Hospital Healthcare Resource Utilization and Associated Hospital Costs of Patients With Lupus Nephritis in China: A National Administrative Claim Database Study. Value Health Reg Issues 2024; 43:101001. [PMID: 38850589 DOI: 10.1016/j.vhri.2024.101001] [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: 06/02/2023] [Revised: 02/08/2024] [Accepted: 03/11/2024] [Indexed: 06/10/2024]
Abstract
OBJECTIVES Assess hospital healthcare resource utilization (HCRU) and associated hospital costs of patients with lupus nephritis (LN) in China and compare these outcomes with a systemic lupus erythematosus (SLE) cohort (SLE with/without LN) as well as exploring the effect of end-stage kidney disease (ESKD). METHODS This retrospective administrative claims-based analysis identified patients with SLE and SLE with LN from China using diagnosis codes and keywords. Patients with LN were subcategorized by presence of ESKD. Outcomes included all-cause and disease-specific HCRU (defined as healthcare visits including inpatient and outpatient visits) and medical costs (in 2022 US dollars). RESULTS In total, 3645 patients with SLE were included, of whom 404 (11%) had LN. Among those with LN, 142 (35%) had ESKD. Median (interquartile range) all-cause healthcare visits per patient per month (PPPM) was significantly greater for patients with LN (2.08 [4.01]) vs SLE (0.92 [1.64]; P < .0001). Patients with LN and ESKD (3.00 [4.18]) had numerically more all-cause healthcare visits PPPM compared with LN patients without ESKD (1.50 [3.45]). Median all-cause costs PPPM were significantly greater among patients with LN ($287.46 [477.15]) vs SLE ($113.09 [267.39]; P < .0001) and numerically higher for patients with LN and ESKD ($466.29 [958.90]) vs LN without ESKD ($223.50 [319.56]). CONCLUSIONS Chinese patients with LN had greater HCRU and hospital healthcare costs compared with the general SLE cohort. This burden was higher for those with ESKD. These data highlight the substantial HCRU among patients with LN in China, especially those with ESKD, suggesting the need for early diagnosis and timely management of LN to mitigate the economic burden.

Healthcare resource utilization and costs in patients with a newly confirmed diagnosis of lupus nephritis in the United States over a 5-year follow-up period. BMC Health Serv Res 2024; 24:691. [PMID: 38822336 PMCID: PMC11143616 DOI: 10.1186/s12913-024-11060-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 04/29/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND We aimed to describe healthcare resource utilization (HCRU) and healthcare costs in patients with newly confirmed lupus nephritis (LN) in the United States over a 5-year follow-up period. METHODS This retrospective, longitudinal cohort study (GSK Study 214102) utilized administrative claims data to identify individuals with a newly confirmed diagnosis of LN between August 01, 2011, and July 31, 2018, based on LN-specific International Classification of Diseases diagnosis codes. Index was the date of first LN-related diagnosis code claim. HCRU, healthcare costs, and incidence of systemic lupus erythematosus (SLE) flares were reported annually among eligible patients with at least 5 years continuous enrollment post-index. RESULTS Of 2,159 patients with a newly confirmed diagnosis of LN meeting inclusion and exclusion criteria, 335 had at least 5 years continuous enrollment post-index. HCRU was greatest in the first year post-LN diagnosis across all categories (inpatient admission, emergency room [ER] visits, ambulatory visits, and pharmacy use), and trended lower, though remained substantial, in the 5-year follow-up period. Among patients with LN and HCRU, the mean (standard deviation [SD]) number of ER visits and inpatient admissions were 3.7 (4.6) and 1.8 (1.5), respectively, in Year 1, which generally remained stable in Years 2-5; the mean (SD) number of ambulatory visits and pharmacy fills were 35.8 (25.1) and 62.9 (43.8), respectively, in Year 1, and remained similar for Years 2-5. Most patients (≥ 91.6%) had ≥ 1 SLE flare in each of the 5 years of follow-up. The proportion of patients who experienced a severe SLE flare was higher in Year 1 (31.6%) than subsequent years (14.3-18.5%). Total costs (medical and pharmacy; mean [SD]) were higher in Year 1 ($44,205 [71,532]) than subsequent years ($29,444 [52,310]-$32,222 [58,216]), driven mainly by inpatient admissions (Year 1: $21,181 [58,886]; subsequent years: $7,406 [23,331]-$9,389 [29,283]). CONCLUSIONS Patients with a newly confirmed diagnosis of LN have substantial HCRU and healthcare costs, particularly in the year post-diagnosis, largely driven by inpatient costs. This highlights the need for improved disease management to prevent renal damage, improve patient outcomes, and reduce costs among patients with renal involvement.

Abstract
BACKGROUND A cost of illness (COI) study aims to evaluate the socioeconomic burden that an illness imposes on society as a whole. This study aimed to describe the resources used, patterns of care, direct cost, and loss of productivity due to systemic lupus erythematosus (SLE) in Brazil. METHODS This 12-month, cross-sectional, COI study of patients with SLE (ACR 1997 Classification Criteria) collected data using patient interviews (questionnaires) and medical records, covering: SLE profile, resources used, morbidities, quality of life (12-Item Short Form Survey, SF-12), and loss of productivity. Patients were excluded if they were retired or on sick leave for another illness. Direct resources included health-related (consultations, tests, medications, hospitalization) or non-health-related (transportation, home adaptation, expenditure on caregivers) hospital resources.Costs were calculated using the unit value of each resource and the quantity consumed. A gamma regression model explored cost predictors for patients with SLE. RESULTS Overall, 300 patients with SLE were included (92.3% female,mean [standard deviation (SD)] disease duration 11.8 [7.9] years), of which 100 patients (33.3%) were on SLE-related sick leave and 46 patients (15.3%) had stopped schooling. Mean (SD) travel time from home to a care facility was 4.4 (12.6) hours. Antimalarials were the most commonly used drugs (222 [74.0%]). A negative correlation was observed between SF-12 physical component and SLE Disease Activity Index (- 0.117, p = 0.042), Systemic Lupus International CollaboratingClinics/AmericanCollegeofRheumatology Damage Index (- 0.115, p = 0.046), medications/day for multiple co-morbidities (- 0.272, p < 0.001), SLE-specific drugs/day (- 0.113, p = 0.051), and lost productivity (- 0.570, p < 0.001). For the mental component, a negative correlation was observed with medications/day for multiple co-morbidities (- 0.272, p < 0.001), SLE-specific medications/day (- 0.113, p = 0.051), and missed appointments (- 0.232, p < 0.001). Mean total SLE cost was US$3,123.53/patient/year (median [interquartile range (IQR)] US$1,618.51 [$678.66, $4,601.29]). Main expenditure was medication, with a median (IQR) cost of US$910.62 ($460, $4,033.51). Mycophenolate increased costs by 3.664 times (p < 0.001), and inflammatory monitoring (erythrocyte sedimentation rate or C-reactive protein) reduced expenditure by 0.381 times (p < 0.001). CONCLUSION These results allowed access to care patterns, the median cost for patients with SLE in Brazil, and the differences across regions driven by biological, social, and behavioral factors. The cost of SLE provides an updated setting to support the decision-making process across the country.

