Understanding the extent of and limitations to conscientious objection to abortion by health care practitioners: A hermeneutic study.

The United Kingdom's Abortion Act 1967 has attracted substantial controversy, which has centred not only on the regulation of abortion itself, but also on the extent to which conscientious objection should be permitted. The aim of this study was to examine a range of healthcare professionals' views on conscientious objection and identify the appropriate parameters of conscientious objection to abortion. Gadamer's hermeneutic was utilised to frame this study. We conducted semi-structured interviews in two UK locations with 18 pharmacists, 17 midwives, 12 nurses and nine doctors, encompassing a mix of conscientious objectors and non-objectors to abortion. A multi-faceted in-depth data analysis led to the development of a hermeneutic of "respecting self and others". Four major themes of "doing the job", "entrusting to others", "acknowledging institutional power" and "being selective" and 18 subthemes contributed to this overarching theme. The complexity of the responses indicates that there is little consistency within and between each profession. They show that participants who were conscientious objectors were accepted by their colleagues and accommodated without detriment to the service, and that in larger hospitals, such as those where our work was carried out, it is possible to be employed in the service areas that include abortion while still being a conscientious objector. Finally, our results indicate that, by respecting of self and others, each profession should be able to accommodate conscience-based objections where individual practitioners seek to exercise them. Conscientious objectors as well as non-objectors have something to contribute to the ongoing development of the maternity and gynaecological services as abortion is only a small part of the work of these services.

The missing voices in the conscientious objection debate: British service users' experiences of conscientious objection to abortion.

BACKGROUND: The fourth section of the 1967 Abortion Act states that individuals (including health care practitioners) do not have to participate in an abortion if they have a conscientious objection. A conscientious objection is a refusal to participate in abortion on the grounds of conscience. This may be informed by religious, moral, philosophical, ethical, or personal beliefs. Currently, there is very little investigation into the impact of conscientious objection on service users in Britain. The perspectives of service users are imperative in understanding the real-world consequences and potential impact of conscientious objection and should be considered when creating and reviewing policies and guidelines. This research provided a platform for women and those who can become pregnant to share their experiences and opinions at a time when these voices are largely excluded in the great tradition of Western political philosophy and law-making processes. METHOD: Five service users were interviewed using a narrative interview approach to uncover their abortion journeys and experiences of conscientious objection. FINDINGS: The findings were presented as found poems and uncovered that doctors are not always: informing service users that they have a conscientious objection to abortion, giving service users enough information to access abortion (indirect referral), treating them non-judgmentally, and providing medically correct information. Service users did not experience burdens such as long waiting times and were still able to access legal abortion. However, service users did experience negative emotional effects, as they were often left feeling scared, angry, and hopeless when they were not referred and/or were mistreated. CONCLUSIONS: Findings indicate that conscientious objection could work in practice. However, it is currently failing some individuals on an emotional level, as not all doctors are adhering to guidelines. Conscientious objection in Britain needs to be addressed, to ensure service users receive fair, impartial, non-judgmental care.

Why have a bottle when you can have draught? Exploring bottle refusal by breastfed babies.

Bottle refusal by breastfed babies is a scenario that has received surprisingly little attention in the literature, given the number of mothers who appear to be experiencing it globally and the subsequent negative impact it can have. In line with this, we undertook a study to explore mothers' views on why their breastfed baby refuses to bottle feed. A parallel, two-stage, exploratory qualitative design was employed using 30 semi-structured interviews and 597 online forum posts. Data were analysed using a thematic analysis, and a biopsychosocial model was applied resulting in four overarching themes being identified: 'Breastfeeding is the answer to everything….' 'Bottle feeding: an alien concept… 'Babies are individuals' and 'Find the right bottle and don't delay'. The psychological benefits of breastfeeding, not inherent in bottle feeding, appeared to underpin some mothers' views on their baby's refusal. Other mothers explained refusal as being down to a baby's biological expectation to be fed by the breast; therefore, bottle feeding was not a normal concept to them. A baby's individual personality and temperament were also suggested as contributing to the scenario and refusal was linked to babies disliking a certain brand of bottle and being introduced to it 'too late'. This study's findings point to a complex, multifactorial picture underpinning bottle refusal by breastfed babies, which transcends physical, psychological and biological concepts, and is influenced by socio-cultural norms surrounding infant feeding. Recognition of these contributing factors is needed to aid those supporting mothers experiencing the scenario and, importantly, to underpin mothers' decision-making around managing it.

