17828352 Conventional therapy of psoriatic arthritis: evidence-based review. 2007 Psoriatic arthritis is a heterogeneous condition, the pattern of which is determined by any combination of pathology affecting peripheral joints, the enthesis and the spine. There is a paucity of evidence for most of the conventional agents used to treat psoriatic arthritis, with many of them being used on the basis of experience in rheumatoid arthritis. Herein, we summarise the evidence compiled relating to effectiveness of treatment for various manifestation of PsA. For those patients with progressive forms of arthritis who may benefit from intervention of newer biological therapies, the continued use of conventional therapy needs ever increasing scrutiny.
17661048 Abundant expression of tetraspanin CD9 in activated osteoclasts in ovariectomy-induced ost 2008 Jan Tetraspanin CD9 has been shown to be critically involved in multinucleation and cell fusion during osteoclastogenesis, however, its in vivo pathophysiological role in bone-resorbing disorders such as osteoporosis and rheumatoid arthritis, has not been elucidated. To investigate the involvement of tetraspanin CD9 in bone destruction in such diseases, we examined the expression and distribution of tetraspanin CD9 using murine experimental models of osteoporosis and arthritis. In results, CD9 protein is abundantly expressed on the activated osteoclasts in the bone tissues whose trabeculae are severely reduced in ovariectomy-induced osteoporosis. The expression of CD9 is also detected at the sites of bone erosion in arthritic lesions of collagen-induced arthritis (CIA), where tartate-resistant acid phosphatase (TRAP) staining-positive activated osteoclasts are present. These data suggest that tetraspanin CD9 play important roles in bone destructions in osteoporosis and arthritis, and therefore, functional alterations of tetraspanin CD9 may have therapeutic potential in such bone-resorptive disorders.
18203316 Ultrasonography of salivary glands -- a highly specific imaging procedure for diagnosis of 2008 Feb OBJECTIVE: To verify ultrasonographic criteria for examination of the major salivary glands in diagnosis of primary and secondary Sjögren's syndrome (SS). METHODS: Three hundred sixteen consecutive patients with rheumatic diseases were selected according to the European Consensus Study Group diagnostic criteria for SS. Fifty-seven had primary SS, 33 had secondary SS, 78 had Sicca symptoms, and 148 patients served as asymptomatic controls. This cohort was analyzed for size and parenchymal echogenicity of the major salivary glands by ultrasonography. RESULTS: Evident parenchymal inhomogenicity in 2 or more major salivary glands was detected by ultrasonography in patients with primary and secondary SS with a sensitivity of 63.1% and 63.6%, respectively. The specificity of this imaging approach in our cohort was 98.7%. The volume of submandibular glands was reduced in patients with primary and secondary SS by about 30% compared to patients with sicca symptoms and asymptomatic controls. In receiver-operating characteristic (ROC) curve analysis, the detection of reduced volumes of both submandibular glands in patients with primary and secondary SS had a specificity of 93% and a sensitivity of 48% at the cutoff point of 3.0 ml. Of note, the volume of the parotid glands did not differ between the groups of patients. In patients with primary SS, parenchymal inhomogenicity of the salivary glands was strongly associated with positivity for anti-Ro and/or anti-La antibodies. CONCLUSION: Ultrasonographic detection of parenchymal inhomogenicity of the major salivary glands and observation of reduced volume of the submandibular glands resulted in high specificities for diagnosis of primary and secondary SS. The data indicate that ultrasonography of major salivary glands is a noninvasive imaging procedure with high diagnostic value for the diagnosis of primary and secondary SS.
17239152 Ulcerative lichen planus associated with Sjögren's syndrome. 2007 Feb Ulcerative lichen planus is a rare variant of lichen planus that is characterized by ulcerations of the feet and toes that are accompanied by toenail loss. However, the nail, oral mucosa, genital mucosa and the scalp are also sometimes affected by ulcerative lichen planus. Several authors have drawn attention to the association of ulcerative lichen planus and autoimmune diseases. We report a patient who had ulcerative lichen planus, with ulcerative erythema on the soles and palms, nail dystrophy and oral lesions, as well as Sjögren's syndrome; she was successfully treated with etretinate.
