Diabetes mellitus merupakan penyakit degeneratif yang memerlukan pengobatan yang intensif. Tanaman tradisional untuk pengobatan diabetes banyak dijumpai di masyarakat dan telah digunakan secara turun temurun. Pugun Tana (Picria felterrae Lour.) merupakan tumbuhan khas yang digunakan oleh masyarakat Dairi untuk pengobatan diabetes. Data hasil penelitian efektifitas sebagai antidiabetes dari Pugun Tana belum banyak dilakukan. Penelitian ini dilakukan bertujuan untuk menguji keamanan dan efektifitas dari Pugun Tanan sebagai antidiabetes sehingga dapat digunakan sebagai tanaman tradisional yang aman dan berkhasiat.Penelitian ini dilakukan dengan karakteristik simplisia daun (penentuan kadar air, penentuan kadar abu total dan tidak larut dalam asam, penentuan kadar sari larut etanol dan penentuan larutan kadar sari larut air). Ekstrak dibuat dalam crude extract dengan metode maserasi-perkolasi.Uji Toksisitas secara akut crude extract daun pugun tana tidak menunjukkan tanda-tanda keracunan dan kematian yang berarti sampai dosis 10.000 mg/kg bb. Crude extract pugun tana (Picria felterrae Lour.) dikategorikan praktis tidak toksis atau toksisitas ringan. Namun, data indeks organ menunjukkan bahwa ada perbedaan dari organ seperti hati, dan perbedaan ini tidak memberikan perbedaan yang berarti dibandingkan dengan dosis lainnya. Uji Toleransi glukosa dengan pemberian larutan glukosa dosis 5 g/kg bb menunjukkan bahwa pemberian ekstrak etanol pugun tana dosis 50, 100 dan 200 mg/kg BB tersebut menurunkan kadar gula darah tikus yang diberikan glukosa 50%. Suspensi ekstrak pugun tana dosis 100 mg/kg bb memberikan penurunan kadar gula darah hampir sama dengan suspensi glibenklamid dosis 10 mg/kg bb dan kenaikan dosis ekstrak tidak memberikan efek penurunan kadar gula darah yang lebih baik. Kata kunci: tikus obesitas, toleransi glukosa, toksisitas akut, picria felterrae, pugun tana

Chemerin is adipokine that plays an important role in macrophage infiltration into adipose tissue and may contribute to inflammation development and insulin resistance. This study aimed to determine the effect of lifestyle modification with and without metformin on chemerin in metabolic syndrome. Forty-five metabolic syndrome subjects (IDF-2005) were randomly assigned to one of the two groups: placebo group (n=22) and metformin group (n=23). Both groups underwent a 12-week lifestyle modification (diet and moderate aerobic-exercise). Only 40 participants (placebo group n=20 and metformin group n=20) completed the survey whereas 5 participants dropped out of the study. After their lifestyle was modified, body weight, BMI, WC, and chemerin decreased significantly (p<0.001) in both groups. Moreover, there was a significant difference between both groups in body weight, BMI, and WC (p<0.05) but not for chemerin. Thus, lifestyle modification with metformin improved BW, BMI, WC on metabolic syndrome, and there was no decrease significantly of chemerin between placebo and metformin groups. Further investigations should be done to confirm the effect of lifestyle modification and metformin on chemerin after an extended follow-up period.

Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxideproduction and involved in various pathological processes, especially processes involvingcardiovascular risk. The purpose of this study was to analyze the correlation betweenADMA and anthropometric, glucose, lipid, and inflammatory parameters. The study wasanalyzed by a cross-sectional study of 45 obese subjects at H. Adam Malik Hospital. Bloodtests were carried out after 8-10 hours of fasting against cardiovascular risk: anthropometry(body weight, BMI, and WC), glucose (FPS, PPS, HbA1C, Fasting Insulin, and HOMA-IR), lipid (LDL-C, HDL-C, TG, and sd-LDL), and inflammation (ApoB and hs-CRP)parameters. The results showed of the 45 subjects, the average age was 41.69 ± 5.69 yearsold, and the average BMI was 33.09 ± 5.05 (Obesity I). ADMA was also found to becorrelated significantly with FPG, HBA1c, and TG parameters [r=-0.506, p=0.001; r=-0.334, p=0.013, dan r = -0.315. p=0.017, respectively]. In obesity, ADMA correlatedsignificantly with cardiovascular risk parameters: FPG, HbA1C, and TG.

