    Abstract Introduction: Home-based self-collected dried blood spot (DBS) sampling could simplify sexual health and preexposure prophylaxis care and reduce sexually transmitted infections (STIs) clinic visits for men who have sex with men (MSM). We compared the performance of DBS to venipuncture collected blood samples to test four STIs and creatinine concentration.
    Methods: We invited MSM clients of the Amsterdam STI clinic to participate. Routinely collected peripheral blood was tested for syphilis treponemal antibody, HIV (HIV Ag/Ab), HCV (antibodies), HBV (HBsAg) and creatinine concentration. Participants received a home kit for DBS sampling, a return envelope and a questionnaire to evaluate the acceptability, feasibility and usability of DBS, measured on 5-point Likert scales, 1 representing complete disagreement and 5 complete agreement. We assessed sensitivity and specificity of DBS versus peripheral blood-based testing.
    Results: In 2020 to 2021, we included 410 participants; 211 (51.5%) returned a completed DBS card, 117 (28.5%) returned a partially filled card and 82 (20.0%) did not return a card. The sensitivity for syphilis was 90.8% and the specificity 84.3%. For both HIV Ag/Ab and HBsAg, the sensitivity and specificity were 100.0%. The sensitivity for HCV antibody was 80.0%, and the specificity was 99.2%. The DBS creatinine concentration was a mean of 5.3 μmol/L higher than in venipuncture obtained plasma. Participants' median willingness to take a future DBS was 4 (interquartile range, 3-5).
    Discussion: Dried blood spot may be an acceptable method among MSM for STI testing and creatinine follow-up during preexposure prophylaxis use. However, collecting enough blood on DBS cards was a challenge, and sensitivities for syphilis and HCV serology were too low.

    Abstract This retrospective case-control study assesses the sensitivity, specificity, and area under the curve of the ZEUS Borrelia VlsE1/pepC10 assay in comparison with the C6-ELISA in European patients with Lyme borreliosis, healthy blood donors, and potentially cross-reactive controls. We included a convenience series of 161 sera from patients with physician-confirmed early localized or disseminated Lyme borreliosis (n = 143), 400 sera from healthy blood donors and 44 sera with potentially cross-reactive antibodies, on which we performed the aforementioned serological assays and the recomLine immunoblot. Diagnostic parameters were compared in various single-tier and two-tier algorithms. The specificities of the C6-ELISA and the ZEUS Borrelia VlsE1/pepC10 were comparable in healthy blood donors (e.g., single-tier permissive: C6: 362/400, 90.5% [87.2-93.2]; VlsE1/pepC10: 361/400, 90.3% [86.9-93.0]). The C6-ELISA had an apparently higher sensitivity in EM sera (e.g., both time points combined: C6: 61/76, 80.3% [69.5-88.5]; VlsE1/pepC10: 54/76, 71.1% [59.5-80.9]), but these differences were all not-significant. Interestingly, the VlsE1/pepC10 assay had a significantly higher specificity in sera with potentially cross-reactive antibodies (e.g., single-tier permissive: C6: 34/44, 77.3% [62.2-88.5]; VlsE1/pepC10: 40/44, 90.9% [78.3-97.5]; p = 0.031). While the areas under the curve for both assays were excellent, that of the C6-ELISA exceeded that of the VlsE1/pepC10 (C6: AUC = 0.925; VlsE1/pepC10: AUC = 0.878; p = 0.003). The novel ZEUS Borrelia VlsE1/pepC10 assay has generally comparable diagnostic parameters to the C6-ELISA with potentially improved specificity in cross-reactive sera. Thus, it is a useful tool for the serodiagnosis of Lyme borreliosis in Europe.

    Abstract Background: Syphilis diagnosis may be challenging, especially in the asymptomatic and early clinical stages. We evaluated the presence of Treponema pallidum DNA (TP-DNA) in various sample types to elucidate transmissibility during various syphilis stages.
    Methods: The study was conducted at the Amsterdam Centre for Sexual Health. We included adult men who have sex with men (MSM), who were suspected of having syphilis. The 2020 European guidelines definitions were followed for the diagnosis and staging of syphilis. Using a polymerase chain reaction (PCR) targeting the polA gene of Treponema pallidum (TP-PCR), we tested the following study samples on TP-DNA: peripheral blood, oropharyngeal swab, ano-rectal swab, and urine.
    Results: From November 2018 to December 2019 we included 293 MSM. Seventy clients had primary syphilis, 73 secondary syphilis, 86 early latent syphilis, 14 late latent syphilis, 23 treated syphilis, and 27 had no syphilis. TP-DNA was detected in at least 1 study sample in 35/70 clients with primary syphilis (2/70 peripheral blood, 7/70 oropharynx, 13/70 ano-rectum, and 24/70 urine); in 62/73 clients with secondary syphilis (15/73 peripheral blood, 47/73 oropharynx, 37/73 ano-rectum, and 26/73 urine); and in 29/86 clients with early latent syphilis (5/86 peripheral blood, 21/86 oropharynx, 11/86 ano-rectum, and 6/86 urine). TP-DNA was not detected in clients with late latent syphilis or treated syphilis, nor in clients without syphilis.
    Conclusions: TP-DNA was frequently detected in various sample types in the absence of lesions. This is in line with the high transmission rate of syphilis and opens diagnostic opportunities for early presymptomatic syphilis stages.

