Transcobalamin deficiency - a rare genetic defect in transportation of cobalamin; case report.

BACKGROUND: Vitamin B12 is primarily transported from plasma to cells by Transcobalamin. Deficiency of Transcobalamin is a rare autosomal recessive disorder that results in unavailability of cobalamin in cells and accumulation of homocysteine and methylmalonic acid. CASE REPORT: We report a case of a 2-year-old male child with persistent pancytopenia, recurrent infections, and megaloblastic anemia. Next-generation sequencing identified a novel variant in exon 8 of TCN2 gene. Substantial improvement has been observed following administration of high doses of parenteral methylcobalamin. CONCLUSION: In patients with unresolved pancytopenia and megaloblastic anemia, Transcobalamin deficiency should be investigated and treated promptly to prevent any irreversible and harmful outcome.

Antibiotic Stewardship: A Handshaking Strategy Among Physicians and Pharmacists to Improve therapeutic Outcomes in Hematology-Oncology.

Background: 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. Objectives: 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. Methodology: An observational prospective study was conducted for a period of 4 months in a well-known 75-bed teaching hospital, specializing in bone marrow transplantation in Karachi, Pakistan without a structured Antimicrobial stewardship programs (ASPs). The information was gathered from patient medical histories, laboratory, and microbiological records. Results: A total of 876 PIs (1 to 5 per patient) were implemented. Dose modifications or interval changes accounted for the major interventions (n = 190, 21.6%). The majority of all recommendations were related to antipseudomonal ß-lactams, aminoglycosides, sulfamethoxazole-trimethoprim and vancomycin. Overall, 94.3% (n = 876) of the 928 PIs were accepted. Conclusion: The PIs and the high physician acceptance rate may be useful for improving the safe use of antibiotics, lowering their toxicity, lowering the need for special-vigilance medications and potentially improving patient care.

Development of a Thalassemia International Prognostic Scoring System (TIPSS).

A prognostic scoring system that can differentiate ß-thalassemia patients based on mortality risk is lacking. We analysed data from 3145 ß-thalassemia patients followed through a retrospective cohort design for the outcome of death. An a priori list of prognostic variables was collected. ß Coefficients from a multivariate cox regression model were used from a development dataset (n = 2516) to construct a formula for a Thalassemia International Prognostic Scoring System (TIPSS) which was subsequently applied to a validation dataset (n = 629). The median duration of observation was 10.0 years. The TIPSS score formula was constructed as exp (1.4 × heart disease + 0.9 × liver disease + 0.9 × diabetes + 0.9 × sepsis + 0.6 × alanine aminotransferase ≥42 IU/L + 0.6 × hemoglobin ≤9 g/dL + 0.4 × serum ferritin ≥1850 ng/mL). TIPSS score thresholds of greatest differentiation were assigned as <2.0 (low-risk), 2.0 to <5.0 (intermediate-risk), and ≥5.0 (high-risk). The TIPSS score was a good predictor for the outcome of death in the validation dataset (AUC: 0.722, 95%CI: 0.641-0.804) and survival was significantly different between patients in the three risk categories (P < 0.001). Compared to low-risk patients, the hazard ratio for death was 2.778 (95%CI: 1.335-5.780) in patients with intermediate-risk and 6.431 (95%CI: 3.151-13.128) in patients with high-risk. This study provides a novel tool to support mortality risk categorization for patients with ß-thalassemia that could help management and research decisions.

Primary HBB gene mutation severity and long-term outcomes in a global cohort of ß-thalassaemia.

In ß-thalassaemia, the severity of inherited ß-globin gene mutations determines the severity of the clinical phenotype at presentation and subsequent transfusion requirements. However, data on associated long-term outcomes remain limited. We analysed data from 2109 ß-thalassaemia patients with available genotypes in a global database. Genotype severity was grouped as ß0 /ß0 , ß0 /ß+ , ß+ /ß+ , ß0 /ß++ , ß+ /ß++ , and ß++ /ß++ . Patients were followed from birth until death or loss to follow-up. The median follow-up time was 34·1 years. Mortality and multiple morbidity outcomes were analyzed through five different stratification models of genotype severity groups. Interestingly, ß0 and ß+ mutations showed similar risk profiles. Upon adjustment for demographics and receipt of conventional therapy, patients with ß0 /ß0 , ß0 /ß+ , or ß+ /ß+ had a 2·104-increased risk of death [95% confidence interval (CI): 1·176-3·763, P = 0·011] and 2·956-increased odds of multiple morbidity (95% CI: 2·310-3·784, P < 0·001) compared to patients in lower genotype severity groups. Cumulative survival estimates by age 65 years were 36·8% for this subgroup compared with 90·2% for patients in lower genotype severity groups (P < 0·001). Our study identified mortality and morbidity risk estimates across various genotype severity groups in patients with ß-thalassaemia and suggests inclusion of both ß+ and ß0 mutations in strata of greatest severity.

