ABSTRACT

Background: Confirming the efficacy of dolutegravir/lamivudine in clinical practice solidifies recommendations on its use. Methods: Prospective cohort study (DUALING) in 24 human immunodeficiency virus (HIV) treatment centers in the Netherlands. HIV RNA-suppressed cases were on triple-drug antiretroviral regimens without prior virological failure or resistance and started dolutegravir/lamivudine. Cases were 1:2 matched to controls on triple-drug antiretroviral regimens by the use of dolutegravir-based regimens, age, sex, transmission route, CD4+ T-cell nadir, and HIV RNA zenith. The primary endpoint was the treatment failure rate in cases versus controls at 1 year by intention-to-treat and on-treatment analyses with 5% noninferiority margin. Results: The 2040 participants were 680 cases and 1380 controls. Treatment failure in the 390 dolutegravir-based cases versus controls occurred in 8.72% and 12.50% (difference: -3.78% [95% confidence interval {CI}, -7.49% to .08%]) by intention-to-treat and 1.39% and 0.80% (difference: 0.59% [95% CI, -.80% to 1.98%]) by on-treatment analyses. The treatment failure risk in 290 non-dolutegravir-based cases was also noninferior to controls. Antiretroviral regimen modifications unrelated to virological failure explained the higher treatment failure rate by intention-to-treat. A shorter time on triple-drug antiretroviral therapy and being of non-Western origin was associated with treatment failure. Treatment failure, defined as 2 consecutive HIV RNA >50 copies/mL, occurred in 4 cases and 5 controls but without genotypic resistance detected. Viral blips occured comparable in cases and controls but cases gained more weight, especially when tenofovir-based regimens were discontinued. Conclusions: In routine care, dolutegravir/lamivudine was noninferior to continuing triple-drug antiretroviral regimens after 1 year, supporting the use of dolutegravir/lamivudine in clinical practice. Clinical Trials Registration: NCT04707326.

ABSTRACT

PURPOSE: Obesity is rising among people with HIV (PLWH), sparking interest in bariatric surgery (BS) for this group. Yet, large-scale comparative research on BS outcomes in PLWH is lacking. METHODS: We performed a retrospective, matched cohort analysis in PLWH and HIV uninfected controls. Subjects were retrieved from the Dutch Audit for Treatment of Obesity (DATO) registry. Matching (1:7 ratio) included age (± 5-years), sex, body-mass index (BMI) of ± 3 kg/m2, surgery type, and associated health problems (AHPs) at baseline. The primary endpoint was total weight loss percentage (%TWL) ≥ 20% achieved at 1-year post-BS. Secondary endpoints were cumulative %TWL achieved at 2-years post-BS, a reported remission or improvement in AHPs post-BS, and surgical complications, both at 1-year post-BS. Comparisons were performed using conditional logistic regression. RESULTS: Twenty-seven PLWH and 168 controls were included. At 1-year post-BS, 89% PLWH achieved ≥ 20%TWL, compared to 94% of controls (p = 0.4). Cumulative %TWL at 2-years post-BS were 82% and 92% in PLWH and controls, respectively (p = 0.2). Improvement rates in hypertension and type 2 diabetes mellitus were 50% and 86% in PLWH, versus 87% and 87% in controls. Full remission occurred in 20% and 71% of PLHIV, versus 49% and 44% of controls, respectively. No improvement or remission was observed for dyslipidaemia in PLHIV compared to 54% improvement and 29% remission in controls. Surgical complications were 0% in PLHIV and 13% (n = 21) in controls. CONCLUSION: Efficacy and safety outcomes of BS were similar between PLWH and controls except for the lack of improvement in dyslipidaemia in PLWH.

