Introduction and Objectives

Chronic liver diseases are increasingly prevalent in Latin America, where fragmented care and hospital overcrowding limit timely, cost-effective management. Nurse-led outpatient programs may offer a viable alternative in resource-constrained environments.
To evaluate the safety and cost-effectiveness of a nurse-driven Outpatient Intervention Program (OIP) for patients with liver disease and its potential scalability across Latin America.

Materials and Methods

An OIP was implemented in 2019 at a tertiary care transplantation center. The program included outpatient liver biopsies (LB), albumin and blood product infusions, and diagnostic/therapeutic paracentesis. Retrospective data from 2019-2024 were analyzed.

Results

A total of 418 procedures were performed on 258 patients: 162 LB, 104 albumin or blood product infusions, and 152 paracentesis. This demonstrates a 3,240% increase in the number of LB and a 1,680% increase in paracentesis compared to 2018, before the program began.
The overall complication rate was 0.87% (4 complications), with only 2 major events (0.43%): spontaneous bacterial peritonitis after paracentesis and post-biopsy bleeding.
LB costs dropped from $2,894 to $549, generating $379,890 in savings over six years, due to avoiding overnight hospitalization. Paracentesis, albumin infusions and blood transfusions were previously performed in the emergency department, incurring an additional expense of $420. This transition to OIP generated total savings of $107,160 and contributed to reduced congestion in the emergency department.

Conclusions

This nurse-led model yields promising results in outpatient liver care and represents a cost-effective, Potential intervention. Its integration into public health systems across Latin America could contribute to more efficient management of CLD.
介绍和目的慢性肝病在拉丁美洲日益流行,在那里,分散的护理和医院过度拥挤限制了及时、具有成本效益的管理。护士主导的门诊项目可能在资源有限的环境中提供一个可行的替代方案。评估护士驱动的肝病患者门诊干预计划(OIP)的安全性和成本效益及其在拉丁美洲的潜在可扩展性。材料与方法san OIP于2019年在一家三级医疗移植中心实施。该计划包括门诊肝活检(LB),白蛋白和血液制品输注,以及诊断/治疗性穿刺。对2019-2024年的回顾性数据进行分析。结果258例患者共行418例手术,其中LB 162例,白蛋白或血液制品输注104例,穿刺152例。这表明,与该计划开始前的2018年相比,LB数量增加了3240%,穿刺术增加了1680%。总并发症发生率为0.87%(4例并发症),主要事件仅2例(0.43%):穿刺后自发性细菌性腹膜炎和活检后出血。LB费用从2,894美元降至549美元,由于避免了过夜住院治疗,六年内节省了379,890美元。以前在急诊科进行穿刺术、白蛋白注射和输血,额外费用420美元。向伊办的过渡共节省107 160美元,并有助于减少急诊科的拥挤情况。结论:这种护士主导的模式在门诊肝脏护理中取得了良好的效果,代表了一种具有成本效益的潜在干预措施。将其纳入整个拉丁美洲的公共卫生系统可能有助于更有效地管理CLD。

Introduction and Objectives

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent liver disease globally, with 25–30% of patients progressing to fibrosis. It is associated with complications such as cirrhosis, liver failure, and liver cancer. Transient liver elastography (TLE) is a non-invasive, reliable tool to assess hepatic steatosis and fibrosis, with lower risk than biopsy. This study aims to characterize patients with MASLD at Fundación Cardioinfantil by analyzing demographic and clinical factors, and the grade of liver steatosis and fibrosis using TLE

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent liver disease globally, with 25–30% of patients progressing to fibrosis. It is associated with complications such as cirrhosis, liver failure, and liver cancer. Transient liver elastography (TLE) is a non-invasive, reliable tool to assess hepatic steatosis and fibrosis, with lower risk than biopsy. This study aims to characterize patients with MASLD at Fundación Cardioinfantil by analyzing demographic and clinical factors, and the grade of liver steatosis and fibrosis using TLE

Results

In the interim analysis of 899 patients, elastography results met international quality standards (IQR/M 18.3). The average BMI was 27.2 kg/m2, and common comorbidities included hypertension and diabetes. Steatosis was typically moderate (LiSA S2), with a higher LiSA score in those with higher BMI (graphic 1). Fibrosis was absent in 78.3% of cases, while 21.7% showed progression (table 1) of this population 69.9% have overweight or obesity.