A Pragmatic Scoring Tool to Predict Hydroxyurea Response Among ß-Thalassemia Major Patients in Pakistan.

Despite high prevalence and incidence of ß-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 ß-thalassemia. It correlates single-nucleotide polymorphisms on BCL11A (rs4671393, rs766432) and HBG2 (XmnI), age at first transfusion, and ß-globin mutations with HU response in ß-thalassemia major (BTM). Of 272 patients treated with HU, 98 were complete responders, 55 partial responders, and 119 nonresponders. Our analysis shows that HU response was significantly associated with patients having IVSI-1 or CD 30 mutation (P<0.001), age at first transfusion >1 year (P<0.001), and with the presence of XmnI polymorphism (P<0.001). The single-nucleotide polymorphisms of BCL11A were more prevalent among responders, but could not show significant association with HU response (P>0.05). Cumulative effect of all 5 predicting factors through simple binary scoring indicates that the likelihood of HU response increases with the number of primary and secondary genetic modifiers (P<0.001). Predictors scoring is a pragmatic tool to foresee HU response in patients with BTM. The authors recommend a score of ≥2 for starting HU therapy in Pakistani patients with BTM.

Prenatal diagnosis of maternal serum from mothers carrying ß-thalassemic fetus.

BACKGROUND: This study focuses on the discovery of protein biomarkers from the maternal serum of ß-thalassemic trait mothers carrying the normal fetus and ß-thalassemic major fetus. METHODS: Serum samples from ß-thalassemic trait mothers carrying major (N = 5) and normal fetuses (N = 5) were studied. The IVS1-5 thalassemia mutation was common among ß-thalassemic trait mothers who were carrying a homozygous ß-thalassemic fetus (IVS1-5/ IVS1-5 mutation) or a normal fetus (no mutation). We employed two-dimensional gel electrophoresis and mass spectrometry analysis to explore differentially expressed maternal serum proteins from thalassemia carrier couples with the same ß-thalassemia mutation. Western blotting was performed for one of the identified proteins to validate our data. RESULTS: Ten proteins were identified in the maternal serum of ß-thalassemic trait mothers carrying the ß-thalassemic major fetus and normal fetus. Among these, serotransferrin, haptoglobin, α-1 anti-trypsin, apo-lipoprotein A1, and the fibrinogen-ß chain were found to be upregulated in mothers carrying major fetuses and are known to be associated with pregnancy-related disorders. The expression of α-1 anti-trypsin was validated through western blotting. CONCLUSIONS: Proteins identified in the current study from maternal serum are reported to contribute to hereditary disorders. We suggest that these can serve as putative screening markers for non-invasive prenatal diagnosis in ß-thalassemic pregnancies.

A complication risk score to evaluate clinical severity of thalassaemia syndromes.

The thalassaemia syndromes (TS) show different phenotype severity. Developing a reliable, practical and global tool to determine disease severity and tailor treatment would be of great value. Overall, 7910 patients were analysed with the aim of constructing a complication risk score (CoRS) to evaluate the probability of developing one or more complications. Nine independent variables were included in the investigation as predictors. Logistic regression models were used for Group A [transfusion-dependent thalassaemia (TDT)], Group B [transfused non-TDT (NTDT)] and Group C (non-transfused NTDT). Statistically significant predictors included age (years), haemoglobin levels, hepatic transaminases [alanine aminotransferase (ALT) and aspartate aminotransferase] and left-ventricular ejection fraction (LVEF) for Group A; age (years), age at first chelation (months), ALT and LVEF for Group B; and age (years), mean serum ferritin (SF) levels and LVEF for Group C. The area under the receiver operating characteristic curve was 84·5%, 82·1% and 80·0% for Groups A, Group B and Group C respectively, suggesting the models had good discrimination. Finally, the CoRS for each group was categorised into four risk classes (low, intermediate, high, and very high) using the centiles of its distribution. In conclusion, we have developed a CoRS for TS that can assist physicians in prospectively tailoring patients' treatment.

