Celiac disease in children and adolescents with type I diabetes: importance of hypoglycemia.

BACKGROUND: Symptomatic hypoglycemia is an unavoidable problem in the treatment of type I diabetes. Celiac disease is associated with malabsorption and may therefore represent an important risk factor. METHODS: The frequency of symptomatic hypoglycemia in patients with type I diabetes and celiac disease (cases) was compared with those of patients who had diabetes without celiac disease (controls). For this purpose, each case was matched for age, sex, and duration of disease with one to two control patients. Indices of metabolic control (hemoglobin [Hb]A1c, frequency of hypoglycemia, and total insulin requirement) were retrieved for the 18 months before and after diagnosis of celiac disease. RESULTS: Eighteen patients (6 males and 12 females) had diagnosed celiac disease and were matched with 26 control patients (10 males and 16 females). There was no difference in age (11.0 years; range, 1.8-21.9 vs. 13.1 years; range, 2.3-22; P = 0.3) and duration of disease (8.4 years; range, 1.2-19.3 vs. 8.3 years; range, 1.1-18.7; P = 0.3) between the two groups. During the 6 months before and after diagnosis of celiac disease the cases had significantly more hypoglycemic episodes than the controls (means +/- SD; 4.5+/-4 vs. 2.0+/-2.2 episodes/months, P = 0.01). This was reflected by a progressive reduction in insulin requirement over the 12 months before diagnosis reaching a nadir at time 0 (0.6+/-0.2 vs. 0.9+/-0.3, P = 0.05). CONCLUSION: These data suggest that underlying celiac disease is associated with an increased risk of symptomatic hypoglycemia and that the introduction of a gluten-free diet with normalization of the intestinal mucosa may reduce its frequency.

Elevated circulating levels of monocyte chemoattractant protein-1 in patients with restenosis after coronary angioplasty.

Inflammation plays a pathogenic role in the development of restenosis after percutaneous transluminal coronary angioplasty (PTCA). Monocyte chemoattractant protein-1 (MCP-1) is a potent chemoattractant of monocytes; however, its role in the pathophysiology of restenosis is still unclear. We set out to investigate the role of MCP-1 in restenosis after PTCA. In addition, we tested the hypothesis that MCP-1 exerts its effect, at least in part, by inducing O(2)(-) generation in circulating monocytes. Plasma levels of MCP-1 were measured before and 1, 5, 15, and 180 days after PTCA in 50 patients (30 males and 20 females, aged 62+/-5 years) who underwent PTCA and who had repeated angiograms at 6-month follow-up. Restenosis occurred in 14 (28%) patients. The MCP-1 level was no different at baseline between patients with or without restenosis. However, after the procedure, restenotic patients, compared with nonrestenotic patients, had statistically significant (P<0.0001) elevated levels of MCP-1. In contrast, plasma levels of other chemokines, such as RANTES and interleukin-8, did not differ between the 2 groups after PTCA. Higher MCP-1 throughout the study was correlated with restenosis. Moreover, increased MCP-1 was significantly correlated with increased monocyte activity, as reflected by enhanced O(2)(-) generation. Finally, multivariate regression analysis showed that the MCP-1 plasma level measured 15 days after PTCA was the only statistically significant independent predictor of restenosis (beta=0.688, P<0.0001). This study suggests that MCP-1 production and macrophage accumulation in the balloon-injured vessel may play a pivotal role in restenosis after PTCA. MCP-1 may induce luminal renarrowing, at least in part, by inducing O(2)(-) release in monocytes. Further understanding of the mechanism(s) by which MCP-1 is produced and acts after arterial injury may provide insight into therapies to limit the progression of atherosclerosis and restenosis after balloon angioplasty.

New trends in the etiopathogenesis of diabetic peripheral neuropathy.

Neuropathy is well recognized as a major complication of insulin-dependent diabetes mellitus in adults, resulting in significant morbidity and possibly an increased mortality. Both the peripheral and autonomic nervous systems can be involved, and adolescents with diabetes can show early evidence of neuropathy. The pathogenesis of diabetic neuropathy remains unclear but is thought to involve various mechanisms. This complication can be traced to the metabolic effects of hyperglycemia and/or other effects of insulin deficiency on the various constituents of the peripheral nerve. The polyol pathway and/or nonenzymatic glycation affecting one or more cell types in the multicellular constituents of the peripheral nerve appear likely to have an inciting role. The role of other factors, such as possible direct neurotrophic effects of insulin and insulin-related growth factors, seems to be relevant.

