Tattooing is a procedure where ink is applied to an area of the skin, mostly intraepidermally (1). This procedure is carried out mainly for aesthetic purposes. Lately, it has been used as a corrective medical procedure following amputation of mammilla. The procedure is aggressive (2), and the fact that skin is punctured many times with the same needle which cannot be fully sterilized may cause infection of the treated area with bacterial, fungal, or viral agents that may lead to health consequences manifesting in the form of verrucae vulgaris, molluscum contagiosum, and herpes simplex...

Clindamycin is a lincomycin-derived antibiotic useful for the treatment of anaerobic and Gram-positive aerobic bacterial infections. Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier...

OBJECTIVE: Type I interferon (IFN-I) is strongly implicated in the pathogenesis of Systemic Lupus Erythematosus (SLE) as well as rare monogenic 'interferonopathies' such as Aicardi-Goutieres Syndrome (AGS) caused by mutations in the DNA exonuclease, TREX1. The DNA-activated IFN-I pathway, cyclic GMP-AMP (cGAMP) synthase (cGAS), is linked to subsets of AGS and lupus. We identified inhibitors of DNA-cGAS interaction and tested lead candidate, X6, in a mouse model of AGS. METHODS: Trex1-/- mice were treated orally from birth with either X6 or HCQ for 8 weeks...

We greatly appreciate Drs. Aditya K Panda and Bidyut K Das for their interests to our work reporting the beneficial effects of the deficiency of Lgals9 in pristine-induced lupus model of BALB/c mice(1). They have focused on the discrepancy of results between ours and recently published publication, repoting the protective effects of the administration of recombinant galectin-9 into BXSB/MpJ and NZB/W F1 mice(2). Since we identified galectin-9 and have been demonstrating the therapeutic efficacy of recombinant galectin-9 in nephrotoxic serum nephritis in Wistar Kyoto rats, diabetic nephropathy in db/db mice, and type 1 diabetes in NOD mice, we initially hypothesized that the deficiency of Lgals9 might cause the exacerbation of lupus or lupus nephritis in pristine-induced lupus model in BALB/c mice and MRL/Mpj-Faslpr /J mice...

Lupus nephritis is an immune-complexes mediated glomerulonephritis. Vascular lesions and endothelial cell injuries are common in lupus nephritis and important for renal damage. However, the precise mechanisms by which immune complexes lead to endothelial cell injuries are still unclear. Autophagy is a conserved metabolic process and shows protective roles in many cell types and diseases. In present study, we investigated whether immune complexes could affect autophagy and participate in endothelial dysfunctions...

BACKGROUND: Connective tissue autoimmune diseases (CTADs) constitute a group of conditions, including rheumatoid arthritis; systemic lupus erythematosus; mixed connective tissue disease; calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome; scleroderma; dermatomyositis; and Sjögren syndrome. There are few studies on the alterations in filiform papillae in CTAD. Thus, the objective of this work was to determine whether there are changes in the macroscopic and dermoscopic patterns of filiform papillae...

Increased IFN-γ levels have been associated with systemic lupus erythematosus (SLE). However, the relationships among IFN-γ, type I interferons (IFNs) and clinical features have not been extensively studied. Peripheral blood samples from 44 SLE patients and 36 healthy donors (HDs) were collected. Quantitative real-time PCR was used to assess the mRNA expression of IFNG, type II IFN-inducible genes (IRF1, GBP1, CXCL9, CXCL10, and SERPING1, which are used for the type II IFN score), type I IFN-inducible genes (IRF7, MX1, ISG15, and ISG20, which are used for the type I IFN score), TBX21, and EOMES in peripheral blood mononuclear cells...

Systemic lupus erythematosus is the diffuse autoimmune connective tissue disease that most frequently involves pulmonary involvement, affecting 20% of 90% of the patients. The percentage varies depending on the defining criteria (symptoms, pulmonary tests or histopathological studies). At least once during the disease course, 50% of those affected have pleural and/or pulmonary manifestations, which are associated with higher morbidity and mortality. Pulmonary involvement has no correlation with lupus activity biomarkers, and it is necessary to rule out infectious processes in the initial approach...