Conclusions

MASLD is primarily associated with metabolic diseases. This study found that higher BMI is linked to an increased risk of steatosis, and higher levels of fibrosis were seen in older patients (with no linear relationship). These patients should be prioritized for early screening and treatment, reducing complications and overall morbidity and mortality.

Introduction and Objectives

Given the growing burden of antimicrobial resistance (AMR), we aimed to report the prevalence of key AMR patterns in Latin American patients with cirrhosis and compare them with the European Antimicrobial Resistance Surveillance Network (EARS-Net) data

Materials and Methods

Cross-sectional study of invasive isolates (blood, ascitic or pleural fluid) from adults with cirrhosis enrolled in the Latin American surveillance registry (ClinicalTrials.gov: NCT0634940). AMR patterns were reported for key pathogens: E. coli, K. pneumoniae, S. aureus, Acinetobacter spp., E. faecium, and P. aeruginosa.

Results

Between December 2020 and May 2025, 908 bacterial isolates were collected from Argentina, Uruguay, Brazil, and Peru. Of these, 226 (25%) were obtained from invasive sites and correspond to predefined bacteria of epidemiological interest included in the analysis. Isolates were 39% nosocomial, 38% community-acquired, and 23% healthcare-associated. The main infections were spontaneous bacteremia (38%) and SBP (32%). Quinolone resistance was higher in Latin American vs. Europe for K. pneumoniae (56% vs. 34%) and E. coli (46% vs. 24%). Carbapenem resistance in K. pneumoniae was 46% (vs. 13%), and in E. coli, 5.3% (vs. 0.3%). Methicillin resistance among S. aureus was higher in Latin American (32%) than in Europe (16%). Other pathogens also showed higher resistance (Table).

Conclusions

The elevated resistance rates observed in Latin American patients with cirrhosis demand attention. In a region where regulatory gaps at multiple levels may contribute to antibiotic misuse, these findings call for urgent action to strengthen rational antibiotic use and implement effective stewardship strategies.
鉴于抗菌素耐药性(AMR)的负担日益加重,我们旨在报告拉丁美洲肝硬化患者中主要AMR模式的流行情况,并将其与欧洲抗菌素耐药性监测网络(ear - net)数据进行比较。材料和方法对拉丁美洲监测登记处(ClinicalTrials.gov: NCT0634940)登记的成年肝硬化患者的侵袭性分离物(血液、腹水或胸膜液)进行横断面研究。报告了主要病原体的抗菌素耐药性模式:大肠杆菌、肺炎克雷伯菌、金黄色葡萄球菌、不动杆菌、粪肠杆菌和铜绿假单胞菌。结果2020年12月至2025年5月,在阿根廷、乌拉圭、巴西和秘鲁共分离到908株细菌。其中226个(25%)来自入侵点,与分析中预先确定的流行病学兴趣细菌相对应。分离株39%是医院感染,38%是社区获得,23%是卫生保健相关。主要感染为自发性菌血症(38%)和收缩压(32%)。拉丁美洲的肺炎克雷伯菌(56%对34%)和大肠杆菌(46%对24%)对喹诺酮类药物的耐药性高于欧洲。肺炎克雷伯菌对碳青霉烯的耐药性为46% (vs. 13%),大肠杆菌为5.3% (vs. 0.3%)。金黄色葡萄球菌对甲氧西林的耐药性在拉丁美洲(32%)高于欧洲(16%)。其他病原体也表现出更高的耐药性(表)。结论拉丁美洲肝硬化患者耐药率升高值得关注。在一个多个层面的监管缺口可能导致抗生素滥用的地区,这些发现呼吁采取紧急行动,加强抗生素的合理使用并实施有效的管理战略。

Introduction and Objectives

Primary biliary cholangitis (PBC) is an autoimmune cholestatic disease, typically diagnosed by the presence of anti-mitochondrial antibodies (AMA). Whether AMA-negative PBC represents a distinct clinical phenotype remains controversial. This study aimed to characterize the epidemiological profile of PBC according to AMA status in Latin America.

Materials and Methods

This ongoing, retrospective, international multicenter cohort study, sponsored by ALEH, includes PBC patients from multiple Latin American countries. Patients were stratified by AMA status; those with autoimmune hepatitis-PBC overlap were excluded.

