9818669 | Musculoskeletal manifestations, pain, and quality of life in Persian Gulf War veterans ref | 1998 Nov | OBJECTIVE: Pain in the joints and other areas has been a frequent complaint among veterans of Operation Desert Storm who are experiencing unexplained illness. We characterized the rheumatic manifestations of a group of veterans of the Persian Gulf War who were referred to a rheumatology clinic. METHODS: Consecutive South Texas veterans of the Persian Gulf War who were referred for evaluation of rheumatic manifestations underwent a comprehensive evaluation of their musculoskeletal symptoms, pain, and health related quality of life. RESULTS: Of 928 veterans evaluated in a screening clinic for unexplained symptoms, 145 had rheumatic manifestations (15.6%) and were referred to a rheumatology clinic. The most common diagnosis was fibromyalgia, present in 49 patients (33.8%), followed by various soft tissue problems in 25 (17.2%), nonspecific arthralgias in 14 (9.6%), and clinical or radiographic osteoarthritis in 16 (11.0%). In 39 patients (26.9%), no symptoms were present at the time of the evaluation, a careful musculoskeletal examination and laboratory tests were normal, and no diagnosis was possible. Two patients had Reiter's syndrome. Four had a positive rheumatoid factor and 3 had antinuclear antibodies, but none of these had clinical evidence of rheumatoid arthritis or systemic lupus erythematosus. Pain was present in nearly all patients and was widely distributed, with no body area spared in this group of patients. The most frequent painful areas were the knees in > 65%, the lower back in > 60%, the shoulders in 50%, and the hands and wrists in 35%. Widespread body pain was present in 65.1% of the veterans. Average values of all 8 scales measured by the SF-36 health survey were below the 25th percentile of published national norms, with pain and the number of nonarticular rheumatic symptoms explaining most of the decreased health related quality of life in the veterans we evaluated. CONCLUSION: No specific rheumatic diagnosis is characteristic of Gulf War veterans with unexplained illness referred to a rheumatology clinic. However, pain is common and widespread in these patients, and their health related quality of life is poor. Further research is necessary to determine the cause of the symptoms of veterans of the Gulf War. | |
9222707 | Effect of gastric mucosal protection in nonrheumatoid patients with short-term nonsteroida | 1997 May | BACKGROUND/AIMS: Since nonsteroidal anti-inflammatory drugs (NSAIDs) are known to cause gastrointestinal mucosal injury, concurrent administration of gastric protective agents in patients with rheumatoid disorders is often recommended. The present study was designed to determine the possible benefit of sucralfate, a gastric protective agent in patients receiving short-term therapy with NSAIDs for conditions other than rheumatoid arthritis. METHODOLOGY: In nineteen general practitioners offices a total of 208 patients were studied. Patients received either sucralfate suspension (2 x 2 g/day) or no additional medicine while being put on NSAIDs for a mean of 9 days. RESULTS: Forty patients (39%) in the sucralfate group and 71 (68%) in the control group developed gastrointestinal symptoms (p < 0.05). In the control group six patients (6%) had gastrointestinal hemorrhage and 2 patients (2%) experienced perforation of a duodenal ulcer. Gastrointestinal hemorrhage and perforation were not observed in the sucralfate group. Short-term NSAID use in nonrheumatoid patients carries a higher risk for symptoms and complications in patients that are 40 years old and above. These risk are even more pronounced in patients of 60 years of age or above, in patients with a history of peptic ulcer disease, in smokers, in patients with concomitant disease and concomitant steroid use, and with the use of diclofenac. The mean age of patients with gastrointestinal hemorrhage was 65 years. Both patients that suffered perforation of a duodenal ulcer were young (35 and 42 years) and had a history of duodenal ulcer disease. CONCLUSION: Gastric protection with sucralfate reduces the frequency of both symptoms and complications in nonrheumatoid patients receiving short-term therapy with NSAIDs. | |
