1264521 Orthopedic overview of juvenile rheumatoid arthritis. 1976 Apr Juvenile rheumatoid arthritis can be classified into three forms by the extent of early involvement: (1) pauciarticular, (2) polyarticular, and (3) systemic. When this disease, in which remission is common, is properly diagnosed and appropriately treated by physical therapy, occupational therapy, drug therapy, and surgical treatment, a good clinical result can usually be expected. Only 16 of 124 children had severe persistent impairment because of the disease in one recent study;18 this number may be high, since mild cases may be unrecognized or not be referred to the study clinic. However, efforts should be directed to reducing this number of severely impaired children -- in the short run by better techniques of reconstructive surgery and in the long run by a better understanding, through research into the etiology and pathogenesis of the disease adequate to prevent or significantly alter its course. The disease may be caused by a treatable occult infective agent and may respond to an approach similar to that for rheumatic fever, which no longer fills the wards of our children's hospitals as it once did.
304264 Immunoglobulins and antinuclear antibodies in aqueous humour from patients with juvenile " 1977 Apr Aqueous humour and blood from twenty cataractous patients with chronic anterior uveitis and the monopauciarticular form of juvenile rheumatoid arthritis were tested for immunoglobulins G, A, and M and for autoantibodies, particularly those against nuclear antigens. The aqueous immunoglobulins were raised in the majority of patients even when the eyes were normal biomicroscopically. Raised IgG antinuclear antibodies were found in 85% of the aqueous samples. Information obtained from the study of aqueous humour from fourteen patients with senile cataract was used for statistical analysis of these data. The presence of high molecular weight immunoglobulins in the aqueous humour from patients with Still's disease suggests an abnormal blood-ocular barrier which may be responsible for the recurrence which follows an ostensibly treated primary attack of uveitis. The presence of antinuclear antibody in a few aqueous samples without a concomitant rise in the blood levels is suggestive of local antibody synthesis.
6256787 Collagenase activity in human synovial fluids from joint diseases of diverse etiology. 1980 The content of collagenase in latent as well as in apparent active form has been determined in synovial fluids from 21 patients with rheumatoid arthritis, 16 with non-rheumatoid inflammatory joint diseases, and 15 with degenerative joint disease. Collagenase activity was measured before and after activation of the latent enzyme by NaSCN treatment. Before activation, collagenase activity was present in the synovial fluids from 1 case of rheumatoid arthritis, 3 cases of degenerative joint disease, and 1 case of Behçet's syndrome. An excess of inhibitor was present in inactive synovial fluids. The incidence of collagenolytic activity markedly increased after treatment with NaSCN. When NaSCN-dependent collagenolytic activity was present, its value was of the same order of magnitude in all patients regardless of disease type. The diagnostic value of the finding of collagenase activity in synovial fluid, and the physiological meaning of the enzyme with reference to joint diseases, are discussed.
7057482 Ureteral stenosis secondary to retroperitoneal rheumatoid nodules. 1982 Jan A 57-year-old man with Felty's syndrome had flank pain as a result of ureteral obstruction and right hydronephrosis. The obstruction was due to retroperitoneal necrobiotic granulomas typical of rheumatoid nodules.
7423106 [Search for antilymphocytic antibodies in the serum of 67 children with juvenile chronic a 1980 Jul We sought the presence of lymphocytotoxic antibodies in the serum of 67 children with juvenile rheumatoid arthritis. We demonstrated in the serum of a large number of children (more than 50 %) antibodies reacting mainly with the cells not forming spontaneously rosettes with sheep red cells and/or all the mononuclear cells of the peripheral blood of normal subjects. These antibodies which are more active at 4 degrees C than at 20 degrees C are absorbable on red cells, and/or the platelet pool and present the characteristics of cold lymphocytotoxins. The presence of these antibodies was not correlated with either the clinical form of juvenile rheumatoid arthritis, nor with the duration of the course, nor with the treatment. Generally speaking, such antibodies are found during diseases where regulation of the immune response is modified.
560152 Fatal hepatic necrosis after halothane anesthesia in a boy with juvenile rheumatoid arthri 1977 Jul Hepatitis from halothane is usually diagnosed by excluding other possible causes. Whether preexisting hepatic damage, which can occur in certain autoimmune disorders, contraindicates the use of halothane has yet to be proven. The case of a 14-year-old boy with early-onset juvenile rheumatoid arthritis who developed fatal hepatic necrosis 13 days after halothane anesthesia is presented.