Increased vascular endothelial growth factor serum concentrations may help to identify patients with onset of type 1 diabetes during childhood at risk for developing persistent microalbuminuria.

This study was designed to evaluate whether vascular endothelial growth factor serum concentrations may identify adolescents with onset of type 1 diabetes during childhood at greater risk to develop persistent microalbuminuria and incipient diabetic nephropathy. In January 1989, vascular endothelial growth factor serum levels were measured in 101 normoalbuminuric diabetic children and adolescents (aged 7-14.9 yr; onset of diabetes before age 18 yr; duration of diabetes >7 yr). Participants were clinically examined at baseline and annually thereafter. Vascular endothelial growth factor serum concentrations were measured every year during the 8-yr follow-up period. Over 8 yr, 11 of 101 patients (10.9%) developed persistent microalbuminuria; no patient developed overt nephropathy. The risk of developing microalbuminuria was higher in children with increased vascular endothelial growth factor serum levels (using 160 pg/ml as the arbitrary cut-off point; group 1) compared with those with normal vascular endothelial growth factor serum levels at the beginning of the study (group 2; 19.2 vs. 2.0%; P < 0.01; sensitivity, 90.9%; specificity, 53.3%). The odds ratio for the occurrence of microalbuminuria after adjustment for confounding variables (albumin excretion rate, sex, hemoglobin A(1c), mean blood pressure, cholesterol, and triglycerides) in type 1 diabetic adolescents with elevated vascular endothelial growth factor serum levels was 4.1 (95% confidence interval, 2.0-10.9). These results suggest that vascular endothelial growth factor serum concentrations may be one of the predictors and risk factors for microalbuminuria and incipient diabetic nephropathy in adolescents and young adults with onset of diabetes during childhood. Persistently increased vascular endothelial growth factor serum levels may help to identify normotensive, normoalbuminuric patients with type 1 diabetes who are predisposed to develop persistent microalbuminuria later in life.

Idiopathic short stature.

Idiopathic short stature (ISS) is a term used to describe the status of children with short stature that cannot be attributed to a specific cause. Many children diagnosed as having ISS have partial GH insensitivity, which can result from disturbances at various points of the GH-IGF-I axis. Several clinical studies on spontaneous growth in ISS showed that adult height was almost in the range of target height. GH treatment led to adult height not significantly higher than the pretreatment predicted adult height in most reports. No metabolic side effects have been observed, even when the dose was higher than in GH deficiency. Manipulation of puberty with gonadotrophin releasing hormone analogues reported by a few authors in a small number of children has shown conflicting results. Long-term psychological benefits of GH therapy for short normal children have not been demonstrated to date.

Isolated growth hormone deficiency in children and adolescents.

Although it is difficult to reach international agreement on the definition of growth hormone deficiency (GHD) in children and adolescents, great efforts to do so have been made during the last two decades. A somewhat limited definition of GHD is: a combination of auxological, clinical, biochemical and metabolic abnormalities caused by lack or insufficiency of GH secretion that results in a decrease in the production of GH-dependent hormones and growth factors. Its aetiology is very complex. Therefore, specific studies must be performed during different periods of childhood (neonatal, prepubertal and pubertal periods). Auxological parameters, particularly growth velocity (GV), are still considered the best clinical measures for analysing human growth. The spectacular advances in our understanding of molecular biology during the past twenty years have allowed, and will continue to allow, a more and more precise diagnosis of the molecular anomalies of human growth. This will, in turn, allow changes caused by genetic lesions to be more efficiently distinguished from those due to nutritional, organic, tumoural, psychological or traumatic causes. Our knowledge of the molecular bases of undergrowth due to a deficiency in GH has developed as a result of the localisation and characterisation of human genes which code for proteins implicated in the hormonal regulation of growth. These genes include pituitary GH (GH1), pituitary transcription factor 1 (Pit-1), the prophet of Pit-1 (PROP-1), the pituitary transcription factor LHX3, the transcription factor HESX1 and the GH-releasing hormone receptor (GHRHr). In addition, magnetic resonance imaging is the best available imaging method for the evaluation of size and structure of the pituitary and the parasellar region.

