20478195 | [Experience in the treatment of infections of the total knee arthroplasty.]. | 2000 | This retrospective study evaluates medium-term results of a two-phase treatment of infections of total knee arthroplasty. In the period of 1990-1997 thirty-three infected total knee replacements were treated (once bilaterally) in 32 patients (21 females and 11 males). In 20 cases the basic diagnosis was osteoarthritis and in 13 cases rheumatoid arthritis. The results were evaluated in the interval of 34-82 months after the revision surgery.The success of the therapy was evaluated on the basis of the fulfilment of the following criteria: a functional implant, the period of post-operative follow-up longer than 24 months, the patient subjectively without complaints, good local conditions, laboratory tests tending to the normalization of the values of the sedimentation of erythrocytes and C-reactive protein, radiograph without progression of radioluscent lines, at least 3 months without antibiotics. The success rate of the two-phase revision surgery after the infection of the total knee replacement in the whole group of patients was 72,7 %, due to the additional therapy it increased up to 78,8 % and in patients with osteoarthritis even to 85 %. In rheumatoid arthritis the efficiency of the procedure was substantially lower and reached only 69,2 %. A serious therapeutic problem is posed by the infections caused by streptococci mainly due to their ability to recur. The simplest and least costly of the laboratory methods for the diagnosis and monitoring of the efficiency of the therapy proved to be the regular monitoring of the dynamics of changes in the sedimentation of erythrocytes, also in patients with rheumatoid arthritis. Decisive factors for the success is a timely removal of the infected implant, repeated careful debridement of infected tissues, a sufficiently long interval between individual phases and a longterm targeted antibiotic therapy. Key words: infection of total knee arthroplasty, a twophase therapy of the infection, revision surgery of the total knee arthroplasty. | |
10555028 | Prevention of leg length discrepancy in young children with pauciarticular juvenile rheuma | 1999 Nov | OBJECTIVE: To determine if intraarticular (i.a.) injection of triamcinolone hexacetonide (steroids) used early in the course of pauciarticular juvenile rheumatoid arthritis (pauci JRA) is associated with less leg length discrepancy (LLD) or thigh circumference discrepancy (TCD). METHODS: Children with pauci JRA who had asymmetric lower-extremity arthritis diagnosed before age 7 years in Seattle, Washington (WA; n = 16) and in Chapel Hill and Durham, North Carolina (NC; n = 14) were retrospectively identified. WA children were given i.a. steroids within 2 months of diagnosis; the injections were repeated if synovitis recurred in the same joint or in a different joint. These children were compared with NC children who were not treated with i.a. steroids. Thigh circumference was measured at 10 cm above the patella, and leg length was measured from the anterior superior iliac spine to the mid-medial malleolus, by a single observer. LLD and TCD are reported as the percentage of difference between leg measurements in each subject. RESULTS: The WA and NC subjects had comparable disease severity and duration of followup (in months). Twelve WA children had subsequent i.a. steroid injections (mean 3.25 injections per child over mean +/- SD 42 +/- 11 months). The WA subjects had significantly less LLD (P = 0.005, by Student's 2-sided t-test) and prescriptions for shoe lifts (P = 0.002, by Fisher's 2-sided exact test). There was not a significant difference in TCD between the 2 groups (P = 0.139, by Student's 2-sided t-test). Similar findings were obtained when the analysis was limited to children with monarticular knee arthritis. CONCLUSION: Early and continued use of i.a. steroids may be associated with less LLD in young children with pauci JRA. This may indicate decreased duration of synovitis. | |
