DIP Episode 552 - The Iron Story and The USMLEs (Part 2)

Welcome to episode 552 of the Divine Intervention Podcasts. Into this podcast we're gonna finish up our discussion on the Iron Story and the USML Es. This is gonna be part two. So we're just gonna jump right into it. So if you remember, I would encourage you if you missed it, listen to episode 550. Again, it may seem like some benign podcast. It may seem like, oh, I know everything about Iron. Until you then notice that I proceed to make like lots of integrations in that podcast. I think you're gonna find it to be extremely helpful. So just go back, listen to that if you have not listened to it. We're gonna pretty much pick up where we're left off. So let's start addressing some diseases. And honestly, my goal with today's podcast is to address a few diseases. But there is a lot of kind of weird integrations I wanna make that I think are gonna be very useful. And like you may actually hear me talking about like a bunch of things you may think have no relationship with Iron. But they're actually pretty high yield to know for the exams. And I'm gonna really focus to Leon understanding pathophase. So that this stuff kind of clicks in your brain. So I think since we have that foundation in Iron metabolism, now let's talk about some diseases. And the first one I'm gonna talk about is hereditary hemochromatosis. Hereditary hemochromatosis. As many of you know, hereditary hemochromatosis just to get the genetic stuff out of the way. It's from a HFE mutation.

And there are many different mutations that can cause this. So HFE is the gene. Very common mutation that can cause this is the C282 Y mutation. That's actually the one that is the most common. But another one that you may notice that can cause this is the H63 D mutation, the H63 D mutation. And obviously this gene mutation is on chromosome 6. Okay, chromosome 6 is the gene. Again, my goal with this podcast is to pretty much cover every base from step one to step three. And I think it's important to understand that this mutation that causes hereditary hemochromatosis, many times it's going to be a misence mutation. So you pretty much have a switch in the amino acid structure. And you switch an amino acid and you make a different protein. So remember it's not like a frame shift mutation, because a frame shift mutation, remember it's really bad. You pretty much have an insertion or deletion that's not in a multiple of three and indel. That's not in a multiple of three, you're getting trouble. You pretty much mess up the whole reading frame. And this is not a nonsense mutation where you switch up the amino acids and then you make a premature stop code on. Like you a you a you a you usually that truncates the protein structure, the peptide structure. So this is a misence mutation. So you have like a pretty much a single point mutation. But the thing that happens with that is that you make a different amino acid.

Obviously the different amino acid you make, then makes you make a polypeptide that is not as good as the original. So this a misence mutation. And one thing to know, one of the genetic principles they love to explore with this is this whole thing with a compound heterozygote. So again, I say that the most common mutation is the situate to Y. And other one is the H 63 D the H 63 D is less common, but some compound heterozygote. They can have like both the H 63 D mutation and the situate to Y mutation. They will also have clinical features of hereditiohemocomatosis, but it will not be as severe as the people that are homozygous for the situate to Y mutation. So in terms of wastes in severity, if you have a situate to Y mutation and your homozygous for it. So both genes are messed up on chromosome 6. You have both of those mutations in the HFE genome chromosome 6. That's a big problem. Second worst is going to be the compound heterozygote. So there's something I want to keep in mind. Obviously it's an autosomal recessive disease. So again, you need two bad genes to get in trouble. And again, the US release these days they are very big on demographics for disease. So don't forget Caucasians, especially Northern Europeans. They're the big, big, big foes that can get this particular problem. So many of you have probably memorized this. That hey, if a person has hereditiohemocomatosis, when you have this HFE mutation, you're going to have iron overload. Now let's explain.

Let's try to explain why you may have that iron overload. The thing is this is something that has not been fully worked out, but I'm going to try to give you my best explanation to make it make sense in your head. So the thing is you probably notice that the, you know, so HFE is a gene. So has a gene product, a protein known as HFE. And what in the world does HFE actually do? Well, the thing is HFE combines through transferring receptors. And when you bind to transfer receptors, remember we talked about this last time, episode 550, that transferring is a protein that shovels iron around in the blood. So it binds to transfer receptors and basically prevents iron that is in transferring from binding to those transfer receptors. Because remember, it would make sense that a transfer receptor is like, hey, transfer, you got iron from me, okay, come on. The transfer in binds that with the iron binds the transfer receptor. And then that way you move iron to where it needs to be, you know, bone iron and stuff like that. Right. So that's what transferring does. Okay. I mean, that's what HFE does. So HFE binds the transfer receptor and prevents iron that is in transferring from binding to that transfer receptor. So when you have a mutation, this whole system does not happen well. Basically, HFE will not be able to bind the transfer receptor properly. Okay.

