AbstrakLeukemia merupakan penyakit keganasan sel darah yang berasal dari sumsum tulang ditandai oleh proliferasi sel-sel darah putih, dengan manifestasi adanya sel-sel abnormal dalam darah tepi. Pada tahun 2006, leukemia berada pada urutan ke-5 dari keseluruhan penderita kanker di Indonesia. Leukemia kronik merupakan leukemia yang paling sering terjadi pada dewasa dan lanjut usia. Secara umum leukemia kronik diklasifikasikan atas Leukemia Granulositik Kronik (LGK) dan Leukemia Limfositik Kronik (LLK). Leukemia kronik yang perjalanannya lambat dan diiringi oleh gejala yang tidak khas, maka penelitian ini bertujuan untuk mengetahui gambaran laboratorium leukemia kronik di bagian Peyakit Dalam RSUP DR. M. Djamil Padang. Jenis penelitian ini adalah deskriptif retrospektif. Instrumen yang digunakan pada penelitian ini adalah data sekunder yang diperoleh dari Instalasi Rekam Medik RSUP Dr. M. Djamil Padang berupa data pasien leukemia kronik yang dirawat di Bagian Penyakit Dalam RSUP Dr. M. Djamil Padang sejak 1 Januari 2010 – 31 Desember 2012. Hasil penelitian ini menunjukkan bahwa dari 16 kasus leukemia granulositik kronik terdapat 37,5% pasien mengalami anemia sedang, 100% leukositosis, jumlah trombosit dapat menurun, normal, dan meningkat dengan presentase masing-masing 25%, 25%, dan 50%. Gambaran eritrosit sebagian besar normositik anisositosis. Separuh pemeriksaan darah tepi menunjukkan peningkatan persentasi mielosit, 31,25% menunjukkan peningkatan persentasi metamielosit dan eosinofil, serta sebagian besar menunjukkan presentasi blast. Sedangkan gambaran sumsum tulang hiperseluler, penekanan eritropoetik, mielopoetik hiperaktif, dan trombopoetik dalam batas normal. Leukemia limfositik kronik yang terdiri dari 1 kasus menunjukkan gambaran laboratorium berupa anemia sedang, leukositosis, trombositopenia, gambaran eritrosit nomokrom anisositosis, peningkatan jumlah leukosit, peningkatan jumlah limfosit, presentasi smudge cell, dan ditemukan presentasi blast pada darah tepi, tetapi selularitas tidak dapat dinilai.Kata kunci: leukemia kronik, darah tepi, BMPAbstractLeukemia is a malignant disease of blood cells derived from the bone marrow characterized by the proliferation of white blood cells, with the manifestation of the abnormal cells in the peripheral blood. In 2006, leukemia was ranked 5th of all cancer patients in Indonesia. Chronic leukemia is the most common leukemia in adult and the elderly. In general, chronic leukemia classified on chronic myelocytic leukemia (CML) and chronic lymphocytic leukemia (CLL). The onset of chronic leukemia is insidious and accompanied by symptoms that are not typical, this research aims to describe the laboratory findings of chronic leukemia patients treated at Internal Medicine Department of Dr. M. Djamil Hospital Padang.This research is a retrospective descriptive research. The instruments used in this research are the secondary data derived from the Medical Record Departement Dr. M. Djamil Hospital Padang in the form of leukemia chronic patients’ data who were treated in Internal Medicine Department of Dr. M. Djamil Hospital Padang since January 1st 2010 – December 31st 2012. The results of this research showed that of 16 cases of chronic myelocytic leukemia contained 37.5% of the patients had moderate anemia, leukocytosis 100%, platelet count can be decreased, normal, and increased the percentage of each 25%, 25%, and 50%. The morphology of erythrocytes mostly normocytic anisocytosis. Half of peripheral blood examination showed an increase in the percentage of myelocyte, 31.25% showed an increase in the percentage metamyelocyte and eosinophils, as well as most of the shows presentation blast. The bone marrow are hypercellular, compressing erythropoietic, myelopoietic hyperactivity and thrombopoietic mostly normal in number. Chronic lymphocytic leukemia consisting of 1 case shows the laboratory findings are moderate anemia, leukocytosis, thrombocytopenia, the morphology of erythrocyte is normochromic anisocytosis, leukocytes increase in number, increase in the number of lymphocytes, presentations smudge cells, and blast presentation is found in the peripheral blood, but the cellularity not be assessed.Keywords: chronic leukemia, peripheral blood, BMP

