Оценка диагностической точности инфузионной пробы с 3% гипертоническим раствором NaCl по отношению к совокупности клинико-лабораторных данных (включая пробу с депривацией жидкости и данные МРТ) с целью дифференциальной диагностики НД (несахарный диабет) и ПП (первичная полидипсия).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено интервенционное одномоментное исследование на базе ГНЦ РФ ФГБУ «НМИЦ эндокринологии» Минздрава России. В исследование с сентября 2021-го по сентябрь 2023 гг. было включено 90 пациентов с синдромом полиурии-полидипсии. Всем пациентам были последовательно проведены два теста с осмотической стимуляцией: инфузионная проба с 3% гипертоническим раствором NaCl и проба с депривацией жидкости. Оценивались нежелательные явления.</p></sec><sec><title>Результаты</title><p>Результаты. По результатам анализа совокупности клинико-анамнестических, лабораторных и инструментальных данных, результатов пробы с депривацией жидкости 48 пациентам (53%) поставлен заключительный диагноз: «НД», 42 (47%) пациентам — «ПП». Согласованность результатов двух проб является существенной — Каппа = 0,823, 95% ДИ (0,707; 0,939). Операционные характеристики инфузионной пробы с 3% гипертоническим раствором NaCL составили: ДЧ = 98% (95% ДИ: 89–100%), ДС = 98% (95% ДИ: 87–100%), ПЦПР = 98% (95% ДИ: 89–100%), ПЦОР = 98% (95% ДИ: 87–100%).</p><p>Озноб встречался статистически значимо чаще (31 vs. 12%), а выраженность головокружения и головной боли были больше на инфузионной пробе с 3% гипертоническим раствором NaCl. Медиана продолжительности пробы с депривацией жидкости у пациентов составила 11 часов, инфузионной пробы c 3% раствором NaCL — 1,5 часа (Р&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Инфузионная проба с 3% гипертоническим раствором NaCl обладает высокой (98, 95% ДИ (92; 100%)) общей диагностической точностью по отношению к классической совокупности клинико-лабораторно-инструментальных данных пациентов (включающей пробу с депривацией жидкости). Важным преимуществом инфузионной пробы является ее небольшая продолжительность и, как следствие, лучшая переносимость и, вероятно, большая комплаентность, в то время как значимых отличий в возникновении нежелательных явлений при проведении проб выявлено не было.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: assessment of the diagnostic accuracy of a 3% hypertonic saline infusion test in relation to a set of clinical and laboratory data (including a water deprivation test and MRI data) for differential diagnoses of diabetes insipidus (DI) and primary polydipsia (PP).</p></sec><sec><title>METHODS</title><p>METHODS: An interventional cross-sectional study was carried out at Endocrinology Research Centre From September 2021 to September 2023 ninety patients with polyuria-polydipsia syndrome were included. In order to assess the diagnostic characteristics, all the subjects underwent two tests with osmotic stimulation: a 3% hypertonic saline infusion test and a water deprivation test. Adverse events were assessed.</p></sec><sec><title>RESULTS</title><p>RESULTS: Based on the results of clinical, anamnestic, laboratory and instrumental data, and the results of a water deprivation test, a final diagnosis of DI was made in 48 (53%) patients and PP in 42 (47%) patients. The agreement between the two samples is significant — Kappa = 0.823, 95% CI (0.707, 0.939). The operational parameters of the 3% hypertonic saline infusion test are: sensitivity 98% (95% CI: 89%; 100%); specificity 98% (95% CI: 87%; 100%), positive and negative predictive values 98% (95% CI: 89%–100%) and 98% (95% CI: 87%–100%). Respectively. Chills occurred significantly more often (31% vs. 12%), and dizziness and headache were more pronounced during the 3% hypertonic saline infusion test. The median duration of the water deprivation test in patients was 11 hours, and median duration of 3% hypertonic saline infusion test was 1.5 hour (P&lt;0.001).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: The 3% hypertonic saline infusion test has a high overall diagnostic accuracy 98%; 95% CI 92% to 100%)) in relation to the classical set of clinical, laboratory and instrumental data of patients (including a water deprivation test), However, it is important the advantage of the latter is its short duration and, as a consequence, better tolerability and probably better compliance, while no significant differences in adverse events frequencies during the tests were identified.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>проба с сухоедением</kwd><kwd>инфузионная проба с 3% гипертоническим раствором</kwd><kwd>несахарный диабет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the 3% hypertonic saline infusion test</kwd><kwd>water deprivation test</kwd><kwd>diabetes insipidus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках государственного задания № НИОКТР АААА-А17-117012610108-6.</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">Christ-Crain M, Fenske W.
