RESUMO
This prospective, observational, cross-sectional study was undertaken to estimate the burden of anaemia in malaria and to evaluate the contribution of haematogenic factors and haemolysis in its pathogenesis. Haematogenic factors (vitamin B12, folic acid, lactate dehydrogenase, ferritin, total iron binding capacity, direct Coombs test) were estimated in patients with malaria at the time of admission. They were categorized as anaemics or non-anaemics and their complications and outcomes were recorded. P. vivax (97/112) and P. falciparum (13/112) mono-infections dominated; anaemia was seen in 63.3%. Patients with and without anaemia were comparable in terms of haemolysis and the haematogenic factors evaluated. Bleeding events, acute kidney injury and acute liver injury were comparable; however, the need for mechanical ventilation and transfusion of blood products was significantly higher amongst the anaemics. We concluded that haemolysis and presumably transient bone marrow suppression contribute to anaemia in malaria. Pre-existing nutritional deficiencies do not, however, predispose to severe malaria.

BACKGROUND: National Hemovigilance Programme aims at improving patient and donor outcomes by monitoring adverse reactions. This requires an additional effort by existing manpower that is already a handful and may offer a leeway if not mandated and designated to a hemovigilance nurse. AIMS AND OBJECTIVES: To analyse the reported adverse transfusion reactions (ATR) and their subsequent uplink/upload into the Hemovigilance program of India (HvPI) and to observe subjective discrepancy in the diagnosis of ATR and their imputability to transfusion. MATERIAL AND METHODS: ATR were analysed from May 2016 to October 2021 in a hospital-based blood centre in India. Two groups were formed, Group I constituted ATR that were reported and uplinked to HvPI, and Group II constituted all reported ATR irrespective of the uplink/upload. All ATR were reanalysed for a subjective discrepancy in diagnosis and imputability levels. Results were analysed online statistical software MedCalc using the "Exact Poissons Method" and the Chi-square test with a significant p-value of <0.05. RESULTS: In total 169 ATR were reported in 166 patients and 89 (52.6%) were uplinked, with an incident rate of 1 in 1412 and 1 in 743 in Group I and Group II respectively. The difference was statistically significant (p < 0.0001). Allergic reactions were the most common type in both groups followed by FNHTR with PRBC as the most implicated blood product. A discrepancy of around 4.3% and 17.9% in diagnosis and imputability level respectively was observed. CONCLUSIONS: The difference in incidence rates in the two groups indicates a mandate for dedicated hemovigilance nurses in every centre to aid in accurate data sharing with the National hemovigilance systems. Discrepancies in diagnosis can be mitigated by identification and understanding of ATR through case-based objective approach. Discrepancy in assigning imputability levels to adverse reactions can be minimised by objectifying the scales followed by spreading awareness though campaigns. These initiatives can effectively be aided by the hemovigilance nurse.

