| 1083785 | Cell-mediated immunity in the rheumatoid diseases. I. Skin testing and mitogenic responses | 1975 Dec | Cellular immunity has been investigated in patients with various kinds of sero-negative arthritis. The incidence of cutaneous response to recall antigen streptokinase-streptodornase (SK-SD), and the ability to mount a primary cutaneous response to dinitrochlorobenzene (DNCB) have been examined in patients with ankylosing spondylitis and psoriatic arthritis. The results were not significantly different from normal. In vitro lymphocyte transformation in the presence of phytohaemagglutinin (PHA), concanavalin A (Con A), and pokeweed mitogen (PWM) has been measured using peripheral blood lymphocytes from patients with ankylosing spondylitis, psoriatic arthritis and Reiter's disease. In comparison with a control group, significantly reduced responses were found to a low dose of PHA in the ankylosing spondylitis and Reiter disease patients. Significant increase in response occurred to a high dose of PHA, in patients with psoriatic arthritis and Reiter's disease, and to PWM in Reiter's disease patients. The in vitro results in the ankylosing spondylitis, psoriatic arthritis and Reiter's disease patients suggest some abnormality in the T-cell population in sero-negative arthritis. | |
| 6967133 | Interstitial nephritis in a patient with atypical Sjögren's syndrome. | 1980 Jun 2 | A patient was observed with interstitial nephritis which resulted in renal tubular acidosis (distal type), tubular proteinuria and defective urinary concentrating ability in the absence of edema, elevated arterial blood pressure, glomerular proteinuria or abnormal urinary sediment. The presence of interstitial nephritis was established by renal biopsy which showed dense infiltrates in the interstitium, interstitial fibrosis and thickening and splitting of the pericapillary basal membranes. Immunofluorescence was non contributory. Extrarenal symptoms were discrete (arthralgia of both hands, Raynaud's syndrome upon cold exposure). Mixed connective tissue disease (MCTD) was suspected because of a positive ANF test (speckled pattern), which was completely abolished by ribonuclease pretreatment. However, in hemagglutination tests, no antibodies against ribonuclear protein (ENA) could be demonstrated. The diagnosis of Sjögren's syndrome was established by demonstration of antibodies against SSA and SSB antigens. The observation suggests that in patients with interstitial nephritis the diagnosis of Sjörgren's syndrome must be considered even if extrarenal symptoms of Sjögren's disease are minimal or lacking. The diagnosis can be established with recent serological techniques. | |
| 961705 | Splenosis: autotransplantation of splenic tissue. | 1976 Sep | Splenosis is the autotransplantation of splenic tissue that usually follows traumatic rupture of the spleen. Generally, the splenic implants are numerous and are located within the peritoneal cavity; however, extra-abdominal splenosis does occur. The implants are rarely clinically significant and are incidental findings at autopsy or at abdominal operation, unrelated to and distant from the splenic trauma and splenectomy. Splenic implants retain their ability to function, and recurrence of a hematologic disease for which the spleen was previously removed should alter the clinician to the possibility of splenosis. The differential diagnosis includes accessory spleens, endometriosis, hemangiomas and metastatic cancer. We report three cases, two of which represent unusual complications of splenosis: a twisted pedicle of a splenic implant, which apparently caused abdominal pain, and recurrent Felty's syndrome associated with splenosis and an accessory spleen. | |
| 1215941 | [Lymphoproliferative diseases and paraproteinemias in Sjogren's syndrome]. | 1975 Nov 8 | Out of 8 cases of Sjörgren's syndrome observed by the authors between 1964 and 1974, 5 presented wit clinically as well as theoretically remarkable combinations of Sjögren's syndrome with lymphoproliferative disorders i.e. non-classifiable lymphoproliferative disease (case 1), Hodgkin's disease (case 2), reticulum cell sarcoma (case 3), and asymptomatic paraproteinemia of type IgM/K (cases 4 and 5). In case 1, manifestation of a lymphoproliferative disorder was preceded by autoimmune hemolytic anemia. In agreement with communications from several other authors, our observations confirmed the frequent occurrence of autoantibodies in patients with Sjörgren's syndrome. Forty-two more cases of lymphoproliferative disease in Sjögren's syndrome were found in the literature (Table 4). Pathologenetic problems arising from these nosological combinations are discussed. | |