Fetuin-A is a liver-synthesized protein that is secreted into serum. Transforming growth factor-β (TGF-β) is a polypeptide member of the TGF-β superfamily of cytokines. The purpose of this study is to evaluate the effects of lifestyle modification and metformin on fetuin-A and Transforming Growth Factor-ß (TGF- ß) in metabolic syndrome (MetS). Forty MetS subjects were randomly assigned to treatment with placebo (n=20) or metformin (n=20) in addition to lifestyle modification for 12 weeks. All 40 participants completed the study. After 12 weeks, both groups had significant reductions in weight, body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP) (all p<0.001). The placebo group also had significant improvement in fasting plasma glucose (FPG) and C-reactive protein (CRP) (p<0,001 ; p<0.05 respectively). Weight, BMI, WC, FPG, 2-hour postprandial glucose (2h-PPG), high density lipoprotein cholesterol (HDL-C), triglycerides (TG), fetuin-A and TGF- ß in the metformin group decreased significantly compared to the placebo group. Reduction of plasma fetuin-A was significantly associated with TG in the metformin group. Lifestyle modification and treatment with metformin for 12 weeks improved cardio-metabolic risk factors in MetS and reduced fetuin-A levels.

Apolipoprotein B (ApoB) levels reflect the total number potentially atherogenic particles that can predict cardiovascular risk. The purpose of this study was to assess if the ApoB in obese subjects is associated with inflammatory markers. This cross-sectional study was conducted on 80 obese patients at H. Adam Malik Hospital, Medan, Indonesia. Results: Of the 80 patients studied, the average age was 38.95 + 8.13 years old. There was a strong positive correlation between ApoB and triglycerides (r=0.44, p<0.001), low-density lipoprotein cholesterol (r=0.74, p<0.001), and HOMA-IR (r=0.31, p=0.005), however not with the inflammatory markers; adiponectin (r=-0.23, p=0.41) and Chemerin (r=0.021, p=0.851). In obesity, ApoB significantly associated with lipid and insulin resistance, as a risk factor for cardiovascular disease.

Resistensi Insulin (IR) mungkin merupakan faktor kunci potensial di balik derajat keparahan COVID-19 namun di Indonesia sendiri, belum ada data mengenai hubungan resistensi insulin terhadap derajat keparahan COVID-19, khususnya yang menggunakan pemeriksaan HOMA IR. Untuk mengetahui hubungan resistensi insulin dengan derajat keparahan COVID-19 pada pasien Diabetes Melitus tipe 2. Penelitian ini dengan rancangan analitik cross sectional dengan pengambilan data secara prospektif dengan sumber rekam medis yang di rawat inap isolasi RSUP Haji Adam Malik Medan dari bulan Juni 2021 – September 2021 pada pasien yang terdiagnosa COVID-19 dengan komorbid diabetes mellitus yang memenuhi kriteria inklusi dan eksklusi. Untuk analisis resistensi insulin berdasarkan skor HOMA-IR dengan derajat keparahan COVID-19 berdasarkan manifestasi klinis yang muncul (ringan, sedang, berat, dan kritis) dilakukan uji chi square dan dinyatakan bermakna apabila nilai p 0.05. Mayoritas subjek penelitian memiliki skor HOMA-IR 3,8 sebanyak 35 orang, 21 orang (60,0%) di antaranya merupakan COVID-19 derajat berat dan 8 orang (22,9%) di antaranya merupakan COVID-19 derajat sedang, 6 orang (17,1%) di antaranya merupakan COVID-19 derajat kritis. Subjek penelitian yang memiliki skor HOMA-IR 2,6 sebanyak 32 orang, 24 orang (75,0%) di antaranya merupakan COVID-19 derajat sedang, 7 orang (21,9%) di antaranya merupakan COVID-19 derajat berat dan 1 orang (3,1%) di antaranya merupakan COVID-19 derajat kritis. Subjek penelitian yang memiliki skor HOMA-IR 2,6-3,8 sebanyak 7 orang, 4 orang (57,1%) diantaranya merupakan COVID-19 derajat sedang, 2 orang (28,6%) di antaranya merupakan COVID-19 derajat berat dan 1 orang (14,3%) di antaranya merupakan COVID-19 derajat kritis. Terdapat perbedaan yang signifikan antara skor HOMA-IR dengan derajat keparahan COVID-19 secara statistik.
