Abstract Background The diagnosis of neurosyphilis is challenging due to the requirement of a lumbar puncture and cerebrospinal fluid (CSF) laboratory tests. Therefore, a convenient diagnostic nomogram for neurosyphilis is warranted. This study aimed to construct diagnostic models for diagnosing neurosyphilis. Methods This cross-sectional study included data of two patient cohorts from Western China Hospital of Sichuan University between September 2015 and April 2021 and Shangjin Hospital between September 2019 and April 2021 as the development cohort and the external validation cohort, respectively. A diagnostic model using logistic regression analysis was constructed to readily provide the probability of diagnosis at point of care and presented as a nomogram. The clinical usefulness of the diagnostic models was assessed using a receiver operating characteristic (ROC) and Harrell concordance (Harrell C) index for discrimination and calibration plots for accuracy, which adopted bootstrap resampling 500 times. Results One hundred forty-eight and 67 patients were included in the development and validation cohorts, respectively. Of those, 131 were diagnosed as having reactive neurosyphilis under the criteria of positive results in both CSF treponemal and non-treponemal tests. In the development cohort, male, psychiatric behaviour disorders, and serum toluidine red unheated serum test were selected as diagnostic indicators applying a stepwise procedure in multivariable logistic model. The model reached 80% specificity, 79% sensitivity, and 0·85 area under the curves (AUC) (95% confidence interval, 0·76–0·91). In the validation cohorts, the Harrell C index for the diagnostic possibility of reactive neurosyphilis was 0·71. Conclusions A convenient model using gender, presence of psychiatric behaviour disorders, and serum TRUST titre was developed and validated to indicate diagnostic results in patients suspected of neurosyphilis. Checking the model value of factors on nomogram is a feasible way to assist clinicians and primary health servers in updating patients’ medical charts and making a quantitatively informed decision on neurosyphilis diagnosis. Trial registration This research was retrospectively registered in the Ethics committee on biomedical research, West China Hospital of Sichuan University. The research registration and committee’s reference number was 1163 in 2020 approval.

Abstract Background: The diagnosis of neurosyphilis (NS) is challenging due to the requirement of a lumbar puncture and cerebrospinal fluid (CSF) tests. Methods: This cross-sectional study constructed diagnostic models for diagnosing NS with data gathered from the Western China Hospital of Sichuan University between September 2015 and April 2021 and Shangjin hospital between September 2019 and April 2021, which formed the development and validation cohorts, respectively. A logistic analysis was performed to predict reactive neurosyphilis diagnosis and was presented as a nomogram. Clinical usefulness of the diagnostic models was assessed using a receiver operating characteristic (ROC) curve analysis, and Harrell C index was used for discrimination and calibration plots for accuracy, adopting bootstrap resampling 500 times. Results: Overall, 149 and 67 patients were included in development and validation cohorts, respectively. Of those, 131 were diagnosed as having reactive NS with positive results in CSF treponemal and non-treponemal tests. In the development cohort, male sex, psychiatric symptoms, and serum toluidine red unheated serum test were selected as diagnostic indicators. The model reached 80% specificity, 79% sensitivity, and 0·85 area under the curves (AUC) (95% CI, 0·76-0·91). In the validation cohorts, the Harrell C index for the diagnostic possibility of reactive NS was 0·71. Conclusion: A convenient model using gender, presence of psychiatric symptoms and serum TRUST titre was developed and validated to indicate diagnostic results in patients suspected of NS. Checking model value of factors on nomogram is a feasible way to assist clinicians and primary health servers in updating patients’ medical chart and making quantitatively informed decision on NS diagnosis.
