RATIONALE: Lupus panniculitis (LP) is a unique variant of cutaneous lupus erythematosus. Clinical manifestations are typically mild and include erythema, nodules, and small ulcers. In certain cases, diagnosing LP may be challenging. Skin overlying the typical subcutaneous inflammation may appear normal, and bacterial superinfections of the skin sometimes mask the underlying LP. It has been suggested that a computed tomography (CT) scan may help to identify obscure LP lesions. Here, we report a case of a 54-year-old woman with an unusually severe form of LP, in which the full disease extent was only revealed by a fluorodeoxyglucose positron emission tomography (FDG-PET)/CT scan...

Drug Induced Lupus Erythematous (DILE) is a rare adverse reaction to a large variety of drugs including Isoniazid (INH), with features resembling idiopathic Systemic Lupus Erythematosus (SLE). Diagnosis require identification of a temporal relationship between drug administered and symptom. It is an idiosyncratic reaction, with no pre-existing lupus. Our case highlights a rare presentation of isoniazid induced lupus with profound pancytopenia and mucosal ulcers, thus posing a diagnostic challenge. The patient was on multidrug treatment for pulmonary and knee joint tuberculosis...

Cytomegalovirus (CMV) infection have been described as exacerbing systemic lupus erythematous (SLE). The role of CMV in starting off SLE remains object of debate. We report a severe presentation of SLE revealed by CMV infection with hemophogocytic syndrome. A 22 old women without a history of systemic disease developed a cutaneous eruption with fever and myalgia persistant for 2 weeks. Laboratory studies revealed a CMV serology supporting acute CMV infection, with positive antinuclear antidody, anti ds DNA, elevated liver functions tests, pancytopenia...

Nitric oxide (NO) produced by endothelial cells interacts with erythrocyte through band 3 protein, being scavenged by haemoglobin. A signal transduction mechanism involving protein Gi and protein band 3 stimulates erythrocyte NO efflux when acetylcholine (ACh) binds to erythrocyte membrane acetylcholinesterase. Binding of normal plasma fibrinogen (Fib) levels, to erythrocyte membrane CD47 decreases the NO efflux. When high Fib concentration and ACh were present the efflux of NO from erythrocytes was normalized...

BACKGROUND: von Willebrand factor (VWF) is involved in platelet plug formation and protein transport. Increased VWF levels in systemic lupus erythematous (SLE) are considered risk factors for vascular events. VWF protein levels, however, do not accurately reflect its platelet-aggregating function, which has not been examined in SLE. METHODS: Cross-sectional study with clinical and laboratory data obtained in patients with SLE (n=92) from a regional lupus registry...

Chronic cutaneous lupus erythematosus in a linear configuration is rare, particularly in children, demonstrating similar incidence in both genders, no photo-sensitivity and lower probability of progression to systemic disease. We describe the case of a 9-year-old girl who presented erythematous papules with central atrophy on the upper and lower right limbs, asymptomatic and following the lines of Blaschko, since age four. Histological examination showed atrophy of the epidermis with aggression from epidermal-dermal interface and periadnexal and perivascular lymphocytic inflammatory infiltrate...

The antiphospholipid syndrome is a common autoimmune disease caused by pathogenic antiphospholipid antibodies, leading to recurrent thrombosis and/or obstetrical complications. Importantly for nephrologists, antiphospholipid antibodies are associated with various renal manifestations including large renal vessel thrombosis, renal artery stenosis, and a constellation of intrarenal lesions that has been termed antiphospholipid nephropathy. This last condition associates various degrees of acute thrombotic microangiopathy, proliferative and fibrotic lesions of the intrarenal vessels, and ischemic modifications of the renal parenchyma...

Systemic lupus erythematous (SLE) is a chronic heterogeneous multisystem autoimmune disease characterized by loss of tolerance to self-antigens and production of numerous autoantibodies. Current therapeutic approaches used to treat inflammatory autoimmune diseases are associated with debilitating side effects. In spite of significant advances in therapeutic options and increased understanding of the pathogenesis, novel therapeutic approaches are needed for treatment of SLE. Nanoparticle-based delivery systems that selectively deliver drugs to inflamed tissue or specific cell have the potential to improve drug delivery...

Autoimmune disease encompasses an array of conditions with a variety of presentations and the involvement of multiple organs. Though the etiologies of many autoimmune conditions are unclear, uncontrolled inflammatory immune response is believed to be a major cause of disease development and progression. Progranulin (PGRN), an anti-inflammatory molecule with therapeutic effect in inflammatory arthritis, was identified as an endogenous antagonist of TNFα by competitively binding to TNFR. PGRN exerts its anti-inflammatory activity through multiple pathways, including induction of Treg differentiation and IL-10 expression and inhibition of chemokine release from macrophages...

BACKGROUND: Lupus myocarditis is likely more common than recognized clinically due to non-specific symptoms and lack of reliable non-invasive diagnostic tests. We investigated the role of native T1 and T2 in recognition of active myocardial inflammatory involvement in patients with systemic lupus erythematous (SLE). METHODS: 76 patients with clinically suspected lupus myocarditis (14 males, age: 44±16years) underwent quantitative tissue characterization with native T1 and T2 mapping...

A 22-year-old Caucasian man presented to hospital with pleuritic chest pain. He had had a history of a sun-sensitive rash a year prior. Workup revealed normal cardiac enzymes and chest X-ray. However, electrocardiogram revealed ST elevation and PR depression, and echocardiogram revealed a slight pericardial effusion without other findings. A diagnosis of pericarditis was made. Subsequently, he was found to be positive for antinuclear antibodies (ANAs), as well as antibodies to SSA, SSB and double-stranded DNA; C3 was low, and C4 was undetectable...

Systemic lupus erythematous (SLE) is a chronic autoimmune disease associated with genetic and environmental risk factors. However, the extent to which genetic risk is causally associated with disease activity is unknown. We utilized longitudinal-targeted maximum likelihood estimation to estimate the causal association between a genetic risk score (GRS) comprising 41 established SLE variants and clinically important disease activity as measured by the validated Systemic Lupus Activity Questionnaire (SLAQ) in a multiethnic cohort of 942 individuals with SLE...

AIMS: Several studies suggested that systemic lupus erythematosus (SLE) were associated with the risk of lung cancer. However, other studies did not confirm the result. Therefore, we conducted a meta-analysis to investigate this association. MATERIALS AND METHODS: A systematic literature search was conducted using the PubMed, Cochrane Library, EMBASE, Chinese National Knowledge Infrastructure, and WANFANG databases for relevant published articles. The strength of the associations between SLE and lung cancer risk was measured by odds ratio (ORs) and 95% confidence interval (CIs)...

The folic acid analogue methotrexate is used as an anti-neoplastic agent and treatment for inflammatory disorders including psoriasis, dermatomyositis, lupus erythematous, sarcoidosis, and systemic sclerosis. Despite the introduction of newer biologic agents, methotrexate remains a first-line systemic therapy for many patients with disorders of chronic inflammation. Here we briefly describe the current clinical evidence for methotrexate use in psoriatic disease, our current understanding of methotrexate's anti-inflammatory properties, and the future role of methotrexate in the treatment of immune mediated disorders...