Abstract
BACKGROUND AND OBJECTIVE The aim of this research was to investigate the relationship between disease activity and health-related quality of life (HRQoL) in patients with systemic lupus erythematosus (SLE) considering the increased interest in the management of this disease. MATERIALS AND METHODS HRQoL was measured at clinic visits during a 12-month follow-up period using questionnaires on fatigue (FACIT-FATIGUE); quality of life, EuroQol 5-dimension (EQ-5D-5L) health questionnaire with 5 levels; disability, Health Assessment Questionnaire (HAQ), and a Global Health Status (GHS) scale. Disease activity, organ damage and other clinical factors that could affect HRQoL were recorded. The association between disease activity and HRQoL was assessed using Bayesian linear regression models with monotonic effects. RESULTS Data from 70 patients at the baseline visit and 42 patients with 1 year of follow-up were analyzed. At baseline, 28.57% of patients presented Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)>6. In the 70 baseline patients, disease activity was associated with HRQoL in all four parameters. In the 42 patients with 12 months of follow-up, the positive association of disease activity with GHS, FACIT-FATIGUE and EQ-5D-5L and the negative association with HAQ was maintained. Patients who are smokers and those receiving immunosuppressant therapy presented low GHS and FACIT-FATIGUE scores. Moreover, older age at inclusion was significantly associated to low GHS, while low leucocyte and 25-OH-vitamin D levels were associated to fatigue perception in SLE patients. CONCLUSION Our results showed a statistically significant association between disease activity and HRQoL parameters.

Abstract
INTRODUCTION Infections can play an important role in the mortality and morbidity of patients with glomerulonephritis. However, the frequency of infectious complications in primary glomerulonephritis and their burden to the healthcare managements are not clear. METHODS We evaluated the infectious complications in patients with biopsy-proven focal segmental glomerulosclerosis, membranous glomerulonephritis, IgA nephropathy, minimal change disease, membranoproliferative glomerulonephritis, and chronic glomerulonephritis during the last 10 years in a single center. We recorded the demographic, clinical, and laboratory characteristics; treatment modalities; infectious episodes; and infection-related mortality and morbidity of the patients. RESULTS Of the patients, 154 (63.6%) received immunosuppressive treatment and 88 (34.4%) were followed up under conservative treatment. Overall, 118 infectious episodes were noted in 64 patients, with an infection rate of 0.20 per patient-year. Total infectious complications were higher in the immunosuppressive group than in the conservative group (42.1 vs. 23.3%, p = 0.005). Infection-related hospitalizations were also higher in the immunosuppressive group (p = 0.01). The most frequently infected area was the lungs (15.7%). Although bacterial infections were the most common in both groups, 14.9% of the immunosuppressive group had cytomegalovirus (CMV) replication. Age >50 years (OR 2.19, p = 0.03), basal serum albumin <2.5 g/dL (OR 2.28, p = 0.02), cyclophosphamide (OR 2.43, p = 0.02), and cyclosporine (OR 2.30, p = 0.03) were independently associated with experiencing infectious episodes. CONCLUSIONS Because of high seropositivity for CMV in Turkey, it might be a wise approach to use prophylactic antiviral drugs in patients treated with immunosuppressive treatments. Close monitoring of patients with primary glomerulonephritis, especially those treated with immunosuppressive therapy, is important for reducing infection-related morbidity and mortality.

Abstract
OBJECTIVE There is a paucity of data regarding health care costs associated with damage accrual in systemic lupus erythematosus. The present study was undertaken to describe costs associated with damage states across the disease course using multistate modeling. METHODS Patients from 33 centers in 11 countries were enrolled in the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort within 15 months of diagnosis. Annual data on demographics, disease activity, damage (SLICC/American College of Rheumatology Damage Index [SDI]), hospitalizations, medications, dialysis, and selected procedures were collected. Ten-year cumulative costs (Canadian dollars) were estimated by multiplying annual costs associated with each SDI state by the expected state duration using a multistate model. RESULTS A total of 1,687 patients participated; 88.7% were female, 49.0% were white, mean ± SD age at diagnosis was 34.6 ± 13.3 years, and mean time to follow-up was 8.9 years (range 0.6-18.5 years). Mean annual costs were higher for those with higher SDI scores as follows: $22,006 (Canadian) (95% confidence interval [95% CI] $16,662, $27,350) for SDI scores ≥5 versus $1,833 (95% CI $1,134, $2,532) for SDI scores of 0. Similarly, 10-year cumulative costs were higher for those with higher SDI scores at the beginning of the 10-year interval as follows: $189,073 (Canadian) (95% CI $142,318, $235,827) for SDI scores ≥5 versus $21,713 (95% CI $13,639, $29,788) for SDI scores of 0. CONCLUSION Patients with the highest SDI scores incur 10-year cumulative costs that are ~9-fold higher than those with the lowest SDI scores. By estimating the damage trajectory and incorporating annual costs, data on damage can be used to estimate future costs, which is critical knowledge for evaluating the cost-effectiveness of novel therapies.

Real-world treatment patterns, healthcare resource utilisation and costs in patients with systemic lupus erythematosus treated with belimumab: a retrospective analysis of claims data in the USA. Lupus Sci Med 2020; 7:e000357. [PMID: 32341790 PMCID: PMC7174061 DOI: 10.1136/lupus-2019-000357] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 01/29/2020] [Accepted: 02/17/2020] [Indexed: 11/08/2022]
Abstract
Objective To examine the effects of belimumab initiation on healthcare resource utilisation (HCRU) and costs in SLE. Methods This retrospective observational cohort study used healthcare administrative claims data from the IBM MarketScan Commercial Claims and Encounters Database to identify patients with SLE billing codes who received ≥1 intravenous belimumab infusion between March 2011 and December 2015. The first belimumab administration was the ‘index date’. During the 6-month postindex period, nine belimumab infusions were recommended: three during the initiation period and six during the maintenance period. HCRU and cost data for inpatient admissions, emergency department visits, physician office visits, hospital-based outpatient visits, laboratory services, other outpatient services and outpatient pharmacy prescriptions were compared in the 6-month pre/postindex periods. Results Of the 1879 patients with SLE included, 43% received ≥3 intravenous initiation administrations. An average of 5.3 (SD: 2.4) of the nine recommended belimumab administrations were received within 6 months. In the 6-month preindex versus postindex periods, significant reductions were noted for inpatient hospitalisations (18% vs 9%, p<0.001; mean visits: 0.3 vs 0.14, p<0.001) and emergency department visits (40% vs 24%, p<0.001; mean visits; 3.53 vs 1.96, p<0.001). Mean total costs were higher in the 6-month postindex versus preindex period ($41 426 vs $29 270; p<0.001). Conclusions In this study of real-world intravenous belimumab for SLE, adherence to recommended infusion schedules was low. Outpatient healthcare and associated costs were higher in the 6 months after belimumab was initiated, although inpatient costs were lower. Reasons for non-adherence with belimumab and implications should be investigated.

