Abstract
BACKGROUND AND OBJECTIVES The diagnosis of neurosyphilis (NS) lacks a true 'gold standard', making the diagnosis challenging while consequences of a misdiagnosis are potentially severe. The aim of this study was to evaluate the diagnostic performance of measuring an antibody index (AI) for the intrathecal synthesis of specific anti-Treponema pallidum (T. pallidum) IgG for the diagnosis of NS. METHODS Specific anti-T. pallidum IgG were measured simultaneously in paired cerebrospinal fluid (CSF)-serum samples collected retrospectively and prospectively between 2007 and 2022, from patients suspected of NS, in Switzerland. An AI was calculated to account for blood-brain barrier integrity. Area under the receiver operating characteristic curve, sensitivity/specificity and positive/negative predictive values of AI test were estimated. Two NS definitions were used: NS1 included patients with NS suspicion presenting with neurological symptoms and/or acute neurosensory signs, and positive T. Pallidum Hemagglutinations Assay (TPHA)/T. pallidum particle agglutination assay (TPPA) serology and CSF-TPHA/TPPA ≥320, and either CSF-leucocytes >5 cells/mm3 and/or CSF-protein >0.45 g/L and/or a reactive CSF-venereal disease research laboratory (VDRL)/rapid plasma reagin (RPR) test. NS2 included patients with suspected NS presenting with acute ocular and/or otologic symptoms, and positive TPHA/TPPA serology, and a favourable response to NS treatment. Controls were patients diagnosed with any other central nervous system (CNS) pathologies and with positive TPHA/TPPA serology. RESULTS The study included 71 NS (43 NS1 and 28 NS2) and 110 controls. With a threshold of ≥1.7, sensitivity and specificity of the specific AI test were 90.7% (CI 77.7 to 97.4) and 100% (CI 96.7 to 100.0), respectively, for NS1 and 14.3% (CI 4 to 32.7) and 100% (CI 96.7 to 100.0) for NS2. In patients suspected of NS with a CNS involvement (NS1 group), NS could be confirmed by the positivity of this specific AI. CONCLUSIONS Measurement of an intrathecal synthesis index of specific anti-T. pallidum IgG in patients with CSF inflammatory signs appears to be a valuable diagnostic test. However, in otic or ocular syphilis, presenting few CSF abnormalities, AI is not sufficient alone to confirm NS diagnosis.

Abstract
BACKGROUND In the 19th century, neurosyphilis was the most frequent cause of dementia in Western Europe. Now dementia caused by syphilis has become rare in Germany. We studied whether routine testing of patients with cognitive abnormalities or neuropathy for antibodies against Treponema pallidum has therapeutic consequences in geriatric patients. METHODS A Treponema pallidum electrochemiluminescence immunoassay (TP-ECLIA) is routinely performed in all in-patients treated at our institution with cognitve decline or neuropathy and no or insufficient previous diagnostic workup. Patients with a positive TP-ECLIA treated from October 2015 to January 2022 (76 months) were retrospectively evaluated. In cases of positive TP-ECLIA, further specific laboratory investigations were performed to assess whether antibiotic therapy was indicated. RESULTS In 42 of 4116 patients (1.0%), TP-ECLIA detected antibodies directed against Treponema in serum. Specifity of these antibodies was ensured by immunoblot in 22 patients (11 × positiv, 11 × borderline values). Treponema-specific IgM was detectable in the serum of one patient, in 3 patients the Rapid Plasma Reagin (RPR) test, a modified Venereal Disease Research Laboratory test (VDRL), in serum was positiv. CSF analysis was performed in 10 patients. One patient had CSF pleocytosis. In 2 other patients, the Treponema-specific IgG antibody index was elevated. 5 patients received antibiotic therapy (4 × ceftriaxone 2 g/d i.v., 1 × doxycycline 300 mg/d p.o.). CONCLUSION In approx. 1‰ of patients with previously undiagnosed or not sufficiently diagnosed cognitive decline or neuropathy, the diagnostic workup for active syphilis resulted in a course of antibiotic treatment.