Incorporating a clinical oncology pharmacist into an ambulatory care pharmacy in pediatric hematology-oncology and transplant clinic: Assessment and significance.

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. Clinical oncology pharmacist with experience and specialized training in hematological cancers and bone marrow transplantation (BMT) patient care has in-depth knowledge and skills of chemotherapy regimens including drug information, monitoring parameters of cancer treatment, dose adjustment, drug-drug interactions, adverse effects, and patient counseling skills. AIM AND OBJECTIVES: The main objective of our study was to assess the significance of incorporation of clinical oncology pharmacist in ambulatory care in pediatric hematology-oncology and transplant clinic. MATERIAL AND METHOD: This study was conducted at National Institute of Blood Diseases and Bone Marrow Transplantation hospital with duration of five months from 17 March 2019 to 16 July 2019. In this study the clinical oncology pharmacist was made available at ambulatory clinic of hematology-oncology and transplantation. The activities performed by a clinical oncology pharmacist were observed by resident BMT clinical pharmacist during the visits of patients and their families in a clinic. The BMT pharmacist is a clinical oncology pharmacist with experience and specialized training in hematological cancers and BMT patient care. Only pediatrics patients with beta thalassemia major and those who were on chemotherapy treatment and post-transplant patient were included in this study. RESULTS: During the five months' tenure, there were 1820 pediatric patients' visits in total. The clinical oncology pharmacist performed 980 direct patient interviews and documented 1665 pharmacist interventions. The majority of the documented clinical oncology pharmacist interventions were review of medication histories (n: 404, 24%) and "deferiprone" dose adjustments (n:400, 24%). Genomic profiling interventions were also among the commonly reported activities by the clinical oncology pharmacist. For beta thalassemia patients undergoing hydroxyurea therapy, the genomic profiling was performed to assess whether the hydroxyurea treatment is clinically effective or not (n:396, 23%). CONCLUSION: The involvement of clinical oncology pharmacist into a specialized outpatient clinic of hematology-oncology and transplant clinic plays an integral role in minimizing the adverse effect and reduction in readmission into the hospital. This is new expansion of pharmacist's role especially in underdeveloped country, considering the relevant clinical participation of clinical oncology pharmacist into specialized clinic revealing through optimized therapy and future prospect of clinical oncology pharmacist in pediatric hematology.

Antioxidant Activity and Oxidative Stress Status in Maternal Serum of ß-thalassemic Mothers Carrying ß-thalassemic Major and Normal Fetuses.

Objectiveß-thalassemia is a genetic disorder characterized by reduction or absence of ß-globin chain with mutations in both copies (ß-thalassemia major) or in one copy (ß-thalassemia minor). Pregnancies in ß- thalassemic carrier women are considered symptom free but have risk of inheriting ß-thalassemic fetuses. Current study was designed to compare oxidative stress and antioxidants status in maternal serum from ß-thalassemic minor mothers having ß-thalassemic major and normal fetuses. Method: We investigated paraoxonase (PON1) and arylesterase (ARE) activities along with malondialdehyde (MDA) and reactive oxygen species (ROS) in maternal serum of ß-thalassemic carrier women. Results: PON1 and ARE activities were found to be significantly decreased, whereas the concentration of MDA and ROS were significantly increased in ß-thalassemic minor mothers with ß-thalassemic major fetuses. Conclusion: The study concludes that redox imbalance in ß-thalassemic trait mothers carrying thalassemic fetuses is higher than in mothers carrying normal fetuses.

Hydroxyurea (hydroxycarbamide) for transfusion-dependent ß-thalassaemia.

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 (ß)-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 ß-thalassaemia. The second objective is to review the safety of hydroxyurea with regards to severe adverse effects in this population. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register, compiled from electronic database searches and hand searching of journals and conference abstract books. We also searched electronic databases and trial registries, including ClinicalTrials.gov, the WHO ICTRP and PubMed (09 October 2018).Date of last search of the Group's haemoglobinopathies trials register: 04 March 2019. SELECTION CRITERIA: Randomised controlled trials of hydroxyurea in people with transfusion-dependent ß-thalassaemia, compared with placebo or standard treatment or comparing different doses of hydroxyurea. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trials for inclusion in the review, which was verified by a third author. MAIN RESULTS: No trials were eligible for inclusion in this review. AUTHORS' CONCLUSIONS: Currently, there is no high-quality evidence to support or challenge the continued use of hydroxyurea for managing people with transfusion-dependent ß-thalassaemia. Multicentre, randomised controlled trials (compared to placebo or other available treatment, i.e. blood transfusion and iron chelation) are needed in order to assess the efficacy and safety of hydroxyurea for reducing the need for blood transfusion, for maintaining or improving mean haemoglobin levels, as well as for determining its cost-effectiveness.

