ABSTRACT

Does anal HPV viral load explain the difference in anal HPV persistence between HIV-negative and -positive men who have sex with men (MSM)? MSM ≥18 years were recruited in Amsterdam, the Netherlands, in 2010-2011. Anal self-swabs were collected every 6 months and genotyped (SPF10 -PCR-DEIA-LIPA25 -system). HPV16 and HPV18 load was determined with a type specific quantitative (q)PCR, and compared between HIV-negative and -positive men using ranksum test. Persistence was defined as ≥3 positive samples for the same HPV-type. Determinants of persistent HPV16/18 infection and its association with HPV16/18 load were assessed with logistic regression. Of 777 recruited MSM, 54 and 22 HIV negative men were HPV16 and HPV18 positive at baseline, and 64 and 39 HIV-positive MSM. The geometric mean titer (GMT) of HPV16 was 19.6 (95%CI 10.1-38.0) and of HPV18 8.6 (95%CI 2.7-27.5) DNA copies/human cell. HPV16 and HPV18 load did not differ significantly between HIV-negative and -positive MSM (P = 0.7; P = 0.8, respectively). In multivariable analyses HPV16 load was an independent determinant of HPV16 persistence (OR 1.8, 95%CI 1.3-2.4). No difference in anal HPV viral load was found between HIV-positive and HIV-negative MSM. HPV 16/18 viral load is an independent determinant of type-specific persistence.

ABSTRACT

Background: Direct-acting antivirals (DAAa) cure hepatitis C virus (HCV) infections in 95% of infected patients. Modeling studies predict that universal HCV treatment will lead to a decrease in the incidence of new infections but real-life data are lacking. The incidence of HCV among Dutch human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) has been high for >10 years. In 2015 DAAs became available to all Dutch HCV patients and resulted in a rapid treatment uptake in HIV-positive MSM. We assessed whether this uptake was followed by a decrease in the incidence of HCV infections. Methods: Two prospective studies of treatment for acute HCV infection enrolled patients in 17 Dutch HIV centers, having 76% of the total HIV-positive MSM population in care in the Netherlands. Patients were recruited in 2014 and 2016, the years before and after unrestricted DAA availability. We compared the HCV incidence in both years. Results: The incidence of acute HCV infection decreased from 93 infections during 8290 person-years of follow-up (PYFU) in 2014 (11.2/1000 PYFU; 95% confidence interval [CI], 9.1-13.7) to 49 during 8961 PYFU in 2016 (5.5/1000 PYFU; 4.1-7.2). The incidence rate ratio of 2016 compared with 2014 was 0.49 (95% CI, .35-.69). Simultaneously, a significant increase in the percentage positive syphilis (+2.2%) and gonorrhea (+2.8%) tests in HIV-positive MSM was observed at sexual health clinics across the Netherlands and contradicts a decrease in risk behavior as an alternative explanation. Conclusions: Unrestricted DAA availability in the Netherlands was followed by a 51% decrease in acute HCV infections among HIV-positive MSM.

ABSTRACT

OBJECTIVES: Our aim was to assess incidence and persistence of oral HPV infection in HIV-negative and HIV-infected men who have sex with men (MSM). METHODS: MSM aged ≥18 years were included in Amsterdam (the Netherlands) in 2010-2011, and followed up 6 months later. Participants completed risk factor questionnaires. HPV DNA was analyzed in oral-rinse and gargle specimens using the SPF10-PCR DEIA/LiPA25 system (version 1). A subset of oral samples was subjected to SPF10 sequencing to identify additional HPV types. Multivariable logistic regression analyses using generalized estimating equations (GEE) were performed to assess determinants for oral high-risk HPV incidence and persistence. RESULTS: 689/795 participant MSM provided both baseline and 6-month data. Baseline prevalence of high-risk HPV was 9.4% in HIV-negative and 23.9% in HIV-infected MSM (P<0.001). 56/689 MSM acquired ≥1 high-risk HPV infection (6-month incidence 8.1%; 95%CI 6.2-10.4%); incidence was 4.1% in HIV-negative and 14.1% in HIV-infected MSM (P<0.001). HIV infection and recent use of cannabis were both independently associated with high-risk HPV incidence. Persistent high-risk HPV was observed in 48/130 (36.9%) infections. CONCLUSION: Incidence of oral high-risk HPV infection in MSM is substantial, and is associated with HIV infection. Over a third of HPV infections persisted over a 6-month period.

