Impact of polymorphism in <Emphasis Type="Italic">IL-1RA</Emphasis> gene on the risk of cervical cancer

Introduction Cervical cancer, the second most common malignancy in women worldwide, is almost invariably associated with infection by human papillomavirus (HPV). However, although many women are infected with high-risk types of HPV, only a subset of infected women will ever develop cervical cancer. Therefore, host genetic factor may play a role in cervical carcinogenesis. Several studies suggested that immunological components play a key role in the development of cervical cancer. Polymorphism in the IL-1RA gene was associated with various malignant diseases. Data are lacking for cervical cancer. Materials and methods In a case−control study we analyzed the polymorphism of IL-1RA in 150 women with cervical cancer and 209 healthy controls. Genomic DNA fragments were amplified by PCR. Results There was a strong significantly protective association between heterozygous AB genotype and HPV 18 (OR = 0.11, 95% CI = 0.04–0.30, p = 0.0000000). Similarly this result was demonstrated, in combined AB + BB genotypes of IL-1RA with HPV 18 (OR = 0.12, 95% CI = 0.05–0.30, p = 0.0000000) and HPV type 16 + 18 (OR = 0.18,95% CI = 0.08–0.38, p = 0.000005). We found high protective significant association between heterozygous genotype AB with adenocarcinoma (OR = 0.19, 95% CI = 0.09–0.40, p = 0.0000002) as well. Conclusion These findings therefore suggest that the IL1-RA polymorphism is associated with cervical cancer.     

Interleukin-1β induced by Helicobacter pylori infection enhances mouse gastric carcinogenesis

Interleukin-1β (Il1b) is considered to be involved in Helicobacter pylori (HP)-induced human gastric carcinogenesis, while the role of its polymorphisms in gastric cancer susceptibility remains controversial. Here, we aimed to clarify the role of HP infection-induced IL1B in gastric inflammation and carcinogenesis using Il1b^−/− (Il1b-null) mice. In gastric mucosa of the Il1b^+/+ (WT) mice, HP infection induced Il1b expression and severe inflammation. In contrast, in Il1b-null mice, recruitment of neutrophils and macrophages by HP infection was markedly suppressed. In a carcinogenicity test, the multiplicity of gastric tumors was significantly suppressed in theIl1b-null mice (58% of WT; P < 0.005). Mechanistically, HP infection induced NF-κB activation both in the inflammatory and epithelial cells in gastric mucosae, and the activation was attenuated in the Il1b-null mice. Accordingly, increased proliferation and decreased apoptosis of gastric epithelial cells induced by HP infection in the WT mice were attenuated in the Il1b-null mice. These results demonstrated that the IL1B physiologically induced by HP infection enhanced gastric carcinogenesis by affecting both inflammatory and epithelial cells.

Is endotoxin and cytokine release related to a decrease in gastric intramucosal pH after hemorrhagic shock?

Objectives: (a) To investigate the relationship between gut ischemia parameters (gastric intramucosal pH [pHi], mucosal–arterial carbon dioxide difference [PCO₂-gap]), and endotoxin or cytokine release during hemorrhagic shock; (b) to compare the predictive value of pHi, PCO₂-gap and arterial lactate concentrations. Design: Prospective study. Setting: Surgical intensive care unit of a university hospital. Patients: 20 multiple trauma patients with severe hemorrhagic shock. Interventions: Intramucosal measurements and blood samples were obtained on admission to the emergency room and repeatedly over 48 h. Measurements and results: Endotoxin was measured using a chromogenic limulus amoebocyte assay. Cytokine [tumor necrosis factor-α (TNFα) and interleukin-6 (IL-6)] values were evaluated by immunoradiometric assays. Only 3 patients had positive blood cultures but endotoxins were detected at least once in all patients. Endotoxin levels were similar in survivors and nonsurvivors over the study period and were not related to pHi or PCO₂-gap. Initially, high levels of IL-6 were observed in both nonsurvivors and survivors [median 1778 pg/ml (range 435–44 540) vs 2068 pg/ml (range 996–92 300)]. IL-6 levels progressively decreased in the survivors but not significantly. On admission, TNFα concentrations were similar in nonsurvivors and survivors (42 ± 35 vs 46 ± 27 pg/ml). From the 24th h, TNFα values were higher in the nonsurvivors than in the survivors (24 h: 72 ± 38 vs 34 ± 17 pg/ml, p < 0.05). The greatest IL-6 levels were found for a pHi < 7.20 (28.5 ± 36.5 vs 1.8 ± 1.3 ng/ml, p < 0.05) or a PCO₂-gap > 7.5 mmHg (1 kPa) (32.5 ± 37.5 vs 1.7 ± 1.3 ng/ml, p < 0.01). With the same pHi threshold, no difference was found in endotoxin levels. The lactate concentrations were predictive for outcome from the 12th h (9.5 ± 5.9 vs 3.6 ± 2.3 mmol/l, p < 0.05). Conclusions: During severe hemorrhagic shock, endotoxin translocation from the gut was a common phenomenon that seemed independent of both pHi values and outcome. It could not explain IL-6 and TNFα release. In severe hemorrhagic shock, neither pHi nor PCO₂-gap provides additional information to the lactate measurements.
