"Non-arteritic anterior ischemic optic neuropathy (NAION) adalah penyakit multifaktorial yang mekanismenya belum diketahui secara pasti, namun hiperkoagulasi diduga merupakan faktor yang berperan pada NAION. Karena merupakan penyakit mikrovaskular, maka aktivasi koagulasi pada fase awal dapat menyebabkan koagulasi pada NAION. Penelitian ini bertujuan untuk mengetahui peran hiperkoagulasi pada kejadian NAION dalam upaya memberikan tata laksana yang lebih baik pada pasien NAION. Penelitian dilakukan pada bulan Oktober 2020 hingga April 2022 di Poliklinik Mata Divisi Neuro-oftalmologi FKUI-RSCM Kirana. Subjek adalah pasien NAION yang dibagi menjadi kelompok hiperkoagulasi dan non-hiperkoagulasi. Penelitian potong lintang dilakukan untuk menilai penanda koagulasi dini yaitu E-selectin, P-selectin, microparticle tissue factor (MPTF), prothrombin fragment 1+2 (PF1+2), dan hasil pemeriksaan penunjang berupa optical coherence tomography (OCT), OCT angiography (OCTA), dan Humphrey visual field (HVF). Uji klinis eksperimental dilakukan untuk menilai efektivitas terapi hiperkoagulasi dalam waktu 1 bulan. Terdapat 64,3% subjek NAION dengan hiperkoagulasi dan terjadi aktivasi penanda koagulasi dini pada kedua kelompok. Kesesuaian lokasi OCTA dengan ganglion cell inner plexiform layer (GCIPL) ditemukan pada 33% subjek, retinal nerve fiber layer (RNFL) pada 6,7% subjek, dan HVF pada 40% subjek, namun tidak terdapat korelasi jumlah sektor atau kuadran yang terkena. Nilai GCIPL dan HVF tidak berkorelasi dengan OCTA, di kuadran yang terkena, RNFL berkorelasi dengan OCTA. Kelompok terapi hiperkoagulasi menunjukkan penurunan perfusi lebih sedikit. Tajam penglihatan membaik pada 57,2% subjek di kelompok NAION dengan hiperkoagulasi dan 42,9% di kelompok NAION nonhiperkoagulasi. Berdasarkan fungsi lapang pandang, kedua kelompok menunjukkan perbaikan pada sebagian besar subjek (71,4% pada kelompok NAION dengan hiperkoagulasi dan 85,8% pada kelompok NAION nonhiperkoagulasi). Disimpulkan hiperkoagulasi berperan pada mekanisme NAION, sehingga tata laksana terkait hiperkoagulasi penting pada pasien NAION dalam mencapai luaran klinis yang lebih baik.

Non-arteritic anterior ischemic optic neuropathy (NAION) is a multifactorial disease with an uncertain mechanism. Hypercoagulability is believed to be one of the factors involved in NAION. Considering that NAION is a microvascular disease, this study assumes that coagulation activation in the early phase is sufficient to cause a coagulation state in NAION. The aim of this research is to evaluate the role of hypercoagulability in the occurrence of NAION in order to provide better management for NAION patients. The subjects were NAION patients divided into hypercoagulability and non-hypercoagulability groups. A cross-sectional study was conducted to assess early coagulation markers, namely E-selectin, P-selectin, microparticle tissue factor (MPTF), and prothrombin fragment 1+2 (PF1+2), as well as ancillary tests such as optical coherence tomography (OCT), OCT angiography (OCTA), and Humphrey visual field (HVF). An experimental clinical trial was conducted to evaluate the effectiveness of hypercoagulation therapy within one month. It was found that 64.3% of NAION subjects had hypercoagulability. Early coagulation marker activation occurred in both groups. There was a concordance between OCTA and ganglion cell inner plexiform layer (GCIPL) location in 33% of subjects, retinal nerve fiber layer (RNFL) in 6.7% of subjects, and HVF in 40% of subjects. However, no correlation was found regarding the number of affected sectors or quadrants. GCIPL and HVF values did not correlate with OCTA, whereas in the affected quadrant, RNFL correlated with OCTA. The hypercoagulation therapy group showed less perfusion reduction. Visual acuity improved in 57.2% of subjects in the hypercoagulability NAION group and 42.9% in the non-hypercoagulability NAION group. Based on visual field function, both groups showed improvement in the majority of subjects (71.4% in the hypercoagulability NAION group and 85.8% in the non- hypercoagulability NAION group). It can be concluded that hypercoagulability plays a role in the mechanism of NAION, thus emphasizing the importance of managing hypercoagulability in NAION patients to achieve better clinical outcomes."