Good metabolic control is associated with better quality of life in 2,101 adolescents with type 1 diabetes.

OBJECTIVE: It is unclear whether the demands of good metabolic control or the consequences of poor control have a greater influence on quality of life (QOL) for adolescents with diabetes. This study aimed to assess these relations in a large international cohort of adolescents with diabetes and their families. RESEARCH DESIGN AND METHODS: The study involved 2,101 adolescents, aged 10-18 years, from 21 centers in 17 countries in Europe, Japan, and North America. Clinical and demographic data were collected from March through August 1998. HbA(1c) was analyzed centrally (normal range 4.4-6.3%; mean 5.4%). Adolescent QOL was assessed by a previously developed Diabetes Quality of Life (DQOL) questionnaire for adolescents, measuring the impact of diabetes, worries about diabetes, satisfaction with life, and health perception. Parents and health professionals assessed family burden using newly constructed questionnaires. RESULTS: Mean HbA(1c) was 8.7% (range 4.8-17.4). Lower HbA(1c) was associated with lower impact (P < 0.0001), fewer worries (P < 0.05), greater satisfaction (P < 0.0001), and better health perception (P < 0.0001) for adolescents. Girls showed increased worries (P < 0.01), less satisfaction, and poorer health perception (P < 0.01) earlier than boys. Parent and health professional perceptions of burden decreased with age of adolescent (P < 0.0001). Patients from ethnic minorities had poorer scores for impact (P < 0.0001), worries (P < 0.05), and health perception (P < 0.01). There was no correlation between adolescent and parent or between adolescent and professional scores. CONCLUSIONS: In a multiple regression model, lower HbA(1c) was significantly associated with better adolescent-rated QOL on all four subscales and with lower perceived family burden as assessed by parents and health professionals.

Persistent differences among centers over 3 years in glycemic control and hypoglycemia in a study of 3,805 children and adolescents with type 1 diabetes from the Hvidøre Study Group.

OBJECTIVE: Twenty-one international pediatric diabetes centers from 17 countries investigated the effect of simple feedback about the grand mean HbA(1c) level of all centers and the average value of each center on changes in metabolic control, rate of severe hypoglycemia, and insulin therapy over a 3-year period. RESEARCH DESIGN AND METHODS: Clinical data collection and determination of HbA(1c) levels were conducted at a central location in 1995 (n = 2,780, age 0-18 years) and 1998 (n = 2,101, age 11-18 years). RESULTS: Striking differences in average HbA(1c) concentrations were found among centers; these differences remained after adjustment for the significant confounders of sex, age, and diabetes duration. They were apparent even in patients with short diabetes duration and remained stable 3 years later (mean adjusted HbA(1c) level: 8.62 +/- 0.03 vs. 8.67 +/- 0.04 [1995 vs. 1998, respectively]). Three centers had improved significantly, four centers had deteriorated significantly in their overall adjusted HbA(1c) levels, and 14 centers had not changed in glycemic control. During the observation period, there were increases in the adjusted insulin dose by 0.076 U/kg, the adjusted number of injections by 0.23 injections per day, and the adjusted BMI by 0.95 kg/m(2). The 1995 versus 1998 difference in glycemic control for the seven centers could not be explained by prevailing insulin regimens or rates of hypoglycemia. CONCLUSIONS: This study reveals significant outcome differences among large international pediatric diabetes centers. Feedback and comparison of HbA(1c) levels led to an intensification of insulin therapy in most centers, but improved glycemic control in only a few.

Endothelial perturbation in children and adolescents with type 1 diabetes: association with markers of the inflammatory reaction.

