A United States Army Medical Department, continuing Education program, morphology of recurrent disease and transplantation with James D Mullin's major US Air Force Medical Corps, Wilford Hall, US Air Force Medical Center, Lackland Air Force Base. Just real quick. I'd like to go back through again. What he's talking about when you get some pathological change and more likely to change in the of a graph or several things you do have to consider. Number one is transmission arts, the existence of transmission I don't think can really be argued if you go back and look at the experience of Peter when they transplant the ISS identical twins, which there really should be no reason for uh any type of his incompatibility. 17 of the 22 patients in an iso study had the I when they reviewed the his in the history, it felt that 17 to 22 had courses consistent with native arthritis. All for E M work really wasn't done. I got 17 which was felt to have native uh or native kidney. 11 reoccurred with morphological changes of arthritis and all that 11, either six or seven went on to lose their graft, all their life because of the to arthritis. So transplant, I mean transmission does exist at least in the has been well described and the autograph becomes much harder problem because here you run into the problem, the changes you see in the autograph immunity, the rejection process itself. Plus there's another very important difference between this is series and the autograph series. I mean nobody in this country, I am in Europe. Sometimes they will give autographs withhold imm suppression and H L A identical grasp in this country. Everybody with an autograph gets immuno suppression. And that obviously is gonna have some influence on the morphological and clinical expression of the transmission of arthritis. That is group. Only three of those people were treated prophylactically with uh immunosuppression for at least for the clinicians, maybe make you feel happier. It seems like at least if you start these people on immunosuppression, right. As soon as they get the kidney, you appear to uh at least delay or modify the transmission of arthritis from what we can tell. And most people that lose their kidneys and our experience and I think everybody else's experience lose their kidney through the process of rejection. Whether or not to have some degree of recurrence of arthritis or not, it seems to be minor except in a few instances in which I'll talk about and rejection, usually what gets the graft and there's other things that can cause morphological changes in the graph alluded to the Pacific auto autograph immunity. There's no reason that you couldn't form uh circulating H L A anti H L A antibodies. And if we're talking about in a minute, it's not uncommon to see deposits and graphs who did not have native arthritis. And maybe this is an example of a uh autograph immunity with immune complex disease. Like you see with some other instances and also the ischemic change you get in to cloud the picture somewhat. The pacific instance in which transmission arthritis is a real problem are focal sclerosing opathy. Again, I use that you really shouldn't even call it a arthritis. But we're going to put it in there anyway, because it's really not an inflammatory process but whether it's inflammatory or not, it destroys kidneys. This is a lady. Doctor mcfall was talking about, this is uh a patient of ours had about a three year history of Nephritic syndrome went into slowly progressive renal failure. We went back and looked at her original kidneys and some original biopsies. And what we saw was classic focus grows and the process was focal and segmental. Here, you can see the loop looks pretty good, but you will notice going on here, there's completely hypo cellar area, s matrix proliferation, adhesion to bone capsule. Here you can see some high drop at seven deposits and foam cells. A classic his focus and the plus on E M, she showed the fusion of foot processes which is the other component of this disease. This is just a higher P an area of focal sclerosis. You can see this part of the loop looks pretty good. This is the P A S stain. These sub inter deposits are highland deposits stand out very nicely. This is not me matrix. It does not have a fibular mass matrix and on silver stain, this material does not stain silver positive like Messan matrix. The deposits on E E M correspond to seven or three electron dense deposits. The exact nature of which nobody should. This is an E M on a patient with and, and from looking at this one field, it's identical to what you see in Neil's disease. An opinion of many people who have a lot more experience with E M than I do like doctors Fargo uh feel that the presence of diffuse fusion of foot process is approaching 100% is really found only in two disease entity, no matter whether there's neurotic syndrome present or not. That's Neal's disease and go what the relationship of and is to Neil's disease is unknown as a subject unto itself. This is an example of this lady's graph when it had to be removed at approximately two months. Although she had normal renal function, she had such a horrendous nephritic syndrome. But clinically, the graph had to be removed for the benefit of the patient. Here. Again, you can see the reoccurrence, this peculiar sclerosis here with some adhesions to Bowman's capsule. Here. When you're talking about foot process fusion in the