The excessive production of type I IFNs is a hallmark and a main pathogenic mechanism of many autoimmune diseases, including systemic lupus erythematosus (SLE). In these pathologies, the sustained secretion of type I IFNs is dependent on the improper activation of plasmacytoid DCs (pDCs) by self-nucleic acids. However, the nature and origin of pDC-activating self-nucleic acids is still incompletely characterized. Here, we report that exosomes isolated from the plasma of SLE patients can activate the secretion of IFN-α by human blood pDCs in vitro...

Mesenchymal stem cells (MSCs) have been intensively studied and applied in regenerative medicine and tissue engineering. Recently, their immune modulation functions make them as attractive potential approaches for autoimmune disease treatment. Systemic lupus erythematosus (SLE) is one type of chronic autoimmune diseases with multi-organ damaged by the immune system. Although current available treatments are effective for some patients, others are refractory for these therapies. The immuno-modulatory and regenerative characteristics of MSCs make them as one promising candidate for treating SLE...

Objectives: Activation of endosomal toll-like receptor (TLR)7 or TLR9 has been proposed as a critical step for the initiation and development of SLE. Traditional spontaneous lupus models normally introduce multiple risk alleles, thereby adding additional confounding factors. In the induced lupus models, the role of TLR9 remains unclear. In the present study, we explored the role of an imbalance between TLR7 and TLR9 pathways in the pathogenesis of lupus and its associated vasculopathy using the imiquimod model in TLR9 KO/B6 background...

Systemic lupus erythematosus (SLE) is a common heterogeneous autoimmune disease that is caused by the involvement both of genetic and environmental factors. There is evidence that autophagy is involved in several aspects of SLE pathogenesis. In particular, polymorphisms in the ATG5 gene have been observed to be associated with disease susceptibility. Our aim was to verify if ATG5 polymorphisms are involved in the susceptibility to disease and its clinical phenotypes in an Italian cohort of SLE patients. This study involved 315 SLE patients and 265 healthy controls...

OBJECTIVE: Until now, concomitant neurological manifestations and positive antiphospholipid antibodies (APA(s)) have been investigated in different manners. The most important conflicts in this field are whether those manifestations are directly related to APA(s) or not and treatment strategies. METHOD: In this study, adopting a different manner, we selected patients with a recently defined neurological problem (according to study protocol) and positive APA without any other risk factor, to compare types, amounts, and titer of APAs...

Coronary flow reserve (CFR), a measure of both obstructive coronary artery disease and microvascular dysfunction, has been evaluated in systemic rheumatic diseases (RDs), but a comprehensive critical appraisal of the available evidence is lacking. The objective of this study is to conduct a systematic review and meta-analysis of studies with small sample size investigating the associations between the presence of RDs and CFR to increase statistical power and accuracy. PubMed, Web of Science, Scopus, and Google Scholar, from inception to March 2018, were searched for studies reporting on CFR in RDs in comparison to healthy subjects...

Interleukin 35 (IL-35) is the recently identified member of the IL-12 family of cytokines and provides the possibility to be a target for new therapies for autoimmune, inflammatory diseases. It is composed of an α chain (p35) and a β chain (EBI3). IL-35 mediates signaling by binding to its receptors, activates subsequent signaling pathways, and therefore, regulates the differentiation, function of T, B cells, macrophages, dendritic cells. Recent findings have shown abnormal expression of IL-35 in inflammatory autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis, type 1 diabetes, psoriasis, multiple sclerosis, autoimmune hepatitis, experimental autoimmune uveitis...

Lupus erythemathosus is a chronic, relapsing disease with acute, subacute, and chronic lesions. Effluvium telogen occurs in the setting of systemic activity of the disease, and cicatricial alopecia results from discoid lesionsin on the scalp. Other types of alopecia, like alopecia areata, may rarely be found in lupus. Frontal fibrosing alopecia is characterized by frontotemporal hairline recession and eybrow loss. Histophatologically, it cannot be differentiated from lichen planopilaris.It is controversial whether frontal fibrosing alopecia is a subtype of lichen planopilaris...
