[Neonatal healthcare associated-infections in the Maghreb. A systematic review and meta-analysis]. / Infections associées aux soins en néonatalogie dans la région du grand Maghreb. Revue systématique et méta-analyse.

BACKGROUND: Healthcare-associated infections are a major source of morbidity and mortality in neonatology. Our aim was to describe the epidemiology of Healthcare-associated infections in neonatology (frequency, associated factors and prognosis). METHODS: Articles were searched in the PubMed, Scopus and Web of Science databases. We included observational studies describing prevalence, incidence or mortality among new-born babies having developed infections more than 48hours after hospitalization. The pooled prevalence, incidence and mortality estimates were analysed using the random effects model. Publication bias was analysed using the funnel plot and Egger's test statistics. Data analysis was carried out using R Studio software v1.2. RESULTS: Among the initially identified 137 studies, ten articles fulfilled the inclusion criteria and were included in the metanalysis. They mainly concerned Morocco, Tunisia and Algeria. Pooled incidence was 10% (95% CI [4%-18%]) and overall mortality was 49% (95% CI [33%-66%]). Heterogeneity between studies was significantly high, with rates of 98% and 90% respectively. CONCLUSION: This review underlined a need to undertake more large-scale multicentric surveys and studies on monitoring systems and the attitudes and practices of relevant caregivers, the objective being to better understand the realities of healthcare-associated infections in Greater Maghreb neonatology units.

Magnitude of prematurity in the countries of the Great Maghreb.

BACKGROUND: Prematurity is the leading cause of death in neonates, accounting for 75% of neonatal mortality, and the second leading cause of death among children under 5 years of age. OBJECTIVE: To study the extent of prematurity in the Great Maghreb, concerning its various aspects: frequency, risk factors and complications. METHOD: We conducted a systematic review of the literature by searching for all data from the Greater Maghreb related to prematurity published between 2000 and 2018. The search strategy relied on the Medline and Google Scholar databases. Prematurity is defined as any birth occurring at a gestational age less than 37 weeks of amenorrhea. RESULTS: In the Maghreb, the prevalence of prematurity ranged from 6.7% to 15.4%. The main risk factors were infections and chronic maternal conditions, extreme maternal ages and adverse socio-economic conditions. The mortality rate among premature infants ranged from 28% to 45%. Short-term complications were dominated by respiratory and metabolic disorders and infections. CONCLUSION: In view of the serious complications and high mortality caused by prematurity, prevention strategies must be put in place. These should be based on the development of pregnancy surveillance programs, the fight against precariousness and the upgrading of neonatal care structures.

Non-adherence to antiretroviral therapy in patients infected with HIV and cryptococcal meningitis: two cases at the Lambaréné Hospital Center in Gabon.

Cryptococcal meningitis is a serious infection occurring mainly in immunodepressed patients, especially those with AIDS. Its incidence is growing among people living with HIV/AIDS who interrupt their antiretroviral treatment. We report two cases that occurred in this situation and had lethal outcomes in the short term. Testing for cryptococcal antigen in serum (serum CRAG test) enables a reliable and early diagnosis, and its use should be promoted in rural areas of sub-Saharan Africa.

Decrease of microscopic Plasmodium falciparum infection prevalence during pregnancy following IPTp-SP implementation in urban cities of Gabon.

BACKGROUND: Six years after the implementation of intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) in Gabon, its impact on placental malaria and pregnancy outcomes remains unknown. METHODS: Age, gestational data, use of IPTp-SP and birth weight were recorded during a hospital-based cross-sectional survey performed in 2011 in 387 women at the end of pregnancy. RESULTS: Malaria prevalence was 6.7 and 5.3% in peripheral and placental blood respectively. Overall, 59.0% women took at least two IPTp-SP doses which was associated with 50% reduction of Plasmodium; (P.) falciparum infection in primigravidae. Previous malaria treatment was a risk factor for peripheral P. falciparum infection, while uptake of IPTp-SP was associated with reduced parasitaemia. Anaemia prevalence was 38.0%, low birth weight and prematurity rates were 6.0 and 12.0% respectively. Young age was associated with a higher frequency of malaria, anaemia, low birth weight and preterm delivery (p<0.01). Birth weight significantly rose with increasing age (p<0.01), parity (p=0.03) and number of SP doses (p=0.03). A birth weight reduction of 230 g in case of peripheral parasitaemia (p=0.02) and of 210 g with placental parasitaemia (p=0.13) was observed. CONCLUSIONS: Microscopic P. falciparum prevalence during pregnancy significantly declined between 2005 and 2011, following IPTp-SP implementation in Gabon. Young women and paucigravidae remain the most susceptible to malaria and associated outcomes.
