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 (FSL) rats, a genetic rat model of depression, and its controls: Flinders Resistant Line (FRL) and Sprague-Dawley (SD) 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...

Drug induced lupus erythematosus (DIL or DILE) is an autoimmune disorder caused by chronic use of certain drugs. We report a unique case of hydralazine induced lupus syndrome (HILS) with a negative antinuclear antibody in a female patient who was on hydralazine for a period of 1.5-2 years and developed recurrent pericardial effusion as a result of it. Initially her condition was managed with a pericardial window. The recurrence of a massive pericardial effusion necessitated a right hemipericardiectomy. After hydralazine was stopped, she never had any further episodes of pericardial effusion or tamponade...

WHAT IS KNOWN AND OBJECTIVE: Drug-induced lupus erythematosus occurs with some drugs and resolves with their withdrawal. Anti-TNF therapies have been found to be associated with a lupus-like syndrome, which is clinically distinct from classical drug-induced as well as idiopathic lupus erythematosus. CASE DESCRIPTION: We describe a case of a patient with severe psoriasis, who developed muscle pain with paraesthesia accompanied by ANA titres elevation with adalimumab treatment...

It is currently believed that autoimmune conditions are triggered and aggravated by a variety of environmental factors such as cigarette smoking, infections, ultraviolet light or chemicals, as well as certain medications and vaccines in genetically susceptible individuals. Recent scientific data have suggested a relevant role of these factors not only in systemic lupus erythematosus, but also in cutaneous lupus erythematosus (CLE). A variety of environmental factors have been proposed as initiators and exacerbators of this disease...

Skin manifestations are common in patients with inflammatory bowel diseases (IBD) and can be part of a concomitant illness with a shared genetic background, an extra-intestinal manifestation of the disease, or a drug side-effect. Areas covered: We provide a practical overview of the epidemiology, pathogenesis, diagnosis, therapeutic approach and prognosis of the most frequent disease-related and drug-induced cutaneous manifestations in IBD, illustrated by cases encountered in our clinical practice. Among the most frequently encountered IBD-related lesions are erythema nodosum, pyoderma gangrenosum and Sweet's syndrome...

Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care...

Lupus nephritis (LN) is the major clinical manifestation of systemic lupus erythematosus. LN is promoted by T helper 17 (Th17) cells, which are the major pro-inflammatory T cell subset contributing to autoimmunity regulation. Nuclear factor erythroid 2-related factor 2 (NRF2) is critical for suppressing reactive oxygen species (ROS) and relieving oxidant stress by regulating antioxidant gene expression. Previous studies have demonstrated that Nrf2 deficiency promotes drug-induced or spontaneous LN. However, whether NRF2 regulates Th17 function during LN development is still unclear...
