Who can join
Age: 9 and older, up to 22. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Hemoglobin SS, Hemoglobin Sß0thal or Hemoglobin SC documented by prior hemoglobin electrophoresis.
- Age 9 years or greater, age 22 years or less; pediatric age range, old enough to comply with mask and give reliable pain assessment score.
- Acute pain crisis defined as pain in abdomen, back and/or extremities that cannot be explained by a diagnosis other than sickle cell disease.
- Initial pain score at least 6 cm; to optimize the likelihood of observing a significant difference in change in pain score between INO treated and placebo groups. Based on data from our previous study, it is anticipated that patients will have an average pre-inhalation pain score of approximately 8 cm.
You may not qualify if…
- > 24 pain crises in the last 12 months. Patients with very frequent pain crisis may have biologic and/or psychosocial pathophysiology that differs from those with fewer pain crises.
- Pain crisis treated at a medical facility within the last 12 hours.
- Use of investigational drugs other than hydroxyurea within the last 30 days.
- Significant respiratory compromise (initial SaO2 < 90%) and/or patients likely to have acute chest syndrome (chest pain and infiltrate) will be eliminated.
- Clinically significant acute or chronic cardiac dysfunction.
- Acute priapism.
- New focal neurologic symptoms.
- Concurrent documented or suspected bacterial or parvovirus infection.
- Temperature > 38.4ºC. These patients may have concomitant infection.
- Transfusion within 30 days or chronic transfusion therapy.
- Pregnant female
- Cigarette smoker > 1/2 ppd.
- Allergy to morphine
