Kingsmore KM, Zent JM, Lipsky PE. Clinical management of lupus in the United States: A claims-based analysis. Semin Arthritis Rheum 2024; 68:152472. [PMID: 38875804 DOI: 10.1016/j.semarthrit.2024.152472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 05/16/2024] [Accepted: 05/17/2024] [Indexed: 06/16/2024]
Abstract
OBJECTIVES To understand the evaluation and management of patients coded with lupus in the broad clinical community in the United States. METHODS Claims data for diagnoses, procedures, medications, and physician specialties were evaluated for three lupus cohorts [lupus nephritis (LN), systemic lupus erythematosus excluding LN (SLE), and cutaneous lupus erythematosus excluding SLE and LN (CLE)] using the EVERSANA claims databases. Identification of patients was based upon the occurrence of lupus-specific codes, with the requirement that a single patient receive a lupus-related ICD code twice within a six-month period. RESULTS Using ICD codes, we were able to identify 28,372 patients coded with LN, 82,744 patients coded with SLE, and 13,920 patients coded with CLE, and subsequently evaluate the journey of patients in each group in the year before and after being coded as having a diagnosis of lupus. For the three lupus cohorts, the basis of diagnosis was not always apparent, as clinical features of lupus were not often obtained, autoantibody testing was not usual, biopsies were uncommon and subspecialty involvement was not routine. In addition, a significant increase in laboratory testing, non-lupus diagnoses, emergency department visits and cost during the year before receiving a lupus code suggested uncertainty in disease recognition. Nevertheless, these patients received two separate lupus coding events within a six-month period, supporting a sustained or repeated diagnosis of lupus by the evaluating clinicians. When compared, the three lupus cohorts differed with regard to frequency of laboratory testing, subspecialty care, skin and renal biopsies, and medication management. Moreover, there was an increase in the cost of care of patients coded with lupus compared to a reference patient population both during the year before and after being coded with a diagnosis of lupus. CONCLUSION The data present a comprehensive report of the care of patients coded as having a diagnosis of lupus in the United States, including those outside of specialty centers. Despite the unclear basis of diagnosis in some patients, evaluation and management of patients coded as having a diagnosis of lupus in the general care community does not closely follow the recommended guidelines set forth by professional societies.

Abstract
The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this consensus provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes.

Abstract
Overlap syndromes are diseases that meet the criteria of two or more rheumatic diseases. In this case report, a woman in her 20s presented with a constellation of symptoms, including skin thickening, Raynaud's phenomenon, hypertension, absent pulse in both lower limbs with bilateral renal artery bruit. The antinuclear antibody profile revealed Scl-70 positivity. CT thorax identified early interstitial lung disease, and nailfold capillaroscopy showed severe capillary loss. CT angiogram features were suggestive of Takayasu arteritis. Notably, there have been only four documented cases of systemic sclerosis coexisting with Takayasu arteritis, highlighting the rarity of this overlap syndrome. The diagnosis of overlap syndrome was made after a thorough history recording and clinical examination. In the presence of bilateral renal artery stenosis, managing the scleroderma renal crisis may be challenging . This patient received treatment with mycophenolate mofetil and oral corticosteroids, aiming to address both systemic sclerosis and Takayasu arteritis effectively.

Prevalence and Characteristics of Patients With Systemic Sclerosis Fulfilling the 2019 EULAR/American College of Rheumatology Classification Criteria for Systemic Lupus Erythematosus. Arthritis Care Res (Hoboken) 2024; 76:311-317.