"Diet tinggi lemak merupakan salah satu faktor risiko hiperlipidemia. Hiperlipidemia menyebabkan aktivasi platelet dengan peningkatan ekspresi Platelet Selectin (P-Selectin) yang bermanifestasi menjadi penyakit jantung koroner dan stroke. Penelitian ini bertujuan mengembangkan model tikus hiperlipidemia dengan memberikan variasi komposisi diet tinggi lemak ditambah diet tinggi karbohidrat serta menganalisis terjadinya aktivasi platelet melalui peningkatan ekspresi P-Selectin. Variasi komposisi diet tinggi lemak yang diberikan berupa 40% kuning telur puyuh dan 25% lemak kambing pada kelompok diet tinggi lemak 1, 30% kuning telur puyuh dan 35% lemak sapi pada kelompok diet tinggi lemak 2, serta 50% lemak kambing dan 15% mentega pada kelompok diet tinggi lemak 3. Setiap kelompok diet tinggi lemak juga diberikan 20% fruktosa, 2% kolesterol murni, 0,5% asam kolat, dan 12,5% minyak kelapa. Rerata kadar kolesterol total, trigliserida, dan P-Selectin kelompok diet tinggi lemak 1 sebesar 139,68 ± 11,88 mg/dL; 142,06 ± 11,76 mg/dL; dan 26,01 ± 7,35 ng/mL. Rerata kadar kolesterol total, trigliserida, dan P-Selectin kelompok diet tinggi lemak 2 sebesar 161,14 ± 14,42 mg/dL; 185,94 ± 13,36 mg/dL; dan 44,01 ± 9,38 ng/mL. Rerata kadar kolesterol total, trigliserida, dan P-Selectin kelompok diet tinggi lemak 3 sebesar 248,80 ± 7,48 mg/dL; 236,85 ± 7,53 mg/dL; dan 125,12 ± 39,62 ng/mL. Kondisi hiperkolesterolemia, hipertrigliseridemia, dan peningkatan ekspresi P-Selectin terjadi pada semua kelompok diet tinggi lemak. P-Selectin dengan kolesterol total berkorelasi sangat kuat dan positif sedangkan dengan trigliserida berkorelasi kuat dan positif. Dengan demikian, tiga variasi komposisi diet tinggi lemak ditambah diet tinggi karbohidrat dapat menghasilkan model hiperlipidemia dan meningkatkan ekspresi P-Selectin.