ABSTRACT

PURPOSE: Anal cancer is increasing in HIV+ men who have sex with men (MSM). Treatment options for its precursor, high-grade anal intraepithelial neoplasia (HGAIN), are suboptimal. In this phase I to II dose-finding study, we assessed the safety and efficacy of the human papillomavirus type 16 (HPV16) synthetic long peptide vaccine (SLP-HPV-01) in HIV+ MSM with HPV16-positive HGAIN. PATIENTS AND METHODS: Four dosage schedules (1-5-10; 5-10-20; 10-20-40; and 40-40-40-40 µg) of SLP-HPV-01 were administered intradermally with a 3-week interval in 10 patients per dose level (DL). In each dose group, 5 patients also received 1 µg/kg pegylated IFNα-2b subcutaneously. Primary endpoints were safety and regression of HGAIN at 3, 6, and 12 months. RESULTS: Eighty-one of 134 screened patients (60%) had HPV16-negative HGAIN lesions, leaving 53 eligible patients. Thirteen patients were excluded, leaving 40 men. The vaccine was well tolerated. One patient developed a generalized rash. The highest dosage level induced the strongest immune responses. There was no indication for stronger reactivity in the IFNα groups. Up to 18 months of follow-up, 8/38 intention-to-treat patients had a complete clinical and histologic response and one had a partial response (in total 9/38, 23.7%). At the highest dosage level, the clinical response was 4/10 (40%). Stronger immune responses were detected among clinical responders. CONCLUSIONS: The highest DL is safe, immunogenic, and associated with clinical responses to HPV16-induced lesions. However, as the majority of HGAIN is caused by the other HPV types, further studies should aim at pan-HPV vaccination to prevent or treat HGAIN.

ABSTRACT

BACKGROUND: The implications of bariatric surgery (BS) on virologic and metabolic outcomes in people with human immunodeficiency virus (HIV; PWH) on antiretroviral therapy (ART) are unknown. METHODS: Here, we report a retrospective analysis up to 18 months post-BS in PWH from the AIDS Therapy evaluation in The Netherlands (ATHENA) cohort with data from all dutch HIV treating Centers. Primary end points were a confirmed virologic failure (2 consecutive HIV-RNA measurements >200 copies/mL) and the percentage of patients who achieved >20% total body weight loss up to 18 months post-BS. Switches from baseline ART and trough plasma concentrations of antiretrovirals were also reported post-BS. Metabolic parameters and medication usage were compared pre- and post-BS. RESULTS: Fifty-one patients were included. One case of confirmed virologic failure and 3 cases with viral blips were detected in this cohort up to 18 months post-BS. Eighty-five percent of patients achieved >20% total body weight loss at 18 months post-BS, with a mean difference from baseline (95% confidence interval) of -33.5% (-37.7% to -29.3%). Trough plasma concentrations of measured antiretroviral agents were all above minimum effective concentrations, except for 1 sample of darunavir. Lipid profiles, but not serum creatinine and blood pressure, improved significantly (P < .01) post-BS. Total medications and obesity-related comedications declined from 203 to 103 and from 62 to 25, respectively, at 18 months post-BS. CONCLUSIONS: BS was an effective intervention for weight loss and lipid control in PWH using ART in this cohort with no clear link to poor virologic outcomes.

ABSTRACT

OBJECTIVE: Lower urinary tract symptoms (LUTS) are becoming more prevalent in the ageing population of males living with HIV. Drugs to treat LUTS are known for both their potential role as victims in drug-drug interactions (DDIs) and their side effects. We aimed to evaluate the current use of drugs to treat LUTS and to assess potential DDIs in our cohort of adult males living with HIV. DESIGN: This was a retrospective review of pharmacy records. METHODS: We recorded the combination antiretroviral therapy (cART) regimen and any use of drugs to treat LUTS (anatomical therapeutic chemical codes G04CA/CB/CX and G04BD). Potential DDIs were assessed using the interaction checker developed by the University of Liverpool (https://www.hiv-druginteractions.org/checker). RESULTS: A total of 411 adult males living with HIV were included in this analysis. The median (interquartile range [IQR]) age was 53 (41-62) years. Nineteen (4.6%) patients used one or more drugs to treat LUTS. As expected, older patients were more likely to be receiving treatment for LUTS: Q1 (20-40 years) = 0%; Q2 (41-52 years) = 2%; Q3 (53-61 years) = 7%; Q4 (62-79 years) = 10%. Seven potential DDIs between cART and LUTS treatment were noted in six of the 19 (32%) patients. Following medication reviews of these six patients, the following interventions were proposed: evaluate safe use of alpha-blocker (n = 4), change in cART (n = 2), and dose reduction of the anticholinergic agent (n = 1). CONCLUSION: Treatment for LUTS coincided with cART in 7%-10% of patients aged above the median age of 53 years in our cohort. Improvements in DDI management appeared to be possible in this growing cohort of males living with HIV and with LUTS.