Abstract
Lupus nephritis (LN) is a form of glomerulonephritis that constitutes one of the most severe organ manifestations of the autoimmune disease systemic lupus erythematosus (SLE). Most patients with SLE who develop LN do so within 5 years of an SLE diagnosis and, in many cases, LN is the presenting manifestation resulting in the diagnosis of SLE. Understanding of the genetic and pathogenetic basis of LN has improved substantially over the past few decades. Treatment of LN usually involves immunosuppressive therapy, typically with mycophenolate mofetil or cyclophosphamide and with glucocorticoids, although these treatments are not uniformly effective. Despite increased knowledge of disease pathogenesis and improved treatment options, LN remains a substantial cause of morbidity and death among patients with SLE. Within 10 years of an initial SLE diagnosis, 5-20% of patients with LN develop end-stage kidney disease, and the multiple comorbidities associated with immunosuppressive treatment, including infections, osteoporosis and cardiovascular and reproductive effects, remain a concern. Clearly, early and accurate diagnosis of LN and prompt initiation of therapy are of vital importance to improve outcomes in patients with SLE.

Abstract
OBJECTIVE Lupus low disease activity state (LLDAS) is a potential treat-to-target goal in systemic lupus erythematosus (SLE). This study determined predictors of time to reach LLDAS in a longitudinal cohort. METHODS Patients were grouped according to LLDAS status at cohort entry. Those who did not satisfy LLDAS at cohort entry were analyzed prospectively. The Kaplan-Meier approach was used to estimate the time to LLDAS. Cox regression was used to identify patient characteristics that were associated with time to LLDAS. RESULTS The probability of LLDAS attainment within 1 year was 52% for Caucasians, 36% for African Americans, and 33% for SLE patients with renal involvement. The median time to LLDAS was 1.1 years. In multivariable models, African American ethnicity, baseline prednisone >10 mg daily, hypocomplementemia, baseline damage, and baseline renal activity remained significant predictors of longer time to attain LLDAS, while disease duration <1 year and cutaneous activity were associated with earlier attainment. CONCLUSION LLDAS is potentially attainable in the majority of SLE patients. The time to LLDAS was found to be longer in African American patients with SLE. Characteristics of African American patients with SLE, such as renal activity and hypocomplementemia, were also independent predictors of slower attainment of LLDAS. These findings point to the need to include African American patients with SLE in both clinical and pharmaceutical research.

Abstract
Aim: Therapy for lupus nephritis (LN) requires treatment with immunosuppressive regimens, often including intravenous cyclophosphamide (IVCY), mycophenolate mofetil (MMF) or azathioprine. Additionally, tacrolimus (original form or generic) is recommended to treat LN patients in Asia, including China. However, the cost-effectiveness of tacrolimus therapy has not previously been assessed. We aimed to estimate the cost-effectiveness of tacrolimus in the treatment of moderate-to-severe LN versus standard therapies in China. Materials & methods: This cost-effectiveness model combined a decision-tree/Markov-model structure to map transitions between health states during induction and maintenance treatment phases. Induction with tacrolimus, IVCY or MMF, was followed by tacrolimus, MMF or azathioprine maintenance. Results: According to the model, during induction, complete remission rates were higher with tacrolimus versus IVCY (relative risk 1.40 vs IVCY [deterministic sensitivity analysis minimum 0.92, maximum 2.13]) and time to response was shorter. Relapse rates were lower with tacrolimus versus azathioprine or MMF during maintenance. Tacrolimus induction and maintenance was the most cost-effective regimen, incurring the lowest total costs (CN¥180,448) with the highest quality-adjusted life-years. Conclusion: The model demonstrated that tacrolimus use in both induction and maintenance therapy may be an efficacious and cost-effective treatment for LN in China.

Int J Rheum Dis 2018; 21:1609-1618. [PMID: 30146745 PMCID: PMC6585770 DOI: 10.1111/1756-185x.13363] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2017] [Revised: 06/14/2018] [Accepted: 07/12/2018] [Indexed: 01/20/2023]
Abstract
Aim To describe the healthcare resource utilization (HRU), direct medical costs and clinical characteristics for Japanese patients with mild, moderate or severe systemic lupus erythematosus (SLE). The primary objectives were to describe HRU and examine the direct medical costs for Japanese patients with mild, moderate, or severe SLE over the 3‐year study period. Secondary objectives included recording patient demographics, clinical characteristics and frequency and cost of mild, moderate or severe flares. Exploratory objectives included a description of treatment patterns, and to explore which factors affect medical costs. Methods This retrospective, observational cohort study identified patients with SLE (diagnosed April 2010 to March 2012), from the Japan Medical Data Center claims database. Result The study cohort comprised 295 patients with mild (28, 9.5%), moderate (134, 45.4%), or severe (133, 45.1%) SLE. Outpatient visits, hospitalizations and emergency room stays were experienced by 295 (100%), 116 (39.3%) and 31 (10.5%) patients, respectively, over the 3‐year study period. Over the 3‐year period, the mean total direct medical cost was US$27 004, and cost increased with SLE severity: mild, $5549 moderate, $15 290; and severe, $43 322 (analysis of variance, P < 0.0001). During this period, the majority of patients (282, 95.6%) experienced at least one flare episode and the mean (standard deviation) frequency was 5.5 (3.3) flares. The mean total direct medical cost per flare increased with SLE severity. Conclusion This descriptive study provides information on the economic burden and clinical characteristics of Japanese patients with SLE based on claims data; high levels of HRU and direct medical costs were exhibited, particularly in patients with moderate or severe disease.

Abstract
OBJECTIVES To evaluate healthcare resource (HR) consumption associated with Systemic Lupus Erythematosus (SLE) management in adult patients with active autoantibody positive disease in the Russian Federation, Republic of Kazakhstan, and Ukraine. METHODS The ESSENCE was a retrospective, observational study, and included data on patients' clinical characteristics and SLE-related HR use (laboratory, biopsy, imaging tests, medications, visits to specialists, outpatient visits, hospitalizations) during 2010 from the 12 specialized rheumatologic centers. RESULTS A total of 436 SLE patients were included in the analyses, with 232 patients being enrolled in Russia, 110 in Kazakhstan, and 94 in Ukraine. The mean age was 36-42 years and median SLE duration was 3-6.8 years across the countries. Extrapolation to total country population showed that, in 2010, visits to specialists (who assign treatment for organs involved/damaged by SLE) were the most frequently used HR (from 13,439 visits in Kazakhstan to 23,510 in Russia), followed by hospitalizations (from 2,950 in Kazakhstan to 6,267 in Russia) and outpatient visits (from 1,654 visits in Russia to 8,064 in Kazakhstan). Compared to chronic active patients (SLE persistent during last year), patients with relapsing-remitting SLE (at least one flare alternated by one remission per year) had a higher rate of visits to specialists (100% vs 60.8%, p < .001) and hospitalizations (98.9% vs 60.8%, p < .001). Compared to patients without flares, patients experiencing flares had a higher rate of unplanned visits to specialists (86.2% vs 6.3%, p < .001), were more often hospitalized (both ICU and non-ICU) (100.0% vs 50.0%, p < .001), and had a longer duration of ICU hospitalization (25.9 days vs 17.5 days, p < .001). CONCLUSIONS Specialist visits are the most frequently consumed SLE-related healthcare recourse in the Commonwealth of Independent States (CIS) countries. A relapsing-remitting SLE profile and the occurrence of flares significantly raise healthcare resource consumption.

