[PMID: 38458465 DOI: 10.1016/j.scitotenv.2024.171492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 03/03/2024] [Accepted: 03/03/2024] [Indexed: 03/10/2024]
Abstract
Polycyclic aromatic hydrocarbons (PAHs) are hydrocarbons characterized by the presence of multiple benzene rings. They are ubiquitously found in the natural environment, especially in environmental pollutants, including atmospheric particulate matter, cigarette smoke, barbecue smoke, among others. PAHs can influence human health through several mechanisms, including the aryl hydrocarbon receptor (AhR) pathway, oxidative stress pathway, and epigenetic pathway. In recent years, the impact of PAHs on inflammatory skin diseases has garnered significant attention, yet many of their underlying mechanisms remain poorly understood. We conducted a comprehensive review of articles focusing on the link between PAHs and several inflammatory skin diseases, including psoriasis, atopic dermatitis, lupus erythematosus, and acne. This review summarizes the effects and mechanisms of PAHs in these diseases and discusses the prospects and potential therapeutic implications of PAHs for inflammatory skin diseases.

Abstract
Introduction Lupus is a diverse autoimmune disease with autoantibody formation. Lupus nephritis carries a grave prognosis. Complement involvement, namely, C1q deficiency, is linked to activity and renal involvement and could help in their assessment. LN therapies include plasma exchange, immune adsorption, and probably hemodiafiltration with online endogenous reinfusion (HFR), together with traditional immunosuppressive therapies. Aim The aim of this study was to evaluate the role of HFR in improving signs and symptoms of systemic lupus erythematosus (SLE) activity and laboratory parameters in cases not responding to traditional immunosuppressive therapy. Settings and design A controlled clinical study was conducted on 60 patients with lupus from Group A that was subdivided into two groups: cases 1 (47 patients), those who received traditional medical treatment, and cases 2 (13 patients), those who underwent HFR in addition to medical treatment. Group B consisted of two subgroups: control 1, composed of 20 healthy age- and sex-matched volunteers, and control 2, consisting of 10 cases with different glomerular diseases other than lupus. Methods and materials Serum C1q was determined before and after the HFR as well as induction by medical treatment. Disease activity was assessed using SLEDAI-2K with a responder index of 50; quality of life was assessed using SLEQOL v2, and HFR was performed for the non-responder group. Results C1q was lower in cases. It can efficiently differentiate between SLE patients and healthy controls with a sensitivity of 81.67% and a specificity of 90%. It can also efficiently differentiate between SLE patients and the control 2 group (non-lupus patients with renal glomerular disease) with a sensitivity of 83.33% and a specificity of 100%. C1q was more consumed in proliferative lupus, and correlated with anti-ds DNA, C3, and C4. Conclusions C1q efficiently discriminates lupus patients and correlates with proliferative forms. HFR might ameliorate lupus activity and restore C1q.

Abstract
Though more common earlier in life, increasing attention is being focused on the development of cutaneous lupus erythematosus (CLE) in patients with advancing age. Studies show that CLE is more common in older populations than previously thought, and all CLE subtypes are possible in this group. Just like patients in the third or fourth decade of life, CLE may appear alongside or independent of systemic lupus erythematosus. Older populations manifesting CLE for the first time seem to have a lower risk of progression to systemic disease than younger peers, and are more commonly White. CLE must be carefully distinguished from other skin conditions that have a predilection for presentation in older populations, including rosacea, lichen planus, and other autoimmune conditions such as dermatomyositis or pemphigus/pemphigoid. It is thought that most CLE in older populations is drug-induced, with drug-induced subacute cutaneous lupus erythematosus being the most common subtype. Management of CLE in older patients focuses on eliminating unnecessary medications known to induce CLE, and otherwise treatment proceeds similarly to that in younger patients, with a few special considerations.

Abstract
Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease characterized by diverse manifestations, notably in dermatological and neurological domains. This review aims to synthesize the current understanding of these manifestations and their impact on long-term prognosis. Adhering to PRISMA guidelines, we conducted a comprehensive search across multiple databases, focusing on studies exploring SLE's dermatological and neurological aspects. Selected studies were analyzed to understand their epidemiology, pathophysiology, clinical presentation, and impact on prognosis. Six pivotal studies were reviewed, highlighting the severity of neuropsychiatric SLE, the progression of skin diseases, and their systemic implications. Notably, studies underscored the role of high disease activity and specific antibodies in the development of neuropsychiatric symptoms and the progression of cutaneous manifestations. The review emphasizes the need for an interdisciplinary approach to managing SLE, considering the interplay between its dermatological and neurological manifestations. It suggests that tailored treatment strategies, early detection, and comprehensive care are crucial for improving patient outcomes. This synthesis provides a foundation for future research to develop integrated care protocols and advance patient care in SLE.

The differential panorama of clinical features of lupus erythematosus patients with different onset ages: a cross-sectional multicenter study from China. Clin Rheumatol 2023; 42:2353-2367. [PMID: 37311918 DOI: 10.1007/s10067-023-06661-1] [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: 11/06/2022] [Revised: 04/25/2023] [Accepted: 06/01/2023] [Indexed: 06/15/2023]
Abstract
OBJECTIVES This study aims to compare the differences among patients of different onset ages in various subtypes of lupus erythematosus (LE) and to draw a panorama of the clinical characteristics of patients with different onset ages. METHOD Subjects were recruited from the Lupus Erythematosus Multicenter Case-control Study in Chinese populations (LEMCSC), grouped by the age of onset (childhood-onset: onset < 18 years, adult-onset: onset 18-50 years, late-onset: onset > 50 years). The data collected included demographic characteristics, LE-related systemic involvement, LE-related mucocutaneous manifestations, and laboratory results. All included patients were assigned into three groups: systemic LE (SLE) group (with systemic involvement, with or without mucocutaneous lesions), cutaneous LE (CLE) group (patients who were accompanied by any type of LE-specific cutaneous manifestations), and isolated cutaneous LE (iCLE) group (patients who were in CLE group without systemic involvements). Data were analyzed using R version 4.0.3. RESULTS A total of 2097 patients were involved, including 1865 with SLE and 232 with iCLE. We also identified 1648 patients with CLE among them, as there was some overlap between the SLE population and CLE population (patients with SLE and LE-specific cutaneous manifestations). Later-onset lupus patients seemed to be less female predominance (p < 0.001) and have less systemic involvement (except arthritis), lower positive rates of autoimmune antibodies, less ACLE, and more DLE. Moreover, childhood-onset SLE patients presented a higher risk of LE family history (p = 0.002, vs adult-onset SLE). In contrast to other LE-nonspecific manifestations, the self-reported photosensitivity history decreased with the age of onset in SLE patients (51.8%, 43.4%, and 39.1%, respectively) but increased in iCLE patients (42.4%, 64.9%, and 89.2%, respectively). There was also a gradual increase in self-reported photosensitivity from SLE, CLE, to iCLE in both adult-onset and late-onset lupus patients. CONCLUSIONS A negative correlation was suggested between the age of onset and the likelihood of systemic involvement, except for arthritis. As the age of onset increases, patients have a greater propensity to exhibit DLE compared to ACLE. Moreover, the presence of rapid response photodermatitis (i.e., self-reported photosensitivity) was associated with a lower rate of systemic involvement. TRIAL REGISTRATION This study was registered with the Chinese Clinical Trial Registry (registration number: ChiCTR2100048939) on July 19, 2021, retrospectively registered. Key Points • We confirmed some phenomena that have been found in patients with SLE, such as the highest proportion of females of reproductive age, the higher risk of LE family history in childhood-onset SLE patients, and the less self-reported photosensitivity in the late-onset SLE group. We also compared the similarities and differences of these phenomena in patients with CLE or iCLE for the first time. • In patients with SLE, the proportion of females peaked in adult-onset patients, but this phenomenon disappeared in iCLE patients: the female-male ratio tends to decrease from childhood-onset iCLE, adult-onset iCLE, to late-onset iCLE. • Patients with early-onset lupus are more likely to have acute cutaneous lupus erythematosus (ACLE), and patients with late-onset lupus are more likely to have discoid lupus erythematosus (DLE). • In contrast to other LE-nonspecific manifestations, the incidence of rapid response photodermatitis (i.e., self-reported photosensitivity) decreased with the age of onset in SLE patients but increased with the age of onset in iCLE patients.

Abstract
BACKGROUND Sex and gender have increasingly been recognized as significant risk factors for many diseases, including dermatological conditions. Historically, sex and gender have often been grouped together as a single risk factor in the scientific literature. However, both may have a distinct impact on disease incidence, prevalence, clinical presentation, severity, therapeutic response, and associated psychological distress. OBJECTIVES AND PROJECT DESCRIPTION The mechanisms that underlie differences in skin diseases between males, females, men, and women remain largely unknown. The specific objectives of this review paper are:To highlight the biological differences between males and females (sex), as well as the sociocultural differences between men and women (gender) and how they impact the integumentary system.To perform a literature review to identify important sex- and gender-related epidemiological and clinical differences for various skin conditions belonging to a range of disease categories and to discuss possible biological and sociocultural factors that could explain the observed differences.To discuss dermatological skin conditions and gender-affirming treatments within the transgender community, a population of individuals who have a gender identity which is different than the gender identity they were assigned at birth. FUTURE IMPACT With the rising number of individuals that identify as non-binary or transgender within our increasingly diverse communities, it is imperative to recognize gender identity, gender, and sex as distinct entities. By doing so, clinicians will be able to better risk-stratify their patients and select treatments that are most aligned with their values. To our knowledge, very few studies have separated sex and gender as two distinct risk factors within the dermatology literature. Our article also has the potential to help guide future prevention strategies that are patient-tailored rather than using a universal approach.

