Abstract

BACKGROUND: Age contributes to body composition alteration, rises a common disorder in elderly known as sarcopenic obesity (SO), which is characterized by the combination of obesity (excess fat mass) and sarcopenia (reduced skeletal muscle mass) clinical form and function.CONTENT: The primary cause of SO is insulin resistance. Glucose transporter 4 (GLUT4) dysfunction results in impaired fatty acids oxidation. Decreased muscle mass results in lower mitochondria number and volume. Both will increase oxidative stress. Together with altered myokines in SO, oxidative stress was promoted and lead to higher M1 macrophages and failure in autophagy. The pro-inflammatory condition and dysbiosis links SO to a variety of cardiometabolic conditions, including non-alcoholic fatty liver disease, type 2 diabetes, and cardiovascular disease. The mortality, comorbidities, cardiometabolic diseases, and disability or impairment of SO is higher compare to obesity or sarcopenia alone. Some treatments have been developed for SO including adequate dietary intake, vitamin D and antioxidant supplementation, and exercises.SUMMARY: SO is more prevalent among the elderly and has a significant negative impact on their quality of life. Therefore, maintaining muscle mass and strength as well as preventing obesity should be the key goals of initiatives to support healthy aging.KEYWORDS: aging, body composition, obesity, sarcopenia, skeletal muscle, metabolic syndrome

Abstract

BACKGROUND: Malnutrition is a global health concern that results in changes in nutritional status, as indicated by alterations in phenotypic markers, hematological and biochemical parameters, and increased susceptibility to infection, as shown by decreased interleukin (IL)-2 levels. Andrographolide, the active component of Andrographis paniculata, stimulates the immune system and exhibits antibacterial and antiviral activity. Therefore, A. paniculata may serve as a potential adjuvant therapy for malnutrition. This study was conducted to analyze the effect of A. paniculata as an immunomodulator against malnutrition with characteristics of environmental enteric dysfunction (EED) and a low-protein diet by examining phenotypic markers, hematological, biochemical, and IL-2 levels.METHODS: Forty-five male Wistar rats were divided into seven groups. They were fed either a standard or a low-protein diet before receiving oral administration of various concentrations of A. paniculata leaf extract (APLE). APLE was administered 21 days after the initial low-protein diet. Hematological, biochemical, and phenotypic markers were assessed to determine the nutritional status of the rats. The protective effects of APLE were evaluated by measuring IL-2 levels using enzyme-linked immunosorbent assay (ELISA).RESULTS: Malnourished rats exhibited slow body growth, physical and behavioral changes, reduced leukocyte count, total protein, albumin, cholesterol, and villi length. Malnourished rats treated with APLE showed a more effective and significant increase in IL-2 levels, with higher concentrations of APLE resulting in higher IL-2 levels.CONCLUSION: APLE, in a concentration-dependent manner, can increase IL-2 levels, suggesting that APLE may have potential protective effects in a rat model of malnutrition.KEYWORDS: Andrographis paniculata, environmental enteric dysfunction, interleukin (IL)-2, low protein, malnutrition

Abstract

BACKGROUND: Neoadjuvant chemotherapy (NAC) plays a crucial role in the management of invasive breast cancer with no special type (IBC-NST), with the immune system's response to cancer heavily relying on the dynamics between tumor-infiltrating lymphocytes (TILs) and cancer cells. In this study, the differential effects of anthracycline-based NAC on stromal and intratumoral foxhead box P3 (FOXP3+) TILs expressions were specifically examined.METHODS: In this cross-sectional study, 32 IBC-NST samples were evaluated for pre- and post-NAC FOXP3+ TIL expression as well as the changes of FOXP3+ TIL expression. Comprehensive data collection regarding subjects' age, tumor size, grade, lymphovascular invasion, regional lymph node metastasis, and receptor status were conducted. Immunohistochemistry was utilized to quantify FOXP3+ TILs. The stromal, intratumoral and total FOXP3+ TILs expression were then analyzed.RESULTS: Significant reductions in FOXP3+ TIL expression post-NAC were observed, with stromal FOXP3+ TILs showing a median decrease of 3.6 units in subjetcs aged ≥50 years (p=0.013) and a median decrease of 13.2 units in subjects with tumors ≥5 cm after NAC (p=0.006). In contrast, intratumoral FOXP3+ TILs remained relatively stable, with minor changes. The total FOXP3+ TIL expression, combining stromal and intratumoral components, was significantly decreased with a median of 13.0 units decreased to 5.3 units (p<0.001).CONCLUSION: This study highlights the significant reduction in stromal FOXP3+ TIL expression after NAC treatment in IBC-NST subjects, in contrast to the relatively stable intratumoral FOXP3+ TILs. Understanding these differences may guide future therapeutic strategies and improve treatment outcomes for IBC-NST.KEYWORDS: biomarkers, chemotherapy, FOXP3, prognostic, response, lymphocyte

