ABSTRACT
Introduction: Coronavirus disease 2019 (COVID-19) triggers the immune system and causes changes in the serum level of inflammatory markers such as erythrocyte sedimentation rate (ESR), C-reactive protein, ferritin, interleukin-6, LDH, D-dimer, and procalcitonin (PCT); in this study, we investigate the association between the serum level of inflammatory markers and the prognosis of COVID-19, which included mortality and intensive care unit (ICU) admission of patients. Methods: This cross-sectional study was conducted on 200 COVID-19 patients hospitalized at Ayatollah Rouhani Hospital, Babol, from March 2020 to March 2021. Demographic indicators and inflammatory markers were recorded in the questionnaire and were investigated based on disease outcome, length of hospitalization, need for non-invasive ventilation (NIV), and need for hospitalization in the ICU and ventilator. Patients who died or were discharged within the first 24 hours of hospitalization (before the test) were excluded from the study. Finally, the data were recorded in SPSS Statistics 26.0 and then analyzed. Results: The average age of patients with COVID-19 hospitalized in the hospital was 57.92 ± 16.18. The prevalence of death due to coronavirus disease in hospitalized patients was 8.5%. Besides, 23.5% of patients were hospitalized in the ICU and 28.5% required NIV. Based on the disease's outcome, a significant difference was found in the neutrophil-to-lymphocyte ratio (NLR), so the NLR was significantly higher in patients who died due to coronavirus. Moreover, the levels of erythrocyte sedimentation rate (ESR), D-dimer, LDH, and PCT in deceased individuals were considerably higher compared to those who recovered. Conclusion: NLR, ESR, D-dimer level, LDH, and PCT are among the markers that affect COVID-19 patient outcomes. The increment of any of these markers will lead to an increase in the risk of death and also the need for ICU admission.
ABSTRACT
Cancer treatment is presently one of the most important challenges in medical science. Surgery, chemotherapy, radiotherapy, or combining these methods is used to eliminate the tumor. Hormone therapy, bone marrow transplantation, stem cell therapy as well as immunotherapy are other well-known therapeutic modalities. Immunotherapy, as the most important complementary method, uses the immune system for treating cancer followed by surgery, chemotherapy, and radiotherapy. This method is systematically used to prevent malignancies development mainly via potentiating antitumor immune cells activation and conversely compromising their exhaustion with the lowest negative effects on healthy cells. Active immunotherapy can be employed for cancer immunotherapy by directly using the ingredients of the immune system and activating immune responses. On the other hand, inactive immunotherapy is utilized by indirect induction and using immune cell-based products consisting of monoclonal antibodies. It has strongly been proved that combination therapy with immunotherapies and other therapeutic means, such as anti-angiogenic agents, could be a rational plan to treat cancer. Herein, we have focused on recent findings concerning the therapeutic merits of cancer therapy using immune checkpoint inhibitors (ICIs), adoptive cell transfer (ACT) and cancer vaccine alone or in combination with other approaches. Also, we offer a glimpse into the current challenges in this context.
