Amyloidosis is a heterogeneous group of disorders characterized by misfolding of extracellular proteins. The two most common forms are light‐chain (AL) and reactive (AA) amyloidosis. Pulmonary amyloidosis secondary to Sjogren's syndrome (SS) is rare, and there is a paucity of data on its clinical and radiological features. We describe the case of a 41‐year‐old woman with diffuse septal pulmonary AL (λ) amyloidosis related to SS, in the absence of systemic amyloidosis. A systematic search for pulmonary amyloidosis in SS yielded 37 cases. Amyloidosis occured almost exclusively in women (96.5%). Cough and dyspnoea (56%) were the most common symptoms. The diagnosis of pulmonary amyloidosis was made subsequent to that of SS, with a median delay of 7 years. Radiologically, diffuse nodules with (45.5%) or without (33.3%) multiple cysts were the most common pattern. Most cases were related to nodular AL amyloidosis (both κ and λ). Diffuse septal AA amyloidosis has been reported in SS. The index patient is the first documented case of diffuse septal pulmonary AL amyloidosis in SS, without systemic amyloidosis. Surgical lung biopsy (78%) is usually required to establish the diagnosis and rule out lymphoma. There is no data to support any definitive therapeutic intervention for SS‐related pulmonary amyloidosis. Observation is sufficient for nodular amyloidosis. Further studies are necessary to assess the efficacy of current therapies in diffuse septal amyloidosis secondary to SS. 相似文献

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease that presents with sicca symptoms of the main mucosal surfaces. Patients with pSS have a broad spectrum of laboratory features, such as cytopenias and hypergammaglobulinemia. Although hematological abnormalities are usually seen in pSS patients, agranulocytosis and autoimmune hemolytic anemia (AIHA) are rare. Here we describe a 40‐year‐old woman with pSS who developed both agranulocytosis and mixed‐type AIHA. An increased risk of malignancies has also been reported in pSS patients with hematological changes. Although there is no evidence of malignancies, this patient should be closely followed up in case of developing lymphoma. 相似文献

Objective: Anti‐α‐fodrin autoantibody has been reported to be a highly specific and sensitive test for the diagnosis of Sjogren's syndrome (SS). The objective of our report is to investigate the sensitivity and specificity of anti‐α‐fodrin antibody in patients with SS and its correlation with clinical manifestations. Methods: Recombinant human α‐fodrin was used as envelope antigen in enzyme‐linked immunosorbent assay (ELISA) to detect the relatively specific autoantibody in sera of 42 primary SS, 24 secondary SS with systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA), and 40 other connective tissue diseases (CTDs) (SLE 17, RA 8, ankylosing spondylitis 5, dermatomyositis 5, systemic schlerosis 3, mixed connective tissue disease 1, Takayasu's disease 1) patients. Results: Antibodies against α‐fodrin were present in 59.5% of primary SS patients, 31.5% of secondary SS patients, 35.0% and 11.3% of other CTD patients and controls, respectively; the specificity of anti‐α‐fodrin antibody was 79.4% in patients with SS. It showed no significant difference between primary and secondary SS (P > 0.05), as well as SS compared with other CTD patients (P > 0.05). The positive rates of antibodies against α‐fodrin in CTD patients were significantly higher than those in non‐CTD patients and normal controls (P < 0.01). The presence of anti‐α‐fodrin antibodies has no significant correlation with clinical manifestations or other autoantibodies, while the levels of sera IgG and erythrocyte sedimentation rate (ESR) are higher in α‐fodrin antibody‐positive patients (IgG: 23.2 vs. 18.6, P < 0.05; ESR: 52.9 vs. 37.1, P < 0.05) than α‐fodrin antibody‐negative patients. Anti‐α‐fodrin antibodies are all negative in anti‐SS antigen A and antinuclear antibody‐negative SS patients. Conclusion: The result showed a lower sensitivity and specificity for anti‐α‐fodrin antibody as a diagnostic marker of SS, compared with previous reports. Anti‐α‐fodrin antibodies had no significant association with clinical manifestations, but might be related to the sera IgG level. Antibodies against α‐fodrin played no important roles in diagnosis of antibody‐negative SS patients. 相似文献