Abstract
OBJECTIVE There is limited literature describing the overlap of systemic sclerosis (SSc) and systemic lupus erythematosus (SLE), and the studies have employed a range of case definitions. Our study used the new EULAR/American College of Rheumatology (ACR) SLE classification criteria to define SSc-SLE cases among our center's SSc cohort. METHODS This is a single-center, retrospective study of a previously described cohort of patients with SSc. Patient data were re-abstracted to evaluate for fulfillment of the 2019 EULAR/ACR classification criteria for SLE. Demographic, laboratory, clinical features, and mortality were compared among patients with SSc-SLE and patients with SSc alone. RESULTS Among the 402 patients with SSc that were analyzed, 40 (10%) fulfilled the 2019 EULAR/ACR SLE classification criteria. Neuropsychiatric and renal involvement were rare. An initial SLE diagnosis was purported in 43% of the patients with SSc-SLE and 7% of patients with SSc alone (P < 0.001). Patients with SSc-SLE were more likely to be female, African American, and with limited cutaneous SSc. Anti-U1-RNP antibody positivity prevalence was 30% among patients with SSc-SLE and 6.6% among patients with SSc alone (P < 0.001). Death during follow-up occurred in 12 patients (30%) with SSc-SLE and in 81 patients (22%) with SSc alone, but there was no difference in survival among the groups per log rank test (P = 0.404). CONCLUSION Ten percent of patients with SSc fulfill the 2019 EULAR/ACR classification criteria for SLE. These patients comprise a distinct demographic, serologic, and clinical phenotype but have similar severe SSc-specific end-organ damage and mortality as patients with SSc alone. Patients with SLE with Raynaud phenomenon should be evaluated for SSc-specific autoantibodies and scleroderma organ involvement.

Abstract
Fibrosis is a pathological manifestation in which connective tissue replaces normal one. It can affect many tissues from the skin to internal organs such as the lungs. Manifestations of pulmonary involvement can be pulmonary arterial hypertension or pulmonary fibrosis. The latter one is currently the leading cause of death in various autoimmune diseases, including systemic sclerosis. Our study group consists of 50 patients with systemic sclerosis: 24 with limited cutaneous form and 26 with diffuse cutaneous form. This cohort was compared to 50 healthy controls (age and sex matched); our aim is to explore the distribution of TH17 cells (TH17) as well as regulatory T cells (TREG) and study their correlation with the disease's progress. Our results show an increase for IL17A in patients compared to controls and that this increase is correlated with a specific clinical involvement: Pulmonary fibrosis. This correlation suggests a crucial role of IL17A in fibrosis especially in systemic sclerosis. In addition, we have shown that the percentages of TH17 cells are higher in patients; however, the percentages of TREG cells are similar between patients and controls. A study of TREG cell activity showed that TREG lost suppressive activity by inactivating the FOXP3 transcription factor. This proves that despite their presence, TREG does not adequately carry out their regulatory activity. Finally, we analyzed the correlation between TH17/TREG and clinical damage; the results show a positive correlation with pulmonary involvement proving the role of TH17/TREG balance in induced fibrosis in systemic sclerosis. No significative difference was observed, for all the parameters, between the two different forms of the disease. In conclusion, the results associated with the TH17/TREG scale and their correlations with fibrosis in systemic sclerosis open a way for new tools to manage this autoimmune disease, which up to today has neither treatment nor accurate diagnosis.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a rare auto-immune disease, affecting principally women between 40 and 60 years old. It is caracterised by a cutaneous and visceral fibrosis, an alteration of the microvascular network and the presence of autoantibodies. SSc can be associated with another connectivite tissue disease or to other autoimmune diseases, thus defining the overlap syndrome. The goal of our study is to describe these overlap syndromes. METHODS We have analysed the data of a retrospective and bicentrique cohort, from the internal medicine unit of Hôpital Nord in Marseille and from the internal medicine unit of the Hôpital Sainte-Anne in Toulon, of patients followed for a SSc between January 1st, 2019 and December 1st, 2021. We have collected clinical, imunological features, associated auto-immune and inflammatory diseases with its morbidity and mortality. RESULTS The cohort included 151 patients including 134 limited cutaneous SSc. Fifty-two (34.4%) patients presented at least one associated auto-immune or inflammatory disease. The association of two connectivite tissue diseases including SSc was found in 24 patients (15.9%), a third with Sjögren's syndrome and a third with autoimmune myositis. The principal associated disease to SSc was the autoimmune thyroiditis found in 17 patients (11.3%). The occurrence of complications (hospitalization, long-term oxygene therapy, death) was not significantly different depending on the existence or not of an overlap syndrom. CONCLUSION SSc is often associated with other autoimmune diseases. This interrelation between associated pathologies and SSc, modifying sometimes the evolution of SSc, enhances the need of a personalized follow-up.

