RESUMEN

Introduction: An estimated 43% of COVID-19 patients showed sequelae, including fatigue, neurocognitive impairment, respiratory symptoms, and smell or taste disorders. These sequelae significantly affect an individual's health, work capacity, healthcare systems, and socioeconomic aspects. Traditional Chinese herbal medicine (TCHM) management showed clinical benefits in treating patients with COVID-19 sequelae. This study aimed to analyze the effects of personalized TCHM management in patients with COVID-19 sequelae. Methods: After the COVID-19 outbreak in Taiwan, we recorded Chronic Obstructive Pulmonary Disease Assessment Tool (CAT), Chalder Fatigue Questionnaire (CFQ-11), and Brief Symptom Rating Scale (BSRS-5) to assess post-COVID respiratory, fatigue, and emotional distress symptoms, respectively. In this study, we retrospectively reviewed the medical records between July 2022 and March 2023. We analyzed the effects of TCHM administration after 14- and 28-days of treatment. Results: 47 patients were included in this study. The results demonstrated that personalized TCHM treatment significantly improved the CAT, CFQ-11, and BSRS-5 scores after 14 and 28 days. TCHM alleviated physical and psychological fatigue. In logistic regression analysis, there was no statistically significant differences in the severity of the baseline symptoms and TCHM administration effects concerning the duration since the initial confirmation of COVID-19, sex, age, or dietary preference (non-vegetarian or vegetarian). Conclusions: Our study suggested that personalized TCHM treatment notably reduced fatigue, respiratory and emotional distress symptoms after 14- and 28-days of treatment in patients with COVID-19 sequelae. We propose that TCHM should be considered as an effective intervention for patients with COVID-19 sequelae.

RESUMEN

Among previously uninfected healthcare workers in Taiwan, mRNA COVID-19 booster vaccine was associated with lower odds of COVID-19 after primary recombinant vaccine. Symptom-triggered testing revealed that tetravalent influenza vaccine was associated with higher odds of SARS-CoV-2 infection. COVID-19 vaccination continues to be most effective against SARS-CoV-2.

RESUMEN

The coronavirus disease 2019 (COVID-19) pandemic is the largest health crisis ever faced worldwide. It has resulted in great health and economic costs because no effective treatment is currently available. Since infected persons vary in presentation from healthy asymptomatic mild symptoms to those who need intensive care support and eventually succumb to the disease, this illness is considered to depend primarily on individual immunity. Demographic distribution and disease severity in several regions of the world vary; therefore, it is believed that natural inherent immunity provided through dietary sources and traditional medicines could play an important role in infection prevention and disease progression. People can boost their immunity to prevent them from infection after COVID-19 exposure and can reduce their inflammatory reactions to protect their organ deterioration in case suffering from the disease. Some drugs with in-situ immunomodulatory and anti-inflammatory activity are also identified as adjunctive therapy in the COVID-19 era. This review discusses the importance of COVID-19 interactions with immune cells and inflammatory cells; and further emphasizes the possible pathways related with traditional herbs, medications and nutritional products. We believe that such pathophysiological pathway approach treatment is rational and important for future development of new therapeutic agents for prevention or cure of COVID-19 infection.

RESUMEN

BACKGROUND/PURPOSE: Radiofrequency ablation (RFA) is increasingly being used instead of surgical resection for the treatment of hepatocellular carcinoma (HCC) tumor measuring ≦2 cm. However, the long-term outcomes of RFA, especially in comparison to surgical resection, are still debated. We compared the outcomes of surgical resection and RFA in patients with a solitary HCC tumor measuring ≦2 cm from a 10-year cohort study. METHODS: From Jan 2006 to Dec 2016, 156 patients with a resectable HCC measuring ≦2 cm who underwent surgical resection (n = 83) or RFA (n = 73) at the Buddhist Tzu Chi Medical Foundation were enrolled. Patient characteristics, overall survival (OS), and recurrence-free survival (RFS) were retrospectively examined, and comparisons were made between the two groups and through subgroup analyses. RESULTS: The 1-year, 3-year, 5-year, and 7-year OS outcomes were comparable between the surgical resection group and the RFA group (P = 0.193), but the surgical resection group had significantly higher 1-year, 3-year, 5-year, 7-year, and 10-year RFS than the RFA group (P = 0.018). Multivariate analysis revealed that patients with lower age, Child-Turcotte-Pugh score, or albumin-bilirubin score before treatment had better OS, and patients with an HCV infection or receiving RFA treatment had higher HCC recurrence rates. CONCLUSION: The liver reserve determined the long-term OS of patients with an HCC tumor ≦ 2 cm, and surgical resection offered better RFS than RFA (ClinicalTrials.gov number, NCT04525833.).

