Brief Summary

CD163 is a member of the scavenger receptor cysteine-rich family (SRCR) is exclusively expressed on cells of the monocyte lineage.CD163 acts to amplify inflammation and serves as a critical mediator of inflammatory response in the context of sepsis. This study was designed to investigate whether CD163 genomic variations were associated with the prognosis of sepsis. We sequenced 30 sepsis patients with CD163 gene of seventeen exons by PCR sequencing. When analyzing the results of sequencing, we found five gene polymorphisms located in exon-2,exon-5 and exon-11, respectively. Compare with the NCBI dbSNP and Hapmap database, one polymorphisms located in exon-2 is non-synonymous variation rs3210140, two polymorphisms located in exon-5 are synonymous variations rs4883264 and rs4883263, the last two located in exon-11 are synonymous variations rs61729512 and rs150018775 . Five common polymorphisms (rs2234237,rs2234246) within the CD163 gene were detected in 200 patients with severe sepsis and in 200 healthy control subjects. This study was explored that whether or not polymorphisms detected within the CD163 gene may play a major role in the predisposition to prognosis of sepsis in a Chinese Han cohort.

Study Population

All subjects were selected from among inpatients who were hospitalized between September 2009 and October 2011 in the Respiratory ICU, Surgical ICU, and Emergency ICU, Chinese People's Liberation Army (CPLA) General Hospital.

You may qualify if:

• Sepsis met the criteria recommended by 1991 ACCP/SCCM Joint Meeting and by the diagnostic criteria developed at the 2001 International Sepsis Definition Conference.

You may not qualify if:

• (1) younger than 18 years of age; (2) acquired immunodeficiency syndrome; (3) reduced polymorphonuclear granulocyte counts (\< 500 μL-1); (4) died within 24h after admission into the ICU, or refused to participate in the study, or declined treatment during the period of observation.
