COVID-19 Jabs:  Follow Up

The aHUS Alliance has created this page of resources as an initial place for the atypical HUS community to learn more about issues surrounding this rare disease during the COVID-19 pandemic.  Information about the coronavirus is fast-paced and ever-evolving, and which would make resource lists such as this incomplete, and in need of updated information, from the very moment ours was created (30 March 2020) to highlight topics of high interest in the aHUS global community.
We caution that new information about the coronavirus is learned on an almost hourly basis, so aHUS patients and family caregivers are strongly advised to regularly visit their national government’s outlets for health updates, COVID-19 guidelines, and details related to infectious disease spread in their regions.
Heath care policy, resource allocation, treatment options, drug access, and medical care situations vary widely around the world for those living with aHUS.  Given that, and the varied clinical profiles of aHUS patients, it would be almost impossible that any one particular medical protocol would be advised for those aHUS patients battling the coronavirus.
Some nations with aHUS/TMA study centres have released information specifically for this rare disease, and there are medical associations which have offered targeted information of high interest to include kidney transplants or dialysis.  COVID-19 information will evolve over time, which should bring new knowledge and necessitate frequent updates as the situation unfolds.
Updates are clearly marked, with our final COVID-19 updates added 16 December 2020.  Information and links appear in date order, newest to older posts and added by month as indicated below:

Important Note: 

Information & Research about COVID-19 changes every day, making it essential for people to monitor news in their nation.  International collaborations understandably maintain strict control over information about clinical trials, research efforts, and intellectual property relating to COVID-19 discoveries.

To keep abreast of advancements, utilize key search terms including:

convalescent plasma (antibodies)

monoclonal antibodies (synthetic)

A look at potential drugs to treat COVID-19 patients, this review include monoclonal antibodies (such as ravulizumab & eculizumab) as well as other therapeutic drugs.  Could aHUS knowledge be expanded by new information about how these drugs work to tamp down complement and reduce inflammation?

Tabbibi et al, Journal of Intensive Care (Sept 2020) Therapeutic Plasma Exchange: A potential Management Strategy for Critically Ill COVID-19 Patients
“The morbidity and mortality of the infection varies based upon patient age, comorbid conditions, viral load, and the availability of effective treatments.”  AND
“Therapeutic plasma exchange (TPE) merits consideration in the treatment of critically ill COVID-19 patients and is an avenue for clinical trials to pursue. If efficacious, faster recovery of patients may lead to shorter intensive care unit stays and less time on mechanical ventilation. Herein, we briefly discuss some of the various approaches currently being investigated for the treatment of SARS-CoV-2 with a focus on potential benefits of TPE for selected critically ill patients.”

11 Aug 2020
Nature:  Antibody therapies could be a bridge to a coronavirus vaccine — but will the world benefit? As the race to develop a vaccine against COVID-19 rages on, some researchers are focused on a short-term way to treat people with the disease: monoclonal antibodies.”  AND  “But mass-produced antibodies, routinely used to treat diseases such as cancer, are complex to manufacture and come with a hefty price tag. That risks placing them beyond the reach of poor countries.”

6 Aug 2020
Java et al (JCI Insight)  The complement system in COVID-19: friend and foe?
“We posit that (a) coronaviruses activate multiple complement pathways; (b) severe COVID-19 clinical features often resemble complementopathies; (c) the combined effects of complement activation, dysregulated neutrophilia, endothelial injury, and hypercoagulability appear to be intertwined to drive the severe features of COVID-19; (d) a subset of patients with COVID-19 may have a genetic predisposition associated with complement dysregulation; and (e) these observations create a basis for clinical trials of complement inhibitors in life-threatening illness.”

6 Aug 2020
Clinical Immunology (research):  Anti-complement C5 therapy with eculizumab in three cases of critical COVID-19
“Respiratory failure and acute kidney injury (AKI) are associated with high mortality in SARS-CoV-2-associated Coronavirus disease 2019 (COVID-19). These manifestations are linked to a hypercoaguable, pro-inflammatory state with persistent, systemic complement activation.” AND “In conclusion, anti-complement therapy may be beneficial in at least some patients with critical COVID-19.”

