OBJECTIVE: The protective effect of ART has not yet been definitively established in men who have sex with men (MSM). We aimed to characterize the factors associated with persistent HIV-1 RNA rectal shedding. METHODS: Prospective study including virologically-suppressed MSM from an HIV cohort. High-resolution anoscopy (HRA) was performed for screening of anal dysplasia, and rectal sampling for HIV-1 RNA quantification and sexually-transmitted infections (STIs) investigation through multiplex PCR...

A 48-year-old man presented as an emergency with a 3-week history of rectal bleeding. Examination of his rectum revealed a circumferential tumour, 2 cm from the anal verge. An MRI scan reported a locally infiltrative mid-lower rectal tumour staged as T3d/T4 N2 MX. A colonoscopy revealed appearances of severe proctitis and biopsies did not show any evidence of dysplasia or malignancy. The patient was discussed at the regional colorectal cancer multidisciplinary team meeting with a management plan for neoadjuvant chemoradiotherapy following repeat biopsies, which were again negative for malignancy...

The prevalence of Human Papillomavirus (HPV) in men who have sex with men (MSM) is high, reaching 85-93% prevalence in HIV-positive men. High-risk HPV are strongly associated with development of high degrees of anal intraepithelial neoplasia (AIN) which, later on, can develop in anal squamous carcinoma. The growing incidence of anal cancer during last years is particularly important in MSM and HIV-positive patients, in which the coexistence of multiple serotypes of HPV reduces the probability of eliminating the AIN...

BACKGROUND: Sexually transmitted infection (STI) rates are increasing in the U.S. while funding for prevention and treatment programs has declined. Sample self-collection for STI testing in men may provide an acceptable, easy, rapid and potentially cost-effective method for increasing diagnosis and treatment of STIs. METHODS: We conducted a systematic review of articles assessing self-collection of anal, oral, or genital swab samples among adult men for detection of STIs and/or human papillomavirus (HPV)-related dysplasia...

Background: Ulcerative colitis (UC) is an idiopathic inflammatory disorder. Currently, the final treatment is colectomy. The aim of this study was to investigate the outcomes of proctocolectomy in patients that used a high dose of prednisolone. Materials and Methods: Seventy-five patients presenting for surgical management of histopathologically proven UC. All patients were offered total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA). Patients were divided into two groups: low dose of steroids (Group A) and high dose of steroid (Group B) consumers...

PURPOSE OF REVIEW: As access to effective antiretroviral therapy (ART) expands globally, a decline in AIDS-related morbidity and mortality has been complicated by rising rates of noncommunicable diseases (NCDs). This review provides a brief description of NCDs and existing gaps on knowledge about NCDs among HIV-infected adults mostly in Africa. RECENT FINDINGS: Recent reports show that one in every five persons living with HIV has a chronic illness, predominantly diabetes and/or hypertension, depression, and most of these conditions are either not diagnosed or not being managed...

Chronic pouchitis (CP) after ileal pouch-anal anastomosis is a significant clinical problem. Adipose tissues produce antiinflammatory cytokines and chemokines. We evaluated the association between abdominal visceral fat area (VFA) and CP. Patients with a preoperative CT evaluation were included. The diagnosis of CP was confirmed in all cases by endoscopy with afferent ileal limb intubation. Patients were allocated into groups of high VFA and low VFA. The study cohort of 52 patients had a median body mass index of 22 (range, 14-32)...

BACKGROUND: Imiquimod can be used to treat internal anal high-grade squamous intraepithelial lesions. In HIV-1-infected individuals there is a theoretical concern for increased HIV replication in anorectal tissue secondary to imiquimod-induced mucosal inflammation. OBJECTIVE: The purpose of this study was to assess local virologic, immunologic, and pathologic effects of imiquimod treatment in HIV-infected individuals. DESIGN: This was a pilot study at a single academic center...

Endoscopic mucosal resection and endoscopic submucosal dissection (ESD) are operative endoscopies that have been performed since a long time. Recently, an evolution of laparoscopy called transanal minimally invasive surgery began to be popularized, and it can be adopted in the face of difficult cases for endoscopic mucosal resection/ESD. In this video, a 36-year-old woman was submitted to transanal minimally invasive surgery resection, after unsuccessful ESD, for a 2-cm polyp located anteriorly in the anal canal, just beyond the pectineal line...

INTRODUCTION: Anal cancer is one of the most common non-AIDS defining malignancies, especially in men who have sex with men and women living with HIV (WLHIV). OBJECTIVES: To evaluate the prevalence and incidence of precursor lesions (high-grade squamous intraepithelial lesions [HSIL]) and anal cancer in our cohort of women and to compare them to cervical lesions; to calculate the percentage of patients that acquire and clear oncogenic genotypes (HR-HPV) in the anal canal; and to determine predictive factors for anal HPV infection...

The epidemiology of anal cancer in the U.S. has changed over the past 3 decades. During this period the incidence of anal cancer has increased among both men and women. Of note, women with a history of anogenital HPV infection are at higher risk than the general population for anal cancer. The increased risk ranged from increased incidence rate ratios ranging from 1.82 to 6.3 in women with a history of cervical cancer, to 4.2-16.4 in women with a history of prior cervical intraepithelial neoplasia 3 (CIN 3)...

BACKGROUND: Transanal minimally invasive surgery (TAMIS) has emerged as a relatively new technique in treating early cancer and benign lesion of the rectum. The technique is likely to be widely adopted, surpassing other comparable techniques owing to its simple setup and cost-effectiveness. We assessed the outcomes of TAMIS at our centre. METHODS: We retrospectively reviewed prospectively collected data on 50 patients who underwent TAMIS for benign, malignant T1 or T2 cancers that were unfit for radical surgery over a 4-year period...

BACKGROUND AND AIM: The human papilloma virus is the leading cause of anal squamous cell carcinoma. Cytological screening may reduce the associated morbidity and mortality. The aim of the study was to estimate the agreement between anal cytological examination, histopathology and anoscopic visual impression. METHODS: A prospective study of patients who underwent anal dysplasia screening between 2011 and 2015, in a proctology clinic of a tertiary referral center...

Human papilloma virus positive (HPV+) tumors represent a large proportion of anal, vulvar, vaginal, cervical and head and neck squamous carcinomas (HNSCC) and late stage invasive disease is thought to originate from a premalignant state. Cyclic dinucleotides that activate STimulator of INterferon Genes (STING) have been shown to cause rapid regression of a range of advanced tumors. We aimed to investigate STING ligands as a novel treatment for papilloma. We tested therapies in a spontaneous mouse model of papilloma of the face and anogenital region that histologically resembles human HPV-associated papilloma...