Abstract
We herein report a 46-year-old man presenting with locked-in syndrome secondary to meningovascular syphilis. Brain magnetic resonance imaging (MRI) demonstrated multiple acute infarctions in the left ventromedial pons, right basis pontis, and left basal ganglia. His locked-in syndrome was hypothesized to have been caused by thrombosis of the small paramedian branches of the basilar artery due to syphilitic arteritis. This is a unique case of bilateral ventromedial pontine infarction caused by meningovascular syphilis that presented as locked-in syndrome. Meningovascular syphilis should be included in the differential diagnosis of uncommon stroke, particularly in young men.

Abstract
A review article is addressed the issue of the diagnosis and treatment of neurosyphilis that is developing against the background of HIV-infection. HIV-infected patients are at higher risk of neurologic, ocular and auricular manifestation of syphilis as well as treatment failures and relapses. Diagnosis of neurosyphilis in HIV-positive patients is complicated because both infections cause similar changes in the cerebrospinal fluid (CSF). The effectiveness of neurosyphilis treatment in patients with HIV co-infection is difficult to estimate, since the normalization of their CSF goes slower comparing to HIV-negatives. The increase in incidence of syphilis and HIV co-infection is anticipated in the coming years. This necessitates a comprehensive study of the problem and requires the development of new approaches to neurosyphilis diagnosis and treatment in co-infected patients.

Abstract
A 55-year-old man presented with a painless destruction of multiple joints and neurologic deficits. He was admitted with a painless pyogenic arthritis of the right ankle. Four years earlier, he had experienced instability of the right knee after an inexplicable, progressive but painless destruction of the joint. Radiographs showed erosive changes at the smaller joints of both hands and the left foot, as well as deformation and destruction of the right foot. Results from both treponemal and nontreponemal serologic test were positive in blood. The Treponema pallidum particle agglutination index was positive in the cerebrospinal fluid. Tabetic arthropathy was diagnosed.Tabetic arthropathy is a manifestation of neurosyphilis. Because syphilis is known as "the great imitator" and tertiary syphilis is rare, recognizing the disease is the biggest challenge for health care providers. Symptoms may mimic any other disease, and many different medical specialists may be faced with these patients, or as Sir William Osler put it: "He who knows syphilis, knows medicine." Initial diagnosis is usually made on serum and cerebrospinal fluid examination. Penicillin is an effective treatment for neurosyphilis to stop progression of neurologic damage, but it does not cure the previously developed tabetic arthropathy. This case is reported to raise awareness of this uncommon but important manifestation of tertiary syphilis. Unfamiliarity with the clinical presentation of tabetic arthropathy may lead to considerable delay in diagnosis.

Abstract
Background: Syphilis is caused by a spirochete Treponema pallidum. Invasion of the central nervous system (CNS) by T. pallidum may appear early during the course of disease. The diagnosis of confirmed neurosyphilis is based on the reactive Venereal Disease Research Laboratory (VDRL) in cerebrospinal fluid (CSF). Recent studies indicated that serum RPR ≥ 1:32 are associated with higher risk of reactivity of CSF VDRL. Aims: The main aim of the current study was to assess cerebrospinal fluid serological and biochemical abnormalities in HIV negative subjects with secondary and early latent syphilis and serum VDRL ≥ 1:32. Materials and Methods: Clinical and laboratory data of 33 HIV-negative patients with secondary and early latent syphilis, with the serum VDRL titer ≥ 1:32, who underwent a lumbar puncture and were treated in Department of Dermatology at Jagiellonian University School of Medicine in Cracow, were collected. Results: Clinical examination revealed no symptoms of CNS involvement in all patients. 18% (n = 6) of patients met the criteria of confirmed neurosyphilis (reactive CSF-VDRL). In 14 (42%) patients CSF WBC count ≥ 5/ul was found, and in 13 (39%) subjects there was elevated CSF protein concentration (≥ 45 mg/dL). 10 patients had CSF WBC count ≥ 5/ul and/or elevated CSF protein concentration (≥ 45 mg/dL) but CSF-VDRL was not reactive. Conclusions: Indications for CSF examination in HIV-negative patients with early syphilis are the subject of discussion. It seems that all patients with syphilis and with CSF abnormalities (reactive serological tests, elevated CSF WBC count, elevated protein concentration) should be treated according to protocols for neurosyphilis. But there is a need for identification of biomarkes in order to identify a group of patients with syphilis, in whom risk of such abnormalities is high.

