Median Age at HPV Infection Among Women in the United States: A Model-Based Analysis Informed by Real-world Data.

ABSTRACT:

Background

The US Advisory Committee for Immunization Practices (ACIP) recommended shared clinical decision-making for human papillomavirus (HPV) vaccination of individuals aged 27 to 45 years (mid-adults) in June 2019. Determining the median age at causal HPV infection and CIN2+ diagnosis based on the natural history of HPV disease can help elucidate the incidence of HPV infections and the potential benefits of vaccination in mid-adults.

Methods

Real-world data on CIN2+ diagnosis from the prevaccine era were sourced from a statewide surveillance registry in Connecticut. Age distribution of CIN2+ diagnosis in 2008 and 2009 was estimated. A discrete event simulation model was developed to predict the age distribution of causal HPV infection. The optimal age distribution of causal HPV infection provided the best goodness-of-fit statistic to compare the predicted vs real-world age distribution of CIN2+ diagnosis.

Results

The median age at CIN2+ diagnosis from 2008 through 2009 in Connecticut was 28 years. The predicted median age at causal HPV infection was estimated to be 23.9 years. There was a difference of 5.2 years in the median age at acquisition of causal HPV infection and the median age at CIN2+ diagnosis.

Conclusions

Real-world data on CIN2+ diagnosis and model-based analysis indicate a substantial burden of infection and disease among women aged 27 years or older, which supports the ACIP recommendation to vaccinate some mid-adults. When natural history is known, this novel approach can also help determine the timing of causal infections for other commonly asymptomatic infectious diseases.

Project description:BackgroundReal-world performance of COVID-19 diagnostic tests under Emergency Use Authorization (EUA) must be assessed. We describe overall trends in the performance of serology tests in the context of real-world implementation.MethodsSix health systems estimated the odds of seropositivity and positive percent agreement (PPA) of serology test among people with confirmed SARS-CoV-2 infection by molecular test. In each dataset, we present the odds ratio and PPA, overall and by key clinical, demographic, and practice parameters.ResultsA total of 15,615 people were observed to have at least one serology test 14-90 days after a positive molecular test for SARS-CoV-2. We observed higher PPA in Hispanic (PPA range: 79-96%) compared to non-Hispanic (60-89%) patients; in those presenting with at least one COVID-19 related symptom (69-93%) as compared to no such symptoms (63-91%); and in inpatient (70-97%) and emergency department (93-99%) compared to outpatient (63-92%) settings across datasets. PPA was highest in those with diabetes (75-94%) and kidney disease (83-95%); and lowest in those with auto-immune conditions or who are immunocompromised (56-93%). The odds ratios (OR) for seropositivity were higher in Hispanics compared to non-Hispanics (OR range: 2.59-3.86), patients with diabetes (1.49-1.56), and obesity (1.63-2.23); and lower in those with immunocompromised or autoimmune conditions (0.25-0.70), as compared to those without those comorbidities. In a subset of three datasets with robust information on serology test name, seven tests were used, two of which were used in multiple settings and met the EUA requirement of PPA ≥87%. Tests performed similarly across datasets.ConclusionAlthough the EUA requirement was not consistently met, more investigation is needed to understand how serology and molecular tests are used, including indication and protocol fidelity. Improved data interoperability of test and clinical/demographic data are needed to enable rapid assessment of the real-world performance of in vitro diagnostic tests.

Project description:IntroductionLupus nephritis (LN) treatment aims to control and prevent flares and irreversible kidney damage. Around 30% of patients are unresponsive to treatment; however, real-world LN treatment patterns have not been reported. Objectives of this retrospective cohort study (GSK 209758) were to quantify the time to switching/re-initiating induction therapy in patients with LN initiating immunosuppressant therapy and conversion from induction to maintenance immunosuppressant therapy, and to assess corticosteroid use.MethodsPatients with LN initiating induction or maintenance immunosuppressant therapy were identified using claims data. Patients were followed up from the index date (immunosuppressant initiation date) until treatment discontinuation, death, disenrollment, administrative censoring, or the end of follow-up period. The cumulative incidence of switching/re-initiating induction therapy and conversion to maintenance therapy was estimated using outpatient pharmacy claims and procedure codes. Corticosteroid use was estimated using pharmacy claims; a mean daily dose of ≥ 7.5 mg/day was considered high.ResultsIn total, 5000 patients with LN contributed 5516 treatment episodes (induction cohort, N = 372; maintenance cohort, N = 5144). In the induction cohort, the cumulative incidence (95% confidence interval) of switching between induction therapies was 24.6% (20.1-30.0) at 12 months, while 59.6% (52.4-66.1) of patients converted to maintenance therapy at 12 months. In the maintenance cohort, 21.2% (19.9-22.5) re-initiated induction therapy at 12 months. Oral corticosteroid use decreased during the follow-up in both cohorts, but 21.5% of patients remained on a high dose at 12 months in the induction cohort, while 15.8% in the maintenance cohort were taking a high dose at 24 months.ConclusionsAround a quarter of patients with LN initiating immunosuppressant therapy switched within 12 months, while a fifth re-initiated induction therapy within 12 months. Use of high corticosteroid doses were observed during 24 months of follow-up. These data suggest that many patients do not respond to existing standard LN therapies.

Project description:IntroductionMyasthenia gravis (MG) is a rare, debilitating, chronic disorder caused by the production of pathogenic immunoglobulin G autoantibodies against the neuromuscular junction. A lack of real-world studies in rare diseases reflects a relatively limited understanding of the significant unmet needs and burden of disease for patients. We aimed to provide comprehensive real-world insights into the management and burden of MG from treating physicians in the United States (US).MethodsData were collected using the Adelphi Real World MG Disease Specific Programme™, a point-in-time survey of physicians and their patients with MG, in the US between March and July 2020. Physician-reported clinical data, including demographics, comorbidities, symptoms, disease history, treatments, and healthcare resource utilization, were collected.ResultsIn total, 456 patient record forms were completed by 78 physicians based in the US. At time of survey completion, patient mean age was 54.5 years. Mean time from symptom onset to diagnosis was 9.0 months (n = 357). Ocular symptoms were reported in 71.7% of patients. General fatigue affected 47.1% of patients and over half of those reported the severity as moderate or severe (59.5%, n = 128). Acetylcholinesterase inhibitors and/or steroids were the most frequently prescribed first-line treatment type among patients receiving treatment at time of survey completion and with moderate-to-severe symptoms (77.9%, n = 159/204). High-dose steroids (n = 14) and intravenous immunoglobulin (n = 13) were the most prescribed acute treatments among those receiving an acute treatment at time of survey completion (n = 36), with symptom exacerbations or myasthenic crises being the most common reasons for acute treatment. On average, 2.5 healthcare professionals were involved in patient management and 5.0 consultations were made per patient over the last 12 months.ConclusionsOur findings indicated that, despite treatment, there is a proportion of patients with MG in the US who had a significant need for improved disease management.