Abstract
OBJECTIVE Little is known about the long-term costs of lupus nephritis (LN). The costs were compared between patients with and without LN using multistate modeling. METHODS Patients from 32 centers in 11 countries were enrolled in the Systemic Lupus International Collaborating Clinics inception cohort within 15 months of diagnosis and provided annual data on renal function, hospitalizations, medications, dialysis, and selected procedures. LN was diagnosed by renal biopsy or the American College of Rheumatology classification criteria. Renal function was assessed annually using the estimated glomerular filtration rate (GFR) or estimated proteinuria. A multistate model was used to predict 10-year cumulative costs by multiplying annual costs associated with each renal state by the expected state duration. RESULTS A total of 1,545 patients participated; 89.3% were women, the mean ± age at diagnosis was 35.2 ± 13.4 years, 49% were white, and the mean followup duration was 6.3 ± 3.3 years. LN developed in 39.4% of these patients by the end of followup. Ten-year cumulative costs were greater in those with LN and an estimated glomerular filtration rate (GFR) <30 ml/minute ($310,579 2015 Canadian dollars versus $19,987 if no LN and estimated GFR >60 ml/minute) or with LN and estimated proteinuria >3 gm/day ($84,040 versus $20,499 if no LN and estimated proteinuria <0.25 gm/day). CONCLUSION Patients with estimated GFR <30 ml/minute incurred 10-year costs 15-fold higher than those with normal estimated GFR. By estimating the expected duration in each renal state and incorporating associated annual costs, disease severity at presentation can be used to anticipate future health care costs. This is critical knowledge for cost-effectiveness evaluations of novel therapies.

Abstract
Background Patient-reported outcomes in lupus nephritis (LN) are not well studied. Studies with disease-targeted PRO tool in LN do not exist. Herein, we describe quality of life (QOL: HRQOL & non-HRQOL) among LN patients using LupusPRO. Methods International, cross-sectional data from 1259 patients with systemic lupus erythematosus (SLE) and LupusPRO were compared, stratified by (a) presence of LN (ACR classification criteria (ACR-LN)) at any time and, (b) active LN (on SLEDAI) at study visit. Damage was assessed by SLICC/ACR-SDI. Multivariate regression analyses for QOL against ACR-LN (active LN) after adjusting for age, gender, ethnicity and country of recruitment were performed. Results Mean (SD) age was 41.7 (13.5) yrs, 93% were women. Five hundred and thirty-nine of 1259 SLE patients had ACR-LN. ACR-LN group was younger, were more often on immunosuppressive medications, had worse QOL on lupus medications and procreation than non-ACR-LN patients. HRQOL and non-HRQOL scores were similar in both groups. One hundred and twenty-nine of 539 ACR-LN patients had active LN. Active LN group was younger, had greater disease activity and had worse HRQOL and non-HRQOL compared to patients without active LN. Specific domains adversely affected were lupus symptoms, lupus medications, procreation, emotional health, body image and desires-goals domains. Patients with ACR-LN and active LN fared significantly worse in lupus medications and procreation HRQOL domains, even after adjusting for age, ethnicity, gender and country of recruitment. Conclusions Lupus nephritis patients have poor QOL. Patients with active LN have worse HRQOL and non-HRQOL. Most domains affected are not included in the generic QOL tools used in SLE. LN patients must receive discussion on lupus medications and procreation issues. Patients with active LN need comprehensive assessments and addressal of QOL, along with treatment for active LN.

Abstract
OBJECTIVE To determine total physician encounters, emergency room (ER) visits, and hospitalizations in an incident cohort of systemic lupus erythematosus (SLE) cases and matched control patients over 13 years. METHODS A retrospective cohort study was performed utilizing administrative health care data from approximately 1 million people with access to universal health care. Using International Classification of Diseases, Ninth and Tenth Revisions diagnostic codes, 7 SLE case definitions were used. Each case was matched by age and sex to 4 randomly selected controls. Data included physician billings, ER visits, and hospital discharges over 13 years. RESULTS The number of incident SLE cases varied from 564 to 4,494 depending on the case definition used. The mean age varied from 47.7 to 50.6 years and the proportion of females from 78.0% to 85.1%. SLE utilization of physicians was highest in the index year, and declined significantly thereafter for all case definitions. By the fourth year, encounters with subspecialty physicians fell by 60% (rheumatologists), 50% (internists), and 31% (other physicians). In contrast, visits to family physicians fell by only 9%. Visits to the ER and hospital admissions for SLE cases were also more frequent early in the disease course and fell significantly over the study for both ER visits (all case definitions) and hospitalizations (2 of 7 case definitions). CONCLUSION In SLE patients, health care utilization is highest in the first few years following the diagnosis, which is also the time of maximal involvement by rheumatologists. Utilization declines over time, and encounters with patients' family physicians predominate over those of other physician groups.

Abstract
Systemic lupus erythematosus (SLE) is associated with significant mortality, morbidity and cost for the individual patient and society. In the United States, African Americans (AAs) have 3-4 times greater prevalence of lupus, risk of developing lupus at an earlier age and lupus-related disease activity, organ damage and mortality compared with whites. Evidence-based self-management interventions that incorporate both social support and health education have reduced pain, improved function and delayed disability among patients with lupus. However, AAs and women are still disproportionately affected by lupus. This article presents the argument that peer mentoring may be an especially effective intervention approach for AA women with SLE. SLE peers with a track record of success in lupus management and have a personal perspective that clinicians often lack. This commonality and credibility can establish trust, increase communication and, in turn, decrease disparities in healthcare outcomes.

Abstract
Objective To identify fixed and time-varying predictors of incident proteinuria. Methods This analysis was based on patients who did not have a history of diabetes and who did not have a prior episode of renal involvement. We defined an incident case of proteinuria as two or more measures of urine protein to creatinine ratio (or 24-hour protein measure) greater than 0.5 in two visits separated by more than 30 days and less than 180 days. We estimated rates of incident proteinuria in subgroups of patients with lupus defined by time-invariant and time-varying predictors. Results Among 895 patients included in the analysis, 840 (94%) were female, and 518 (58%) were Caucasian, 304 (34%) African-American, with mean age of 42 years at the start of follow-up. We observed 57 incident cases of proteinuria over a span of 4669 person-years of cohort follow-up. The overall rate of incident proteinuria was 12.2 per 1000 person-years. The rate was significantly lower among those of older age, and higher among those who were not Caucasian. In those with a very low C3 measure in a previous cohort visit, the rate was increased by a factor of 16.1 and in those with a very low C4 by 16.3. The rate among those prescribed hydroxychloroquine or ACE inhibitors/ARB was similar to those not on them. Conclusions Older patients with SLE are at low risk for developing proteinuria. There was not strong evidence that hydroxychloroquine or angiotensin-converting-enzyme (ACE) inhibitor reduced the risk of proteinuria. The highest rates of incident proteinuria were among those with recent low complement.