Abstract

BACKGROUND: The risk factors for intrauterine transmission of hepatitis B virus (HBV) in hepatitis B surface antigen (HBsAg)-positive pregnant women are poorly understood. Numerous factors are considered to be involved, including placental barrier, obstetric environment, high viral load, and positivity of hepatitis B e antigen (HBeAg). This study was conducted to investigate the role of placenta barrier, clinical, and viral factors in intrauterine transmission of HBV.METHODS: A cross-sectional study was conducted involving 1,353 pregnant women who underwent HBsAg screening. Eighty-four (6.2%) women were detected as HBsAg positive and were examined for HBsAg level, anti-HBs, anti-HBc, HBeAg/hepatitis B e antibody (anti-HBe) status, and HBV DNA presence in cord blood. Quantitative HBV DNA was analyzed using real-time polymerase chain reaction (PCR).RESULTS: Eighty-four of 1,353 subjects were HBsAg-positive. HBV DNA was positive in 28/84 (33.7%) maternal sera, 19/79 (24.05%) placental specimens, and 9/83 (10.84%) in cord blood. There were significant associations between HBV DNA in maternal serum (p=0.000) and placental tissue (p=0.000) with HBV DNA in the cord blood. No clinical factors were associated with HBV DNA transmission in cord blood. Sixty percent of viral load >5.3 log10 copies/mL were found in the cord blood, of which 43.8% HBeAg positive and 3.1% HBeAg negative.CONCLUSION: Reduced transmission via compartments established the placenta’s barrier function in mother-to-child transmission. A high maternal viral load and positive HBeAg were risk factors for intrauterine transmission, while negative HBeAg still has the possibility of transmission.KEYWORDS: mother-to-child transmission, hepatitis B virus, intrauterine

Abstract

BACKGROUND: Probiotics may modify the gut microbiome and have been proven to improve psoriasis vulgaris. Lactiplantibacillus plantarum IS-10506 is a probiotic strain of Indonesian origin. It offers a safe and effective probiotic for psoriasis patients in Indonesia. This study was conducted to evaluate the effect of L. plantarum IS-10506 on clinical and immunology markers in psoriasis vulgaris.METHODS: This randomized, placebo-controlled, and double-blind trial compared L. plantarum IS-10506 (2×1010 CFU/day) and placebo in 49 patients mild-moderate psoriasis vulgaris, which were divided into intervention (n=24) and control groups (n=25). The interventions were given twice daily for 12 weeks. Both groups received topical corticosteroid and emollient as standard treatment. Psoriasis area and severity index (PASI), dermatology life quality index (DLQI), interleukin (IL)-10, IL-17, and forkhead box protein (Foxp3) were then assessed.RESULTS: Mean PASI score for the the subjects in probiotic group was significantly reduced compared to placebo at week-6 (p=0.024), and was sustained until week-12 (p=0.049). At week-12, DLQI scores in the probiotic group were lower than placebo (7.57±5.77 vs. 7.79±5.48). IL-17 level was significantly decreased (p=0.013), while the IL-10 and Foxp3 were significantly increased (p≤0.001 and p=0.048, respectively) in probiotic group. Six months after the completion of study, subjects in probiotic group had a lower probability of flares (52.2%) compared to placebo (79.2%). Two subjects receiving probiotics and one receiving placebo noticed changes in defecation frequency, while another subject in the placebo group complained of mild nausea.CONCLUSION: L. plantarum IS-10506 might effectively improve clinical outcomes and immune biomarkers in psoriasis vulgaris patients, potentially acting as an adjuvant therapy.KEYWORDS: psoriasis, probiotic, clinical severity, immune marker, human and health