Results

Data from 1,204 patients were analyzed: Brazil (48.3%), Argentina (23.4%), Chile (10.8%), Mexico (7.4%), and others. Most were female (92.3%) with a mean age at diagnosis of 53±13 years; 22.2% had cirrhosis at baseline. Overlap syndrome was excluded. AMA were positive in 76.8%. AMA-positive and AMA-negative patients had similar rates of female sex (92.5% each, p=0.963), baseline cirrhosis (22.4% vs. 23.6%, p=0.706), and symptomatic presentation (77.5% vs. 79.4%, p=0.544). MASLD was more frequent among AMA-negative patients (7.5% vs. 3.8%, p=0.024), which also had higher rates of sp100 (9.1% vs 2.5%, p< 0.001) and gp210 (7.3 vs 3.3%, p< 0.001) positivity. Treatment with UDCA was performed in 95.2% of patients and, from those, 28.3% had second line treatment indicated due to incomplete response to UDCA. AMA-positive patients showed higher response to ursodeoxycholic acid (UDCA) at 12 months, including ALP normalization (29.7% vs. 21.2%, p=0.035) and deep response (17.5% vs. 8.6%, p=0.007). Similar findings were observed after 12 months of fibrate therapy (34.8% vs. 9.4%, p=0.005). No difference was found in transplant-free survival (p=0.213).

Conclusions

AMA-negative PBC patients in Latin America present similar baseline features but have lower response rates to UDCA and fibrates, supporting the hypothesis of a biologically distinct disease subset.
原发性胆道胆管炎(PBC)是一种自身免疫性胆汁淤积性疾病,通常通过抗线粒体抗体(AMA)诊断。ama阴性PBC是否代表一种独特的临床表型仍然存在争议。本研究旨在根据拉丁美洲AMA状况描述PBC的流行病学特征。材料和方法这项正在进行的、回顾性的、国际多中心队列研究,由ALEH赞助,包括来自多个拉丁美洲国家的PBC患者。根据AMA状态对患者进行分层;排除自身免疫性肝炎- pbc重叠者。结果分析1204例患者的数据:巴西(48.3%)、阿根廷(23.4%)、智利(10.8%)、墨西哥(7.4%)等。多数为女性(92.3%),平均诊断年龄53±13岁;22.2%基线时有肝硬化。排除重叠综合征。AMA阳性占76.8%。ama阳性和ama阴性患者的女性比例相似(各92.5%,p=0.963),基线肝硬化(22.4%对23.6%,p=0.706),症状表现(77.5%对79.4%,p=0.544)。MASLD在ama阴性患者中更为常见(7.5%比3.8%,p=0.024), sp100阳性率(9.1%比2.5%,p= 0.001)和gp210阳性率(7.3比3.3%,p= 0.001)也更高。95.2%的患者接受了UDCA治疗,其中28.3%的患者由于UDCA不完全缓解而接受了二线治疗。ama阳性患者在12个月时对熊去氧胆酸(UDCA)的反应更高,包括ALP正常化(29.7% vs. 21.2%, p=0.035)和深度反应(17.5% vs. 8.6%, p=0.007)。贝特治疗12个月后观察到类似的结果(34.8%比9.4%,p=0.005)。无移植生存无差异(p=0.213)。结论拉丁美洲的sama阴性PBC患者具有相似的基线特征,但对UDCA和贝特类药物的反应率较低,支持了生物学上不同疾病亚群的假设。

Introduction and Objectives

Introduction: Quality indicators (QIs) for the management of acute variceal bleeding (AVB) encompass guideline-recommended interventions aimed at reducing mortality. However, the cumulative impact of full adherence to these measures remains unclear.
To evaluate whether complete compliance with five established QIs during AVB episodes is associated with reduced 6-week mortality.

Materials and Methods

This retrospective observational study included 135 AVB episodes from 2017 to 2024. Adherence to five QIs was assessed: antibiotic administration within 24 hours, vasoactive agent used within 24 hours, diagnostic endoscopy within 24 hours, endoscopic treatment, and beta-blocker prescription at discharge. Full adherence was defined as compliance with all five interventions. The primary outcome was 6-week mortality. Descriptive statistics and multivariate logistic regression adjusted for MELD score (<15 vs. ≥15) and Child-Pugh class (A/B vs. C) were performed. An interaction term was included to evaluate whether the effect of QI compliance differed by Child-Pugh class.

