BACKGROUND Herpes zoster affects a million people annually in the United States, while postherpetic neuralgia is the most common complication. Opioids is most prescribed as the first line medication for herpes zoster or postherpetic neuralgia, however it contributes to the increasing healthcare cost of treating herpes zoster and postherpetic neuralgia. With the advent of internet retailers providing alternative products for prevention and management these conditions, there are limited studies on the availability of products, the ingredients in the products, and consumer preference for the products. OBJECTIVE This study seeks to determine the availability of products for management of herpes zoster and postherpetic neuralgia and consumer preference based off ingredients. METHODS Internet retailer Amazon was used in September 2020 to conduct a search for products related to “shingles.” Top products sorted by reviews and ratings were determined to be either shingle specific (including “shingles” in either product title or description) or shingle non-specific. Analysis of price, rating, type of vehicle, and ingredients was performed. The types of vehicles, ingredients, and percentage of positive and negative reviews related to “shingles” of the product groups was analyzed with two-tailed two-sample proportions Z-test to assess a difference between shingles specific and shingles non-specific products. P<.05 showed statistical significance. RESULTS The top 131 products out of over 3,000 products was determined by having a rating of 4 or more after searching “shingles” on Amazon. 46 out of 131 products (35.1%) were shingles specific. Shingles non-specific products were more likely to have positive reviews mentioning “shingles” (P=0.005). As vehicles, balms (P=0.02) and salves (P=0.04) were more likely to be shingles specific and tablets or capsules (P=0.002) more likely to be shingles non-specific. Of ingredients analyzed, aloe vera was the top ranked ingredient, comprising 29 out of 131 total products (22.1%). Aloe vera (P=0.01), lemon balm (P=0.0009), vitamin E (P=0.03), and peppermint oil (P=0.008) were more likely included in shingles specific products, while magnesium (P=0.0096) was more likely included in shingles non-specific products. CONCLUSIONS There is an abundant amount of products and ingredients being used for management and treatment of shingles with certain ingredients preferred by customers. There is a discrepancy between approved ingredients and the ingredients preferred by customers. Furthermore, there are not enough studies on ingredients used by consumers on internet retailers, such as Amazon, and future studies can focus on the effectiveness of popular ingredients to decrease misinformation on the internet.

Background Herpes zoster affects approximately 1 million people annually in the United States, with postherpetic neuralgia as the most common complication. The frequent prescription of opioids as the first-line medication for herpes zoster or postherpetic neuralgia contributes to the increasing health care costs of their treatment. Despite the advent of internet retailers providing alternative products for the prevention and management these conditions, there are limited studies on the availability, ingredients, and consumer preference for the products. Objective This study used the internet retailer Amazon to determine the availability of products for the management of herpes zoster and postherpetic neuralgia, and assessed consumer preference based on listed ingredients. Methods The internet retailer Amazon was used to perform a search for products related to “shingles” in September 2020. Top products sorted by reviews and ratings were determined to be either shingles-specific (including “shingles” in either the product title or description) or shingles-nonspecific. Analysis of price, rating, type of vehicle, and ingredients was performed. The types of vehicles, ingredients, and percentages of positive and negative reviews related to “shingles” of the product groups were analyzed with a two-tailed two-sample proportions Z-test to assess the difference between shingles-specific and shingles-nonspecific products. Statistical significance was judged at P<.05. Results The top 131 products among over 3000 products retrieved were determined based on a rating of 4 or more stars after searching for the term “shingles” on Amazon. Forty-six of the 131 products (35.1%) were shingles-specific. Shingles-nonspecific products were more likely to have positive reviews mentioning “shingles” (P=.005). Vehicles, balms (P=.02), and salves (P=.04) were more likely to be shingles-specific, whereas tablets or capsules (P=.002) were more likely to be shingles-nonspecific. Among the ingredients analyzed, aloe vera was the top-ranked ingredient, included in 29 of the 131 total products (22.1%). Aloe vera (P=.01), lemon balm (P<.001), vitamin E (P=.03), and peppermint oil (P=.008) were more likely to be included in the shingles-specific products, whereas magnesium (P=.01) was more likely to be included in shingles-nonspecific products. Conclusions There is an abundance of products and ingredients being used for the management and treatment of shingles with certain ingredients preferred by consumers. There is a discrepancy between approved ingredients and the ingredients preferred by consumers. Furthermore, there are insufficient studies on ingredients used by consumers on internet retailers such as Amazon, and future studies can focus on the effectiveness of popular ingredients to decrease misinformation on the internet.