24832010 Rifamycin SV in the Treatment of Knee Synovitis. 1982 Oct Rifamycin SV, injected intraarticularly at dosages of 500 mg weekly, induced a complete removal of persistent knee effusions in 57 of 60 rheumatoid patients, and in all patients with effusions due to juvenile rheumatoid arthritis (three), ankylosing spondylitis (three), psoriatic arthritis (10), intermittent hydrarthrosis (two) and chondromatosis (two). One rheumatoid patient did not respond to treatment, and two dropped out because of local side effects. The number of infiltrations varied between three and 12, and was correlated with activity grade of local synovitis (P < .05). As of this writing, 50 out of 57 rheumatoid patients and 19 out of 20 belonging to the other groups have not had a relapse of effusions after 25 to 36 months and 12 to 20 months respectively. While the changes in the synovial fluid and membrane of the rheumatoid subjects, and the results obtained from experimental arthritis in guinea pigs, confirm the hypothesis that Rifamycin has a local antiinflammatory action in arthritic knee joints, they also suggest that this property alone of the drug is not entirely responsible for its therapeutic action.
6176246 Antibodies to and elevations of beta 2 microglobulin in the serum of ankylosing spondyliti 1982 Apr Antibodies to beta 2 microglobulin are found in systemic lupus erythematosus patients and are important in the lymphocytotoxic reactions of sera from such patients. In this study, beta 2 microglobulin antibodies were measured with the use of an enzyme-linked immunosorbent assay with purified beta 2 microglobulin antigen and peroxidase-labeled anti-human IgG or IgM. IgG antibodies to beta 2 microglobulin were found in 68% of 22 patients with ankylosing spondylitis. This incidence was higher than the 5% in 80 controls (P less than 0.01) and similar to the 71% incidence found in 35 patients with systemic lupus erythematosus. Eleven (27%) of 41 patients with rheumatoid arthritis had elevated levels of antibodies to beta 2 microglobulin (P less than 0.01). The mean antibody levels expressed in enzyme units were 0.125 for patients with ankylosing spondylitis, 0.157 for those with systemic lupus erythematosus, 0.101 for those with rheumatoid arthritis, and 0.067 for controls. IgM anti-beta 2 microglobulin was not significantly different from controls. A competitive binding assay with enzyme-labeled beta 2 microglobulin was used to determine serum beta 2 microglobulin. These values were also found to be elevated in 48% of patients in all 3 disease categories (P less than 0.01). Beta 2 microglobulin antibodies and serum beta 2 microglobulin did not correlate with each other, renal diseases or antinuclear antibodies in patients with systemic lupus erythematosus, with rheumatoid factor or severity of articular disease in patients with rheumatoid arthritis, or with peripheral arthritis or iritis in those with ankylosing spondylitis. Although antibodies to beta 2 microglobulin might reflect a general disturbance of immune regulation in patients with systemic lupus erythematosus, their presence in those with ankylosing spondylitis, a disease closely associated with a specific HLA allotype and not usually associated with formation of autoantibody, suggests that they might play a role in the pathogenesis of the latter disease.
6419599 Early experiences with auranofin in juvenile rheumatoid arthritis. 1983 Dec 30 Pharmacologic management of juvenile rheumatoid arthritis is only one of several modalities necessary for effective control. The stepping stones to proper management include a planned long-range program, physical therapy with swimming, good health habits, and consultation with other health professionals who are part of the management team. Pharmacologic therapy includes nonsteroidal anti-inflammatory drugs initially, occasionally corticosteroids, and slow-acting antirheumatic drugs, including injectable gold when therapeutic response is inadequate. Early experiences with oral gold are reported here. Auranofin (triethylphosphine gold) was administered to 21 patients with juvenile rheumatoid arthritis during a segment I, open ended, open-label, noncontrolled trial designed to establish safety and preliminary efficacy. Initial dosage was 0.1 mg/kg per day; incremental increases to 0.2 mg/kg per day were allowed (with usual increase to 0.15 mg/kg per day). Aspirin (80 mg/kg per day) or tolmetin (20 to 40 mg/kg per day), or naproxen (400 to 600 mg/m2 per day) were allowed as rapidly acting antiinflammatory agents. Stable measurable plasma concentrations of gold were attained in all patients during the study. More than half the patients sustained clinically significant improvement (greater than 25 percent) with regard to the number and severity of joints with swelling, pain on motion, and tenderness. In nine of the 19 patients, the total number of joints with active arthritis decreased by at least 25 percent. All articular disease indices measured indicated improvement of group mean changes between the initial and final visit. Eleven of 16 patients with an elevated erythrocyte sedimentation rate showed decreases of at least 25 percent. The group given higher dosages had a greater proportion of responders in regard to decreases in erythrocyte sedimentation rate (nine of 11 patients). Four of six patients whose serums contained rheumatoid factor showed decreases in the titers. Discontinuation of auranofin was necessary in two patients: one because of headache and one because of hematuria and anemia associated with a severe flare-up of polyarticular disease. The results from this trial reveal sufficient patient improvement to plan a double-blind trial of auranofin in children with juvenile rheumatoid arthritis.