So when mutated, when you have these situate to-way mutations of the H63 D mutations, HFE cannot bind the transfer receptor properly. And if you cannot bind the transfer receptor properly, then as you're going to see transferring bound to iron, we'll just keep binding to the transfer receptor. And that's a problem. That pretty much overactivates iron significantly. So let's try to look at this very logically. So the thing is, normally, again, I'm going to repeat myself, but I want to make this point very clear in your head. Normally, HFE binds the transferring receptor. When HFE binds the transfer receptor, then transferring with iron in it cannot bind the transfer receptor. That almost introduces like a bottleneck in the whole process of iron moving around the body from be reabsorbed into intestine. Remember, we said it's reabsorbed in the Diodnam for the most part? All the way to get into the bone marrow. So you put a bottleneck, the whole process, you back up the whole process. And when the process is backed up, the body is going to be like, wow, transferring that has iron in it cannot bind the transfer receptor. So let's maybe stop reabsorbing iron. That's the normal thing that's supposed to happen when HFE binds the transfer receptor.

But if you have a mutated HFE, that cannot bind the transfer receptor, then this process of backup, like, oh, kind of shutting down everything because there's this limiting step that has kind of stopped because HFE has bound the transfer receptor, this backup process doesn't work anymore. So you're pretty much going to keep the entire chain reaction going of reabsorbing iron. Over time, you keep accumulating iron, accumulating iron, accumulating iron. And then it's going to become a problem because over time, you're going to have free adequate damage from iron accumulating. Remember iron, there's this thing called the fentin reaction that it can participate in that can cause problems. So again, what's the classic vignette? I should have studied it this way actually. What's the classic vignette for here to show you more about those as well. It's going to be a guy probably in his 40s or a woman that's postmenopausal. That's going to present with a bunch of issues, right? So, you know, they may have John this, they're LF Ts may be elevated, they may have like cardiac issues, they may have arrhythmias, they may have like skin hyperpigmentation, you may notice that they may have like some joint pain. Or you know, you may see that a guy that has erectile dysfunction, believe it or not, erectile dysfunction can be a hereditryhumocromatosis representation. Are you going to see why actually in a second here? Because the thing is this iron overload, right?

When you have iron overload, iron can trigger free radical formation. And those free radicals can cause a lot of problems, right? They can cause like membrane-lippid peroxidation, they can damage a lot of stuff, right? And there's almost no place that is not going to be torched by this, right? Like for example, your liver, because your liver loves to store iron. So if that iron accumulates within your liver, that can cause cirrhosis, right? Free radical damage can have cirrhosis. That's why the LF Ts may be elevated, that's why they may develop cirrhosis. And the heart, right? The heart deals with, deals with a lot of blood, right? So iron can accumulate there, it can cause a cardiomyopathy, you can get arrhythmias from that stuff. And the thing you can see here is, you can deposit in the pancreas, you can get diabetes, because again you have free radical damage to the pancreas. When the pancreas is destroyed, your beta cells in the eyelids are longer hunts are destroyed. You'll make insulin you're going to have diabetes. Even in the skin, the iron can deposit in the skin, it can cause skin hyperpigmentation. Many of you are used to this term burns diabetes. Again, I can almost promise you that they may not use that bronze in term. In the USML East, they'll use more skin hyperpigmentation. Because again, this is a pathology people can easily confuse with cushions, right? At least an ACTH dependent cause of cushions, when a person has diabetes and skin hyperpigmentation.

