About the research

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.

Read the full description

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.

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

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.

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

What researchers are measuring

Outcome measures describe what is being studied. They are not proof that a treatment works.

Primary measures

Change in Platelet Count

Time frame: 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.

Secondary measures

Presence of Bleeding Manifestation

Time frame: 3 months after treatment

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

Change in Bleeding Severity Score

Time frame: 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).

Change in Regulatory T-Cell (T-reg) Percentage

Time frame: 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.

Change in CD4+ T-Cell Percentage

Time frame: 3 months after treatment

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

Change in CD25+ Cell Percentage

Time frame: 3 months after treatment

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