NCT03797495

Brief Summary

This is an Investigator initiated retrospective and prospective single cohort study. The study will utilize an international registry and develop a specimen biobank to provide an improved understanding of the natural history of hyposplasminogenemia, to elucidate the heterogeneity of phenotypic expression, identify markers to predict disease course, and inform improved therapeutic modalities

Outcome Measures

Primary Outcomes (3)

  • Define the natural history of plasminogen deficiency

    1. Recruit 100 subjects with hypoplasminogenemia and their first-degree family members 2. Collect up to 1 year retrospective and 3 year prospective data on symptoms, treatment and interventions

    2 years

  • Identify factors that contribute to or correlate with disease expression and severity

    1. Perform centralized plasminogen activity and antigen analyses 2. Perform centralized genetic analysis to identify changes in the plasminogen gene 3. Perform centralized analysis of polymorphisms that affect plasminogen activity levels and impact fibrinolysis 4. Perform local urine analysis 5. Collect samples to explore the interaction of altered plasminogen proteins with bacterial strains

    5 years

  • Create a specimen biobank

    Bank plasma, serum and DNA on consenting enrolled subjects

    15 years

Study Population

Study population will include males and females affected with hyposplasminogenemia of any age and their first degree family members (siblings and parents).

You may qualify if:

  • Signed informed consent and assent as applicable (Appendix 1)
  • A. Males or females with type 1 PD diagnosed locally with plasminogen activity levels \<50% OR B. First degree family members of a person diagnosed with type 1 PD (includes parents, siblings, half-siblings)
  • All ages included
  • Available clinical history and treatment for at least 1 year prior to entry except for infants \< 1 year of age
  • Willingness to provide samples for analysis including DNA, plasma etc.
  • Willingness to participate in prospective follow-up for up to 3 years

You may not qualify if:

  • Previous organ transplant recipient
  • Any psychiatric disorder, other mental disorder, or any other medical disorder that impairs the subject's ability to give informed consent or to comply with the requirements of the study protocol
  • Refuses to provide informed consent
  • Special patient populations, including prisoners or, are deemed medically or cognitively unsuitable for research by their treating physician
  • Inability to obtain a blood sample due to poor or limited venous access
