The association between BNT162b2 vaccinations and incidence of immune-mediated comorbidities. Vaccine 2024:S0264-410X(24)00536-X. [PMID: 38729910 DOI: 10.1016/j.vaccine.2024.04.097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Revised: 04/28/2024] [Accepted: 04/30/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND A large vaccination campaign was initiated worldwide in December 2020 in order to prevent infection with SARS-CoV-2 and severe Covid-19 disease. However, long-term adverse effects of vaccination remain unclear. Therefore, our objective was to examine the association between vaccination and the incidence of autoimmune diagnoses in the first year after vaccine uptake. METHODS This retrospective cohort study based on Clalit Health Services (CHS) comprehensive database compared the rates of immune-mediated diagnoses among BNT162b2 vaccinated versus unvaccinated individuals. As a reference, a secondary cohort compared individuals infected with Sars-CoV-2 versus uninfected individuals. The minimum follow-up period was 4 months. The cohorts were divided into 4 age groups (12-17, 18-44, 45-64, 65 years or older). Multivariate Cox proportional hazard regression models were applied, followed by a correction for multiple comparisons using the False Discovery Rate (FDR) method, hence accounting for the investigation of multiple clinical outcomes. RESULTS Increased risk for immune-mediated diagnoses following vaccination with BNT162b2 was observed for psoriasis in all age groups (HR 1.41-1.69), colitis among patients younger than 65 years (HR 1.38-1.93), vitiligo in patients aged 45-64 (HR 2.82, 95 %CI: 1.57-5.08) and for polymyalgia-rheumatica in patients aged 65 years or older (HR 2.12, 95 % CI: 1.3-3.47). In the reference cohort, patients who were infected by Covid-19 were at increased risk for fibromyalgia (HR 1.72, 95 % CI: 1.36-2.19 in individuals aged 18-44; HR 1.71, 95 % CI: 1.31-2.22 in individuals aged 45-64), and hypothyroidism (HR 1.54, 95 % CI: 1.15-2.07 in individuals aged 65 years or older). CONCLUSIONS The BNT162b2 vaccine was associated with increased risk (though rare) for psoriasis, colitis and polymyalgia rheumatica. These findings should be considered as a part of the risk-benefit assessment when planning future vaccination programs for various population groups.

COVID-19 Vaccine Effectiveness among Patients with Psoriatic Disease: A Population-Based Study. Vaccines (Basel) 2024; 12:453. [PMID: 38793704 PMCID: PMC11125670 DOI: 10.3390/vaccines12050453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 04/19/2024] [Accepted: 04/22/2024] [Indexed: 05/26/2024] Open
Abstract
Limited information is available on the effectiveness of COVID-19 vaccination in patients with psoriasis and psoriatic arthritis (psoriatic disease (PsD)). The objective of our research was to assess the effectiveness of mRNA COVID-19 vaccination in preventing SARS-CoV-2 positivity and severe infection in a cohort of patients with PsD and the association of immunosuppressants on SARS-CoV-2 infection-related outcomes from December 2020 to December 2021. Vaccine effectiveness was assessed in a matched nested case control study using conditional logistic regression adjusted for demographics, comorbidities and immunosuppressant use. Study outcomes included SARS-CoV-2 positivity and severe COVID-19 (moderate-to-severe COVID-19-related hospitalizations or death). At least one dose of mRNA COVID-19 vaccine was associated with reduced risk of SARS-CoV-2 positivity and severe COVID-19 (OR = 0.41 (95% CI, 0.38-0.43) and OR = 0.15 (95% CI, 0.11-0.20), respectively). A more significant effect was found among patients who received three vaccines doses compared with those who did not receive any (OR (for positive SARS-CoV-2) = 0.13 (95% CI, 0.12-0.15) and OR (for severe disease) = 0.02 (0.01-0.05)). Etanercept and methotrexate were associated with higher risk of SARS-CoV-2 positivity (1.58 (1.19-2.10), p = 0.001 and 1.25 (1.03-1.51), p = 0.03, respectively). In conclusion, our results show that mRNA COVID-19 vaccines are effective in reducing both infection and severe COVID-19-related outcomes.

The risk factors for uveitis among psoriatic arthritis patients: a population-based cohort study. Clin Rheumatol 2024; 43:1053-1061. [PMID: 38082206 DOI: 10.1007/s10067-023-06834-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 11/09/2023] [Accepted: 11/26/2023] [Indexed: 02/20/2024]
Abstract
OBJECTIVE To assess the frequency of uveitis in patients with psoriatic arthritis (PsA) in the era of biologics and to identify risk factors associated with uveitis. METHODS A retrospective matched cohort study was conducted within the database of a large healthcare provider. Newly diagnosed 6147 adult PsA patients between 2005 and 2020 were matched by the index date of PsA diagnosis, age, sex, and ethnicity to 23,999 randomly selected controls. This cohort was used to examine the association between PsA and uveitis. An additional analysis was conducted within the PsA group to identify uveitis risk factors, using two analytic approaches: a retrospective cohort study and a nested case-control study. RESULTS Uveitis was diagnosed in 107 patients in the PsA group (1.7%) vs 187 (0.8%) patients in the control group (adjusted HR, 2.38, 95% CI 1.80-3.15, p<0.005) and was similar when the analysis was confined to patients without past uveitis. Uveitis was diagnosed more in females (2.1% vs 1.3%, HR 1.61, 95% CI 1.09-2.40, p<0.05), and was acute in all cases. Anterior uveitis was documented in 41.1% of the cases, 64.5% unilateral, and 9.3% bilateral. In the PsA group, using nested case control approach, only past uveitis [adjusted OR 136.4 (95% CI 27.38-679.88), p<0.005] and treatment with etanercept [adjusted OR 2.57 (95% CI 1.45-4.57), p=0.001] were independently associated with uveitis. Only one PsA patient with uveitis (out of 107) required systemic oral treatment with prednisone, while the rest of the patients were treated with topical glucocorticosteroids only. CONCLUSION PsA is associated with increased risk of uveitis. Past uveitis and treatment with etanercept were associated with higher risk of uveitis. Key Points • Psoriatic arthritis (PsA) is a major risk factor for uveitis with hazard ratio of 2.38 compared to healthy individuals without PsA. • Among PsA patients, the past event of uveitis and treatment with etanercept are risk factors for uveitis. • Uveitis in patients treated with biologics for their PsA requires topical therapy only in most of the cases.

The Risk of Herpes Zoster Events in Patients with Spondyloarthritis and the Effect of BNT162b2 mRNA COVID-19 Vaccine. Vaccines (Basel) 2024; 12:85. [PMID: 38250898 PMCID: PMC10821079 DOI: 10.3390/vaccines12010085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 01/07/2024] [Accepted: 01/10/2024] [Indexed: 01/23/2024] Open
Abstract
The data on the risk of herpes zoster (HZ) in spondyloarthropathy (SpA) patients are sparse, especially regarding its association with the novel mRNA COVID-19 vaccines and immunosuppressants. We aimed to evaluate whether SpA diagnosis and/or immunosuppressant use affect HZ risk and the influence of mRNA COVID-19 vaccination. We assessed the association between SpA (psoriatic arthritis (PsA) and ankylosing spondylitis (AS)) diagnoses and HZ in a large population database with patients matched by age and sex to controls. We also assessed the association between the COVID-19 vaccine and new-onset HZ using two nested case-control studies, identifying all new HZ cases diagnosed from 1 January-31 December 2021 within the SpA and general population cohorts, matched randomly by sex, age and HZ index date to controls without HZ. Exposure to mRNA COVID-19 vaccination was ascertained in the 6 weeks prior to the index date both in cases and controls. In our results, the incidence rate of HZ was higher in PsA patients vs. the general population, at 1.03 vs. 0.64 per 100 person-years, respectively (adjusted HR = 1.55; 95%CI, 1.19-2.02). Within the SpA group, Jak-I treatment was associated with a higher risk of developing new-onset HZ (adjusted OR = 3.79; 1.15-12.5). Multivariable conditional logistic regression models we used showed no association between COVID-19 vaccination and new-onset HZ among the SpA patients (OR = 1.46; 0.68-3.14).

