Изменения клеточного и гуморального иммунитета у пациентов с холодовой и хронической спонтанной крапивницей

Изменения клеточного и гуморального иммунитета у пациентов с холодовой и хронической спонтанной крапивницей

Abstract

Objectives. To estimate the condition of the cellular and humoral link of the immune system in patients with cold and chronic spontaneous urticaria. Material and methods. 126 patients of the allergological department of Vitebsk regional clinical hospital participated in the research: 47 patients with cold urticaria at the age of 47,0 (38,0-52,0) years and 79 persons aged 43,0 (28,0-51,0) with chronic spontaneous urticaria. The control group consisted of 38 healthy volunteers at the age of 42,5 (34,5-54,0) years. The research program has been approved by the ethics committee. In all patients prior to the beginning of their treatment on an empty stomach samples of blood were taken to determine the quantity and phenotype of leukocytes, the level of immunoglobulins. Phenotyping of the cells was conducted with the help of monoclonal antibodies CD19, CD23, CD3, CD4, CD25, CD8, CD69, CD203с (complex test systems for scientific and clinical researches «Bioskan-M1») using Cytomics FC 500 (Beckman Coulter Inc., the USA) cytometer. Results. The immune status of patients with cold urticaria in the exacerbation period was characterised by the decrease in the absolute quantity of CD3 + and CD4 + CD25 + lymphocytes of the peripheral blood. The immune status of the patients with chronic spontaneous urticaria in the exacerbation period was characterised by the decrease in the absolute quantity of CD4 + CD25 + lymphocytes of the peripheral blood, the increase of the relative amount of CD19 + CD23 + lymphocytes of the peripheral blood and the increase of the absolute quantity of CD203с of positive basophils. In patients with chronic spontaneous urticaria immunoglobulin M was within the limits of the population norm, but its concentration was higher than that in the group of healthy people. Conclusion. In patients with cold and chronic spontaneous urticaria in the exacerbation period of the disease the high degree deficiency of CD4 + CD25 + lymphocytes taking part in the development of bothtypes of urticaria was revealed.

Цель исследования оценка клеточного и гуморального звена системы иммунитета у пациентов с холодовой и хронической спонтанной крапивницей. Материалы и методы. В исследовании участвовали 126 пациентов аллергологического отделения Витебской областной клинической больницы: 47 пациентов с холодовой крапивницей в возрасте 47,0 (38,0-52,0) лет; 79 пациентов с хронической спонтанной крапивницей в возрасте 43,0 (28,0-51,0) года. В контрольную группу были включены 38 здоровых добровольцев в возрасте 42,5 (34,5-54,0) года. Программа исследования была утверждена комитетом по этике. У всех пациентов до начала лечения натощак была взята кровь для определения количества и фенотипа лейкоцитов, уровня иммуноглобулинов. Фенотипирование клеток проводили с помощью моноклональных антител CD19, CD23, CD3, CD4, CD25, CD8, CD69, CD203с (комплексных тест-систем для научных и клинических исследований «Биоскан-М1» (ОДО «НИКП РЕСАН», Беларусь)), на проточном цитометре Cytomics FC 500 (Beckman Coulter Inc., США). Результаты. Иммунный статус пациентов с холодовой крапивницей в период обострения характеризовался снижением абсолютного количества CD3 + и CD4 + CD25 + лимфоцитов периферической крови. Иммунный статус пациентов с хронической спонтанной крапивницей в период обострения характеризовался снижением абсолютного количества CD4 + CD25 + лимфоцитов периферической крови, повышением относительного количества CD19 + CD23 + лимфоцитов и повышением абсолютного количества CD203с позитивных базофилов. У пациентов с хронической спонтанной крапивницей концентрация иммуноглобулина М находилась в границах популяционной нормы, но его концентрация была выше, чем в группе здоровых людей. Заключение. У пациентов с холодовой и хронической спонтанной крапивницей в период обострения заболевания выявлен тяжелый дефицит регуляторных CD4 + CD25 + лимфоцитов, которые принимают участие в развитии обоих типов крапивницы.
