ABSTRACT
The aim of study was to assess the diagnostic value of ultrasound diagnostics of chronic lymphoproliferative syndrome in the young children. 88 children aged 2–3 years with pathology of the lymphadenoid ring of the pharynx, accompanied by regional cervical lymphadenitis, needing surgery were examined. Endoscopy of the nasopharynx, otomicroscopy, impedance, ultrasound examination of cervical and submandibular lymph nodes, abdominal organs, complete blood count with a manual differential, ELISA to determine specific IgM, IgG to cytomegalovirus (CMV) antigens, to human herpes virus type 6 (HCV-6) antigens, to nuclear, viral capsid and early antigens complex Epstein – Barr virus (EBV), PCR in scrapes from the oropharyngeal mucosa and blood were performed. The patients were divided into two groups: group I with pronounced lymphadenopathy (lymph nodes conglomerates 31×13 mm in size or multiple) (n = 32), group II with moderate lymphadenopathy (single symmetrical painless lymph nodes less than 16 mm in size) (n = 56). In the group I, the following were statistically significant more frequent: snore and sleep apnea (Fisher's exact test, p < 0,001, odds ratio (OR) 13,00, 95% confidence interval (CI) 4,439–38,07); manifestations of asthenic vegetative and intoxication syndromes (p < 0,001, OR 7,80, CI 2,248–27,06); ultrasound signs of hepatic splenic syndrome (p < 0,001, OR 34,71, CI 7,185–167,7); serological markers of contamination and active stages EBV infection (p < 0,001, OR 16,71, CI 4,673–55,27); markers of mixt EBV + CMV + HHV-6 infections (p < 0,001, OR 16,20, CI 3,327–78,87), compared to the group II. Regional cervical lymphadenitis with lymph nodes diameter more than 16 mm on ultrasound was a sign of pronounced chronic lymphoproliferative syndrome in the young children, in which half were found to have markers of the EBV infection active stage. The development of pronounced cervical lymphadenitis is associated with hepatic splenic syndrome, usually caused by the herpesvirus infections reactivation.