11334390 | Autoimmune hepatitis concomitant with hypergammaglobulinemic purpura, immune thrombocytope | 2001 Apr | Sjögren's syndrome occurs as an occasional complication of autoimmune hepatitis, and purpura or thrombocytopenia develops in some patients with this syndrome. This report describes a 62-year-old woman with a 6-year history of autoimmune hepatitis who concurrently had hypergammaglobulinemic purpura, immune thrombocytopenia and Sjögren's syndrome. Treatment with prednisolone resulted in marked improvement of biochemical, hematological and dermatological abnormalities. This case emphasizes the manifestation of purpura or thrombocytopenia as an associated disorder during the course of autoimmune hepatitis concomitant with Sjögren's syndrome. | |
10622459 | Cholinergic-drug induced sicca syndrome in Parkinson's disease: a case report and a review | 1999 Dec | A 67-year-old woman developed severe sicca manifestations after initial treatment of Parkinson's disease with an anti-cholinergic drug, which prompted us to look for the presence of Sjögren's syndrome. The results of sialography, labial salivary gland biopsy, Rose-Bengal test as well as the presence of antinuclear antibody were consistent with the diagnosis of Sjögren's syndrome. The sicca symptoms diminished by cessation of the anti-cholinergic drug, and the parkinsonian features were controlled by levodopa. We suggest that Sjögren's syndrome should be considered, if patients with Parkinson's disease complain severe xerostomia. | |
9539326 | A case of autoimmune cholangitis associated with Sjögren's syndrome and arthropathy. | 1998 Feb | Autoimmune cholangitis (AC) is a recently proposed entity that describes a specific group of patients presenting overlapping features of primary biliary cirrhosis (PBC) and autoimmune hepatitis. The disease is characterized by dinical cholestasis, high titer antinuclear antibody, negative antimitochondrial antibody, and histologically, findings of PBC coexisting with varying degrees of parenchymal inflammation. In this report, we describe a patient with Sjögren's syndrome who fulfilled the diagnostic criteria of AC associated with unique arthropathy compatible with arthritis of PBC. This case illustrates the unusual coexistence of two diseases that may share similar pathogenic processes. | |
9496153 | Neuropeptides of the autonomic nervous system in Sjögren's syndrome. | 1997 Dec | OBJECTIVE: To assess the activity level of the autonomic nervous system in Sjögren's syndrome (SS) and to correlate this with stress. METHODS: Patients with SS (n = 12) and healthy controls (n = 10) were analysed for the content of vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) in their stimulated saliva by radioimmunoassays and for stress by the use of a modified Jenkins Activity Survey (JAS). RESULTS: The data are expressed as median (interquartile range). Salivary VIP output (pg/min) and NPY output (pg/min) were high in SS compared with healthy controls (30.0 (15.6, 36.6) versus 12.3 (9.2, 24.0), p = 0.045, 4.8 (0.6, 24.1) versus 0.7 (0.0, 2.4), p = 0.038, respectively). Patients experienced only a little, but not significantly, more stress than the healthy controls (stress index -2.8 (-7.7, 6.9) versus -5.2 (-12.9, 2.7), p > 0.05). Stress in general was associated with high salivary VIP concentrations (r = 0.41, p = 0.05). CONCLUSIONS: These findings show that adequately processed saliva (containing aprotinin and EDTA as neuropeptidase inhibitors) contains measurable amounts of marker peptides of the autonomic nervous system. Secondly, VIP concentration but not output may be affected by stress, which may act by decreasing watery salivary flow. In patients with SS, VIP and NPY outputs are increased. This may indicate increased leakage into saliva or efforts to compensate for the diminished salivary flow, or both. | |
9411197 | [Still's syndrome in the adult. A report of 8 cases with special reference to diagnostic v | 1997 Sep 15 | BACKGROUND: Adult onset Still's disease (AOSD) is an uncommon, systemic, inflammatory disorder of unknown etiology, characterized by the triad of fever, arthritis and rash. PATIENTS AND RESULTS: We describe 8 cases of AOSD (3 male, 5 female) diagnosed and treated in the Department of Rheumatology from 1980 to 1996. The delay in reaching a firm diagnosis was between 2 and 86 months, due to both lack of specific serum markers and the abundance of possible differential diagnoses. Our therapeutic strategies and results are presented and the value of obtaining serum ferritin levels for both diagnosis and follow-up studies is discussed. The patients data are compared to those of the world's literature on AOSD. CONCLUSION: The differential diagnosis of fever of unknown origin should always include AOSD, because these patients could be spared from invasive and unnecessary diagnostic measures. Increased serum ferritin levels are of particular value in the diagnosis of acute AOSD and the normalization of the serum ferritin value is a reliable indicator of therapeutic success. | |