3872119 A retrospective study of juvenile chronic arthritis. 1985 Feb During a 20 year period 214 patients had been admitted to a teaching hospital with a diagnosis of definite or possible juvenile chronic (rheumatoid) arthritis (JCA). Eighty-seven of these patients were reviewed clinically and were classified as having had JCA. Twelve of the 214 patients were later thought to have had rheumatic fever, while 12 had had an illness consistent with viral arthritis. There was a poor functional outcome in three subgroups of JCA: (i) seropositive polyarticular onset (ii) systemic onset, and (iii) pauciarticular onset, extending to polyarticular involvement. The prevalence of inflammatory eye disease was very low with no significant visual handicap detected in patients in this study.
1150312 Catabolism of human IgG in mice sensitized to various IgG fragments. Similarities to the c 1975 Apr Whole body elimination studies of human serum IgG have showm that C57Bl miceare tolerant to this protein at low concentrations. The present study demonstrates that tolerance to this protein may be broken by presensitization of the mouse with the pepsin-derived fragments of human IgG (F(ab)2 and pFc), in marked contrast to the papain-derived fragments (Fab and Fc). Sensitization with F(ab)2 fragments induced a distinctive elimination pattern of the intact protein which was analogousto that observed in non-sensitized mice injected with serum IgG isolated from patients with rheumatoid arthritis. Since, by circular dichroism studies, we have previouslyimplicated a structural anomaly at or near the hinge region of the 'rheumatoid' IgGmolecule, our observations are discussed in relationship to a possible immune aetiologyfor rheumatoid arthritis.
7455599 [HLA-B27 histocompatibility antigen in seronegative arthritis and idiopathic lumbar pain]. 1980 Jun The authors studied the distribution of 23 histocompatibility antigens of the loci A + B in 114 patients: 26 cases of serum negative rheumatoid arthritis, and 66 variants of serum negative arthritis and 22 cases of idiopathic lumbar pain. The distribution of antigens was compared with 71 individuals in good health. The groups of serum negative rheumatoid arthritis and idiopathic lumbar pain did not show significant differences compared with a control population. In the group of "variants" the frequency of B27 was increased (p < 0.001, p corrected < 0.02) especially in those who presented spinal involvement. In psoriatic spondylitis, there was no association between B27 and the spinal involvement (p < 0.01, corrected p < 0.23).
6334351 [Systematic research on enthesopathies in chronic rheumatism. Results and pathological sig 1984 Oct A routine investigation for rheumatic tendon lesions was conducted in 47 patients with an inflammatory spondylo-arthropathy and in 30 patients with rheumatoid arthritis. The incidence of tendon lesions (calcaneal and extra-calcaneal) differed very significantly (p less than 0.001) between the two groups (58.3% of patients with inflammatory spondylo-arthropathy had at least one tendon lesion, 6.6% of patients with rheumatoid arthritis). These results and data from the literature suggest that rheumatic tendon lesions are a characteristic feature of spondylo-arthropathy in the same way as sacro-iliitis, the absence of subcutaneous nodules, the absence of rheumatoid factor and the high incidence of histocompatibility antigen HLA B27. Together with this diagnostic value, there is also a histopathological value: inflammatory and ossifying tendinitis contrasts with the destructive synovitis of rheumatoid arthritis and can be considered to be a "sign" of inflammatory spondylo-arthropathy. Tendinitis and juxta-articular bone lesions in the limbs, so-called "peripheral" lesions, are similar to the vertebral lesions around the intervertebral disk and the posterior interapophyseal joints found in inflammatory spondylo-arthropathy. These lesions seem to be a common pathological feature, at least in part, with the polyarthropathies of childhood.
4845921 Diagnosis of "rheumatoid variants" ankylosing spondylitis, the arthritides of gastrointest 1974 Jun Four rheumatic diseases-ankylosing spondylitis, the arthritis accompanying ulcerative colitis or regional enteritis, psoriatic arthropathy, and Reiter's syndrome-formerly considered to be forms of rheumatoid arthritis, are now distinguished from that disorder and should be recognized by the physician as entities. These arthritides may be distinguished from each other by a number of clinical and radiographic characteristics, principally (1) the roentgenographic appearance of the spine when spondylitis is present, (2) the location of periosteal new bone formation, (3) the location of arthritis in the joints of the limbs, and (4) the presence of characteristic skin lesions.
833179 Isolated subcutaneous nodules (pseudorheumatoid). 1977 Jan Ten patients with isolated subcutaneous nodules histologically similar to rheumatoid nodules were studied. Because of the intense fibroblastic reaction in one such nodule, it was initially mistaken for a fibrosarcoma. The nodules tended to be multiple and recurrent, with eventual spontaneous regression, and they were not associated with any systemic illness. The etiology of these lesions is unclear but the possibility of subsequent development of systemic rheumatoid disease is remote.