It's about finding a balance exploring conscientious objection to abortion with UK midwives.

BACKGROUND: Despite the right for health professionals to abstain from providing abortion services existing for over 50 years, literature on conscientious objection to abortion scarcely mentions midwives. In addition, little empirical research has been carried out concerning midwives' views surrounding what constitutes participation in abortion and in turn, what areas of care they can withdraw from. AIM: To explore midwives' beliefs regarding the extent of and limitations to the exercising of their legal right to objection to abortion on conscience grounds. DESIGN: Qualitative study with 17 midwives in Glasgow and Liverpool, UK. METHOD: Face to face semi-structured interviews, transcribed verbatim and analysed using a thematic analysis and Human Rights framework for midwifery care. FINDINGS: The extent of and limitations to CO to abortion-related care was reflected in four themes: respecting and protecting, making informed decisions, providing non-discriminatory care and experience and culture. There was an overriding sense of support for midwives to be able to exercise their right to conscientious objection, how this is operationalised in practice however continues to be fraught with complexity, which in turn poses constant challenges to midwives who object, their colleagues and managers. CONCLUSIONS: Midwives' beliefs regarding the exercising of their legal right to object to abortion-related care on conscience grounds can be summarized in the challenge of "finding a balance". A national picture of how to accommodate CO to abortion is needed, so that all midwives can continue to give optimal care to women and receive it themselves, within a human rights framework.

Previous Syphilis Alters the Course of Subsequent Episodes of Syphilis.

BACKGROUND: The influence of previous syphilis on the course of a subsequent episode is unknown. METHODS: Individuals enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis were allowed to enroll in the study again with subsequent syphilis. For each participant, the index episode was defined as the most recent syphilis episode for which the study entry visit was performed within 30 days of the syphilis diagnosis date. Venipuncture and lumbar puncture (LP) were performed. Total number of syphilis episodes was determined by review of medical and public health records. T. pallidum DNA in blood and rRNA in CSF were detected by polymerase chain reaction (PCR) and reverse transcriptase PCR. Odds ratios (ORs) with 95% confidence intervals (95% CI) were determined by logistic regression. RESULTS: 651 individuals had one (n = 482), two (n = 121) or three or more (n = 48) episodes of syphilis. The proportion of individuals whose index episode was early latent stage was significantly higher in those with ≥3 syphilis episodes; this relationship was reduced to a trend when rate of testing was taken into account. Adjusted odds (aOR) of detection of T. pallidum DNA in blood or rRNA in CSF at the index episode were significantly lower in those with previous syphilis (0.17 [95% CI, 0.09-0.31] and 0.15 [95% CI, 0.07-0.35]). The aOR for neurosyphilis at the index episode was also significantly lower in individuals with previous syphilis (0.54 [95% CI, 0.34-0.87]). CONCLUSIONS: Previous syphilis attenuates the manifestations of subsequent infection with T. pallidum.

Cognitive impairment in syphilis: Does treatment based on cerebrospinal fluid analysis improve outcome?

BACKGROUND: Individuals with previous syphilis may experience cognitive impairment. The goal of this study was to determine if those at high risk for laboratory-defined neurosyphilis are cognitively impaired, and whether treatment based on cerebrospinal fluid (CSF) findings results in better outcomes. METHODS: Participants had a new syphilis diagnosis, serum RPR titer ≥ 1:32 or peripheral blood CD4+ T cells ≤ 350/ul (in persons living with HIV) and did not endorse neurological symptoms. They underwent computerized cognitive assessment with the CogState. Thirty-two were randomized to either undergo lumbar puncture (LP) or to not undergo LP and 14 underwent LP; 64 were not randomized and 48 opted to undergo LP. RESULTS: Demographics, cognitive complaints and cognitive impairment did not differ between randomized and nonrandomized participants. Two-thirds were cognitively impaired, and impairment was not more common in those with cognitive complaints. The adjusted odds of increased severity of impairment were 3.8 times greater in those with CSF pleocytosis compared to those without. Time to cognitive normalization, improvement or decline did not differ between those who did not undergo LP and those who underwent LP and whose treatment was based on CSF analysis. Taking into account pre-treatment cognitive impairment, the risk of cognitive decline was lower in those with CSF pleocytosis treated for neurosyphilis compared to those without CSF pleocytosis not treated for neurosyphilis, (HR 0.24 (95% CI 0.07-0.88], p = 0.03). CONCLUSION: In individuals at high risk for laboratory-defined neurosyphilis, cognitive complaints are not a good indicator of cognitive impairment. Severity of cognitive impairment was greater in those with CSF pleocytosis. Identification and treatment of those with neurosyphilis may mitigate subsequent cognitive decline.

