У 48 пациентов с достоверным диагнозом анкилозирующий спондилит в возрасте от 18 до 69 лет, получавших лечение ингибиторами фактора некроза опухоли альфа (ФНО-α) и нестероидными противовоспалительными препаратами (НПВП), оценивалась активность заболевания (по индексам ASDAS-СРБ, BASDAI и уровню С-реактивного белка), определялась концентрация IgA анти-CD74 в сыворотке крови; изучались полиморфизмы генов И.'1-17Л197 a/g, ИЛ-17Г7 гистидин (His)/аргинин (Arg), ИЛ-17И1139 c/g, ФНОа-863, ФНОα-308, ФНОα-238, ИЛ-1В-31, ИЛ-4-590, ИЛ-6-174, ИЛ-10-1082, ИЛ-10-592, VEGF-2578, VEGF-936, MMP2-1306, MMP3-5A6A, MMP9-1562, HLA-B27.</p></sec><sec><title>Результаты</title><p>Результаты. Средний возраст пациентов составил 45,1±14,2 года (мужчины составили 72,9%, псориаз выявлен у 10,4%, воспалительные заболевания кишечника — у 2,1% больных). BASDAI составлял в среднем 2,99±0,28, ASDAS-СРБ - 2,29±0,16, СРБ - 6,5±1,65 мг/л, анш-СВ74 - 18,6±1,73 Ед/мл (у 72,9% пациентов &gt;12 Ед/мл). При выполнении факторного анализа обнаружена связь повышения уровня IgA анти-CD74 сыворотки крови с индексами активности ASDAS-СРБ и BASDAI, повышения уровня СРБ с наличием генотипа ИЛ-nA гетерозиготного по аллелю АА (r =0,965), не выявлена взаимосвязь СРБ с индексом активности BASDAI. Носительство аллеля И.'1-171;-11139 СС ассоциировалось с наличием псориаза (r=0,870).

In 48 patients with a reliable diagnosis of ankylosing spondylitis, aged 18 to 69 years were measured the ASDAScrp, BASDAI, level of highly sensitive С-reactive protein, concentration of IgA anti-CD74. The polymorphisms of the genes interleukin (IL)-17A197 a/g, IL-17F7 histidine (His) / arginine (Arg), IL-17F11139 c/g, TNF-a-863, TNFα-308, TNFα-238, IL-1B-31, IL- 4-590, IL-6-174, IL-10-1082, IL-10-592, vascular endothelial growth factor (VEGF)-2578, VEGF-936, matrix metalloproteinase (MMP)2-1306, MMP3-5A6A, MMP9-1562, HLA-B27 were evaluated in their relationships with AS activity and IgA anti-CD74 levels.</p></sec><sec><title>Results</title><p>Results. The mean age of patients was 45.1±14.2 years, male - 72.9%, psoriasis - 10.4%, IBD - 2.1%, BASDAI -2.99±0.28, ASDAS - 2.29±0.16, CRP - 6.5±1.65 mg/L, IgA эпй-СВ74 - 18.6±1.73 U/mL (72.9% of the patients with &gt;12 U/mL). The relationship between an increase in concentration of IgA anti-CD74 and ASDAScrp, BASDAI activity indices, between an increase in the level of CRP and the presence of the IL-17A genotype heterozygous for the AA allele (r=0.965) was determined. CRP did not demonstrate the relationship with the BASDAI.</p><p>An association of IL-17F-11139 СС and the presence of psoriasis (r=0.870) was established. 93.8% of patients with ankylosing spondylitis were carriers of the homozygous histidine allele IL-17F7 (his/his) and the TNF238 allele (GG).</p></sec><sec><title>Conclusions</title><p>Conclusions. The increase in anti-CD74 IgA level was found in 72.9% of patients with ankylosing spondylitis receiving inhibitors of TNF-a and NSAIDs and associated with clinical and laboratory indicators of ankylosing spondylitis activity and with carriage of the homozygous histidine allele IL-17F7 (his/his) detected in 93.8% of patients.