ABSTRACT

BACKGROUND: Incidence of anal cancer is high in people living with HIV, particularly in men who have sex with men (MSM). Screening for and treatment of precursor lesions might prevent progression to anal cancer in people living with HIV. We examined trends in incidence of and mortality after anal cancer diagnosis in people living with HIV, including the effect of screening from 2007 onwards, in the Netherlands. METHODS: In this observational cohort study, we analysed data from the ongoing open nationwide Dutch AIDS Therapy Evaluation in the Netherlands (ATHENA) cohort. We included all consenting adults living with HIV and identified all primary anal squamous cell carcinoma. We reported temporal trends in incident anal cancer cases from Jan 1, 1996, to Dec 31, 2020, and all-cause and anal cancer-related mortality in individuals diagnosed with anal cancer. Multivariable Poisson regression was used to explore risk factors for incident anal cancer and multivariable Cox regression was used to explore risk factors for anal cancer-related mortality. FINDINGS: Among 28 175 individuals in HIV care (59·7% MSM), 227 primary anal cancer cases were diagnosed. Despite the increasing average age of the cohort, crude incidence rates of anal cancer in MSM declined slowly over time, from 107·0 (95% CI 75·7-147·0) per 100 000 person-years in 1996-2005 to 93·7 (75·3-115·0) per 100 000 person-years in 2013-20 (p=0·49). Crude incidence rates in men who do not have sex with men (non-MSM) and women were generally lower than in MSM, but increased slightly over time, from 51·08 (95% CI 20·54-105·25) to 67·82 (40·83-105·91; p=0·52) per 100 000 person-years in non-MSM and from 8·09 (0·20-45·06) to 24·95 (10·03-51·40; p=0·29) per 100 000 person-years in women. The age-adjusted incidence rate in MSM in 2013-20 was significantly lower (rate ratio 0·62 [95% CI 0·41-0·92]) compared with in 1996-2005. Changes in risk factors (less smoking, cumulative exposure to CD4 count of <200 cells per µL, and plasma HIV-1 RNA of >1000 copies per mL) mostly explained the decrease in anal cancer risk over time in MSM. 3866 (23·0%) of 16 819 MSM participated in anal cancer screening at least once. TNM tumour staging was more favourable (Cochrane-Armitage test for trend p=0·033) in individuals diagnosed during screening. Crude anal cancer-associated 5-year mortality in people living with HIV decreased from 30·4% (1996-2005) to 18·3% (2013-20; odds ratio 0·48; p=0·070). Anal cancer-related mortality was 3·7% (95% CI 0·5-23·5) in all men who had been screened and 24·0% (95% CI 18·1-31·3) in men who had not been screened (p=0·023). In men, screening participation (hazard ratio [HR] 0·31, p=0·051) and cumulative exposure to CD4 counts of less than 200 cells per µL (HR 1·11 per year; p=0·0022) were independently associated with anal cancer-related mortality. INTERPRETATION: As anal cancer incidence is slowly declining in MSM but not in non-MSM and women, health-care professionals should not focus only on MSM for anal cancer prevention. Men diagnosed with anal cancer during screening had improved survival, probably because they were diagnosed at an earlier disease stage. Next to preventing anal cancer, these data are an important justification to screen those most at risk of anal cancer. FUNDING: None.