RESUMEN

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is still an ongoing global health crisis. Immediately after the inhalation of SARS-CoV-2 viral particles, alveolar type II epithelial cells harbor and initiate local innate immunity. These particles can infect circulating macrophages, which then present the coronavirus antigens to T cells. Subsequently, the activation and differentiation of various types of T cells, as well as uncontrollable cytokine release (also known as cytokine storms), result in tissue destruction and amplification of the immune response. Vitamin D enhances the innate immunity required for combating COVID-19 by activating toll-like receptor 2. It also enhances antimicrobial peptide synthesis, such as through the promotion of the expression and secretion of cathelicidin and ß-defensin; promotes autophagy through autophagosome formation; and increases the synthesis of lysosomal degradation enzymes within macrophages. Regarding adaptive immunity, vitamin D enhances CD4+ T cells, suppresses T helper 17 cells, and promotes the production of virus-specific antibodies by activating T cell-dependent B cells. Moreover, vitamin D attenuates the release of pro-inflammatory cytokines by CD4+ T cells through nuclear factor κB signaling, thereby inhibiting the development of a cytokine storm. SARS-CoV-2 enters cells after its spike proteins are bound to angiotensin-converting enzyme 2 (ACE2) receptors. Vitamin D increases the bioavailability and expression of ACE2, which may be responsible for trapping and inactivating the virus. Activation of the renin-angiotensin-aldosterone system (RAS) is responsible for tissue destruction, inflammation, and organ failure related to SARS-CoV-2. Vitamin D inhibits renin expression and serves as a negative RAS regulator. In conclusion, vitamin D defends the body against SARS-CoV-2 through a novel complex mechanism that operates through interactions between the activation of both innate and adaptive immunity, ACE2 expression, and inhibition of the RAS system. Multiple observation studies have shown that serum concentrations of 25 hydroxyvitamin D are inversely correlated with the incidence or severity of COVID-19. The evidence gathered thus far, generally meets Hill's causality criteria in a biological system, although experimental verification is not sufficient. We speculated that adequate vitamin D supplementation may be essential for mitigating the progression and severity of COVID-19. Future studies are warranted to determine the dosage and effectiveness of vitamin D supplementation among different populations of individuals with COVID-19.

RESUMEN

Severe acute respiratory syndrome coronavirus 2 is a new, highly pathogenic virus that has recently elicited a global pandemic called the 2019 coronavirus disease (COVID-19). COVID-19 is characterized by significant immune dysfunction, which is caused by strong but unregulated innate immunity with depressed adaptive immunity. Reduced and delayed responses to interferons (IFN-I/IFN-III) can increase the synthesis of proinflammatory cytokines and extensive immune cell infiltration into the airways, leading to pulmonary disease. The development of effective treatments for severe COVID-19 patients relies on our knowledge of the pathophysiological components of this imbalanced innate immune response. Strategies to address innate response factors will be essential. Significant efforts are currently underway to develop vaccines against SARS-CoV-2. COVID-19 vaccines, such as inactivated DNA, mRNA, and protein subunit vaccines, have already been applied in clinical use. Various vaccines display different levels of effectiveness, and it is important to continue to optimize and update their composition in order to increase their effectiveness. However, due to the continuous emergence of variant viruses, improving the immunity of the general public may also increase the effectiveness of the vaccines. Many observational studies have demonstrated that serum levels of vitamin D are inversely correlated with the incidence or severity of COVID-19. Extensive evidence has shown that vitamin D supplementation could be vital in mitigating the progression of COVID-19 to reduce its severity. Vitamin D defends against SARS-CoV-2 through a complex mechanism through interactions between the modulation of innate and adaptive immune reactions, ACE2 expression, and inhibition of the renin-angiotensin system (RAS). However, it remains unclear whether Vit-D also plays an important role in the effectiveness of different COVID-19 vaccines. Based on analysis of the molecular mechanism involved, we speculated that vit-D, via various immune signaling pathways, plays a complementary role in the development of vaccine efficacy.

