PDSA is dedicated to enhancing the lives of patients with immune thrombocytopenia (ITP) and other platelet disorders through education, advocacy, research and support.

Patient-Centered Research Guidelines


In 2016, PDSA established Patient-Centered Research Guidelines with the goal of funding the most promising research that have the potential to raise an ITP patient’s quality of life by further understanding the pathogenesis and management of primary ITP to support development of new therapies and a cure. PDSA invites the research community to submit proposals for grants that will help us meet these goals.

The James B. Bussel, MD, ITP Young Investigator Award

Dr. James BusselThe James B. Bussel, MD ITP Young Investigator Award was established in 2017 by the PDSA Board of Directors to honor Dr. Bussel for all that he has done and continues to do to make a difference in the lives of ITP patients, their families, and his contributions to mentoring and advancing the scientific careers of promising clinical investigators.

Fellow PDSA medical advisor Doug Cines, MD, said Dr. Bussel “was a pioneer, not only of research in ITP, but for a generation of trainees who could follow his experience. His career shows that is possible to succeed scientifically and academically as a clinically oriented investigator even in rare diseases like ITP if you are persistent and have a creative mind. There are many young investigators and countless patients with ITP who have not met Jim personally and have no idea how much they owe to his contributions to research and patient care.”

The James B. Bussel, MD, ITP Young Investigator Award is competitively awarded to support excellence in academic ITP research by providing a selected student deemed to be of exceptional promise and a highly meritorious project with a $10,000 scholarship award funded by the Platelet Disorder Support Association.

Research Program: Take Action to Make a Difference

Although more is known about ITP each year and new treatments are becoming available, there are many unanswered questions. The Platelet Disorder Support Association has established a research program to support initiatives that lead to better outcomes for the people we serve.

Quality of Life

ITP Patient Assessment Questionnaire (ITP-PAQ)

In 2006, PDSA partnered with the biotechnology company Amgen in the development of the Immune Thrombocytopenic Purpura Patient Assessment Questionnaire (ITP-PAQ) because no validated disease-specific measures were available to assess health-related quality of life (HRQoL) in adult subjects with ITP. The ITP-PAQ is a 44-item questionnaire that includes scales for physical health (symptoms, fatigue/sleep, bother, and activity), emotional health (psychological and fear), overall QoL, social activity, women's reproductive health, and work.

Amgen has the exclusive copyright to the ITP PAQ but has granted PDSA license to sublease the Questionnaire.

ITP Natural History Study Registry

The ITP Natural History Study Registry is an international patient-consented registry of individuals with ITP. The registry aims to collect, store and retrieve data on the natural progression of ITP, enabling collection of data on diagnosis and treatment, management of care, quality of life, clinician reporting, and characterization of the ITP population as a whole.


Research Findings

PDSA attends major research conferences on thrombocytopenia and monitors scientific journals to report the latest research findings in the quarterly Publication and  monthly e-News.


Clinical Trials

PDSA tracks and lists the latest Clinical Trials on ITP to assure that those who want to participate are aware of these opportunities.
