| 7009856 | Immunoglobulin-secreting cells in SLE: correlation with disease activity. | 1980 Nov | Peripheral blood lymphocytes which contain and secret immunoglobulin were identified by fluorescent staining and a reverse hemolytic plaque assay. Significantly increased numbers of these cells were found in patients with active systemic lupus erythematosus compared with patients with rheumatoid arthritis, bacterial infections and normal controls. The increased numbers of these circulating activated B cells closely correlated with clinical and laboratory indices of disease activity, indicating their potential value in the management of lupus patients. However, the demonstration of pseudo-plaques in assays of lymphocytes from some lupus patients emphasizes the need to establish the true secreting nature of the plaques detected. | |
| 7425830 | Severe upper limb ischemia. | 1980 Oct | Severe upper limb ischemia is uncommon, and patterns typical of lower limb ischemia are seldom seen. The conditions of 31 patients with actual or threatened gangrene or severe disability were evaluated from 1969 through 1978. Causes of ischemia included emboli, arteriosclerotic occlusions, trauma, thoracic outlet compression, and small-artery occlusions associated with Raynaud's phenomenon, rheumatoid arthritis, or scleroderma. Five patients had emboli from lesions in peripheral arteries, and two patients had ulnar artery occlusions. Twenty-three patients had operations with no deaths. There was one operative failure. Operative angiograms were used routinely. Patients with emboli from the heart received heparin sodium after operation. Sympathectomy improved the conditions of two patients with Raynaud's phenomenon and of one patient with ulnar artery occlusion. One third of the patients had significant arteriosclerotic lesions in other locations. | |
| 232569 | ACTH-adrenal system and exogenous steroids. | 1979 Jul | The results obtained from a research on 100 patients of both sexes affected with bronchial asthma, chronic obstructive bronchopathy, rheumatoid arthritis, haematological disorders and some other pathological forms, all depending on steroid therapy, are reported in this paper. The treatment was carried out using a new chronopluricorticoid (Dutimelan 8 15). The clinical efficiency is comparable to that obtained by the traditional steroid treatment with the advantage that symptoms of hypercorticism were absent or insignificant. The authors believe that such excellent results are to be attributed to the particular chronopharmacological characteristics of this preparation. | |
| 696236 | Osteoarthropathy of hepatolenticular degeneration. | 1978 Jun | Ninety-six joints of 25 patients with hepatolenticular degeneration have been studied by means of scintigraphs with technetium (99mTc), a method which can disclose early synovial inflammation and postinflammatory articular degeneration. Signs of synovitis were found in 22 joints of 10 patients (40%) and degenerative changes were present in 15 joints of eight patients (32%). Eleven patients complained of joint pains; in four of them they were the presenting symptom. The radiological study showed osteoporosis in 22 patients (88%); flexion deformity was found in two cases, anomalous osteophytes in two, and signs of growth arrest, features of rheumatoid arthritis and aseptic necrosis in one case each. The pathogenesis of osteoarticular changes in Wilson's disease is discussed. | |
| 591304 | Renal amyloidosis: immunofluorescence and electron microscopy studies. | 1977 Nov | Renal biopsy specimens of 15 patients with renal amyloidosis were studied by immunofluorescence microscopy. The amyloidosis was associated with chronic pulmonary disease in five, rheumatoid arthritis in one, chronic lymphocytic leukemia in one, and familial Mediterranean fever in five patients. In three patients no associated condition could be determined although the pattern of organ involvement resembled that of secondary amyloidosis. IgG and complement (C3) were demonstrated in the glomerular capillary walls and in the mesangium in all patients. The pattern of the deposits was neither granular nor linear. Ig and C3 appeared as large confluent masses or broad ribbon-like segments. In the six patients studied by electron microscopy the fibrillary formation of amyloid was seen in the mesangium and the glomerular capillary walls corresponding to the Ig deposits. No immunofluorescence or ultrastructural differences were observed among the patients with secondary, inherited and leukemia-associated amyloidosis included in this study. | |