OBJECTIVE: The progression of diabetic angiopathy is, in most cases, unpredictable. The aim of this study was to investigate early events that could influence the development of diabetic angiopathy. RESEARCH DESIGN AND METHODS: Circulating levels of von Willebrand factor (vWF) and tissue-plasminogen activator (tPA), defining endothelial perturbation, were measured in 40 young patients with type 1 diabetes. Patients were divided into two groups according to the duration of diabetes (group A, <1 year; group B, >1 year) and compared with a control group of age- and sex-matched healthy individuals. Prothrombin fragment 1 and 2 (F(1+2)), tumor necrosis factor-alpha (TNF-alpha), and C-reactive protein (CRP) levels were also determined as markers of a prothrombotic state and inflammatory response. A total of 16 of the 20 children in group A were re-examined after 12 months. RESULTS: Compared with either normal subjects or patients in group B, children in group A showed increased levels of vWF, tPA, F(1+2), TNF-alpha, and CRP. Significant direct correlations between TNF-alpha or CRP and either vWF, tPA, or F(1+2) were observed. Endothelial perturbation was shown in 70% of group A and 20% of group B. After 1 year, 16 of the 20 patients in group A showed a significant reduction in vWF, tPA, F(1+2), TNF-alpha, and CRP levels, whereas endothelial perturbation was reversed in 5 of these patients. CONCLUSIONS: Endothelial perturbation represents an early and, in some cases, reversible event in the chronology of type 1 diabetes in children. A correlation might exist between the initial inflammatory reaction and the appearance of endothelial perturbation.

Serum leptin changes during weight loss in obese diabetic subjects with and without microalbuminuria.

To evaluate the changes of serum leptin levels after weight reduction in diabetic subjects with and without microalbuminuria, we studied 10 obese healthy subjects, 12 obese diabetics with persistent microalbuminuria and 10 obese diabetic subjects without microalbuminuria. Obese diabetic patients with microalbuminuria showed serum leptin levels significantly higher than normoalbuminuric diabetics, while no difference was found between obese diabetics without microalbuminuria and healthy controls. All obese subjects followed a 12-month intensive weight reduction program during which the mean change in body mass index was similar between obese diabetic and obese healthy subjects (obese diabetics without microalbuminuria: 35.2+/-4.3 vs 29.9+/-4.1, p<0.05; obese diabetics with microalbuminuria: 35.7+/-3.9 vs 30.3+/-4.0, p<0.05; obese healthy subjects: 35.5+/-4.0 vs 30.1+/-3.9, p<0.05). The mean changes in serum leptin levels tended to be similar in two groups of subjects studied (obese diabetics without microalbuminuria: 37.6+/-4.1 vs 19.7+/-4.9, p<0.001; obese healthy subjects: 37.1+/-4.3 vs 20.1+/-5.1, p<0.001); obese microalbuminuric subjects showed higher leptin levels (42.4+/-4.0 vs 30.3+/-4.2, p<0.001) than normoalbuminuric diabetic and obese healthy subjects. In conclusion, during weight loss, independently from the quality of metabolic control, serum leptin concentrations declined in both groups of obese diabetics. The changes of leptin in diabetics seem to be similar to those observed in healthy obese subjects.

The potential role of insulin analogues in the treatment of children and adolescents with Type 1 diabetes mellitus.

The main therapeutic challenge in the treatment of Type 1 diabetes is maintenance of near-normoglycaemia in order to prevent long-term complications and avoid hypoglycaemia. This goal is relevant from the onset of the disease and is feasible if physiological models of insulin replacement are used and patients are educated in the strategy of intensive insulin therapy. Although the use of available insulins within a multiple injection regimen has improved, metabolic control it is still far from being optimal. The recent introduction of insulin analogues with a short- and long-acting profile seems promising in improving metabolic control and quality of care. Insulin lispro and insulin aspart, the short-acting insulin analogues offer a better post-prandial profile, while insulin glargine the new long-acting insulin analogue might provide better overnight control. In fact, the theoretical combination of an acute prandial insulin peak with a flat interprandial and overnight plasma profile would closely mimic the 24-hr insulin profile of non-diabetic individuals. This would possibly lead to lower post-prandial blood glucose excursion and better fasting blood glucose associated with minimal risk of hypoglycaemia. The possible reduction of hypoglycaemia is especially important in children as recurrent episodes might represent a potential risk for cognitive impairment. However, recent clinical research on the short-acting insulin analogues demonstrates the difficulties of translating these theoretical benefits into clinical relevant advantages. This might happen to other insulin analogues and requires further and larger studies in order to fully exploit the theoretical advantages of insulin analogues in the paediatric population. Safety issues should also be carefully monitored when introducting analogues in long-term therapy.

