AbstractThe development of hemolytic erythrocyte alloantibodies and autoantibodies complicates transfusion therapy in thalassemia patients. These antibodies ultimately increase the need for blood and intensify transfusion complications. There is a scanty data on the frequency of RBC alloimmunization and autoimmunization in Egyptian β thalassemia patients as pretransfusion antibody screening is not routinely performed. We studied the frequency of alloimmunization and autoimmunization among 200 multiply transfused β thalassemia patients and investigated the factors that possibly affect antibody formation. Of the 200 patients in our study, 94 were males and 106 females, with the age range of 2–37 years. Alloantibodies were detected in 36 (18%) of the patients, while autoantibodies were detected in 33 (16.5%). The dominant alloantibodies were directed against Kell (33%) and Rh (24.4%) groups. Alloimmunization had a significant relationship with treatment duration and the frequency of transfusion (P = 0.007, 0.001, respectively). The presence of autoantibodies was significantly related to age (P = 0.001), total number of transfused units (P = 0.000) and splenectomy (P = 0.000). The high prevalence of alloimmunization in the study population disclosed the need for providing phenotypically matched cells for selective antigens especially for Kell and Rh subgroups to reduce risk of alloimmunization and increase the efficiency of blood transfusion.

A total of 258 voluntary blood donors (males 101; females 157) in the age range of 18-52 yr among males and 18-55 yr among females were examined for Toxoplasma gondii antibodies (IgG), and (IgM) by immunological technique (Enzyme linked Immunosorbant Assay) during the period from March 2009 to April 2010. This study covered a wide range of factors including immunological, age ,sex , place of residence and symptoms that may have a possible relationship with toxoplasmosis. Results presented in this study showed clearly that 38 (14.7%) of individuals participated in this study having IgG Toxoplasma Ab, among those 10 samples (9.9%) were males and 28 samples (17.8%) were females. Moreover, we found the prevalence of IgM seropositivity in the study population to be 5.8% ,as well as, the prevalence of IgM was 1.98 % in males and 8.3% in females. In addition to , the results of current study indicated that the seroprevalence of IgG Toxoplasma antibodies are more than IgM antibodies ,besides , the peak period range of toxoplasma gondii antibodies IgG among males donors was 30 to 39 years, while among female donors, the highest detection of Toxoplasma gondii antibodies IgG was between the ages of 40 to 49. What's more, the peak age range of Toxoplasma gondii antibodies IgM among males and females donors was 19 to 29 years. In conclusion , Our study showed a high prevalence of T. gondii antibodies in healthy voluntary blood donors. It may be appropriate to include screening test (ELISA) for T. gondii also in the pre transfusion blood testing schedule.

Background: Human non-polio enteroviruses (NPEVs) have been associated with certain life-threatening disorders in children. However, there is paucity of NPEV infection data in most developing countries. This study determined the 3-year prevalence of non-polio enteroviruses (NPEVs) among children in some Northern States of Nigeria. Materials and Methods: Duplicate stool samples were collected from 27778 children ≤15 years. These samples were processed and analyzed for characteristic NPEVs cytopathic effects (CPE) on L20B and RD cell lines. Tests were considered positive if the duplicate samples produced distinct CPE on both cell lines. Results: Of the 27778 samples processed, 3991 (14.4%) NPEVs were isolated. Participants of the male gender (14.5%) within the age range of 0-5 years (14.7%) from Yobe state (15.3%) whose samples were received in the month of June (22.2%) and in the year 2015 (18.8%) had the highest prevalence of NPEVs. June had significant risk factors of NPEVs (p˂0.001, OR=1.95 [95%CI: 1.60-2.34]). However, there was no significant association between age, sex and location of sample collection with the prevalence of NPEV (p˃0.05) Conclusions: This study revealed a relatively high prevalence of NPEVs among the study population. This calls for the need for government implementation of consistently improved water, food and environmental hygiene.

Background: The use of antipsychotic long-acting injections (LAI) aims to reduce risk of relapse and hospitalisation in patients with schizophrenia compared with oral medication. Paliperidone palmitate is currently the only LAI that can be administered at three-monthly intervals for maintenance treatment of schizophrenia. Aim: This prospective study aimed to evaluate relapse and continuation in licensed use of paliperidone palmitate three-monthly (PP3M) over a 2-year follow-up in clinical practice. Method: Non-interventional, observational study of patients treated in the South London and The Maudsley NHS Foundation Trust. Results: A total of 166 patients initiated on PP3M, 55 were excluded from the study (non-F20 diagnosis ( n = 43); F20 >65 years old ( n = 12)). Of the 111 patients included, 67 (60%) continued PP3M for 2 years. Overall 102 patients received more than one dose of PP3M and 92 (90%) remained on the same dose of PP3M for the whole of their treatment duration. Relapse (defined as a step-up in clinical care) occurred in eight patients (7%) while on PP3M. The most common reason for discontinuation was patient refusal and the most frequent medication prescribed after discontinuation was paliperidone palmitate one-monthly (PP1M). Post hoc, we analysed outcome in those continuing any form of PPLAI (those continuing with PP3M and those switching back to PP1M). Continuation over 2 years with any PPLAI formulation was 73% (81/111) and relapse was recorded in 9% (10/111). Conclusion: Overall, PP3M was an effective maintenance treatment for schizophrenia after stabilisation on PP1M in a clinical setting.

