炎性肌病通常包括多发性肌炎、皮肌炎、包涵体肌炎和化脓性肌炎。前三者的发病机制与病毒感染相关。实验证明,病毒可以造成动物肌肉的急性炎症,其中甲病毒、流感病毒和柯萨奇病毒对肌肉有特别的亲嗜力。上述病毒感染人类常伴有严重的肌痛,因此推测这种肌痛可能与病毒感染有关。 Inflammatory myopathies usually include polymyositis, dermatomyositis, inclusion body myositis, and suppurative myositis. The pathogenesis of the first three are related to viral infection. Experiments show that the virus can cause acute inflammation of animal muscles, of which alphavirus, influenza virus and Coxsackie virus have a special affinity for muscle. The virus infection in humans is often accompanied by severe muscle pain, speculated that this muscle pain may be related to viral infection.