| 1216249 | Increased frequency of HL-A8 in Sjogren's syndrome. | 1975 Nov | The histocompatibility antigen, HL-A8, was found to be elevated in patients with Sjogren's syndrome. Among 24 patients, the frequency of HL-A8 was 58% compared to 21% among controls (P less than 0.001 after correction). With the addition of this disorder to the list of other autoimmune diseases associated with HL-A8, it now seems possible to postulate a single basis autoimmune defect gene in high linkage disequilibrium with HL-A8. | |
| 7420336 | Eosinophilic fasciitis: report of a case with features of connective tissue diseases. | 1980 Jul | A patient suffering from eosinophilic facsiitis is described and the literature reviewed. The original description of eosinophilic fasciitis was that of a benign scleroderma-like disease with eosinophilia, hypergammaglobulinemia and diffuse thickening and inflammation of the fascia and subcutaneous tissue. Our patient like a few others, presented additional findings, namely, Raynaud's phenomenon and mild myhositis. She is the first patient described with Sjögren's syndrome. It is important that eosinophilic faciitis be recognized clinically because it seems to be a benign and treatable entity. | |
| 7391607 | Immune complexes and reticuloendothelial system function in human disease. | 1980 May | The interrelation between the presence of circulating antigen-antibody complexes and the functional status of reticuloendothelial system Fc-receptors was studied in patients with systemic lupus erythematosus and Sjogren's syndrome. Both groups of patients had a high prevalence of circulating immune complexes as detected by the 125I-Clq binding assay and the Raji cell radioimmune assay. A number of patients with both diseases were found to have abnormal reticuloendothelial system Fc-receptor function, as measured by the clearance of IgG-sensitized, 51Cr-labeled autologous erythrocytes. In patients with systemic lupus erythematosus there was a high correlation between the presence and levels of immune complexes and abnormal clearance rates. In Sjogren's syndrome on the other hand there was no correlation between the presence or levels of immune complexes and clearance rates. In this disease patients with normal rates of clearance tended to have disease limited to exocrine glands, while patients with abnormal clearance had evidence of more widespread tissue damage. These findings are consistent with the hypothesis that defective reticuloendothelial system function may lead to the prolonged circulation of immune complexes, thereby contributing to tissue damage. | |
| 582651 | [Pleuropericarditis: early systemic manifestation of an active chronic hepatitis (author's | 1979 | A case of relapsing pleuropericarditis is reported in which no etiological factors were found initially, especially in relation to any possible collagen disease. A retrospective review of the clinical, biological, and histological findings, coupled with the nature of the progression of the disease, suggested to the authors that this was the first expression of a systemic disease which later developed signs of Gougerot-Sjögren's syndrome, Hashimoto's thyroiditis, and, three and a half years later, an active chronic hepatitis. | |
| 217203 | Collagenase-induced experimental arthritis. | 1979 Jan | Rabbits were injected intraarticularly three times with 0.5 ml of 10, 50 or 100 mg% purified rheumatoid synovial collagenase or with identical amounts of trypsin. 18 hours after the last injection the collagenase-injected animals showed distinct cellular exudation into the synovial fluid and acute arthritis; one week later there was a decrease of the cell count in the synovial fluid and appearance of proliferative synovitis, while 3 weeks later there was no exudation and less chronic inflammation but distinct fibrosis of the synovium. A direct action of collagenase on the connective tissue components would seem to be responsible for these changes. No pathologic alteration of the cartilage was observed. Trypsin-injected control animals showed negligible cellular exudation and no pathologic alteration of the synovium. | |
