3335557 Distal femoral varus osteotomy. 1988 Jan The results of twenty-three distal femoral varus osteotomies (in twenty-one patients) that were performed between 1977 and 1984 were evaluated. Fifteen osteotomies were done for osteoarthritis; three, for post-traumatic arthritis or deformity; three, for rheumatoid arthritis; and two, for renal osteodystrophy. The median age of the patients was fifty-six years (range, nineteen to seventy years). The length of follow-up averaged four years (range, two to nine years). The average tibiofemoral angle preoperatively was 18 degrees of valgus, which was corrected postoperatively to an average of 2 degrees of valgus. At follow-up, nineteen (83 per cent) of the twenty-three knees were rated as good or excellent according to The Hospital for Special Surgery knee score, which had improved from an average of 65 points preoperatively to 86 points post-operatively. Of the fifteen patients who had osteoarthritis (93 per cent), all but one had a good or excellent result. Most patients had no substantial improvement in the range of motion of the knee as a result of the operation. Eighty-six per cent of the patients expressed satisfaction with the outcome. We concluded that varus osteotomy of the distal part of the femur is a reliable and effective surgical procedure for the treatment of gonarthrosis associated with valgus deformity due to osteoarthritis or trauma. We do not recommend its use in patients who have rheumatoid arthritis or in those who have inadequate motion of the knee before the operation.
2963130 Impaired in vivo and in vitro antibody responses to bacteriophage phi X 174 in juvenile rh 1987 Oct Immunologic abnormalities described in juvenile rheumatoid arthritis (JRA) have been largely confined to mitogen or antigen driven proliferation assays. We studied antigen specific antibody production using the neoantigen bacteriophage phi X 174 in vivo and in vitro; defective responses were found in all 8 patients with JRA studied. These could not be attributed to circulating anti-T cell antibodies, but may relate to lymphocyte subset abnormalities found by 2 color analyses. These immunologic aberrations may play a direct role in the pathogenesis of JRA or, alternatively, may be a secondary event.
1799500 [A case of Fahr's disease associated with juvenile rheumatoid arthritis]. 1991 Oct We studied a case of Fahr's disease type idiopathic intracerebral calcification (Fahr's disease) associated with juvenile rheumatoid arthritis. The patient was a 15-year-old male with a chief complaint of gait disturbance. His family members had no similar signs and symptoms. His parents had no consanguinity. He was born with the normal perinatal course at 1967. He had repeated episodes of convulsive attacks during fever elevation from 2 years and 8 months to 9 years of age. Morning stiffness of bilateral hands, and pernio in the auricles, fingers, planta, and toes had occurred in every winter, since 6 years old. Swelling and pain of the bilateral knee and foot joints appeared, making ambulation difficult in 1983 (15 years old), and the patient was admitted to our hospital in July, the same year. On admission, congenital anomalies such as epicanthus and high-arched palate were noted, and swelling, deformation and contracture of limb joints, and Raynaud phenomenon were shown. His ocular fundus showed no arteriosclerotic change. He didn't have Albright's sign. Mild mental retardation and bilateral pyramidal tract signs were noted, but extrapyramidal tract and cerebellar signs, and sensory disturbance were absent. Laboratory findings exhibited markedly elevated ESR, positive CRP, RA, and antinuclear antibody. The levels of serum Ca, P, alkaline phosphatase and parathyroid hormone were normal. Peripheral blood study showed microcytic and hypochromic anemia. Anti-DNA antibody was negative. Ellsworth-Howard test was positive. Elevated antibody titer to toxoplasma, rubella virus, herpes simplex virus and cytomegalovirus were not proven. He had no chromosomal change.(ABSTRACT TRUNCATED AT 250 WORDS)
3534260 Longterm auranofin therapy in patients with juvenile rheumatoid arthritis. 1986 Aug Auranofin (AF, Ridaura) was administered to 23 children with juvenile rheumatoid arthritis during a prospective, open labelled, noncontrolled trial designed to establish longterm safety and preliminary efficacy. Dosages of AF were up to 0.2 mg/kg/day, with either aspirin (60-80 mg/kg/day), naproxen (400-600 mg/m2/day), or tolmetin sodium (20-40 mg/kg/day) serving as the concurrent nonsteroidal antiinflammatory drug. Nearly all patients showed an initial favorable response, however tachyphylaxis occurred in one-third (mean duration of therapy prior to the development of inefficacy = 22.6 mo). Clinical remission was observed in 6 patients an average of 15 months after enrollment. The drug appears to be safe for extended periods; 7 children are continuing AF at the present time with a mean duration of therapy of 4.25 years (maximum followup = 4.6 years).