Abstract
Systemic sclerosis (SSc) is a heterogeneous disease comprising of a wide spectrum of ages of onset, sex-based differences, ethnic variations, disease manifestations, differential serologic profiles, and variable response to therapy resulting in reduced health-related quality of life, disability, and survival. The ability to subset groups of patients with SSc can assist with refining the diagnosis, guide appropriate monitoring, inform aggressiveness of immunosuppression, and predict prognosis. The ability to subset patients with SSc has several important practical implications for patient care.

Abstract
Systemic sclerosis is a systemic autoimmune rheumatic disease characterized by immune abnormalities, leading to vasculopathy and fibrosis. Autoantibody testing has become an increasingly important part of diagnosis and prognostication. Clinicians have been limited to antinuclear antibody (ANA), antitopoisomerase I (also known as anti-Scl-70) antibody, and anticentromere antibody testing. Many clinicians now have improved access to an expanded profile of autoantibody testing. In this narrative review article, we review the epidemiology, clinical associations, and prognostic value of advanced autoantibody testing in people with systemic sclerosis.

Abstract
Patients with systemic sclerosis and systemic lupus erythematosus serologies present a unique challenge to the clinician when hypertension is detected in the outpatient setting. Treatment choices for non-renal crisis hypertension are different for systemic sclerosis versus systemic lupus erythematosus. Urgent laboratory studies and, in the presence of certain symptoms, imaging assessment are indicated in systemic sclerosis and systemic lupus erythematosus overlap patients with systemic hypertension. Long-term assessment of systemic hypertension may be enhanced by advances in non-contrast imaging that serve as valuable biomarkers for progressive vasculopathy. In this review, the diagnostic approach to systemic sclerosis and systemic lupus erythematosus overlap patients presenting with hypertension is discussed.

Abstract
There is an increasing body of literature suggesting a relationship between environmental factors and the development of systemic sclerosis (SSc). These include occupational exposures, chemical materials, medications, alterations in the microbiome, and dysbiosis. Environmental exposures may impact epigenetic regulation thereby triggering an aberrant immune response resulting in the clinical and serologic phenotype that we diagnose as SSc. Screening and studying putative triggers will not only improve our understanding of the pathogenesis of SSc but also inform the institution for protective measures.

Abstract
Shortening the time to diagnosis and initiating early treatment are imperative to improve outcomes in patients with systemic lupus erythematosus (SLE). The aim of this case-control study, based on the data from the Taiwan’s National Health Insurance Research Database (NHIRD), was to investigate the patterns of diagnoses of disease phenotypes in female patients with SLE up to eight years prior to its definitive diagnosis. The 547 cases were selected from the 2000–2012 NHIRD catastrophic illness datafile and frequency-matched with 2188 controls. The primary diagnosis based on the first ICD-9-CM code for each outpatient visit was converted to Phecodes. Separate regression models, based on least absolute shrinkage and selection operator (lasso) regularization, with seven different lag periods from 1–2 to 7–8 years, were conducted. Results showed that SLE was associated with 46 disease phenotypes in a lag period of 2–3 years, but fewer in other lag periods. A number of SLE-associated disease phenotypes, such as primary thrombocytopenia, thyroid diseases, Raynaud’s syndrome, renal disease, and several infectious diseases, occurred mainly in the first few years prior to SLE diagnosis. In conclusion, SLE should be suspected when the disease phenotypes identified in the present study occurred concomitantly.