4 Aug 2020
Science (magazine):  Designer antibodies could battle COVID-19 before vaccines arrive
While the world is transfixed by the high-stakes race to develop a COVID-19 vaccine, an equally crucial competition is heating up to produce targeted antibodies that could provide an instant immunity boost against the virus. Clinical trials of these monoclonal antibodies, which could both prevent and treat the disease, are already underway and could produce signs of efficacy in the next few months, perhaps ahead of vaccine trials.”

Journal of Clinical Investigation:  COVID-19, microangiopathy, hemostatic activation, and complement
On COVID-19 and complement:  “Our understanding of inappropriate complement activation in human disease derives mainly from genetic mutations of complement proteins — either loss-of-function mutations in regulatory proteins that protect host tissues under homeostatic conditions or gain-of-function mutations resulting in resistance to regulatory protein surveillance”   AND  “The thrombotic microangiopathy (TMA) of the atypical hemolytic uremia syndrome (aHUS) leads to thrombocytopenia, hemolytic anemia, and renal failure. However, thrombotic events in aHUS are not confined to the kidney; 3% to 10% of patients have cardiac complications due to coronary microangiopathy, and patients often develop complications involving other organs. The most frequent mutations in aHUS are found in the regulatory protein factor H (FH), and such mutations lead to MAC-mediated endothelial injury and capillary thrombosis, which are the hallmarks of TMA.”

Risitano et al. Complement as a target in COVID-19?  
“Most patients who become critically ill following infection with SARS-CoV-2, the causative agent of COVID-19, develop acute respiratory distress syndrome (ARDS)1. The deterioration of lung function has been attributed to a maladaptive immune response rather than increased viral loads.” AND
“Complement is a key player of protective immunity against pathogens, but its excessive or deregulated activation may result in collateral tissue injury. However, complement inhibitors are currently only used in rare human diseases, such as paroxysmal nocturnal haemoglobinuria. In these unprecedented times, we would encourage all complement-dedicated pharmaceutical companies, as well as individual scientists, to actively contribute to our efforts to understand the role of complement in COVID-19.”

A Glimpse into Coronavirus History

SARS-CoV-2:  A Perspective

The 1918 influenza pandemic (sometimes called the ‘Spanish Flu’) established the first widespread use of plasma from recovering patients, known as ‘convalescent plasma’ or CBP, which was also adopted for the treatment during the Ebola outbreak in 2013 (see JAMA article).  In 2003 the SARS (Severe Acute Respiratory Syndrome or SARS-CoV) outbreak affected an estimated 26 nations, and launched study into coronaviruses as well as into possible vaccines (source: WHO).
COVID-19 like SARS or MERS is a disease caused by a form of coronavirus, a previously unknown virus known as SARS-CoV-2 which causes the disease COVID-19 (“Co” refers to corona, “vi” to virus, “d” to disease, and “19” for 2019). Reports from the frontlines of the COVID-19 outbreak note utilization of convalescent plasma, or an infusion of plasma from people previously recovered and containing antibodies against this coronavirus, as a potential therapeutic for patients seriously ill with COVID-19.  As information and research unfold, and evidence-backed data rolls in, new therapeutic options and socio-economic impact will continue to have global focus now and for future generations.

Many associations have offered information during the 2020 COVID-19 outbreak, to include medical professionals and specialists in fields of interest to the aHUS community.
Here are some examples of resources available, but many more exist to aid physicians and the public.  Many are nation-specific, so we caution readers to look for dates on materials to ensure that the COVID-19 information is updated – and to expand online research to find resources both in your nation and within international organizations.

Important Notes:
Review dates when COVID-19 information has been posted, to assure that you’re receiving the most updated and accurate details.
The aHUS Alliance suggests that you utilize online translation sites or apps to ensure that you’re viewing updated COVID-19 information, rather than depending on material that may have been translated days ago – and has become out-of-date.
Contact your medical team if you are experience what may be symptoms of COVID-19.  The aHUS Alliance, a global group of patient organizations in over 30 nations, cannot provide medical advice.
Physicians treating aHUS patients can reach out to colleagues for online professional support with the aHUS Alliance network of clinicians and investigators. Patients and aHUS family caregivers are encouraged to reach out to their national aHUS organization or to learn about the aHUS Alliance R.O.W. program to support new patient groups.
