“…Fetal hydrops is associated with a high risk of intrauterine death unless a treatable cause is identified 13,18,19 and left ventricular function are also bad prognostic signs, 19 but the impact of having at least one of these risk factors, including early gestational age at time of diagnosis, has, to the best of our knowledge, not been studied before.…”

Background-Isolated complete atrioventricular block in the fetus is a rare but potentially lethal condition in which the effect of steroid treatment on outcome is unclear. The objective of this work was to study risk factors associated with death and the influence of steroid treatment on outcome. Methods and Results-We studied 175 fetuses diagnosed with second-or third-degree atrioventricular block (2000 -2007) retrospectively in a multinational, multicenter setting. In 80% of 162 pregnancies with documented antibody status, atrioventricular block was associated with maternal anti-Ro/SSA antibodies. Sixty-seven cases (38%) were treated with fluorinated corticosteroids for a median of 10 weeks (1-21 weeks). Ninety-one percent were alive at birth, and survival in the neonatal period was 93%, similar in steroid-treated and untreated fetuses, regardless of degree of block and/or presence of anti-Ro/SSA. Variables associated with death were gestational age Ͻ20 weeks, ventricular rate Յ50 bpm, fetal hydrops, and impaired left ventricular function at diagnosis. The presence of Ն1 of these variables was associated with a 10-fold increase in mortality before birth and a 6-fold increase in the neonatal period independently of treatment. Except for a lower gestational age at diagnosis in treated than untreated (23.4Ϯ2.9 versus 24.9Ϯ4.9 weeks; Pϭ0.02), risk factors were distributed equally between treatment groups. Two-thirds of survivors had a pacemaker by 1 year of age; 8 children developed cardiomyopathy. Conclusions-Risk factors associated with a poor outcome were gestation Ͻ20 weeks, ventricular rate Յ50 bpm, hydrops, and impaired left ventricular function. No significant effect of treatment with fluorinated corticosteroids was seen. (Circulation.

“…However, in pregnant women with a confirmed primary infection, the overall risk of an abnormal outcome is approximately 5 to 10% (91,261,270). Nonimmune hydrops fetalis is rare (1 in 3,000), and in 20 to 50% of cases the etiology is unknown (148,354). Meta-analysis has shown that B19 accounts for 15 to 20% of cases of nonimmune hydrops fetalis, with a mean interval between the onset of maternal infection and fetal symptoms of 6 weeks (367).…”

Parvovirus B19 (B19) was discovered in 1974 and is the only member of the family Parvoviridae known to be pathogenic in humans. Despite the inability to propagate the virus in cell cultures, much has been learned about the pathophysiology of this virus, including the identification of the cellular receptor (P antigen), and the control of the virus by the immune system. B19 is widespread, and manifestations of infection vary with the immunologic and hematologic status of the host. In healthy immunocompetent individuals B19 is the cause of erythema infectiosum and, particularly in adults, acute symmetric polyarthropathy. Due to the tropism of B19 to erythroid progenitor cells, infection in individuals with an underlying hemolytic disorder causes transient aplastic crisis. In the immunocompromised host persistent B19 infection is manifested as pure red cell aplasia and chronic anemia. Likewise, the immature immune response of the fetus may render it susceptible to infection, leading to fetal death in utero, hydrops fetalis, or development of congenital anemia. B19 has also been suggested as the causative agent in a variety of clinical syndromes, but given the common nature, causality is often difficult to infer. Diagnosis is primarily based on detection of specific antibodies by enzyme-linked immunosorbent assay or detection of viral DNA by dot blot hybridization or PCR. Treatment of persistent infection with immunoglobulin reduces the viral load and results in a marked resolution of anemia. Vaccine phase I trials show promising results

ResumoOBJETIVO: Identificar a etiologia da hidropisia fetal não imune em gestantes diagnosticadas e encaminhadas para acompanhamento pré-natal. MÉTODOS: Estudo retrospectivo com análise dos casos de hidropisia fetal não imune que foram acompanhados entre março de 1992 e dezembro de 2011. Os casos tiveram confirmação diagnóstica pela presença de edema de subcutâneo fetal (≥5 mm) com derrame em pelo menos uma cavidade serosa por meio da ultrassonografia obstétrica, e a investigação etiológica foi realizada com pesquisa citogenética (cariótipo), infecciosa (sífilis, parvovírus B19, toxoplasmose, rubéola, citomegalovírus, adenovírus e herpes simples), hematológica e metabólica (erros inatos), além de com ecocardiografia fetal. Foram excluídas as gestações gemelares. A análise estatística foi efetuada pelo teste do χ 2 para aderência (software R 2.11.1). RESULTADOS: Foram incluídas 116 pacientes com hidropisia fetal não imune, sendo que 91 casos (78,5%) tiveram a etiologia elucidada e 25 casos (21,5%) foram classificados como causa idiopática. A etiologia cromossômica foi a que apresentou maior número de casos, totalizando 26 (22,4%), seguida da etiologia linfática com 15 casos (12,9%, sendo 11 casos de higroma cístico), da etiologia cardiovascular e da infecciosa com 14 casos cada (12,1%). Os demais casos tiveram etiologia torácica em 6,9% (oito casos), síndromes malformativas em 4,3% (cinco casos), tumores extratorácicos em 3,4% (quatro casos), metabólica em 1,7% (dois casos), hematológica, gastrintestinal e geniturinária em 0,9% cada (um caso cada). No período pós-natal, foram seguidos 104 casos por até 40 dias de vida, 12 casos tiveram morte fetal intrauterina. A sobrevida desses 104 recém-nascidos foi de 23,1% (24 sobreviveram). CONCLUSÃO: a etiologia da hidropisia diagnosticada na gestação deve tentar ser esclarecida, uma vez que está associada a um amplo espectro de doenças. É especialmente importante para determinar se uma condição potencialmente tratável está presente e para identificar doenças com risco de recorrência em futuras gestações para aconselhamento pré-concepcional adequado. Abstract PURPOSE:To identify the etiology of nonimmune hydrops fetalis cases in pregnant women diagnosed and referred for prenatal care. METHODS: Retrospective analysis of cases with nonimmune hydrops fetalis that were monitored between March 1992 and December 2011. Diagnosis was confirmed by the presence of fetal subcutaneous edema (≥5 mm) with effusion in at least one serous cavity using obstetric ultrasound, and etiological investigation was conducted with cytogenetic (karyotype), infectious (syphilis, parvovirus B19, toxoplasmosis, rubella, cytomegalovirus, adenovirus and herpes simplex), hematologic and metabolic (inborn errors) analysis and fetal echocardiography. Twin pregnancies were excluded. Statistical analysis was performed using the χ 2 test for adhesion (software R 2.11.1). RESULTS: We included 116 patients with nonimmune hydrops fetalis; the etiology was elucidated in 91 cases (78.5%), while 25 cases (21.5%) wer...