11585452 | Selective inhibition of ICAM-1 and E-selectin expression in human endothelial cells. 2. Ar | 2001 Oct 11 | The elevated expression of cell adhesion molecules (CAMs) on the lumenal surface of vascular endothelial cells is a critical early event in the complex inflammatory process. The adhesive interactions of these CAMs that include E-selectin, ICAM-1, and VCAM-1 with their counter-receptors on leukocytes, such as integrins of the alpha(L)beta(2) family, result in migration of the leukocytes to the site of inflammation and cause tissue injury. Pharmaceutical agents that could suppress the induced expression of one or more of these cell adhesion molecules would provide a novel mechanism to attenuate the inflammatory responses associated with chronic inflammatory diseases. A-205804 (1), a potent and selective inhibitor of the induced expression of E-selectin and ICAM-1 over VCAM-1, was further modified with emphasis at the C-4 and C-2 positions to identify a more potent drug candidate with a good pharmacokinetic profile and physical properties. Replacement of the C-4 sulfur linkage in 1 with an oxygen atom eliminated one of the two major metabolites for this lead molecule. The para-position of the 4-phenoxy group of the thieno[2,3-c]pyridine lead is found to be very critical for a higher in vitro potency and selectivity of E-selectin and ICAM-1 over VCAM-1 expression. This position is presumably close to the solvent-accessible region of the target protein-inhibitor complex. An attempt to install a water-solubilizing group at the para-position of the phenoxy group to increase the aqueous solubility of this lead series through various linkages failed to provide an ideal inhibitor. Only small substituents such as fluorine are tolerated at the meta- and ortho-positions of the 4-phenoxy to retain a good in vitro potency. Bromo, trifluoromethyl, pyrazol-1-yl, and imidazol-1-yl are among the better substituents at the para-position. With fine-tuning at the C-2 position we discovered a series of very potent (IC(50) < 5 nM for ICAM-1) and selective (>200-fold vs VCAM-1) inhibitors with a good pharmacokinetic profile. Demonstrated efficacy in a rat rheumatoid arthritis model and in a mice asthma model with selected compounds is also reported. | |
11062606 | Specificity of T cells in synovial fluid: high frequencies of CD8(+) T cells that are spec | 2000 | INTRODUCTION: Epstein-Barr virus (EBV) is transmitted orally, replicates in the oropharynx and establishes life-long latency in human B lymphocytes. T-cell responses to latent and lytic/replicative cycle proteins are readily detectable in peripheral blood from healthy EBV-seropositive individuals. EBV has also been detected within synovial tissue, and T-cell responses to EBV lytic proteins have been reported in synovial fluid from a patient with rheumatoid arthritis (RA). This raises the question regarding whether T cells specific for certain viruses might be present at high frequencies within synovial fluid and whether such T cells might be activated or able to secrete cytokines. If so, they might play a 'bystander' role in the pathogenesis of inflammatory joint disease. OBJECTIVES: To quantify and characterize T cells that are specific for epitopes from EBV, cytomegalovirus (CMV) and influenza in peripheral blood and synovial fluid from patients with arthritis. METHODS: Peripheral blood mononuclear cells (PBMCs) and synovial fluid mononuclear cells (SFMCs) were obtained from patients with inflammatory arthritis (including those with RA, osteoarthritis, psoriatic arthritis and reactive arthritis). Samples from human leucocyte antigen (HLA)-A2-positive donors were stained with fluorescent-labelled tetramers of HLA-A2 complexed with the GLCTLVAML peptide epitope from the EBV lytic cycle protein BMLF1, the GILGFVFTL peptide epitope from the influenza A matrix protein, or the NLVPMVATV epitope from the CMV pp65 protein. Samples from HLA-B8-positive donors were stained with fluorescent-labelled tetramers of HLA-B8 complexed with the RAKFKQLL peptide epitope from the EBV lytic protein BZLF1 or the FLRGRAYGL peptide epitope from the EBV latent protein EBNA3A. All samples were costained with an antibody specific for CD8. CD4+ T cells were not analyzed. Selected samples were costained with antibodies specific for cell-surface