Master’s Degree Awarded to Mr. Faisal Shoay Mohammed Hajj in Hematology

Mr. Faisal Shoay Mohammed Hajj was awarded a Master’s Degree in Hematology with an average of Very Good and a grade of (89) for his thesis titled: Coagulation Profile in Yemeni Patients with Sickle Cell Anemia, which was submitted to Department of Hematology and Laboratory Blood Transfusion, Faculty of Medicine and Health Sciences – Sana’a University. The MA defense was held on Sunday, Ramadan 5, 1447 Hijri, corresponding to February 22, 2026‎.

The MA Viva-voce Committee, which was formed based on a resolution issued by the Graduate Studies and Scientific Research Council, consisted of the following:

#	Committee Members	Designation	Position
1	Prof. Mohammed Abdulwahid Al-Muraish ‎	Internal Examiner	Chair
2	Prof. Hassan Abdulwahab Al-Shamahi ‎ ‎	Main Supervisor	Member
3	Dr. Mohammed Abdu Muraish ‎	External Examiner	Member

The thesis aimed to evaluate coagulation indicators in patients with sickle cell anemia by measuring clotting ‎times (PT and APTT) and D-dimer levels, assess natural anticoagulants ‎through Protein C levels and platelet counts, and compare them with healthy controls to ‎determine hypercoagulability risks.

The findings of the study showed:

‎A clear disturbance in the coagulation process, characterized by prolonged clotting times and significantly elevated D-dimer levels, indicating continuous activation of the coagulation system even during stable conditions.
A marked decrease in Protein C levels, with further reduction during vaso-occlusive crises.

In light of these findings, the researcher recommended the following:‎

Including coagulation marker testing in the routine follow-up of sickle cell anemia ‎‎
Integrating thrombosis risk assessment into treatment protocols.‎
Conducting broader studies to enhance scientific understanding and develop more ‎effective preventive strategies.‎

The defense session was attended by a number of academics, researchers, students, colleagues, and the researcher’s family.
