Analysis of HLA-DQB1*0602 in Multiple Sclerosis Patients in Khuzestan Province, Iran.

Background: Multiple sclerosis (MS) is a chronic, demyelinating, autoimmune and also complex disease of the central nervous system the etiology of which is not completely defined; but both genetic and environmental factors are regarded as main factors in its susceptibility. HLA-DQB1*0602 is considered as one of the most important genetic factors in MS predisposition but contradictory results have been reported in different populations world-wide. Since there are no data with respect to the correlation of HLA-DQB1*0602 and multiple sclerosis in Khuzestan province, and because of ethnic diversity in Khuzestan province, the aim was to examine the association of this allele with multiple sclerosis in Khuzestan.

Causality relationships between coagulation factors in type 2 diabetes mellitus: path analysis approach.

Background: Type 2 diabetic mellitus patients are amongst the most susceptible groups to vascular abnormalities, which predominantly lead to myocardial disease. The hypercoagulable state has been widely studied by researchers as being the major suspicious mechanism facilitating the consecutive chain of molecular events leading to these complications. However, there is no consensus on the definition of the hypercoagulable state with respect to coagulation quantities, their interrelations and basic factor(s) initiating this pathogenic event, by which the prognosis of myocardial complications could be determined.

Interpretation of correlations between coagulation factors FV, FVIII and vWF in normal and type 2 diabetes mellitus patients.

Increased risk of vascular diseases in hypercoagulable states is assumed to be the major cause for prevalence of vascular problems in type 2 diabetes mellitus patient. The present study was undertaken to explore the basis underlying the correlation between the aforesaid three coagulation factors with reference to the relevant mechanistic findings using statistical calculation. Our findings showed that the correlation between each pairs of coagulation factors, FV, FVIII and vWF could be easily interpreted using previously characterized interactions between these factors.
