The disease manifests itself as vasculitis, which mainly affects the kidneys, lungs, skin and peripheral nerves. Microscopic polyangiitis may be associated with the presence of antiphospholipid syndrome, and is most often associated with positive tests for antineutrophil cytoplasmic antibodies (ANCA), in particular the myeloperoxidase type (MPO-ANCA). These antibodies are the main marker in diagnosis. <\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-flat ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Microscopic polyangiitis was first described in 1994, but its proven association with vasculitis was known much earlier. Evidence of pathological changes in small vessels can be found in the works of scientists such as Rudolf Virchow, who in the 19th century formulated the principle that \u201call diseases begin with the vessels\u201d. In the 1970s, the first studies were conducted on the role of ANCA in the pathogenesis of this disease. Interestingly, early studies emphasized the need to distinguish between microscopic polyangiitis and granulomatosis with polyangiitis (Wegener&#039;s disease), since they may have similar clinical manifestations, but differ in morphological and immune aspects. <\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Statistics on the disease show that microscopic polyangiitis occurs in approximately 3-10 cases per 1,000,000 population per year. According to studies, there has been a slight increase in the incidence in recent years, which may be due to increased awareness among doctors and improved diagnostic methods. The peak incidence is observed in the age group from 50 to 70 years, and the disease affects men and women equally. Differences in ethnic groups have also not been identified, however, the results of some studies show higher rates among the white population compared to people of other racial groups.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%BC%D1%83_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E\"><\/span>Genetic predisposition to this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To date, studies have not provided clear evidence of a hereditary predisposition to microscopic polyangiitis. However, a number of genes involved in the immune response and inflammatory processes continue to be studied. The main focus is on genes associated with HLA (histocompatibility, major complex), including HLA-DRB1 and associated variations, which may increase the risk of developing the disease. Some studies point to possible mutations in genes regulating cytokine production and angiogenesis, but without a clear link to preferential heredity. <\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Risk factors for the development of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are several risk factors that may hypothetically contribute to the development of microscopic polyangiitis:<\/p>\n<ul>\n<li>Environmental factors: Exposure to toxic chemicals such as pesticides and solvents may increase the risk of disease.<\/li>\n<li>Infectious agents: Certain viral and bacterial infections, particularly streptococcal and viral, have been reported to be associated with a high risk of vasculitis.<\/li>\n<li>Drug allergies: Reactions to certain drugs, such as antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs), can also serve as a trigger.<\/li>\n<li>Comorbidities: Having rheumatoid arthritis, systemic lupus erythematosus, and other autoimmune diseases may increase the likelihood of developing MP.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%94%D0%B8%D0%B0%D0%B3%D0%BD%D0%BE%D1%81%D1%82%D0%B8%D0%BA%D0%B0_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Diagnosis of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The main symptoms of microscopic polyangiitis range from mild to severe and may include:<\/p>\n<ul>\n<li>Hematuria and proteinuria are changes in urine tests that indicate renal involvement.<\/li>\n<li>Coughing up blood and shortness of breath are symptoms that indicate pulmonary pathology.<\/li>\n<li>Skin rashes including purpura and ulcers.<\/li>\n<li>Neurological signs: peripheral neuropathy and other neurological symptoms.<\/li>\n<\/ul>\n<p>Laboratory tests typically include:<\/p>\n<ul>\n<li>Complete blood count for anemia and inflammatory markers.<\/li>\n<li>Immunological tests for ANCA (a positive result is often key to diagnosis).<\/li>\n<li>Kidney biopsy to confirm the diagnosis of vasculitis.<\/li>\n<\/ul>\n<p>Radiological tests, such as chest X-rays and CT scans, can help detect changes in the lungs. <\/p>\n<p>Differential diagnosis includes other types of vasculitis, such as granulomatosis with polyangiitis and cryoglobulinemic vasculitis, as well as infectious and neoplastic diseases.<\/p><script data-noptimize=\"\" data-wpfc-render=\"false\">\nfpm_start( \"true\" );\n<\/script>\n\n<h2><span class=\"ez-toc-section\" id=\"%D0%9B%D0%B5%D1%87%D0%B5%D0%BD%D0%B8%D0%B5\"><\/span>Treatment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Treatment for microscopic polyangiitis is aimed at controlling inflammation and organ damage.
