Abstract Objectives Studies have not addressed microalbuminuria in the sickle cell disease (SCD) pediatric population in Jeddah, Saudi Arabia. This study aimed to determine the prevalence of microalbuminuria and to identify associated risk factors in children with SCD in the King Abdulaziz University Hospital.Results Overall, 42.5% of the patients enrolled were Saudi Arabian and 51% were boys. Patients’ mean age was 12.4 years, and the highest percentage (40%) was in the age group of 15–18 years. The prevalence of microalbuminuria was 9.6%, and hematuria was present in 8% of cases. The percentage of patients with hematuria in the microalbuminuria group (22.6%) was significantly higher than that in the non-microalbuminuria group (6.5%) (P=.007). The percentage of patients with acute chest syndrome was higher in the microalbuminuria group (26%) than in the non-microalbuminuria group (8%) (P=0.005). The percentage of patients with gallbladder stones was higher in the microalbuminuria group (13%) than in the non-microalbuminuria group (2.4%) (P=.014). The mean number of blood transfusions was higher in the non-microalbuminuria group than in the microalbuminuria group (P=.002). Sickle cell nephropathy manifests as microalbuminuria, begins in the early ages of life, occurs in all types of SCD, and is associated with disease severity.

Abstract Placenta growth factor (PlGF) is released by immature erythrocytes and is elevated in sickle cell disease (SCD). Previous data generated in vitro suggest that PlGF may play a role in the pathophysiology of SCD-associated pulmonary hypertension (PHT) by inducing the release of the vasoconstrictor, endothelin-1. In this cross-sectional study of 74 patients with SCD, we confirm that PlGF is significantly elevated in SCD compared with healthy control subjects. We found significantly higher levels of PlGF in SCD patients with PHT but observed no association of PlGF with the frequency of acute pain episodes or history of acute chest syndrome. The observed correlation between PlGF and various measures of red cell destruction suggests that hemolysis, and the resultant erythropoietic response, results in the up-regulation of PlGF. Although relatively specific, PlGF, as well as N-terminal pro-brain natriuretic peptide and soluble vascular cell adhesion molecule, has low predictive accuracy for the presence of PHT. Prospective studies are required to conclusively define the contribution of PlGF to the pathogenesis of PHT and other hemolytic complications in SCD.

Background. Transfusion of red blood cells (RBC) is an essential therapeutic tool in sickle cell disease (SCD). Repeated RBC transfusions can cause alloimmunization which causes difficulty in cross-matching and finding compatible blood for transfusions. This study aimed to investigate the frequency of RBC alloimmunization and related risk factors among Palestinian SCD patients.Materials and Methods. A multicenter cross-sectional study on 116 previously transfused SCD patients from three centers in West Bank, Palestine. Demographic, medical data and history of transfusion were recorded. Blood samples were collected from transfused consenting SCD patients. Gel card method was used for antibody screening and identification. In all patients, autocontrol and direct antiglobulin (DAT) test were performed using polyspecific (anti-IgG + C3d) anti-human globulin (AHG) gel cards for the detection of autoantibodies.Results. Of the SCD patients, 62 (53.4%) patients were HbSS and 54 (46.6%) patients were sickleβ-thalassemia (S/β-thal). There were 53 (45.7%) females and 63 (54.3%) males. Mean age was 18.8 years (range 3-53 years). The frequency of RBC alloimmunization among SCD patients was 7.76%, with anti-K showing the highest frequency (33.3%) followed by anti-E (22.2%), anti-D (11.1%), anti-C (11.1%), and anti-c (11.1%). All reported IgG alloantibodies were directed against antigens in the Rh (66.7%) and Kell (33.3%) systems. Older ages of patients, increased number of blood units transfused, and splenectomy were the commonest risk factors for alloimmunization in our study.Conclusions. RBC alloimmunization rate among Palestinian SCD patients is low compared to neighboring countries and countries all over the world but still warrants more attention. Phenotyping of donors/recipients’ RBC for Rh antigens and K1(partial phenotype matching) before their first transfusion may reduce the incidence of alloimmunization.

