Abstract:
Objective To explore the clinical characteristics and correlation of adult primary nephrotic syndrome (PNS) with thyroid dysfunction,and early identify high-risk adult PNS patients with abnormal thyroid function by clinical data.Methods The clinical data of 101 adult PNS patients in Heji Hospital Affiliated to Changzhi Medical College from March 2015 to December 2017 were retrospectively analyzed.According to the thyroid function,the patients were divided into 2 groups:normal thyroid function group (67 cases) and thyroid dysfunction group (34 cases),including 9 cases with low triiodothyronine (T3) syndrome and 25 cases with subclinical hypothyroidism.The clinical data were compared,and the correlation between thyroid-stimulating hormone (TSH) and 24 h urinary protein,blood albumin and systolic blood pressure were analyzed.Results The incidence of thyroid dysfunction in adult PNS patients was 33.66％ (34/101),including 21 cases of membranous nephropathy,8 cases of minimal change disease,4 cases of IgA nephropathy and 1 case of membranoproliferative nephritis.The 24 h urinary protein in thyroid dysfunction group was significantly higher than that in normal thyroid function group:(8.76 ± 3.62) g vs.(6.96 ± 3.43) g,the albumin was significantly lower than that in normal thyroid function group:(21.82 ± 4.89) g/L vs.(24.49 ± 4.14) g/L,and there were statistical differences (P＜0.05 or ＜0.01);there was no significant difference in gender composition,age,course of disease,systolic blood pressure,diastolic blood pressure,body mass index,hemoglobin,platelet,creatinine,cystatin C,fasting blood glucose,total cholesterol,triacylglycerol,low-density lipoprotein cholesterol (LDL-C),fibrinogen,complement C3,IgG,IgM,IgA,PNS types and comorbidities between 2 groups (P＞0.05).The results of subgroup analysis results showed that the systolic blood pressure in subclinical hypothyroidism patients of thyroid dysfunction group was significantly higher than that in normal thyroid function group and the low T3 syndrome patients of thyroid dysfunction group:(148.16 ± 18.09) mmHg (1 mmHg =0.133 kPa) vs.(139.55 ± 18.77) and (127.78 ± 16.81) mmHg,the 24 h urinary protein was significantly higher than that in normal thyroid function group:(9.00 ± 3.64) g vs.(6.96 ± 3.43) g,the albumin was significantly lower than that in normal thyroid function group:(21.71 ± 5.26) g/L vs.(24.49 ± 4.14) g/L,and there were statistical differences (P＜0.05).Pearson correlation analysis result showed that TSH had no correlation with 24 h urinary protein and systolic blood pressure (r =0.193 and 0.072,P =0.053 and 0.472);however TSH was negatively correlated with albumin (r =-0.340,P =0.001).Conelusions In adult PNS patients with thyroid dysfunction,membranous nephropathy is the most common,followed by minimal change disease.The systolic blood pressure in PNS patients with subclinical hypothyroidism is significantly higher than that in patients with normal thyroid function and low T3 syndrome.In adult PNS patients,the lower the blood albumin is,the more likely they have thyroid dysfunction.
