BACKGROUND: The antiphospholipid syndrome (APS) is defined by simultaneous presence of vascular clinical events and antiphospholipid antibodies (aPL). The aPL considered as diagnostics are lupus anticoagulant and antibodies anticardiolipin (aCL) and anti-ß2 glycoprotein-I (aB2GP1). During recent years, IgA aB2GP1 antibodies have been associated with thrombotic events both in patients positive, and mainly negative for other aPL, however its value as a pro-thrombotic risk-factor in asymptomatic patients has not been well defined...

Mesangial proliferative lupus nephritis may coexist with podocytopathy, but its clinical-morphological features, treatment response and outcomes have not been compared with mesangial proliferative lupus nephritis without podocytopathy. In this study, 125 biopsies of lupus nephritis patients showing mesangial proliferation with mesangial immune deposits were collected and divided into podocytopathy group (defined as podocyte foot process effacement (FPE) >50% with nephrotic syndrome (NS)) and mesangial group (FPE ≤50%, or FPE >50% without NS)...

Distinction of chilblain lupus erythematosus (CLE) from idiopathic perniosis (IP) could predict an underlying connective tissue disease; however, histopathologic discrimination of the two is difficult. Increased CD123 plasmacytoid dendritic cells and CD30 lymphocytes have been demonstrated in various forms of cutaneous lupus erythematosus and IP, respectively. To our knowledge, CD123 and CD30 have not been examined in CLE. Our objective was to identify helpful histopathologic and immunohistochemical features in distinguishing CLE and IP...

BACKGROUND: Best practices for managing childhood-onset membranous lupus nephritis (MLN) are not yet established. Most studies involve primarily or exclusively adult cohorts or pediatric cohorts with combinations of pure or mixed membranous and proliferative nephritis. METHODS: We performed a single-center cohort study of consecutively diagnosed children with pure MLN from 1990 and 2016. Patients received care in Houston, Texas, one of the most diverse metropolitan areas in North America...

Raccoons (Procyon lotor) are found worldwide. They are frequently seen in crowded inner cities as well as in forests or wooded areas, often living in proximity to humans and their pets. We examined sera from 100 wild raccoons in Japan for antibodies to six canine viruses with veterinary significance to assess their potential as reservoirs. We also aimed to understand the distribution of potentially infected wildlife. We found that 7% of samples were seropositive for canine distemper virus (CDV), 10% for canine parvovirus type (CPV), 2% for canine adenovirus type 1, 6% for canine adenovirus type 2, and 7% for canine coronavirus...

To guide management decisions of an index patient evidence is required from comparisons between approximate matches to the profile of the index case, where some matches contain responses to treatment and others act as controls. We describe a method for constructing clinically relevant histories/profiles using data collected but unreported from two recent phase 3 RCTs assessing belimumab in subjects with clinically active and serologically positive SLE. Outcomes were the SRI (SLE Responder Index) measured at 52 weeks...

The aim of this study is to investigate the association of estrogen receptor alpha gene (ESR1) polymorphisms, additional gene-gene, and gene-environment interaction with systemic lupus erythematosus (SLE) risk. SNPStats (available online at http://bioinfo.iconcologia.net/SNPstats ) was used to investigate the Hardy-Weinberg equilibrium (HWE) in controls and association between SNP and SLE risk. Generalized multifactor dimensionality reduction (GMDR) was used to screen the interactions among SNPs and environmental risk factors; SLE risk was significantly higher in carriers of rs2234693 C allele than those with TT (TC + CC versus TT), adjusted OR (95%CI) = 1...

BACKGROUND: Hormonal fluctuations during menopause lead to endocrine changes in women, especially in their sex steroid hormone production. Studies have documented the role of estrogen and progesterone (Pg) on autoimmune disorders such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Lichen planus (LP), an autoimmune disorder, seen frequently in perimenopausal women, may also get affected by sex steroid hormones, but no direct relationship has been established yet...

INTRODUCTION: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). Renal involvement is a major determinant of the prognosis of SLE. The histological classification of LN is a key factor in determining the renal survival of patients with LN. Prompt recognition and treatment of renal disease are important, as early response to therapy is correlated with better outcome and renal biopsy plays an important role in achieving this. OBJECTIVES: The objective of this study was to correlate the clinical and laboratory findings with histopathological classes of LN as per the 2003 International Society of Nephrology-Renal Pathology Society (ISN/RPS) classification system...

