Associations between demographic factors, clinical variables, social determinants of health, vaccine hesitancy, vaccine behavior, and revaccination status: A survey of adult HCT survivors in the United States.

BACKGROUND: Comprehensive survivorship care after hematopoietic cell transplantation (HCT) includes revaccination to restore immunity to vaccine-preventable diseases (VPDs). There is complexity to revaccination in this setting, and revaccination rates are sub-optimal. HCT survivors are at high-risk for morbidity and mortality from infections including VPDs, underscoring the importance of interventions to improve revaccination rates among survivors. Determining associations between survivor characteristics and revaccination uptake may guide interventions. OBJECTIVES: The overall study objective was to advance our understanding of factors influencing revaccination uptake among adult HCT survivors living in the U.S. The specific study aims were to: 1) determine the prevalence of adult survivors who are completely, partially, or not revaccinated at 2-8 years after HCT and 2) examine associations between demographic variables, social determinants of health, clinical variables, past vaccination behaviors, vaccine hesitancy (Vaccination Confidence Scale), and revaccination status in adult HCT survivors. STUDY DESIGN: This study employed a one-time cross-sectional revaccination survey of adults who were surviving 2-8 years after HCT and living in the U.S. The survey was sent to eligible survivors in the Fred Hutchinson Cancer Center Long-term Follow-up research cohort. The point prevalence of revaccination outcomes was determined from all the respondents (n=338), differences in intent to revaccinate for people not yet fully revaccinated were explored using Fisher's exact test (n=126), and associations were examined between revaccination outcomes and predictors using multivariable logistic regression (n=292). RESULTS: Survey response rate was 30%. Among respondents, 62% were completely revaccinated, 33% were partially revaccinated, and 4% were not revaccinated. Most respondents (77%) who were not yet fully revaccinated planned to complete the revaccination protocol. However, fewer not-revaccinated respondents than partially revaccinated respondents planned to complete revaccination (50% vs 80%, p=0.032). Factors associated with incomplete revaccination were shorter time from HCT, inadequate immune reconstitution, and not having received all childhood vaccines as a child. CONCLUSIONS: Our analysis has identified multiple variables associated with revaccination outcomes, indicating the potential for interventions to enhance post-HCT revaccination rates. Since many survivors cannot be revaccinated promptly due to delayed immune recovery, clinicians should iteratively re-evaluate for revaccination readiness as long as it takes to ensure eventual revaccination. Broader efforts by the healthcare community to increase childhood vaccine uptake might eventually support revaccination uptake. Future research that builds on these findings should focus on intervention testing.

Rational Design of High-Efficiency Synthetic Small Regulatory RNAs and Their Application in Robust Genetic Circuit Performance Through Tight Control of Leaky Gene Expression.

Synthetic sRNAs show promise as tools for targeted and programmable gene expression manipulation. However, the design of high-efficiency synthetic sRNAs is a challenging task that necessitates careful consideration of multiple factors. Therefore, this study aims to investigate rational design strategies that significantly and robustly enhance the efficiency of synthetic sRNAs. This is achieved by optimizing the following parameters: the sRNA scaffold, mRNA binding affinity, Hfq protein expression level, and mRNA secondary structure. By utilizing optimized synthetic sRNAs within a positive feedback circuit, we effectively addressed the issue of gene expression leakage─an enduring challenge in synthetic biology that undermines the reliability of genetic circuits in bacteria. Our designed synthetic sRNAs successfully prevented gene expression leakage, thus averting unintended circuit activation caused by initial expression noise, even in the absence of signal molecules. This result shows that high-efficiency synthetic sRNAs not only enable precise gene knockdown for metabolic engineering but also ensure the robust performance of synthetic circuits. The strategies developed here hold significant promise for broad applications across diverse biotechnological fields, establishing synthetic sRNAs as pivotal tools in advancing synthetic biology and gene regulation.

Decreasing Chronic Graft-Versus-Host Disease rates in all populations.

