Clinical profile of patients with prosthetic heart valve thrombosis undergoing fibrinolytic therapy and NYHA class as a predictor of outcome

Background: Prosthetic heart valve thrombosis (PHVT) is a potentially fatal complication of heart valve replacement with mechanical prostheses mainly due to thrombosis.Aim: The study aimed to evaluate the clinical profile of the patients presenting with PHVT undergoing fibrinolytic therapy and analyzing patients with respect to New York Heart Association (NYHA) functional class on presentation and its association with outcome of fibrinolytic therapy.Settings & design: This was prospective, observational study conducted from June, 2016 to April, 2017. Total 133 patients with prosthetic heart valve thrombosis were included. Materials and methods: Routine blood investigations included complete hemogram, liver and renal function tests. Prothrombin time with INR was done on admission. The diagnosis of PHVT was assessed by fluoroscopy and/or echocardiography (transthoracic/transesophageal). Follow-up at 6 months was scheduled for all patients.Statistical analysis: Parametric values between two groups were performed using the independent sample t-test or chi-square test, as appropriate. Univariate and multivariate logistic regression was used to find out factors associated with outcome.Results: All patients received fibrinolytic therapy in which 108 (81.2%) were treated with streptokinase and 25 (18.8%) were treated with urokinase. On presentation, 48.9% patients were in NYHA class III, 41.4% in NYHA class IV and 9.77% in NYHA class II. Fibrinolytic therapy was successful in 105 patients (78.9%) and it failed in 28 patients (21.1%). Mortality in NYHA class II was 0%, NYHA class III was 4.6% and in NYHA class IV was 23.6%. During 6 months follow up prosthetic heart valve thrombosis recurred in 12 (11.43%) patients.Conclusion: From our single centre experience, fibrinolytic therapy is fairly effective first line therapy for prosthetic heart valve thrombosis and NYHA functional class on presentation can predict the outcome of fibrinolytic therapy

Study of usefulness of speckle-tracking echocardiography in detecting left ventricular dysfunction among adult cancer patients undergoing chemotherapy

Objective: Cancer treatment-related cardiac dysfunction (CTRCD) is a significant concern for patients undergoing chemotherapy. The aim of the present study was to study the accuracy and value of longitudinal strain in prediction of left ventricular dysfunction (LVD) in cancer patients undergoing cancer therapy. Methods: This was a prospective observational study conducted among 183 adult patients undergoing chemotherapy between 2018 and 2020. Patients with congenital or acquired valvular disease, prior myocardial infarction, coronary revascularization, or cardiac surgery were excluded. The patients were evaluated using a detailed history, clinical examination and echocardiography at baseline, 1 month, 3 months, and 6 months after chemotherapy. Speckle-tracking strain analysis was used to evaluate left ventricular (LV) global longitudinal strain (GLS), circumferential strain (GCS), and radial strain (GRS). LVD was defined as >15% decrease in GLS, GCS, or GRS from baseline to 6 months. Accuracy of longitudinal strain in prediction of LVD was studied using ROC analysis. Results: Of the 183 patients, 59% were male, and 54.1% were between 46-60 years of age. Breast cancer was the most common malignancy (10.9%). The most common chemotherapy regimen was doxorubicin + paclitaxel (9.9%). At baseline, the mean GLS, GCS, and GRS were -18.6 (1.03)%, -20.4 (1.11)%, and 39.9 (6.09)%, respectively. At the 6-month follow-up, 27 (14.8%) patients had LVD. The incidence of LVD was higher (51.48%) in patients who received doxorubicin-containing regimens compared to non-doxorubicin-containing regimens (P <0.0001). GLS has good accuracy in prediction of LVD at 6 months of follow-up (88.37%). Conclusions: The incidence of LV dysfunction was higher (51.48%) in patients who received doxorubicin-containing regimens. GLS is different in LVD vs non LVD and the accuracy of GLS is more in prediction of LVD development during 6-month follow-up (88.37%)

Src Dependent Pancreatic Acinar Injury Can Be Initiated Independent of an Increase in Cytosolic Calcium

