Lacrimal insufficiency was found in 49% of patients. It occurred more frequently (χ2=9.546; p=0.003) in patients taking amantadine and correlated with the daily dose of amantadine (r-S=-0.359). It did not depend on the intake of ADR and levodopa and their doses but correlated with the UPDRS-IV score (r-S= -0.463), namely with the presence and duration of OFF-periods. Lacrimal insufficiency correlated with the Sch&amp;En score (r-S=0.321) and non-motor parameters: UPDRSI (r-S =-0.302), NMSQ (r-S=-0.435), constipation domain of the GSRS (r-S=-0.362), BSFS (r-S=0.363). It was not related to age, gender, stage and duration of PD, motor symptoms of parkinsonism (assessed during the ON-phase) and was not related to salivation (although it was reduced in 39.5% of patients).</p></sec><sec><title>Conclusion</title><p>Conclusion. Lacrimal insufficiency is observed in half of patients with stage II–III PD; it is related to the presence and duration of OFF-periods, the severity of other autonomic disorders and the use of amantadines, suggesting the role of dopamine dysregulation, neurodegeneration of autonomic centers and anticholinergic therapy in the development of DES in PD.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Распространенность синдрома сухого глаза (ССГ) при болезни Паркинсона (БП) достигает 87% и приводит к снижению качества жизни многих пациентов.</p><p>Цель исследования – оценить функцию слезоотделения и влияние на нее дофаминергической терапии у пациентов с БП.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование вошли 43 пациента с БП II–III стадии по Хену и Яру, получающие терапию леводопой (n=17), амантадинами (n=13), агонистами дофаминовых рецепторов (АДР; n=28), они были обследованы с использованием теста Ширмера для измерения количества слезы, Унифицированной рейтинговой шкалы болезни Паркинсона (Unified Parkinson's Disease Rating Scale, UPDRSI-IV), Шкалы повседневной активности Шваба и Ингланда (Schwab and England Activities of Daily Living, Sch&amp;En), суммарного индекса Опросника качества жизни при болезни Паркинсона (the Parkinson’s Disease Questionnaire Summary Index, PDQ-39 SI), Краткой шкалы оценки психического статуса (Mini Mental State Examination, MMSE), Опросника немоторных симптомов (Non-Motor Symptom Questionnaire, NMSQ), Шкалы Американской урологической ассоциации (The American Urological Association symptoms Scale, AUA), Шкалы оценки желудочно-кишечных симптомов (Gastrointestinal Symptom Rating Scale, GSRS), Бристольской шкалы (Bristol Stool Form Scale, BSFS); также измеряли количество слюны.</p></sec><sec><title>Результаты</title><p>Результаты. Недостаточность слезоотделения выявлена у 49% пациентов. Она встречалась чаще (χ2=9,546; р=0,003) у лиц, принимающих амантадин, и коррелировала с суточной дозой амантадина (rS=-0,359), не зависела от факта приема АДР и леводопы и их дозы, но коррелировала с оценкой по UPDRS-IV (r-S=-0,463), а именно – с наличием и длительностью периодов выключения. Недостаточность слезоотделения коррелировала с оценкой по Sch&amp;En (r-S=0,321) и немоторными показателями: UPDRSI (r-S=-0,302), NMSQ (r-S=-0,435), доменом «запоры» GSRS (r-S=-0,362), Бристольской шкалой (r-S=0,363). Она не зависела от возраста, пола, стадии и длительности БП, моторных симптомов паркинсонизма (оценивались в период включения), не связана с слюноотделением (хотя последнее было снижено у 39,5% пациентов).</p></sec><sec><title>Заключение</title><p>Заключение. У половины пациентов с БП II–III стадии наблюдается недостаточность слезоотделения, которая связана с наличием и длительностью периодов выключения, тяжестью других вегетативных расстройств и приемом амантадинов, что свидетельствует о роли дофаминовой дизрегуляции, нейродегенерации вегетативных центров и холинолитической терапии в формировании ССГ при БП.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>немоторные нарушения</kwd><kwd>вегетативные нарушения</kwd><kwd>слезоотделение</kwd><kwd>желудочно-кишечная дисфункция</kwd><kwd>амантадин</kwd><kwd>леводопа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Parkinson's disease</kwd><kwd>non-motor disorders</kwd><kwd>autonomic dysfunction</kwd><kwd>lacrimation</kwd><kwd>gastrointestinal dysfunction</kwd><kwd>amantadine</kwd><kwd>levodopa</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chrysou A, Jansonius NM, van Laar T.