Since 2005 there has been steady decline in chronic graft-versus-host disease (cGVHD) at Fred Hutchinson Cancer Center (FHCC). To better understand this phenomenon, we studied the risk of cGVHD requiring systemic immunosuppression (cGVHD-IS) as a function of hematopoietic cell transplantation (HCT)-date in 3066 survivors from 2005 through 2019. Cox regression models were fit to assess associations of HCT-date (as a continuous linear variable) with cause-specific hazards of cGVHD, using unadjusted and adjusted models. Median follow-up for study subjects was 7.0 years (range, 1.0-17.2). Two-year probabilities of cGVHD-IS declined among all survivors from 45-52% (2005-2007) to approximately 40% (2008-2012) and then further to ~26% by 2017. A decline was also observed when the analysis was restricted to 502 pediatric survivors, with cGVHD-IS probabilities being <10% since 2013. Among 305 adult and pediatric survivors who were transplanted for nonmalignant diseases, cGVHD rates showed greater fluctuation but remained <20% after 2016. Each 5-year increase in HCT-date was associated with a 27% decrease in the cause-specific hazard of cGVHD (unadjusted hazard ratio [HR] 0.73; 95% confidence interval [CI] 0.68-0.78, p<.0001); the HR was 0.81 (95% CI 0.75-0.87, p<.0001) even after adjusting for various factors (age, donor/stem-cell source, race, sex, conditioning intensity, GVHD prophylaxis, among others) that could lead to cGVHD reduction. The decline in cGVHD was not fully explained by demographic shifts and greater use of HCT approaches generally associated with lower cGVHD rates. This observation underscores that single-cohort cGVHD-prevention studies should use contemporaneous and not historical controls for comparisons.

Autoinhibited Protein Database: a curated database of autoinhibitory domains and their autoinhibition mechanisms.

Autoinhibition, a crucial allosteric self-regulation mechanism in cell signaling, ensures signal propagation exclusively in the presence of specific molecular inputs. The heightened focus on autoinhibited proteins stems from their implication in human diseases, positioning them as potential causal factors or therapeutic targets. However, the absence of a comprehensive knowledgebase impedes a thorough understanding of their roles and applications in drug discovery. Addressing this gap, we introduce Autoinhibited Protein Database (AiPD), a curated database standardizing information on autoinhibited proteins. AiPD encompasses details on autoinhibitory domains (AIDs), their targets, regulatory mechanisms, experimental validation methods, and implications in diseases, including associated mutations and post-translational modifications. AiPD comprises 698 AIDs from 532 experimentally characterized autoinhibited proteins and 2695 AIDs from their 2096 homologs, which were retrieved from 864 published articles. AiPD also includes 42 520 AIDs of computationally predicted autoinhibited proteins. In addition, AiPD facilitates users in investigating potential AIDs within a query sequence through comparisons with documented autoinhibited proteins. As the inaugural autoinhibited protein repository, AiPD significantly aids researchers studying autoinhibition mechanisms and their alterations in human diseases. It is equally valuable for developing computational models, analyzing allosteric protein regulation, predicting new drug targets, and understanding intervention mechanisms AiPD serves as a valuable resource for diverse researchers, contributing to the understanding and manipulation of autoinhibition in cellular processes.

Genomic characterization of Aeromonas spp. isolates from striped catfish with motile Aeromonas septicemia and human bloodstream infections in Vietnam.

Aeromonas spp. are commonly found in the aquatic environment and have been responsible for motile Aeromonas septicemia (MAS) in striped catfish, resulting in significant economic loss. These organisms also cause a range of opportunistic infections in humans with compromised immune systems. Here, we conducted a genomic investigation of 87 Aeromonas isolates derived from diseased catfish, healthy catfish and environmental water in catfish farms affected by MAS outbreaks in eight provinces in Mekong Delta (years: 2012-2022), together with 25 isolates from humans with bloodstream infections (years: 2010-2020). Genomics-based typing method precisely delineated Aeromonas species while traditional methods such as aerA PCR and MALDI-TOF were unable identify A. dhakensis. A. dhakensis was found to be more prevalent than A. hydrophila in both diseased catfish and human infections. A. dhakensis sequence type (ST) 656 followed by A. hydrophila ST251 were the predominant virulent species-lineages in diseased catfish (43.7 and 20.7 %, respectively), while diverse STs were found in humans with bloodstream infections. There was evidence of widespread transmission of ST656 and ST251 on striped catfish in the Mekong Delta region. ST656 and ST251 isolates carried a significantly higher number of acquired antimicrobial resistance (AMR) genes and virulence factors in comparison to other STs. They, however, exhibited several distinctions in key virulence factors (i.e. lack of type IV pili and enterotoxin ast in A. dhakensis), AMR genes (i.e. presence of imiH carbapenemase in A. dhakensis), and accessory gene content. To uncover potential conserved proteins of Aeromonas spp. for vaccine development, pangenome analysis has unveiled 2202 core genes between ST656 and ST251, of which 78 proteins were in either outer membrane or extracellular proteins. Our study represents one of the first genomic investigations of the species distribution, genetic landscape, and epidemiology of Aeromonas in diseased catfish and human infections in Vietnam. The emergence of antimicrobial resistant and virulent A. dhakensis strains underscores the needs of enhanced genomic surveillance and strengthening vaccine research and development in preventing Aeromonas diseases in catfish and humans, and the search for potential vaccine candidates could focus on Aeromonas core genes encoded for membrane and secreted proteins.

