Pak J Med Sci 2022; 38:302-309. [PMID: 35035444 PMCID: PMC8713206 DOI: 10.12669/pjms.38.1.4451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 07/17/2021] [Accepted: 07/28/2021] [Indexed: 11/15/2022] Open
Abstract
Objectives: To evaluate the effect of enteral nutrition on heart function, inflammatory markers and immune function in elderly patients with chronic heart failure and its clinical significance. Methods: Eighty patients with moderate and severe heart failure admitted to the Cardiology Intensive Care Unit (CCU) of Baoding First Central Hospital from May 2019 to May 2020 were included in this study and randomly divided into two groups: the experimental group and the control group, with 40 patients in each group. The experimental group was given enteral nutrition support therapy on the basis of conventional therapy for one month, while the control group was given restricted salt and water intake on the basis of conventional therapy, and patients were given free diet according to their wishes. The changes in heart function before and after treatment, changes in inflammatory factors such as TNF-a, CRP, IL-6, changes in levels of immunoglobulins such as IgA, IgM, and IgG, and the improvement of the performance status of the two groups were compared and analyzed. Results: After treatment, indicators such as BNP, LVEDD, LVEF and 6min walking distance in the experimental group were significantly improved compared with the control group, with statistically significant differences (p<0.05), and the levels of inflammatory factors such as TNF-a, CRP and IL-6 in the experimental group were significantly reduced compared with those in the control group (p=0.00). The levels of IgG, IgA, IgM and other immunoglobulins in the experimental group improved more significantly after treatment than those in the control group, with statistically significant differences (IgG, IgA, p=0.00; IgM, p=0.01). Moreover, the experimental group was significantly superior to the control group in the improvement rate of performance status score (ECOG) after treatment (p=0.04); The incidence of gastrointestinal adverse reactions in the experimental group was 20%, and that in the control group was 15%. No statistically significant difference can be observed in the gastrointestinal tolerance of both groups (p=0.56). Conclusions: Reasonable enteral nutrition boasts a variety of benefits for the recovery of elderly patients with chronic heart failure. With reasonable enteral nutrition, the heart function of elderly patients with chronic heart failure can be significantly improved, inflammatory factors can be reduced, immunity and performance status can be enhanced, and gastrointestinal tolerance can be ameliorated without obvious gastrointestinal reactions.

Activation of the Constitutive Androstane Receptor Inhibits Leukocyte Adhesiveness to Dysfunctional Endothelium. Int J Mol Sci 2021; 22:ijms22179267. [PMID: 34502180 PMCID: PMC8431649 DOI: 10.3390/ijms22179267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 08/17/2021] [Accepted: 08/23/2021] [Indexed: 11/17/2022] Open
Abstract
Leukocyte cell recruitment into the vascular subendothelium constitutes an early event in the atherogenic process. As the effect of the constitutive androstane receptor (CAR) on leukocyte recruitment and endothelial dysfunction is poorly understood, this study investigated whether the role of CAR activation can affect this response and the underlying mechanisms involved. Under physiological flow conditions, TNFα-induced endothelial adhesion of human leukocyte cells was concentration-dependently inhibited by preincubation of human umbilical arterial endothelial cells with the selective human CAR ligand CITCO. CAR agonism also prevented TNFα induced VCAM-1 expression, as well as MCP-1/CCL-2 and RANTES/CCL-5 release in endothelial cells. Suppression of CAR expression with a small interfering RNA abrogated the inhibitory effects of CITCO on these responses. Furthermore, CITCO increased interaction of CAR with Retinoid X Receptor (RXR) and reduced TNFα-induced p38-MAPK/NF-κB activation. In vivo, using intravital microscopy in the mouse cremasteric microcirculation treatment with the selective mouse CAR ligand TCPOBOP inhibited TNFα-induced leukocyte rolling flux, adhesion, and emigration and decreased VCAM-1 in endothelium. These results reveal that CAR agonists can inhibit the initial inflammatory response that precedes the atherogenic process by targeting different steps in the leukocyte recruitment cascade. Therefore, CAR agonists may constitute a new therapeutic tool in controlling cardiovascular disease-associated inflammatory processes.

Clin Rheumatol 2021; 40:4117-4126. [PMID: 34021842 DOI: 10.1007/s10067-021-05745-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 03/22/2021] [Accepted: 04/19/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVES We aimed to construct and validate a risk assessment model to identify risk factors for heart failure (HF) in patients with Takayasu's arteritis (TAK). METHODS Three hundred sixty-five patients with TAK were recruited in the East China Takayasu Arteritis Cohort from January 2012 to December 2019. Patients were assigned into training and validation sets following a 2:1 ratio according to the date of enrollment. Clinical characteristics were compared between heart failure (HF) and non-HF subgroups in the training set, and a risk assessment model for HF and its scoring algorithm was established based on logistic regression, which was tested in the validation set. RESULTS Among total of 74 (20.27%) TAK patients exhibited HF, and 55 cases (74.32%) were in the training set. The risk factors for HF of TAK patients included onset age >38 years, serum tumor necrosis factor (TNF)-α concentration >10 pg/ml, aortic valve involvement, coronary artery involvement, and pulmonary hypertension. We constructed the model without TNF-α (Model 1) and with TNF-α (Model 2). Patients in the training set with the score ≥ 3 appeared to be associated with an increased risk of HF with an area under curve (AUC) of 0.88 and 0.90 in Model 1 and Model 2 respectively. The AUC reached to 0.88 and 0.89 in the validation set that proved the accuracy of the model. CONCLUSIONS We presented a risk assessment model of HF in TAK, which may help clinicians alert the complication of HF in the patients with specifically cardiac impairments. Key Points • Heart failure was not rare in Chinese Takayasu's arteritis patients, and there were approximately 20% of patients with heart failure in ECTA cohort. • Cardiac involvements on echocardiography include pathological valvular and atrioventricular abnormalities. • The onset age >38 years, serum tumor necrosis factor (TNF)-α concentration >10 pg/ml, aortic valve involvement, coronary artery involvement, and pulmonary hypertension were risk factors for heart failure in Takayasu's arteritis patients. • We constructed the model without TNF-α (Model 1) and with TNF-α (Model 2). Patients with the risk assessment model score of ≥ 3 appeared to be associated with an increased risk of heart failure.

Abstract
Heart disease is a leading cause of death with unmet clinical needs for targeted treatment options. Tumor necrosis factor alpha (TNF-α) represents a master pro-inflammatory cytokine that plays an important role in many immunopathogenic processes. Anti-TNF-α therapy is widely used in treating autoimmune inflammatory disorders, but in case of patients with heart disease, this treatment was unsuccessful or even harmful. The underlying reasons remain elusive until today. This review summarizes the effects of anti-TNF-α treatment in patients with and without heart disease and describes the involvement of TNF-α signaling in a number of animal models of cardiovascular diseases. We specifically focused on the role of TNF-α in specific cardiovascular conditions and in defined cardiac cell types. Although some mechanisms, mainly in disease development, are quite well known, a comprehensive understanding of TNF-α signaling in the failing heart is still incomplete. Published data identify pathogenic and cardioprotective mechanisms of TNF-α in the affected heart and highlight the differential role of two TNF-α receptors pointing to the complexity of the TNF-α signaling. In the light of these findings, it seems that targeting the TNF-α pathway in heart disease may show therapeutic benefits, but this approach must be more specific and selectively block pathogenic mechanisms. To this aim, more research is needed to better understand the molecular mechanisms of TNF-α signaling in the failing heart.
