Patient's question:
Four-year-old girl, previously sick with a blood routine examination, normal white blood cells, but with a low neutrophil count consistently below 20%, lymphocytes always between 70-80%, normal platelets. During upper respiratory infections, her throat was red and swollen, and submandibular lymph nodes were enlarged. Two years ago, she had Mycoplasma infection with a titer of 1:320, which was treated and cured with erythromycin. After the Spring Festival in 2009, she had two upper respiratory infections in succession, less than a week apart, and was treated with cephalosporin and antiviral drugs (intravenous infusion) while also taking oral roxithromycin. During periods of high fever, she was given antipyretics several times. Blood routine examination showed white blood cells below 3, neutrophils 6.6%, lymphocytes 80%, and platelets 85%. Mycoplasma titer 1:320. Mouth ulcers present.Doctor's answer:
Due to the inability to conduct face-to-face consultations with patients and therefore being unable to fully understand the condition, the above suggestions are for reference only. Specific diagnosis and treatment must be carried out at the hospital under the guidance of a doctor!
