Lupus nephritis and socioeconomic status: Findings from the Southern California lupus registry.

OBJECTIVE: Lupus nephritis (LN) is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Despite multiple studies addressing healthcare disparities, disparate outcomes in LN persist. We investigate herein the association between socioeconomic status (SES) and LN as well as the association between SES, SLE disease activity index (SLEDAI), and treatment response. METHODS: Patients were selected from the Southern California Lupus Registry (SCOLR), a registry enrolling all-comers with SLE. Analysis was completed on individuals with public vs. private insurance. Insurance and ethnicity were used as surrogate variables for SES, and we tested differences in means. RESULTS: After adjusting for age and sex, public insurance was independently associated with the prevalence of LN. Analysis of 35 patients revealed greater proteinuria and mean SLEDAI in patients with public insurance at baseline and 6 months. Baseline, 6-, and 12-month SLEDAI means were significantly lower in Asian/Pacific Islanders (PI) compared to others. While non-Hispanic Whites demonstrated mean SLEDAI improvement over 6 months, Asians/PI, Blacks, and Hispanics demonstrated worsened disease activity on average. CONCLUSION: Low SES, when defined by insurance, is associated with greater adverse outcomes in SLE. This is the first regional study that compares differences in treatment response in LN patients with low SES as well as association of SES with long-term outcomes in SLE and LN in southern California.

Cardiovascular disease and bone health in aging female rheumatic disease populations: A review.

Rheumatic diseases cover a wide spectrum of conditions, including primary and secondary degenerative joint diseases and autoimmune inflammatory rheumatic diseases. The risks of cardiovascular disease and osteoporosis and resultant fractures in aging female rheumatic disease populations, especially those with autoimmune rheumatic diseases, are increased. Changes in the immune system in aging populations need to be considered especially among patients with autoimmune rheumatic diseases. Immunosenescence is closely aligned to reduced adaptive immunity and increased non-specific innate immunity leading to chronic inflammation of inflammaging. The effective use of disease-modifying antirheumatic drugs to control autoimmune rheumatic diseases may also mitigate factors leading to cardiovascular disease and osteoporosis. Rheumatic diseases, which largely manifest as arthritis, predispose patients to premature joint degeneration and poor bone health and therefore have a higher risk of developing end-stage arthritis requiring joint arthroplasties sooner or more often than other patients without rheumatic disease.

Systemic lupus erythematous readmissions have reduced: a 9-year longitudinal study of the nationwide readmission database.

BACKGROUND: Longitudinal data on the trends in systemic lupus erythematous (SLE) readmissions are limited. We aimed to study trends in 30-day readmissions of patients admitted for SLE flares and all SLE hospitalizations in the USA from 2010 to 2018. MATERIALS AND METHODS: Data were obtained from the nationwide readmission database (NRD). We performed a retrospective 9-year longitudinal trend analysis using the 2010-2018 NRD databases. We searched for index hospitalizations of adult patients diagnosed with SLE using the International Classification of Diseases (ICD) codes. Elective and traumatic readmissions were excluded from the study. Multivariable logistic and linear regression analyses were used to calculate the adjusted p value trend for categorical and continuous outcomes, respectively. RESULTS: The 30-day readmissions following index admissions of all SLE patients and for SLE flares decreased from 15.6% in 2010 to 13.3% in 2018 (adjusted p trend < 0.0001), and 20.3% in 2010 to 17.6% in 2018 (adjusted p trend = 0.009) respectively. Following SLE-flare admissions, hospital length of stay (LOS) decreased from 6.7 to 6 days (adjusted p trend = 0.045), while the proportion with a Charlson comorbidity index (CCI) score ≥ 3 increased from 42.2 to 54.4% (adjusted p trend < 0.0001) during the study period. SLE and its organ involvement, sepsis, and infections were common reasons for 30-day readmissions. CONCLUSION: About 1 in 5 SLE-flare admissions resulted in a 30-day readmission. The 30-day readmissions following index hospitalization for SLE flares and all SLE hospitalizations have decreased in the last decade. Although the readmission LOS was reduced, the CCI score increased over time. Key Points • The 30-day readmissions following index hospitalization for SLE flares and all SLE hospitalizations have reduced in the last decade although the CCI score increased over time. • SLE, its organ involvement, and infections are common reasons for readmission. • Infection control strategies, optimal management of SLE and its complications, and emphasis on an ideal transition of care are essential in reducing SLE readmissions.

