Women with chronic kidney disease (CKD) have an increased incidence of pregnancy complications, but few comparative studies on features of pregnancy course during chronic glomerulonephritis (CGN) and chronic tubulointerstitial kidney disease (CTID) are available.</p></sec><sec><title>Aim</title><p>Aim: comparison the frequency of pregnancy complications, proteinuria (PU) and serum creatinine dynamics in patients with CGN and CTID.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. We conducted an observational single-centre study enrolling 128 pregnant women with CGN (135 deliveries) and 138 with CTID (145 deliveries) by assessing the incidence of complications, diurnal PU, serum creatinine level starting from early gestation to delivery every 4–6 weeks.</p></sec><sec><title>Results</title><p>Results. Favourable pregnancy outcome was observed in 94.8 % of patients with CGN and in 95.7 % with CTID. The incidence of preeclampsia (PE), placental insufficiency, acute kidney injury, and preterm delivery showed no not inter-group differences, but arterial hypertension, PU &gt; 1.0 g/day were more common in CGN, whereas in CTID – urinary tract infections. During pregnancy, PU increased in both groups, and only in CGN in patients with PE early pregnancy PU was significantly higher than in those without PE. Both groups showed similar serum creatinine dynamics: decrease starting from early pregnancy stages, stabilization in the middle of pregnancy followed by elevation from 28–30 weeks of gestational age until delivery.</p></sec><sec><title>Conclusion</title><p>Conclusion. High PU level in early pregnancy may help to predict PE in CGN, but not in CTID. In patients with CKD, rise in PU along with serum creatinine increased up to baseline level in late pregnancy, are typically observed and without PE, fetal distress should not be considered as unambiguous indication for early delivery.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. У женщин с хронической болезнью почек (ХБП) повышена частота осложнений беременности, однако имеется мало сравнительных исследований особенностей течения беременности у пациенток с хроническим гломерулонефритом (ХГН) и с хроническими тубулоинтерстициальными заболеваниями почек (ХТИЗ).</p></sec><sec><title>Цель</title><p>Цель: сравнение частоты осложнений беременности, а также уровней протеинурии (ПУ) и сывороточного креатинина в разные сроки гестации у пациенток с ХГН и с ХТИЗ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено наблюдательное одноцентровое исследование с участием 128 беременных с ХГН (135 родов) и 138 с ХТИЗ (145 родов). Оценивали частоту осложнений, суточную ПУ и уровень креатинина сыворотки с ранних сроков гестации до родов с интервалами 4–6 недель.</p></sec><sec><title>Результаты</title><p>Результаты. Благоприятный исход беременности наблюдался у 94,8 % пациенток с ХГН и у 95,7 % с ХТИЗ. Частота пре - эклампсии (ПЭ), фетоплацентарной недостаточности, острого повреждения почек, преждевременных родов не различалась между группами; однако при ХГН значимо чаще встречались артериальная гипертензия, суточная ПУ &gt; 1,0 г/сут, а при ХТИЗ – инфекции мочевыводящих путей. В течение беременности ПУ нарастала в обеих группах, при этом только в группе ХГН ПУ в ранние сроки была значимо выше у пациенток с присоединением ПЭ, чем без ПЭ. В обеих группах отмечалась сходная динамика содержания сывороточного креатинина: снижение с ранних сроков, стабилизация в конце II – начале III триместра и последующее нарастание с 28–30 недель до родоразрешения.</p></sec><sec><title>Заключение</title><p>Заключение. Высокая ПУ в ранние сроки беременности может помочь в прогнозировании ПЭ при ХГН, но не при ХТИЗ. У пациенток с ХБП нарастание ПУ, как и рост креатинина сыворотки до исходного уровня в III триместре, характерны и не должны служить однозначным показанием к досрочному родоразрешению при отсутствии диагноза ПЭ и страдания плода.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>хроническая болезнь почек</kwd><kwd>ХБП</kwd><kwd>хронический гломерулонефрит</kwd><kwd>ХГН</kwd><kwd>хронические тубулоинтерстициальные болезни почек</kwd><kwd>ХТИЗ</kwd><kwd>преэклампсия</kwd><kwd>ПЭ</kwd><kwd>протеинурия</kwd><kwd>ПУ</kwd><kwd>креатинин сыворотки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>chronic kidney disease</kwd><kwd>CKD</kwd><kwd>chronic glomerulonephritis</kwd><kwd>CGN</kwd><kwd>chronic tubulointerstitial kidney disease</kwd><kwd>CTID</kwd><kwd>preeclampsia</kwd><kwd>РЕ</kwd><kwd>proteinuria</kwd><kwd>PU</kwd><kwd>serum creatinine</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kovesdy C.P.
