ABSTRACT
Objective To investigate the risk factors of upper gastrointestinal injury induced by non-steroidal anti-inflammatory drugs (NSAIDs).Methods A total of 1032 patients which used NSAIDs was selected.Patients were divided into two groups based on the condition of dyspepsia,peptic ulcer or upper gastrointestinal bleeding:the adverse drug reaction group (331 cases) and the control group (701 cases).Data of two groups on clinical presentation,laboratory test,medication and treatment were analyzed.Risk factors for the adverse drug reaction were identified by multivariable Logistic regression.Results The two groups had significant difference in age ＞ 65 years old,Helicobacter pylori (Hp) infection,ulcer history,drug overdose,combination with glucocorticoid,addicted to tobacco and alcohol history,non-specific inhibitor of cyclooxygenase(COX)-2,combination with anticoagulant,concomitant chronic cardiopulmonary disease (P ＜ 0.05).Logistic regression analysis by backward elimination method revealed that following variables retained,such as combination with glucocorticoid (OR =3.104,95％ CI 1.936-4.695),Hp infection (OR =2.768,95％ CI 2.047-3.742),drug overdose (OR =2.411,95％ CI 1.683-3.453),ulcer history (OR =1.781,95％ CI 1.278-2.480),age ＞ 65 years old (OR =1.659,95％ CI 1.237-2.225),non-specific inhibitor of COX-2 (OR =1.470,95％ CI 1.103-2.133),addicted to tobacco and alcohol history (OR =1.459,95％ CI 1.032-2.064),concomitant chronic cardiopulmonary disease (OR =1.357,95％ CI 1.008-2.143),P＜0.05.Conclusion Combination with glucocorticoid,Hp infection,drug overdose,ulcer history,age ＞ 65 years old,non-specific inhibitor of COX-2,addicted to tobacco and alcohol history,concomitant chronic cardiopulmonary disease are risk factors of upper gastrointestinal injury induced bv NSAIDs.
ABSTRACT
Objective To explore the relation between IL-10 promoter region gene polymorphism and irritable bowel syndrome (IBS).Methods By polymerase chain reaction combined with restrition fragment length polymophism (PCR-RFLP),gene type of IL-10 promoter -1082 and -819 sites in 313 IBS patients and 281 controls was analyzed.Results The distribution of IL-10-1082 and-819 allele frequencies in IBS group,control group and total was in accordance with Hardy-Weinberg equilibrium law.The frequency of IL-10-819 T allele in diarrhea subtype (79.8％) and mixed IBS subgroup (77.1％) was significantly higher than that in control group (65.7％).There were no significant differences in IL-10-1082 A/G allele frequency between each subtypes and control group (P＞0.05),however there was statistically difference between diarrhea subtype and mixed IBS subgroup (P＜0.05).The frequency of-819 T/T genotype in IBS group (51.1 ％ )was significantly higher than that of control group (40.2％),the frequency of C/T genotype was significantly lower than that of control group,and the difference was statistically significant (all P＜0.05).The IL-10-819 T/T allele frequency of all IBS subtypes was significantly higher than that of control group; however C/T allele genotype frequency of all IBS subtypes was significantly lower than that of control group,and the difference was statistically significant (all P ＜ 0.05). There was no significant difference of C/C allele genotype between subtypes (P＜0.05).There was no significant difference of -1082 allele genotype between IBS group and control group (P＞0.05).The frequency of -1082 A/A genotype in diarrhea subtype of IBS patients (93.3％) was significantly higher than that of mixed IBS subtype (82.4％),while the frequency of A/G genotype was lower than that of mixed IBS subtype,and the difference was statistically significant (all P ＜ 0.05 ); there was no significant difference between other IBS subtypes and control group (P＞0.05).Conclusion IL-10-819 promoter T/Tgenotype may be related to IBS pathogenesis.
ABSTRACT
0.05). However in OAC group, there were significant differences between EM and IM(P0.05). Conclusions RAC and OAC triple therapy could eradicate H. pylori effectively. The efficacy of rabeprazole-based triple therapy was less affected by the CYP2C19 genotype. The eradication rates of H. pylori in PM and IM were higher than that in EM.