glycoproteins, in order to determine the phenotype of the T cells within the joint and the periphery. Functional assays to detect release of IFN- or tumour necrosis factor (TNF)- were also performed on some samples. RESULTS: The first group of 15 patients included 10 patients with RA, one patient with reactive arthritis, one patient with psoriatic arthritis and three patients with osteoarthritis. Of these, 11 were HLA-A2 positive and five were HLA-B8 positive. We used HLA-peptide tetrameric complexes to analyze the frequency of EBV-specific T cells in PBMCs and SFMCs (Figs 1 and 2). Clear enrichment of CD8+ T cells specific for epitopes from the EBV lytic cycle proteins was seen within synovial fluid from almost all donors studied, including patients with psoriatic arthritis and osteoarthritis and those with RA. In donor RhA6, 9.5% of CD8+ SFMCs were specific for the HLA-A2 restricted GLCTLVAML epitope, compared with 0.5% of CD8+ PBMCs. Likewise in a donor with osteoarthritis (NR4), 15.5% of CD8+ SFMCs were specific for the HLA-B8-restricted RAKFKQLL epitope, compared with 0.4% of CD8+ PBMCs. In contrast, we did not find enrichment of T cells specific for the HLA-B8-restricted FLRGRAYGL epitope (from the latent protein EBNA3A) within SFMCs compared with PBMCs in any donors. In selected individuals we performed ELISpot assays to detect IFN- secreted by SFMCs and PBMCs after a short incubation in vitro with peptide epitopes from EBV lytic proteins. These assays confirmed enrichment of T cells specific for epitopes from EBV lytic proteins within synovial fluid and showed that subpopulations of these cells were able to secrete proinflammatory cytokines after short-term stimulation. We used a HLA-A2/GILGFVFTL tetramer to stain PBMCs and SFMCs from six HLA-A2-positive patients. The proportion of T cells specific for this influenza epitope was low (<0.2%) in all donors studied, and we did not find any enrichment within SFMCs. We had access to SFMCs only from a second group of four HLA-A2-positive patients with RA. A tetramer of HLA-A2 complexed to the NLVPMVATV epitope from the CMV pp65 protein reacted with subpopulations of CD8+ SFMCs in all four donors, with frequencies of 0.2, 0.5, 2.3 and 13.9%. SFMCs from all four donors secreted TNF after short-term incubation with COS cells transfected with HLA-A2 and pp65 complementary DNA. We analyzed the phenotype of virus-specific cells within PBMCs and SFMCs in three donors. The SFMC virus-specific T cells were more highly activated than those in PBMCs, as evidenced by expression of high levels of CD69 and HLA-DR. A greater proportion of SFMCs were CD38+, CD62L low, CD45RO bright, CD45RA dim, CD57+ and CD28- when compared with PBMCs. DISCUSSION: This work shows that T cells specific for certain epitopes from viral proteins are present at very high frequencies (up to 15.5% of CD8+ T cells) within SFMCs taken from patients with inflammatory joint disease. This enrichment does not reflect a generalized enrichment for the 'memory pool' of T cells; we did not find enrichment of T cells specific for the GILGFVFTL epitope from influenza A or for the FLRGRAYGL epitope from the EBV latent protein EBNA3A, whereas we found clear enrichment of T cells specific for the GLCTLVAML epitope from the EBV lytic protein BMLF1 and for the RAKFKQLL epitope from the EBV lytic protein BZLF1. The enrichment might reflect preferential recruitment of subpopulations of virus-specific T cells, perhaps based on expression of selectins, chemokine receptors or integrins. Alternatively, T cells specific for certain viral epitopes may be stimulated to proliferate within the joint, by viral antigens themselves or by cross-reactive self-antigens. Finally, it is theoretically possible that subpopulations of T cells within the joint are preferentially protected from apoptotic cell death. Whatever the explanation, the virus-specific T cells are present at high frequency, are activated and are able to secrete proinflammatory cytokines. They could potentially interact with synoviocytes and contribute to the maintenance of inflammation within joints in many different forms of inflammatory arthritis. | |
