Структура гомеостатических почечных функций при дисметаболических нефропатиях у детей

Структура гомеостатических почечных функций при дисметаболических нефропатиях у детей

Abstract

THE AIM of the work was to study the indices of water-electrolyte metabolism and stability of urine in children with dismetabolic nephropathies. PATIENTS AND METHODS. The observations were performed in 118 dismetabolic nephropathy children aged from 5 to 16 years. The biochemical methods of the analysis of urine included the following: diurnal urine excretion, urine pH, excretion of ammonia, titrated acidity, concentration and excretion of basic ions (sodium, potassium, inorganic phosphorus, chlorine). Risk of crystallization of urine in relation to the salts of oxalic and uric acids was detected by determining calcium and magnesium ions by the atom-adsorption method. The indices of factors of urine stability and calciphylaxis tests, peroxide and polar lipid tests were studied by standard methods developed by E.Yu.Yurieva (1984). RESULTS. Certain components of the structure of tubular dysfunction were determined in children with dismetabolic nephropathies. CONCLUSION. Changes in indices of the functional state of the kidneys, membrane destruction and urine stability factors were revealed which were better expressed in groups of children with metabolic disorders in combination with inflammatory diseases of the kidneys and non-infectious pathology of organs of the gastro-intestinal tract.

ЦЕЛЬ ИССЛЕДОВАНИЯ. Изучить показатели водно-электролитного обмена и стабильности мочи у детей с дисметаболическими нефропатиями. ПАЦИЕНТЫ И МЕТОДЫ. Под наблюдением находились 118 детей от 5 до 16 лет с дисметаболической нефропатией. Биохимические методы исследования мочи включали: определение суточного диуреза (СД), рН мочи, экскреции аммиака, титруемой кислотности, концентрации и экскреции основных ионов: натрия, калия, неорганического фосфора, хлора. Риск кристаллизации мочи по отношению к солям щавелевой и мочевой кислот выявлялся по определению ионов кальция и магния атомно-адсорбционным методом. Показатели факторов стабильности мочи и тестов на кальцифилаксию, перекиси и полярные липиды проводили с помощью стандартных методик, разработанных Э.Ю.Юрьевой (1984). РЕЗУЛЬТАТЫ. Определены некоторые компоненты структуры канальцевых дисфункций при дисметаболических нефропатиях у детей. ЗАКЛЮЧЕНИЕ. Выявлены изменения показателей функционального состояния почек, мембранной деструкции и факторов стабильности мочи, наиболее выраженные в группах детей с наличием метаболических нарушений в сочетании с воспалительными заболеваниями почек и неинфекционной патологией органов желудочно-кишечного тракта.