graph, it comes a little different. You can get significant fusion of foot process and autograph rejection. But at least in Bush's experience in the porters usually doesn't go beyond 70%. The Nero syndromes associated with chronic rejection again, show diffuse fusion of foot processes, but they get a massive change in the sub endothelial on the basement membrane, which I talked about with you before. So this lady is showing diffuse fusion of foot processes 100% without sub endothelial changes in her basement membrane. And even though this is in a graph, I think it's a still pat of focus on E M. And then when you combine it with a light, my there's really no doubt. And this is just her most recent graph again showing a re occurrence that peculiar focus crossing. Fortunately, this time, she's not having near as much and she's able to uh maintain useful function. Despite the syndrome, the other entity in which you can see recurrence of is fairly commonly. I think the only real big series out of Minnesota five of nine Children with so called me has also been called hyper of childhood reoccurred with the disease. And they usually show recurrence of the hyper aia too if they recur with the disease in the ground. The patient of Doctor mcfall talked about priest. I really don't have any good slides on, I took some slides, but unfortunately, uh they didn't turn out very well. But I will show you some examples of me my in a native kidney, some people use the term very loosely. We use a very strict sense and it is a disease in which you get massive with beginning libation, massive enlargement of the. As you see, here are 2 to 3 times normal size and some degree of thickening the basement membrane, which may or may not show splitting. This is another example of me, you see the mark lobulation, increased massage matrix. And as you can appreciate here, this one here is the type that's showing the splitting of the basement membrane due to massage in position. Here you can see the splitting of the basement membrane. Now, when this disease reoccurs in the graph, just the presence of splitting the basement membrane is not significant to make it uh sufficient to make a diagnosed meno poly circumferential mas inter position is very common in graphs. I'm sorry, I didn't get through to the ems this morning on the graph changes. After you get that change, the next change you can go into is a circumferential masang inter position and chronic graph rejection. So you've got to see the overall changes it should be marketed, enlargement of the the prominent lobulation as well as the basement membrane changer before you can make a diagnosis of current me in contrast to the sang and peripheral basement membrane change, you can get in just chronic vascular rejection without any underlying immunological problem. Now, this is an example of me Riis here is the original basement membrane here here would be the urinary space. Here is the what happens in these people. For some reason, the cell grow out under the 703 market thicken it and then lay down a new lamb. It's usually a little thinner than the original lama dens. A very similar morphology can occur in graph rejection. So by alone, you really can't make the diagnosis of the current meris. Some of these people are memoli instead of showing a thickening of splitting the base membrane, they will show show so called electron dense deposits. And one time this was separated out of the so called electron dense deposit disease. But doctor B in France, I think most people now feel this is nothing more than just in the spectrum of variant of memos and this particular variant of memoli nephritis. The electron deposit disease seems to be even more likely to re occur almost 100%. And the French experience than the other form of me, the thing is this is so rare. You'll probably never see it. We've only seen one case I know of in any disease. Kidney in the four or five years, I've been at Hall the Kidney Bobs. I told you that the problem that comes up with trying to diagnose with chronic arthritis in the graph is a confusion that you run into with the same changes that apparently can occur with chronic rejection without an underlying immm basis immune complex or anti GB M process. This is a kidney of a five year old boy who had well documented dysplastic kidney disease. He had his original native kidneys removed at a very young age. He had nothing to suggest any type of underlying immunological problem over the next couple of years, he went into chronic vascular rejection at the time of autopsy. Those previous dark slides showed a tremendous some sang thickening and widespread thickening memories changed the basement membrane as well as widespread split in the basement membrane. But in contradistinction to me politic arthritis, those were shrunken retracted, they looked a trophic as well as showing these other changes I talked about and minopoli the is marked and large, sometimes three and four times the diameter of a normal. And I think that's part of the best way to differentiate between the memo type change you can get is a chronic rejection phenomena from those of the true recurrent memo plus the correlation of clinical and I fluorescent data. But this is this child at the time of death. You can see he does have typical widespread splitting of the basement membrane and he also has circumferential mass and positioning very similar to what we saw in that