18797666 [Correlation between signals and symptoms of dry eye in Sjögren's syndrome patients]. 2008 Jul PURPOSE: To study the correlation between the signals and symptoms of dry eye in Sjögren's syndrome patients. METHODS: We formed the case group with 17 Sjögren's syndrome patients and the control group with 25 normal patients. For evaluation of the symptoms the "Ocular Surface Disease Index (OSDI)" questionnaire was applied to both groups and, after that, all the individuals were submitted to the ocular tests: Schirmer I and II, coloration of the ocular surface with rose bengal, pachymetry and esthesiometry. Spearman's correlation test was used to analyze the correlations between signals and symptoms and Student's t test for independent samples was used for comparison of the averages of the values found by the "Ocular Surface Disease Index (OSDI)" questionnaire and the ocular tests between the patients of the groups. RESULTS: This study had evidenced a weak correlation between "Ocular Surface Disease Index (OSDI)" symptoms and ocular tests, which it indicates that not all the patients who presented exuberant symptoms, showed proportionally modified tests. The cornea sensitivity of the case group was reduced when compared with that of the control group. All the studied parameters in the case group presented significant differences (p<0.05) when compared with the control group. CONCLUSION: There was a weak correlation between Sjögren's syndrome patients' ocular symptoms and signals that indicate the severity of the illness. The variation of cornea sensitivity found in the Sjögren's syndrome patient group may be one of the responsible factors for this weak correlation. All the studied parameters were significantly modified in the Sjögren's syndrome patients group when compared with those found in the control group.
18488390 [The evaluation of chosen cytokines in induction of ocular changes in Sjögren's syndrome 2007 PURPOSE: To evaluate the role of pro-inflammatory cytokines interleukin-8 (IL-8) and interferon-gamma (IFN-gamma) in pathogenesis of Sjogren's syndrome of dry eye (SS--dry eye), and in induction of ocular changes in this disease. MATERIAL AND METHODS: Tear samples were collected from 25 patients with Sjogren's syndrome of dry eye and 33 healthy volunteers. Cytokine levels were determined by ELISA. Ophthalmic examinations, including tests for dry eye, were used to study the ocular surface. The levels of these cytokines in tears and dry eye findings were compared. RESULTS: The tears level of IL-8 and IFN-gamma in SS--dry eye patients were significantly higher than those in controls. We found positive correlation between the tears levels of pro-inflammatory cytokines and dry eye findings (subjective and objective assessments and diagnostic tests). CONCLUSIONS: The elevated level of pro-inflammatory cytokines in tears fluid of patients with Sjogren's syndrome of dry eye may be important factor in the pathogenesis of this disease. Significant correlation between tears level of cytokines and dry eye findings suggest, that these cytokines induce inflammatory changes of ocular surface in Sjogren's syndrome of dry eye.
18478182 Effect of the H2 receptor antagonist nizatidine on xerostomia in patients with primary Sjà 2008 In Sjögren's syndrome (SS), oral dryness (xerostomia) is frequently the most bothersome symptom. An H2 histamine receptor antagonist is often administered to SS patients to treat associated superficial gastritis. The aim of the present study was to assess the ability of nizatidine, an H2 receptor antagonist, to also relieve xerostomia in patients with primary SS. Twenty-seven patients with primary SS were randomly assigned to receive nizatidine (n=14, 300 mg a day) or another H2 blocker, famotidine (n=13, 40 mg a day; control), were followed for eight weeks, and were asked for both subjective and objective assessments of oral dryness using a visual analog scale (VAS; 1-100 mm) and the Saxon's test, respectively. Patients receiving oral nizatidine, but not famotidine, obtained significant objective relief from their xerostomia (Saxon's test; baseline, 0.57 g/2 min; after eight weeks, 0.90 g/2 min, P<0.05). VAS scores indicated that nizatidine also provides mild improvement (20% improvement over baseline) of xerostomia-related clinical conditions, including mouth dryness and difficulty in chewing, tasting and swallowing food. Both drugs were generally well tolerated, without adverse effects. The present preliminary study suggests that nizatidine may represent a new option for the treatment of xerostomia in SS.
