An 11-year-old boy with Klinefelter syndrome had Castleman disease (CD) of plasma cell type develop. Nonregulated antibody production mimicked systemic lupus erythematosus (SLE). Hepatitis C virus (HCV) infection caused significant disease worsening. The patient was treated with a daily dosage of 2 million units/m2 of IFN-alpha. Dramatic clinical(More)
OBJECTIVE To determine whether the progression of urinary albumin excretion rate (AER) is higher during puberty than before or after this period. RESEARCH DESIGN AND METHODS A prospective study was conducted in which normoalbuminuric prepubertal (n = 20), pubertal (n = 28), and postpubertal (n = 26) IDDM groups matched for diabetes duration and long-term(More)
The case of an 11 year old girl with three line type of polycythaemia vera, with 4 cm splenomegaly and a plethoric complexion is presented. Peripheral blood values were as follows: RBC: 7.75 x 10(12)/l, Hb: 18.8 g/l, WBC: 15.2 x 10(9)/l, platelets: 920 x 10(9)/l. Serum erythropoietin level: < 1 mU/ml. In vitro, erythroid colonies developed from the bone(More)
The aim of the present study was to investigate peripheral sensory nerve function in diabetic children and adolescents without neurological symptoms. Ninety-two children and adolescents with Type 1 (insulin-dependent) diabetes mellitus (mean +/- SD age: 14.2 +/- 2.1 years, diabetes duration: 5.8 +/- 3.0 years) and 80 healthy control subjects (age: 13.8 +/-(More)
The aims of the present study were to investigate the relationship between severe hypoglycaemia and autonomic dysfunction in diabetic children, and to assess the glycaemic response to an insulin infusion test. In a one year period, 12 of 69 diabetic patients (17%) experienced at least one severe episode of hypoglycaemia, defined as an event which required(More)
The aim of the present study was to evaluate the influence of autonomic nervous system dysfunction on work capacity in children and adolescents with Type 1 (insulin-dependent) diabetes. Fifteen patients with autonomic dysfunction (abnormal autonomic tests, age: 14.9 +/- 2.3 years), 35 patients without autonomic dysfunction (normal autonomic tests, age: 15.2(More)
To establish whether impaired hypoglycaemic awareness is associated with increased rate of severe hypoglycaemia and to assess clinical predictors of severe episodes without warning symptoms a prospective study of 130 insulin-dependent diabetic children and adolescents was undertaken for 1 year. Using a structured questionnaire, 48 patients reported impaired(More)
AIMS To assess the distribution of the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene in children and adolescents with Type 1 diabetes and to evaluate the association between ACE genotype and blood pressure (BP). METHODS ACE genotypes were assessed in 124 normoalbuminuric, clinically normotensive Type 1 diabetic(More)
It has been suggested previously that a decrease in urinary dopamine output might be related to a decrease in the urinary sodium excretion in subjects with diabetic nephropathy suffering from type 2 diabetes. To investigate the renal dopamine status in children with type 1 (insulin-dependent) diabetes mellitus, we measured the 24-hour urinary excretion of(More)
The genetically determined acetylator phenotype in diabetic children with and without increased urinary albumin excretion was investigated. Acetylator phenotype was determined according to Evans, and 24-hour albumin excretion rate (AER) was measured by immunoturbidometry in 86 children and adolescents with type 1 (insulin-dependent) diabetes mellitus and in(More)