Several deleterious intra-acinar phenomena are simultaneously triggered on initiating acute pancreatitis. These culminate in acinar injury or inflammatory mediator generation in vitro and parenchymal damage in vivo. Supraphysiologic caerulein is one such initiator which simultaneously activates numerous signaling pathways including non-receptor tyrosine kinases such as of the Src family. It also causes a sustained increase in cytosolic calcium- a player thought to be crucial in regulating deleterious phenomena. We have shown Src to be involved in caerulein induced actin remodeling, and caerulein induced changes in the Golgi and post-Golgi trafficking to be involved in trypsinogen activation, which initiates acinar cell injury. However, it remains unclear whether an increase in cytosolic calcium is necessary to initiate acinar injury or if injury can be initiated at basal cytosolic calcium levels by an alternate pathway. To study the interplay between tyrosine kinase signaling and calcium, we treated mouse pancreatic acinar cells with the tyrosine phosphatase inhibitor pervanadate. We studied the effect of the clinically used Src inhibitor Dasatinib (BMS-354825) on pervanadate or caerulein induced changes in Src activation, trypsinogen activation, cell injury, upstream cytosolic calcium, actin and Golgi morphology. Pervanadate, like supraphysiologic caerulein, induced Src activation, redistribution of the F-actin from its normal location in the sub-apical area to the basolateral areas, and caused antegrade fragmentation of the Golgi. These changes, like those induced by supraphysiologic caerulein, were associated with trypsinogen activation and acinar injury, all of which were prevented by Dasatinib. Interestingly, however, pervanadate did not cause an increase in cytosolic calcium, and the caerulein induced increase in cytosolic calcium was not affected by Dasatinib. These findings suggest that intra-acinar deleterious phenomena may be initiated independent of an increase in cytosolic calcium. Other players resulting in acinar injury along with the Src family of tyrosine kinases remain to be explored. © 2013 Mishra et al

Multiple modalities in treating pediatric pure red cell aplasia: A case series

Objective: To analyze the clinical profile and available treatment modalities in pure red cell aplasia (PRCA). Methodology: Retrospective analysis of children diagnosed with PRCA from 2014 to 2019. Clinical profile, investigations, and treatment details were analyzed. Results: Eleven patients were diagnosed with PRCA; 5 congenital (mean age: 8.5 months) and 6 acquired (mean age: 13.5 years). In the congenital group, 5 had Diamond Blackfan Anemia (DBA); genetically proven in 3. Children with DBA recieved steroid trial for a mean duration of 9 months. Four patients required chronic transfusion, while one (with RPS 19 mutation) responded to steroids. Of the six in the acquired group, two each had transient erythroblastopenia of childhood, and parvovirus B19 infection. Two patients with PRCA post-allogenic HSCT (major ABO incompatibility) responded to multiple modalities of treatment with satisfactory results up to day +89 post-transplant. Conclusion: PRCA is a multi-faceted disease with many clinico-hematological presentations. We describe varied outcomes in children with various forms of PRCA receiving multiple treatment modalities

Incidence and predictors of development of new onset hypertension post COVID-19 disease

Aims: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus) affects vital organs and causes vascular injury. There are concerns that this injury may have long-term consequences on the cardiovascular system after recovery from COVID-19. We investigated the incidence and predictors of new-onset hypertension at 1-year follow-up post-COVID-19 disease. Methods: In this prospective observational study, 393 patients hospitalised and diagnosed with COVID-19 disease at a tertiary cardiac care hospital during 27th March 2021 to 27th May 2021. Eligible 248 patients whose baseline characteristics, laboratory findings, treatment and outcome data were received systematically. Patients were followed up at 1 year of COVID-19 disease recovery. Results: We found that 32.3% of the population had new onset of hypertension at 1 year follow-up post-COVID-19 disease recovery. More hypertensive patients had severe computed tomography (CT) score severity (28.7 vs 14.9%; P 0.02). More number of patients in the hypertensive group were treated with steroids (73.8% vs 39%; p < 0.0001) during hospital stay. In-hospital complications were higher (12.5 vs 4.2%; P 0.03) in the hypertensive group. Patients who developed new-onset hypertension had statistically significantly higher baseline values of serum ferritin and C-reactive protein (CRP) (P 0.02 and 0.03 respectively). Vascular age was found 12.5 ± 3.96 years more than chronological age in hypertensive patients. Conclusion: New onset of hypertension was detected in 32.3% of patients at one-year follow-up post-COVID-19 disease recovery. Severe inflammation at the time of admission and severe CT severity score were associated with the development of new onset of hypertension on follow-up

Is there an association of intracardiac mass with high urate level? AIM-HUL study