Results

Overall 6-week mortality was 13.8%. Full adherence was achieved in 54.8% of episodes. Mortality rates by adherence level were 4.1% for full adherence, 16.3% for four QIs, and 42.9% for three or fewer QIs (p < 0.001). In multivariate analysis, full adherence was independently associated with lower mortality (OR 0.20; 95% CI 0.05–0.82; p = 0.025). Child-Pugh class C was also significantly associated with increased mortality (OR 9.68; p = 0.001). An interaction analysis showed that the protective effect of QI adherence did not differ significantly between Child-Pugh A/B and Child-Pugh C patients (interaction term p = 0.87), suggesting a consistent benefit across severity strata.

Conclusions

Complete compliance with evidence-based quality indicators significantly reduces 6-week mortality in patients with AVB, independent of baseline liver disease severity. Rigorous implementation of these measures should be prioritized as a standard of care in cirrhotic patients presenting with AVB.
简介和目的简介:急性静脉曲张出血(AVB)管理的质量指标(QIs)包括指南推荐的旨在降低死亡率的干预措施。然而,全面遵守这些措施的累积影响仍不清楚。评估AVB发作期间完全遵守5个已建立的QIs是否与降低6周死亡率相关。材料与方法本回顾性观察研究纳入2017 - 2024年135例AVB发作。评估5个QIs的依从性:24小时内给药抗生素,24小时内使用血管活性药物,24小时内诊断内窥镜检查,内窥镜治疗,出院时处方β受体阻滞剂。完全依从性被定义为遵守所有五种干预措施。主要终点为6周死亡率。对MELD评分(<15 vs.≥15)和Child-Pugh分级(A/B vs. C)进行描述性统计和多因素logistic回归校正。采用交互作用项来评价不同Child-Pugh班级的QI依从性是否存在差异。结果6周总死亡率为13.8%。54.8%的发作达到完全依从性。完全依从性组死亡率为4.1%,4次QIs组死亡率为16.3%,3次或更少QIs组死亡率为42.9% (p < 0.001)。在多变量分析中,完全依从性与较低的死亡率独立相关(OR 0.20; 95% CI 0.05-0.82; p = 0.025)。Child-Pugh C级也与死亡率增加显著相关(OR 9.68; p = 0.001)。相互作用分析显示,QI依从性的保护作用在Child-Pugh A/B和Child-Pugh C患者之间没有显著差异(相互作用项p = 0.87),表明在不同严重程度的患者中都有一致的益处。结论:完全符合循证质量指标可显著降低AVB患者6周死亡率,与基线肝病严重程度无关。严格实施这些措施应优先作为肝硬化AVB患者的标准护理。

Introduction and Objectives

The World Health Organization (WHO) aims to eliminate hepatitis C virus (HCV) by 2030; however, the United States (US) is unlikely to meet this target. Screening, linkage, and treatment initiation remain suboptimal.
To evaluate Point-of-care (POC) HCV RNA test (Xpert® HCV) in a test and treat model of care among People Who Use Drugs (PWUD).

Materials and Methods

La Bodega, a co-localized hepatology and addiction medicine program in Buffalo, New York (NY), specializes in HCV management among active PWUD. POC HCV RNA testing is utilized on-site. Patients with a positive HCV RNA initiate HCV therapy at the time of the initial visit. POC HCV RNA testing is also used in conjunction with lab-based RNA testing on serum to evaluate SVR4 when indicated.

Results

65 people were screened with POC HCV RNA of whom 40 had a previous HCV antibody. 11 individuals were found to be HCV RNA positive. Eleven individuals were assessed for SVR, all of whom had both undetectable serum HCV RNA and negative POC HCV RNA results. Among RNA-positive individuals, one was linked to their primary care clinic based on the patient’s preference and 10 individuals initiated therapy, receiving the full 8 or 12 weeks of therapy, depending on the chosen regimen. Two individuals remain on treatment; 6 are pending SVR assessment, and 2 achieved SVR, one of whom was pregnant and treated with sofosbuvir/velpatasvir.

