Bayesian network Meta-analysis was performed to evaluate the efficacy and safety of different Chinese patent medicines in the treatment of dilated cardiomyopathy. The PubMed, EMbase, Cochrane Library, CNKI, Wanfang, and VIP were searched for the randomized controlled trial(RCT) from the inception to May 2023. The quality of the included RCT was evaluated by the Cochrane risk of bias assessment tool, and the data were analyzed by RStudio 3.6.3 calling the "gemtc" package. A total of 96 RCTs involving 8 452 patients, 11 Chinese patent medicines, and 8 outcome indicators were included. Network Meta-analysis is described as follows.(1)In terms of improving clinical total effective rate, except Yixinshu Capsules + conventional western medicine, Shexiang Baoxin Pills + conventional western medicine, and Xinshuai Mixture + conventional western medicine, the other Chinese patent medicines combined with conventional western medicine were superior to conventional western medicine alone, and Shenqi Yiqi Dropping Pills + conventional western medicine had the best effect.(2)In terms of improving left ventricular ejection fraction(LVEF), except Yixinshu Capsules + conventional western medicine and Shensong Yangxin Capsules + conventional western medicine, other Chinese patent medicines combined with conventional western medicine outperformed conventional western medicine alone, and Shexiang Baoxin Pills + conventional western medicine had the best effect.(3)In terms of reducing left ventricular end-diastolic dimension(LVEDD), Getong Tongluo Capsules + conventional western medicine, Xinshuai Mixture + conventional western medicine, Huangqi Mixture + conventional western medicine, Tongxinluo Capsules + conventional western medicine, Wenxin Granules + conventional western medicine, and Qili Qiangxin Capsules + conventional western medicine were better than conventional western medicine alone, and Wenxin Granules + conventional western medicine had the best effect.(4)There was no significant difference in reducing left ventricular end-systolic diameter(LVESD) between Chinese patent medicines combined with conventional western medicine and conventional western medicine alone.(5)In terms of improving 6-minute walking trail(6MWT), Yangxinshi Tablets + conventional western medicine, Yixinshu Capsules + conventional western medicine, Shenqi Yiqi Dropping Pills + conventional western medicine, Wenxin Granules + conventional western medicine, and Qili Qiangxin Capsules + conventional western medicine were superior to conventional western medicine alone, and Shenqi Yiqi Dropping Pills + conventional western medicine had the best effect.(6)In reducing brain natriuretic peptide(BNP), Xinshuai Mixture + conventional western medicine ourperformed conventional western medicine alone.(7)In reducing hypersensitive C-reactive protein(hs-CRP), Shenqi Yiqi Dropping Pills + conventional western medicine, Qili Qiangxin Capsules + conventional western medicine outperformed conventional western medicine alone, and Qili Qiangxin Capsules + conventional western medicine had the best effect.(8)In terms of safety, adverse reactions were reported in both groups. In conclusion, Chinese patent medicine combined with conventional western medicine were more effective in the treatment of dilated cardiomyopathy. The combinations relieve clinical symptoms and improve cardiac function indexes, and thus can be used according to the patients' conditions in clinical practice. However, limited by the quality and sample size of the included studies, the conclusion remains to be verified by multi-center, large-sample, and high-quality RCT in the future.