The impact of clinical pharmacist integration in a community rheumatology clinic.

PURPOSE: To describe the benefits of pharmacist integration into a community rheumatology clinic in terms of clinical outcomes, patient and provider satisfaction, and clinic time efficiency. METHODS: A 6-month study was conducted at a community rheumatology clinic to compare clinical and patient and provider satisfaction outcomes before and after a clinical pharmacist (CP) was integrated into the clinic staff to assist with providing medication counseling, ordering and monitoring laboratory tests, monitoring adverse effects and medication adherence, and titrating medication doses. The primary outcome was the change in Routine Assessment of Patient Index Data 3 (RAPID-3) scores from baseline to 3 and 6 months after CP integration. Secondary outcomes included the change in monthly pain scores from baseline to 6 months, the change in patient satisfaction scores from baseline to 6 months, and time saved for the rheumatology providers after pharmacist integration into the clinic. RESULTS: The mean difference in RAPID-3 scores from baseline to 3 months (N = 55) was an improvement of 5.58 points (P < 0.001), while the mean change in weighted RAPID-3 scores was an improvement of 1.87 (P < 0.001). The mean change in RAPID-3 scores from baseline to 6 months (n = 25) was an improvement of 5.13 (P = 0.003), and the mean change in weighted RAPID-3 scores was 1.78 (P = 0.003). CONCLUSION: The results of this quality improvement project suggest that the integration of a CP in the rheumatology clinic improved patient-reported outcomes, as quantified by patients' pain scores and RAPID-3 scores. The integration of the CP also appeared to enhance patient and provider satisfaction.

Longitudinal trends of systemic lupus erythematous hospitalizations in the United States: a two-decade population-based study.

BACKGROUND: Longitudinal data are limited on systemic lupus erythematosus (SLE) hospitalizations. We aim to study longitudinal trends of SLE hospitalizations in the last 2 decades in the United States (U.S). METHODS: Data were obtained from the National Inpatient Sample database (NIS). We performed a 21-year longitudinal trend analysis of NIS 1998-2018. We searched for hospitalizations for adult patients with a "principal" diagnosis of SLE (SLE flare group) and those with "any" diagnosis of SLE (all SLE hospitalization group) using ICD codes. All non-SLE hospitalizations for adult patients were used as the control. Multivariable logistic and linear regression were used appropriately to calculate adjusted p-trend for the outcomes of interest. RESULTS: Incidence of SLE flare hospitalization reduced from 4.1 to 3.2 per 100,000 U.S persons from 1998 to 2018 (adjusted p-trend < 0.0001). The proportion of all hospitalized patients with SLE admitted principally for SLE reduced from 11.3% in 1998 to 5.7% in 2018 (adjusted p-tend < 0.0001). The proportion of hospitalized blacks in the SLE flare and all SLE hospitalization groups increased from 37.7% and 26.9% in 1998 to 44.7% and 30.7% in 2018 respectively (adjusted p-trend < 0.0001). The proportion of hospitalized Hispanics and Asians disproportionally increased in SLE flare hospitalizations compared to the control group. CONCLUSION: The incidence of hospitalization for SLE flare has reduced in the last 2 decades in the U.S. The proportion of hospitalized patients with SLE admitted principally for SLE has reduced significantly over time. However, the burden of SLE hospitalizations among ethnic minorities has increased over time. Key Points • The incidence of hospitalization for SLE flare has reduced in the last 2 decades in the U.S. • The proportion of hospitalized patients with SLE admitted principally for SLE has reduced significantly over time. • The burden of SLE hospitalizations among ethnic minorities such as blacks has increased over time.

Barriers to Enrollment in Rheumatology Research: Who, What, Where, When, and Why?