Abstract
Borna disease virus (BDV) appears to cause meningoencephalitis and schizophreniform psychosis in sporadic cases according to earlier cerebrospinal fluid (CSF) inoculation experiments (Rott et al, 1991). However, CSF parameters in BDV seropositive psychiatric patients proved nearly all normal; only the most sensitive CSF/serum index I-BDV for intrathecally produced BDV specific IgG was pathologic in 10.5-29.0% (according to different methodological limits) of patients. An increase in sensitivity was attempted to detect specific IgG in CSF in a part of the cases by concentration. Concentration procedure does not significantly increase methodological bias according to a statistical analysis of the results. Our findings support the hypothesis that BDV may cause or contribute to the pathogenesis of a diagnostically broad pattern of psychiatric syndromes. The occurence of a spectrum of diagnoses is expected from non-specificity of psychiatric symptoms in other infectious diseases of the brain as well as from results in experimental Borna disease (BD) in animals, when a majority of the animals showed rather unspecific symptomatology due to slight, preferentially limbic encephalitis. Slight deficiencies from an earlier BDV infection could explain continuing symptoms in a part of the cases. Recurrences years after infection are well known in experimental and natural BD in animals. It remains open, whether this mechanism could play a more prominent role in a form of "symptomatic" cyclothymia and "symptomatic" schizophrenia, although the results of CSF investigations are more clear in BDV seropositive patients with major psychoses.

Abstract
Neurosyphilis is an infectious disease that has reappeared over the past two decades. It is caused by Treponema pallidum subspecies pallidum that can affect the central nervous system (CNS) during any stage of the disease. Besides early CNS involvement predominantly presenting with symptoms of meningitis, a parenchymal affection of the brain leading to severe neuropsychiatric symptoms particularly emerges at later stages, but is rarely seen nowadays due to early antibiotic treatment. Together with the clinical findings, a characteristic combination of serological and cerebrospinal fluid (CSF) abnormalities leads to the diagnosis of neurosyphilis and is required to assess its activity. However, particularly at later stages of disease and after antibiotic treatment, serological and CSF abnormalities may become ambiguous and, therefore, difficult to interpret. This can be accompanied by persisting or fluctuating neuropsychological deficits. To this day, no well-controlled clinical data exists concerning the treatment of late-stage neurosyphilis, neither on type, optimal dosage, duration, and long-term efficacy of antibiotic therapy. Therefore, treatment and follow-up of late-stage neurosyphilis are challenging tasks. Here, we present three cases of neurosyphilis with severe neuropsychiatric symptoms in non-immunocompromised patients and a review of the recent literature.

Abstract
Treponema pallidum subspecies pallidum, the causative agent of syphilis, disseminates to the central nervous system within days after exposure. Clinical manifestations can occur during any stage of the infection, and include asymptomatic neurosyphilis, acute meningeal syphilis, meningovascular syphilis, paretic neurosyphilis, and tabetic neurosyphilis. The majority of cases are reported in HIV-infected patients but the epidemiology of modern neurosyphilis is not well defined because of the paucity of population-based data. Decreasing reports of late neurosyphilis have been countered with increasing reports of early neurologic involvement. This review summarizes the clinical manifestations, diagnosis, and therapy of neurosyphilis, focusing on areas of continued controversy, and highlighting several important questions that remain unanswered. Since 2000, the rates of syphilis continue to increase. Given the effectiveness of penicillin therapy, these trends suggest a failure of prevention. Regrettably, rather than become an infection of historical significance, syphilis in the era of HIV continues to challenge researchers and clinicians.