Treatment Persistence of Apremilast Among Patients with Psoriatic Arthritis. Biologics 2023; 17:129-136. [PMID: 37814674 PMCID: PMC10560465 DOI: 10.2147/btt.s425693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 09/27/2023] [Indexed: 10/11/2023]
Abstract
Introduction Persistence in drug therapy reflects treatment effectiveness and tolerability. We aim to estimate the persistence of apremilast prescribed to patients with psoriatic arthritis (PsA) and to identify characteristics associated with treatment discontinuation in a real-world setting. Methods Patients with PsA treated with apremilast from January 2016 were identified from a large health database and followed until medication stop date (using 3-months grace period), death or the end of observation period (June 2021). Demographic data, Charlson comorbidity index and concomitant and previous use of conventional and biologic DMARDs were extracted. The reasons for drug discontinuation were manually retrieved from patient charts. Time to discontinuation was estimated using survival analysis using Kaplan-Meier functions. Results Overall, 568 PsA patients treated with apremilast were identified. The mean age was 55.3±14.0 years, of whom 332 (58.5%) were females, 38.4% were obese (BMI>30), 75.2% had a Charlson comorbidity index>1, 24.1% were on concomitant treatment with methotrexate and 72.4% were biologic naïve. The median persistent period was 6.1,95% CI (5.2-6.9) months in which only 16.9% remained persistent on apremilast. No difference was found with regard to age, sex, socioeconomic status, ethnicity and obesity between patients who were persistent compared to patients who discontinued apremilast. Concomitant treatment with methotrexate and prior history of biologic therapy did not affect drug persistency (log rank P=0.957 and 0.082, respectively). Causes for treatment discontinuation were due to lack of skin efficacy in 19.4%, lack of joint efficacy in 33.3%, combined skin and joint inefficacy at 2.3% and due to side effects in 24.1%. Conclusion In this large observational retrospective cohort of patients treated with apremilast, a relatively low drug persistence was observed with 6-month and 1-year survival rates of 50.3% and 31.3%, respectively. Treatment discontinuation was mainly due to joint inefficacy, advocating for more studies for proper patient selection to assure treatment effectiveness and persistency.

Estimating the economic burden of long-Covid: the additive cost of healthcare utilisation among COVID-19 recoverees in Israel. BMJ Glob Health 2023; 8:e012588. [PMID: 37463787 PMCID: PMC10357303 DOI: 10.1136/bmjgh-2023-012588] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Accepted: 06/25/2023] [Indexed: 07/20/2023] Open
Abstract
INTRODUCTION Postacute sequelae resulting from SARS-CoV-2 infections (LONG-COVID) have been reported. The resulting added economic burden from the perspective of healthcare organisations is not clear. Therefore, this study aims to evaluate the additive healthcare costs among COVID-19 recoverees, in a large community-dwelling general population, as incurred by an insurer-provider organisation over time. METHODS In this historical cohort study, cost data from Clalit Health Services (CHS) were analysed. The primary endpoint was the direct cost incurred by CHS per month per person. Costs were measured for COVID-19 recoverees and matched controls, from January 2019 to January 2022. Difference in differences (DiDs) were calculated as the difference in mean monthly costs in cases and controls in the post-COVID-19 individual period, deducing their cost difference in a prepandemic 12 months baseline period. RESULTS Among N=642 868 community-dwelling COVID-19 recoverees, 268 948 (40.8%) were 0-19 years old and 63 051 (9.6%) were 60 years or older. A total of 16 017 (2.5%) of recoverees had been hospitalised during the acute phase of the COVID-19 disease. Costs in cases and controls converged after 16 months from recovery. The mean monthly cost incurred by CHS per COVID-19 recoverees over up to 15 months (mean: 8.25) of post-COVID-19 follow-up was higher by 8.2% (US$8.2) compared with matched controls. The excess cost attributable to post-COVID-19 effects (DID) was 7.6% of the cost in controls (US$7.7 per patient per month). Both net and relative DIDs were substantially higher in patients who required hospitalisation during the acute phase of COVID-19 and in older adults. Excess in hospitalisations, primary care physicians and medical specialists' visits-related costs were observed. CONCLUSIONS Long-term effects of SARS-CoV-2 infections translate into excess healthcare costs, months after recovery, hence requiring adjustments of funds allocation. These excess costs gradually diminish after recoveree, returning to baseline differences 16 months after recoveree.

Factors Associated with Using Telemedicine in the Primary Care Clinics during the COVID-19 Pandemic in Israel. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13207. [PMID: 36293788 PMCID: PMC9603207 DOI: 10.3390/ijerph192013207] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 10/02/2022] [Accepted: 10/09/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND The COVID-19 pandemic generated an extraordinary need for telemedicine. OBJECTIVE To identify the factors and multi-way interactions associated with telemedicine use in primary healthcare during the COVID-19 pandemic. METHODS This population-based study included all members (2,722,773) aged ≥18 years of the largest healthcare organization in Israel who used primary care clinic services between 1 March 2020 and 31 December 2021. Individuals were classified as telemedicine users (≥1 phone/video visits or asynchronous encounters) or non-telemedicine users (only in-person encounter/s). RESULTS Ethnicity was the most discriminative variable associated with telemedicine use, with 85% and 52% users among Jews and Arabs, respectively. Higher odds for telemedicine utilization were observed among women, residents of urban areas, those confined to home, individuals with high level of technology literacy, residents of the central area (in Jews only), young Jews, and older Arabs. Based on decision tree analysis, the segments of the population with the lowest telemedicine use were characterized by lower primary care needs and comorbidities, as well as low technology literacy. The proportion of telemedicine use in these groups was 56% and 27% in Jews and in Arabs, respectively. CONCLUSION A proactive intervention program should be applied among populations who are less likely to use telemedicine in the primary care clinics, including Arabs, Jews who live in the distant periphery, and individuals with low technology literacy.

Vitamin D deficiency is associated with higher risks for SARS-CoV-2 infection and COVID-19 severity: a retrospective case-control study. Intern Emerg Med 2022; 17:1053-1063. [PMID: 35000118 PMCID: PMC8742718 DOI: 10.1007/s11739-021-02902-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 11/20/2021] [Indexed: 12/30/2022]
Abstract
Robust evidence of whether vitamin D deficiency is associated with COVID-19 infection and its severity is still lacking. The aim of the study was to evaluate the association between vitamin D levels and the risks of SARS-CoV-2 infection and severe disease in those infected. A retrospective study was carried out among members of Clalit Health Services (CHS), the largest healthcare organization in Israel, between March 1 and October 31, 2020. We created two matched case-control groups of individuals for which vitamin D levels and body mass index (BMI) were available before the pandemic: group (A), in which 41,757 individuals with positive SARS-CoV-2 PCR tests were matched with 417,570 control individuals without evidence of infection, and group (B), in which 2533 patients hospitalized in severe condition for COVID-19 were matched with 2533 patients who were tested positive for SARS-CoV-2, but were not hospitalized. Conditional logistic models were fitted in each of the groups to assess the association between vitamin D levels and outcome. An inverse correlation was demonstrated between the level of vitamin D and the risks of SARS-CoV-2 infection and of severe disease in those infected. Patients with very low vitamin D levels (< 30 nmol/L) had the highest risks for SARS-CoV-2 infection and also for severe COVID-19 when infected-OR 1.246 [95% CI 1.210-1.304] and 1.513 [95% CI 1.230-1.861], respectively. In this large observational population study, we show a significant association between vitamin D deficiency and the risks of SARS-CoV-2 infection and of severe disease in those infected.

Abstract
Purpose To evaluate the total biopsy and positive biopsy rates in women at high risk of breast cancer compared to the general population. Methods The study group consisted of 330 women with pathogenic variants (PVs) in BRCA1/2 attending the dedicated multidisciplinary breast cancer clinic of a tertiary medical center in Israel. Clinical, genetic, and biopsy data were retrieved from the central healthcare database and the medical files. Patients aged 50 years or older during follow-up were matched 1:10 to women in the general population referred for routine breast cancer screening at the same age, as recommended by international guidelines. The groups were compared for rate of biopsy studies performed and percentage of positive biopsy results. Matched analysis was performed to correct for confounders. Results The total biopsy rate per 1000 follow-up years was 61.7 in the study group and 22.7 in the control group (p < 0.001). The corresponding positive biopsy rates per 1000 follow-up years were 26.4 and 2.0 (p < 0.001), and the positive biopsy percentages, 42.9% and 8.7% (p < 0.0001). Conclusion Women aged 50 + years with PVs in BRCA1/2 attending a dedicated clinic have a 2.7 times higher biopsy rate per 1000 follow-up years, a 13.2 times higher positive biopsy rate per 1000 follow-up years, and a 4.9 times higher positive biopsy percentage than same-aged women in the general population.

Abstract
BACKGROUND Although the risk of cardiovascular disease has been discussed extensively in both psoriasis (PsO) and psoriatic arthritis (PsA), very few studies have addressed the occurrence of venous thromboembolic (VTE) events among PsO patients, and even fewer in PsA. Thus, our goal was to assess the association between PsA and VTE events using a large population-based database. METHODS This retrospective cohort study includes all 5,275 patients with newly diagnosed PsA from the largest health care provider in Israel between January 2003 and December 2018. Identified PsA patients were matched by age, sex, ethnicity, and index date with 21,011 controls without PsA from the same database. Both groups were followed through June 30, 2019 for the occurrence of VTE event. Cox proportional hazard regression models were used to assess the association between PsA and VTE. RESULTS PsA cohort consisted of 53.2% females with mean age of 51.7±15.4 Sixty-two patients (1.2%) were diagnosed with VTE in the PsA group and 176 patients (0.8%) in the control group (p=0.023, HR=1.40, 95% CI 1.05-1.87). However, there was no increased risk of VTE among PsA patients on multivariable analysis (p=0.16, HR=1.27, 95% CI 0.91-1.80). Within the PsA group, patients with VTE were more often of older age and with history of VTE. CONCLUSIONS This study suggests that the increased risk of VTE in PsA patients appears to be related to the underlying comorbidities and not independently associated with PsA. Age and previous history of VTE were the only risk factors associated with increased risk of VTE in patients with PsA. Addressing VTE risk is recommended especially in the era of Janus kinase inhibitors.

