Methods: The medical records of 45 women with a history of RPL and 45 women who gave birth without RPL were reviewed retrospectively from three governmental hospitals in Yemen. The personal, obstetric and complete blood count reports were analyzed. Results: Platelets' count and indices were significantly higher among RPL patients when compared to the control and the receiver operating characteristic curve for each platelet index showed significant area under the curve, with higher area for plateletcrit followed by platelet distribution width and then mean platelet volume. While the multiple logistic regression analysis for all platelets indices revealed that the platelet distribution width was the significant predictor for RPL in this study. Conclusions: The use of platelet indices may help gynecologists in predicting high risk pregnancy (pregnancy loss) in the low resources areas inYemen.展开更多

There is no “gold standard” test that can establish the diagnosis of primary ITP. Therefore, the diagnosis is one of exclusion and is based on patient history, physical examination, complete blood count, and blood smear review. Platelet indices are biomarkers of platelet activation, allowing extensive investigations focusing on the diagnostic and prognostic values in various diseases without extra-costs. Mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) were investigated aiming at evaluating the correlation between pre- and post-treatment values in ITP patients. The sensitivity and specificity of platelet indices for assessment of their predictive value for treatment response were also evaluated. Methods: Fifty newly diagnosed primary ITP patients were selected from the Hematology Clinics of Ain Shams University Hospitals and classified into pediatric and adult groups. Platelet count, MPV, PDW, PCT have been recorded for all pre and post-treatment CBC samples using Beckman Coulter LH750 analyzer. Results: In pediatrics post-treatment MPV and PDW were significantly decreased while PCT was increased when compared to their values at the time of presentation (P < 0.01). The same results were obtained in adult patients, except for PDW which did not attain any significance. A significant correlation was found between pre-treatment values of these platelet indices and treatment response in pediatrics, while no significance was found between pre-treatment PDW and treatment response in adults. Conclusion: Increased pre-treatment MPV and PDW, and decreased PCT can provide diagnostic and predictive value for treatment response in ITP patients.展开更多
