About The Global Paroxysmal Nocturnal Hemoglobinuria (PNH) Patient Registry



Paroxysmal Nocturnal Hemoglobinuria (PNH) is a rare blood disease that causes red blood cells to break apart1. PNH is characterized by destruction of red blood cells (hemolytic anemia), blood clots (thrombosis), and impaired bone marrow function (not making enough of the three blood components). PNH affects 1-1.5 persons per million of the population. It can appear at any age and in any race or gender. It is most often diagnosed in people in their 30s and 40s. Aplastic Anemia is the only known risk factor for developing PNH and people with PNH can share symptoms with aplastic anemia patients, such as low blood cell counts. Treatment for PNH varies based on severity of symptoms.

The Global PNH Patient Registry is an online registry for patients with PNH. It will be hosted by the National Organization for Rare Disorders, Inc. (NORD®); an independent non-profit patient advocacy organization dedicated to individuals with rare diseases and the organizations who serve them and as such is committed to the identification, treatment, and cure of rare disorders through programs of education, advocacy, research, and patient services. The registry will collect information from participants, (or their authorized respondents, heretofore referred to collectively as “participants”), who are affected by PNH. Aplastic Anemia and MDS International Foundation (AAMDSIF), owns the registry and is the world’s leading nonprofit health organization dedicated to supporting patients and families living with aplastic anemia, myelodysplastic syndrome (MDS), paroxysmal nocturnal hemoglobinuria (PNH), and related bone marrow failure diseases. The Foundation provides answers, support, and hope to thousands of patients and their families around the world.

The primary aim of the Global Paroxysmal Nocturnal Hemoglobinuria (PNH) Patient Registry is to conduct a prospectively-planned and efficient natural history study that will result in a more comprehensive understanding of the disease and its course and pace over time. Other registry objectives include the following:

● Provide a convenient online platform for participants (or caregivers) to self-report cases of PNH.
● Develop a communications registry within the Global PNH Patient registry (e.g., to notify patients of research studies and clinical trials).
● Characterize and describe the Global PNH population as a whole, enhancing the understanding of disease prevalence and phenotype as well as the rate of progression of disease characteristics.
● Assist the PNH community with the development of recommendations and standards of care.
● Be a case-finding resource to be used for researchers who seek to study the pathophysiology of PNH, retrospectively collate intervention outcomes, and design prospective trials of novel treatments.


What is a Patient Registry?

A patient registry is an online data system that systematically collects, stores, and retrieves patient data for analysis in research studies.  The Global PNH Patient Registry serves to:

 What types of data will be collected in the Global PNH Patient Registry?  Is the data secure?

The Global PNH Patient Registry collects data on the following topics:

After completion of baseline surveys, participants may also select to receive a digital gift card totaling $75 USD as a thank you for your participation.

The registry follows strict government guidelines to assure patient information is protected. The platform is served over HTTPS, which provides traffic encryptions so as to prevent eavesdropping and man-in-the-middle attacks. Communications between the registry platform application server and the database are also encrypted.
