Objective: To develop evidence-based recommendations for the management of fibromyalgia syndrome. Methods: A multidisciplinary task force was formed representing 11 European countries. The design of the study, including search strategy, participants, interventions, outcome measures, data collection and analytical method, was defined at the outset. A systematic review was undertaken with the keywords ''fibromyalgia'', ''treatment or management'' and ''trial''. Studies were excluded if they did not utilise the American College of Rheumatology classification criteria, were not clinical trials, or included patients with chronic fatigue syndrome or myalgic encephalomyelitis. Primary outcome measures were change in pain assessed by visual analogue scale and fibromyalgia impact questionnaire. The quality of the studies was categorised based on randomisation, blinding and allocation concealment. Only the highest quality studies were used to base recommendations on. When there was insufficient evidence from the literature, a Delphi process was used to provide basis for recommendation. Results: 146 studies were eligible for the review. 39 pharmacological intervention studies and 59 non-pharmacological were included in the final recommendation summary tables once those of a lower quality or with insufficient data were separated. The categories of treatment identified were antidepressants, analgesics, and ''other pharmacological'' and exercise, cognitive behavioural therapy, education, dietary interventions and ''other non-pharmacological''. In many studies sample size was small and the quality of the study was insufficient for strong recommendations to be made. Conclusions: Nine recommendations for the management of fibromyalgia syndrome were developed using a systematic review and expert consensus.Fibromyalgia syndrome (FMS) is a common rheumatological condition characterised by chronic widespread pain and reduced pain threshold, with hyperalgesia and allodynia. Associated features include fatigue, depression, anxiety, sleep disturbance, headache, migraine, variable bowel habits, diffuse abdominal pain and urinary frequency. Although effective treatments are available 12-14 no guidelines exist for the management of FMS. The objectives were to ascertain the strength of the research evidence on the effectiveness of treatment of FMS and develop recommendations for its management based on the best available evidence and expert opinion to inform healthcare professionals. METHODS ParticipantsA multidisciplinary taskforce was formed consisting of 19 experts in FMS representing 11 European countries. Search strategyA systematic search of Medline, PubMed, EmBASE, PsycINFO, CINAHL, Web of Sciences, Science Citation Indices, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews using the keywords: ''fibromyalgia'', ''treatment or management'' and ''trial'' for all publications till the end of December 2005 was carried out. A manual search of the bibliographies of trials was undertaken to...

SummaryIn serum incubated at 36° C for 18-24 hours a factor (DAS) develops which on intravenous injection into cats evokes platelet aggregation followed by an increase in pulmonary vascular resistance (PVR). This change in PVR is mediated via the platelets since it significantly correlates with the preinjection platelet count. There is evidence that phosphatidic acids (PA) and lysophosphatidic acids (LPA) are the active components of DAS. Investigations performed on platelet-rich plasma from man, cat, pig, dog, rabbit, guinea pig, and rat demonstrate that only human and feline platelets exposed to PA or to LPA are aggregated. Feline platelets are more sensitive to either compound than are the platelets from men; however, human platelets exhibit two exceptional properties, a) the sensitivity rapidly declines with time, b) pretreatment with subthreshold concentrations of LPA or PA induces a specific tachyphylaxis.

MIP-1alpha levels were elevated in patients with BD, and correlated well with IL-8, RANTES, and MCP-1 levels. These results suggest that the increased MIP-1alpha levels in serum of BD patients may lead to activation and migration of leukocytes, playing a role, like other chemokines, in the pathogenesis of BD.
