"Aterosklerosis sampai saat ini merupakan penyebab utama morbiditas dan mortalitas di negara maju. Meskipun modifikasi faktor risiko di negara maju telah dapat menurunkan kekerapan aterosklerosis namun penurunan ini mulai menunjukkan grafik yang mendatar. Keadaan ini merangsang para peneliti untuk mencari faktor pajanan lingkungan termasuk faktor infeksi yang dapat mempengaruhi proses aterosklerosis. Telah dilakukan penelitian potong lintang dari bulan Maret 1998 sampai Agustus 1998 terhadap 122 orang pasien yang secara klinis menunjukkan penyakit jantung koroner yang menjalani kateterisasi jantung, terdiri dari 92 orang laki-laki dan 30 orang perempuan dengan rerata umur 55 tahun. Pasien diperiksa secara klinis dan laboratorium (gula darah, kolesterol, trigliserida dan antibodi terhadap C.pneumoniae, Cytomegalovirus dan H.pylori). Pada penelitian ini didapatkan perbedaan kadar kolesterol, trigliserida dan HDL antara kelompok stenosis koroner dan non stenosis. Sedangkan kadar antibodi C.pneumoniae, Cytomegalovirus, H.pylori tidak berbeda bermakna. Penelitian ini belum dapat menyimpulkan pengaruh antibodi terhadap aterosklerosis karena pada kelompok non stenosis tidak dapat disingkirkan kemungkinan terjadinya aterosklerosis mengingat rerata umur subyek penelitian 55 tahun. Penelitian mengenai interaksi infeksi dengan risiko tradisional serta gender dan nutrisi diperlukan untuk mendapat jawaban yang lebih jelas tentang pengaruh infeksi terhadap aterosklerosis.

Atherosclerosis is still the chief cause of morbidity and mortality in developed nations. Even though in developed nations the modification of risk factors is able to reduce the prevalence rate of atherosclerosis, such reduction is starting to slow down. Such condition has stimulated researchers to identify environmental exposure, including infection, that can influence the process of atherosclerosis. This cross sectional study was conducted from March to August 1998, on 122 patients that clinically demonstrate coronary heart disease and have underwent cardiac catheterization, 92 males and 30 females with an average age of 55 years. Patients undergo clinical and laboratory evaluation (blood glucose, cholesterol, triglyceride, and antibody for C.pneumoniae. Cytomegalovirus, and H.pylori). We found a significant difference in cholesterol, triglyceride, and HDL levels in those with coronary stenosis and those without. However, we did not find a significant difference in the levels of C.pneumoniae, Cytomegalovirus, and H.pylori antibodies. This study is unable to conclude the influence of these antibodies on atherosclerosis, since in the non-stenosis group, we cannot eliminate the possibility of atherosclerosis, since the average age of study subject is 55 years. Studies on the interaction between infection and traditional risk factors as well as gender and nutrition is needed to find a clear answer of the influence of infection in atherosclerosis.

"Introduction: The most common cause of the peripheral arterial disease (PAD) is atherosclerosis. PAD is associated with other atherosclerotic diseases such as renal artery stenosis (RAS). Life expectancy decreases in patients with RAS, especially those whose stenosis is above 60% but has not reached the stage of chronic kidney failure. This study aims to determine the prevalence of RAS in PAD patients, the relationship between angiographic scoring system (ANGIO Score), history of hypertension, and diabetes mellitus with the degree of RAS. Method: This research was a cross-sectional study conducted at Cipto Mangunkusumo Hospital from February to May 2019. Patients with a diagnosis of lower extremity PAD and had been assessed with CT angiography examination, were included in this study. The degree of RAS and ANGIO Score were calculated. Sampling was done by the total sampling method. Results Most patients were women 33 (50.8%), while men were 32 (49.2%). 90.8% of the patients had diabetes, while 61.5% of the sample had hypertension. Grade 1 RAS was the most found. There was no correlation between ANGIO Score on age, sex, and diabetes mellitus, but there was a significant relationship with hypertension. There was a relationship between RAS with age and hypertension, but there was no relationship with diabetes mellitus and gender. ANGIO Score and RAS had a significant relationship (p <0.001). Conclusion: There was a relationship between the ANGIO Score and the severity of RAS. The cut-off score of 9 for the ANGIO Score had a sensitivity of 85.7% and a specificity of 61.4% for predicting RAS."