RESUMEN

BACKGROUND/PURPOSE: To investigate contemporary cardiovascular (CV) outcomes in Taiwanese patients with symptomatic low extremity peripheral artery disease treated with endovascular therapy. METHODS: An observational cohort study with up to 155 months of follow-up was conducted using a single-center registry database between July 2005 and June 2017. Long-term outcomes and predictors of future CV events were analyzed in 936 patients with 1246 affected legs. RESULTS: This study cohort comprised 21% claudicants and 79% critical limb ischemia (CLI) patients. Compared with claudicants, CLI patients had higher rates of medical comorbidities, tissue inflammation, and lesion complexities. During the study period, 349 patients died (130 CV deaths and 219 non-CV deaths), 306 had non-fatal CV events. The rates of 5-year freedom from all-cause mortality, major CV events (MACEs), and non-fatal CV events were 54.9%, 67.1%, and 56.6% respectively. For CLI patients, independent factors for all-cause mortality were age (odds ratio [OR] 1.03), atrial fibrillation (OR 1.79), albumin (OR 0.62), hematocrit (OR 0.96), body mass index (OR 0.94), C-reactive protein (OR 1.18), dialysis (OR 2.16), and non-ambulance (OR 2.05). Congestive heart failure, dialysis, and non-ambulance independently predicted the MACEs (OR 2.04, 1.93, and 1.67, respectively). For claudicants, coronary artery disease (CAD) was the essential factor for all-cause mortality (OR 2.24), MACE (OR 2.76) and non-fatal CV events (OR 1.82). CONCLUSION: Long-term survival and MACE-free rates were significantly worse in CLI patients than in claudicants. Malnutrition and inflammation were associated with long-term survival. CAD, low hematocrit, dialysis, CHF, and ambulatory status predicted future CV events.

RESUMEN

BACKGROUND: Patients with different hepatitis C virus (HCV) genotype infections are associated with varying metabolic disorders. Although alteration of lipid metabolism has been confirmed as a virus-induced metabolic derangement in chronic hepatitis C patients, the impact of various HCV genotypes on hepatic cholesterol metabolism remains elusive. In this study, we thus investigated the HCV genotype-specific lipogenic and cholesterol metabolism profiles in an in vitro cell culture system. METHODS: We first conducted HCV cell culture system (HCVcc) assays by infecting Huh7.5.1 cells with multiple infection-competent HCV strains, including the genotype 2a JFH1 and JFH1-based intergenotypic recombinants 1b and 3a. We then examined the expression levels of various lipid and cholesterol-related genes. RESULTS: The data showed that infection with individual HCV genotypes exerted unique gene expression regulatory effects on lipoproteins and cholesterol metabolism genes. Of note, all HCV strains suppressed cholesterol biosynthesis in hepatocytes through downregulating the expression of HMG-CoA reductase (HMGCR) and farnesyl-diphosphate farnesyltransferase 1 (FDFT1) - two essential enzymes for cholesterol biosynthesis. These HCV-mediated inhibitory effects could be reversed by treatment with sofosbuvir, a pangenotypic NS5B inhibitor. In addition, overexpression of HCV genotype 1b, 2a or 3a core protein significantly suppressed HMGCR mRNA transcription and translation, thus diminished cellular cholesterol biosynthesis. Nonetheless, the core protein had no effect on FDFT1 expression. CONCLUSION: Although HCV infection regulates host lipid metabolism in a genotype-specific manner, its inhibition on hepatocellular cholesterogenic gene expression and total cholesterol biosynthesis is a common effect among HCV genotype 1b, 2a and 3a.

