Various cranial nerve disorders are known to occur after HPV viral infections. However, studies on the relationship between human papillomavirus vaccination and cranial nerve disorders are limited. Here, we aimed to evaluate the association between human papillomavirus vaccination and risks of cranial nerve disorders in young girls. We enrolled 261,111 women aged between 9 and 26 years, and they had received HPV vaccination between January 2018 and December 2022. These subjects were compared with those controls who never received HPV vaccination using a propensity score-matched (1:1) based on the TriNetX U.S. Collaborative Network. Risks on incidences of various cranial nerve disorders were evaluated. Subgroup and sensitivity analyses were also performed. The HPV-vaccinated cohort, on one hand, had significantly lower risks on hearing loss (aHR:0.490, 95% CI:0.419-0.572), facial nerve disorders (aHR:0.690, 95% CI:0.522-0.912); disorders of vestibular function disorders (aHR:0.523, 95% CI:0.422-0.647); and similarly on other inner ear disorders (aHR:0.537, 95% CI:0.392-0.735) and trigeminal nerve disorders (aHR:0.328, 95% CI:0.200-0.538). On the other hand, the HPV-vaccinated cohort had significantly higher risks of odor and taste disorders (aHR: 3.136, 95% CI: 0 2.562-3.840). Kaplan-Meier curves of different cranial nerve disorders also revealed significant probability disparities between the two cohorts (Log–Rank test, p < 0.001). In conclusion, for females between 9 and 26 years old, their HPV vaccination was associated with on one hand, lower risks of cranial nerve disorders, like hearing loss, vestibular function/other diseases of the inner ear, facial nerve disorders, and disorders of the trigeminal nerve, and on the other hand, higher risks on smell and taste disorders, as revealed over a year-long follow-up period. Health sciences/Health care/Public health/Epidemiology Health sciences/Medical research/Epidemiology Human papillomavirus vaccine Cranial nerve disorders TriNetx Cohort study Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Introduction Human papillomavirus (HPV) is a small double-stranded DNA virus. HPV infection is becoming more common in recent years. Some specific subtypes of HPV infection are associated with various diseases, like cervical, head and neck, breast, lung, and anogenital cancers, and autoimmune diseases 1 – 4 . Today, 3 vaccines for Human papillomavirus have been reported prevent HPV infection and precancer lesions of cervical disease 4 . For example, Gardasil, a quadrivalent vaccine (Merck & Co., Kenilworth, NJ, USA), which targets HPV types 6,11,16, and 18, is the first commercially available HPV vaccine. It was licensed by the United States Food and Drug Administration (FDA) in 2006. Cervarix, a bivalent HPV vaccine (GSK, Brentford, UK) was also approved by FDA in 2009. It protects against the HPV type 16 and 18. Finally, Gardasil 9, a 9-valent vaccine (Merck & Co., Kenilworth, NJ, USA), was licensed by FDA in 2014. It protects against HPV 6, 11, 16, 18, 31, 33, 45, 53, and 58 2,4 . To date, the virus-like particle (VLP) of papillomavirus capsid protein L1, constitutes the HPV vaccines. VLP is produced from bacteria or yeast containing only protein without viral genomes. They are considered non-infectious and non-carcinogenic and are considered safer than those attenuated HPV vaccines. The World Health Organization currently recommends that girls aged 9 to 14 years are prioritized for HPV vaccination before their first sexual exposure 5 . Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) recommends that HPV vaccination can start at the age of 9 through 26 years old, for those not vaccinated before 6 . Viral infections are widespread and difficult to control. Various cranial nerve disorders due to viral infections are well-known, such as smell and taste dysfunction after COVID-19 infection 7 , 8 ; facial nerve paralysis after varicella-zoster virus infection, or human herpesvirus 6 infection 9 ; hearing impairment after human cytomegalovirus infection 10 , 11 ; and Zika virus infection after inner ear disease 12 . Knowledge on the relationship between human papillomavirus vaccination and cranial nerve disorders remains limited from the literature review. Here, we aimed to evaluate the association between young girls receiving the human papillomavirus vaccine and their risk of developing cranial nerve disorders. Results Characteristics of study subjects Table 1 shows baseline characteristics of the study subjects including their demographic characteristics, lifestyle, comorbidities, and medication usage of both the HPV-vaccinated cohort and the control cohort, before and after matching. Before matching, we found significant differences in two cohorts in terms of the following: age at index, race of white and black or African American, the emergency department services, comorbidities including certain infectious and parasitic diseases, noninflammatory disorders of female genital tract, disease of middle ear and mastoid, asthma, overweight and obesity, disorders of lipoprotein metabolism and other lipidemia, injuries to the head, depressive episode, anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders, sleep disorders, and Ibuprofen usage. After matching, the two cohorts were matched well as their differences were within the acceptable range (SMD < 0.1). After propensity score matching, the HPV-vaccinated cohort (N = 261,111) and the control group with no HPV vaccination (N = 261,111) were further compared.