Kidney Involvement in Systemic Sclerosis. J Pers Med 2022; 12:jpm12071123. [PMID: 35887620 PMCID: PMC9324204 DOI: 10.3390/jpm12071123] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 07/07/2022] [Accepted: 07/08/2022] [Indexed: 11/30/2022] Open
Abstract
Background: Systemic sclerosis is a chronic multisystem autoimmune disease, characterized by diffuse fibrosis and abnormalities of microcirculation and small arterioles in the skin, joints and visceral organs. Material and Methods: We searched for the relevant articles on systemic sclerosis and kidney involvement in systemic sclerosis in the NIH library of medicine, transplant, rheumatologic and nephrological journals. Results: Half of patients with systemic sclerosis have clinical evidence of kidney involvement. Scleroderma renal crisis represents the most specific and serious renal event associated with this condition. It is characterized by an abrupt onset of moderate to marked hypertension and kidney failure. Early and aggressive treatment is mandatory to prevent irreversible organ damage and death. The advent of ACE-inhibitors revolutionized the management of scleroderma renal crisis. However, the outcomes of this serious complication are still poor, and between 20 to 50% of patients progress to end stage renal disease. Conclusions: Scleroderma renal crisis still represents a serious and life-threatening event. Thus, further studies on its prevention and on new therapeutic strategies should be encouraged.

Abstract
An overlap syndrome is a medical condition which shares features of at least two more widely recognized disorders. Autoimmune connective tissue diseases include systemic lupus erythematosus (SLE), scleroderma, polymyositis, dermatomyositis, rheumatoid arthritis and Sjögren's syndrome where overlap syndrome most commonly seen in combination with SLE and systemic sclerosis (SSc). Sjogren's is an autoimmune exocrinopathy, in which systemic diseases such as arthritis, interstitial lung disease and renal disease may develop in addition to the pathognomonic features such as dry eyes and mouth. The other associated disease with Sjogren's includes sialadenitis. Sialadenitis of the parotid gland is one of the major disorders of salivary gland. This article presents a rare case report of a patient diagnosed with sialadenitis of the parotid gland and associated with progressive SSc/lupus overlap syndrome and secondary Sjogren's.

Abstract
AIM Pulmonary hypertension (PH) and chronic kidney disease (CKD) are interdependent for their development and exacerbation. We evaluated the effect of PH on CKD progression in patients with connective tissue disease (CTD)-associated PH. METHODS We reviewed consecutive patients with CTD who were diagnosed with PH with right heart catheter (RHC) examinations in our hospital. Patients were divided into 2 groups according to the use of vasodilators: monotherapy or combination therapy. We further divided the patients with combination therapy into early and non-early combination groups. Early combination was defined as the addition of the second vasodilator within 1 month after starting the first drug. The clinical course of hemodynamics and CKD progression were compared. RESULTS Thirty-eight patients were included in the analysis: 10 were treated with monotherapy and 28 with combination therapy (14 with early and 14 with non-early). At baseline, patients who received combination therapy had a significantly higher mean pulmonary arterial pressure with RHC and a higher right ventricular systolic pressure (RVSP) with echocardiography (P = .04) and showed a greater improvement in RVSP after treatment than those who underwent monotherapy. The incidence of CKD progression was significantly lower in patients who received combination therapy than in those who received monotherapy (P = .05). Among patients who received combination therapy, the early combination group had a lower incidence of CKD progression than the non-early combination group (P = .03). CONCLUSIONS Early combination therapy is associated with a lower incidence of CKD progression in patients with CTD-associated PH.

