Rheumatoid factor (RF) is used in human and veterinary medicine in the form of IgM RF traditionally to support the diagnosis of rheumatoid arthritis (RA). In the latest diagnostic criteria, presence of anti - citrullinated protein antibodies (ACPA) was added to the grading system for the diagnosis of RA in humans. A change which is not integrated or routinely used in veterinary medicine. The criteria changed partly because of RF's diagnostic shortcomings, which include its increased titer detection in humans with non-rheumatoid diseases, inability to predict the disease and increased titers over the limit in the older population. Clinical signs similar to human RA were reported in horses in a condition known as idiopathic polysynovitis. Similarities in the clinical presentation to RA raised a question to the usability of RF and ACPA in horses. In our study, sixty clinically healthy horses, ranging from 3 days to 30 years of age, were evaluated for their serum levels of IgM RF. 55 of these horses were tested for ACPA, using methods of ELISA measuring Anti - CFG (Anti citrullinated fibrinogen antibody). The results of the study demonstrated the existence of an age-dependent increase in the level of IgM RF up to the age of about 9 years and ACPA's independence of the horse's age as well as both markers independence of the horse sex.

Maligní nádory mohou být provázeny paraneoplastickými revmatickými syndromy, které vznikají bez přímé invaze nádorových buněk do tkání a jsou způsobeny humorálními mediátory. Těchto syndromů byla popsána celá řada – mezi nejčastější patří hypertrofická osteoartropatie, karcinomatózní polyartritida, dermatomyozitida a paraneoplastická vaskulitida. Vzácněji se vyskytují fascitida, panikulitida, Raynaudův syndrom, digitální gangréna, erytromelalgie, Lambert-Eatonova myastenie a další. Seznam revmatických syndromů spojených se zhoubnými procesy se stále rozšiřuje a nově jsou do této skupiny zařazovány rovněž benigní edematózní polysynovitida, neutrofilní dermatózy, osteomalacie a antifosfolipidový syndrom. Muskuloskeletální příznaky se mohou objevit současně, před či po manifestaci národového procesu a mohou rovněž předpovídat jeho rekurenci. Klinické projevy obvykle kopírují průběh primárního nádorového onemocnění, jehož léčba často vede k vymizení revmatických příznaků. Muskuloskeletální projevy mohou upozornit na přítomnost skrytého nádorového procesu a umožnit jeho včasnou detekci a zahájení terapie. Předložené sdělení podává přehled paraneoplastických revmatických syndromů a zabývá se mechanismy jejich vzniku, klinickým obrazem a léčebnými možnostmi.
Malignant tumours may be associated with paraneoplastic rheumatic syndromes which develop without direct invasion of tumour cells into tissues and are caused by humoral mediators. A number of these syndromes was described – the most frequent ones include hypertrophic osteoarthropathy, carcinomatous polyarthritis, dermatomyositis and paraneoplastic vasculitis. Less frequently fascitis, Raynaud's syndrome, digital gangrene, erythromelalgia,Lambert-Eaton'smyasthenia andothers are encountered. The list of rheumatic syndromes associated with malignant processes is extending steadily and recently in this group also benign oedematous polysynovitis, neutrophil dermatoses, osteomalacia and antiphospholipid syndrome are included.Musculoskeletal symptoms may develop concurrently with, before or after manifestation of the tumorous process and may also predict its recurrence. Clinical manifestations copy as a rule the course of the primary tumourous disease the treatment of which frequently leads to disappaearance of rheumatic symptoms. Musculoskeletal manifestations may draw attention to the presence of a latent tumorous process and make its early detection and initiation of therapy possible. The submitted paper reviews paraneoplastic rheumatic syndromes and is concerned withmechanisms of their development, clinical picture andtherapeutic possibilities.