Background: Atherosclerosis, a chronic inflammatory disease characterized by the buildup of plaque within arteries, remains a leading cause of cardiovascular morbidity and mortality. RNA interference (RNAi) has emerged as a promising therapeutic strategy for atherosclerosis by targeting genes involved in plaque formation and progression. This meta-analysis aimed to evaluate the efficacy of RNAi in preclinical models of atherosclerosis. Methods: A systematic search of PubMed, Embase, and Web of Science databases was conducted from January 2013 to December 2023 to identify preclinical studies investigating the impact of RNAi on atherosclerotic plaque progression. Studies utilizing various RNAi modalities (siRNA, miRNA mimics/inhibitors, shRNA) targeting different genes involved in atherosclerosis were included. The primary outcome was plaque size reduction. Secondary outcomes included changes in plaque composition, lipid profiles, and inflammatory markers. A random-effects model was used to pool data and calculate standardized mean differences (SMD) with 95% confidence intervals (CI). Heterogeneity was assessed using the I² statistic. Results: Seven preclinical studies met the inclusion criteria, encompassing a total of 210 animals. RNAi interventions significantly reduced atherosclerotic plaque size compared to controls (SMD -1.51; 95% CI -2.36 to -0.66; p<0.00001; I²=12%). Analysis of secondary outcomes revealed favorable effects of RNAi on plaque composition, with a significant decrease in lipid content and an increase in collagen content. Furthermore, RNAi significantly improved lipid profiles by reducing total cholesterol and LDL-cholesterol levels. A significant reduction in inflammatory markers, such as TNF-α and IL-6, was also observed. Conclusion: This meta-analysis provides compelling evidence supporting the therapeutic potential of RNAi in attenuating atherosclerotic plaque progression in preclinical models. RNAi effectively reduced plaque size, improved plaque stability, and modulated lipid metabolism and inflammation.

Introduction. Diabetic kidney disease (DKD) is a major microvascular complication of diabetes mellitus, characterized by persistent albuminuria and a progressive decline in glomerular filtration rate (GFR), making it a leading cause of chronic kidney disease (CKD) and end-stage renal disease. Vascular endothelial growth factor-A (VEGF-A) is implicated in the pathogenesis of DKD, being overexpressed in the kidneys and contributing to increased vascular permeability, inflammation, and fibrosis. Albuminuria, an early indicator of renal damage in DKD, is a strong predictor of CKD progression and cardiovascular events. The urine albumin-to-creatinine ratio (UACR) is the recommended test for detecting and monitoring albuminuria. This study aimed to investigate the correlation between serum VEGF-A levels and UACR in patients with DKD. Methods. This cross-sectional analytical observational study involving DKD patients at the Outpatient Clinic of Dr. M. Djamil General Hospital Padang from May to October 2024. Demographic and clinical data were collected. Blood samples were taken for serum VEGF-A measurement using ELISA, and morning spot urine samples were collected for UACR measurement using immunoturbidimetry. Correlation analysis was performed using the Spearman test. Ethical approval was obtained from the Health Research Ethics Committee of Dr. M. Djamil General Hospital Padang. Results. A total of 30 PGD patients were included in the study. The mean age was 61.9 years (SD 9.75), and 53.3% of the participants were male.The mean serum VEGF-A level in DKD patients was 131.34 (SD 83.9) pg/ml, and the mean UACR was 403.90 (SD 53.1) mg/g creatinine. There was a very strong positive correlation between serum VEGF-A levels and UACR (r = 0.993, p < 0.05). Conclusions. Serum VEGF-A levels are very strongly and positively correlated with UACR in DKD patients. Serum VEGF-A may serve as a potential marker for assessing DKD progression and risk of complications, as well as a potential therapeutic target.