Abstract
OBJECTIVES To review the management of a cohort of patients with positive treponemal serology and psychiatric and/or neurological disorders. METHODS A retrospective case note review of 172 patients with positive treponemal serology attending the Patrick Clement's Clinic, Central Middlesex Hospital between December 1990 and November 1995 was performed. RESULTS 101 men and 71 women were new attenders diagnosed with positive treponemal serology. A neurological problem was identified in 27 patients (12 women and 15 men) with psychiatric and/or neurological disorders, of whom 20 (six women and 14 men) underwent investigation of the cerebrospinal fluid (CSF). With the medical history and results of CSF-RPR and FTA tests, white cell count (WCC), and total protein level in the CSF, 10 patients (eight men and two women) were diagnosed with likely neurosyphilis and 17 with neurological disorders not thought to be caused by syphilis. The clinical features in those having neurosyphilis were sensorineural hearing loss (n = 5) and tabes dorsalis (n = 5). In the seven patients diagnosed with neurosyphilis who underwent CSF examination one patient had a reactive CSF-FTA, elevated protein, and elevated WCC; one patient had a reactive CSF-FTA and RPR with elevated protein; the total protein only was elevated in three cases and the WCC elevated in one case. Nine of the 10 patients with neurosyphilis received adequate neurosyphilitic treatment; one patient was lost to follow up. CONCLUSIONS The management of patients with positive treponemal serology and psychiatric and/or neurological disorders was consistent. Patients with suspected neurosyphilis or patients with neurological signs compatible with neurosyphilis (who did not undergo CSF examination) were treated with adequate neurosyphilitic therapy.

Abstract
An indirect Treponema pallidum-IgG enzyme-linked immunosorbent assay (Tp-IgG-ELISA) was used for the estimation of intrathecal synthesis of specific IgG antibodies in patients with syphilis. Detection of T. pallidum DNA in cerebrospinal fluid (CSF) samples of syphilitic patients was performed by amplification of treponemal DNA, using the polymerase chain reaction (PCR). Both methods were compared as to their suitability for diagnosis of neurosyphilis in 37 patients with syphilis. Intrathecal synthesis of T. pallidum-specific IgG and PCR was negative in 16 patients with treated syphilis or untreated secondary syphilis. In contrast, an intrathecal IgG antibody production was found in all 21 patients with treated or untreated neurosyphilis. PCR was only positive in CSF samples from six out of ten patients with untreated neurosyphilis. The findings suggest that the intrathecal production of T. pallidum-specific IgG antibodies is an important indicator for the diagnosis of neurosyphilis. In addition, a positive result by PCR performed in CSF establishes a diagnosis of active neurosyphilis.

Abstract
The sensitivity of six different ELISA techniques and calculation methods for the determination of intrathecal synthesis of IgG antibodies specific to Borrelia burgdorferi was investigated in paired CSF and serum specimens from 33 patients with neuroborreliosis. The diagnostic value of the Antibody Index (AI) was compared with the meaningfulness of serum antibodies to B. burgdorferi (Bb), established by immunofluorescence assay (IFA). The AI, as a standard for intrathecal antibody synthesis was determined from specific antibody ratios (QBb) in the CSF and serum and the CSF/serum ratio of IgG (QIgG) or albumin (QAlb). Using Western blotting with identical concentrations of IgG in the CSF and serum all patients displayed intrathecal synthesis of specific antibodies to at least two B. burgdorferi proteins. The different ELISA methods and calculation procedures were almost equivalent in demonstrating intrathecal synthesis of specific antibodies (32 and 33/33). Calculation of AI from IFA titers was somewhat less sensitive (30/33). In 5 patients titers of serum IgG- and IgM-antibodies to B. burgdorferi determined by IFA were within the normal range or borderline, while elevated AIBb values indicated an autochthonous immune response to B. burgdorferi in the CSF. In uncertain cases of neuroborreliosis calculation of AI from ELISA titers will be useful in clarifying the diagnosis.