| 7164527 | Nodular regenerative hyperplasia of the liver. Report of two cases associated with autoimm | 1982 Dec | Nodular regenerative hyperplasia of the liver (N.R.H.) is an uncommon clinicopathological entity characterized by diffuse regenerative hepatocytic nodules without fibrosis. Grossly the lesion is often mistaken for cirrhosis. The etiology and pathogenesis are unknown. We report two new cases of N.R.H. diagnosed by liver biopsy. Peritoneoscopically the liver showed a nodular surface resembling micronodular cirrhosis. Both patients showed some clinical and immunological features of autoimmune disease, and in both cases N.R.H. was associated with chronic active hepatitis. We discuss the pathological differential diagnosis of N.R.H., its relation to other associated diseases and review the hypotheses for the pathogenesis of this condition. | |
| 7099932 | [Mechanisms and prognosis of neutropenia in Felty's syndrome. 27 cases (author's transl)]. | 1982 May 1 | Twenty patients with Felty's syndrome were investigated. Isotopic studies of polymorphonuclear neutrophils, bone marrow biopsies and autoradiographies, and cultures of granulous stem cells showed that neutropenia resulted from three mechanisms acting simultaneously: hypermargination of the neutrophils predominantly in the spleen, decreased production of granulocytes in the bone marrow, and peripheral hyperdestruction of the neutrophils. Anti-granulocyte antibodies were detected in 3/12 patients. Other factors present in the serum of 2/4 patients seem capable of inhibiting the growth of granulocytic stem cells. Secondary bacterial infection (77%) may explain the severity of the prognosis: 13 out of 27 patients died 4 years on average after neutropenia was diagnosed. | |
| 158362 | Serum-serum interactions in autoimmune mice. | 1979 Oct | Sera from a majority of old, sick mice of the MRL/l strain interact with other MRL/l sera to form visible immunoprecipitates and fix complement. The mouse sera can be divided into two sets such that interset interactions are far more common than intraset ones. The reactive principle in each mouse serum is IgG in the form of an intermediate-sized complex. Reactivity between sera is dependent on IgG anti-IgG specificities. | |
| 6461592 | [Ankylosing spondylitis (Bechterew's disease)--a current review (author's transl)]. | 1981 Nov | Ankylosing spondylitis is a disease with clinically and radiologically very variable features. It is the intention to direct the attention from the old by orthopedists' influenced association of the stiff back to the polymorphism of the disease especially to the early stages which still frequently are recognized too late. The paper deals with the nosology, the various states of the clinical course with the numerous radiological criteria including therapeutical approaches. | |
| 7356791 | Ocular inflammation associated with Yersinia infection. | 1980 Jan | We studied characteristics of ocular inflammation associated with Yersinia infection in 23 patients. After an acute onset with fever, diarrhea, and abdominal pain, 22 patients developed arthritis, 11 patients developed myalgia, 11 patients developed Reiter's syndrome, 17 patients developed acute anterior uveitis, and nine patients developed conjunctivitis. Sacroiliitis was found in 12 patients. The patients had high erythrocyte sedimentation rates, leukocytosis, and lack of antinuclear antibodies and rheumatoid factor. All 17 patients tested had HLA-B27 antigen. The patients with acute anterior uveitis showed aqueous flare, cells, fine keratic precipitates, and often exudates, posterior synechiae, vitritis, and macular edema. Acute anterior uveitis was mostly unilateral and resolved during corticosteroids on the average during the first six weeks; recurrences were seen in about half of the cases. Conjunctivitis was generally mild with no chemosis, follicles, or keratitis; and it resolved in one week without treatment. Our results indicate that in HLA-B27 positive patients infective agents can trigger acute anterior uveitis or conjunctivitis, which often occur together with rheumatic diseases. | |
