Atrial fibrillation (AF) is the most common arrhythmia and is responsible for significant disease burden worldwide. Current evidence has suggested that systemic inflammatory response plays a crucial role in the initiation, maintenance, and progression of AF. So, recent efforts have been directed in search of measurable inflammatory biomarkers as additional tools in severity and prognosis assessment of AF. A simple, and easily obtainable, inflammatory marker is the neutrophil-lymphocyte ratio (NLR), which has shown good performance in preliminary studies as a potential prognostic biomarker in patients with AF. In this work, we performed a thorough review of clinical studies that evaluated the role of C-reactive protein (CRP), interleukin-6 (IL-6), and NLR as predictors of outcomes in AF. We gave a particular emphasis on the NLR because it is a simpler, widely available, and inexpensive biomarker.

Coronavirus Infection

BACKGROUND: Despite the continuing global spread of the coronavirus infection COVID-19 caused by the SARS-CoV-2 coronavirus, the mechanisms of the pathogenesis of severe infections remain poorly understood. The role of comorbidity with other seasonal viral infections, including influenza, in the pathogenesis of the severe course of COVID-19 remains unclear. MATERIALS AND METHODS: The present study used sera left over from ongoing laboratory studies of patients with varying degrees of severity of COVID-19. The study was approved by the Local Ethics Committee of the Federal State Budgetary Scientific Institution IEM (protocol 3/20 from 06/05/2020). We studied 28 paired samples obtained upon admission of patients to the hospital and after 57 days of hospital stay. Paired sera of patients with COVID-19 were tested for antibodies to influenza A and B viruses. The presence of IgG antibodies specific to the SARS-CoV-2 spike (S) protein was studied using an enzyme-linked immunosorbent assay (ELISA). The serum concentration of C-reactive protein and the neutrophil-lymphocyte ratio on the day of hospitalization were also assessed. RESULTS: At least a 4-fold increase in serum IgG antibodies to SARS-CoV-2 S protein was found both in patients with PCR-confirmed SARS-CoV-2 infection and without PCR confirmation. It was shown that out of 18 patients with moderate and severe forms of COVID-19 infection, six of them showed at least a 4-fold increase in antibodies to influenza A/H1N1, in one to influenza A/H3N2 and in two cases to the influenza B. Laboratory data in these two groups were characterized by significant increases in serum C-reactive protein and neutrophil-lymphocyte ratio concentrations compared with the moderate COVID-19 group. CONCLUSIONS: Serological diagnostics can additionally detect cases of coronavirus infection when the virus was not detected by PCR. In moderate and severe cases of COVID-19, coinfections with influenza A and B viruses have been identified. The results obtained confirm the need for anti-influenza immunization during the SARS-CoV-2 pandemic. Influenza virus screening can significantly improve patient management because recommended antiviral drugs (neuraminidase inhibitors) are available.

Before And After

This study compared the effectiveness of the neutrophil/lymphocyte ratio (NLR) versus C-reactive protein (CRP) for evaluating the prognosis and degree of inflammation in patients with amputation for a diabetic foot ulcer (DFU). This study enrolled 56 patients with amputations for DFU with gangrene and compared the CRP levels and NLR measured before and after surgery. Overall, 24 patients (42%) died within 2 weeks postoperatively. Mortality increased with a preoperative/postoperative CRP difference ≤1.5 ( P < .001) and age 73 years or older ( P < .001). The postoperative NLR was lower than the preoperative value but was not significant as a prognostic or inflammatory marker ( P = .945). An increasing serum CRP level is a significant predictor of mortality. CRP and old age are reliable prognostic factors in patients with DFU.

Abstract Background There is increasing evidence that inflammatory biomarkers growth differentiation factor 15 (GDF-15) and neutrophil-lymphocyte ratio (NLR) appear to be associated with stroke and adverse cardiovascular events in patients with atrial fibrillation (AF). However, long-term impact of catheter ablation (CA) on GDF-15 and NLR is still unknown. Objective To evaluate the long-term change in GDF-15 and NLR after CA in paroxysmal AF patients. Methods A total of 58 paroxysmal AF patients were consecutively enrolled to perform CA. The inflammatory biomarkers GDF-15 and NLR were measured at baseline and 6-months postablation. Results All patients except one could complete 6-Months follow up. Fifty (87.7%) patients maintained sinus rhythm (SR group) and seven (12.3%) patients sustained AF recurrence (AFR group). No significant difference was noted in clinical and procedural characteristics between two groups (p>0.05), except mean fluoroscopy time (minutes 22±11.7 vs. 13±5.3, p=0.001) significantly longer in AFR than SR group. The GDF-15 (pg/ml 195±57 vs. 216±88, p=0.398), and NLR (% 1.8 (1.3–3) vs. 2.6 (1.4–3.4), p=0.395) were comparable at baseline in both SR and AFR groups respectively. At 6-months postablation, GDF-15 (pg/ml 133±41 vs. 195±57, p<0.001), and NLR (% 1.6 (1.1–2) vs. 1.8 (1.3–3), p=0.004) were significant deceased compared to baseline levels in SR group. However, GDF-15 (pg/ml 139±86 vs. 216±88, p=0.064), and NLR (% 1.6 (1.2–3) vs. 2.6 (1.4–3.4), p=0.398) biomarkers remained comparable to baseline level in AFR group (p>0.05) Conclusion Inflammatory biomarkers; GDF-15 and NLR significantly decreased at long-term on successful maintenance of sinus rhythm by CA in paroxysmal AF patients.
