Nucleic Acid Amplification Testing for Human Immunodeficiency Virus, Hepatitis B Virus, and Hepatitis C Virus in Blood Donors at a Tertiary Care Hospital Blood Bank.

Objective The objective was to assess the efficacy of nucleic acid amplification testing (NAAT) in conjunction with serology for detecting hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) in donor blood products. Methodology This retrospective cross-sectional study aimed to evaluate the use of NAAT and viral serology in screening donor blood products for HBV, HCV, and HIV. The study was conducted at the Dr Ishrat-ul-Ebad Khan Khan Institute of Blood Diseases at Dow University of Health Sciences in Karachi, Pakistan, from April 2018 to May 2022.

A clinical audit on the utilization of group O-negative red cells and the lesson learnt.

Background: Ideal blood inventory management involves guaranteeing maximal availability of blood while minimizing wastage. Benchmark for the guidance of O (Rh) D-negative red blood cells (ONEG RBCs) is not widely available. In this study, we aimed to identify the areas of improvement in blood center inventory of ONEG RBCs through a clinical audit.

A Bizarre Progression Of Chronic Lymphocytic Leukaemia Into Diffuse Large B-Cell Lymphoma.

A 65-year-old male presented with complaints of weakness, lethargy, abdominal pain, and low-grade fever for the last few months. His examination revealed generalized lymphadenopathy and splenomegaly. A subsequent laboratory workup revealed atypical lymphoid cells with prominent double-bright positivity of CD19 and CD5 markers.

Bombay Blood Group Phenotype Misdiagnosed As O Phenotype: A Case Report.

Bombay blood group is a rare type that was initially identified in the city of Bombay, India. It is characterized by the presence of serum antibodies anti-A, anti-B, and anti-H, which can cause agglutination in all blood groups within the ABO system. The clinical importance of the Bombay blood group lies in its inability to receive transfusions from other blood groups.

Disseminated Fungal Infection On Bone Marrow Trephine In An Asplenic Patient.

hyposplenism increases the risk of life-threatening infection with encapsulated bacteria. however, literature review revealed that hyposplenism is also a risk factor for disseminated fungal infection. here, we report a case of individual who presented with pyrexia of unknown origin and had splenectomy for hemolytic anemia and later he found to have disseminated fungal infection on bone marrow examination.

Niemann-Pick Disease on Bone Marrow Trephine: A Rare Manifestation.

Niemann-Pick disease has an autosomal recessive inheritance pattern and occurs due to a deficiency of a lysosomal enzyme, sphingomyelinase. It causes variable clinical signs and symptoms such as hepatosplenomegaly, delayed milestones, and peripheral cytopenia due to bone marrow involvement. Here, we report a case of a child who presented with hepatosplenomegaly and pancytopenia, who was later found to have Niemann-Pick disease on bone marrow examination.

Seroprevalence of Hepatitis B, Hepatitis C, Human Immunodeficiency Virus, syphilis, and malaria among blood donors at tertiary care hospital blood bank.

Objective: To ascertain the frequency of markers of transfusion-transmitted infections among blood donors in a tertiary care setting.

Methods: The retrospective cross-sectional descriptive study, was conducted in the Blood Bank section of the Department of Pathology at the Dow University of Health Sciences, Karachi, and comprised data of blood donors from January 2013, to October 2018. All blood donors had been screened for hepatitis B, hepatitis C, human immunodeficiency virus I and II, syphilis through electrochemiluminescence and malaria using immunochromatography.

Frequency Of TP53 Gene Mutation In Patients With Chronic Lymphocytic Leukaemia.

Background: Chronic lymphocytic leukaemia (CLL), an indolent but malignant lymphoproliferative disorder, is characterized by unregulated and uninhibited growth of mature monoclonal lymphocytes, with deletion of 17p containing TP53 gene being the most important prognostic factor. TP53 mutations, reported in 10% of CLL cases, seem to have a direct correlation to a more advanced stage and aggressive transformation of CLL.

Methods: This was a retrospective cross-sectional descriptive study limited to a period from 1st June 2013 to 30th June 2016, conducted at Section of haematology, Department of Pathology and Laboratory Medicine, Aga Khan University Hospital, Karachi.

Tuberculous Granuloma On Bone Marrow Trephine.

Bone marrow examination is a useful tool for diagnosis of many diseases. The utility of bone marrow examination in workup of pyrexia of unknown origin cannot be undermined. Bone trephine of patients presenting with pyrexia of unknown origin must be carefully looked upon for granulomas for evaluation of tuberculosis.

Cerebral Venous Sinus Thrombosis in a Patient with Undiagnosed Factor VII Deficiency.

Factor VII (FVII) deficiency is one of the rare inherited bleeding disorders. Thrombosis has been occasionally described in inherited FVII deficiency. Here, we report a young female with undiagnosed FVII deficiency who presented with cerebral venous sinus thrombosis (CVST).
