Question
A four-year-old girl has had normal white blood cell counts in past blood tests, but her neutrophil ratio was below 20%, and her lymphocyte ratio was above 70-80%. Her platelet count was normal. Recently, during a cold, she experienced symptoms such as a sore throat, red and swollen tonsils, and enlarged cervical lymph nodes. Two years ago, she had a mycoplasma infection with a test result of 1:320 and recovered after treatment with rifampicin. After the Spring Festival of 2009, she had two colds in succession, treated with ceftriaxone and antiviral drugs, while taking rifampicin orally. She had a fever and used antipyretics during this period. Her latest blood test showed a white blood cell count below 3, neutrophil ratio dropped to 6.6%, lymphocyte ratio reached 80%, and platelet count was 85. The mycoplasma test was positive again.
Answer
Since a physical examination cannot be conducted, the following suggestions are for reference only and should be followed under a doctor’s guidance. There are many causes of pediatric hematological diseases. If the child is unfortunately diagnosed with pediatric hematological disease, parents should immediately cooperate with the doctor for treatment, including gastrointestinal decompression and maintaining good hygiene habits. Parents should also pay attention to avoiding their child developing picky eating habits and should arrange meals properly.
