Efficacy of carboxymethyl beta-glucan in cervical intraepithelial neoplasia: a retrospective, case-control study.

Background: Persistent human papillomavirus (HPV) infection constitutes the principal risk factor for the development of cervical intraepithelial neoplasia (CIN) and cervical cancer. For this reason, new drugs have been studied to support the host immune system against the HPV infection. The aim of this retrospective, case-control study was to detect the efficacy and safety of carboxymethyl β-glucan (Colpofix®) gel as adjuvant therapy in HPV infection.

TLR9 is expressed in human papillomavirus-positive cervical cells and is overexpressed in persistent infections.

Control of human papillomavirus (HPV) infection involves the activation of Toll-like receptors (TLRs), key components of the mucosal antiviral response. Available studies on TLR expression in HPV-positive cervical cells are limited and reported conflicting results. This study quantified TLR 2, 3, 4, 7 and 9 transcripts in low-risk (LR) and high-risk (HR) HPV-positive and HPV-negative cervical samples from 154 women attending a gynaecological clinic.

Interferon lambda 1 expression in cervical cells differs between low-risk and high-risk human papillomavirus-positive women.

Persistent infection by high-risk (HR) human papillomavirus (HPV) types is a prerequisite for progression to cancer. HR-HPVs may lead to a deregulation of innate immunity by interfering with the epithelial type I interferon (IFN) response, whereas very little is known about type III IFNs, a key component of the mucosal antiviral response. This study reports a first attempt to evaluate the activation of type III IFN genes (IFN lambda 1-3), IFN lambda receptor genes (IFN-lambdaR1 and IL10R2), and IFN-induced genes (MxA, ISG15, ISG56) in HPV-positive and HPV-negative cervical cells from 154 women attending the gynecological unit of a university hospital in Rome.

Lack of association between genetic variants in the mannose-binding lectin 2 (MBL2) gene and HPV infection.

Genetic variants in the immunomodulatory gene mannose-binding lectin 2 (MBL2), were associated with risk, severity, and frequency of viral infections. In a case-control setting, we investigated the association of MBL2 functional polymorphisms with Human Papillomas Virus (HPV) infection. No differences between cases (HPV(+)) and controls (HPV(-)) were found in the distribution of each single genotypes or allele.

Young women, cervical intraepithelial neoplasia and human papillomavirus: risk factors for persistence and recurrence.

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections (STIs) in young women. They can occur in one or multiple areas of the female genitalia. Usually, the vulva is the initial site of implantation for HPV.

Human papillomavirus in virgins and behaviour at risk.

Human papillomavirus (HPV) infection is one of the most common sexual transmitted diseases (STDs). We compared two groups of virgins with genital HPV lesions to evaluate the behaviour at risk in the transmission of HPV infection. Partners were also examined.

Giant condyloma acuminatum or buschke-Lowenstein tumor: review of the literature and report of three cases treated by CO2 laser surgery. A long-term follow-up.

Giant condyloma acuminatum or Buschke-Lowenstein tumor (TBL) is a rare disease that arises on the male and female external genitalia. TBL arises from the confluence of multiple condylomata acuminata and it is induced a Human Papillomavirus infection. TBL presents a clinical malignancy, but it is known to be a histologically benign tumor, even if it carries a risk of malignant transformation.