11138341 | Otitis externa sicca/fibrotising external otitis (FEO) as a complication of Sjögren's syn | 2000 Nov | Sjögren's syndrome (SS) is a condition characterized by sicca symptoms and by autoimmune features. We describe two SS patients with otitis externa fibroticans/sicca. One of these 2 patients developed a lesion of the tympanic membrane making it necessary to perform a tympantomy and meatoplasty. Our findings suggest firstly that the epithelial cell-mediated secretion of lamellar bodies and the production of the permeability barrier are defective in SS. Secondly, local moisturing and/or topical corticosteroid treatment in SS patients with sicca symptoms in the auditory canal could help to avoid reconstructive surgical treatment. | |
11100668 | [G-CSF versus GM-CSF in the treatment of neutropenia in a patient with Felty's syndrome on | 2000 Sep | We describe a patient with Felty's syndrome and chronic renal failure due to secondary amyloidosis in a periodic haemodialysis programme, who was successfully treated for neutropenia with sequential administration of colony-stimulating factors: granulocyte colony-stimulating factor and granulocyte macrophage colony-stimulating factor. | |
10783055 | Severe thrombocytopenia caused by digitoxin intoxication in a patient with heart failure a | 2000 Apr | Congestive heart failure (CHF) related to Sjögren's syndrome is extremely rare. This report concerns a patient who presented with CHF and severe thrombocytopenia (5,000/microl). Serum concentrations of K, Mg and digitoxin were 3.2mmol/L, 1.4mg/L and 57.2ng/ml, respectively. Digitoxin intoxication was evident, seemingly evoked by hypokalemia, hypomagnesemia, hepatorenal dysfunction and hypothyroidism. The severe thrombocytopenia was considered to have been caused by this intoxication, as it disappeared soon after the digitoxin was discontinued and potassium was supplemented. | |
10515244 | A combination of autoimmune hepatitis, sensory-dominant peripheral neuropathy, and primary | 1999 | Although autoimmune hepatitis and sensory-dominant neuropathy have been known to independently accompany primary Sjögren's syndrome, the combination of all these conditions in the same patient has not been described. We report the case of a woman who initially suffered from autoimmune hepatitis and later was diagnosed with primary Sjogren's syndrome upon the development of sensory-dominant neuropathy. In this patient, autoimmune hepatitis preceded neuropathy by one year. All of the diagnoses were confirmed by histological examinations of the liver, sural nerve, and minor salivary gland. Her autoimmune hepatitis was relieved with conservative treatment, and her sensory-dominant neuropathy was alleviated by prednisolone therapy. Our case indicated that the multiple organ involvement, especially that in the liver and peripheral nerves, should be taken into account in the course of primary Sjögren's syndrome. | |
10414849 | The flow rate and composition of human labial gland saliva. | 1999 May | Since the flow rate of saliva from human labial salivary glands has usually been measured as the secretion from an area of labial mucosa as 0.05-4.8 microl/cm2/min. The only data for single glands gives a comparable figure of 0.1 microl/min/gland. There is no consensus on the effects of gustatory stimulation, gender or ageing, although most reports suggest that flow rate is not related to gender and ageing up to age 60. The main differences in composition between labial gland saliva and that from the major glands are the higher and variable sodium concentration, the very low phosphate and hydrogen carbonate concentrations, and the higher protein concentration despite low concentrations of amylase. The concentrations of IgA and blood group substances are notably higher in labial gland saliva. In Sjogren's syndrome and cystic fibrosis flow rates are decreased. Low rates of flow have been associated with a higher incidence of dental caries. | |