Laboratory diagnosis for thalassemia intermedia: Are we there yet?

BACKGROUND: Differentiation between thalassemia major and thalassemia intermedia at presentation is not uniformly characterized, for which an absolute criteria needs to be developed. This study investigated the primary and secondary genetic modifiers to develop a laboratory finding by forming different genetic mutational combinations seen among thalassemia intermedia patients and comparing them with thalassemia major. METHODS: This cross-sectional study analyzed 315 thalassemia intermedia patients. One hundred and five thalassemia major patients were recruited on the basis of documented evidence of diagnosis and were receiving blood transfusion therapy regularly. Various mutational combinations were identified, and comparison was performed between thalassemia intermedia and major using statistical software STATA 11.1. RESULTS: The mean age of the total population was 5.9 ± 5.32 years of which 165 (52%) were males. Of the two groups (thalassemia intermedia and thalassemia major), IVSI-5, IVSI-1, and Fr 8-9 were more prevalent among the thalassemia intermedia cohort. When comparison was performed between the thalassemia intermedia and thalassemia major patients, it showed significant results for the presence of Xmn-1 polymorphism. CONCLUSION: The presence of IVSI-5 homozygous with Xmn-1, IVSI-5 heterozygous with Xmn-1, Cd 30 homozygous with or without Xmn-1 and IVSI-1 homozygous or heterozygous either with or without Xmn-1 prove to be strong indicators towards diagnosis of thalassemia intermedia.

METHODS: The single-centred, escriptive cros-sectional study was conducted athe National Instiute of Blod Disease and Bone Marow Transplantaion, Karchi, from June 1,2012, to May 31, 2013. Patients of homozygous beta halsaemia, diagnosed by polymerase chain reaction, wer tested for coinheritance of alpha Thalsaemia nd foetal haemoglobin XMN1 polymorphism using polymerase chain reaction. SPS 17 was used for dat anlysi. RESULTS: Of the 286 patients, 19(41.6%) wer males, and 9(34.6%) showed coinheritance ofalpha thalsaemia. In the coinheritance group, 50(50%) and 1(1%) patients recived 1-20 and 21-40 times transfusions per year espectively, while inthe non-coinheritance group, the coresponding numbers wer 125(67%) and 27(14.%). Overal, 73(25.%) patients had nevr ben transfused, including 38(13.%) patients inthe alpha Thalsaemia group. XMN1 polymorphism was found in 86(41%) ofthe 208 patients who wer tested and anlysed on this count. CONCLUSIONS: Alpha thalsemia was presnt inmore than one-third homozygous beta halsemia patients.

Impact of hydroxyurea therapy on serum fatty acids of ß-thalassemia patients.

INTRODUCTION AND OBJECTIVE: Fatty acids (FAs) influence cell and tissue metabolism, function, responsiveness to hormonal and other signals in addition to maintenance of membrane integrity of cells. ß-Thalassemia is a prevalent inherited blood disorder characterized by abnormal red cell membrane structure and function. Induction of HbF by hydroxyurea (HU) is an enduring therapeutic intervention to manage this. Therefore, in the present study we have carried out the quantification of thirteen free fatty acids to disclose the prognosis of HU in ß-thalassemia. METHODS: FAs quantification was carried out using GC-MRM-MS method in the serum of 98 cases of ß-thalassemia patients and out of which samples from 34 patients were collected before and after treatment with HU in addition to healthy controls (n = 31). RESULTS: Using the combination of random forest (RF) with GC-MRM-MS we were able to establish a classification and prediction model that can discriminate the ß-thalassemia from healthy as well as from HU treated group. Docosanoic acid (C-22:0) was most significantly altered in ß-thalassemia as compared to healthy at p-value of 8.3 × 10-09 while erucic acid (C-22:1 Δcis-13) can be used as potential marker of HU prognosis because its level became significantly dissimilar at p-value of 3.7 × 10-04 in same patients in response to HU. However, nervonic acid (C-24:1 Δcis-15) was found to be the key player in effectively separating three groups. CONCLUSION: In inference, we have noticed that HU therapy also rectifies the serum fatty acid profile in addition to its reported affect i.e. HbF induction in ß-thalassemia patients.