Abstract
Background Until coronavirus disease 2019 (COVID-19) drugs specifically developed to treat COVID-19 become more widely accessible, it is crucial to identify whether existing medications have a protective effect against severe disease. Toward this objective, we conducted a large population study in Clalit Health Services (CHS), the largest healthcare provider in Israel, insuring over 4.7 million members. Methods Two case-control matched cohorts were assembled to assess which medications, acquired in the last month, decreased the risk of COVID-19 hospitalization. Case patients were adults aged 18 to 95 hospitalized for COVID-19. In the first cohort, five control patients, from the general population, were matched to each case (n=6202); in the second cohort, two non-hospitalized SARS-CoV-2 positive control patients were matched to each case (n=6919). The outcome measures for a medication were: odds ratio (OR) for hospitalization, 95% confidence interval (CI), and the p-value, using Fisher's exact test. False discovery rate was used to adjust for multiple testing. Results Medications associated with most significantly reduced odds for COVID-19 hospitalization include: ubiquinone (OR=0.185, 95% CI [0.058 to 0.458], p<0.001), ezetimibe (OR=0.488, 95% CI [0.377 to 0.622], p<0.001), rosuvastatin (OR=0.673, 95% CI [0.596 to 0.758], p<0.001), flecainide (OR=0.301, 95% CI [0.118 to 0.641], p<0.001), and vitamin D (OR=0.869, 95% CI [0.792 to 0.954], p<0.003). Remarkably, acquisition of artificial tears, eye care wipes, and several ophthalmological products were also associated with decreased risk for hospitalization. Conclusions Ubiquinone, ezetimibe, and rosuvastatin, all related to the cholesterol synthesis pathway were associated with reduced hospitalization risk. These findings point to a promising protective effect which should be further investigated in controlled, prospective studies.

Abstract
OBJECTIVE To examine the association between psoriatic arthritis (PsA) and all-cause mortality from a large population-based database. METHODS Patients with PsA from the Clalit Health Services database were identified between 2003-2018 and matched to 4 controls by age, sex, ethnicity, and index date. Patient demographics, comorbidities, and treatments were extracted. Mortality data were obtained from the Israeli Notification of Death certificate. The proportionate mortality rate (PMR) of the leading causes of death was calculated and compared to that of the general population. Cox proportional hazard regression models were used to estimate the crude and the multivariate adjusted HR for the association between PsA and all-cause mortality and for factors associated with mortality within the PsA group. RESULTS There were 5275 patients with PsA and 21,011 controls included and followed for 7.2 ± 4.4 years. The mean age was 51.7 ± 15.4 years, and 53% were females. Among patients with PsA, 38.2% were on biologics. Four hundred seventy-one (8.9%) patients died in the PsA group compared to 1668 (7.9%) in the control group. The crude HR for the association of PsA and all-cause mortality was 1.16 (95% CI 1.04-1.29) and 1.02 (95% CI 0.90-1.15) on multivariate analysis. Malignancy was the leading cause of death (26%), followed by ischemic heart disease (15.8%); this is in keeping with the leading causes of death in the general population. Older age, male sex, lower socioeconomic status, increased BMI, increased Charlson comorbidity index scores, and history of psoriasis or hospitalization in 1 year prior to entry were positive predictors for mortality. CONCLUSION No clinically relevant increase in mortality rate was observed in patients with PsA, and specific PMRs were similar to those of the general population.

Abstract
Background:Data on the association between PsA and mortality remains conflicting as it has been hampered by small sample size with few events and the potential for confounders of selection and severity biases from clinic-based studies.Objectives:To examine the association between PsA and all-cause mortality in a cohort of PsA patients and matched controls, using data from a population-based large medical record database.Methods:Patients with newly diagnosis of PsA between January 1st, 2003 and December 31st, 2018 from the Clalit Health database were identified. 4 controls without PsA were selected and matched to cases of PsA by age (within 1 year), sex, ethnicity (Jewish vs. non-Jewish), and index date. The two groups were followed from the index date until the first occurrence of death from any cause or end of follow-up (June 30, 2019). Data on mortality and on the immediate cause of death was based on the Notification of Death form legally required by the Israeli Ministry of the Interior for every deceased person in the country. Demographic data including age, sex, ethnicity (Jewish or Arab), and socioeconomic status (SES) at inception were retrieved from the CHS database. Data regarding tobacco use (ever), obesity, body mass index, diabetes mellitus, hyperlipidemia, hypertension, ischemic heart disease, prior cerebrovascular accident, congestive heart failure, chronic renal failure, chronic obstructive pulmonary disease, cirrhosis, prior malignancy, psoriasis, and the concomitant use of glucocorticosteroids, conventional and biologic disease-modifying anti-rheumatic drugs (cDMARDs and bDMARDs, respectively) were extracted from the database.We estimated the attributable fraction of the various causes of death in PsA patients and compared it to the proportionate mortality rate (PMR) of the leading causes of death in Israel during 2014-2016 based on a recently published report by the Central Bureau of Statistics. Cox proportional hazard regression models were used to estimate the crude and the multivariate adjusted hazard ratio (HR) for the association between PsA and all-cause mortality, as well as for factors associated with mortality within the PsA group.Results:A total of 5275 PsA patients were identified between 2003 and 2018 and where matched to 21,011 controls based on age, sex, and ethnicity. The mean age was 51.7 ± 15.4 years of whom 53% were females. More individuals in the PsA group were smokers, obese, with diabetes, hypertension, and dyslipidemia, as well as with a history of ischemic heart disease, cerebrovascular disease, congestive heart failure, chronic obstructive pulmonary disease, chronic renal failure and cirrhosis than patients in the control group, and 38.2% of PsA patients were on b-DMARDS. Overall 471 (8.9%) patients died in the PsA group compared to 1,668 (7.9%) in the control group during a mean follow-up of 7.2 ± 4.4 years. The crude HR for the association of PsA and all-cause mortality was 1.16 (95% CI, 1.042-1.29). However, the association was not significant on multivariate analysis with HR of 1.096 (95% CI, 0.977-1.229).In PsA patients, malignancy was the leading cause of death, constituting 26% of all deaths, followed by ischemic heart disease 15.8%, diabetes 6.2%, cerebrovascular diseases 5.5% and septicemia 5.5%, in keeping with the order of the leading causes of death in the general population of Israel during 2014-2016 as recently reported by the Central Bureau of Statistics.On multivariate model Cox regression analysis, male sex, increased body mass index, increased Charlson comorbidity index scores and history of hospitalization in a year prior to death were associated with higher mortality, whereas treatment bDMARDs and cDMARDs were associated with a lower relative risk of death.Conclusion:No clinically relevant increase in mortality rate was observed in PsA patients from the period 2003-2018. The most common causes of specific proportionate mortality rates in our cohort were similar to those in the general population.Disclosure of Interests:None declared

Abstract
Background:Psoriatic arthritis (PsA) is a chronic, immune-mediated, systemic inflammatory arthritis associated with comorbidities including metabolic syndrome, cardiovascular risk factors and cardiovascular disease (CVD).Objectives:To evaluate the prevalence of venous thromboembolism (VTE) in a PsA patient cohort using a large health care provider database.Methods:A large health care provider database serving 4.7 million healthcare subscribers was interrogated for an adult patient cohort who were newly diagnosed with PsA between January 2005 (start date) and 31 December 2018 with date of diagnosis considered the index date. A risk set was employed to randomly select 4 controls without PsA as a comparator group to the PsA cohort matched by age, sex, ethnic group, and index date. Both groups were followed from the index date until the first occurrence of VTE event, death, or end of follow-up 31 December 2019, whichever came first. Marginal model with robust covariant estimate counting for the matching was used to estimate the crude and adjusted hazard ratio (HR) for the association between PsA and VTE. Within the group of PSA patients, Cox proportional hazard regression models was used to calculate the risk of having VTE given demographic variables, SES, smoking, selected comorbidities, and conventional vs biologic disease modifying anti-rheumatic drugs (c/bDMARD). Continuous variables were summarized with mean ± standard deviation, and categorical variables were presented as numbers and proportions. All tests were 2-sided; p values of < = 0.05 were considered statistically significant. All data were analyzed using SPSS, 24 (IBM SPSS Statistics for Windows, version 24.0, 2016, Armonk, NY) and SAS, 9.4 (SAS institute Inc, Cary, NC).Results:The PsA cohort consisted of 5,275 patients, 53.2% females with mean age of 51.66 ±15.41. The control group consisted of 21,011 subjects matched for age and sex. In relation to the control group, the PsA cohort had a higher SES (25.1% vs 23.4%, p<0.0001), higher tobacco use (42.2% vs.39.6% p<0.0001) and obesity (33.5% vs 25.8%, p<0.0001). The study group had a statistically significant higher incidence of diabetes (33.8% vs 26.2%, p<0.0001), IHD (10.3% vs 8.6%, p<0.0001), CHF (2.2% vs 1.6%, p=0.004), hypertension (30.1% vs 26.2%, p<0.0001), CVA/TIA (4.6% vs 3.9%, p=0.024) and vascular disease (3.7% vs 3.0%, p=0.005). There were 62 patients (1.2%) diagnosed with VTE in the PsA group as opposed to 176 patients (0.8%) in the control group (p=0.023, HR=1.397, CI 1.05-1.87). The mean age of patients diagnosed with VTE was higher in the PsA group relative to controls (64.90± 13.20 vs 51.54 ± 15.41, respectively, p<0.0001), with higher age, BMI>30, cancer, IHD, vascular disease, and previous VTE found to be associated with VTE in the PsA group relative to controls in both univariate and multivariate analyses. The higher prevalence of VTE in PsA patients relative to controls did not remain statistically significant in multivariate analysis following adjustment for risk factors. Within the PsA group, patients with VTE were more often of older age and with past history of VTE. Both cDMARD and bDMARD were not associated with increased risk of VTE among PsA patients.Conclusion:The prevalence of VTE was higher in PsA group compared to the general population, but after adjustment for comorbidities and risk factors, it no longer remained statistically significant. Among PsA patients, age and previous history of VTE were associated with increased risk of VTE. Addressing VTE risk in the management of patients with PsA is recommended especially in the era of Janus kinase inhibitors.Disclosure of Interests:None declared

