104 On admission : the general condition was of moderate severity. The skin and visible mucous membranes were pale, clean, and moist. Physical examination revealed enlarged anterior and posterior cervical lymph nodes: on the left up to 1.5– 2.0 cm in diameter, on the right 2–3 cm in diameter, tender on palpation. Right axillary lymph nodes formed a conglomerate measuring 7×7 cm (individual nodes 1– 2 cm in diameter); left axillary nodes measured 1.5–2.0 cm in diameter. The nodes were tender on palpation, especially on the right, dense-elastic, and mobile. No signs of catarrhal syndrome were present. Nasal breathing was impaired. Tonsils showed grade II hypertrophy, were loose, pink, and without exudates. Over the lungs, percussion revealed clear pulmonary sound; auscultation demonstrated vesicular breath sounds; respiratory rate was 20 breaths/min. Heart sounds were rhythmic and clear; pulse rate was 98 beats/min; blood pressure was 110/60 mmHg; SpO₂ was 98%. The abdomen was soft and non-tender on palpation, with audible bowel sounds. The liver and spleen were not enlarged. There was no peripheral edema, meningeal signs, or neurological symptoms; no focal neurological deficits were detected. Diagnosis on admission: generalized lymphadenopathy syndrome. Tests results: Complete blood count: hemoglobin – 128 g/L, erythrocytes – 4.0 × 10¹²/L, color index – 0.9, hematocrit – 0.41, leukocytes – 2.6 × 10⁹/L, band neutrophils – 22%, segmented neutrophils – 29%, lymphocytes – 33%, monocytes – 7%, eosinophils – 9%, ESR – 15 mm/h, platelets – 183 × 10⁹/L. Biochemical blood test: total protein – 87.8 g/L, urea – 5.0 mmol/L, creatinine – 57.5 μmol/L, total bilirubin – 18.31 μmol/L, direct bilirubin – 6.10 μmol/L, indirect bilirubin – 12.21 μmol/L, serum iron – 4.6 μmol/L, ALT – 35 U/L, AST – 34 U/L. Coagulation profile: prothrombin index – 100%, plasma recalcification time – 80 s, fibrinogen – 355.2 mg/dL, thrombotest – normal. Serological and virological tests: anti-VCA IgG positive, anti-EBNA IgG — 69.58 IU/mL, anti-EA IgG positive, EBV DNA in blood – 4.94 × 10⁵ copies/mL; anti-CMV IgM and anti-CMV IgG – negative; anti-Toxoplasma IgM – negative, anti- Toxoplasma IgG > 8 IU/mL; anti-HIV-1/2 – not detected.