Conclusions

POC HCV RNA testing is advantageous in shortening the HCV care cascade, enabling a true test-and-treat model of care for HCV.
世界卫生组织(WHO)的目标是到2030年消除丙型肝炎病毒(HCV);然而,美国不太可能实现这一目标。筛查、联系性和开始治疗仍不理想。评估即时护理(POC) HCV RNA检测(Xpert®HCV)在药物使用人群(PWUD)的检测和治疗模式中的应用。材料和方法sla Bodega是位于纽约州布法罗市的肝病学和成瘾医学联合项目,专门研究活动性PWUD患者的HCV管理。现场使用POC HCV RNA检测。HCV RNA阳性的患者在初次就诊时开始HCV治疗。如有需要,POC HCV RNA检测也可与基于实验室的血清RNA检测结合使用,以评估SVR4。结果65人筛查出POC HCV RNA,其中40人既往有HCV抗体。11例HCV RNA阳性。对11名患者进行SVR评估,所有患者血清HCV RNA均检测不到,POC HCV RNA结果均为阴性。在rna阳性的个体中,根据患者的偏好,1人与他们的初级保健诊所联系,10人开始治疗,接受完整的8或12周的治疗,取决于所选择的方案。两人仍在接受治疗;6人正在等待SVR评估,2人达到SVR,其中1人怀孕并接受sofosbuvir/velpatasvir治疗。结论spoc HCV RNA检测有利于缩短HCV护理级联,实现真正的HCV检测和治疗模式。

Introduction and Objectives

Covert hepatic encephalopathy (CHE) is a complication that affects the quality of life and prognosis of cirrhotic patients. It is identified through appropriate neuropsychological tests. Objectives: To determine the prevalence of CHE in patients with compensated liver cirrhosis using the Psychometric Hepatic Encephalopathy Score (PHES) and its association with selected clinical factors.

Materials and Methods

A descriptive, cross-sectional study was conducted at the Institute of Gastroenterology in Havana, Cuba, between March 2023 and December 2024. Sixty-five patients with defined selection criteria were included. The prevalence of CHE was calculated according to the total PHES, using normality tables for the Cuban population. PHES scores and laboratory parameters were compared, and the association with sex, age, education, and etiology was explored between the groups with and without EHE.

Results

The prevalence of EHE was 32.3% (n=21). Differences were found between groups with and without EHE in the total PHES (p<0.001) and in each of its components. No association was demonstrated between age, sex, educational level, and etiology of cirrhosis with EHE, nor was there statistical significance between ALAT (p=0.68), ASAT (p=0.90), albumin (p=0.65), and platelet count (p=0.63). Age >60 years, male sex, viral etiology, low educational level, and liver function did not influence the diagnosis of EHE.

Conclusions

The PHES is an objective tool that allowed the identification of EHE in the context studied, which is relevant for the early management of compensated cirrhosis.
隐蔽性肝性脑病(CHE)是一种影响肝硬化患者生活质量和预后的并发症。它是通过适当的神经心理学测试来确定的。目的:利用肝性脑病心理测量评分(PHES)确定代偿性肝硬化患者中CHE的患病率及其与选定临床因素的关系。材料与方法一项描述性横断面研究于2023年3月至2024年12月在古巴哈瓦那胃肠病学研究所进行。纳入了65例具有明确选择标准的患者。利用古巴人口的正态表,根据公共卫生指数的总数计算了古巴疾病的患病率。比较EHE组和非EHE组的PHES评分和实验室参数,并探讨其与性别、年龄、教育程度和病因的关系。结果EHE患病率为32.3% (n=21)。在有EHE和没有EHE的组之间,总PHES (p<0.001)及其每个组成部分存在差异。年龄、性别、受教育程度、肝硬化病因与EHE无相关性,ALAT (p=0.68)、ASAT (p=0.90)、白蛋白(p=0.65)、血小板计数(p=0.63)之间无统计学意义。年龄60岁、男性、病毒病因、低文化程度、肝功能对EHE的诊断无影响。结论PHES是一种客观的工具,可以在研究的背景下识别EHE,这与代偿性肝硬化的早期治疗有关。

Introduction and Objectives

Health literacy (HL) is a key social determinant of health, especially in chronic conditions like cirrhosis, where disease management depends heavily on patient comprehension and engagement. HL refers to the ability to access, understand, and use health information to make informed decisions. Frailty, a state of decreased physiological reserve and increased vulnerability, is a strong predictor of adverse outcomes in cirrhosis. Although the Liver Frailty Index (LFI) is commonly used to assess physical frailty, the role of HL in this context remains poorly explored. This study aimed to determine the association between HL and frailty in patients with cirrhosis.

Patients and Methods

We conducted a cross-sectional study among adults with confirmed cirrhosis attending outpatient hepatology clinics in Cartagena, Colombia, between September and December 2024. HL was measured using the Short Assessment of Health Literacy for Spanish Adults (SAHL-S), and frailty was assessed with the LFI, which includes grip strength, chair stands, and balance tests. Trained clinicians performed all tests using calibrated equipment. Demographic and clinical variables were obtained from records and structured interviews. Patients with encephalopathy or severe mobility limitations were excluded. Frailty was defined as LFI ≥ 4.5.