Dose-dependent association of proton pump inhibitors use with gastric intestinal metaplasia among Helicobacter pylori-positive patients. United European Gastroenterol J 2021; 9:343-353. [PMID: 32962566 PMCID: PMC8259238 DOI: 10.1177/2050640620951403] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 07/23/2020] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Gastric intestinal metaplasia is a pre-cancerous condition associated with multiple factors. OBJECTIVE We evaluated whether cumulative proton pump inhibitor dose is associated with the diagnosis of gastric intestinal metaplasia while controlling for multiple variables. METHODS We retrospectively identified patients who underwent upper endoscopy with gastric biopsy between 2005 and 2014. Covariate data retrieved included age, sex, ethnicity, smoking status, Helicobacter pylori status (based on clarithromycin-amoxicillin-proton pump inhibitor issued), cumulative proton pump inhibitor issued within 10 years (quartiles [PPI-Q1-4 ] of daily drug dose), anti-parietal cell antibodies, body mass index and comorbidity index. RESULTS Of the 14,147 included patients (median age 63.4 years; women 54.4%; Helicobacter pylori-positive 29.0%), 1244 (8.8%) had gastric intestinal metaplasia. Increasing age, Helicobacter pylori infection, smoking, anti-parietal cell antibodies and proton pump inhibitor use were all associated with the diagnosis of gastric intestinal metaplasia. Upper quartiles of cumulative proton pump inhibitor doses (PPI-Q4 and PPI-Q3 vs. PPI-Q1 ) were associated with the diagnosis of gastric intestinal metaplasia: adjusted odds ratios 1.32 (95% confidence interval [CI] 1.111.57) and 1.27 (95% CI 1.07-1.52), respectively, for the whole cohort (Ptotal 0.007, Ptrend 0.013), 1.69 (95% CI 1.23-2.33) and 1.40 (95% CI 1.04-1.89), respectively, for Helicobacter pylori-positive patients (Ptotal 0.004, Ptrend 0.005) and 1.21 (95% CI 0.98-1.49) and 1.20 (95% CI 0.96-1.49), respectively, for Helicobacter pylori-negative patients (Ptotal 0.288, Ptrend 0.018). Upper quartiles of proton pump inhibitor dose were associated with a 5-10-fold increased risk of low-grade dysplasia. CONCLUSIONS Among Helicobacter pylori-positive patients, proton pump inhibitor use appears to be associated with a dose-dependent increased likelihood of gastric intestinal metaplasia.

Abstract
BACKGROUND Until COVID-19 drugs specifically developed to treat COVID-19 become more widely accessible, it is crucial to identify whether existing medications have a protective effect against severe disease. Towards this objective, we conducted a large population study in Clalit Health Services (CHS), the largest healthcare provider in Israel, insuring over 4.7 million members. METHODS Two case-control matched cohorts were assembled to assess which medications, acquired in the last month, decreased the risk of COVID-19 hospitalization. Case patients were adults aged 18-95 hospitalized for COVID-19. In the first cohort, five control patients, from the general population, were matched to each case (n=6202); in the second cohort, two non-hospitalized SARS-CoV-2 positive control patients were matched to each case (n=6919). The outcome measures for a medication were: odds ratio (OR) for hospitalization, 95% confidence interval (CI), and the p-value, using Fisher's exact test. False discovery rate was used to adjust for multiple testing. RESULTS Medications associated with most significantly reduced odds for COVID-19 hospitalization include: ubiquinone (OR=0.185, 95% CI (0.058 to 0.458), p<0.001), ezetimibe (OR=0.488, 95% CI ((0.377 to 0.622)), p<0.001), rosuvastatin (OR=0.673, 95% CI (0.596 to 0.758), p<0.001), flecainide (OR=0.301, 95% CI (0.118 to 0.641), p<0.001), and vitamin D (OR=0.869, 95% CI (0.792 to 0.954), p<0.003). Remarkably, acquisition of artificial tears, eye care wipes, and several ophthalmological products were also associated with decreased risk for hospitalization. CONCLUSIONS Ubiquinone, ezetimibe and rosuvastatin, all related to the cholesterol synthesis pathway were associated with reduced hospitalization risk. These findings point to a promising protective effect which should be further investigated in controlled, prospective studies.

Treatment persistence of biologics among patients with psoriatic arthritis. Arthritis Res Ther 2021; 23:44. [PMID: 33514410 PMCID: PMC7845003 DOI: 10.1186/s13075-021-02417-x] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 01/04/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Persistence of biologic therapy in psoriatic arthritis (PsA) patients is an important factor in individualized patient treatment planning and healthcare policy and guideline development. OBJECTIVE To estimate the persistence of biologic agents prescribed to PsA patients in a real-life setting as well as factors associated with improved biologic drug survival in these patients. METHODS Patients with PsA from a large healthcare provider database with at least two consecutive dispensed prescriptions of a biologic agent indicated for PsA from January 1, 2002, until December 31, 2018, were identified and followed until medication stop date or the end of observation period. Patients were considered non-persistent whenever a permissible lag time of 6 months from the time of prescription issuance until medication filling date was exceeded. Treatment changes were based on physician decisions and patient preferences. Demographic data including age, sex, body mass index (BMI), ethnicity, smoking history, and socioeconomic status as well as Charlson comorbidity index were retrieved. Data regarding use of steroids and conventional disease-modifying anti-rheumatic drugs (cDMARDs) were also extracted. Descriptive statistics, including means (standard deviations) for continuous variables and frequencies (%) for categorical variables, were used. Persistence estimates were derived using non-parametric survival analysis using Kaplan-Meier functions, with treatment discontinuations as failure events. Cox regression hazard ratio models were conducted to investigate factors associated with drug persistence. RESULTS A total of 2301 PsA patients with 2958 treatment periods were identified and included in the analyses. Mean age of the study population was 50.9 ± 14 years, 54% were females, 70.4% were with BMI > 25, 40% were current smokers, and 76% were with a Charlson comorbidity index > 1. The most commonly prescribed drug was etanercept (33%), followed by adalimumab (29%), golimumab (12%), secukinumab (10%), ustekinumab (8%), and infliximab (8%). While approximately 40% of patients persisted on therapy following 20 months of treatment, only about 20% of patients remained on any particular biologic agent after 5 years. Analyzing the data for all treatment periods while taking into account all lines of therapy revealed that secukinumab had a higher persistency than adalimumab, infliximab, and ustekinumab, with a log rank of 0.022, 0.047, and 0.001, respectively. Female sex and smoking were associated with lower drug persistence (HR = 1.25, 95% CI = 1.13-1.38 and HR = 1.109, 95% CI = 1.01-1.21, respectively). On analyzing the data using only the first indicated biologic line, no superiority of any single anti-tumor necrosis factor-alpha (anti-TNFα) agent was observed, while secukinumab was found to be superior as second line therapy to adalimumab, etanercept, infliximab, and ustekinumab but not to golimumab with a log rank P value of 0.001, 0.004, 0.025, and 0.002, respectively. CONCLUSIONS In this large observational cohort studied in the era of biologic therapy, a relatively low drug persistence was observed, with female sex and smoking having a negative impact on persistency. None of the anti-TNFα agents was found to be more persistent than others as first line therapy, while secukinumab was found to be superior to other biologics when indicated as second line of therapy.

