Abstract

Objectives: We explored causes of in-hospital mortality in patients with inflammatory myositis at a tertiary care center in Northern India.

Methods: Records of adults and children diagnosed with dermatomyositis (DM), polymyositis, or anti-synthetase syndrome (ASSD) who died between 2000 and 2018 were reviewed, and causes of death were determined.

Results: Of the 38 patients, 20 had DM (including 2 clinically amyopathic DM), 4 juvenile DM, 12 polymyositis, whereas 2 had ASSD. Median age at death was 42.0 (interquartile range, 32.8-52.5) years. Median disease duration at death was 18.5 (interquartile range, 2.0-23.5) months. Twenty-four (63.2%) had infection as the primary cause of death. Other causes of death included pharyngeal muscle weakness and aspiration (n = 6), myocarditis (n = 2), respiratory failure (n = 2), cerebral bleed (n = 2), and pulmonary embolism (n = 1). One patient succumbed to rapidly progressive interstitial lung disease, whereas another patient with ASSD died following respiratory distress after rituximab infusion. In post hoc analysis, although thrombocytopenia appeared to be a risk factor for early mortality (odds ratio, 13.3; 95% confidence interval, 1.4-123.8; p = 0.01), this was not supported in the multivariate analysis.

Conclusions: Infections are the most common cause of in-hospital mortality in myositis patients.