Background: Sickle cell disease (SCD) is an important risk factor for stroke in children. Natural history studies demonstrate that greater than 10% of hemoglobin SS patients suffered ischemic stroke prior to age 20 years. In 1998, the Stroke Prevention Trial in Sickle Cell Anemia (STOP) successfully demonstrated the role for routine transfusion therapy in reducing stroke in at risk SCD patients. Fullerton and colleagues then found that first time stroke in SCD decreased in Californian children in the 2 years following STOP. We investigated the stroke rate and health care utilization of children with SCD for two calendar years in the decade following publication of the STOP trial using a national inpatient database. Methods: The 2000 and 2009 Kids’ Inpatient Database (KID) were used for analysis. SCD and stroke cases were identified by ICD-9 codes 282.6x, 430, 431, 432.9, 434.X1, 434.9, 435.9. We queried the KID procedural clinical classification software for utilization of services pertinent to SCD and stroke; transfusion, MRI, and cerebral angio. Results: In 2000, SCD was a discharge diagnosis in 34,294 children and 158 (0.46%) children had SCD and stroke. By 2009, discharges with SCD rose to 37,082 children with 212 (0.57%) children carrying both diagnoses. In 2000 and 2009, AIS is the most common stroke type at 83%, males account for 53% of stroke and black race was reported by 92% of SCD and stroke subjects. Procedure utilization is higher in the SCD and stroke population than in SCD without stroke (Figure 1). Blood transfusion is the most common procedure in both study years, significantly higher in stroke subjects. Conclusion: For pediatric inpatients with SCD, blood transfusion and diagnostic cerebrovascular procedures were significantly more common in the cohort with comorbid stroke. In the decade after STOP, children hospitalized with SCD and stroke represented less than 0.6% of the total inpatient SCD population.

Electroencephalography (EEG) remains an important investigative tool in supporting the diagnosis and classification of various seizure types. We sought to examine and characterize the EEG findings from all patients referred for the procedure. This cross-sectional retrospective study was carried out at an EEG unit in Federal Medical Centre, Makurdi, Benue State, North Central Nigeria from May 2016 to December 2020. Relevant patients' information were extracted and analysed using SPSS version 21. A total of 484 patients were seen over the study period with age range of 1-87 years and median age of 23 years. They comprised of 254 (52.5%) male and 230 (47.5%) female. The psychiatrist and the Physicians/Neurologist referred most of them for EEG, 201 (41.5%) and 124 (25.6%) respectively. The most reported indication for EEG was clinical suspicion of seizure disorder 291 (60.1%), whilst some did not have a clear indication 111 (22.9%). About 417 (86.2%) of our patients had abnormal EEG finding out of which 414 (99.3%) were diagnostic of seizure disorder made up of generalized seizure in 255 (61.6%) and focal seizure in 159 (38.4%). About 237 (48.9%) of them were already on antiepileptic drugs (AEDs) at referral of which 190 (80.2%0 were taking carbamazepine. This study showed a high prevalence of abnormal EEG with most of them diagnostic of seizure disorder especially generalized seizure. They were mostly of younger age group with about half of them already on AEDs at referral, majority of who were sent by the Psychiatrist.

Abstract Background Sickle cell disease can affect retina of eye via vaso-occulsive changes that occur in micro-vessels of retina which could be analysed by using Fundus Fluorescein Angiography. Aim To analyze macular microvascular alternation in patients with SCD by Fundus Fluorescein Angiography (FFA) and to assess the role of potentially contributory Clinico-pathological factors including Trans-Cranial Doppler, genotypes, hydroxyurea, transfusion therapy and finally iron overload state on the development of macular alterations. Method This was across-sectional study which included 30 Sickle cell disease patients randomly recruited from the Paediatric Haematology clinic, children Hospital, Ain Shams University, Cairo, Egypt. Complete blood count (CBC), Trans-Cranial Doppler (TCD) and Fundus Fluorescein Angiography. Results In our study, there were 30 patients with mean age (14.1± 4.02), 5 patients had abnormal/conditional Trans-Cranial, 15 patients had Vaso-occlusive crises, 11 patients were on regular simple blood transfusion; all 30 studied sickle cell disease patients had normal Fundus Fluorescein Angiography and eye examination and only one patient hadabnormal visual acuity;A 29 years oldgirl who had five attacks of cerebral strokes last year, on regular simple blood transfusion and Hydroxyurea treatment with abnormal TCD and recurrent Vaso-occlusive crises in last two years, Although her vision is hand movement yet Fundus Fluorescein Angiography was normal. Conclusion we didn’t find any Retinal microvascular alternation in our studied SCD patients using Fundus Fluorescein Angiography, we related our results to the fact that our studied SCD patients were young and all our studied patients were on hydroxyurea therapy with fair compliance, further studies using large sample size are warranted in order to illustrate the utility of Fundus Fluorescein Angiography (FFA) as a tool for better detection of sickle retinopathy.
