Azithromycin as an Adjunct to Corticosteroids in Children With Newly Diagnosed Immune Thrombocytopenia
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.

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.

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

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
