OBJECTIVE: The low-dose intravenous (IV) cyclophosphamide (CY) Euro-Lupus (EL) regimen (cumulative dose of 3 g) was developped to reduce gonadal toxicity. To address the possibility of a marginal effect on the ovarian reserve, we measured serum anti-Müllerian hormone (AMH) titers in patients suffering from systemic lupus erythematosus (SLE) treated with the EL regimen and compared them to those measured in patients treated with higher doses of IVCY or never treated with IVCY. METHODS: Serum AMH levels were measured by ELISA in a cohort of 155 premenopausal SLE patients, of whom 30 had received the EL regimen and 24 higher doses of IVCY...

Antiviral defenses are inappropriately activated in systemic lupus erythematosus (SLE) and association between SLE and the antiviral helicase gene, IFIH1, is well established. We sought to extend the previously reported association of pathogenic soluble mediators and autoantibodies with mouse Mda5 to its human ortholog, IFIH1. To better understand the role this gene plays in human lupus, we assessed association of IFIH1 variants with soluble mediators and autoantibodies in 357 European-American SLE patients, first-degree relatives, and unrelated, unaffected healthy controls...

Polyglandular autoimmune syndromes encompass several endocrine and nonendocrine autoimmune disorders with variable onset and phenotype. Rheumatoid and gastroenterological symptoms in patients with autoimmune polyglandular syndromes are suggestive of additional rheumatoid gastrointestinal and hepatological autoimmune diseases. Autoimmune gastritis, celiac disease, autoimmune hepatitis, rheumatoid arthritis, Sjögren syndrome, and systemic Lupus erythematodus are of particular clinical relevance. In addition, unspecific rheumatoid and gastrointestinal attendant symptoms of the existing autoimmune endocrinopathy must be considered...

Lupus erythematosus, especially the discoid form, and lichen planopilaris may be associated and can occur in different topographies (coexistence) or in the same lesion (lupus eythematosus/lichen planus overlap syndrome). Frontal fibrosing alopecia is considered a variant form of lichen planopilaris and is characterized by frontotemporal hairline and eyebrow involvement. Of the association with lupus erythematosus we have only a few descriptions. Hydroxychloroquine and chloroquine diphosphate are antimalarial drugs described as viable treatment options for both diseases, due to an antilymphocytic effect...

MicroRNAs (miRNAs) are important regulators of gene expression, and the dysregulation of miRNAs is a common feature of several diseases. More miRNAs are identified almost daily, revealing the complexity of these transcripts in eukaryotic cellular networks. The study of renal miRNAs, using genetically modified mice or by perturbing endogenous miRNA levels, has revealed the important biologic roles miRNAs have in the major cell lineages that compose the glomerulus. Here, we provide an overview of miRNA biogenesis and function in regulating key genes and cellular pathways in glomerular cells during development and homeostasis...

BACKGROUND: Systemic Lupus Erythematosus (SLE) is a serious multisystem autoimmune disease, which is more aggressive in children and people of African descent. In South Africa, pediatric SLE (pSLE) patients are at high risk for severe disease. Similar to pSLE worldwide, South African children and adolescents with SLE require subspecialized medical care. The aim of this study is to describe the care-seeking experiences of families and examine factors that contribute to delays in the diagnosis of pSLE...

Systemic lupus erythematosus (SLE) is a heterogeneous disease with a vast variety of clinical manifestations. Timely diagnosis is important for gaining access to specific therapy and care. In this survey, we asked SLE patients with an established diagnosis to report about their personal history and their daily life with SLE in order to gain knowledge about diagnostics, treatment pathways and potential problems in daily living and functioning. In most cases, the diagnosis of SLE was made by a specialist in rheumatology or dermatology...

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with multiorgan inflammation, linked to the loss of immune tolerance to self-antigens and the production of a diversity of autoantibodies. The phenotype and progression of SLE have been linked to a combination of environmental, genetic, and hormonal factors. One such environmental factor is vitamin D, a vital hormone with well-established effects on mineral metabolism, skeletal health, and effects on cardiovascular system. The purpose of this article is to make the analysis of evidence and literature review of the pleomorphic effects of Vitamin D in SLE...

Toxoplasma gondii is a zoonotic protozoan parasite that infects a wide range of warm-blooded animals throughout the world. In the present study, antibodies to T. gondii were determined using a commercial indirect hemagglutination (IHA) test in wild animals in a zoo. Three of 11 giraffes (Giraffa camelopardalis) (27%), 1 of 5 wolves (Canis lupus laniger) (20%), 1 of 6 hippopotamuses (Hippopotamus amphibious) (17%), and 2 of 9 tundra swans (Cygnus columbianus) (22%) were found to be positive. No antibodies were detected in leopards (Panthera pardus), wild geese (Anser cygnoides), and Eastern grey kangaroos (Macropus giganteus)...

Regulatory T cells (Tregs) are critical mediators of immune tolerance, yet their involvement in the autoimmune disease systemic lupus erythematosus (SLE) is incompletely understood. We analyzed CD4(+) T cell subpopulations with Treg-related phenotypes and their association with disease activity in peripheral blood (PB) and tissues of patients with SLE. In detail, we quantified subpopulations regarding CD25, FOXP3, CD62L, CCR6, CD27, CD45RA, and CD45RO expression in PB from 31 patients with SLE divided into two disease activity groups and 32 healthy controls using flow cytometry...

The senescence-accelerated mouse prone 8 (SAMP8) strain is considered a robust experimental model for developing preventative and therapeutic treatments for Alzheimer's disease (AD), a neurodegenerative disease which cannot be effectively prevented, halted, or cured. Our previous studies showed that LW-AFC, a new formula derived from the classical traditional Chinese medicinal prescription Liuwei Dihuang decoction, ameliorates cognitive deterioration in PrP-hAβPPswe/PS1ΔE9 transgenic mice and SAMP8 mice. This study aims to investigate the mechanism that mediates how LW-AFC improves cognitive deficit on the basis of the transcriptome...
