Anogenital Human Papillomavirus Prevalence is Unaffected by Therapeutic Tumour Necrosis Factor-alpha Inhibition

Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV in the anorectal fistula tract. A comparative study

BACKGROUND & AIMS

Perianal fistulizing Crohn's disease is the main risk factor for anal cancer in patients with inflammatory bowel disease. Whether this occurs due to a higher frequency of human papillomavirus remains unclear. The authors aimed to evaluate the prevalence of HPV and high-risk HPV in patients with perianal Crohn's disease, compared with a control group.

METHODS

The authors conducted a two-center cross-sectional study in which perianal fistulizing Crohn's disease patients were matched for age and sex with patients with anorectal fistula without Crohn's disease. Biopsy specimens were obtained from fistulous tracts during examination under anesthesia for both groups. The samples were sent for HPV detection and genotyping using the INNO-LiPA test.

RESULTS

A total of 108 subjects (54 in each group) were recruited. The perianal fistulizing Crohn's disease group showed a statistically higher frequency of HPV in the fistulous tract than the control group (33.3% vs. 16.7%; p = 0.046). Separate analyses on high-risk types demonstrated that there was a numerically higher frequency of HPV in the perianal fistulizing Crohn's disease group. In multiple logistic regression, patients with perianal fistulizing Crohn's disease were found to have a chance of HPV 3.29 times higher than patients without Crohn's disease (OR = 3.29; 95% CI 1.20‒9.01), regardless of other variables. The types most frequently identified in the perianal fistulizing Crohn's disease group were HPV 11 (12.96%) and HPV 16 (9.26%).

CONCLUSION

Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV than in patients with anorectal fistula without Crohn's disease.

Prevalence of genital and oral HPV infection among psoriasis patients on biologic therapy

Current knowledge about human papillomavirus (HPV) infection in psoriasis patients treated with biologics is limited. In this study we evaluated the prevalence of oral and genital HPV infection in psoriasis patients treated with biologics or topical therapy for at least 6 months. The presence of HPV DNA in oral rinse and genital smears was evaluated. In total, 267 patients who met the inclusion criteria and agreed to participate were enrolled: 110 (41.2%) on topical therapy, 84 (31.5%) on anti-TNF-alpha therapy, 31 (11.6%) on anti-IL-12/23 therapy and 42 (15.7%) on anti-IL-17 therapy. The presence of genital HPV infection was detected in 34.6% of men receiving anti-TNF-α treatment, in 25.0% of patients on anti-IL-12/23 and 18.8% of patients on anti-IL-17 therapy. The difference in prevalence was not statistically different from men on topical treatment (26.3%). Prevalence of oral HPV infection was higher across all of the biologic groups (11.9% for anti-TNF-α, 12.9% for anti-IL-12/23 and 19.0% for anti-IL-17) compared to patients on topical therapy (7.3%), but statistically significant only for anti-IL-17 (p<0.05). The presence of oral HPV infection in patients treated with biologics was significantly higher (44.0%) in patients on long-term biologic treatment (>8 years) compared to patients taking biologics for a shorter period (9.1%; p<0.01). Our results suggest that patients on biologics for psoriasis have a higher prevalence of oral HPV infection compared to patients on topical treatment. Long-term treatment with biologics seems to be associated with a higher prevalence of oral HPV infection, independent of previous conventional immunosuppressive therapy.

The impact of systemic psoriasis treatments on human papillomavirus activation and propagation

Psoriasis is one of the most prevalent diseases in the world and it affects up to 2% of the worldwide population. Its pathogenesis is complex and the lesions may be triggered by multiple factors. Human papillomavirus (HPV) is associated with anogenital cancers, cutaneous warts and is considered one of the most prevalent infections in the world. In this review, the available literature on the systemic treatment of patients with psoriasis and concomitant HPV infection was analysed.

Increased risk of genital warts in inflammatory bowel disease: A Danish registry-based cohort study (1996-2018)

Background

Patients with inflammatory bowel disease (IBD) are at increased risk of human papillomavirus (HPV) related cancers such as anal squamous cell carcinoma. However, risk of non‐malignant HPV infection has never been systematically studied in IBD. This study aims to assess the risk of genital warts (GW) in IBD patients.