The high-fat diet was one of hyperlipidemia’s risk factors. Hyperlipidemia causes platelet activation with elevated expression through Platelet Selectin (P-Selectin) which manifests into coronary heart disease and stroke. This research aimed to develop hyperlipidemic rat models by varying the composition of high-fat diet plus high-carbohydrate diet and to analyze the platelet activation occurrence through elevated P-Selectin expression. Variations in the composition of the high-fat diet given were 40% quail egg yolk and 25% goat fat in the high-fat diet group 1, 30% quail egg yolk and 35% beef fat in the high-fat diet group 2, and 50% goat fat and 15% butter in the high-fat diet group 3. Each high-fat diet group was also given 20% fructose, 2% pure cholesterol, 0.5% cholic acid, and 12.5% coconut oil. The mean levels of total cholesterol, triglycerides, and P-Selectin in the high-fat diet group 1 were 139.68±11.88 mg/dL; 142.06±11.76 mg/dL; and 26.01±7.35 ng/mL. The mean levels of total cholesterol, triglycerides, and P-Selectin in the high-fat diet group 2 were 161.14±14.42 mg/dL; 185.94±13.36 mg/dL; and 44.01±9.38 ng/mL. The mean levels of total cholesterol, triglycerides, and P-Selectin in the high-fat diet group 3 were 248.80±7.48 mg/dL; 236.85±7.53 mg/dL; and 125.12±39.62 ng/mL. Conditions of hypercholesterolemia, hypertriglyceridemia, and elevated P-Selectin expression occurred in all high-fat diet groups. P-Selectin with total cholesterol was very strong and positively correlated while with triglyceride was strong and positively correlated. Therefore, three variations of high-fat diet composition plus the high-carbohydrate diet obtained hyperlipidemia model and elevated P-Selectin expression."

ABSTRACTBackground. The prevalence of Mitral stenosis (MS) remains significant in developingcountries related to prevalence of Rheumatic Heart Disease (RHD).In moderate-severe MSpatients enormous increase in turbulent region and shear stress causing dysfunction ofvascular endothelial, as consequence it increase the risk of thromboembolic complication. Pselectinis an adhesion molecule that play role in inflammation process, it express rapidly inminutes. Left Atrial Volume Index (LAVI) is superior parameter compare with otherechocardiography two dimension method to assess left atrial function.Methods. Study was designed as cross-sectional study involving 20 MS moderate-severepatients with MVA< 1.5 cm2 who performed successful Percutaneous transvenous BalloonMitral Valvulotomy (PBMV). Samples were taken consecutively from May 2013 to October2013 at the National Cardiovascular Center Harapan Kita Jakarta. Blood samples of Pselectinwere collected pre and post PBMV. The result was statistically analyzed by usingechocardiography data of LAVI prior PBMV to describe any association between expressionof P-selectin and atrial function.Result. In our study, we found no association between LAVI and expression of P-selectinlevel pre and post PBMV MS patient. This data describe in each of value of pre PBMV β= -0.103 (95% CI -0.251,0.045) p=0.16 and post PBMV β= 0.009 (95% CI -0.155,0.172) p=0.91After we performed linear regression with adjusted confounding variable including sex, age,and atrial fibrillation, still we found no association between LAVI and P-selectin level. Thisdata describe in each of value of pre PBMV β= -0.154 (95% CI -0.340,0.032) p=0.09 andpost PBMV β= -0.049 (95% CI -0.250,0.152) p=0.61.Conclusion. We found there is no difference in P-selectin level pre and post PBMV. There isno association between poor LAVI value and expression of P-selectin pre and post PBMV inMS."