18432736 | Adjuvant arthritis in the rat. | 2001 May | Adjuvant arthritis (AA) is an induced form of (sub)chronic arthritis. Strains of rats have a varying genetic susceptibility to AA, whereas mice generally are not susceptible. AA is most easily induced with mycobacteria suspended in oil, although in some strains of rats it can be induced with oily adjuvants in the absence of mycobacteria. The disease is a T cell-mediated autoimmune arthritis that is frequently used to study immunological aspects of rheumatoid arthritis (RA) and other arthritic or inflammatory diseases in humans. Furthermore, it is used as a model for developing and testing antiinflammatory drugs. There are no particularly well-defined autoantigens in AA; in this respect, the model resembles spontaneous arthritic diseases in humans. In all susceptible rat strains, the inflammatory process of AA is self remitting, although usually the disease is severe and leads to permanent joint malformations, including ankylosis; a time line for AA development is presented. This unit describes the induction and evaluation of AA and the preparation of adjuvant used to induce AA. | |
11092791 | What we learn from arthritis models to benefit arthritis patients. | 2000 Dec | Chronic arthritis is characterized by persistent joint inflammation and concomitant joint destruction. Animal models have been of great value in understanding potential pathogenetic pathways and studying therapeutic principles. The first models were based on T cell-driven pathways and taught us that arthritis can be induced by a variety of stimuli. This suggests that the involvement of a single (auto)antigen in rheumatoid arthritis is unlikely and suggests that the regulation of arthritis can best be approached via bystander suppression. Insight into the pivotal role of TNF alpha and IL-1 has emerged from studies employing a range of common and also novel transgenic models. Combination treatment with both TNF and IL-1 blockers is warranted to control both joint inflammation and joint destruction. Novel approaches with viral gene constructs of cytokines and cytokine inhibitors teach us that efficient gene therapy is a possibility for small joints. | |
10414252 | [Gougerot-Sjögren syndrome. Risk of lymphoma]. | 1999 Jun 19 | LYMPHOMA RISK: Lymphoma is a very severe complication of primary Sjögren's syndrome: 5 to 10% of patients followed for more than 10 years will develop a lymphoma. Predictive factors include serum monoclonal immunoglobulins or cryoglobulins and a B clone population in accessory salivary glands. TYPICAL CLINICAL AND HISTOLOGICAL PRESENTATION: Mucosal involvement (parotid as well as gastric or pulmonary localizations) is frequent. According to the recent classification of lymphomas, most lymphomas developing in patients with Sjögren's syndrome are B lymphomas of the marginal zone: MALT lymphomas or low-grade nodal monocytoid lymphomas which are sometimes not identified until transformation to the giant cell stage. SIMILARITIES WITH HEPATITIS C LYMPHOMAS: The pathophysiology of lymphoma in Sjögrën's syndrome remains unknown. To date, there is no argument favoring a viral infection or a deregulation of a unique oncogene or anti-oncogene. Certain similarities between lymphomas in Sjögren's syndrome and lymphomas associated with hepatitic C virus would suggest a common pathogenisis: possibly a permanent stimulation of auto-reactive B cells carrying a surface immunoglobulin with rheumatoid factor activity in the target organs of the autoimmune disease. These B lymphocytes would then proliferate secondarily. | |
11791650 | Is Sjögren's syndrome involved in the formation of localised nodular amyloidosis? | 2001 Nov | The case of a patient who presented with Sjögren's syndrome complicated by localised cutaneous nodular amyloidosis is reported. We discuss the possible link between these two diseases. | |