Abstract
Although challenging, developing evidence-based approaches to an early and accurate diagnosis of systemic lupus erythematosus is a key approach to preventing disease and lupus-associated morbidity and mortality. Advances in our understanding of preclinical and incomplete lupus erythematosus have enabled the identification of risk factors that may predict disease and the development of potential strategies aimed at primary prevention. Emerging data support the notion that there is a temporal disease progression from initial asymptomatic autoimmunity (preclinical lupus) through early clinical features of the disease (incomplete lupus erythematosus) to finally becoming fully classifiable systemic lupus erythematosus (complete lupus erythematosus). Here, we review the demographic, clinical, biomarker as well as genetic and environmental features that are reported to increase the risk of disease progression. Based on these risk factors, we propose a clinical care pathway for patients with early disease. We envisage that such a pathway, through early identification of disease, may improve patient outcomes, while reducing health care costs.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can potentially lead to serious organ complications and even death. Its global burden - in terms of incidence and prevalence, differential impact on populations, economic costs and capacity to compromise health-related quality of life - remains incompletely understood. The reported worldwide incidence and prevalence of SLE vary considerably; this variation is probably attributable to a variety of factors, including ethnic and geographic differences in the populations being studied, the definition of SLE applied, and the methods of case identification. Despite the heterogeneous nature of the disease, distinct patterns of disease presentation, severity and course can often be related to differences in ethnicity, income level, education, health insurance status, level of social support and medication compliance, as well as environmental and occupational factors. Given the potential for the disease to cause such severe and widespread organ damage, not only are the attendant direct costs high, but these costs are sometimes exceeded by indirect costs owing to loss of economic productivity. As an intangible cost, patients with SLE are, not surprisingly, likely to endure considerably reduced health-related quality of life.

Abstract
Analyses of the medical and economic burden of chronic disorders such as systemic lupus erythematosus (SLE) are valuable for clinical and health policy decisions. We performed a chart-based review of 215 adult SLE patients with active autoantibody-positive disease at the predefined ratio of 30% severe (involvement of major organs requiring treatment) and 70% non-severe, followed at seven hospital centres in Greece. We reviewed 318 patients consecutively registered over three months (sub-study). Disease activity, organ damage, flares and healthcare resource utilization were recorded. Costs were assessed from the third-party payer perspective. Severe SLE patients had chronic active disease more frequently (22.4% vs 4.7%), higher average SLE disease activity index (SLEDAI) (10.5 vs 6.1) and systemic lupus international collaborating clinics (SLICC) damage index (1.1 vs 0.6) than non-severe patients. The mean annual direct medical cost was €3741 for severe vs €1225 for non-severe patients. Severe flares, active renal disease and organ damage were independent cost predictors. In the sub-study, 19% of unselected patients were classified as severe SLE, and 30% of them had chronic active disease. In conclusion, this is the first study to demonstrate the significant clinical and financial burden of Greek SLE patients with active major organ disease. Among them, 30% display chronic activity, in spite of standard care, which represents a significant unmet medical need.

Int J Nephrol 2015; 2015:917567. [PMID: 26600951 PMCID: PMC4639665 DOI: 10.1155/2015/917567] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2015] [Revised: 09/23/2015] [Accepted: 09/29/2015] [Indexed: 12/05/2022] Open
Abstract
Background/Aims. We aimed to examine the cost-effectiveness of mycophenolate mofetil (MMF) and azathioprine (AZA) as maintenance therapy for patients with Class III and Class IV lupus nephritis (LN), from a United States (US) perspective. Methods. Using a Markov model, we conducted a cost-utility analysis from a societal perspective over a lifetime horizon. The modeled population comprised patients with proliferative LN who received maintenance therapy with MMF (2 gm/day) versus AZA (150 mg/day) for 3 years. Risk estimates of clinical events were based on a Cochrane meta-analysis while costs and utilities were retrieved from other published sources. Outcome measures included costs, quality-adjusted life-years (QALY), incremental cost-effectiveness ratios (ICER), and net monetary benefit. Results. The base-case model showed that, compared with AZA strategy, the ICER for MMF was $2,630,592/QALY at 3 years. Over the patients' lifetime, however, the ICER of MMF compared to AZA was $6,454/QALY. Overall, the ICER results from various sensitivity and subgroup analyses did not alter the conclusions of the model simulation. Conclusions. In the short term, an AZA-based regimen confers greater value than MMF for the maintenance therapy of proliferative LN. From a lifelong perspective, however, MMF is cost-effective compared to AZA.

Abstract
OBJECTIVE To study the annual direct and indirect costs in systemic lupus erythematosus (SLE) and how age, disease manifestations, disease activity, and organ damage influence total costs and predicted costs for SLE. METHODS Clinical data on all patients with a diagnosis of SLE living in a defined area in southern Sweden during eight years were linked to health authority registries and the social insurance system which contain data on cost. Cost data on four matched population controls for each patient were also extracted. The controls were matched for age, sex, and area of residence. RESULTS Data from 127 patients with SLE and 508 population controls were extracted. The mean annual total cost for SLE patients was SEK 180,520 ($30,093); the highest costs were found in the subgroup with nephritis SEK 229,423 ($38,246). The total costs for the patient group were significantly higher (p < 0.05) compared to the population controls of SEK 59,985 ($10,000). Of the total costs, 72% were due to indirect costs, 3% to SLE-specific pharmaceuticals, and the remaining 25% were in- and outpatient related costs. During the study period, inpatient days decreased by 60%, while outpatient contacts increased by 25%. Age (inverse relation), increasing disease activity, and acquired organ damage were significant predictors of total costs (all p < 0.05). CONCLUSION The total annual costs for unselected SLE patients were found to be three times those for matched population controls. Important predictors of total costs were found.

Changes in the morbidity and costs of systemic lupus erythematosus in Poland in the years 2008-2012. Reumatologia 2015; 53:79-86. [PMID: 27407232 PMCID: PMC4847273 DOI: 10.5114/reum.2015.51507] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Accepted: 04/17/2015] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVES The goal of the article is to present the changes in morbidity and costs of systemic lupus erythematosus (SLE) in Poland in the 2008-2012 period, depending on the province of residence of the patients based on data reported to the public payer - the National Health Fund. MATERIAL AND METHODS Based on the ICD-10 code and the patient's personal identity number, the number of patients and medical costs (cost of hospitalization, pharmaceutical, medical procedures, dialysis and specialist consultations) were calculated by province (voivodeship) and urban or rural residence. RESULTS Annually on average in the assessed period in Poland approximately 20 000 patients were diagnosed with SLE. The studied group was dominated by women (they were 5.2 times more numerous). The morbidity rate was 52.183 patients per 100 thousand inhabitants. Most patients were in the age range of 48-56 years. Average annual expenses for this group of patients over the examined period were USD 16,327 million. Two times more was expended on patients inhabiting cities, approximately 4 times more on women. Calculated per patient, the average cost of therapy was USD 810.63. CONCLUSIONS The population of SLE patients in Poland is highly stable. The results of analysis indicate 1.64 times more frequent occurrence in urban areas, which may be connected with availability of doctors. The SLE treatment costs in Poland are much lower than in other countries, which is related mainly to the fact that therapy with biological drugs is not financed.