Returning to Work Following Hematopoietic Cell Transplantation: The Survivor's Perspective.

While curing a patient's underlying disease is the primary goal of physicians performing hematopoietic cell transplantation (HCT), the ultimate objective is to provide patients with optimal post-HCT quality of life. For many survivors, this includes returning to work (RTW). We conducted a survey of 1- to 5-yr post-HCT survivors at our center to evaluate their perspective on facilitators and barriers to RTW as well as to gauge interest in potentially useful RTW support interventions. Survivors aged 18 to 65 yrs (n = 994) were sent an annual survey that included 36 supplementary questions about post-HCT RTW. Survey questions were selected from published national cancer survivor surveys and then modified specifically for HCT survivors. Three hundred forty-four (35%) survivors with a mean age of 53 yrs completed the survey, of whom 272 (79%) had worked prior to their diagnosis. Of those 272 patients, 145 (53%) were working currently and another 22 (8%) had attempted to go back to work following HCT but were not presently working. We found that having had an allogeneic versus autologous HCT (P = .006) was associated with a decreased likelihood of currently working, whereas frequent employer communication (>once a month) (P = .070) and having a more supportive employer (P = .036) were associated with a greater chance of currently working. Of survivors currently working, 45% reported that they had made one or more changes to their work schedule (e.g., flexible schedule or part-time work) or environment (e.g., work from home) upon RTW. Ninety-five percent of responders reported that they could have benefited from RTW support provided by the transplant center, but only 13% indicated that they had received it. Education on RTW challenges, information on disability benefits, and access to physical therapy were among the most requested support interventions. To improve post-HCT quality of life for survivors open to assistance, providers should address work status and goals, recognize barriers to successful return, and offer RTW support including working directly with employers. Allogeneic HCT survivors are particularly vulnerable to failing attempts to RTW and should be the target of retention interventions. A previously published manuscript on RTW guidance for providers of stem cell transplant patients endorsed by the American Society of Transplant and Cellular Therapy is available in Open Access and can be used as a tool to counsel and support these patients.

The genetic landscape of chromosomal aberrations in 3776 Vietnamese fetuses with clinical anomalies during pregnancy.

Background: Copy number variation sequencing (CNV-seq) is a powerful tool to discover structural genomic variation, but limitations associated with its retrospective study design and inadequate diversity of participants can be impractical for clinical application. Aim: This study aims to use CNV-seq to assess chromosomal aberrations in pregnant Vietnamese women. Materials & methods: A large-scale study was conducted on 3776 pregnant Vietnamese women with abnormal ultrasound findings. Results: Chromosomal aberrations were found in 448 (11.86%) women. Of these, 274 (7.26%) had chromosomal aneuploidies and 174 (4.61%) carried pathogenic/likely pathogenic CNVs. Correlations were established between chromosomal aberrations and various phenotypic markers. Conclusion: This comprehensive clinical study illuminates the pivotal role of CNV-seq in prenatal diagnosis for pregnancies featuring fetal ultrasound anomalies.

Financial Toxicity, Time Toxicity, and Quality of Life in Multiple Myeloma.

