Intervertebral discitis caused by nontypeable Haemophilus influenzae in an adult: Case report

INTRODUCTION: Haemophilus influenzae is a common cause of bacterial meningitis in children and can cause upper respiratory tract infections in adults, but has yet to be reported solely involving intervertebral discitis. PRESENTATION OF CASE: A 67-year-old builder presenting with fever, myalgia and back pain is found to have intervertebral discitis (confirmed on MRI) caused by H. influenzae (identified on blood cultures). DISCUSSION: A nontypeable form of H. influenzae has not been reported causing discitis. We describe a case in a relatively fit individual who was treated successfully with antimicrobial treatment. A preceding upper respiratory tract infection is the presumed source of infection, predisposed by long-term low-dose steroid therapy. CONCLUSION: H. influenzae is a rare, but treatable cause of discitis. (C) 2012 Surgical Associates Ltd. Published by Elsevier Ltd.
