aHUS Myths vs. Facts

"Within the last two decades, major advances in our understanding of the thrombotic microangiopathies has  greatly expanded the boundaries of our knowledge base and enabled us to view these disorders in a  fresh perspective. Misconceptions existed concerning aspects of the disease relevant to securing the correct diagnosis and selecting the optimal treatment approach."  Read more....

aHUS Center of Excellence 

The aHUS Center of Excellence is a component of the Carver College of Medicine at the University of Iowa.  The overarching objective of the University of Iowa Pediatric Nephrology Center of Excellence is to improve the healthcare of patients with atypical Hemolytic Uremic Syndrome (aHUS) and other aHUS-like diseases through a collaborative effort focused on the presentation, rapid diagnosis, underlying genetics and pathophysiology of aHUS.



Cincinnati Children’s Hospital Medical Center

Cincinnati Children’s Hospital Medical Center offers a broad platform of molecular and cellular diagnostic testing for thrombotic microangiopathies (TMA), including atypical hemolytic uremic syndrome (aHUS) and thrombotic thrombocytopenia purpura (TTP).  Test results are incorporated in a customized summary, where clinical information is incorporated with the genetic, biochemical and functional test results.

Cincinnati Children’s has board-certified pediatric nephrologists, hematologists, molecular geneticists and genetic counselors to provide telephone or email consultations to referring physicians regarding test selection, clinical interpretation, medical management and follow-up testing, genetic counseling, and additional studies of at-risk family members

SUMMARY of aHUS Outreach/Education Materials 

An overview of outreach and education materials are listed (brochures, aHUS BootcampRare Disease Resource List, and MORE!)  that offer information and insight into atypical hemolytic uremic syndrome,  a complex and ultra-rare disease.


Eculizumab (Soliris®) 

Physicians wishing to explore the use of eculizumab (Soliris®) therapy for patients with atypical HUS are advised to directly contact Alexion Pharmaceuticals, makers of Soliris ® for information related to the only drug approved by the FDA for treatment of atypical hemolytic uremic syndrome. 

FMI, call 1-888-SOLIRIS.


Alexion Pharmaceuticals provides two websites with detailed information. To learn more about aHUS, visit To learn more about treatment with Soliris, visit

 Alexion offers OneSource™, a program that provides education, assistance with access to Soliris, and treatment support for patients and their caregivers.  Each patient who enrolls in OneSource will receive one-to-one support from an Alexion Nurse Case Manager who helps coordinate care and assist with obtaining reimbursement. All Nurse Case Managers are registered nurses who have extensive experience caring for patients and working in the health insurance industry.

Rare Disease Challenges:  Support for Patients & Families     VIDEO:  Featuring Jody L. Jones, Ph.D., Clinical Psychologist  (University of Iowa, Transplant Program)

A chronic illness or rare disease diagnosis affects all individuals and groups associated with the patient. Managing medical aspects may impact family dynamics, personal relationships, professional or work areas, and other interactions across all facets of everyday life.

The video’s Resource List provides links to organizations and resources that offer assistance to those challenged with rare disease issues and concerns. Our Patient & Family Assistance Tips suggest ideas for friends, relatives, coworkers, or community members to offer support.

The Atypical HUS Foundation encourages patients and investigators to share information and explore options/resources as we work together to gain insight into this rare complement disorder. By increasing contact opportunities with researchers and medical personnel interested in helping the aHUS community, our stories foster a better understanding of atypical hemolytic uremic syndrome.

Sharing information, inspiration and support for one another, we seek to gather together people and knowledge as we strive to improve the lives of patients and families dealing with a diagnosis of aHUS.

Be proactive! Get the medical basics of aHUS, what lab values to monitor, and areas of concern...check out the "aHUS Bootcamp" and "About aHUS" tabs at the top of this page!
If your doctor has never treated a case of aHUS, please print out our 'Doc to Doc Registry' and ask him/her to contact a physician versed in the complexities of aHUS and new options for 2011 genetic testing and treatment.


NOTE: Our 'Send a Message" function on each Member's page allows for private discussion of personal content.

Did you know...

CFH (Serum Complement Factor H) is a regulatory protein. The secreted protein product of CFH consists of 20 repetitive units named "short consensus repeats" or SCRs (each approximately 60 amino acids). In patients with aHUS the last 5 "pearls" in the twenty pearl strand protein, SCR16 - SCR20, should bind to protect cells but do not- they are defective in one or more of the last 5 SCR locations. If they cannot bind or stick to the kidney to protect that tissue, the platelets clump into clots that affect the glomeruli of the kidney -potentially causing acute renal failure.
• • • • • • • • • • • •
It is estimated that there are about 2 cases of aHUS in the U.S. per 1,000,000 of population, and about 60% of aHUS patients are diagnosed as children. The condition is potentially life threatening, and either can be chronic or can recur at intervals.
