PurposeOur aims are to: (1) estimate prevalence, incidence, clearance and persistence of oral human papillomavirus (HPV) infection among Indigenous Australians; (2) identify risk factors associated with oropharyngeal squamous cell carcinoma (OPSCC)-related HPV types (HPV 16 or 18); (3) develop HPV-related health state valuations and; (4) determine the impact on OPSCC and cervical cancers, and the cost-effectiveness of extending publicly-funded HPV vaccination among Indigenous Australians.ParticipantsParticipants were recruited from February 2018 to January 2019. Twelve-month follow-up occurred from March 2019 to March 2020. Participants provided socio-demographic characteristics, health-related behaviours including tobacco and alcohol use and sexual history. Health state preferences in regard to HPV vaccination, knowledge regarding HPV infection, OPSCC and cervical cancer were collected using a two-stage standard gamble approach. Participants provided saliva samples and DNA for microbial genotyping was extracted.Findings to dateOf the 910 participants who were positive for β-globin at baseline, 35% had any oral HPV infection. The most prevalent HPV types were 13 or 32 (Heck’s disease; 23%). The second most prevalent types were associated with OPSCC (HPV 16 or 18; 3.3%). Of the 645 participants who were positive for β-globin at 12-month follow-up, 43% had any HPV infection. Of these, 33% were HPV types 13 or 32 and 2.5% were HPV 16 or 18. Some 588 participants had β-globin positive oral samples at baseline and 12-month follow-up. The prevalence of any oral HPV infection increased from 34% at baseline to 44% at 12-month follow-up; due to increases in HPV types 13 or 32 (20% at baseline and 34% at 12-month follow-up).Future plansFurther funding will be sought to continue follow-up of this cohort, and to include (after a full medical history) a thorough clinical examination of the external head and neck; a complete oral examination and examination of the oropharynx. Blood tests for early stage OPSCC will also be undertaken.

Abstract Background Human papillomavirus–related oropharyngeal cancer (HPV-OPC) incidence is increasing, but the natural history of the precursor—oral HPV—has not been well described. Methods This observational cohort study of people living with HIV and at-risk HIV uninfected people evaluated participants semiannually using 30-second oral rinse and gargle specimens over 7 years. Initially, 447 participants were followed for 4 years as part of the Persistent Oral Papillomavirus Study, and a subset of 128 who showed persistent infections at the last Persistent Oral Papillomavirus Study visit had an additional visit, as part of the Men and Women Understanding Throat HPV Study, on average 2.5 years later. Extracted DNA from oral rinse and gargle specimens was amplified using polymerase chain reaction and type specification of 13 oncogenic HPV types. Risk factors for oncogenic oral HPV clearance were evaluated using Cox models. Results The majority of oncogenic oral HPV infections cleared quickly, with a median time to clearance of 1.4 years (interquartile range = 0.5-3.9 years). After 7 years of follow-up, 97% of incident and 71% of prevalent infections had cleared. Lower HPV-16 viral load was statistically significantly associated with clearance (per 10-fold decrease in copy number: adjusted hazard ratio [aHR] = 2.51, 95% confidence interval [CI] = 1.20 to 5.26; P = .01). Adjusted analyses showed that oncogenic oral HPV clearance was lower among prevalent than incident-detected infections (aHR = 0.44, 95% CI = 0.35 to 0.55), among men than women (aHR = 0.74, 95% CI = 0.60 to 0.91), for older participants (aHR per 10 years increasing age = 0.81, 95% CI = 0.74 to 0.89), and among people living with HIV (aHR = 0.76, 95% CI = 0.60 to 0.95). One participant who had oral HPV-16 consistently detected at 10 study visits over 4.5 years was subsequently diagnosed with HPV-OPC. Conclusions This prospective study of oncogenic oral HPV infection is the longest and largest quantification of oral HPV-16 infections to date.

This study aimed to document the types, management and follow up of health issues identified by all Aboriginal Health Assessments (AHA) performed at Orange Aboriginal Medical Service from 1 January 2011 to 31 December 2012. This was done with a retrospective audit of clinical records. In total, 1169 AHAs were performed: 41% child, 53% adult and 6% older person AHAs. Newly identified health issues were documented in 85% (984). Being overweight (41%; 476) and smoking (26%; 301) were the common risk factors identified. As a result of the AHA, most children who were not up-to-date with their vaccinations received catch-up immunisations; 11% (36) of adult women (n=314) received a Pap smear, although Pap smear status was unknown or not up-to-date for 61% (192); 27% (311) of cases were prescribed new medication; and 1239 referrals were made but only 40% were attended. At 6 months following the AHA, 26% (240) of cases with newly identified health issues were completely managed and followed up, whereas 25% (226) received no follow up. The AHAs are useful for identifying new health issues; however, follow up of the identified health issues should be improved. If AHAs are to improve health outcomes, appropriate management and follow up of the identified health issues are essential.

Indigenous Australians are disproportionally affected by hepatitis B compared with non-Indigenous Australians. The higher prevalence of hepatitis B among Indigenous Australians has been linked to an increased incidence of liver cancer in this population. There is evidence that comprehensive programs of hepatitis B virus management, which include liver cancer surveillance and appropriate antiviral therapy, offer a cost-effective approach to reduce the incidence of liver cancer in Australia. This paper reports on data from the first study investigating understandings of hepatitis B and attitudes to treatment among Torres Strait Islanders living with chronic hepatitis B. Forty-two participants completed an interview questionnaire. Participants typically had an unclear understanding of hepatitis B and reported significant gaps in monitoring and follow up. A majority of participants indicated a willingness to use treatment if required. The findings of this study suggest the need for a new service delivery model that is appropriate to remote communities such as the Torres Strait Islands, to improve hepatitis B follow up, disease monitoring and management, and where appropriate, the uptake of treatment.

Abstract Background: Genetic factors may influence the susceptibility to high-risk human papillomavirus (hrHPV) infection and persistence. We conducted the first genome-wide association study (GWAS) to identify variants associated with cervical hrHPV infection and persistence. Methods: Participants were 517 Nigerian women evaluated at baseline and 6 months follow-up visits for HPV. HPV was characterized using SPF10/LiPA25. hrHPV infection was positive if at least one carcinogenic HPV genotype was detected in a sample provided at the baseline visit and persistent if at least one carcinogenic HPV genotype was detected in each of the samples provided at the baseline and follow-up visits. Genotyping was done using the Illumina Multi-Ethnic Genotyping Array (MEGA) and imputation was done using the African Genome Resources Haplotype Reference Panel. Association analysis was done under additive genetic models adjusted for age, HIV status and the first principal component (PC) of the genotypes. Results: The mean (±SD) age of the study participants was 38 (±8) years, 48% were HIV negative, 24% were hrHPV positive and 10% had persistent hrHPV infections. The top three variants associated with hrHPV infections were intronic variants clustered in KLF12 (all OR: 7.06, p=1.43 x 10-6). The top variants associated with cervical hrHPV persistence were in DAP(OR: 6.86, p=7.15 x 10-8), NR5A2(OR: 3.65, p=2.03 x 10-7) and MIR365-2(OR: 7.71, p=2.63 x 10-7) gene regions. Conclusions: This exploratory GWAS yielded novel candidate risk loci for cervical hrHPV infection and persistence. The identified loci have biological annotation and functional data supporting their role in hrHPV infection and persistence. Given our limited sample size, larger discovery and replication studies are warranted to further characterize the reported associations.
