Выделены две группы исследования: первая — 75 пациентов с преимущественно бронхитическим фенотипом заболевания (61 мужчина (81%) и 14 женщин (19%) в возрасте от 44 до 72 лет (средний возраст — 64, 0 ± 7, 8 года)),  вторая — 73 с преимущественно эмфизематозным фенотипом (56 мужчин (77%) и 17 женщин (23%) в возрасте от 54 до 72 лет (средний возраст — 64, 4 ± 6, 7 года)). Проведена оценка концентрации ММP-9, ММР-2, ТИМР-1 и ТИМР-2 при развитии ХОБЛ категории высокого риска обострений и в сопоставлении с клиническим фенотипом заболевания «сэндвич»-методом ИФА, в качестве варианта нормы использовали показатели группы контроля (здоровые).</p></sec><sec><title>Результаты</title><p>Результаты: развитие ХОБЛ категории высокого риска обострений сопровождается ростом концентрации ММР-2 и ММР-9 на фоне выраженного дисбаланса антипротеазной системы в пользу пропротеолитической активности с недостаточной выработкой ТИМР-1 и угнетением выработки ТИМР-2. При бронхитическом фенотипе определяется увеличение концентрации ММP-9 с 557 нг/мл до 1356 нг/мл, ММP-2 с 198 нг/мл до 213 нг/мл на фоне недостаточной выработки ТIМP-1 (менее 352, 5 нг/мл) и угнетения выработки ТIМP-2 (менее 98 нг/мл). Эмфизематозный фенотип ассоциирован с высокой эластолитической активностью ММP-9 (1357 нг/мл и выше) и ММP-2 (214 нг/мл и выше) на фоне нарастающего дефицита тканевых ингибиторов. Определена высокая (90%) диагностическая значимость уровня ММP-2 для дифференцировки фенотипов.</p></sec><sec><title>Заключение</title><p>Заключение: при развитии XOБЛ с частыми обострениями отмечается выраженная эластолитическая активность, максимально выраженная у больных с преимущественно эмфизематозным фенотипом. С целью дифференциальной диагностики клинических фенотипов у больных ХОБЛ категории высокого риска обострений необходимо использовать в качестве лабораторного критерия преимущественно эмфизематозного фенотипа концентрацию ММP-2 с пороговым значением более 214 нг/мл.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to assess the concentration of extracellular matrix markers MMP-2, MMP-9 and their tissue inhibitors TIMP-1, TIMP-2 in the development of COPD of the high-risk category of exacerbations.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: 148 patients with COPD of the high-risk category of exacerbations were examined, 114 of them were men (77%) and 34 were women (23%), the average age was 64.41 ± 6.72 years. Two study groups were identified: the first group consisted of 75 patients with a predominantly bronchitic phenotype of the disease: 61 men (81%) and 14 women (19%) aged 44 to 72 years (average age 64.0 ± 7.8 years); the second group consisted of 73 patients with a predominantly emphysematous phenotype: 56 men (77%) and 17 women (23%) aged 54 to 72 years (average age 64.4 ± 6.7 years). The concentrations of MMP-9, MMP-2, TIMP-1 and TIMP-2 were assessed in the development of COPD in the high-risk category of exacerbations and compared with the clinical phenotype of the disease by the "sandwich" ELISA method, the indicators of the control group (healthy) were used as the norm.</p></sec><sec><title>Results</title><p>Results: the development of COPD in the high-risk category of exacerbations is accompanied by an increase in the concentration of MMP-2 and MMP-9 against the background of a pronounced imbalance of the antiprotease system in favor of proproteolytic activity with insufficient production of TIMP-1 and inhibition of TIMP-2 production. In the bronchitic phenotype, an increase in the concentration of MMP-9 from 557 ng/ml to 1356 ng/ml, MMP-2 from 198 ng/ml to 213 ng/ml is detected against the background of insufficient production of TIMP-1 (less than 352.5 ng/ml) and inhibition of production of TIMP-2 (less than 98 ng/ml). The emphysematous phenotype is associated with high elastolytic activity of MMP-9 (1357 ng/ml and higher) and MMP-2 (214 ng/ml and higher) against the background of an increasing deficiency of tissue inhibitors. A high (90%) diagnostic significance of the MMP-2 level for the differentiation of phenotypes was determined. Conclusion: with the development of COPD with frequent exacerbations, pronounced elastolytic activity is noted, which is most pronounced in patients with a predominantly emphysematous phenotype. For the purpose of differential diagnosis of clinical phenotypes in patients with COPD of the high–risk category of exacerbations, it is necessary to use the concentration of MMP-2 with a threshold value of more than 214 ng/ml as a laboratory criterion for a predominantly emphysematous phenotype.</p></sec><sec><title>Conclusion</title><p>Conclusion: With the development of COPD with frequent exacerbations, pronounced elastolytic activity is noted, which is most pronounced in patients with a predominantly emphysematous phenotype.
