used to screen for hepatopathy in type 1 diabetic child.

BACKGROUND AND AIMS: A number of studies in adults have evaluated the prevalence of gallstones in the diabetic population and showed a significant association with type 1 diabetes (T1D) and type 2 diabetes. The pediatric literature is limited to a single small case series. We conducted a cross-sectional study to evaluate for the presence of association between T1D in children and gallstones formation. PATIENTS AND METHODS: Children diagnosed with T1D in a diabetic clinic have been examined for existence of gall bladder stone formation from November 2008 through November 2009. All have been subjected to the following: History, physical examination, blood tests (liver function tests, lipid profile, glycosylated hemoglobin [HbA1C]), and an ultrasound (US) of the gall bladder. RESULTS: One hundred and five children with T1D have been enrolled consecutively over a 1-year period: age ranged between 8 months and 15.5 years, 62 patients were females. The mean age at diagnosis was 6.3 ± 2.9 years (range 0.85-11 years), mean duration of T1D was 2.2 ± 2.1 years (range 0.2-8 years), mean body mass index was 16.5 ± 3.4, mean HbA1c was 10.7 ± 2.4%, and 61.3% of patients had a HbA1c level >10%. The mean serum cholesterol was 4.16 ± 0.75 mmol/L (normal 3.65-5.15 mmol/L) and mean serum triglyceride 1.02 ± 1.3 mmol/L (normal 0-1.7 mmol/L). Two patients had hyperlipidemia. US of the gallbladder did not show any case of gallstones or sludge formation. CONCLUSION: Data from our study do not show any association between T1D in children and gallstones formation, with diabetes duration of less than 8 years. The relatively short duration of diabetes and possibility that our study was underpowered might have been reasons for the absence of any association.
