Researchers suppose that the first choice for treating both neutropenia and arthritis is methotrexate, which is safe, effective and well tolerated in these patients.[2] Many studies suggest that application of rituximab is useful find more in the treatment of FS, while other researchers have found a different result.[3] Controlled trials of different

treatment modalities are not available because of the rarity of this syndrome. Splenectomy has produced a long-term hematologic response in 80% of patients but is usually reserved at the end of the treatment algorithm for treatment-resistant cases.[4] In some patients with FS, the presence of antibodies against neutrophils has Hydroxychloroquine been described, which might be associated with increased neutrophil destruction. The underlying mechanism of developing neutropenia in FS is similar to that in other forms of immune-mediated neutropenia.[5] However, there are no reports of the prevalence of association between hyperthyroidism and FS. Thus, autoimmune or immunologic processes were assumed in the pathogenesis of both autoimmune thyroid diseases (Graves’ disease) and FS. It had become recognized that Th1/Th2 balance controls the immune system. From the viewpoint of imbalance,

autoimmune Graves’ disease was considered to be a Th2-type disease.[6] Systemic involvement in RA is characterized by B cell overactivity, immune complex formation and complement consumption, suggesting that Th2 cells are involved in the pathogenesis of extra-articular manifestation of FS. Therefore, regarding Th1/Th2 imbalance, it is not surprising that there is a prevalence of Graves’ disease

in FS patients. Leflunomide may exert its effects by inhibiting the mitochondrial enzyme dihydroorotate dehydrogenase, which plays a pivotal role in the synthesis of the pyrimidine ribonucleotide uridine monophosphate (rUMP). Therefore, we propose that leflunomide prevents the expansion of activated and autoimmune lymphocytes by interfering with the cell cycle progression caused by inadequate production of rUMP.[7] This study was supported by ‘The selleck compound Incubative Program for Youth Scientists of Jiangxi Province, China’ no. 20112BCB23029. There is no potential conflict of interest in this paper. “
“Aim:  To determine the prevalence, correlates and impact of shoulder pain in a population-based sample. Methods:  The North West Adelaide Health Study is a representative longitudinal cohort study of people aged 18 years and over. The original sample was randomly selected and recruited by telephone interview. Overall, 3206 participants returned to the clinic during the second stage (2004–2006) and were asked to report whether they had pain, aching or stiffness on most days in either of their shoulders.