But, you know, cushions is not going to cause you to have cirrhosis. Cushions is not going to cause you to have a cardiomyopathy. Cushions is not going to have, cause you to have like many of the other things that we find in people that have hair distriging chromatosis. So it's just something I want to keep in mind, right? Because remember that, you know, cortisol can, in the video, blood glucose, again, cause diabetes. And cortisol can also cause skin hyperpigmentation. If you have cushions from ACTH dependent cause, right? Like cushions disease where you have this pituitary adenoma making a ton of ACTH, right? That ACT doesn't just fall from the sky as you probably heard me say many times. It's made, concomitantly with MSH melanoside stimuli, it's in hormone from POMC. So that MSH is going to stimulate your melanoside. And you're going to have skin hyperpigmentation. Although remember, skin hyperpigmentation is not only found in cushion syndrome. You can actually also get skin hyperpigmentation in other sense of disease. In other sense of disease, or primary adrenaline, or general cortex does not work because it's being destroyed by antibodies, by anti-21 hydroxylase antibodies. So you don't make cortisol. If you don't make cortisol, you won't have negative feedback in the brain. That's also going to raise your ACTH. Again, as your ACTH is being made, MSH is being made. You have skin hyperpigmentation. This is actually something that many people get into trouble with.

They think that, ooh, skin hyperpigmentation only means that you have like addocents. You never think of this with having cortisol excess. So you can have skin hyperpigmentation on cortisol excess if it's an ACTH-dependent process. We can have skin hyperpigmentation if it's cortisol deficiency, like addocents disease, or a person that asks for a one hydroxylase deficiency, like in congenital adrenaline hyperplasia. That can cause low cortisol. Again, no negative feedback. Your ACTH will rise, your MSH will rise. Although, if a person has addocents disease, or a one hydroxylase deficiency, those people will not have diabetes. Because, again, you have low cortisol. So you're not getting that negative, or a genoc acid effect of cortisol. So actually, you're going to be hypoglycemic in many of those situations. Let's continue. Again, you see kind of closely related pathologies, but different presentations. So if you see hyperglycemia and diabetes, I see skin hyperpigmentation. We also see like gonadoproblems, as we're going to talk about, you see cardiomyopathy, think of hereditary hemocurbitosis. If you see diabetes, you see skin hyperpigmentation. You see all the things like the cushion faces, the cushionoid appearance. You see like weight gain and all those things. You know, not necessarily seroses. Think of cushion syndrome. Cortisol excess.

But if you see a person having skin hyperpigmentation, but they have hypoglycemia, and they have a dissident of like, an aldosterone deficiency, like hyponitremia, hyperkelemia, metabolic acidosis, and normal lanyangab metabolic acidosis. You want to think about a person that has a primary adrenaline sufficiency, or a person that has 21 hydroxylase deficiency. All right. So let's continue. And I guess some of you may wonder, divine man, how can I differentiate primary adrenaline sufficiency from 21 hydroxylase deficiency? Well, the thing is for a person who has primary adrenaline sufficiency, if you think about it, those people, they will have decreased levels of DHS. But we would have 21 hydroxylase deficiency. When you have that enzyme deficiency, your cortisol is going to be low. Your dose stream is going to be low, but you're actually going to have increased levels of DHS. So in a guy, let me cause precocious puberty, or in a lady, you know, in a girl, that could cause a verilization and things like that. Those DHS levels are very kind of a very good differentiator. And also there's this lab called 17 hydroxyprogesterone that is elevated in people that have 21 hydroxylase deficiency. But 17 hydroxyprogesterone is not elevated in people that have other senses because the entire general cortex is just completely shut down. Again, that endocrine mumbled jump with me, seemed like a low yield to you until pops up on you, exactly like, well, where did this come from?

So I would certainly know that if I were you. Okay, let's continue. So what else do you find in here, DHS? After that sidebar. So again, liver causes cirrhosis, heart cardiomyopathy, pancreas, diabetes, skin, the bronzing, skin hyperpigmentation. Now, another classic thing you may see with here, DHS, is actually joint problems. Now, you know, there's the classic joint you're going to see in the knees, but many times on the USM is they give you hand osteoarthritis. And one thing I've also noticed that friends at the MBM is love to throw out here where the orthopathy we find in hereditary hemochromatosis is that these people may actually have athropathy in unusual joints, like the shoulders. I mean, sometimes you hear of shoulder osteoarthritis, not very commonly, but these people can actually have those problems. And actually, you should also know that hereditary hemochromatosis has a strong association with this disease where you may have congeal calciumoses of your joints. What is that called? You have joint congeal calciumoses. You have calcium deposition in the particular cartilage of your joints. What disease is that? What disease is that? What disease is that? Try to think about it. Try to think about it. That's pseudo-gout. Something you want to keep in mind for your exams. Please don't forget. Sudo-gout is a surgery with hereditary hemochromatosis. It's also a surgery that just causes a hypercalcymia in general, because think about it if you're a hypercalcymic.