Impact of flash glucose monitoring on glucose control and hospitalization in type 1 diabetes: A nationwide cohort study. Diabetes Metab Res Rev 2021; 37:e3355. [PMID: 32469094 DOI: 10.1002/dmrr.3355] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 04/21/2020] [Accepted: 05/12/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND We evaluated the impact of flash continuous glucose monitoring (FCGM) on glycemic control and healthcare burden in a large real-world cohort of patients with type 1 diabetes (T1D) initiating FCGM technology. METHODS In this retrospective cohort study, we included adults (age ≥18 years) with T1D from a large Health Maintenance Organization in Israel, who initiated FCGM during 2018. Primary outcomes included change in HbA1c ≥3 months following FCGM commencement and change in rate of internal-medicine hospitalization. Additional outcomes included changes in glucose test strip purchases, diabetes related outpatient health care visits and hospitalization for diabetic ketoacidosis (DKA) and/or severe hypoglycemia. RESULTS The study included 3490 patients, followed for a median of 14 (inter-quartile range 11-15) months after FCGM commencement. Among 2682 patients with an HbA1c measured both at baseline and ≥3 months after FCGM initiation, average HbA1c declined from 8.1% ± 1.46% to 7.9% ± 1.31% (P < .001) at first measurement and was maintained during follow up. Specifically, in those with HbA1c ≥8%, a mean decline of 0.5% (P < .001) was observed. A clinically significant HbA1c reduction of ≥0.5% was experienced by 25.5% of the patients. The rate of internal medicine hospitalization, visits to primary care, or visits to endocrine/diabetes specialists in the period following FCGM commencement vs the 6 months prior was significantly reduced (P < .001). Hospitalization for DKA and/or hypoglycemia declined as well (P = .004). CONCLUSIONS FCGM was associated with significant and durable improvement in glycemic control as well as reduced consumption of healthcare services.

Abstract
OBJECTIVE The need for personalization of the reference values of thyroid function tests has been previously suggested. We aimed at determining TSH reference values in a large cohort of children according to age, sex, BMI, and ethnicity. DESIGN A population-based cohort study. METHODS The study cohort included 75 549 healthy children aged 5-18 years. Data analyzed included age, gender, TSH, FT4 levels, BMI and ethnicity. Multivariate logistic regression analysis examined the associations between the study parameters. RESULTS TSH in the Jewish population is lower than in the non-Jewish population (median: 2.1 IU/L (IQR: 1.5) vs 2.2 IU/L (IQR: 1.5), P < 0.0001). TSH is significantly affected by BMI for children defined as underweight, normal weight, overweight or obese, levels increased as weight diverged from the normal range (median levels: 2.1 IU/L (IQR: 1.4), 2.0 IU/L (IQR: 1.3), 2.1 IU/L (IQR: 1.4), 2.4 (IQR: 1.5), respectively, P < 0.001). The 2.5 percentile is affected by gender and BMI (P < 0.02 and P < 0.001, respectively), while the 97.5 percentile is affected by ethnic origin and BMI (P < 0.001 for both). New TSH reference intervals (RI) adjusted according to BMI and ethnicity are suggested. Comparison of the old and new RI demonstrate the significance of RI personalization: 25.1% of the children with TSH levels above the old RI are within the new RI, while 2.3% of the children who were in the old RI are below the new RI. CONCLUSIONS TSH reference values in children are affected by BMI and ethnicity. Reference values should be individualized accordingly to improve future clinical decision-making and treatment.

Abstract
Background:Persistence in biologic therapy in psoriatic arthritis is critical to optimize symptom remission, functional capacity and health care costs.Objectives:To estimate the persistence to biologic treatment prescribed to PsA patients in a real-life setting as well as factors associated with improved biologic drug survival in these patients.Methods:Patients with PsA from a large health care provider database with at least two consecutive dispensed prescriptions of a biologic agent indicated for PsA from January 1st, 2002 until December 31st, 2018 were identified and followed until medication stop date or the end of observation period. Patients were considered non-persistent whenever a new prescription was dispensed and a permissible gap of 6 months was exceeded prior to starting on this biologic agent from the prescription date. Treatment changes were based on physician decisions and patient preferences.Demographic data including age, sex, BMI, ethnicity, smoking history and socioeconomic status as well as Charlson comorbidity index were retrieved. Data regarding use of steroids and non-biologic disease-modifying anti-rheumatic drugs were also extracted. Descriptive statistics, including means (standard deviations) for continuous variables and frequencies (%) for categorical variables, were used. Persistence estimates were derived using non-parametric survival analysis using Kaplan-Meier functions, with treatment discontinuations as failure events. Cox regression hazard ratio models were conducted to investigate factors associated with drug persistence.Results:2301 PsA patients with 2958 treatment periods were identified and included in the analyses. The mean age was 50.9±14 years of whom 54% were females, 70.4% of the study population had a BMI>25, and 36% were obese(BMI>30), 40% were current smokers, and 76% had a Charlson comorbidity index higher than 1. The most commonly prescribed drug was etanercept, followed by adalimumab, golimumab, secukinumab, ustekinumab and infliximab at 33%, 29%, 12%, 10%,8% and 8%, respectively. Only about 20% of patients remained on a particular biologic agent after 5 years, whereas about 40% persisted on therapy following 20 months of treatment. A Kaplan-Mayer survival analysis with pairwise comparisons of all treatment choices with respect to lines of therapy was conducted. When analyzing the data for all treatment periods and taking into account all lines of therapy, secukinumab had a higher persistency than adalimumab, infliximab and ustekinumab, with a Log Rank of 0.022, 0.047 and 0.001, respectively, as is shown in figure 1. Female sex and smoking were associated with lower drug persistence (HR=1.25, 95%CI 1.13-1.38 and HR=1.109, 95%CI 1.01-1.21, respectively). When analyzing the data regarding second-line biologic agents, secukinumab was found to be superior to adalimumab, etanercept, infliximab and ustekinumab but not to golimumab with a Log-Rank P value of 0.001, 0.004, 0.025 and 0.002, respectively (figure 2). On analyzing the data using only the first indicated biologic line, no superiority of any single anti-Tumor Necrosis Factor-alpha (anti-TNFα) agent was observed.Conclusion:In this large observational cohort, in the era of biologic therapy, a relatively low persistence was observed, with female sex and smoking having a negative impact on persistency. None of the anti-TNFα agents as first line therapy was found to be more persistent than others, while secukinumab was found to be superior to other biologics when indicated as second line of therapy.References:NoneFigure 1.Figure 2.Acknowledgments:noneDisclosure of Interests:None declared

Abstract
OBJECTIVE To assess the prevalence of systemic lupus erythematosus (SLE) in a psoriatic arthritis (PsA) cohort and to compare it to the general population using the database of a large healthcare provider. METHODS We analyzed the database of a PsA cohort (2002-2017), matched for age and sex, with randomly selected controls for demographics, clinical and laboratory manifestations, and dispensed medications. Statistical analysis used t test and chi-square test as appropriate. In the PsA group, incidence density sampling was performed matching PsA patients without SLE as controls to each case of PsA with SLE by age and follow-up time. Univariable and multivariable conditional logistic regression analyses were used to assess factors affecting SLE development. RESULTS The PsA and control groups consisted of 4836 and 24,180 subjects, respectively, with a median age of 56 ± 15 years, and of whom 53.8% were female. Eighteen patients (0.37%) in the PsA group and 36 patients (0.15%) in the control group were diagnosed with SLE (P = 0.001). SLE patients without PsA had higher anti-dsDNA and anticardiolipin antibodies. The usage of drugs with known potential to induce SLE was higher in the PsA than in the control group. Older age at PsA diagnosis, shorter PsA duration, and statin treatment were associated with SLE in PsA patients. CONCLUSION A 2.3-fold increase in the prevalence of SLE in PsA relative to the control group was found. Risk factors for SLE development included older age at PsA diagnosis, shorter PsA duration, and statin treatment. The association between PsA and SLE may affect treatment choices and medication development.

Abstract
BACKGROUND Drug survival rates in patients with psoriasis had been described extensively. Different survival rates of TNF-α inhibitors (TNFIs), ustekinumab and secukinumab were reported. OBJECTIVES To investigate drug survival rates of TNFIs, ustekinumab and secukinumab, with particular emphasis on the difference between ustekinumab and secukinumab. METHODS Survival analysis was performed in patients with moderate-to-severe psoriasis who received adalimumab, infliximab, etanercept, ustekinumab and secukinumab treatment in 2002-2018, using the Clalit Health Services database. Stratified analysis was performed according to biologic treatment lines. Multivariate analysis was performed adjusting for demographic variables, calendar year, metabolic syndrome, psoriatic arthritis, biologic treatment line, biologic naivety, co-administration of oral treatments and previous oral systemic treatment exposure. RESULTS Among 1459 patients treated with 3070 biologic medication courses, ustekinumab had a significantly higher crude survival as compared with TNFIs and secukinumab. The mean drug survival of ustekinumab, adalimumab, etanercept, infliximab and secukinumab was 43.5 (CI: 39.7-47.2), 38.2 (CI: 34.8-41), 33.9 (CI: 30.8-37.1), 28.2 (CI: 22.5-33.8) and 17.1 (CI: 15.6-18.6) months, respectively, with significant statistical differences for all comparisons (P < 0.001). The differences between ustekinumab and secukinumab were not significant following adjustment to factors that included treatment line (hazard rate 1.16, CI: 0.93-1.43). CONCLUSION Different drug survival rates between ustekinumab and secukinumab are determined by the treatment line and calendar year, reflecting the availability of biologic medications, and not only by the biologic attributes of each medication.