Results

Among 89 participants (57.3% women, mean age 64.8), 85.4% were Child-Pugh A. History of decompensation and variceal bleeding were present in 24.7% and 13.5%, respectively. LFI categorized 15.7% as robust, 65.2% as prefrail, and 19.1% as frail. In multivariable analysis, low HL (OR 2.8; 95% CI 1.3–6.0) and variceal bleeding (OR 3.2; 95% CI 1.4–7.1) independently predicted frailty.

Conclusions

Low HL independently predicts frailty and should be addressed to improve outcomes in cirrhosis care.
健康素养(HL)是健康的关键社会决定因素,特别是在肝硬化等慢性疾病中,疾病管理在很大程度上取决于患者的理解和参与。HL是指获取、理解和使用卫生信息以做出明智决策的能力。虚弱,一种生理储备减少和脆弱性增加的状态,是肝硬化不良结局的一个强有力的预测因子。尽管肝脆弱指数(LFI)通常用于评估身体虚弱,但HL在这方面的作用仍未得到充分探讨。本研究旨在确定HL与肝硬化患者虚弱之间的关系。患者和方法我们对2024年9月至12月在哥伦比亚卡塔赫纳肝病门诊就诊的确诊肝硬化成人进行了一项横断面研究。使用西班牙成人健康素养短期评估(SAHL-S)测量HL,使用LFI评估虚弱程度,其中包括握力、椅架和平衡测试。训练有素的临床医生使用校准的设备进行所有测试。从记录和结构化访谈中获得人口统计学和临床变量。排除有脑病或严重活动受限的患者。虚弱定义为LFI≥4.5。结果89名参与者中(57.3%为女性,平均年龄64.8岁),85.4%为Child-Pugh a。有失代偿史和静脉曲张出血分别占24.7%和13.5%。LFI将15.7%归类为健壮,65.2%为虚弱,19.1%为虚弱。在多变量分析中,低HL (OR 2.8; 95% CI 1.3-6.0)和静脉曲张出血(OR 3.2; 95% CI 1.4-7.1)独立预测虚弱。结论:slow HL独立预测衰弱,应加以解决,以改善肝硬化护理的结果。

Introduction and Objectives

Sorafenib (SB), while established as a first-line multikinase inhibitor for advanced hepatocellular carcinoma (HCC), demonstrates constrained clinical utility due to significant adverse effects and the emergence of drug resistance. To potentially enhance its therapeutic profile, we explored combination therapy with natural compounds. Previous investigations from our group identified safranal (SF), a major bioactive monoterpene constituent of saffron, as exhibiting notable anti-HCC properties.
This study aimed to investigate potential synergistic interactions between SB and SF that might improve HCC treatment outcomes.

Materials and Methods

We employed a chemically-induced cirrhotic HCC rat model to evaluate both SF monotherapy and SB-SF combination therapy. Comprehensive molecular characterization included RNA sequencing with subsequent differential gene expression analysis, pathway enrichment studies, and protein interaction network mapping. Mechanistic findings were confirmed through immunohistochemical and immunoblotting techniques.

Results

The SB-SF combination demonstrated enhanced anticancer efficacy compared to SB alone. Transcriptomic profiling identified 45 differentially expressed genes associated with HCC suppression, particularly those involved in proliferation control, oxidative stress response, and apoptotic regulation. The combination therapy significantly downregulated key oncogenic markers including NF-κB-p65, COX-2, and β-catenin, suggesting its potential as a cost-effective therapeutic approach that warrants further clinical investigation.