Despite the evidence that complicated rheumatic diseases are more prevalent and severe in ethnic minorities, rheumatology research is afflicted with inadequate patient representation. It is lacking in ethnic and socioeconomic diversity. The objective of this study is to identify barriers to enrollment in rheumatology research and propose possible solutions to overcome these barriers. In this study, 184 patients from two rheumatology clinics (Safety Net clinic, a university-based clinic) were surveyed for concerns regarding participation in clinical research. Patients were asked to rank their top five of eight concerns. Data were then stratified by self-reported ethnicity and clinic site to determine ranking differences in both groups. Fear of risks associated with clinical research was ranked as the primary barrier in all ethnicities. More non-Hispanic Whites (NHW) (24.4%) ranked work responsibilities as a primary barrier compared to Hispanics (10%). Fear of discovering a serious illness as a primary barrier was more frequent at the Safety Net clinic (25%) compared to the university-based clinic (6.3%) and ranked more frequently in the top five in Hispanics compared to NHW. Fears associated with research risks, work responsibilities, and fear of discovering a serious illness were the top-ranked barriers to enrollment in research among patients. However, differences in rankings between ethnicities and clinic sites were identified. This sheds light on the importance of health literacy and the responsibility of researchers in addressing gaps in communication while acknowledging potential cultural components that warrant further investigation.

Chemosis as an Initial Presentation of Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) can present in a multitude of ways, which can be confounding and misleading for a clinician. Chemosis as an initial presentation is rare and has only been documented on a few case reports. However, when present, simultaneous involvement of other organs is likely. We present a previously healthy 29-year-old male who presented with severe bilateral chemosis and was subsequently diagnosed with SLE and antiphospholipid syndrome. Complications included multiple acute cerebral infarcts, lupus psychosis, lupus pleuritis, and lupus nephritis. The patient recovered well with appropriate treatment and chemosis ultimately resolved. Recognizing chemosis as an initial presentation of SLE is vital for appropriate evaluation and timely treatment to prevent disease progression.

Vitamin D and Lupus: Are we doing enough?

The aim of this study is to identify rheumatology practice care gaps in evaluating for vitamin D deficiency in systemic lupus erythematosus (SLE), as well as adherence to vitamin D replacement in SLE patients currently on corticosteroid therapy. Data for this study were collected from the Southern California Lupus Registry in addition to data extraction from medical health records. Evaluation of serum vitamin D level within 6 months of patient encounter, current or prior use of systemic corticosteroids, and vitamin D replacement in patients receiving corticosteroid therapy were noted. Vitamin D deficiency was defined as serum 25(OH)D3 less than 30 ng/ml. Of 182 patients in the cohort, data were available for 176. Evaluation of vitamin D deficiency was noted in 49 patients (28%), 27 (55%) of whom had abnormal values. Current corticosteroid use was noted in 56 (32%) patients and prior use in 73 (41%). Vitamin D replacement was prescribed to 30 (54%) patients with current corticosteroid use. In an academic rheumatology clinic, we have identified underevaluation for vitamin D deficiency in SLE patients despite increasing awareness of its contribution to disease activity. Further, routine supplementation of vitamin D is particularly lacking in individuals receiving systemic corticosteroids. This presents a practical opportunity for improvement in SLE clinical care.

The Southern California Lupus Registry: I. Baseline characteristics of lupus patients in uncharted territory.

OBJECTIVE: This study aimed to determine the baseline characteristics of a multi-ethnic systemic lupus erythematosus (SLE) cohort in Southern California established with the intent of addressing regional health inequity. METHODS: Patients ≥18 years of age with SLE per the Systemic Lupus International Collaborating Clinics (SLICC) criteria were recruited into the Southern California Lupus Registry (SCOLR) if they resided in San Bernardino and Riverside counties in California. Individuals were categorized according to their stated ethnicity as non-Hispanic White, Hispanic, Black, or Asian. Descriptive statistics were utilized for analysis. Predictors of renal disease were assessed by binomial regression. RESULTS: The SCOLR cohort comprised 162 patients: 57 non-Hispanic White, 58 Hispanic, 17 Asian, and 30 Black. A difference in the rate of renal involvement and SLE duration was found among the four ethnic groups. Renal involvement was significantly higher in Hispanics compared with non-Hispanic Whites. CONCLUSION: In line with other cohorts, this study shows greater renal involvement in Hispanics than non-Hispanic Whites, demonstrating a need for more aggressive screening and early intervention to improve long-term outcomes. As a multi-ethnic SLE cohort, the SCOLR serves as a foundation for longitudinal studies addressing health inequity in this region.

