BACKGROUND: Genetic variation in the Laccase (multicopper oxidoreductase) domain-containing 1 (LACC1) gene has been shown to affect the risk of Crohn's disease, leprosy and, more recently, ulcerative colitis and juvenile idiopathic arthritis. LACC1 function appears to promote fatty-acid oxidation, with concomitant inflammasome activation, reactive oxygen species production, and anti-bacterial responses in macrophages. We sought to contribute to elucidating LACC1 biological function by extensive characterization of its expression in human tissues and cells, and through preliminary analyses of the regulatory mechanisms driving such expression...

Granulomatous inflammations are a particular type of chronic septic or aseptic inflammation, in which infectious or non-infectious agents are difficult to eliminate by the immune system. These are type IV hypersensitivity reactions mediated by pre-sensitized T-lymphocytes cells CD4+ and CD8+ lymphocytes. Disorders included in this category are: tuberculosis, leprosy, syphilis, sarcoidosis, type I diabetes, multiple sclerosis, Crohn's disease and rheumatoid arthritis. At cutaneous level, this pattern of granulomatous reaction is characterized by a chronic inflammation with formation of granulomas consisting of a variable number of histiocytes, multinucleated giant cells and lymphocytes...

Single-nucleotide variations in C13orf31 (LACC1) that encode p.C284R and p.I254V in a protein of unknown function (called 'FAMIN' here) are associated with increased risk for systemic juvenile idiopathic arthritis, leprosy and Crohn's disease. Here we set out to identify the biological mechanism affected by these coding variations. FAMIN formed a complex with fatty acid synthase (FASN) on peroxisomes and promoted flux through de novo lipogenesis to concomitantly drive high levels of fatty-acid oxidation (FAO) and glycolysis and, consequently, ATP regeneration...

Rheumatologic manifestations not only are encountered in leprosy but also can be the first and even the sole presenting manifestation. The hallmark of leprosy is skin and peripheral nerve affection; however, it can affect a wide range of other organs, with the joints being the commonest. We have searched PubMed with the key words leprosy, arthritis, vasculitis, rheumatic diseases, and autoantibodies in a proper combination. Relevant studies were retrieved from scanning of their abstracts. The relevant references provided in these articles were also selected and reviewed...

The function of the Laccase domain-containing 1 (LACC1) gene is unknown, but genetic variation at this locus has been reported to consistently affect the risk of Crohn's disease (CD) and leprosy. Recently, a LACC1 missense mutation was found in patients suffering from monogenic forms of CD, but also systemic juvenile idiopathic arthritis. We tested the hypothesis that LACC1 single nucleotide polymorphisms (SNPs), in addition to CD, are associated with juvenile idiopathic arthritis (JIA, non-systemic), and another major form of inflammatory bowel disease, ulcerative colitis (UC)...

Biologics are relatively new drugs developed through modern monoclonal antibody techniques and became more familiar to some disease treatments such as Rheumatoid arthritis, psoriasis, ankylosing spondylitis, ulcerative colitis, malignant lymphoma, SLE and lupus nephritis. Some case reports shows development of leprosy during/after biolo- gics treatment and success treatment of ENL with biologics. Collection of reports was done through web search by using document retrieval engine such as Pub-med and ProQuest...

BACKGROUND: Leprosy is an ancient chronic infection in the skin and peripheral nerves caused by Mycobacterium leprae. The development of leprosy depends on genetic background and the immune status of the host. However, there is no systematic view focusing on the biological pathways, interaction networks and overall expression pattern of leprosy-related immune and genetic factors. OBJECTIVES: To identify the hub genes in the center of leprosy genetic network and to provide an insight into immune and genetic factors contributing to leprosy...

Using a meta-analysis framework, we investigated the association between the NLRP3 rs35829419 polymorphism and increased susceptibility to diverse diseases in humans. Relevant published studies were identified through a comprehensive and systematic electronic search, using the following scientific literature databases: Science Citation Index, the Cochrane Library, PubMed, Embase, CINAHL, Current Contents Index, Chinese Biomedical, the Chinese Journal Full-Text, and the Weipu Journal. Statistical analysis of data extracted from the selected high quality studies was performed using the Version 12...

Erythema nodosum leprosum (ENL) is a severe multisystem immune mediated complication of borderline lepromatous leprosy and lepromatous leprosy. ENL is associated with skin lesions, neuritis, arthritis, dactylitis, eye inflammation, osteitis, orchitis, lymphadenitis and nephritis. The treatment of ENL requires immunosuppression, which is often required for prolonged periods of time and may lead to serious adverse effects. ENL and its treatment is associated with increased mortality and economic hardship. Improved, evidence-based treatments for ENL are needed; however, defining the severity of ENL and outcome measures for treatment studies is difficult because of the multiple organ systems involved...

BACKGROUND: Leprosy patients may present several osteoarticular complaints, which require further evaluation of inflammatory diseases, such as rheumatoid arthritis (RA). Therefore, an adequate clinical assessment in addition to testing for rheumatoid factors (RF) and anticyclic citrullinated peptide antibodies (anti-CCP), can be useful in order to establish the correct diagnosis. METHOD: In this study, the relation of RF and anti-CCP with rheumatological manifestations was evaluated in 97 leprosy patients from Southern Brazil...

Neutrophils form the most abundant leukocyte subset and are central to many disease processes. Technical challenges in transcriptomic profiling have prohibited genomic approaches to date. Here we map expression quantitative trait loci (eQTL) in peripheral blood CD16+ neutrophils from 101 healthy European adults. We identify cis-eQTL for 3281 neutrophil-expressed genes including many implicated in neutrophil function, with 450 of these not previously observed in myeloid or lymphoid cells. Paired comparison with monocyte eQTL demonstrates nuanced conditioning of genetic regulation of gene expression by cellular context, which relates to cell-type-specific DNA methylation and histone modifications...

INTRODUCTION: Leprosy is a chronic granulomatous infectious disease, which is caused by Mycobacterium leprae. High numbers of people are still affected by this disease in some of the developing countries however, it is rarely seen in non-endemic regions. Cutaneous and neurological manifestations are the common and classical presentations of leprosy. Musculoskeletal involvement is the third most common manifestation but is less frequently reported. Joint involvement can present as acute symmetrical polyarthritis or chronic polyarthritis resembling rheumatoid arthritis...

Mycobacterium haemophilum is a slow-growing non-tuberculous mycobacterium that is rarely known to cause human skin infection, particularly in immunocompromised patients. We recently experienced a 69-year-old Japanese woman with this infection who had been under immunosuppressive treatment for recalcitrant rheumatoid arthritis. The patient showed disseminated erythematous plaques and subcutaneous nodules on the face and extremities, and interestingly, the face manifested with a striking "facies leontina" appearance...

Leprosy is an infectious chronic disease with a wide range of clinical and serological manifestations. We report a case of a woman presenting with a malar rash, painless oral ulcers, photosensitivity, arthritis, positive antinuclear antibodies test and leuko-lymphopenia. Our case illustrates an unusual presentation of leprosy initially diagnosed as systemic lupus erythematosus (SLE). After the confirmation of multibacillary leprosy and multidrug therapy recommended by the World Health Organization, a good clinical response was observed...