Quantitative assessment of metal dysregulation in ß-thalassemia patients in comparison with healthy controls by ICP-MS and chemometric analyses.

ß-Thalassemia is one of the most common inherited disorders and is widely distributed throughout the world. Owing to severe deficiencies in red blood cell production, blood transfusion is required to correct anemia for normal growth and development but causes additional complications owing to iron overload. The aim of this study is to quantify the biometal dysregulations in ß-thalassemia patients as compared with healthy controls. A total of 17 elements were analyzed in serum samples of ß-thalassemia patients and healthy controls using ICP-MS followed by chemometric analyses. Out of these analyzed elements, 14 showed a significant difference between healthy and disease groups at p < 0.05 and fold change >3. A PLS-DA model revealed an excellent separation with 89.8% sensitivity and 97.2% specificity and the overall accuracy of the model was 92.2%. This metallomic study revealed that there is major difference in metallomic profiling of ß-thalassemia patients specifically in Co, Mn, Ni, V and Ba, whereas the fold changes in Co, Mn, V and Ba were found to be greater than that in Fe, providing evidence that, in addition to Fe, other metals are also altered significantly and therefore chelation therapy for other metals may also needed in ß-thalassemia patients.

Detection of the Incidence of HBV, HCV Infection and Febrile Neutropenia Associated With CHOP With or Without Rituximab in Diffuse Large B-Cell Lymphoma-Treated Patients.

Background: 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. Aim and Objective: 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. Methodology: This was an institutional approved study in which patient records from a private hospital, specialized in hematology and oncology (Karachi, Pakistan), were reviewed retrospectively from 2014 to 2016. Patients aged above 18 years with known diagnosis of DLBCL who underwent CHOP-21 or R-CHOP-21 chemotherapy regimen were included. Baseline blood chemistry and liver function tests along with the data regarding HBV (hepatitis B surface antigen [HBsAg], hepatitis B surface antibody [anti-HBs]), HCV (antibody anti-HCV), and febrile neutropenia were collected from patient records. Results: In total, 35 cases of DLBCL were treated during a 3-year period (ie, from 2014 to 2016), of which 16 were on CHOP-21 regimen whereas 19 were treated with R-CHOP-21. Of the 19 patients who underwent R-CHOP chemotherapy, only 2 (10%) patients were HBsAg reactive. Before commencing the second cycle, 2 (10%) patients reported to hospital with fever and had hematological (low neutrophil count) and microbiological (Escherichia coli) proven febrile neutropenia. The incidence of HBV infection post treatment was lower in group treated with CHOP (1 patient showed HBsAg reactivity).

Alpha thalassemia deletions found in suspected cases of beta thalassemia major in Pakistani population.

BACKGROUND & OBJECTIVE: Alpha (α) thalassemia is a hereditary disorder and is caused by deletions or mutations in globin genes. It is present in two clinically significant forms: hemoglobin Bart hydrops fetalis (Hb Bart) syndrome and hemoglobin H (HbH) disease. It is highly prevalent in South-East Asia or Mediterranean countries. The most common deletion reported in alpha thalassemia in Pakistani population was -α3.7 with a frequency of 8.3%, and the rare forms were -α4.2 (0.2%) and αααanti3.7 (0.9%). In our study, diagnosis of severe anemia cases without any α and ß mutations or deletions were made by using extended alpha thalassemia deletions panel. The main objective of this study was to determine the prevalence and to study the spectra of alpha thalassemia gene deletions in beta thalassemia patients with the use of an extended panel including --SEA, --FIL, --MED, --20.5, --THAI in addition to -α3.7, -α4.2 & -αααanti3.7. METHODS: The samples were collected in ethylenediaminetetraacetic acid (EDTA) vacutainers. A total of 156 samples were analyzed for alpha thalassemia mutations. This cohort included 121 samples of beta thalassemia major, nine samples of beta thalassemia minor and 26 without any evidence of beta thalassemia mutations. DNA was extracted with Qiagen extraction kit. The primers for determination of different subsets of alpha thalassemia deletions were included. PCR amplification was performed and result interpreted on agarose gel. RESULTS: Co-inheritance of alpha thalassemia (-α3.7, -α4.2) with homozygous beta thalassemia was detected in 30% cases of studied cohort (37 out of 121). The most common found was -α3.7 deletion (35/37) as single/double deletions or in combination with -αααanti3.7. In undiagnosed cases screened for beta thalassemia major, we found Mediterranean (-αMED) deletion at specifically 875 bp on agarose gel. This is distinctive finding in case of detecting -αMED instead of any other deletion from Pakistan. CONCLUSION: Alpha thalassemia deletions (-α3.7, -α4.2) are the common co-inherited deletions found in beta thalassemia major patients. On the basis of results, we propose an extended alpha thalassemia genetic mutation panel should be used for screening of children presenting with anemia with suspicion of haemoglobinopathy.