Incidence of cranial nerve disorders in the HPV-vaccinated and control groups Table 2 shows risks of cranial nerve disorders in both the HPV-vaccinated and control groups revealed during a yearlong follow-up. The HPV-vaccinated cohort had significantly lower risks of the following: hearing loss (aHR:0.490, 95% CI:0.419–0.572), including bilateral sensorineural hearing loss (aHR:0.472, 95% CI:0.384–0.581), sensorineural hearing loss, unilateral with unrestricted hearing (aHR:0.532, 95% CI:0.397–0.715), and sensorineural hearing loss, unspecified (aHR:0.472, 95% CI:0.351–0.634); facial nerve disorders (aHR:0.690, 95% CI:0.522–0.912); disorders of vestibular function (aHR:0.523, 95% CI:0.422–0.647); other diseases of inner ear (aHR:0.537, 95% CI:0.392–0.735) including labyrinthine dysfunction (aHR:0.382, 95% CI:0.246–0.591); and disorders of trigeminal nerve (aHR:0.328, 95% CI:0.200-0.538). At the same time, the HPV-vaccinated cohort showed significantly higher risks in disturbances of smell and taste (aHR: 3.136, 95% CI:0. 2.562–3.840), including anosmia/ parosmia (aHR: 3.212, 95% CI: 0.2.415–4.273) and parageusia (aHR: 5.416, 95% CI: 3.762–7.796). Kaplan–Meier curves of different cranial nerve disorders similarly revealed significant inter-cohort differences in probability (Log–Rank test, Table 2 Risk of outcome (1 days to 1y) Outcomes Patients with outcome Adjusted hazard ratio (95% CI) a HPV vaccinated cohort Control cohort Hearing loss 241 470 0.490 (0.419–0.572) Sudden idiopathic hearing loss 12 11 1.038 (0.458–2.352) Sensorineural hearing loss, bilateral 134 271 0.472 (0.384–0.581) Sensorineural hearing loss, unilateral with unrestricted hearing 69 124 0.532 (0.397–0.715) Sensorineural hearing loss, unspecified 66 133 0.472 (0.351–0.634) Disturbances of smell and taste 405 122 3.136 (2.562–3.840) Anosmia and Parosmia 208 61 3.212 (2.415–4.273) Parageusia 195 34 5.416 (3.762–7.796) Facial nerve disorders 85 117 0.690 (0.522–0.912) Disorders of vestibular function 131 238 0.523 (0.422–0.647) Meniere's disease 10 10 0.750 (0.201–2.793) Benign paroxysmal vertigo 77 92 0.791 (0.584–1.070) Vestibular neuronitis 10 10 3.313 (0.688–15.94) Other diseases of inner ear 61 108 0.537 (0.392–0.735) Labyrinthitis 10 15 0.567 (0.248–1.296) Labyrinthine dysfunction 28 70 0.382 (0.246–0.591) Other specified diseases of inner ear 10 10 0.707 (0.245–2.038) Disease of inner ear, unspecified 10 10 0.482 (0.088–2.632) Disorders of trigeminal nerve 21 61 0.328 (0.200-0.538) Note: If the patient is less or equal to 10, results show the count as 10.

