THis one may be of interest in this connection, but beware the animal model part: Arthritis Rheum. 1998 Aug;41(8):1481-8. Related Articles, Links Asymptomatic synovitis precedes clinically manifest arthritis. Kraan MC, Versendaal H, Jonker M, Bresnihan B, Post WJ, t Hart BA, Breedveld FC, Tak PP. Leiden University Medical Center, The Netherlands. OBJECTIVE: It has been hypothesized that asymptomatic synovitis may precede clinical manifestations of arthritis in the earliest phase of rheumatoid arthritis (RA). To obtain more insight into this disease phase, we investigated the immunohistologic features of synovial tissue (ST) from the knee joints of rhesus monkeys with induced arthritis and from RA patients with both clinically involved and clinically uninvolved knee joints. METHODS: Serial ST biopsy specimens from the knee joints of 4 rhesus monkeys that had been immunized with type II collagen and ST from 10 RA patients were investigated. Eight patients without inflammatory joint disease served as controls. RESULTS: In ST from immunized monkeys, an influx of macrophages was observed well before the occurrence of arthritis. Signs of inflammation were also demonstrated in ST from clinically uninvolved knee joints of all RA patients evaluated. The ST was characterized in particular by infiltration with macrophages and by the expression of macrophage-derived cytokines. CONCLUSION: The findings support the view that asymptomatic synovitis precedes clinically manifest arthritis in both early and established RA. This implies that the debut of RA already represents a chronic phase of the disease. PMID: 9704648 [PubMed - indexed for MEDLINE] Quote Link to comment Share on other sites More sharing options...
Guest guest Posted October 19, 2005 Report Share Posted October 19, 2005 Well - all conditions have to meet some critical criteria before they become symptomatic. The meaning of subclinical is that there's a condition brewing that hasn't reached the symptomatic stage yet.. So maybe their point is that just that it's not an acute onset - Although- rRA is documentation of an infection PRECEEDING RA symptoms - so in that case you have an acute infection.... then later the person gets RA symptoms.. Barb Article said in part : QUOTE The findings support the view that asymptomatic synovitis precedes clinically manifest arthritis in both early and established RA. This implies that the debut of RA already represents a chronic phase of the disease. END QUOTE > > > > Just like CFS.

Guest guest Posted October 19, 2005 Report Share Posted October 19, 2005 Well, they are talking about histology - lab determinations, not clinical determinations - histologic abnormalities in joints which are clinically asymptomatic. However, if I read right, they arent saying they found this stuff in well people who soon got RA. Rather, they were looking at histologic abnormalities in asymptomatic joints of people who had RA in other joints. This is no huge surprise, as I think there are abnormalities in the RA lung about half the time, and I think these are usually asymptomatic. And then theres the rhesus monkey part of the investigation, where the monkey joints were histologically abnormal before they developed overt arthritis - but thats AI experimental arthritis, and I'm sure neither of us considers that to be as relevant to RA as these workers probably consider it to be. I essentially ignore that part. Apparantly there is some sort of arcane charecteristic of the RA T- cell population (other than self-reactivity) that some think indicates AI. I havent sorted that out yet. However, I dont think its very solid, as there are rheumatologists on the " sterile " side who suggest the T-cells arent even the ongoing driving force; rather they suggest that the synovial fibroblasts could just go renegade without necessarily having ongoing stimulation from the adaptive immune system. > > > > > > > Just like CFS.

Guest guest Posted October 24, 2005 Report Share Posted October 24, 2005 I wonder how many organisms are subclinical. How long they are brewing before they can not longer exist just under the radar. I read an excellent but old paper by a doctor who was referring to the diabetic process, so it was long ago, but it spoke very clearly how the disease process begins long before anyone knows anything is going on. It said that that process occurs in all disease, so the trick is to develop the patterns that different disease have in their pre- recognition stages so that medicine can provide much better solutions by the time the patient is really hurting. (my interpretation( It was sad though,in a way, I felt it completely represented another time when medicine was about cures " and helping the patient. Not about the business of medicine. I would like to have a mass mailing to all doctors of the world. After I became ill I was really stunned at the nonchalant attitude that some doctors had about not being able to help some of their patients. They almost took on an attitude of win some, lose some. One duc came within a hairs breath of admitting that he may try, but he knows that if he can't help me, he will just turn around and help the next hang nail patient in line. I felt this eerry kind of feeling as if he declared that doctor's are untouchable, because they will always be able to help at least the minor patients and redeem themselves. The article drew me in because of all this talk about calcium, except I'm trying to keep the calcium in me and I can't. But probably the littele I have is in my knees.They are hurting me so bad today, I cannot even use my hands. Go figure? I was kidding, but was referring to the problem of distraction when the pain is like this. I'm sorry to hear that your pain is on the upswing. Wouldn't it be nice if there were controlled studies into the disease process of what we face. Where we could be told that according to studies, the next dilemma would be " XXX " , but not to worry because they already were taking care of its path and destruction by giving us " XXX " solutions. I guess I'd be running true to form if I admitted that in my naive life, I still believe that is the way it is supposed to be. Did the doctor's long ago know that if they took care of the immunity and its response to the disease process of diabetes, that it would be a good representation of all disease? Did they maybe have a hint that many questions could be answered. But the everyone sold out when there wasn't any money in those solutions? I have no answers, just questions.