ABSTRACT

Bariatric surgery is increasingly applied among people living with HIV to reduce obesity and the associated morbidity and mortality. In people living with HIV, sufficient antiretroviral exposure and activity should always be maintained to prevent development of resistance and disease progression. However, bariatric surgery procedures bring various gastrointestinal modifications including changes in gastric volume, and acidity, gastrointestinal emptying time, enterohepatic circulation and delayed entry of bile acids. These alterations may affect many aspects of antiretroviral pharmacokinetics. Some drug characteristics may result in subtherapeutic exposure and the potential related risk of treatment failure and resistance. Antiretrovirals that require low pH, administration of fatty meals, longer intestinal exposure, and an enterohepatic recirculation for their absorption may be most impacted by bariatric surgery procedures. Additionally, some antiretrovirals can interact with the polyvalent cations in supplements or drugs inhibiting gastric acid, thereby preventing their use as these comedications are commonly prescribed post-bariatric surgery. Predicting pharmacokinetics on the basis of drug characteristics solely proved to be challenging, therefore pharmacokinetic studies remain crucial in this population. Here, we discuss general implications of bariatric surgery on antiretroviral outcomes in people living with HIV as well as drug properties that are relevant for the choice of antiretroviral treatment in this special patient population. Additionally, we summarise studies that evaluated the pharmacokinetics of antiretrovirals post-bariatric surgery. Finally, we performed a comprehensive analysis of theoretical considerations and published pharmacokinetic and pharmacodynamic data to provide recommendations on antiretrovirals for people living with HIV undergoing bariatric surgery.

ABSTRACT

BACKGROUND: Tenofovir alafenamide (TAF), a prodrug of tenofovir (TFV), is included in the majority of the recommended first-line antiretroviral regimens for patients living with human immunodeficiency virus (HIV), but there are limited data on TAF use in pregnant women. We aimed to examine the plasma pharmacokinetics of TAF and TFV in pregnant women from Europe. METHODS: Pregnant women living with HIV were included from treatment centers across Europe, and intensive pharmacokinetic sampling in the third trimester and postpartum was performed. Pharmacokinetic parameters of TAF and TFV were determined with noncompartmental analysis. The proportion of women with a TAF area under the curve (AUClast) below the target of 53.1 ng∗h/mL was determined. Clinical efficacy and safety outcome parameters were reported. RESULTS: In total, 20 pregnant women living with HIV were included. At the third trimester, geometric mean TAF AUClast and Cmax were decreased by 46% and 52%, respectively, compared with postpartum. TFV AUC0-24h, Cmax, and Ctrough decreased by 33%, 30%, and 34%, respectively. The proportion of women with a TAF AUClast < 53.1 ng∗h/mL was 6% at third trimester and 0% postpartum. One out of 20 women had a viral load > 50 copies/mL at third trimester and no mother-to-child transmission occurred. CONCLUSIONS: TAF plasma concentrations were reduced by about half in women living with HIV during third trimester of pregnancy but remained above the predefined efficacy target in the majority of the pregnant women. TFV concentrations were reduced by approximately 30% during third trimester. Despite the observed exposure decrease, high virologic efficacy was observed in this study.

