| 2828435 | Scintigraphy of the salivary glands in Sjögen's syndrome. | 1987 Dec | Scintigraphy of the salivary glands with technetium-sodium pertechnetate (99mTc) was undertaken on 320 patients with oral dryness or connective tissue disease using a computer assisted method that gave quantitative results about the major salivary gland function. Compared with clinical and histological data, scintigraphy provides a sensitive method, even though it is not specific, for detecting minimal injuries to salivary glands in patients suspected of having Sjögen's syndrome. Moreover, it might differentiate between the Sjögen-like syndrome and the sequelae of radiotherapy in patients with bone marrow graft. Scintigraphy of the major salivary glands could therefore form part of the routine investigation of patients with Sjögen's syndrome. | |
| 1907094 | Light chain composition of serum granulocyte binding immunoglobulins. | 1991 Jul | Serum granulocyte binding IgG, IgM, and the light chain composition of granulocyte binding immunoglobulins were measured in 58 adult subjects, including 8 normal individuals, 6 with Felty syndrome, 6 with chronic idiopathic neutropenia, 32 with B-cell chronic lymphocytic leukemia (CLL), and 6 with multiple myeloma. An abnormal kappa/lambda ratio of granulocyte binding immunoglobulins was detected in 12 of 32 patients with CLL. Neutropenia in patients with CLL did not correlate with an abnormal kappa/lambda ratio or excess granulocyte binding IgG, but did correlate with granulocyte binding IgM (P less than 0.02). Eight of the 12 patients (5 with chronic idiopathic neutropenia and 3 with Felty syndrome) with an immune neutropenia without underlying neoplastic disorder had light chain restricted granulocyte binding immunoglobulins. Of all patients' sera with light chain restriction, 76% were of lambda light chain isotype. Thus, the frequent detection of light chain restriction of granulocyte binding immunoglobulins is not a reflection of malignancy but is suggestive of the somatic mutation of immunoglobulin light chain genes. | |
| 2041854 | Sjögren-like pluriglandular exocrine insufficiency after drug-induced toxic epidermal nec | 1991 Feb | We present the case of a patient that progressively developed xerophthalmia, xerostomia, cutaneous xerosis and exocrine pancreatic insufficiency 3 months after metamizole-induced toxic epidermal necrolysis. Though the association of Sjögren's syndrome and exocrine pancreatic impairment is well established, the Sjögren-like syndrome after drug-induced toxic epidermal necrolysis in association with such a wide exocrine glandular insufficiency has not been previously described, to our knowledge. | |
| 2222196 | [A case of mixed connective tissue disease developed into overlap syndrome of progressive | 1990 Jun | We encountered a patient who developed an overlap syndrome of progressive systemic sclerosis (PSS), systemic lupus erythematosus (SLE), polymyositis (PM) and Sjögren's syndrome (SjS) while we were treating her for mixed connective tissue disease (MCTD). This 42-year-old woman had been photosensitive since 18 years of age. In 1986, Raynaud's phenomenon, swollen hands and arthralgia appeared; therefore, we started to treat this patient based on a diagnosis of MCTD. At that time, her anti-RNP antibody titer was 82,920, but she was negative to anti-Sm antibody. In 1988, she was admitted to our hospital with chief complaints of aggravation of polyarthralgia and myalgia. On physical examination, she showed difficulty in opening her mouth, systemic dermal sclerosis, a decrease in muscular strength and rales. In laboratory tests, her myogenic enzyme level was increased, and she was found to be positive to LE cells, antinuclear antibody, anti-DNA antibody, anti-ENA antibody and anti-SSA antibody. Furthermore, histological features clearly corresponding to those of PSS were found by skin biopsy, myogenic changes by electromyography, evidence of chronic inflammation of the salivary glands by lip biopsy, and proliferative changes in the mesangium were detected by renal biopsy. The concept of MCTD, especially the differences from overlap syndrome, is vague. Therefore we need further study about many cases. Since there have been no reports on cases having sufficient evidence of the development of the overlap syndrome of PSS, SLE, PM and SjS during a course of MCTD, our patient would provide very useful data contributing to the study of MCTD. | |
