Purpose To clarify the distribution of pathogenic bacteria by analyzing the bacterial susceptibility characteristics and risk factors for adult sepsis in The Wenzhou city, Zhejiang province, China, and to aid early diagnosis, monitoring, and prognosis prediction in cases of bacterial sepsis. Patients and Methods We retrospectively analyzed 329 patients with sepsis admitted to the Second Affiliated Hospital of Wenzhou Medical University between January 2018 and March 2021. Laboratory data were collected before and after treatment; moreover, the bacterial susceptibility characteristics and risk factors for sepsis were comprehensively analyzed using the Sequential Organ Failure Assessment (SOFA) score. Results The SOFA score was negatively correlated with the prognosis (P < 0.05). We isolated 47 pathogenic strains from blood culture samples, including 29 gram-positive strains, 18 gram-negative strains. The most common gram-negative pathogens in blood cultures are Klebsiella pneumoniae and Escherichia coli , while the most common gram-positive pathogens are Staphylococcus aureus and Staphylococcus h omini s . Gram-negative pathogens had resistance rates of 77% and 62.5% to ciprofloxacin and ceftriaxone, respectively. Gram-positive bacteria had a high resistance to penicillin at 100%. Prognostic factors for sepsis included patients’ consciousness, SOFA score, prothrombin time, international normalized ratio, fibrinogen, D-dimer, and aspartate aminotransferase (P < 0.05). Of these, the D-dimer level could predict the outcome of patients with sepsis (AUC = 0.661, P < 0.05). Conclusion The pathogens detected in adult sepsis in Wenzhou are mainly Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus , and Staphylococcus hominis . The pathogens exhibited differences in drug susceptibility. The optimal antibiotics should be chosen based on the principles of rational use and drug susceptibility. Combined with D-dimer levels, these parameters can be used to determine the optimal strategy for preventing and treating pathogenic bacteria.
Background: Tumor markers CEA, CYFRA21-1, NSE, proGRP, and SCC-Ag were routinely used for lung cancer. The objective of this study was to evaluate the diagnostic and prognostic value of these markers.Methods: The levels of 5 serum tumor markers were measured in 255 patients with lung cancer (44 squamous cell carcinoma, 183 adenocarcinoma, 28 small cell lung cancer), 103 patients with benign lung disease, and 120 healthy controls. The relevant clinical data of the patients were collected to analyze the expression of CEA, CYFRA21-1, NSE, proGRP, and SCC-Ag in the serum of lung cancer and their correlation with prognosis.Results: The positive rates and expression levels of CEA, CYFRA21-1, NSE, proGRP, and SCC-Ag in the lung cancer group were higher than those in patients with benign lung diseases and healthy controls. CYFRA21-1 and SCC-Ag were highly expressed in lung squamous cell carcinoma, and NSE and proGRP were highly expressed in small cell lung cancer. The expression levels of CYFRA 21-1, NSE, and proGRP in small cell lung cancer were higher than those in non-small cell lung cancer. The levels of CEA, CYFARA21-1, NSE, and proGRP were linearly correlated with the occurrence of lung cancer, while the level of SCC-Ag was not significantly correlated with the occurrence of lung cancer. What’s more, the levels of CYFAR21-1 and NSE in the death group of lung cancer patients were higher than those in the survival group.Conclusion: CEA, CYFRA21-1, NSE, proGRP, and SCC-Ag played a good role in diagnosing lung cancer. CYFRA21-1 and SCC-Ag can be used as markers for the diagnosis of squamous cell carcinoma, and NSE and proGRP can be used as markers for small cell lung cancer. Meanwhile, the combined detection of CEA, CYFARA21-1, NSE, and proGRP had the highest diagnostic accuracy for lung cancer. Furthermore, CYFAR21-1 and NSE can be used to evaluate the prognosis of lung cancer patients.
