Abstract

BACKGROUND: Syphilis and yaws are the treponemal infections which have become serious public health problems, and both are serologically indistinguishable. Developed serological tests for syphilis may also be used to diagnose yaws. In remote area, test modality with minimal requirements were needed. This study investigated the diagnostic value of syphilis rapid diagnostic test (RDT) in diagnosing syphilis and yaws.METHODS: For syphilis diagnostic test, serum samples were obtained from patients of outpatient clinic in Dr. Cipto Mangunkusumo National Central General Hospital who were sent for rapid plasma reagin (RPR) and Treponema pallidum haemagglutination assay (TPHA) to clinical laboratory of the hospital. The serum samples were collected and stored at -80°C until the day of testing for syphilis RDT and fluorescent treponemal antibody-absorption (FTA-Abs). For yaws diagnostic test, serum samples were obtained as a part of surveillance study of yaws among children 1-15 years old in West Halmahera. Venous blood samples were used for syphilis RDT and the sera were separated and were sent to Dr. Cipto Mangunkusumo National Central General Hospital for RPR, TPHA, and FTA-Abs tests.RESULTS: For syphilis diagnostic test, among 156 samples, 39 samples were positive with syphilis RDT. The sensitivity of syphilis RDT was similar to RPR and TPHA (100.0%), the specificity was same as TPHA (77.5%), but lower than RPR (84.8%) when compared to FTA-Abs IgM. The sensitivity of syphilis RDT was 62.5% and the specificity was 96.0% when compare to FTA-Abs IgG. For yaws diagnostic test, among 176 samples, 13 samples were positive with syphilis RDT. By using FTA-Abs IgM as gold standard for diagnosing yaws, the RDT have similar sensitivity (50.0%) with RPR and TPHA and syphilis RDT have similar specificity to TPHA (93.1%). If compared to FTA-Abs IgG, the sensitivity of syphilis RDT was 40.0% and the specificity was 98.0%.CONCLUSION: Syphilis RDT gives similar results with TPHA in syphilis and yaws cases. It may be used as a first line screening test latent or untreated syphilis and yaws because of good sensitivity. For yaws diagnosis Syphilis RDT, RPR, and TPHA have low sensitivity, however all those tests have an excellent agreement.KEYWORDS: FTA-Abs, rapid diagnostic test, syphilis, yaws

Abstract

BACKGROUND: Childhood acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy in Indonesia and often treated by methotrexate (MTX). Though it can be cured in 30-60% of patients, MTX resistance remains the major cause of treatment failure in childhood ALL. Previous sudies showed that its anti-leukemic property was moderated by MTX ability to inhibitmethylene tetra hydrofolate reductase (MTHFR) and thymidylate synthase (TS) in folate metabolism. This study investigates the correlation between MTHFR and TS polymorphism and MTX resistance in ALL children.METHODS: A total of 155 subjects obtained from all subjects prior to chemotherapy. DNA from blood samples were extracted and underwent polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) to evaluate MTHFR C677T and TS 5’-UTR 3R/3R polymorphism.RESULTS: There was significant correlation between MTHFR C677T and TS 5’-UTR 3R/3R gene polymorphism with MTX resistance. Subjectswith MTHFR C677T and TS 5’-UTR 3R/3R gene polymorphism were 4 times (p=0.007) and 6.4 times (p=0.001) more likely to be MTX resistant than those without gene polymorphisms, respectively.CONCLUSION: MTHFR C677T andTS 5’-UTR 3R/3R represent dominant gene polymorphism related to MTX resistance in childhood ALL.KEYWORDS: gene polymorphism, folate metabolism, acute lymphoblastic leukemia

