Autophagic myopathies / myofibrillar myopathies / distal myopathies / pompe disease

Chloroquine (CQ) and hydroxychloroquine (HCQ) are used in the treatment of malaria and various connective tissue diseases (CTD). They have been associated with muscle toxicity, mostly described as a proximal myopathy with evidence of lysosomal dysfunction on muscle biopsy. As patients with CTD may have muscle weakness due to myositis or steroid myopathy, the diagnosis can be missed or delayed. In this retrospective study, we aimed to define the clinical phenotype, laboratory features and treatment outcomes of CQ/HCQ-myopathy.