BACKGROUND: Patients with multiple myeloma (MM) may be on therapy for years, which can lead to financial toxicity (FinTox) or time toxicity (TimeTox). The prevalence, predictors, and quality of life (QOL) impacts of FinTox and TimeTox during different phases of MM treatment have not been characterized. PATIENTS AND METHODS: We conducted a single-center cross-sectional survey of patients with MM who had undergone transplantation. FinTox+ was defined as a COST-FACIT score <23, TimeTox+ as MM-related interactions (including phone calls) ≥1x weekly or ≥1x monthly in-person among far-residing patients, QOL using PROMIS Global Health, and functional status using patient-reported Karnofsky performance status (KPS). RESULTS: Of 252 patients, 22% and 40% met FinTox+ and TimeTox+ criteria respectively. Respective FinTox+ and TimeTox+ proportions were 22%/37% for patients on maintenance, 22%/82% with active therapy, and 20%/14% with observation. FinTox+ predictors included annual income (P < .01) and out-of-pocket costs (P < .01). TimeTox+ predictors included disease status (P < .001), caregiver status (P = .01), far-residing status (P < .001), and out-of-pocket costs (P = .03). FinTox+ was associated with a clinically meaningful decrease in mental QOL, while TimeTox+ patients were more likely to have KPS ≤ 80. CONCLUSIONS: In our large study, monetary status but not disease status predicted FinTox. Over a third of patients on maintenance reported TimeTox. FinTox+ was associated with decreased mental health, while TimeTox+ was associated with worse performance status. These two toxicities may negatively impact patient wellbeing, and studies of strategies to mitigate their impact are in development.

Sporadic Pemphigus Foliaceus in a 3-Year-Old Vietnamese Girl: A Case Report and Literature Review.

Pemphigus foliaceus is an uncommon autoimmune intraepidermal blistering disease characterized by immunoglobulin (Ig) G autoantibodies that attack desmoglein-1 in the epidermis. There are two predominant forms of pemphigus foliaceus, sporadic and endemic. Sporadic pemphigus foliaceus is known to be more prevalent in middle-aged and elderly people and to be extremely rare in children. Less than 40 nonendemic pediatric pemphigus foliaceus cases have been documented in the literature. This report documents a case of sporadic pemphigus foliaceus in a 3-year-old Vietnamese girl who presented with generalized scaling and crusted erosions over the body.

Targeted Radiation Delivery before Haploidentical HCT for High-risk Leukemia or MDS Patients Yields Long-term Survivors.

PURPOSE: Hematopoietic cell transplantation (HCT) has curative potential for myeloid malignancies, though many patients cannot tolerate myeloablative conditioning with high-dose chemotherapy alone or with total-body irradiation (TBI). Here we report long-term outcomes from a phase I/II study using iodine-131 (131I)-anti-CD45 antibody BC8 combined with nonmyeloablative conditioning prior to HLA-haploidentical HCT in adults with high-risk relapsed/ refractory acute myeloid or lymphoid leukemia (AML or ALL), or myelodysplastic syndrome (MDS; ClinicalTrials.gov, NCT00589316). PATIENTS AND METHODS: Patients received a tracer diagnostic dose before a therapeutic infusion of 131I-anti-CD45 to deliver escalating doses (12-26 Gy) to the dose-limiting organ. Patients subsequently received fludarabine, cyclophosphamide (CY), and 2 Gy TBI conditioning before haploidentical marrow HCT. GVHD prophylaxis was posttransplant CY plus tacrolimus and mycophenolate mofetil. RESULTS: Twenty-five patients (20 with AML, 4 ALL and 1 high-risk MDS) were treated; 8 had ≥ 5% blasts by morphology (range 9%-20%), and 7 had previously failed HCT. All 25 patients achieved a morphologic remission 28 days after HCT, with only 2 patients showing minimal residual disease (0.002-1.8%) by flow cytometry. Median time to engraftment was 15 days for neutrophils and 23 days for platelets. Point estimates for overall survival and progression-free survival were 40% and 32% at 1 year, and 24% at 2 years, respectively. Point estimates of relapse and nonrelapse mortality at 1 year were 56% and 12%, respectively. CONCLUSIONS: 131I-anti-CD45 radioimmunotherapy prior to haploidentical HCT is feasible and can be curative in some patients, including those with disease, without additional toxicity.

A cohort-based study of host gene expression: tumor suppressor and innate immune/inflammatory pathways associated with the HIV reservoir size.

