The Central Nervous System

Neurosyphilis refers to infection of the central nervous system byTreponema pallidum, which may occur at any stage. Neurosyphilis has been categorized in many ways including early and late, asymptomatic versus symptomatic and infectious versus non-infectious. Late neurosyphilis primarily affects the central nervous system parenchyma, and occurs beyond early latent syphilis, years to decades after the initial infection. Associated clinical syndromes include general paresis, tabes dorsalis, vision loss, hearing loss and psychiatric manifestations. Unique algorithms are recommended for HIV-infected and HIV-uninfected patients, as immunocompromised patients may present with serologic and cerebrospinal fluid findings that are different from immunocompetent hosts. Antibody assays include a VDRL assay and the FTA-Abs, while polymerase chain reaction forT. pallidumcan be used as direct detection assays for some specimens. This chapter reviews guidelines for specimen types and sample collection, and identifies two possible algorithms for use with immunocompromised and immunocompetent hosts using currently available tests in Canada, along with a review of treatment response and laboratory testing follow-up.

The Central Nervous System

Tick-borne encephalitis (TBE) is a viral infectious disease of the central nervous system caused by the tick-borne encephalitis virus (TBEV). TBE is usually a biphasic disease and in humans the virus can only be detected during the first (unspecific) phase of the disease. Pathogenesis of TBE is not well understood, but both direct viral effects and immune-mediated tissue damage of the central nervous system may contribute to the natural course of TBE. The effect of TBEV on the innate immune system has mainly been studied in vitro and in mouse models. Characterization of human immune responses to TBEV is primarily conducted in peripheral blood and cerebrospinal fluid, due to the inaccessibility of brain tissue for sample collection. Natural killer (NK) cells and T cells are activated during the second (meningo-encephalitic) phase of TBE. The potential involvement of other cell types has not been examined to date. Immune cells from peripheral blood, in particular neutrophils, T cells, B cells and NK cells, infiltrate into the cerebrospinal fluid of TBE patients.

At a quarterly meeting of this Association held last year at Nottingham, we showed the results of our experiments with toxins upon the spinal cord and brain of rabbits. Our main conclusion was, that the central nervous system could be infected by toxins passing up along the lymph channels of the perineural sheath. The method we employed in our experiments consisted in placing a celloidin capsule filled with a broth culture of an organism under the sciatic nerve or under the skin of the cheek; and we invariably found a resulting degeneration in the spinal cord or brain, according to the situation of the capsule. These lesions we found to be identical in morphological type and anatomical distribution with those found in the cord of early tabes dorsalis and in the brain and cord of general paralysis of the insane. The conclusion suggested by our work was that these two diseases, if toxic, were most probably infections of lymphogenous origin.

The Central Nervous System

Canine distemper is a systemic infection, frequently lethal in dogs. The canine distemper virus(CDV) causes a persistent infection within the central nervous system resulting in aprogressive, multifocal demyelinating disease. In dogs, CDV infection may lead togastrointestinal and/or respiratory signs, frequently with central nervous system involvement.Myoclonus has been a common and characteristic sign observed in dogs with distemperencephalomyelitis. However, the nervous form of distemper may occur in the absence ofmyoclonus and systemic involvement. This review will point the clinical course and theneurological signs of nervous distemper, as well the clinical syndromes of CDV infection,neuropathology of acute and chronic demyelination, and diagnostic aids of CDVencephalomyelitis.

According to V. I. Znamensky indicated for treatment in Matsesta: 1) diseases of the peripheral nervous system, -neuralgia, neuritis; 2) diseases of the central nervous system connected with disorders of the cardiovascular system, - hemiplegia and hemiparesis due to thrombosis and embolism; (treatment of acute forms of the mentioned diseases, it goes without saying, is contraindicated); 3) Luetic diseases,-vascular syphilis of the brain, lues cerebrospinalis, meningo-myelitis, tabes dorsalis incipiens and Luetic radiculitis (here; baths, giving increase of metabolism and excretions, make possible mercury treatment with impunity); 4) remnants of lethargic encephalitis.

The Central Nervous System

Although modern research has placed the treatment of syphilis on a scientific basis, the Treponema pallidum continues to exact a heavy toll among all classes of society. The seriousness of the disease is largely due to the ever-present risk of a return of symptoms, perhaps many years after the acquirement of infection, and to the frequency with which the central nervous system is attacked.

This paper briefly reviews the factors which influence the concentrations of proteins, particularly immunoglobulins, within the CSF and how antibodies which are locally synthesized within the central nervous system can be detected by the laboratory. The use of nitrocellulose immunoblotting for the identification of antibodies which are specific to Treponema pallidum and Human Immunodeficiency Virus Type-1 are discussed.

And Storage

Treponema pallidum DNA from even small numbers of organisms was detectable in cerebrospinal fluid (CSF) stored at room temperature or at 4°C for several hours and in CSF subjected to three freeze-thaw cycles. These results suggest that negative PCR results forT. pallidum from patients diagnosed with T. pallidum invasion of the central nervous system are probably not due to the loss of target DNA prior to testing.