RESUMEN

Background and objectives: The association between hypnotic drugs and risk of cancer remains controversial. Therefore, we performed a meta-analysis to investigate this association. Materials and Methods: Pubmed and Embase were searched systematically to identify publications up to April 2020. The Newcastle-Ottawa scale for observational studies was used to assess the quality of studies. All included studies were evaluated by two reviewers independently; any discrepancies were resolved through discussion. Results: Twenty-eight studies including 22 case-control studies and 6 cohort studies with 340,614 hypnotics users and 1,828,057 non-users were included in the final analyses. Hypnotics (benzodiazepines and Z-drugs) use was significantly associated with an increased risk of cancer (odds ratio [OR] or relative risk [RR] 1.17; 95% confidence interval 1.09-1.26) in a random-effects meta-analysis of all studies. Subgroup meta-analysis by anxiolytics/sedatives effect (anxiolytics benzodiazepines vs. sedatives group (include sedatives benzodiazepines and Z-drugs)) revealed that a significant association in sedatives group (pooled OR/RR 1.26, 95% CI, 1.10-1.45), whereas no significant relationship was observed in anxiolytics benzodiazepines (pooled OR/RR 1.09, 95% CI, 0.95-1.26). Moreover, a significant dose-response relationship was observed between the use of hypnotics and the risk of cancer. Conclusions: This meta-analysis revealed association between use of hypnotics drugs and risk of cancer. However, the use of lower dose hypnotics and shorter duration exposed to hypnotics seemed to be not associated with an increased risk of cancer. Moreover, the use of anxiolytics effect benzodiazepines seemed to be lower risk than sedatives benzodiazepines. A high heterogeneity was observed among identified studies, and results were inconsistent in some subgroups. Randomized control trials are needed to confirm the findings in the future.

RESUMEN

Background: Gestational diabetes mellitus (GDM) is a condition, in which women develop high blood sugar levels during pregnancy without having diabetes. Evidence on the effects of probiotics on the blood glucose levels of women with GDM is inconsistent. Objective: The present study aimed to investigate the effects of probiotics on the blood glucose levels of pregnant women. Methods: Online databases, such as PubMed, Cochrane, and Excerpta Medica Database (EMBASE) were searched for randomized controlled trials (RCTs) published before July 2018. Trials had to meet the inclusion criteria of our study. Methodological quality and risk bias were independently assessed by two reviewers. Data were pooled using a random effects model and were expressed as the mean difference (MD) and 95% confidence interval (CI). Heterogeneity was evaluated and quantified as I². Results: In total, 12 RCTs were included in this study. Studies have shown that the use of probiotics significantly reduced the fasting blood glucose (FBG) level (MD: -0.10 mmol/L; 95% CI: -0.19, -0.02), insulin concentration (MD: -2.24 µIU/mL; 95% CI: -3.69, -0.79), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) score (MD: -0.47; 95% CI: -0.74, -0.21), and Homeostasis model of assessment-estimated ß cell function (HOMA-B) score (MD: -20.23; 95% CI: -31.98, -8.49) of pregnant women. In a subgroup analysis, whether the blood glucose-lowering effect of probiotics influenced the diagnosis of pregnant women with GDM was assessed. The results showed that probiotics had significantly reduced the fasting blood glucose (FBG) level (MD: -0.10 mmol/L; 95% CI: -0.17, -0.04) and HOMA-IR score (MD: -0.37; 95% CI: -0.72, -0.02) of pregnant women who were not diagnosed with GDM. Conclusion: Probiotics reduce the blood glucose level of pregnant women, especially without GDM diagnosis. However, further research using RCTs must be conducted to validate the results of the present study.

RESUMEN

UNLABELLED: Patients dually infected with hepatitis C virus (HCV)/hepatitis B virus (HBV) have a higher risk of developing advanced liver disease or hepatocellular carcinoma compared with monoinfected patients. Yet, there is a similar rate of sustained virologic response (SVR) after peginterferon alfa-2a and ribavirin combination therapy in these patients compared with HCV-monoinfected patients and a high hepatitis B surface antigen (HBsAg) seroclearance rate. The durability of hepatitis C and B clearance in coinfected patients was investigated in a 5-year follow-up study. Patients with active HCV genotype 1, both HBV-coinfected (n = 97) and HBV-monoinfected (n = 110), underwent 48-week combination therapy with peginterferon alfa-2a plus ribavirin. In patients with active HCV genotype 2 or 3, both HBV-coinfected (n = 64) and monoinfected (n = 50) patients underwent 24-week combination therapy. A total of 295 (91.9%) patients completed treatment and 24 weeks posttreatment follow-up; 264 (89.5%) patients agreed to receive additional follow-up for up to 5 years after the end of treatment. After a median follow-up of 4.6 ± 1.0 years, six of the 232 patients achieving SVR developed HCV RNA reappearance, including five HCV genotype 1/HBV-coinfected patients and one HCV genotype 2/3-monoinfected patient. Subgenomic analysis of the HCV core gene indicated that five patients developed delayed recurrence of HCV infection. Overall, the cumulative recurrence rate of HCV infection was 2.3% (0.4%/year; 95% confidence interval [CI], 0.9%-5.5%). The cumulative HBsAg seroclearance rate was 30.0% (95% CI, 21.5%-42.0%); with 33.1% (95% CI, 21.8%-50.1%) in the 48-week combination therapy group and 24.3% (95% CI, 13.7%-42.9%) in the 24-week therapy group. CONCLUSION: Peginterferon alfa-2a and ribavirin therapy provides good HCV SVR durability and a high accumulative HBsAg seroclearance rate in patients who are coinfected with HCV and HBV.

