The current study revealed a significant increase level of TAFI and PAI-1, coupled with a decrease in PAI-2 in women with severe preeclampsia in comparison with the control group.
Cigarette smoking has been shown to be associated with changes in coagulation factors in the circulation and the subsequent thrombosis development. In this study, the impact of waterpipe smoking on the levels of fibrinogen, factor VII (FVII), and factor VIII (FVIII) was investigated. In addition, the effects of waterpipe smoking were compared to those of cigarette smoking and never smokers. A total of 80 male smokers (40 cigarette smokers and 40 waterpipe smokers) and 40 apparently healthy never smokers were recruited in the study. Both waterpipe smoking and cigarette smoking induced significant increases in the plasma levels of fibrinogen, factor VII, and factor VIII (p < 0.01). The magnitude of the increase in fibrinogen levels induced by waterpipe smoking was higher than that induced by cigarette smoking (p < 0.01), while similar increases were observed in other factors (p > 0.05). In addition, in the waterpipe group, the magnitude of the increase in fibrinogen and factor VIII was higher in the smokers with more than 3 years of use (p < 0.05). In conclusion, similar to cigarette smoking, waterpipe smoking modulates the levels of coagulation factors, suggesting its thrombotic potential.
Thrombophilia may be anticipated by single or combined hereditary defects in encoding genes factor V, Prothrombin, and MTHFR. The aim of this study was to determine the prevalence and associated risks of V Leiden (G1691A), Prothrombin (G20210A), and MTHFR (C677T) mutations in Saudi women with Deep Vein Thrombosis (DVT) and women with recurrent pregnancy loss (RPL). Protein C and protein S activity were measured to determine combined effects, if any. We examined 60 women with a history of DVT and 60 with RPL, extracted DNA from EDTA blood and determined three mutations by using multiplex PCR reactions followed by Strip Assay KIT. Pro C Global assay was used to determine the cutoff value [PCAT-NR = 0.80]. Protein C/S chromogenic assay was used to estimate protein C and S percentages. Frequency of Factor V Leiden G/A genotype in patients with DVT 7 (11.6%) had a significant association for DVT χ2 (OR = 5.1, P = 0.03). In women with RPL the three mutations did not show any significant association, levels of Protein C, protein S and PCAT-NR in patient groups not different from controls (P > 0.05). In conclusion, we recommend expanding on these data to provide larger-scale studies.
The glutathione S-transferase (GST) genes encode enzymes that mediate the detoxification of xenobiotics by catalyzing the conjugation of glutathione (GSH) to xenobiotic substrates. The aim of the current study is to investigate the association between GSTT1 and GSTM1 polymorphisms and chronic myeloid leukemia (CML) among Sudanese patients. Patients with CML (n = 115) were recruited to the study from the Radiation and Isotope Centre Khartoum (RICK)-Sudan. Healthy individuals (n = 104) were included as controls. Genotyping of GSTT1 and GSTM1 polymorphisms was performed using multiplex PCR. Null deletions in the GSTT1 and GSTM1 genes are common in the Sudanese population (control group), with frequencies of 33.9% and 38.2%, respectively. The frequencies of GSTT1 (OR: 3.25, 95% CI: 1.87–5.65, p < 0.001) and GSTM1 (OR: 2.14, 95% CI: 1.25–3.67, p < 0.005) null genotypes were significantly higher in CML patients vs. controls. The distribution of GSTT1 and GSTM1 null polymorphisms was not different between male and female (p > 0.01) and young and old CML patients (p > 0.05). Hematological parameters were not affected by null polymorphisms in the patient group (p > 0.05). In addition, the frequency of GSTM1 null polymorphism was lower in advanced-phase CML patients compared to chronic-phase patients (p < 0.05). The GSTT1 and GSTM1 null polymorphisms are associated with CML among Sudanese patients, independently of their age and gender.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
