What this trial studies

This study aims to treat recurrent ligneous conjunctivitis in children with congenital plasminogen deficiency using aliquoted allogenic plasma. The treatment involves applying donor plasma to the eyes multiple times a day for a duration of 2 to 6 months, depending on the severity of the condition and the patient's response. The goal is to prevent the recurrence of pseudomembranous lesions that can lead to vision loss and other complications. The study will enroll one patient at the University of Saskatchewan.

Who should consider this trial

Good fit: Ideal candidates for this study are children under 18 years old diagnosed with plasminogen deficiency and experiencing ocular involvement.

Not a fit: Patients who are 18 years or older or do not have plasminogen deficiency or ocular manifestations will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve eye health and prevent blindness in children suffering from plasminogen deficiency.

How similar studies have performed: While this approach is based on existing clinical data showing the effectiveness of plasminogen replacement, the specific use of allogenic plasma for this condition is novel and has not been extensively tested.
