Decreasing prevalence of retinopathy in childhood-onset type 1 diabetes over the last decade: A comparison of two cohorts diagnosed 10 years apart.

Aim: To ascertain whether the prevalence of retinopathy has declined over the last 2 decades in individuals with childhood-onset type 1 diabetes and whether this might be explained by changes in lifetime HbA1c.

Materials And Methods: A multicentre, retrospective, observational study, comparing 128 subjects with diabetes onset in 2000-2003 assessed for retinopathy in 2016-2019, with a previous cohort of 115 individuals diagnosed in 1990-1993 and assessed for retinopathy in 2007-2009, was conducted. The two cohorts had both a similar diabetes duration and age at diagnosis.

Kidney transplant in patients with atypical hemolytic uremic syndrome in the anti-C5 era: single-center experience with tailored Eculizumab.

Rationale And Objective: Patients with atypical hemolytic uremic syndrome (aHUS) have long been considered ineligible for kidney transplantation (KTx) in several centers due to the high risk of disease recurrence, graft loss and life-threatening complications. The availability of Eculizumab (ECU) has now overcome this problem. However, the best approach towards timing, maintenance schedule, the possibility of discontinuation and patient monitoring has not yet been clearly established.

Whole lipid profile and not only HDL cholesterol is impaired in children with coexisting type 1 diabetes and untreated celiac disease.

Aims: Low HDL cholesterol (HDL-C) levels have been described in patients with coexisting type 1 diabetes mellitus (T1DM) and celiac disease (CD). Data on other possible lipid abnormalities that could further increase cardiovascular risk in these patients are scarce and incomplete. Aim of this retrospective multicenter study was to evaluate whole lipid profiles, besides HDL-C, in children with T1DM associated with biopsy-proven CD, and to investigate the influence of age and degree of adherence to gluten-free diet (GFD) on lipid changes.

Acquired Complement Regulatory Gene Mutations and Hematopoietic Stem Cell Transplant-Related Thrombotic Microangiopathy.

Hematopoietic stem cell transplant-related thrombotic microangiopathy (HSCT-TMA) is a severe complication whose pathophysiology is unknown. We describe 6 patients in which the disease was associated with complement regulatory gene abnormalities received from their respective donors. It is suggested that mutated and transplanted monocyte-derived cells are responsible for production of abnormal proteins, complement dysregulation, and, ultimately, for the disease.

Early Volume Expansion and Outcomes of Hemolytic Uremic Syndrome.

Background: Hemolytic uremic syndrome associated with Shiga toxin-producing Escherichia coli (STEC-HUS) is a severe acute illness without specific treatment except supportive care; fluid management is concentrated on preventing fluid overload for patients, who are often oligoanuric. Hemoconcentration at onset is associated with more severe disease, but the benefits of volume expansion after hemolytic uremic syndrome (HUS) onset have not been explored.

Methods: All the children with STEC-HUS referred to our center between 2012 and 2014 received intravenous infusion targeted at inducing an early volume expansion (+10% of working weight) to restore circulating volume and reduce ischemic or hypoxic tissue damage.

Ketoacidosis at diagnosis in childhood-onset diabetes and the risk of retinopathy 20years later.

Aims: To investigate on the relationship between severity of ketoacidosis, an important risk factor for C-peptide preservation, and long-term microvascular complications in childhood-onset type 1 diabetes mellitus (T1DM).

Methods: 230 childhood-onset diabetic patients (177 pre-pubertal), aged 7.0±3.

Hemoconcentration: a major risk factor for neurological involvement in hemolytic uremic syndrome.

Background: Shigatoxin-associated hemolytic uremic syndrome (STEC-HUS) is a common thrombotic microangiopathy (TMA) in which central nervous system (CNS) involvement is responsible for the majority of deaths and for severe long-term sequelae. We have analyzed the role of hemoconcentration in disease severity.

Methods: This was a retrospective review of the records and laboratory data at presentation of all patients with STEC-HUS cases (n = 61) over a 10-year period.

Complement functional tests for monitoring eculizumab treatment in patients with atypical hemolytic uremic syndrome.

Background: Atypical hemolytic uremic syndrome (aHUS) is a thrombotic microangiopathy characterized by hemolysis, platelet consumption, and renal injury. Eculizumab, a mAb that blocks complement activity, has been successfully used in aHUS.

Objectives: To optimize eculizumab therapy in aHUS patients by monitoring complement functional tests and markers of disease activity.

Transition from pediatric to adult care. eight years after the transition from pediatric to adult diabetes care: metabolic control, complications and associated diseases.

Background: Transition from pediatric to adult care is a critical process in the life of patients with diabetes.

Aim: Primary aim of the study was to compare the metabolic control between pediatric care and adult care at least 5 years in a group of patients with type 1 diabetes mellitus (T1DM). Secondary aim was to evaluate the presence of complications, associated diseases and psychological-psychiatric disorders.