Abstract
Cutaneous lupus erythematosus (CLE) is classified into three groups - acute, subacute, and chronic - based on clinical and histopathological characteristics. The risk of systemic manifestations varies among these groups. There are few studies on CLE epidemiology. For this reason, this paper aims to describe CLE prevalence and demographics in Colombia between 2015 and 2019. This descriptive, cross-sectional study used the international classification of diseases, tenth revision, for CLE subtypes, utilizing official data from the Colombian Ministry of Health. In people older than 19 years, 26,356 CLE cases were registered, yielding a prevalence of 76 cases per 100,000 population. CLE was more frequent in females, at a 5:1 ratio compared to males. The most common clinical presentation was discoid lupus erythematosus, in 45% of cases. The majority of cases occurred in people between 55 and 59 years old. This is the first study that describes CLE demographics in adults in Colombia. Findings regarding clinical subtypes and female predominance are consistent with those in the medical literature.

Abstract
OBJECTIVE Lupus erythematosus (LE) is a complicated disease with highly heterogeneous clinical manifestations. Previous studies have rarely included all subgroups of patients with lupus and have overlooked the importance of the cutaneous manifestations thereof. We aimed to compare the demographic and clinical differences among patients with different subtypes of lupus. METHODS This is the first real-world study with a relatively large sample size that simultaneously includes patients with isolated cutaneous lupus erythematosus (iCLE) and SLE. All samples were obtained from the Lupus Erythematosus Multicenter Case-control Study in Chinese populations (LEMCSC) (registration number: ChiCTR2100048939). Comparative analyses between different LE subgroups were performed. RESULTS A total of 2097 patients with lupus were included, with 1865 patients with SLE, 1648 with cutaneous lupus erythematosus (CLE), and 232 with iCLE. Among the patients with CLE, 1330 had acute cutaneous lupus erythematosus (ACLE); 160 had subacute cutaneous lupus erythematosus (SCLE); and 546 had chronic cutaneous lupus erythematosus (CCLE). The study included a relatively large number of patients with CCLE subtypes, including 311 with discoid lupus erythematosus (DLE), 262 with chilblain lupus erythematosus (CHLE) and 45 with lupus erythematosus profundus (LEP). Demographic characteristics, systemic involvement, mucocutaneous manifestations and autoantibodies were significantly different among the groups. CONCLUSIONS CLE and iCLE are two distinct disease states, and the selection of broad or narrow CLE definitions should be emphasised in scientific reports. LE-non-specific cutaneous lesions imply more severity, while self-reported photosensitivity and LE-specific cutaneous manifestations imply milder severity. Generalised ACLE appears to be a more severe state than localised ACLE, and CHLE appears to be more severe than DLE. Anti-Sjögren's syndrome-related antigen B (SSB) antibodies have higher specific directivity than anti-Sjögren's syndrome-related antigen A (SSA) antibodies for SCLE lesions. Anti-double-stranded DNA antibodies have a higher co-occurrence with ACLE and a lower co-occurrence with SCLE and CCLE. Compared with DLE, CHLE has significantly higher positive rates of anti-SSA/Ro60 (71%) and anti-SSA/Ro52 (42.4%) antibodies, whereas LEP is associated with a higher positive rate of antinucleosome antibodies (31.1%).

Abstract
Cutaneous lupus erythematosus (CLE) is a common disease that may appear as a separate entity from systemic lupus erythematosus (SLE), precede SLE development, or occur as a manifestation of this systemic disease. It has a complex pathophysiology that involves genetic, environmental, and immune-mediated factors creating a self-amplification pro-inflammatory cycle. CLE is characterized by prominent type I interferons (IFNs) inflammation which are considered as the first precursors of the inflammatory cascade generated within the pathophysiology of CLE. TNF-α enhances the production of antibodies through the activation of B cells, and favors the expression of surface nuclear antigens on keratinocytes. UV light exposure favors keratinocyte apoptosis or necroptosis, which results in the release of multiple proinflammatory cytokines, including IL-6, IL-1α, IL-1β, TNF-α, IFNs, and CXCL10. Serum levels of IL-17 are elevated in patients with ACLE, SCLE, and DLE. Evidence suggests IL-22 plays a role primarily in tissue repair rather than in inflammation. High expression of BAFF and its receptors have been found in lesioned keratinocytes of patients with CLE, and patients with CLE have lower serum levels of the regulatory cytokines TGF-β and IL-10. The chemokines CXCL9 and CXCL10 (CXCR3 ligands) have an increased expression among these patients, and their expression is correlated with IFNs levels. CXCR3 ligands recruit cytotoxic type I cells through this receptor, further supporting the death of keratinocytes via necroptosis with the subsequent release of eNAs perpetuating the inflammatory cycle. Interface dermatitis is characterized by the presence of CXCR3-positive lymphocytes. This review describes the leading cytokines and chemokines present in the circulation and skin that play a fundamental role in the pathogenesis of CLE.

Abstract
OBJECTIVE To examine the effect of psychiatric diagnoses on healthcare use in youth with systemic lupus erythematosus (SLE) during their first year of SLE care. METHODS We conducted a retrospective cohort study using claims from 2000 to 2013 from Clinformatics Data Mart (OptumInsight). Youth aged 10 years to 24 years with an incident diagnosis of SLE (≥ 3 International Classification of Diseases, 9th revision, codes for SLE 710.0, > 30 days apart) were categorized as having: (1) a preceding psychiatric diagnosis in the year before SLE diagnosis, (2) an incident psychiatric diagnosis in the year after SLE diagnosis, or (3) no psychiatric diagnosis. We compared ambulatory, emergency, and inpatient visits in the year after SLE diagnosis, stratified by nonpsychiatric and psychiatric visits. We examined the effect of childhood-onset vs adult-onset SLE by testing for an interaction between age and psychiatric exposure on outcome. RESULTS We identified 650 youth with an incident diagnosis of SLE, of which 122 (19%) had a preceding psychiatric diagnosis and 105 (16%) had an incident psychiatric diagnosis. Compared with those without a psychiatric diagnosis, youth with SLE and a preceding or incident psychiatric diagnosis had more healthcare use across both ambulatory and emergency settings for both nonpsychiatric and psychiatric-related care. These associations were minimally affected by age at time of SLE diagnosis. CONCLUSION Psychiatric comorbidity is common among youth with newly diagnosed SLE and is associated with greater healthcare use. Interventions to address preceding and incident psychiatric comorbidity may decrease healthcare burden for youth with SLE.

Abstract
Cutaneous lupus erythematosus (CLE) is an autoimmune disease, which can be limited to the skin or associated with systemic lupus erythematosus (SLE). Gene expression analysis has revealed that both the innate and adaptive immune pathways are activated in CLE. Ultraviolet (UV) light, the predominant environmental factor associated with CLE, induces apoptosis in keratinocytes, and the endogenous nucleic acids released from the apoptotic cells are recognized via pattern recognition receptors, including Toll-like receptors. This leads to the production of type I interferon, a major contributor to the pathogenesis of CLE, by plasmacytoid dendritic cells. UV irradiation can also induce the externalization of autoantigens, such as SS-A/Ro, exposing them to circulating autoantibodies. T-helper 1 cells have been reported to play important roles in the adaptive immune response to CLE. Other environmental factors associated with CLE include drugs and cigarette smoke. Genetic factors also confer a predisposition to the development of CLE, and many susceptibility genes have been identified. Monogenetic forms of CLE also exist. This article aims to review current knowledge about the pathogenesis of CLE. A better understanding of the environmental, genetic, and immunoregulatory factors that drive CLE may provide important insights for the treatment of CLE.

Abstract
Central nervous system (CNS) involvement in childhood-onset systemic lupus erythematosus (cSLE) occurs in more than 50% of patients. Structural magnetic resonance imaging (MRI) has identified global cerebral atrophy, as well as the involvement of the corpus callosum and hippocampus, which is associated with cognitive impairment. In this cross-sectional study we included 71 cSLE (mean age 24.7 years (SD 4.6) patients and a disease duration of 11.8 years (SD 4.8) and two control groups: (1) 49 adult-onset SLE (aSLE) patients (mean age of 33.2 (SD 3.7) with a similar disease duration and (2) 58 healthy control patients (mean age of 29.9 years (DP 4.1)) of a similar age. All of the individuals were evaluated on the day of the MRI scan (Phillips 3T scanner). We reviewed medical charts to obtain the clinical and immunological features and treatment history of the SLE patients. Segmentation of the corpus callosum was performed through an automated segmentation method. Patients with cSLE had a similar mid-sagittal area of the corpus callosum in comparison to the aSLE patients. When compared to the control groups, cSLE and aSLE had a significant reduction in the mid-sagittal area in the posterior region of the corpus callosum. We observed significantly lower FA values and significantly higher MD, RD, and AD values in the total area of the corpus callosum and in the parcels B, C, D, and E in cSLE patients when compared to the aSLE patients. Low complement, the presence of anticardiolipin antibodies, and cognitive impairment were associated with microstructural changes. In conclusion, we observed greater microstructural changes in the corpus callosum in adults with cSLE when compared to those with aSLE. Longitudinal studies are necessary to follow these changes, however they may explain the worse cognitive function and disability observed in adults with cSLE when compared to aSLE.