Patients with sickle cell disease are more likely to undergo surgery during their lifetime, especially given the numerous complications they may develop. There is a paucity of data concerning the management of patients with sickle cell disease by anaesthesiologists, especially in Africa. This study aimed to describe the practices of anaesthesiologists in Cameroon concerning the perioperative management of patients with sickle cell disease. A cross-sectional study was carried out over four months and involved 35 out 47 anaesthesiologists working in hospitals across the country, who were invited to fill a data collection form after giving their informed consent. The data were analysed using descriptive statistics and a binary logistic regression model. Among the 35 anaesthesiologists included in the study, most (29 (82.9%)) had managed patients with sickle cell disease for both emergency and elective surgical procedures. Most of them had never asked for a haematology consultation before surgery. Most participants (26 (74.3%)) admitted to having carried out simple blood transfusions, while 4 (11.4%) carried out exchange transfusions. The haemoglobin thresholds for transfusion varied from one practitioner to another, between < 6 g/dl and < 9 g/dl. Only 6 (17.1%) anaesthesiologists had a treatment guideline for the management of patients with sickle cell disease in the hospitals where they practiced. Only 9 (25.7%) prescribed a search for irregular agglutinins. The percentage of haemoglobin S before surgery was always available for 5 (14.3%) of the participants. The coefficient (0.06) of the occurrence of a haematology consultation before surgery had a significant influence on the probability of management of post-operative complications (coefficient 0.06, 10% level of probability). This study highlights the fact that practices in the perioperative management of patients with sickle cell disease in Cameroon vary greatly from one anaesthesiologist to another. We disclosed major differences in the current recommendations, which support the fact that even in Sub-Saharan countries, guidelines applicable to the local settings should be published.

Introduction: Sickle Cell Disease (SCD) is an inherited chronic haemolytic anaemia. The diseased person suffers from various complications such as anaemia, frequent infection, fever, hand-foot syndrome, stroke, etc. Puberty changes includes the appearance of the secondary sexual characteristics, increase in height, change in body composition and development of reproductive capacity. Aim: To study the sexual maturity and effect of multiple blood transfusions in adolescents suffering from SCD. Materials and Methods: It was a cross-sectional study conducted on 35 adolescents of age group 11 to 15 years, suffering from SCD. Study was conducted over a period of six months from March 2018 to September 2018 at Department of Paediatrics. SCD was diagnosed by Haemoglobin (Hb) electrophoresis. Weight and height were measured of all the participants. For assessing the sexual maturity, Tanners staging was used. Unpaired t-test was done for data analysis. Results: The mean age of the patients was 13.03±1.7 years. There were 25 males and 10 females. The mean age of male patients between Tanner stage 2(14.63±0.52 years) and Tanner stage 3 (14.75±0.5 years) was significantly higher than the Indian data for males (11.3 and 12.8 years, respectively). The mean age of female patients between Tanner stages 2 (13.5±2.12 years) and Tanner stage 3 (14.33±1.16 years) was higher than the Indian reference data for girls (10.2 and 11.6 years respectively). Conclusion: This study concluded that adolescents with SCD were significantly shorter in height and weight than the standard reference population. Sexual maturity is delayed in adolescents with sickle cell anaemia.

Dimethyl Arginine

Background: Sickle cell disease (SCD) consists of a group of hemoglobinopathies in which individuals inherit hemoglobin variants derived from single point mutations. Asymmetric dimethylarginine (ADMA) contributes to limiting Nitric Oxide (NO)  bioavailability in SCD. The aim of the present study was to assess the level of the Asymmetric Dimethyl Arginine in children with sickle cell. Methods: This cohort cross-sectional study was carried out on 60 children which were divided in to 3 equal groups. Group I: SCD children with sickle retinopathy. Group II: SCD children without retinopathy. Group III: healthy control children who were selected from the outpatient clinic. Results: There was a significant increase in ADMA level among participants withSCD. There was a positive significant correlation between ADMA  level and family history as well as the  incidence of hepatomegaly. There was no significant correlation between ADMA level and demographic and laboratory parameters except LDH. Conclusions: The level of ADMA is elevated in children with sickle cell anemia. High plasma ADMA level is a risk for hepatomegaly in children with sickle cell anemia.

Background: This monocentric study conducted at the University Hospital of Essen aims to describe maternal and fetal/neonatal outcomes in sickle cell disease (SCD) documented between 1996 to 2021 (N = 53), reflecting the largest monocentric analysis carried out in Germany. Methods/Results: 46 pregnancies in 22 patients were followed. None of the patients died. In total, 35% (11/31) of pregnancies were preterm. 15 pregnancies in eight patients were conceived on hydroxycarbamide (HC), of which nine had a successful outcome and three were terminated prematurely. There was no difference regarding the rate of spontaneous abortions in patients receiving HC compared to HC-naive patients prior to conception. In patients other than HbS/C disease, pregnancies were complicated by vaso-occlusive crises (VOCs)/acute pain crises (APCs) (96%, 23/24); acute chest syndrome (ACS) (13%, 3/24), transfusion demand (79%, 19/24), urinary tract infections (UTIs) (42%, 10/24) and thromboembolic events (8%, 2/24). In HbS/C patients complications included: VOCs/APCs (43%, 3/7; ACS: 14%, 1/7), transfusion demand (14%, 1/7), and UTIs (14%, 1/7). Independent of preterm deliveries, a significant difference with respect to neonatal growth in favor of neonates from HbS/C mothers was observed. Conclusion: Our data support the results of previous studies, highlighting the high rate of maternal and fetal/neonatal complications in pregnant SCD patients.