Abstract

BACKGROUND: The health data of Central Java, Indonesia showed that diabetes mellitus (DM) was the second most increasing non-communicable disease in the province. More than 20 genes have been reported to be associated with DM. Calpain-10 (CAPN10) polymorphism has been reported to be associated with Type 2 Diabetes Mellitus (T2DM). However, the association between CAPN10 single nucleotide polymorphism (SNP)-19 and T2DM among Javanese ethnics has never been reported. Therefore, this study was conducted to investigate the association.METHODS: After fasting for 8 hours, blood samples were drawn from veins of 107 T2DM and 107 non diabetic subjects. A half of the drawn blood was collected for identification of CAPN10 SNP-19, and another half for measuring triglycerides and fasting blood glucose (FBG). Identification of CAPN10 SNP-19 was performed with polymerase chain reaction (PCR) method, while measurement of triglycerides and FBG with colorimetric enzymatic method.RESULTS: The number of T2DM Javanese subjects with 2R/3R and 3R/3R CAPN10 SNP-19 genotypes was significantly higher than the number of T2DM Javanese subjects with 2R/2R genotype (p=0.002). When each number of 2R/3R and 3R/3R T2DM subjects was compared with the number of 2R/2R T2DM subjects, the number of 2R/3R T2DM subjects was significantly higher than the number of 2R/2R T2DM subjects (p=0.000).CONCLUSION: Javanese subjects with 2R/3R and 3R/3R CAPN10 SNP19 genotypes might have susceptibility of T2DM.KEYWORDS: Calpain-10, CAPN10, polymorphism, type 2 diabetes mellitus, triglycerides, fasting blood glucose

Abstract

BACKGROUND: Statin is an anti-cholesterol drug that is widely prescribed throughout the world. Statins are mainly used to treat and prevent cardiovascular disease. Several studies have found the pleiotropic effect of statin. However, related effect of statin in kidney failure is still unclear. Ischemic-reperfusion (I/R) injury is a major cause of acute kidney failure. This study aims to determine the effect of simvastatin on kidney function and glomerular conditions by periodic acid-schiff staining in I/R injury.METHODS: Eighteen male Swiss mice were grouped into sham operation group (GSO), I/R injury group (GIRI), and simvastatin group (GSIM). The GSO group was performed by sham operation and pretreatment of 1% carboxymethylcellulose (CMC) for 3 days. The GIRI group was performed by I/R procedure and pretreatment of 1% CMC for 3 days and the GSIM group was performed by I/R procedure and pretreatment of 10 mg/kg BW simvastatin for 3 days. Blood urea nitrogen (BUN) and creatinine serum were assessed to determine kidney function. Histopathological analysis of glomerulosclerosis was assessed by the extent of glomerular damage (sclerosis), capillary loops, and synechia. The data were analyzed by one-way ANOVA followed by post hoc Tukey’s test (p<0.05).RESULTS: The creatinine and BUN levels in the GIRI group were the highest (0.97±0.48) compared with the other groups. The glomerulosclerosis index in the GSO group was 0.75±0.56, the GIRI group was 3.55±0.61, and the GSIM group was 2.08±1.37. There was a significant difference in the glomerulosclerosis index between the GSO and GIRI groups, but there was no significant difference between the GIRI and GSIM groups. These differences include the formation of sclerosis in the glomerulus, capillary loop, and synechiae.CONCLUSION: Simvastatin improves kidney function and glomerulosclerosis in I/R injury.KEYWORDS: ischemic-reperfusion injury, simvastatin, glomerulosclerosis

Abstract

BACKGROUND: C-C motif Ligand 7 (CCL7) has been reported to be associated with asthma severity in humans. Cynomolgus macaques (Macaca fascicularis; Mf) are often used as animal model of asthma but little is known about Mf genetic profile such as polymorphism. Our aim was to identify CCL7 polymorphism in Mf as a potential surrogate marker for identification of allergen responsiveness in the Mf model of asthma.METHODS: Real-time PCR was performed on archive of bronchoalveolar fluid samples previously collected from Mf that were exposed to allergen. Expression of CCL7 mRNA was evaluated, and sequencing technique was used to identify polymorphism in this gene.RESULTS: The results showed that CCL7 expression did not differ between Mf, despite a trend of lower expression in Mf that exhibited high response to allergen. By direct DNA sequencing of CCL7, 10 sequence variants were identified; three in promoter region (-460 G/A, -459 A/G, -456 -/A ), two in exon 1 (9 A/G, 65 G/C), four in intron 1 (135 T/C, 254 T/C, 420 T/C, 453 A/G), and one in intron 2 (1205 T/A).CONCLUSION: There was an association between Mf sensitivity to allergen with CCL7 promoter polymorphism at (-456 -/A). These results suggest that CCL7 may be a potential genetic marker to identify Mf sensitivity to allergen, which could be a useful tool to efficiently select for Mf model of asthma.KEYWORDS: asthma, CCL7, allergy, Ascaris suum, nonhuman primate