Abstract
OBJECTIVE To investigate the epidemiology and characteristics of systemic sclerosis (SSc) overlap syndrome (SSc-OS). METHODS This study included patients enrolled in the Siriraj Systemic Sclerosis Cohort registry during November 2013 to September 2019. SSc-OS was defined as SSc patients who also met criteria for rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), dermatomyositis (DM), polymyositis (PM), Sjogren, and/or antiphospholipid antibody syndrome. Baseline and 1-year characteristics were compared between SSc and SSc-OS. RESULTS 185 patients (age 50.3 ± 11.4 years, 85.4% female, disease duration 2.7 years, 75.1% diffuse cutaneous subset, 75.6% anti-Scl-70 positivity) were included. The incidence and prevalence rate of SSc-OS was 3.2/100 patient-years and 17.8%. Regarding SSc-OS, 12.4%, 2.2%, 1.1%, 1.6%, and 0.5% of patients were classified as SSc-RA, SSc-SLE, SSc-PM, SSc-RA-SLE, and SSc-SLE-PM. SSc-OS had a higher prevalence of limited cutaneous subset (lcSSc), usual interstitial pneumonia, finger contractures, ESR >20 mm/hr., globulin >3.5 g/dL, rheumatoid factor, anti-citrullinated peptide antibody, and antiphospholipid antibodies. LcSSc subset (OR: 11.3, 95%CI: 2.0-62.6) and globulin >3.5 g/dL (OR: 6.2, 95%CI: 1.6-23.6) were associated with SSc-OS. CONCLUSION SSc-OS is associated with the lcSSc subset. RA is the most common overlap syndrome. LcSSc patients with globulin >3.5 g/dL are associated with SSc-OS.

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
Purpose Systemic sclerosis (SSc) is characterized by multi-system inflammation and fibrosis. Ophthalmologists must be aware of the uncommon ocular features of SSc to secure the diagnosis. Observations Here we report the rare occurrence of bilateral cotton wool spots in an 86-year-old woman with SSc/lupus overlap syndrome presenting with a history of chronic obstructive pulmonary disease, gastroesophageal reflux disease, polymyalgia rheumatica, scalp tenderness, and right jaw pain on chewing. Fundoscopy showed diffuse bilateral cotton wool spots that prompted the diagnosis of SSc/lupus overlap syndrome. Conclusions The confluence of patient symptoms was disguised as separate diseases, but the funduscopic finding of cotton wool spots in a patient without known risk factors prompted further investigation and the correct diagnosis. She was started on immunosuppressant therapy but unfortunately died four months later after developing right heart failure. Importance The differential diagnosis for bilateral cotton wool spots should include autoimmune processes such as SSc and systemic lupus erythematosus and may represent an early sign that can help direct treatment.

Abstract
RATIONALE Systemic sclerosis (SSc) is a serious multisystem connective tissue disease. When SSc is accompanied by systemic lupus erythematosus (SLE), called SSc-SLE overlap syndrome. SSc associated thrombotic microangiopathy (SSc-TMA) can lead to scleroderma renal crisis, it mainly manifests hypertension or even malignant hypertension, acute kidney injury, and higher mortality. The case of SSc-SLE overlap syndrome combined with SSc-TMA has rarely been reported. PATIENT CONCERNS We report the case of an elderly male with SSc-SLE overlap syndrome combined with scleroderma renal crisis and SSc-TMA. DIAGNOSES The patient has typical of SSc on the face and hands, combined with pulmonary artery hypertension, interstitial lung disease, heart failure and malignant hypertension, as well as SLE, lupus nephritis class V, and TMA, which were definitively diagnosed by clinical laboratory examination and renal histopathology. INTERVENTIONS The patient was treated with prednisone, cyclophosphamid, renin-angiotensin system inhibitors, diuretics, and acetylcysteine. OUTCOMES The patient died suddenly of heart failure on the 35th day after discharge. LESSONS The occurrence of TMA leads to the deterioration of the prognosis of SSC-SLE overlap syndrome. The diagnosis of SSC-TMA in SSc-SLE overlap syndrome depends on clinical laboratory examination and renal histopathology.

Abstract
INTRODUCTION The safety and efficacy of pembrolizumab administration in patients with urothelial carcinoma and underlying autoimmune disease (including overlap syndrome) is unknown. CASE PRESENTATION We present the case of a 67-year-old woman with cT3N2M0 metastatic renal pelvic cancer who had been treated with prednisolone for overlap syndrome involving systemic sclerosis and systemic lupus erythematosus for 20 years. She had a remarkable response to pembrolizumab as a third-line systemic therapy, wherein the tumor reduced in size and all regional lymph node and pulmonary metastases disappeared. She did not develop any immune-related adverse events or autoimmune disease flare-ups during the treatment. CONCLUSION This case report suggests that pembrolizumab could be beneficial to patients with urothelial carcinoma and underlying well-controlled overlap syndrome.

