The glutathione S-transferase (GST) genes encode enzymes that mediate the detoxification of xenobiotics by catalyzing the conjugation of glutathione (GSH) to xenobiotic substrates. The aim of the current study is to investigate the association between GSTT1 and GSTM1 polymorphisms and chronic myeloid leukemia (CML) among Sudanese patients. Patients with CML (n = 115) were recruited to the study from the Radiation and Isotope Centre Khartoum (RICK)-Sudan. Healthy individuals (n = 104) were included as controls. Genotyping of GSTT1 and GSTM1 polymorphisms was performed using multiplex PCR. Null deletions in the GSTT1 and GSTM1 genes are common in the Sudanese population (control group), with frequencies of 33.9% and 38.2%, respectively. The frequencies of GSTT1 (OR: 3.25, 95% CI: 1.87–5.65, p < 0.001) and GSTM1 (OR: 2.14, 95% CI: 1.25–3.67, p < 0.005) null genotypes were significantly higher in CML patients vs. controls. The distribution of GSTT1 and GSTM1 null polymorphisms was not different between male and female (p > 0.01) and young and old CML patients (p > 0.05). Hematological parameters were not affected by null polymorphisms in the patient group (p > 0.05). In addition, the frequency of GSTM1 null polymorphism was lower in advanced-phase CML patients compared to chronic-phase patients (p < 0.05). The GSTT1 and GSTM1 null polymorphisms are associated with CML among Sudanese patients, independently of their age and gender.
Covid-19 is a severe acute respiratory syndrome, the disease presents with a ranging from asymptomatic to severe symptomatic illness with multiple organ failure and death, and can cause a severe effect on the coagulation system. This study aimed to determine the effect of the covid 19 on the extrinsic and intrinsic pathway of coagulation [prothrombin time(PT), international normalized ratio (INR), and activated partial thromboplastin time (APTT)] and to determine the association of age and gender with the severity of COVID-19 in Sudan in order to improve the outcome. A cross-sectional study carried out among 487 COVID-19 patients attending Khartoum State. COVID-19 patients were confirmed by RT-PCR. For all patients, the prothrombin times (PT), International normalized ratio (INR), and Activated partial thromboplastin (APTT) were estimated by using a semi-automated coagulometer analyzer. Patients were divided into three subclass groups according to the Severity of COVID-19 (mild, severe in the emergency room (ER) and intensive care unit (ICU), and the clotting factors values were compared between the groups. The results were statically analyzed by spss version 21 for data analysis. These results showed statistically significant increased Levels of PT, INR, and APTT for all (P. value = 0.000), compared to the control group. Also, the levels of coagulation tests were higher in ICU COVID-19 patients (P. value = 0.000) compared to mild and severe subgroups. This study concluded that: coagulation clotting times were increased in COVID-19 patients, especially among patients in ICU which could be a marker for DIC and even death.
Background: Traditional medicine had been used alongside synthetic pharmaceutical products to enhance health management. Due to the high mortality rate of sickle cell patients, previous studies have been indicated that some medicinal plants have shown an anti-sickling activity, which indicates a new therapeutic way to manage people who are affected by these disorders. The current study aimed to assess in vitro-anti-sickling activity of Hyphaene thebaica (H thebaica) (Doum) fruit. Materials and methods: Blood samples used in the evaluation of the anti-sickling activity of Hyphaene Thebaica Fruits extract in this study was taken from patients known to had Sickle cell disease (HB -SS ) attending the Sickle Cell Clinic in Khartoum state. Emmel test was used to assess anti-sickling activity of this plant. Result: A significant increase in the percentage of unsickled Red blood cells with p-value 0.05 >was observed after incubation of RBCs with 2% sodium metabisulfite in the presence of three different concentration (1000, 500 and 250) μg/ml of Hyphened thebaica for two type of extraction (aqueous and methanol) extract. Conclusion: This study approved that H.thebaica (Doum ) fruit extract had a strong anti- sickling activity ; it could be used for management of sickle cell disease.
Hemolytic disease of newborn (HDN) consequences lead to considerable morbidity and mortality, and so immediate diagnosis and treatment to prevent serious repercussions are crucial. Since investigative and preventative measures of hemolytic disease of the fetus and newborn (HDFN) in Sudan lack adherence to standard international protocols (due to a lack of adequate antenatal care), this study may be useful in improving quality of life. The present study aimed to determine different hematological parameters (Hb, HCT, RBC, and erythroblast values) and maternal–fetal ABO blood type incompatibility among Sudanese jaundiced neonates with HDN. A descriptive cross-sectional study was carried out on 305 mothers and their fetuses admitted to Omdurman Maternity Hospital, Sudan. ABO and rhesus (RhD) blood groups, direct antiglobulin test (DAT), CBC, and a comment on blood smear were determined for the jaundiced newborns and used for data analysis. The history of total bilirubin, direct bilirubin level, mother’s age, gestational age, weight, gender, phototherapy, blood exchange, and presence of fever of neonates were recorded during the study. Statistical data analysis was performed using SPSS Software Version 16. The overall frequency of HDN with positive DAT was 57 (18.9%). RhD, ABO, and other blood group system incompatibility in HDN were 4 (1.3%), 18 (5.9%), and 35 (11.4%), respectively. There was statistical significance in total and direct bilirubin, gestational age, transfusion history, and phototherapy. There was a highly significant association between a positive Coomb’s test and the presence of abnormal peripheral cells (spherocyte, NRBCs, polychromasia, and target). This study revealed that the prevalence of HDFN with hyperbilirubinemia was 57 (18.9%), which remains a challenge due to the lack of standard protocols in Sudan. RhD remains the most significant antigen contributing to HDFN, although prophylactic anti-D was used. There was a significant association between DAT and abnormal blood cells.
Burkitt lymphoma, one of the two main types of B-cell non-Hodgkin lymphomas (B-NHL), is a cancer type that develops in the lymphatic system and is a very aggressive lymphoma. This study looked into the cytogenetic and molecular characteristics of Burkitt lymphoma in Sudanese individuals. Paraffin embedded tissue blocks associated to 34 people who had previously been diagnosed with burkitt's lymphoma and retained were studied as part of a retrospective cross-sectional study in Khartoum state, Sudan, in September 2017. The Soba Teaching Governmental Hospital and private histology laboratories provided these blocks. The analysis component included three translocations, including t(8;14) (q24;q32), t(8;22) (q24;q11), and t(2;8) (p12;q24) for 34 patients. We discovered that the majority of patients have t(8;14) (q24;q32), which was positive in 44.1% (15/34), while t(8;22) (q24;q11) verified in 17.6% (6/34) of patients. Only one (2.9%) displays a positive result for t(2; 8) (p12;q24). Although immune-phenotyping and morphological characteristics for BL were found in the study's 12 cases (35.3%), it is possible that these cases represent a different variety of Burkitt's lymphoma caused by different forms of translocation. According to the study's findings, t(8;14) (q24;q32) remains the most common chromosomal rearrangement among Sudanese individuals with BL. Nevertheless, translocation of BL variations may exist, necessitating the use of advanced tools like sequencing, as these variants may play a significant role in the development and prognosis of disease.
