Catastrophic antiphospholipid syndrome (CAPS) is a rare and fatal condition that is characterized by diffuse venous and/or arterial thromboembolism within a short period of time and histopathological confirmation of small-vessel occlusion in at least one organ or tissue in the presence of positive antiphospholipid antibodies. Here we report the case of a 19-year-old woman with CAPS. During the first week of her hospitalization, she was diagnosed with CAPS on the basis of skin necrosis, pulmonary artery thrombosis, cerebral venous sinus thrombosis, and positive lupus anticoagulant...

Parvovirus B19 infections in adults are usually associated with nonspecific and mild symptoms. However, cases presenting with a lupus-like syndrome have been described, leading to the hypothesis that parvovirus infection can induce connective tissue disease. Various histopathologic features of cutaneous manifestations of parvovirus have been reported, including features which overlap with those of connective tissue disease. Herein, we discuss an unusual case of Parvovirus  B19 infection in a middle-aged woman...

Autoimmune diseases (ADs) are a heterogeneous groups of diseases that occur as a results of loss of tolerance to self antigens. While the etiopathogeneis remain obscure, different environmental factors were suggested to have a role in the development of autoimmunity, including infections, low vitamin D levels, UV radiation, and melatonin. Interestingly, such factors possess seasonal variation patterns that could influence disease development, severity and progression. Vitamin D levels which reach a nadir during late winter and early spring is correlated with increased disease activity, clinical severity as well as relapse rates in several disease entities including multiple sclerosis (MS), non-cutaneous flares of systemic lupus erythematosus (SLE), psoriasis, and rheumatoid arthritis (RA)...

BACKGROUND: Chronic cutaneous lupus erythematosus (CCLE) often affects the scalp resulting in scarring alopecia. While histopathologic findings of CCLE have been well described, there is little written on the morphologic changes to the hair follicles in this condition. OBJECTIVE: We aim to determine the histopathologic findings of hair follicles in CCLE of the scalp. METHODS: We conducted a retrospective study of 33 transversely sectioned skin biopsy specimens of CCLE of the scalp at the Skin Pathology Laboratory at Boston University between April 2005 and March 2015...

Lupus mastitis is an uncommon manifestation of systemic lupus erythematosus (SLE) that affects the subcutaneous fat in the breast, much like lupus panniculitis, but additionally involves the mammary gland. We report on two women for whom lupus mastitis was the initial manifestation of SLE and provide a literature review of 34 additional cases reported in the Anglo-Saxon and French literature since 1971, making this the largest review to date. Lupus mastitis (LM) can manifest clinically as subcutaneous masses that may be painful, or may present cutaneous involvement such as thickening and discolouration...

Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) binds to its sole receptor fibroblast growth factor-inducible 14 (Fn14), participating in various inflammatory responses. Recently, TWEAK/Fn14 activation was found prominent in the lesions of cutaneous lupus erythematosus (CLE). This study was designed to further reveal the potential role of this pathway in Ro52-mediated photosensitization. TWEAK, Fn14, and Ro52 were determined in the skin lesions of patients with CLE. Murine keratinocytes received ultraviolet B (UVB) irradiation or plus TWEAK stimulation and underwent detection for Ro52 and proinflammatory cytokines...

Background Venous thromboembolism (VTE) is a major public health concern. Lupus erythematosus (LE) is a chronic autoimmune disease ranging from localized cutaneous disease (CLE) to systemic involvement (SLE). Patients with SLE have an increased risk of venous thromboembolism (VTE), but little is known about the CLE-related risk of VTE. Methods To evaluate the risk of VTE in patients with SLE and CLE as compared to the general population, a retrospective cohort study was conducted. Incidence rates and hazard ratios (HRs) with 95% confidence intervals (CIs) from multivariable Cox regression models were used to evaluate and compare the risk of VTE...

BACKGROUND: The clinical outcomes following rituximab (RTX) treatment in patients with systemic lupus erythematosus (SLE) is highly variable. We aimed to identify predictive and prognostic factors associated with RTX therapy outcomes in patients with SLE. METHODS: Studies in adults and paediatric patients with SLE were included. We included randomized clinical trials (RCTs) for predictors of differential treatment effect and cohort studies for potential prognostic factors in patients treated with RTX (global clinical, cutaneous and renal either response or relapse, and side effects)...

Neonatal lupus erythematosus is an autoimmune disease resulting from the trans-placental passage of maternal anti-SSA/Ro, anti-SSB/La, and less frequently anti-RNP antibodies to the foetus. At the time of diagnosis 50% of mothers are asymptomatic. Neonatal manifestations of this multisystem disease may include congenital heart block, cutaneous lesions and haematological abnormalities. We present the case of congenital neonatal lupus erythematosus in non-identical twins, showing variability in clinical manifestation of this disease,despite receiving the same level of antibodies from the mother...

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids. Other systemic therapies include systemic steroid, azathioprine, dapsone, and immunosuppressive agents. Topical tacrolimus and pimecrolimus have also been evaluated. Recent studies reported that several treatments, including pulsed dye laser, CO2 laser, intense pulsed light (IPL), and 1,064-nm long-pulse neodymium-doped yttrium aluminum (Nd:YAG) have been used for the cosmetic treatment of DLE...

Macrocheilia is a challenging problem with a variety of underlying causes that are both local and systemic, and granulomatous causes underlie the majority of cases. In this study, we report on a 31-year old man who presented with a chronic lower lip enlargement and a nodular submental erythematous lesion. He was otherwise clinically healthy. Laboratory test results were within the normal limit except for a positive anti-double stranded DNA test result. A diagnosis of cutaneous lupus erythematosus was made on the basis of histopathology and direct immunofluorescence...

Toll-like receptor 4 (TLR-4), a bacterial lipopolysaccharide sensor, is an innate immunity essential modulator. It is expressed on both immune and non-immune cells and may contribute to the cutaneous and renal manifestations during lupus erythematosus (LE). Our purpose is to evaluate TLR-4 expression and analyzing its role in lupus nephritis (LN) and chronic cutaneous lupus erythematosus (CLE) pathogenesis. TLR-4 immunohistochemical staining was performed on 30 LN renal biopsies compared with 11 healthy renal tissues and 30 skin biopsies from CLE patients compared with 15 normal individuals...

INTRODUCTION: C1q play an important role in clearance of immune complexes and apoptotic cell debris. Impaired clearance leads to exposure of C1 native antigen and development of anti-C1q antibody formation. Anti-C1q antibody is well studied in Systemic Lupus Erythematosus (SLE). Significance of anti-C1q Ab in Indian SLE patients and their clinical manifestations is not clear. AIM: The aim of this study was to investigate associations between anti-C1q antibody and clinical as well as serological markers of SLE...

Mycobacterium abscessus infection tends to occur in patients with an advanced immunocompromised status. We encountered a case of intractable cutaneous M. abscessus infection that developed in a patient with systemic lupus erythematosus (SLE) during maintenance therapy. A 28-year-old woman developed a fever and redness of the skin on her buttocks. General antibacterial therapy was ineffective, and acid-fast bacteria were detected in the biopsy that was conducted to differentiate the dermal symptoms of SLE. The clinical findings eventually improved; however, the symptoms recurred multiple times during treatment...