Abstract
Systemic sclerosis (SSc) is a heterogeneous disease with variability in autoantibody profiles, skin and internal organ involvement, disease trajectory, and survival. The ability to identify more homogeneous subsets of SSc patients has informed patient care and been an essential aspect of SSc research. In this article, the historic evolution of subsetting systems in SSc are described including clinically based SSc subsetting systems, their utility, strengths, and limitations. There is a shifting paradigm of SSc subsets, including biologic classification of SSc subsets and fully data-driven approaches to SSc subset classification, taking into consideration the needs of the SSc global community in the modern era and the ability to prognosticate patients with SSc.

Abstract
INTRODUCTION Real-world use of immunomodulating therapy (IMT) in patients with systemic sclerosis (SSc) was investigated for the first time in a descriptive, retrospective cohort analysis of claims made in a healthcare insurance database to characterize treatment patterns and their alignment with SSc disease manifestations. METHODS Treatment patterns and disease manifestations, symptoms, complications, and comorbidities were assessed in patients with SSc enrolled in a US healthcare claims database who received treatment between January 2006 and December 2013 and for whom data were available 6 months before and 12 months after SSc diagnosis. RESULTS Among 7812 eligible patients, 6852 received treatments of interest for SSc and 2404 (30.8%) received IMT during the first year after SSc diagnosis. In the first year after diagnosis, the most common claims were for antibiotics (61.7%), opioids (50.6%), glucocorticoids (46.5%), and proton pump inhibitors (35.4%); the most common organs involved with complications among patients with SSc were lung (30.5%), heart (17.4%), and gastrointestinal tract (22.4%); the most common signs or symptoms were musculoskeletal (16.1%) and fatigue (10.5%); 1035 patients (15.1%) had infections and 14 (0.2%) had malignancies. Among patients who received IMT, 43.8% received at least hydroxychloroquine and 21.1% received at least methotrexate; 460 patients switched to a second IMT, 23.0% to at least methotrexate and 22.8% to at least mycophenolate mofetil. The most common comorbidities reported with first IMT were in lung (11.8%), overlap syndrome (8.4%), heart (5.3%), and gastrointestinal (6.8%) categories. CONCLUSION One-third of patients with SSc in the healthcare claims population received IMTs during the first year after diagnosis. However, patients who received IMTs had disease manifestations similar to those of the overall SSc healthcare claims population.

Abstract
Anticardiolipin antibody (ACA) is a kind of autoantibody and is one of the antiphospholipid antibodies (aPLs). Phospholipids with a negative charge on platelets and endothelial cell membranes are ACA target antigens. ACA is common in systemic lupus erythematosus and other autoimmune diseases and is closely associated with thrombosis, thrombocytopenia, and spontaneous abortion. In 1983, Harris established a method for detecting ACA, and research on the antibody has gained worldwide attention and has developed rapidly. For this review, we browsed articles that cover most of the ACA-related studies in the last 25 years and extracted influential ideas and conclusions in this field.

Abstract
Systemic sclerosis (SSc) may overlap frequently with other rheumatic diseases, including systemic lupus erythematosus (SLE), which can require high-dose steroids depending on the clinical presentation. We present a case involving this overlap in which the patient concomitantly developed lupus nephritis and Coombs (+) hemolytic anemia, which was confused with scleroderma renal crisis. In this condition, assessing for lupus nephritis with timely renal biopsy and lupus serology can aid in guiding the appropriate treatment. We discuss the clinical features and challenging management of this case with a review of the English-language literature for SSc and SLE overlap with glomerulonephritis.

