ABSTRACT It has been suggested that Chlamydia pneumoniae (C. pneumoniae) is involved in the pathogenesis of diverse diseases of the central nervous system (CNS), including multiple sclerosis. We report the case of a 12-year-old male with isolated recurrent optic neuritis and an associated CNS infection with C. pneumoniae. The patient presented with three attacks of optic neuritis within 5 months. A positive polymerase chain reaction for C. pneumoniae in the cerebrospinal fluid led to the diagnosis of a CNS infection with C. pneumoniae. After treatment with the antibiotic rifampicin, he experienced no further attacks during the follow-up period of 6 years. These findings suggest the possibility of a C. pneumoniae infection as a contributing factor or even causative event for the development of optic neuritis.

    ABSTRACT: Lyme optic neuritis (ON) is a rare disease and only a few cases have been reported. We describe two cases of isolated Lyme ON, one with recurrence 9 months after the appearance of initial symptoms. Diagnosis criteria for multiple sclerosis and neuromyelitis optica were not met. The etiological diagnosis was based on European case definition criteria for neuroborreliosis. Both patients had positive serum and cerebrospinal fluid serology, a positive intrathecal anti-Borrelia antibody index, and a good outcome on ceftriaxone. Specific diagnosis of Lyme ON is important since improvement of visual acuity is possible with specific antibiotherapy, even after many months.

    ABSTRACT: To determine if Chlamydia pneumoniae infection is associated with primary open-angle glaucoma (POAG). Consecutive patients with newly diagnosed primary POAG attending the Glaucoma clinic of Keio University Hospital between June 2007 and January 2008 were considered for inclusion in this prospective case-control study. Forty consecutive POAG patients and 41 normal healthy individuals as a control population met the inclusion criteria. The exclusion criteria for both groups were; taking steroids or immunosuppressive agents, smoking, and history of any acute or chronic systemic disease including stroke, heart attack, diabetes mellitus, hypertension, asthma, and autoimmune diseases. The serum was analyzed for C. pneumoniae and C. trachomatis immunoglobulin G antibody titers by enzyme-linked immunosorbent assay. Seroactivity to each antigen between case and control groups was evaluated by Mann-Whitney U test. The age, male/female ratio, and intraocular pressure of the cases and control groups were not significantly different. Immunoglobulin G titers for C. pneuemoniae was significantly higher in patients with POAG than in controls (P=0.009). The titers to C. trachomatis were not significantly different between the 2 groups (P=0.99). The results suggest that higher C. pneumoniae titers are associated with POAG. If confirmed, this may indicate either a common factor that causes susceptibilities to both glaucoma and C. pneumoniae infection or that C. pneumoniae may be a causal factor for developing POAG.

    ABSTRACT: Close similarities in the courses of multiple sclerosis and schizophrenia laid the theoretical ground for attempting to find a common infectious aetiology for the two diseases. Chlamydia pneumoniae, which belongs to the rickettsial family of microorganisms has been linked to both diseases. It is postulated that since rickettsial microorganisms are ubiquitous in human populations they and the human species normally live in peaceful coexistence. In rare cases, for unknown reasons, varieties of them may become aggressive and pathogenic. The kynurenic acid hypothesis of schizophrenia has attracted much attention. It also seems to have initiated a paradigmatic shift from the hitherto prevailing serological research approach to one which focuses on immunological factors. An open clinical pilot study in which, during 2006, eight female and five male patients with psychotic symptoms were treated with a combination of antibiotics is presented, to which, in the beginning of 2007 two female patients suffering from severe and long standing chronic fatigue syndrome were added. On one year follow-up, six out of the eight female patients showed stable excellent treatment results, whereas two were rated as showing significant treatment results. Four of the five men who entered the study were suffering from chronic schizophrenia, whereas the fifth, was a case of severe acute catatonic schizophrenia. Two of the male patients showed significant treatment results, whereas three of them were rated as having had a slight to moderate improvement. No less than three of the women had suffered their first episode of psychosis after giving birth to their first (and only) child. This finding, as these women all responded excellently to treatment with antibiotics, indicates that post partum psychosis could be regarded as an infectious complication of childbirth of, as to the causative agent, unknown aetiology. High priority ought therefore be given to initiate controlled clinical trials with antibiotic treatment of this serious condition. The otherwise promising results of the pilot study seem to warrant further and controlled clinical trials with treatment with antibiotics of patients with psychotic symptoms. As the second patient with psychotic symptoms to enter the study, had a long standing history of chronic fatigue, where an initial treatment with the antidepressant fluoxetine had only worsened her condition, whereas ninety days of treatment with antibiotics, combined with vitamin B injections, effected a complete recovery, the author decided, when two patients with long standing and incapacitating chronic fatigue syndromes sought the clinic in February and March 2007, to include them in the study. The first of them, after sixty days of treatment with antibiotics showed excellent treatment results on follow-up one year later, whereas the second, who also took the combination of antibiotics for sixty days, was rated as having shown a significant improvement.