834678 Psoriatic arthritis. 1977 Jan Despite having several modes of presentation, psoriatic arthritis usually can be readily distinguished from other forms of polyarthritis. Prominent features in all forms are a predilection for digital joints and occurrence of osteolysis and ankylosis. Rheumatoid factor is usually absent, and the prognosis appears to be better than that for rheumatoid arthritis. The relationship of HLA-B27 histocompatibility antigen to psoriatic arthritis is indefinite; presence of the antigen predisposes to spondylitis. For most patients, treatment directed at the psoriasis is adequate, especially if it is combined with the administration of nonsteroidal anti-inflammatory drugs.
6641044 Infection after total joint arthroplasty from distal extremity sepsis. 1983 Dec At the UCLA Medical Center in three patients treated for hematogenous infection after total joint arthroplasty, the source was apparently an infection in the extremities at a site distal to the joint arthroplasty. In a 72-year-old woman with rheumatoid arthritis infection developed in the right hip after total hip arthroplasty following a Staphylococcus aureus infection at the site of a left metatarsophalangeal arthroplasty. In a 64-year-old man with osteoarthritis the staphylococcal infection that developed after right total hip arthroplasty was seeded from a pyarthrosis of the right knee. In a 61-year-old woman with rheumatoid arthritis the sites of bilateral knee arthroplasties were seeded from a soft tissue infection of the left foot. These cases illustrate the potential for infection from local wound sepsis distal to joint arthroplasty. Such infections, particularly in patients with rheumatoid arthritis, should be treated aggressively to avoid seeding of the more proximal total joint arthroplasty site.
6768367 Gold therapy in the management of juvenile rheumatoid arthritis. 1980 Apr Gold therapy for 6 months was shown to be efficacious in reducing the severity of articular manifestations in 32 (63%) of 51 juvenile rheumatoid arthritis patients reviewed retrospectively. Similarly, reductions in the total number of involved joints were seen in 25 (49%) patients. Patients in whom a favorable response to therapy was noted had more severe joint involvement at the start of therapy than did nonresponders. In general, patients who responded experienced considerable improvement. Duration of disease prior to gold therapy initiation and disease onset type were not related to the probability of favorable response. Incidence of adverse side effects was low. Gold has recently been approved by the Food and Drug Administration for use in children.
6606398 Familial palindromic rheumatism: a possible association with HLA. 1983 Dec Palindromic rheumatism is very rare in children. The familial occurrence of the disease has been only briefly reported previously. A family is described here in which the mother and her 3 children suffered from typical palindromic rheumatism, which ran a benign course. All 4 members were seronegative and the HLA types of the children were identical. The HLA genotype of the mother was HLA A2, Cw4, Bw41, Bw6, DR5, MT2/Aw32, CX, Bw44, Bw4, DR1, MT1. HLA DR5 has previously been found to be associated with juvenile rheumatoid arthritis, while DR1 in Jews is significantly associated with adult-onset rheumatoid arthritis. DR5 was shared by the mother and her 3 children. The presence of the antigen DR5 in this sibship suggests that palindromic rheumatism may be a variant of juvenile rheumatoid arthritis with a relatively late onset and a more benign course. Tissue typing of patients with palindromic rheumatism may give a clue to prognosis. The patients' youth and the familial involvement, with identical HLA characteristics, are the outstanding features of this family.
6335854 The arthropathy of systemic sclerosis (scleroderma); comparison with mixed connective tiss 1983 Apr Arthritis in systemic sclerosis (PSS) can be prominent and an overlap with rheumatoid arthritis (RA) has sometimes been queried. We therefore analysed the pattern of joint involvement of hands and wrists in 34 patients (1 male) with PSS and compared it with that of 9 patients with mixed connective tissue disease (MCTD), a condition with distinct overlap features. Although MCTD patients were younger, disease duration was similar in both groups. Extra-articular radiological findings such as calcinosis, pulp atrophy and tuft resorption were present in over half the patients with PSS but were less frequent in MCTD. Marginal erosions occurred in over 50% and ulnar styloid erosions in 35% of the PSS patients. Erosions of the 1st CMC joint were seen in one-third of them and were unrelated to age. Erosions did not correlate with clinical synovitis, the presence of rheumatoid factor which was present in 26% of PSS patients or the presence of anti-centromere or anti-Scl-70 antibodies. Erosions in MCTD patients occurred frequently and were more destructive and rapidly progressive. Correlation between erosions, rheumatoid factor and clinical arthritis was high. We conclude that erosions in PSS are frequent. Their pattern is varied but usually discrete and seldom destructive. They are not related to arthritis or serological abnormalities and may be due to several mechanisms aside from synovitis. In contrast, erosions in MCTD are more frequently destructive and related to arthritis and rheumatoid factor, suggesting a true overlap.
