Association of Childhood Abuse with Incident Systemic Lupus Erythematosus in Adulthood in a Longitudinal Cohort of Women

Positive psychosocial factors may protect against perceived stress in people with systemic lupus erythematosus with and without trauma history

OBJECTIVE

Trauma history is associated with SLE onset and worse patient-reported outcomes; perceived stress is associated with greater SLE disease activity. Stress perceptions vary in response to life events and may be influenced by psychosocial factors. In an SLE cohort, we examined whether stressful events associated with perceived stress, whether psychosocial factors affected perceived stress, and whether these relationships varied by prior trauma exposure.

METHODS

This is a cross-sectional analysis of data from the California Lupus Epidemiology Study, an adult SLE cohort. Multivariable linear regression analyses controlling for age, gender, educational attainment, income, SLE damage, comorbid conditions, glucocorticoids ≥7.5 mg/day and depression examined associations of recent stressful events (Life Events Inventory) and positive (resilience, self-efficacy, emotional support) and negative (social isolation) psychosocial factors with perceived stress. Analyses were stratified by lifetime trauma history (Brief Trauma Questionnaire (BTQ)) and by adverse childhood experiences (ACEs) in a subset.

RESULTS

Among 242 individuals with SLE, a greater number of recent stressful events was associated with greater perceived stress (beta (95% CI)=0.20 (0.07 to 0.33), p=0.003). Positive psychosocial factor score representing resilience, self-efficacy and emotional support was associated with lower perceived stress when accounting for number of stressful events (-0.67 (-0.94 to -0.40), p<0.0001); social isolation was associated with higher stress (0.20 (0.14 to 0.25), p<0.0001). In analyses stratified by BTQ trauma and ACEs, associations of psychosocial factors and perceived stress were similar between groups. However, the number of recent stressful events was significantly associated with perceived stress only for people with BTQ trauma (0.17 (0.05 to 0.29), p=0.0077) and ACEs (0.37 (0.15 to 0.58), p=0.0011).

CONCLUSION

Enhancing positive and lessening negative psychosocial factors may mitigate deleterious perceived stress, which may improve outcomes in SLE, even among individuals with a history of prior trauma who may be more vulnerable to recent stressful events.

Childhood adverse experiences and clinical manifestations in women with systemic lupus erythematosus

BACKGROUND

Patients with a history of adverse childhood experiences (ACEs) have a higher incidence of developing autoimmune diseases such as systemic lupus erythematosus.

OBJECTIVE

The objective is to associate the ACE with the clinical manifestations of SLE in adult women.

METHODS

This is a cross-sectional observational analytical study in a sample of women diagnosed with SLE, whose data were collected through interviews and a review of medical records. The ACE were identified using the Childhood Trauma Questionnaire (CTQ) and were associated with sociodemographic and clinical data, as well as the presence of harm.

RESULTS

The sample was composed of 97 women. In this study, significant associations were found between physical abuse and oral ulcers (p = .006) and nephritis (p = .032); between sexual abuse and Sjogren's syndrome (p = .024) and oral ulcers (p = .035); between physical neglect and photosensitivity (p = .024) and oral ulcers (p = .039); and between emotional neglect and diabetes mellitus (p = .033).

CONCLUSION

Individuals with a positive history of ACE have significant associations with certain clinical manifestations of SLE and subtypes of ACE, underscoring the importance of preventing childhood trauma to improve adult health. Further studies are needed to elucidate the impact of ACE on adult health.

Systemic lupus erythematosus in American Indian/Alaska natives: Incorporating our new understanding of the biology of trauma

OBJECTIVE

To review the literature regarding systemic lupus erythematosus (SLE) in American Indian/Alaska Native (AI/AN) people and relate prevalence and/or disease severity to our emerging understanding of the biology of trauma and toxic stress.

METHODS

We conducted a search and review of the literature using search terms "lupus and American Indians" "ACEs and disease outcome" "Biology of Adversity" "lupus and ACE scores," " lupus and childhood abuse." These search criteria were entered into Google Scholar and articles retrieved from PubMed, NBCI. This approach yielded a small numbers of papers used throughout this review. We excluded articles that were not published in a peer reviewed journals, as well as editorial commentaries.