Abstract
The majority of patients with systemic lupus erythematosus (SLE) have cutaneous manifestations at some point in their disease course. The skin findings in SLE are classified as SLE-specific or SLE-nonspecific based on histopathologic findings. SLE-specific skin diseases include chronic cutaneous lupus erythematosus (CLE), subacute CLE, and acute CLE. There are subsets of skin lesions within each group and the likelihood of associated SLE varies among them. SLE-nonspecific lesions are more common in patients with SLE and tend to coincide with active systemic disease. SLE-nonspecific lesions may be seen as a feature of another disease process, including other connective tissue diseases. It is important for the rheumatologist to be familiar with the spectrum of cutaneous diseases in SLE to help prognosticate the likelihood of systemic disease and to ensure patients receive timely dermatologic care with the goal of controlling disease activity to prevent damage.

Abstract
OBJECTIVE To characterize the epidemiological trends and mortality of cutaneous lupus erythematosus (CLE) between 1976 and 2018 in Olmsted County, Minnesota. PATIENTS AND METHODS In this retrospective population-based cohort study, all incident and prevalent CLE cases among adult residents in Olmsted County, Minnesota, between January 1, 1976, and December 31, 2018, were identified and categorized by subtype through medical record review using the resources of the Rochester Epidemiology Project. RESULTS The overall incidence rate of CLE between 1976 and 2018 was 3.9 (95% CI, 3.4 to 4.5) per 100,000. The incidence of CLE was relatively stable, with no major trend across sexes or age groups. The age- and sex-adjusted prevalence of CLE was 108.9 per 100,000 on January 1, 2015. Mortality in CLE patients was similar to that of the general population, with a standardized mortality ratio of 1.23 (95% CI, 0.88 to 1.66) with no observed trends in mortality over time. CONCLUSION In the past 4 decades, the incidence of CLE remained stable. Patients with CLE have mortality comparable to that of the general population.

Abstract
Background Bullous systemic lupus erythematosus (BSLE) is a rare subtype of systemic lupus erythematosus (SLE) that is clinically characterized by subepidermal tense vesicles or bullae. We aimed to investigate the clinical and laboratory features of patients with BSLE.
Methods We retrospectively reviewed all patients who fulfilled the diagnostic criteria for BSLE in our institution from 2015 to 2021. Cutaneous lesions, systemic manifestations, treatment options, and outcomes were evaluated. For each case of BSLE, four controls were randomly selected from patients with single SLE. Major clinical and laboratory characteristics were compared between the two groups. Results Among 4221 patients with SLE, 12 developed BSLE. Vesiculobullous lesions were the first sign in five of the BSLE patients (5/12, 41.7%) and appeared after SLE diagnosis in the remaining seven patients (7/12, 58.3%), with a median duration from SLE onset of 36 months (4–115 months). The most common BSLE-affected sites were the head and neck (10/12, 83.3%), extremities (9/12, 75.0%), trunk (7/12, 58.3%), and mucosae (6/12, 50.0%). All patients with BSLE had extra-cutaneous involvement. The SLE disease activity index score exceeded 5 in 10/12 (83.3%) patients, which indicated high disease activity. Patients in the BSLE group had significantly higher incidences of proteinuria (83.3% vs. 47.9%, P = 0.027), hematuria (75% vs. 31.3%, P = 0.006), hemolytic anemia (33.3% vs. 0%, P = 0.000), and leukopenia (66.7% vs. 25.0%, P = 0.006) than those in the control group. The use of systemic corticosteroids, immunosuppressants, dapsone, and skin care was effective in controlling disease. Conclusions Vesiculobullous lesions may be the first manifestation and indicate a high disease activity in patients with BSLE. Early diagnosis using clinical, histopathological, and immunological evaluations can lead to appropriate treatment of this progressive disease and improve prognosis.

Abstract
Cutaneous lupus erythematosus (CLE) is an inflammatory and autoimmune skin condition that affects patients with systemic lupus erythematosus (SLE) and exists as an isolated entity without associated SLE. Flares of CLE, often triggered by exposure to ultraviolet (UV) light result in lost productivity and poor quality of life for patients and can be associated with trigger of systemic inflammation. In the past 10 years, the knowledge of CLE etiopathogenesis has grown, leading to promising targets for better therapies. Development of lesions likely begins in a pro-inflammatory epidermis, conditioned by excess type I interferon (IFN) production to undergo increased cell death and inflammatory cytokine production after UV light exposure. The reasons for this inflammatory predisposition are not well-understood, but may be an early event, as ANA + patients without criteria for autoimmune disease exhibit similar (although less robust) findings. Non-lesional skin of SLE patients also exhibits increased innate immune cell infiltration, conditioned by excess IFNs to release pro-inflammatory cytokines, and potentially increase activation of the adaptive immune system. Plasmacytoid dendritic cells are also found in non-lesional skin and may contribute to type I IFN production, although this finding is now being questioned by new data. Once the inflammatory cycle begins, lesional infiltration by numerous other cell populations ensues, including IFN-educated T cells. The heterogeneity amongst lesional CLE subtypes isn't fully understood, but B cells appear to discriminate discoid lupus erythematosus from other subtypes. Continued discovery will provide novel targets for additional therapeutic pursuits. This review will comprehensively discuss the contributions of tissue-specific and immune cell populations to the initiation and propagation of disease.

Abstract
Cutaneous lupus erythematosus (CLE) is an autoimmune disorder like systemic lupus erythematosus (SLE). Both SLE and CLE characterize autoantibody secretion and immune cell recruitment. In particular, CLE can be divided into three more frequent types, varying in the severity of the skin lesions they present. The role of type I IFN was shown to be one of the leading causes of the development of this pathology in the skin. Different treatments have been developed and tested against these different variants of CLE to decrease the increasing levels of CLE in humans. In this article, a literature revision discussing the similarities between SLE and CLE is carried out. In addition, new advances in understanding the development of CLE and the leading treatments being evaluated in animal models and clinical trials are reviewed.

Abstract
BACKGROUND Cutaneous lupus erythematosus (CLE) can present later in life, but frequency and risk factors of late-onset CLE patients are not well characterized. The study determined frequency of late-onset CLE and compared the demographic and disease characteristics between early-onset and late-onset CLE in a cohort of patients with CLE. OBJECTIVES To determine the frequency and compare clinical features of early-onset and late-onset CLE. METHODS This was a cross-sectional study of CLE patients seen in outpatient dermatology clinics at University of Texas Southwestern Medical Center (UTSW) and Parkland Health and Hospital System, Dallas, TX, from April 2009 to May 2019. The primary outcome was the age of CLE onset, stratified by early-onset (<50 years) and late-onset CLE (≥50 years). Predictor variables significantly associated with CLE onset groups were identified by univariate and multivariable logistic regression analyses. RESULTS Of the 291 CLE patients studied, 79% were early-onset, and 21% were late-onset. Multivariable logistic regression analyses identified that Caucasian race (odds ratio (OR): 2.23, 95% Confidence Interval (CI): 1.19-4.19, p = 0.013), having a CLE subtype other than chronic (OR: 2.18, 95% CI: 1.02-4.65, p = 0.044), and drug-induced cases (OR: 4.65, 95% CI: 1.18-18.24, p = 0.028) were significantly associated with late-onset CLE. Early-onset CLE patients were more likely to have oral ulcers (OR: 3.58, 95% CI: 1.46-8.78, p = 0.005) and renal disorders (OR: 4.02, 95% CI: 1.10-14.71, p = 0.036). LIMITATIONS This was a single center study. Age of onset was self-reported and late-onset CLE cohort has a small sample size. CONCLUSIONS Our diverse cohort of CLE patients had about one out of five patients with CLE experiencing disease onset after 50 years old. These patients have distinct demographic and clinical presentations compared to early-onset CLE patients. Providers should remain mindful of CLE in older patients with photosensitive rashes and mild systemic symptoms.

Abstract
Cutaneous lupus erythematosus (CLE) is a group of heterogeneous autoimmune disorders primarily affecting the skin. Patients with these conditions are mostly young women when they become sick and often suffer from recurrent skin symptoms or longstanding changes in their physical appearance. CLE disorders lead to different levels of morbidity and can impact profoundly patients' quality of life, particularly in the psychological and social health domains. This review provides a summary of recent research investigating the psychosocial burden of living with CLE and the intersect amongst the disease characteristics, patient factors, and social determinants of health. Furthermore, this review provides insight into patient care and research needs that remain unmet to improve the quality of life of patients living with CLE.