Abstract

BACKGROUND: Cancer stem cells (CSCs) eradication might serve as a robust approach for cancer eradication. MCF-7 as breast cancer continuous cell line is known to contain breast CSCs (BCSCs) for its capability to maintain its original tumor population. CSCs enriched culture is a fundamental tool for CSCs targeted therapy development. Effective and unsophisticated CSCs dedifferentiation protocol for producing CSCs enriched culture is needed.METHODS: MCF-7 cells were cultured initially in Dulbecco's Modified Eagle Medium (DMEM) low glucose medium then changed to DMEM:F12. Serum starvation was performed during each medium refreshment gradually with fetal bovine serum (FBS) concentration of 10%, 5%, 2.5% until reaching 1% FBS concentration. Stable MCF-7 culture was then adapted to serum free culture system, containing DMEM:F12, epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and B27 supplement as dedifferentiation protocol for 18 days. Cluster of differentiation (CD)44 and CD24 double staining immunocytochemistry was performed to evaluate cell stemness.RESULTS: The population of cells expressing BCSCs markers (CD44+/CD24low) in non-adherent single cells subpopulation was significantly increased after the dedifferentiation procedure (70.39%) compared to control groups (0.71%) (p<0.05). In contrast, the expression of BCSCs marker in adherent single cells subpopulation and for both adherent and non-adherent mammosphere the BCSCs markers showed a stable expression.CONCLUSION: BCSCs enrichment of breast cancer cell cultures from MCF-7 breast cancer cell line can be performed. Breast cancer cell plasticity is observed during the dedifferentiation protocol. Development of dedifferentiation inducing protocols can serve as an important foundation for breast cancer therapy development through BCSCs elimination.KEYWORDS: breast neoplasms, cell line, dedifferentiation, immunohistochemistry, neoplastic stem cells

Abstract

BACKGROUND: Vitamin D plays essential role in the regulation of inflammation, such as in pathogenesis of Juvenile Idiopathic Arthritis (JIA). Vitamin D deficiency has been reported among JIA patients, but there were conflicting results regarding the correlation with disease activity. This study aimed to assess vitamin D serum level and its correlation with C-Reactive Protein (CRP) and disease activity in JIA patients.METHODS: Children who were diagnosed with JIA according to International League of Associations for Rheumatology (ILAR) criterias were enrolled as JIA group subjects, while age and sex-matched healthy children were enrolled as the control group subjects. Vitamin D and CRP serum level were measured. Disease activity of JIA patients was calculated by Juvenile Arthritis Disease ActivityScore-27 (JADAS-27).RESULTS: Vitamin D serum level was lower in the JIA group compared to the healthy control group (p=0.000). Among 26 JIA patients, 61.5% were deficient, 30.8% were insufficient, and 7.7% had normal vitamin D. No significant different in CRP level between vitamin D group (p=0.441), but there was significant different in JADAS-27 (p=0.001). The mean of CRP and JADAS-27 were found highest in vitamin D deficiency group. Vitamin D serum level was negatively correlate with CRP (p=0.021, r=-0.452) and JADAS-27 (p=0.001 r=-0.595).CONCLUSION: Low level of vitamin D in JIA patients was inversely related to higher CRP and disease activity,suggesting that vitamin D supplementation could be havepotential role in JIA treatment.KEYWORDS: vitamin D, CRP, disease activity,JADAS-27, JIA