RESULTS

In the AI/AN population, SLE shows high prevalence rates and severe disease manifestations, comparable to the African American population. AI/AN populations also have high rates of childhood trauma. Toxic stress and trauma such as those catalogued in the Adverse Childhood Experiences (ACE) study have broad-reaching immunologic and epigenetic effects that are likely to be relevant to our understanding of SLE in AI/AN people.

CONCLUSIONS

AI/AN people have high rates of SLE. These high rates are likely to be driven by many complex factors, not all of which are genetic. Future research is needed to establish (or refute) a causal connection between the biology of adversity and SLE in socially marginalized and historically traumatized populations.

Disparities in Lupus and the Role of Social Determinants of Health: Current State of Knowledge and Directions for Future Research

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The complex relationships between race and ethnicity and social determinants of health (SDOH) in influencing SLE and its course are increasingly appreciated. Multiple SDOH have been strongly associated with lupus incidence and outcomes and contribute to health disparities in lupus. Measures of socioeconomic status, including economic instability, poverty, unemployment, and food insecurity, as well as features of the neighborhood and built environment, including lack of safe and affordable housing, crime, stress, racial segregation, and discrimination, are associated with race and ethnicity in the US and are risk factors for poor outcomes in lupus. In this scientific statement, we aimed to summarize current evidence on the role of SDOH in relation to racial and ethnic disparities in SLE and SLE outcomes, primarily as experienced in the U.S. Lupus Foundation of America's Health Disparities Advisory Panel, comprising 10 health disparity experts, including academic researchers and patients, who met 12 times over the course of 18 months in assembling and reviewing the data for this study. Sources included articles published from 2011 to 2023 in PubMed, Centers for Disease Control and Prevention data, and bibliographies and recommendations. Search terms included lupus, race, ethnicity, and SDOH domains. Data were extracted and synthesized into this scientific statement. Poorer neighborhoods correlate with increased damage, reduced care, and stress-induced lupus flares. Large disparities in health care affordability, accessibility, and acceptability exist in the US, varying by region, insurance status, and racial and minority groups. Preliminary interventions targeted social support, depression, and shared-decision-making, but more research and intervention implementation and evaluation are needed. Disparities in lupus across racial and ethnic groups in the US are driven by SDOH, some of which are more easily remediable than others. A multidimensional and multidisciplinary approach involving various stakeholder groups is needed to address these complex challenges, address these diminish disparities, and improve outcomes.

The association of trauma with self-reported flares and disease activity in systemic lupus erythematosus (SLE)

OBJECTIVES

Trauma has been linked to incident SLE, but its relationship with SLE disease activity is unknown. This analysis examines associations between trauma exposures and patient-reported SLE disease activity and flares.

METHODS

Data were from the California Lupus Epidemiology Study (CLUES). Flares were self-reported as any flare and, of those, flares accompanied by medical care (hospitalization or physician contact). The Systemic Lupus Activity Questionnaire (SLAQ) assessed disease activity. The Brief Trauma Questionnaire (BTQ) assessed all historical trauma exposures. The Adverse Childhood Experiences (ACEs) questionnaire was available for a subset. Multivariable regression analyses (n = 252) examined whether trauma exposure was associated with flares or SLAQ controlling for age, sex, poverty, race/ethnicity, comorbidities, perceived stress, disease duration and self-reported disease damage.

RESULTS

Excluding exposure to serious illness, 63.4% reported ≥1 trauma exposure. Any traumatic event, excluding illness, doubled the odds of a flare [OR 2.27 (95% CI 1.24, 4.17)] and was associated with significantly higher SLAQ scores [β 2.31 (0.86, 3.76)]. Adjusted odds of any flare and flare with medical care were significantly elevated for those with both BTQ and ACE exposures [5.91 (2.21, 15.82) and 4.69 (1.56, 14.07), respectively]. SLAQ scores were also higher for those with both exposures [β 5.22 (3.00, 7.44)].

CONCLUSION

In this cohort, those with a history of trauma reported more flares and greater disease activity. Identifying mechanisms of associations between trauma and disease activity and flares, as well as interventions to mitigate the effects of trauma exposures is critical, given the high rates of trauma exposures.