Exploring pharmacists' views surrounding conscientious objection to abortion and implications in practice.

BACKGROUND: General Pharmaceutical Council standards (UK) state 'pharmacy professionals have the right to practise in line with their religion, personal values or beliefs as long as they …make sure that person-centred care is not compromised', indicating a potential conflict for pharmacists who wish to exercise their right to conscientious objection (CO) to abortion while maintaining a duty of care to their patients. OBJECTIVE: The objective of this study was to explore pharmacists' views of conscientious objection to abortion and whether this included the supply of EC and the impact on practice. METHOD: Eighteen UK pharmacists were interviewed using semistructured interviews. Interviews were transcribed verbatim, imported into NVivo11 and analysed using thematic analysis. KEY FINDINGS: Five themes were identified: beliefs as to what constitutes abortion, influences on beliefs, conflicts of conscience, accommodating conscience and professional obligations. Views were polarised in relation to the role of emergency contraception (EC) as an abortifacient. Religion was often viewed as the reason underpinning CO to abortion. Conflicts in relation to CO to abortion included the role of referral and EC and employability for objectors. Some pharmacists viewed their role of providing patient choice as incompatible with the right of CO to abortion. CONCLUSIONS: This study shows the conflicts and challenges surrounding CO to abortion in professional pharmacy practice. While the majority of pharmacists believe CO to abortion should and could be accommodated, this can prove challenging in certain working environments, both in relation to ensuring a duty of care to patients is upheld and due to the ongoing debate concerning EC and whether it has a definitive role in abortion or not.

Hearing loss in individuals at risk for neurosyphilis.

Otosyphilis is a serious complication of syphilis.329 participants enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis underwent portable audiometry (250 Hz to 8000 Hz at 5-75 dB); it was repeated in 33 after otosyphilis treatment. Treponema pallidum spp pallidum (T. pallidum) DNA in blood was quantitated by polymerase chain reaction. Odds ratios (ORs) or hazard ratios (HRs) with 95% confidence intervals (CIs) were determined by logistic, ordinal or Cox regression.166 (50.5%) had normal hearing; 15 (4.6%) had low frequency (LF) loss alone, 93 (28.3%) had high frequency (HF) loss alone, and 55 (16.7%) had both. Adjusted odds of any hearing loss were higher with detectable blood T. pallidum DNA (3.00 [1.58-5.69], p = 0.001), CSF pleocytosis (2.02 [1.12-3.66], p = 0.02), and older age (2.22 per 10-year increase, [1.70-2.91], p < 0.001). HRs of normalization of LF and HF loss were lower for older individuals (0.20 [0.07-0.63, p = 0.005] and 0.22 [0.05-0.94, p = 0.04]), and HRs for normalization of HF loss were lower for those with more severe loss (0.09 [0.02-0.43], p = 0.002), and in those with CSF pleocytosis (0.32 [0.11-0.96], p = 0.04).Older age and CSF pleocytosis increase the likelihood of otosyphilis and impair hearing recovery after otosyphilis treatment.

Accommodating conscientious objection in the midwifery workforce: a ratio-data analysis of midwives, birth and late abortions in 18 European countries in 2016.

BACKGROUND: In recent years, the role of a midwife has expanded to include the provision of abortion-related care. The laws on abortion in many European countries allow for those who hold a conscientious objection to participating to refrain from such participation. However, some writers have expressed concerns that this may have a detrimental effect on the workforce and limit women's access to the service. METHOD: The aim of this study was to provide a picture of the potential exposure midwives in Europe have to late abortions, an important factor in the integration of accommodation of conscientious objection to abortion by midwives into workload planning. We collected data from Ministries of Health or government statistical departments in 32 European countries on numbers of births, abortions, late abortions and midwives in 2016. We conducted a ratio-data analysis in those countries that met the inclusion criteria. RESULTS: Eighteen of the 32 countries provided full data; thus, our calculations are based on a total of 4 036 633 live births, 49 834 late abortions and a total of 132 071 midwives. The calculated ratios of live births to midwife, abortions to midwife and late abortions to midwife illustrate the wide variations between countries in relation to ratios of midwives to live births (15.22-53.99) and late abortions (0.17-1.47) CONCLUSIONS: This study provides the first comprehensive insight to ratios relating to birth and abortion, especially late abortion services, with regard to the midwifery workforce. It is essential to improve the reporting of abortion data and access to it within Europe to support evidence-informed decisions on optimising the contribution of the midwifery workforce especially within highly contentious fields such as abortion services. The study's findings suggest that there should be neither be any difficulty for those who are responsible for workload allocation nor compromises to a women's right to abortion services.

