aHUS Baltimore meet-up

This was such a wonderful weekend and a great experience in Baltimore for those in attendance at the meet-up.  I was lucky to meet a few other patients, and some amazing caregivers.  I'm always so blown away by the sense of community we all have and how much we all have to bring to the table.  The hotel was beautiful, and I had never been to Baltimore, so it was exciting to finally get to see the great city! 

Friday we had dinner, which was delicious!  We also got to hear Diane…

aHUS Across America: Your State’s Video Clip Entry

Hello Everyone! My name is Alyssa Deffenbaugh and I am hoping to put together an video for Rare Disease day with all of us aHUS patients.  I am basing my idea on a video that Jimmy Fallon (NBC televsion:  Late Night with Jimmy Fallon) put together during the Superbowl last year – the campaign was called ‘Subs Across America’ and featured Subway Footlong sandwiches.  If sandwich lovers can grab the spotlight, why not not ask the aHUS community to raise Rare Disease Day awareness with…

Hi everyone.

My name is Alyssa, and I was diagnosed with aHUS in January of this year. It has been a terrible year, I spent the first three months of it in and out of the hospital, and very very sick. Things are looking better right now (Knock on wood), I usually feel pretty good, other than always being so tired. I am waiting for a kidney transplant, but in the meantime I am going to Iowa for some further genetic testing. I have already done some genetic testing, and they came back with a… Continue

Hi Alyssa,

We just began a newly featured forum for adult aHUS patients, if you'd care to check it out.  Hope all is well with you and your family!


'Our thanks to Jennifer Christopher for starting this important aspect of outreach and discussion among aHUS adults!  Her insight has highlighted a need for a dedicated 'Forum for Adult aHUS Patients', so please visit our newly featured forum for adult aHUS patients to share their journey and to post concerns and questions.

Welcome to the site, Alyssa. I hope that you find some answers to your questions. There are a few adult aHUS patients on this site, one being my sister Desiree Mayne. She was diagnosed 8 years ago (28 yrs. old) and after 3 years of hemodialysis she had a successful transplant and is a fellow upstate NY resident. Her diagnosis was post partum aHUS with Factor H, MCP, and Factor I mutations. My son, Ryan, has also suffered from aHUS for 7 1/2 years. We are here to help with any questions you may have. Good luck with everything.

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.

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.
