| How well does our immune system fare against parasites? Posted: 25 Apr 2021 01:27 AM PDT I know that our immune system does pretty well overall against viruses and bacteria, but I read less about parasites. The ones I've learned about like malaria, trichinellosis or tapeworms seem to have no trouble infecting and surviving in the human body, but I imagine there must be some selection bias coming into play. Are there parasites (including helminths) that our body can easily get rid of -- the equivalent of common colds, flu or the other bacteria and viruses we might not even notice? I suppose a way to answer this is to look at immunocompromised patients for ones that aren't usually seen in the general population. [link] [comments]  |

| How effective is the COVID vaccine on those who are on immunosuppressives? Posted: 24 Apr 2021 09:20 AM PDT Some immunosuppressives (infusions and such) are unable to be stopped prior to getting the vaccine due to the time they stay in your system. Would this cause a decrease in the effectiveness of the vaccine due to a blunted response? [link] [comments]  |
| Why does COVID cause hypotension? Posted: 24 Apr 2021 10:21 AM PDT If membranous ACE2 is being depleted, wouldn't you expect to see more hypertension as angiotensin II builds up? Instead, there have been some reports of hypotension, particularly with those on ARBs. Now, hypotension is always a side effect with ARBs, but why would there be an increased risk after COVID infection? If anything, wouldn't the ARB dosage have to increase a little in order to keep up with the increased angiotensin II? I can't find any clear explanation online. EDIT: Similar phenomenon was observed in SARS, where people were being hospitalized for hypotension, but there is no explanation why. Why would the body go into hypotension when there's so much angiotensin II? [link] [comments]  |