Discontinuation of anticonvulsant therapy in children with partial epilepsy.

To evaluate when it is possible to discontinue anticonvulsant treatment in children with cryptogenic partial epilepsy, the authors studied 89 epileptic children divided into two groups: Group A, 45 children whose therapy was discontinued after 1 year from the last seizure; and Group B, 44 children whose therapy was stopped after 2 years from the last seizure. After 5 years of follow-up, the recurrence rate was similar in the two groups of patients (Group A, 28.8%; Group B, 25%). It is safe to discontinue the anticonvulsant therapy in children with cryptogenic partial epilepsy who were seizure free for only 1 year.

Antiproliferative effects of insulin-like growth factor-binding protein-3 in mesenchymal chondrogenic cell line RCJ3.1C5.18. relationship to differentiation stage.

Chondrogenesis results from a complex equilibrium between chondrocyte proliferation and differentiation. Insulin-like growth factors (IGFs) have a crucial role in chondrogenesis, but their mechanisms of action are not well defined. IGF-binding protein-3 (IGFBP-3) is the major carrier for circulating IGFs in postnatal life, and has been shown to have IGF-independent effects on proliferation of several cancer cell lines. In this study, we have evaluated the IGF-independent and -dependent effects of IGFBP-3 on chondrocyte proliferation and the relationship of these effects with chondrocyte differentiation stage. We used the RCJ3.1C5.18 nontransformed mesenchymal chondrogenic cell line, which, over 2 weeks of culture, progresses through the differentiation pathway exhibited by chondrocytes in the growth plate. We demonstrated that IGFBP-3 inhibited, in a dose-dependent manner (1-30 nm), the proliferation of chondroprogenitors and early differentiated chondrocytes, stimulated by des-(1-3)-IGF-I and longR(3)-IGF-I (IGF-I analogs with reduced affinity for IGFBP-3), and by insulin and IGF-I. In terminally differentiated chondrocytes, IGFBP-3 retained the ability to inhibit cell proliferation stimulated by IGF-I, but had no effect on cell growth stimulated by insulin, or des-(1-3)-IGF-I or longR(3)IGF-I. By monolayer affinity cross-linking, we demonstrated a specific IGFBP-3-associated cell-membrane protein of approximately 20 kDa. We determined that IGFBP-3 has an antiproliferative effect on chondrocytes and, that this effect is related to the differentiation process. In chondroprogenitors and early differentiated chondrocytes, antiproliferative effect of IGFBP-3 is mainly IGF-independent, whereas, following terminal differentiation this effect is IGF-dependent.

Lack of mother-to-child HIV-1 transmission is associated with elevated serum levels of 90 K immune modulatory protein.

BACKGROUND: 90 K is a secreted human serum glycoprotein with immune modulatory activity. METHODS: Serum 90 K levels were determined by an enzyme-linked immunosorbent assay in 19 HIV-1-infected mothers at the time of delivery, in their new-borns (11 HIV-1 infected and eight uninfected), in 26 HIV-1-uninfected mothers and in 86 new-borns of HIV-1-uninfected mothers. RESULTS: 90 K levels in HIV-1-infected transmissive mothers (22.4 +/- 13.9 microg/ml) were similar to those of HIV-1-uninfected mothers (21.1 +/- 7.6 microg/ml; P = 0.715), but lower than those of HIV-1-infected non-transmissive mothers (45.5 +/- 24.8 microg/ml; P = 0.019). The levels were higher in HIV-1-uninfected (47.6 +/- 22.4 mg/ml) than HIV-1-infected (23.7 +/- 15.6 microg/ml; P = 0.014) new-borns of HIV-1-infected mothers. The new-borns of HIV-1-uninfected mothers had lower levels (11.7 +/- 5.3 microg/ml) than both HIV-1-infected and HIV-1-uninfected new-borns of HIV-1-infected mothers (all differences, P < 0.001). CONCLUSION: These results suggest that high 90 K protein serum levels in HIV-1-infected mothers and their new-borns are associated with lack of mother-to-child HIV-1 transmission.

