В последние годы прогресс в понимании генетических механизмов, лежащих в основе предрасположенности к дегенеративной патологии позвоночника, был достигнут благодаря достижениям молекулярной генетики.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: провести сравнительный анализ частот генотипов и аллелей генов коллагена I типа (COL1A1 C-1997A (rs110946) А &gt; С, COL1A1 G-1245T (rs1800012) G &gt; T) и рецептора витамина D (VDR: 283 (Bsml) A &gt; G) у пациентов молодого возраста с хронической скелетно-мышечной болью в спине.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Основную группу составили 70 пациентов (39 женщин и 31 мужчина, средний возраст 40 [38; 43] лет) с хронической (более 3 мес.) скелетно-мышечной болью в области спины. Группу сравнения составили 16 здоровых лиц (8 женщин и 8 мужчин, средний возраст 35 [31; 40] лет). Определение полиморфизма гена VDR: 238 (Bsml) проводили в режиме реального времени методом полимеразной цепной реакции (ПЦР) на амплификаторе ДТ-лайт (ДНК-Технология, Россия) с использованием наборов реагентов «Генетика метаболизма кальция» (ДНК-Технология, Россия). Определение полиморфизмов генов коллагена проводили методом ПЦР на ампфликаторе Real-time CFX96 Touch (Bio-Rad Laboratories, США) с использованием наборов реагентов производства «Синтол» (Россия). Статистический анализ полученных данных выполнялся с использованием программного пакета SPSS Statistics 19. Частоту вариантов аллелей вычисляли по формуле f = n/2N, частоту генотипов — по формуле f = n/N (где N — объем выборки, n — встречаемость вариантов). Статистическую значимость частот аллелей и генотипов оценивали с помощью критерия ꭓ2 . Для оценки относительного риска использовали расчет отношения шансов (ОШ) и его доверительного интервала (ДИ) при уровне 95%: ОШ = ДE/HE/ДNE/HNE, где ДE и HE — количество пациентов в основной группе и контрольной группе, у которых фактор присутствовал, ДNE и HNE — количество пациентов без фактора риска.</p></sec><sec><title>Результаты</title><p>Результаты. Пациенты с хронической скелетно-мышечной болью в области спины отличались от группы здоровых лиц более высокой частотой встречаемости плоскостопия (р = 0,022), сколиоза позвоночника (р = 0,005), повышенной хрупкости ногтей (р = 0,000) и близорукости (р = 0,25). Установлено, что хроническая скелетно-мышечная боль в спине у молодых пациентов находится в генетической связи с аллелем А гена рецептора витамина D (VDR: 283 (Bsml)) (χ2 = 6,779; р = 0,020; ОШ = 4,308; 95% ДИ [1,363; 13,616]).</p></sec><sec><title>Заключение</title><p>Заключение. Наличие аллеля А гена рецептора витамина D (VDR: 283 (Bsml)) у молодых пациентов ассоциируется с генетически обусловленной более высокой восприимчивостью к развитию скелетно-мышечной боли в спине.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. In recent years, progress in understanding the genetic mechanisms underlying susceptibility to degenerative spinal pathology has been achieved due to advances in molecular genetics.</p></sec><sec><title>Objective</title><p>Objective: conduct a comparative analysis of the genotypes and alleles frequencies of type I collagen genes (COL1A1 C-1997A (rs110946) A &gt; C, COL1A1 G-1245T (rs1800012) G &gt; T) and vitamin D receptor (VDR: 283 (Bsml) A &gt; G) in young patients with chronic musculoskeletal back pain.</p></sec><sec><title>Material and methods</title><p>Material and methods. The main group consisted of 70 patients (39 women and 31 men, average age 40 [38; 43] years) with chronic (more than 3 months) musculoskeletal back pain. The control group consisted of 16 healthy individuals (8 women and 8 men, average age 35 [31; 40] years). Determination of the VDR: 238 (Bsml) gene polymorphism was carried out in real time by the polymerase chain reaction (PCR) method on a DT-light amplifier (DNA-Technology, Russia) using reagent kits “Genetics of calcium metabolism” (DNA-Technology, Russia). Determination of collagen gene polymorphisms was carried out by PCR on a Real-time CFX96 Touch amplifier (Bio-Rad Laboratories, USA) using reagent kits produced by Synthol (Russia). Statistical analysis of the obtained data was performed using the SPSS Statistics 19 software package. An allele frequency was calculated by using the formula f = n/2N, the genotypes frequency — by using the formula f = n/N (where N is the sample size, n is the prevalence of variants). The statistical significance of allele and genotype frequencies was assessed using the ꭓ2 criterion. We calculated the odds ratio (OR) to assess the relative risk and its 95% confidence interval (CI): OR = DE/HE/DNE/HNE, where DE and HE are the number of patients in the main and control groups with the risk factor, DNE and HNE — the number of patients without a risk factor.</p></sec><sec><title>Results</title><p>Results. Patients with chronic musculoskeletal back pain differed from the healthy individuals in a higher incidence of fl at feet (p = 0.022), spinal scoliosis (p = 0.005), increased fragility of the nail plate (р = 0.000) and myopia (p = 0.25). It has been established that chronic musculoskeletal back pain in young patients is genetically related to the A allele of the vitamin D receptor gene (VDR: 283 (Bsml)) (χ2 = 6.779; p = 0.020; OR = 4.308; 95% CI [1.363; 13.616]).</p></sec><sec><title>Conclusions</title><p>Conclusions. The presence of the A allele of the vitamin D receptor gene (VDR: 283 (Bsml)) in young patients is associated with a genetically determined higher susceptibility to the development of musculoskeletal back pain.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>скелетно-мышечная боль в спине</kwd><kwd>генетические факторы</kwd><kwd>гены коллагена I типа</kwd><kwd>ген рецептора витамина D</kwd></kwd-group><kwd-group xml:lang="en"><kwd>musculoskeletal back pain</kwd><kwd>genetic factors</kwd><kwd>type I collagen genes</kwd><kwd>vitamin D receptor gene</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ravindra V.M., Senglaub S.S., Rattani A., Dewan M.C., Härtl R., Bisson E. et al.