"ABSTRAKLatar Belakang: Aterosklerosis merupakan penyakit sistemik, bisa terjadi di seluruh pembuluh darah. Pada arteri karotis terjadi penebalan tunika intima yang dapat dideteksi menggunakan penunjang non invasif yaitu dengan ultasound. Pada tungkai dapat dilakukan pemeriksaan non invasif yaitu Ankle-Brachial Index (ABI) dan Toe-Brachial Index (TBI) untuk mengetahui adanya penyakit arteri perifer, dengan asumsi bahwa adanya penurunan ABI atau TBI menunjukkan sudah ada stenosis. Berdasarkan hal ini diduga terdapat hubungan antara ABI dan TBI dengan Carotid Intima Media Thickness (CIMT). Tujuan: Mendapatkan hubungan antara ABI dan TBI dengan CIMT. Metode: Dilakukan studi potong lintang pada 36 pasien diabetes tipe II. Dilakukan pemeriksaan ABI dan TBI bila memenuhi kriteria Penyakit Arteri Perifer, dilanjutkan dengan pemeriksaan ultrasound untuk mengetahui ketebalan tunika intima karotis. Hubungan antara ABI dan TBI dengan CIMT dihitung dengan Spearman. Hasil: Rerata ABI yang diperoleh adalah 0,97 ± 0,15, rerata TBI 0,56 ± 0,1. Nilai tengah CIMT 0,96 (0,77 - 3,60). Tidak terdapat hubungan antara ABI dengan CIMT (r=-259, p=0,127) dan terdapat hubungan negatif bermakna antara TBI dengan CIMT (r=-0,47, p=0,004). Simpulan: Tidak terdapat hubungan antara ABI dengan CIMT. Terdapat hubungan negatif bermakna antara TBI dengan CIMT.

"Analisis histomorfometrik pembentukan lesi aterosklerosis koroner pada model tikus (Rattus novergicus) periodontitis. Penyakit kardiovaskuler perupakan penyakit paling mematikan di dunia dan penyebab utamanya adalah aterosklerosis. Paradigma baru menjelaskan bahwa inflamasi kronis seperti periodontitis dipertimbangkan sebagai faktor risiko terjadinya aterosklerosis. Periodontitis menyebabkan bakteremia yang berpengaruh terhadap inflamasi vaskuler. Keadaan ini mempengaruhi sel endotel dan oksidasi lipid sehingga meningkatkan resiko aterosklerosis. Tujuan: Penelitian ini bertujuan untuk membuktikan pengaruh periodontitis terhadap pembentukan lesi aterosklerosis koroner. Metode: Penelitian ini merupakan eksperimen menggunakan the post test only control group design. 12 sampel tikus dibagi atas kelompok kontrol (K) tanpa perlakuan dan kelompok periodontitis (P) dibuat dengan pemasangan wire ligature dan injeksi Porphyromonas gingivalis pada M1 rahang bawah kiri selama 28 hari. Pada hari ke-29 tikus didekaputasi, arteri koroner diambil dan dibuat preparat histologi. Analisis histomorfomerik dilakukan pada morfologi dungkul (deskriptif) dan ketebalan dinding arteri (statistik dengan uji T test). Hasil: Hasil penelitian menunjukkan bahwa terbentuknya dungkul arteri lebih banyak pada kelompok Periodontitis (83,33%) daripada kelompok Kontrol (16,67%). Dinding arteri kelompok periodontitis juga lebih tebal (2,22±0,35µm) secara signifikan dibandingkan kelompok kontrol (1,28±0,20µm) (p<0,05). Simpulan: Periodontitis secara independen dapat mempengaruhi gambaran histomorfometrik pembentukan lesi aterosklerosis koroner.

