ABSTRACT
Objective To analyze serum levels of C1q in children with nephrotic syndrome (NS),and investigate the clinical significance and the relationship among the altered serum C1q levels and other lipid/lipoprotein and renal function parametersin children with NS inacute and remission phases.Methods Serum levels of C1q were measured in 78 NS children with acute phase,in 64NS children with remission and in 77 healthy control children.The other lipid/lipoprotein and renal function parameters were also analyzed in these children,including TP,ALB,TC,TG,LDL-C,HDL-C,Urea,Cr and Uric.Results Compared with the healthy control children [173.00(161.00～185.00)mg/L],children with NS inacute [203.50(183.75 ～ 223.75) mg/L] and remission phases [185.00 (161.00 ～ 202.00) mg/L] all had a significantly increasedserum levels of C1q.Compared with NS children in remission,those in acute phase showed a significantly increased C1q (P＜0.001).In all the NS children,the serum levels of C1q were positively correlated with the levels of TC (r=0.483,P＜0.001),TG (r=0.423,P＜0.001) and LDL-C (r=0.450,P＜0.001),while negatively correlated with the levels of TP (r=-0.276,P=0.001 ＜0.01) and ALB (r=-0.410,P＜0.001).Multiple linear regression analyses showed that serum levels of C1q were independently associated with serum TG levels (β=9.235,P＜0.001;adjusted R2 =0.215) after adjustment of other related factors.Conclusion Serum levels of C1q were significantly increased in NS children in association with their conditions and the levels of lipid/lipoprotein parameters,and may be function as anovel parameter for assessing the development of NS.
ABSTRACT
Objective The systemic inflammatory response syndrome ( SIRS) can be caused by infection and non-infection factors, which have similar clinical features but differ in treatment and prognosis .Rapid synthesis of procalcitonin ( PCT) during infec-tion can be used as a biomarker for the early diagnosis of sepsis .The present study aims to assess the value of the serum PCT level in the etiological diagnosis and prognosis of SIRS in the surgical ICU . Methods We retrospectively analyzed the data on 166 cases of SIRS from the surgical ICU in Jinling Hospital between June 2014 and June 2015 .The data obtained were associated with the patients'demograph-ics, primary diseases, laboratory results, and clinical outcomes.We analyzed the serum PCT values , blood culture results , and clinical outcomes. Results Totally, 131 of the patients were diagnosed with sepsis, with a median value of serum PCT of 2.43 (0.81-10.51) ng/mL, of whom 109 were PCT-positive (≥0.47 ng/mL), with a positive rate of 83.2%.Among the 35 non-infection SIRS patients, the mean level of serum PCT was 0.23 (0.1 -0.39) ng/mL, with a positive rate of 17.14%(6/35).There were statistically significant differences between the two groups in both the ser-um PCT level and positive rate (P<0.05).The PCT-positive rate was significantly higher in the bacteria-infected than in the fungi-in-fected group (86.5%[83/96] vs 74.3%[26/35], P<0.05), with a median value of 4.28 (1.05-14.59) ng/mL and 0.89 (0.37-1.59) ng/mL, respectively, so was it in the survivors than in the non-survivors (94.4%[34/36] vs 78.9%[75/95], P<0.05), with a median value of 12.89 (4.76-47.73) ng/mL and 1.41 (0.54-4.00) ng/mL, respectively. Conclusion The se-rum PCT level might be used to distinguish between sepsis and non-infection SIRS, significantly higher in bacteria-infected and survival groups than in fungi-infected and non-survival groups .Serum PCT determination contributes to the etiological diagnosis and prognosis of SIRS.
