Background: We evaluated whether the serum procalcitonin (PCT) level could predict death in severe and critical coronavirus disease 2019 (COVID-19) patients.Methods: This study included 129 COVID-19 patients. PCT levels on admission, treatment, and death were collected. The outcomes were compared.Results: The optimum cutoff value of the PCT level determined by receiver operator characteristic curve analysis to predict all-cause death was 0.085 ng/mL, with sensitivity of 95.7% and specificity of 72.6%. Overall, 78 patients had a PCT level below 0.085 ng/mL and 51 patients had a PCT level of 0.085 ng/mL or greater. High-PCT-level patients had lower levels of lymphocytes (P=0.001) and albumin (P=0.002) and higher levels of creatinine (P=0.024), D-dimer (P=0.002), and white blood cells, neutrocytes (P<0.001), high-sensitivity C-reactive protein (P<0.001), interleukin-6 (P<0.001), interleukin-8 (P=0.001), interleukin-10 (P=0.001), tumor necrosis factor (P<0.001), erythrocyte sedimentation rate (P=0.001), and ferritin (P=0.001). During the 30-day observation period, 23 patients died. Mortality was significantly higher in high-PCT-level patients than in patients with low PCT levels (43.1% vs. 1.3%; P<0.001). The risks of death (P<0.0001) and ventilator use (P<0.0001) were increased in patients with PCT levels of 0.085 ng/mL or greater.Conclusions: A PCT level of 0.085 ng/mL or greater on admission could effectively predict death and ventilator use in severe and critical COVID-19 patients.

Objective To investigate the association between serum angiopoietin-like 4 (ANGPTL4) levels and recurrence of atrial fibrillation (AF) after catheter ablation. Methods This retrospective study recruited patients with AF undergoing catheter ablation and they were divided into two groups (new-onset AF group and recurrent AF group). Demographic, clinical, and laboratory parameters were collected. Results A total of 192 patients with AF were included, including 69 patients with recurrence of AF. Serum ANGPTL4 levels were lower in patients with recurrent AF than in those with new-onset AF. Serum ANGPTL4 levels were positively correlated with superoxide dismutase and peroxisome proliferator-activated receptor γ, and negatively correlated with the CHA2DS2-VASC score, left atrial diameter, and levels of brain natriuretic peptide, malondialdehyde, high-sensitivity C-reactive protein, and interleukin-6. The receiver operating characteristic curve showed that the best cut-off for recurrent AF was serum ANGPTL4 levels  < 19.735 ng/mL, with a sensitivity and specificity of 63.9% and 74.5%, respectively. Serum ANGPTL4 levels were significantly associated with recurrence and new onset of AF (odds ratio, 2.241; 95% confidence interval, 1.081–4.648). Conclusions Serum ANGPTL4 levels are lower in patients with recurrent AF than in those with new-onset AF, and are associated with cardiac hypertrophy, oxidative stress, and inflammation.

Abstract Background Hematology analyzers display abnormal parameters during malaria infection providing insightful information for suspecting and assessing malaria infection. The goal of this study is to demonstrate the potential of a three-part differential hematology analyzer to assess malaria, provide information about the parasitemia, and discuss the importance of combining C-reactive protein (CRP) with hematology parameters to obtain further information about the malaria infection. Methods The present study shows the results of a case–control study during the monsoon season of years 2018 and 2019 in Mumbai, India. The study considers 1008 non-malaria febrile cases, 209 P. vivax and 31 P. falciparum positive malaria samples, five cases of mixed P. vivax and P. falciparum infection, and three co-infection cases of P. vivax and dengue. Raw data from the three-part analyzer LC-667G CRP (HORIBA) and the corresponding microscopic findings (golden standard for diagnosis of malaria) were obtained for each sample. Results The medians of platelet counts (PLT) were 102.5, 109.0, and 223.0 × 103/µL, while CRP medians were 67.4, 81.4 and 10.4 mg/L in P. vivax, P. falciparum and control groups respectively (p < 0.001 in Mann–Whitney U tests between malaria and control groups). Compared with negative samples, platelets counting less than 161.5 × 103/µL were observed on malaria patients (OR 19.12, 95% CI 11.89–30.75). Especially in P. vivax cases, an abnormal peak was frequently observed in the white blood cells (WBC) histogram around the 37fL channel. The events counted around that channel showed a linear correlation with the counting of red blood cells infected predominantly with larger parasitic forms. Parameters like CRP (rs = 0.325, p < 0.001), WBC (rs = 0.285, p < 0.001) and PLT (rs = − 0.303, p < 0.001) were correlated with the parasitemia of P. vivax samples. Between the malaria and dengue groups, the highest area under the receiver operating characteristic curve was observed on CRP (0.867, CRP ≥ 26.85 mg/L). Conclusions A three-part differential hematology analyzer has the potential to not only trigger malaria diagnosis confirmation but also assess the severity of the infection when CRP is considered.

Aim. To estimate clinical and laboratory parameters in patients with osteoarthritis (OA) and in those with OA and metabolic syndrome (MS). Subjects and methods. 164 patients with OA were examined and divided into 2 groups of 82 people: a study group (patients with MS) and a control one (those without MS). OA was defined according to the diagnostic criteria described by R.D. Althmann (1995). MS was identified based on the criteria developed by the International Diabetes Federation (2005). The location of affected and swollen joints was determined according to the Richie index; the intensity of pain syndrome was measured by a visual analogue scale at rest and on movement; the WOMAC and Lequesne indexes were estimated in the patients. Erythrocyte sedimentation rate and C-reactive protein and tumor necrosis factor-α levels were determined from laboratory data. Results. In the MS group, the frequency of joint injuries at various sites, the prevalence of synovitis, and the intensity of pain and inflammation were significantly higher than in the non-MS group. Conclusion. The negative impact of MS on the clinical picture of OA can be inferred by the findings.
