[The diagnosis and dispensary care of pregnant patients with nephropathy].

365 females followed up for 4-6 years who had new-onset or repeated nephropathy at pregnancy (NP) showed during the II and III trimester impaired humoral immunity evident from elevated levels of IgA, IgM and CIC. NP relapses at repeated pregnancies occurred in 89%, residual manifestations of the disease in 45% of the examinees. Postnatal immunological studies of women with previous NP but no clinical signs of it at the time of examination still continued to demonstrate alterations in cellular and humoral immunity. Glomerular filtration rate in response to water loading indicated their reduced renal reserves. It is suggested that in nonpregnant females with an NP history this disease runs a subclinical course which may be considered a remission. This dictates certain diagnostic and therapeutic measures that should be taken to prevent complications. NP patients follow-up and regular check-ups help to decrease relevant risk at subsequent pregnancies.