    Abstract Modified two-tier testing (MTTT) for Lyme borreliosis (i.e. confirmation with an EIA instead of an immunoblot) has been shown to have improved sensitivity compared with standard two-tier testing (STTT) in samples from American patients, without losing specificity. The current study assesses the sensitivity and specificity of various algorithms of MTTT in European patients with erythema migrans (EM) as a model disease for early Lyme borreliosis, and in appropriate controls. Four different immunoassays were used in the first tier, followed by either an immunoblot or the C6-EIA, or were used as standalone single-tier test. These tests were performed on consecutively collected sera of 228 Dutch patients with physician-diagnosed EM in the setting of general practice, 231 controls from the general population, and 50 controls with potentially cross-reactive antibodies. All the variants of MTTT that were studied had significantly higher sensitivity compared with their equivalent STTT, while retaining comparable specificity. Within the MTTT algorithms, classifying equivocal results as positive yielded better diagnostic parameters than classifying equivocal results as negative. The best diagnostic parameters were found using the Enzygnost-2 assay in the first tier, followed by a C6-ELISA in the second tier (sensitivity 77.6%, 95% CI 71.7-82.9; specificity 96.1%, 95% CI 92.7-98.2). This algorithm performed significantly better than the equivalent STTT algorithm in terms of sensitivity (p < 0.001), while maintaining comparable specificity (population controls p = 0.617). Our results show that MTTT can be a useful tool for the serodiagnosis of European patients with early Lyme borreliosis.

    Abstract The purpose of this study was to compare guideline recommendations and day-to-day practice of serological testing for Lyme borreliosis (LB) in a laboratory located in Amsterdam, the Netherlands, serving both regional hospitals and primary care physicians. By telephone interview, we obtained clinical information regarding 488 requests for LB serology. Screening for LB was performed with a C6-peptide EIA and confirmed by recombinant immunoblot. A total of 82 % of the requests were not supported by guideline's recommendations and either originated from patients with atypical symptoms and a low a priori chance for LB or from patients for which testing on LB was not recommended for other reasons. C6-EIA screening was positive in 5 % of patients with atypical symptoms, comparable to the seroprevalence in the Dutch population. Interestingly, 10 % of the requests were from patients with atypical skin lesions, of which 20 % was positive, suggesting that serological testing is of additional value in a selection of such patients. Strikingly, only 9 % of the requests were supported by recommendations by guidelines. The percentage of positive confirmatory IgM and/or IgG immunoblots did not differ substantially between the groups and ranged from 56 to 75 %. Guidelines for testing for LB are not adequately followed in the Netherlands. Better education and adherence to the guidelines by physicians could prevent unnecessary diagnostics and antibiotic treatment of supposed LB patients.

    Abstract A retrospective nationwide survey on the occurrence of Capnocytophaga canimorsus and Capnocytopaga cynodegmi infections in The Netherlands over 3 years showed 32 cases, of which 31 were caused by C. canimorsus and one by an unspecified oxidase-positive Capnocytophaga strain. Twenty-eight patients had been diagnosed by blood culture, one by culture from both blood and cerebrospinal fluid (CSF), one by culture from a conjunctival swab, and two patients by 16S rRNA gene amplification by PCR directly from a blood or CSF specimen. The incidence rate was 0.67 infections per million population. Bacteraemia was found in 94% of the cases. The age range of patients was 38-80 years; 72% of them were male. Among 26 patients from whom clinical data were available, splenectomy was not reported, but alcoholism was reported in five. Nine patients (35%) had been admitted to the intensive-care unit, and three patients (13%) died. The mortality rate was much lower than observed in previous studies.

    Abstract Background: Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) is associated with an increased risk of infection. Colonization with MRSA is observed in < 1% of the general Dutch population. Increased risk for MRSA carriage is known to occur in several key groups, one of which is asylum seekers. However, little is known about MRSA carriage among undocumented migrants and uninsured legal residents. This study aimed to determine the prevalence of nasal MRSA carriage among these groups in Amsterdam, the Netherlands.
    Methods: In this cross-sectional study, between October 2018 and October 2019, undocumented migrants and uninsured legal residents aged 18 years or older who were able to understand one of the study languages were recruited at an NGO health care facility in Amsterdam, the Netherlands, for general practitioner (GP) consultations. Participants were asked questions on demographics, migration history, antibiotic use and other possible risk factors for MRSA carriage and were screened for nasal MRSA carriage by selective culturing e-swabs. Characteristics of MRSA-negative and MRSA-positive participants were compared using univariable logistic regression analysis with Firth's correction.
    Results: Of the 3822 eligible patients, 760 were screened for nasal MRSA carriage (19.9%). Of the 760 participants, over half were male (58%; 442/760) and originated mainly from Africa (35%; 267/760), Asia (30%; 229/760) and North or South America (30%; 227/760). In total, 705/760 participants (93%) were undocumented migrants and 55/760 (7%) were uninsured legal residents of Amsterdam. The overall prevalence of nasal MRSA carriage was 2.0% (15/760) (95%CI 1.1 to 3.2%), with no difference between undocumented migrants (14/705) (2.0, 95%CI 1.1 to 3.3%) and uninsured legal residents (1/55) (1.8, 95%CI 0.1 to 9.7%). Genotyping showed no clustering of the 15 isolates. MRSA carriage was not associated with sociodemographic, migration history or other possible risk factors. Nevertheless, this study had limited power to detect significant determinants. Three participants (3/15; 20%) harbored Panton-Valentine leukocidin (PVL)-positive isolates.
    Conclusion: Even though our study population of undocumented migrants and uninsured legal residents had a higher prevalence of nasal MRSA carriage compared to the general Dutch population, the prevalence was relatively low compared to acknowledged other high-risk groups.
