Villitis is characterized by the inflammation Figure 13.1 A term placenta, bread-loafed to show extensive perivillous fibrin deposition, which was histologically found to be associated with VUE. Microscopic We examined placentas where villitis was diagnosed in a previous pregnancy to establish the risk of recurrence and outcome. A total of 304 cases of VUA were Chronic villitis is found in 5-15% of placentae and pregnancies complicated by fetal growth restriction and intrauterine death have an increased incidence, up to 34 villitis and maturation disorders.

2020-06-01 2017-01-01 Placental villitis, which is defined by the presence of lymphocytic or macrophagic inflammatory cells within the villosities, constitutes a recently-described histopathological entity. This condition is the consequence of an immune response of the feto-placental unit towards a non-specific, multiple aggression and the incidence is very low. Chronic villitis is a relatively common pathologic finding usually in the third trimester placenta and has two distinct clinical associations: infectious and (apparently) non‐infectious. Villitis of unknown etiology (VUE) is a diagnosis of exclusion, requiring first that infectious causes be ruled out adequately 1 , 4 - 11 .

outcome. In a few recent cohort studies, the placentas of pregnant women infected with SARS-CoV-2 have shown higher rates of maternal or fetal vascular malperfusion features associated with adverse outcomes (5, 6). We report herein a case of chronic villitis in the placenta of a pregnancy complicated by COVID-19. We hypothesize that

Results . 29 patients had influenza infection. Placentas of 15 of these patients were collected and examined. CIP and in particular chronic villitis may be caused directly by some viral infections, such as cytomegalovirus. 10 There is a case report of histiocytic intervillositis, another form of CIP with a high rate of adverse outcomes, in a second trimester miscarriage due to COVID-19.

Villitis was found in 12 SGA‐placentas (7.5 per cent) and 8 AGA placentas (2.8 per cent) (p < 0.05). The degree of villitis was also related to growth retardation (p < 0.05). Except for one placenta with villitis due to CMV infection, the cause of villitis could not be determined.

Placental involvement by CMV infection has been typically made by histological diagnosis of focal segmental lymphoplasmacytic villitis [28, 29], with additional histological features as described above and depicted in Fig. 1, and confirmed by positive immunohistochemistry or in situ hybridization on placental tissue [4, 5, 6, 17] (Figs. 1 and 2).

When low-grade 2021-04-01 · Chronic villitis of unknown etiology (VUE) is a chronic inflammatory lesion of third trimester placenta, which contributes to major adverse obstetric outcomes. However, the inciting factors and mechanisms by which VUE contributes to adverse outcomes are poorly understood. A study by Mortimer et al. of 120 consecutive placentas found 10 with villitis, of which six cases had fetal growth restriction, with 5 showing moderate and one mild villitis 2. In another study confirming a correlation of villitis with IUGR, the authors noted a significant association of villitis with normal ponderal index and speculated that this implied an early onset of the factors causing Placental chronic villitis was observed in 44 cases (2.12%) of 2,073 histologically examined placentas. Infiltrating lymphocytes in chronic villitis were determined by immunohistochemistry to be predominantly helper/inducer T cells. The topic Nonspecific Chronic Villitis of Placenta you are seeking is a synonym, or alternative name, or is closely related to the medical condition Villitis of Unknown Etiology.

Placentitis is an inflammation of the placenta.The main forms of placentitis are: Villitis, inflammation of chorionic villi.; Intervillositis, inflammation of the intervillous space.; It may be caused by vertically transmitted infections..
