In this prospective study of 73 relapsing remitting multiple sclerosis patients followed up for a mean of 1.7 years, the relation was tested between serologically defined Chlamydia pneumoniae (CP) infection periods and exacerbation rate.

Episodes of serologically defined CP infections were observed in a subgroup, and these episodes were associated with increased risk for exacerbation.

CP polymerase chain reaction was positive in most of the CP seropositive patients.

No correlation was found between the anti-CP antibody increase and titers of control antibodies.