Abstract
Background: Although the survival rate has considerably improved, many patients with systemic lupus erythematosus (SLE) develop irreversible organ damage. Objectives: The objectives of this paper are to characterize cumulative damage in SLE patients and identify variables associated with its presence and severity. Methods: A cross-sectional analysis of SLE patients from the Portuguese Lupus register Reuma.pt/SLE in whom damage assessment using the SLICC/ACR-Disability Index (SDI) was available was performed. Predictor factors for damage, defined as SDI ≥ 1, were determined by logistic regression analyses. A sub-analysis of patients with severe damage (SDI ≥ 3) was also performed. Results: In total, 976 patients were included. SDI was ≥1 in 365 patients, of whom 89 had severe damage. Musculoskeletal (24.4%), neuropsychiatric (24.1%) and ocular (17.2%) domains were the most commonly affected. Older age, longer disease duration, renal involvement, presence of antiphospholipid antibodies and current therapy with steroids were independently associated with SDI ≥ 1. The subpopulation with severe damage had, in addition, a greater interval between the first manifestation attributable to SLE and the clinical diagnosis as well as and more frequently early retirement due to SLE. Conclusions: This large lupus cohort confirmed that demographic and clinical characteristics as well as medication are independently associated with damage. Additionally, premature retirement occurs more often in patients with SDI ≥ 3. Diagnosis delay might contribute to damage accrual.

Abstract
In emerging countries, systemic lupus erythematosus (SLE) has been associated with several unfavorable outcomes including disease activity, damage accrual, work disability and mortality. Poor socioeconomic status (SES) and lack of access to healthcare, especially in medically underserved communities, may be responsible for many of the observed disparities. Diagnostic delay of SLE or for severe organ damages (renal involvement) have a negative impact on those adverse outcomes in lupus patients who either belong to minority groups or live in emerging countries. Longitudinal and observational prospective studies and registries may help to identify the factors that influence poor SLE outcomes in emerging countries. Infection is an important cause of mortality and morbidity in SLE, particularly in low SES patients and tuberculosis appears to be frequent in SLE patients living in endemic areas (mainly emerging countries). Thus, tuberculosis screening should be systematically performed and prophylaxis discussed for patients from these areas. SLE treatment in the developing world is restricted by the availability and cost of some immunosuppressive drugs. Moreover, poor adherence has been associated to bad outcomes in lupus patients with a higher risk of flares, morbidity, hospitalization, and poor renal prognosis. Low education and the lack of money are identified as the main barrier to improve lupus prognosis. Newer therapeutic agents and new protocols had contributed to improve survival in SLE. The use of corticoid-sparing agents (hydroxychloroquine, methotrexate, azathioprine and mycophenolate mofetif) is one of the most useful strategy; availability of inexpensive generics may help to optimize access to these medications.

Abstract
PURPOSE To evaluate in France the annual direct medical cost of adult patients with active systemic lupus erythematosus (SLE) on medication and estimate the cost of a flare. METHODS A two-year, observational, retrospective, multicenter study, carried out between December 2010 and February 2011. Patients' characteristics, SLE disease activity and severity, rate of flares, healthcare consumption (medications, hospitalisations, etc.) were evaluated. Medical costs were assessed from the national Health Insurance perspective. Cost predictors were estimated using multivariate regression models. RESULTS Eight centres specialized in SLE management included 93 eligible patients (including 50.5% severe). The mean age was 39.9 (11.9) years and 93.5% were women. At baseline, the mean SLE duration was 9.8 (6.6) years. The mean scores of the SELENA-SLEDAI instrument and the SLICC/ACR index were higher in severe patients (9.8 vs 5.6, and 1.2 vs 0.4 respectively; P<0.001). Over the study period, 51% of patients received the combination containing at least corticosteroids or immunosuppressants. The mean annual direct medical cost of severe patients was €4660 versus €3560 for non-severe patients (non-significant difference). The cost of medications (61.8% of the annual cost) was higher in severe patients (€3214 vs €1856; P<0.05). Immunosuppressants and biologics represented 26.5% and 4.6% of the annual total cost respectively. Patients experienced on average 1.10 (0.59) flares/year, of which 0.50 were severe flare. The occurrence of a new severe flare incremented the annual cost of €1330 (P<0.05). CONCLUSION Medications represented the major component of the annual direct medical cost. Severe flares increase significantly the cost of SLE care management.

Abstract
OBJECTIVE To assess the costs of illness, health-related quality of life (HRQOL) and their associated factors in patients with systemic lupus erythematosus (SLE) in South Korea. METHOD Two hundred and one patients with SLE were enrolled at the Rheumatology clinic of Seoul National University Hospital. Direct, indirect and total costs and HRQOL were measured using hospital electronic data and face-to-face interview. Socio-demographic and clinical factors associated with cost of illness and HRQOL were analyzed using multiple regression and multivariate logistic regression. RESULTS The average total cost of illness was estimated to be KRW 9.82 million (US $ 8993) per year, of which 41.6% was accounted for by direct costs and 58.4% by indirect costs. In multivariate regression, patients with renal involvement and those with depression incurred an average increment in annual total costs of 37.6% (p = 0.050) and 49.1% (p = 0.024), respectively, and an average increment in annual direct costs of 26.4% (p = 0.050) and 43.3% (p = 0.002), respectively, compared with patients without renal involvement and depression, respectively. In addition, disease damage was positively associated with an average increment in annual total and direct costs (55.3%, p = 0.006; 33.3%, p = 0.013, respectively), and the occurrence of indirect costs (OR 2.21, 1.09-4.88). There was no significant difference in HRQOL between patients with and without renal involvement (0.655 vs. 0.693, p = 0.203) CONCLUSION: Renal involvement, depression, and disease damage were major factors associated with higher total and medical costs for patients with SLE in South Korea. Effective treatment of renal disorders and depression may reduce the high economic burden of SLE.

Abstract
Objectives The aim of the Systemic LUpus Erythematosus Cost of Care In Europe (LUCIE) study was to evaluate the annual direct medical costs of managing adults with active autoantibody-positive disease on medication for SLE in secondary care. This paper presents the UK analyses only. Methods A cost-of-illness study was conducted from the perspective of the National Health Service. Health resource utilization data were retrieved over a two-year period from four centres in England and unit cost data were taken from published sources. Results At baseline, 86 patients were included, 38 (44.2%) had severe SLE and 48 (55.8%) had non-severe SLE. The mean (SD) SELENA-SLEDAI score was 7.7 (5.7). The mean (SD) annual direct medical cost of was estimated at £3231 (£2333) per patient and was 2.2 times higher in patients with severe SLE compared with patients with non-severe SLE ( p < 0.001). Multivariate model analyses showed that renal disease involvement ( p = 0.0016) and severe flares ( p = 0.0001) were associated with higher annual direct costs. Conclusions Improvement of the overall stability of SLE and early intervention to minimize the impact of renal disease may be two approaches to mitigate the long-term direct cost of managing SLE patients in the UK.

