Crise vaso-occlusive drépanocytaire sévère: aspects cliniques, étiologiques et thérapeutiques au CHU Sylvanus Olympio de Lomé / Clinical, aetiological and therapeutic features of severe sickle cell related vaso-occlusive crisis at the Sylvanus Olympio University Hospital, Lomé

Introduction: la crise vaso-occlusive (CVO) est la plus fréquente manifestation de la drépanocytose et la première cause d´hospitalisation des enfants atteints. L´objectif de cette étude est de décrire les aspects cliniques des CVO sévères, de déterminer les étiologies des syndromes infectieux qui les accompagnent et de décrire leur prise en charge. Méthodes: il s'agit d'une étude transversale descriptive portant sur 137 drépanocytaires majeurs hospitalisés pour CVO sévères du 1er janvier 2009 au 31 décembre 2011 dans le service de pédiatrie du CHU Sylvanus Olympio. Résultats: les drépanocytaires homozygotes SS étaient les plus nombreux (n=98; 71,5%), suivis des doubles hétérozygotes SC (n=28; 20,5). Le délai moyen de consultation était de 4,7 ± 4,4 jours. Le traitement avant l´admission comportait des antibiotiques (28,5%). Les CVO étaient surtout ostéo-articulaires (70,8%). Dans 98,5% des cas, une infection bactérienne associée a été confirmée (48,9%) ou présumée (49,6%). Les principales étiologies étaient le syndrome thoracique aigu (26,3%), l´ostéomyélite aiguë (10,9%), l´infection urinaire (6,6%), la septicémie (3,6%). Un germe a été isolé chez 14,6% des patients, Escherichia coli (30%) étaient en tête suivi de Klebsiella pneumoniae (25%), Staphylococcus aureus (15%), Salmonella typhi (10%), Streptococcus pneumoniae (5%), le Streptocoque D (5%), l´Enterobacter (5%) et l´Acinetobacter (5%). Le taux de mortalité était de 2,2%. La durée moyenne d´hospitalisation était de 11,4 ± 8,8 jours. Conclusion: les CVO drépanocytaires sévères sont en majorité associées aux infections bactériennes en milieu tropical. Une antibiothérapie adaptée et précoce constitue le moyen thérapeutique indispensable pour prévenir ou traiter ces patients.

Introduction: vaso-occlusive crisis (VOC) is the most common manifestation of sickle cell disease and the leading cause of hospitalization among affected children. The purpose of this study is to describe the clinical features of severe VOCs, to determine the etiologies of infectious syndromes that accompany them and to describe their management. Methods: we conducted a descriptive cross-sectional study of 137 adult patients with sickle cell disease hospitalised for severe VOC in the Paediatric Department of the Sylvanus Olympio University Hospital from 1 January 2009 to 31 December 2011. Results: the majority of patients (n=98; 71.5%) had homozygous sickle cell (SS), followed by double heterozygous SC disease (n=28; 20.5). The median of consultation time was 4.7 ± 4.4 days. Treatment before admission was based on antibiotics (28.5%). VOCs were mainly osteoarticular (70.8%). In 98.5% of cases, an associated bacterial infection was confirmed (48.9%) or suspected (49.6%). The main etiologies included acute chest syndrome (26.3%), acute osteomyelitis (10.9%), urinary tract infection (6.6%) and septicaemia (3.6%). One germ was isolated from 14.6% of patients: Escherichia coli (30%), followed by Klebsiella pneumoniae (25%), Staphylococcus aureus (15%), Salmonella typhi (10%), Streptococcus pneumoniae (5%), Streptococcus D (5%), Enterobacter (5%) and Acinetobacter (5%). Mortality rate was 2.2%. The average length of stay in hospital was 11.4 ± 8.8 days. Conclusion: severe sickle cell related vaso-occlusive crisis is mainly associated with bacterial infections in tropical environments. Appropriate and early antibiotic therapy is the essential therapeutic means to prevent or treat these patients.

Predictors of early-onset neonatal sepsis in premature newborns: Case-control study.