17643198 [Vasculitic leg ulcers in primary Sjogren syndrome]. 2008 May Sjögren syndrome is a rare chronic systemic autoimmune disease characterized by progressive dryness of the mucous membranes. There are many variable clinical manifestations. A 40-year-old woman presented with painful leg ulcers refractory to various therapies. She had a history of xerostomia and xerophthalmia for several years. Based on clinical, serologic and histopathologic findings, we diagnosed leg ulcers in primary Sjögren syndrome. Combing immunosuppressive therapy with phase-adapted modern wound-therapy resulted in a complete healing of the ulcers. In the case of clinically atypical leg ulcers, Sjögren syndrome should be considered as a rare differential diagnostic possibility.
17122948 Leukoencephalopathy as a rare complication of hepatitis C infection. 2006 Nov We report the case of a 64-year-old female patient with hepatitis C infection (HCV), who developed Sjögren's disease and sensory peripheral neuropathy. Clinical conditions worsened over three years with central nervous system involvement characterised by transient third cranial nerve paresis and mild selective impairment of attention and memory. Brain magnetic resonance imaging showed diffuse periventricular and lobar white matter hyperintensity. Laboratory findings included mixed cryoglobulinaemia (type II), cryocrit 1.47%, low serum levels of complement C4 and high levels of rheumatoid factor, HCV 1b genotype, high HCV mRNA levels in serum and cerebrospinal fluid. Skin biopsy showed evidence of vasculitis. After one year of plasmapheresis, immunosuppressant therapy and occasional corticosteroid treatment, neurological symptoms improved, skin biopsy changed and inflammation parameters normalised, suggesting that neurological symptoms might be related to the high levels of mixed cryoglobulins.
17000452 Pilocarpine hydrochloride for the treatment of xerostomia in patients with Sjögren's synd 2006 Oct BACKGROUND/PURPOSE: Sjögren's syndrome (SS) is characterized by diminished exocrine secretions with the resultant symptoms of dry mouth and dry eye. As genetic predisposition and ethnicity may alter the effectiveness of drug treatment, evaluation of the efficacy and safety of the secretagogue pilocarpine hydrochloride in the treatment of xerostomia in patients with SS in different populations is needed. METHODS: Forty-four patients with SS were enrolled in this double-blind, placebo-controlled trial. Patients were randomized to receive 5 mg pilocarpine (Salagen) or placebo tablet four times daily for 12 weeks. Global evaluation and subjective responses of patients were assessed by questionnaires with visual analog scales and categorical checkboxes. Saliva production was also measured by modified Saxon's test. RESULTS: Pilocarpine treatment significantly improved global assessment of dry mouth, symptoms associated with dry mouth (mouth comfort, ability to sleep and ability to speak), and saliva production compared to placebo. The drug was well tolerated and the most common adverse effect was sweating (5/23, 21.7%) resulting from the muscarinic agonist action of the drug. No serious drug-related adverse effect was found in this study. CONCLUSION: The results of this study suggest that therapy with 5 mg pilocarpine four times daily is effective, safe and well tolerated for the relief of oral symptoms in patients with SS in Taiwan.