Abstract
The antibody specificity index (ASI) indicates the cerebrospinal fluid (CSF)/serum difference of antibody amounts per weight unit IgG (normal less than 1.5). It has proven to be the most sensitive inflammation parameter in CSF analysis so far, more sensitive than the Western blot, the "oligoclonal" response, and the empirical differentiation of CSF immunoglobulins. By this diagnostic criterion, several benign viral meningitis cases were found to be caused by the varicella/zoster virus. The diagnostic relevance of local zoster antibody synthesis was greatest in ganglionitis cases, e.g., in zoster oticus sine herpete (facial paresis) and acute radicular syndromes of the elderly. The diagnostic significance of the local immune response against measles, rubella, and zoster antigens (MRZ response) was ascertained further. Together with oligoclonal gamma-globulin fractionation, there is now only 1 out of 100 multiple sclerosis (MS) patients left who has been found to have a normal CSF.

Abstract
Of the 96 serologically confirmed neuroborreliosis cases seen in our clinic between 1983 and 1988, 11 patients had mild to moderate and 4 patients had serious cerebral and/or spinal cord symptoms. Nine of these 15 patients with CNS involvement exhibited a primary chronic course of the illness. After high-dose intravenous therapy with penicillin, doxycycline or cefotaxime, given mostly in combination with cortisone, gradual recovery occurred with normalization of CSF findings characteristic of neuroborreliosis, and normalization of significantly elevated Borrelia burgdorferi IgG antibody titres in CSF and serum. Brain MRI and CT showed evidence of or were suggestive of vascular involvement which correlated with clinical symptoms in 11 of the 15 patients with CNS involvement. Brain MRI changes that were similar but much slighter in number and intensity were seen in 5 of 12 neuroborreliosis patients without clinical signs of CNS involvement (lymphocytic meningoradiculitis; Bannwarth's syndrome). The frequencies of the HLA-DR7 (75%), HLA-B44 (50%) and HLA-A29 (33%) antigens in 12 neuroborreliosis patients with clinical symptoms of CNS involvement were significantly different from the frequencies in 12 neuroborreliosis patients without CNS involvement and in 100 control subjects. Diagnostic criteria of active neuroborreliosis are proposed.

Abstract
An antibody capture enzyme-linked immunosorbent assay was developed to measure directly intrathecal immunoglobulin (Ig) G, A, and M synthesis specific for Borrelia burgdorferi. Purified, biotin-avidin-peroxidase-labeled B. burgdorferi flagella was used as test antigen. Paired cerebrospinal fluid and serum specimens from 100 patients with clinically definite neuroborreliosis and 35 control subjects with neurological diseases were examined. Significant B. burgdorferi-specific intrathecal IgG, A, and M production was found in 89%, 65% and 67% of patients with neuroborreliosis. Local synthesis of specific IgA was only seen in patients with significant local IgG synthesis. Antibody production in cerebrospinal fluid began by 2 weeks after onset of neurological symptoms. At the end of the second week specific IgM, IgG, or both, was detected in 88% of the patients. Specific IgG synthesis was present in all patients by 6 weeks after onset. Specific local IgM synthesis usually disappeared by 3 to 6 months after therapy, whereas specific IgG synthesis persisted after recovery. Even in patients with a severely altered blood-brain barrier, the assay discriminated between intrathecal antibody synthesis and antibody leakage from serum. The assay makes diagnostic measurement of B. burgdorferi-specific intrathecal antibody synthesis reliable, rapid, and accessible as a routine serological test.