| 3934765 | Pure red cell aplasia in Thailand: report of twenty four cases. | 1985 Jun | Twenty four cases of pure red cell aplasia were reported. No underlying diseases were found in two cases. Of the 22 cases with secondary form, 10 were from infections, mostly gram negative organisms. Three cases had systemic lupus erythematosus, two had autoimmune hemolytic anemia. The following conditions were found in one each: thymoma, thyroid carcinoma, protein calorie malnutrition, rheumatoid arthritis, non-Hodgkin lymphoma and Sheehan's syndrome. Three patients died, two from uncontrolled infection, the other from uncontrolled SLE and subsequently systemic fungal infection. Only one of the 2 primary cases responded to immunosuppressive drugs. The majority of patients with underlying infections, PRCA resolved after the infections were treated. This is the first reported series of PRCA in Thailand. | |
| 3890671 | Prevention and treatment of venous ulceration. | 1985 May | Venous ulcers are related to incompetence of the direct calf and ankle perforating veins, the majority of which follow deep vein thrombosis. Prevention of the latter by intravenous micro-dose heparin (1 unit/kg/hour) is effective, safe and inexpensive. Its efficacy has been proved in two controlled clinical trials. Venous ulcers have been treated by perforating vein ligation, with saphenous ligation and stripping where necessary, and with the addition of permanent knee-length elastic compression stockings in patients with femoro-popliteal incompetence. This regimen has achieved a 92% long-term success rate in patients without rheumatoid arthritis. | |
| 3889245 | The distribution of cathepsin B in human tissues. | 1985 Apr | Cathepsin B is a lysosomal enzyme of importance in many physiological and pathological processes. Its distribution in human tissues was studied by an indirect immunoperoxidase method. Cathepsin B was demonstrated in macrophages, hepatocytes, renal tubules, gastrointestinal epithelium and fibroblasts, confirming previous studies. It was demonstrated for the first time by immunohistology in several other tissues, especially stratified squamous epithelium, transitional epithelium, salivary glands, pancreas, central and peripheral neuronal cell bodies, trophoblast and all endocrine organs. Widespread distribution of cathepsin B has been postulated several times but this is the fullest evidence that the enzyme indeed occurs in many organs. In pathology cathepsin B has so far been thought to be involved in demyelination, emphysema, rheumatoid arthritis and neoplastic infiltration. | |
| 3969536 | Isopycnic ultracentrifugation of immune complexes. | 1985 Jan | Isopycnic ultracentrifugation is frequently applied for preparative isolation of macromolecules. Using bovine serum albumin (BSA)-anti-BSA antibody complexes as a model system, isopycnic banding of complexes was observed in CsCl, Nycodenz, and sucrose gradients. In CsCl gradients, free antigen or antibody could not be separated from the immune complexes. Variations in antigen to antibody ratio from equivalence and in the amount of complement present during complex formation resulted in zone broadening and banding at slightly lower densities in Nycodenz. This was not observed in sucrose. Serum immune complexes were isolated from patients with rheumatoid arthritis or ankylosing spondylitis. Banding of in vivo-formed immune complexes was observed more frequently in sucrose than in Nycodenz. | |
| 6520493 | Arthroscopy of the shoulder joint--a cadaver and clinical study. Part 2: Clinical study. | 1984 Oct | Shoulder arthroscopy was carried out 56 times on 50 patients. Different types of arthroscopes were employed. Anterior and posterior approaches were used. Diagnoses were 21 cases of glenohumeral instability including 17 of recurrent anterior dislocation and subluxation; 2 of voluntary anterior subluxation and 2 of habitual posterior dislocation, 13 of rotator cuff tear, 6 of chronic subacromial bursitis, 2 of fracture-dislocation, 2 of frozen shoulder, 2 of baseball shoulder, one of rheumatoid arthritis, and 3 miscellaneous. The arthroscopic findings in the instability group and rotator cuff tear group were verified. Bankart lesion and Hill-Sachs lesion were identified arthroscopically. The indications for shoulder arthroscopy are outlined. There was no significant morbidity with this procedure. | |
