ABSTRACT
<p><b>OBJECTIVE</b>To provide an objective reference for the syndrome types of Chinese medicine (CM) associated with pediatric primary nephrotic syndrome (PNS).</p><p><b>METHODS</b>A cross-sectional study was performed. Data on clinical symptoms, CM syndrome types, biochemical indices, and medications used were collected from 98 children with PNS. Then, the correlation between CM syndromes and biochemical indices, as well as medications used, was analyzed.</p><p><b>RESULTS</b>The four most common symptoms in children with PNS were brown urine, red tongue, excessive sweating, and swelling of the face and limbs. The syndromes of qi deficiency of Fei (Lung) and Shen (Kidney) (FSQD) and yin deficiency of Gan (Liver) and Shen (GSYD) were the most common main CM syndrome types. FSQD syndrome score correlated significantly with the total cholesterol level, urine protein/creatinine ratio, and urine IgG and albumin levels (P<0.01 or P<0.05). The use of maintenance glucocorticoids combined with immunosuppressive agents correlated with FSQD syndrome, and the use of maintenance glucocorticoids alone correlated with GSYD syndrome (P<0.05).</p><p><b>CONCLUSION</b>Two of the most common CM syndrome types were FSQD and GSYD syndromes. FSQD syndrome may be caused by some factors related to lipid levels, protein loss, and the use of immunosuppressive agents. The use of maintenance glucocorticoids may cause GSYD syndrome.</p>
