Long COVID, where COVID-19 symptoms persist for months or years after the initial infection, has impacted millions globally. Recent research provides new insights into potential causes and treatments.
Blood Protein Signature Could Aid Long COVID Detection
A study by scientists at Imperial College London identified a distinct signature of proteins in the blood of long COVID patients, published in the journal Cell Systems [].
The researchers analyzed blood samples from over 500 people assessing nearly 1,300 proteins. They discovered a set of 27 proteins that reliably indicated whether someone had long COVID.
Many proteins were related to the complement system – part of the immune system which helps clear infections but can also cause inflammation.
“The identification of a protein signature specific to long COVID is a breakthrough finding,” said lead author Dr Claire Hastie.
The findings could lead to the first diagnostic test for long COVID, allowing patients to access treatment and support earlier.
Active Immune System Implicated in Persistent Symptoms
In a paper published in Science, a multi-institutional team found evidence that immune system activation may be driving long term complications [].
Analyzing blood from over 200 patients, they found elevated levels of immune cytokines up to 20 months after infection – which were not detected in recovered individuals.
“The findings suggest that long COVID symptoms may arise from immune system activation similar to autoimmune diseases,” said senior author Dr David Putrino.
Ongoing immune activation could explain symptoms like fatigue, brain fog and pain in long COVID patients.
The researchers are now investigating treatments that regulate immune pathways to alleviate these debilitating lingering effects.
Congress Hears Testimony From Long COVID Patients
Patients and advocates descended upon Capitol Hill this week, providing first-hand accounts of living with long COVID to Congressional lawmakers [].
Their testimony detailed struggles getting diagnosed, finding empathetic medical care, affording treatment, qualifying for disability benefits and being believed by friends, family and employers.
“We desperately need research investment, expanded medical expertise and financial assistance,” urged speaker Diana Berrent, founding member of patient organization Survivor Corps.
Lawmakers acknowledged the urgent need to accelerate research and support services for this rapidly growing patient population.
“You have my commitment that Congress will continue working across the aisle to address this crisis,” said Rep. Donna Shalala in closing remarks.
Calls for Increased Recognition and Research Funding Intensify
In an editorial published in Neiman Reports, writer Caroline Chen highlighted the detrimental impact that underestimating long COVID’s severity has on patients [].
Chen compared past health crises like HIV/AIDS and ME/CFS which were initially dismissed or misunderstood by medical professionals. Lack of research and compassionate care caused untold suffering.
“We must learn from our mistakes with other chronic conditions and address long COVID urgently and ambitiously,” Chen wrote.
Experts argue long COVID poses catastrophic health and economic consequences if disregarded, necessitating coordinated global efforts between healthcare leaders, policymakers and funding bodies to comprehensively combat this syndrome.