To eliminate covariate biases, Table S1 shows risks of cranial nerve disorders between the HPV-vaccinated cohort and the control cohort analyzed according to different models. Compared with the controls, patients receiving HPV vaccination had a lower incidence of different cranial nerve disorders including hearing loss, facial nerve disorders, disorders of vestibular function, other disease of inner ear, and disorders of trigeminal nerve in all models. Conversely, disturbances of smell and taste risk were higher in the HPV-vaccinated cohort. To evaluate effects of different follow-up periods, Table S2 shows risks of different cranial nerve disorders incidences in the two cohorts at different follow-up periods after HPV vaccination. We found again significantly lower risks of different cranial nerve disorders, including hearing loss, facial nerve disorders, disorders of vestibular function, other diseases of the inner ear and disorders of trigeminal nerve across different durations of follow-up (i.e., 1 day to 1 month, 1 day to 3 months, 1 day to 6 months, 1 day to 1 year, and 1 day to 3 years). Also, risks of disturbances of smell and taste were higher in patients receiving HPV vaccination across 3 different durations (i.e., 1 day to 3 months, 6 months, 1 year and 3 years). Subgroup Analyses Table S3 shows risks of different cranial nerve disorders in subgroups stratified according to age. In the subgroup with ages from 9 to 17 years, HPV vaccinated subjects showed lower risks of all cranial nerve disorders, except disturbances of smell and taste (aHR:3.362, 95% CI: 2.662–4.246), when compared with controls. On the other hand, the same trend was only observed in the subgroup aged from 18 to 26 years in disturbances of smell and taste (aHR:1.998, 95% CI: 1.393–2.866). Patients who had received HPV vaccination showed lower risks of various cranial nerve disorders, including hearing loss, facial nerve disorders, vestibular function, and other diseases of the inner ear, and higher risks of disturbances of smell and taste in the white and African/American races, while only significantly lower risk in hearing losses was found in the Asian subgroup ( Table S4 ). We also divided the HPV-vaccinated cohort into the 9v and 4v vaccines subgroups, and assessed the incidence of different cranial nerve disorders from 1 day to 1 year after the index date. Table S5 showed that the 9v subgroup had significantly lower risks of hearing loss, facial nerve disorders, vestibular function, other diseases of inner ear diseases, and disorders of trigeminal nerve disorders, and higher risks of disturbances of smell and taste. However, in the 4v subgroup, we observed a significant difference only observed in the lower risk of hearing loss (aHR: 0.264, 95% CI: 0.098–0.711) and the higher risk of disturbances of smell and taste (aHR: 18.00, 95% CI: 2.410–134.4). Sensitivity analyses To confirm the consistency of results, we used the same study design to compare data with the influenza vaccination group. In this sensitivity analysis, we found similarly lower risks of various cranial nerve disorders, including hearing loss, other diseases of the inner ear and disorders of the trigeminal nerve, and higher risks of disturbances of smell and taste compared with the influenza vaccine cohort ( Table S6 ). Discussion In this current large retrospective cohort study using EMR of multi-HCOs from TriNetx Network, we discovered that in women, aged from 9 to 26 years old, who had received HPV vaccination showed significantly lower risks of cranial nerve disorders including hearing loss(cranial nerve (CN.) 8th), vestibular function disorders or other inner ear diseases of the inner ear(CN. 8th), facial nerve disorders(CN. 7th), and trigeminal disorders of the trigeminal (CN. 5th) nerve during the yearlong follow-up period after HPV vaccination. In contrast, these same vaccinated patients had relatively higher risks of disturbances of smell and taste (the CN. 1st/5th,7th/9th). Risks of disturbance of smell and taste were significantly higher in the subgroup analysis based on age, race, and vaccine value when compared with the non-vaccinated cohort. Again based on subgroup analyses, cranial nerve disorders, like hearing loss/inner ear disease/vestibular functions (CN. 8), facial nerve (CN. 7), and trigeminal nerve (CN. 5) showed significantly lower risks in the subgroup of patients with from age 9 to 17 years, the 9-value of the HPV vaccine, white, and African/American (except disorder of trigeminal nerve). Pathophysiological mechanisms of Herpes papillomavirus infection on nerve disorders remain elusive. Previous research by Tibor Füle et al 13 suggested that HPV-16 is likely present in neuronal cells in the vascular endothelium as HPV 16 E6 ORF sequences are found in neuronal cells and endothelial cells of oral and cervical cancers. Shi et al propose a molecular mimicry hypothesis in that HPV infection results in immune dysregulation to systemic lupus erythematosus. According to other studies on the Guillain-Barré syndrome 14 , 15 , the molecular mimicry is one mechanisms of Guillain–Barré syndrome related to post-virus infection. A variety of viruses, like Campylobacter jejuni, cytomegalovirus, Haemophilus influenzae, Mycoplasma pneumoniae, Epstein-Barr virus, hepatitis E virus, influenza A virus, Zika virus, and HPV B19 have been reported to trigger demyelinating neuropathy 16 , 17 . On the other hand, Guo et al proposed that HPV virus may be latent in the central nerve system and become reactivated when the host is immunocompromised resulting in central or peripheral nerve neuropathy 17 . Despite scarce evidence in support of the association of human papillomavirus infection and cranial nerve disorders. Our results indicated that HPV vaccination could reduce HPV infection and lower risks of cranial nerve disorders. Regarding the higher risks of smell and taste dysfunction after HPV vaccination, the underlying mechanism is unclear. It is widely believed that smell and taste disorders often develop in patients with allergic rhinitis 18 , 19 . According to the study by Afrin et al, allergic reactions like nasal congestion and dysosmia after HPV vaccination could have triggered cytokine storm, especially involving mast cells or auto-antibodies that can act directly or indirectly on the vascular endothelium via the humoral immune system, in a condition related to the mast cell activation syndrome 20 . This process may be used to explain the risk disparity between disturbances of smell and taste and other cranial nerve disorders. Our study has several strengths. We used the TriNetX network, one of the largest databases, to conduct this first large retrospective cohort study to investigate for the first time, the association between HPV vaccination and various cranial nerve disorders during a relatively long-term follow-up period. Confounding biases including age, lifestyle habits, social economic status, medical utilization, and comorbidities were all eliminated using propensity score matching between the two cohorts. In addition, we performed subgroup analyses to determine possible effects of age, race, and vaccine valence on the results. Finally, sensitivity analysis was conducted using an influenza vaccination cohort verify the reliability of our HPV findings. Our study has several limitations. First, the study design, which was based on data from the electronic health records, had inherent weak points. The definition of cranial nerve disorders was based on the ICD-10-CM codes reported by physicians. The information may be have been incorrect due to misdiagnosis, underdiagnosis, inaccurate coding and documentation errors. Second, the database had no record on HPV antibody titers in those vaccinated patients, therefore we could not perform a further evaluation of the relationship between the antibody titer and cranial nerve disorders. Third, the database was derived mainly from patients with medical records from HCOs in the United States, and the number of patients diagnosed with cranial disorder was relatively small. Therefore, the representation of our conclusions is limited. Forth, we did not include all 12 cranial nerve-related disorders in our study. Future research is needed to explore different ethnic groups or databases. In conclusion, our preliminary results had suggested that HPV vaccination was associated with lower risks of a variety of cranial nerve disorders, including hearing loss, disorders of vestibular function/other diseases of the inner ear, facial nerve