9532000 | Characterization of the inflammatory infiltrate in autoimmune cholangitis. A morphological | 1998 Mar | Autoimmune cholangitis (AIC) is characterised by clinical and/or laboratory features of cholestasis, the presence of antinuclear antibodies and the lack of antimitochondrial antibodies. Histologically, changes largely identical to those found in primary biliary cirrhosis (PBC) are typically found. It is not possible to differentiate between AIC and PBC on conventional morphological grounds, and we therefore wished to find whether there is a difference between these entities in the composition of the inflammatory infiltrate leading to bile duct destruction. In liver biopsies from ten patients with confirmed AIC and ten patients with PBC the inflammatory infiltrate was characterised with antibodies against CD 3, OPD 4 CD 8, GB 7, L 26, CD 56 and CD 57. In AIC, T cells were predominant in the portal inflammatory infiltrate in nine cases. Granzyme B-positive activated cytolytic T lymphocytes were found in the bile duct epithelium in five cases. All these five cases showed inflammatory bile duct destruction. No significant differences between the immunohistochemical findings in AIC and in PBC were found. We suggest that AIC is a subgroup of PBC, antimitochondrial antibody-negative type. | |
9275871 | Primary Sjögren's syndrome and associated lung disease: CT findings in 50 patients. | 1997 Sep | OBJECTIVE: We prospectively evaluated the high-resolution CT findings in 50 nonsmoking patients with proven primary Sjögren's syndrome. CONCLUSION: High-resolution CT is a sensitive technique in assessing pulmonary involvement in patients with primary Sjögren's syndrome. Interstitial lung disease and bronchiolar inflammatory changes are common abnormal findings seen on CT scans in primary Sjögren's syndrome. | |
9188924 | Anti-inflammatory drugs do not alleviate bronchial hyperreactivity in Sjögren's syndrome. | 1997 Apr | Bronchial hyperreactivity (BHR) is found in Sjögren's syndrome, as in a number of other conditions such as asthma. BHR associated with asthma can be effectively treated with corticosteroids or sodium cromoglycate. We treated 19 Sjögren's syndrome patients with BHR with inhaled budesonide and inhaled cromoglycate for 6 weeks each. None of the treatment had any significant effect on symptoms of hyperreactivity or lung function. There was no effect on BHR measured as methacholine reactivity. Primary Sjögren's syndrome is a disease with inflammation not only in the salivary and lacrimal glands but also in the pulmonary alveoli and the bronchi. The main inflammatory cell is the lymphocyte, whereas, in the bronchi in asthma, the eosinophil granulocyte is the characteristic inflammatory cell. The cause of the discrepancy with regard to treatability of BHR in asthma and in Sjögren's syndrome is not known. Possibly not all BHR is caused by inflammation. There is not a perfect correlation between inflammation and hyperreactivity even in asthma. Even in the bronchial inflammation and the asthma symptoms are easy to treat with anti-inflammatory medicines, a considerable component of BHR usually still remains, as measured with methacholine or histamine. | |
9127376 | Prevalence of periodontal disease in patients with Sjögren's syndrome. | 1997 Apr | The periodontal status of 25 patients with Sjögren's syndrome was compared with that of an age-, sex-, and race-matched healthy controls. Clinical evaluation included determination of number of teeth, decayed/missing/filled surfaces, probing pocket depth, clinical attachment level, plaque index, gingival index, bleeding on probing, and measurement of alveolar bone level (examined with radiography). Results of the study suggest that patients with Sjögren's syndrome have a significantly higher plaque index score (p < 0.005), higher decayed/missing/filled surfaces scores (p < 0.05), increased alveolar bone loss (p < 0.05), deeper clinical attachment level (p < 0.05), and increased cementoenamel junction-alveolar bone crest distance (p < 0.005). Although no significant difference was found in the number of cases of "established periodontitis" between the Sjögren's syndrome and controls, odds ratio analysis suggests that patients with Sjögren's syndrome are at 2.2 times higher risk of having adult periodontitis than healthy controls. | |
9093796 | Elevation of serum soluble intercellular adhesion molecule-1 (sICAM-1) and beta-2-microglo | 1997 Mar | Sjögren's syndrome is a chronic inflammatory disease which is believed to be immunologically mediated. It is marked by inflammation and destruction of the salivary glands and lacrimal glands. We have found significantly higher serum levels of sICAM-1 and beta-2-microglobulin in both primary Sjögren's syndrome patients (429.1 +/- 114.33 ng/ml, 4.4 +/- 1.5 ug/ml resp.) and secondary Sjögren's syndrome patients (424 +/- 140.73 ng/ml, 4.4 +/- 2.67 ug/ml resp.) in comparison with healthy controls (189.1 +/- 42.34 ng/ml, 1.3 +/- 0.38 ug/ml resp.). The serum level of beta-2-microglobulin was significantly correlated with the serum level of sICAM-1 in secondary Sjögren's syndrome patients' group. | |
