Evidence from the studies in adult patients has been summarized in systematic reviews and meta-analyses. The results of the studies in adolescents remain poorly systematized.</p> <p><bold>AIM:</bold> To summarize the findings from the studies that investigated the relationship of IHRs with mental disorders in adolescent patients.</p> <p><bold>METHODS:</bold> This scoping review included studies of IHRs in patients aged 10–19 years with mental disorders (other than anorexia nervosa), published in English by December 31, 2023. The search for relevant papers was performed in MEDLINE. The studies were categorized into two groups: studies with external controls (healthy adolescents) and studies with internal controls (patients in different phases of mental disorder, with or without self-harm/suicidal behaviors).</p> <p><bold>RESULTS:</bold> A total of 11 studies were included in the review (all cross-sectional ones). The results of these studies demonstrate that 1) adolescents with mental disorders (major depressive disorder, psychotic disorders, obsessive-compulsive disorder, attention deficit hyperactivity disorder, substance use disorders) have higher IHR values than individuals of the same age without corresponding disorders (5 studies); 2) IHR values are positively correlated with the severity of psychopathological symptoms (1 study); 3) higher IHR values are associated with the phase of the mental disorder — manic episode in bipolar disorder (1 study) and exacerbation of psychosis in psychotic disorders (1 study); and 4) higher IHR values are associated with self-harm/suicidal behaviors — suicide attempts (1 study) and non-suicidal self-injury (1 study).</p> <p><bold>CONCLUSION:</bold> IHRs are associated with mental disorders in adolescents, and higher IHR values are associated with a more severe/acute clinical presentation (severity of symptoms, mania, acute psychosis, self-harm/suicidal behaviors). Further studies of higher methodological quality are needed to evaluate the diagnostic and prognostic value of IHRs as biomarkers of mental disorders in adolescence.</p></abstract><trans-abstract xml:lang="ru"><p><bold>ВВЕДЕНИЕ:</bold> Гематологические коэффициенты воспаления (ГКВ), такие как нейтрофильно-лимфоцитарное, моноцитарно-лимфоцитарное, тромбоцитарно-лимфоцитарное отношение, ассоциированы с психическими расстройствами, их тяжестью, фазой заболевания. Данные, полученные у взрослых пациентов, обобщены в систематических обзорах и метаанализах. Результаты подобных исследований у подростков не систематизированы.</p> <p><bold>ЦЕЛЬ:</bold> Обобщить результаты исследований, в которых изучали связь ГКВ с психическими расстройствами у пациентов подросткового возраста.</p> <p><bold>МЕТОДЫ:</bold> В обзор предметного поля включали исследования ГКВ у пациентов в возрасте 10–19 лет с психическими расстройствами (кроме нервной анорексии), результаты которых опубликованы на английском языке до 31 декабря 2023 года. Поиск потенциально релевантных работ проводили в базе данных MEDLINE. Отобранные работы анализировали, разделив их на 2 группы: исследования с внешним контролем (здоровые подростки) и исследования с внутренним контролем (пациенты с разной фазой психического расстройства, наличием/отсутствием аутоагрессивного поведения).</p> <p><bold>РЕЗУЛЬТАТЫ:</bold> В обзор включены результаты 11 кросс-секционных исследований. Анализ их результатов показал: 1) у подростков с психическими расстройствами (депрессия, психотические расстройства, обсессивно-компульсивное расстройство, синдром дефицита внимания и гиперактивности, расстройства, связанные с употреблением психоактивных веществ) значения ГКВ выше, чем у их сверстников без соответствующих расстройств (5 исследований); 2) значения ГКВ положительно коррелируют с выраженностью психопатологических симптомов (1 исследование); 3) высокие значения ГКВ связаны с фазой психического расстройства — манией при биполярном аффективном расстройстве (1 исследование) и обострением психоза при психотических расстройствах (1 исследование); 4) высокие значения ГКВ связаны с аутоагрессивным поведением — суицидными попытками (1 исследование) и несуицидальными самоповреждениями (1 исследование).</p> <p><bold>ЗАКЛЮЧЕНИЕ:</bold> ГКВ связаны с психическими расстройствами у подростков, их тяжестью/остротой (выраженностью симптомов, фазой заболевания, наличием аутоагрессии). Для оценки диагностической и прогностической ценности ГКВ в качестве биомаркеров психических расстройств в подростковом возрасте необходимы дальнейшие исследования более высокого методологического качества.</p></trans-abstract><kwd-group xml:lang="en"><kwd>inflammatory hematological ratios</kwd><kwd>systemic inflammation</kwd><kwd>mental disorders</kwd><kwd>adolescents</kwd><kwd>biomarkers</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гематологические коэффициенты воспаления</kwd><kwd>системное воспаление</kwd><kwd>психические расстройства</kwd><kwd>подростки</kwd><kwd>биомаркеры</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Minihane AM, Vinoy S, Russell WR, et al.