16385504 Dissemination of a Sjögren's syndrome-associated extranodal marginal-zone B cell lymphoma 2006 Jan OBJECTIVE: Both the genesis and outgrowth of extranodal marginal-zone B cell lymphomas (MZLs) of the mucosa-associated lymphoid tissue (MALT) type are generally thought to represent antigen-driven processes. We undertook this study to analyze lymphoma progression and dissemination outside of the MALT-type lesions. METHODS: Histopathologic and Ig heavy- and light-chain variable-region gene (V(H/L)) analyses were performed in sequential tissue samples from a patient with primary Sjögren's syndrome (SS) with glandular (parotid) manifestations and subsequent nodal dissemination of a low-grade MZL. RESULTS: This MZL expressed a CD20+,CD27+,sIgM/kappa+,IgD-,CD5-,CD10-,Bcl-6-,CD23-,p53-,p21-,MDM2- phenotype and mutated V(H)1-69/D2-21/J(H)4alpha-V(kappa)A27/J(kappa)2 Ig rearrangements. Notably, circulating lymphoma cells from the parotid glands occurred transiently in the patient's blood, as detected by single-cell polymerase chain reaction. In addition, 2 minor B cell clones (clones 2 and 3, with V(H)3-07/D3-22/J(H)3b-V(lambda)3L/J(lambda)2/3 and V(H)3-64/D3-03/J(H)2-V(kappa)A19/J(kappa)2 rearrangements, respectively) were also detected in the parotid glands and blood, and 1 of these (clone 2) was also detected in the lymph nodes. Ig V(H/L) analyses revealed ongoing (antigen-driven) mutations of the glandular lymphoma rearrangements, but an invariant mutation pattern of their nodal counterparts. CONCLUSION: These data indicate coexpansion and transient (re)circulation of the lymphoma clone and 2 additional glandular B cell clones in a primary SS-associated extranodal MZL. Combined histologic and molecular features of the nodal lymphoma subclone reflect a process of "follicular colonization" that eventually froze the mutation machinery after accumulation of additional (antigen-driven) Ig V(H/L) mutations.
18465457 Sjögren's syndrome - not just Sicca: renal involvement in Sjögren's syndrome. 2008 May OBJECTIVE: To present a case of severe interstitial nephritis with proteinuria in primary Sjögren's syndrome (pSS) and review the literature regarding renal disease and its management in pSS, aiming to suggest recommendations for treatment. METHODS: A search of MEDLINE (PubMed) was performed for review articles and case reports using the MESH terms: Sjögren syndrome; renal disease; interstitial nephritis (IN); glomerulonephritis (GN). RESULTS: We describe a rare case of pSS presenting with hypokalaemic tetraparesis and proteinuria due to severe IN, successfully treated with high-dose steroids and azathioprine. Reviewing the literature, we identified 180 reported cases of renal involvement in pSS (selected based on the European criteria for pSS), 89 of which underwent renal biopsies revealing IN in 49 cases, GN in 33 samples, and both IN and GN in seven. Eighteen studies reported treatment experience of renal disease in 32 pSS cases. Seventeen patients were treated with corticosteroids and cyclophosphamide, and 15 patients received only steroids with improvement in the majority of cases. CONCLUSION: The present case, as well as the limited number of reports in the literature, suggest that renal involvement, including IN, in pSS may improve with immunosuppressive therapy. Further studies are required to determine indications for and dosages of immunosuppressive treatment in patients with renal involvement of pSS.
17067982 Nailfold videocapillaroscopy in primary Sjögren's syndrome. 2006 Oct Nailfold videocapillaroscopy was performed in 2 groups of subjects: 14 healthy volunteers (C) and 15 patients with primary Sjögren's syndrome (PSS). This was a controlled clinical trial, matched by age and sex. The aims of this study were to evaluate (1) functional capillary density (number of capillaries with flowing red blood cells per mm(2), FCD); (2) capillary red blood cell velocity at rest (RBV), maximum capillary red blood cell velocity (RBV(max)) after 1 minute ischemia, and the time to reach it (TRBV(max)), taking into account the presence or absence of Raynaud's phenomenon (RP) in the analysis; (3) nailfold capillary morphology; and (4) afferent (AFD), apical (APD), and efferent (EFD) capillary diameters. The mean values obtained for controls versus patients, respectively, were (mean +/- SD): FCD (per mm(2)) 8.0 +/-1.6 and 10.1 +/-3.6; RBV (mm/s) 0.9 +/-0.4 and 0.7 +/-0.2; RBV(max) (mm/s) 1.7 +/-0.9 and 1.3 +/-0.3; TRBV(max) (s) 4.5 +/-0.8 and 5.8 +/-1.6 (p=0.02); and TRBV(max) (s) in patients with RP=6.7 +/-1.6 and without RP=5.6 +/-1.6 (p=0.52). The correlation between RBV and RBV(max) for each group, using the Pearson's coefficient, was significant only for the control group (p=0.007), estimated correlation coefficient = 0.68. Controls and patients showed, in the majority of fields examined, normal morphologic patterns of capillaries. The capillary diameters were AFD (mum) 10.8 +/-1.5 and 11.3 +/-1.8; APD (mum) 16.3 +/-2.4 and 16.8 +/-2.9; and EFD (mum) 12.3 +/-1.4 and 13.7 +/-1.9. These results indicate that these patients have longer time to reach RBV(max), suggesting an impairment of the reactive hyperemia response, which could correlate with clinical features of the disease, ie, abnormal macrovascular and microvascular reactivity.