Methods

Using the Danish nationwide registries, we identified 49,163 patients with IBD between 1996 and 2018 and matched them to 491,665 individuals from the general population by age, sex, and HPV immunisation. Cumulative incidence rates for GW in IBD and non‐IBD patients were calculated by age. Cox proportional regression analysis was used to calculate hazard ratios (HR) for GW in IBD compared to matched population and in Crohn's disease (CD) compared to ulcerative colitis (UC). We undertook subgroup analysis for risk of GW by sex, year of IBD diagnosis, contraceptive exposure and IBD treatment exposure.

Results

The fully adjusted HR for GW in IBD patients compared to the matched non‐IBD population was 1.33 (95% CI: 1.19–1.49) and 1.13 (95% CI: 1.01, 1.27) in CD as compared to UC. This increased risk was particularly observed in female (HR: 1.54, 95% CI: 1.33–1.79) over male (HR: 1.14, 95% CI: 0.97–1.34) IBD patients, but was also found across all periods of diagnosis with IBD, regardless of contraceptive treatment exposure, and also seen in IBD patients who had never been exposed to immunosuppressive treatment (HR: 1.33, 95% CI: 1.19–1.49).

Conclusion

In this nationwide, population‐representative cohort study, we observed a 33% increased risk of GW in patients with IBD compared to the matched population and a 13% increased risk of GW in CD compared with UC. This risk was particularly increased in female over male IBD patients and seen independent of IBD treatment exposure.

Human papillomavirus infection with anogenital warts in a patient with chronic psoriasis: A case report

Psoriasis is a chronic inflammatory disease with characteristic skin manifestations. Several pathogens can cause flare-ups of psoriasis. The risks of skin infections are increased in patients receiving immunomodulators. A patient with chronic psoriasis presented with human papillomavirus infection and anogenital warts and was treated surgically with acceptable results.

Viral infections in inflammatory bowel disease: Tips and tricks for correct management

Over the past decades, the treatment of inflammatory bowel diseases (IBD) has become more targeted, anticipating the use of immune-modifying therapies at an earlier stage. This top-down approach has been correlated with favorable short and long-term outcomes, but it has also brought with it concerns regarding potential infectious complications. This large IBD population treated with immune-modifying therapies, especially if combined, has an increased risk of severe infections, including opportunistic infections that are sustained by viral, bacterial, parasitic, and fungal agents. Viral infections have emerged as a focal safety concern in patients with IBD, representing a challenge for the clinician: they are often difficult to diagnose and are associated with significant morbidity and mortality. The first step is to improve effective preventive strategies, such as applying vaccination protocols, adopt adequate prophylaxis and educate patients about potential risk factors. Since viral infections in immunosuppressed patients may present atypical signs and symptoms, the challenges for the gastroenterologist are to suspect, recognize and diagnose such complications. Appropriate treatment of common viral infections allows us to minimize their impact on disease outcomes and patients’ lives. This practical review supports this standard of care to improve knowledge in this subject area.

Multidisciplinary, evidence-based consensus guidelines for human papillomavirus (HPV) vaccination in high-risk populations, Spain, 2016

Introduction: Although human papillomavirus (HPV) routine vaccination programmes have been implemented around the world and recommendations have been expanded to include other high-risk individuals, current recommendations often differ between countries in Europe, as well as worldwide.

Aim: To find and summarise the best available evidence of HPV vaccination in high-risk patients aiding clinicians and public health workers in the day-to-day vaccine decisions relating to HPV in Spain.

Methods: We conducted a systematic review of the immunogenicity, safety and efficacy/effectiveness of HPV vaccination in high-risk populations between January 2006 and June 2016. HPV vaccination recommendations were established with levels of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

Results: A strong recommendation about HPV vaccination was made in the following groups: HIV infected patients aged 9–26 years; men who have sex with men aged 9–26 years; women with precancerous cervical lesions; patients with congenital bone marrow failure syndrome; women who have received a solid organ transplant or hematopoietic stem cell transplantation aged 9–26 years; and patients diagnosed with recurrent respiratory papillomatosis.

Conclusions: Data concerning non-routine HPV vaccination in populations with a high risk of HPV infection and associated lesions were scarce. We have developed a document to evaluate and establish evidence-based guidelines on HPV vaccination in high-risk populations in Spain, based on best available scientific evidence.