disorders, and disorders of the trigeminal nerve, but higher risks of disturbances of smell and taste in female aged between 9 to 26 years old over a yearlong follow-up. In addition, results were prominent in subgroups aged from 9 to 17 years, white, African American, and in patients who had received the 9-value HPV vaccine. These findings were consistent across follow-up periods of different lengths, and again valid when compared with the influenza vaccination cohort. Future research is needed to further investigate the complete set of cranial nerve disorders and to explore the underlying pathophysiological mechanisms. Methods Data source We obtained data from the TriNetX Analytics Network platform, which is a global federated health collaborative research network that has derived data from electronic medical records (EMR). The network provides data for ~ 250 million patients across 120 global healthcare organizations (HCOs). These organizations have collected web-based, real-time, secure patient electronic medical records. Each medical record contains information on International Classification of Disease, 10th Revision (ICD-10) diagnostic codes, procedures (Current procedural Terminology (CPT) codes, medications, laboratory test results, genomic information, and demographic data such as geography, age, gender, race, income, and insurance group. In this study, we utilized the U.S. Collaborative Network, which is a subset of the TriNetX database. Our study period was from January 1, 2018, till December 31, 2022. For details of the TriNetX, please visit its website: https://trinetx.com/ . Because we only used de-identified patient records and did not involve the collection, use, or transmission of personally identifiable data, our study was exempt from approval from our institutional review board. Our study also followed the Reporting guidelines of the Strengthened Reporting of Observational Studies in Epidemiology (STROBE). Our study was approved by the Institutional Review Board of Chung Shan Medical University Hospital, Taiwan (CSMUH No: CS2-21176). Study Population The study population included female patients aged from 9 to 26 years with at least two medical visits between January 1, 2018 and December 31 2022 as documented in the TriNetx Network. We excluded those diagnosed with oral cancers, HPV infection, or pregnancy. Based on EMR in the TriNetx Network, patients were divided into two groups: with HPV vaccination or without. The index date of the HPV vaccinated group was the date of completing vaccination (2-valent, 4-valent, or 9-valent), and the control group was the date of the first visit during the study period. We used the current procedural terminology (CPT) codes: 2-valent (90650), 4-valent (90649), and 9-valent (90651) to identify patients in the HPV-vaccinated group. TriNetx methodology in TriNetx is presented in Fig. 1 . Outcomes Main outcomes were the incidence of certain cranial nerve disorders defined according to ICD-10 codes, These disorders were as follows: (1) Hearing losses (ICD10 code H91.2 or CPT code 69801, H90.3, H90.4, H90.5) Sudden idiopathic hearing loss (ICD10 code H91.2 or CPT code 69801) Sensorineural hearing loss, bilateral (ICD10 code H90.3) Sensorineural hearing loss, unilateral with unrestricted hearing (ICD10 code H90.4) Sensorineural hearing loss, unspecified (ICD10 code H90.5) (2) Disturbances of smell and taste (ICD10 code R43) Anosmia, Parosmia (ICD10 code R43.0, R43.1) Parageusia (ICD10 code R43.2) (3) Facial nerve disorders (ICD10 code G51) (4) Disorders of vestibular function (ICD10 code H81) Meniere's disease (ICD10 code H81.0) Benign paroxysmal vertigo (ICD10 code H81.1) Vestibular neuronitis (ICD10 code H81.2) (5) Other inner ear diseases (ICD10 code H83) Labyrinthitis (ICD10 code H83.0) Labyrinthine dysfunction (ICD10 code H83.2) Other specified diseases of inner ear (ICD10 code H83.8) Disease of inner ear, unspecified (ICD10 code H83.9) (6) Disorders of trigeminal nerve (ICD10 code G50) To identify the time effect of vaccination, we also divided the risk of outcomes after HPV vaccination, in terms of 5 partially overlapping time periods after the index date follow-ups, namely: (a) 1 day to 1 month, (b) 1 day to 3 months, (c) 1 day to 6 months, (d) 1 day to 1 year and (e)1 