Aims: Evaluation of lactase activity in biopsy samples of mucous membrane of small intestine (MMSI) in children with coeliac disease (CD). Methods: 50 children with CD aged 1 to 17 years (medium age 8.8�?±0.7 years). Patients were randomized to three groups: First-18 (36.0%) patients with acute CD; second-23 (46.0%) children on a strict gluten-free diet (age 5.6�?±0.8 years); third-9 (18.0%) patients not on a diet (age 3.9�?±0.9 years). Results: In acute CD hypolactasia (HL) occurred in 14 (77.8%) patients, of whom in 10 (55.6%) cases it was severe HL and in 4 (22.2%) cases moderate HL. Correlation analysis showed a negative correlation between lactase activity and anti-tTG level IgA (r=-0.23, p<0.05) and anti-tTG level IgG (r=-0.22, p<0.05). Th e negative correlation between EMA titer (IgA, IgG) and lactase activity (r=-0.46, p<0.02) was observed. Atrophy of Marsh 2 type occurred in 1 (2.0%) child, Marsh 3A type in 12 (24.0%) children, Marsh 3Ð�? type in 21 (42.0%) children and Marsh 3C type in 16 (32.0%) children. In patients with severe HL total MMSI atrophy equivalent to Marsh 3С was 1.8 times higher than in children with moderate HL (p<0.05) and 5.8 times higher than in patients with normolactasia (NL) (p<0.01). When on gluten-free diet the rate of severe and moderate HL was 9 (39.1%) and 8 (34.8%), and in patients not on a diet 4 (44.4%) and 3 (33.3%) cases, respectively (p>0.05). Conclusions: Th e maximal level of MMSI atrophy (Marsh 3C) was observed in 47.8% patients with severe HL. Autoimmune antibody titer (EMA, anti-tTG) positively correlate with HL severity in children with CD.
