Comparison of age-based clinical and abnormal immune parameters in patients with Henoch-Schönlein purpura / 中华血液学杂志

Objective@#To explore age-based clinical and immune parameters in Henoch-Schönlein purpura (HSP) to determine clinically useful markers reflecting disease characteristic.@*Methods@#A cohort of 502 patients with HSP were enrolled into this retrospective study to evaluate their clinical and immune data.@*Results@#Majority HSP cases occurred at age ≤14 years and showed significant immune imbalances of ESR, CD3+ cells, CD4+ cells, CD3-CD16+CD56+ cells, CD4+/CD8+ cells, IgG, IgA, IgM, IgE, complements C3/C4 and ASO in the acute phase. Compared to patients aged >14 years, symptoms of joint were more frequent at disease onset in patients aged ≤14 years (20.8% vs 7.6%, χ2=13.547, P<0.001) , and involvement of digestive tract and joint were also more frequent (57.4% vs 33.8%, χ2=24.106, P<0.001; 55.9% vs 32.5%, χ2=23.768, P<0.001, respectively) , but not for involvement of kidney (21.4% vs 51.3%, χ2=42.440, P<0.001) . The patients aged ≤14 years had distinct immune state, reductions of CD3+ cells, CD4+ cells and IgG were more frequent than patients aged >14 years, also increase of ASO (33.1% vs 20.0%, χ2=6.656, P=0.010) , but not increase of IgA (2.6% vs 39.4%, χ2=15.582, P<0.001) . In addition, reduction of IgG and increase of IgE were positively associated with digestive tract involvement (P<0.001, P=0.001, respectively) , reduction of CD3+CD4+ cells and normal IgM were positively associated with joint involvement (P=0.004, P=0.003, respectively) , increase of CD3+CD8+ cells and normal CD3+ cells were positively associated with kidney involvement (P=0.032, P=0.014, respectively) .@*Conclusion@#HSP showed significant immune imbalance in the acute phase, patients between aged ≤14 and >14 years had distinct clinical and immune characteristic, and abnormal immune parameters were significantly associated with organ involvements.

The relationship between serum CXC chemokine ligand-10 level and Graves' disease / 中华内分泌代谢杂志

The serum level of CXCL10 was determined in both patients with Graves' disease (GD) and normal control subjects.Serum CXCL10 levels in untreated and relapsed GD groups were higher compared with the remission group and control group( P＜0.01 ).A significant difference was observed between the former two GD groups (P＜0.01 ),but no difference was found between latter two groups( P＞0.05 ).Serum CXCL10 levels were positively correlated with FT3 and FT4,and negatively correlated with TSH by multiple linear regression analysis( P＜0.01 ).