Objective PD-L1, a 40 kDa type 1 transmembrane protein, suppresses the adaptive arm of the immune system. The interaction of PD-1 with the ligand PD-L1 inhibits cytokine production and plays a role in the progression of lung cancer. The present study was performed to observe the expression of PD-L1 in lung carcinoma patients and its correlation with histopathological grade, stage, and survival of patients. Materials and Methods This prospective study included all new cases of lung carcinoma diagnosed on histopathological or cytopathological examination over a period of 1 year. PD-L1 immunoexpression was statistically analyzed and graded according to the Tumor Proportion Score in all cases and correlated with histopathological grade, stage, and survival of patients. Results This study included 56 cases of lung carcinoma with 64.2% cases showing PD-L1 positivity, out of which 44.6% were non-small cell and 19.6% were small cell lung carcinoma. In all, 32.1% cases with lymphovascular invasion, 53.5% with necrosis, and 37.5% cases with greater than 5/10 HPF mitotic figures showed positive PD-L1 expression. Paired cell blocks and histopathology showed 70% concordance for PD-L1 expression. 16.1% cT3N1M0 cases and 25% stage IIIA cases showed PD-L1 positivity. In all, 60.7% patients with positive PD-L1 expression did not survive for 12 months following diagnosis. Conclusion PD-L1 immunoexpression was increased in lung carcinoma cases and was associated with poor histomorphological features including lymphovascular invasion, necrosis, and increased mitotic activity. PD-L1 correlated with cases having decreased 12-month survival and stage IIIA carcinoma. Thus, it may be useful in the stratification of patients who benefit from the PD-L1 targeted therapy.
RESUMO
The liver keeps haematological parameters normal and preserves haemostasis by storing iron, vitamin B-12, and, folic acid, necessary for healthy haematopoiesis. Anaemia of various aetiologies affects approximately 75% of chronic liver disease (CLD) patients, specifically caused by iron deficiency, hypersplenism, chronic diseases, autoimmune haemolysis, folic acid deficiency, aplasticity, and as a side effect of antiviral drugs. This study sought to observe the derangements in haematological parameters in patients with CLD, analyse the spectrum of anaemia in patients with CLD, and predict CLD outcomes utilizing Child-Pugh Score. This cross-sectional observational research was carried out in the Department of General Medicine, Himalayan Institute of Medical Sciences (HIMS), Dehradun, India over the course of a year. The patients with CLD who were admitted to the ward participated in the study. Most patient's blood pictures reported normocytic normochromic with thrombocytopenia (TCP) (28.7%), macrocytic hypochromic with TCP (26%), microcytic hypochromic with TCP (13.3%) and macrocytic normochromic with TCP (9.3%). The incidence of anaemia was 85.3%: mild in 12.7% patients, moderate in 55.3% patients, and severe in 17.3% patients. Interestingly, this study also builds upon others suggesting that 85.9% of CLD patients have Class C Child-Pugh Score.
RESUMO
Pure red cell aplasia (PRCA) is characterized by severe anemia with reticulocytopenia and bone marrow erythroblastopenia. The early erythroblasts are markedly decreased; however, in rare instances, they may be normal or raised in number. There are varied etiologies, namely congenital or acquired and primary or secondary. The congenital PRCA is known as "Diamond-Blackfan anemia." Thymomas, autoimmune disease, lymphomas, infections, and drugs also may be familiar associates. However, the etiologies of PRCA are numerous, and many diseases/infections can be associated with PRCA. The diagnosis rests on clinical suspicion and appropriate laboratory workup. We evaluated nine cases of red cell aplasia, having severe anemia with reticulocytopenia. Nearly half of the cases showed adequate erythroid (> 5% of the differential count) but with a maturation arrest. The adequacy of the erythroid could confuse the hematologist and may even delay the diagnosis. Hence, it is empirical that PRCA could be considered a differential in every case of severe anemia with reticulocytopenia, even in the presence of adequate erythroid precursors in the bone marrow.
RESUMO
BACKGROUND: High-dose vitamin E intake is known to inhibit vitamin K-derived coagulation factor synthesis, which can cause serious bleeding events such as gastrointestinal bleeding and intracranial hemorrhage. We report a case of coagulopathy induced by marginally increased levels of vitamin E. CASE PRESENTATION: A 31-year-old Indian man presented with oral bleeding, black tarry stools, and bruising over his back. He had been taking non-steroidal anti-inflammatory drugs for low backache and vitamin E for hair loss. He had mild anemia with normal platelet count, thrombin time, and prolonged bleeding time, activated partial thromboplastin time, and prothrombin time. Serum fibrinogen was slightly raised. Mixing studies with pooled normal plasma, aged plasma, and adsorbed plasma were suggestive of deficiency of multiple coagulation factors due to acquired vitamin K deficiency. Serum phylloquinone was normal, while prothrombin induced by vitamin K absence-II level was increased. Serum alpha-tocopherol was slightly raised. Upper gastrointestinal endoscopy showed multiple gastroduodenal erosions. A final diagnosis of vitamin E toxicity-related coagulopathy was made. The patient responded well to pantoprazole, vitamin K supplementation, multiple fresh frozen plasma transfusions, and other supportive treatments besides the discontinuation of vitamin E supplementation. The coagulation parameters normalized, and the patient was discharged with complete resolution of symptoms and remained asymptomatic during the follow-up for 6 months. CONCLUSIONS: Vitamin E-related inhibition of vitamin K-dependent factors with coagulopathy may occur even at marginally increased levels of serum vitamin E. This risk becomes significant in patients receiving other drugs that may increase the risk of bleeding.