| 6685196 | [Determination of urinary immunosuppressive acidic protein in cancer patients]. | 1983 Sep | The urine levels of immunosuppressive acidic protein (IAP) were measured in patients with and without cancer, using passive hemagglutination inhibition test and 24-h urine samples. In 23 control healthy adults, the urine levels of IAP were 0.13-1.3 mg/day. If an elevation of IAP levels were found in 46 (48%) of 96 cancer patients. Elevated urine IAP levels were found in 6 (18%) of 34 patients with non-cancerous gastrointestinal tract diseases. Increased urine IAP was demonstrated in 11 (58%) of 19 non-cancer patients with rheumatoid arthritis. | |
| 6628574 | Deposition of immune complexes in the mouse eye. | 1983 Sep | The ocular deposition of circulating immune complexes was studied in mice using passive and active immune complex models. In the passive model, immune complexes were made at different antigen-to-antibody ratios and subsequently injected intravenously. In the active model, antigen alone was injected intravenously into immune mice. Ocular localization was studied by immunofluorescence microscopy. In both experimental models a marked deposition of antigen, antibody and mouse C3 could be observed in the scleral capillary area, whereas a weaker deposition could also be observed in the ciliary body, iris and choroid. With the immune complex doses used, only a short (1-2 hr) ocular deposition was observed and no inflammatory signs were seen upon histological examination. The deposition of complexes in the episcleral capillary area could provide a suitable experimental model to analyse the role of circulating immune complexes in the pathogenesis of scleral phenomena associated with rheumatoid arthritis. | |
| 7232771 | Elevated levels of circulating pancreatic polypeptide in inflammatory and infectious disor | 1980 Dec | Circulating levels of pancreatic polypeptide (PP) were found to be elevated when compared to healthy controls in 54% of patients with chronic inflammatory connective tissue disorders (SLE, rheumatoid arthritis, scleroderma, mixed connective tissue disease and temporal arteritis) and in 96% of patients with acute viral or bacterial infections. Significant positive correlations were obtained between the serum values of PP and those of haptoglobin or orosomucoid. Accompanying successful anti-inflammatory treatment of patients with autoimmune disorders, a reduction of PP levels was observed. The findings suggest that the magnitude of increase in PP was associated with the degree of the inflammatory activity. Raised PP levels may contribute to the alterations in carbohydrate and lipid metabolism observed during active inflammatory diseases in man. | |
| 392268 | Cultivation requirements for Treponema pallidum, Mycobacterium leprae and other microbial | 1979 Oct | Atmospheric and biological evolution progressed simultaneously and today certain cell types flourish only at oxygen tensions which were ambient 600 million years ago, i.e., at 5 to 10 mm Hg. In man, a continuous oxygen flow at these pressures is supplied in the skin where Treponema pallidum, Mycobacterium leprae and members of the genus Rickettsia grow best. In vitro studies support the microaerophilic status of these organisms and of certain other microbial and mammalian cells. Vigorous growth in pure culture will await the development of techniques which can maintain these low oxygen tensions at the cell walls of the microbes as they replicate and consume increasing amounts of oxygen. Continuing failure to consistently isolate microbes from active lesions in patients with rheumatoid arthritis or systemic lupus erythematosus may reflect the universal absence of suitable methods for isolation of microaerophilic microbes. | |
