Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes

Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening

Allergic contact dermatitis in children

Introduction: Allergic contact dermatitis is an inflammatory skin disease which accounts for up to 20% of all childhood dermatitis. Childhood allergic contact dermatitis is more frequent than previously thought and today early diagnosis is considered very important. Patch testing represents the gold standard method used to confirm the diagnosis of allergic contact dermatitis. The knowledge of the most common allergens involved in allergic contact dermatitis in pediatric age is important considering that the first-line management of allergic contact dermatitis in children is to avoid the involved allergens. Areas covered: We reviewed the literature on PubMed\uae and SciVerse Scopus\uae medical database about allergic contact dermatitis and emerging contact allergens in children. In this review, we summarize the clinical characteristics, differential diagnoses, and epidemiology of allergic contact dermatitis in children, underlying the most recent pieces of evidence about the most frequent and emerging contact allergens. Expert opinion: We believe that persistent, well localized and recurrent eczematous lesions in children should suggest an allergic contact dermatitis, inducing physicians to refer patients for patch testing. Physicians should be acquainted with the current trends and the emerging contact allergens in children, in order to provide not only the best treatment but also the best management and prevention

Mechanisms of acute and chronic hypoglycemic action of gliclazide.

An extrapancreatic effect of sulfonylureas has been postulated. However, in vivo results have been disputed because the amelioration of insulin action that follows sulfonylurea may represent the relief from glucose toxicity rather than a direct effect of the drug. Therefore, we studied the hypoglycemic action of gliclazide acutely and after 2 months of therapy in seven type 2 diabetic patients. All patients received a 240-minute IV glucose infusion with [3-H-3]glucose. In a random order, 160 mg gliclazide (study 1) or placebo (study 2) was given orally before glucose infusion. Finally, the effect of 160 mg gliclazide was reassessed after a two-month treatment with the same sulfonylurea (80 mg t.i.d.). Basal plasma glucose, insulin, C-peptide and endogenous glucose production (EGP) were similar before the two initial studies. During glucose infusion, EGP was more suppressed after gliclazide in spite of comparable increase in plasma insulin and C-peptide. After the two-month therapy, basal plasma glucose levels and HbA(1c) were lower while plasma insulin and C-peptide were higher with respect to baseline (p < 0.05). Gliclazide further reduced plasma glucose, the incremental area above baseline, and EGP during glucose infusion, while plasma insulin and C-peptide achieved higher plateaus (p < 0.05). When data were pooled, plasma glucose concentration and EGP correlated both in the basal state (r = 0.71) and during the last hour of glucose infusion (r = 0.84; both p < 0.05). These data suggest that gliclazide enhances the suppression of EGP induced by insulin and that this effect is greater with chronic treatment because of concomitant improvement of insulin secretion

Metabolic syndrome, non-alcoholic fatty liver disease and liver stiffness in psoriatic arthritis and psoriasis patients

OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD), potentially evolving into liver fibrosis (LF), is frequent in psoriasis (PsO), but data in psoriatic arthritis (PsA) are lacking. Our study aimed to investigate the prevalence of NALFD and LF in PsA/PsO and the contribution of arthritis in their onset. METHOD: PsA and PsO patients were consecutively enrolled. Exclusion criteria were liver diseases causing fibrosis (except NAFLD), alcohol 65\u200920 g/day, daily use of non-steroidal anti-inflammatory drugs and current/previous methotrexate use. Clinical history, biochemical and clinimetrical data and insulin-resistance index HOMA (homeostatic model assessment) were assessed. Patients underwent a liver ultrasound to identify steatosis (therefore NAFLD) and transient elastography, to evaluate LF (stiffness 65\u20097 kPa = fibrosis). Statistical analysis included basic statistics, logistic and linear regression analyses (to assess the contribution of arthritis to NAFLD and LF grading, respectively) and Spearman's correlations; p\u2009 64\u20090.05 was considered significant. RESULTS: Seventy-six patients were enrolled (PsA/PsO 43/33). MetS and LF prevalence were similar between PsA and PsO (35% vs 33%, p\u2009=\u20090.88; 31% vs 28%, p\u2009=\u20090.77, respectively). NAFLD was more frequent in PsO (65% vs 35%, p\u2009=\u20090.044). In multivariable models with NAFLD and LF grading as outcomes, arthritis was not a significant predictor, while HOMA was independently associated with both (OR 1.34; 95%CI 1.06, 1.69; beta 0.88; 95%CI 0.54, 1.21, respectively). Female sex was independently associated with LF grading (beta 1.81; 95%CI 0.05, 3.57). CONCLUSIONS: NAFLD was more frequent in PsO, but MetS and LF prevalence were similar in PsA and PsO. Insulin resistance is the main determinant of NAFLD and LF, while additional contribution of arthritis seems small. Key Points \u2022 The prevalence of metabolic comorbidities, including liver fibrosis, is overall quite similar between psoriatic arthritis and psoriasis. \u2022 NAFLD is more frequently found in psoriasis than psoriatic arthritis. \u2022 The contribution of arthritis in the onset of metabolic comorbidities seems small
