Sonographic changes of abdominal organs in children with different course of tuberculosis infection

In order to determine the frequency and nature of sonographic changes in abdominal organs in children with tuberculosis infection, 192 patients at the age of 6 months -14 years were examined on the basis of the tuberculosis department of City Children’s Infectious Hospital №3 for the period 2019-2021. 3 groups of patients were identified: group 1 - 92 children with active respiratory tuberculosis; group 2 – 52 children with residual post-tuberculosis changes; group 3 – 48 children with latent tuberculosis infection at risk of tuberculosis. Sonographic liver changes (reactive and/or intrahepatic cholestasis and/or hepatomegaly) were observed in children with active tuberculosis in 40.2±5.1% of cases, in children of group 3 - in 35.4±6.9% of cases and less often in children of group 2 - in 17.3±5.3% of cases (p<0.05). Changes of the gallbladder (violations of bile outflow and/or shape changes) were visualized in children with active tuberculosis in 73.9±4.6% of cases, in children of group 3 (60.4±7.1% of cases), less often in children of group 2 (55.8±6.7% of cases, p<0.05 for group 1). Changes of the pancreas were reactive and were more often observed in children of group 1 - in 14.1± 3.5% of cases than in children of group 2 (5.8±3.2% of cases, p<0.05) and group 3 (4.2± 2.9% of cases). Also, ultrasound changes of the spleen were more often detected in children with active tuberculosis - in 17.4±4.0% of cases than in children of group 2 (5.8±3.2% of cases, p<0.05) and group 3 (2.1±2.1% of cases, p<0.05).