RESUMEN

BACKGROUND: Immunothrombosis, a process of inflammation and coagulation, is involved in sepsis-induced acute respiratory distress syndrome formation (ARDS). However, the clinical correlation between immunothrombosis biomarkers (including tissue factor [TF] and von Willebrand factor [vWF]) and coronavirus disease 2019 (COVID-19)-related ARDS is unknown. This study investigated ARDS development following moderate-to-critical COVID-19 and examined immunothrombosis biomarkers as ARDS predictors. METHODS: This retrospective cohort study included patients with moderate-to-critical COVID-19 (n = 165) admitted to a northern teaching hospital during the 2021 pandemic in Taiwan, who had no COVID-19 vaccinations. Immunothrombosis biomarkers were compared between COVID-19 patients with and without ARDS (no-ARDS) and a control group consisting of 100 healthy individuals. RESULTS: The study included 58 ARDS and 107 no-ARDS patients. In multivariable analysis, TF (aOR=1.031, 95% CI: 1.009-1.053, p = 0.006); and vWF (aOR=1.053, 95% CI: 1.002-1.105, p = 0.041) were significantly associated with ARDS episodes, after adjusting for other confounding factors. vWF and TF predicted ARDS with the area under the curve of 0.870 (95% CI: 0.796-0.945). Further mechanical ventilation analysis found TF to be correlated significantly with pCO2 and ventilatory ratio. CONCLUSIONS: TF and vWF levels potentially predicted ARDS development within 7 days of admission for COVID-19 after adjusting for traditional risk factors. TF correlated with ventilation impairment in COVID-19 ARDS but further prospective studies are needed.

RESUMEN

BACKGROUND: The aims of this study were to compare results from a Taiwanese sub-study of the GLOBE 2303 telbivudine study and evaluate the HBV DNA kinetics. METHODS: Forty-one Taiwanese patients were treated for an additional 2 years with telbivudine. Efficacy endpoints were the same as the GLOBE study. The correlations of reductions in HBV DNA levels at Week 24 were evaluated. RESULTS: All 7 HBeAg-positive patients with undetectable HBV DNA levels at Week 24 sustained this response at Year 4 with rates of ALT normalization 71%, HBeAg seroconversion 57%, and cumulative resistance 0%. Out of 16 HBeAg-negative patients with undetectable HBV DNA levels at Week 24, 11 (78%) sustained this response at Year 4 with rates of ALT normalization 83% and cumulative resistance 8.7%. There were significant correlations between reductions of DNA of ≥5 log10 copies/mL at Week 24 with maintained PCR negativity at Years 2-4 and a lack of resistance at Year 2. CONCLUSIONS: Long-term telbivudine efficacy in Taiwanese patients was comparable to the GLOBE 2303 study. A reduction in HBV DNA levels by ≥5 log10 copies/mL at Week 24 represented the optimal cut-off point, which may predict favourable outcomes in patients with high baseline HBV DNA levels.

RESUMEN

The first wave of the coronavirus disease 2019 (COVID-19) outbreak in Taiwan occurred in May 2021. The risk for and severity of this disease vary and are highly dependent on personal habits and comorbidities. Moreover, the gut microbiome, which may be affected by diet, is highly susceptible with regard to the risk and severity of infectious diseases such as COVID-19. The relationship between dietary habits, nutritional status, and the effects of these factors on the immune system in the context of a global pandemic is an extremely important topic of immediate concern. Hence, the aim of this study was to explore the effect of vegetarian and non-vegetarian diets on COVID-19 severity during the pandemic. We conducted a retrospective evaluation of 509 patients who had been diagnosed with COVID-19 at a single medical center between May 2021 and August 2021. Patients were divided into three groups according to disease severity. For patients aged ≥65 years, COVID-19 symptom severity was statistically significantly and inversely associated with the adherence to a vegetarian diet (p = 0.013). Moreover, subgroup analysis results showed that older COVID-19 patients and those with a non-vegetarian diet had a higher risk of contracting critically severe COVID-19 [adjusted odds ratio (OR) = 5.434, p = 0.005]. Further research is needed to determine the effects of dietary habits on COVID-19 risk and severity during the global pandemic.