Abstract
We evaluated occurrence and levels of intrathecal synthesis of IgG, IgM, IgA and IgD by calculating corresponding index values in 8 patients with definite and 4 with suspected or possible neurosyphilis, prior to, during and after high-dose intravenous penicillin therapy. Four patients with active neurosyphilis displayed intrathecal synthesis of IgG, IgM and IgA. Only 2 of them showed elevated IgD index, and both had taboparesis, pleocytosis and positive VDRL in CSF, and simultaneous elevation of the IgG, IgA and especially of the IgM indices. This suggests that intrathecal synthesis of IgD may occur in patients with severe CNS inflammation in response to diffuse CNS treponemal damage. Penicillin therapy incited transitory elevation of one or more of the immunoglobulin index values in most patients, possibly in response to massive treponemal lysis inside the CNS. Thereafter, the values became mostly normalized but exceptions occurred, including one patient who had elevated IgG and IgM index which persisted 31 months after therapy. Our data indicate that determinations of immunoglobulin indices performed on consecutive specimens from individual patients with neurosyphilis may be helpful in the evaluation of treatment.

Abstract
Follow-up studies on 56 patients who suffered from antibiotically untreated, acute, monophasic neuroborreliosis five to 23 years ago revealed significant positive levels of IgG antibodies to Borrelia burgdorferi (Bb) in the serum and cerebrospinal fluid (CSF) of 20 patients (IFT, ELISA, Bb-specific IgG Western blot, Bb-specific IEF-IgG immunoblot). Nine of 10 tested patients had a definitely positive T-cell proliferative response to whole B. burgdorferi, with a mean (+/- -SEM) stimulation index of 7.2 +/- 1.8. Because the patients studied exhibited no, or only mild to medium sequelae without any evidence of a chronic-progressive disease, we interpret the long-term persistence of specific T- and B-lymphocyte responses to B. burgdorferi as an "immunological scar syndrome". Finally, diagnostic criteria of active neuroborreliosis are proposed.

Abstract
Cerebrospinal fluid (CSF) and serum samples from six patients with enterovirus infections were investigated by isoelectric focusing (IEF) and affinity-mediated immunoblot AMI) for the clonal distribution of entervirus-specific antibodies. In two patients with either acute meningitis or encephalitis and in one patient with a relapse of multiple sclerosis, oligoclonal IgG bands specific for enteroviruses were found predominantly in the CSF, revealing intrathecal synthesis of these antibodies. In three other patients with neurological symptoms probably unrelated to a current enterovirus infection, IEF and AMI disclosed nearly identical patterns of coxsackievirus-B-specific oligoclonal bands in the CSF and serum, indicating diffusion of these antibodies from the serum into the CSF. Although the number of patients in this study is small, the results suggest that intrathecally synthesized enterovirus-specific antibodies may be used as a means of identifying an enterovirus infection of the CNS.

Abstract
In 1987, follow-up studies were conducted on 72 patients who had had meningoradiculitis and encephalomyelitis (8 patients) due to Borrelia burgdorferi 5-27 years previously. These patients had not been treated with antibiotics, either during the acute disease or during the interval prior to follow-up studies. The patients had exhibited the typical symptoms of Bannwarth's syndrome during the acute phase. At the follow-up studies, 33 patients showed no, and 23 only mild, clinical residual symptoms including normal CSF findings and low-positive serum IgG borrelia antibody titres (IFT; ELISA). Three patients without sequelae exhibited persistent intrathecal secretion of oligoclonal B. burgdorferi-specific CSF IgG antibodies (Immunoblot; positive borrelia CSF IgG antibody titres). Thirteen patients exhibited mild-to-medium sequelae with persistent intrathecal formation of oligoclonal B. burgdorferi-specific CSF IgG antibodies, up to 21 years after the acute illness. This persistence can be interpreted as an "immunological scar syndrome". Our follow-up studies appear to indicate that neurological manifestations of B. burgdorferi infections are generally (with few exceptions) of a benign nature. Most patients can be classified as having been cured without antibiotic therapy. No late manifestations of chronic progressive CNS borreliosis comparable to that of neurosyphilis have been seen following acute untreated neuroborreliosis.

