Abstract:
Infectious diseases occur worldwide with great frequency in both adults and children. Both infections and their treatments trigger mitochondrial interactions at multiple levels: (i) incorporation of damaged or mutated proteins to the complexes of the electron transport chain, (ii) mitochondrial genome (depletion, deletions, and point mutations) and mitochondrial dynamics (fusion and fission), (iii) membrane potential, (iv) apoptotic regulation, (v) generation of reactive oxygen species, among others. Such alterations may result in serious adverse clinical events with great impact on children's quality of life, even resulting in death. As such, bacterial agents are frequently associated with loss of mitochondrial membrane potential and cytochrome c release, ultimately leading to mitochondrial apoptosis by activation of caspases-3 and -9. Using Rayyan QCRI software for systematic reviews, we explore the association between mitochondrial alterations and pediatric infections including (i) bacterial: M. tuberculosis, E. cloacae, P. mirabilis, E. coli, S. enterica, S. aureus, S. pneumoniae, N. meningitidis and (ii) parasitic: P. falciparum. We analyze how these pediatric infections and their treatments may lead to mitochondrial deterioration in this especially vulnerable population, with the intention of improving both the understanding of these diseases and their management in clinical practice.
Insights
Infectious diseases harm children by damaging mitochondria, affecting energy production and cell death pathways. Understanding these mitochondrial alterations is key to improving pediatric infection treatment and outcomes.
Area of Science:
- Mitochondrial biology
- Pediatric infectious diseases
- Cellular apoptosis
Background:
- Infectious diseases frequently impact children globally.
- Infections and treatments disrupt mitochondrial function, affecting the electron transport chain, genome, membrane potential, and apoptosis.
- Mitochondrial damage can lead to severe clinical events in children, impacting their quality of life and survival.
Purpose of the Study:
- To explore the association between mitochondrial alterations and pediatric infections.
- To analyze the impact of bacterial and parasitic infections on mitochondrial health in children.
- To improve the understanding and clinical management of pediatric infections by examining mitochondrial damage.
Main Methods:
- Systematic review methodology.
- Utilized Rayyan QCRI software for data analysis.
- Focused on specific bacterial pathogens (M. tuberculosis, E. cloacae, P. mirabilis, E. coli, S. enterica, S. aureus, S. pneumoniae, N. meningitidis) and the parasite P. falciparum.
Main Results:
- Bacterial infections are linked to loss of mitochondrial membrane potential and cytochrome c release.
- These events activate caspase-3 and -9, initiating mitochondrial apoptosis.
- Mitochondrial alterations are a significant consequence of pediatric infections.
Conclusions:
- Mitochondrial dysfunction is a critical factor in the pathogenesis of pediatric infectious diseases.
- Further research into these mechanisms can guide therapeutic strategies.
- Addressing mitochondrial damage is essential for improving pediatric patient care.

The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
