Severe, persisting, steroid-responsive Dengue myositis.

Abstract

OBJECTIVES:

Short-term, general muscle affection is frequent in Dengue infection, but severe, persisting, myositis has not been reported.

STUDY DESIGN:

Case report.

RESULTS:

The patient is a 38 years old, HIV-negative male who developed sudden-onset fever up to 40.0 degrees C, headache, and sore eyes upon looking into light when on holidays in Thailand. One day after onset severe myalgias occurred in the shoulder girdle and hip girdle muscles. Clinical examination was normal, but blood work revealed elevated creatine-phosphokinase, glutamate-oxalate transaminase, and glutamate pyruvate transaminase, leucopenia and thrombocytopenia. Antibodies against Dengue viruses type 2 and 4 were positive and classical Dengue fever was diagnosed. The infection resolved upon symptomatic therapy, but myalgias, responsive only to opiates, resolved persistently not before the administration of corticosteroids, 2 months after onset.

CONCLUSIONS:

The case shows that Dengue fever may also cause persisting, severe, myositis for weeks, which do not respond to non-steroidal analgesics, but promptly to corticosteroids.
