Background: Syphilis is a major public health issue worldwide. In people living with human immunodeficiency virus (PLHIV), there are higher incidences of both syphilis and neurosyphilis. The criteria for referring PLHIV with syphilis for lumbar puncture is controversial, and the diagnosis of neurosyphilis is challenging., Objective: To describe the knowledge, attitudes, and practices of infectious disease specialists and residents in the context of care for asymptomatic HIV-syphilis coinfection using close-ended questions and case vignettes., Design and Setting: Cross-sectional study conducted in three public health institutions in São Paulo (SP), Brazil., Methods: In this cross-sectional study, we invited infectious disease specialists and residents at three academic healthcare institutions to answer a self-completion questionnaire available online or in paper form., Results: Of 98 participants, only 23.5% provided answers that were in line with the current Brazilian recommendation. Most participants believed that the criteria for lumbar puncture should be extended for people living with HIV with low CD4+ cell counts (52.0%); in addition, participants also believed that late latent syphilis (29.6%) and Venereal Disease Research Laboratory (VDRL) titers ≥ 1:32 (22.4%) should be conditions for lumbar puncture in PLHIV with no neurologic symptoms., Conclusion: This study highlights heterogeneities in the clinical management of HIV-syphilis coinfection. Most infectious disease specialists still consider syphilis stage, VDRL titers and CD4+ cell counts as important parameters when deciding which patients need lumbar puncture for investigating neurosyphilis.

Objective: Our objective was to describe and compare the occurrence of neurological outcomes and neurosyphilis in people living with HIV with incident syphilis and no neurological symptoms who underwent early screening for asymptomatic neurosyphilis (ANS) or regular clinical management without a lumbar puncture., Methods: This was a retrospective cohort study in a single referral centre of Sao Paulo, Brazil. Patients with incident syphilis diagnosed between January 2000 and August 2016 and meeting the adapted criteria for ANS investigation suggested by Marra et al. (CD4 + T-cell counts ≤350 cells/mm³ and/or venereal disease research laboratory test results ≥1:16) were identified. Those with no neurological symptoms and immediately referred for lumbar puncture were categorized as group 1, and those not referred for cerebrospinal fluid collection were categorized as group 2. We compared the occurrence of neurological symptoms and neurosyphilis diagnoses between the groups using incidence rates and Kaplan-Meier curves., Results: We included 425 participants with a median follow-up of 6 years. The incidence rate of neurological symptoms was 36.5/1000 person-years in group 1 and 40.6/1000 person-years in group 2 (incidence rate ratio [IRR] 0.90; 95% confidence interval [CI] 0.57-1.39; p = 0.62). The incidence rate of neurosyphilis was 15.0 cases/1000 person-years in group 1 and 6.7 cases/1000 person-years in group 2 (IRR 2.26; 95% CI 0.93-5.68; p = 0.05)., Conclusions: We found no statistically significant differences between groups in the incidence rates of neurological symptoms and neurosyphilis. Our findings support the current guidelines, which suggest a less invasive approach regarding ANS investigation among people living with HIV with incident syphilis., (© 2022 British HIV Association.)

Syphilis is a public health problem, especially in pregnant women, due to the risk of transmission to the fetus and the involvement of the central nervous system, causing neurosyphilis. A case-control study was carried out to analyze the variables associated with neurosyphilis in Brazilian newborns of pregnant women with syphilis admitted for childbirth. Newborns were submitted to treponemal and non-treponemal tests, cerebrospinal fluid analysis, and long bone radiography. Newborns diagnosed with neurosyphilis and congenital syphilis were defined as cases and controls, respectively. The length of hospitalization and mean cost of neurosyphilis treatment were also evaluated. Twenty-one cases of newborns with neurosyphilis and 42 controls with congenital syphilis were included in the study. Out of 63 pregnant women with syphilis, 95.2% (60/63) received prenatal care, 74.6% (47/63) were diagnosed with syphilis during this period, 31.9% (15/47) underwent treponemic tests, 80.8% (38/47) were treated with penicillin and only 46.8% (22/47) of the partners received the treatment. Clinical complications such as low birth weight were observed in 12.7% (8/63) of the newborns. About 50.8% (32/63) of the newborns were hospitalized due to syphilis complications and each case of neurosyphilis spent at least US$ 881.48 on treatment and hospitalization. The results showed that the prenatal coverage is not sufficient to prevent neurosyphilis. The late diagnosis of syphilis in pregnant women and inadequate follow-up of sexual partners may favor the vertical transmission of T. pallidum in pregnant Brazilian women. Thus, improving the quality of health services is important for a more effective control of neurosyphilis.

