Prospective and parallel assessments of cystic fibrosis newborn screening protocols in the Czech Republic: IRT/DNA/IRT versus IRT/PAP and IRT/PAP/DNA

Abstract: the combined results of the utilized protocols led to the detection of 21 CF patients, 19 of which were identified using the IRT/DNA/IRT protocol, 16 using IRT/PAP, and 15 using IRT/PAP/DNA. Decreased cut-offs for PAP within the IRT/PAP protocol would lead to higher sensitivity but would increase false positives. Within the IRT/PAP/DNA protocol, decreased PAP cut-offs would result in high sensitivity, an acceptable number of false positives, and would reduce the number of DNA analyses. Thus, we concluded that … Show more

“…[100][101][102][103][104][105][106] The combination of IRT/PAP has shown some promise, with sensitivity and specificity reported as similar to that achieved with IRT/DNA but without the unwanted effect of identifying unaffected carriers. [100][101][102][103][104][105][106] The positive predictive value can be improved by employing a multitier approach involving IRT, PAP, and selected, plus expanded, DNA analysis as demonstrated by the CHOPIN study. 107 The approach is yet to gain widespread acceptance but work in this area is ongoing.…”

“…This approach provides easy testing of both samples simultaneously, may save cost, and is less likely to identify unaffected carriers, but conversely also misses milder cases. 26,32 Whichever algorithm is followed, infants with a positive screening result are referred for sweat chloride testing, further clinical evaluation, and additional molecular testing if clinically indicated.…”

“…In Heidelberg wurde das Originalprotokoll zudem derart modifiziert, dass statt 2 IRT-abhän-giger PAP-Grenzwerte nur ein PAP-Grenzwert verwendet wurde [23]. Generelle Vorteile von IRT/PAP-gegenüber IRT/DNA-Protokollen sind die geringere Detektion von gesunden Heterozygoten und von Kindern mit unklarer CF-Diagnose (CFSPID), die nicht Ziel eines CF-NGS sind [9,12,21,22,26]. Nachteil rein biochemischer IRT/PAP-im Vergleich zu IRT/DNA-Protokollen ist jedoch ein schlechterer positiver Vorhersagewert (PPV) [9,12,21,22,26].…”

Nachteil rein biochemischer IRT/PAP-im Vergleich zu IRT/DNA-Protokollen ist jedoch ein schlechterer positiver Vorhersagewert (PPV) [9,12,21,22,26]. 2012 schlug deshalb eine niederländische Arbeitsgruppe vor, das IRT/PAP-Protokoll mit der Suche nach populationsspezifischen CFTR-Mutationen als dritten Schritt zu kombinieren, wodurch der niedrige PPV angehoben werden kann [26].…”
