ABSTRACT
BACKGROUND: Postcardiac injury syndrome (PCIS) is an easy-to-miss diagnosis, but it is not an uncommon complication. The phenomenon of echocardiography (ECHO) showing both severe pulmonary arterial hypertension (PAH) and severe tricuspid regurgitation (TR) is indeed rare in PCIS after extensive radiofrequency ablation. CASE PRESENTATION: A 70-year-old male was diagnosed with persistent atrial fibrillation. The patient received radiofrequency catheter ablation due to his atrial fibrillation being refractory to antiarrhythmic drugs. After the anatomical three-dimensional models were created, ablations were performed on the left and right pulmonary veins, roof linear and bottom linear of the left atrium, and the cavo-tricuspid isthmus. The patient was discharged in sinus rhythm (SR). After 3 days, he was admitted to the hospital for gradually worsening dyspnea. Laboratory examination showed a normal leukocyte count with an increased percentage of neutrophils. The erythrocyte sedimentation rate, C-reactive protein concentration, interleukin-6, and N-terminal pro-B-type natriuretic peptide were elevated. ECG exhibited SR, V1-V4 of precordial lead P-wave amplitude which was increased but not prolonged, PR segment depression, and ST-segment elevation. Computed tomography angiography of the pulmonary artery revealed that the lung had scattered high-density flocculent flakes and a small amount of pleural and pericardial effusion. Local pericardial thickening was seen. ECHO showed severe PAH with severe TR. Diuretics and vasodilators did not relieve the symptoms. Tumors, tuberculosis, and immune system diseases were all excluded. Considering the patient's diagnosis of PCIS, the patient was treated with steroids. The patient recovered on the 19th day post ablation. The patient's condition was maintained until 2 years of follow-up. CONCLUSIONS: The phenomenon of ECHO showing severe PAH with severe TR is indeed rare in PCIS. Due to the lack of diagnostic criteria, such patients are easily misdiagnosed, leading to a poor prognosis.

BACKGROUND AND AIM: Currently, the number of patients with coronavirus disease 2019 (COVID-19) infection is increasing rapidly worldwide. In this study, we aimed to assess whether diabetes mellitus (DM) would increase the risk of severe infection and death in patients with COVID-19. METHODS: We systematically searched the PubMed, Web of Science, MedRxiv and COVID-19 academic research communication platform for studies reporting clinical severity and/or overall mortality data on DM in patients with COVID-19 published up to July 10, 2020. The primary outcome was to compare the severe infection rate and mortality rate in COVID-19 patients with and without DM, and to calculate the odds ratio (OR) and 95% confidence interval (CI). RESULTS: A total of 76 studies involving 31,067 patients with COVID-19 were included in our meta-analysis. COVID-19 patients with DM had higher severe infection and case-mortality rates compared with those without DM (21.4 vs. 10.6% and 28.5 vs. 13.3%, respectively, all p <0.01). COVID-19 patients with DM were at significantly elevated risk of severe infection (OR = 2.38, 95% CI: 2.05-2.78, p <0.001) and mortality (OR = 2.21, 95% CI: 1.83-2.66, p <0.001). CONCLUSION: DM is associated with increased risk of severe infection and higher mortality in patients with COVID-19. Our study suggests that clinicians should pay more attention to the monitoring and treatment of COVID-19 patients with DM.

OBJECTIVE: To investigate the prognostic value of serum amyloid A (SAA) in the patients with Corona Virus Disease 2019 (COVID-19). METHODS: The medical data of 89 COVID-19 patients admitted to Renmin Hospital of Wuhan University from January 3, 2020 to February 26, 2020 were collected. Eighty-nine cases were divided into survival group (53 cases) and non-survival group (36 cases) according to the results of 28-day follow-up. The SAA levels of all patients were recorded and compared on 1 day after admission (before treatment) and 3 days, 5 days, and 7 days after treatment. The ROC curve was drawn to analyze the prognosis of patients with COVID-19 by SAA. RESULTS: The difference of comparison of SAA between survival group and non-survival group before treatment was not statistically significant, Z1 = - 1.426, P = 0.154. The Z1 values (Z1 is the Z value of the rank sum test) of the two groups of patients at 3 days, 5 days, and 7 days after treatment were - 5.569, - 6.967, and - 7.542, respectively. The P values were all less than 0.001, and the difference was statistically significant. The ROC curve results showed that SAA has higher sensitivity to the prognostic value of 1 day (before treatment), 3 days, 5 days, and 7 days after treatment, with values of 0.806, 0.972, 0.861, and 0.961, respectively. Compared with SAA on the 7th day and C-reactive protein, leukocyte count, neutrophil count, lymphocyte count, and hemoglobin on the 7th day, the sensitivities were: 96.1%, 83.3%, 88.3%, 83.3%, 67.9%, and 83.0%, respectively, of which SAA has the highest sensitivity. CONCLUSION: SAA can be used as a predictor of the prognosis in patients with COVID-19.