Background and Aims: Syphilis and stroke are high prevalent diseases in south Brazil and estimates of concomitance and possible role of syphilis in acute stroke are lacking. Our aims are to estimate the prevalence of syphilis and neurosyphilis (NS) in a cohort of tertiary stroke center., Methods: We reviewed all hospital records of stroke/transitory ischemic attack (TIA) using International Classification of Diseases, 10th revision, at discharge, frequency of syphilis screen, serology positivity, cerebrospinal fluid (CSF) analysis, and prevalence of NS in this stroke population applying CDC criteria., Results: Between 2015 and 2016, there were 1,436 discharges for cerebrovascular events and in 78% (1,119) of these cases, some syphilis screening was performed. We have found a frequency of positive serology for syphilis of 13% (143/1,119), and higher stroke severity was the main determinant for non-screening. Applying standard NS criteria, 4.7% (53/1,119) cases with CSF analysis had NS diagnosis: 8 based on CSF-Venereal Disease Research Laboratory (VDRL) positive and 45 based on abnormal CSF white cells or protein, but CSF VDRL negative. NS VDRL positive cases were younger, had higher serum VDRL title, had more frequent HIV infection, and received NS treatment more often. Demographic and clinical characteristics were not different between NS VDRL negative and non-NS cases., Conclusion: Positive syphilis serology is frequent in patients with acute stroke/TIA in our region. Acute post-stroke CSF abnormalities make the diagnosis of NS difficult in the context of CSF VDRL negative., (© 2020 S. Karger AG, Basel.)

Goal: To describe clinical and laboratory features of human immunodeficiency infection (HIV)-infected patients with neurosyphilis., Study Design: Retrospective study of 27 consecutive cases of HIV-infected patients with a positive Venereal Disease Research Laboratory (VDRL) in cerebrospinal fluid (CSF)., Results: Median of age was 36 years and 89% were men. Ten (37%) patients had previous nonneurologic syphilis treatment. At the time of neurosyphilis diagnosis, 10 (37%) patients had early syphilis, and 6 of them were neurologically asymptomatic. Nine (33%) patients had symptomatic neurosyphilis. Twenty-six (96%) patients were classified with early neurosyphilis. The medians of serum VDRL and CD4 T cell counts were 1:128 and 182 cell/muL, respectively. Twenty five (93%) patients presented serum VDRL titers > or =1:16. Five of 6 patients with early syphilis and asymptomatic neurosyphilis, presented serum VDRL > or =1:16. Symptomatic patients showed lower CD4 T cell counts (59 cell/muL vs. 208 cell/muL, P = 0.03) and higher protein concentration on CSF (118 mg/dL vs. 39 mg/dL, P <0.001) than asymptomatic patients., Conclusions: Most patients had early and asymptomatic neurosyphilis, and more than one third had early syphilis. Patients with symptomatic neurosyphilis showed lower CD4 T cell counts and higher protein concentration on CSF than those asymptomatic. Most patients had serum VDRL titers > or =1:16, regardless of syphilis stage.

The importance of investigating the etiology for dementia lies in the possibility of treating potentially reversible dementias. The aims of this retrospective study are to determine the prevalence of potentially reversible dementias among 454 outpatients seen at the Cognitive and Behavioral Neurology Unit, Hospital das Clínicas, São Paulo University School of Medicine-Brazil, between the years of 1991 and 2001, and observe their evolution in follow-up. Among the initial 454 patients, 275 fulfilled the DSM-IV criteria for dementia. Alzheimer's disease was the most frequent diagnosis (164 cases; 59.6%). Twenty-two cases (8.0%) of potentially reversible dementia were observed, the most frequent diagnoses being neurosyphilis (nine cases) and hydrocephalus (six cases). Full recovery was observed in two patients and partial recovery in 10 patients. Two cases were not treated and eight cases were lost on follow-up. The prevalence found in the present study falls within the range reported in previous studies (0-30%).

After 1950 it was observed an increase in the incidence of syphilis in the general population and this fact determined an investigation in order to evaluate the possible repercussion of this occurrence on the central nervous system, as an after effect of the elevated incidence. However, in this first study it was verified that there was a progressive and marked decrease of the neurosyphilis incidence in the 1936-1964 period, and that the frequency of meningovascular forms of the disease had increased lately in regard to the parenchymatous forms. The aim of the present work has been the continuation of this study after so many years. The material for this survey consisted of the clinical records of 148 patients picked out from 34.430 cases seen at the Neurological Department of Escola Paulista de Medicina (São Paulo, Brasil), during the 1962-1981 period, i.e., on twenty consecutive years. The results of this complementary investigation have shown instead that the incidence of neurosyphilis remained steady, changing very little every year, with an incidence at the rate of about 1:200. On the other hand, the frequency of the clinical forms of neurosyphilis changed very much. The usual forms such as general paresis and tabes are now scant and the observation of the uncommon forms, seldom seen in the past, is now progressively increasing through the years, so that they are the preponderant clinical forms today.

Through informations obtained at the statistical and medical register service, it was done a descriptive study of some epidemiological aspects of neurosyphilis and general progressive paralysis at the Juliano Moreira Hospital, Bahia, Brasil, in a period of 50 years (1930-1979). For this purpose medical dossiers, obituaries, ingoing and outgoing register books, the census and nosocomial bulletin were referred. The distribution of disease was analysed comparing profession and origin according to sex, diagnosis, decade and time before and after penicillin therapy. The results allowed us to conclude that: a) The professions that we found more frequently were: formers, merchants, housewives, stoneworkers, public officials, tailors, soldiers, shoemakers, laborer workers; b) During the periods of war, we observed an increase in the number of ill soldiers; c) Patients coming from the urban zone were more frequently affected by the disease.