INTRODUCTION: Early-onset neonatal sepsis (EOS) is difficult to diagnose clinically because the semiology of premature newborns is poor during the first days of life. This study aimed to identify predictive factors of EOS in neonates less than 37 weeks' gestational age in neonatal care at Louis Mourier Hospital, France. METHOD: This was a case-control study of all newborns less than 37 weeks of gestational age diagnosed and managed for EOS from January 1 to December 31, 2019. The main parameters studied were demographic characteristics, risk factors, laboratory, and bacteriological characteristics. At the benchmarking level, the statistical tests used were the McNemar test for qualitative variables and the paired Student's t-test for quantitative variables. RESULTS: A total of 50 mother-child pairs were included in this study (25 cases and 25 matched controls). The results showed a statistically significant relationship between the birth of a child with EOS and between a premature rupture of membranes of > 18 h (68% of cases vs. 36% of controls; p = 0.042); a positive culture of the placenta (p = 0.0002); C-reactive protein levels of > 6 mg/L (88% of cases vs. 20% of controls; p = 0.001); a procalcitonin level of > 0.6 ng/mL (72% of cases vs. 16% of controls; p = 0.001). Gram-negative bacteria including Escherichia coli (44.5%) and Haemophilus influenzae (14.8%) were the most common pathogens found. CONCLUSION: The search for risk factors must be systematic and the clinic must remain at the center of the diagnostic approach.

Maternal and neonatal complications of childbirth among adolescents at the Sylvanus Olympio University Hospital Centre (CHU-SO), Lomé

Objective: To determine maternal and neonatal complications occurring at childbirth among adolescents.Materials and methods: This is a retrospective, descriptive study conducted from 1st July to 31st December 2019 at the maternity ward of the Sylvanus Olympio University Hospital Centre (CHU- SO), Lomé, Togo. The socio- demographic parameters of the mothers, details of prenatal and perinatal events and the clinical profile of the newborns at birth were studied. Results: The records of 332 adolescent mothers were studied. The average age of the mothers was 17.4 ± 1.5 years, with a range of 13-19 years. The pregnancies in two-thirds (66.3%) were supervised in centres without surgical facilities and by midwives in 83.1% of cases. A little over half of the mothers (53.3%) attended at least four antenatal clinic sessions, while 3.6% attended none. The modes of delivery were spontaneous vaginal (62.3%) and Caesarean section (35.2%). Complications of pregnancy were recorded in 12.9% of the mothers. There were statistically significant associations between the referred status of the mothers and haemorrhages, retained placenta and sepsis (p = 0.001, 0.038 and 0.011, respectively). There were no maternal deaths. The newborn babies required resuscitation in 6.3% of cases, while 7.0% were stillborn.There was a statistically significant relationship between the referred status of mothers and the occurrence of perinatal deaths (p =0.0001). Conclusion: Adolescent mothers are at risk of complications during childbirth, and these risks are increased by poor antenatal care and attempted deliveries in centres without surgical facilities.

Knowledge, attitude and practice of the mothers with anemia of children under five years old in the peadiatric department at Sylvanus Olympio teaching hospital in Lomé.

BACKGROUND: Anemia remains a major cause of morbidity and mortality of children in Togo despite of prevention effort, due to the parents lack of implication. AIM: To determine the knowledges, attitudes and practices of mothers, with anemia ofchildren under five years old Methods : Knowledge Attitudes and Practice survey from the first of february to 31 ofmarch 2012, about an interview of a hundred mothers with children under 5, randomly selected in the consultation, vaccination waiting rooms and in the hospitalisation. RESULTS: Forty mothers had never heard about anemia. Health personnel was the main source of mother's information (29%), mass media represented 8% of mothers information source (radio 5%; television 3%). The decreased of blood in the body is the most given definition from the mothers (44%). Malaria (24%) and malnutrition (19%) were the main causes cited by mothers. Iron deficiency has been mentioned by 3% of the mothers. Palmar - plantar pallor (32%) was the clinical signe the best known by the mothers. Most of the mothers (90%) had never assist to an information education and communication message about anemia prevention. When their children had anemia, 25 mothers (65,8%) took their children to the health center, five mothers (13,2%) had given tomatoes. The use of iron in prophylactic treatment was known by 43% of the mothers. The blend tomatoes and milk was the prophylactic treatment mentioned by 3% of the mothers. Most of the mothers (77%) would advice a mother with a children suffering from anemia to take him to the hospital. The knowledge of anemia by the mothers was correlated to then level of instruction. But the knowledge of prevention did not depend on the instruction level. CONCLUSION: anemia is not well known by the mothers of under five children. It's causes, it's treatment are not well known. Mass media are not very implicated on the subject. The reduction of it's frequency goes by information education and communication activities.