UK mothers' experiences of bottle refusal by their breastfed baby.

Little is known about bottle refusal by breastfed babies; however, an informal review of global online forums and social media suggested large numbers of mothers experiencing the scenario. This study aimed to explore UK mothers' experiences of bottle refusal by their breastfed baby in order to provide understanding of the scenario and enhance support for mothers experiencing it. A 22-point online questionnaire was developed and completed by 841 UK mothers. Findings suggest that mothers introduced a bottle to their breastfed baby due to physical, psychological and socio-cultural factors. Advice and support for mothers experiencing bottle refusal was not always helpful, and 27% of mothers reported bottle refusal as having a negative impact on their breastfeeding experience. When compared with eventual bottle acceptance, bottle refusal was significantly associated with previous experience of bottle refusal (p < .001), how frequently mothers intended to feed their baby by bottle and babies being younger at the first attempt to introduce a bottle (p < .001). This study provides a unique insight into the complexities of bottle refusal by breastfed babies and the impact it can have upon mothers' breastfeeding experiences. It generates knowledge and understanding that can help to inform practice and policies. In addition, a 'normalising' of the scenario could enable mothers, and those supporting them, to view and manage it more positively.

Previous Syphilis Alters the Course of Subsequent Episodes of Syphilis.

BACKGROUND: Individuals with previous syphilis may be more likely to be asymptomatic when they are reinfected with Treponema pallidum. METHODS: Individuals enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis were allowed to enroll in the study again with subsequent syphilis. For each participant, the index episode was defined as the most recent syphilis episode for which the study entry visit was performed within 30 days of the syphilis diagnosis date. Venipuncture and lumbar puncture were performed. The total number of syphilis episodes was determined by review of medical and public health records. Treponema pallidum DNA in blood and rRNA in CSF were detected using polymerase chain reaction (PCR) and reverse transcriptase PCR. Odds ratios (ORs) with 95% confidence intervals (CIs) were determined using logistic regression. RESULTS: 701 individuals had 1 (n = 478), 2 (n = 155), or ≥3 (n = 68) episodes of syphilis. The proportion of individuals whose index episode was asymptomatic significantly increased with increased number of syphilis episodes (P < .001). This difference was not explained by frequency of serological tests. Adjusted ORs (aORs) of detection of T. pallidum DNA in blood or rRNA in CSF at the index episode were significantly lower in those with previous syphilis (0.13; 95% CI, .08-.23, and 0.06, 95% CI, .02-.17). The aOR of neurosyphilis at the index episode was also significantly lower in individuals with previous syphilis (0.43; 95% CI, .27-.68). CONCLUSIONS: Previous syphilis attenuates clinical and laboratory manifestations of infection with T. pallidum.

Neurosyphilis Treatment Outcomes After Intravenous Penicillin G Versus Intramuscular Procaine Penicillin Plus Oral Probenecid.