9759146 | Obstetrical and neonatal outcome in pregnant patients with rheumatic disease. | 1998 | Possible associations between inflammatory rheumatic and connective tissue disease and adverse pregnancy outcome were assessed by using the Medical Birth Registry of Norway during the years 1967-95. All women with rheumatic disease were compared to women without such disease. Data on pregnancy outcome and deliveries were analyzed after adjustment for possible confounding factors. Women with rheumatic disease had significantly higher rates of preeclampsia, premature delivery and cesarean section as well a significantly increased relative risk of SGA children in all diagnostic groups in 1967-95. These findings emphasize the importance of close monitoring of pregnancy and delivery not only in patients with connective tissue disease, but also in patients with other inflammatory rheumatic disease. | |
11669158 | Iron saturation of serum ferritin in patients with adult onset Still's disease. | 2001 Oct | OBJECTIVE: Patients with Still's disease show a prominent acute phase reaction. Our hypothesis is that under these circumstances the iron uptake of ferritin will not keep pace with its synthesis, and is therefore not a valid reflection of the iron status in these patients. METHODS: Previously we developed a method to measure the iron content of ferritin; we investigated the usefulness of this method to establish the iron status of patients with anemia of inflammation. RESULTS: In 9 patients with adult onset Still's disease (AOSD) we observed high ferritin concentrations and measured the iron saturation of ferritin. The mean value of saturation was 9.1%, while saturation in the healthy control group was 17.8%, a statistically significant difference (p < 0.005). Soluble transferrin receptor concentrations indicated a functional iron deficiency. CONCLUSION: We conclude that the acute phase ferritin in patients with AOSD contains less iron in comparison to ferritin in healthy controls. We suggest that soluble transferrin receptor is the method of choice in estimating the iron status of patients with an acute phase reaction. | |
11240866 | Salivary calprotectin levels are raised in patients with oral candidiasis or Sjögren's sy | 2001 Apr | Calprotectin levels were determined in whole saliva from patients predisposed to oral candidiasis due to HIV infection or Sjögren's syndrome and from patients with candidiasis associated with various oral disorders (e.g. lichen planus, oral ulceration). Mean calprotectin levels were higher in whole saliva (2 microgram/ml) than in parotid saliva (0.3 microgram/ml). Oral candidiasis was associated with raised whole saliva calprotectin levels in all groups studied. HIV infection was associated with lower levels of salivary calprotectin, in the presence of high or low salivary Candida counts, although CD4+ lymphocyte counts did not significantly correlate with calprotectin concentrations. Calprotectin levels were elevated in saliva from Sjögren's syndrome patients with oral candidiasis, consistent with mucosal transudation of calprotectin from inflamed mucosa and limited dilution due to decreased salivary flow rates. This study indicates that oral candidiasis is associated with raised calprotectin levels secondary to mucosal inflammation, but that diminution of this candidacidal factor due to HIV infection may be a predisposing factor in the aetiology of oral candidiasis. | |
