Dear DR. ROACH: How does just one deal with normal immunity to COVID-19 if a person has an autoimmune ailment? Does that particular person take vitamin D3, zinc, and so forth.? — J.K.S.

Remedy: “Natural immunity” refers to the defense that is conferred after a pure an infection, as opposed to vaccination. Scientific tests have shown that security from an infection next a scenario of COVID-19 is about 80% to 85% for 6 months immediately after infection. Having said that, immunity to a different variant (these kinds of as the delta variant widely circulating at the time of this producing) from the 1 a human being was contaminated with may well be substantially fewer. It is not known how extended the immunity lasts following an infection, but it is very likely to wane with time.

There is no good proof that vitamin D supplementation reduces the likelihood of finding COVID-19 or getting a milder case or that it increases immunity. Similarly, zinc and vitamin C are undergoing additional examine, but there are not great info demonstrating usefulness as remedy or preventive for these dietary supplements.

Autoimmune disease these types of as autoimmune thyroid illness does not increase the hazard of a poor outcome with COVID-19. This is in contrast to immune deficiencies these types of as HIV or quite a few of the most important immune deficiencies, which do confer hazard of a even worse result with COVID-19 and are probable to decrease the safety subsequent vaccination or a purely natural infection that a person survives.

Nevertheless, drugs to take care of autoimmune disorders often direct to greater possibility — and much less immunity to COVID-19. That is because these drugs bring about a degree of immunosuppression. Some medications are considerably much more possible to do so than other individuals. Sad to say, health supplements have not been tested of worth.

Because there are several people today undergoing treatment method for autoimmune diseases, or who have immune deficiencies (which includes people triggered by therapy of most cancers and other disorders), vaccination and purely natural immunity are unable to secure anyone in a populace. When there is ongoing neighborhood transmission, which as I generate this is raising in all 50 states, additional protecting steps, this sort of as social distancing and mask carrying, are vital.

Dear DR. ROACH: My niece died at age 65. She was originally diagnosed with Parkinsonism but in the past calendar year of her life she was identified with various procedure atrophy. She experienced been a pretty balanced person, ingesting well and exercising on a regular basis. Prior to her prognosis, I experienced not read of MSA. We do not know of any other family members users with this. Are the chance factors for this affliction regarded? — P.W.

Solution: I am sorry to hear about your niece.

Numerous program atrophy is a group of unusual, lethal, degenerative neurological disorders. Prevalent to these diseases are some attributes that resemble Parkinson’s ailment, such as a tremor, slowed actions and instability. In some cases of MSA, the Parkinsonian signs and symptoms predominate. However, in MSA, there are profound abnormalities in the autonomic anxious technique, the section of the nervous procedure that regulates blood strain, urinary functionality and breathing. The blood strain complications can be really disabling, triggering large drops in blood stress when standing. Urinary incontinence takes place in most persons with MSA, and popular respiration conditions contain snooze-related conditions these kinds of as slumber apnea and REM rest habits dysfunction, in which men and women move violently during desires.

Though there are scarce familial situations of MSA, there is not a crystal clear genetic induce, nor have there been convincing studies of environmental exposures to cause this luckily exceptional group of situations.

A neurologist with distinctive expertise is the best medical doctor leader to handle this trouble, but many other experts are handy, which includes physical and occupational remedy, and a speech and swallowing professional.
