. Non-immune hydrops fetalis NIHF is a potentially fatal condition characterized by abnormal fluid accumulation in two or more fetal compartments. Diagnostic criteria are fluid in at. Genetic diseases presenting with hydrops may result from chromosome imbalances or small variations within a single gene. Fetal hydrops is associated with increased perinatal morbidity and mortality.

Genetic Heterogeneity of Hydrops Fetalis In southeast Asia alpha-thalassemia is the most common cause of hydrops fetalis accounting for 60 to 90 of cases. Immune hydrops occurs when the mothers immune system attacks and destroys the babys red blood cells due to incompatible maternal and fetal blood types. The aim of this study was to evaluate the cause evolution and outcome of non-immune fetal hydrops NIFH according to the gestational age at diagnosis. The ultrasonographic incidence of fetal hydrops in referral centers can be as high as one in 165 pregnancies and most cases are of the nonimmune type which can occur in a low-risk population and can be detected with early secondtrimester ultrasound screening.

5 rows Nonimmune hydrops fetalis occurs when a disease or medical condition disrupts the bodys ability. Hydrops fetalis refers to abnormal fluid collections in at least two fetal serous cavities eg ascites pleural effusions andor pericardial effusions often associated with skin edema. Non-immune Hydrops may result from various etiologies including. Hydrops fetalis refers to abnormal fluid collections in at least two fetal serous cavities eg ascites pleural effusions andor pericardial effusions often associated with skin edema.

Non-immune hydrops fetalis NIHF accounts for 90 of all cases and has several etiologies with potentially high perinatal morbidity and mortality depending on the etiology. Hydrops can occur if the developing babys organs cant overcome the anemia. Large amounts of fluid build up in the babys tissues and organs. Thedecision to deliver the infant early must only be undertaken when there is consensus between the obstetrician andthe paediatrician that this is significantly likely to improveoutcome.

Nonimmune hydrops fetalis NIHF comprises the subgroup of cases not caused by red cell alloimmunization eg RhD Kell. Here we report the etiology and outcome of 1004 fetuses with NIHF in a large single Maternal and. Non-immune hydrops fetalis NIHF is a complex condition with a high mortality and morbidity rate. Non-immune hydrops the most common type is caused by a fetal medical condition or birth defect that affects the bodys ability to manage fluid.

Nonimmune hydrops fetalis NIHF comprises the subgroup of cases not caused by red cell alloimmunization eg RhD Kell. Nonimmune hydrops fetalis NIHF a fetal abnormality that is often lethal has numerous genetic causes. Non-immune fetal hydrops is a clinical phenotype and not a diagnosis. Fetal origin eg congenital heart disease premature foramen ovale closure large AV septal defect hematologic erythroblastosis fetalis α-thalassemia due to hemoglobin Barts chronic fetomaternal or twin-twin transfusion infection CMV herpesvirus rubella sepsis toxoplasma pulmonary cystic.

Nonimmune hydrops fetalis NIHF is as pathologic accumulation of fluid in the skin and one or more other body compartments of the fetus including the pleural space peritoneal cavity pericardial sac or placenta. Numerous etiologies may lead to NIHF and the underlying cause often remains unclear 1. In spite of prematurity severe disseminated infection and hydrops the infant survived and was neurologically intact. The hazards of preterm delivery in addition to hydrops should not be taken.

The extent to which exome sequencing can aid in its diagnosis is unclear. Hydrops the degree ofseverity and the like-lihood ofa favourable outcome. This type of hydrops is not common today because Rh negative women are usually treated with Rh immunoglobulin to prevent this problem. The etiology and outcome of fetal hydrops may differ according to the gestational age at diagnosis.

Non-immune hydrops fetalis NIHF refers specifically to cases of hydrops not caused by red cell alloimmunization. Up to 90 of all cases of hydrops today are non-immune hydrops. Hydrops is a symptom of a wide range of conditions which have resulted in an imbalance in fetal fluid between the vascular and interstitial space¹. Non-immune hydrops can develop in pregnancies where the fetus has an underlying genetic disease or when a viral infection occurs.

With the development and widespread use of RhD immune globulin the. Nonimmune hydrops fetalis NIHF historically has been considered a lethal fetal condition. We report a case of non-immune hydrops fetalis NIHF caused by herpes simplex virus type 2 HSV-2 in an infant whose mother had recurrent HSV-2 infection. Nonimmune hydrops fetalis accounts for 76 to 87 of all described cases of hydrops fetalis Bellini et al 2009.

The heart starts to fail. It is associated with a broad spectrum of causes. The identification of hydrops by ultrasound is very frustrating to the family and physicians because it requires extensive search for the etiology which include a wide variety of diseases and pathologies. Understanding NIHF to be a symptom or an end-stage status of a variety of fetal conditions along with improved fetal diagnostics and interventions has changed the landscape for at least some fetuses.

Non-immune hydrops is the presence of two or more abnormal fetal fluid collections in the absence of red cell alloimmunization. Understanding the pathophysiologic mechanisms has led to the development of.