ABSTRACT

BACKGROUND: High-grade anal intraepithelial neoplasia (HGAIN; AIN2-3) is highly prevalent in HIV+ men, but only a minority of these lesions progress towards cancer. Currently, cancer progression risk cannot be established; therefore, no consensus exists on whether HGAIN should be treated. This study aimed to validate previously identified host cell DNA methylation markers for detection and cancer risk stratification of HGAIN. METHODS: A large independent cross-sectional series of 345 anal cancer, AIN3, AIN2, AIN1, and normal control biopsies of HIV+ men was tested for DNA methylation of 6 genes using quantitative methylation-specific PCR. We determined accuracy for detection of AIN3 and cancer (AIN3+) by univariable and multivariable logistic regression analysis, followed by leave-one-out cross-validation. Methylation levels were assessed in a series of 10 anal cancer cases with preceding HGAIN at similar anatomic locations, and compared with the cross-sectional series. RESULTS: Methylation levels of all genes increased with increasing severity of disease (P < .05). HGAIN revealed a heterogeneous methylation pattern, with a subset resembling cancer. ZNF582 showed highest accuracy (AUC = 0.88) for AIN3+ detection, slightly improved by addition of ASCL1 and SST (AUC = 0.89), forming a marker panel. In the longitudinal series, HGAIN preceding cancer displayed high methylation levels similar to cancers. CONCLUSIONS: We validated the accuracy of 5 methylation markers for the detection of anal (pre-) cancer. High methylation levels in HGAIN were associated with progression to cancer. These markers provide a promising tool to identify HGAIN in need of treatment, preventing overtreatment of HGAIN with a low cancer progression risk.

ABSTRACT

The worldwide rapid increase in antibiotic resistance means that new therapeutic measures are urgently needed. Older antibiotics, such as colistin, fosfomycin, minocycline, mecillinam and temocillin, which had fallen from grace due to the development of more effective and less toxic drugs are now of renewed interest in the treatment of infections caused by multiresistant bacteria. Two new glycopeptides (oritavancin and dalbavancin) and a new oxazolidinone (tedizolid) are now registered for the treatment of acute skin and soft-tissue infections. In the treatment of infections caused by Gram-negative bacteria, cephalosporins are combined with beta-lactamase inhibitors which protect them from various beta-lactamases and also make them effective against extended spectrum beta-lactamase-producing bacteria. Examples of these are ceftolozane-tazobactam, ceftazidime-avibactam and meropenem-vaborbactam. Results of preclinical research on the effectiveness of new antibiotics are hopeful. There has been a great increase in investment in the development of new antimicrobials. Also, regulatory agencies have accelerated their assessment of these new - and urgently needed - drugs.

ABSTRACT

OBJECTIVE: The aim of the study was to develop recommended techniques and quality assurance metrics for the practice of Digital Anal Rectal Examination (DARE). MATERIALS AND METHODS: The International Anal Neoplasia Society undertook a literature review and, using the AGREE II technique, developed guidelines for performing DARE. RESULTS: A consensus was formed regarding the optimum conditions and characteristics of DARE. Several Quality Assurance metrics were developed. CONCLUSIONS: Digital Anal Rectal Examination is a cheap and potentially universally available technique, which has the potential to facilitate the early diagnosis of anal cancers, when they are most amenable to treatment. These guidelines provide a basis for teaching the technique and may be used as for evaluation research.

ABSTRACT

BACKGROUND: High-grade anal intraepithelial neoplasia (AIN2/3; HGAIN) is highly prevalent in human immunodeficiency virus positive (HIV+) men who have sex with men (MSM), but only a minority will eventually progress to cancer. Currently, the cancer risk cannot be established, and therefore all HGAIN is treated, resulting in overtreatment. We assessed host cell deoxyribonucleic acid (DNA) methylation markers for detecting HGAIN and anal cancer. METHODS: Tissue samples of HIV+ men with anal cancer (n = 26), AIN3 (n = 24), AIN2 (n = 42), AIN1 (n = 22) and HIV+ male controls (n = 34) were analyzed for methylation of 9 genes using quantitative methylation-specific polymerase chain reaction. Univariable and least absolute shrinkage and selection operator logistic regression, followed by leave-one-out cross-validation, were used to determine the performance for AIN3 and cancer detection. RESULTS: Methylation of all genes increased significantly with increasing severity of disease (P < 2 × 10-6). HGAIN samples revealed heterogeneous methylation patterns, with a subset resembling cancer. Four genes (ASCL1, SST, ZIC1,ZNF582) showed remarkable performance for AIN3 and anal cancer detection (area under the curve [AUC] > 0.85). ZNF582 (AUC = 0.89), detected all cancers and 54% of AIN3 at 93% specificity. Slightly better performance (AUC = 0.90) was obtained using a 5-marker panel. CONCLUSIONS: DNA methylation is associated with anal carcinogenesis. A marker panel that includes ZNF582 identifies anal cancer and HGAIN with a cancer-like methylation pattern, warrantingvalidation studies to verify its potential for screening and management of HIV+ MSM at risk for anal cancer.