Abstract
Genome-wide association studies of systemic lupus erythematosus (SLE) in Chinese and Korean populations demonstrated strong association of single nucleotide polymorphisms (SNPs) located in the GTF2I-NCF1 region, rs73366469 (GTF2I), rs117026326 (GTF2I), rs80346167(GTF2IRD1) and rs201802880 (NCF1). This region has also been associated with susceptibility to Sjögren syndrome and rheumatoid arthritis; however, association studies with systemic sclerosis (SSc) and ANCA-associated vasculitis (AAV) have not been reported. Here we made an attempt to confirm their associations with SLE in the Japanese population, to find the primarily associated SNP, and to investigate whether these SNPs are also associated with susceptibility to SSc and AAV. By genotyping these four SNPs on 842 SLE, 467 SSc, 477 AAV patients and 934 healthy controls, striking association was confirmed in Japanese SLE. In addition, these SNPs were significantly associated with susceptibility to SSc, but not with AAV. Conditional logistic regression analysis revealed that the association of NCF1 rs201802880, a missense SNP encoding p.Arg90His, can account for the association of other SNPs by linkage disequilibrium. These results suggested that GTF2I-NCF1 region is associated with susceptibility to multiple autoimmune rheumatic diseases but not with AAV, and the primarily associated variant may be the missense SNP in NCF1.

Abstract
Background The information guiding the treatment decision(s) for renal diseases in systemic sclerosis (SSc) is the renal pathological finding. This study aimed to evaluate the renal pathological diagnosis and its clinical feature among SSc. Method A historical cohort study was performed on adult Thai SSc patients who underwent renal biopsy during January 2005-December 2016. The renal pathologic findings and patient clinical characteristics were reviewed. Chi-square or Fisher's exact test was applied to analyze the association between clinical manifestation and renal pathology. Results Of the 26 SSc patients identified (77% female), 46% had the diffuse cutaneous SSc subtype. The mean age at the time of biopsy was 53.2±14.4 years and median duration of disease was 2.4 years (IQR 0.5-7.0). Rapidly progressive glomerulonephritis (RPGN) was the most common renal manifestation (53.9%) followed by nephrotic syndrome (19.2%) and nephritis (11.5%). The pathological diagnosis included lupus nephritis (LN) class IV (26.9%), LN class V (19.2%), scleroderma renal crisis (SRC; 19.3%), progressive renal disease in scleroderma (7.7%), and IgA nephropathy (7.7%). The nephrotic syndrome was the most common renal feature among LN class V patients, whereas RPGN was the commonest renal presentation among LN class IV and SRC patients (p=0.001). Dialysis treatment at the time of kidney biopsy was significantly higher in SRC patients than in the other groups (p<0.001). The SRC tended to have more frequent cardiac involvement, pulmonary fibrosis, and shorter disease duration than the other groups. Conclusion This is the first report of renal pathologic findings in Thai SSc patients. RPGN is the commonest renal manifestation among SSc who underwent kidney biopsy; for whom LN was the most common pathological finding. Nephrotic syndrome is a clinical feature of glomerular diseases other than renal involvement in SSc.

Abstract
We report the case of a 40-year-old patient with systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) overlap syndrome with pulmonary arterial hypertension (overlap-PAH) that was successfully treated with a combination of immunosuppressive therapy and the soluble guanylate cyclase stimulator riociguat. She was diagnosed with mixed connective tissue disease (MCTD) two years prior to admission. She was admitted to our hospital with dyspnea on exertion and progressive skin sclerosis. She fulfilled both SLE and SSc classification criteria and was re-diagnosed with overlap syndrome. The tricuspid valve pressure gradient (TRPG) on echocardiography was 64 mmHg at admission. On right heart catheterization, mean pulmonary arterial pressure (mPAP) was 43 mmHg and pulmonary capillary wedge pressure was 15 mmHg. We diagnosed her with SSc-SLE overlap-PAH and started treatment with corticosteroids and intravenous cyclophosphamide. We also started treatment with riociguat because we speculated she had a component of SSc-PAH and that immunosuppressive therapy alone may be insufficient. We chose riociguat because of its favorable treatment effect on SSc-PAH. Two months after treatment, her TRPG improved to 33 mmHg and the skin sclerosis improved dramatically, suggesting the efficacy of multi-drug treatment and the importance of early intervention.