Abstract
6591 Background: Observational studies have shown an increased risk of BC with use of HRT. However, data on the prognosis of BC that develop in HRT users are inconsistent. The association between HRT use and results of the 21-gene Recurrence Score (RS) assay (Oncotype DX, Genomic Health Inc.) has not been investigated. We aimed to analyze this association, and examine the actual rate of distant recurrence or death in this population. Methods: Clalit Health Services (CHS) is the largest health maintenance organization (HMO) in Israel. We identified all CHS newly diagnosed ER+, N- breast-cancer patients, aged 45-60 that performed a RS assay between 01/2006-12/2012 and that were treated for at least three months with HRT during the eight years before BC diagnosis. A 1:4 matched-cohort analysis was performed, with matching made according to age and year of BC diagnosis. Clinical and demographic data were extracted from the CHS centralized registry for all patients. RS assay scores was grouped according to the TAILORX categorization and distribution was compared using Chi-square test. Kaplan-Meier analysis with log-rank test was performed in order to compare time to a combined outcome of distant-recurrence and mortality. Results: A cohort of 259 HRT-treated patients was identified and matched with 1001 controls, not treated with HRT. The proportions of low-risk patients (RS 0-25) and high-risk patients (RS 26-100) were 76.8% and 23.2%, respectively, within HRT-treated patients, and 80.4% and 19.6% within controls. Chi square test was not found significant (χ2= 1.634, p = 0.201). The mean follow-up time was 148.4 months for the cases and 146.9 months for controls, with log-rank test not showing a significant difference between groups. Conclusions: These data did not show significant association between HRT use and higher RS assay scores, and also did not find an association between HRT use and actual distant recurrence or death. Although the proportion of patients with high risk RS appeared to be slightly higher within HRT treated patients, this difference had not reached significance and further studies are required.

Cardiac and cardiovascular morbidities in patients with psoriatic arthritis: a population-based case control study. Clin Rheumatol 2019; 38:2069-2075. [PMID: 30937638 DOI: 10.1007/s10067-019-04528-y] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 03/16/2019] [Accepted: 03/20/2019] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To assess the prevalence of risk factors associated with cardiovascular disease (CVD) and CVD-related morbidity in a large Middle-Eastern psoriatic arthritis (PsA) cohort. METHOD A retrospective case control study was conducted using Israel's largest health care provider's patient database from 2000 to 2013. For each patient with PsA, 10 patients with no history of psoriasis or arthritis were matched for age and sex. Analysis of CVD-related risk factors and morbidity included hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus type 2 (DM-2), obesity, smoking, ischemic heart disease (IHD), congestive heart failure (CHF), cerebrovascular accident (CVA), carotid artery disease, peripheral vascular disease (PVD), aortic aneurism, valvular heart disease (VHD), and cardiomyopathy. Statistical analysis was conducted using t test and chi-square tests as appropriate. Univariate and multivariable logistic regression models assessed the association between PsA and CVD-related risk factors and morbidity. RESULTS Three thousand one hundred sixty-one PsA patients were included, with average age 58 ± 15.0 years, of whom 53.4% were women. Increased prevalence of DM-2, HLD, HTN, and obesity (OR 1.7, 1.5, 1.5, 1.5 respectively) was noted in the PsA group. Increased prevalence of IHD (p < 0.0001), PVD (p < 0.0001), CHF (p = 0.002), VHD (p < 0.0001), and cardiomyopathy (p = 0.006) was found in the PsA group compared to the control group even after adjusting for CVD risk factors. CONCLUSIONS A high prevalence of CVD-related risk factors and morbidity was found in this Middle Eastern PsA population, in accordance with data from other geographic regions. These results emphasize the importance of clinician awareness of the increased risk for CVD-related complications in PsA patients.

Abstract
INTRODUCTION Calcium channels play a significant role in the regulation of cell proliferation and apoptosis. This study investigates associations between calcium channel blocker (CCB) use and the incidence of prostate cancer (PCa). METHODS A nested case-control study was conducted using the Clalit Health Services database. We formed a population-based cohort of patients who were prescribed their first antihypertensive agent between 2000 and 2014. For each newly diagnosed PCa case in the cohort, 10 controls were matched by age, calendar year of cohort entry, and duration of follow-up. Multivariate conditional logistic regression analyses were used to evaluate the odds ratios (ORs) of PCa among CCB users compared with users of other antihypertensive drugs. RESULTS We identified 4346 patients with newly diagnosed PCa during the median follow-up of 5.3 years. The exposure to CCBs was associated with a slight increase in risk for PCa (OR 1.10, 95% confidence interval [CI] 1.02-1.18) when compared with non-CCB antihypertensive drugs. In secondary analyses, evidence was found of a duration-response relationship, with the association for PCa increasing by 27% for every 10-year increment of CCB use (OR 1.27, 95% CI 1.04-1.56). CONCLUSIONS The results of this large population-based study indicate a modest but significant increase in the risk of PCa among CCB users, and the risk increases with duration of use.

Abstract
Background: It has been suggested that calcium channel blockers (CCBs) may increase the risk of lung cancer; however, current evidence is conflicting and limited. Objective: Investigate the associations between CCB use and lung cancer. Methods: We conducted a population-based nested case-control study. A cohort was formed of patients prescribed their first antihypertensive agent from 2000 to 2014. CCB exposure information was obtained by identification of all prescriptions dispensed during study follow-up. Cases were patients newly diagnosed with lung cancer during follow-up. Each case was matched with 10 controls by age, sex, calendar year of cohort entry, and duration of follow-up. Multivariate conditional logistic regression was used to estimate odds ratios (ORs) with 95% CIs of lung cancer associated with ever use of CCBs. Results: During a median follow-up of 6.2 years, we identified 4174 cases of lung cancer. Ever use of CCBs was associated with an increased risk of lung cancer (adjusted OR = 1.13; 95% CI = 1.06-1.21), when compared with the use of other antihypertensive drugs. A duration-response relation was observed, with the ORs gradually increasing with longer cumulative duration of CCB use (<5 years: OR = 1.12, 95% CI = 1.04-1.20; 5-10 years: OR = 1.22, 95% CI = 1.07-1.40; >10 years: OR = 1.33, 95% CI = 0.90-1.96; P trend < 0.001). Conclusion and Relevance: The results of this large population-based study indicate that the use of CCBs is associated with a modest but significant increase in the risk of lung cancer. This association appeared to increase with longer duration of use.

Abstract
BACKGROUND Cancer risk following long-term exposure to systemic immunomodulatory therapies in patients with psoriasis is possible. OBJECTIVES To assess a dose-response relationship between cumulative length of exposure to biological therapy and risk of cancer. METHODS Four national studies (a healthcare database from Israel, and prospective cohorts form Italy, Spain and the U.K. and Republic of Ireland) collaborating through Psonet (European Registry of Psoriasis) participated in these nested case-control studies, including nearly 60 000 person-years of observation. 'Cases' were patients who developed an incident cancer. Patients with previous cancers and benign or in situ tumours were excluded. Four cancer-free controls were matched to each case on year of birth, sex, geographic area and registration year. Follow-up for controls was censored at the date of cancer diagnosis for the matched case. Conditional logistic regression was performed by each registry. Results were pooled using random-effects meta-analysis. RESULTS A total of 728 cases and 2671 controls were identified. After matching, differences between cases and controls were present for the Charlson Comorbidity Index in all three registries, and in the prevalence of previous exposure to psoralen-ultraviolet A and smoking (the British Association of Dermatologists Biologic Interventions Register only). The risk of first cancers was not significantly associated with cumulative exposure to biologics (adjusted odds ratio per year of exposure 1·02, 95% confidence interval 0·92-1·13). Results were similar if squamous and basal cell carcinomas were included in the outcome. CONCLUSIONS Cumulative length of exposure to biological therapies in patients with psoriasis in real-world clinical practice does not appear to be linked to a higher risk of cancer after several years of use.

Abstract
INTRODUCTION It is uncertain whether subclinical hypothyroidism should be treated with levothyroxine, particularly in the elderly. This study evaluated the association between levothyroxine treatment and mortality in individuals 65years or older with subclinical hypothyroidism and TSH values <10mIU/L. METHODS A case-control study in which patients 65years or older with TSH levels of 4.2-10mIU/L who died in the years 2012-2016 ('cases') were compared with matched individuals who did not die during this period ('controls'). Matching was based on gender, age, Charlson comorbidity index, date of TSH testing, duration of follow-up and TSH quartile. All cases of known thyroid disease or cases in which anti-thyroid medications or glucocorticoids were dispensed in the year preceding the TSH evaluation were excluded. Use of levothyroxine was compared between groups. RESULTS During the follow-up period, 419 individuals died and these were matched with 1558 individuals who did not. Factors found to be associated with mortality were age, senile dementia, congestive heart failure, chronic renal failure and a history of cerebrovascular disease. On multivariate analysis, treatment with levothyroxine was associated with significantly increased mortality (HR=1.19 CI 1.03-1.38). Femoral fractures and atrial fibrillation following initiation of levothyroxine therapy were not more prevalent in individuals who died during the follow-up period. CONCLUSIONS Treatment with levothyroxine is associated with significantly increased mortality in individuals 65years or older with subclinical hypothyroidism and TSH<10.