Five-Year Follow-Up of Coronary Microvascular Dysfunction and Coronary Artery Disease in Systemic Lupus Erythematosus: Results From a Community-Based Lupus Cohort.

OBJECTIVE: The present study was undertaken to investigate prospective change in the prevalence of coronary microvascular dysfunction (CMD) and obstructive coronary artery disease (CAD) in a cohort of subjects with systemic lupus erythematosus (SLE) initially evaluated for anginal chest pain (CP). Prior work documented a relatively high prevalence of CMD in the absence of obstructive CAD in subjects with SLE. METHODS: Twenty female SLE subjects with CP who underwent stress cardiac magnetic resonance imaging (CMRI) and coronary computed tomography angiography at baseline were reevaluated at 5 years. RESULTS: Seventeen subjects (85%) were available and reenrolled, of which 11 (65%) had persistent CP at follow-up. Fourteen subjects had complete follow-up CMRI, of which 36% (n = 5) demonstrated CMD at follow-up. Further, 25% (1 of 4) of the originally abnormal myocardial perfusion reserve index (MPRI) findings at baseline were lower at follow-up, while 2 additional abnormal MPRI findings at follow-up were noted in previously normal MPRI results. The prevalence of CMD and nonobstructive/obstructive CAD both was unchanged between baseline and follow-up, respectively (both P values not significant). During follow-up, 33% of subjects (5 of 15) had adverse cardiac outcomes, including pericarditis, unstable angina, or intracranial aneurysm clipping procedure. CONCLUSION: At the 5-year follow-up of SLE subjects with CP who were evaluated at baseline and follow-up, a majority had persistent CP, and nearly one-half had similar or worse myocardial perfusion consistent with CMD without obstructive CAD. These findings propose an alternative explanation for CP in SLE subjects compared to the more common SLE-related accelerated obstructive CAD accounting for CP and adverse outcomes. These findings support further studies of CMD as an etiology for cardiac morbidity and mortality in SLE.

Underserved Communities: Enhancing Care with Graduate Medical Education.

The shortage of health care professionals is projected to worsen in the coming years. This is particularly concerning in underserved areas that are fraught with disparities in disease outcomes and life expectancy, quality of life, and health care access. The onus is on medical education institutions to train students to serve vulnerable communities to improve both health care access and the quality of medical school education. When health disparities are formally included in medical education curricula and the culture of medical education shifts to a community-based learning approach, patients and health care providers alike will reap the benefits.

Healthcare disparities in rheumatology: the role of education at a global level.

All fields of medicine are victim to health inequity worldwide, including rheumatology. While the health system is a key proponent to health access for all, other social determinants of health also impact world health. We describe herein the current state of global healthcare disparities in rheumatology and attempts at optimizing graduate medical education and resources for optimized healthcare, international research collaborations and a future of universal health equity. We performed a comprehensive search through Pubmed using the following keywords: healthcare disparities, medical education, access to care, community health.Key Points• Healthcare disparities are ubiquitous globally, including the field of rheumatology.• The heterogeneity of global healthcare disparities emphasizes the importance of addressing unmet needs at a regional level.• A standardized approach to incorporating healthcare disparities education in the medical field is lacking. Intervening at this level provides a foundation of increasing provider awareness of regional healthcare disparities so as to establish a framework of addressing such disparities in a culturally competent manner.

Atypical manifestations of sarcoidosis in a Hispanic male.