ABSTRACT

PURPOSE OF REVIEW: Anal cancer is a serious health problem in HIV-positive men who have sex with men, and precursor lesions, anal intraepithelial neoplasia, are well defined. Given the similarities with cervical cancer, screening for and treatment of anal intraepithelial neoplasia might prevent anal cancer. Screening programmes should meet the Wilson and Jungner criteria. We used these criteria to evaluate the current body of evidence supporting a screening programme for anal dysplasia. RECENT FINDINGS: The natural history of anal intraepithelial neoplasia is gradually becoming more clear, and three prospective studies are now being performed to conclusively address this issue. High-resolution anoscopy stays the gold standard to diagnose anal intraepithelial neoplasia. The International Anal Neoplasia Society has recently published Practice Standards in the Detection of Anal Cancer Precursors. The main issue, however, is treatment. Although response rates are reasonable at early evaluation, the majority of patients has a recurrence. SUMMARY: At present, an anal cancer screening programme for HIV-positive men who have sex with men meets most of the Wilson and Jungner criteria. Given that high-resolution anoscopy is the gold standard for screening, important issues that need addressing are the need for a less invasive screening procedure and the cost-effectiveness of screening. The main issue is treatment. Development and evaluation of new treatment strategies are essential for an effective and sustainable screening programme.

ABSTRACT

The number of infectious disease outbreaks and the number of unique pathogens responsible have significantly increased since the 1980s. HIV-positive men who have sex with men (MSM) are a vulnerable population with regards to the introduction, spread and clinical consequences of (newly introduced) STIs. After the introduction of combination antiretroviral treatment (cART), the incidence of sexually acquired hepatitis C virus (HCV) infection and human papillomavirus (HPV)-induced anal cancers have significantly increased among HIV-positive MSM. The introduction and expansion of HCV is the result of increased sexual risk behaviour and sexually acquired mucosal trauma within large interconnected networks of HIV-positive MSM in particular. With the availability of cART, postexposure and pre-exposure prophylaxis (PEP and PrEP) and direct-acting antivirals (DAAs) for HCV, less concern for HIV and HCV might require a new approach to develop effective behavioural intervention strategies among MSM. The marked rise in HPV-induced anal cancers can be ascribed to the long-term immunologic defects in an ageing population affected by HIV. More evidence with regards to effective treatment options for anal dysplastic lesions and the usefulness of anal malignancy screening programmes is urgently needed. Most anal cancers in the future generation of HIV-positive MSM could be prevented with the inclusion of boys in addition to girls in current HPV vaccination programmes.