Abstract

BACKGROUND: Type 2 diabetes mellitus (T2DM) is the most common metabolic disorder associated with oxidative stress and chronic inflammation. Understanding the regulatory mechanisms related to the role of nuclear factor erythroid 2 (Nrf2), a master regulator of cellular antioxidant defenses, in individuals with T2DM, is essential. Therefore, in-depth investigation regarding the associations between Nrf2 levels, and metabolic parameters, such as waist circumference, fasting glucose levels, HbA1C, and serum inflammatory markers expressions is needed to elucidate the mechanisms driving T2DM and its metabolic disturbances.METHODS: This was a cross-sectional study including 90 T2DM and 25 healthy subjects. Nrf2 level; serum inflammatory markers levels, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, interferon (IFN)-α2, IFN-g, monocyte chemoattractant protein (MCP)-1, IL-10, IL-12p70, IL-17A, IL-18 and IL-23; as well as waist circumference; fasting glucose levels; and HbA1C were measured. Nrf2 concentrations in peripheral blood mononuclear cells were determined using enzyme-linked immunosorbent assay (ELISA), while serum inflammatory markers concentrations were quantified with flowcytometry.RESULTS: Nrf2, TNF-α, and IL-17A levels were significantly higher in the T2DM group, while IL-1β, IFN-α 2, IL-10, IL-12p70, and IL-23 levels were elevated in healthy controls Nrf2 exhibited positive correlations with waist circumference, fasting glucose, HbA1C, and TNF-α. Conversely, an inverse correlation of Nrf2 was observed with IL-1β, IL-12p70 and IL-17A.CONCLUSION: Correlations between Nrf2 and metabolic clinical parameters suggest its role in regulating glucose metabolism and adiposity. Elevated Nrf2 levels observed in T2DM patients may present novel therapeutic avenues for enhancing endogenous antioxidant defenses.KEYWORDS: type 2 diabetes mellitus, Nrf2, oxidative stress, inflammation, metabolic regulation, therapeutic strategies

Abstract

BACKGROUND: Early detection and management of lupus nephritis (LN) in systemic lupus erythematosus (SLE) are essential to prevent irreversible kidney damage and improve patient outcomes; therefore, identifying reliable biomarkers to predict LN is paramount. However, there are still relatively few studies examining the potential biomarkers for LN in SLE patients. This study was conducted to investigate serum deoxyribonuclease I (DNase), soluble tumor necrosing factor 1 (sTNFR1) and soluble tumor necrosing factor 2 (sTNFR2) as a risk factor for LN in SLE patients.METHODS: A case-control study involving SLE patients aged 20-60 years was conducted. Blood was withdrawn from each subject for the measurement of serum level of DNase1, sTNFR1, and sTNFR2 that was performed using enzyme-linked immunoassay (ELISA) methods. Data was then analyzed using Chi-Square test and logistic regression tests.RESULTS: A total of 22 patients with LN and 22 without LN were included. The cut-off value for DNase1, sTNFR1, and sTNFR2 were 5.05 ng/mL, 6.52 ng/mL, and 7.02 ng/mL, respectively. The risk factors of LN in SLE patients were the low level of serum DNase1 (aOR=6.64; 95%CI: 1.25-35.29; p=0.026), low level of serum sTNFR1 (aOR=8.12; 95% CI: 1.56-42.10; p=0.013), and low level of serum sTNFR2 (aOR=5.57; 95%CI: 1.03-30.11; p=0.046).CONCLUSION: Serum DNase1 lower than 5.05 ng/mL, sTNFR1 lower than 6.52 ng/mL, and sTNFR2 lower than 7.02 ng/mL were risk factors for lupus nephritis in SLE patients. Hence, serum DNase1, sTNFR1 and sTNFR2 could be used as risk factors predictors for LN in SLE patients.KEYWORDS: DNase1, sTNFR1, sTNFR2, SLE, lupus nephritis

Abstract

BACKGROUND: The cytokine chemokine ligand 16 (CXCL16) plays an important role in the pathophysiology of endometriosis by regulating the inflammatory response and contributing to the pain-associated endometriosis. Despite this, the impact of epigenetic modifications, such as DNA methylation, on CXCL16 has yet to be fully understood. Therefore, this research was conducted to assess both the mRNA expression and DNA methylation levels of the proinflammatory gene CXCL16 in the endometrium tissue and menstrual blood of patients with and without endometriosis.METHODS: Thirty-five women with and without endometriosis were involved in this research. Subjects' menstrual blood samples were collected using filter paper pads, meanwhile the endometrium tissue were collected by performing biopsy, from which DNA and RNA were extracted. The DNA methylation levels of the CXCL16 were measured using the pyrosequencing method following bisulfite conversion treatment. Meanwhile, the mRNA expression level was measured using the quantitative polymerase chain reaction (qPCR) method and analyzed with the Livak method.RESULTS: The mRNA expression of CXCL16 in menstrual blood of endometriosis subjects was 2.42 times higher compared to control group (p=0.030). Furthermore, the expression of CXCL16 in menstrual blood was identical to that in endometrial tissue (p=0.173). DNA methylation analysis showed that CXCL16 in the menstrual blood of endometriosis subjctes had lower methylation levels compared to controls (p=0.004), indicating hypomethylation.CONCLUSION: Increased mRNA expression and hypomethylation of CXCL16 in the menstrual blood of endometriosis patients could serve as a direct marker for diagnosing endometriosis. However, further study to validate these findings and explore the potential of CXCL16 as a diagnostic tool, and additional research involving larger patient for the cohorts study is necessary.KEYWORDS: CXCL16, DNA methylation, endometrium, menstrual blood, mRNA expression, pain