Abstract
Cutaneous lupus erythematosus (CLE) is a chronic autoimmune skin disease with potential for systemic involvement, disfigurement, and significant disease burden. The relationships of demographics and socioeconomic status with patients with CLE are emerging topics with important clinical implications. The primary objective of our study is to perform a literature review of studies that have investigated demographic and socioeconomic factors amongst patients with CLE and determine whether these factors influence diagnosis frequency, disease severity and outcomes or health related quality of life. We searched multiple databases to identify literature addressing CLE and concepts such as race, ethnicity, gender, income, education level and geographic location. Information regarding primary research objective was extracted from all full text articles, and a summary of findings was prepared. We found that race and ethnicity can influence CLE diagnosis frequency and disease outcomes. Chronic cutaneous lupus (CCLE) occurs more frequently in Black patients, often with higher overall disease damage. Differences between genders exist in CLE in terms of health-related quality of life, as female gender was a risk factor for worse quality of life in several studies. Lower income, low educational attainment, and lack of health insurance all contribute to poorer overall outcomes in CLE patients. This review will help inform physicians about populations at risk for potentially worse outcomes to guide treatment decisions for patients with CLE and provide important information to design interventions that address modifiable social determinants of health in this population.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) risk has been associated with pesticide use, but evidence on specific pesticides or other agricultural exposures is lacking. We investigated history of pesticide use and risk of SLE and a related disease, Sjögren's syndrome (SS), in the Agricultural Health Study. METHODS The study sample (N = 54,419, 52% male, enrolled in 1993-1997) included licensed pesticide applicators from North Carolina and Iowa and spouses who completed any of the follow-up questionnaires (1999-2003, 2005-2010, 2013-2015). Self-reported cases were confirmed by medical records or medication use (total: 107 incident SLE or SS, 79% female). We examined ever use of 31 pesticides and farm tasks and exposures reported at enrollment in association with SLE/SS, using Cox regression to estimate hazard ratios (HR) and 95% confidence intervals (CI), with age as the timescale and adjusting for gender, state, and correlated pesticides. RESULTS In older participants (>62 years), SLE/SS was associated with ever use of the herbicide metribuzin (HR 5.33; 95%CI 2.19, 12.96) and applying pesticides 20+ days per year (2.97; 1.20, 7.33). Inverse associations were seen for petroleum oil/distillates (0.39; 0.18, 0.87) and the insecticide carbaryl (0.56; 0.36, 0.87). SLE/SS was inversely associated with having a childhood farm residence (0.59; 0.39, 0.91), but was not associated with other farm tasks/exposures (except welding, HR 2.65; 95%CI 0.96, 7.35). CONCLUSIONS These findings suggest that some agricultural pesticides may be associated with higher or lower risk of SLE/SS. However, the overall risk associated with farming appears complex, involving other factors and childhood exposures.

Abstract
• Discoid lupus may be associated with SLE. In this study, most children with discoid lupus did not have systemic disease. Concurrent SLE was highest in female adolescents (>10 years of age) with generalized discoid lupus, who had clinically aggressive disease. • Discoid lupus in adolescence should prompt thorough evaluation for SLE.

Abstract
BACKGROUND Cutaneous lupus erythematosus (CLE) is a chronic, autoimmune skin disease with a wide spectrum of clinical presentations in different populations. OBJECTIVE To study the clinico-histological and immunological features of CLE in a multi-ethnic population and to identify the predictive factors of disease severity based on CLE disease area and severity index (CLASI) scores. METHODS This is a cross-sectional study of CLE conducted from March 2019 till February 2020. RESULTS A total of 111 patients were recruited with female to male ratio of 4.9:1. Acute CLE contributed 47.7%, followed by chronic CLE, 46.9% and subacute CLE, 5.4%. Eighty-four percent of patients had systemic lupus erythematosus. About 67.3% with chronic CLE developed systemic involvement. Anti-nuclear antibody (ANA) was detected in 90.0%. Skin biopsy(n=42) showed perivascular lymphocytic infiltration (95.2%), epidermal atrophy (47.6%) and hydropic degeneration of basal layer (47.6%). More than 40% had immunoglobulin deposition at dermo-epidermal junction, predominantly granular pattern. Mean CLASI-total was 6.44±7.70, CLASI-activity 2.75±4.10 and CLASI-damage 3.71±4.76. Body surface area (BSA) involved was found to be an independent predictive factor for CLASI-activity (OR:1.34, p=0.018). For CLASI-damage, BSA (OR:4.14, p<0.0001), discoid lupus erythematosus (DLE) subtype (OR:13.10, p=0.001), cutaneous vascular disease (OR:26.59, p=0.014), scalp involvement (OR:8.7, p=0.008) and hypocomplementemia (OR:5.71, p=0.046) were the positive predictive factors. Mean DLQI was 5.91 ± 5.34 and it correlated significantly with disease severity. CONCLUSIONS We observed a high percentage of patients with CLE with systemic manifestations and positive ANA. More aggressive treatment of those with positive predictive factors for severe disease combined with significant clinical activity may be warranted.

Abstract
Cutaneous Lupus Erythematosus (CLE) is an autoimmune skin disease that occurs in almost two-thirds of people with Systemic Lupus Erythematosus (SLE) and can exist as its own entity. Despite its negative impact on the quality of life of patients, lupus pathogenesis is not fully understood. In recent years, the role of gene expression analysis has become important in understanding cellular functions and disease causation within and across species. Interestingly, dogs also develop CLE, providing a spontaneous animal model of disease. Here, we present a targeted transcriptomic analysis of skin biopsies from a case series of four dogs with complex autoimmunity with suspected CLE. We identified 92 differentially expressed genes (DEGs), including type 1 interferon, B cell, and T cell-related genes, in the four cases compared to healthy skin margin controls. Additionally, we compared our results with existing CLE datasets from humans and mice and found that humans and canines share 49 DEGs, whereas humans and mice shared only 25 DEGs in our gene set. Immunohistochemistry of IFNG and CXCL10, two of the most highly upregulated inflammatory mediators, confirmed protein-level expression and revealed immune cells as the primary source of CXCL10 in dogs with SLE, whereas keratinocytes stained strongly for CXCL10 in dogs without SLE. We propose that gene expression analysis may aid the diagnosis of complex autoimmune skin diseases and that dogs may provide important insights into CLE and SLE pathogeneses, or more broadly, skin manifestations during systemic autoimmunity.

Abstract
To explore bias in lupus erythematosus (LE) randomized clinical trials (RCTs) and to help the development of benchmarks for future trials and management. We searched systematically three databases and three registries to summarize the interventional randomized clinical trials (RCTs) and identify factors associated with participant loss. Trials which examined pharmacological interventions with control group were included and a meta-analysis was carried out by using fixed and random effects models to calculate risk ratio of participant loss in the intervention and control groups. A total of 481 trials with 68,582 participants met our inclusion criteria, organ specific interventional studies along with trials that address quality of life attributes and geopolitical disparities are missing or lagging behind. 90 trials were involved in the meta-analyses, the withdrawal ratio between intervention and control groups was distinctly influenced by national income of the trial-conducted country. In high income countries, the withdrawal ratio was relatively constant, while for trials conducted in low and middle income countries, the results were altered by trial registration, year of start, number of centers, number of participants, and primary outcome identification. Moreover, the comparability of participants was also worrying, trial location and registration status altered basal participant adherence. Our study reveals the unexpectedly huge heterogeneity brought by national income and trial registration in lupus RCTs worldwide. To maintain the fundamental repeatability and referenceability of LE RCTs, rigorously designed single-country trials with diverse inclusion criteria are needed.

Bioinformatics analyses of gene expression profile identify key genes and functional pathways involved in cutaneous lupus erythematosus. Clin Rheumatol 2021; 41:437-452. [PMID: 34553293 DOI: 10.1007/s10067-021-05913-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 07/05/2021] [Accepted: 09/05/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Lupus erythematosus is an autoimmune disease that causes damage to multiple organs ranging from skin lesions to systemic manifestations. Cutaneous lupus erythematosus (CLE) is a common type of lupus erythematosus (LE), but its molecular mechanisms are currently unknown. The study aimed to explore changes in the gene expression profiles and identify key genes involved in CLE, hoping to uncover its molecular mechanism and identify new targets for CLE. METHOD We analyzed the microarray dataset (GSE109248) derived from the Gene Expression Omnibus (GEO) database, which was a transcriptome profiling of CLE cutaneous lesions. The differentially expressed genes (DEGs) were identified, and the functional annotation of DEGs was performed with Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Protein-protein interaction (PPI) network was also constructed to identify hub genes involved in CLE. RESULT A total of 755 up-regulated DEGs and 405 down-regulated DEGs were identified. GO enrichment analysis showed that defense response to virus, immune response, and type I interferon signaling pathway were the most significant enrichment items in DEGs. The KEGG pathway analysis identified 51 significant enrichment pathways, which mainly included systemic lupus erythematosus, osteoclast differentiation, cytokine-cytokine receptor interaction, and primary immunodeficiency. Based on the PPI network, the study identified the top 10 hub genes involved in CLE, which were CXCL10, CCR7, FPR3, PPARGC1A, MMP9, IRF7, IL2RG, SOCS1, ISG15, and GSTM3. By comparison between subtypes, the results showed that ACLE had the least DEGs, while CCLE showed the most gene and functional changes. CONCLUSION The identified hub genes and functional pathways found in this study may expand our understanding on the underlying pathogenesis of CLE and provide new insights into potential biomarkers or targets for the diagnosis and treatment of CLE. Key Points • The bioinformatics analysis based on CLE patients and healthy controls was performed and 1160 DEGs were identified • The 1160 DEGs were mainly enriched in biological processes related to immune responses, including innate immune response, type I interferon signaling pathway, interferon-γ-mediated signaling pathway, positive regulation of T cell proliferation, regulation of immune response, antigen processing, and presentation via MHC class Ib and so on • KEGG pathway enrichment analysis indicated that DEGs were mainly enriched in several immune-related diseases and virus infection, including systemic lupus erythematosus, primary immunodeficiency, herpes simplex infection, measles, influenza A, and so on • The hub genes such as CXCL10, IRF7, MMP9, CCR7, and SOCS1 may become new markers or targets for the diagnosis and treatment of CLE.