Cardiovascular disease is the most deadly disease in the world and the main cause is atherosclerosis. New paradigm explains that chronic inflammation such as periodontitis is considered to be a risk factor for atherosclerosis. Periodontitis causes bacteremia affecting vascular inflammation. This situation affects the endothelial cells and lipid oxidation thereby increasing the risk of atherosclerosis. This study aimed to prove the effect of periodontitis on coronary atherosclerotic lesion formation. Methods: This was an experimental study using the post-test only control group design. Samples were 12 rats divided into control group (K) without treatment and periodontitis (P) was made with the installation of wire ligature and injection of Porphyromonas gingivalis on the left mandibular M1 for 28 days. On day 29, mice were decaputated, coronary artery was taken and histological slides were made. Histomorphometrical analysis was calculated on dungkul (descriptive) and the thickness of the arterial wall (with test statistic T test). Results: The results showed higher formation of arterial dungkul on Periodontitis group (83.33%) than the control group (16.67%). Arterial wall was also thicker periodontitis group (2.22±0.35µm) (p<0.05) than the control group (1.28±0.20µm). Conclusion: Periodontitis can independently affect the coronary atherosclerotic lesion formation."

Aterosklerosis adalah fenomena penyempitan arteri karena penumpukan plak di dinding arteri sebagai akibat dari suatu pola hidup tidak sehat. Menurut pendekatan ilmu sosial, pola hidup yang salah dapat ditularkan kepada orang lain disekitarnya. Bentuk penanganan pasien aterosklerosis adalah melalui operasi bypass yang harus dilakukan oleh dokter spesialis dan di rumah sakit tertentu, yang keduanya memiliki jumlah yang terbatas. Jika jumlah pasien dengan komplikasi aterosklerosis terus bertambah, itu akan berdampak pada pengobatan yang tidak lagi optimal. Penelitian ini bertujuan untuk membangun model penyebaran aterosklerosis tanpa dan dengan mempertimbangkan pengaruh keterbatasan sumber daya rumah sakit, yang dikenal sebagai efek saturasi. Kedua model dibentuk dengan membagi kompartemen manusia dalam populasi yang rentan, terinfeksi aterosklerosis, dan penderita aterosklerosis yang menjalani pengobatan. Model-model yang telah dibangun kemudian dianalisis secara analitik dan numerik. Studi analitik dilakukan untuk menemukan dan menganalisis titik keseimbangan, menentukan bilangan reproduksi dasar (R0), dan menyelidiki keberadaan bifurkasi dari model yang dibangun. Bifurkasi maju, mundur dan maju dengan hysteresis muncul dari model yang telah terbentuk. Hasil analitik didukung oleh simulasi numerik terkait elastisitas dan sensitivitas R0 serta simulasi autonomous.

Atherosclerosis is a narrowing of the arteries due to the buildup of plaque on the artery walls resulting from an unhealthy lifestyle. According to the social science approach, the wrong lifestyle can be ”infection” to other people. The form of treatment for atherosclerosis patients is through bypass surgery, which must be performed by specialists and in specific hospitals, both of which have a limited number. If the number of patients with atherosclerosis complications continues to increase, it will result in no longer optimal treatment. This study aims to build a model of atherosclerosis spread without and taking into account the effect of limited hospital resources, known as the saturation effect. Both models were formed by dividing the human compartment into populations susceptible, infected with atherosclerosis, and people with atherosclerosis who are undergoing treatment. The models that have built are then analyzed analytically and numerically. Analytical studies carried out to find and analyze the equilibrium point, determine the basic reproduction number (R0), and investigate the existence of a bifurcation of the built model. Forward bifurcation, backward bifurcation, and forward bifurcation with hysteresis appear from the model that has formed. The analytical results supported by numerical simulations related to elasticity and sensitivity of R0 as well as autonomous simulations.

