Introduction:Human coronavirus disease 2019 (COVID-19) is an emerging respiratory disease that has become pandemic worldwide. The patients have a range of mild to severe symptoms, such as pneumonia, acute respiratory distress syndrome, arrhythmia, shock, and other organs involvement. Clinical and hematological evidence can serve as a prognostic factor to detect severe cases of COVID-19. Objectives: The present study aimed to evaluate hematological parameters related to the severity of the disease in COVID-19 patients in Mashhad, Eastern Iran. Patients and Methods: All the individuals with positive real-time reverse transcription-polymerase chain reaction test results and the patients with clinical symptoms whose computed tomography scan results were matched with the diagnosis of viral pneumonia were included in the study. The hematological examinations and complete blood count of the patients were performed by the healthcare personnel through collecting blood samples at the time of admission and discharge from the hospital. Results: In total, 189 COVID-19 patients were included in the study, 47.6% and 58.73% of whom were over 60 years old and male, respectively. Investigation of the hematological parameters revealed that the number of white blood cells, mean value of corpuscular volume, number of platelets, and lymph count had significantly increased at the time of discharge (P<0.01). On the other hand, red blood cells, hemoglobin, hematocrit, mean corpuscular hemoglobin, mean corpuscular hemoglobin, and red cell distribution width values were significantly higher at the time of admission in comparison to discharge (P<0.01). Furthermore, it was found that male gender had a significant relationship with the development of lymphopenia in the patients (P=0.021). Conclusion: It can be concluded that hematological parameters and inflammatory biomarkers in COVID-19 patients could potentially act as the independent factors and affect the prognosis of the disease.
TAFRO syndrome is a new presentation of idiopathic multicentric Castleman disease which is termed as thrombocytopenia, anasarca, myelofibrosis, renal failure and organomegaly (TAFRO). The exact pathophysiology of TAFRO syndrome is unclear and management is mostly based on case reports and expert opinion. In this report, a 37 years old male patient with TAFRO syndrome is discussed. The patient was referred with fever, sweating, anorexia, abdominal distension and generalized edema which has been hospitalized multiple times for such complaints. The patient also developed skin lesions dispersed in red nodules, which was reported as "granuloid hemangioma". Renal biopsy suggested mesangioproliferative glomerulonephritis and bone marrow specimen showed hypercellular active marrow with reticulin fibrosis. The lymph node biopsies were reported as Castleman disease. This report demonstrates that different manifestations of TAFRO syndrome may overlap with other syndromes and can be managed by Bortezomib and Tocilizumab.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
