SLE与慢性活动性肝炎患者免疫状态的观察

作者测定了ＳＬＥ和慢性活动性肝炎的有关免疫学指标，结果：两病Ｉｇ均高于正常对照（Ｐ＜０．００１）；而补体ＣＨ＿（５０）、Ｃ＿３、Ｃ＿４均有不同程度下降，慢活肝Ｃ＿（１ｇ）高于正常人、Ｂ因子低于正常组，ＳＬＥ则相反，Ｃ＿（１ｇ）降低、Ｂ因子升高；两病的ＣＩＣ值均增高，自身抗体ＳＬＥ总检出率为（９６．９７％）并以ＡＮＡ阳性为主（９０．９％）慢活肝总检出率为６８．６％，以ＳＭＡ阳性为主（４８．５７％）。作者认为虽然两病都有相似的免疫学指标，但可以从ＩｇＧ、ＩｇＭ数值，Ｃ＿（１ｇ）、Ｂ因子水平以及ＡＮＡ、ＳＭＡ阳性率等项加以鉴别。

Childhood Henoch-Sch?nlein purpura nephritis and IgA nephropathy: one disease entity?--A clinico-pathologically comparative study.

In order to characterize their relationship through clinicopathological comparison between IgA nephropathy and Henoch-Sch?nlein purpura nephritis (HSPN), 31 children with IgA nephropathy aged between 3 to 15 years and 120 children with HSPN aged between 4 to 15 years were compared with each other in clinical manifestation, blood biochemistry, serum immunology and follow-up study. Renal pathological findings under light microscope, immunofluorescence and electronic microscope were analyzed and also compared between 31 children with IgA nephropathy and 32 biopsied children with HSPN. The results showed that the onset age was over 12 years in 25.8% children with IgA nephropathy, but only 10% in HSPN (P < 0.05). The clinical patterns of IgA nephropathy and HSPN were similar, but extra-renal manifestations were more often in HSPN, all of them had skin purpura, 59% had gastrointestinal symptoms and 47% suffered from arthralgia, compared with only abdominal pain in 3.2% children with IgA nephropathy. The renal pathological investigation showed global sclerosis in 35.5% of IgA nephropathy and 3.1% of HSPN, mesangial sclerosis in 41.9% of IgA nephropathy and 6.3% of HSPN, but endothelial proliferation in 65.6% of HSPN and 29% of IgA nephropathy (all P < 0.01). Thin basement membrane nephropathy was only found in 6.5% children with IgA nephropathy, no in HSPN. The electronic dense deposits in HSPN were sparse, loose and wildly spread in glomerular mesangium, subendothelial area and even intra basement membrane, but it was dense, lumpy and mostly limited in mesangium and paramesangium in IgA nephropathy. Predominant IgA deposits were found in 81.2% of HSPN, and overwhelming IgG deposits in 12.5% of HSPN with relatively weak IgA deposits, moreover 6.3% of HSPN showed linear IgG deposits in glomerular capillary. Totally 71.9% of HSPN had IgG deposits in glomeruli and only 19.4% of IgA nephropathy showed glomerular IgG deposits (P < 0.01). No IgG deposit was observed in 81.6% of IgA nephropathy, among them most showed IgA and IgM and/or C3 deposits, moreover overwhelming IgG deposits and linear IgG deposits couldn't be found in IgA nephropathy. Mean 20 months follow-up showed complete remission in 72.5% of HSPN, but only 19.4% in IgA nephropathy after 34 months follow-up. Moreover, 64.5% of IgA nephropathy had consistent hematuria and proteinuria and 16.1% had active nephritides (P < 0.05). It was concluded that significant clinico-pathological difference was found between HSPN and IgA nephropathy, which didn't support the one disease entity hypothesis. HSPN and IgA nephropathy are probably two diseases with similar immune abnormalities.
