ABSTRACT IMPACT: Long-acting insulin containing protamine is more likely to be associated with skin depigmentation. OBJECTIVES/GOALS: An acquired disorder, skin depigmentation was found to be significantly correlated with diabetes. While a recent meta-analysis pointed at a possible similar pathogenesis, the possibility of vitiligo occurring as a drug-induced disease was never explored. This study aimed at elucidating whether utilization of specific insulins may play a role. METHODS/STUDY POPULATION: Records from the Medical Panels Expenditure Survey (MEPS) database made available by the Agency for Healthcare Research and Quality were used to identify all injectable insulin users (n=8867). ICD-9/10 codes were abstracted from the medical conditions files for all the subjects reporting any type of injectable insulin use (1996-2017). Skin depigmentation codes identified in our dataset were 709 and L81. Insulins were categorized based on duration of action, short-acting (SA), intermediate-acting (IA), and long-acting (LA), as well as based on formulation ingredients (zinc, protamine-zinc, other), and insulin combination (SA with or without IA/LA containing or not protamine-zinc). The association between skin depigmentation occurrence and insulin type and/or category was assessed by Fisher’s exact test. RESULTS/ANTICIPATED RESULTS: A total of 225 out of 8867 individuals were diagnosed with skin depigmentation. Incidence of skin depigmentation was 2.25% in SA users (n1=3606, p=0.355), 2.24% in LA users (n2=3910, p=0.337), and 2.39% in IA users (n3=4015, p=0.062). Occurrence of skin depigmentation was similar between users of insulin mono- or combo therapy (p=0.758). Interestingly, among IA insulins, insulin protamine-zinc insulin (n4=3992) distinguished as being mainly responsible for the association with the occurrence of skin depigmentation (p=0.062), whereas insulin zinc was not (n5=37, p=1.000). The highest skin depigmentation incidence was observed among Pacific Islanders (2.66%, p=0.110). Males distinguished by a skin depigmentation incidence of 2.34% vs. 1.91% in females (p=0.086). DISCUSSION/SIGNIFICANCE OF FINDINGS: We report that presence of protamine-zinc may play a role in the development of skin depigmentation. It is uncertain whether this risk may be shared equally by insulin users diagnosed with type 1 and type 2 diabetes. Of note, we observed a higher skin depigmentation incidence than that reported by community- (0.2%) or hospital-based (1.8%) studies.

ABSTRACT IMPACT: Younger patients receiving biologics for rheumatoid arthritis have higher medical expenditure. OBJECTIVES/GOALS: TNF inhibiting biologic disease modifying antirheumatic drugs are among the most highly regarded treatment options for rheumatoid arthritis (RA). We aimed at evaluating the medical and prescription costs associated with monoclonal antibody use vs. other RA treatment options in subjects diagnosed with RA. METHODS/STUDY POPULATION: Records from the Medical Panels Expenditure Survey (MEPS) database made available by the Agency for Healthcare Research and Quality were used to identify all RA subjects (n=_____). Demographics and MEPS-provided flags for RA were abstracted from the medical condition files for all the subjects surveyed (2008-2018). Prescribed biologics were identified based on generic and brand names following a manual review to detect any misspellings. Total medical expenses and prescription expenses were abstracted for all identified RA subjects. Subject were surveyed for two consecutive years, thus expenses were assessed for each of the two surveyed years. Costs were adjusted for inflation and expressed in 2018 dollars. The relationship between biologics use, cost and age or gender was evaluated by Fisher’s exact test. RESULTS/ANTICIPATED RESULTS: Most RA subjects did not use biologics. RA was more prevalent in women than in men with no significant correlation between sex and the use of biologics in year 1, year 2, or the combined years (p=.44, p=.63, and p=.65, respectively). Biologics users were found to be significantly younger (p<.001), with a mean of 52.8 years compared to 59 years in those who did not use biologics. The 95% confidence interval was 3.7 to 8.6 years younger than non-users. Total medical and prescription costs were higher for biologics users (p<.001) in all analyses. The mean prescription cost difference was $24,038 more per year for biologics users, and $26,296 more total medical expenses, CI $20,502-$27,230 and CI $21,947-$30,646, respectively. There was a trend for biologics users to have higher non-prescription medical expenses (p=.05). DISCUSSION/SIGNIFICANCE OF FINDINGS: Interestingly, biologics non-users had some extreme outliers with expenses far higher than any biologics users, possibly due to poorly controlled RA due to age and/or comorbidities. Yet, our most interesting findings are the higher use of biologics among younger RA subjects and the elevated costs of care being driven mainly by prescriptions cost.

