Beta-thalassemia major (β-TM) is a genetic disorder, prevalent especially in the Mediterranean region, Southeast Asia, and the Indian subcontinent. With improvements in management over the years, β-TM has transitioned from a fatal childhood disease to a chronic condition. However, in Pakistan, there is still a lack of a comprehensive national policy and strategic plan, which has resulted in a growing number of β-TM patients, placing a substantial burden on individuals and the national healthcare system.

Infections are highly susceptible in patients with hematological malignancies due to immune suppression, immunosuppressive therapies and disease progression. Rational use of antibiotics following Antimicrobial Stewardship (AMS) guidelines in early detection and response to infection is significant to improve patient care. The present study was conducted to determine the impact of clinical pharmacists' interventions (PIs) on antibiotics usage in hematology-oncology set up in Karachi, Pakistan.

A prognostic scoring system that can differentiate β-thalassemia patients based on mortality risk is lacking. We analysed data from 3145 β-thalassemia patients followed through a retrospective cohort design for the outcome of death. An a priori list of prognostic variables was collected.

Transfusion-related complications and lack of resources in low-to-middle-income countries have led to a search for novel therapies to reduce the need for blood transfusions in patients with β-thalassemia. Hydroxyurea (HU) has demonstrated promising outcomes; additionally, thalidomide has also shown improvement in hemoglobin (Hb) levels for patients with β-thalassemia in some studies. This study presents the findings of a single-arm nonrandomized trial to evaluate the efficacy of combination therapy of HU and thalidomide in children with β-thalassemia.

Background: This study focuses on the discovery of protein biomarkers from the maternal serum of β-thalassemic trait mothers carrying the normal fetus and β-thalassemic major fetus.

Methods: Serum samples from β-thalassemic trait mothers carrying major (N = 5) and normal fetuses (N = 5) were studied. The IVS1-5 thalassemia mutation was common among β-thalassemic trait mothers who were carrying a homozygous β-thalassemic fetus (IVS1-5/ IVS1-5 mutation) or a normal fetus (no mutation).

Despite high prevalence and incidence of β-thalassemia in Pakistan, there is very limited work on the use of hydroxyurea (HU) in thalassemia patients in the country. This is the first insight regarding genetic profiling of BCL11A and HU responses in Pakistani β-thalassemia. It correlates single-nucleotide polymorphisms on BCL11A (rs4671393, rs766432) and HBG2 (XmnI), age at first transfusion, and β-globin mutations with HU response in β-thalassemia major (BTM).

Aims: To assess the seasonal variations in hematological disorders among patients diagnosed on the basis of bone marrow biopsy, who attended National Institute of Blood Diseases (NIBD) clinics during 2006 to 2015.

Methods: We retrospectively reviewed the 10-year records of hematological disorders among patients' NIBD clinics from year 2006 to 2015. All cases of aplastic anemia (AA), acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), immune thrombocytopenic purpura (ITP), and acute promyelocytic leukemia (APML) were categorized on the basis of the seasons in which they were diagnosed such as winter (December-February), spring (March-May), southwest monsoon periods (June-September), and retreating monsoon period (October and November).

Background: Beta thalassemia patients, post-bone marrow transplant, and leukemia patients require long term therapy with an intense care follow-up especially for pediatric hematology-oncology origin. Emergence of side effects and noncompliance to therapy lead to reduced efficacy of medicines resulting in relapse of diseases. There is an increasing fact to support the incorporation of a pharmacist into clinical team due to their distinctive skills.

Objective: We assessed the predictive potential of XN-HPC for CD34+ cell count as obtained through Sysmex automated hematology analyzers (XN-1000).

Methods: This study was conducted at the National Institute of Blood Diseases and Bone Marrow Transplantation in 84 donors between December 2012 and December 2017 in the first phase and later validated in 112 donors between December 2017 and December 2018. Sysmex XN-1000 and BD FACS Calibur estimated XN-HPC and CD34+ cells of peripheral blood apheresis product, respectively.

β-thalassemia is a genetic disorder characterized by reduction or absence of β-globin chain with mutations in both copies (β-thalassemia major) or in one copy (β-thalassemia minor). Pregnancies in β- thalassemic carrier women are considered symptom free but have risk of inheriting β-thalassemic fetuses. Current study was designed to compare oxidative stress and antioxidants status in maternal serum from β-thalassemic minor mothers having β-thalassemic major and normal fetuses.

Background: Hydroxyurea (hydroxycarbamide) promotes the production of foetal haemoglobin (HbF) by reactivating gamma-genes. Evidence has shown clinical benefits of hydroxyurea in people with sickle cell anemia; however, only a few studies have assessed this treatment in people with beta (β)-thalassaemia.

Objectives: The primary objective is to review the efficacy of hydroxyurea in reducing or ameliorating the requirement of blood transfusions in people with transfusion-dependent β-thalassaemia.

Background: Nilotinib (Tasigna®) is a second-generation tyrosine kinase inhibitor that shows faster and deeper molecular responses (MR) in comparison to Imatinib as initial therapy in chronic phase chronic myeloid leukemia (CML). Efficacy and safety data for nilotinib in the Asian population is scarce, particularly in Pakistan. We aimed to determine the MR to nilotinib and its safety profile in patients with chronic phase CML.

β-Thalassemia is a widespread autosomal recessive blood disorder found in most parts of the world. Fetal hemoglobin (HbF), a form of hemoglobin is found in infants, replaced by adult hemoglobin (HbA) after birth. Hydroxyurea (HU) is one of the most effective HbF inducer used for the treatment of anemic diseases.

Augmentation of fetal hemoglobin (HbF) production has been an enduring therapeutic objective in β-thalassemia patients for which hydroxyurea (HU) has largely been the drug of choice and the most cost-effective approach. A serum metabolomics study on 40 patients with β-thalassemia prior to and after administration of HU was done along with healthy controls. Treated patients were divided further into non-responders (NR), partial (PR) and good (GR) per their response.

β-Thalassemia is a genetic disorder caused by defects in the β-globin gene resulting in the absence or reduced synthesis of adult hemoglobin (HbA). Hydroxyurea is an effective drug to increase fetal γ-globin (HbF) expression, replacing the missing adult β-globin. The mechanism of HbF induction by hydroxyurea and improvement in clinical symptoms are still poorly understood.

Reactivation of hepatitis B virus (HBV) and hepatitis C virus (HCV) and febrile neutropenia (FN) are common in diffuse large B-cell lymphoma (DLBCL) patients undergoing cyclophosphamide, hydroxyrubicin, Oncovin, and prednisolone (CHOP) or cyclophosphamide, hydroxyrubicin, Oncovin, prednisolone - rituximab containing (R-CHOP) chemotherapy. This ultimately leads to delaying the therapy, increasing hospital stay, and raising the pharmacoeconomic burden on patients. The aim of this study was to determine the incidence of HBV and HCV infection and febrile neutropenia in DLBCL patients treated with R-CHOP and CHOP.
