Abstract Background Anticoagulation therapy with vitamin K antagonists (e.g. warfarin) has recently been shown to contribute to the accelerated vascular calcification and worsening of renal function. Therefore, it is compelling to investigate the impact of different oral anticoagulants (OACs) on kidney function in non-valvular atrial fibrillation (NVAF) patients. Common co-morbidities in these patients are chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM), which might be presented at the OAC therapy initiation. Purpose The overall objective of the CALLIPER study was to evaluate the effectiveness and safety of the reduced dose rivaroxaban (15 mg once daily) as compared to warfarin in NVAF patients with renal dysfunction in real-world setting. In particular, we evaluated the risk of worsening of renal function in NVAF patients with CKD stage 3 and 4 at baseline (1 year prior to the cohort entry). Additionally, a sub-group analysis of patients with T2DM was performed. We defined worsening of renal function as progression to CKD stage 5, kidney failure or need for dialysis. Methods Individual level data of warfarin- and rivaroxaban-naïve NVAF patients from the MarketScan database for the years 2012 through 2017 were used. Patients with moderate-to-severe CKD (stage 3 and 4) were included in the study cohort and were followed until progression to CKD 5, kidney failure or dialysis, OAC discontinuation/switch, insurance disenrollment or end of data availability. A comparative analysis evaluating the hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs) under warfarin or rivaroxaban treatment was performed using Cox regression. A stabilized inverse probability of treatment weighting was used to adjust for imbalances in baseline patient characteristics. Results We identified 5,906 warfarin- and 1,466 rivaroxaban-naïve patients with NVAF and CKD stage 3 and 4, of which 60% were male, median (25–75% range) age=79 (71- 84) years, CHADS2 score=2.67 (2.00- 3.50), CHA2DS2-VASc score=4.43 (3.40–5.62), modified HAS-BLED score=3.00 (2.40 - 3.65). T2DM was present in more than 50% of patients (Table), namely, in 3,160 warfarin- and 746 rivaroxaban-users. Hazard ratios and 95% CI for worsening of renal function were evaluated at 0.53 (0.35; 0.78) in the main cohort and 0.50 (0.30; 0.83) in the T2DM sub-group, meaning that rivaroxaban was associated with a significant 47% and 50% risk reduction of this outcome in NVAF patients with CKD stage 3 and 4 with and without T2DM, respectively. Conclusion The reduced dose of rivaroxaban has appeared to lower significantly the risk of worsening of renal function versus warfarin in NVAF patients with CKD stage 3 and 4 present at the OAC therapy initiation. The conclusion holds true for the patients with the co-morbid T2DM. This evidence was generated by the CALLIPER study using one of the largest US administrative claims database.

Inflammatory State

Coronavirus disease 19 is a global pandemic which infects over millions of people worldwide in a limited time and changes the lifestyle, clinical spectrum lies from asymptomatic infection to pneumonitis with cardiorespiratory failure and finally death. Higher mortality occurs in senior and who are suffering from co-morbidities like chronic kidney disease, (HTN) hypertension, (DM TYPE II) diabetes mellitus or (CVD) cardiovascular diseases. However, rather than normal individuals, patients with chronic kidney disease (CKD) are under higher risk for infections. The chronic systemic inflammatory state is a significant cause for morbidity and mortality in CKD patients. The objective of this review is to discuss the pathogenesis of COVID-19 in CKD, changes observed in the immune system of CKD patients, COVID-19 infections risk in CKD and therapeutic approach of COVID-19 in CKD patients. From the standpoint of frequent renal co-morbidities in covid19 patients, renal complications were explored in covid19 patients received at level 2 tertiary care Santosh Hospital, Ghaziabad, U.P. Delhi-NCR India during March to August 2020 as per the protocol of Nephrology Society of India. Relevant clinical trials were reviewed in support. Meta-analysis and clinical trials are covered in this review study. Duplicate studies are not taken into account. The outcome of the studies shows that CKD patients are more prone to COVID-19. CKD patients are more likely infected with COVID-19 virus. Whereas in intensive care, CKD occurs more frequent than DM type II and CVD. So,COVID-19 pathogenesis in CKD patients, risk of COVID-19, immunologic changes and therapy COVID-19 in CKD can add support in the effective management of COVID-19.

Abstract Introduction Chronic kidney disease (CKD) is associated with an elevated thromboembolic and bleeding risk in atrial fibrillation (AF) patients, so the decision of antithrombotic therapy is a challenge. Purpose To analyze mortality, embolic and bleeding events in patients with advanced CKD and AF. Methods Multicentric retrospective registry on patients with AF and advanced CKD (CKD-EPI <30 mL/min/1.73 m2). For death, multivariable Cox regression analysis was developed. For embolic and bleeding events, competing-risks regression based on Fine and Gray's proportional subhazards model was performed, being death the competing event Results We analysed 405 patients with advanced CKD and newly diagnosed AF. 57 patients were not treated with antithrombotic therapy (14.1%), 80 only with antiplatelet/s (19.8%), 211 only with anticoagulation (52.1%), and 57 with anticoagulant plus antiplatelet/s (14.1%). During a follow-up of 4.6±2.5 years, 205 died (50.6%), 34 had embolic events (8.4%) and 85 had bleeding outcomes (21.0%). Bleeding event rate was significantly lower in patients without antithrombotic therapy (Figure). After multivariate analysis, anticoagulant treatment was associated with higher bleeding rates, without differences in mortality or embolic events (Table). Conclusion Anticoagulation therapy was associated with a significant increase in bleeding events in patients with advanced CKD and newly diagnosed AF. None of the antithrombotic therapy regimens resulted in lower embolic events rate neither benefit in mortality. Funding Acknowledgement Type of funding source: Private grant(s) and/or Sponsorship.