ABSTRACT

BACKGROUND: Our aim was to compare the 12-month incidence and clearance of oral high-risk HPV infection between HIV-infected men who have sex with men (MSM) and HIV-negative MSM. METHODS: MSM aged 18 years or older were recruited in Amsterdam, the Netherlands. Questionnaire data and oral-rinse and gargle samples were collected at baseline, and after 6 and 12 months. HPV DNA was genotyped using the SPF10-PCR & DEIA-LiPA25 system (version 1). Determinants of oral HPV incidence and clearance were explored using Cox and logistic regression analyses respectively. RESULTS: 433 HIV-negative and 290 HIV-infected MSM were included in these analyses. The median follow-up time per participant was 12 months (range 3-15). During follow-up, 114 incident oral high-risk HPV infections were observed. The incidence rate of HPV-16 was 3.5/1000 person-months (PM) in HIV-infected and 0.9/1000 PM in HIV-negative MSM (IRR 4.1; 95% CI 1.3-13.2). The incidence rates of other high-risk HPV types ranged between 1.3-3.5/1000 PM in HIV-infected and 0.0-1.1/1000 PM in HIV-negative MSM. In multivariable analyses, HIV infection (adjusted hazard ratio [aHR] 3.8; 95% CI 2.3-6.2) and a higher number of recent oral sex partners (aHR 2.4 for ≥8 partners compared to ≤2; 95% CI 1.4-4.2) were associated with HPV incidence. Of the 111 baseline oral high-risk infections, 59 (53.2%) were cleared. In multivariable analyses, only a higher number of recent oral sex partners was associated with HPV clearance (adjusted odds ratio 3.4 for ≥8 compared to ≤2 partners; 95% CI 1.3-9.0). CONCLUSIONS: The incidence rate of oral high-risk HPV infection was higher in HIV-infected MSM and in those with a higher number of recent oral sex partners. Just over half of the oral high-risk HPV infections at baseline were cleared after 12 months, with a higher likelihood of clearance among MSM reporting higher numbers of recent oral sex partners, but no difference by HIV status.

ABSTRACT

OBJECTIVE: Anal and penile high-risk human papillomavirus (HPV) infection is associated with anogenital cancer, which is especially common in HIV-infected MSM. We assessed HPV prevalence and determinants in MSM. DESIGN: Analysis of baseline data from a prospective cohort study. METHODS: MSM aged 18 years or older were recruited in Amsterdam, the Netherlands. Participants completed risk-factor questionnaires. HPV DNA was analyzed in anal and penile shaft self-swabs and genotyped using a sensitive PCR and reverse line blot assay (SPF10-PCR-DEIA-LiPA25-system). Multivariable logistic regression analyses were performed to assess determinants of high-risk HPV infection. RESULTS: MSM (n = 778) were recruited in 2010-2011, of whom 317 (41%) were HIV-infected. Prevalence of anal high-risk HPV infection was 45% in HIV-negative versus 65% in HIV-infected MSM (P <0.001). HPV-16 was the most frequently detected type and was more common in HIV-infected MSM (13% in HIV-negative and 22% in HIV-infected MSM; P = 0.001). Prevalence of penile high-risk HPV infection was 16% in HIV-negative and 32% in HIV-infected MSM (P <0.001). In multivariable analyses, HIV infection remained associated with anal [adjusted odds ratio (aOR) 2.2; 1.8-2.7] and penile (aOR 2.0; 1.4-2.9) high-risk HPV infection. Higher number of lifetime male sex partners was significantly associated with anal and penile high-risk HPV in HIV-negative, but not HIV-infected MSM. Receptive anal intercourse was associated with anal high-risk HPV in HIV-infected MSM. CONCLUSION: Anal and penile high-risk HPV infections are very common in MSM. HIV infection is a strong and independent determinant for anal and penile high-risk HPV infection. Determinants for HPV infection appear to differ between HIV-negative and HIV-infected MSM.

ABSTRACT

OBJECTIVE: Oral infection with human papillomavirus (HPV) is associated with a subset of head and neck cancers. We compared prevalence of, and risk factors for, oral HPV infection among HIV-negative and HIV-infected MSM. DESIGN: Analysis of baseline data from a prospective cohort study. METHODS: MSM aged 18 years or older were recruited from three study sites in Amsterdam, the Netherlands. Participants completed a self-administered risk-factor questionnaire. Oral-rinse and gargle specimens were analyzed for HPV DNA and genotyped using a highly sensitive PCR and reverse line blot assay [short PCR fragment (SPF)10-PCR-DNA Enzyme Immuno Assay (DEIA)/LiPA25 system]. RESULTS: In 2010-2011, 794 MSM were included, of whom 767 participants had sufficient data for analysis. Median age was 40.1 years [interquartile range (IQR) 34.8-47.5] and 314 men were HIV-infected (40.9%). Any of 25 typable HPV types was present in 24.4% of all oral samples. Oncogenic HPV types were detected in 24.8 and 8.8% of oral samples from HIV-infected and HIV-negative MSM, respectively (P < 0.001). Of these high-risk types, HPV-16 was the most common (overall 3.4%). Oral infection with high-risk HPV was associated with HIV infection in multivariable analysis (P < 0.001). Increasing age was significantly associated with oral HPV infection in HIV-negative, but not in HIV-infected MSM. CONCLUSION: Oral HPV infection is very common among MSM. HIV infection was independently associated with high-risk oral HPV infection, suggesting an important role of HIV in oral HPV infection.

