IMMUNOPATOGENESIS INFEKSI VIRUS DENGUE

Normal 0 false false false EN-US X-NONE X-NONE Dengue , adalah penyakit arboviral tersering yang tersebar di seluruh dunia. Dengue disebabkan oleh infeksi 1 dari 4 serotipe virus dengue. Virus dengue berasal dari keluarga Flaviviridae , genus Flavivirus ( virus RNA ikatan-tunggal tidak ber-segmen).Virus dengue menular ke manusia melalui gigitan nyamuk Aedes betina yang telah ter-infeksi. Virus dengue (DEN) mempunyai 4 serotipe (DEN-1 , DEN-2 , DEN-3 , DEN-4) . infeksi dari salah satu tipe virus bisa tanpa gejala di mayoritas kasus yang terjadi atau bisa menimbulkan gejala klinis. Mulai dari yang ringan dengan gejala seperti flue (yang biasa disebut demam dengue [DF] ) , bentuk yang lebih parah (yang biasa disebut demam berdarah [DHF]) , dan yang hingga menimbulkan gejala syok ( dengue syok sindrom [DSS]). Penyebab dari perkembangan dan mekanisme yang terlibat dalam patofisiologi penyakit infeksi DENV tidak bisa dengan jelas didefinisikan. Immunopatogenesis infeksi virus dengue membahas tentang jalan masuk DENV , aktivasi berlebihan imune yang menyimpang dan menginduksi autoantibody , respon humoral ,peningkatan dependen antibody /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} <![endif]--

ANEMIA SEL SABIT

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Anemia is a form of blood disorder most often occurs in the community. Sickle cell anemia is anemia due to hemoglobinopathy caused by a change in the amino acid-6 of the ? globin chain. Sickle cell anemia is common in tropical areas of Africa and some parts of the region Saudi Arabia, India and the Mediterranean as well as black people in America. In addition there are also careers in various European countries. In pathophysiology, there are amino acid change from glutamic acid to valine in the ?-globin chain that causes red blood cells become sickle-shaped when deoxygenatied, but still be able to return to its normal shape when experiencing oxygenation. When the red blood cell membrane have been amended, the polymerization of red blood cells has become irreversible. Clinical picture seen in sickle cell anemia can be divided into two, namely: acute and chronic. Diagnosis can be done is to distinguish between heterozygous or homozygous sickle cell. Treatment provided in accordance with the clinical picture appears. Treatment that can be done is by blood transfusion, bone marrow transplant, anti-sickling drug delivery, and drug delivery to trigger the synthesis of HbF. Treatment still in the development stage is to use stem cells. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calib