Long-Term Outcome in Systemic Lupus Erythematosus; Knowledge from Population-Based Cohorts. J Clin Med 2021; 10:jcm10194306. [PMID: 34640322 PMCID: PMC8509465 DOI: 10.3390/jcm10194306] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 09/06/2021] [Accepted: 09/13/2021] [Indexed: 12/16/2022] Open
Abstract
Background: Accurate knowledge of outcomes in Systemic Lupus Erythematosus (SLE) is crucial to understanding the true burden of the disease. The main objective of this systematic review was to gather all population-based studies on mortality, end-stage renal disease (ESRD) and cancer in SLE. Method: We performed a systematic literature search in two electronic databases (MEDLINE and Embase) to identify all population-based articles on SLE and survival, mortality, ESRD and cancer. The SLE diagnosis had to be verified. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). Results: We included 40/1041 articles on mortality (27), ESRD (11) and cancer (3), of which six were defined as inception studies. In the total SLE cohort, the standardized mortality ratio ranged from 1.9 to 4.6. Cardiovascular disease was the most frequent cause of death in studies with follow-up times over 15 years. SLE progressed to ESRD in 5–11% of all SLE patients. There are no data supporting increased cancer incidence from population-based inception cohorts. Conclusion: There is a need for more population-based studies on outcomes of SLE, especially inception studies, with the use of control groups and follow-up times over 15 years.

Abstract
BACKGROUND Thalidomide has shown exceptional results in systemic/cutaneous lupus erythematosus(SLE/CLE). Recently, lenalidomide has been also prescribed for SLE/CLE treatment. Literature regarding efficacy/adverse events for these drugs is scarce with a single systematic review and meta-analysis focused solely on thalidomide for refractory cutaneous lupus subtypes. OBJECTIVE We, therefore, addressed in this narrative review the efficacy/adverse effects of thalidomide and lenalidomide for SLE and CLE. In addition, we provide a specialist approach for clinical practice based on the available evidence. RESULTS Efficacy of thalidomide for refractory cutaneous lupus treatment was demonstrated by several studies, mostly retrospective with small sample size(≤20). The frequency of peripheral polyneuropathy is controversial varying from 15-80% with no consistent data regarding cumulative dose and length of use. Drug withdrawn results in clinical partial/complete reversibility for most cases (70%). For lenalidomide, seven studies (small sample sizes) reported its efficacy for SLE/CLE with complete/partial response in all patients with a mean time to response of 3 months. Flare rate varied from 25-75% occurring 0.5-10 months after drug withdrawn. There were no reports of polyneuropathy/worsening of previous thalidomide-induced neuropathy, but most of them did not perform nerve conduction studies. Teratogenicity risk exist for both drugs and strict precautions are required. CONCLUSIONS Thalidomide is very efficacious as an induction therapy for patients with severe/refractory cutaneous lupus with high risk of scarring, but its longstanding use should be avoided due to neurotoxicity. Lenalidomide is a promising drug for skin lupus treatment, particularly regarding the apparent lower frequency of nerve side effects.

Abstract
AIM This study is a longitudinal multicenter study which aims to find the prevalence, the demographic data, survival and mortality rates of patients with systemic lupus erythematosus (SLE) in Oman. METHOD All Omani patients, pediatrics and adults diagnosed with SLE, who fulfill either the 1997 American College of Rheumatology or Systemic Lupus International Collaborating Clinics classifications criteria for SLE were included from January 2006 till February 2020. RESULTS In total 1160 patients were included in this cohort. Data analysis showed that patient's ages ranged from 2-82 years with female predominance and female-to-male ratio of 7:1 (87.7% female,12.3% male). The mean prevalence of SLE among different age groups was 38.8 (range 5-63 per 100 000 inhabitants). The mortality rate was found to be 5%. Male patients had significantly higher mortality rate than females (7.6% vs 5.4%, P value = .04). Sepsis was the commonest cause of mortality (34%). The coexistence of systemic sclerosis correlates significantly with death (P = .002). Survival analysis in our data showed 5, 10, 20, 40-year survival rates of 100%, 100%, 99% and 90% respectively for antinuclear antibody (ANA) positive patients and lower survival rate for ANA negative patients with 5,10, 20, 40-year survival rates of 100, 99%, 99% and 75%, respectively. CONCLUSION This study showed that the mean prevalence of SLE in Oman to be 38.8 (range 5-63) per 100 000 inhabitants. The 40-year survival rate among patients with positive ANA was found to be 90%, while patients with negative ANA had worse survival outcomes.

Abstract
Die vielen klinischen Varianten des kutanen Lupus erythematodes (CLE) können solitär oder im Rahmen eines systemischen Lupus erythematodes (SLE) auftreten, auf dessen Vorkommen regelmäßig gescreent werden muss. Neben dem weiblichen Geschlecht und genetischen Faktoren stellen Sonnenexposition, Rauchen und manche Medikamente Risikofaktoren dar. Die wichtigsten CLE-Formen sind der akut-kutane LE (z. B. Schmetterlingserythem, generalisiert makulopapulös, enoral), der subakut-kutane LE (z. B. anuläre Form) und der chronisch-kutane LE (z. B. vernarbend diskoide Läsionen, Pannikulitis, Chilblain-LE). Die Diagnose beruht vor allem auf der Klinik und der Histopathologie, hinzu kommen autoimmunserologische Befunde und die direkte Immunfluoreszenz. Milde CLE-Formen können lokal therapiert werden. Reicht dies nicht aus, ist neben einem Steroidstoß Hydroxychloroquin die Systemtherapie der Wahl. Erweiterte therapeutische Optionen stellen Methotrexat, Retinoide, Dapson, Mycophenolat Mofetil, Azathioprin, Thalidomid, Belimumab und Rituximab dar. Alle CLE-Therapien sind off-label. Eine Aktualisierung der Impfungen sollte nach Möglichkeit vor Beginn einer Immunsuppression stattfinden. Zur Objektivierung des therapeutischen Ansprechens eines CLE empfiehlt sich das regelmäßige Scoring mittels RCLASI (Revised CLE Disease Area and Severity Index). Präventiv ist Sonnenschutz (Cremen, Kleidung, Reiseziele) von höchster Wichtigkeit, da Sonnenexposition Schübe provozieren kann. Ein LE stellt keine Kontraindikation gegen eine Schwangerschaft (SS) dar, jedoch sollte diese nicht in einem Schub eintreten, da dies das Risiko für Fetus und Mutter erhöht. Therapeutisch kommen während einer SS v. a. Steroide, Hydroxychloroquin, Dapson und Azathioprin in Betracht.

Abstract
OBJECTIVES To investigate the relationship between smoking history and pack-year exposure on the rate of end-organ damage in systemic lupus erythematosus (SLE). METHODS The SLE incident cohort included patients who met American College of Rheumatology (ACR) 1997 or SLE International Collaborating Clinics (SLICC) 2012 SLE criteria and had rheumatology encounters at a US academic institution (2008-16). The primary outcome was median time to SLICC/ACR damage index (SLICC/ACR-DI) increase or death. Main explanatory variables were smoking status and pack-years. Covariates included age, sex, race, ethnicity, receipt of Medicaid, neighborhood area deprivation index, and baseline SLE damage. Damage increase-free survival was evaluated by smoking status and pack-years using Kaplan-Meier and Cox proportional hazards methods. RESULTS Patients of Black race and Medicaid recipients were more commonly current smokers (p's < 0.05). Former smokers were older and more likely to have late-onset SLE (54% versus 33% of never and 29% of current smokers, p = 0.001). Median time to SLICC/ACR-DI increase or death was earlier in current or former compared to never smokers (4.5 and 3.4 versus 9.0 yrs; p = 0.002). In multivariable models, the rate of damage accumulation was twice as fast in current smokers (HR 2.18; 1.33, 3.57) and smokers with a >10 pack-year history (HR 2.35; 1.15, 3.64) versus never smokers. CONCLUSIONS In this incident SLE cohort, past or current smoking predicted new SLE damage 4-5 years earlier. After adjustment, current smokers and patients with a pack-year history of >10 years accumulated damage at twice the rate of never smokers.

