【流感知識】

流感嗜血桿菌是一種沒有運(yùn)動力的革蘭氏陰性桿菌。它是于1892年由費(fèi)佛博士在流行性感冒的瘟疫中發(fā)現(xiàn)。它一般都是好氧生物，但可以成長為兼性厭氧生物。
流感嗜血桿菌zui初被誤認(rèn)為是流行性感冒的病因，但直至1933年，當(dāng)發(fā)現(xiàn)流行性感冒的病毒性病原后，才消除了這種誤解。不過，流感嗜血桿菌仍會導(dǎo)致其他不同種類的病癥。

有證據(jù) 提示本病存在免疫調(diào)節(jié)異常。本病的含IgA1循環(huán)免疫復(fù)合物中， 發(fā)現(xiàn)有多聚的IgA1類風(fēng)濕因子；抗α重鏈Fab片斷的IgG抗體增多 而IgM抗體減少。有趣的是HIV感染者也存在類似的抗免疫球蛋白 模式，卻不發(fā)生腎臟IgA沉積。這證明單單這些循環(huán)的自身抗體存 在，并不是系膜IgA沉積的原因。此外目前還發(fā)現(xiàn)了二種抗內(nèi)皮細(xì) 胞的自身抗體（屬IgG）。本病腎組織中常有C3沉積，提示激活了 補(bǔ)體旁路途徑。然而IgA本身無激活補(bǔ)體的能力，IgA免疫復(fù)合物 雖可激活補(bǔ)體旁路途徑，但它結(jié)合補(bǔ)體和C3b的能力很弱。通常認(rèn) 為在腎臟發(fā)生補(bǔ)體激活和形成膜攻擊復(fù)合物，需有IgG-IgA復(fù)合物 ，但是本病腎組織中有IgA和C3沉積而沒有IgG或IgM沉積卻很常見 。因此，本病補(bǔ)體激活的機(jī)制尚不清楚。細(xì)胞免疫也參與了發(fā)病 機(jī)制。已發(fā)現(xiàn)本病可有T輔助細(xì)胞（CD4）增加和T抑制細(xì)胞（CD8 ）減少；具有轉(zhuǎn)換IgM合成為IgA合成的Ta4細(xì)胞增加，與之有關(guān)的 Sa1等位基因的頻度也增加；引起IgA同型轉(zhuǎn)換的TGFβ、促進(jìn)產(chǎn)生 IgA的B淋巴細(xì)胞分化的IL-5和介導(dǎo)IgA產(chǎn)生的IL-4形成均有增加 。雖然T細(xì)胞和B細(xì)胞均參與了增加IgA合成的過程，但I(xiàn)gA合成增 多并不是系膜區(qū)IgA沉積的原因，因?yàn)樵贗gA多發(fā)性骨髓瘤病人中 罕見有組織IgA沉積。因此，結(jié)構(gòu)-免疫學(xué)/理化異常才可能是系膜 IgA沉積的原因。
Evidence suggests that there is an immunoregulatory abnormality in this disease. Among the IgA1 circulating immune complexes of this disease, polyvalent IgA1 rheumatoid factor was found; the IgG antibody against the α heavy chain Fab fragment increased while the IgM antibody decreased. Interestingly, HIV-infected persons also have similar anti-immunoglobulin patterns but no renal IgA deposition. This proves that these circulating autoantibodies alone are not responsible for the deposition of mesangial IgA. In addition, two anti-endothelial autoantibodies (genus IgG) have been discovered. C3 deposition often occurs in the renal tissue of this disease, suggesting activation of the complement alternative pathway. However, IgA itself has no ability to activate complement. IgA immune complexes can activate the complement alternative pathway, but its ability to bind complement and C3b is weak. It is generally believed that IgG-IgA complexes are required for complement activation and membrane attack complexes in the kidney, but it is common for the disease to have IgA and C3 deposition but no IgG or IgM deposition. Therefore, the mechanism of complement activation in this disease is not yet clear. Cellular immunity also participates in the pathogenesis. It has been found that the disease may have increased T-helper (CD4) and T-suppressor (CD8) cells; the number of Ta4 cells synthesized by converting IgM synthesis to IgA increases, and the frequency of Sa1 alleles associated therewith also increases; causing IgA Isotype-transformed TGFβ, IL-5 that promotes IgA-producing B lymphocyte differentiation, and IL-4 formation that mediates IgA production are all increased. Although both T and B cells are involved in the process of increasing IgA synthesis, increased IgA synthesis is not responsible for IgA deposition in the mesangial area because of the rare tissue IgA deposition in IgA patients with multiple myeloma. Therefore, structural-immunological/physicochemical abnormalities may be responsible for the deposition of mesangial IgA.