Abstract
Patients with syphilitic infections are at risk of development of symptomatic neurosyphilis. Adequate treatment with 2.4-7.2 x 10(6) units benzyl penicillin-G intramuscularly within 1 year after infection will rule out this risk. However, more than 1 year after infection this treatment is not fully reliable. In asymptomatic CNS involvement (asymptomatic neurosyphilis) only intravenous penicillin treatment is considered to be adequate in the prevention of neurosyphilis. In this study we redefined criteria for this condition by comparing serum and cerebrospinal fluid (CSF) samples of symptomatic neurosyphilitic patients with those of latent syphilitic patients without CNS involvement. Diagnostic criteria of the World Health Organization and of Centers of Disease Control for asymptomatic neurosyphilis (positive CSF Venereal Disease Research Laboratory (VDRL) test, combined with raised CSF cell count and/or protein content) were studied and compared with some newer parameters such as signs of intrathecal treponemal antibody production (Treponema pallidum haemagglutination assay and intrathecal Treponema pallidum assay index), immunoglobulin G (IgG) and M (IgM) index. The results of this study in 203 syphilitic patients revealed that either a positive CSF-VDRL or combination of a raised IgG and/or IgM index with an elevated CSF cell count both are useful criteria for "ruling-in" asymptomatic neurosyphilis.

Abstract
Penicillin concentrations in cerebrospinal fluid (CSF) were measured in 40 asymptomatic patients with syphilis, 10 of whom had neurosyphilis. The patients were treated with 2.4 MIU procaine penicillin a day intramuscularly in combination with 500 mg probenecid every six hours orally. This intramuscular treatment regimen did not consistently yield treponemicidal penicillin concentrations in the CSF (subtreponemicidal CSF concentrations were found in 17 patients, four of whom had neurosyphilis). These data provide additional evidence that the cure of asymptomatic neurosyphilis is not guaranteed by intramuscular penicillin treatment.

Abstract
Treponemal-antigen-eliciting antibodies in neurosyphilis were investigated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis immunoblotting with 17 sera and cerebrospinal fluid (CSF) (16 pairs) from 10 neurosyphilitic patients. Sera and CSF detected identical proteins. IgG antibodies in sera and CSF mainly revealed Treponema pallidum proteins of MW 48, 45, 38 and 37 Kd, and T. phagedenis proteins of MW 59, 54, 41, 40, 35 and 33 Kd. Few proteins were detected by IgM antibodies. Although no particular protein elicited antibodies specific for neurosyphilis, the immunoblot detection of antibodies to T. pallidum or T. phagedenis antigens in CSF or sera should be useful as a diagnostic tool for neurosyphilis.

Abstract
Sixty-two patients with symptomatic neurosyphilis were treated with 20 or 24 megaunits of intravenous penicillin G daily for 15 to 30 days. The mean follow-up time after the treatment was 30 months. Forty-one patients had pleocytosis in the CSF before treatment. Six months and twelve or more months later, abnormal cell count was observed in 4 (9.8%) and in 3 patients (7.3%), respectively. The CSF protein level and the titers of Wassermann reaction in the CSF decreased slowly after treatment. The gammaglobulin concentration of the CSF and the immunoglobulin production inside the blood-brain barrier were still increased beyond the first year after treatment. The results of the treatment of these patients with high doses of intravenous penicillin G were not different from the results verified with lesser doses of intramuscular penicillin that were reported in the literature.