10614168 | [Cytomegalovirus infection associated with immunosuppressive therapy in collagen vascular | 1999 Oct | OBJECTIVE: We investigated the frequency of cytomegalovirus (CMV) infection during immunosuppressive therapy in collagen vascular disease by using CMV antigenemia assay. METHODS: CMV antigenemia in fifteen patients with collagen vascular disease were analyzed before and one month after immunosuppressive therapy with more than 30 mg/day of prednisolone. RESULTS: CMV antigenemia were detected in 9 patients (60%), however no CMV antigenemia detected in all patients before treatment. In 7 of 9 patients CMV infection occurred such as fever, leucocytopenia, thrombocytopenia, liver injury, interstitial pneumonia. In 2 patients of polymyositis/dermatomyositis, creatine phosphokinase (CPK) levels which had decreased once just after treatment started, elevated again although initial dose of prednisolone continued. After ganciclovir administration because of the positive results of CMV antigenemia, elevated CPK levels were normalized immediately. CONCLUSION: Our results showed that CMV infection occurred with high frequency during immunosuppressive therapy, and might mimic the exacerbation of collagen vascular disease. It is important to differentiate CMV infection from increased activity of collagen vascular disease during the treatment. | |
10695409 | [A case of Sjögren's syndrome with retrobulbar optic neuritis and cutaneous vasculitis]. | 1999 Dec | A 52-year-old woman, diagnosed as having Sjögren's syndrome by parotid sialography and lip biopsy after a two years history of recurrent purpuric rashes on her lower extremities, was admitted to our hospital because of visual disturbance in March 1998. On presentation at the department of ophthalmology, her right visual acuity was light perception, and laboratory findings showed elevated levels of antinuclear antibody and anti-Ro/SS-A and anti-La/SS-B antibodies. Cerebrospinal fluid analysis showed mild pleocytosis and elevated levels of total protein and Q-albumin. The IgG-index was within normal level and no oligoclonal band was found. Magnetic resonance imaging showed increased signal intensity at the right optic nerve. After treatment with m-PSL pulse therapy, her visual acuity recovered to 0.08. When prednisolone was gradually tapered to the dose of 30 mg per day, she was transferred to our department because of high grade fever and pancytopenia. She also suffered from palpable purpura in her extremities extending the trunk, whose pathological diagnosis was leukocytoclastic vasculitis. The immunohistochemical examination showed depositions of IgG and C1q. After two additional cycles of mPSL pulse therapies, clinical improvement was achieved. The titers of von Willebrand factor and thrombomodulin correlated with her clinical improvement. Patients with Sjögren's syndrome can develop extra-grandular complications, including neurologic and cutaneus diseases, it is important to understand the role of SS-A-B antibodies in the immunopathogenesis of Sjögren's syndrome. | |
10673783 | Long-term follow-up of patients treated with acupuncture for xerostomia and the influence | 2000 Jan | OBJECTIVE: To determine the long-term effects of acupuncture in patients with xerostomia of different etiologies and the influence of additional treatment. DESIGN: Retrospective study. SUBJECTS: Seventy patients, between the ages of 33 and 82, with xerostomia due to primary and secondary Sjögren's syndrome, irradiation and other causes were included. The median duration of xerostomia was 32 months. METHODS: Salivary flow rates (SFR) for whole unstimulated and stimulated saliva were used as indicators of effects of treatment. Data from 67/70 patients were analyzed 6 months following a baseline course of 24 acupuncture treatments using two-way ANOVA. Patients data up to 3 years were also compared by those who chose to receive additional acupuncture treatment vs those who did not. These data were analyzed descriptively. RESULTS: Statistically significant differences in unstimulated and stimulated salivary flow rates (P < 0.01) were found in all etiological groups after 24 acupuncture treatments and up to 6 months follow-up compared to baseline. Three years observation of these patients showed that patients receiving additional acupuncture treatment had a consistently higher median SFR in both unstimulated and stimulated saliva compared to patients who chose not to continue acupuncture. The upper limits of the interquartile range were also higher. CONCLUSIONS: This study shows that acupuncture treatment results in statistically significant improvements in SFR in patients with xerostomia up to 6 months. It suggests that additional acupuncture therapy can maintain this improvement in SFR for up to 3 years. |
