I know modern scientific processes require blind studies to prove effectiveness of a new drug but imagine being in a grave spot and you’re given access to a potential life saving treatment, you get some hope back that you might pull through but you end up being one of the placebo recipients. Damn.
I think it’s important to remember that you’re also talking about maybe or maybe not receiving an experimental, unproven treatment that has the potential to make things worse rather than better. If that’s the case, you’d be happy to be the one receiving placebo.
It’s just a concentrated high dose of vitamin c, though. It’s already used for other things and deemed safe. You can just buy it off Amazon.
So in the case of most trials, I’d agree. Less so with this trial, though.
Also, the article is pretty vague on the details of how much help it really wound up being.
Oh, that in no way means it’s not going to be harmful in the context of life-threatening sepsis. One of the things the study authors checked for is evidence of oxalate crystals forming in the kidneys because high dose vitamin C can cause kidney stones.
In healthy kidneys, that’s a survivable inconvenience. In a severely septic patient? Their kidneys are already not working. That could shut them down completely.
(I’m a critical care nurse. First thing I wondered about was kidney stones.)
This was actually a big topic during the AIDS epidemic back in the '80s. However, I don’t remember how they resolved that.
I think I’ve heard one semi solution is:
You end the study before people die/get permanent damage. You should have enough data at that point to show efficacy.
Then you offer All placebo people the treatment if they want it (after the study)
You are correct that this is still done in studies where efficacy is very clear.
In fact, this just happened a few days ago in a new trial of semaglutide to treat kidney disease in diabetics. With diabetes being one of the two major causes of the need for dialysis (the other being hypertension), the drug was so successful at improving kidney function that it would have been unethical to withhold it from placebo recipients.
In studies where efficacy is more marginal or harder to demonstrate, then drugs are sometimes given for “compassionate use” to people who are almost guaranteed to die otherwise, so providing an unproven treatment that may work or may harm them is less ethically fraught. That was the basis for a lot of AIDS treatments being distributed back in the day, and in fact AIDS activists were crucial to getting compassionate use rules liberalized.
I think this is important context that you don’t see in that press release (and which is why I would advise the community to favor posting studies more than news reports):
“Our findings appear to differ from those of recent randomized controlled trials, which assessed the effect of very high dose vitamin C in patients with sepsis.”
This is one 30-person trial in a sea of trials that have been pretty equivocal so far regarding high dose vitamin C in sepsis.
Also, as a critical care nurse, I’d probably be inclined to advise against using 24 hour urine output as a primary endpoint. Not that I’m saying we’re not perfect! (Lol) But there are those days when everything is so busy that the exact urine count isn’t the highest priority. Sometimes the urine output number sits in the back of your head with a binary “enough” or “not enough” tag and you might miss putting one of the times you emptied the urine bag into the computer.
I don’t love that, but the state of hospital staffing and having extremely ill human beings trying real hard to die on you sometimes forces you to prioritize things that are all important. And of the important things, as long as urine output exceeds the “enough” threshold, it’s not the most important important thing.
Not every day will be so swamped that it forces that kind of compromise, so the numbers will average out over the course of a few days, which appears to be reflected in this study.
The actual study, for reference: https://ccforum.biomedcentral.com/articles/10.1186/s13054-023-04644-x
This is a good point, and it is something that is covered under our new rules, but it hasn’t been enforced that well since there isn’t as much content.
We really appreciate comments like yours and encourage everyone to add links and quotes from the study/paper when possible. Also if you think something does not belong, please do report it and we’ll take a look :)
I actually just found the community tonight. Glad to see you here! Thanks for starting this!
(Sometimes I like to state the obvious out loud in comments because I know people don’t read the rules lol. I find it’s how development of a self-reinforcing community culture occurs organically. That was my experience with more niche communities on that other site anyway.)
For sure, it definitely helps :)