ABSTRACT

BACKGROUND: The impact of the treatment of precursor lesions of anal cancer (anal intraepithelial neoplasia) on health-related quality of life has not been investigated. OBJECTIVE: This study aimed to evaluate the impact of 3 treatment options for anal intraepithelial neoplasia on health-related quality of life and sexual functioning in HIV-positive men who have sex with men. DESIGN: The prospective cohort was embedded in a randomized clinical trial evaluating the optimal treatment of anal intraepithelial neoplasia. SETTING: This study was performed at the HIV outpatient clinic of the Academic Medical Center, Amsterdam, the Netherlands. PATIENTS: Included in the study were HIV-positive men who have sex with men with anal intraepithelial neoplasia. INTERVENTION: Treatment with imiquimod (n = 54), topical fluorouracil (n = 48), or electrocautery (n = 46) was given for 16 weeks. MAIN OUTCOME MEASURES: Health-related quality of life and sexual functioning were assessed before, during, and 4 weeks after treatment. Health-related quality of life was assessed using the EQ5D, sexual functioning was assessed using items derived from the International Index of Erectile Function, and the female sexual function index adapted for anal intercourse. RESULTS: One hundred forty-five patients (98%) completed at least 1 questionnaire. There was a significant different pattern of change over time in health-related quality of life among the 3 treatment groups. Patients in the imiquimod group were more likely to report pain/discomfort at week 8 than patients in the electrocautery group. Patients in the electrocautery group were more likely to report anxiety/depression and were less satisfied with their overall sex life at week 16 than patients in the imiquimod and fluorouracil groups, and patients in the electrocautery group were also more likely to report pain/discomfort and problems with usual activities at week 20 than patients in the fluorouracil group. LIMITATIONS: The follow-up method differed slightly among treatment groups. There is no standardized, validated sexual functioning questionnaire for HIV-positive men who have sex with men. CONCLUSIONS: All treatment options have a negative impact on aspects of health-related quality of life. Electrocautery has significantly more negative effects on health-related quality of life than imiquimod and fluorouracil and also has a negative effect on sexual functioning.

ABSTRACT

We surveyed trends in incidence (1995-2012) and risk factors for anal cancer in the Dutch HIV-positive population. After an initial increase with a peak incidence in 2005-2006 of 114 [95% confidence interval (CI): 74 to 169] in all HIV+ patients and 168 (95% CI: 103 to 259) in HIV+ men who have sex with men (MSM), a decline to 72 (95% CI: 43 to 113) and 100 (95% CI: 56 to 164), respectively, was seen in 2011-2012. Low nadir CD4, alcohol use, and smoking were significantly associated with anal cancer in MSM. In conclusion, anal cancer remains a serious problem in predominantly HIV+ MSM. However, it seems that incidence rates are leveling off.

ABSTRACT

We studied 3 patients with focal intra-anal tissue high-grade squamous intraepithelial lesions (HSILs). All had increased human immunodeficiency virus type 1 (HIV-1) RNA and DNA in lesions compared with that in healthy mucosa. HIV-1 RNA and HIV-1 episomal DNA were indicative of ongoing viral replication, more so in anal HSILs.

ABSTRACT

BACKGROUND: High-grade anal intraepithelial neoplasia (AIN) is present in many human immunodeficiency virus (HIV)-positive men who have sex with men. The major etiologic factor is infection with an oncogenic human papillomavirus (HPV) genotype. We investigated whether individual components of high-grade AIN are caused by single HPV types. METHODS: DNA was isolated from whole-tissue sections of 31 high-grade AIN that were recovered from 21 HIV-positive men who have sex with men. The SPF10 PCR/LiPA25 HPV genotyping system was used for DNA analysis. In whole-tissue sections with multiple HPV types, polymerase chain reaction was repeated in regions of AIN sampled by laser-capture microdissection. The results were compared with HPV types in anal swabs. RESULTS: A single HPV type was observed in 15 (48%) of 31 whole-tissue sections. In an additional 14 whole-tissue sections, 1 HPV type was found in each lesion sample evaluated by laser-capture microdissection. Consequently, in 29 of 31 biopsy specimens (94%), a single HPV type was found in each lesional component studied. Two whole-tissue sections contained collision regions, each with 2 HPV types. HPV16 was presumed to be causative in 14 of 31 biopsy specimens (45%). More than half of the anal swabs did not contain all causative HPV types. CONCLUSIONS: Individual components of high-grade AIN are caused by single HPV types (the so-called one lesion, one virus concept). HPV16 is causative in <50% of cases. Anal swabs are not useful for detecting lesion-specific HPV types.