| 2810786 | [A cyclic thrombocytopenia associated with Sjögren syndrome]. | 1989 Jul | A 51-year-old women in menopause was admitted because of intermittent purpura. She was diagnosed as having cyclic thrombocytopenia. One platelet cycle lasted for about 22 days with platelet count fluctuating from 1.0 X 10(4)/microliters to 31.0 X 10(4)/microliters. The platelet-associated immunoglobulin was correlated with the platelet cycle. The rheumatic factor, antinuclear antibody, antimicrosome antibody, anti-thyroglobulin antibody and platelet binding immunoglobulin were all positive but did not fluctuate during the cycle. The platelet life-span was shortened. The mean platelet volume fluctuated during each cycle. The lipid emulsion test was prolonged. Symptoms of Sjögren syndrome and purpura appeared at the same time. It was strongly suggested that purpura was caused by cyclical destruction of platelets by reticuloendothelial system. | |
| 3293256 | [Treatment of Sjögren's syndrome with protease inhibitors]. | 1988 | The authors reported the results of therapy of 28 patients with primary and secondary Sjogren's syndrome by iv injections of protease inhibitors (contrykal and trasylol). Findings of clinical and laboratory tests showed a significant increase in salivation and lacrimation. The elimination of concomitant oral candidosis raised the efficacy of treatment of xerostomia in many patients. | |
| 3260692 | [HLA antigens in patients with Sjögren's syndrome]. | 1988 | HLA-antigens were studied in 116 Greek patients: 22 with pSS, 14 with sSS and RA, 26 with classical RA and 420 healthy controls. A statistically significant increase in HLA-DR5 was observed mainly in pSS patients with anti-Ro (SSA). A significant increase in HLA-B8, HLA-DR3 and HLA-DR5 was observed in pSS patients with anti-La (SSB) antibodies as compared to the controls. | |
| 3586572 | Functional Fc-receptor defect of polymorphonuclear leukocytes in a patient with Sjögren's | 1987 Apr 1 | We investigated polymorphonuclear leukocyte (PMN) function in a 50-year-old woman with primary Sjögren's syndrome (SS). The respiratory burst of PMN was monitored by luminol-enhanced chemiluminescence using zymosan, opsonized zymosan, zymosan-activated serum, and phorbol-myristate-acetate, as well as serial dilutions of aggregated immunoglobulin (aggIg) as Fc-receptor (FcR) stimulus. The effects of serum on the chemiluminescent response as well as the binding of aggIg to PMN were also compared. We found the patient's PMN not to respond to stimulation by aggIg, only the highest concentration (greater than 180 micrograms/ml) induced a marginal chemiluminescent response in the patient. By contrast, incubation of the patient's PMN with other stimuli resulted in responses similar to those in a healthy control. Binding of aggIg to PMN was higher in the patient (3.6% vs 1.5% of the radioactivity added in the control). Sera of patient and control induced similar chemiluminescence on PMN as did that of another human serum. Our data indicate a selective functional FcR defect of PMN despite unimpaired binding of aggIg in a patient with SS. | |
| 1768750 | [Pulmonary fibrosis as a presentation form of the Jo-1 syndrome]. | 1991 Aug | Jo-1 syndrome is a disease recently described, included on the list of connective tissue diseases. Its clinical features are myositis and/or pulmonary fibrosis associated to the presence of precipitant antibodies against intracellular enzyme call histidine T-RNA synthetase. This antibody is related to pulmonary fibrosis associated to myositis and some scientist gave predictive value on the onset of pulmonary fibrosis in patients with myositis. However, isolated association of pulmonary fibrosis have been exceptionally described. A patient with severe interstitial pulmonary affliction and positive Jo-1 antibody without myositis is presented. The actual knowledge of the disease and its association is reviewed. | |
| 2054966 | Interstitial nephritis in patients with systemic lupus erythematosus: a manifestation of c | 1991 Jan | In order to estimate the frequency of functionally relevant tubular damage in SLE patients we used the presence of overt renal tubular acidosis as an indicative parameter of interstitio-tubular damage in a cohort of 109 SLE patients who were well characterized for potential Sjögren's syndrome. Only two patients had overt renal tubular acidosis and interstitial nephritis without major glomerular involvement. Both patients, aside from having systemic lupus erythematosus, had a number of clinical features of concomitant primary Sjögren's syndrome. Based on the results obtained and the analyses of previously published cases, we put forward the hypothesis of simultaneous primary Sjögren's syndrome as the prevailing associative factor for the rare occurrence of isolated interstitial nephritis in SLE. | |