A 38-year-old woman with relapsing longitudinal extensive transverse myelitis and Sjogren's syndrome (SS) was admitted with lower extremity muscle weakness. Studies showed high serum titer of anti-aquaporin4 antibody and gadolinium-enhanced-MRI T1-weighted lesions within thoracic cord. Clinical findings suggested neuromyelitis optica-spectrum disorder (NMO-SD). High-dose corticosteroids, plasma exchange and cyclophosphamide were not effective. After starting tocilizumab, her neurological findings gradually improved. This report describes the first evidence to show tocilizumab could be effective for NMO-SD with SS. 相似文献

Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent, self‐limited attacks of fever usually accompanied by polyserositis. Sjögren's syndrome (SS) is a chronic autoimmune disease characterized by dry eyes, dry mouth and musculoskeletal system involvement. To our knowledge, coexistence of FMF and SS has not been reported before in the literature. We report a patient being followed up with the diagnosis of FMF over 20 years and later developing SS. 相似文献

This is a case report of Isaacs' syndrome in dermatomyositis. The patient presented with proximal muscle weakness, rash, elevated muscle enzyme, myopathic electromyograph and typical muscle biopsy. Ultimately he developed typical symptoms of Isaacs' syndrome which is an autoimmune channelopathy from voltage gated potassium channel antibody (anti‐VGKC) leading to dysfunction of axonal discharge at neuromuscular junctions. It shares some similar characteristics with dermatomyositis such as autoimmunity, its association with malignancy and the response to treatment. 相似文献

Inflammatory bowel disease has been reported to co-exist with other autoimmune diseases. Sjogren's syndrome is an autoimmune disorder characterized by xerostomy and/or xerophthalmy. Sjogren's syndrome occurring in IBD has been very rarely reported.A 45-year old woman diagnosed ten years ago with ulcerative pancolitis and primary sclerosing cholangitis was referred to our outpatient IBD clinic because of xerostomy but not for xerophthalmy for the previous three months. The patient had been under azathioprine maintenance treatment (2 mg/kg) and achieved long-term disease remission for the past 4 years. Patient clinical examination and laboratory tests were unremarkable. Salivary gland biopsy and complete ophthalmologic investigation were performed and the patient was diagnosed with Sjogren's syndrome.Understanding sicca manifestations in IBD is difficult since the pathogenesis of this intestinal disorder is not yet clear. Of these complex autoimmune phenomena which occur along with IBD it is quite difficult to categorize concomitant Sjogren's syndrome as primary or secondary and literature is conflicting. The possibility of Sjogren's syndrome should always be considered and properly investigated in patients diagnosed with inflammatory bowel disease who develop a constellation of constitutional sicca symptoms. 相似文献

Inflammatory bowel disease (IBD) is very common in developed countries, while it is relatively uncommon in Asian countries. However, the incidence of IBD has been increasing in some Asian countries in recent years. Most cases of ulcerative colitis (UC) in Asia are of the chronic relapsing type, run a milder course, and the fulminant type is rarely seen. There is no difference in clinical manifestations between Asian and developed countries. The incidence of Crohn's Disease (CD) is mainly in males in Asia, while it is mainly in females in developed countries. The clinical manifestations of CD are similar between both sets of countries. In China there are less fistulae and perianal diseases, and extraintestinal manifestations of CD are uncommon. In China, 5.6% of patients with UC have a family history, which is lower than 10-20% in developed countries. NOD2/CARD15 variants in the locus of 16q112 (IBD1) are significantly associated with the susceptibility of CD in developed countries, but NOD2/CARD15 variants have not been found in Asian CD patients. 相似文献