day to 3 years. Covariates Demographic variables were the following: age, race, problems related to housing and economic circumstances (ICD 10 code Z59), and problems related to education and literacy (ICD 10 code Z55). Lifestyle variables included nicotine dependence (smoking) (ICD10 code F17, tobacco use (smoking) (ICD10 code Z72.0, alcohol related disorders (ICD10 code F10), and cannabis related disorders (ICD10 code F12). Medical utilization variables were office or other outpatient services, preventive medicine services, emergency department services, and hospitalization. These variables were identified by the International, Classification of Diseases (ICD) procedure codes (1013626, 1013829, 1013711, 1013659). Comorbidities included essential hypertension (ICD-10 code I10), ischemic heart diseases (ICD-10 code I20–I25), cerebrovascular diseases (ICD-10 code I60–I69), obesity (ICD-10 code E66), disorders of lipoprotein metabolism and other lipidemia (ICD-10 code E78.5), diabetes mellitus (ICD10 code E08-13), Other chronic obstructive pulmonary disease (ICD-10 code J44), asthma (ICD-10 code J45),chronic kidney diseases (ICD-10 code N18), liver diseases (ICD-10 code K70–K77), sleep disorders (ICD-10 code G47), transient cerebral ischemic attacks and related syndromes (ICD10 code G45), vascular syndromes of brain in cerebrovascular diseases (ICD10 code G46), periodontitis(ICD10 code K05), depression (ICD10 code F32), anxiety, traumatic past experiences, stress (ICD10 code F40-F48), certain infectious and parasitic diseases (ICD10 code A00-B99), neoplasms (ICD10 code C00-D49), blood diseases and disorders involving immune mechanisms (ICD10 code D50-D89), injuries to the head(ICD10 code S00-S09), rheumatoid arthritis (ICD10 code M05, M06, M08), systemic lupus erythematosus (SLE) (ICD10 code M32), and Sjogren’s syndrome (ICD10 code M35.0) To detect the presence of comorbidities, we traced back for one-year preceding period preceding the index date. The variables of medication usage included gentamicin (Anatomical Therapeutic Chemical (ATC) code S01AA11), streptomycin (ATC code J01GA01), cisplatin (ATC code L01XA01), carboplatin (ATC code L01XA02), cyclophosphamide (ATC code L01AA01), ibuprofen (ATC code G02CC01), naproxen (ATC code G02CC02), salicylates (aspirin, ATC code B01AC06), and sulfonamides (ATC code C03CA). Pure tone audiometry was identified by Current Procedural Terminology (CPT) code 1012899. Statistical Analyses All data analyses were performed on the TriNetX built-in platform and with the Advanced Analytics. Propensity score matching (PSM)was a 1:1 ratio, to balance all covariates between the two cohorts regarding demographics, lifestyles, medical utilization, comorbidities, and medication usage. The procedure was to reduce the impact of intervention selection bias. The balance of baseline characteristics in the propensity score-matched populations was evaluated based on standardized mean difference (SMD). With an absolute value of < 0.1, it was considered well-matched between the two cohorts. Kaplan–Meier analysis and log-rank tests were used to evaluate the probability of the outcomes and the difference of the survival curves between the two cohorts. The adjusted hazard ratio (aHR) was calculated to evaluate the relative risks of different cranial nerve disorders based on the time-to-event analysis for both the HPV-vaccinated and control groups. We used Cox proportional hazards models to calculate the hazard ratio (HR) and the associated 95% confidence interval (95%CI). R's Survival package v3.2–3 was used to calculate HR, 95% CIs, and the test for proportionality. The two-sided p-value < 0.05 was considered statistically significant. To evaluate the possible variables on the results after adjustment, we created 4 models for comparison. Subgroup analyses were based on age (≤ 9 to 17 years, and 18 to 26 years), race (white, African American and Asian), and different vaccine values (9v and 4v). We assessed differences in the risk of cranial nerve disorders across these subgroups during a year of follow-up following the index date. Finally, we also conducted a sensitivity test to compare the HPV vaccination and the influenza vaccination cohort with the same study design to verify the consistency of the results.