A 46-year-old woman with a 30 pack-year smoking history presented with a worsening eruption on the left cheek that failed to improve with metronidazole gel. The cutaneous eruption spread to most of her face and did not respond to a brief tapering course of prednisone. During the initial evaluation at our institution, approximately 6 weeks after the onset of the cutaneous eruption, the patient had erythematous, crusted plaques on her face and scalp (Figure 1A); they were also present on the V-area of the anterior aspect of the neck and upper region of the chest, the shoulders, and the arms, with isolated lesions on the trunk and legs...

BACKGROUND: Systemic lupus erythematosus, characterized by persistent inflammation, is a complex autoimmune disorder with no known cure. Immunosuppressants used in treatment put patients at a higher risk of infections. New knowledge of disease modulators, such as symbiotic bacteria, can enable fine-tuning of parts of the immune system, rather than suppressing it altogether. RESULTS: Dysbiosis of gut microbiota promotes autoimmune disorders that damage extraintestinal organs...

INTRODUCTION: Epidermodysplasia verruciformis (EV) is a rare inherited dermatosis characterized by increased susceptibility to human papilloma virus infection. Acquired EV occurs in patients with compromised cell-mediated immunity, such as patients with HIV and transplant recipients. Optimal management of acquired EV has not yet been established, as cases are rare and are due to a variety of underlying conditions. Additionally, no distinctions have been made between different immunosuppressive medications and their respective link to EV...

Human leukocyte antigen-G (HLA-G) presents inhibitory functions in immune cells and is located in a chromosomal region associated with systemic lupus erythematosus (SLE) susceptibility. Polymorphisms in 3' untranslated region (3'UTR) of HLA-G gene may influence protein expression. To date, no study analyzing HLA-G polymorphism and expression in childhood-onset systemic lupus erythematosus (cSLE) has been conducted. Therefore, we investigated the influence of HLA-G 3'UTR polymorphisms in 50 cSLE patients and 144 healthy controls...

Systemic lupus erythematosus (SLE) is an autoimmune disease that is frequently treated with high doses of corticosteroids and other immunosuppressive drugs. Thus patients with SLE are at increased risk for infections with several pathogens including Mycobacterium tuberculosis. There are no established guidelines available for treatment of tuberculosis in SLE patients with high disease activity due to lack of relevant studies and management based more on physician expertise. We report a case of a young SLE patient with high disease activity index (SLEDAI19) as evidenced by the presence of a vasculitic rash, non-healing ulcer on forearm and proteinuria of >1 g/d along with miliary tuberculosis...

BACKGROUND: Obesity is increasingly prevalent and related to increased risk of several autoimmune diseases, likely via generation of inflammatory adipokines. Prior studies have not evaluated obesity in relation to systemic lupus erythematosus (SLE) risk. We prospectively evaluated whether obesity was associated with increased SLE risk among women in the U.S. Nurses' Health Study cohorts. METHODS: We conducted a prospective cohort study among 238,130 women in the Nurses' Health Studies (NHS, 1976-2012; NHSII, 1989-2013)...

BACKGROUND: Sporadic inclusion body myositis (sIBM) is usually classified as an idiopathic inflammatory myopathies. Although the diagnosis of sIBM is sometimes challenging, recent studies have shown that the autoantibodies against cytosolic 5'-nucleotidase 1A (NT5C1A) are the possible diagnostic biomarker for sIBM. Few reports have shown the frequencies of anti-NT5C1A antibodies in systemic autoimmune rheumatic diseases (SARDs) using large cohorts of SARDs. METHODS: Serum samples obtained from 314 patients including dermatomyositis (DM) (n=144), systemic lupus erythematosus (SLE) (n=50), systemic sclerosis (SSc) (n=50), Sjögren's syndrome (SS) (n=50), polymyositis (PM) (n=10) and mixed connective tissue disease (n=10), and healthy controls (n=42) in addition to 10 patients with typical sIBM were analysed for the presence of autoantibodies using full-length recombinant NT5C1A ELISA...