2805555 Children with juvenile rheumatoid arthritis at school. Functional problems, participation 1989 Nov Parents of 135 children with juvenile rheumatoid arthritis (JRA) completed a mailed questionnaire about problems at school. Writing was the most frequently reported difficulty, with hand involvement causing more problems than decreased mobility. Compared to children with pauciarticular JRA, those with polyarticular or systemic JRA were significantly more likely to miss school, experience problems, participate less in physical education, have an Individualized Educational Plan (IEP) developed, and receive related services. Only 39 parents had heard of PL 94-142, and only 21 of those could define the federal law. Twenty children had an IEP within the previous two years. Possible deficiencies in the implementation of PL 94-142 were discovered. This study demonstrates that the treatment of children with JRA should include efforts to: 1) identify and remediate potential performance limitations before they become problematic at school; 2) communicate this information to parents and school personnel; 3) and improve parents' awareness and understanding of PL 94-142.
2685294 Antibodies to iris and retina detected in sera from patients with juvenile rheumatoid arth 1989 Aug Sera from 12 patients with juvenile rheumatoid arthritis (JRA) with active iridocyclitis were incubated with frozen, sectioned, whole human eye tissue. Antibodies were detected using fluorescein conjugated goat F(ab')2 antibody to human IgG by immunofluorescent microscopy. Immunofluorescence was determined on tissue from the iris, retina, and 3 portions of the ciliary body. Sera of patients with JRA with iridocyclitis were compared to sera from patients with JRA with and without antinuclear antibodies (ANA) and healthy children. An increased frequency of antibody to the human iris was seen with sera of patients with JRA with iridocyclitis compared to healthy children's sera. A higher frequency of antibody was also noted to human retina in sera of patients with JRA with iridocyclitis compared to patients without ANA and healthy children. No increased frequency of antibody was detected to ciliary body. Sera of 7 patients with JRA with iridocyclitis were also compared during a time of inactive eye disease to a time of active disease. No difference in binding to eye tissue was detected at times of inactive disease compared to controls. Our results demonstrate the presence of antibody to iris and retina by immunofluorescence in the sera of patients with JRA with iridocyclitis.
2242072 Rescue of interleukin-1 activity by leucovorin following inhibition by methotrexate in a m 1990 Nov We have recently shown that methotrexate (MTX) inhibits interleukin-1 (IL-1) activity in vitro. This effect may play an important role in the rapid antiinflammatory action of MTX in rheumatoid arthritis. In the present study, we showed that the inhibition of IL-1 activity in vitro by MTX is dependent on folate pathways since, after the addition of leucovorin, the inhibitory effect of MTX was abolished. These findings may shed more light on the mechanism of action of MTX in rheumatoid arthritis. They also point to the fact that some IL-1 activities may be dependent on intracellular folate pathways.
3288326 Joint infection, with consideration of underlying disease and sources of bacteremia in hem 1988 May Joint infection commonly results from hematogenous spread of infection from a distant site. Pre-existing joint disease increases the risk of joint infection during bacteremia. Most patients present with pain, swelling, heat, and limitation of motion of the affected joint, often with fever, but presentation may be atypical, especially in patients with rheumatoid arthritis, systemic corticosteroid therapy, or infected prosthetic joints. Diagnosis is best made by analysis and culture of synovial fluid. The infecting microorganism often provides a clue to remote infection or underlying disease, which may require special attention. Therapy consists of high-dose parenteral antibiotics and adequate drainage. Outcome depends on early diagnosis and appropriate therapy.
3737913 Infantile-onset multisystem inflammatory disease: radiologic findings. 1986 Sep Infantile-onset multisystem inflammatory disease (IOMID) is a newly recognized disease that is similar to systemic-onset juvenile rheumatoid arthritis (JRA). The clinical symptoms of IOMID include rash, fever, lymphadenopathy, chronic meningitis, uveitis, and a distinct arthropathic condition. Skeletal involvement is surprisingly constant. The long bones become short, bowed, and widened. The metaphyses flare and simulate rickets. Grotesque epiphyses appear fragmented early in the course of the disease but are gradually incorporated into the widened shafts. We observed these and other radiologic findings in the four cases described in the present study. The findings are distinctive and allow for a specific diagnosis.