16556275 Dermoscopic patterns of the filiform papillae of the tongue in patients with Sjögren's sy 2006 Feb The purpose of this study was to determine whether there are any differences in the appearance of tongue-surface structure in different kinds of collagen diseases, because red tongue is well known to be a very important feature of suspected Sjögren's syndrome (Sjs). To clarify some features of the filiform papillae on the dorsal surfaces of the tongues of patients with speculated Sjs, we observed a total of 565 individuals with primary Sjs (n = 24, M/F = 0/24), secondary Sjs (n = 16, M/F = 1/15), possible Sjs (n = 96, M/F = 21/75), collagen diseases (CD) (n = 55, M/F = 15/40; 15 SSc, 10 SLE 10, two MCTD, six dermatomyositis, and 22 others), various cutaneous disorders (n = 324, M/F = 118/206), and healthy controls (HC) (n = 50, M/F = 32/18) by using a dermoscope. The average ages of the patients with Sjs, CD (non-Sjs), cutaneous disorders (non-Sjs/CD), and HC were 56.4 14.8, 55.1 116.4, 51.1 121.2, and 37.1 110.6 years of age, respectively. The filiform papillae were classified into four patterns by their structural characteristics: normal papillae (no abnormality with clear cornified tips) (pattern I, n = 162), slightly rounded papillae with unclear cornified tips (pattern II, n = 239), rounded papillae without cornified tips (pattern III, n = 86), and completely flattened papillae (pattern IV, n = 28). Their patterns were reversely related to the volume of salivary fluid (gum test) (P = 0.046) and the degree of furor coating of the tongue (P = 0.051). Pattern IV is predominant in definitive Sjs (primary and secondary Sjs) (n = 15; 53.6%) with positive anti-SS-A or -B antibody (n = 8) with a specificity of 53.6% and a sensitivity of 36.6%. The present dermoscopic finding that the completely flattened pattern (IV) is predominant in definite Sjs patients may indicate a useful marker for suspicion of Sjs.
16766091 [Pseudo-Sjogren's syndrome and bulimia]. 2006 Sep INTRODUCTION: Bilateral parotid enlargement are presenting features of some metabolic and systemic disease but also of chronic emesis. CASE RECORD: A 24-year old woman consulted during three years many physicians asking for the treatment of a painless parotid swelling confusing with a Sjogren's syndrome. After an initial denial, the weight history, alteration of tooth wear and hypokaliemia conducted to admit a self inducing vomiting with bulimia nervosa. CONCLUSION: Gender, young age, weight history, tooth alteration and electrolytic disorders are the main diagnostic tool of this dissimulated etiology of parotid swelling.
16871352 Pulmonary hypertension in a patient with adult-onset Stills disease. 2007 Aug Pulmonary manifestations of adult-onset Still's disease (AOSD) include aseptic pneumonitis, pleural effusions, rarely acute respiratory distress syndrome, and restrictive lung disease. Pulmonary arterial hypertension (PAH) occurs with several rheumatologic diseases, however, has only been reported once in AOSD. We describe a 29-year-old woman with a 9-year history of AOSD, who developed PAH without any other obvious cause. Therefore, we conclude that this is likely a result of pulmonary vascular changes related to AOSD.