| 2558824 | Virus infection induces redistribution and membrane localization of the nuclear antigen La | 1989 Dec | To investigate the possibility that anti-La (SS-B) antibodies in Sjögren's syndrome were induced by virus infection we studied the distribution of La in virus-infected human cell lines. Three monoclonal antibodies to La were used with monoclonal anti-Sm (derived from MRL/lpr lupus mice) and anti-rat immunoglobulin antibodies as controls. In uninfected cells La was predominantly in the nucleus. Twenty-four hours after infection of HEp-2 cells with adenovirus 2, the La and Sm antigens appeared to aggregate and accumulate in the periphery of the nucleus and, after 48 h, La was seen in the cytoplasm and cell membrane. No cytoplasmic or membrane expression of Sm was seen. Infection with adenovirus or cytomegalovirus caused a 2-13-fold increase in the concentration of La in three cell lines. Treatment of HE--2 cells with interferon-gamma (IFN-gamma) and infection with Epstein-Barr virus and cytomegalovirus caused cytoplasmic, but no definite membrane expression of La. The appearance of La on the surface of virally infected epithelial cells together with IFN-gamma induced class II expression could form the basis of a T cell dependent mechanism for anti-La autoantibody induction. | |
| 2610608 | [Necrotizing sarcoid-like granulomatous vasculitis of the lung in a female patient with li | 1989 | A case of necrotizing sarcoid-like granulomatous vasculitis (NSGV) in a female with liver cirrhosis (probably of virus etiology) complicated with systemic manifestations (skin vasculitis, syndromes of Raynaud and Sjögren). NSGV was diagnosed on the basis of the autopsy findings. Giant cell, epithelioid and macrophagal granulomas that differed from those in sarcoidosis by the presence of central necrosis, were found histologically in the walls of lung vessels and bronchi of various caliber. Keeping in mind a possible immuno-complexed pathogenesis of vasculitis in liver cirrhosis and NSGV as well as a probable viral etiology of liver cirrhosis it is likely that NSGV resulted from the vascular damage by immune complexes containing hepatitis virus antigens. Another peculiar feature of this observation was development of pulmonary hypertension. | |
| 3394103 | [Comparative evaluation of various methods of treatment of patients with Sjögren's diseas | 1988 | The paper is concerned with the results of a follow-up and treatment of 97 patients with Sjogren's disease and syndrome. When disease was at its height they were treated in a hospital, when the activity of a process was on a decrease or absent at all--in the consultation center of an outpatient clinic. Control was exercised in an open study. Glucocorticosteroid therapy was indicated at the height of disease at early stages and much less effective at late stages or in the absence of disease activity. At early stages this type of therapy resulted in substantial improvement of lacrimation and salivation and a positive time course of clinical symptoms. Chloroquine contributed to disease stabilization but did not prevent progression in some of the patients. Administration of local substitution therapy only was not indicated because during a follow-up period the majority of these patients developed xerotic symptoms. | |
| 2444171 | HLA class I and II, interferon, interleukin 2, and the interleukin 2 receptor expression o | 1987 Aug | Labial biopsy specimens from eight patients with primary Sjögren's syndrome (SS), 10 patients with secondary SS, and three healthy controls were studied with monoclonal antibodies identifying HLA class I and class II antigens; interferon-alpha, beta, and gamma; interleukin 2 (IL2); and the IL2 receptor (Tac) among others. In the normal biopsy specimens there was evidence of HLA class I and, to a lesser extent, class II antigens in both ducts and acini, though this was much less marked than in the Sjögren's biopsy specimens. Interferon-gamma staining, but not interferon-alpha or beta, was also considerably enhanced in the biopsy specimens from the patients with Sjögren's syndrome. These data support the view that in Sjögren's syndrome the release of interferon-gamma may be involved in the induction of class II determinants. Our observations were broadly similar in both primary and secondary Sjögren's syndrome except that patients with primary Sjögren's syndrome tended to have more diffusely scattered T lymphocytes. | |
| 1958099 | Pneumococcal septic arthritis after splenectomy in Felty's syndrome. | 1991 Oct | A patient with Felty's syndrome who developed bilateral knee septic arthritis and septicaemia due to Streptococcus pneumoniae is described. She had had a previous splenectomy for symptomatic thrombocytopenia, having received pneumococcal vaccine before the operation. Measurement of antibody to the 23 vaccine serotypes showed protective concentrations before infection to just two. The infecting serotype was not represented in the vaccine, but a vigorous antibody response to this serotype occurred. The patient also developed glomerulonephritis due to immune complex deposition. | |
