Incidence of adult primary immune thrombocytopenia in England-An update.

BACKGROUND: Adult primary immune thrombocytopenia (ITP) is a rare bleeding disorder of unknown cause. Recent estimates of its incidence and trend over time were acquired for England. METHOD: The primary ITP population (using ICD 10 code D693 and excluding secondary ITP cases; positive predictive value: 82.6%) was sourced from NHS Digital inpatient and outpatient. Incidence rate (IR) for England and by age groups, sex, and regions were calculated and trends were assessed using average annual percent change (AAPC). RESULTS: A total of 25 805 patients (mean age 59 years; females 57.8%) diagnosed between 2003 and 2014 was identified. IRs increased from 4.2/100 000 to 6.4/100 000 over this period (AAPC:4.3%). For all sex-specific age groups, the IRs significantly increased over time, except 18-29 years males. The greatest increase was among females aged 30-39 (AAPC:8.7%). In contrast, among ≥70 years, ITP was more common in males (highest IR among ≥80 years males: 23.9/100 000). England's average annual IR was 6.1/100 000 for 2010-14. An estimated 2.5/100 000 (based on UKITP Registry data) was estimated to require 1st line treatment whereas 2.4/100 000 would have 1st and 2nd line treatments within 6 months from diagnosis. IRs for London and East Midlands were the highest (6.5/100 000). CONCLUSIONS: This study found a rising incidence of primary ITP, with sharp increases among young women and elderly men. These findings put in context the impact of ITP on patients' lives and the healthcare services in England, especially with 17%-50% who may develop chronic ITP and require long-term care.

Awareness of the link between human papillomavirus and oral cancer in UK university students.

Awareness of the link between human papillomavirus (HPV) and oral cancer varies across populations. Levels of awareness and factors may impact HPV vaccine uptake in women and the intent to obtain the vaccine in men if it becomes available. A cross-sectional survey of 1415 UK university students (495 men and 920 women) aged 18-25 years was conducted. Women who had and had not received the HPV vaccine were included. Vaccination was not available for men at the time of the survey. Seventy percent of participants had heard of oral cancer but only 25% were aware of the link between HPV and oral cancer. Women who ever engaged in sexual activity (adjusted odds ratio, aOR = 1.74; 95% CI: 1.12-2.72) or had at least one dose of the HPV vaccine (aOR = 1.71; 95% CI: 1.24-2.37) were more likely to be aware. Men who intend to receive the HPV vaccine in the future were more likely to be aware (aOR = 1.62; 95% CI: 1.04-2.53). Non-white women were less likely to be vaccinated (aOR = 0.56; 95% CI: 0.41-0.77). However, being aware was associated with HPV vaccine uptake in women (aOR = 1.65; 95% CI: 1.19-2.28) and borderline associated with the intent to obtain the HPV vaccine in men (aOR = 1.52; 95% CI: 0.99-2.35). Non-heterosexual men were more willing than heterosexuals to receive the vaccine. Following the UK gender-neutral HPV vaccination programme, there is an opportunity to increase awareness about the link between HPV and oral cancers aside from the cervical cancer link to influence HPV vaccine uptake.