BACKGROUND: Data comparing neurosyphilis treatment regimens are limited. METHODS: Participants were enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis that was conducted at the University of Washington between April 2003 to May 2014. They were diagnosed with syphilis and referred by their providers due to concerns for neurosyphilis. We evaluated 150 people with CSF abnormalities who were treated with either intravenous aqueous penicillin G (PenG) or intramuscular aqueous procaine penicillin G plus oral probenecid (APPG-P). An abnormal CSF diagnosis was defined as a white blood cell (WBC) count >20/µL, a CSF protein reading >50 mg/dL, or a reactive CSF-Venereal Disease Research Laboratory test (VDRL). Hazard ratios for normalization of CSF or serum measures were determined using Cox regression. RESULTS: In individuals treated with either PenG or APPG-P, CSF WBCs and CSF-VDRL reactivity normalized within 12 months after treatment, while protein normalized more slowly and less completely. There was no relationship between treatment regimen or human immunodeficiency virus (HIV) status and likelihood of normalization of any measure. Among those living with HIV, CSF WBC counts and CSF-VDRL reactivity were more likely to normalize in those treated with antiretrovirals. Unexpectedly, CSF WBCs were more likely to normalize in those with low CD4+ T cell counts. When neurosyphilis was more stringently defined as a reactive CSF-VDRL, the relationship with the CD4+ T cell count remained unchanged. CONCLUSIONS: In the current antiretroviral treatment era, neurosyphilis treatment outcomes are not different for PenG and APPG-P, regardless of HIV status. The relationship between the normalization of CSF WBC counts and CD4+ T cell counts may indicate continued imprecision in neurosyphilis diagnostic criteria, due to HIV-related CSF pleocytosis.

Preparing midwifery students for traumatic workplace events: Findings from the POPPY (programme for the prevention of posttraumatic stress disorder in midwifery) feasibility study.

BACKGROUND: Midwifery students can experience events on clinical placements that they perceive to be traumatic. There is currently no requirement to provide training about the nature of trauma, normal responses, or the most helpful ways of self-managing these. The POPPY programme, developed for qualified midwives, incorporates educational (the POPPY workshop) and supportive resources to prevent the development of Post-Traumatic Stress Disorder in midwives. As part of the feasibility evaluation of POPPY, the POPPY workshop element was adapted for pre-registration midwifery students (PreR-POPPY). Attention to this issue during pre-registration education could improve student experience and support student retention. OBJECTIVES: To identify students' perspectives on the contents (clarity, understandability, organisation of the workshop, utility, relevance), their understanding of trauma and psychological responses, and confidence in recognising and managing early signs of distress following participation in a PreR-POPPY workshop. Perspectives on preferred timing in their midwifery programmes, and methods of delivery were also sought. DESIGN: In keeping with educational evaluations, anonymous feedback was collected from students. SETTING: Two higher education institutes. PARTICIPANTS: Midwifery undergraduate students on the three year or shortened programme for registered nurses (n = 131), and midwifery educators (n = 5). METHODS: Students participated in the workshop and provided feedback immediately. Midwifery educators participated in a meeting with the researchers to provide feedback. RESULTS: High levels of satisfaction with the contents of the workshop were identified. Ninety-nine percent of students would recommend the workshop to other midwifery students. Provision of the workshop early in midwifery programmes, revisited at later points, was strongly endorsed. Learning outcomes were very positive for understanding trauma/early stress responses, and recognising and managing early responses to trauma. Strong endorsement for the provision of the workshop was received from the midwifery educators. CONCLUSIONS: The pre-registration adapted POPPY workshop should be routinely provided in preregistration midwifery.

Why Should We Use Online Research Methods? Four Doctoral Health Student Perspectives.

The growth of the Internet has led to an increase in researchers utilizing online methods. Online communities such as forums, blogs, and video platforms are particularly useful for research involving populations that are Internet savvy, seldom heard or discussing sensitive or illicit behavior. Drawing upon the experiences of four doctoral health students who are using online methods, this article discusses the value and benefits of conducting online research as well as the limitations and difficulties encountered. Consideration is given to the methodological and ethical implications of online research. Our own research leads us to reflect on participants' perceptions of what is public, preserving anonymity and protecting participants from harm.

Neurosyphilis Increases Human Immunodeficiency Virus (HIV)-associated Central Nervous System Inflammation but Does Not Explain Cognitive Impairment in HIV-infected Individuals With Syphilis.

