[Nephrotic syndrome during pregnancy. Is it chronic glomerulonephritis or preeclampsia? Case report].

Nephrotic syndrome (NS) during pregnancy is a fairly rare pathology and its descriptions in the literature are few. For a long time, NS was associated only with an exacerbation of chronic glomerulonephritis or nephritis, however, the experience of recent years has shown that NS can be a manifestation of the classical obstetric pathology - preeclampsia (PE). The appearance of massive proteinuria with the development of NS is most typical for early PE, which, of course, makes diagnosis difficult, especially if PE develops at an unusually early time (up to 20 weeks).

[Comparative characteristics of the complement system in patients with C3-glomerulopathy and atypical hemolytic uremic syndrome of chronic course who suffered an acute episode of thrombotic microangiopathy].

Aim: To compare changes in the complement system in C3-glomerulopathy (C3-GP) and atypical hemolytic uremic syndrome (aHUS) after the relief of an acute episode of thrombotic microangiopathy.

Materials And Methods: The study included 8 patients diagnosed with C3-GP and 8 with aHUS in remission. The blood levels of the complement system components were determined: C3, C4, C3a, C5a, factor H (CFH), factor B (CFB), membrane-attacking complex (MAC), antibodies to C3b (anti-C3b-AT), the level of hemolytic activity (CH50), the content of factor D (CFD) in the urine.

[Analysis of the course and outcomes of pregnancy in patients with advanced stages chronic kidney disease].

Background: Pregnancy in patients with advanced chronic kidney disease (CKD) is associated with a high risk of adverse outcomes for the mother and the fetus, but data on the characteristics of the course of pregnancy in these women is limited.

Aim: To analyse of the course and outcomes of pregnancy in patients with CKD stages 3a4.

Materials And Methods: Thirty five pregnant women with CKD stages 34 were included: 3a 12 (34.