Herpes zoster can plague anyone who has had varicella or has received the varicella or chickenpox vaccine. The incidence of herpes zoster increases with age and rises exponentially after 60 years of age. Postherpetic neuralgia (PHN) may occur after herpes zoster at any age but typically occurs after 50 years of age, with over 40% of persons over 60 years of age suffering from PHN after a shingles attack. Up to 1 million new cases of herpes zoster and 200,000 new cases of PHN may now be anticipated in the United States every year, with the incidence rate increasing as the population grows and ages with prolonged life expectancies. Although new antiviral medications will improve and shorten the course of herpes zoster, they do not guarantee the prevention of PHN. Given the high prevalence of PHN in an aging population and the availability of primary prevention by vaccination, the objectives of this review are to describe the epidemiology, pathophysiology, and clinical manifestations of zoster and PHN and to recommend a combination of strategies for the clinical management and prevention of PHN.

7086 Background: The HRQOL of patients (pts) with chronic lymphocytic leukemia (CLL) has not been adequately delineated across patient, disease and treatment characteristics. We evaluated HRQOL of CLL pts undergoing treatment in the United States (US) by age, gender and line of therapy. Methods: Data were collected in Connect CLL, a prospective observational US registry. Physicians provided data on demographics, clinical characteristics and line of therapy at enrollment. HRQOL was self-reported by pts at enrollment using the Functional Assessment of Cancer Therapy-Leukemia, an instrument that yields a leukemia-specific total HRQOL score (FACT-Leu) and a cancer-specific total HRQOL score (FACT-G). Mean total scores were analyzed by line of therapy, age and gender. Statistical significance was ascertained by ANOVA using SAS 9.2. Multivariate analyses were conducted to assess the relative association of line of therapy, age and gender with HRQOL. Results: Among 1,252 pts enrolled from 161 geographically diverse centers (90% community, 8% academic, 2% veterans/military), pts were predominantly male (63%), white (89%) with mean age 69 yrs. Pts were categorized by line of therapy at enrollment: First 61%, Second 18%, Third 11%, Higher 9%; and by age group: <65 33%, 65-74 35%, 75+ 32%. Univariate analyses suggested that the total FACT-Leu score was significantly better in men than women (P=0.004); in pts aged 65-74 vs younger or older pts (P=0.033); and in pts initiating first-line treatment vs pts receiving subsequent treatments (P=0.0002). Similar results were found with the FACT-G score except that gender differences were not statistically significant. Multivariate analysis confirmed that line of therapy (P=0.007), gender (P<0.0001), and age group (P=0.039) were each associated with significant differences in the FACT-Leu total score. Conclusions: Results from the Connect CLL Registry indicate that HRQOL is better among pts initiating first-line therapy compared to pts initiating subsequent treatments, and that this remains true when age and gender are considered. Future analyses should determine how HRQOL may change over time relative to treatment and treatment response.

