Key result
Platelet indices (MPV, PDW, P-LCR) were significantly higher in primary thrombocytosis and immune thrombocytopenia compared to other causes (P=0.000), with MPV showing 97% sensitivity for ITP.
Why the study?
Platelet count disorders often lack a single diagnostic finding and may require invasive bone marrow examination, while readily available platelet indices may provide important information to differentiate mechanisms of platelet disorders.
Can platelet indices (MPV, PDW, P-LCR) differentiate between different causes of quantitative platelet disorders in adult patients?
Population
160 adult patients with quantitative platelet disorders (80 with thrombocytopenia, 80 with thrombocytosis) from 3 Iraqi hematology centers
Comparison
Different platelet indices across quantitative platelet disorders
Design
Prospective cross-sectional study

p-value: p=0.000
Platelet indices such as MPV, PDW, and P-LCR are useful, readily available parameters for differentiating between causes of thrombocytopenia (e.g., ITP vs hypoproductive) and thrombocytosis (primary vs reactive).
Al-Tameemi et al. (2022) conducted a cross-sectional in Quantitative platelet disorders (n=160). Platelet indices (MPV, PDW, P-LCR) vs. Hypoproductive thrombocytopenia and reactive thrombocytosis was evaluated on Differentiation of platelet quantitative disorders (p=0.000). Platelet indices (MPV, PDW, P-LCR) were significantly higher in primary thrombocytosis and immune thrombocytopenia compared to other causes (P=0.000), with MPV showing 97% sensitivity for ITP.
