Study summary

The aim of the study is to evaluate the effectiveness and safety of the application of pathogen inactivated RBC suspension in children with oncological and hematological diseases.

Read the detailed description

Assumed scope of study:

The study will include 70 patients: 35 patients to the test group, who will get transfusions with pathogen-inactivated red blood cell suspension; 35 patients to the control group, who will get transfusions with irradiated red blood cell suspension.

Methods:

  • Selection of patients suitable to participate in the study.
  • A few days before the assumed transfusion date, select/prepare a red blood cell suspension corresponding to ABO and Rh systems, with no more than 14 days of storage. Conduct direct antiglobuline test (DAT), indirect antiglobuline test (IAT) and test for individual compatibility with the patient's serum.
  • Before performing transfusion (on the day of transfusion), determine the initial indices of the patient (Hb, Hct, Haptoglobin). Determine the red blood cell suspension indices (Hb, Hct, extracellular potassium, free hemoglobin, hemolysis percentage).
  • Perform transfusion. Evaluate the presence and severity of post-transfusion reactions and complications.
  • Measure the patient's Hb, Hct, potassium and haptoglobin levels the next day after the transfusion.
  • Perform DAT 3 to 5 five days after the transfusion.
  • Perform IAT 2 to 3 weeks after the transfusion.
  • Evaluate the need for transfusions over the follow-up period (30 days).

What researchers measure

Primary outcomes

  1. post-transfusion reactions

    evaluate the presence and severity of post-transfusion reactions and complications.

    Time frame: 24 hours after transfusion

  2. augmentation of hemoglobin

    Measure the patient's hemoglobin concentration (g/dL) the next day after the transfusion

    Time frame: 24 hours after transfusion

  3. augmentation of hematocrit

    Measure the patient's hematocrit (%) the next day after the transfusion

    Time frame: 24 hours after transfusion

  4. immune responses

    Perform direct antiglobuline test

    Time frame: 3-5 days after transfusion

  5. sensitization

    perform indirect antiglobuline test

    Time frame: 2-3 weeks after transfusion

  6. intertransfusion interval

    Evaluate the need for transfusions over the follow-up period (30 days)

    Time frame: 1 months
