Study Objective To study the effectiveness of complex monitoring of the kidney function, based on biochemical and radionuclide methods in patients with metastatic renal cell carcinoma (mRCC). Materials and Methods 41 mRCC patients after nephrectomy received nivolumab (n = 23) and interferon-α (n = 18) from 2015 to 2017. At baseline and 2 months after, all patients underwent blood chemistry, urinalysis, Rehberg test, and ELISA to determine serum levels of IL-17A, TGF-β, and erythropoietin. The monitoring of the renal function and urodynamics by complex renal scintigraphy (CRS) was used for all patients using a dual-detector gamma camera and simultaneous data recording in 2 projections. The interpretation of CRS data used the original SENS CRS technology. Study Results Statistically significant correlations were established between IL-17A, TGF-β, and D (excretion rate of 99mTc-technephore from the parenchyma) and Rnfsc (a stable sign of nephrosclerosis), respectively. A significant correlation was established between the parameters of the complex functional monitoring with the prognosis for the risk of renal failure (RF) and efficacy of immunotherapy in mRCC. Conclusions All mRCC patients after nephrectomy were recommended to undergo biochemical monitoring with inclusion of TGF-β and IL-17A, as well as radionuclide monitoring (CRS) to determine the RF risk at an early stage.
Рентгенографически показано, что п-ацетиламинобензоаты РЗЭ представляют собой индивидуальные кристаллические вещества. Рассчитаны их межплоскостные расстояния. Методом термографии и термогравиметрии изучена термическая устойчивость полученных соединений. Определены интервалы дегидратации и разложения безводных солей. ИКспектроскопическое исследование позволило предположить преимущественно ионный характер связи в n-ацетиламинобензоатах РЗЭ. Установлено наличие связи металла с карбоксильной группой и отсутствие координации металла с замещенной амино-и амидной группами. Изучена температурная зависимость растворимости всех синтезированных соединений в воде. Ключевые слова: редкоземельные элементы (РЗЭ), соединения РЗЭ, рентгенография, термогравиметрия, кристаллогидраты, растворимость.