11709452 | Sialometry and sialochemistry: diagnostic tools for Sjögren's syndrome. | 2001 Dec | BACKGROUND: The common occurrence of xerostomia in Sjögren's syndrome (SS) as well as the easy accessibility of saliva supports the use of sialometry and sialochemistry in the diagnosis of SS. Collection and analysis of whole saliva (oral fluid) is currently the routine technique for sialometry, despite the fact that it is rather inaccurate and impure. OBJECTIVE: To assess the value of glandular sialometry and sialochemistry as diagnostic instruments in SS. METHODS: In a group of 100 consecutive patients referred for diagnosis of SS, glandular secretory flow rates and a spectrum of salivary components (sodium, potassium, chloride, calcium, phosphate, urea, amylase, total protein) were assessed. The patients were classified as positive or negative for SS according to the revised European classification criteria. RESULTS: Patients with SS differed clearly from those who tested negative for SS, showing lower submandibular/sublingual (SM/SL) flow rates and an appreciably changed salivary composition of parotid and SM/SL saliva. Besides changes in salivary flow rate and composition, distinct sialometric profiles were observed, characteristic of either early or late salivary manifestation of SS, or of the xerogenic side effects of medication. CONCLUSIONS: Glandular sialometry and sialochemistry are not only useful tools for differentiating SS from other salivary gland disease in clinical practice, but they also have great potential as diagnostic criteria for SS, showing distinct sialometric and sialochemical changes as well as profiles. Being simple, safe (non-invasive), and sensitive (early disease detection), they have three major advantages over other oral tests for SS. | |
11210874 | A simple method to estimate the secretion of saliva from minor salivary glands using iodin | 2001 Feb | OBJECTIVE/HYPOTHESIS: This study was undertaken to detect the faculty of secretion of saliva from minor salivary glands by analyzing a color reaction on a test tape containing iodine and starch that was applied on the lower lip. STUDY DESIGN: A study involving 63 patients with oral dryness, 7 patients with Sjogren syndrome, and 70 healthy individuals was performed. METHODS: A test tape (1 x 1 cm) containing iodine and starch was set on the mucosal area anterior to the labia frenulum for 30 seconds. Because the number of blue spots was considered to correspond to the number of ostia of the salivary gland on the lower lip that was examined, the number of blue spots occurring as a reaction of iodine and starch on the test tape was counted and was compared among three groups. In addition, the relationship between the histopathological findings and the number of spots was analyzed. RESULTS: The average number of spots in the patients with oral dryness (4.52+/-3.18 [mean +/- SD]) was lower than that in healthy individuals (9.49+/-2.52, P <.01), and that in the patients with Sjögren syndrome (2.14+/-1.35) was the lowest among all groups in the study. Moreover, this reduction in the number of spots in those patients was accompanied by histopathological changes of the minor salivary glands. CONCLUSION: These findings suggest that this simple, noninvasive method can be successfully used for the estimation of the faculty of secretion of saliva from the minor salivary glands. | |
11005210 | Expression and function of X chromosome-linked inhibitor of apoptosis protein in Sjögren' | 2000 Sep | Apoptotic cell death in acinar and ductal epithelial cells is thought to play an important role in the development of salivary gland dysfunction in patients with Sjogren's syndrome (SS). We examined the expression of anti-apoptotic molecules in salivary glands from patients with SS. The labial salivary glands from six human T-cell leukemia virus (HTLV)-I-seronegative and eleven HTLV-I-seropositive SS patients were analyzed by immunohistochemistry. In vitro experiments were performed with a human salivary gland cell line (HSG cells). Immunohistologic analyses revealed that Bcl-2 and Bcl-x were preferentially expressed in salivary infiltrating mononuclear cells more than acinar