"Chronic hepatitis B is still a major health problem in Indonesia. Unfortunately, to date, treatment of chronic HBV (Hepatitis B virus) infection had not shown satisfactory result. Monotherapy with alpha interferon or lamivudine have been widely used as treatment of chronic HBV. However, treatment response to Alpha interferon in Asian people was not satisfactory (15% - 20%), while monotherapy with lamivudine was not sufficient to eradicate HBV in chronically infected patients and commonly induce drug resistance. The occurrence of chronic hepatitis B resistant to lamivudine had encouraged development of newer agents such as adefovir, entecavir, emtricitabine and nucleoside analog. New therapeutic strategy using combination therapy should be considered if there is no sufficient response to monotherapy"

"ABSTRAKMetformin-sulfonilurea dan metformin-akarbose adalah kombinasi terapi yang memiliki mekanisme kerja yang menguntungkan juga diperuntukan dalam pemilihan pengobatan diabetes melitus tipe 2. Review ini bertujuan untuk merangkum perkembangan studi terkini mengenai efektivitas kedua kombinasi obat tersebut. Pencarian literatur artikel penelitian dilakukan secara sistematis dengan melakukan pencarian data melalui Summons Search LIB UI dan didapatkan artikel dari beberapa database yaitu ScienceDirect, ProQuest, Springerlink, dan PubMed. Artikel penelitian yang digunakan dalam review adalah literatur primer yang diterbitkan selama 10 tahun terakhir. Terdapat 6 artikel penelitian yang memenuhi kriteria inklusi. Masing-masing penelitian membahas efek pengobatan dan efektivitas terapi kombinasi dari nilai HbA1c, kejadian hipoglikemia, mean amplitude of glycemic excursions, tingkat stress oksidatif, dan manfaat terapi kombinasi pada risiko kejadian kardiovaskular. Terjadi penurunan nilai HbA1c pada setiap terapi kombinasi dan tidak ada perbedaan nilai yang signifikan pada keduanya, tetapi dari kombinasi metformin-sulfonilurea lebih besar dalam menurunkan nilai HbA1c. Namun, pada terapi kombinasi metformin-akarbose dilaporkan dapat menurunkan nilai dari mean amplitude of glycemic excursions (MAGE), berat badan, dan serum trigliserida, serta terjadi peningkatan serum adiponektin tanpa efek signifikan pada stres oksidatif. Kombinasi metformin-akarbose juga lebih cenderung memiliki manfaat yang lebih baik terutama pada pasien diabetes yang memiliki komplikasi pada kardiovaskular dan tidak meningkatkan risiko terjadinya hipoglikemia.

ABSTRACT

Metformin-sulfonylurea and metformin-acarbose are combination therapy that has a beneficial mechanism action for treating type 2 DM. This review aims to summarize the recent studies regarding the effectiveness of the two drug combinations. The literature search was carried out through Summons Search LIB UI. The research articles used in the review are the primary literature published over the past 10 years. There were 6 research articles that met the inclusion criteria. Each study discussed the effectiveness of combination therapy from HbA1c values, incidence of hypoglycemia, mean amplitude of glycemic excursions, levels of oxidative stress, and benefits of combination therapy on the risk of cardiovascular events. There was a decrease in the value of HbA1c in each combination therapy and there was no significant difference in the value, but the combination of metformin-sulfonylurea was greater in reducing the HbA1c value. However, metformin-acarbose combination therapy was reported to reduce the mean amplitude of glycemic excursions, body weight, and serum triglycerides, as well as increased the serum adiponectin without a significant effect on oxidative stress. The metformin-acarbose combination is more likely to have a better benefit in diabetic patients who have cardiovascular complications and also not increasing the risk of developing hypoglycemia."