Abstract
BACKGROUND There is limited information on the epidemiology of psoriatic arthritis (PsA) in general and in Middle Eastern populations in particular. The aims of this study were to estimate the prevalence and incidence rates of PsA and their temporal trends in the general population in Israel. METHODS In this study, a cohort of adult patients with PsA was derived from the database of Clalit Health Services (CHS), Israel's largest health fund, with over 4.4 million members. The crude and age- and sex-standardized prevalence and incidence rates of PsA from 2006 to 2015 in the general population were calculated. The variation in PsA prevalence was assessed in relation to several demographic factors. RESULTS Among the 2,931,199 individuals aged 18 years and older registered in the CHS database in 2015, 4490 patients had a diagnosis of PsA (322 incident cases), resulting in overall crude prevalence and incidence rates of 0.153% (95% CI 0.149%, 0.158%) and 10.9 (95% CI 9.8, 12.3) per 100,000 population, respectively. The reported prevalence of PsA in Israel has doubled between 2006 and 2015 (from 0.073% to 0.153%). In contrast, the global incidence rate remained stable, with a gradual increase in incidence among individuals aged 51 to 70 years. PsA is associated with Jewish ethnicity, high socioeconomic status, and higher body mass index. CONCLUSIONS The prevalence and incidence of PsA in Israel are within the range of previous estimates from Southern European populations. An increase in the reported prevalence of PsA was observed over the past decade in the general population in Israel.

Abstract
e12512 Background: Tumors with HER2 overexpression usually respond to HER2-targeted therapies. Since the CLEOPATRA and EMILIA trials, a taxane plus trastuzumab and pertuzumab (TTP) are the first-line standard for the management of HER2 + metastatic breast cancer (MBC) and trastuzumab emtansine (TDM-1) is the second-line standard. Intrinsic subtypes existing within HER2+ tumors may impact the degree of a patient’s response to anti HER2 therapy; however HER2 subtyping for predicting response is still experimental and not in routine clinical use. In this retrospective population-based study, we aimed to assess whether duration of treatment (DOT) of second-line TDM1 is associated with the DOT of first-line TTP, and might serve as a hint for a HER2 subtype. Methods: Clalit Health Services (CHS) manages health care of 52% of the Israeli population. We identified 113 HER2+ CHS MBC patients, treated with TTP as first-line treatment that initiated TDM1 as second-line, until Dec. 31, 2016. Patient's (pts) demography, HER2 and HR status were recorded. A Cox proportional hazard model, stratified by HR status, adjusted for age and prior adjuvant trastuzumab, was used to explore the association between second-line and first-line DOT in HR positive and negative pts. Results: Pts baseline characteristics and DOT in first- and second-line treatment are presented in the table. A statistically significant association between DOT of both treatment lines was found in HR positive pts with a trend also in HR negative pts. Conclusions: The observed association between first- and second-line DOT, unrelated to hormonal status, may result from a primary characteristic of the intrinsic tumor subtype, that impacts acquired resistance. Longer observations in larger patient cohorts are required to confirm this observation. [Table: see text]

Abstract
OBJECTIVE To investigate endocrine comorbidities in patients with psoriatic arthritis (PsA). METHODS A retrospective, cross-sectional study was performed with the database of Clalit Health Services, the largest healthcare provider in Israel, between 2002 and 2014. Patients with PsA were identified and matched by age and sex to healthy controls. The following morbidities were analyzed: hypo/hyperthyroidism, hypo/hyperparathyroidism, hyperprolactinemia, Cushing disease, Addison disease, diabetes insipidus, diabetes mellitus (DM), pituitary adenoma, acromegaly, and osteoporosis. Descriptive statistics were applied. The associations between PsA and endocrine comorbidities were analyzed by univariable and multivariable analysis. RESULTS The study included 3161 patients with PsA, 53.4% women, mean age 58.4 ± 15.4 years, and 31,610 controls. Comparative analyses yielded higher proportion of hypothyroidism (12.7% vs 8.6%, p < 0.0001), Cushing disease (0.3% vs 0.1%, p < 0.0001), osteoporosis (13.2% vs 9.1%, p < 0.0001), and DM (27.9% vs 20.7%, p < 0.0001) in the PsA group compared with the control group. In the multivariable regression analysis, the following diseases were more frequent in the PsA group: hypothyroidism (OR 1.61, 95% CI 1.47-1.81), DM (OR 1.35, 95% CI 1.18-1.42), Cushing disease (OR 3.96, 95% CI 1.67-9.43), and osteoporosis (OR 1.56, 95% CI 1.37-1.78). CONCLUSION PsA is associated with a high frequency of hypothyroidism, osteoporosis, DM, and Cushing disease. Awareness of these comorbidities may help physicians provide the optimal medical care to patients with PsA.

Abstract
Comorbidities associated with psoriatic arthritis (PsA) include cardiovascular diseases, diabetes mellitus, and obesity. This study evaluated the association between PsA and common gastrointestinal (GI) diseases. A retrospective study was performed in Israel's largest health care provider database between 2002 and 2013. 3161 PsA patients were matched for age and sex with 31610 randomly selected patients. We searched these patients' records for the presence of peptic ulcer disease (PUD), reflux esophagitis, Crohn's disease, ulcerative colitis, irritable bowel syndrome (IBS) and celiac disease. T-test was used to compare continuous variables and a Chi-square test was used for categorical variables. Multivariate logistic regression models were used to assess the association between PsA and GI comorbidities. PsA was associated with Crohn's disease (OR 2.4, 95 %CI: 1.75-3.32, p < 0.0001), ulcerative colitis (OR 2.1, 95 %CI: 1.33-3.26, p = 0.001), reflux esophagitis (OR 1.6, 95 %CI: 1.44-1.78, p < 0.0001), PUD (OR 1.5, 95 %CI: 1.31-1.63, p < 0.0001) and IBS (OR 1.4, 95 %CI: 1.01-1.86, p = 0.045). After controlling for known risk factors, the association remained significant between PsA and Crohn's disease (OR 2.2, 95 %CI: 1.59-3.03, p < 0.0001), ulcerative colitis (OR 1.9, 95 %CI: 1.21-3.00, p = 0.005), reflux esophagitis (OR 1.5, 95 %CI: 1.31-1.63, p < 0.0001), and PUD (OR 1.3, 95 %CI: 1.12-1.47, p < 0.0001). No significant association was found between PsA and celiac disease. In the current study PsA was associated with gastrointestinal morbidities including Crohn's disease, ulcerative colitis, PUD and IBS. Physicians treating patients with PsA should be aware of these associations.

Abstract
539 Background: Based on a single phase 3 study, the mTOR inhibitor tem was approved as 1st line therapy for prmRCC. However, in daily practice, prmRCC pts are often treated with the VEGFR and PDGFR inhibitor su. We aimed to compare the clinical effectiveness of su vs tem in prmRCC pts. Methods: We performed an international multicenter retrospective study of pts with prmRCC (HENG criteria), who were treated in 8 centers across 2 different countries. 31 pts were treated with 1st line tem. Each tem treated pt was individually matched with a 1st line su treated pt, by clinicopathologic factors. The effect of tx type (tem vs su) on clinical benefit, progression free survival (PFS) and overall survival (OS), was tested using a chi-square test and partial likelihood test from cox model. Furthermore, univariate and multivariate analyses of association between clinicopathologic factors and tx type (tem vs su), and outcome were performed using the entire pt cohort (n=62). Results: The groups were matched by age (median 65), gender (male 68%), prior nephrectomy (58%), renal cell carcinoma histology (clear cell 81%), smoking status (active in 35%), use of angiotensin system inhibitors (42%), and pre-tx neutrophil to lymphocyte ratio >3 (58%). In tem vs su treated pts, clinical benefit (partial response + stable disease) was 61% (n=19) (partial response 6%, n=2) vs 71% (n=22) (partial response 29%, n=9) (p=0.62). Median PFS was 5 vs 8 mos (p=0.08), and median OS 9 vs 17 mos (p=0.03). In multivariate analyses of the entire pt cohort (n=62), su tx was independently associated with OS (HR 0.6, p=0.001). Conclusions: In prmRCC patient, the VEGFR inhibitor su may be associated with an improved outcome vs the mTOR inhibitor tem.

Abstract
Drug survival has recently become an important clinical issue in psoriasis. However, there has been little research into factors associated with drug survival of methotrexate and acitretin. The aim of this study was to investigate factors associated with drug survival of methotrexate and acitretin treatment for psoriasis. Survival analysis was performed in patients who received methotrexate or acitretin for the treatment of psoriasis, drawn from the Clalit Health Services database. Investigated factors included demographic variables, obesity, metabolic syndrome, psoriatic arthritis, administration route and folic acid supplementation. Among 6,256 patients, factors associated with treatment drop-out were: younger age (p <0.001) and psoriatic arthritis (acitretin p < 0.001). For methotrexate, metabolic syndrome (p = 0.033), intramuscular administration route of injection (p <0.001) and lack of folic acid supplementation (p <0.001) were associated with treatment drop-out. In patients with psoriasis, some ancillary factors may modify the drug survival of acitretin and methotrexate.