The major barrier to an HIV cure is the HIV reservoir: latently-infected cells that persist despite effective antiretroviral therapy (ART). There have been few cohort-based studies evaluating host genomic or transcriptomic predictors of the HIV reservoir. We performed host RNA sequencing and HIV reservoir quantification (total DNA [tDNA], unspliced RNA [usRNA], intact DNA) from peripheral CD4+ T cells from 191 ART-suppressed people with HIV (PWH). After adjusting for nadir CD4+ count, timing of ART initiation, and genetic ancestry, we identified two host genes for which higher expression was significantly associated with smaller total DNA viral reservoir size, P3H3 and NBL1, both known tumor suppressor genes. We then identified 17 host genes for which lower expression was associated with higher residual transcription (HIV usRNA). These included novel associations with membrane channel (KCNJ2, GJB2), inflammasome (IL1A, CSF3, TNFAIP5, TNFAIP6, TNFAIP9, CXCL3, CXCL10), and innate immunity (TLR7) genes (FDR-adjusted q<0.05). Gene set enrichment analyses further identified significant associations of HIV usRNA with TLR4/microbial translocation (q = 0.006), IL-1/NRLP3 inflammasome (q = 0.008), and IL-10 (q = 0.037) signaling. Protein validation assays using ELISA and multiplex cytokine assays supported these observed inverse host gene correlations, with P3H3, IL-10, and TNF-α protein associations achieving statistical significance (p<0.05). Plasma IL-10 was also significantly inversely associated with HIV DNA (p = 0.016). HIV intact DNA was not associated with differential host gene expression, although this may have been due to a large number of undetectable values in our study. To our knowledge, this is the largest host transcriptomic study of the HIV reservoir. Our findings suggest that host gene expression may vary in response to the transcriptionally active reservoir and that changes in cellular proliferation genes may influence the size of the HIV reservoir. These findings add important data to the limited host genetic HIV reservoir studies to date.

Preliminary Consequences of Blood Pressure Management and Blood Homocysteine Levels with Perindopril in Newly Diagnosed Hypertensive Patients in the Vietnamese Population.

Background: Perindopril is an ACE inhibitor that aids in both blood pressure regulation and homocysteine reduction. Objectives: Our study aimed to evaluate the results of controlling blood pressure and blood homocysteine levels by perindopril in patients with primary hypertension. Materials and Methods: A cross-sectional descriptive study with a longitudinal follow-up was conducted on 105 primary hypertensive patients treated with perindopril. Results: The results of our study showed that after 6 weeks of treatment with perindopril, the proportion of patients with the target blood pressure (BP) level accounted for 70.5%, the rate of grade 1 hypertension decreased from 61.0% to 25.7%, grade 2 blood pressure decreased from 17.1% to 3.8%, and there was no case of grade 3 hypertension. At the same time, we also found that the rate of BP control in the group of patients who controlled Hcy below a threshold of 15 µmol/L was significantly higher than in the other group (p < 0.05). Concerning the efficacy of decreasing homocysteine in blood, we discovered that after 6 weeks of treatment with perindopril, the proportion of patients with elevated homocysteine reduced considerably from 74.3% to 40% (p < 0.05). In addition, the homocysteine concentration was 4.33 mol/L lower after treatment than before treatment (95% CI: 3.69-4.97) (p < 0.05). Conclusion: Perindopril helps control blood pressure and reduces blood homocysteine levels in patients with primary hypertension.

Adapting a clinical decision support system to improve identification of pediatric hypertension in a rural health system: Design of a pragmatic trial.

BACKGROUND: Identifying hypertension (HTN) early is crucial in preventing and lowering the long-term risk of heart disease, yet HTN in children often goes undiagnosed. An electronic health record linked, web-based clinical decision support (CDS) called PedsBP can help address this care gap and has been previously shown to increase recognition of HTN by primary care clinicians. OBJECTIVES: To adapt the PedsBP tool for use in a mostly rural health system and then to evaluate the effectiveness of PedsBP for repeat of hypertensive level blood pressure (BP) measurements and HTN recognition among youth 6-17 years of age in primary care settings, comparing low-intensity and high-intensity implementation approaches. METHODS AND DESIGN: PedsBP was evaluated through a pragmatic, clinic-randomized trial. The tool was piloted in 2 primary care clinics and modified prior to the full trial. Forty community-based, primary care clinics (or clusters of clinics) were randomly allocated in a 1:1:1 ratio to usual care, low-intensity implementation (CDS only), or high-intensity implementation (CDS plus in-person training, monthly use reports, and ongoing communication between study staff and clinics). Accrual of eligible patients started on August 1, 2022 and will continue for 18 months. Primary outcomes include repeating hypertensive level BP measurements at office visits and clinical recognition of HTN. Secondary outcomes include lifestyle counseling, dietician referral, and BP at follow-up. CONCLUSION: This report focuses on the design and feasibility of adapting and implementing PedsBP in a rural primary care setting. The trial and analysis are ongoing with main results expected in mid-2024.

