2026年11月4日 更新者:Shaza Barakat El-helaly、Tanta University

Azithromycin as an Adjunct to Corticosteroids in Children With Newly Diagnosed Immune Thrombocytopenia: A Pilot Randomized Controlled Trial With Exploratory Analysis of Regulatory T Cells

This study aimed to evaluate the possible immunomodulatory effect of Azithromycin as an adjuvant treatment on the clinical and laboratory outcomes of children with newly diagnosed ITP through its effect on T-reg cells.

研究概览

详细说明

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by a low platelet count (< 100 × 109/L) due to enhanced platelet clearance and compromised production, typically manifesting with bleeding.

Azithromycin (AZM), is abroad spectrum macrolide antibiotic with bacteriostatic properties, it also appears to has anti-inflammatory and immunomodulatory properties that are impartial of its antibacterial properties.

描述

Inclusion Criteria:

  • Eligible participants were children aged below 12 years.
  • Patients with newly diagnosed immune thrombocytopenia (ITP) (within 3 months of onset) who were planned to receive corticosteroids as first-line therapy.

Exclusion Criteria:

  • Patients had any other cytopenia, another autoimmune disease (e.g., systemic lupus erythematosus, screened by antinuclear antibody and anti-dsDNA).
  • Secondary or suspected inherited thrombocytopenia.
  • Congenital anomalies.
  • Positive family history of thrombocytopenia, or concurrent severe infection.
  • Children who did not respond to first-line therapy and required an additional treatment line.

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Change in Platelet Count
大体时间:3 months after treatment

Platelet count was measured using a complete blood count to evaluate the hematological response to treatment. Platelet counts was compared between the prednisone plus azithromycin group and the prednisone-alone group at each follow-up assessment.

3 months after treatment

次要结果测量

结果测量
措施说明
大体时间
Presence of Bleeding Manifestation
大体时间:3 months after treatment

Bleeding manifestations was assessed clinically and recorded according to their presence or absence.

3 months after treatment
Change in Bleeding Severity Score
大体时间:3 months after treatment

Bleeding severity was assessed using the modified Buchanan and Adix bleeding score, which grades bleeding severity from grade 0 (no bleeding) to grade 5 (life-threatening bleeding).

3 months after treatment
Change in Regulatory T-Cell (T-reg) Percentage
大体时间:3 months after treatment

Regulatory T-cell percentage was assessed using flow cytometry. T-reg cells is identified as CD4⁺CD25^high cells, and the percentage was compared between baseline and post-treatment measurements.

3 months after treatment
Change in CD4+ T-Cell Percentage
大体时间:3 months after treatment

The percentage of CD4+ T cells was measured by flow cytometry to explore changes in T-cell populations following treatment.

3 months after treatment
Change in CD25+ Cell Percentage
大体时间:3 months after treatment

The percentage of CD25+ cells was measured by flow cytometry to explore immunological changes following treatment.

3 months after treatment