PURPOSE: Cardiotoxicity is a serious late complication of breast cancer treatment. Individual treatment risk of specific drugs has been investigated. However, studies on the evaluation of the composite risk of chemotherapeutic agents are limited.METHODS: We retrospectively analyzed the medical records of breast cancer patients who received adjuvant treatment and had available serial echocardiography results. Patients were assigned to subgroups based on chemotherapy containing anthracyclines (A), anthracyclines and taxanes (A+T), and radiotherapy (RT). The development of cardiac disease and serial ejection fraction (EF) were reviewed. EF decline up to 10% from baseline was considered grade 1 cardiotoxicity and EF decline >20% or absolute value < 50% was considered grade 2 cardiotoxicity. The most recent medical records and echocardiography results over 1 year of chemotherapy completion were also reviewed. Late cardiotoxicity was defined as a lack of recovery of EF decline or aggravated EF decline from baseline.RESULTS: In total, 123 patients were evaluated. A small reduction in EF was observed after chemotherapy in both chemotherapy groups. There were no significant differences between groups A and A+T in EF decline following chemotherapy. We could not find any differences in composite risk between the chemotherapy groups and the RT group during follow-up. Late cardiotoxicity was seen in 15.45% of patients. During follow-up, three patients were diagnosed with dilated cardiomyopathy.CONCLUSION: There was no significant composite risk elevation following adjuvant treatment of breast cancer. However, late cardiotoxicity was considerable and further research in this direction is necessary.

Graves disease (GD) can lead to complications such as cardiac arrhythmia and heart failure. Although dilated cardiomyopathy (DCMP) has been occasionally reported in adults with GD, it is rare in children. We present the case of a 32-month-old boy with DCMP due to GD. He presented with irritability, vomiting, and diarrhea. He also had a history of weight loss over the past few months. On physical examination, he had tachycardia without fever, a mild diffuse goiter, and hepatomegaly. The chest radiograph showed cardiomegaly with pulmonary edema, while the echocardiography revealed a dilated left ventricle with an ejection fraction (EF) of 28%. The thyroid function test (TFT) showed elevated serum T3 and decreased thyroid stimulating hormone (TSH) levels. The TSH receptor autoantibody titer was elevated. He was diagnosed with DCMP with GD; treatment with methylprednisolone, diuretics, inotropics, and methimazole was initiated. The EF improved after the TFT normalized. At follow-up several months later, although the TFT results again showed evidence of hyperthyroidism, his EF had not deteriorated. His cardiac function continues to remain normal 1.5 months after treatment was started, although he still has elevated T3 and high TSH receptor antibody titer levels due to poor compliance with drug therapy. To summarize, we report a young child with GD-induced DCMP who recovered completely with medical therapy and, even though the hyperthyroidism recurred several months later, there was no relapse of the DCMP.

OBJECTIVETo investigate the effects of recombinant human growth hormone (rhGH) on the morphology and function of the left cardiac ventricle in young rats with dilated cardiomyopathy (DCM), and to evaluate the efficacy and safety of rhGH in the treatment of DCM.

METHODSSixty male Sprague-Dawley rats were randomly and equally assigned to control group, DCM group, and rhGH group. Furazolidone (0.25 mg/g) was given by gavage for 12 weeks to prepare the DCM model. Rats in the rhGH group received an intraperitoneal injection of rhGH (0.15 U/kg) once per day for 12 weeks, while rats in the DCM group received an equal volume of normal saline instead. Rats in the control group did not receive any treatment. Cardiac indices, serum biochemical parameters, hemodynamic indices, cardiac histopathological changes, and levels of myocardial collagen fibrils in each group were determined using Doppler echocardiography, enzyme-linked immunosorbent assay, multi-channel physiological recorder, light and electron microscopy, and picrosirius red staining plus polarization microscopy, respectively.

RESULTSCompared with the control group, rats in the DCM group had significantly increased cardiac chamber size, significantly reduced ventricular wall thickness, and significantly decreased fractional shortening (FS) and ejection fraction (EF) (P<0.05). Rats in the rhGH group had significantly improved cardiac chamber size, ventricular wall thickness, FS, and EF compared with the DCM group (P<0.05). Those indices in the rhGH group were similar to those in the control group (P>0.05). There were significant differences in serum biochemical parameters and hemodynamic indices between the DCM and control groups (P<0.05). Compared with the DCM group, the rhGH group had significantly improved serum biochemical parameters and hemodynamic indices (P<0.05). Those indices in the rhGH group were similar to those in the control group (P>0.05), except for the levels of insulin-like growth factor-1 and insulin-like growth factor-binding protein-3. The DCM group had a significantly higher collagen type I/collagen type III (Col I/Col III) ratio in the myocardium than the control group (P<0.05), and there was no significant difference in the Col I/Col III ratio between the control and rhGH groups (P>0.05).