Sensitivity and specificity of single-tube osmotic fragility test and its different methods as screening test for thalassemia trait: an alternative to expensive laboratory tests for resource-limited countries.

OBJECTIVE: To determine the sensitivity and specificity of single-tube osmotic fragility (SOFT) and its different methods as screening test for thalassemia trait. METHODS: A cross-sectional study was conducted at Omair Sana Foundation. A total of 400 participants were included in the study. Three hundred were known thalassemia carriers (parents with at least one child with thalassemia major), while 100 were healthy blood donors. SOFT was performed on all 400 participants. Serum iron, ferritin, and DNA tests were performed on 100 participants (donors). ARMS technique was used for detecting thalassemia mutations. RESULTS: Sensitivity and specificity of SOFT (venous method) were found to be 99.6% and 86%, respectively, while with EDTA method, sensitivity was 95% and specificity was 96%. For venous and EDTA methods, positive predictive values were 95.5% and 98.6%, respectively, while negative predictive values were 98.8% and 86.6%, respectively. Use of EDTA and storage had an effect on the results. Sensitivity of SOFT was 95% at 5 min, while it decreased to 87% with EDTA method at 240 min. Sensitivity of SOFT for iron deficiency anemia was found to be 14%. CONCLUSION: SOFT can be used as screening test for thalassemia trait in a cost-effective way. Moreover, we also found that SOFT should be performed on venous blood without adding preservatives (EDTA) that can interfere with the results.

Exploring the perceptions and experiences of female's with ß-thalassemia major in a Tertiary Care Private Hospital in Pakistan.

INTRODUCTION: ß-Thalassemia, a genetic condition which influences both the physical and emotional facets of individuals specially females while also exerting substantial financial strain on families and healthcare systems. Recognizing the pivotal influence of social support, particularly on mental well-being, this study endeavors to delve into the shared psychosocial challenges experienced by females grappling with ß-thalassemia major. METHODS: Employing a qualitative-descriptive methodology and purposive sampling, this study conducted in-depth interviews with forty-two young girls, 18.64 ± 4.27, diagnosed with ß-thalassemia major and representing diverse academic backgrounds, using a semi-structured in-depth interview guide. NVIVO-12 software facilitated extended data analysis, encompassing coding, categorization, theme development, and mind-mapping techniques to unravel nuanced insights from the collected data. FINDINGS: This groundbreaking study delves into the psychosocial factors that impact the well-being of female ß-thalassemia patients. The research highlights the key factors that positively contribute to their quality of life by conducting thorough inductive content analysis. These include receiving an education, having robust family support, experiencing overall life satisfaction, and making meaningful societal contributions. The findings of this study can be used to improve the lives of female ß-thalassemia patients and enhance their overall well-being. Contrariwise, notable impediments encompassed depression, social isolation, limited access to insurance services, challenges in educational and employment spheres, as well as difficulties in nurturing social relationships. These findings underscore the multifaceted influences shaping the quality of life for girls navigating ß-thalassemia, shedding light on empowering and challenging elements within their experiences. CONCLUSION: In conclusion, psychosocial factors supporting or hindering the well-being of young girls with ß-thalassemia major in Pakistan include an inductive environment at homes, organizations, education, institutions with adequate knowledge of thalassemia disease among patients, and society. More research is needed to understand their needs and advocate for societal support and acceptance. Family and friends support are crucial for improving their quality of life, necessitating focused efforts to provide understanding and aid within the community.