| 1918495 | Polymyositis: a manifestation of chronic graft-versus-host disease. | 1991 Sep | Polymyositis developed in a patient who had had bone marrow transplants for the treatment of acute myeloid leukemia. There was no previous evidence of graft-versus-host disease. Polymyositis has previously been reported to be associated with graft-versus-host disease; this article suggests that polymyositis may represent its sole manifestation. | |
| 1700996 | Mapping of epitopes on the La(SS-B) autoantigen of primary Sjögren's syndrome: identifica | 1990 Dec 1 | Autoepitopes on the ribonucleoprotein La(SS-B) were identified by using recombinant La(SS-B) polypeptides and sera from 166 patients with the antinuclear autoantibody anti-La(SS-B). The La(SS-B) polypeptides were encoded by polymerase chain reaction-derived overlapping or nonoverlapping fragments of the La(SS-B) gene, which encodes a protein of 408 amino acids (aa). Of the 166 sera tested, 99% reacted with a fusion protein comprising the first 107 N-terminal aa (LaA); 91% reacted with a fusion protein comprising aa 111 to 242 (LaC), and 91% reacted with a fusion protein comprising aa 346 to 408 (LaL2/3) at the C terminus of La(SS-B). The order of immunodominance as assessed by the number of sera reacting with each epitope and the strength of the reactivity was LaA (aa 1 to 107) greater than LaC (aa) 111 to 242) much greater than LaL2/3 (aa 346 to 408). Cross-reactivity was observed between antibodies eluted from LaC (aa 111 to 242) and LaL2/3 (aa 346 to 408), but there was no significant primary sequence homology between the two regions. The LaC region contained at least two epitopes, one encompassing a putative RNA-binding motif (aa 112 to 187) which was recognized by 83% of patient sera. Serial serum samples from three patients showed that the antibody response to La(SS-B) was initially directed to the N terminus (LaA, aa 1 to 107), but over a period of time all three major epitopes, including that encompassing the putative RNA-binding motif, were recognized. This result suggests that the primary immune response to La(SS-B) is restricted to an immunodominant epitope. As the specificity of the autoantibody response broadens, it includes the RNA-binding motif, which may have important implications for the expression of disease. | |
| 2085939 | [Digital sialography]. | 1990 Sep | Sialography is at present performed either by the subtraction mode or conventional technique only. We utilised a high-resolution digital radiography system with a 1024 x 1024 matrix in 17 patients with diseases of the salivary glands. Digital subtraction ductography in lateral projection was followed by digital radiography in adequate projections. In that way advantages of both methods could be combined in one. Additional advantages are possibilities of storage and communication of the digital data. | |
| 2192076 | Streptococcus pneumoniae acute suppurative parotitis in a patient with Sjögren's syndrome | 1990 Jun | A case of suppurative parotitis due to Streptococcus pneumoniae is reported in a patient with Sjögren's syndrome. The rarity of this condition is noted by a review of the literature. | |
| 2654284 | No specific association between primary biliary cirrhosis and bacteriuria? | 1989 Mar | 160 consecutive patients with primary biliary cirrhosis (PBC) (M:F, 13:147; total samples 286), 140 patients with other chronic liver disease (CLD) (M:F, 75:65; total samples 200), and 28 patients with primary Sjögren's syndrome (all F; total samples 37), were examined for bacteriuria over 6 months by midstream urine (MSU) examination. The overall prevalence of bacteriuria in PBC was 11.2% (7.5% on first MSU), in CLD 12.1% (10.7% on first MSU), 18.4% in the 65 female CLD patients, 10.7% in Sjögren's syndrome patients (3.5% on first MSU). The prevalence of bacteriuria was related to the age of the patient (P less than 0.02) in PBC and to the presence or absence of cirrhosis in both PBC and CLD (P less than 0.02). There was no difference in the prevalence of bacteriuria between PBC and CLD patients taken as a whole or among females alone, cirrhotic or non-cirrhotic groups. In a second prospective study of the cumulative incidence of bacteriuria in PBC versus CLD and Sjögren's no significant differences between groups was observed but among 29 PBC patients the cumulative proportion of positive tests for bacteriuria after 5 months (monthly testing) was 34%. We conclude that there is no specific association between PBC and bacteriuria compared with the prevalence of bacteriuria in other CLD. |