3947407 Homologous type II collagen induces chronic and progressive arthritis in mice. 1986 Jan Native mouse type II collagen was used for immunization of DBA/1 mice. Arthritis developed exclusively in male animals and was characterized by a variable and delayed onset, a slow and progressive development, and frequent exacerbations of disease in several joints including those that were previously affected. Titers of anti-type II collagen autoantibodies were found not to correlate well with arthritis development. It appears that experimental arthritis induced with homologous type II collagen resembles rheumatoid arthritis in humans, both in certain clinical features and in the lack of correspondence between anti-type II collagen autoantibody titers and disease symptoms.
1765488 [Dermatological manifestations of Sjögren's syndrome]. 1991 Dec In primary Sjögren's syndrome, various cutaneous manifestations may become apparent: annular erythema or eruptions reminiscent of erythema multiforme, lichen planus or erythema nodosum (dermo-panniculitis), chilblain-like erythema, purpura, cheilitis, and xerosis, are some of them. In the clinical diagnosis, the following laboratory tests are of value: Schirmer test, rose bengal test, fluorescence staining techniques, gum test, sialography, sialoscintigraphy, lip biopsy. In some cases, dryness can be absent though the above-mentioned skin manifestations are observed. Mothers with Sjögren's syndrome can deliver babies with neonatal lupus erythematosus. Serological testing almost always reveals anti-Ro/SSA-autoantibody and the more specific anti-La/SSB in the sera of patients. The sensitivity of detection can be enhanced by using the immunoblotting technique and the two-dimensional immunoblotting method. In some cases, a new antibody against carbonic anhydrase has been detected.
1914422 Multicentric reticulohistiocytosis associated with subclinical Sjögren's syndrome. 1991 Jun A case of multicentric reticulohistiocytosis in a 60-year-old Japanese woman associated with subclinical Sjögren's syndrome is presented. The clinical features along with the light microscopic studies are commented. Partial improvement of the skin lesions and tendon sheath swelling was achieved after treatment with cyclophosphamide but the patient's general condition remained unchanged. Taking the rarity of multicentric reticulohistiocytosis into account, coexistence of these two conditions in the present and previously reported cases suggests that an autoimmune mechanism may play a part in the pathogenesis of multicentric reticulohistiocytosis.
2575337 The management of 138 psoriatic arthritic patients. 1989 Clinical experience obtained in the management of 138 patients of psoriatic arthritis is reported. The correct recognition of arthritic subtype (according to Moll and Wright classification) always resulted essentially in the choice of the therapy. Our programme included rehabilitative, pharmacologic and surgical approaches. Our data suggest that psoriatic arthritis is a mild articular disease when compared to other affections such as rheumatoid arthritis or ankylosing spondylitis. Notwithstanding an accurate therapeutical programme, it is necessary to control atypical cases which not infrequently can occur.
3051098 Septic arthritis. 1988 Nov Infectious arthritis is a commonly encountered clinical problem which may result from articular contamination by a wide variety of organisms. Involvement of an articulation may occur by one of four mechanisms: hematogenous spread, spread from a contiguous source of infection, direct implantation, or postoperative contamination. Distribution is typically monoarticular with a swollen, erythematous, and painful joint. The radiographic differential diagnosis includes limited rheumatoid arthritis, gout, synovial osteochondromatosis, and pigmented villonodular synovitis. In order to prevent complications, including growth disturbances, articular destruction with ankylosis, osteomyelitis, or soft tissue extension, early diagnostic arthrocentesis is important. Radiographic abnormalities, which include soft tissue swelling, joint space loss, periarticular osteopenia, and central or marginal osseous erosions, may be delayed following clinical onset of infection. Advanced imaging techniques such as scintigraphy, CT, or MRI may allow accurate diagnosis of the infectious process at an earlier stage.
1958098 Septic arthritis complicating hip osteoarthritis. 1991 Oct Four patients with osteoarthritis of the hip, who developed septic arthritis of the affected joint, are reported. The septic arthritis developed insidiously and was diagnosed with difficulty. One patient died, two required subsequent joint excision, and one arthrodesis despite antibiotics. The presence of a recognised predisposing factor to septic arthritis, such as rheumatoid arthritis or a surgically replaced joint, can provide a diagnostic pointer. These cases suggest that osteoarthritis, similarly, is a predisposing factor. It is concluded that joint sepsis should be considered if a patient with osteoarthritis develops new symptoms from a single joint with associated systemic features.