Second-Line Treatment of Her2-Positive Metastatic Breast Cancer: Trastuzumab beyond Progression or Lapatinib? A Population Based Cohort Study. PLoS One 2015; 10:e0138229. [PMID: 26375590 PMCID: PMC4574060 DOI: 10.1371/journal.pone.0138229] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Accepted: 08/26/2015] [Indexed: 11/18/2022] Open
Abstract
Background The relative efficacy of lapatinib vs. continuing trastuzumab beyond progression (TBP) in HER2-positive metastatic breast cancer (MBC) patients, who progressed on first-line trastuzumab, is still unclear. The objective of this population based cohort study was to compare outcomes of lapatinib vs. TBP in daily practice. Methods All HER2-positive MBC patients who began second-line anti HER2 therapy between 1st January 2010 and 30th August 2013 were selected from Clalit Health Services’ (CHS) electronic database. Available data on patient and disease characteristics and treatments were analyzed. The primary endpoint was overall survival (OS). Outcomes were compared using the Kaplan-Meier (log-rank) method and Cox proportional hazards model. Results 64 patients received second-line lapatinib and 93 TBP. The two treatment groups were similar in age and co-morbidity rates, but differed in proportion of prior adjuvant trastuzumab (lapatinib: 29.7%, TBP: 16.1%, P = 0.043) and rates of prior brain metastases (lapatinib: 32.8%, TBP: 10.8%, P = 0.01). Lapatinib median OS was 13.0 months (95% CI: 9.5–16.5) vs. 31.0 for TBP (95% CI: 20.6–41.4), P<0.001. On multivariate analysis, longer OS was preserved for TBP, after controlling for differences in age, adjuvant trastuzumab, duration of first-line trastuzumab therapy, brain metastases, visceral metastases and hormonal treatment [Hazard Ratio (HR) = 0.63, 95% CI: 0.40–0.99, P = 0.045]. Conclusion In this comparative cohort study, OS of HER2-positive MBC patients treated with TBP was significantly longer than with lapatinib. These results might be especially relevant in settings where ado-trastuzumab-emtansine (TDM-1), the current preferred agent in this setting, is not available yet for patients.

Abstract
BACKGROUND After a decade of extensive use, the actual contribution of bevacizumab in first-line treatment of metastatic colorectal cancer (mCRC) is still unclear. OBJECTIVE To evaluate 'real-life' outcomes of patients with mCRC before and after the introduction of bevacizumab to standard mCRC first-line practice. METHODS Using the computerized administrative database of Clalit Health Services' (CHS), Israel's largest health care provider, we retrospectively compared two cohorts (n = 1739): (A) all CHS' patients diagnosed with mCRC between January 2000 and December 2004 that received first-line irinotecan or oxaliplatin-based combination chemotherapy (before bevacizumab was introduced) (n = 1052), and (B) all patients that started first-line irinotecan or oxaliplatin combination chemotherapy together with bevacizumab between September 2006 and December 2009 (after bevacizumab was fully reimbursed in Israel for mCRC first-line therapy) (n = 687). The primary endpoint was overall survival (OS) and secondary endpoints were first-line progression-free survival (PFS) and metastatectomy rates. RESULTS Median OS was longer in Cohort B than in Cohort A [23.0 months vs.15.0, adjusted hazard ratio (HR), 0.75]. Secondary outcomes were also better; PFS of 14.0 months vs. 9.8 in the earlier period (HR, 0.75) and metastatectomy rate of 8.1% versus 3.9%. The longer OS in Cohort B was preserved even after controlling for latter-line epidermal growth factor receptor (EGFR) inhibitor use (HR = 0.77). CONCLUSION In this analysis, OS, PFS and metastatectomy rates of first-line treatment of mCRC were significantly higher in the later period of the study. These results, derived from 'real-life' practice, suggest that the use of bevacizumab, among other alterations in the clinical management of mCRC between the two periods, might have had a significant contribution to these outcomes, and may therefore support the current practice of adding bevacizumab to first-line treatment of mCRC.

Abstract
OBJECTIVES To study the association between traditional disease-modifying antirheumatic drugs (c-DMARD) or anti-TNF-α agents and herpes zoster (HZ) in patients with psoriatic arthritis (PsA). METHODS A retrospective cohort study was conducted in patients with PsA between 2002 and 2013. Patients were grouped as follows: no DMARDs (Group A); c-DMARDs (Group B); anti-TNF-α agents (Group C); anti-TNF-α agents in combination with c-DMARDs (Group D). Crude incidence rates (IR) were calculated as number of HZ episodes per 1000 patient-years. A Cox regression model was used to adjust for HZ risk factors (age, gender, steroid use, Charlson Comorbidity Index score, and previous treatment) in order to estimate their contribution to the risk of the first HZ event. RESULTS The study included 3128 patients, mean age 50.26±14.54 years; 46.2% male. During a period of 20 096 person-years 182 HZ events were observed. The crude IR (95% CI) of HZ in the study population was 9.06 per 1000 patient-years, and in Groups A-D 7.36 (5.41 to 9.79), 9.21 (7.5 to 11.21), 8.64 (4.84 to 14.26), 17.86 (10.91 to 27.58), respectively. In a multivariate analysis, age (HR 1.01, 95% CI 1.00 to 1.02), treatment with steroids (HR 1.08, 95% CI 1.04 to 1.13), and a combination of anti-TNF-α agents and c-DMARDs (HR 2.37, 95% CI 1.32 to 4.22) were significantly associated with HZ events. CONCLUSIONS In our database, the risk of HZ was significantly increased with age, treatment with steroids, and combination of anti-TNF-α agents and c-DMARDs, but not with c-DMARDs or anti-TNF-α therapy alone. Time to HZ event was shorter in patients treated with anti -TNF-α agents.

Abstract
639 Background: L and T “beyond progression” (TBP) for MBC pts who progressed on 1st line therapy with T, are both reimbursed in Israel since 1/2010. The relative efficacy of L vs. T when combined with chemotherapy in 2nd line therapy for HER2+ MBC is unknown. In this retrospective database study we compared outcomes of 2ndline L or TBP, in the daily practice ("real life") in Israel. Methods: Using the computerized databases of Clalit Health Services' (CHS), Israel's largest health care provider, we identified all MBC pts that received 2nd line anti HER2 therapy, with either L or TBP after a 1stline protocol containing T, between 1/1/2010 and 31/12/2011. Pts characteristics and treatments were retrieved. The primary end point was overall survival (OS) defined as the time interval between date of initiation of 2nd line anti HER2 therapy and death or last day of follow-up. Secondary endpoint was progression free survival (PFS), defined as duration of 2nd line therapy. Results: The study population included 83 pts (28 L and 55 TBP). Mean age (59.9 vs. 61.4) and average Charlson co-morbidity index score (6.54 vs. 6.13) were similar between the cohorts. The groups differed in rates of prior adjuvant T (32.1% vs. 10.9%, p=0.017). The interim cutoff date for analysis was 31/12/2012 (allowing at least 12 months of follow-up). Median OS was 10.0 months for L pts (95% CI: 7.41–12.59) and was not reached for TBP, with a total of 31 deaths: 19 [67.9%] in the L group and 22 [40.0%] in the TBP group. A Cox regression showed an adjusted hazard ratio (HR) of 1.44 (95% CI 0.74-2.81), not significant (p=0.28).Prior adjuvant therapy with T was found to be a significant cofounder; HR=3.16 (95% CI 1.52-6.56). Median PFS was 6.0 months (95% CI: 4.31–7.69) for L and 7.0 months (95% CI: 4.30-9.70) for TBP, with a Cox regression adjusted HR of 0.87 (95% CI: 0.50-1.52), not statistically significant (p=0.87). Conclusions: In this retrospective database analysis, our interim results suggest no statistically significant difference in OS and PFS between L and TBP, as 2nd line therapy for HER2+ MBC, however the data showed a strong trend toward a survival benefit with TBP. A longer follow-up is required.

Abstract
CONTEXT Low serum calcidiol has been associated with multiple comorbidities and mortality but no "safe" range has been found for the upper concentration. OBJECTIVE We aim to establish the upper threshold of serum calcidiol, beyond which there is an increased risk for acute coronary syndrome and/or mortality. DESIGN, SETTING, AND PARTICIPANTS We extracted data for 1,282,822 Clalit Health Services members aged >45 between July 2007 and December 2011. Records of mortality or acute coronary syndrome were extracted during the follow-up period. Kaplan-Meier analysis calculated time to episode and Cox regression models generated adjusted hazard ratios for episode by calcidiol group (<10, 10.1-20, 20.1-36, and >36.1 ng/mL). OUTCOME MEASURES Acute coronary syndrome subsuming all-cause mortality. RESULTS During the 54-month study period, 422,822 Clalit Health Services members were tested for calcidiol, of which 12,280 died of any cause (905 with acute coronary syndrome) and 3933 were diagnosed with acute coronary syndrome. Compared to those with 20-36 ng/mL, the adjusted hazard ratios among those with levels of <10, 10-20, and >36 ng/mL were 1.88 (confidence interval [CI]: 1.80-1.96), 1.25 (CI: 1.21-1.30), and 1.13 (CI: 1.04-1.22) (P < .05), respectively. LIMITATIONS The study cohort comprised only 30% of the population, those tested for vitamin D. The small sample size of those with calcidiol >36 ng/mL prevented further analysis of this group. CONCLUSIONS Vitamin D in the 20-36 ng/mL range was associated with the lowest risk for mortality and morbidity. The hazard ratio below and above this range increases significantly.
