OBJECTIVE: Systemic lupus erythematosus (SLE) may affect a number of systems, with the hematological system being one of the most common. Our aim is to determine the existence of cytopenia at diagnosis or during follow-up of our SLE patients as well as the associated factors. MATERIAL AND METHODS: A cohort of SLE patients that had been followed-up in the Department of Rheumotology from 1998 to 2015 was retrospectively assessed. Clinical and laboratory findings about the patients were recorded...

Background Anti-double stranded DNA antibodies are a very heterogeneous group of antibodies, quite specific for systemic lupus erythematosus. Newer technologies, such as addressable laser bead immunoassays (ALBIA), show great potential as a diagnostic application. The production of anti-double stranded DNA antibodies is often encountered in inflammatory arthritis; however, literature reports that the actual onset of drug induced lupus in patients treated with biological drugs is a rare event. False positive results for anti-double stranded DNA and anti-nucleosome antibodies detected in patients with inflammatory arthritis treated with different biologics prompted the investigation of full autoantibody profiles to evaluate each biomarker's diagnostic performance in systemic lupus erythematosus...

In analogy to apoptosis of nucleated cells, erythrocytes may enter eryptosis characterized by cell shrinkage and cell membrane scrambling. Eryptotic erythrocytes are rapidly cleared from circulating blood and may adhere to the vascular wall. Stimulation of eryptosis thus impairs microcirculation and leads to anemia as soon as the loss of erythrocytes cannot be fully compensated by enhanced erythropoiesis. Signaling stimulating eryptosis includes increase of cytosolic Ca(2+) -activity, ceramide, caspases, calpain, p38-kinase, protein-kinase C, Janus-activated kinase 3, casein-kinase 1α, and cyclin-dependent kinase 4...

BACKGROUND: Vitiligo is a multifactorial disease that is characterized by circumscribed depigmented macules and patches. Autoimmune reactions may play an important role in the pathogenesis of the disease. Mycophenolate mofetil is a drug that inhibits DNA synthesis in lymphocytes and has been used in autoimmune diseases such as immunobullous skin diseases, lupus erythematosus, and autoimmune hepatitis. OBJECTIVES: The objective of this study was to show the efficacy of topical mycophenolate mofetil in the treatment of vitiligo...

Antimalarials have demonstrated beneficial effects in Systemic Lupus Erithematosus and Rheumatoid Arthritis. However, the mechanisms and the molecular players targeted by these drugs remain obscure. Although hydroxychloroquine (HCQ) is a known ion channel inhibitor, this property has not been linked to its anti-inflammatory effects. We aimed to study whether HCQ inhibits pro-inflammatory ion channels. Electrophysiology experiments demonstrated that HCQ inhibited Ca(++)-activated K(+) conductance in THP-1 macrophages in a dose-dependent manner...

BACKGROUND: Fabry Disease (FD) is a genetic disorder caused by alpha-galactosidase A deficiency. Certain drugs, such as hydroxychloroquine, can produce renal deposits that mimic morphological findings seen in FD, characterizing a type of drug-induced renal phospholipidosis. CASE PRESENTATION: Case 1: A 28-year-old female patient with systemic lupus erythematosus who had been using hydroxychloroquine for 14 months presented subnephrotic proteinuria. Renal biopsy showed deposits compatible with FD...

Erythroderma is characterized by diffuse erythema and scaling of the skin involving more than 90% of the total body skin surface area. Drug-induced erythroderma has rarely been reported with hydroxychloroquine. We report a case of a 50-year-old female patient, with systemic lupus erythematosus, who developed itchy lesions all over the body 1 month after starting treatment with hydroxychloroquine. Drug-induced erythroderma was suspected. Hydroxychloroquine was withdrawn and the patient was treated with emollients, mid-potency corticosteroids, and oral antihistamines...

The metabolism of tryptophan through kynurenine and serotonin pathways is linked to depression. Here, effects of different drugs with antidepressant properties (vortioxetine, fluoxetine, and ketamine) on various tryptophan metabolites in different brain regions and plasma were examined using tandem mass spectrometry (LC-MS/MS), in Flinders Sensitive Line rats, a genetic rat model of depression, and its controls: Flinders Sensitive Line and Sprague-Dawley rats. Protein levels of kynurenine pathway enzymes were measured in the brains and livers of these rat strains...

Animal models are a key element in disease research and treatment. In the field of neuropsychiatric lupus research, inbred, transgenic and disease-induced mice provide an opportunity to study the pathogenic routes of this multifactorial illness. In addition to achieving a better understanding of the immune mechanisms underlying the disease onset, supplementary metabolic and endocrine influences have been discovered and investigated. The ever-expanding knowledge about the pathologic events that occur at disease inception enables us to explore new drugs and therapeutic approaches further and to test them using the same animal models...

