Genetic polymorphism of interleukin-1 receptor antagonist in Type 1 diabetic children.

BACKGROUND: Interleukin-1 receptor antagonist (IL1RN) variable number tandem repeats (VNTRs) are not fully understood in Type 1 diabetes mellitus (T1DM). It may affect IL1RN level and modify the disease risk. We aimed to study IL1RN VNTR polymorphism in Egyptian children with T1DM to clarify its potential role as a risk factor for T1DM and its effect on plasma IL1RN level. METHODS: A case-controlled study including 200 children (120 T1DM and 80 controls) was carried on. All children were subjected to genotyping of IL1RN VNTR. Plasma IL1RN was estimated by ELISA. RESULTS: The A1A2 and LS genotypes and A2 allele were significantly higher among cases compared to controls with increased T1DM risk (OR = 5.35, 2.56 and 3.13, respectively). The S allele was significantly elevated in cases compared to controls with 2.09-fold increased risk of having T1DM. The median plasma IL1RN significantly decreased in cases compared to controls. Within cases, IL1RN was significantly decreased in LS versus LL genotype. CONCLUSIONS: There is a strong relationship between IL1RN VNTR and T1DM in Egyptian children. A1A1 genotype, LL genotype, A1 allele, and L allele were protective. A1A2 and LS genotypes, short (S), and A2 alleles were risk factors. IL1RN was decreased in T1DM, especially in LS genotype. IMPACT: The relationship between IL1RN gene polymorphism and risk for T1DM among Egyptian children. Plasma IL1RN protein level in T1DM. Low IL1RN protein level in T1DM patients could be therapeutic targets for IL1RN medications in the future.

Assessment of Serum Level of Interleukin-37 in Asthmatic Children at Benha University Hospital.

Asthma is a complex inflammatory disease, characterized by airway hyperresponsiveness, inflammation, and reversible airway obstruction. Interleukin-37 (IL-37), functions as a fundamental inhibitor of innate inflammatory and immune responses, and it is an important cytokine in the control of asthma by suppressing the production of inflammatory cytokines. This study aimed to reveal the possible role of IL-37 in asthma through assessment of its serum level in controlled and uncontrolled asthmatic children as compared to controls. Serum IL-37 level was measured by ELISA. The serum level of IL-37 was significantly lower in patients than controls and in uncontrolled than in controlled asthma (P < 0.001). It is concluded that there is negative relation between serum level of IL-37 and asthma, which is more evident in uncontrolled asthmatic group, this observation may support the protective role of IL-37 in immune pathogenesis of asthma.

Medical errors in neonatal intensive care unit at Benha University Hospital, Egypt.

This study was conducted in the neonatal intensive care unit of Benha University Hospital, Egypt from 1 August 2012 to the 31 January 2013 to identify medical errors and to determine the risk factors and consequences of these errors. Errors were detected by follow-up of neonates and review of reports including nursing followup sheets, resident progression notes and investigation reports. We detected 3819 errors that affected 97% of neonates. Types of errors included 403 medication errors (10.55% of total errors), 652 errors in daily routine procedures (17.07%), 1042 errors in invasive procedures (27.28%), 68 errors in nutrition (1.78%), 63 equipment errors (1.64%), 260 administration errors (6.8%), 656 staffing errors (17.18%), 107 environmental errors (2.8%), 448 infection control errors (11.73%) and 120 nosocomial infection errors (3.14%). Medical errors were high in low birth weight, low gestational age neonates and increased with duration of admission.
