To determine the prognostic significance of reactive thrombocytosis in pneumonia patients and assess its relationship with specific clinical outcomes such as in-hospital mortality and length of stay.
Key Findings:
Reactive thrombocytosis (platelet count ≥ 400 × 10⁹/L) was associated with increased in-hospital mortality.
Length of stay was significantly longer in patients with higher platelet counts, indicating a correlation with severity of illness.
Inflammatory markers such as peak CRP and D-dimer were found to correlate with increased mortality risk.
Interpretation:
Higher platelet counts in pneumonia patients indicate severe inflammation and are linked to worse clinical outcomes, suggesting a need for careful monitoring.
Limitations:
Retrospective design may introduce selection bias, potentially affecting the reliability of the findings.
Exclusion of patients with concurrent thrombocytosis and thrombocytopenia limits the generalizability of the results to the broader pneumonia patient population.
Conclusion:
Reactive thrombocytosis serves as a potential marker for severe inflammation and mortality risk in pneumonia patients, suggesting a need for careful monitoring and further investigation for clinical application.
