499259 Rheumatoid arthritis during the first year of life. A case report and review of the litera 1979 Oct A 20-week-old female, first examined at 14 weeks of age for daily "spiking" fever and skin rash, subsequently developed signs of rheumatoid arthritis. The onset of rheumatoid arthritis during the first weeks of life is rare and its diagnosis may be difficult. It seems that onset during the later months of the first year is more frequently encountered. A review of the relevant publications in English disclosed that onset during first year was noticed in 1.02 percent of the patients, while in a study from Germany 6 to 9.9 percent of cases started during their first year.
686861 Juvenile rheumatoid arthritis with cardiac tamponade. 1978 Jun A 4-year-old girl with seronegative systemic juvenile rheumatoid arthritis developed acute cardiac tamponade. Pericardiocentesis and systemic corticosteroids resulted in complete recovery of the pericardial involvement. This was followed by complete remission of rheumatoid disease.
4859474 Rheumatoid rosette in juvenile rheumatoid arthritis. 1974 Jun The rheumatoid rosette test was performed in 159 children. Positive results were found more frequently in juvenile rheumatoid arthritis when more than four joints were involved. It is not to be considered as a diagnostic test since `false positive' tests occur in other diseases. The immunological significance of the rosette test is discussed.
90385 [A case of pulmonary hemosiderosis associated with rhumatoid arthritis with LE cells (auth 1979 Jun 8 In a three and a half old girl, we have noticed the apparition: first, of on idiopathic pulmonary hemosiderosis; then, five months later, of a rheumatoid arthritis with LE cells and antinuclear antibodies of very difficult detection. The meaning of this articular involvement is discussed: rheumatoid arthritis with LE cells, or rheumatoid arthritis marking the beginning of a systemic lupud erythematosus. The literature concerning the association of an hemosiderosis and a connectivite is reviewed.
660358 Anemia in patients with juvenile rheumatoid arthritis. 1978 Jun Patients with juvenile rheumatoid arthritis may have an anemia attributable to the chronic disease, to iron deficiency, or to a combination of the two. The contribution of iron deficiency is often difficult to determine by routine laboratory studies. We studied 51 patients with pauciarticular and polyarticular juvenile rheumatoid arthritis with red blood cell counts, indices, free erythrocyte protoporphyrin, and serum ferritin. Fifteen of the 18 who were anemic were restudied after a 3 to 6-month period of iron therapy. Thirteen of the 15 responded by these criteria: a rise in hemoglobin of 1.0 gm/dl or more and an increase in mean corpuscular volume of 3 fl or more; in 11 of these 13, hemoglobin values returned to the normal range for age. These findings indicate that iron deficiency can be a major component of the anemia that is commonly found in patients with active juvenile rheumatoid arthritis.
6978718 Use of monoclonal antibodies to analyze peripheral blood and salivary gland lymphocyte sub 1982 Apr Using monoclonal antibodies to cell surface antigens, we studied lymphocyte subsets in 15 patients with primary Sjögren's syndrome. The absolute number of OKT8-positive cells (reactive with T suppressor/cytotoxic cells) was significantly decreased in such patients (353 +/- 186/mm3) compared to age-matched controls (631 +/- 150/mm3) (P less than 0.001). The number of OKT4-positive cells (reactive with T helper/inducer cells) was comparable in both groups (932 +/- 588/mm3 versus 1.073 +/- 290/mm3). The ratio of OKT4/OKT8-reactive peripheral blood lymphocytes was increased (greater than 2.4) in 67% of these patients and ranged from 1.0 to 6.4 (normal = 1.8 +/- 0.3). OKT4-positive cells were the predominant subset in lip biopsy specimens stained with immunofluorescence or immunoperoxidase techniques; the OKT4/OKT8 ratio exceeded 3.0 in all 5 patients examined. In 1 patient with pseudolymphoma, a lymph node biopsy specimen contained 80% T cells with an OKT4/OKT8 ratio of 3.2. Thus, OKT4-positive cells predominated in the peripheral blood lymphocytes as well as in sites of inflammation in primary Sjögren's syndrome. The decreased number of OKT8-positive cells in primary Sjögren's syndrome was probably not caused by circulating autoantibody, since patients' sera did not react with normal OKT8-positive cells. Functional studies using pokeweed mitogen demonstrated that T helper cell activity for immunoglobulin synthesis was contained in the OKT4-positive subset in both normal and patients' peripheral blood lymphocytes. Removal of OKT8-positive cells by complement-mediated lysis did not lead to increased immunoglobulin synthesis or production of rheumatoid factor. The identification of peripheral blood lymphocyte subsets by use of monoclonal antibodies and the relationship of these subsets to tissue infiltrates and autoantibody production provide further insight into the pathogenesis of primary Sjögren's syndrome.
7215753 Lymphocytes in juvenile rheumatoid arthritis (JRA) studied by means of electron and scanni 1980 When searching for timely diagnostic criteria of juvenile rheumatoid arthritis we also paid attention to lymphocytes. We found the elimination of hyaloplasma of lymphocytes is one of the criteria of approaching outbreak of the disease.