Cryptic activity of atypical hemolytic uremic syndrome and eculizumab treatment.

Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening disease often related to uncontrolled complement activation. The use of eculizumab has changed the management and the outcome of aHUS, becoming the frontline treatment of the acute disease and for the prevention of relapses. We report the case of a male patient with aHUS due to complement factor H gene mutation who was shifted from plasmatherapy to eculizumab for preventing disease relapses.

Co-infection in children with bloody diarrhea caused by Shiga toxin-producing Escherichia coli: data of the North Italian HUS Network.

Hemolytic-uremic syndrome (HUS) is an important cause of acute kidney injury in children often caused by Shiga toxin-producing Escherichia coli (STEC) enterocolitis. In a screening program for STEC infection in children with bloody diarrhea in northern Italy for early diagnosis of HUS, co-infection with Salmonella or Campylobacter was documented in as many as 35.6% of Shiga toxin-positive patients.

Discontinuation of eculizumab maintenance treatment for atypical hemolytic uremic syndrome: a report of 10 cases.

Atypical hemolytic uremic syndrome (aHUS) is a life-threatening thrombotic microangiopathy, and as many as 70% of patients with aHUS have mutations in the genes encoding complement regulatory proteins. Eculizumab, a humanized recombinant monoclonal antibody targeting C5, has been used successfully in patients with aHUS since 2009. The standard maintenance treatment requires life-long eculizumab therapy, but the possibility of discontinuation has not yet been tested systematically.

Skin involvement in atypical hemolytic uremic syndrome.

Skin involvement in atypical hemolytic uremic syndrome (aHUS) is very uncommon and therefore often unrecognized as a specific symptom of aHUS. We describe 3 cases of patients with aHUS who developed skin lesions that completely recovered when disease-specific treatment was established. These cases suggest that in individuals with aHUS, when skin lesions of unknown origin occur, the possibility that they are due to thrombotic microangiopathy should be considered.

A controlled, class-based multicomponent intervention to promote healthy lifestyle and to reduce the burden of childhood obesity.

Background: Overweight and obesity prevention in childhood and adolescence represent a priority for public health; school is a privileged place for health promotion interventions.

Objectives: The study aimed to test the effectiveness of a multicomponent 5-month intervention on the habits of primary school children, making the families aware of the importance of healthy choices.

Methods: Two hundred nine children attending the fourth class of primary school, divided into interventional (n = 103) and control arm (n = 106) were included in the study.

Infant and toddler type 1 diabetes: complications after 20 years' duration.

Objective: To compare the effect of the prepubertal duration of diabetes on the occurrence of complications in two groups of patients after the same number of years of the disease.

Research Design And Methods: This multicenter study enrolled 105 patients aged 16-40.3 years; 53 were prepubertal at diagnosis (aged 0-3) and 52 were pubertal (Tanner stage) and aged 9-14.

Onset of type 1 diabetes mellitus in two patients with maturity onset diabetes of the young.

The association between maturity onset diabetes of the young (MODY) and type 1 diabetes mellitus (T1DM) has been rarely described. We report two patients affected by MODY who developed T1DM. Case 1: a 4-yr-old girl referred for glycosuria presented hemoglobin A1c (HbA1c) of 6.

High rate of regression from micro-macroalbuminuria to normoalbuminuria in children and adolescents with type 1 diabetes treated or not with enalapril: the influence of HDL cholesterol.

Objective: To evaluate the frequency of normalization, the persistence of remission, and the impact on normalization of glycemic control and lipid profile, we analyzed data from a retrospective observational cohort study of type 1 diabetic children and adolescents with abnormal urinary albumin excretion (UAE).

Research Design And Methods: All diabetic children and adolescents (n = 41) who had persistent abnormal UAE in the period of 1984 to 2008 and followed up until 2009 (follow-up duration = 13.1 ± 6.

Adducin- and ouabain-related gene variants predict the antihypertensive activity of rostafuroxin, part 1: experimental studies.

Essential hypertension is a complex, multifactorial disease associated with a high cardiovascular risk and whose genetic-molecular basis is heterogeneous and largely unknown. Although multiple antihypertensive therapies are available, the large individual variability in drug response results in only a modest reduction of the cardiovascular risk and unsatisfactory control of blood pressure in the hypertensive population as a whole. Two mechanisms, among others, are associated with essential hypertension and related organ damage: mutant α-adducin variants and high concentrations of endogenous ouabain.

Type 1 diabetes (T1DM) in children and adolescents of immigrated families in Emilia-Romagna (Italy).

Background And Aim Of The Work: The etiology and natural history of T1DM are still unknown but certainly both genetics and environmental factors contribute to the development of the disease. Migration studies are an important tool to better understand the role of the environment. The aim of this study was to investigate some variables in diabetic children of immigrant families living in Emilia-Romagna compared with Italian diabetic children living in the same region.
