Fakta tentang Penyakit Autoimmune (AI)
Etiologi belum diketahui dengan pasti Banyak menyerang wanita muda. Gambaran klinik beberapa penyakit AI juga mirip penyakit Non AI, terutama pada fase dini. Antara satu penyakit AI dengan yg lain juga kadang2 sulit membedakan. Angka kematian cukup tinggi. Pengobatan belum memberi hasil yg memuaskan Efek samping pengobatan

The immune system The immune system is a network of organs,
cells and molecules that work together to defend the body against attacks by foreign (not of the body) invaders such as germs, bacteria, viruses, parasites and fungi. We will focus on adaptive responses. All these feature of an adaptive response require very specific interactions of molecules. Will describe B and T cells and their roles. Immunological memory - vaccination
5
The immune system Anatomic barriers (Skin,mucous membranes)
Innate (non-specific) immunity Adaptive (specific) immunity Anatomic barriers (Skin,mucous membranes) Physological barriers (temperature, pH) Phagocytic Barriers (cells that eat invaders) Inflammatory barriers (redness, swelling, heat and pain) Antigen specificity Diversity Immunological memory Self/nonself recognition We will focus on adaptive responses. All these feature of an adaptive response require very specific interactions of molecules. Will describe B and T cells and their roles. Immunological memory - vaccination
6
Autotolerance Unresponsiveness to self antigens is known
as autotolerance Both B-cells and T-cells participate in tolerence but T-cells play the primary role Yamamoto K. JMAJ 2004; 47(9): 403–406.
7
Clinical Importance of Tolerance
1) Organ transplantation: Introduction of tolerance may help in prevention of rejection 2) Tumor development: Tolerance to tumor antigen results in growth of the tumor without being detected by the immune mechanisms 3) Autoimmune disorders: Disturbance of self-tolerance results in autoimmune disease

The Spectrum of Autoimmune disease
Organ specific Hashimoto Thyroiditis Primary myxedema Thyrotoxicosis Pernicious Anemia Autoimmune atrophic gastritis Addison’s disease Premature menopause (certain cases) Male infertility (certain cases) Myasthenia gravis IDDM Goodpasture’s syndrome Pemphigus vulgaris Pemphigoid Sympathetic ophtalmia Phacogenic uveitis (Multiple sclerosis) AIHA ITP Idiopathic leucopenia Primary billiaris cirhosis Active chronic hepatitis HBs-ve Ulcerative colitis Sjogren syndrome Rheumatoid arthritis Scleroderma Wegener’s granulomatpsis Poly/dermatomyositis Discoid lupus erythematosus Systemic lupus erythematosus (SLE) The Spectrum of Autoimmune disease The spectrum of autoimmune diseases is very wide. We can find one with very organ specific involvement such as can be seen in Thyroiditis of Hashimoto to the very bizarre and dynamic clinical manifestation in Lupus. There are some factors plays an important role in their pathogenesis and will involved many actors in immune systems. To date we still do not understand why the same actors will lead to a specific autoimmune disease and the others will have a overlapped syndromes. Non-organ specific Kelly et al, Text book of Rheumatology, 2005

Patogenesis Penyakit Autoimun
12
Type-III Hypersensitivity: Immune Complex
Animation: Large quantities of soluble antigen-antibody complexes form in the blood and are not completely removed by macrophages. These antigen-antibody complexes lodge in the capillaries between the endothelial cells and the basement membrane. The antigen-antibody complexes activate the classical complement pathway and complement proteins and antigen-antibody complexes attract leukocytes to the area. The leukocytes then discharge their killing agents and promote massive inflammation. This leads to tissue death and hemorrhage

Prinsip pengobatan penyakit AI
Menekan aktifitas sistim imun Menggunakan steroid dan obat imunosupressan Mencari keseimbangan antara efikasi dari obat2an dan efek samping pengobatan yang mungkin timbul Mengobati komorbiditas Tindakan non farmakologis
28
Obat-obatan imunosupressan
Steroid Klorokuin/hidroksiklorokuin Methotrexate (MTX) Azathioprine (Imuran) Siklosporin (Sandimun) Cyclophosphamide Cellcept/Myfortic IV IG Biologic agents
29
Kesimpulan Penyakit AI adalah kondisi dimana sistim imun tidak mengenali dirinya sendiri dan membentuk berbagai macam sel dan autoantibodi yang menyerang berbagai macam organ. Etiologi belum diketahui dengan pasti. Ada dua sel yang sangat berperan didalam patogenesis penyakit AI yaitu sel B dan sel T. Proses kejadian AI, dimulai dengan terbentuknya autoantigen, yang kemudian dipresentasikan oleh sel APC ke sel T, selanjutnya sel T mengaktifkan sel B, yang selanjutnya membentuk autoantibodi. Bertemunya autoantigen dan autoantibodi merupakan awal dari terjadinya kerusakan orga. Pengobatan belum memberi hasil yang memuaskan, beberapa obat yang sering digunakan adalah steroid, Imuran, sandimun, MTX, hydroxyclorokuin, siklofosfamid, cellcept, dan myfortic. Myfortic memiliki efektifitas di banding cellcept dan efek samping yg minimal.