BACKGROUND: Individuals infected with human immunodeficiency virus (HIV) who have previously had syphilis may have cognitive impairment. We tested the hypothesis that neurosyphilis causes cognitive impairment in HIV by amplifying HIV-related central nervous system (CNS) inflammation. METHODS: HIV-infected participants enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis underwent the mental alternation test (MAT), venipuncture, and lumbar puncture. CSF concentrations of chemokine (C-X-C motif) ligand 10 (CXCL10), chemokine (C-C motif) ligand 2 (CCL2), and neurofilament light (NFL) were determined by commercial assays. The proportion of peripheral blood mononuclear cells (PBMCs) and of CSF white blood cells (WBCs) that were activated monocytes (CD14+CD16+) was determined by flow cytometry. Neurosyphilis was defined as detection of Treponema pallidum 16S RNA in CSF or CSF white blood cells (WBCs) >20/uL or a reactive CSF-Venereal Disease Research Laboratory (VDRL) test; uncomplicated syphilis was defined as undetectable CSF T. pallidum, CSF WBCs ≤5/uL and nonreactive CSF-VDRL. MAT <18 was considered low. RESULTS: Median proportion of PBMCs that were activated monocytes (16.6 vs. 5.3), and median CSF CXCL10 (10658 vs. 2530 units), CCL2 (519 vs. 337 units) and HIV RNA (727 vs. 50 c/mL) were higher in neurosyphilis than in uncomplicated syphilis (P ≤ .001 for all comparisons). Neurosyphilis was not related to low MAT scores. Participants with low MAT scores had higher median CSF CXCL10 (10299 vs. 3650 units, P = .008) and CCL2 (519 vs. 365 units, P = .04) concentrations than those with high MAT scores. CONCLUSIONS: Neurosyphilis may augment HIV-associated CNS inflammation, but it does not explain cognitive impairment in HIV-infected individuals with syphilis.

Cerebrospinal Fluid Treponema pallidum Particle Agglutination Assay for Neurosyphilis Diagnosis.

Limited data suggest that the cerebrospinal fluid Treponema pallidum particle agglutination assay (CSF-TPPA) is sensitive and a CSF Treponema pallidum hemagglutination assay (CSF-TPHA) titer of ≥1:640 is specific for neurosyphilis diagnosis. CSF-TPPA reactivity and titer were determined for a convenience sample of 191 CSF samples from individuals enrolled in a study of CSF abnormalities in syphilis (training data set). The sensitivity of a reactive test and the specificity for reactivity at serial higher CSF dilutions were determined. Subsequently, CSF-TPPA reactivity at a 1:640 dilution was determined for all available samples from study participants enrolled after the last training sample was collected (validation data set, n = 380). Neurosyphilis was defined as (i) a reactive CSF Venereal Disease Research Laboratory test (CSF-VDRL), (ii) detection of T. pallidum in CSF by reverse transcriptase PCR, or (iii) new vision loss or hearing loss. In the training data set, the diagnostic sensitivities of a reactive CSF fluorescent treponemal antibody absorption test (CSF-FTA-ABS) and a reactive CSF-TPPA did not differ significantly (67 to 98% versus 76 to 95%). The specificity of a CSF-TPPA titer of ≥1:640 was significantly higher than that of lower dilutions and was not significantly different from that of CSF-VDRL. In the validation data set, the diagnostic specificity of a CSF-TPPA titer of ≥1:640 was high and did not differ significantly from that of CSF-VDRL (93 to 94% versus 90 to 91%). Ten CSF samples with a nonreactive CSF-VDRL had a CSF-TPPA titer of ≥1:640. If a CSF-TPPA titer of ≥1:640 was used in addition to a reactive CSF-VDRL, the number of neurosyphilis diagnoses would have increased from 47 to 57 (21.3%). A CSF-TPPA titer cutoff of ≥1:640 may be useful in identifying patients with neurosyphilis when CSF-VDRL is nonreactive.

The rapid plasma reagin test cannot replace the venereal disease research laboratory test for neurosyphilis diagnosis.

BACKGROUND: The cerebrospinal fluid (CSF) Venereal Disease Research Laboratory (VDRL) test is a mainstay for neurosyphilis diagnosis, but it lacks diagnostic sensitivity and is logistically complicated. The rapid plasma reagin (RPR) test is easier to perform, but its appropriateness for use on CSF is controversial. METHODS: RPR reactivity was determined for CSF from 149 individuals with syphilis using 2 methods. The CSF-RPR was performed according to the method for serum. The CSF-RPR-V was performed using the method recommended for the CSF-VDRL. Laboratory-defined neurosyphilis included reactive CSF-fluorescent treponemal antibody absorption test and CSF white blood cells >20/uL. Symptomatic neurosyphilis was defined as vision loss or hearing loss. RESULTS: CSF-VDRL was reactive in 45 (30.2%) patients. Of these, 29 (64.4%) were CSF-RPR reactive and 37 (82.2%) were CSF-RPR-V reactive. There were no instances where the CSF-VDRL was nonreactive but the CSF-RPR or CSF-RPR-V was reactive. Among the 28 samples that were reactive in all 3 tests, CSF-VDRL titers (median [IQR], 1:4 [1:4-1:16]) were significantly higher than CSF-RPR (1:2 [1:1-1:4], P = 0.0002) and CSF-RPR-V titers (1:4 [1:2-1:8], P = 0.01). The CSF RPR and the CSF-RPR-V tests had lower sensitivities than the CSF-VDRL: 56.4% and 59.0% versus 71.8% for laboratory-diagnosed neurosyphilis and 51.5% and 57.6% versus 66.7% for symptomatic neurosyphilis. CONCLUSIONS: Compared with the CSF-VDRL, the CSF-RPR has a high false-negative rate, thus not improving upon this known limitation of the CSF-VDRL for neurosyphilis diagnosis. Adapting the RPR procedure to mimic the CSF-VDRL decreased, but did not eliminate, the number of false negatives and did not avoid all the logistical complications of the CSF-VDRL.