It protects against the HPV type 16 and 18. Finally, Gardasil 9, a 9-valent vaccine (Merck \u0026amp; Co., Kenilworth, NJ, USA), was licensed by FDA in 2014. It protects against HPV 6, 11, 16, 18, 31, 33, 45, 53, and 58\u003csup\u003e2,4\u003c/sup\u003e. To date, the virus-like particle (VLP) of papillomavirus capsid protein L1, constitutes the HPV vaccines. VLP is produced from bacteria or yeast containing only protein without viral genomes. They are considered non-infectious and non-carcinogenic and are considered safer than those attenuated HPV vaccines. The World Health Organization currently recommends that girls aged 9 to 14 years are prioritized for HPV vaccination before their first sexual exposure\u003csup\u003e\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e\u003c/sup\u003e.

We used the TriNetX network, one of the largest databases, to conduct this first large retrospective cohort study to investigate for the first time, the association between HPV vaccination and various cranial nerve disorders during a relatively long-term follow-up period. Confounding biases including age, lifestyle habits, social economic status, medical utilization, and comorbidities were all eliminated using propensity score matching between the two cohorts.

First, the study design, which was based on data from the electronic health records, had inherent weak points. The definition of cranial nerve disorders was based on the ICD-10-CM codes reported by physicians. The information may be have been incorrect due to misdiagnosis, underdiagnosis, inaccurate coding and documentation errors. Second, the database had no record on HPV antibody titers in those vaccinated patients, therefore we could not perform a further evaluation of the relationship between the antibody titer and cranial nerve disorders. Third, the database was derived mainly from patients with medical records from HCOs in the United States, and the number of patients diagnosed with cranial disorder was relatively small. Therefore, the representation of our conclusions is limited. Forth, we did not include all 12 cranial nerve-related disorders in our study. Future research is needed to explore different ethnic groups or databases.\u003c/p\u003e \u003cp\u003eIn conclusion, our preliminary results had suggested that HPV vaccination was associated with lower risks of a variety of cranial nerve disorders, including hearing loss, disorders of vestibular function/other diseases of the inner ear, facial nerve disorders, and disorders of the trigeminal nerve, but higher risks of disturbances of smell and taste in female aged between 9 to 26 years old over a yearlong follow-up. In addition, results were prominent in subgroups aged from 9 to 17 years, white, African American, and in patients who had received the 9-value HPV vaccine. These findings were consistent across follow-up periods of different lengths, and again valid when compared with the influenza vaccination cohort.

We excluded those diagnosed with oral cancers, HPV infection, or pregnancy. Based on EMR in the TriNetx Network, patients were divided into two groups: with HPV vaccination or without. The index date of the HPV vaccinated group was the date of completing vaccination (2-valent, 4-valent, or 9-valent), and the control group was the date of the first visit during the study period. We used the current procedural terminology (CPT) codes: 2-valent (90650), 4-valent (90649), and 9-valent (90651) to identify patients in the HPV-vaccinated group.

Lifestyle variables included nicotine dependence (smoking) (ICD10 code F17, tobacco use (smoking) (ICD10 code Z72.0, alcohol related disorders (ICD10 code F10), and cannabis related disorders (ICD10 code F12). Medical utilization variables were office or other outpatient services, preventive medicine services, emergency department services, and hospitalization.

