A 60 years old lady, a diagnosed case of hypertension and hypothyroidism, admitted in CMH Dhaka with the complaints of high grade continuous fever, headache, vomiting and lower abdominal pain following total hysterectomy about two weeks back. On general and physical examination, she was found febrile, mildly anaemic, pitting oedema over both legs and erythematous skin rash over face, trunk and extremities. Relevant laboratory investigations were done including bone marrow aspiration which revealed haemophagocytic lymphohistiocytosis.

Background: Iron deficiency anaemia (IDA) is the most frequent form of anaemia in human population. For diagnosing IDA usually conventional laboratory tests such as serum iron, serum ferritin and transferrin saturation are used. However, both ferritin and transferrin proteins are markedly influenced by inflammation, behaving as acute-phase reactants and making it difficult to diagnosis iron-deficiency anemia (IDA) when it is combined with any inflammatory condition. Soluble transferrin receptor (sTfR) is a truncated extracellular form of the membrane transferrin receptor produced by proteolysis. Concentrations of serum sTfR are related to iron status and erythropoiesis in the body. Serum transferrin receptor (sTfR) levels are raised in iron deficiency but are not influenced by inflammatory changes. Aim: The aim of this study is to evaluate the significance of soluble transferrin receptors in diagnostic work up of iron deficiency. Materials and Methods: It was a prospective observational study carried out from June 2021 to November 2021 at the Department of Haematology and Biochemistry of Armed Forces Institute of Pathology (AFIP), Dhaka Cantonment. A total of 50 blood sample were collected and subjected to diagnose as microcytic hypochromic anaemia through complete blood count (CBC) and peripheral blood film (PBF). Then serum iron profile and serum sTfR was done by automated analyzer to evaluate differentials of microcytic hypochromic anaemia. Results: Among 50 cases 5 (10%) were male and 45 (90%) were female. Most of the patients were between 31-40 years age group (34%). Out of 50 patients 42 (84%) showed mild anaemia,6 (12%) showed moderately anaemia and 2(4%) showed severely anaemia according to reference range. Then serum iron profile was done. Among 50 samples 37 (74 %) had low serum iron, 18 (36 %) had high TIBC and 45 (90%) had low serum ferritin in comparison with reference range. Also this study revealed high serum sTfR than normal in 48 (96%) patients. While evaluating the frequency of sTfR level in perspective of both male and female anaemic patients, p-value was found < 0.0001 which was statistically significant. Conclusion: This study demonstrates that sTfR level in conjunction with other biochemical markers of iron deficiency anaemia is very useful in evaluating iron status. Serum sTfR is a new diagnostic tool for evaluating of iron deficiency anemia when it is associated with other inflammatory condition.
Background: There have been a wide variety of clinical publications on coronavirus disease 19 (COVID-19) focused on specific biomarkers. Acute-phase reactants, such as C-reactive protein (CRP), ferritin, serum amyloid A (SAA), and procalcitonin, have been identified as sensitive markers of acute COVID-19 illness, even though they are nonspecific markers. Objective: The purpose of this study is to summarize the role of several biomarkers in the stratification of COVID-19 disease severity. Methods: This study followed systematic literature review method. The systematic review followed the review process as it was well developed and planned to reduce biases and eliminate irrelevant and low-quality studies. The steps for implementing a systematic review include correctly formulating the COVID-19 question to answer, developing a protocol based on inclusion and exclusion criteria, performing a detailed and broad literature search and screening the abstracts of the studies identified in the search and subsequently of the selected complete texts. After selecting the study, the next steps were synthesis of the evidence like extract the necessary data into a form designed in the protocol to summarise the included studies, assess the biases of each study, identifying the quality of the available evidence, and develop tables and text that synthesise the evidence. The secondary sources of data for this study included different published topics from national & international journals. Good number of Journal articles was taken regarding “Role of Biomarkers in the Stratification of COVID-19”. Published articles were collected from renowned indexing data source like PubMed, Medline, and Scopus. Etc. Conclusion: Significantly increased white blood cell count, lymphopenia, decreased CD3, CD4, or CD8 T-lymphocyte counts, high neutrophil count, thrombocytopenia, and dramatically elevated inflammatory biomarkers were all linked to severe disease and the probability of developing sepsis as the disease progressed. Progressive decreases with lymphopenia, thrombocytopenia, elevated CRP, procalcitonin, increased liver enzymes, impaired renal function, and coagulation derangements were more common in critically sick patients and were linked to a higher rate of clinical sequelae. In seriously and critically ill patients, elevated interleukin levels and significantly increased SAA were most frequently reported. The neutrophil to lymphocyte ratio, the systemic immune inflammation index, and the COVID-19 Severity Score are all indicators of systemic inflammation that can be used to predict disease severity, outcome, and death.
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.