Abstract
To estimate the prevalence and incidence rate of systemic lupus erythematosus (SLE) in Taiwan by using a population-based longitudinal database from 2001 to 2011. We conducted a longitudinal Health Insurance Database (LHID) containing 1,000,000 beneficiaries' records for calculation of prevalence and incidence rate of SLE from 2001-2011. The overall prevalence of SLE in Taiwan in 2011 is 8.11 per 10,000 people with 14.3 per 10,000 people in female and 1.62 per 10,000 people in male. The overall incidence rate of SLE is 0.74-1 per 10,000 person-years with 1.09-1.76 per 10,000 person-years in female and 0.12-0.25 per 10,000 person-years in male. The highest prevalence rate was observed at 40-49 age group in females. There were no significant differences in the overall prevalence among the urban, suburban and rural area in Taiwan while the relative risk is higher in male population living in rural area (RR 1.36, 95% C.I. 1.03-1.79, p = 0.0303). The highest income group has a lower relative risk for the prevalence of SLE (RR 0.83, 95% C.I. 0.71-0.97, p = 0.0197). The incidence rate of SLE in male in the rural area is also higher than the urban area (RR 2.34, 95% C.I. 1.3-4.22, p = 0.0046). Our study covers the longest period among the nation-wide population studies of SLE in Taiwan. The prevalence was increasing especially in the elderly.

Abstract
BACKGROUND Lupus erythematosus is an autoimmune disease with significant morbidity and mortality. Cutaneous disease in systemic lupus erythematosus (SLE) is common. Many interventions are used to treat SLE with varying efficacy, risks, and benefits. OBJECTIVES To assess the effects of interventions for cutaneous disease in SLE. SEARCH METHODS We searched the following databases up to June 2019: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, Wiley Interscience Online Library, and Biblioteca Virtual em Saude (Virtual Health Library). We updated our search in September 2020, but these results have not yet been fully incorporated. SELECTION CRITERIA We included randomised controlled trials (RCTs) of interventions for cutaneous disease in SLE compared with placebo, another intervention, no treatment, or different doses of the same intervention. We did not evaluate trials of cutaneous lupus in people without a diagnosis of SLE. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Primary outcomes were complete and partial clinical response. Secondary outcomes included reduction (or change) in number of clinical flares; and severe and minor adverse events. We used GRADE to assess the quality of evidence. MAIN RESULTS Sixty-one RCTs, involving 11,232 participants, reported 43 different interventions. Trials predominantly included women from outpatient clinics; the mean age range of participants was 20 to 40 years. Twenty-five studies reported baseline severity, and 22 studies included participants with moderate to severe cutaneous lupus erythematosus (CLE); duration of CLE was not well reported. Studies were conducted mainly in multi-centre settings. Most often treatment duration was 12 months. Risk of bias was highest for the domain of reporting bias, followed by performance/detection bias. We identified too few studies for meta-analysis for most comparisons. We limited this abstract to main comparisons (all administered orally) and outcomes. We did not identify clinical trials of other commonly used treatments, such as topical corticosteroids, that reported complete or partial clinical response or numbers of clinical flares. Complete clinical response Studies comparing oral hydroxychloroquine against placebo did not report complete clinical response. Chloroquine may increase complete clinical response at 12 months' follow-up compared with placebo (absence of skin lesions) (risk ratio (RR) 1.57, 95% confidence interval (CI) 0.95 to 2.61; 1 study, 24 participants; low-quality evidence). There may be little to no difference between methotrexate and chloroquine in complete clinical response (skin rash resolution) at 6 months' follow-up (RR 1.13, 95% CI 0.84 to 1.50; 1 study, 25 participants; low-quality evidence). Methotrexate may be superior to placebo with regard to complete clinical response (absence of malar/discoid rash) at 6 months' follow-up (RR 3.57, 95% CI 1.63 to 7.84; 1 study, 41 participants; low-quality evidence). At 12 months' follow-up, there may be little to no difference between azathioprine and ciclosporin in complete clinical response (malar rash resolution) (RR 0.83, 95% CI 0.46 to 1.52; 1 study, 89 participants; low-quality evidence). Partial clinical response Partial clinical response was reported for only one key comparison: hydroxychloroquine may increase partial clinical response at 12 months compared to placebo, but the 95% CI indicates that hydroxychloroquine may make no difference or may decrease response (RR 7.00, 95% CI 0.41 to 120.16; 20 pregnant participants, 1 trial; low-quality evidence). Clinical flares Clinical flares were reported for only two key comparisons: hydroxychloroquine is probably superior to placebo at 6 months' follow-up for reducing clinical flares (RR 0.49, 95% CI 0.28 to 0.89; 1 study, 47 participants; moderate-quality evidence). At 12 months' follow-up, there may be no difference between methotrexate and placebo, but the 95% CI indicates there may be more or fewer flares with methotrexate (RR 0.77, 95% CI 0.32 to 1.83; 1 study, 86 participants; moderate-quality evidence). Adverse events Data for adverse events were limited and were inconsistently reported, but hydroxychloroquine, chloroquine, and methotrexate have well-documented adverse effects including gastrointestinal symptoms, liver problems, and retinopathy for hydroxychloroquine and chloroquine and teratogenicity during pregnancy for methotrexate. AUTHORS' CONCLUSIONS Evidence supports the commonly-used treatment hydroxychloroquine, and there is also evidence supporting chloroquine and methotrexate for treating cutaneous disease in SLE. Evidence is limited due to the small number of studies reporting key outcomes. Evidence for most key outcomes was low or moderate quality, meaning findings should be interpreted with caution. Head-to-head intervention trials designed to detect differences in efficacy between treatments for specific CLE subtypes are needed. Thirteen further trials are awaiting classification and have not yet been incorporated in this review; they may alter the review conclusions.

Abstract
Background Subacute cutaneous lupus erythematosus (SCLE) lacks consensus diagnostic criteria and the pathogenesis is poorly understood. There are increasing reports of SCLE induced by monoclonal antibodies (mAbs), but there are limited data on the aetiology, clinical characteristics and natural course of this disease. Methods We devised a set of diagnostic criteria for SCLE in collaboration with a multinational, multispecialty panel. This systematic review employed a two-layered search strategy of five databases for cases of mAb-induced SCLE (PROSPERO registered protocol CRD42019116521). To explore the relationship between relative mAb use and the number of SCLE cases reported, the estimated number of mAb users was modelled from 2013 to 2018 global commercial data and estimated annual therapy costs. Results From 40 papers, we identified 52 cases of mAb-induced SCLE, occurring in a cohort that was 73% female and with a median age of 61 years. Fifty percent of cases were induced by anti-tumour necrosis factor (TNF)-ɑ agents. A median of three drug doses preceded SCLE onset and the lesions lasted a median of 7 weeks after drug cessation. Oral and topical corticosteroids were most frequently used. Of the licensed mAbs, adalimumab, denosumab, rituximab, etanercept and infliximab were calculated to have the highest relative number of yearly users based on global sales data. Comparing the number of mAb-induced SCLE cases with estimated yearly users, the checkpoint inhibitors pembrolizumab and nivolumab showed strikingly high rates of SCLE relative to their global use, but ipilimumab did not. Conclusion We present the first systematic review characterising mAb-induced SCLE with respect to triggers, clinical signs, laboratory findings, prognosis and treatment approaches. We identify elevated rates associated with the use of checkpoint inhibitors and anti-TNFɑ agents.

Abstract
BACKGROUND Age at disease onset may modulate systemic lupus erythematosus (SLE), but its relation to cutaneous/extracutaneous manifestation remains understudied. OBJECTIVE To compare the cutaneous, systemic features, laboratory characteristics, and disease severity between late- and adult-onset SLE patients. METHODS Analyses of the cutaneous, systemic involvement, laboratory investigations, SLE disease activity index 2000 (SLEDAI-2K), and disease damage were performed to compare between groups. RESULTS Of 1006 SLE patients, 740 and 226 had adult- (15-50 years) and late-onset (>50 years), respectively. Among 782 with cutaneous lupus erythematosus (CLE), acute CLE (ACLE) and chronic CLE (CCLE) were more common in the adult- and late-onset SLE, respectively (p = 0.001). Multivariable logistic regression analysis demonstrated that male patients and skin signs, including papulosquamous subacute CLE, discoid lupus erythematosus, and lupus profundus, were associated with late-onset SLE (all p < 0.05). Late-onset SLE had lower lupus-associated autoantibodies, and systemic involvement (all p < 0.05). ACLE, CCLE, mucosal lupus, alopecia, and non-specific lupus were related to higher disease activity in adult-onset SLE (all p < 0.001). There was no difference in the damage index between the two groups. CONCLUSIONS Late-onset SLE had a distinct disease expression with male predominance, milder disease activity, and lower systemic involvement. Cutaneous manifestations may hold prognostic values for SLE.

