Abstract: MicroRNAs (miRNAs) are 18–25 nucleotide long, single stranded, endogenous, non-coding small RNAs playing an important role in regulating gene expression at posttranscriptional level. miRNAs control approximately 90% of protein-coding genes, and play a central role in various biological processes including immune cell lineage commitment, differentiation, proliferation, apoptosis and maintenance of immune homeostasis. Changes in the expression of certain miRNAs may lead to the development of many diseases, including systemic autoimmune diseases. In this study, we summarize the biogenesis of miRNAs, their role in regulation of the immune system, and review the latest research findings in systemic lupus erythematosus, primary Sjögren’s syndrome, rheumatoid arthritis and systemic sclerosis. In the future, miRNAs may help not only in establishing diagnosis and prognosis but potentially serve as targets for modern therapeutic approaches in autoimmune diseases.

Atherosclerosis is a systemic disease affecting the coronary, carotid, intracerebral, renal and peripherial arteries. The early morphological and functional impairments could be detected in the second or third decades of life and their progression depend on the number and severity of risk factors and individual susceptility. Although the vascular risk factors (smoking, overweight, age, unhealthy diet, lack of physical exercise, hypertension, diabetes mellitus, chronic kidney disease and dyslipidemia) are the same and common in the different vascular diseases, the present clinical routine artificially classifies the diagnosis and therapy of different vascular diseases into different subfields of medicine with the negative impact of possible polypragmasia. Recently, worldwide health surveys (e.g. REACH registry) have proven the usefulness of a holistic approach in the diagnosis and therapy of multiorgan-affected vascular patients. This review summarizes the multidisciplinary advances and future perspective of vascular diseases. Orv. Hetil., 2012, 153, 483–498.

A szisztémás lupus erythematosus poliszisztémás autoimmun betegség, egyik legjelentősebb szervi szövődménye a lupus nephritis. A lupus nephritis időbeni, a krónikus szervi érintettség kialakulását megelőző felismerése, a shubok előrejelzése, a korai agresszív kezelés elkezdése és a terápia sikerességének lemérése kívánatos lenne. Ezért a kutatások egy része intenzíven a legmegfelelőbb, aktivitást előre jelző biomarker megtalálására irányul. Jelen összefoglaló célja a hagyományos szerológiai markerek megbeszélésén túl a legújabb, részben még kísérletes, a klinikai gyakorlatban nem használt, de az SLE, illetve lupus nephritis aktivitását jellemző specifikus biomarkerek bemutatása.

Ramsay Hunt syndrome is a special form of herpes zoster which is typically characterized by peripheral facial palsy and unilateral herpetic vesicles on the ear. These symptoms are often accompanied by vestibulocochlear dysfunction and other neurological and ophthalmological symptoms. The diagnosis and therapy requires a multidisciplinary approach. The authors present a typical case where the early administration of combined antiviral and systemic corticosteroid therapy led to complete recovery. The authors emphasize the importance of early diagnosis and adequate combination therapy, which improves the prognosis of this disease. Orv. Hetil., 2012, 153, 1281–1283.