ACTA ACUST UNITED AC 2013; 65:1865-71. [PMID: 23553077 DOI: 10.1002/art.37953] [Citation(s) in RCA: 106] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2012] [Accepted: 03/21/2013] [Indexed: 12/19/2022]
Abstract
OBJECTIVE To investigate whether an increase in vitamin D levels in patients with systemic lupus erythematosus (SLE) was associated with improvement in disease activity. METHODS A total of 1,006 SLE patients were monitored over 128 weeks. SLE patients with low levels of 25-hydroxyvitamin D (25[OH]D; <40 ng/ml) were given supplements of 50,000 units of vitamin D2 weekly plus 200 units of calcium/vitamin D3 twice daily. Longitudinal regression models were used to estimate the association between levels of 25(OH)D and various measures of disease activity. RESULTS The SLE patients had the following characteristics: 91% were female, their mean age was 49.6 years, and their ethnicity was 54% Caucasian, 37% African American, and 8% other. For those with levels of 25(OH)D <40 ng/ml, a 20-unit increase in the 25(OH)D level was associated with a mean decrease of 0.22 (95% confidence interval [95% CI] -0.41, -0.02) (P = 0.032) in the Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA) version of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). This corresponded to a 21% decrease in the odds of having a SELENA-SLEDAI ≥5 (95% CI 1, 37). The mean urine protein-to-creatinine ratio decreased by 2% (95% CI -0.03, -0.01) (P = 0.0001), corresponding to a 15% decrease in the odds of having a ratio >0.5 (95% CI 2, 27). CONCLUSION We found that a 20-ng/ml increase in the 25(OH)D level was associated with a 21% decrease in the odds of having a high disease activity score and a 15% decrease in the odds of having clinically important proteinuria. Although these associations were statistically significant, the clinical importance is relatively modest. There was no evidence of additional benefit of 25(OH)D beyond a level of 40 ng/ml.

Abstract
OBJECTIVE To evaluate inpatient health care utilization for children with systemic lupus erythematosus (SLE) with and without kidney disease. METHODS The Healthcare Cost and Utilization Project Kids' Inpatient Database for the years 2000, 2003, and 2006 was used for this analysis. SLE hospitalizations from the 2006 cohort were identified and classified as those with versus without kidney involvement by International Classification of Diseases, Ninth Revision, Clinical Modification codes. Analyses were performed to examine determinants of hospitalization charges and changes in charges over time. RESULTS In the US, 7,390 SLE-related pediatric hospitalizations generated $267 million in total charges in 2006. Of these, 4,193 discharges had kidney involvement. The average hospitalization charge was greater for SLE patients with kidney involvement compared to those without kidney involvement ($43,100 versus $28,500; P < 0.0001). In multivariate analysis, kidney involvement remained a significant predictor of hospitalization charges, independent of demographic and hospital characteristics (P < 0.0001). SLE-associated acute kidney failure, transplant, and end-stage kidney disease resulted in greater hospitalization charges than SLE without kidney involvement by $74,900 (P < 0.0001), $32,700 (P = 0.0002), and $27,400 (P < 0.0001), respectively. CONCLUSION In the US, >7,000 hospitalizations occurred in 2006 among children with SLE, with nearly 57% demonstrating kidney involvement. Kidney involvement is a major determinant of hospitalization charges for these children. This study represents one of the first large-scale assessments of in-hospital health care utilization by children with SLE.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterised by variable and unpredictable manifestations that can severely affect a person's physical and mental well-being, social life and ability to acquire and maintain gainful employment. Damage to vital organs may ensue as a result of the disease itself or as a consequence of treatment, and patients often consume substantial health-care resources and incur considerable health-care costs. Furthermore, SLE tends to affect women in young and middle adulthood, at a time in their lives when they are usually most actively engaged in the workforce, and can have important consequences with respect to acquiring and maintaining employment and advancing in one's career. A number of studies have attempted to assess the health-care costs (direct costs) associated with SLE, the effects of SLE on employment and the associated costs due to decreases in work productivity (indirect costs). In this article, we review a number of recent studies that have added to our current understanding of the economic burden of SLE.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organ systems, including the kidneys (lupus nephritis) and the central nervous system (neuropsychiatric lupus, or NPSLE). The healthcare costs and resource utilization associated with treating lupus nephritis and NPSLE in a large US managed care plan were studied. METHODS SLE subjects ≥18 years of age and with claims-based evidence of nephritis or neuropsychiatric conditions were identified from a health plan database. An index date was set as a randomly drawn date from all qualifying claims during 2003-2008 for study subjects. Subjects were matched on the basis of demographic and clinical characteristics to unaffected controls. Costs and resource use were determined during a fixed 12-month post-index period. RESULTS Nine hundred and seven lupus nephritis subjects were matched to controls, and 1062 subjects with NPSLE were matched to controls. Mean overall post-index healthcare costs were significantly higher among subjects with lupus nephritis in comparison to matched controls ($33,472 vs $5347, p < 0.001). Similarly, mean overall post-index healthcare costs were significantly higher among subjects with NPSLE compared to controls ($30,341 vs $4646, p < 0.001). Subjects with lupus nephritis or NPSLE had higher mean post-index numbers of ambulatory visits, specialist visits, emergency department visits and inpatient hospital stays, compared to controls (all p < 0.001). LIMITATIONS Additional research, such as medical chart review, could provide validation for the claims-based identification of lupus nephritis and NPSLE subjects. Also, indirect costs were not evaluated in this study. CONCLUSION Subjects with lupus nephritis or NPSLE have high costs and resource use, compared to unaffected controls.

Abstract
OBJECTIVES To evaluate the annual direct medical cost of managing adult systemic lupus erythematosus (SLE) patients with active autoantibody positive disease in Europe. METHODS A 2-year, retrospective, multicentre, observational study was conducted in five countries (France, Germany, Italy, Spain and the UK). Data included patients' characteristics, disease activity and severity, flare assessments and health resource use (eg, laboratory tests, medications, specialist visits and hospitalisations). Costs were assessed from the public payers' perspective. Cost predictors were estimated by multivariate regression models. RESULTS Thirty-one centres enrolled 427 consecutive eligible patients stratified equally by disease severity. At baseline, mean (SD) age was 44.5 (13.8) years, 90.5% were women and mean (SD) SLE duration was 10.7 (8.0) years. The SELENA-SLEDAI (11.2 vs 5.3) and SLICC/ACR index (1.0 vs 0.7) scores were higher in severe patients. Over the study period, patients experienced on average 1.02 (0.71) flares/year. The mean annual direct medical cost was higher in severe compared to non-severe patients (€4748 vs €2650, p<0.001). Medication costs were €2518 in severe versus €1251 in non-severe patients (p<0.001). Medications represented 53% and 47% of the total cost for severe and non-severe patients, respectively, primarily due to immunosuppressants and biologics. Flares, especially severe flares, were identified as the major cost predictor, with each flare increasing the annual total cost by about €1002 (p<0.001). CONCLUSIONS The annual direct medical cost of SLE patients in Europe is related to disease severity and flares. Medical treatments were the main cost drivers. Severe flares and major organ involvement were identified as important cost predictors.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is prevalent among young female adults, particularly in Asia. In Taiwan, features of end-of-life SLE patients remain unclear. MATERIAL AND METHODS Data regarding SLE patients whose hospitalization ended up with death were collected and analyzed from the repository of the National Health Insurance Research Database, Taiwan, from 2005 to 2007. RESULTS A total of 302 subjects were enrolled and the majority of these were young to middle-aged women (45.8 ±18.5 years); only one third of them were treated by rheumatologists. Eight patients (2.6%) with comorbid cancers received hospice care. Sepsis/bacteremia (42.1%) was the major acute comorbidity. Nephropathy/nephritis (35.1%) represented the major chronic comorbidity. Among 27 subjects with comorbid cancers, gynecological cancers were the most common (18%). Among the inpatient costs, the cost of prescriptions accounted for the majority (21.7 ±11.5%). Under a multivariate logistic regression, advanced age (≥ 65 years) correlated positively with acute lower respiratory conditions (ALRC) and diabetes mellitus (DM), and male gender correlated negatively with nephropathy/nephritis. The nephropathy/nephritis correlated positively with hospital stays > 14 days. The ALRC was closely associated with acute respiratory failure, but not with shock. However, shock was closely associated with hospital stays ≥ 14 days and sepsis/bacteremia. Cancer development was inversely correlated to nephropathy/nephritis, acute respiratory failure, and shock (all p < 0.05). CONCLUSIONS The end-of-life SLE patients revealed aforementioned characteristics and relationships. Sepsis/bacteremia, acute respiratory failure, and ALRC contributed most frequently to the ultimate death of acutely ill SLE patients.