Abstract
OBJECTIVE Discoid lupus erythematosus (DLE) is the most common category of chronic cutaneous lupus erythematosus, where the pathological process is proved to be closely associated with immunity. This bioinformatic analysis sought to identify key biomarkers and to perform immune infiltration analysis in the skin biopsy samples of DLE. METHODS GSE120809, GSE100093, GSE72535, GSE81071 were used as the data source of gene expression profiles, altogether containing 79 DLE samples and 47 normal controls (NC). Limma package was applied to identify differentially expressed genes (DEGs) and additional Gene Ontology (GO) together with The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were done. Protein-protein interaction network (PPI) was constructed using STRING and Cytoscape. Hub genes were selected by CytoHubba. Finally, immune filtration analysis was finished by the CIBERSORT algorithm, and comparisons between the two groups were accomplished. RESULTS A total of 391 DEGs were identified, which were composed of 57 up-regulated genes and 334 down-regulated genes. GO and KEGG enrichment analyses revealed that DEGs were closely related with different steps in the immune response. Top 10 hub genes included GBP2, HLA-F, IFIT2, RSAD2, ISG15, IFIT1, IFIT3, MX1, XAF1 and IFI6. Immune filtration analysis from CIBERSORT had found that compared with NC, DLE samples had higher percentages of CD8+ T cells, T cells CD4 memory activated, T cells gamma delta, macrophages M1 and lower percentages of T cells regulatory, macrophages M2, dendritic cells resting, mast cells resting, mast cells activated. CONCLUSION This bioinformatic study selected key biomarkers from the contrast between DLE and NC skin samples and is the first research to analyze immune cell filtration in DLE.

Shared inflammatory and skin-specific gene signatures reveal common drivers of discoid lupus erythematosus in canines, humans and mice. CURRENT RESEARCH IN IMMUNOLOGY 2021; 2:41-51. [PMID: 35492392 PMCID: PMC9040131 DOI: 10.1016/j.crimmu.2021.03.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 03/19/2021] [Accepted: 03/21/2021] [Indexed: 12/29/2022] Open
Abstract
Autoimmune skin diseases are complex and are thought to arise from a combination of genetics and environmental exposures, which trigger an ongoing immune response against self-antigens. Companion animals including cats and dogs are known to develop inflammatory skin conditions similar to humans and share the same environment, providing opportunities to study spontaneous disease that encompasses genetic and environmental factors with a One Health approach. A strength of comparative immunology approaches is that immune profiles may be assessed across different species to better identify shared or conserved pathways that might drive inflammation. Here, we performed a comparative study of skin from canine discoid lupus erythematosus (DLE) using NanoString nCounter technology. We compared these gene expression patterns to those of human DLE and a mouse model of cutaneous lupus. We found strong interferon signatures, with CXCL10, ISG15, and an S100 gene family member among the highest, most significant DEGs upregulated across species. Cell type analysis revealed marked T-cell and B-cell infiltration. Interestingly, canine DLE samples also recapitulated downregulated skin homeostatic genes observed in human DLE. We conclude that spontaneous DLE in dogs captures many features that are present in human disease and may serve as a more complete model for conducting further genomic and/or transcriptomic studies. Canine DLE lesions express known drivers of pathogenesis including CXCL10, IFNG, FAS. Enrichment of key cell types, including T, B, NK cells, is observed in canine DLE. Canine, mouse and human DLE share similar proinflammatory profiles. Canine DLE exhibits downregulated skin homeostatic and immune regulatory genes.

Abstract
Introduction Cutaneous manifestations are central to the primary diagnosis of systemic lupus erythematosus (SLE). However, information on the clinical, histopathologic, and direct immunofluorescence (DIF) features among subtypes of cutaneous lupus erythematosus (CLE), as well as longitudinal prospective observational study to evaluate the natural history and the progression to SLE, is lacking among Asians. Our objectives are to summarize the differences in the clinical, histopathologic, and DIF characteristics and serological profiles between various subtypes of CLE, and to provide its natural history and the association with disease activity in our Asian population. Methods A prospective observational study on CLE patients was performed between May 2016 and May 2020. Patients underwent full physical/dermatologic examination, skin biopsy for histology, and DIF. Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) scores and laboratory data were evaluated. Time schedule and characteristics for resolution and/or the disease progression to SLE were recorded in subsequent follow-ups. Results Of 101 biopsy-proven CLE patients, 25 had acute CLE (ACLE), 8 had subacute CLE (SCLE), 39 had chronic CLE (CCLE) only, 22 had CCLE with SLE, and 7 had LE-nonspecific cutaneous lesions only. Patients with exclusive CLE showed lower female preponderance, serological abnormalities, and correlation to systemic disease. However, when CLE was accompanied with any LE-nonspecific cutaneous manifestations, they were associated with high antinuclear antibody (ANA) titer, renal, hematologic, joint involvement, and greater SLEDAI score. Of 207 biopsy sections, SCLE/CCLE regardless of systemic involvement showed significantly higher percentage of superficial/deep perivascular and perieccrine infiltration than ACLE. On DIF, deposition of multiple immunoreactants was associated with higher systemic disease. Approximately 10% of CLE-only patients later developed SLE but had mild systemic involvement. Conclusion Our findings support that each CLE subtype has a diverse and unique character. Comprehensive understanding of the differences among CLE subtypes is important for achieving the correct diagnosis and providing appropriate disease monitoring and management.

Abstract
Introduction Discoid lupus erythematosus (DLE) is the most common form of cutaneous lupus erythematosus. It is a chronic, scar-forming, photosensitive autoimmune dermatosis presenting with erythematous and scaly lesions. Predisposed areas include sun-exposed areas like the nose, forehead, and cheeks, as well as the upper body and extremities. The histological findings are typical, with interface dermatitis. Immunoglobulin M (IgM) and immunoglobulin G (IgG) are the most common deposits in the dermoepidermal junction of the involved skin. The most common treatments used are sunscreens, topical corticosteroids, and antimalarials. Immunosuppressive agents, thalidomide, dapsone, and retinoids can be used in refractory cases. The aim of this study was to study the clinicopathologic patterns of DLE in patients presenting to the Institute of Skin Diseases in Sindh, Karachi. Methods A total of 53 consecutive patients with DLE meeting the inclusion criteria were evaluated between February 18, 2018 to March 2, 2019 at the Institute of Skin Diseases. Patients with clinical suspicion of DLE were evaluated and studied prospectively after written informed consent was obtained. Information was then collected from their medical histories, physical examination records, and laboratory investigation reports. Results A total of 53 consecutive patients with clinical and/or histological diagnosis of DLE was included in this study, out of which 75.5% (40) were females with a male to female ratio of 1:3.1. The mean age of the patients at the time of presentation was 36.02 ± 10.04 years, ranging from 14 to 65 years. More than half of the patients (35, 66.0%) were under 40 years of age and 20.8% (11) had a positive family history of DLE. DLE was localized in 36 patients (67.9%) and exposure to the ultraviolet radiation (UVR) was found to be the most frequent induced factor in 46 patients (86.8%), followed by stress which was observed in 14 patients (26.4%). The distribution of commonly affected sites were the face (81.1%), the limbs (71.7%), and the scalp (48.4%) of the patients. Serology antinuclear antibody (ANA) was positive in 56.6% and serology anti-double-stranded deoxyribonucleic acid antibodies (anti-dsDNA) were positive in 45.3% of patients. Smoking, as an induced factor, was more commonly observed among male patients as compared to the female patients with a proportion of 53.8% vs. 2.5%, p < 0.001, while stress was more common among female patients with a proportion of 35% vs. 0%, p = 0.013, respectively. Histopathology with direct immunofluorescence was done in 33 cases which included cases with negative serology or where the diagnosis was in doubt clinically. The main histopathological features observed were periadnexal and perivascular dermal infiltrates, basal cells vacuolization, epidermal atrophy, hyperkeratosis, and follicular plugging. The commonest morphological form observed was the classic discoid plaque form. Conclusion Clinical patterns of DLE in our population comprises of female dominance. Exposure to UVR was the leading inducing factor. The face and limbs were the most commonly involved sites, and the majority of the patients had localized DLE with positive ANA in more than half of those patients. The importance of limiting ultraviolet radiation exposure and toxins (drugs and smoking) should be emphasized in our population.

Abstract
PURPOSE OF REVIEW Understanding the pathogenesis of cutaneous lupus erythematosus (CLE) is an important step in developing new medications and providing effective treatment to patients. This review focuses on novel research within CLE pathogenesis, as well as some of the medications being developed based on this knowledge. RECENT FINDINGS The subtle differences between systemic lupus erythematosus (SLE) and CLE pathogenesis are highlighted by differences in the circulating immune cells found in each disease, as well as the specific pathways activated by ultraviolet light. Plasmacytoid dendritic cells and the related type I interferon pathway are major components of CLE pathogenesis, and as such, therapies targeting components of this pathway have been successful in recent clinical trials. B cell-depleting therapies have shown success in SLE; however, their role in CLE is less clear. Understanding the differences between these manifestations of lupus allows for the development of therapies that are more effective in skin-specific disease. Discovering key pathways in CLE pathogenesis is critical for understanding the clinical features of the disease and ultimately developing new and effective therapies.

Abstract
BACKGROUND Schizophrenia is a debilitating neuropsychiatric condition that affects 0.5% of the North American population. Skin disease in schizophrenia has not been well described. Identifying skin diseases that are commonly comorbid with schizophrenia may help clinicians address the burden of skin disease in patients with schizophrenia. SUMMARY We conducted a nonsystematic review of the literature to identify skin diseases that may be associated with schizophrenia. We searched MEDLINE, EMBASE, and PsycINFO for articles published in English from December 2000 through April 2020 using the key words "skin disease" or "dermatological" or "dermatology" and "schizophrenia." Based on our results, we further refined the search terms to include more specific skin diseases. Schizophrenia appears to be associated with a number of skin diseases, including inflammatory dermatoses, autoimmune diseases, and certain genodermatoses. Limitations include being a nonsystematic review and the relative paucity of more rigorous clinical research using longitudinal study designs.

