| T17 |
1332-1530 |
Sentence |
denotes |
Within the TNF-β genotype, 11.84% (n=25) of the patients were homozygous recessive for TNFB1, 41.23% (n=87) were heterozygous, with TNFB1/TNFB2, and 46.91% (n=99) were homozygous dominant for TNFB2. |
| T18 |
1531-1648 |
Sentence |
denotes |
The incidence of post-operative sepsis was significantly (p=0.01) higher in patients homozygous for the TNFB2 allele. |
| T19 |
1649-1893 |
Sentence |
denotes |
When compared with patients carrying at least one TNFB1 allele (TNFB1 homozygous and heterozygous genotype), the TNFB2 homozygous genotype was associated with an odds ratio (OR) of 2.60 (p=0.005; 95% CI 1.32-5.15) for the development of sepsis. |
| T20 |
1894-2025 |
Sentence |
denotes |
As compared with that for the heterozygous genotype, the OR for the homozygous TNFB2 genotype was 3.00 (p=0.003; 95% CI 1.39-6.44). |
| T21 |
2026-2221 |
Sentence |
denotes |
In patients with post-operative sepsis, serum concentrations of TNF-α were significantly higher (p=0.02) in TNFB2 homozygous individuals than in those of individuals of the other TNF-β genotypes. |
| T22 |
2222-2233 |
Sentence |
denotes |
CONCLUSION: |
| T23 |
2234-2330 |
Sentence |
denotes |
The development of sepsis was associated with a greater capacity to produce TNF-α after surgery. |
| T24 |
2331-2479 |
Sentence |
denotes |
The Nco1 polymorphism of the TNF-β gene was associated with the development of post-operative sepsis with an increased serum concentration of TNF-α. |
| T25 |
2480-2610 |
Sentence |
denotes |
In patients without post-operative sepsis, polymorphism of the TNF-β gene was not related to different levels of TNF-α production. |
| T26 |
2611-2815 |
Sentence |
denotes |
This indicates an association between polymorphism of the TNF-β gene and post-operative sepsis, suggesting the TNFB2/B2 genotype as a high-risk factor for the development of sepsis after elective surgery. |
