It protects the body against infections in the membranes (thin tissues) that line the airways, eyes, mouth and digestive system.. People with selective IgA deficiency don’t have this protein or have very low levels (deficiency) of the protein. Immunoglobulins are termed as a special type of globular proteins with a complex structure. Some people with IgA deficiency will recover on their own and produce IgA in larger quantities over a period of years. Immunoglobulin A (IgA) is an antibody blood protein that’s part of your immune system. IgA nephropathy is a kidney disorder that occurs when IgA (immunoglobulin A), a protein that helps the body fight infections, settles in the kidneys.

We found that COVID-19 infection was paralleled with IgA deficiency [11]. It may be caused by a mutation in a specific gene or by a drug, such as phenytoin (used to treat seizure disorders) or sulfasalazine (used to treat rheumatoid arthritis). It is assumed that IgM is the first antibody produced in response to the infection whereas IgG, which is synthesized later but shows enduring presence, has an impact on long-term immunity.
