In the three decades since Bohan and Peter published their criteria which have long stood as the gold standard for diagnosis in clinical practice as well as inclusion into clinical trials, more sophisticated understanding of immunopathogenesis,
histology, and specific autoantibody associations has broadened our understanding of these diseases. This editorial review examines the diverse approaches between different subspecialists in deriving appropriate IIM classification utilizing this updated knowledge.
Recent findings
Several investigators PI3K inhibitor have proposed improved IIM classification criteria. More recently, larger scale consensus efforts have been undertaken by various expert groups including the European Neuromuscular Centre (ENMC) and The International Myositis Assessment and Clinical Studies Group (IMACS). The intent is to refine the classification criteria utilizing our enhanced understanding which has matured since the original publication of Bohan and Peter’s proposal in 1975.
Summary
Many diagnostic/classification criteria have been proposed for different forms of IIM over the last three decades.
The majority of these have been based on clinical impressions rather than rigorous data analyses or expert consensus and none has been fully tested for sensitivity buy AG-881 or specificity using appropriately powered studies that take into account relevant disease confounders. Different sets of criteria proposed and adopted by different specialties hamper the ability to compare clinical studies and assess clinical trials’ outcomes. Large, multicentered, multispecialty
studies are required to develop improved IIM criteria.”
“Malaria is one of the most common and serious infectious diseases in the tropics and subtropics. For high-risk travelers to endemic regions, malaria chemoprophylaxis is recommended. Internationally, atovaquone-proguanil (A/P), Fosbretabulin mw mefloquine (MEF), or doxycycline (DOX) are the prescribed malaria chemoprophylactic drugs. However, A/P and DOX are not approved in Japan. Therefore, the data on A/P for malaria chemoprophylaxis in Japanese travelers are not clear. We analyzed questionnaire survey data obtained in Hibiya Clinic to assess the safety and tolerability of A/P and compare them with those of MEF for non-immune Japanese travelers. A/P was given to 278 travelers and MEF to 38 travelers. The mean duration of each prophylaxis is for 20.0 +/- A 9.6 and 59.0 +/- A 15.9 days, respectively. Nine travelers discontinued prophylaxis: 5 in the A/P prescribed group (A/P group) and 4 in the MEF prescribed group (MEF group), and the rate of discontinuation was significantly less in the A/P group. The frequency of adverse events was significantly less in the A/P group than in the MEF group [52 cases (18.8 %) vs. 14 cases (36.8 %), respectively]. In particular, the frequency of psychoneurotic adverse events was significantly less in the A/P group.