| 317005 | [Morphologic indication for the participation of neutrophil granulocytes in rheumatic cart | 1979 Sep | Cartilage destruction in rheumatoid arthritis may be mediated by enzymes of the synovial fluid and by cells of the proliferating pannus tissue. Neutrophilic granulocytes are usually said to affect the cartilage via the synovial fluid, and their local occurrence in the pannus-cartilage border is denied. However, a morphological study on pannus tissue and cartilage by use of histochemistry and immunfluorescence (leucocytes antielastase) exhibited an accumulation of neutrophilic granulocytes in the immediate vicinity of the cartilage in destruction. This result is in contrast to the observation of most investigators reporting studies of the pannus cartilage junction. Experimental datas of the effect of elastase moreover indicate that this enzyme is capable to penetrate into the cartilage and to degrade proteoglycans. Therefore the results show that the occurrence of neutrophilic granulocytes at the pannus-cartilage border is an important phenomenon for understanding the progressive cartilage destruction and that elastase may be at least one enzyme responsible for the degradation of the cartilage matrix. | |
| 605782 | Immunoglobulin concentrations in first-degree relatives of epileptic patients with drug-in | 1977 Dec | Serum immunoglobulins A, G and M were studied in parents and siblings of 16 patients being treated for epilepsy. Five healthy families served as controls. Seven of the patients were low IgA-responders and the rest of the patients had shown normal IgA-levels during treatment. None of the parents and siblings studied showed a serum-IgA deficiency, with the exception of one mother who was being treated for rheumatoid arthritis with naproxen. Low serum concentrations of IgG and IgM were not found. A significantly increased IgM-level was found in first-degree relatives of the low IgA-responders, and the siblings of low 2gA-responders had significantly raised IgA in their sera. | |
| 57640 | Coexistence of protein AA and immunoglobulin light-chain fragments in amyloid fibrils. | 1976 | Coexistence of amyloid fibril protein AA and homogeneous immunoglobulin light-chain fragments was found in the isolated amyloid fibrils of two patients with amyloidosis secondary to rheumatoid arthritis. The light-chain amyloid fibril protein showed antigenic identity with a light-chain amyloid from a patient with primary amyloidosis, which was identified as the VlambdaIV subgroup by amino acid sequence analysis. In the amyloid fibrils isolated from another patient with primary amyloidosis there was a mixture of VlambdaIV and VlambdaV homogeneous immunoglobulin light chains. Thus, a mixture of protein AA had lambda light chains or two different types of homogeneous light chains may be found in the amyloid fibrils of some patients. | |
| 6475325 | [Heart involvement in progressive systemic sclerosis (generalized scleroderma)]. | 1984 May | 17 patients with progressive systemic sclerosis were examined for cardiac involvement using standard ECG, chest X-ray, 24-h Holter ECG, and echocardiography. The control groups consisted of 7 patients with mixed connective tissue disease, 10 patients with systemic lupus erythematosus, and 10 patients with rheumatoid arthritis. The results disclosed a cardiac involvement of 70% using all 4 methods, which is more than is reported in the literature. The data also show that all 4 methods are necessary to diagnose the cardiac involvement. Conduction and rhythm disorders especially are more frequent than in other collagen vascular diseases. The use of calcium channel blockers is discussed as a new therapeutic possibility. | |
| 6320446 | [Psoriatic rheumatism]. | 1984 Jan 26 | Approximately 5% of patients with psoriasis develop chronic inflammatory joint disease which is clearly differentiated from rheumatoid arthritis by several features; absence of prevalence in females, elective involvement of distal joints of hands and feet, negative serologic tests, usually less severe outcome and absence of systemic manifestations. Conversely, psoriatic rheumatism resembles ankylosing spondylitis inasmuch as mainly sacroiliac but also vertebral involvement is common, with, in some instances, development of a typical pelvispondylitis. Thus, psoriatic rheumatism belongs to the group of seronegative spondylarthropathies. The genetic background of psoriatic rheumatism, with the exception of predominantly axial forms which are related to HLA B27, is very similar to that of isolated psoriasis, typified in particular by the frequency of HAL B17, B13 and B38. The immunologic disorders described in psoriasis and, more recently, in psoriatic rheumatism suggest that an immunologic dysfunction probably plays a significant part in the genesis of both conditions; however, the reasons why only a small proportion of patients with psoriasis develop joint disease remain obscure. |