The link between post-traumatic stress disorder and systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a heterogeneous, multisystem autoimmune disorder characterized by unpredictable disease flares. Although the pathogenesis of SLE is complex, an epidemiologic link between posttraumatic stress disorder (PTSD) and the development of SLE has been identified, suggesting that stress-related disorders alter the susceptibility to SLE. Despite the strong epidemiologic evidence connecting PTSD and SLE, gaps remain in our understanding of how the two may be connected. Perturbations in the autonomic nervous system, neuroendocrine system, and at the genomic level may cause and sustain immune dysregulation that could lower the threshold for the development and propagation of SLE. We first describe shared risk factors for SLE and PTSD. We then describe potential biological pathways which may facilitate excessive inflammation in the context of PTSD. Among those genetically predisposed to SLE, systemic inflammation that accompanies chronic stress may fan the flames of smoldering SLE by priming immune pathways. Further studies on the connection between trauma and inflammation will provide important data on pathogenesis, risk factors, and novel treatments for SLE.

Post-traumatic stress disorder in patients with systemic lupus erythematosus heavily affects quality of life. A cross-sectional web survey-based study

OBJECTIVES

Neuropsychiatric symptoms develop in up to 20% of the patients with Systemic Lupus Erythematosus (SLE). Growing evidence is accruing on the association of SLE with Post-traumatic Stress Disorder (PTSD), but little is known about its contribution on patient-reported outcomes. This study focuses on PTSD prevalence in our SLE cohort and on its impact on quality of life.

METHODS

Trauma and Loss Spectrum - Self Reported (TALS-SR) and Lupus Quality of Life (Lupus QoL) questionnaires were administered via web to the patients with SLE in our cohort, along with questions on demographical and disease-related aspects.

RESULTS

Among 99 patients who completed the questionnaire, fatigue prevalence was 75% and 31% scored TALS-SR test consistently with PTSD. Patients with PTSD achieved lower scores compared to those without PTSD in three Lupus QoL domains: planning (83.3 vs. 100, p = .035), body image (85.0 vs. 95.0, p = .031) and fatigue (66.7 vs. 91.7, p = .001). An inverse correlation was found between TALS-SR domains and Lupus QoL scores, particularly regarding fatigue with reaction to losses or upsetting events (ρ -0.458, p < .001).

CONCLUSIONS

PTSD is possibly far more frequent in patients with SLE than in general population and exerts a detrimental influence on quality of life.

Childhood maltreatment is not associated with atopic dermatitis in adults: results from a cross-sectional population-based cohort study

BACKGROUND

Childhood maltreatment (CM) is related to poor physical and mental health outcomes in adults. Knowledge on the impact of CM on skin diseases is limited, and no study has previously addressed the association of CM with atopic dermatitis (AD) in adult age.

OBJECTIVES

To analyze the prevalence of CM in individuals with physician-diagnosed AD, and to examine the relationship between different types of CM with physician-diagnosed AD in a general population sample of German adults.

METHODS

Data from 2973 participants from the cross-sectional population-based Study of Health in Pomerania (SHIP) TREND-0 were analyzed (aged 20 to 83 years; 51.4% female). We administered the Childhood Trauma Questionnaire (CTQ) assessing emotional, physical and sexual abuse, and emotional and physical neglect. AD was diagnosed by dermatologists in a standardized clinical examination. We conducted logistic regression analyses adjusted for age, sex and school education to investigate the association of CM types with AD.

RESULTS

Among all individuals with AD, 20.6% reported to have experienced at least one type of moderate or severe CM. Emotional and physical neglect were the most frequently reported CM types. Overall, the prevalence of CM types among individuals with AD did not differ from those among individuals without AD. We found no association of CM type with AD.

CONCLUSIONS

This is the first study investigating the association of CM with AD in adults. CM was common in the present general population sample, emphasizing that CM is an important public health problem. Our findings suggest that CM is not a risk factor for AD. It might be hypothesized that AD severity is a crucial outcome, and that CM history is a factor with impact on disease severity and course rather than a risk factor for the development of AD. Longitudinal studies are required to address this question.