Abstract Background The incidence of herpes zoster (HZ) has been increasing in recent decades. Although 2 vaccines for HZ are available, there have been few studies on the incidence rates of HZ and postherpetic neuralgia (PHN) since their introduction. This study examined the incidence rates of HZ and PHN from 1994 to 2018 in the United States to determine if they have continued to increase since introduction of the HZ vaccines. Methods A de-identified longitudinal administrative claims database, the OptumLabs Data Warehouse, was used to assess incidence rates among individuals continuously enrolled in the database for ≥365 days with no prior history of HZ or PHN. Unstandardized and standardized incidence rates were calculated by year, 10-year age groups, sex, and race/ethnicity. Results There were 610 766 individuals with HZ (median age, 56.3; interquartile range, 43.0–68.7 years; 59.8% women; 70.6% white). From 1994 to 2018, the incidence of HZ increased from 286.0 (95% confidence interval [CI], 259.1–312.8) to 579.6 (95% CI, 554.2–605.0) cases per 100 000 person-years, an annual increase of 3.1% (95% CI, 2.5–3.6%). Since 2007, annual HZ incidence rates have decreased in individuals ≤20 and &gt;60 years old. The overall incidence rate of PHN was 57.5 (95% CI, 56.0–59.0) cases per 100 000 person-years. The proportion of individuals with HZ who developed PHN was higher from 2007 to 2018 than from 1994 to 2006. Conclusions HZ incidence rates have continued to increase in age groups for which HZ vaccines are not currently recommended, warranting a review of current vaccine recommendations.

Abstract Introduction: Generic formulations of imatinib were approved and commercially available in the United States starting in 2016, introducing vast cost savings to the standard treatment of chronic myeloid leukemia (CML). While bioequivalence studies of generic formulations are required for Food and Drug Administration approval, the safety of generic drug supply chains have come into question. There is limited real-world data comparing the effectiveness and safety profiles of generic formulations to the original. This study aimed to evaluate the effectiveness and safety of generic imatinib compared to the branded product. Methods: This retrospective study included patients treated at UNC Medical Centers who were diagnosed with CML and treated with imatinib at any time during their course of treatment. Data was retrieved from the institution's electronic health record and collected over the first 6 months of imatinib treatment to include both safety and effectiveness outcomes. The primary endpoint was to compare generic versus branded product effectiveness, as defined by the European LeukemiaNet (ELN) guidelines (achieving BCR-ABL/ABL ratio of &lt;10% and &lt;1% at 3 and 6 months, respectively). The secondary endpoints included comparisons of generic vs branded product safety, measured via patient adverse drug events (ADEs), all-cause hospitalizations, and early treatment discontinuation. Patients were excluded from primary endpoint evaluation and only included for safety endpoint analysis if they were not treated with imatinib first-line and if duration of imatinib treatment was less than 6 months. Results: Fifty-one CML patients met criteria with no significant differences in age or gender between the generic (n = 23) and brand (n = 28) imatinib groups (Table 1). First-line therapy was composed of 83% of patients on generic imatinib and 29% of patients on brand imatinib. Of those receiving first-line imatinib therapy, there was no difference in molecular responses at 3 and 6 months between generic and brand imatinib (p = 0.71). Brand imatinib was associated with numerically lower CML-related emergency department visits and hospitalizations when compared to generic imatinib, although this difference was not statistically significant (p = 0.12). Rates of discontinuation were numerically lower for brand imatinib although overall time to discontinuation was shorter for generic imatinib (Table 1). Conclusions: This study demonstrates real-world treatment effectiveness and safety of generic and brand imatinib in clinical practice. Generic imatinib appears to be associated with higher rates of CML-related ED visits and hospitalizations although sample size was small and statistical significance was not reached. Further analyses of comparisons and continuation of data collection will provide a more robust assessment to compare the effectiveness and safety of generic and brand imatinib in the real-world setting.