Context: Hyperuricemia is associated with idiopathic left atrium/left ventricular clot, and its association with other intracardiac tumors is not clear. Aim: The study aimed to establish if there is an association of intracardiac mass with high urate level. Settings and Design: This prospective study included 440 individuals, of which 330 were consecutive all comers with intracardiac mass detected on echocardiography from June 2016 to December 2017, who were compared with 110 randomly selected healthy controls undergoing echocardiography during the same without intracardiac mass in a ratio of 3:1. Materials and Methods: Imaging modalities such as transesophageal echocardiography, cardiac computerized tomography, and/or cardiac magnetic resonance imaging were done to analyze the intracardiac mass. Both the groups were analyzed for serum uric acid (SUA) levels at the time of detection of intracardiac mass. Statistical Analysis Used: Univariate analysis was done for continuous variables using Student's t-test, whereas the Chi-square test was used for the categorical data. Logistic regression analysis was performed with the presence of a mass with SUA as the dependent variable. Results: Among a total of 440 patients, 330 were cases and 110 were controls with the mean age of 47.52 ± 16.02 years (18–77 years) versus 45.23 ± 14.10 (18–73 years) years with male:female ratio of nearly 3:2 in both the groups. Mean SUA in cases was significantly higher than controls (7.60 ± 0.93 vs. 4.52 ± 1.20 mg%) (P < 0.001 with 7.6 [95% confidence interval (CI): 7.5–7.7] and 4.52 [95% CI: 4.3–4.74]) with linear logistic regression coefficient of 0.64. There was no significant difference in SUA levels among different types of intracardiac mass (P = 0.31). Conclusion: Hyperuricemia is associated with all comers of intracardiac mass with a regression coefficient of 0.64 irrespective of the nature of mass

Successful topical treatment of human biofilms using multiple antibiotic elution from a collagen-rich hydrogel

Abstract Chronic non-healing wounds significantly strain modern healthcare systems, affecting 1–2% of the population in developed countries with costs ranging between $28.1 and$96.8 billion annually. Additionally, it has been established that chronic wounds resulting from comorbidities, such as peripheral vascular disease and diabetes mellitus, tend to be polymicrobial in nature. Treatment of polymicrobial chronic wounds with oral and IV antibiotics can result in antimicrobial resistance, leading to more difficult-to-treat wounds. Ideally, chronic ulcers would be topically treated with antibiotic combinations tailored to the microbiome of a patient’s wound. We have previously shown that a topical collagen-rich hydrogel (cHG) can elute single antibiotics to inhibit bacterial growth in a manner that is nontoxic to mammalian cells. Here, we analyzed the microbiology of cultures taken from human patients diagnosed with diabetes mellitus suffering from chronic wounds present for more than 6 weeks. Additionally, we examined the safety of the elution of multiple antibiotics from collagen-rich hydrogel in mammalian cells in vivo. Finally, we aimed to create tailored combinations of antibiotics impregnated into cHG to successfully target and treat infections and eradicate biofilms cultured from human chronic diabetic wound tissue. We found that the majority of human chronic wounds in our study were polymicrobial in nature. The elution of multiple antibiotics from cHG was well-tolerated in mammalian cells, making it a potential topical treatment of the polymicrobial chronic wound. Finally, combinations of antibiotics tailored to each patient’s microbiome eluted from a collagen-rich hydrogel successfully treated bacterial cultures isolated from patient samples via an in vitro assay

Epidemiological and clinical characteristics of pulmonary arterial hypertension in Indian patients: A hospital-based observational study

Context: Pulmonary hypertension (PH) is a condition characterized by an increase in pulmonary artery pressure, leading to morbidity and poor survival. In India, the high prevalence of certain diseases contributes to the burden of PH. To address this, this study provides epidemiological data and clinical characteristics of pulmonary artery hypertension. Materials and Methods: A cross-sectional study was conducted at a tertiary cardiac care hospital, recruiting 964 patients with severe pulmonary arterial hypertension (PAH). Patient data were obtained through a detailed history and physical examination, including 12-lead electrocardiogram, two-dimensional echocardiography, coronary angiography, right heart catheterization, and hematological and serological investigations. Results: The majority of patients (28.94%) were in the age group of 31–40 years, with a female preponderance in PAH disease. Idiopathic PAH (IPAH) was the most common type, accounting for 69.78% of all cases. The most common comorbid conditions were hypertension (48.55%) and Type-2 diabetes mellitus (44.81%). Dyspnea on exertion (98.34%) and edema of extremities (91.18%) were the most common symptoms. The mean survival rate was 50.98 months, with Type 1 PAH having the worst survival rate of 47.56 months. The statistical analysis showed a significant association between smoking and PAH. Conclusion: This study provides epidemiological data and clinical characteristics of PAH patients in India, emphasizing the need for early diagnosis, prompt management, and smoking cessation programs. The high prevalence of IPAH and female preponderance was also observed in this study. These findings can help in the development of targeted interventions and management strategies for PH patients in India