Understanding the Concept of Pre-Clinical Autoimmunity: Prediction and Prevention of Systemic Lupus Erythematosus: Identifying Risk Factors and Developing Strategies Against Disease Development

There is growing evidence that preceding the diagnosis or classification of systemic lupus erythematosus (SLE), patients undergo a preclinical phase of disease where markers of inflammation and autoimmunity are already present. Not surprisingly then, even though SLE management has improved over the years, many patients will already have irreversible disease-related organ damage by time they have been diagnosed with SLE. By gaining a greater understanding of the pathogenesis of preclinical SLE, we can potentially identify patients earlier in the disease course who are at-risk of transitioning to full-blown SLE and implement preventative strategies. In this review, we discuss the current state of knowledge of SLE preclinical pathogenesis and propose a screening and preventative strategy that involves the use of promising biomarkers of early disease, modification of lifestyle and environmental risk factors, and initiation of preventative therapies, as examined in other autoimmune diseases such as rheumatoid arthritis and type 1 diabetes.

A Systematic Review of Research on Trauma and Women's Health in the Nurses' Health Study II

OBJECTIVE

To synthesize research on interpersonal trauma and women's health from the Nurses' Health Study II (NHS II) and to analyze conceptualization of interpersonal trauma across studies.

DATA SOURCES

A literature review was conducted in PubMed using a systematic search strategy.

STUDY SELECTION

Articles were included in the review if they used data from the NHS II and involved investigations of interpersonal trauma. Theoretical articles, methodologic articles, and other literature reviews involving the NHS II were excluded. Initially, the search returned 61 articles. After exclusions, 45 articles met the criteria for inclusion in the review and data extraction.

DATA EXTRACTION

Information was extracted and consolidated in an evidence table. Data included study time frame, sample, definition of trauma, outcomes studied, and journal of publication.

DATA SYNTHESIS

Trauma was not operationalized consistently across studies, even though the NHS II assessed trauma experiences in childhood, adolescence, and adulthood. Most investigations focused on childhood abuse, with investigations of childhood sexual abuse overrepresented in comparison to other abuse experiences. Authors conducting studies of trauma at any time in the life course consistently found a negative association with physical and mental health outcomes, which were increased by the presence of posttraumatic stress symptoms. Results from a small number of studies suggested a negative intergenerational impact of trauma on the children of women in the NHS II.

CONCLUSION

Interpersonal trauma across the life course was strongly associated with many leading causes of morbidity and mortality among female nurses. Trauma conceptualization and operationalization varied across studies, and future investigations should leverage the full range of trauma measures available in the NHS II data set.

Case-control study of adverse childhood experiences and multiple sclerosis risk and clinical outcomes

Background

Adverse childhood experiences (ACEs) are linked to numerous health conditions but understudied in multiple sclerosis (MS). This study’s objective was to test for the association between ACEs and MS risk and several clinical outcomes.

Methods

We used a sample of adult, non-Hispanic MS cases (n = 1422) and controls (n = 1185) from Northern California. Eighteen ACEs were assessed including parent divorce, parent death, and abuse. Outcomes included MS risk, age of MS onset, Multiple Sclerosis Severity Scale score, and use of a walking aid. Logistic and linear regression estimated odds ratios (ORs) (and beta coefficients) and 95% confidence intervals (CIs) for ACEs operationalized as any/none, counts, individual events, and latent factors/patterns.

Results

Overall, more MS cases experienced ≥1 ACE compared to controls (54.5% and 53.8%, respectively). After adjusting for sex, birthyear, and race, this small difference was attenuated (OR = 1.01, 95% CI: 0.87, 1.18). There were no trends of increasing or decreasing odds of MS across ACE count categories. Consistent associations between individual ACEs between ages 0–10 and 11–20 years and MS risk were not detected. Factor analysis identified five latent ACE factors, but their associations with MS risk were approximately null. Age of MS onset and other clinical outcomes were not associated with ACEs after multiple testing correction.

Conclusion

Despite rich data and multiple approaches to operationalizing ACEs, no consistent and statistically significant effects were observed between ACEs with MS. This highlights the challenges of studying sensitive, retrospective events among adults that occurred decades before data collection.