Introduction: Australia's largest state, Western Australia (WA), comprises a land area of more than 2.5 million square kilometres, an area than larger than that of Texas and Alaska in the United States combined, with a population of more than 2.6 million. Whilst a large proportion of Western Australians live in the capital city Perth, approximately 20% are dispersed across the state in regional and remote areas. The diagnosis and treatment of myeloma require specialist Haematologist management and frequent follow-up. Access to Haematology specialist services and treatment in WA is centred in metropolitan Perth, with outreach services visiting regional and remote areas limited in location and frequency. Some patients are required to travel long distances or relocate to access treatment. The aim of our study was to assess difference in clinical presentation, treatment and outcomes of myeloma patients living in regional or remote Western Australia compared to metropolitan Perth. Methods: A retrospective chart review of new cases of symptomatic multiple myeloma diagnosed between January 2008 and December 2019 and referred to Royal Perth Hospital and Fiona Stanley Hospital, two tertiary metropolitan hospitals was conducted. Data was obtained regarding patient demographics, disease characteristics, treatment, response and survival outcomes, through review of patient paper and electronic medical records. Patients were grouped into those living inside or outside the Perth metropolitan area (metro or non-metro) according to area codes obtained from the WA government data suite. Results: Two hundred and seventy-five cases were identified, 218 (79%) metro and 57 (21%) non-metro. Baseline characteristics for the two groups are listed in Table 1. The median age at diagnosis was 68.4 years (range 30-91.5 years) and 47% were female, with no significant difference between the groups. There were a higher number of patients with lytic bone disease at diagnosis in the non-metro cohort (75.4% non-metro vs 60.2% metro, p=0.03) as well as a higher proportion of patients with international staging system (ISS) stage II or III disease (77.8% non-metro vs 55.8% metro, p=0.005). Sixty three percent of patients overall received first line bortezomib based therapy and 27% first line imid based therapy, with no significant difference by location. Overall 41% of patients underwent autologous stem cell transplantation, 70% of those ≤70 years of age, with no significant difference between the groups (33.3% non-metro vs 42.5% metro, p=0.21). The median overall survival (OS) was 47 months for the entire cohort. Survival was lower in the non-metro cohort, although this did not reach statistical significance (median OS 52 months for metro vs 40 months for non-metro, p=0.05) Figure 1. Progression free survival (PFS) was similar between the two groups (median PFS 23 months metro vs 12 months non-metro, p=0.12) Figure 2. Early mortality at 6 and 12 months was higher in the non-metro cohort (Six-month mortality was 21.1% non-metro vs 8.3% metro, p=0.01. Twelve-month mortality was 28.1% non-metro vs 13.4% metro, p=0.01) Figure 3. There was a trend in cause of early mortality due to infection being higher in the metro cohort, and cause of early mortality due to renal failure being higher in the non-metro cohort, Table 1. Conclusions: In our cohort, patients living in non-metropolitan locations were more likely to present with higher ISS stage and lytic lesions at diagnosis. Rates of early mortality were significantly higher in the non-metropolitan cohort. There was a trend towards shorter overall survival although this did not meet statistical significance. These differences may represent delays in clinical presentation and diagnostic workup and highlight the need for optimisation of follow up of patients in non-metropolitan areas particularly during the early time period post diagnosis. Periods of resource constraint and travel restrictions as is faced currently may accentuate these disparities. In addition, the nature of myeloma therapy is evolving with addition of treatments requiring expertise to deliver, such as monoclonal antibodies and chimeric antigen receptor T cells. As these therapies become commercial further studies are needed to assess adequacy of access for patients from non-metropolitan centres.

Background: Epinephrine is the first-line therapy for patients with anaphylaxis, and intramuscular (IM) delivery is shownto be superior to subcutaneous (SC) delivery. There currently is no consensus on the ideal body position for epinephrine autoinjector (EAI) administration.Objective: We designed this study to investigate whether SC tissue depth (SCTD) is affected by body position (e.g., standing, sitting, supine), which can potentially impact delivery of EAI into the IM space.Methods: Volunteer adults (ages >/= 18 years) from a military medical treatment facility in the United States were recruitedto participate in this study. SCTD of the vastus lateralis was measured via ultrasound at standing, sitting, and supine bodypositions. Subjects’ age, sex, and body mass index (BMI) were collected. Statistical analysis was performed to compare averageSCTD between body positions, sex, and BMI.Results: An analysis of variance of 51 participants (33 men and 18 women) did not reveal statistically significant differencein SCTD among standing, sitting, and supine body positions. It did show a significantly greater SCTD in women than in men (2.72 +/- 1.36 cm versus 1.10 +/- 0.38 cm; p < 0.001). There was no significant association observed between BMI and SCTD in this study.Conclusion: Body position did not seem to significantly change the distance between skin and thigh muscle in adults. Thiswould suggest that there might not be an ideal body position for EAI administration. Therefore, in case of anaphylaxis, promptadministration of epinephrine is recommended at any position.
