Mannose-binding lectin (MBL) is one of the important parts of the complement system. In our study, we aimed to determine serum MBL levels and their relationship with intensive care hospitalization. Ninety COVID-19-positive patients from outpatient clinics and clinics were included in this study. The patients were evaluated in three groups as mild, moderate, and severe groups. Each group consisted of 30 patients. A venous blood sample was taken once from each patient. Serum MBL, C-reactive protein (CRP), lactate dehydrogenase (LDH), fibrinogen, D-dimer, and ferritin levels were measured. The mean serum MBL levels of all patients were 695.46±324.42 ng/mL. One-way ANOVA test resulted in significant differences in serum CRP, LDH, fibrinogen, D-dimer, ferritin, and MBL levels between groups (p<0.05 for all comparisons). Post-hoc Tukey analysis showed significant differences in serum MBL levels between mild and severe groups and moderate and severe groups. MBL may be used as a prognostic biomarker in COVID-19 patients. Further studies are needed to determine MBL in treatment strategies.

UI MeSH Term Description Entries
D002097 C-Reactive Protein A plasma protein that circulates in increased amounts during inflammation and after tissue damage. C-Reactive Protein measured by more sensitive methods often for coronary heart disease risk assessment is referred to as High Sensitivity C-Reactive Protein (hs-CRP).

D000086382 COVID-19 A viral disorder generally characterized by high FEVER; COUGH; DYSPNEA; CHILLS; PERSISTENT TREMOR; MUSCLE PAIN; HEADACHE; SORE THROAT; a new loss of taste and/or smell (see AGEUSIA and ANOSMIA) and other symptoms of a VIRAL PNEUMONIA. In severe cases, a myriad of coagulopathy associated symptoms often correlating with COVID-19 severity is seen (e.g., BLOOD COAGULATION; THROMBOSIS; ACUTE RESPIRATORY DISTRESS SYNDROME; SEIZURES; HEART ATTACK; STROKE; multiple CEREBRAL INFARCTIONS; KIDNEY FAILURE; catastrophic ANTIPHOSPHOLIPID ANTIBODY SYNDROME and/or DISSEMINATED INTRAVASCULAR COAGULATION). In younger patients, rare inflammatory syndromes are sometimes associated with COVID-19 (e.g., atypical KAWASAKI SYNDROME; TOXIC SHOCK SYNDROME; pediatric multisystem inflammatory disease; and CYTOKINE STORM SYNDROME). A coronavirus, SARS-CoV-2, in the genus BETACORONAVIRUS is the causative agent. 2019 Novel Coronavirus Disease,2019 Novel Coronavirus Infection,2019-nCoV Disease,2019-nCoV Infection,COVID-19 Pandemic,COVID-19 Pandemics,COVID-19 Virus Disease,COVID-19 Virus Infection,Coronavirus Disease 2019,Coronavirus Disease-19,SARS Coronavirus 2 Infection,SARS-CoV-2 Infection,Severe Acute Respiratory Syndrome Coronavirus 2 Infection,COVID19,2019 nCoV Disease,2019 nCoV Infection,2019-nCoV Diseases,2019-nCoV Infections,COVID 19,COVID 19 Pandemic,COVID 19 Virus Disease,COVID 19 Virus Infection,COVID-19 Virus Diseases,COVID-19 Virus Infections,Coronavirus Disease 19,Disease 2019, Coronavirus,Disease, 2019-nCoV,Disease, COVID-19 Virus,Infection, 2019-nCoV,Infection, COVID-19 Virus,Infection, SARS-CoV-2,Pandemic, COVID-19,SARS CoV 2 Infection,SARS-CoV-2 Infections,Virus Disease, COVID-19,Virus Infection, COVID-19
