Re-Evaluation of Annual Cytology Using HPV Testing to Upgrade Prevention in Women Living With HIV

2019-11-12 18:25:32 | BioPortfolio

Summary

Current British HIV Association (BHIVA) guidelines recommend annual cervical screening (with a cervical smear) for women living with HIV (WLWH). NHS guidelines for women in England will, however, change soon. Women will initially be tested for human papilloma virus (HPV), a virus which causes virtually all cervical cancer. Only those who are infected with HPV will then undergo the smear testing. The BHIVA guidelines, however, taking the view that HIV infection (and its ability to weaken the immune system) increases the risk of persistent HPV infection and of cancer in those who are infected, consider safer for all WLWH to go straight to annual smear testing. Most WLWH in the UK are now receiving treatment which protects their immune system - this suggests that less WLWH could be HPV infected. The identification of a group of WLWH who could benefit from less frequent screening could improve quality of life, and allow the NHS to reduce unnecessary tests and costs. A large study is needed to collect robust evidence that would support changes to standard practice. Before investing huge resources, the investigators need to know if a study would be feasible, conducting a pilot study on 70 WLWH aged 25-64, regularly attending clinics for HIV care. Participants will be asked to complete an entry survey and they will undergo routine cervical smears (baseline and after 1 year). At baseline, after six months, and one year women will take their own vaginal swabs for the detection of HR-HPV. An exit questionnaire will be undertaken at the last visit.

Description

This pilot study will enrol 70 WLWH aged 25-64, with no history of cervical abnormalities attending 4 HIV clinics in the UK. Participants will be asked to complete an entry survey in which behavioural information, gynaecological and sexual history, will be collected, with the aim of characterising the study population for the risk factors of HPV infection. Women's attitude towards the current cervical screening and their view on a change to HPV testing will also be assessed. Participants' relevant clinical data will be collected form their medical notes. Women will be instructed to perform a self-taken vaginal swab for the detection of HR HPV while in clinic, and they will be reminded of the annual cervical smear (which can be offered in clinic or performed at their GP practice as per local policy). After six months, women will be asked to take another vaginal swab; this can be offered in clinic, during the regular HIV follow up, or can be sent via the post. Another sample for HR-HPV testing will be collected one year later, at the next routine HIV appointment. The annual smear test will be due and this will be offered in clinic or done at the GP practice, according to local policies. After this visit, an exit questionnaire will be undertaken to evaluate the acceptability of the study procedures.

Medical and Biotech [MESH] Definitions

Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.

A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.

A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.

Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck.
