Prognostic Factors for Immune Thrombocytopenia Outcome in Greek Children: A Retrospective Single-Centered Analysis

Area of Science:

• Pediatrics
• Hematology
• Immunology

Background:

• Immune thrombocytopenia (ITP) in children presents with varied clinical courses, categorized by duration: newly diagnosed (<3 months), persistent (3-12 months), and chronic (>12 months).
• Prognostic factors influencing ITP progression have been studied globally, but data specific to the Greek pediatric population was lacking.

Purpose of the Study:

• To identify prognostic markers differentiating the three forms of childhood ITP within a Greek cohort.
• To analyze clinical and immunological factors associated with disease course in pediatric ITP.

Main Methods:

• A retrospective analysis of 57 Greek children diagnosed with ITP over a 13-year period.
• Data collected included age, gender, preceding infections, bleeding patterns, symptom duration, platelet counts at diagnosis, treatment, disease course, and immunological markers.

Main Results:

• The study included 39 newly diagnosed, 4 persistent, and 14 chronic ITP cases.
• Children with chronic ITP were significantly older (>10 years), exhibited a gradual disease onset, had higher platelet counts (>10 × 10^9/L), and showed impaired immunological markers compared to newly diagnosed/persistent groups.
• A recent history of infection was more prevalent in the newly diagnosed/persistent ITP groups.

Conclusions:

• While childhood ITP generally follows a self-limited course with infrequent severe bleeding, the chronic form exhibits distinct predictive parameters.
• These identified prognostic markers for chronic ITP in children can potentially aid in clinical management and prediction.