CONCLUSIONSrhGH plays a certain role in improvement in the morphology and function of the left cardiac ventricle in young rats with DCM.

OBJECTIVE: Astragaloside is a simple substance of saponin and the active constituent of astragali. It was reported that the astragaloside exerted therapeutical eff ect on viral myocarditis and dilated cardiomyopathy. The purpose of this study was to investigate the effect of astragaloside on TL1A expression in viral myocarditis. METHODS: A total of 100 BALB/c mice were randomly divided into 6 groups: the normal control group (group A, n=10), the high-dose control group (group B, n=10), the myocarditis control group (group C, n=20), the low-dose group (group D, n=20), the middle-dose group (group E, n=20) and the high-dose group (group F, n=20). Mice in group A and group B were injected intraperitoneally with 0.1 mL EMEM solution, while mice in group C, D, E and F were treated with 0.1 mL of 1×102 TCID50 CVB3 (diluted in EMEM). Then, mice in group A and group B were treated with carboxymethycellulose solution and 9% astragaloside for 1 week, respectively. At the same time, mice in group C, D, E and F were treated with sodium carboxymethycellulose solution, 1% [0.07 g/(kg.d)], 3% [0.2 g/(kg.d)] and 9%[0.6 g/(kg.d)] astragaloside for 1 week, respectively. After 14 days, the mice were sacrificed and their hearts were collected. The expression levels of TL1A mRNA and protein in the myocardium were examined by RT-PCR and immunohistochemistry, respectively. RESULTS: There was no death in the group A and B. The mortality in the group C, D, E and F was 45% (9/20), 30% (6/20), 25% (5/20) and 10% (2/20), respectively. Compared with the group C, the mortality in the group F was significantly decreased (P<0.05), but there no significant difference in mortality between the group C and the group D or E (P>0.05). There was no any pathological lesion in the group A and B. The TL1A mRNA and protein expression in the myocardium of mice in the group A and B was at low level, with no difference between them (P>0.05). Compared with the group A, the expression levels of TL1A mRNA and protein in the group C were markedly up-regulated (P<0.01), which was dramatically attenuated by the intervention of astragaloside at high dosage (the group F, P<0.01) but not at low (the group D) or middle-dosage (the group E) (P>0.05). CONCLUSION Astragaloside may play a pivotal role in protection of the heart injury in viral myocarditis by suppressing the expression of TL1A.

An 82-yr-old man was presented with fever and cough accompanied by generalized erythematous rash. He had taken mexiletine for 5 months, as he had been diagnosed with dilated cardiomyopathy and ventricular arrhythmia. Laboratory studies showed peripheral blood eosinophilia and elevated liver transaminase levels. Chest radiographs showed multiple nodular consolidations in both lungs. Biopsies of the lung and skin lesions revealed eosinophilic infiltration. After a thorough review of his medication history, mexiletine was suspected as the etiologic agent. After discontinuing the mexiletine and starting oral prednisolone, the patient improved, and the skin and lung lesions disappeared. Subsequently, mexiletine was confirmed as the causative agent based on a positive patch test. Drug-induced hypersensitivity syndrome is a severe adverse reaction to drugs and results from treatment with anticonvulsants, allopurinol, sulfonamides, and many other drugs. Several cases of mexiletine-induced hypersensitivity syndrome have been reported in older Japanese males with manifestation of fever, rash, peripheral blood eosinophilia, liver dysfunction without other organ involvement. Here, we report a case of mexiletine-induced hypersensitivity syndrome which presented as eosinophilic pneumonia in a Korean male.