and ductal epithelial cells. In contrast, strong X chromosome-linked inhibitor of apoptosis protein (XIAP) expression was evident in both acinar and ductal epithelial cells. The pattern of expression of these anti-apoptotic molecules was similar in both HTLV-I-seropositive and HTLV-I -seronegative SS patients. Western blot analysis confirmed expression of XIAP in cultured HSG cells. The expression of XIAP in HSG cells was increased by IL-1beta, TGF-beta1, or IL-10. However, XIAP expression was down-regulated by TNF-alpha, which induced apoptotic cell death of HSG cells with an increase in caspase-3 activity. These effects of TNF-alpha in HSG cells were antagonized by IL-1beta, TGF-beta1, or IL-10. Our results suggest that XIAP is important in regulating apoptotic cell death of acinar and ductal epithelial cells in patients with SS. | |
10765853 | Sjögren's syndrome. | 1999 Oct | Sjögren's syndrome (SS) is a progressive autoimmune rheumatic disorder. Its precise etiology is unknown, although several contributing factors have been identified. One theory is that the condition results from complications related to infection with the Epstein-Barr virus. Primary exposure to or reactivation of Epstein-Barr virus elicits expression of the human leukocyte antigen complex. This is recognized by T lymphocytes (CD 4+) resulting in the release of cytokines (tumor necrosis factor, interleukin-2, interferon-gamma, and others). A genetic marker specific for Sjögren's syndrome, HLA-DR4, has been identified. According to the World Health Organization, the prevalence of Sjögren's syndrome is unknown. A recent epidemiologic study in Sweden estimated the prevalence in the adult population to be 2.7%. In the United States, 10 years ago, the number of patients with Sjögren's syndrome was thought to be fewer than 100,000. This number today is estimated to be more than 1 million. Sjögren's syndrome has been reported in nearly every major country of the world, and the geographic distribution of cases appears to be relatively uniform. Sjögren's syndrome typically affects women (90%) during the fourth or fifth decade of life. Isolated cases of Sjögren's syndrome in children have been reported. | |
9951023 | [Sjögren syndrome and subacute demyelinating polyradiculopathy: an unusual association]. | 1998 Dec | INTRODUCTION: Sjögren's syndrome is a chronic inflammatory condition of unknown aetiology and autoimmune pathology. The defining feature is the dry syndrome, expressed as xerophthalmia and xerostomia. Extra-glandular involvement at many other levels may also occur. Neurological involvement is not unusual. The peripheral nervous system is most frequently involved, and a predominantly sensitive symmetrical distal polyneuropathy may be the first sign of the condition. Other patterns of peripheral involvement are also associated with the syndrome. We present a case of subacute demyelinating polyradiculopathy associated with primary Sjögren's syndrome. CLINICAL CASE: A 28 year old woman with dry syndrome presented with paraesthesia in her hands and feet, distal weakness, which had progressed proximally in the muscles of her arms and legs, and bilateral facial weakness. The condition progressed for eight weeks. When complementary tests were done, alterations typical of this condition (FR, ANA, anti-Ro and anti-La) were seen and also others typical of the dry syndrome (Schirmer's test). Therefore, in view of these findings and the clinical features, after other conditions had been ruled out, a diagnosis of primary Sjögren's syndrome was made. The type of neuropathy was determined by the clinical features, electromyography and CSF findings. Treatment with corticosteroids gave good results. CONCLUSIONS: Demyelinating polyradiculopathy is a form of peripheral nervous system involvement which is rarely seen in this disorder. In the differential diagnosis Sjögren's syndrome should be considered, an orientative history taken, autoantibodies determined and an ophthalmological examination made. | |