INTRODUCTION: Studies have documented the role of the "neutrophil-to-lymphocyte ratio" (NLR) in influenza virus infection. In addition, morphometric parameters derived from automated analyzers on the volume, scatter and conductivity of monocytes, neutrophils and lymphocytes in many viral etiologies have helped with their early differentiation. With this background, we aimed to characterize the hematological changes of coronavirus-positive cases and also compare them with the healthy controls and patients affected by non-COVID Influenza-like illnesses so that early isolation could be considered. MATERIAL AND METHODS: This was a cross-sectional analytical study carried out in the years 2020-2022. All cases with COVID-19 and non-COVID-19 Influenza-like illnesses and healthy controls above 18 years were included. Cases were diagnosed according to the WHO guidelines. All samples were processed on a Unicel DxH 800 (Beckman Coulter, California, USA) automated hematology analyzer. The demographic, clinical and regular hematological parameters along with additional parameters such as volume, conductivity and scatter (VCS) of the three groups were compared. RESULTS: The 169 COVID-19 cases were in the moderate to severe category. Compared with 140 healthy controls, the majority of the routine hematological values including the NLR (neutrophil-to-lymphocyte ratio) and PLR (platelet-to-lymphocyte ratio) showed statistically significant differences. A cutoff of an absolute neutrophil count of 4350 cell/cumm was found to have a sensitivity of 76% and specificity of 70% in differentiating moderate and severe COVID-19 cases from healthy controls. COVID-19 and the non-COVID-19 Influenza-like illnesses were similar statistically in all parameters except the PLR, mean neutrophilic and monocytic volume, scatter parameters in neutrophils, axial light loss in monocytes and NLR. Interestingly, there was a trend of higher mean volumes and scatter in neutrophils and monocytes in COVID-19 cases as compared to non-COVID-19 Influenza-like illnesses. CONCLUSION: We demonstrated morphological changes in neutrophils, monocytes and lymphocytes in COVID-19 infection and also non-COVID-19 Influenza-like illnesses with the help of VCS parameters. A cutoff for the absolute neutrophils count was able to differentiate COVID-19 infection requiring hospitalization from healthy controls and eosinopenia was a characteristic finding in cases with COVID-19 infection.

The understanding of coronavirus disease 2019 (COVID-19) is evolving periodically. There is also a marked increase in COVID-19 patients' demand for the provision of COVID-19 convalescent plasma (CCP) therapy. With the review of the literature, the stage of speculation is quickly moving towards conformity, with the interim guidelines given by the Food and Drug Administration (FDA) in the United States, United Kingdom's blood transfusion services, Saudi's FDA, and the Indian Council for Medical Research, in addition to the European health authorities. It is prudent to address the ethical concerns that merit consideration while harvesting and utilizing CCP as a therapeutic tool in local hospital setting.
RESUMO
Blood clots in the packed red blood cell [PRBC] unit can sometimes go unrecognized and could eventually give rise to flow problems while administering the same. We herein report our observation of a moderately elongated threadlike clot in a PRBC unit prepared from a whole blood donated by a young Indian male donor. The PRBC unit was returned to us from the ward by the nursing staff citing "flow issues". In fact, this warranted the initiation of root-cause analysis of the entire event led by two faculty members, one post-graduate student and the technical supervisor at our blood centre.

Intake of a fatty meal before donating blood can lead to an increased level of plasma triglyceride concentration for several hours. This may cause either turbid and or "milky-white" appearance of their venous plasma samples. We, however, report a peculiar case about a male blood donor from India, whose plasma appeared to be "strawberry milky-white" in colour. On inquiry, he gave a history of poorly controlled diabetes mellitus type-II. Further, this was affirmed by his high blood glucose concentration [nearly 326mg/dL] and HbA1c [13.7%] respectively. Moreover, his plasma triglyceride concentration was elevated up to 376mg/dL. His treatment was started at our hospital and the strawberry colour of his plasma, dramatically recovered to normal straw-colour after achieving a fairly good glycemic control with the insulin therapy.

The only effective way to provide individuals with herd immunity against the novel coronavirus [SARS-CoV-2] is to administer an effective vaccine that will help check the current pandemic status. In India, the central drugs standard control organization (CDSCO) has granted the emergency-use authorization [EUA] to three vaccines namely, Covishield (live vaccine, Oxford AstraZeneca, United Kingdom being manufactured by the Serum Institute of India), Covaxin (inactivated vaccine, Bharat Biotech, India) and Sputnik V (live vaccine, Gamaleya, Russia). However, there is a rising need for the efficacy of the vaccines to be proven against the "SARS-CoV-2 viral variants." Also, human plasma is polyclonal in nature with an inherent propensity to identify multiple epitopes of either an antigen or pathogen. With this context in mind, the researchers hypothesize that using COVID-19 convalescent plasma [CCP] harvested from the locally recovered individuals [i.e. potential CCP donors] may be particularly beneficial in combating not only the founder SARS-CoV-2 virus but also the geographically determined SARS-CoV-2 variants among the regionally affected COVID-19 patients.

Solitary benign fibrous mesothelioma (BFM) is uncommon and is termed as solitary fibrous mesothelioma or localized fibrous mesothelioma. Although the most common site for its development is the pleural region (65%), it has also been reported in the peritoneum. They are mostly seen in adults (average age: 54 years). Herein, we present a case of BFM in a 2-year-old male child, who presented to our hospital with abdominal pain and a lump in the abdomen. Differential diagnosis included solitary fibrous tumor, gastrointestinal stromal tumor, and benign fibrous lesions of mesentery. Establishing a preoperative diagnosis is difficult on the basis of clinical parameters or imaging studies and final diagnosis can only be assessed based on the results of histopathological and immunohistochemical examination.