7129266 Juvenile rheumatoid arthritis of the foot. 1982 Jul Rheumatoid arthritis occurring in children under 16 years of age is defined as juvenile rheumatoid arthritis. It is more common in females and the peak incidence is between 1 and 3 years of age. It can present in different forms. Mono- and pauciarticular type is complicated by iridocyclitis in 20%. Growth disturbances are common. Any conceivable combination of foot deformities can occur. Some of the secondary deformities can be prevented with conservative care. Principals of soft tissue and bony surgery have been outlined.
1258635 Hypohistidinemia in juvenile rheumatoid arthritis. 1976 Mar The mean level of plasma histidine in 86 children with rheumatoid arthritis was found to be significantly lower in comparison with that of controls. The possible influence of various drugs on the plasma histidine concentration is discussed.
881695 Serum immunoglobulin and complement interrelationships in juvenile rheumatoid arthritis. 1977 Summer Patients with juvenile rheumatoid arthritis (JRA) were compared with a matched control group for the presence and levels of IgG, IgM, IgA, IgE, IgD, C3, C4, and rheumatoid factor. In the majority of patients (86.1 to 94.4%) the distributions fell within the normal ranges of the control group. In JRA, older age appears to have a significant relationship for increased IgE levels. Levels of IgE and IgD do not appear to be related to the presence or activity of JRA. Significantly elevated levels of IgG, IgA, and C4 were found in active disease while elevated IgM levels are characteristic of the disease itself.
6461464 Multiple dislocations of the cervical spine in a patient with juvenile rheumatoid arthriti 1982 Jan Both Down's syndrome and juvenile rheumatoid arthritis can cause instability of the cervical spine. Patients with Down's syndrome usually have instability of the atlantoaxial joint. With juvenile rheumatoid arthritis, cervical instability is a manifestation of a more generalized process involving ligamentous laxity, posterior facet ankylosis, and growth disturbances of the vertebral bodies. When the two syndromes occur in the same patient, the potential exists for serious cervical instability. In the 14-year-old girl reported here, the two conditions coexisted, and more severe cervical spine involvement occurred than was originally anticipated. Prior awareness of the combined effects of Down's syndrome and juvenile rheumatoid arthritis on the stability of the cervical spine should be useful in the management of future cases.
326961 Radioimmunoassay of IgG and IgM rheumatoid factors reacting with human IgG. 1977 Jul Although IgG rheumatoid factor may play a central role in the pathogenesis of rheumatoid arthritis, previously there have been no precise methods for its specific measurement in serum and synovial fluid. This paper describes a solid phase radioimmunoassay for the independent quantification of IgM and IgG rheumatoid factor reacting with the Fc fragment of human IgG. As measured by this assay, serum IgG rheumatoid factor levels differed significantly between patients with seropositive and seronegative rheumatoid arthritis and normal control subjects. In addition, several sera and joint fluids from patients with seropositive rheumatoid arthritis, even without vasculitis, were shown by gel chromatography to have acid-dissociable complexes of IgG rheumatoid factor suggestive of IgG-IgG dimer or trimer formation.
4578296 Abnormalities in the distribution of serum immunoglobulin concentrations in juvenile rheum 1973 Aug Concentrations of serum IgG. IgA, and IgM were determined in 200 patients with juvenile rheumatoid arthritis. The relative frequency distribution of IgG and IgM approached that of a log-normal curve; however, there was marked skewing of the distribution of the serum concentrations of IgA. The prevalence of selective IgA deficiency was 4%. In order to permit further intragroup comparisons, the serum immunoglobulin concentrations were standardized by comparison to a sex-age matched control group. By this process it was found that there was concordance of the serum levels of IgG with IgA, and IgG with IgM. The standardized concentrations of IgA and IgM were less in females than males. The aberration in distribution of serum IgA concentrations found in this study, and the relative inability of females to respond to their disease by increasing specific serum immunoglobulin levels, add further data supporting the concept of immunodeficiency in the pathogenesis of juvenile rheumatoid arthritis.
6974234 Juvenile rheumatoid arthritis in children with diabetes mellitus. 1981 Oct Seven children with insulin-dependent diabetes mellitus were found to have juvenile rheumatoid arthritis; six of these children had the polyarticular form of the disease. All six had positive serology (rheumatoid factor and/or antinuclear antibody) and clinical or serologic evidence of autoimmune diseases usually ascribed to the thyrogastric cluster. Five expressed HLA antigens associated with increased risk for both diabetes and rheumatoid arthritis in adults. Evidence of B cell hyperactivity and impaired T cell response was found in some, but immunoregulatory function was normal in all. The association of these two diseases may be the result of factors other than chance alone, and may be more common than previously suspected.
