Resumo: Human herpesvirus 6 (HHV-6) has been reported to be associated with multiple sclerosis (MS) and Guillain-Barré syndrome (GBS). We analyzed cell-free HHV-6 DNA as an indication of active infection in the peripheral blood and cerebrospinal fluid (CSF) of Swedish patients with GBS, patients with chronic inflammatory demyelinating polyradiculoneuropathy, treatment-naïve patients with possible MS, interferon-? treated MS patients [with or without neutralizing antibodies (NAbs)], and control patients with headache. One of 14 GBS patients and one of eight patients with chronic inflammatory demyelinating polyradiculoneuropathy were positive for HHV-6 DNA in serum. Of the 27 treatment-naïve possible MS patients, two were positive in plasma and one in CSF. HHV-6 DNA was detected in the serum of three of 79 NAb+ patients and one of 102 NAb-interferon-? treated MS patients. HHV-6 DNA could not be detected in the plasma or CSF of any of the 33 controls, although the differences were not statistically significant. Our results do not suggest active HHV-6 infection to be a common phenomenon in any of the patient groups studied.