Sarcoidosis is a multisystem granulomatous disease of unknown etiology that can present with nonspecific features, often resulting in delayed diagnosis. The diagnosis requires the demonstration of non-caseating granulomas on biopsy. While the prevalence of sarcoidosis in the USA is rare, the disease is rarer yet in Hispanics. It is for this reason that we report herein the case of a Hispanic gentleman with a unique clinical manifestations of sarcoidosis. With what began as a two-month history of joint pain and skin rash, this 55-year-old man was hospitalized with multiple joint pain, weight loss, fatigue and a pruritic rash with leonine facies in the setting of anemia, leukopenia, hypercalcemia, elevated serum creatinine, and urine Bence-Jones proteinuria. CT imaging of the chest was nonspecific, but skin biopsy revealed non-caseating granulomatous disease. After completing an infectious and malignancy evaluation, the patient was diagnosed with sarcoidosis, which was treated successfully with low-dose steroid therapy.

A case report of heart transplant for ischaemic cardiomyopathy from lupus coronary vasculitis.

BACKGROUND: Coronary vasculitis is a rare, life-threatening complication of systemic lupus erythematosus (SLE). CASE SUMMARY: A 23-year-old woman with SLE presented with typical angina and worsening dyspnoea on exertion. Coronary angiography revealed severe triple vessel disease with a 'string of beads' appearance classic for coronary vasculitis. Transthoracic echocardiogram revealed ejection fraction of 25-30% with a severely hypokinetic distal septum and distal anterior wall and an akinetic apical wall. Despite vasculitis treatment with cyclophosphamide and pulse-dose steroids, her coronary vasculitis did not improve. She was refractory to anti-anginal and guideline-directed medical therapy for heart failure and successfully underwent orthotopic heart transplant (OHT). DISCUSSION: This is the first reported case of OHT in the case of SLE coronary vasculitis. Chronic SLE coronary vasculitis is caused by lymphocyic infiltration leading to inflammation and fibrosis of the major epicardial coronary arteries but can be successfully managed with OHT when refractory to medical SLE and heart failure therapies. It can affect patients of all ages with SLE, emphasizing the importance of thorough history taking and clinical evaluation in young patients presenting with cardiac symptoms to establish an appropriate diagnosis and treatment plan.

The impact of obesity on SLE disease activity: findings from the Southern California Lupus Registry (SCOLR).

The role of obesity in systemic lupus erythematosus (SLE) remains controversial. Studies have linked adiposity with a heightened risk of clinical complications including neurocognitive decline, renal impairment, dampened physical activity, and depressed quality of life-but not disease activity. We aimed to reexamine whether obesity in SLE patients independently associates with higher disease activity. Adult patients with SLE were recruited from the longitudinal, multi-ethnic Southern California Lupus Registry (SCOLR). Disease status was ascertained by calculating SLE Disease Activity Index (SLEDAI), which was then statistically analyzed for association with increased body mass index (BMI) by univariable and multivariable regression analyses. One hundred and thirty-seven patients were included in the study; 37% were obese (BMI ≥ 30 kg/m2). Obesity was significantly associated with SLEDAI (P = 0.026) and current steroid use (P = 0.029). Multivariable regression analysis demonstrated that obesity remained independently associated with lupus activity (OR 2.335, P = 0.026). In a representative sample of patients with SLE, obesity independently associated with worse SLE disease activity. Obesity may therefore be an important target for improving SLE outcomes.

Dilemma in management: a patient with active systemic lupus erythematosus presenting with pulmonary cavitary lesion.

Pulmonary manifestations of systemic lupus erythematosus (SLE) include, but are not limited to, pneumonia, interstitial pneumonitis, atelectasis and pleural effusion. Cavitary lung lesions are rarely associated with SLE. We present herein the case of a female patient with SLE and lupus nephritis who presented to the hospital with respiratory failure, rash and arthralgias. She was found to have a cavitary lung lesion most concerning for infection. However, despite an extensive inpatient antibiotic course, her symptoms persisted. After a collaborative effort between the primary team, pulmonology, infectious disease and rheumatology, she was placed on systemic glucocorticoid therapy, which resolved not only her respiratory failure, but also her cavitary lung lesion on subsequent follow-up with imaging. The dilemma of management in such cases will be discussed in addition to a review of previously reported cases.