ABSTRACT

BACKGROUND: The long-term prognosis of endocarditis is described primarily in relation to clinical outcome measures-for example, such complications as cerebrovascular accident, cardiac failure, need for cardiac surgery, relapse rate, and mortality. To our knowledge, to date, no studies have examined the health-related quality of life and the prevalence of long-term persistence of physical symptoms for survivors of left-sided native valve endocarditis. METHODS: We conducted a prospective follow-up study of patients treated for left-sided native valve endocarditis from 1 November 2000 through 31 October 2003 in 23 hospitals in the Netherlands. Of 86 patients eligible to participate, 55 completed questionnaires administered 3 m and 12 m after discharge; an additional 12 patients completed questionnaires 12 m after discharge only, making a total of 67 patients in our study. Persistence of symptoms and employment status were recorded. The health-related quality of life was measured by using the Dutch version of the Medical Outcomes Study Short Form 36-item health survey and the Posttraumatic Stress Disorder questionnaire. RESULTS: Three months after the end of antimicrobial treatment, 41 (75%) of 55 patients still had physical symptoms. Twelve months after the end of antimicrobial treatment, 36 (54%) of 67 patients still had physical symptoms. Before the episode of endocarditis, 30 (81%) of 37 patients aged < or =60 years were employed and working. At 3 m follow-up, 16 (52%) of 31 patients returned to work, and at 12 m follow-up, 24 (65%) of 37 patients were working. One year after discharge, the health-related quality of life was impaired in 5 of 8 dimensions, compared with age-adjusted standard values, and 7 (11%) of 64 patients suffered from posttraumatic stress disorder. CONCLUSIONS: A year after discharge, most survivors of left-sided native valve endocarditis still had persisting symptoms and a seriously diminished quality of life, and 11% of patients suffered from posttraumatic stress disorder.

ABSTRACT

BACKGROUND: The clinical course of left-sided native valve infective endocarditis varies from uncomplicated disease to fulminant infection. Although several factors are known to affect clinical outcome, it is difficult to predict morbidity and mortality in individual patients. The objective of this study was to determine the value of serial C-reactive protein (CRP) measurements as a predictor of clinical outcome. METHODS: One hundred twenty-three consecutive patients who fulfilled the Duke criteria for definite left-sided native valve infective endocarditis were prospectively enrolled. Poor outcome was defined as serious infectious complications or death. Patients were followed up for 12 weeks after the end of antimicrobial therapy. Multivariate analysis was used to examine the relative importance of the CRP level as a predictor of poor outcome after adjusting for age, abscess, multivalvular involvement, and Staphylococcus aureus infection. RESULTS: After 1 week of therapy, the adjusted odds ratio for poor outcome was 10.3 (95% confidence interval, 2.2-49.4) for patients with CRP levels in the highest tertile (>122 mg/L [to convert to nanomoles per liter, multiply by 9.524]) vs the lowest tertile (1-69 mg/L). A low percentage decline during the first week of treatment was statistically significantly associated with a higher risk of poor outcome (logistic regression coefficient, 1.1; P = .009). At no point in time did CRP level predict the need for cardiac surgery. CONCLUSION: High CRP level after 1 week of treatment and a slow percentage decline in CRP level during the first week of treatment are indicators of poor clinical outcome.

ABSTRACT

The clinical presentation of patients with Staphylococcus aureus bacteraemia (SAB) varies from uncomplicated bacteraemia to a fulminant or deep-seated infection. To assess the clinical presentation and outcome and to detect possible flaws in management of these patients, a retrospective study was conducted including 75 adult patients with SAB admitted to a university hospital in The Netherlands between July 1999 and December 2000. In 26 of the 75 (35%) patients, SAB was complicated by a deep-seated infection. In 2 patients the diagnosis of infective endocarditis was missed. The overall mortality rate was 23%. In 10 (13%) patients death could be directly ascribed to SAB. In 3 of these 10 patients antimicrobial treatment had been inadequate. Relapse of infection occurred in 9 (12%) patients. Seven of these 9 patients were treated inadequately during the first infectious period. Two of the 9 patients died and another 2 suffered serious complications during relapse of infection. These findings stress the need for consultation of infectious disease specialists in management of patients with SAB and the urgent need for standardization and a guideline considering the approach of a patient with SAB. A proposal for such a guideline is presented in this manuscript.