Abstract

BACKGROUND: The access to safe drinkingwater is increasingly difficult, especially in water catchment or coastal areas. Due to the difficulty, people in coastal areas tend to consume ready-to-use refilled drinking-water. However, the sanitation facilities on most drinking-water refill depots do not meet the requirements, hence really prone to microbial contamination. We conducted this study to determine the types of bacteria causing the contamination of refilled drinking-water from refill depots in Abeli, a coastal area in Kendari.METHODS: Samples were collected from all 6 drinkingwater refill depots in Abeli. Three-series fermentation tubes were used for the microbiological test, including the presumptive, confirmative and completed tests. The biochemical test was performed with indole test, methyl red test, Voges-Proskauer test, and citrate utilization test (IMViC) methods and the triple sugar iron agar (TSIA) test.RESULTS: Among 6 refilled drinking-water samples, we found the growth of coliform bacterial colonies in 3 samples, exhibiting various characteristics. Based on the characteristics, both microbiological and biochemical, the identified bacteria were Proteus sp., Escherichia coli and Klebsiella oxytoca.CONCLUSION: Bacteria that contaminated refilled drinking-water in Abeli were Proteus sp., E. coli and K. oxytoca. Continuous supervision is required to ensure the quality of water from drinking-water refill depots.KEYWORDS: bacteria, Proteus sp., Escherichia coli, Klebsiella oxytoca, coastal areas, refilled drinking water

Abstract

BACKGROUND: Carbohydrate antigens 15-3 (CA 15-3) is a conventional tumor marker in breast cancer, with low sensitivity and specificity. MicroRNA (miRNA)-21 showed its stability in circulation and could serve as powerful biomarker. The aim of this study was to evaluate miRNA-21 as breast cancer biomarker compared to CA 15-3 in Indonesian population.METHODS: Circulating plasma miRNA-21 expression was measured using qRT-PCR in 49 patients at various stages of breast cancer and 16 healthy controls. The relative expression value of miRNA-21 was calculated using 2-ΔΔCt. Meanwhile, CA 15-3 was quantified using electrochemiluminescence immunoassay (ECLIA) methods. The results of miRNA-21 and CA 15-3 plasma circulating expression were compared with controls at each stage and between stages of breast cancer.RESULTS: CA 15-3 median level in breast cancer group was 1.60 times higher compared to control group (p=0.019), 21.00 m/mL and 13.05 m/mL, respectively. Median miRNA-21 expression in breast cancer group was elevated 4.92 folds compared to control group (p=0.001), 4.43 and 0.90, respectively. There was no significant difference of CA 15-3 level between controls and all stages of breast cancer group. CA 15-3 cut-off value was 15.05 m/mL (p=0.016) with 59.2% sensitivity and 62.5% specificity. Meanwhile, there was a significant difference of miRNA-21 expression between controls and most stages of breast cancer group. Circulating miRNA-21 expression cut-off value was 2.07 (p=0.000) with 91.8% sensitivity and 87.5% specificity.CONCLUSION: Circulating miRNA-21 expression and CA 15-3 levels were significantly increased in breast cancer group compared to control group. The miRNA-21 expression increased consistently with breast cancer stage progression. miRNA-21 could serve as superior biomarker compared to CA 15-3.KEYWORDS: biomarker, breast cancer, circulating plasma, liquid biopsy, miRNA-21

Abstract

BACKGROUND: Obesity has been decades become a highly interest study, accompanied by the realization that adipose tissue (AT) plays a major role in the regulation of metabolic function.CONTENT: In past few years, adipocytes classification, development, and differentiation has been significant changes. The white adipose tissue (WAT) can transform to a phenotype like brown adipose (BAT) type and function. Exercise and cold induction were the most common factor for fat browning; however batokines such as fibroblast growth factor (FGF)-21, interleukin (IL)-6, Slit homolog 2 protein (SLIT2)-C, and Meteorin-like protein (METRNL) perform a beneficial browning action by increasing peroxisome proliferator-activated receptor gamma coactivator (PGC)-1α protein levels, a key factor to stimulate mitochondrial biogenesis and uncoupling Protein 1 (UCP1) transcription, thus change the WAT phenotype into beige.SUMMARY: AT recently known as a complex organ, not only bearing a storage function but as well as the master regulator of energy balance and nutritional homeostasis; brown and beige fat express constitutively high levels of thermogenic genes and raise our expectation on new strategies for fighting obesity and metabolic disorders.KEYWORDS: obesity, white adipose tissue, brown adipose tissue, beige adipose tissue, inflammation, IR, metabolic disease