"Latar Belakang: Carotid stiffness (CS) merupakan perubahan fungsional pada arteri karotis akibat aterosklerosis. Diabetes mellitus tipe 2 (DMT2) akan mempercepat dan memperburuk aterosklerosis sehingga meningkatkan risiko kejadian kardiovaskular. Sampai saat kini belum ada data di Indonesia tentang CS pada pasien penyakit jantung koroner (PJK) stabil dengan DMT2 yang menggunakan sistem otomatis echotracking ultrasound berbasis frekuensi radio. Penelitian ini bertujuan untuk membandingkan CS pada pasien PJK stabil dengan dan tanpa DMT2. Metode: Comparative cross-sectional antara kelompok pasien PJK stabil dengan dan tanpa pasien DMT2. Pemeriksaan CS dilakukan dengan posisi pasien berbaring telentang secara non-invasif pada 1 cm sebelum bulbus arteri karotis kiri dan kanan menggunakan automatic echotracking radiofrequency-based ultrasound dengan probe linear 3-13 MHz. Pengukuran CS dilakukan sebanyak enam kali pada masing-masing sisi arteri karotis dengan nilai tertinggi rerata carotid Pulse Wave Velocity (car-PWV) sebagai nilai CS individu. Hasil: Dari total 42 pasien (21 pasang) yang diperiksa didapatkan nilai rerata car-PWV pasien PJK stabil dengan DMT2 lebih tinggi dibandingkan pasien PJK stabil tanpa DMT2 (9,8±1,3m/s vs 6,7±1,3m/s, p< 0,001). Kesimpulan: Nilai carotid stiffness pasien PJK stabil dengan DMT2 lebih tinggi dibandingkan pasien PJK stabil tanpa DMT2.

Background: Carotid stiffness (CS) represents the functional changes in carotid arteries due to atherosclerosis. Progression of atherosclerosis was more accelerated in type 2 diabetes mellitus (T2DM) compared to non-diabetic patient, thus increasing the risk of cardiovascular events. Until now there is no data of CS in stable coronary artery disease (CAD) with T2DM in Indonesia using automatic echotracking radiofrequency-based ultrasound. The aim of this study was to compare CS in stable CAD with and without T2DM patient.

Method: Comparative cross-sectional between group of stable CAD with and without T2DM patients. CS was measured in patient lying down non-invasively at 1 cm proximal to bulbus of the left and right carotid artery using automatICechotracking radiofrequency-based ultrasound system, 3-13 MHz linear probe. The highest mean carotid pulse wave velocity (car-PWV) value of six measurements of both side was used as an individual CS.

Result: Total 42 patients (21 pairs) was examined. Mean value of car-PWV stable CAD with T2DM patient is higher than stable CAD without T2DM patient (9.8 1.3 m/s vs. 6.7 1.3 m/s, p<0.001).

Conclusion: Carotid stiffness value of stable CAD with T2DM patient is higher than stable CAD without T2DM patient."