Using Microbiome-Based Approaches to Deprogram Chronic Disorders and Extend the Healthspan following Adverse Childhood Experiences

Adverse childhood experiences (ACEs), which can include child trafficking, are known to program children for disrupted biological cycles, premature aging, microbiome dysbiosis, immune-inflammatory misregulation, and chronic disease multimorbidity. To date, the microbiome has not been a major focus of deprogramming efforts despite its emerging role in every aspect of ACE-related dysbiosis and dysfunction. This article examines: (1) the utility of incorporating microorganism-based, anti-aging approaches to combat ACE-programmed chronic diseases (also known as noncommunicable diseases and conditions, NCDs) and (2) microbiome regulation of core systems biology cycles that affect NCD comorbid risk. In this review, microbiota influence over three key cyclic rhythms (circadian cycles, the sleep cycle, and the lifespan/longevity cycle) as well as tissue inflammation and oxidative stress are discussed as an opportunity to deprogram ACE-driven chronic disorders. Microbiota, particularly those in the gut, have been shown to affect host–microbe interactions regulating the circadian clock, sleep quality, as well as immune function/senescence, and regulation of tissue inflammation. The microimmunosome is one of several systems biology targets of gut microbiota regulation. Furthermore, correcting misregulated inflammation and increased oxidative stress is key to protecting telomere length and lifespan/longevity and extending what has become known as the healthspan. This review article concludes that to reverse the tragedy of ACE-programmed NCDs and premature aging, managing the human holobiont microbiome should become a routine part of healthcare and preventative medicine across the life course.

Childhood Maltreatment and Psychiatric Comorbidity in Immune-Mediated Inflammatory Disorders

OBJECTIVE

To determine whether childhood maltreatment is associated with immune-mediated inflammatory disorders (IMIDs; multiple sclerosis [MS], inflammatory bowel disease [IBD], and rheumatoid arthritis [RA]). We further aimed to determine the relationship between maltreatment and psychiatric comorbidity in IMIDs and whether these relationships differed across IMID.

METHODS

Six hundred eighty-one participants (MS, 232; IBD, 216; RA, 130; healthy controls, 103) completed a structured psychiatric interview to identify psychiatric disorders, and the Childhood Trauma Questionnaire to evaluate five types of maltreatment: emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect. We evaluated associations between maltreatment, IMID, and psychiatric comorbidity using multivariable logistic regression models.

RESULTS

The prevalence of having ≥1 maltreatment was similar across IMID but higher than in controls (MS, 63.8%; IBD, 61.6%; RA, 62.3%; healthy controls, 45.6%). Emotional abuse was associated with having an IMID (adjusted odds ratio [aOR] = 2.37; 1.15-4.89). In the sex-specific analysis, this association was only present in women. History of childhood maltreatment was associated with a lifetime diagnosis of a psychiatric disorder in the IMID cohort (OR = 2.24; 1.58-3.16), but this association did not differ across diseases. In those with IMID, total types of maltreatments (aOR = 1.36; 1.17-1.59) and emotional abuse (aOR = 2.64; 1.66-4.21) were associated with psychiatric comorbidity.

CONCLUSIONS

Childhood maltreatment is more common in IMID than in a healthy population and is associated with psychiatric comorbidity. Given the high burden of psychiatric disorders in the IMID population, clinicians should be aware of the contribution of maltreatment and the potential need for trauma-informed care strategies.

Association of Child Abuse and Systemic Lupus Erythematosus in Black Women During Adulthood

OBJECTIVE

Exposure to psychosocial stressors may contribute to the onset of systemic lupus erythematosus (SLE) through dysregulation of the adaptive stress response. The present study was undertaken to assess the relationship of childhood physical and sexual abuse to risk of SLE among Black women.

METHODS

Using data from the Black Women's Health Study, we followed 36,152 women from 1995 through 2015 with biennial questionnaires. Women reported on exposure to abuse during childhood (up to age 11) in 2005. Self-reported cases of incident SLE were confirmed as meeting the American College of Rheumatology SLE classification criteria by medical record review. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for SLE among women exposed to physical or sexual abuse during childhood, controlling for potential confounders.