Abstract
INTRODUCTION Between 5 and 25% of patients with cutaneous lupus erythematosus (CLE) can progress to systemic lupus erythematosus (SLE) during the course of the disease. There is no clear predictive guideline for the progression of CLE to SLE. AREAS COVERED Lupus erythematosus (LE), a chronic autoimmune disease, has a wide spectrum of manifestations. On one side of the spectrum is CLE, in which patients only display skin lesions. On the other side of the spectrum is SLE, which develops severe systemic involvement. CLE has even been considered as a separate entity from LE, while CLE is also proposed to be associated with SLE. In this review, the authors will describe the relationship between CLE and SLE; summarize the incidence, risk factors, systemic involvement, and management of patients who transition to SLE. The literature search was conducted mainly through PubMed from March to July 2020. EXPERT OPINION The identification of clinical characteristics and biomarkers in patients facing risk of developing SLE and monitoring the disease on a regular basis are essential to promptly manage and hopefully prevent transition to the systemic form.

Abstract
Knowledge of the etiology of cutaneous lupus is rapidly evolving. Dissection of the pathologic events in lesional skin has led to knowledge of important cell populations and transcriptional changes contributing to disease. Recently, the study of nonlesional skin in patients with systemic lupus has also identified key abnormalities that likely contribute to a propensity for inflammation. These include an elevated type I IFN signature, overproduction of IFNs, and an absence of Langerhans cells. These changes promote aberrant inflammation in response to known triggers of disease, such as UV light. Further research will undoubtedly accelerate our understanding of this disfiguring disease.

Abstract
The cutaneous manifestations of lupus, especially chronic cutaneous lupus erythematosus, are a source of significant morbidity and can negatively impact patient quality of life. While the active inflammatory component of the disease may be adequately treated, patients are frequently left with residual skin damage and disfiguring aesthetic deficits. Dermatologists lack guidelines regarding the use and safety of various reconstructive and cosmetic interventions in this patient population. Laser treatments are largely avoided in the lupus population because of the possible photodamaging effects of ultraviolet and visible light. Similarly, given the autoimmune nature of this disease, some physicians avoid injectable treatment and grafts because of the concern for disease reactivation via antigenic stimulation. In the second article in this continuing medical education series we compile available data on this topic with the goal of providing evidence-based guidance on the cosmetic treatment of patients with lupus erythematosus with a focus on chronic cutaneous lupus erythematosus.

Abstract
INTRODUCTION The risk factors for systemic autoimmune diseases (SAD) in gastric disease patients with proton pump inhibitor (PPI) use are still unclear. This study discussed this relationship in an Asian population. METHODS Patients without a prior history of SAD were identified from Taiwan's National Health Insurance Research Database between January 1, 2000, and December 31, 2010. Cox regression models were applied to estimate the hazard ratio (HR) with 95% confidence interval [CI] of SAD. The cumulative PPI dosage was stratified by quartiles of defined daily doses and adjusted for baseline disease risk score which served as the primary variables compared against no PPI use. RESULTS We analyzed the data of 51,291 participants aged 18 years or older and free of SAD at baseline. PPI users (n = 17,938) had a significantly increased risk of SAD over non-PPI users. There was a significantly higher risk of developing SAD in older age groups. A significant dose-dependent association was observed between cumulative PPI use and the risk of SAD. Female PPI users had significantly higher risk of developing SAD. In patients who received PPI, the autoimmune disease with significantly higher incidence was Sjögren syndrome (SjS) (adjusted HR [aHR] 1.82, 95% CI, 1.02-3.27) and rheumatoid arthritis (RA) (aHR, 2.19, 95% CI, 1.19-4.01). CONCLUSION This study found PPI users to be associated with an increased risk of SAD. Older age or cumulative PPI use was significantly associated with SAD, and the highest incidence was SjS and RA among gastric disease patients who received PPI. Key Points • This nationwide long-term cohort study found PPI users to be associated with an increased risk of rheumatoid arthritis and Sjögren syndrome in Taiwan. • This finding may help with clinical risk evaluation and will inform further investigation of the pathogenesis between autoimmune diseases and PPI use.

Abstract
Monitoring the activity of systemic lupus erythematosus (SLE) is important to patient management. Blood biochemical indexes are commonly assessed but are both time demanding and traumatizing. In this study, a noninvasive and real-time spatial-spectral data tool was used to monitor SLE patients through rash spectral data. To build the relationship between the rash spectrum changes and changes in the patients' status, a snapshot hyperspectral Fourier transform imaging spectrometer was built to monitor the rash reflectance changes of hospitalized SLE patients. A simple rash activity index (RAI) which was normally distributed with the doctor's visual rating of rash severity was calculated from hyperspectral images. The sensitivity of the change in RAI is higher than complement 3/4 levels. RAI and anti-dsDNA antibodies both decreased as the patients recovered. Anti-dsDNA and complement 3/4 were important indicators of SLE activity suggesting that the RAI directly correlated with patient status. The snapshot spectrometer therefore provides an auxiliary method to monitor SLE disease.

A Missense Variant Affecting the C-Terminal Tail of UNC93B1 in Dogs with Exfoliative Cutaneous Lupus Erythematosus (ECLE). Genes (Basel) 2020; 11:E159. [PMID: 32028618 PMCID: PMC7074252 DOI: 10.3390/genes11020159] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 01/27/2020] [Accepted: 01/31/2020] [Indexed: 01/20/2023] Open
Abstract
Cutaneous lupus erythematosus (CLE) in humans encompasses multiple subtypes that exhibit a wide array of skin lesions and, in some cases, are associated with the development of systemic lupus erythematosus (SLE). We investigated dogs with exfoliative cutaneous lupus erythematosus (ECLE), a dog-specific form of chronic CLE that is inherited as a monogenic autosomal recessive trait. A genome-wide association study (GWAS) with 14 cases and 29 controls confirmed a previously published result that the causative variant maps to chromosome 18. Autozygosity mapping refined the ECLE locus to a 493 kb critical interval. Filtering of whole genome sequence data from two cases against 654 controls revealed a single private protein-changing variant in this critical interval, UNC93B1:c.1438C>A or p.Pro480Thr. The homozygous mutant genotype was exclusively observed in 23 ECLE affected German Shorthaired Pointers and an ECLE affected Vizsla, but absent from 845 controls. UNC93B1 is a transmembrane protein located in the endoplasmic reticulum and endolysosomes, which is required for correct trafficking of several Toll-like receptors (TLRs). The p.Pro480Thr variant is predicted to affect the C-terminal tail of the UNC93B1 that has recently been shown to restrict TLR7 mediated autoimmunity via an interaction with syndecan binding protein (SDCBP). The functional knowledge on UNC93B1 strongly suggests that p.Pro480Thr is causing ECLE in dogs. These dogs therefore represent an interesting spontaneous model for human lupus erythematosus. Our results warrant further investigations of whether genetic variants affecting the C-terminus of UNC93B1 might be involved in specific subsets of CLE or SLE cases in humans and other species.

[PMID: 32042465 PMCID: PMC6976739 DOI: 10.5001/omj.2020.02] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 03/25/2019] [Indexed: 01/01/2023] Open
Abstract
Objectives We sought to determine the prevalence of immune-mediated skin disorders (IMDs), their oral manifestations, and the related comorbidity among Omani patients with IMDs attending the outpatient Department of Dermatology and Dental Clinic at Al Nahdha Hospital, Muscat. Methods We conducted a retrospective study of 236 newly-diagnosed patients with IMDs who attended the outpatient clinic between September 2014 and September 2017. Data, such as age, sex, investigations, diagnosis, comorbidity, and associated oral manifestations of the affected individuals, were collected from the hospital health information system. Results Of the 236 diagnosed cases of IMD, lichen planus substantially comprised over half of the total cases (59.7%). This was followed by relatively fewer cases of discoid lupus erythematosus (11.0%), systemic lupus erythematosus (10.2%), and erythema multiforme (8.1%). Pemphigus vulgaris and bullous pemphigus comprised only 3.0% and 4.2% of the total studied cases, respectively. The other less common disorders found in our study were toxic epidermal necrolysis (1.7%), pemphigus foliaceus (1.3%), and gestational pemphigoid (0.8%). Oral mucosal involvement was seen more commonly with lichen planus (78.7%), pemphigus vulgaris (71.4%), and erythema multiforme (75.0%), while systemic lupus erythematosus and discoid lupus erythematosus were shown to appear with more comorbidities compared to the other skin disorders studied. Conclusions Several IMDs have considerable oral involvement. These oral manifestations of the diseases may be overlooked by other specialists leading to a delay in the diagnosis and its management. In order to circumvent this delay, the analysis and evaluation of a disease need to be done by a team comprising of a dental surgeon, dermatologist, and an oral medicine specialist.
