Lyme meningoencephalitis: report of a severe, penicillin-re sistant case. Diringer MN, Halperin JJ, Dattwyler RJ.
Although Lyme disease frequently attacks the central nervous system, this involvement is rarely severe, and high-dose intravenous penicillin usually is adequate treatment. The patient we describe developed severe Lyme meningoencephalitis despite receiving a full course of penicillin, and his condition continued to deteriorate after reinstitution of this treatment. Intravenous chloramphenicol was used successfully and resulted in a substantial improvement.
