Fever and severe myalgia in a tropical country like India bring to mind leptospirosis, rickettsioses, dengue, and other viral fevers. Enteric fever is widely prevalent in Asia, but myositis has not been previously described in Salmonella paratyphi A bacteremia.
MATERIALS AND METHODS
Retrospectively, we recruited patients with enteric fever admitted to our treating unit over a 6-month period. Demography, historical, clinical, and laboratory data were obtained. Data of culture-positive S. paratyphi A patients were analyzed and were compared with those patients with culture-negative enteric fever.
Forty-three cases were found in total with 19 of S. paratyphi A bacteremia. Elevations in creatine kinase (CK) ranged from one-and-half to six times normal. Forty-seven percent had thrombocytopenia and alanine transaminase elevations, while aspartate transaminase elevations were seen in 17 patients, which corresponded to those with elevated CK levels.
Myositis associated with S. typhi and S. paratyphi is very rare and is more often due to non-typhoidal Salmonellae. Elevated creatine kinase was seen in most of our patients with S. paratyphi A bacteremia. Such myositis has not been described previously and hence, myalgia with fever in a tropical country could be a harbinger of paratyphoid fever.