CXCL13 as a cerebrospinal fluid marker for neurosyphilis in HIV-infected patients with syphilis.

BACKGROUND: Asymptomatic neurosyphilis is more difficult to diagnose in human immunodeficiency virus (HIV)-infected patients because HIV itself can cause cerebrospinal fluid (CSF) pleocytosis. The proportion of CSF lymphocytes that are B cells is elevated in neurosyphilis, suggesting that the CSF concentration of the B cell chemoattractant, chemokine (C-X-C motif) ligand 13 (CXCL13) concentration may also be elevated. METHODS: CSF and blood were collected from 199 HIV-infected patients with syphilis and neurosyphilis. Serum and CSF CXCL13 concentrations were determined. RESULTS: Patients with neurosyphilis had higher CSF and serum CXCL13 concentrations compared to patients with syphilis but not neurosyphilis. The odds of having symptomatic neurosyphilis were increased by 2.23-fold for every log increase in CSF CXCL13 concentration and were independent of CSF white blood cell and plasma HIV RNA concentrations, peripheral blood CD4+ T cell count and use of antiretroviral medications. A cut-off of 10 pg/mL CSF CXCL13 had high sensitivity and a cut-off of 250 pg/mL or evidence of intrathecal synthesis of CXCL13 had high specificity for diagnosis of both symptomatic and asymptomatic neurosyphilis. CSF concentrations of CXCL13 declined after treatment for neurosyphilis. CONCLUSIONS: CSF CXCL13 concentration may be particularly useful for diagnosis of neurosyphilis in HIV-infected patients because it is independent of CSF pleocytosis and markers of HIV disease.

Normalization of serum rapid plasma reagin titer predicts normalization of cerebrospinal fluid and clinical abnormalities after treatment of neurosyphilis.

BACKGROUND: Success of neurosyphilis treatment is defined by normalization of cerebrospinal fluid (CSF) and clinical abnormalities. The goal of this study was to determine whether normalization of serum rapid plasma reagin (RPR) titer could accurately predict treatment success. METHODS: One hundred ten patients who were enrolled in a longitudinal study of CSF abnormalities in syphilis had asymptomatic syphilitic meningitis, symptomatic syphilitic meningitis, or syphilitic eye disease and were treated for neurosyphilis. At 4, 7, and 13 months after treatment, serum RPR titer and CSF and clinical abnormalities were analyzed for normalization. Odds ratios for normalization of each CSF and clinical abnormality when serum RPR titer had normalized and the positive predictive value of normalization of serum RPR titer for normalization of CSF and clinical abnormalities were determined. RESULTS: Serum RPR titer had normalized in 63 patients (57%) by 4 months after treatment, in 94 (85%) by 7 months, and in 97 (88%) by 13 months. Except for CSF protein concentration, normalization of serum RPR titer predicted normalization of other CSF and clinical abnormalities in >80% of patients at 4 months, >85% at 7 months, and >90% at 13 months. The odds of normalization of CSF and clinical abnormalities were 28-57-fold higher when serum RPR titer had normalized, compared with when it had not. Normalization of serum RPR titer was consistently less accurate in predicting treatment success in human immunodeficiency virus-infected patients who were not receiving antiretroviral therapy, compared with those who were receiving such therapy. CONCLUSIONS: In most instances, normalization of serum RPR titer correctly predicts success of treatment of neurosyphilis, and follow-up lumbar puncture can be avoided.
