Brucellosis is a zoonosis that is transmissible to humans. It is a disease with multi-systemic involvement caused by the genus Brucella. Neurological complications, including meningitis, meningo-encephalitis, myelitis-radiculoneuritis, brain abscess, epidural abscess and meningo-vascular syndromes, are rarely encountered. We present a patient presenting with acute onset myositis. This kind of presentation has not previously been reported in the English language literature. We conclude that the diagnosis of neuro-brucellosis should be considered in patients presenting with muscle weakness.

Brucellosis, a multisystem infectious disorder, continues to be a serious public health problem in some parts of the world. Neurobrucellosis constitutes about 4% of all brucellosis cases. Brucellosis-associated myositis is extremely rare, and there is only 1 reported case in the English literature. We report a 16-year-old boy with subacute, fluctuating, progressive muscle pain, with tenderness, swelling, and diffuse, asymmetric weakness. He also had significantly elevated serum Brucella titers and a muscle biopsy showed inflammatory granulomatous myositis. We review the literature on myositis associated with brucellosis.

Diffuse myositis with progression to rhabdomyolysis has been reported in association with wide range of viral infections. We report a case of polymyositis-like syndrome complicated by rhabdomyolysis secondary to brucellosis. This case report thus contributes yet another atypical presentation to a disease already infamous for its protean manifestations.

Brucellosis infection is a multisystem disease, with a broad spectrum of symptoms. We investigated the existence of clusters of infected patients according to their clinical presentation. Using national surveillance data from the Electronic-Integrated Disease Surveillance System, we applied a latent class cluster (LCC) analysis on symptoms to determine clusters of brucellosis cases. A total of 454 cases reported between July 2011 and July 2013 were analyzed. LCC identified a two-cluster model and the Vuong-Lo-Mendell-Rubin likelihood ratio supported the cluster model. Brucellosis cases in the second cluster (19%) reported higher percentages of poly-lymphadenopathy, hepatomegaly, arthritis, myositis, and neuritis and changes in liver function tests compared to cases of the first cluster. Patients in the second cluster had a severe brucellosis disease course and were associated with longer delay in seeking medical attention. Moreover, most of them were from Beylagan, a region focused on sheep and goat livestock production in south-central Azerbaijan. Patients in cluster 2 accounted for one-quarter of brucellosis cases and had a more severe clinical presentation. Delay in seeking medical care may explain severe illness. Future work needs to determine the factors that influence brucellosis case seeking and identify brucellosis species, particularly among cases from Beylagan.

Rifampicin has been widely used due to its broad antibacterial spectrum. Acute haemolysis is a rarely encountered complication of rifampicin. A 58-year-old woman was admitted to our department because of high-grade fever with rigors, accompanied by abdominal and lumbar pain and laboratory evidence of acute haemolysis. She had been treated for brucellosis initially with doxycycline and streptomycin. Due to subsequent appearance of myositis, ciprofloxacin and rifampicin were added for treatment of localised brucellosis. After intravenous administration of rifampicin, the patient deteriorated significantly. After exclusion of other causes of haemolysis, autoimmune haemolytic anaemia related to rifampicin was established by strongly positive direct Coombs test. Drug withdrawal in conjunction with intravenous immune globulin and prednisolone resulted in resolution of haemolysis and no relapse in the ensuing 1-year period. Our case highlights the importance of recognising commonly administrative drugs as cause of haemolytic anaemia, that can often be life threatening.