ABSTRACT IMPACT: Despite their clinical benefits reported in patients with Parkinson’s, statin use is not associated with cost savings. OBJECTIVES/GOALS: Statins have unique lipid-lowering, anti-inflammatory and anti-oxidant benefits. Their pleiotropic benefits were shown to decrease risk of occurrene and progression of Parkinson’s disease (PD). In this study we explored whether or not statin use reflects medical or prescription cost savings. METHODS/STUDY POPULATION: Records from the Medical Panels Expenditure Survey (MEPS) database made available by the Agency for Healthcare Research and Quality were used to identify all PD subjects (n=613). Demographics and PD ICD9/10 codes, 332/G20, were abstracted from the medical condition files for all the subjects (1996-2018). Prescribed cholesterol drugs were identified based on generic and brand names following a manual review to detect any misspellings. Total medical expenses and prescription expenses were abstracted for all identified PD subjects. Subject were surveyed for two consecutive years, thus expenses were assessed for each of the two surveyed years. Costs were adjusted for inflation and expressed in 2018 dollars. The relationship between cholesterol drug use, cost and age or gender was evaluated by Fisher’s exact test. RESULTS/ANTICIPATED RESULTS: Out of the 613 PD subjects identified, 421 received no cholesterol management, 15 received non-statins, 153 received a statin and 24 received a statin-based combo therapy. While the medical expenses in the general population receiving a statin are roughly three times higher than non-statin users, no significant cost difference was noticed between PD subjects receiving or not statins. However, after adjusting for age and gender, receiving statin vs. non-statin vs combo vs none was significantly associated with total expense (p=0.017) suggesting that cholesterol management decision may play a significant role. DISCUSSION/SIGNIFICANCE OF FINDINGS: Selection of specific cholesterol treatment may play a considerable role in the overall PD expenditure. Duration of statin treatment and type of statin are expected to play a role.

ABSTRACT IMPACT: Melatonin use could alleviate virus-induced respiratory illnesses. OBJECTIVES/GOALS: Melatonin was identified as a potential repurposable drug in the fight against SARS Cov-2. Its ability to attenuate some virus inoculation effects raises the question whether melatonin use could alleviate virus-induced respiratory illness. Here we evaluated the occurrence of respiratory conditions in melatonin users and non-users surveyed. METHODS/STUDY POPULATION: Records from the Medical Panels Expenditure Survey (MEPS) database made available by the Agency for Healthcare Research and Quality were used to evaluate whether melatonin may be associated with reduced viral respiratory disease burden. First, all subjects reporting melatonin use (1996-2017) were collected along with records for all subjects reporting respiratory diseases as identified by consolidated ICD-9/10 codes. Second, all diagnosis codes were retrieved for all individuals identified in the first step. In total there were 201,490 occurrences of the specified conditions among 180,468 unique individuals. The relative risk of specific respiratory disease occurrence was computed for melatonin users and non-users. Population estimates for melatonin use were also determined. RESULTS/ANTICIPATED RESULTS: Among 221 melatonin users, 132 had at least one respiratory illness. Among the 180,468 total subjects reporting at least one respiratory condition, melatonin use was associated with a lower rate of the common cold, pharyngitis, strep throat, scarlet fever, and sinusitis. Furthermore, melatonin was associated with a significantly reduced risk of common cold (RR 0.760, CI 0.587-0.985) and sinusitis (RR 0.407, CI 0.186-0.890). Due to low subject counts, the reduced risk observed for scarlet fever and strep throat was not considered significant. Melatonin users had a higher relative risk of allergic rhinitis (RR 1.393, CI 1.043-1.862) and asthma (RR 2.166, CI 1.672-2.806), probably due to melatonin active prescribing in these patients as sleep aid. DISCUSSION/SIGNIFICANCE OF FINDINGS: Although melatonin showed a lower relative risk of certain viral respiratory conditions, the low melatonin user numbers and their heterogeneous distribution over the time interval led to highly variable population estimates. Yet, our data suggests that melatonin may alleviate viral respiratory illness and deserves further investigation.
