Insights
Children with sickle cell disease (SCD) face a higher risk of bacterial meningitis (BM) and worse outcomes, including increased mortality and longer hospital stays. This highlights the critical need for targeted interventions and awareness in affected populations.
Area of Science:
- Pediatrics
- Infectious Diseases
- Hematology
Background:
- Sickle cell disease (SCD) is a genetic blood disorder with significant health implications.
- Bacterial meningitis (BM) is a serious infection of the membranes surrounding the brain and spinal cord.
- Understanding the interplay between SCD and BM is crucial for improving patient outcomes.
Purpose of the Study:
- To investigate the prevalence of SCD in children diagnosed with BM in Luanda.
- To compare the clinical characteristics and outcomes of BM in children with and without SCD.
- To identify risk factors and specific pathogens associated with BM in SCD patients.
Main Methods:
- Retrospective analysis of pediatric patients diagnosed with BM in Luanda.
- Comparison of SCD prevalence in BM patients versus the general population.
- Analysis of inflammatory markers, causative pathogens, mortality rates, and hospital stay duration.
Main Results:
- SCD was diagnosed in 10% of pediatric BM cases, a fivefold increase compared to the general population.
- BM children with SCD exhibited higher inflammatory markers.
- Pneumococcal meningitis was more frequent in BM children with SCD (71% vs. 39%), with higher mortality (39% vs. 22%) and longer hospital stays (15 vs. 11 days).
Conclusions:
- Sickle cell disease is a significant risk factor for bacterial meningitis in children in Luanda.
- Children with SCD experiencing BM have more severe disease, higher rates of pneumococcal meningitis, and poorer outcomes.
- These findings underscore the importance of early diagnosis, targeted prevention strategies, and specialized care for pediatric SCD patients at risk for BM.
Abstract:
Sickle cell disease (SCD) was found in 10% of children with bacterial meningitis (BM) in Luanda, 5-fold more than in the general population. BM children with SCD versus BM children without SCD had higher inflammatory markers, more often had pneumococcal meningitis (71% vs. 39%), and either died (39% vs. 22%) or had a longer hospital stay (15 vs. 11 days).

01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:29Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