RESUMEN

Background: Since late 2019, there has been a global COVID-19 pandemic. To preserve medical capacity and decrease adverse health effects, preventing the progression of COVID-19 to severe status is essential. Jing-Si Herbal Tea (JSHT), a novel traditional Chinese medicine formula was developed to treat COVID-19. This study examined the clinical efficacy and safety of JSHT in patients with mild-to-moderate COVID-19. Methods: In this prospective cohort study, we enrolled 260 patients with mild-to-moderate COVID-19. The enrolled patients were divided into the JSHT (n = 117) and control (n = 143) groups. Both groups received standard management. The JSHT group was treated with JSHT as a complementary therapy. Results: Compared with standard management alone, JSHT combined with standard management more effectively improved the reverse transcription-polymerase chain reaction cycle threshold value, C-reactive protein level, and Brixia score in the adult patients with mild-to-moderate COVID-19, especially in the male and older patients (those aged ≥60 years). The results revealed that the patients treated with JSHT combined with standard management had 51, 70, and 100% lower risks of intubation, Medisave Care Unit admission, and mortality compared with those receiving standard management only. Conclusions: JSHT combined with standard management more effectively reduced the SARS-CoV-2 viral load and systemic inflammation and alleviated lung infiltrates in the patients with mild-to-moderate COVID-19, especially in the male and older patients (those aged ≥60 years). JSHT combined with standard management may prevent critical status and mortality in patients with mild-to-moderate COVID-19. JSHT is a promising complementary therapy for patients with mild-to-moderate COVID-19.

RESUMEN

PURPOSE: Psychological distress is common among patients with acute diseases and is associated with a poorer prognosis. Early detection and intervention are important for high-risk individuals. DESIGN AND METHODS: This retrospective study used the five-item Brief Symptom Rating Scale (BSRS-5) to assess psychological distress and evaluate whether proactive intervention may reduce distress levels among hospitalized patients in a single medical center in northern Taiwan. FINDINGS: Of the patients, 10.7% were found to have varying degrees of emotional distress (BSRS-5 ≥ 6). After providing integrated medical care for patients with psychological distress, the degree of stress decreased significantly (p < 0.001). These results were consistent across subgroups. PRACTICE IMPLICATIONS: The results highlight that proactive assessment and appropriate interventions may reduce patients' psychological distress during their course of hospitalization.

RESUMEN

This was a preliminary study on ultraviolet C (UVC) irradiation for SARS-CoV-2-contaminated hospital environments. Forty-eight locations were tested for SARS-CoV-2 using RT-PCR (33.3% contamination rate). After series dosages of 222-nm UVC irradiation, samples from the surfaces were negative at 15 s irradiation at 2 cm length (fluence: 81 mJ/cm2).

RESUMEN

BACKGROUND: Heme oxygenase one (HO-1) is considered a poor prognostic factor for survival in patients with severe-to-critical coronavirus disease (COVID-19), but the clinical correlation between heme catabolism biomarkers and COVID-19-related sepsis is unknown. The etiopathogenetic hypothesis of HO-1 response during sepsis in patients with poor prognosis should be clarified. This study aimed to investigate sepsis development within 48 h following moderate-to-critical COVID-19 and examined heme/HO-1 catabolism biomarkers associated with sepsis. We also studied the HO-1 and traditional prognostic factors for predicting survival in patients with COVID-19. METHODS: This retrospective observational study included patients unvaccinated for COVID-19 with moderate-to-critical COVID-19 (n = 156) who had been admitted to Taipei Tzu Chi Hospital in 2021. All COVID-19 patients were diagnosed by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase polymerase chain reaction. For analysis of heme catabolism in SARS-CoV-2-induced sepsis, we excluded patients with co-infection and severe anemia. Heme catabolism biomarkers were compared between groups of patients with COVID-19 and sepsis (sepsis) and those with COVID-19 without sepsis (no sepsis), and a control group comprising 100 healthy individuals. All clinical and laboratory data were collected retrospectively and blood specimens were collected from Biobank. Multivariable logistic regression analysis was used to compare all variables between the sepsis and no-sepsis groups. Cox regression analysis was used to determine predictors of survival in patients with COVID-19. RESULTS: There were 71 and 85 patients with and without sepsis, respectively. Heme and HO-1 levels differed significantly between the sepsis, no sepsis, and control groups. In multivariate analysis, confusion, blood urea nitrogen, respiration, blood pressure in patients aged > 65 years (CURB-65) (adjusted odds ratio [aOR] 5.331, 95% confidence interval [CI] 2.587-10.987; p < 0.001), albumin (aOR 0.139, 95% CI 0.003-0.636; p = 0.01), D-dimer (aOR 1.001, 95% CI 1.000-1.002; p = 0.032), and HO-1 (aOR 1.116, 95% CI 1.055-1.180; p < 0.001) were significantly associated with 48-h sepsis episodes after adjusting for other confounding factors. HO-1 levels were also significantly associated with 48-h Sequential Organ Failure Assessment Score (SOFA) scores. However, HO-1 did not significantly increase the hazard of in-hospital mortality in moderate-to-critical COVID-19 by Cox regression analysis. CONCLUSIONS: HO-1 levels increased with sepsis development within 48 h of admission for COVID-19 after adjusting for other risk factors, but no significant association was observed between HO-1 and COVID-19 mortality. We suppose that HO-1 may have protective effect in early sepsis, but further clinical multicenter prospective studies are needed.