RESULTS

We confirmed 101 cases of incident SLE and identified patients who had completed questions on child abuse during 670,822 person-years of follow-up. Both physical and sexual abuse during childhood were associated with statistically significant increases in SLE incidence. The HR for SLE associated with ≥2 episodes of severe sexual abuse compared to no abuse was 2.51 (95% CI 1.29-4.85) after adjustment for alcohol consumption, smoking, body mass index, oral contraceptive use, age at menarche, and parental education. The multivariable-adjusted HR for SLE with ≥5 episodes of severe physical abuse was 2.37 (95% CI 1.13-4.99).

CONCLUSION

Our results suggest that sexual and physical abuse during childhood increase SLE risk during adulthood among Black women. Research is necessary both to confirm this finding and to understand potential mediating mechanisms.

Pathways linking census tract typologies with subjective neighborhood disorder and depressive symptoms in the Black Women's Experiences Living with Lupus (BeWELL) Study

Depression is a common comorbidity among Black women with systemic lupus erythematosus (SLE), an understudied autoimmune disease characterized by major racial and gender inequities. Research is needed that examines how area-level factors influence risk of depression in this population. Latent profile analysis revealed four neighborhood typologies among metropolitan Atlanta, Georgia census tracts that participants (n=438) in the Black Women's Experiences Living with Lupus (BeWELL) Study were living in: Integrated/High-SES, Moderately Segregated/Mid-SES, Highly Segregated/Mid-SES, and Highly Segregated/Low-SES. Structural equation models indicated that highly segregated census tracts were associated with the greatest levels of depression via increased subjective assessments of neighborhood disorder. Policies that invest in segregated areas and address physical and social aspects of the environment that contribute to neighborhood disorder may promote mental health among Black women with SLE.

Posttraumatic Stress Disorder and the Associated Risk of Autoimmune Skin Diseases: A Nationwide Population-Based Cohort Study

OBJECTIVE

Posttraumatic stress disorder (PTSD) is known as a risk factor for various immune-related disorders; however, the association between PTSD and related autoimmune skin diseases (ASDs) remains unclear. This study aimed to investigate the association of PTSD with the risk of related ASDs.

METHODS

Participants were recruited from the National Health Insurance Research Database in Taiwan. We included 9801 patients with PTSD and 39,204 matched controls to assess the risk of developing ASDs. Cox regression model was used for analyses.

RESULTS

After adjusting for confounders, we found an increased risk of ASDs among the patients with PTSD (adjusted hazard ratio [aHR] = 3.00, 95% confidence interval [CI] = 2.21-4.07) compared with that among matched controls. Statistically significant associations were found between PTSD and five individual ASDs, including psoriasis (aHR = 3.81, 95% CI = 1.90-7.67), lichen planus (aHR = 31.63, 95% CI = 4.00-249.91), alopecia areata (aHR = 4.77, 95% CI = 2.47-9.20), autoimmune bullous diseases (aHR = 9.55, 95% CI = 1.98-45.99), and vitiligo (aHR = 16.06, 95% CI = 4.48-57.54).

CONCLUSIONS

Patients with PTSD had an increased risk of developing ASDs compared with the matched controls. Further studies are needed for better understanding of the underlying mechanisms.

Predictors of Adverse outcomes in patients with systemic lupus erythematosus transitioning to adult care

BACKGROUND

The transition from pediatric to adult care is a vulnerable period for individuals with chronic diseases. We sought to identify risk factors associated with poor outcomes in patients with childhood-onset systemic lupus erythematosus (cSLE) who have transitioned to adult care.

METHODS

A retrospective analysis of cSLE patients was performed. Outcomes of interest were development of end-stage renal disease (ESRD) or death and time to first hospitalization following final pediatric rheumatology visit. Multivariable logistic and Cox regression models were used.

RESULTS

Of 190 patients with cSLE, 21 (11%) developed ESRD and 9 (5%) died following the final pediatric rheumatology visit. In logistic regression, public insurance, history of Child Protective Services involvement, and an unscheduled hospitalization during the final year in pediatric care were predictive of ESRD or death (odds ratio (95% confidence intervals (CI)) 6.7 (1.5-30.7), 6.6 (2.3-19.1), and 3.2 (1.3-8.3), respectively). Among 114 patients with healthcare utilization data, 53% had a hospitalization in adult care. In Cox regression analysis, a pediatric outpatient opioid prescription was associated with shorter time to adult hospitalization and White or Asian race was associated with longer time to adult hospitalization (hazard ratio (CI) 3.5 (1.7-7.0) and 0.1 (0.03-0.4), respectively).

