Systemic sclerosis (SSc) is an autoimmunological disease of unknown origin with complex pathogenesis and multiple organ involvement. It is characterised by vascular and immunological abnormalities leading to fibrosis of the skin and internal organs. It is a rather rare disease with a prevalence of around 20 per 100,000. The disease results in heterogeneous clinical findings and different courses. Systemic sclerosis usually begins with the onset of Raynaud's phenomenon (RP), followed by skin sclerosis and internal organ involvement, although it may appear synchronously with RP...

The role of epigenetic mechanisms in the regulation of the human RORγT gene, which encodes a Th17 lymphocyte signature transcription factor, remains largely unknown. We investigated the effect of histone deacetylase (HDAC) inhibition on RORγT and RORγT-dependent gene expression in human T lymphocytes. We found that, in Jurkat T cells and in in vitro-differentiated Th17 cells, treatment with 2 HDAC inhibitors, butyrate and apicidin, led to the induction of the RORγT gene, which was associated with an increase in histone H4 acetylation near the RORγT proximal promoter...

Usually limbic encephalitis (LE) is a paraneoplastic neurologic syndrome. LE symptoms can precede cancer even by a few years. Almost 50% of LE cases are connected with small cell lung carcinoma. Testis and breast cancers, granulomatous disease, thymoma, and teratomas are also often connected with LE. Other cases have infectious and autoimmunological aetiology. In LE limbic system dysfunction is observed, and it is accompanied by cerebellum and brain stem abnormalities as well as polyneuropathy. Paraneoplastic limbic encephalitis is sometimes a part of larger syndrome in which brain stem and spinal cord are involved in an inflammatory process called paraneoplastic encephalomyelitis...

Diagnostic technology is rapidly evolving, and over the last decade, substantial progress has been made even for the identification of antibodies, increasingly approaching this type of diagnostic to that of automated clinical chemistry laboratory. In this review, we describe the analytical and diagnostic characteristics of chemiluminescence technology in its strength and in its applicability for a more rapid and accurate diagnosis of autoimmune diseases. The wide dynamic range, greater than that of immunoenzymatic methods, the high sensitivity and specificity of the results expressed in quantitative form, the high degree of automation and the clinical implications related to the reduction in the turnaround time, and the ability to run a large number of antibody tests (even of different isotypes), directed towards large antigenic panels in random access mode, make this technology the most advanced in the clinical laboratory, with enormous repercussions on the workflow and on the autoimmunology laboratory organisation...

Advances in high-resolution mass spectrometers with faster scanning capabilities and higher sensitivities have expanded these instruments' functionality beyond traditional data-dependent acquisition in targeted metabolomics. Apart from the traditional multiple reaction monitoring strategy, the parallel reaction monitoring (PRM) strategy is also used for targeted metabolomics quantification. The high resolution and mass accuracy of full-scan (MS1) and tandem mass spectrometry (MS/MS) scan result in sufficient selectivity by monitoring all MS/MS fragment ions for each target precursor and simultaneously providing flexibility in assay method construction and post-acquisition data analysis...

BACKGROUND: In severe Sicca syndrome and limbal stem cell deficiency, vision can be restored by an artificial optical implant into the cornea (keratoprosthesis, KPro). After multiple efforts to achieve long-lasting corneal fixation of such an optical implant, two methods have become established: KPro with biological support, such as osteo-odonto-keratoprosthesis (OOKP) made from the root of patient's own tooth or osteo-keratoprosthesis (OKP), made from cortical bone of the patient's tibia; and the Boston KPro...

BACKGROUND: Psoriasis is known today as a T‑cell-mediated autoimmunological systemic disease. The chronic inflammatory processes involve neuroimmunological factors that are held responsible not only for various aspects of psychiatric-neurological comorbidities but also for neurosensory problems, primarily itching. Amongst other things, the significance of GABAA receptors are often discussed in this context. The topical use of chloral hydrate in semisolid preparations for antipruritic therapy goes back to Neisser and is currently experiencing a revival in individually manufactured formulations...

Aortoesophageal fistulas (AEFs) are rare and life-threatening conditions. Till date, an association between an AEF and sarcoidosis has not been reported yet. The aim of this report is to demonstrate a case of AEF secondary to sarcoidosis and its multistage interdisciplinary surgical therapy. A 66-year-old male was diagnosed with sarcoidosis in 2014. He has been treated with glucocorticoids since then and no severe health restrictions due to the disease have occurred. In December 2015, the patient presented with acute thoracic pain and hematemesis: an esophagogastroscopy revealed an AEF...

Alopecia areata (AA) is one of the most common causes of non-scarring hair loss, which is associated with the premature induction of hair follicle regression. The pathogenesis of AA is unknown, although it is believed that a complicated autoimmune mechanism with Th1 lymphocytes and proinfammatory cytokines, such as IFN-γ, TNF-α, IL-1 and IL-2, may be involved. AA may occur as a single disease entity or coexist with other autoimmunological disorders. In some cases the relationship with infammatory bowel disease (IBD) was observed and the link between molecular pathways and main proinfammatory cytokines in IBD and AA has been suggested...

Over three last decades, it has been noticed that morbidity of immunology-dependent illnesses, like asthma, inflammatory bowel disease or atopic dermatitis, apparently increased. That is the reason to focus on searching and exploring new ideas which could explain etiopathology of those diseases. In etiopathology the role of environmental factors is particularly emphasized. Research indicated the inverse relationship between the frequency of infectious and/ or parasites and autoimmune diseases. It was a leading subject of many studies what allowed to create a hypothesis which explains the phenomenon...

Myasthenia gravis (MG) is an autoimmunological inflammatory disorder of the neuromuscular junction. Inflammation could be a key player for understanding the pathogenesis of MG. We measured the serum levels of 24 inflammatory cytokines in 43 patients with anti-acetylcholine receptor antibody-positive MG and 25 healthy controls. In patients with MG, serum levels of a proliferation-inducing ligand (APRIL), IL-19, IL-20, IL-28A and IL-35 were significantly increased as compared with controls (p < 0.05). Among them, IL-20, IL-28A and IL-35 were significantly decreased after treatment (p < 0...
