Conclusion. There is a significant relationship between the studied polymorphic variants of the APOC3, PON1, AGT, AGTR1 genes and vascular control parameters in the context of orthostasis. It may be a predictor of early development of arterial hypertension.
Aim. To assess the diagnostic value of the detection of soluble transferrin receptors (sTfR) and ferritin index (sTfR/log Fer) in patients with spondyloarthritis (SpA) and anemia for the revealing absolute iron deficiency (ID). Materials and methods. The study included 68 patients with SpA: median age 39 [34; 47] years, men: 38 (55.9%). Hemogram, C-reactive protein levels and ferrokinetics parameters were assessed, including sTfR testing by the method of quantitative enzyme-linked immunosorbent assay (Monobind Inc., USA). We also calculated sTfR/log Fer. Based on ferrokinetics parameters and C-reactive protein levels, chronic disease anemia (CDA), iron deficiency anemia (IDA), or their combination (CDA/IDA) were diagnosed. Results. CDA was diagnosed in 16 patients, CDA/IDA in 32 patients, and 20 patients had no anemia. An increase in sTfR concentration in patients with CDA/IDA (1.7 [1.4; 2.2] mg/L) compared with patients with CDA (1.5 [1.1; 1.7] mg/L, p0.05) was revealed. sTfR/log Fer in patients with CDA/IDA (0.93 [0.82; 1.24]) was higher than in patients with CDA (0.64 [0.48; 0.75], p0.0001). When evaluating the ROC curves, it was found that sTfR levels 1.39 mg/L and sTfR/log Fer levels 0.83 indicate the presence of absolute ID. The area under the ROC curve for sTfR was 0.72 (95% confidence interval 0.600.82, p0.001), for sTfR/log Fer 0.85 (95% confidence interval 0.740.92, p0.001). The sensitivity and specificity of sTfR/log Fer (75 and 83%, respectively) were higher compared with sTfR (53 and 81%, respectively). Conclusion. In patients with SpA having CDA/IDA, sTfR and sTfR/log Fer are statistically significantly increased. The results obtained indicate the possibility of diagnosing ID by using these parameters.
Aim. To assess the relationship between the activity of systemic inflammation and the hemoglobin level in patients with spondyloarthritis (SpA).Materials and methods. We examined 92 patients with SpA aged 42.9 ± 11.6 years (SpA duration – 14.8 ± 9.6 years, 55 (60%) men). We calculated the BASDAI and ASDAS-CRP scores, performed complete blood count, evaluated erythrocyte sedimentation rate (ESR), ferrokinetic parameters, C-reactive protein (CRP) level, and serum concentrations of tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6).Results. Anemia was found in 52 (57%) patients: 13 (25%) patients were diagnosed with anemia of inflammation (AI), 39 (75%) individuals had a combination of AI and iron deficiency anemia. A significant increase in CRP (17.8 vs. 9.0 mg / l, respectively; p = 0.001) and ESR (23 vs. 10 mm / h, p < 0.001), a tendency toward an increase in IL-6 levels (5.4 vs. 4.1 pg / ml, p = 0.051), and no difference in TNF-α levels (3.4 vs. 3.0 pg / ml, p = 0.245) were revealed in patients with anemia compared with patients with normal hemoglobin level. The hemoglobin concentration was negatively correlated with the CRP level (r = –0.327, p = 0.001) and ESR (r = –0.527, p < 0.001). IL-6 was positively correlated with the levels of TNF-a, CRP, and ESR (r = 0.431, r = 0.361, r = 0.369; all p < 0.001). With the IL-6 concentration >10 pg / ml, the odds for anemia were 5.3 times higher (95% confidence interval: 1.4–19.9, p = 0.009).Conclusion. The relationship between the activity of systemic inflammation and anemia in patients with SpA was confirmed. Taking into account the pathogenesis of AI, the aim of antianemic treatment is to achieve remission or minimal activity of SpA. Additional studies are required to determine the effect of anti-inflammatory therapy on the development and course of anemia in patients with SpA.
Цельопределить клинико-лабораторные взаимосвязи уровня растворимого стимулирующего фактора роста, экспрессирующегося геном 2 (sST2), с показателями, характеризующими развитие сердечно-сосудистой патологии у пациентов со спондилоартритами (СпА). Материалы и методы. Обследовано 46 пациентов со СпА, из них 40 (87 %) с анкилозирующим спондилитом, 6 (13 %) -с псориатическим артритом. Средний возраст пациентов -39,2±10,2 лет. Среди обследованных 36 (78,3 %) мужчин, 10 (21,7 %) женщин. Из 32 обследованных пациентов у 27 (84,4 %) выявлен HLA-B27. Для оценки активности СпА использовали индексы BASDAI и ASDAS, учитывали значения скорости оседания эритроцитов и С-реактивного белка; определяли уровни фактора некроза опухоли-альфа, N-терминального фрагмента мозгового натрийуретического пептида (NT-proBNP), интерлейкина-6, sST2 в сыворотке крови. Оценивали традиционные факторы сердечно-сосудистого риска, скорость распространения пульсовой волны в аорте (СПВА), результаты стандартной электрокардиографии, трансторакальной эхокардиографии, дуплексного исследования сонных артерий. Результаты. Средний уровень sST2 составил 33,34±11,2 нг/мл, уровень sST2 выше порогового значения зафиксирован у 19 (41,3 %) пациентов. Значимых взаимосвязей между уровнем sST2 и показателями активности СпА, параметрами эхокардиографии, нарушениями ритма и/или проводимости на электрокардиограммах не обнаружено. У пациентов с уровнем sST2 выше среднего отмечена более высокая СПВА (р=0,036); уровень NT-proBNP чаще был повышен у пациентов с высоким уровнем sST2 (р=0,085). У пациентов, получающих генно-инженерные биологические препараты в связи с высокой активностью СпА, отмечены более высокие уровни sST2 (р=0,039). Заключение. У 41,3 % пациентов со СпА установлен уровень sST2 выше порогового значения. Повышение уровня sST2 ассоциируется с увеличением СПВА и повышением уровня NT-proBNP, что может свидетельствовать о начавшихся процессах ремоделирования миокарда, фиброзе миокарда и начальных этапах развития сердечной недо-