RESUMEN

BACKGROUND & AIMS: Long-term treatment with entecavir resulted in durable virologic suppression and continued histologic improvement in nucleoside-naive chronic hepatitis B patients. Patients with advanced fibrosis or cirrhosis, who received long-term entecavir treatment, were evaluated for improvement in liver histology. METHODS: The study included a subset of patients from phase III and long-term rollover studies, who received entecavir for at least 3 years, had advanced fibrosis or cirrhosis, and evaluable biopsies at baseline and after long-term treatment. RESULTS: Ten patients had advanced fibrosis or cirrhosis at baseline (Ishak fibrosis score, ≥ 4). After approximately 6 years of cumulative entecavir therapy (range, 267-297 wk), all 10 patients showed improvement in liver histology and Ishak fibrosis score. The mean change from baseline in Ishak fibrosis and Knodell necroinflammatory scores were -2.2 and -7.6, respectively. A reduction in Ishak fibrosis score to 4 or less was observed for all 4 patients who had cirrhosis at baseline. CONCLUSIONS: Chronic hepatitis B patients with advanced fibrosis or cirrhosis demonstrated histologic improvement and reversal of fibrosis and cirrhosis after long-term treatment with entecavir.

RESUMEN

UNLABELLED: Current guidelines for management of chronic hepatitis B recommend treatment for patients presenting with elevated hepatitis B virus (HBV) DNA and alanine aminotransferase (ALT) >2 x upper limit of normal (ULN) or histological evidence of liver disease. Retrospective analyses have demonstrated that significant hepatic necroinflammation and fibrosis were present in a substantial proportion of patients with ALT 1 to 2 x ULN. To assess therapeutic efficacy in this clinical setting, we retrospectively examined treatment endpoints among the subset of nucleoside-naïve chronic hepatitis B (CHB) patients treated in phase 3 clinical trials of entecavir who had both screening and baseline serum ALT 1.3 to 2 x ULN. A total of 1347 patients were randomized to treatment with entecavir or lamivudine. Three hundred thirty-six patients, constituting 25% of the total study population, had screening and baseline ALT 1.3 to 2 x ULN. Clinically significant necroinflammation (Knodell necroinflammation score > or =7) was observed in 60% and 72% of hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients, respectively, whereas marked fibrosis (Ishak fibrosis score > or =4) was observed in 8% and 15% of HBeAg-positive and HBeAg-negative patients, respectively. Among entecavir-treated HBeAg-negative patients, the proportions of patients achieving histological improvement, HBV DNA <300 copies/mL, and ALT normalization were similar between patients with mildly elevated ALT and those with ALT >2 x ULN. However, entecavir-treated HBeAg-positive patients with mildly elevated ALT had lower response rates for histological improvement, HBV DNA less than 300 copies/mL, ALT normalization, and HBeAg seroconversion than those with ALT greater than 2 x ULN. CONCLUSION: This retrospective analysis demonstrated that HBeAg-negative CHB patients treated with entecavir responded similarly irrespective of baseline ALT level. However, HBeAg-positive patients with mildly elevated ALT responded less well to treatment with entecavir than did those with ALT greater than 2 x ULN.