Well, maybe that excess calcium can start depositing your joints. All right, let's continue. And then, this radical damage iron accumulating can also happen in your pituitary. If you damage your pituitary, are you going to be able to make your gunadotropins? Probably not. You probably won't be able to make FSH. Probably won't be able to make LH. So if that happens, guess what? You're not going to stimulate your gunadotropic hypo-gunadism. Because you're not making FSH LH, so you're not going to stimulate your gunadotropic. Because your FSH LH is low and your gunadotropic is low. So your gunadotropic hypo-gunadism is low. And also this iron can deposit and cost-oretically damaging your actual gunad itself. So hereditary hemochromatosis is not a great disease to have. So if you want to diagnose hereditary hemochromatosis, what do you do? What do you start off with? Well, you want to go ahead and check the transferring saturation. You know, you can also check the ferritin. But if our friends at the NBME give you two of those answers, and you're like, hmm, if they tell you that, wait. They give you transferring saturation as an answer, they give you ferritin as an answer. What should you pick? Again, this is a bio-stats question in disguise. The USML is a love to do this stuff all the time. You should pick the answer that says transferring saturation. Transferring saturation is just better. It's more sensitive than ferritin. Why?

Well, the thing is, we know that this disorder is an iron overload state. So every protein that kind of holds iron like transferring is going to be saturated. But ferritin, ferritin is it only iron overload that's going to increase your ferritin? No. Ferritin is an acute phase reactant. It's meeting inflammatory states. So, yes, in hereditary hemochromatosis, your ferritin is probably going to be elevated. But elevated ferritin does not always mean you have hereditary hemochromatosis. It's not a particularly great, it's not as good as transferring saturation, I guess what I'm trying to say. So, transferring saturation is more sensitive than specific. Right? Has a higher MPV, has a higher MPV for that. No, saying hereditary hemochromatosis compared with ferritin. Ferritin is decently sensitive, has a decenn MPV. It was not very specific. Does it have a great MPV for that? No, saying hereditary hemochromatosis. Something I want to keep in mind. And again, I said that just so I don't forget this point. That hereditary hemochromatosis, we find it in men, it's that's creeping up in their 40s, women in their 60s. Or remember, the body doesn't really have any great methods for getting rid of excess iron. So, if you're a man, you're probably not means trading. So, you're going to have issues a lot earlier in life than a woman. That's like menstruating hard every month. But once a woman hits menopause, that menstruating hard every month kind of goes away.

So, around your 60s as a lady, you're going to start having problems. And obviously, if you have other risk factors for liver disease, so say for example, you're an alcoholic or whatever, you're going to start getting in trouble a lot earlier than age 40 and men or age 16 women. Kind of a similar principle, alpha and antitripsin deficiency. No, alpha and antitripsin deficiency. If you don't smoke, you're going to have a great life expectancy. But if you smoke, your life expectancy is not going to be great. You're going to have symptoms much earlier in life. And you're going to die earlier. It's just kind of the way it works. So, how do we treat hereditary? And after you've done the blood testing with the transverse saturation of heritane, you can then do a blood test where you look for that HIV mutation. So, how do we treat this? We're going to treat this with phlobotomy. We're going to treat this with phlobotomy. Sometimes on the example, they can install asking, how do you treat this? They can kind of throw it as a different question just to throw you off. They can say, which of the following interventions will most likely improve the spations, prognosis or decreased the spations risk of developing complications or decreased the spations risk of cirrhosis or whatever? So, how do we treat this disorder? Simple as that. Just again, phlobotomy. Phlobotomy is just a great way to get rid of excess iron.

