Brief Summary

Background:

  • The influenza A virus can cause infections that lead to fever, cough, muscle aches, diarrhea, and headaches, and can even be fatal in some people. Seasonal influenza kills an estimated 36,000 people in the United States each year. In addition, more than 200,000 people are hospitalized for flu-related complications. Influenza A has a substantial health effect on every age group.
  • Currently, treatments are available for influenza A, but there is concern that the rate of complications or even death from this infection is still high despite treatment, and that over time this virus may become resistant to these treatments. Researchers are interested in developing a possible new treatment that uses antibodies against influenza A virus. Objectives: \- To collect plasma (the liquid component of blood containing antibodies) from people who have high levels of antibodies against the influenza A virus because they either have been previously infected with the virus or have been vaccinated against the infection. Eligibility:
  • Healthy male volunteers between 18 and 60 years of age who are eligible to donate blood.
  • Individuals must have previously either recovered from influenza infection or have been vaccinated against the infection, and may be subject to other restrictions on participating in National Institutes of Health research studies. Design:
  • Volunteers will undergo apheresis, an outpatient procedure in which researchers will collect plasma containing antibodies against the influenza virus by drawing blood into a special machine that separates blood cells from the liquid portion under sterile conditions and then returns the blood cells to the donor.
  • Volunteers will be screened with blood tests to ensure that they are eligible to participate and donate blood.
  • Volunteers are asked to undergo at least 3 sessions of apheresis; if willing, they can volunteer to participate in up to 20 sessions.
  • After plasma is collected, it will be tested to ensure that it can be used to safely develop treatments for patients who have influenza A infection.

Outcome Measures

Primary Outcomes (1)

  • Collection of Anti-Influenza A Immune Plasma

    Subjects will be scheduled for at least 3, and up to 20, plasma collection procedures.

    Individual duration is a maximum of 240 days per subject.

Interventions

High titer influenza A plasma collection for use as therapeutic plasma in influenza treatment studies.

Eligibility Criteria

Age18 Years - 60 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Male subjects with a history consistent with influenza infection and/or vaccination against influenza.

You may qualify if:

  • Provide written informed consent before initiation of any study procedures.
  • Male adults between the ages of 18 and 60 years old
  • History suggestive of having anti-influenza A antibodies (either of the following):
  • An influenza like illness (e.g. fever, chills, malaise, cough, myalgias and nausea) consistent with influenza A infection. Subjects must not be symptomatic and be at least 7 days since the resolution of fever, and must enroll within 12 months of illness.
  • Vaccination with a licensed influenza vaccine and at least 14 days following the last vaccination in the series, and enrolling within 12 months of vaccination.
  • Some subjects may meet both requirements and enrollment should be within 12 months of the most recent event (illness or vaccination)
  • Adequate clinical parameters (all of the following):
  • Afebrile (temperature \< 38 Degrees C)
  • Systolic blood pressure \> 100 and \< 180 mmHg
  • Diastolic blood pressure \> 50 and \< 100 mmHg
  • Heart rate between 50-100 beats/minute (Individual site blood establishment's SOPs may also permit healthy athletic subjects with heart rates \< 50 beats/minutes to donate plasma, and, if so, subjects with heart rates \< 50 beats/minutes may participate in this study)
  • Weight greater than or equal to 110 pounds (50 kg)
  • Adequate peripheral venous access for plasma donation (as judged by the examiner)
  • Willingness to have samples stored

You may not qualify if:

  • <!-- -->
  • Any sign of active influenza, (as judged by the investigator) including but not limited to:
  • Subjective or documented fever (\> 38 Degrees C)
  • Cough
  • Shortness of breath
  • Diarrhea
  • Has a medical history of
  • Thrombocytopenia or other blood dyscrasias
  • Congestive heart failure
  • Pulmonary hypertension
  • Bleeding diathesis or therapeutic anticoagulation
  • Human immunodeficiency virus (HIV)/AIDS
  • Hepatitis B
  • Hepatitis C
  • Known history of hepatitis after the 11th birthday
  • +82 more criteria