"Latar belakang: Kejadian aterosklerosis pada pasien artritis reumatoid (AR) dilaporkan semakin lama semakin meningkat. Penyebab aterosklerosis pada AR tidak hanya disebabkan oleh faktor risiko tradisional, akan tetapi antibodi anti-CCP yang merupakan autoantibodi spesifik pada AR juga berperan dalam patogenesis aterosklerosis. Data prevalensi aterosklerosis dan penelitian mengenai hubungan antara antibodi anti-CCP dengan aterosklerosis belum pernah dilakukan pada populasi pasien AR di Indonesia. Tujuan: Mengetahui prevalensi aterosklerosis pada pasien AR dan menentukan asosiasi antara antibodi anti-CCP dengan aterosklerosis pada pasien AR. Metode: Penelitian ini menggunakan desain potong lintang dan pengambilan sampel dilakukan dengan metode consecutive. Subjek penelitian adalah pasien AR dewasa berusia diatas 18 tahun yang didiagnosis sesuai kriteria ACR/ EULAR 2010 yang datang berobat ke Poliklinik Reumatologi RSCM pada bulan September 2012 sampai Maret 2013. Antibodi anti-CCP diperiksa dengan metode ELISA. Adanya aterosklerosis ditentukan melalui pemeriksaan USG karotis bilateral yang dilakukan oleh satu orang operator dan tidak mengetahui latar belakang klinis pasien. Hubungan antara anti-CCP dengan aterosklerosis dinilai dengan menghitung crude odds ratio (OR) disertai interval kepercayaan (IK) 95%-nya. Peran variabel perancu dinilai dengan menggunakan analisis regresi logistik untuk mendapatkan adjusted OR. Hasil: Dari 86 subjek penelitian didapatkan 90,7% berjenis kelamin perempuan dengan median usia 49,5 (rentang 20 sampai 70) tahun. Prevalensi aterosklerosis didapatkan sebesar 50% (IK95% 0,39 – 0,61). Proporsi aterosklerosis pada kelompok subjek dengan antibodi anti-CCP positif (51,5%) tidak jauh berbeda dengan kelompok antibodi anti-CCP negatif (49,1%). Setelah disesuaikan dengan beberapa variabel perancu, tidak didapatkan hubungan yang bermakna antara antibodi anti-CCP dengan aterosklerosis (adjusted OR 1,197; IK95% 0,43 - 3,29). Simpulan: Prevalensi aterosklerosis pada pasien AR sebesar 50% (IK95% 0,39 - 0,61). Tidak didapatkan hubungan yang bermakna antara antibodi anti-CCP dengan aterosklerosis pada pasien AR.

Background: Atherosclerosis is markedly increased in patients with rheumatoid arthritis (RA). Traditional risk factors not only account for atherosclerosis but also autoantibodies in RA especially anti-cyclic citrullinated peptides (anti-CCP) is the one of autoantibody highly specific for RA play a role in the pathogenesis of atherosclerosis. However, in Indonesia there was no data regarding the prevalence of atherosclerosis in RA patients.

Objectives: The aim of this study was to described the prevalence of atherosclerosis and to determine the association of anti-CCP antibodies with atherosclerosis in RA patients.

Methods: A cross sectional study was conducted in Rheumatology outpatient clinic Department of Internal Medicine, Cipto Mangunkusumo Hospital with consecutive sampling. Study subjects were recruited from September 2012 to March 2013 that RA patients diagnosed according to American College of Rheumatology (ACR)/ European League Againts Rheumatism/ (EULAR) 2010 criteria. Anti-CCP antibodies was determined by enzyme-linked immunosorbent assays (ELISA) test. Carotid intima-media thickness represent of atherosclerosis was measured by using Ultrasound (USG B-mode) and it was done by one independent operator without knowing clinical background of the patients. Association of anti-CCP with atherosclerosis was performed by chi-square test in order to get crude odds ratio (OR) with CI95% and logistic regression test was assigned to obtain adjusted OR.

Results: Out of eighty six RA patients aged 20 to 70 years old revealed in this study with median age 49.5 years and female gender as the commonest (90.7%). Fourty three (50%; CI95% 0.39 to 0.61) RA patients had carotid atherosclerosis. Atherosclerosis in RA patients with anti-CCP positive was seen in 51.5% and 49.1% in anti-CCP negative. After a set of adjustment towards the confounding factors, there was no significant association between anti-CCP antibodies and atherosclerosis (adjusted OR 1.197; CI95% 0.43 to 3.29).

Conclusion: This study demonstrates that the prevalence of atherosclerosis in RA patient is 50% (CI95% 0.39 to 0.61). The role of anti-CCP antibodies and atherosclerosis in patients with RA did not hold in this study."