Abstract
OBJECTIVE Autoantibodies are important in the diagnosis and classification of systemic lupus erythematosus (SLE), but whether they correlate with changes in disease activity within individual patients is controversial. We assessed the association between changes in SLE global and renal activity and changes in several autoantibodies and cell adhesion molecules in patients with SLE. METHODS Stored sera collected at two or three clinic visits from each of 49 SLE patients (91% female, 59% African-American, 31% Caucasian, 10% other ethnicity, 38% under 30 years, 41% between 30-44 years, and 21% 45-63 years) were analyzed. The visits were chosen to include one visit with proteinuria, and one or two without, for each patient. Global disease activity was measured by the Physician's Global Assessment (PGA), SELENA-SLEDAI (SLE Disease Activity Index modified to exclude anti-dsDNA and complement) and renal activity assessed by urine protein (by urine dipstick) and Renal Activity Score. Sera were assayed for anti-C1q, anti-chromatin, anti-dsDNA, anti-ribosomal P, monocyte chemotactic protein-1 (MCP-1), vascular cell adhesion molecule (VCAM) intercellular adhesion molecule (ICAM) and complement. The associations between changes in disease activity and changes in biomarker levels were assessed. RESULTS In terms of global disease activity, anti-C1q had the highest association with the PGA (p = 0.09) and was strongly associated with modified SELENA-SLEDAI (p = 0.009). In terms of renal activity, anti-C1q had the highest association with proteinuria (p = 0.079), and was strongly associated with Renal Activity Score (p = 0.006). CONCLUSION Anti-C1q performed the best of the potential biomarkers, being significantly associated with the modified SELENA-SLEDAI and with the Renal Activity Score. This study indicates the potential superior utility of anti-C1q over anti-dsDNA and other measures to track renal activity.

Abstract
OBJECTIVE To summarize the state of knowledge regarding the economic burden of systemic lupus erythematosus (SLE) and to evaluate the quality of cost-of-illness (COI) studies conducted to date. METHODS Relevant literature was retrieved from the PubMed database in April 2010. The evaluation of identified articles was based on 7 key elements of COI studies derived from previous literature on health economics. Costs derived from each study were converted into 2008 US dollars using the Consumer Price Index and the purchasing power parity conversion rate. RESULTS A total of 11 articles were included in the evaluation. The average direct costs per patient-year ranged from $3,735-$14,410. Costs of inpatient care were found to be the largest component of direct costs in most of the studies. The employment rate varied from 35.8-55%. The average duration of annual short-term sick leave ranged from 7.0-64.8 days. The mean annual indirect costs per patient ranged from $1,093-$14,614, depending on the valuation method. CONCLUSION There is a substantial economic burden, in terms of health care resource utilization, associated with SLE, as well as losses of productivity due to work capacity impairment. The cost estimates in this review should be used with caution due to significant discrepancies in methodologies across studies. Future studies should address several methodologic considerations in order to measure the true costs related to SLE. Incidence-based COI studies are needed to evaluate the lifetime costs of SLE.

Abstract
OBJECTIVE To compare the healthcare cost and loss of productivity in patients with systemic lupus erythematosus (SLE) with (LN) and without lupus nephritis (lupus nephritis-negative, LNN). METHOD Patients were classified into those with active (ALN and ALNN) and inactive disease (ILN and ILNN). Patients reported on visits to healthcare professionals and use of diagnostic tests, medications, assistive devices, alternative treatments, hospital emergency visits, surgical procedures, and hospitalizations as well as loss of productivity in the 4 weeks preceding enrollment. RESULTS Enrollment was 141 patients, 79 with LN and 62 LNN. Patients with LN were more likely to visit rheumatologists and nephrologists, undergo diagnostic tests, and had higher costs for medications than patients who were LNN. The annual healthcare cost averaged $CAN 12,597 ± 9946 for patients with LN and $10,585 ± 13,149 for patients who were LNN, a difference of $2012 (95% CI -$2075, $6100). Patients with ALN had more diagnostic tests and surgical procedures, contributing to a significantly higher annual direct cost ($14,224 ± 10,265) compared to patients with ILN ($9142 ± 8419) and a difference of $5082 (95% CI $591, $9573). The healthcare cost was not different between patients with ALNN and patients with ILNN. In patients with LN and patients who were LNN, < 50% were employed and on average missed 6.5-9 days of work per month. The loss of productivity was significantly higher for caregivers of patients with LN than caregivers of patients who were LNN. CONCLUSION Healthcare cost and loss of productivity were similar between patients with LN and patients who were LNN; the loss of productivity for caregivers is higher for patients with LN; and the healthcare cost is greater in ALN than in ILN.

Abstract
Health outcomes and their measures used as end points in systemic lupus erythematosus (SLE) patient care and clinical trials have been varied and are still evolving. Although significant reductions in morbidity and mortality in SLE have been achieved, the medications approved for SLE have remained the same during the past 50 years. Despite the pressing need, aggressive advocacy in the community, and advances in drug development and testing in SLE, no medications have met US Food and Drug Administration guidelines for a new indication claim approval for SLE. This may be attributable to its multisystemic, remitting, and relapsing nature, and difficulty in identifying useful end points and appropriate tools to measure them. Thus, it is pivotal to identify and validate appropriate global, disease-specific, and perhaps organ-specific health outcomes for clinical research. This article reviews recent physician- and patient-generated health outcomes in SLE.

Abstract
There is growing interest in developing tools and methods for the surveillance of chronic rheumatic diseases, using existing resources such as administrative health databases. To illustrate how this might work, we used population-based administrative data to estimate and compare the prevalence of systemic autoimmune rheumatic diseases (SARDs) across three Canadian provinces, assessing for regional differences and the effects of demographic factors. Cases of SARDs (systemic lupus erythematosus, scleroderma, primary Sjogren's, polymyositis/dermatomyositis) were ascertained from provincial physician billing and hospitalization data. We combined information from three case definitions, using hierarchical Bayesian latent class regression models that account for the imperfect nature of each case definition. Using methods that account for the imperfect nature of both billing and hospitalization databases, we estimated the over-all prevalence of SARDs to be approximately 2-3 cases per 1,000 residents. Stratified prevalence estimates suggested similar demographic trends across provinces (i.e. greater prevalence in females-versus-males, and in persons of older age). The prevalence in older females approached or exceeded 1 in 100, which may reflect the high burden of primary Sjogren's syndrome in this group. Adjusting for demographics, there was a greater prevalence in urban-versus-rural settings. In our work, prevalence estimates had good face validity and provided useful information about potential regional and demographic variations. Our results suggest that surveillance of some rheumatic diseases using administrative data may indeed be feasible. Our work highlights the usefulness of using multiple data sources, adjusting for the error in each.