Interleukin-6 release by cultured peripheral blood mononuclear cells inversely correlates with height velocity, bone age, insulin-like growth factor-I, and insulin-like growth factor binding protein-3 serum levels in children with perinatal HIV-1 infection.

Spontaneous and phytohemagglutinin (PHA)-stimulated interleukin (IL)-6 release by cultured peripheral blood mononuclear cells was related to height velocity, bone age, insulin-like growth factor-I (IGF-I), and IGF binding protein-3 (IGFBP-3) serum level standard deviation scores (SDS) of 32 children [aged 91 (median; range 13-151) months] with human immunodeficiency virus-type 1 (HIV-1) perinatal infection and severe disease. Spontaneous and PHA-stimulated IL-6 release inversely correlated with height velocity, bone age, IGF-I, and IGFBP-3 SDS. Ten children with height velocity SDS </= -2, compared to 22 children with height velocity SDS > -2, showed higher spontaneous and PHA-stimulated IL-6 release and lower IGF-I and IGFBP-3 SDS (irrespective of CD4-positive T-lymphocyte counts, viral load, liver disease, or nutrition status). IL-6 overproduction may be a mechanism of IGF-I and IGFBP-3 down-regulation and impaired linear growth in children with perinatal HIV-1 infection. Growth-promoting strategies, including targeted anticytokine treatments, could be devised for such children.

Advanced glycation end products in adolescents and young adults with diabetic angiopathy.

The aim of this study was to evaluate serum advanced glycation end products (S-AGEs) in a group of adolescents and young adults with type 1 (insulin-dependent) diabetes mellitus and with diabetic microvascular complications (nephropathy or retinopathy). Fifty-two patients were included in the study (age range 14.2-28.8 years, onset of diabetes before the age of 12 years, duration of diabetes longer than 7 years); 45 patients without diabetic angiopathy and 63 healthy controls were also selected. S-AGEs were significantly increased in patients with diabetic angiopathy compared with controls (19.9+/-3.8 vs. 11.8+/-2.8 U/ml, P<0.001). Higher S-AGE levels were found in patients with severe diabetic nephropathy and retinopathy. When the albumin excretion rate (AER) was >100 microg/min per 1.73 m2, S-AGE levels were 23.1+/-2.4 U/ml; when the AER was 50-100 microg/min per 1.73 m2 levels were 19.8+/-1.9 U/ml, and for an AER of 20-50 microg/min per 1.73 m2 the corresponding value was 16.1+/-2.1 U/ml (P<0.005). Patients with proliferative retinopathy had S-AGE levels of 22.2+/-2.6 U/ml, those with preproliferative retinopathy 20.7+/-2.2 U/ml, and background retinopathy 17.6+/-1.9 U/ml (P<0.01). A significant correlation was found between levels of glycosylated hemoglobin (HbA1c) and S-AGE (r=0.43, P<0.01). S-AGE concentrations are markedly increased in type 1 diabetic adolescents and young adults with diabetic nephropathy and retinopathy. The severity of diabetic angiopathy is related to the serum levels of AGEs.

Stormy onset of benign childhood epilepsy with occipital paroxysmal discharges.

We studied six children with ages ranging from 4 to 10 years who were affected by childhood epilepsy with occipital paroxysms and presented after a stormy onset with prolonged loss of consciousness for 6-14 h. In all these patients, seizures were preceded by visual symptoms in the form of colored circular disks. A CT scan was performed immediately after the onset of symptoms and was normal in all patients. Routine laboratory and cerebrospinal fluid examinations were normal in all patients. The interictal EEG was characterized by continuous or subcontinuous occipital spike wave discharges, which disappeared after the patients' eyes opened. We carried out a 7-year follow-up of all these patients. Only two patients were treated with antiepileptic drugs. The therapy (phenobarbital, clobazam) in the two patients did not induce changes in the EEG pattern. The first did not suffer any further seizures. The second patient had two more seizures (at 8 and 18 months from the onset) with phosphenes, confusional state, and involuntary movements followed by loss of consciousness. Among the other four patients, who did not receive any treatment, only one had any other seizures. The stormy onset of the syndrome described in our six patients emphasizes the extreme variability in the presentation of this type of childhood epilepsy. Our follow-up confirms the good prognosis of this epilepsy even when it has a stormy onset.