Dendritic cells (DCs) play an important role in the development and maintenance of immune tolerance. Activation of TLR7, which is expressed in DCs, is thought to contribute to the complex pathophysiology of systemic lupus erythematosus (SLE). In this study, we analyzed the in vitro and in vivo function of a novel small-molecule compound, FC-99, which was previously reported to have immunomodulatory functions. We found that FC-99 inhibited the expression of CD40 and inflammatory mediators (IL-6, IL-12, and CXCL-10), as well as R848-induced phosphorylation of IκB-α...

Introduction Hydroxychloroquine is an antimalarial agent widely prescribed in internal medicine, rheumatology and dermatology. Its use can be complicated by various side effects including skin pigmentation. Objectives The aim of the study is to review epidemiological, clinical features and risk factors of hydroxychloroquine-induced pigmentation. Materials and methods We performed a cross-sectional study conducted over a period of 5 months. During this period, patients who had been treated with hydroxychloroquine for over 6 months, in the internal medicine department, underwent a complete dermatological examination...

Subacute cutaneous lupus erythematosus (SCLE) is a well-defined subtype of lupus erythematosus, characterised by photosensitivity, annular and/or psoriasiform lesions, variable systemic involvement and presence of circulating SSA/anti-Ro antibodies. SCLE may be idiopathic or drug-induced. Both the idiopathic and drug-induced forms of SCLE are analogous in their clinical, serological and histological features. Drug-induced SCLE has been reported with various oral agents, but to our knowledge this is the first reported case due to a topical medication...

BACKGROUND: It has been over three decades sincethe first report of drug-induced subacute cutaneouslupus erythematosus (DI-SCLE) was described. Withan increasing variety of implicated drugs and thepotential for publication bias, we must consider: 1) hasthere been a change in drugs most often reported inDI-SCLE over time, and, 2) if so, of which drugs shouldclinicians be most suspicious in the setting of possibleDI-SCLE? OBJECTIVE: To determine which drug(s) present thehighest risk for inducing DI-SCLE...

INTRODUCTION: This article introduces a new case of Rowell's syndrome, a controversial entity defined by the association of lupus erythematosus and erythema multiforme. OBSERVATION: A 43-year-old woman was diagnosed with lupus erythematosus induced by esomeprazole. Because her eruption did not improve after withdrawal of the drug, hydroxychloroquine was administered. Two weeks later, the patient described new annular lesions on her chest and arms, both erosive and crusted, and some had a target-like appearance...

We report a 51-year-old female with a 3-year history of recalcitrant annular elastolytic giant cell granuloma (AEGCG) who was effectively treated with the anti-tumor necrosis factor (TNF)-alpha antibody, adalimumab. Her disease was refractory to topical glucocorticoids, intralesional glucocorticoids, narrow-band ultraviolet light (UV)-B phototherapy and cyclosporine. During her treatment with adalimumab she developed a positive anti-nuclear-antibody and double-stranded-DNA antibody and her treatment was terminated...

Subacute cutaneous lupus erythematosus (SCLE) is characterized by particular cutaneous manifestations such as non-scaring plaques mainly in sunlight exposed parts of the body along with specific serum autoantibodies (i.e. antinuclear antibodies (ANA), Ro/SSa, La/SSb). It is considered either idiopathic or drug induced. The role of chemotherapeutic agents in causing SCLE has been investigated with the taxanes being the most common anticancer agents. However, recent data emerging point toward antiestrogen therapies as a causative factor not only for SCLE but also for a variety of autoimmune disorders...

Facial erythema (the "red face") is a straightforward clinical finding, and it is evident even to the untrained eye; however, a red face does not represent a single cutaneous entity. It may be due to a plethora of distinct underlying conditions of varying severity, including rosacea, demodicosis, dermatomyositis, lupus erythematosus, allergic contact dermatitis, drug-induced erythema, and emotional blushing. In clinical practice, dermatologists do not encounter only one type of facial erythema but rather a number of different shades of red...

OBJECTIVE: Lupus develops when genetically predisposed people encounter certain drugs or environmental agents causing oxidative stress such as infections and sun exposure, and then typically follows a chronic relapsing course with flares triggered by the exogenous stressors. Current evidence indicates that these environmental agents can trigger lupus flares by inhibiting the replication of DNA methylation patterns during mitosis in CD4(+) T cells, altering the expression of genes suppressed by this mechanism that convert normal "helper" cells into auto reactive cells which promote lupus flares...
