INCIDENCE OF PSORIATIC ARTHRITIS IN RUSSIA: TRENDS AT THE PRESENT STAGE AND PROSPECTS

The diseases that are hazardous to the health of our planet's population and to the state of national economies should include psoriasis and psoriatic arthritis (PsA). This disease has been recorded in the official statistics of the Ministry of Health of Russia since only 2009. In 2011 in the Russian Federation as whole, the incidence of PsA, or arthropathic psoriasis (according to the International Classification of Diseases (ICD)), was 12.3 per 100,000 population or 5.7% of all registered psoriasis cases, which was substantially lowerthan that in other countries. Due to the lack of sufficient information on the epidemiology of PsA in the Russian population, the objective of this investigation was to study agerelated and regional trends in the incidence of this disease in the Russian Federation.

Material and methods. The incidence of PsA was analyzed using the data from annual statistical registered form No. 12 of the Ministry of Health of Russia over 2009–2013. The overall and primary morbidity rates of PsA among children and adults were analyzed in intensive values per 100,000 population. The prevalence of PsA and the rate of its incidence increment were analyzed in the Russian Federation's districts and subjects.

Results and discussion. The analysis showed a modest increase in overall morbidity rates of PsA in the Russia as a whole over the five years along with a decrease in the rates in the class as a whole. This suggests the disease severity that forces patients to seek medical advice. The situation associated with PsA morbidity among children and adults differs essentially in Russia's regions. The gap between in child and adult rates indicates that there are organizational problems in dermatovenereological care to the pediatric and adult populations in these regions. The alarming fact is that one-third of psoriatic patients experience joint pain and only 8% are diagnosed as having PsA, which also points to the inadequate diagnosis of this disease.The official statistical data on the incidence of PsA in the Russian Federation greatly differ from the results of international epidemiological surveys, which may be associated both with poor record keeping and diagnostic problems. The established situation may be improved by elaborating and introducing a diagnostic algorithm for PsA, by carrying out prophylactic examinations of psoriatic patients within mandatory health insurance in order to reveal the clinical signs of the disease, by timely examining the patients by a rheumatologist, and by creating the routing of the patients at all sociomedicalcare levels, and by simultaneously improving thesystem for the organizational recording of PsA cases in the country as a whole.