Propensity score matching (PSM)was a 1:1 ratio, to balance all covariates between the two cohorts regarding demographics, lifestyles, medical utilization, comorbidities, and medication usage. The procedure was to reduce the impact of intervention selection bias. The balance of baseline characteristics in the propensity score-matched populations was evaluated based on standardized mean difference (SMD). With an absolute value of \u0026lt;\u0026thinsp;0.1, it was considered well-matched between the two cohorts. Kaplan\u0026ndash;Meier analysis and log-rank tests were used to evaluate the probability of the outcomes and the difference of the survival curves between the two cohorts. The adjusted hazard ratio (aHR) was calculated to evaluate the relative risks of different cranial nerve disorders based on the time-to-event analysis for both the HPV-vaccinated and control groups. We used Cox proportional hazards models to calculate the hazard ratio (HR) and the associated 95% confidence interval (95%CI). R\u0026apos;s Survival package v3.2\u0026ndash;3 was used to calculate HR, 95% CIs, and the test for proportionality. The two-sided p-value\u0026thinsp;\u0026lt;\u0026thinsp;0.05 was considered statistically significant.

We assessed differences in the risk of cranial nerve disorders across these subgroups during a year of follow-up following the index date. Finally, we also conducted a sensitivity test to compare the HPV vaccination and the influenza vaccination cohort with the same study design to verify the consistency of the results.\u003c/p\u003e\n\u003c/div\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eDATA AVAILABILITY\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eData is available from the TriNetX global network.

On the other hand, the HPV-vaccinated cohort had significantly higher risks of odor and taste disorders (aHR: 3.136, 95% CI: 0 2.562-3.840). Kaplan-Meier curves of different cranial nerve disorders also revealed significant probability disparities between the two cohorts (Log–Rank test, p \u0026lt; 0.001).\u003c/p\u003e\n\u003cp\u003eIn conclusion, for females between 9 and 26 years old, their HPV vaccination was associated with on one hand, lower risks of cranial nerve disorders, like hearing loss, vestibular function/other diseases of the inner ear, facial nerve disorders, and disorders of the trigeminal nerve, and on the other hand, higher risks on smell and taste disorders, as revealed over a year-long follow-up period.\u003c/p\u003e","manuscriptTitle":"Human papillomavirus vaccination poses different risks for various cranial nerve disorders - a retrospective cohort study using a real-world database","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-09-23 08:24:06","doi":"10.21203/rs.3.rs-4923637/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Reject after peer review","date":"2025-02-05T09:25:28+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"This content is not available.","date":"2025-01-01T16:35:51+00:00","index":2,"fulltext":"This content is not available."},{"type":"reviewerAgreed","content":"This content is not available.","date":"2024-12-30T18:25:28+00:00","index":2,"fulltext":"This content is not available."},{"type":"editorInvitedReview","content":"This content is not available.","date":"2024-10-11T09:49:58+00:00","index":1,"fulltext":"This content is not available."},{"type":"reviewerAgreed","content":"This content is not available.","date":"2024-09-25T19:24:58+00:00","index":1,"fulltext":"This content is not available."},{"type":"reviewersInvited","content":"","date":"2024-09-25T18:47:55+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-09-09T19:11:38+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-08-22T11:04:00+00:00","index":"","fulltext":""},{"type":"submitted","content":"npj Vaccines","date":"2024-08-16T08:28:53+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"npj-vaccines","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"npjvaccines","sideBox":"Learn more about [npj Vaccines](http://www.nature.com/npjvaccines/)","snPcode":"41541","submissionUrl":"https://submission.springernature.com/new-submission/41541/3?","title":"npj Vaccines","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"NPJ","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"a2544684-8bbf-47e1-8e2f-b24e780052ac","owner":[],"postedDate":"September 23rd, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[{"id":37347620,"name":"Health sciences/Health care/Public health/Epidemiology"},{"id":37347621,"name":"Health sciences/Medical research/Epidemiology"}],"tags":[],"updatedAt":"2025-02-26T10:53:37+00:00","versionOfRecord":[],"versionCreatedAt":"2024-09-23 08:24:06","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-4923637","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-4923637","identity":"rs-4923637","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