Hematohidrosis induced by separation anxiety disorder during COVID-19 quarantine: a case report and brief literature review.

Here, we report a case involving a 10-year-old Vietnamese girl who developed hematohidrosis during the coronavirus disease quarantine. She was hospitalized with a 3-week recurrent bleeding on the abdominal skin. Physical examination revealed no signs of injuries on the skin. Hematological and biochemical test results and coagulation profiles were all within normal ranges. No abnormal findings were observed on abdominal ultrasonography and computed tomography. Numerous erythrocytes were observed during the microscopic examination of fluid samples from the abdominal skin. It was speculated that hematohidrosis was precipitated by separation anxiety disorder, because the onset and remission of symptoms correlated with the beginning and end of the local quarantine, respectively. Our case report and brief literature review highlight the transient and benign nature of hematohidrosis. Although specific guidelines are not well established, hematohidrosis is a transient phenomenon that is treatable with pharmaceutical and non-pharmaceutical interventions, and its overall prognosis is favorable.

Hyperhomocysteinemia in Patients with Newly Diagnosed Primary Hypertension in Can Tho City, Vietnam.

Background: Elevated levels of blood total homocysteine is one of the cardiovascular risk factors in hypertensive patients. Objectives: Determine the prevalence of hyperhomocysteinemia and its associated factors in newly diagnosed primary hypertension patients. Materials and methods: A cross-sectional descriptive study on 105 patients with newly diagnosed primary hypertension at Can Tho University of Medicine and Pharmacy Hospital from May 2017 to May 2018. Total homocysteine levels and related factors were collected at the study time. Results: The mean plasma total homocysteine level was 16.24 ± 4.49 µmol/L. There were 78 patients with elevated plasma total homocysteine levels ≥15 µmol/L, accounting for 74.3% of all patients. Being elderly, gender, hypertension stage, and diabetes were factors associated with hyperhomocysteinemia (p < 0.05). Total homocysteine levels were positively correlated with SBP, DBP, and age with r(SBP) = 0.696, r(DBP) = 0.585, and r(age) = 0.286. Conclusion: Research on the subpopulation of Vietnamese people shows that hyperhomocysteinemia is common in patients with newly diagnosed primary hypertension, and high blood total homocysteine levels are often related to age, sex, hypertension stage, and diabetes.

Effectiveness of Spironolactone in Terms of Galectin-3 Levels in Patients with Heart Failure with a Reduced Ejection Fraction in the Vietnamese Population.

Background: Galectin-3 is a biomarker that has been demonstrated to play a significant role in myocardial fibrosis and remodeling in the pathogenesis of heart failure. Furthermore, spironolactone has the ability to control galectin-3 levels in heart failure patients. Objectives: The aim of our study was to determine the factors associated with the increase in galectin-3 and the alteration of galectin-3 concentration in patients with heart failure with a reduced ejection fraction after 12 weeks of treatment with spironolactone. Materials and methods: A cross-sectional descriptive study was conducted on 122 patients with heart failure with a reduced ejection fraction. Those patients were nonusers of spironolactone and presented for examination or had been hospitalized at the Can Tho Cardiovascular Hospital in Vietnam. The demographic and cardiovascular risk factor details were obtained at baseline, and galectin-3 levels were measured at baseline and also 12 weeks after taking spironolactone 25 mg once daily vs. 50 mg once daily. Results: The median baseline galectin-3 was 54.82 ± 26.06. Galectin-3 levels were positively correlated with age, NT-proBNP, and negatively correlated between EF and galectin-3 levels (p < 0.05). After 12 weeks of treatment with spironolactone, the galectin-3 concentration decreased from 54.82 ± 26.06 to 44.20 ± 24.36 (p < 0.05). According to the subgroup analysis, the average concentration of galectin-3 decreased the most in the group of patients with grade 3 hypertension and NYHA class III heart failure. The 50 mg once-daily dose of spironolactone significantly improved galectin-3 concentrations compared with the 25 mg once-daily group, at 17.11 ± 20.81 (p < 0.05) (reduced 29.05%) and 3.46 ± 6.81 ng/mL (p < 0.05) (reduced 6.87%), respectively. Conclusion: Treatment with spironolactone played an essential role in reducing galectin-3 concentrations, especially spironolactone 50 mg once daily, which showed a significant effect on reducing galectin-3 compared with a 25 mg once-daily dose.