well documented case of me, he does not have deposits, the ones with me commonly will have deposits but they can be somewhat focal and may, you may miss them another disease entity that Doctor mcfall doesn't mention. And we have not, well, we have had some recurring anti GB MS but they really haven't expressed themselves moral to the patient. Went ahead and lost his graph because of rejection. But in early work of Dixon, he did have at least one rapidly progress. Arthritis re occur within the first couple of days of transplantation due to anti GB M arthritis. And this is just an example of good pastures. And the point I wanna make here, this is not in a graph. If you ever see this degree of crescent formation in a graft, you can be almost absolutely sure that that patients got recurrence of arthritis. Crescents are just not prominent and graft rejection of any type either hyper acute, acute or chronic. You may see a few scattered small crescents, but crescents of this size are just almost half of the mo or occurring to mars in the ground. And this is not again, it's not a graph, it's just a good, good pastures. But the original case of Dixon did reoccur with a morphology identical to this and this is a case of just how you might work up a a problem of the current arthritis. This patient and his graft in about six months or one year. I'm not sure. Now showed some degree of sang proliferation masang thickening as you can see here and all of these changes can occur as a part of a graph rejection. So how are you gonna try to separate them out? Well, one thing is to look around and see what are the vascular changes using? The cha changes in the due to rejection always less severe than those in the vessels. If you look in the vessels look pretty clean and yet your is showing this degree of proliferation, you really got to start thinking about Ken, does this guy have recurrent glome arthritis or at least part of this problem due to recurrent arthritis. We did E M on this particular case here. This is a basement membrane. Here you see these electron dense deposits. This is his, I mean this is his graph, you can get varying degrees of deposits and the G is a part of rejection to that again, that makes the process difficult. But our experience, we just don't see this type of the type of immune complex electron dense deposits very often and she have been correlated with arthritis if you go back and look at his original kidney. This is one that I didn't, I don't have pictures of it. But until you go back and look at the original kidney, you see he does have this is kind of a non specific sri in this case. But you know, you look at his native kidney. Doctor mcfall tells you he had on his native kidney. And then sometimes if you have ems on his native kidney, you had deposit some of those in the graph that pretty much seals the diagnosis. Well, in this case, we didn't have E M but sometimes you can take the blocks out of which we did here. And we were able to demonstrate that in his native kidney on paraffin embedded material, we were able to demonstrate again, electron dense deposits that have identical location in the basement membrane to the deposits that he's manifested in his graph here is not quite as good. This was paraffin embedded material. I know that's not very good, but considering it's coming from paraffin, it's it's uh not bad and especially you can make out the electron dens deposits right in trouble. So in this case, by doing a little detective work in correlation clinically and Doctor mcfall is helping I help him with E M and you could pretty well establish this guy did have some degree of recurrent arts. But I would predict that if this guy loses his graft, he'll most likely lose it because of rejection, not really because of the recurrent arthritis. And we just talked about previously this morning, the changes you see as part of graph rejection that can be confused with current fires. This is a typical change you see in rejection. And we've already talked about this memin change. You can see as part of chronic graph rejection which should not be mistaken for memin arthritis. I think what I'm trying to point out is right here. This is another biopsy an E M done on a graph and a patient that had documented uh dysplastic kidneys had no reason to have immune complex uh anti GB M arthritis in his graph on E E M. Although his was negative, he demonstrated some sub electron dense deposits. This is these type of closes that they look different from a classic. You seen a cut. I really don't know what their significance is. I think are very non specific, but they are seen fairly commonly in graphs. They were seen in 10 of 45 of the graphs in series in which he did E M and they occur where the patient had native fire or not. So I would just warn you on articles that are published and show a few deposits like that and try to push that off as fires. I think that may well be debris or it may, it might actually be a manifestation of a de novo uh arthritis related to uh things not transplant fires or histocompatibility change. But there's just really no way of knowing at present morphology of recurrent disease and transplantation with James D Mullin's Major US Air Force Medical Corps, Wilford Hall US Air Force Medical Center, Lackland Air Force Base was produced through the mobile facilities of the television division, Academy of Health Sciences, United States Army Fort Sam.