CONCLUSIONS

Risks factors associated with poor outcomes in adult care amongst patients with cSLE include public insurance, history of Child Protective Services involvement, unscheduled care utilization in pediatric care, pediatric outpatient opioid prescription, Black race and Hispanic ethnicity. Efforts to improve long-term outcomes among patients with cSLE should focus on these populations.

A prospective study of reproductive factors in relation to risk of systemic lupus erythematosus among black women

OBJECTIVE

Systemic lupus erythematosus (SLE) occurs most commonly among reproductive age women, compatible with a potential role of reproductive factors, although past studies including women of mainly European ancestry have yielded conflicting results. We assessed relationships of reproductive factors to SLE risk among black women.

METHODS

We followed 58,243 participants in the Black Women's Health Study (BWHS) from 1995 - 2015 using biennial health questionnaires, on which participants reported reproductive and other factors. Self-reported incident SLE cases were confirmed as meeting 1997 American College of Rheumatology SLE classification criteria by medical record review. Cox proportional hazards regression models were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for SLE for several reproductive factors, controlling for potential confounders.

RESULTS

During 954,476 person-years of follow-up, 125 incident cases of SLE were confirmed. Later age at menarche and longer duration of breast feeding were associated with increased risk of SLE. The multivariable HRs were 2.31 (95% CI, 1.30-4.11) for age at menarche ≥15 relative to age 12, and 1.73 (95% CI, 1.01-2.94) for breast feeding ≥6 months relative to none. There were no clear associations with parity, age at first birth, menopausal status, hysterectomy, age at menopause, or history of endometriosis.

CONCLUSION

Our results suggest that later menarchal age and breastfeeding of infants for ≥6 months vs. none may be associated with increased SLE risk among black women, while other reproductive factors did not appear related. The biological mechanisms underlying these potential associations should be pursued.

Socioeconomic Status, Health Care, and Outcomes in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) disproportionately affects those with low socioeconomic status. Evidence from the past 2 decades has revealed clearer distinctions on the mechanisms of poverty that affect long-term outcomes in SLE. Poverty exacerbates direct, indirect, and humanistic costs and is associated with worse SLE disease damage, greater mortality, and poorer quality of life. Ongoing commitments from medicine and society are required to reduce disparities, improve access to care, and bolster resilience in persons with SLE who live in poverty.

Hidradenitis suppurativa is associated with childhood and lifetime traumatic events: a case-control study

BACKGROUND

Negative life events in childhood can increase the susceptibility to autoimmune and inflammatory diseases. Hidradenitis suppurativa (HS) is a systemic inflammatory disease affecting the apocrine sweat glands, characterized by abscesses, fistulas and inflammatory nodules. It is unknown whether adult HS is associated with traumatic events.

OBJECTIVE

To investigate the association between childhood and total lifetime traumatic events and the presence of HS.

METHODS

We conducted a matched (1 : 3) case-control study with 71 HS patients and 213 controls. Patients were matched on age, gender and level of education. Questionnaires on general and demographic information, as well as the Traumatic Experience Checklist and the Hospital Anxiety and Depression Scale, were completed.

RESULTS

The number of traumatic events (OR: 1.20 per trauma, P value < 0.05), and childhood traumatic events (yes vs. no, OR 3.59, P value < 0.05) and the number of childhood traumatic events (OR 1.35 per trauma, P value < 0.05) were correlated with an increased risk of developing HS. Detailed analysis showed that childhood emotional traumatic events (OR 5.03, P value < 0.05) were significantly associated with the development of HS.

CONCLUSION

Number of lifetime traumatic events and childhood traumatic events are associated with HS. This association is strongest for emotional childhood traumas. The increased prevalence of childhood traumas in HS patients can be one of the underlying mechanisms leading to systemic inflammation in these patients.
