Classical Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency in Croatia between 1995 and 2006
Abstract
Aims: To evaluate the incidence, gender, symptoms and age at diagnosis among patients with classical congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency in Croatia. Methods: Data were collected retrospectively for all classical CAH patients born or electively aborted following prenatal diagnosis between 01.01.1995 and 31.12.2006 and were compared with the data of the previously conducted study evaluating CAH patients discovered between 1964 and 1984. Results: During a 12-year period, 34 classical CAH patients were born. There were 20 salt-wasting (SW) (12 females/8 males) and 14 simple virilizing (SV) patients (7 females/7 males). If 3 female fetuses, electively aborted, were added, that would be a total of 37 CAH patients. With 532,942 live births and 34 CAH patients born over this period, incidence of classical CAH was estimated to 1:15,574 or 1:14,403 if 3 electively aborted fetuses were included. The lower incidence of SW boys compared to SW girls (8:12) and similar number of SW and SV boys (8:7) indicate that substantial proportion of SW boys die unrecognized. Owing to better health care, diagnosis was established significantly earlier in SW and SV girls compared to the period of 1964–1984 (p < 0.003). During 1995–2006, none of the patients died following the diagnosis of CAH, and there was no erroneous sex assignment. Conclusion: Despite of improvement in health care, diagnosis of CAH in Croatia is still delayed and some of the patients go unrecognized or die. Therefore, we think that the results of our study support the need for the introduction of newborn screening.

“Regarding the earlier investigation of the classical form of 21OHD in the Croatian population, one larger population study has been carried out so far, where we reported an incidence of 1:14,403 for classical 21-OHD in the period between 1995 and 2006 (19).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