17706449 Efficacy of thalidomide in systemic onset juvenile rheumatoid arthritis. 2007 Oct Thalidomide is an immunomodulating agent which reverses many of the cytokine disturbances seen in systemic onset juvenile idiopathic arthritis (SoJIA) with inadequate response to other treatments. We report 3 cases of recalcitrant SoJIA which improved dramatically after treatment with thalidomide. PATIENTS: Three children aged 9, 8, and 6 years diagnosed with SoJIA treated with conventional therapy including NSAIDs, corticosteroids, methotrexate and etanercept failed to respond fully and their condition worsened. Thalidomide was begun based on two previous reports showing its efficacy in recalcitrant SoJIA. RESULTS: Thalidomide produced successful remission of the disease in all 3 patients according to the preliminary criteria for inactive disease and clinical remission of JIA. CONCLUSION: Thalidomide may be a viable, alternative corticoid-sparing therapy in patients with recalcitrant, multidrug-resistant SoJIA.
19260326 [Beneficial effect of total flavonoids of Chrysanthemum indicum on adjuvant arthritis by i 2008 Dec OBJECTIVE: To investigate the effect on the extract of total flavonoids of Chrysanthemum indicum (TFC) on adjuvant arthritis synovial cells. METHOD: SD rats were divided randomly into six groups including normal, model, TFC (84, 168, 336 mg x kg(-1)) and control drug Tripterygium glycosides (30 mg x kg(-1)) groups. Adjuvant arthritis rat model was induced by a single intradermal injection of 0.1 mL of the complete Freund's adjuvant into the right hind feet pads of the SD rats. The proliferation of synoviocyte was measured by MT; The apoptosis rates of synovial cells were evaluated using TUNEL and FCM analysis. RESULT: TFC resulted in a dose-dependent way in inhibiting the proliferation of synovial and inducing the apoptosis of synovium and synoviocytes in vivo. CONCLUSION: TFC can inhibit proliferation and induce apoptosis in synovial cells, and exert therapeutical effect on rheumatoid arthritis.
17929125 Proposal for juvenile idiopathic arthritis guidance on diagnosis and treatment for primary 2007 The Pediatric Standing Committee of the Japan College of Rheumatology, in collaboration with the Pediatric Rheumatology Association of Japan, produced guidance on the diagnosis and treatment for juvenile idiopathic arthritis (JIA) for primary care pediatricians and nonpediatric rheumatologists in Japan. This guidance aims to achieve early diagnosis and treatment for JIA, which is similar to adult rheumatoid arthritis (RA), based on recent progress in rheumatology, and to resolve arthritis at an early stage and improve the prognosis of the affected inflammatory joints. It describes clinical symptoms and laboratory findings characteristic to JIA in order to make early diagnosis and treatment possible, and also serves as a triage of patients who are refractory to the treatment protocol described here and need more aggressive interventions. However, because JIA is a complicated and heterogeneous disease and the optimal treatment approach can be diverse and different patient by patient, these guidelines should be viewed as recommendations and be individualized according to the condition of the patient. Finally, we hope that this guidance will trigger exploration for further information by referring to the textbooks and literature listed at the end of these guidelines.
17762613 Measuring clinical response and remission in juvenile idiopathic arthritis. 2007 Sep PURPOSE OF REVIEW: The increasing availability of new medications for the treatment of juvenile idiopathic arthritis has made the accurate assessment of treatment outcomes critically important. The purpose of this review is to describe recent investigations focused on the development of new outcome measures in the domains of disease activity and joint damage, and to summarize recently published data within the area of health-related quality of life. RECENT FINDINGS: Since the development of the preliminary definition of disease improvement in 1997, the American College of Rheumatology pediatric response criteria have become the primary outcome measures in therapeutic trials in juvenile idiopathic arthritis. Additional definitions, including preliminary definitions of flare and remission have subsequently been added. Investigations have also sought to determine whether measures currently in use in adult rheumatoid arthritis might have utility in juvenile idiopathic arthritis. As the pathogenesis of juvenile idiopathic arthritis becomes better understood, biomarkers have significant potential as outcome measures. Lastly, recent reports regarding the health-related quality of life in large cohorts of children with juvenile idiopathic arthritis are important in guiding investigators towards areas most in need of improved treatment. SUMMARY: Significant progress has been made in the measurement of outcomes in juvenile idiopathic arthritis. Outcome measures will continue to be designed and tested to keep pace with the development of new therapies and the improved understanding of the disease pathogenesis.
