To study rate of detection of bacteria and viruses from dif ferent ta xonomic groups and their associations in children with pyelonephritis. Materials and methods . Two hundred seventy-four patients aged 5 — 10 years divided on two groups were studied: 1 st group — 240 children with chronic secondary pyelonephritis, 2 n d group — children with nephrectomy due to terminal stage of renal obstructive process. Qualitative and quantitative composition of bacterial flora in urine and renal biopsy samples was studied by bacteriological methods as well as presence of viruses (HSVI, HSVII, CMV, EBV, HPV) by means of PCR. Results . In group 1, 72.2% of children had bacterial mixed infection with associations of coagulase-negative staphylococci, Escherichia , peptococci, and Mycoplasma . Herpesviruses and human papillomaviruses were detected in 50.0% of cases. In group 2, bacterial flora was isolated from preoperative urine in diagnostically-significant titer in 91.2% of cases, whereas in urine obtained from the same patients during operation the microorganisms were detected in 38.2% of cases with predominance of Mycoplasma and Ureaplasma . Bacteriological tests of renal biopsy samples yielded bacteria in 29.5% of cases. Studied viruses were detected in preoperative and intraoperative urine as well as in renal biopsy samples in 52.9%, 44.1%, and 58.8% of cases, respectively. In 32.4% of patients viruses were detected in biopsy samples but not in intraoperative renal pelvis’ urine. There was no difference in HPV and CMV detection rate in the nephrectomy group. Conclusion . Bacterial-viral mixed infection is encountered in children with obstructive pyelonephritis and this should be taken into account during diagnostics and treatment of this condition.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучение частоты встречаемости бактерий и вирусов различных таксономических групп и их ассоциаций при пиелонефрите у детей. Материалы и методы. Обследованы 274 пациента в возрасте 5 — 10 лет, подразделенные на 2 группы: 1 группа — 240 детей с хроническим вторичным пиелонефритом; 2 группа — дети, которым была произведена нефрэктомия в терминальной стадии обструктивного процесса в почке. Изучен количественный и качественный состав бактериальной флоры мочи и биоптатов почек и наличие вирусов (HSV I, HSV II, CMV, EBV, HPV) методом ПЦР. Результаты. У детей 1 группы в 72,2% случаев регистрировали бактериальную микст-инфекцию, ассоциированную с коагулазоотрицательными стафилококками, эшерихиями, пептококками и микоплазмами. Герпетические и папилломные вирусы обнаруживаются у 50,0% больных. У 2 группы больных с нефрэктомией до операции бактериальная флора в диагностически значимом титре обнаружена в 91,2% случаев, из интраоперационной порции мочи у тех же больных — в 38,2% случаев с доминированием микоплазм, уреаплазм. При бактериологическом исследовании биоптатов почек бактерии обнаружены в 29,5% случаев. Изучаемые вирусы регистрировали в моче до нефрэктомии в 52,9%, в интраоперационной — в 44,1%, в биоптатах почек — в 58,8% случаев. У 32,4% больных вирусы обнаруживали в биоптатах при отсутствии их в лоханочной моче. Различий в частоте обнаружения HPV и CMV при нефрэктомии практически не было. Заключение. При обструктивном пиелонефрите у детей регистрируется бактериально-вирусная микст-инфекция, что необходимо учитывать при диагностике и лечении данной патологии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bacterial-viral infection</kwd><kwd>detection rate</kwd><kwd>obstructive pyelonephritis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бактериально-вирусная инфекция</kwd><kwd>частота встречаемости</kwd><kwd>обструктивный пиелонефрит</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Анохин В.А., Бондаренко В.М., Поздеев О.К. и др.