6873109 Progressive pseudorheumatoid arthritis of childhood (PPAC). A hereditary disorder simulati 1983 Mar Five patients are described with a hereditary arthropathy affecting major and minor joints. The main features of this progressive connective tissue disorder are restricted joint mobility, osseous swelling of the interphalangeal and other joints, and platyspondyly. The condition is commonly misdiagnosed as "chronic juvenile polyarthritis with Scheuermann disease". It differs from the rheumatoid-factor-negative polyarticular form of rheumatoid arthritis and other rheumatoid spondylarthropathies by the absence of arthritic and other inflammatory changes, radiographically by the absence of destructive and the presence of dysplastic bone changes. The disorder does not seem to respond to the usual forms of antirheumatoid treatment. Histological studies showed a peculiar, nest-like clustering of chondrocytes in the resting and growth cartilage suggesting that pathogenetically this is a primary disorder of the articular cartilage.
6208913 Sjögren's syndrome. Influence of multiple HLA-D region alloantigens on clinical and serol 1984 Nov The relationships of HLA-DR and the newer DS (second D locus) B cell alloantigens (MB and MT) to the clinical and serologic expression of primary and secondary forms of Sjögren's syndrome (SS) were examined in 102 patients (86 whites and 16 blacks). Although HLA-DR3 was significantly increased in whites (25 of 50, 50%) and blacks (4 of 5, 80%) with primary SS compared with race-matched normal controls, it was not appreciably elevated in those with systemic lupus erythematosus (SLE)-SS, rheumatoid arthritis (RA)-SS, or connective tissue disease-SS. The MT2 specificity, however, was more strongly associated with primary SS (86% of whites and 100% of blacks) and also with SLE-SS and RA-SS compared with race-matched normal controls. Furthermore, MT2 was significantly increased in SLE-SS and RA-SS when compared with non-sicca SLE and RA controls. Although primary and secondary SS were most strongly associated with this DS specificity (MT2), the anti-Ro (SS-A) and anti-La (SS-B) antibody responses were more closely allied to DR antigens. HLA-DR3 was increased in anti-Ro positive patients, both whites and blacks, with primary SS (74%) and in total anti-Ro positive subjects (54%) compared with their anti-Ro negative counterparts (38% and 31%, respectively). Among DR3 negative patients, HLA-DR2 correlated with anti-Ro in both primary SS (83%) and in the total SS group (58%). Thus, 96% of Ro antibody positive patients with primary SS had DR3 and/or DR2, as did 80% of anti-Ro positive subjects in all categories.(ABSTRACT TRUNCATED AT 250 WORDS)
7383409 [Juvenile rheumatoid arthritis appearing after hepatitis. Causal or casual relationship]. 1980 May 26 High fever, spleen and lymph node enlargement, and joint pains that assumed the character of rheumatoid arthritis in the ensuing months were noted after a viral hepatitis episode in a 21-year-old woman. Serious anaemia and myocarditis also appeared when the picture was at its worst. A lymphoma was suspected, and the spleen and some abdominal lymph nodes were removed. These displayed signs of intense follicular reaction unaccompanied by atypia. The possibility that juvenile rheumatoid arthritis may be triggered by hepatitis is examined.
380236 [Isolation of bacterial L forms from the joint fluid in rheumatoid arthritis in children]. 1979 Jun In the bacteriological study of intra-articular fluid in 22 children with rheumatoid arthritis the L-forms were isolated in 11. Of these, 7 had not been treated with preparations of the penicillin series. The complete isolation of the focus of inflammation from the environment and the presence of the L-forms of bacteria in the children who had not been treated with preparations of the penicillin series gave us grounds for conclusions on the etiological and pathological significance of the L-forms of streptococci in rheumatoid arthritis.
1211694 [Juvenile rheumatoid arthritis: Characterisation of its clinical variations (author's tran 1975 Nov This study of 42 patients affected with juvenile rheumatoid arthritis (JRA), in which two defined clinical forms are established: febrile and non-febrile. Patients with JRA with high temperatures for more than 3 weeks, are included in the febrile form when any other cause for the fever can be excluded. In this study, 18 patients had febrile JRA, and the main clinical features were the higher number of joints involved, the presence of rash and the higher incidence of increase in size of the liver and/or spleen. Laboratory studies in cases affected by febrile JRA are characterized by higher frequency of high white blood count (p less than 0.001) and low frequency of rheumatoid factors (0.025 less than p less than 0.05) and antinuclear antibodies (0.001 less than p less than 0.005). Another finding is the incidence of microvasculitis: 31% in a group of 38 patients with JRA. Although microvasculitis is more frequent in the form of JRA without fever. it is a statistically significant characteristic of both forms of JRA described.
725041 Carpal length in children--a useful measurement in the diagnosis of rheumatoid arthritis a 1978 Dec The distance between the midpoint of the distal radial epiphyseal growth plate and the proximal end of the third metacarpal offers a useful measure for determining wrist size. Standards of this distance as compared to intermetacarpal width and second metacarpal length are presented. These measures (or ratios) should be useful in evaluating patients with juvenile rheumatoid arthritis and a number of congenital malformation syndromes, particularly when the carpals are still not fully ossified. Shortening of the carpus occurs in multiple epiphyseal dysplasia, the otopalatodigital syndromes, Turner syndrome, arthrogryposis, and in juvenile rheumatoid arthritis. A relatively large carpus is present in achondroplasia.
