Functional and prognostic relevance of -173 G/C gene polymorphism of macrophage migration inhibitory factor in sepsis patients in Egyptian intensive care units

This study aimed to evaluate the association of plasma MIF level and -173 G/C single nucleotide polymorphism of the MIF gene with the occurrence, severity and mortality of sepsis patients. A study was conducted in adult surgical intensive care units of Zagazig University Hospitals, Egypt on 25 patients with sepsis, 27 with severe sepsis and 28 controls. Gram-negative bacilli were the most common isolates in both severe sepsis [63.0%] and sepsis [56.0%] patients. A highly statistically significant difference was found in MIF levels between sepsis cases and controls and a statistically significant difference as regards MIF level in different genotypes of the studied groups. MIF level was significantly associated with mortality in sepsis cases. High MIF levels and MIF -173G/C gene polymorphism are powerful predictors of the severity of sepsis and its outcome

Epidemiological characterization of P. aeruginosa isolates of intensive care units in Egypt and Saudi Arabia

This study aimed to characterize Pseudomonas aeruginosa isolates in 2 intensive care units in Egypt and Saudi Arabia. P. aeruginosa isolates from patients' and staff hands and environmental samples were typed using antibiotyping and ERIC-PCR. In Egypt, isolates from suction apparatus tubing and drainage containers [A7] and AV tubing [A8] were linked to those from patients who had these antibiotypes. In Saudi Arabia, isolates from suction apparatus tubing [A6] and AV tubing [A7] were linked to patients with the same antibiotypes. In Egypt, patients' isolates had ERIC VII, VIII and IX patterns linked to suction apparatus tubing, AV machine tubes and drainage containers. In Saudi Arabia, patients' isolates had ERIC VIII and XI patterns linked to suction apparatus tubing and AV machines. In Egypt and Saudi Arabia, ERIC typing gave higher discriminatory indices [0.801 and 0.785 respectively] than the antibiotyping [0.7123 and 0.728 respectively]. ERIC was superior to antibiotyping and should be used in tracing sources of infection