| 300753 | Studies on antigen-induced arthritis in mice. III. Cell and serum transfer experiments. | 1977 May | Antigen-induced arthritis in mice occurs after immunization and subsequent intraarticular challenge with methylated bovine serum albumin (mBSA). In adoptive transfer experiments, susceptible C57BL mice and resistant CBA mice were compared in their capacity to express delayed-type hypersensitivity (DTH) by ear assay, and to express arthritis. The expression of DTH could be transferred incrementally by lymphoid cells in C57BL mice, but not in CBA mice. Both immune lymphoid cells and, to a much lesser extent, serum transferred the capacity to develop arthritis in C57BL mice. The reactivity of transferred cells was abolished by anti-Thy-1 but enhanced by enrichment for T cells with anti-immunoglobulin columns. If this model disease can be equated with human rheumatoid synovitis, the lesions in the human disease would be an expression of a T cell-dependent activity. | |
| 61710 | Pharmacology of sinomenine, an anti-rheumatic alkaloid from Sinomenium acutum. | 1976 Feb | The root and stem decoctions of Sinomenium acutum Rehd. et Wils. (formerly Sinomenium diversifolius Diels, one type of Fang-chi (Chinese)) have been used as a folk remedy for neuralgia and rheumatoid arthritis in many areas of the Far East. In Japan and China various viny plants have been identified as Fang-chi (Boi in Japanese) since antiquity. This uncertain nomenclature has made it difficult to evaluate the efficacy of the Fang-chi described in the classic literature. Among traditional Fang-chi plants only Sinomeniumacutum has been demonstrated to contain the alkaloid sinomenine, which is now known to be effective in neuralgia and rheumatic diseases. Sinomenine is a unique plant alkaloid, as it potently releases histamine in association with degranulation of tissue mast cells in mammalian tissues. This action occurs preferentially in the skin and joint capsules. The released histamine is responsible for the dominant pharmacological actions of sinomenine, such as vasodilatation, increased vascular permeability, acceleration of the thoracic and peripheral lymph flow, contraction of plain muscles, increased peristalsis of the intestines, and stimulation of gastric acid secretion. At toxic doses of sinomenine, convulsive central excitation was observed in most laboratory animals. Clinical side effects encountered with high doses of injected sinomenine or of decocted Sinomenium acutum were: injection site flare, pruritus in the head and upper part of the body, edema around the lips and eyelids, and temporary cephalalgia. Most of these side effects were reduced by classical antihistamines (H1-receptor antagonists). Daily subcutaneous injections of sinomenine for more than one week produced an analgesic effect in mice. Granulation tissue growth and adjuvant arthritis induced in rats were both inhibited by daily injections of a small dose of sinomenine hydrochloride or histamine dihydrochloride. These inhibitory effects were mediated through histamine H2-receptors probably on fibroblasts (for granulation tissue growth) and on T-cells (for adjuvant arthritis), since these effects were clearly inhibited by the H2-antagonist burimamide but not by the H1-antagonist mepyramine. The anti-rheumatic effect on Sinomenium acutum are probably genuine and can probably be attributed to the histamine-releasing properties of sinomenine. | |
| 465096 | The clinical significance of Raynaud's phenomenon in systemic lupus erythematosus. | 1979 Aug | In a prospective study of 226 patients with systemic lupus erythematosus (SLE), 91 patients (40%) had Raynaud's phenomenon. These patients were compared to 135 patients without Raynaud's phenomenon. Patients with Raynaud's phenomenon had a greater incidence of arthritis (P less than 0.02), malar rash (P less than 0.003), and photosensitivity (P less than 0.03), and a lesser incidence of severe renal disease as manifested by serum creatinine over 3.0 mg/dl (P less than 0.007) or creatinine clearance below 60 ml/minute. Patients with Raynaud's phenomenon were less likely to have severe, life threatening disease and received a lower average monthly (P less than 0.01) and a lower peak daily corticosteroid dose (P less than 0.01). Fourteen patients (16%) with Raynaud's phenomenon died, compared to 41 without (30%) (P less than 0.03). Raynaud's phenomenon in patients with SLE is associated with milder disease and may be regarded as a favorable prognostic sign. | |