You know, you can also use iron collider, but I will think of that as a second line measure. One of the things that the MBB means love to throw out with hereditary hemocromatosis is, hey, what's the most common cause of death in this disease? It's going to be liver disease. Liver disease is the most common cause of death in hemocromatosis. You can die from cirrhosis. Remember, cirrhosis can also increase your risk of hepatocelular carcinoma, so that can also be a problem as well. And remember, if you do a biopsy of an organ that has been torched, let's say, you know, like the liver, for example, I hope you noticed that, oh, divine. If they tell you something that, oh, Prussian blue steaming is positive, then that tells you that you're dealing with iron, right? Tells you're dealing with iron. So something you want to keep at the back of your mind on exams. And then one weird, bizarre thing I can almost promise you probably will never find this in a resource, but this is what I'm about to say is like extremely high yield to know for the USM at least. Is this whole concept of you see like severe sepsis? Let's say you see a person that has hereditary hemocromatosis, you know, the hotel you're present that has diabetes, has cirrhosis, has skin hyperpigmentation, and it's also hypogonatal. And then they tell you that this person has severe sepsis, you know, they went on a cruise, you know, a little seafood and whatever. What's the thing causing that severe sepsis?

I would hope you're thinking of vibrioloneficus, vibrioloneficus, vibrioloneficus. This is actually a very high yield construct to understand. So the thing is, there are certain organisms that thrive on iron. They love iron a lot. And these organisms are called ciderophilic organisms. Now, vibrioloneficus loves iron so much. So because people that have hereditary hemocromatosis have iron overload, they can actually have very, very severe vibrioloneficus infections. I know many of you know that a physician between vibrioloneficus and put a liver disease, well don't forget this association between vibrioloneficus and people that have iron excess, iron excess. Keep that in mind. You know, so people that have iron excess iron overload like hereditary hemocromatosis, they can really have nasty infections from ciderophilic organisms. So I see there, you know, kind of, it goes from iron. So vibrioloneficus is a big one you should know for your exams. Don't forget Lysteria. I also don't forget Hepsi. There's actually a weird Hepsi story I'm going to tell at the end here. It's going to clear up something that you've probably struggled with for the longest time. Now let's go to our next pregnancy. And they will probably tell you that our BDCG is positive or whatever, right? They give you physiological anemia of pregnancy. They will give you an answer that says a fully deficiency. They will give you an answer that says iron deficiency. Which one should you pick?

Well, I hope you pick iron deficiency because remember, iron deficiency is the most common cause of anemia in pregnancy. Don't get me wrong. Can you have like this almost like a physiological anemia in pregnancy? Yeah, you can. You know, because remember in pregnancy, your blood volume increases by like 50%. So that can kind of make you see my anemia because you're kind of diluting out your blood elements. But he might be enough. Eight, I would not think that that's physiological anemia. That's actually kind of bad. Right. So this person has real anemia. And the most common cause of anemia in a pregnant female is iron deficiency anemia. Actually, iron deficiency anemia is the most common anemia overall. Right. And many people always think about anemia from like a GI bleeding situation, you know, person over 50 that has like some GI malignancy or person that's had a lot of blood loss. But one area that our friends at the MBA me is actually love to test iron deficiency anemia these days. It's just from my absorption. And what would that some things that can cause you to my absorb iron and have iron deficiency anemia? Well, think of a person losing weight has a high vocal see me. You know, has a, you know, secondary hyperpropathia already saying, well, think of like celiac disease, right? Cidic disease, you kind of kill your brush border, your microbiology. So you may have issues with absorbing iron, right? Because I don't know the blood number and some parts of the journal.

But primary drug no more for your exams, right? But also don't forget a person that may have something like, I don't know, what's the thing I'm thinking about? So not just celiac disease, but if a person has like gastric bypass, right? Many people don't think about this, but when you've got gastric bypass, you literally bypass pretty big sections of your small intestine like your blood, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no I don't really ignore this concept, but how do I put this? concentration matters in a red cell. I'm going to say that again, concentration matters in a red blood cell. So if your body likes to keep a certain concentration of hemoglobin for oxygen, courage in a red cell. So it will fight tooth and nail to maintain that concentration in any way possible. So if you have iron deficiency and you have iron deficiency, well, you can make an off hemoglobin. So the hemoglobin in the red cell will start dropping. So your body is going to be like, man, how can I maintain concentration, home your stasis with my hemoglobin?

Hmm, you know what, maybe let me make my ribloxel smaller. If I make it smaller, because remember, concentration is mass over volume. So if the stuff in the numerator, the mass of hemoglobin is going down, that's killing your concentration, that's killing your MCHC.
