Insights

Young children with fever are at higher risk of Plasmodium falciparum hyperparasitaemia, a condition linked to severe malaria. Early identification and management are crucial for better outcomes in endemic regions.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Malariology

Background:

  • Childhood severe malaria frequently presents with hyperparasitaemia.
  • Limited data exists on risk factors for hyperparasitaemia in malarious children.

Purpose of the Study:

  • To evaluate risk factors associated with Plasmodium falciparum hyperparasitaemia in children.
  • To assess the association between hyperparasitaemia and progression to cerebral malaria.

Main Methods:

  • Prospective enrollment of 3338 malarious children between 2008-2010 in southwestern Nigeria.
  • Hyperparasitaemia defined as asexual parasitaemia > 250,000/μl.
  • Multiple regression analysis to identify independent risk factors.

Main Results:

  • Hyperparasitaemia was present in 3% of enrolled children.
  • Independent risk factors included younger age (≤ 11 years), fever, and enrollment after 2008.
  • Hyperparasitaemia significantly increased the risk of progression to cerebral malaria, particularly in children under 5.

Conclusions:

  • Young age and fever are key risk factors for childhood hyperparasitaemia.
  • Hyperparasitaemia is a significant predictor of progression to cerebral malaria.
  • Findings inform malaria control strategies and clinical management in sub-Saharan Africa.

Malaria01:29

Malaria

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...
Symbiosis00:58

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Diversity of Protists II01:27

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
