Prevalence of Coagulation Factors Deficiency among Young Adults in Saudi Arabia: A National Survey.

Introduction Inherited bleeding disorders vary in prevalence due to genetic disparity and ethnicity. Little is known about the prevalence of coagulation factor deficiency and bleeding disorders in middle-eastern population. Methods Young Saudi adults with at least one positive bleeding symptom reported in semi-structured validated condensed MCMDM-1vWD questionnaire were tested for complete blood count, routine and special coagulation tests, serum ferritin level, and capillary zone electrophoresis. After initial testing, those with prolonged prothrombin time (PT) or activated prothrombin time (APTT) had further testing to evaluate coagulation factors level. Platelet function was tested through platelet function analyzer (PFA)-100, and multiplate aggregometer (MEA) on patients suspected of having platelet disorders. Results Six-hundred-forty patients (male = 347, 54.2%) were included. A possible platelet function defect was diagnosed in three patients with one matching Glanzmann's thrombasthenia trait pattern, and one that of Bernard-Soulier trait pattern. One patient was diagnosed with von Willebrand disease. Deficiencies in coagulation factor levels were revealed as F-VIII in 14 (7.4%), F-IX in 15 (7.6%), F-II in two (3.3%), F-V in 17 (26.1%), FVII in two (3.1%), and F-X in one (1.8%) of study subjects; low vWF activity (<50%) was found in 14 (8%). Abnormal values were found for various laboratory tests with prolongation of platelet function analyzer-epinephrine (PFA-EPI) in 11%, PFA-ADP or arachidonic acid in 15.2%, PT in 35.9%, and APTT in 63.7%. Five-hundred-seventy-six patients (90%) had normal results in the coagulation factor assays and were categorized as patients with bleeding of unknown cause (BUC). A diagnosis of a bleeding disorder was more frequently made in men than in women (38 vs. 26). Iron deficiency anemia was found in 18 (25%) females positively associated with F-IX deficiency ( p -value 0.000). Male gender (73.3%, p = 0.007) was independently associated with the diagnosis of coagulation factor deficiency. Conclusion The current study reports a higher prevalence of coagulation factors deficiency in Saudi population than reported in the western population.

Comprehensive patient care improves quality of life in transfusion dependent patients with ß-thalassemia.

OBJECTIVES: To investigate levels of quality of life (QOL) among thalassemia patients at the Hereditary Blood Disorders Center in Al-Madinah Al-Munawarah, Kingdom of Saudi Arabia. METHODS: A cross-sectional study was performed on 43 transfusion dependent thalassemia patients compared with 43 normal subjects, as a control, using the World Health Organization Quality Of Life - Brief questionnaire between May 2012 and September 2012 at the Hereditary Blood Disorders Center, Maternity and Children Hospital in Al-Madinah Al-Munawarah, Kingdom of Saudi Arabia. RESULTS: Forty-three thalassemia patients were examined, 23 males and 20 females, and compared with 43 peers (control group), 24 males and 19 females. There was no statistical difference between patients and controls for psychological domains (53.4 versus 56.9, p=0.059) and environmental domains (56.6 versus 57.0, p=0.884). Patients had better social QOL than the control group (39.3 versus 31.7, p=0.003), while the control group had better physical QOL (55.4 versus 61.9, p=0.047). Among patients, there was no statistical difference in QOL domains for variables of age, desferroxamine use, serum ferritin level, disease severity, presence of complications; splenectomy status, hepatitis C virus status, or family history. CONCLUSION: Quality of life in thalassemia patients is similar to the control group particularly social life, though physical health is less. Improvement of patients care from all aspects will improve their QOL. More studies in this field are needed with a bigger sample size.

Portal vein thrombosis after splenectomy for beta-thalassemia major.

Portal vein thrombosis is a recognized complication after splenectomy in beta-thalassemia major due to the chronic hypercoagulable state which has been recognized to exist in childhood thalassemia and contribute to thromboembolic events. We are reporting one patient with beta-thalassemia major developed portal vein thrombosis following splenectomy.
