RESUMO

Background: Interleukin?10 (IL?10) and tumor necrosis factor?alpha (TNF??) genes contribute to oncogenesis. We evaluated the influence of the IL?10 (G1082A) and TNF?? (G308A) polymorphisms on the prognosis and outcomes of Egyptian patients with acute lymphoblastic leukemia (ALL). Materials and Methods: We investigated 64 children and 76 adults with ALL, between 2016 and 2019, for the IL?10 (G1082A) and TNF?? (G308A) polymorphisms using allele?specific polymerase chain reaction and polymerase chain reaction杛estriction fragment length polymorphism. Survival analyses were performed using the Kaplan朚eier estimator and the log?rank test. Results: In children with ALL, the A allele of TNF?? and IL?10 polymorphisms was associated with older age (P = 0.04 and 0.03), more extramedullary disease (P = 0.02 and 0.001), positive breakpoint cluster region朅belson (BCR?ABL) rearrangement (p190; P = 0.04 and 0.001), and more relapse (P = 0.002). The IL?10 GG genotype was associated with higher overall survival in children (P = 0.026). Adults carrying the TNF?? A allele showed more extramedullary disease (P = 0.009) and relapse (P = 0.003). We also found a higher frequency of IL?10 A allele in adults with older age (P = 0.03), lower hemoglobin level (P = 0.04), positive BCR?ABL rearrangement (P = 0.001), more extramedullary disease (P = 0.001), more relapse (P = 0.002), and a longer time for the first complete remission (P = 0.003). Conclusion: A possible association exists between the A allele of IL?10 and TNF?? polymorphisms and poor prognosis in Egyptian patients with ALL, while the IL?10 GG genotype may be associated with better survival in children with ALL.

RESUMO

Objectives: To compare the effects of two different intravenous lipid emulsions on solubleadhesion markers in preterm infants with sepsis. Methods: This randomized controlled pilottrial was conducted from February 2016 to February 2017. 40 preterm infants with sepsiswere enrolled and assigned to receive either Medium chain triglyceride-Olive-Fish-Soy lipidemulsion (MOFS-LE) or soybean oil-based lipid emulsion (S-LE). Outcomes of the studywere changes in sICAM-1 and leukocyte integrin β2 levels, and growth after 7 days ofintervention. Results: Leukocyte integrin β2 was significantly higher in MOFS-LE group. Nostatistically significant differences were observed for sICAM-1, duration of mechanicalventilation and antibiotics treatment, and mortality rate. Conclusions: Leukocyte integrin β2was significantly higher in preterm septic neonates who received MOFS-LE

RESUMO

Aims: To screen cases of infantile cystinosis among different forms of proximal renal tubular acidosis (RTA). Study Design: Cross sectional. Place and Duration of Study: From a total of 25 families of RTA followed up in Nephrology unit of Mansoura University Children's Hospital (MUCH), Egypt, two unrelated families were diagnosed as infantile nephropathic cystinosis using clinical suspicion plus mutation analysis of CTNS gene in the period between January 2008 and November 2012. Methodology: Two families with multiple cases of infantile nephropathic cystinosis have been diagnosed. In absence of high-performance liquid chromatography and tandem mass spectrometry used for measuring intraleucocyte cystine, diagnostic tools for cystinosis used in the current work were clinical and laboratory evidences of PRTA, slit lamp detection of corneal cystine crystals and finally identification of CTNS gene mutations. All patients were subjected to routine echocardiography because of accidental discovery of heart malformation in one case. Rare mutant variant of the first family was subjected to RNA analysis which unfortunately failed, alternatively an in silico study was used to predict splice site. Results: All patients with cystinosis manifested a severe clinical course. Proband of family 1 showed two known mutations; deletion in the exon 3 (c.18_21 del GACT) and substitution in acceptor splice site of intron 11 (c.971 -12G>A). In silico study predicted an anticipated splice site that modified the open reading frame in carboxy-terminal region. Probands of family 2 were affected by ventricular and atrial septal defects in younger, and mild mitral and aortic incompetence in older patient; their DNA analysis revealed a novel nonsense mutation (c.734 G>A) which caused a premature stop codon in position 245 of protein. Conclusion: Nephropathic cystinosis has been diagnosed with ease in Egyptian population without need of sophisticated investigations. A novel mutation had been added to the list of CTNS gene variants.
