DefinisiApakah Diabetes itu ??

DEFINISI :

Kumpulan gejala penyakit yang timbul pada seseorang yang disebabkan oleh peningkatan kadar gula darah akibat penurunan sekresi insulin yang disebabkan oleh kerusakan sel beta pancreas dan resistensi insulin ( PERKENI)

– Apabila hormon insulin yang dihasilkan oleh sel beta pankreas tidak mencukupi untuk merubah glukose menjadi energi, maka glukose akan tetap dalam darah dan kadarnya akan meningkat

Klasifikasi Diabetes Mellitus Berdasarkan Etiologinya American Diabetes Association ( ADA, 2003)

1. Diabetes Mellitus Tipe 1:Destruksi sel β umumnya menjurus ke arah defisiensi insulin absolut, melalui proses imunologik (Otoimunologik) dan Idiopatik

2.Diabetes Mellitus Tipe 2Bervariasi, mulai yang predominan resistensi insulin disertai defisiensi insulin relatif sampai yang predominan gangguan sekresi insulin bersama resistensi insulin

3. Diabetes Mellitus GestasionalDiabetes mellitus yang muncul pada masa kehamilan, disebabkan oleh hormon yang disekresikan plasenta yang akan menghambat kerja insulin, umumnya bersifatsementara, tetapi merupakan faktor risiko untuk DM Tipe 2

4. Diabetes Mellitus Tipe Lain-Defek genetik fungsi sel β-Penyakit pankreas-Autoimun

5. Gangguan Toleransi GlukosaA. IFG (Impaired Fasting Glucose) = GPT (Glukosa Puasa Terganggu)B. IGT (Impaired Glucose Tolerance) = TGT (Toleransi Glukosa terganggu)

Generasi 2

DIABETES MELLITUS TIPE 1 : - Jarang / populasinya sedikit (5-10 % dari penderita

diabetes mellitus)

- Gangguan produksi insulin pada DM Tipe 1 umumnya terjadi karena kerusakan sel-sel β pulau Langerhans yang disebabkan oleh reaksi otoimun, virus, dsb

- Destruksi otoimun dari sel-sel β pulau Langerhans kelenjar langsung mengakibatkan defisiensi sekresi insulin.

DIABETES MELLITUS TIPE 2

- sangat umum terjadi

- populasinya 90 – 95 % penderita Diabetes Mellitus

- Etiologinya belum terungkap dengan jelas, kebanyakan karena pola hidup, faktor genetik dan pengaruh lingkungan.

- sel-sel sasaran insulin gagal atau tak mampu merespon insulin secara normal. Keadaan ini lazim disebut sebagai “Resistensi Insulin”.

Diabetes gestasional

Diabetes pada kehamilan- Diabetes / intoleransi glukosa yang terjadi pada masa

kehamilan- Umumnya timbul pada atau setelah trimester ke 2- Sekitar 4-5 % wanita hamil menderita DM- Berlansung sementara dan dapat pulih setelah

kehamilan

Akibat DM gestasional•Malformasi kongenital•Berat badan bayi berlebih•Resiko mortalitas perinatal

Perbedaan dm TIPE 1 DAN DM TIPE 2

Mula muncul Umumnya masa kanakkanakdan remaja,walaupun ada juga padamasa dewasa < 40 tahun

Pada usia tua, umumnya> 40 tahun

Mechanism of Insulin Action• Insulin binds to specific high

affinity membrane receptors with tyrosine kinase activity

• Phosphorylation cascade results in translocation of Glut-4 (and some Glut-1) transport proteins into the plasma membrane.

• It induces the transcription of several genes resulting in increased glucose catabolism and inhibits the transcription of genes involved in gluconeogenesis.

• Insulin promotes the uptake of K+into cells.

Insulin: Actions• Increases glucose uptake in to cells• Increases glycolysis• Increases glycogen synthesis• Reduces glycogen breakdown• Reduces gluconeogenesis

• Reduces lipolysis• Increases fatty acid synthesis• Increases cholesterol & LDL synthesis

• Increases amino acid transport• Increases protein synthesis• Reduces protein breakdown• K+ uptake into cell

α-GLUCOSIDASE INHIBITORS

e.g. Acarbose

PHARMACOKINETICS

Given orally

Not absorbed from intestine except small amount

t1/2 3 - 7 hr

Excreted with stool

α-Glucosidase InhibitorsThis enzyme hydrolyses

oligosaccharides to monosaccharides which are then absorbed. Acarbose also inhibits pancreatic amylase. The normal post-prandial glucose rise is blunted, glucose levels rise modestly and remain slightly elevated for a prolonged period, less of an insulin response is required and hypoglycemia is avoided; use with other agents may result in hypoglycemia. Sucrase is also inhibited by these drugs.

54

MECHANISM OF ACTION

Inhibits intestinal alpha-glucosidases and delays carbohydrate absorption, reducing postprandial increase in blood glucose

INDICATIONS

Type II diabetes alone or in combination with

metformin or sulfonylurea or insulin in patients resistant to insulin treatment.

THIAZOLIDINEDIONE DERIVATIVES(Contd.)

Thiazolidinediones

• Counteract insulin resistance

• Bind to PPAR-gamma (receptor), forming a complex promoting transcription of genes sensitive to insulin.

• Receptors are present in skeletal muscle, adipose tissue &liver, thereby promoting uptake of fatty acids &glucose at these sites

Insulin Sensitizers

Two classes of oral hypoglycemics work by improving insulin target cell response; the biguanides and thiazolidinediones.

Biguanides:• Metformin is classified as an insulin sensitizer, it increases

glucose uptake and utilization by target tissues. It requires the presence of insulin to be effective but does not promote insulin secretion. The risk of hypoglycemia is greatly reduced.

Thiazolidinediones• These agents are insulin sensitizers, they do not promote

insulin secretion from β-cells but insulin is necessary for them to be effective. Pioglitazone and rosigglitazone are the two agents of this group.

Insulin SensitizersThiazolidinediones

(Glitazones)• These agents are

insulin sensitizers, they do not promote insulin secretion from β-cells but insulin is necessary for them to be effective. Pioglitazone and rosigglitazone are the two agents of this group.
