“…Microscopic evaluation showed Marsh 0 histology in 37.5% of patients and Marsh 1 histology in 62.5%. These findings were in line with previous studies [12,[14][15][16][17]: the high rate of first-degree relatives with CD and the high predominance of symptomatic patients could actually explain an increase in serological investigations for CD suspicion and, as consequence, an increase in the prevalence of PCD over time.
