It was found that ischemic stroke (IS) results in decreased levels of a number of reduced forms of low molecular weight aminothiols (LMWTs). The study was aimed to assess the impact of type 2 diabetes mellitus (Т2D) on the total content, reduced forms and redox status of LMWTs in patients with IS. A total of 175 patients with IS in the internal carotid artery basin (the average age was 62 (55–69)) years) were assessed, who were admitted to the Center within the first 10–24 h since the onset of neurological disorder. The index group included 68 patients with IS and T2D (males made up 41.2%). The comparison group consisted of 107 patients with IS and stress hyperglycemia (males made up 57%), and the control group included 31 non-diabetic patients with chronic cerebrovascular disease (CCVD) (males made up 54.8%). The admission plasma levels of LMWTs were assessed by liquid chromatography in all patients. It was found, that IS in patients with T2D was associated with the rapid decrease in total cysteine (tCys), total glutathione (tGSH), total homocysteine (tHcy), reduced glutathione (rGSH), and glutathione redox status (GSH RS), along with the increase in cysteine redox status (Cys RS) and homocysteine redox status (Hcy RS). In contrast to patients with stress hyperglycemia developing during the acute period of IS, patients with T2D had lower tCys, tGSH, and tHcy levels. Thus, GSH RS of 4.06% or lower in the first 24 hours after the IS in patients with T2D was a predictor of poor functional outcome (mRS score was 3 or more 3 weeks after IS).

Ischemic stroke (IS) and type 2 diabetes mellitus are factors that affect the homeostasis of low-molecularweight aminothiols (cysteine, homocysteine, glutathione etc.). It has already been shown that IS in the acute period led to a decrease a level of reduced forms of aminothiols, but it is not clear whether type 2 diabetes mellitus has a noticeable effect there. Objective: to reveal the features of homeostasis of aminothiols in patients with type 2 diabetes mellitus in acute IS. Material and methods. The study involved 76 patients with primary middle cerebral artery IS in the first 10–24 hours after development of neurological symptoms. Group 1 included 15 patients with IS and type 2 diabetes mellitus, group 2 — 61 patients with IS and stress hyperglycemia. Their total plasma levels of cysteine, homocysteine, and glutathione, their reduced forms, and redox status were determined at admission (in the first 24 hours after IS). Results. There was a decrease in the level of total glutathione level (1.27 vs. 1.65 μM, p = 0.021), as well as its reduced form (0.03 vs. 0.04 μM, p = 0.007) in patients with IS and type 2 diabetes mellitus. Patients with type 2 diabetes mellitus who had a low redox status of homocysteine (0.65–1.2%) and glutathione (0.7–2.0%) were also characterized by a decrease in total glutathione level (p = 0.02; p = 0.03). Conclusion. Thus, type 2 diabetes mellitus is associated with a decrease in the level of total glutathione in acute IS. Probably, type 2 diabetes mellitus is characterized by a particular relationship between the metabolism of homocysteine, glutathione and glucose. Therefore, the search for homocysteine-dependent approaches to correct glutathione metabolism in type 2 diabetes mellitus may be of interest as an adjuvant therapy for IS.

BACKGROUND :Ischemic stroke is the most common stroke comprising 70-80% of all cases. Carotid intima-media thickness (CIMT) is associated with the occurrence of stroke in older age and adults. Patients with type 2 diabetes mellitus tend to develop a thickening of intima-media carotid artery. Simvastatins inhibit further atherothrombotic process. OBJECTIVE : To analyze the effect of simvastatin for CIMT in ischemic stroke patient with type 2 diabetes mellitus. METHOD : This study was a Randomized Pretest-Posttest Design and conducted at the Hospital Inpatient Ward Dr. Kariadi and Ketileng Semarang from January to December 2014 for all first ischemic stroke patients with Type 2 Diabetes Mellitus. Subjects were divided into groups of 26 controls and 28 patients treated groups. Treatment group were given simvastatin 20 mg each daily for 24 weeks in 28 subjects with a history of acute ischemic stroke and type 2 Diabetes mellitus. Examine the CIMT at the 1st week and 24th week. The normality of the data were tested using Shapiro Wilk and the differences analyzed by using Paired t-test and independent t test. RESULT : There was a significant differences between delta carotid intima-media thickness on administration of simvastatin for ischemic stroke patients with type 2 diabetes mellitus (p=0,008). CONCLUSION : Simvastatin significantly decreases CIMT on ischemic stroke patients with type 2 diabetes mellitus. Keyword : simvastatin, ischemic stroke, carotid intima-media thickness, type 2 diabetes mellitus   LATAR BELAKANG :Stroke iskemik memiliki angka insidensi terbanyak yaitu 70-80% kasus stroke. Ketebalan Intima-media karotis berhubungan dengan terjadinyastroke pada usia tua.Pasien dengan Diabetes mellitus tipe 2 memiliki kemungkinan yang lebih besar mengalami penebalan intima-media carotis. Simvatatin menghambat proses aterotrombosis. TUJUAN :Untuk menganalisis pengaruh simvastatin terhadap ketebalan intima-media karotis pada pasien stroke iskemik dengan diabetes mellitus tipe 2. METODE :Penelitian ini adalah dengan Randomized Pretest-Posttest Design dan telah dilakukan di Rawat Jalan RSUP dr. Kariadi dan poli saraf rawat jalan RSUD Kota Semarang mulai Januari sampai dengan Desember 2014 untuk semua pasien stroke iskemik pertama kali dengan diabetes mellitus tipe 2. Subjek dibagi menjadi kelompok kontrol 26 pasien dan kelompok perlakuan 28 pasien. Kelompok perlakuan diberi simvastatin 20 mg sehari selama 24 minggu pada 28 subjek stroke iskemik dengan  diabetes mellitus tipe 2. Pemeriksaan ketebalan intima-media karotis dilakukan pada minggu ke-1 dan minggu ke-24. Data kemudian di uji normalitasnya menggunakan Saphiro wilk, lalu di analisis menggunakan uji beda paired t testdan independent t test. HASIL :  Kelompok perlakuan didapatkan penurunan ketebalan tunika intima arteri karotis (0,395 + 0,46; p=0,514), KESIMPULAN : Pemberian simvastatin menurunkan ketebalan intima-media karotis secara bermakna pada pasien stroke iskemik dengan diabetes mellitus tipe 2. Kata Kunci     :simvastatin,stroke iskemik, ketebalan intima-media karotis, diabetes mellitus tipe 2
