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.

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.

<b><i>Introduction:</i></b> Various inflammatory markers have been investigated for a prognostic role in patients with resectable pancreatic cancer. However, the value of preoperative platelet to lymphocyte ratio (PLR) remains controversial. We performed a systematic review and meta-analysis of PLR as a preoperative prognostic factor for resectable pancreatic cancer. <b><i>Material and Methods:</i></b> Systematic literature search was conducted for studies assessing PLR influence as a preoperative prognostic factor in resectable pancreatic cancer patients. Random-effects model was applied for pooling hazard ratios and 95% confidence intervals related to overall survival (OS) and disease-free survival (DFS). <b><i>Results:</i></b> Fourteen articles with 2,743 patients were included in the study. According to the analysis, high PLR had no correlation with decreased OS. Due to high heterogeneity among studies, subgroup analysis was performed. Better OS was associated with low PLR in Asian patients, patients with mixed type of operation performed, and patients with preoperative PLR ≤150. Low PLR was associated with significantly better DFS. <b><i>Conclusions:</i></b> PLR is a predictive factor of better DFS in patients with resectable pancreatic cancer. However, available evidence does not support PLR as a reliable prognostic factor for OS.