9775500 | Successful treatment of Sjögren's syndrome with cyclophosphamide pulse therapy: report of | 1998 Jul | The treatment of Sjögren's syndrome (SS) is very controversial, though several therapeutic regimens have been proposed. Cyclophosphamide pulse therapy has been widely used in many disease entities. However, reports concerning its clinical application in SS were very rare. We report a 17-year-old girl presenting with lupus nephritis and SS, which was refractory to corticosteroid therapy but successfully treated with cyclophosphamide pulse therapy. The improvement of clinical features was confirmed by Schirmer's test and minor salivary gland biopsy. | |
9588268 | Adult-onset Still's disease in an oriental population: manifestations, course and outcome | 1998 Jan | This retrospective descriptive study aims to characterise and compare the clinical manifestations, course and outcome of 16 Oriental patients with adult-onset Still's disease diagnosed in the last 4 years with published data based on Western populations and another Oriental (Japanese) series. Like the Japanese, we found a female preponderance, an older age at onset, and fewer patients with abdominal pain, myalgia, sore throat and serositis compared to the Western series. A longer delay in diagnosis occurred in patients lacking either arthritis or rash at presentation. Most patients had mild hyponatraemia and 2 patients had overt syndrome of inappropriate anti-diuretic hormone secretion. All patients showed a dissociation of elevated aldolase with normal to low creatine kinase levels. Over 50% relapsed within a year from diagnosis and needed slow-acting anti-rheumatic drugs as steroid-sparing agents. Two were given intravenous pulse cyclophosphamide therapy for progressive pneumonitis. Outcome was generally good with minimal functional impairment and no mortality. | |
11480009 | [Oral candidiasis in Sjögren's syndrome: prevalence, clinical features and treatment]. | 1997 Aug | The clinical feature of 20 cases with oral candidiasis in Sjögren's syndrome (SS) were reported, and the treatment effect by topical nystatin smearing, 2% sodium bicarbonate solution rinsing, and transfer factor injecting for about 2 months were analysed. The results showed that the diagnostic criterion of oral candidiasis in SS included two aspects: the SS changes confirmed by labial gland biopsy and candidal hyphae and spores found in a smear. The results indicated that the comprehensive treatments were proved to be effective for oral candidiasis in SS. | |
9190001 | Sjögren's syndrome in patients with newly diagnosed untreated non-Hodgkin's lymphoma. | 1997 May | The purpose of the study was to detect cases of Sjögren's syndrome among newly diagnosed untreated patients with non-Hodgkin's lymphoma and, furthermore, to identify in such cases clinical and serologic features known to occur more frequently in Sjögren's syndrome patients who evolve into lymphoma. Accordingly, thirty-three cases of newly diagnosed non-Hodgkin's lymphoma, prior to any treatment administration, were thoroughly studied for evidence of Sjögren's syndrome. Immunophenotyping for T and B cells and kappa and lambda light chains was concomitantly performed on both lymphomatous tissues and minor salivary glands. There were 5 patients with T cell and 28 with B cell lymphoma of various histologic subtypes and grades. Two of the latter (7.1%) had a positive for Sjögren's syndrome minor labial salivary gland biopsy, positive responses to the specific questionnaires for both eye and mouth dryness and abnormal Schirmer's and rose Bengal eye tests, substantiating the diagnosis of Sjögren's syndrome. Both were male with lung and stomach non-Hodgkin's lymphoma respectively, enlargement of the lacrimal glands, monoclonal gammapathy of the IgM kappa type and, one of them had high titer and of fine speckled pattern positive antinuclear antibodies and anti-Ro(SSA) and anti-La(SSB) antibodies in his serum. A monotypic infiltrate with kappa light chain restriction, identical to that in the lymphomatous tissue of these two patients, was present in their minor salivary gland biopsy as well. Such a finding was not encountered in any of the remaining patients. Although our sample is relatively small, our results confirm the relationship between Sjögren's syndrome and non-Hodgkin's lymphoma, looked at from the opposite direction. Obviously, studies involving larger populations would be more definitive, regarding the issue of what percentage of this lymphoma patients originates from Sjögren's syndrome. |
