Deaths from COVID-19 primarily stem from severe respiratory complications, with marked susceptibility among older adults and those with underlying health conditions.

COVID-19's deadly wave crashing down on the immune system's functioning, revealed by scientists at Rockefeller University, USA, is a chilling reality for the victims. This stark revelation was published in the prestigious journal Science, as reported by Almaty.tv with a nod to Lenta.ru.
As per the research, a frightening 3.5% of critically ill COVID-19 patients sport genetic mutations that hinder their antiviral defense mechanisms. Meanwhile, an alarming 10% of the patients (101 out of 987 study participants) experiencing severe symptoms produce "auto-antibodies" – immune cells that attack their own defense system. It's worth noting that the vast majority of such patients are men (94%).
Researchers discovered errors in genes responsible for the production of antiviral interferons. Without a sufficient amount of these molecules, the body struggles to fight the virus. However, in numerous cases, interferons are damaged by these "auto-antibodies," mirroring autoimmune diseases such as rheumatoid arthritis or type 1 diabetes. Unlike its milder counterparts, these "auto-antibodies" are absent in patients with mild COVID-19.
Under the Immune System's Microscope
- Auto-Antibodies and Their Double-Edged Sword: Typically, auto-antibodies are the culprits behind autoimmune diseases, where the immune system mistakenly targets healthy tissues. However, in the case of COVID-19, these antibodies could potentially play a protective role, reducing disease severity. For instance, certain antibodies may offer some degree of immunity against severe COVID-19 symptoms[3].
- Sex Factors: There's some indication that women might experience milder COVID-19 symptoms due to differences in immune responses, including the presence of certain antibodies[3]. However, this doesn't explain how auto-antibodies affect disease severity in men.
- Gene Mutations and the Antiviral Arsenal: Genetic mutations can sway the effectiveness of the immune response to viral infections. Mutations in genes involved in antiviral pathways may amplify or weaken defense mechanisms, thereby impacting the severity of COVID-19[1].
- Sex-Specific Effects: While the spotlight on gene mutations affecting antiviral defense in men is dim, mutations that impair immune function can increase the risk of severe COVID-19 across both genders.
A Closer Look at Men's Battle
- Immune Response: Men normally present different immune responses compared to women, which might influence how gene mutations and auto-antibodies affect COVID-19 severity. Details on these sex-specific impacts, particularly regarding auto-antibodies, remain scarce[4].
- Genetic Factors: Scientific studies on genetic factors shaping COVID-19 severity often zero in on single nucleotide polymorphisms (SNPs) or mutations in genes related to immune function[1][4].
In essence, while auto-antibodies and gene mutations can impact the severity of COVID-19, precisely understanding their effects on men continues to pose a research challenge.
Exploring the Road Ahead
- Genetic Investigations: Probing specific genetic mutations in genes linked to immune function could shed light on how these mutations impact antiviral defense in men.
- Auto-Antibody Inquiries: Delving deeper into the role of auto-antibodies in COVID-19, particularly regarding sex differences, could clarify their impact on disease severity.
- Immune Response Studies: Unraveling the nuances of sex-specific immune responses to COVID-19 can offer valuable insights into why certain individuals face more severe consequences.
Overall, these research avenues could unlock hidden mechanisms driving COVID-19 severity, paving the way for more targeted therapeutic approaches.
- The production of auto-antibodies, which are immune cells that attack the body's own defense system, has been linked to chronic diseases such as rheumatoid arthritis or type 1 diabetes through mirroring in COVID-19 patients.
- In the context of health and wellness, understanding the role of genetic mutations affecting antiviral defense in men and the impact of sex differences in auto-antibody production could contribute to the development of targeted therapies for severe medical-conditions like COVID-19.
