Efficiencies of Laboratory Parameters in Covid-19 Patients Follow up: Turkish Journal of Medical and Surgical Intensive Care Medicine

Introduction: Diagnostic efficiencies of laboratory parameters used in COVID-19 patients and their association with disease severity were evaluated. Materials and Methods: Laboratory parameters of COVID-19 patients hospitalized in Dr. Lütfi Kırdar Kartal City Hospital between March and August 2020 were evaluated. The patients were grouped as non-severe and severe according to the interim guidance of the World Health Organization (WHO). The diagnostic performances of NLR, D-dimer, CRP, procalcitonin, IL-6, LDH, and ferritin in discrimination of severe cases were evaluated by Receiver operator’s characteristics (ROC) analysis. Generalized lineer model Analysis (GLM) was performed with mortality as a dependent variable and age, gender, NLR, D-dimer, CRP, Procalcitonin, IL-6, LDH, and ferritin as an independent variables. Results: A total of 257 patients were evaluated and there was a significant difference between non-severe and severe cases in terms of NLR, D-dimer, CRP, Procalcitonin, IL-6, LDH, and Ferritin values. All the parameters showed comparable performances in discriminating severe disease;D-dimer with the least (AUC 73.5%), and NLR with the highest (AUC 80.7%) efficiency. Values above 4.5 for NLR, 930 ug/L for D-dimer, 64 mg/L for CRP, 0.136 ug/L for procalcitonin, 44.3 pg/mL for IL-6, 304 IU for LDH, and 312 ug/L for ferritin were associated with severe disease. Contribution of age, NLR, D-dimer, and CRP were found significant on the model. Conclusions: NLR, D-dimer, CRP, procalcitonin, IL-6, LDH, and ferritin showed comparable performances in discriminating severe cases with predefined cut-offs. Age, NLR, D-dimer, and CRP may be considered as predictors of mortality in COVID-19 patients.

Antibody responses to the SARS-CoV-2 vaccines in hemodialysis patients: Is inactivated vaccine effective?

INTRODUCTION: Vaccines generally have reduced effectiveness in hemodialysis patients and a similar condition may also apply for the SARS-CoV-2 vaccines. The aim of this study was to analyze humoral responses of hemodialysis patients to SARS-CoV-2 vaccines. METHODS: Eighty-five maintenance hemodialysis patients who received either inactivated or mRNA SARS-CoV-2 vaccines were investigated. Antibody levels were measured by a commercial antibody kit, which detected antibodies toward receptor binding domain of the SARS-CoV-2 spike protein. Comparative analyzes were carried between vaccine groups and with a control group of 103 healthy volunteers. RESULTS: Seropositivity rate and antibody levels were significantly lower in hemodialysis patients who received inactivated vaccine (p = 0.000). While mRNA vaccine had better immunogenicity, both vaccines protected from symptomatic infection when seropositivity was achieved. DISCUSSION/CONCLUSION: When used in the same dose with the general population, inactivated SARS-CoV-2 vaccines generate reduced humoral response in hemodialysis patients. mRNA vaccines have better immunogenicity in this group.

Percutaneous cholecystostomy instead of laparoscopy to treat acute cholecystitis during the COVID-19 pandemic period: single center experience.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the accepted standard treatment for acute cholecystitis (AC) in patients eligible for surgery. Percutaneous cholecystostomy (PC) can provide a permanent treatment for high-risk patients for surgery or act as a bridge for later surgical treatment. This study is an evaluation of the use of PC during the current coronavirus 2019 (COVID-19) pandemic at a single hospital. METHODS: Fifty patients with AC were admitted as of the start of the COVID-19 pandemic in Turkey through June 2020. Patients with pancreatitis, cholangitis, and/or incomplete data were excluded from the study. Data of the remaining 36 patients included in the study were recorded and a descriptive statistical analysis was performed. The patients were divided into three groups: PC (n=14), only conservative treatment with antibiotherapy (OC) (n=14), and LC (n=8). The findings were compared with a group of 70 similar patients from the pre-pandemic period. RESULTS: The mean age of the pandemic period patients was 53 years (range: 26-78 years). The female/male ratio was 1.11. PC was preferred in eight (11%) patients in the same period of the previous year, whereas 14 (39%) patients underwent PC in the pandemic period. Four of the 36 pandemic patients were positive for COVID-19, including one member of the PC group. There was one (7.1%) mortality in the pandemic-period PC group due to cardiac arrest. The length of hospital stay between the groups based on the type of treatment was not statistically significant. CONCLUSION: LC is not recommended during the pandemic period; PC can be an effective and safe alternative for the treatment of AC.