3044671 Diagnostic significance of salivary levels of beta 2-microglobulin in Sjögren's syndrome. 1988 Mar To evaluate the diagnostic significance of salivary beta 2m in Sjögren's syndrome we measured salivary beta 2m levels in 19 patients with primary sicca syndrome (PSS), 15 with secondary Sjögren's syndrome (SSS) and compared the results with 20 normal healthy persons. We showed that beta 2m is specifically excreted in the saliva, because in normal saliva the concentration of beta 2m was unrelated to IgA levels. Also in normals, there was no relationship between serum and saliva concentrations of beta 2m. The mean saliva levels of beta 2m were increased in PSS (1.13 +/- 0.58) and SSS (1.39 +/- 0.69) compared with the levels in normals (0.53 +/- 0.22). The determination of beta 2m in the saliva can therefore be used as a noninvasive measurement for the confirmation of the diagnosis Sjögren's syndrome.
2758490 [The incidence of antibodies against collagen in patients with juvenile chronic arthritis] 1989 Jun Using the ELISA method, the authors assessed titres of antibodies to collagen type I, II and III in serum of patients with juvenile chronic arthritis (JCA). The results were compared with antibody titres in patients with rheumatoid arthritis (RA). Elevated antibody titres to all collagen types were found, as compared with age-matched controls. The mean titres in patients with RA were higher than in the group with JCA. Investigation of a correlation between the collagen antibody titres and values of the sedimentation rate after one hour revealed a statistical relationship only in collagen type II in patients with RA.
2787058 [A case of antigranulocyte antibody positive Felty's syndrome and its efficacy of plasmaph 1989 Feb The patient is a 44-year-old female case of RA having a history of 10 years after onset, being admitted due to fever accompanied by granulocytopenia. By laboratory findings, WBC was 1,900/mm3, CRP 5+, RA 2+, RAHA 80 times, LE cells positive, antinuclear antibody strongly positive, granulocyte-specific antinuclear antibodies positive, and granulocyte specific cytotoxicity test strongly positive. Examination of bone marrow smears revealed, the cell numbers tended to decrease in the neutrophil maturity phase. The case was diagnosed as Felty's syndrome because of the obvious splenomegaly and leukopenia. Administration of 30 mg/day of prednisolone was not sufficient in effect, and plasmapheresis was conducted concomitantly. As a result, the granulocyte count increased and the granulocyte cytotoxicity titer was lowered. It is hence suggested that the antigranulocyte antibodies are responsible for the mechanism of granulocytopenia in this case, and the possibility of promotion of destruction in the periphery was inferred, and it is accordingly considered useful to combine administration of small dose of adrenocortical steroid preparation with plasmapheresis for the treatment of this disease.
3070728 Rheumatoid factors in leprosy and parasitic diseases. 1988 Rheumatoid factors (RFs) occur with higher frequency and in higher titres in multibacillary forms of leprosy and several parasitic diseases than in healthy controls. The selection of controls is essential in studies of this kind. They should be individuals without signs of the disease under study living under similar socioeconomic conditions as the patients in the endemic country. In three studies where this matter was considered, RFs in lepromatous leprosy and Chagas' disease reacted more strongly with rabbit than human IgG, a feature generally considered to be quite restricted to rheumatoid arthritis. RFs interfere in various test systems, particularly in inducing false positive reactions for specific IgM antibodies in parasitic and other infectious diseases. Model experiments in rats, in vitro culture studies, and observations in humans indicate that RFs may have a protective role in trypanosome infections, malaria and schistosomiasis respectively.
2203591 Anti-Ro (SSA)/La (SSB) antibodies and Sjögren's syndrome. 1990 Mar Antibodies to Ro (SSA) and La (SSB) cellular ribonucleoprotein complexes are found in the circulation of patients with Sjögren's syndrome (SS), mainly in those with the primary form of the syndrome. Their presence is associated with long disease duration, earlier disease onset, parotid gland enlargement, systemic manifestations and also with hypergammaglobulinemia, rheumatoid factors and monoclonal type II cryoglobulins. While anti-Ro (SSA) antibodies are not specific for SS, anti-La (SSB) antibodies seem to be specific. Studies of HLA class II molecules in Ss patients with and without these antibodies have shown that their production is under genetic control. Finally, there is no conclusive evidence relating pathogenetically these autoantibodies to tissue destruction in SS.