"Latar belakang : Stenosis mitral (SM) masih merupakan masalah kesehatan yang penting di Indonesia. Pada SM terjadi peningkatan kadar P selectin karena disfungsi endotel dan aktivasi platelet. Komisurotomi mitral transvena perkutan (KMTP) merupakan tatalaksana baku untuk penderita SM yang dapat memperbaiki kemampuan aktivitas fisik yang pada akhirnya akan mempengaruhi kadar P selectin. Belum ada penelitian yang menghubungkan antara tingkat aktifitas fisik dengan kadar P Selectin 3 bulan pasca KMTP pada SM rematik. Metode : Penelitian ini merupakan penelitian potong lintang. Dari 56 subyek penelitian yang menjalani KMTP sejak bulan Mei 2013 sampai Februari 2014 di Rumah Sakit Jantung dan Pembuluh Darah Harapan Kita, didapatkan 35 sampel yang memenuhi kriteria penerimaan . Data klinis dan data ekokardiografi sebelum dan 3 bulan pasca KMTP diambil dari catatan medis. Dilakukan wawancara 3 bulan pasca KMTP. Tingkat aktivitas fisik dibagi menjadi 2 kelompok: kelompok 1 1-4 METs, kelompok 2 > 4 METs. Kadar P selectin diambil 3 bulan pasca KMTP. Selanjutnya dilakukan analisa statistik untuk mengetahui hubungan antara tingkat aktivitas fisik dengan kadar P Selectin 3 bulan pasca KMTP pada SM rematik. Hasil : Pasien yang akan menjalani KMTP memiliki rerata usia 40,00±11,58 tahun dengan proporsi perempuan lebih tinggi daripada laki-laki (74,3%) dan dengan proporsi irama sinus yang lebih tinggi daripada irama atrial (57,1%). Dari uji T didapatkan ada perbedaan bermakna rata-rata kadar P selectin 3 bulan pasca KMTP pada tingkat aktivitas fisik 1-4 METs dan > 4 METs, dimana rerata kadar P selectin 3 bulan pasca KMTP pada tingkat aktivitas fisik > 4 METs lebih rendah secara bermakna dibandingkan 1-4 METs (p=0,003). Setelah dilakukan analisa multivariat terlihat tingkat aktivitas fisik pasca KMTP tetap berpengaruh terhadap kadar P Selectin 3 bulan pasca KMTP (p=0,001). Area Katup Mitral (AKM) pasca KMTP berpengaruh terhadap kadar P selectin 3 bulan pasca KMTP (p=0,018), namun tingkat aktivitas fisik pasca KMTP lebih besar pengaruhnya dibandingkan AKM. Kesimpulan : Terdapat hubungan antara tingkat aktivitas fisik dengan kadar P selectin 3 bulan pasca KMTP dimana pada tingkat aktivitas yang lebih tinggi ( > 4 METs) kadar P selectin lebih rendah 10,489 ug/ml dibandingkan tingkatan aktivitas fisik 1-4 METs.

Background : Mitral stenosis (MS) is an important health problem in Indonesia. P selectin level in MS increases due to endothelial dysfunction and platelet activation. Percutaneous transvenous mitral commissurotomy (PTMC) is one of the management for MS patients. Thus, the physical activity can improve and in turn affect the level of P selectin. There has been no study link the level of physical activity with the level of P Selectin 3 months after of PTMC.

Method : This is a cross sectional study with 56 subjects who underwent PTMC from May 2013 to February 2014 at the Hospital of National Heart Centre Harapan Kita. Then, 35 samples met the inclusion criteria. Clinical and echocardiography data before and 3 months after PTMC were taken from medical records. Interviews were conducted 3 months after PTMC. Physical activity levels were divided into 2 groups: group 1 (1-4 METs) and group 2 (> 4 METs). Sample for P selectin was taken 3 months after PTMC. Further statistical analysis was done to determine the relationship between physical activity level with level of P Selectin 3 months after PTMC in rheumatic MS.

Result : Patients who will undergo PTMC have the mean age of 40.00 ± 11.58 years with a higher proportion of women than men (74.3%) and the proportion of sinus rhythm is higher than atrial rhythm (57.1%) . T-test analysis result showed significant difference in the average levels of P selectin 3 months after PTMC on the level of physical activity 1-4 METs and > 4 METs. The average P selectin levels on the level of physical activity in group with > 4 METs was significantly lower compared with group 1-4 METs (p = 0.003). After multivariate analysis, the physical activity level still has an effect on the P selectin levels 3 months after PTMC (p = 0.001). The Mitral Valve Area (MVA) after PTMC also has an effect on P selectin levels (p = 0.018). However, the level of physical activity after PTMC has a greater effect than MVA.

Conclusion : There is a relationship between the level of physical activity with P selectin levels 3 months after PTMC.Group with higher activity level (> 4 METs) have lower level of P selectin (with the mean difference levels of P Selectin 10,489 ug/ml)."