| 7032769 | Autoantibodies to a regulatory T cell subset in human ageing. | 1981 Aug | Anti-T cell autoantibodies were detected in some aged humans. Non-immunoglobulin-bearing (Ig-) cells were isolated from the peripheral blood of normal human donors by negative selection through Ficoll, using sheep erythrocytes coated with rabbit anti-human Ig. The Ig- cells were then reacted with sera from 83 individuals ranging in age from 60 to 99 years; 36% of the serum samples were noticeably reactive with the Ig- cells (average reactivity 28%). The peripheral blood lymphocytes from some of the aged individuals were also tested for levels of Ig-secreting cells in a reverse haemolytic plaque assay; there was a six- to eight-fold increase in the number of plaque-forming cells (PFC) from those individuals whose sera contained appreciable amounts of anti-T cell antibody, as compared with those whose sera contained little or no anti-T cell antibody. Isolated Ig- cells from these individuals were also examined for the presence of regulatory T cell subsets, using sera from juvenile rheumatoid arthritis (JRA) patients. The Ig- cells from the subjects who had no detectable anti-T cell antibodies in their sera and near normal PFC levels were reactive with the JRA sera, whereas the Ig- cells from individuals with increased numbers of PFC and with serum anti-T cell antibodies were only slightly reactive with the JRA sera. These data suggest that a majority of the regulatory JRA+ subset of T cells had been lost in the latter group. When sera from aged individuals containing anti-T cell autoantibodies were reacted with JRA-, Ig- cells isolated from a normal human donor, little positive reactivity was seen, indicating that the autoantibodies in sera from aged humans and from some JRA patients are directed against similar T cell subsets. | |
| 3934902 | Lymphoid nodules and nodular lymphoid hyperplasia in bone marrow biopsies. | 1985 | Out of 2,474 bone marrow biopsies we have observed 330 cases (13.3%) with presence of lymphoid nodules (LN). LN were frequent in old age (24.6% over 80 years), in females (17%) and in some diseases, such as rheumatoid arthritis and systemic lupus erythematosus (73.7% of the cases), partial aplasia (34%), hypersplenism (30.4%), hemopoietic dysplasia (25%), chronic renal failure (20.4%), polycythemia vera (20.2%), idiopathic thrombocytopenic purpura (18.8%), acute leukemia (17.7%). Nodular lymphoid hyperplasia of the bone marrow was found especially in systemic autoimmune diseases (26.3%), hypersplenism (9.8%), preleukemia (7.3%) and acute leukemia (4.2%). The presence of excessive medullary LN could indicate a bone marrow microenvironment damage, possibly of autoimmune origin. | |
| 3839482 | Aluminum intake from non-prescription drugs and sucralfate. | 1985 | The use of non-prescription antacids to control hyperphosphatemia has been implicated as a primary cause of aluminum intoxications in patients with reduced renal function. Additional reports suggest that oral aluminum intake may have adverse effects on mineral metabolism of patients with normal renal function. The non-prescription drugs that contain substantial quantities of aluminum salts include some antacids, buffered aspirins, antidiarrheals, and vaginal douches. Sucralfate, an anti-ulcer drug available by prescription, is the aluminum salt of sucrose sulfate. If taken as directed, the daily aluminum intake from the antacids can be as much as 5,000 mg. When aluminum buffered aspirins are used as part of the drug therapy for rheumatoid arthritis, aluminum intake can be elevated by 700 mg/day. Although aluminum intoxications have been reported among patients with reduced renal function, existing reports are not sufficient to estimate whether the chronic elevation of aluminum intake from drugs is causing adverse health effects among other patient populations. |
