Abstract
Genetic variations in the AGT gene play a significant role in controlling the plasma concentration of angiotensinogen (precursor protein of bioactive octapeptide angiotensin II) and the efficacy of antihypertensive drugs. In the current study, Tetra-Amplification Refractory Mutation System-Polymerase Chain Reaction (T-ARMS-PCR) was developed for genotyping of AGT rs699 T/C polymorphism and validated through Sanger DNA sequencing. Its efficiency was also tested using 474 human DNA samples [control, n = 181; cardiovascular disease (CVD) patients, n = 293]. Results showed that T-ARMS-PCR is superior to the commonly used PCR-Restriction Fragment Length Polymorphism (PCR-RFLP). Statistical analysis revealed that the AGT rs699 CC genotype is more prevalent in the CVD patient group (37% vs. 28%) and AGT rs699 C allele and CC genotype increased the risk of CVD by 1.4 and 1.9 fold, respectively. In summary, T-ARMS-PCR is the most suitable approach for quick and efficient genotyping of AGT rs699 T/C polymorphism in a large population in resource-limited countries, Furthermore, AGT rs699 T/C polymorphism is associated with the risk of CVD in the Punjabi Pakistani population.

Abstract
The low incidence of pediatric severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and the associated multisystem inflammatory syndrome (MIS-C) lack a unifying pathophysiological explanation, impeding effective prevention and therapy. Activation of the NACHT, LRR, and PYD domains-containing protein (NLRP) 3 inflammasome in SARS-CoV-2 with perturbed regulation in MIS-C, has been reported. We posit that, early age physiological states and genetic determinants, such as certain polymorphisms of renin-angiotensin aldosterone system (RAAS) molecules, promote a controlled RAAS hyperactive state, and form an evolutionary landscape involving an age-dependent erythropoietin (EPO) elevation, mediating ancestral innate immune defenses that, through appropriate NLRP3 regulation, mitigate tissue injury and pathogen invasion. SARS-CoV-2-induced downregulation of angiotensin-converting enzyme (ACE)2 expression in endothelial cells (EC), impairment of endothelial nitric oxide (NO) synthase (eNOS) activity and downstream NO bioavailability, may promote a hyperactive RAAS with elevated angiotensin II and aldosterone that, can trigger, and accelerate NLRP3 inflammasome activation, while EPO-eNOS/NO abrogate it. Young age and a protective EPO evolutionary landscape may successfully inhibit SARS-CoV-2 and contain NLRP3 inflammasome activation. By contrast, increasing age and falling EPO levels, in genetically susceptible children with adverse genetic variants and co-morbidities, may lead to unopposed RAAS hyperactivity, NLRP3 inflammasome dysregulation, severe endotheliitis with pyroptotic cytokine storm, and development of autoantibodies, as already described in MIS-C. Our haplotype estimates, predicted from allele frequencies in population databases, are in concordance with MIS-C incidence reports in Europeans but indicate lower risks for Asians and African Americans. Targeted Mendelian approaches dissecting the influence of relevant genetic variants are needed.

Transarterial chemoembolization (TACE) plus apatinib-combined therapy versus TACE alone in the treatment of intermediate to advanced hepatocellular carcinoma patients: A real-world study. Clin Res Hepatol Gastroenterol 2022; 46:101869. [PMID: 35108656 DOI: 10.1016/j.clinre.2022.101869] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 01/04/2022] [Accepted: 01/20/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Apatinib exhibits the synergistic effect with transarterial chemoembolization (TACE) though inhibiting the neoangiogenetic reaction caused by TACE. In this real-world study, we aimed to evaluate the efficacy and safety of TACE plus apatinib-combined therapy (ACT) in intermediate to advanced hepatocellular carcinoma (HCC) patients. METHODS Data from 168 intermediate to advanced HCC patients who received TACE alone (N = 49) or TACE plus ACT (N = 119) were extracted. Besides, ACT was defined as apatinib with or without other therapy, such as arsenic trioxide, microwave ablation and radioactive seed implantation. RESULTS In TACE plus ACT group, the median overall survival (OS) was 30 months (95% confidence interval (CI): 24-40 months) with 1-year, 3-year and 5-year OS rate of 84.0%, 41.2% and 21.5%, respectively. While in TACE group, the median OS was only 14 months (95%CI: 11-17 months) with 1-year, 3-year and 5-year OS rate of 55.1%, 18.4% and 16.1%, separately. By comparation, the OS was prolonged in TACE plus ACT group compared with TACE group (P<0.001). After adjusted by multivariate Cox's regression analysis, TACE plus ACT (vs. TACE) independently related to the longer OS (hazard ratio: 0.504, P = 0.001). In TACE plus ACT group, the most frequent adverse events included hand-foot syndrome (95.8%), hypertension (95.8%), fatigue (90.8%), albuminuria (85.7%), anorexia (79.0%), diarrhea (66.4%), myelosuppression (58.8%), nausea/vomiting (49.6%) and abdominal pain (39.5%), besides, no grade 4 adverse events and treatment-related death occurred. CONCLUSION TACE plus ACT is a promising treatment choice for the intermediate to advanced HCC patients.

Drug-eluting bead transarterial chemoembolization followed by apatinib is effective and safe in treating hepatocellular carcinoma patients with BCLC stage C. Clin Res Hepatol Gastroenterol 2022; 46:101859. [PMID: 34999249 DOI: 10.1016/j.clinre.2022.101859] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 12/14/2021] [Accepted: 12/31/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND The present study aimed to evaluate the efficacy and safety of drug-eluting beads transarterial chemoembolization (DEB-TACE) followed by apatinib in treating hepatocellular carcinoma (HCC) patients with Barcelona Clinic Liver Cancer (BCLC) stage C. METHODS Totally, 110 HCC patients with BCLC stage C treated with DEB-TACE followed by apatinib were consecutively enrolled. Treatment response (including complete response rate (CR), objective response rate (ORR) and disease control rate (DCR)), survival data (progression-free survival (PFS), overall survival (OS)), and adverse events were documented during the follow-up. RESULTS CR, ORR and DCR were 25.5%, 77.2% and 79.1% at 3 months, then were 29.1%, 59.1% and 71.0% at 6 months, respectively. Regarding survival, median PFS (95%CI) was 6.3 (5.0-7.7) months, meanwhile 1-year and 2-year PFS were 19.8% and 3.3%, respectively; median OS (95%CI) was 16.9 (10.2-23.7) months, then 1-year, 2-year and 3-year OS were 66.5%, 34.7% and 14.2%, respectively. Further subgroup analysis indicated that nodule size, Child-Pugh stage, Eastern Cooperative Oncology Group performance status score and level of portal vein invasion were negatively correlated with PFS or OS, which were further validated by univariate and multivariate Cox's regression analysis. Most adverse events by DEB-TACE and apatinib treatment were mild and well-tolerable. CONCLUSION DEB-TACE followed by apatinib is effective and safe in treating BCLC stage C HCC patients, indicating its role as an acceptable option in HCC management.