Abstract
Neurological examination and investigation of the cerebrospinal fluid (CSF) was performed on 24 patients with early and 180 patients with late syphilis. In 21 (12%) patients with late syphilis positive CSF treponemal test results and neurological deficits suggestive of symptomatic neurosyphilis were found. Concomitantly all but three patients with neurosyphilis showed one or more of the following abnormal CSF variables: CSF concentration of albumin X 10(3)/serum concentration (albumin ratio) greater than or equal to 7.9; mononuclear cells greater than 5 microliters: ratio of CSF to serum IgG concentrations/ratio of CSF to serum albumin concentrations (IgG index) greater than or equal to 0.7 or of IgM/albumin (IgM index) greater than or equal to 0.1; or oligoclonal CSF immunoglobulins. In 20 (95%) patients with neurosyphilis evidence of the production of treponemal antibodies within the central nervous system (CNS) was shown. Ten (48%) patients with neurosyphilis had been treated previously for late syphilis. These observations emphasise the need to screen for neurosyphilis in patients with late syphilis. Intrathecal production of treponemal antibodies was detected in six (25%) patients with early and 44 (28%) with late syphilis who did not show any neurological deficit. Intrathecal production of treponemal antibodies indicating that the CNS was affected led us to suspect asymptomatic neurosyphilis in these patients. Seventeen (11%) patients with late syphilis but no neurosyphilis and only one (4%) with early syphilis showed additional abnormal CSF variables. Surprisingly, six out of 22 patients with treated early and 20 out of 68 patients with treated late syphilis showed evidence of treponema antibody production within the CNS. We do not know whether these findings indicate that the CNS was affected because of inadequate treatment or merely reflect persistent synthesis of treponemal antibodies associated with cured infection. In one (4%) patient with early and in 21 (13%) with late syphilis but no neurosyphilis abnormal CSF variables in the absence of positive CSF treponemal test results were observed, which excluded syphilitic inflammation of the CNS.

Abstract
Anti-myelin antibodies (AMA) of IgG, IgM, and IgA class were investigated by ELISA in CSF and serum from patients with meningopolyneuritis Garin-Bujadoux-Bannwarth (GBB), other inflammatory diseases of the nervous system (ID) comprising meningoencephalitis (ME), multiple sclerosis (MS), and Guillain-Barré syndrome (GBS), and various noninflammatory neurological diseases (NID). Anti-Borrelia antibodies (ABA) were determined by ELISA in GBB patients. In CSF, a high incidence of IgG-AMA, IgM-AMA, and IgA-AMA was found in GBB as compared with ID and NID. On average, positive AMA titers were higher in GBB than in ID and NID, IgM-AMA titers in GBB being most prominent. In serum, AMA were found in all but 2 patients investigated. On average, IgM-AMA titers were higher in GBB and MS than in other diseases; IgG-AMA titers in GBB and ME were relatively low. Antibody indices, calculated from titer values and Ig concentrations in CSF and serum, indicate intrathecal synthesis mainly of IgG- and IgA-AMA, and of IgG- and IgM-ABA. Participation of AMA in the pathogenesis of GBB may be envisaged, but needs further confirmation.

Abstract
Immunoglobulin M (IgM) antibodies to Treponema pallidum (TP) in serum and cerebrospinal fluid (CSF) can be evaluated quantitatively using a recently introduced enzyme-linked immunosorbent assay (ELISA). In 19 patients with untreated neurosyphilis, local synthesis of TP-specific IgM antibodies within the central nervous system (CNS) was demonstrated by estimation of the CSF/serum ratio of the TP-IgM-ELISA titer/mg total IgM. The TP-specific IgM antibody levels/mg total IgM in the CSF were between 3- and 75-fold higher than those in the corresponding serum of the same patients. Patients with untreated syphilis but without CNS involvement showed equal amounts of TP-specific IgM antibody levels/mg total IgM in CSF and serum, and served as controls.
