Abstract:
تم تصميم هذه الدراسة للتحقق من دور جينات الـ Glutathione - S - Transferase (Mu - 1) gene و(Theta) - 1 Glutathione - S - Transferase ومدى مساهمتها بخطر الاصابة بمرض الربو القصبي في محافظة ذي قار. حيث شملت (105) شخص مصاب بالربو باعمار من (20 - 69) سنة كان | This study has been designed to investigate the roles of the gens GSTMI and GSTTI the extent to which they contribute in asthma at Thi - Qar governorate. The study has been conducted on (105) patients with asthma whose ages from (20) to (69) years. (20) of them are males and (85) are females, and (110) are healthy with no infection of asthma or any sickness of respiratory system as a control group of the same ages, (60) of these are males and (50) are females. Blood samples have been collected from both groups in ampoules with EDTA and stored under temperature ( - 20) until they are used in getting the DNA from the groups. The genes GSTTI, GSTMI, and Albumin have been enlarged as internal control employing Polymerase chain Reaction (PCR). Some dangerous aspects of this disease have been investigated, the results showed that the disease in the urban areas (85. 71 %) higher than it rural areas, and Asthma among females is (80. 95%) higher than males. The results also indicated that asthma in ages (50 - 59) is more than other categories; it is (34.28%). The majority of patients are smokers with (63.80%). The study revealed that (73.33 %) of the patients have a family history with the disease while (26.66 %) have not. Statistical analysis showed that the loss of the gene GSTM1 is about three times in the patients more than the case in the control group. (OR=2.90) , while the loss of the gene GSTT1 is five fold more than it compared to the control group (OR= 5.55). The results indicated a significant effect of the loss of the two genes in having asthma in the urban and rural areas, it is six times and a half larger in the urban areas compared to the control group of the same area. Asthma probability is ten times more in the case of the loss of both genes in the rural areas compared to the control group in the same area. And no significant difference has been discovered when gene patterns of patients in both areas. The results also indicated that the probability of having asthma in male patients is two times and a half as many as it in the females when the gene GSTM1 is lost compared to the control group. While the same probability is eleven times in the case of the loss of both genes in the females as many as it the control group. The loss of Missing the gene GSTT1 is three times in the male patients and five times in the females compared to the two control groups. The results indicated significant differences when gene patterns of males and females are compared in the case of the loss of both genes. The statistical analysis indicated that the loss of both genes in the smoker patients contributes 17 fold in the probability of having the disease compared to the control group. While the probability increases four times approximately in the nonsmokers when the gene GSTM1 is lost compared to the control group (OR=3.77; 95% C1=1.69 - 8.407). No difference has been noticed in the gene patterns of the smoker and nonsmoker patients. The results indicated that the loss of both genes has been in all the age categories. No significant differences have been noticed among the gene patterns between the patients of less and those who are more than 50 years. Asthma probability has been found 7.77 times more in the case of the loss of both genes in the patients who have a family disease history compared with the control group. The asthma probability is twice when the gene GSTM1 is lost in those patients who do not have a family history disease compared to the control group. Upon comparing the gene patterns of patients according to the family disease history, there has been an effect of the loss of both genes and having a family disease history on the probability of asthma, it is almost six times when both genes are lost. The results indicated that the probability increases three times in the loss of the gene GSTT1 in the educated patients compared to control group. The probability also increases seven times when both genes are lost in the uneducated patients compared to the control group. When comparing the gene patterns of patients according to levels of education, significant differences between the educated an uneducated have been approximately twice in the loss of the gene GSTT1.
