Prenatal diagnosis in Italy

Area of Science:

• Medical Genetics
• Obstetrics and Gynecology
• Public Health

Background:

• Italy performs approximately 80,000 prenatal diagnoses (PND) annually, with limited official data on procedure distribution or invasive techniques.
• No national or regional registers exist for PND, particularly for invasive procedures like amniocentesis, chorionic villus sampling, and chordocentesis.
• Congenital malformation data is collected via a regional epidemiological survey system coordinated by the Istituto Superiore di Sanità.

Purpose of the Study:

• To assess the landscape of genetic counseling and prenatal diagnosis services in Italy.
• To identify challenges and areas for improvement in PND services and accessibility.
• To explore current and emerging methods in prenatal diagnosis and their financing.

Main Methods:

• Analysis of data from scientific societies on the distribution of public and private PND structures.
• Review of epidemiological data on congenital malformations (1986-1990).
• Description of current PND methods (echography, amniocentesis, CVS, fetal blood sampling, maternal serum screening) and emerging techniques (amniotic fluid filtration, transcervical cell sampling, fetal cell isolation from maternal blood, 3D sonography).

Main Results:

• Cytogenetic PND indications include advanced maternal age, previous chromosomal anomaly, parental chromosomal abnormality, and abnormal ultrasound findings.
• PND is funded through regional laws, the National Health Service, and private sources.
• Major issues identified are unbalanced regional resource distribution, suboptimal distribution of PND centers, and inadequate prenatal counseling, especially in central/southern Italy.

Conclusions:

• There is a need for established guidelines for appropriate prenatal counseling.
• Advancements in research, such as the Italian National Research Council's 'Genetic Engineering' program, are expected to improve PND cost-effectiveness and detection rates.
• Future efforts should focus on addressing regional disparities and enhancing the quality and accessibility of prenatal diagnosis services.