Conclusions

The study reveals a multifaceted mechanism by which SF augments SB's anticancer activity in HCC. The combined treatment modulates critical oncogenic pathways including NF-κB and Wnt/β-catenin signaling while rebalancing apoptotic regulators through decreased Bcl-2 and increased Bax/caspase expression. Additionally, it suppresses proliferative markers such as Ki-67 and PCNA while attenuating inflammatory mediators including TNF-α and MMP-9. These coordinated effects demonstrate potent anti-tumorigenic, anti-angiogenic, and pro-apoptotic activity, highlighting the therapeutic promise of this combination approach for HCC treatment.
orafenib (SB)作为治疗晚期肝细胞癌(HCC)的一线多激酶抑制剂,由于明显的不良反应和耐药的出现,其临床应用受到限制。为了潜在地提高其治疗效果,我们探索了与天然化合物的联合治疗。本小组先前的研究发现,藏红花中一种主要的生物活性单萜成分——藏红花醛(SF),具有显著的抗hcc特性。本研究旨在探讨SB和SF之间可能改善HCC治疗结果的潜在协同相互作用。材料与方法采用化学诱导的肝硬化肝细胞癌大鼠模型,对SF单药治疗和SF -SF联合治疗进行评价。全面的分子表征包括RNA测序和随后的差异基因表达分析、途径富集研究和蛋白质相互作用网络制图。机制发现通过免疫组织化学和免疫印迹技术证实。结果与单用SB相比,SB- sf联合用药的抗癌效果明显增强。转录组学分析鉴定了45个与HCC抑制相关的差异表达基因,特别是那些涉及增殖控制、氧化应激反应和凋亡调节的基因。联合治疗显著下调关键的致癌标志物,包括NF-κB-p65、COX-2和β-catenin,表明其作为一种具有成本效益的治疗方法的潜力,值得进一步的临床研究。结论本研究揭示了SF增强SB在HCC中抗肿瘤活性的多方面机制。联合治疗可调节关键的致癌途径,包括NF-κB和Wnt/β-catenin信号通路,同时通过降低Bcl-2和增加Bax/caspase表达来重新平衡凋亡调节因子。此外,它抑制增殖标志物如Ki-67和PCNA,同时减弱炎症介质包括TNF-α和MMP-9。这些协同作用显示出强大的抗肿瘤、抗血管生成和促凋亡活性,突出了这种联合治疗方法在HCC治疗中的治疗前景。

Introduction and Objectives

Co-infection with Human Immunodeficiency Virus (HIV) and hepatitis C virus (HCV) represents a significant public health challenge in Brazil, as it is associated with worsening clinical outcomes, such as accelerated progression of liver disease and increased morbidity and mortality.
To describe the rate of incomplete reporting related to HCV and HIV co-infection among individuals notified between 2013 and 2023 in the North region of Brazil.

Materials and Methods

This is a descriptive, cross-sectional study conducted using data from the Notifiable Diseases Information System (Sinan) database for the period from 2013 to 2023. The variables used were viral hepatitis classification and co-infection with HIV. Subsequently, a descriptive analysis was performed to identify omissions in the HIV co-infection variable in viral hepatitis notifications.

Results

A high number (18.6%) of data omissions was observed regarding HIV and viral hepatitis co-infection. Among the types, the highest omission rate was observed in hepatitis A notifications (21.7%), followed by hepatitis C (20.3%) and hepatitis B (17%). Among the states, Roraima showed the highest percentage of omission of information on HIV diagnosis (23.2%).

Conclusions

The data reveal a significant percentage of omissions regarding the investigation of HIV co-infection in viral hepatitis notifications, especially for hepatitis A (21.7%), C (20.3%), and B (17%). This weakness in the completeness of information compromises epidemiological surveillance and health action planning.
在巴西,人类免疫缺陷病毒(HIV)和丙型肝炎病毒(HCV)的合并感染是一项重大的公共卫生挑战,因为它与临床结果恶化有关,例如肝病进展加快、发病率和死亡率增加。描述巴西北部地区2013年至2023年通报的个人中与丙型肝炎病毒和艾滋病毒合并感染相关的不完整报告率。材料和方法这是一项描述性横断面研究,使用2013年至2023年期间来自法定疾病信息系统(思南)数据库的数据。使用的变量是病毒性肝炎分类和合并感染HIV。随后,进行了描述性分析,以确定病毒性肝炎报告中HIV合并感染变量的遗漏。结果HIV与病毒性肝炎合并感染的数据漏报率高达18.6%。其中,漏报率最高的是甲型肝炎(21.7%),其次是丙型肝炎(20.3%)和乙型肝炎(17%)。在各州中,罗赖马州遗漏艾滋病毒诊断信息的比例最高(23.2%)。结论数据显示,病毒性肝炎报告中HIV合并感染调查的遗漏率很高,特别是甲型肝炎(21.7%)、丙型肝炎(20.3%)和乙型肝炎(17%)。这种信息不完整的弱点影响了流行病学监测和卫生行动规划。