Abstract

BACKGROUND: Type 2 Diabetes (T2D) impairs the innate immune system including monocytes. Monocytes are divided into two subgroups depending on the expression of cluster of differentiation (CD)14 and CD16 receptors, namely CD14+CD16- and CD14+CD16+. CD14+CD16+ are proinflammatory monocytes and develop into M1 type macrophages, which contribute to foam cell production, a risk factor for cardiovascular disease (CVD). Therefore, it is important to determine the influence of T2D conditions on changes in monocyte subsets and whether these changes correlate with CVD risk markers.METHODS: Peripheral blood mononuclear cell (PBMC) was obtained from 10 T2D subjects and 10 healthy donors. Subsequently, PBMC was incubated for 24 hours with and without 10 mL lipopolysaccharide. Flow cytometry was used to evaluate CD14 and CD16 expression, while multiplex immunoassays were applied to measure interleukin (IL)-1b and IL-10 concentrations in supernatants.RESULTS: In T2D, the percentage of CD14+CD16+ monocytes increased (p=0.07), and an increase in CD14+CD16+ monocytes more than 6.8% was linked with CVD risk markers (r=10.146, p=0.002). Meanwhile, inflammatory mediators released by monocytes shown an increase in IL-1b (p=0.041) but not in IL-10 (p=0.082) in T2D subjects. Fasting blood glucose levels were also found to be substantially linked with an increase in CD14+CD16+ monocytes (r=0.530, p=0.016).CONCLUSION: T2D patients had a higher percentage of CD14+CD16+ monocytes and IL-1b levels than healthy donors. An increase in CD14+CD16+ monocytes above 6.8% associated with CVD risk markers in T2D patients.KEYWORDS: type 2 diabetes, monocytes, CD14, CD16, cardiovaskular disease risk marker

Abstract

BACKGROUND: The need for clinically useful biomarkers which can predict the surgical outcome after primary debulking surgery (PDS) in patients with advance ovarian cancer (AOC) is really important. Insulin-like growth factor-binding protein 2 (IGFBP2) is the main binding protein expressed by ovarian cancer cells, which plays a prominent role in promoting proliferation, driving invasion, and suppressing apoptosis. This study was conducted to assess the performance of IGFBP2 in predicting the surgical outcome after PDS in patients with AOC.METHODS: Twenty-four subjects with AOC (Stage IIIc/IV) who underwent PDS were recruited consecutively. Clinicopathologic data were obtained from subjects' medical records. Blood samples were withdrawn form each subject and preoperative level of IGFBP2 were measured using enzyme-linked immunosorbent assay (ELISA). Multivariate analysis was employed to test the performance of multiple predictors of surgical outcome.RESULTS: Eighteen patients (75%) had suboptimal outcome after PDS. Mean IGFBP2 level was significantly higher in the suboptimal group (1157.5±359.9 ng/mL vs. 679.1±504.5 ng/mL, p=0.018). In bivariate model, higher preoperative level of IGFBP2 predict the suboptimal outcome with good accuracy (AUC: 0.796, sensitivity: 83.3%, specificity: 83.3%, p=0.033, optimal threshold level 870 ng/mL). Higher IGFBP2 level was associated with higher risk of suboptimal outcome, although IGFBP2 was not an independent risk factor (adjusted OR: 5.0, 95% CI: 0.43-57.9, p=0.198).CONCLUSION: IGFBP2 is a novel and promising biomarker for surgical outcome prediction following PDS in AOC patients. Since it is predictive for suboptimal outcome, patients with higher preoperative level of IGFBP2 needs more thorough preoperative evaluation as well as meticulous surgical technique to optimize the surgical outcome.KEYWORDS: IGFBP2, advance ovarian cancer, PDS, surgical outcome, predictor
