[Role of Mycoplasma infection in pediatric pathology]
Abstract:
The review presents data from the literature showing the variability of manifestations of mycoplasmal infection (M. pneumoniae, M. hominis, T-strain) in childhood. The etiological role of M. pneumoniae (as a monoantigen and in association with respiratory viruses) in acute respiratory infections and pneumonias has been established. M. pneumoniae also plays a certain role in the development of attacks of bronchial asthma and chronic recurrent pneumonias. M. hominis, being an urogenital mycoplasma, may also be the causative agent of acute respiratory infections and pneumonias. A high rate of infection of newborn babies with M. hominis and T-strains is noted. There is evidence indicating frequent and generalized mycoplasmal infection in infants in the perinatal period. In addition to changes in the lungs, mycoplasmal infection produces lesions in the heart, liver, kidneys, central nervous system and other organs, produces the development of hemolytic anemia and thrombocytopenia. Some studies indicate the possibility of intrauterine mycoplasmal infection and its terotogenic effect on the human fetus.
Insights
Mycoplasmal infections in children, caused by M. pneumoniae and M. hominis, manifest diversely, affecting respiratory health and other organs. Early detection and understanding of these infections are crucial for pediatric health outcomes.
Area of Science:
- Pediatric infectious diseases
- Microbiology
- Pulmonology
Context:
- Mycoplasma species, including Mycoplasma pneumoniae, Mycoplasma hominis, and T-strains, are significant pathogens in childhood infections.
- These organisms exhibit a wide range of clinical presentations, from acute respiratory infections and pneumonia to exacerbations of asthma and chronic lung diseases.
- Neonatal and perinatal infections are a growing concern, with high rates of M. hominis and T-strain acquisition in newborns.
Purpose:
- To review and synthesize current literature on the varied clinical manifestations of mycoplasmal infections in pediatric populations.
- To elucidate the etiological roles of specific Mycoplasma species in respiratory illnesses and other systemic complications.
- To highlight the potential for generalized and intrauterine infections, including teratogenic effects.
Summary:
- Mycoplasma pneumoniae is a key cause of acute respiratory infections and pneumonia in children, often in conjunction with other viruses.
- M. pneumoniae also contributes to bronchial asthma attacks and recurrent pneumonias.
- M. hominis and T-strains, typically urogenital, can also cause respiratory infections and are frequently transmitted to newborns, leading to generalized infections in infants.
- Systemic involvement extends beyond the lungs, affecting the heart, liver, kidneys, central nervous system, and leading to hematological disorders like hemolytic anemia and thrombocytopenia.
- Intrauterine transmission and potential teratogenic effects on the fetus are also indicated.
Impact:
- Establishes the significant and diverse role of mycoplasmas in pediatric morbidity.
- Underscores the importance of considering Mycoplasma in the differential diagnosis of various childhood illnesses, including respiratory and systemic conditions.
- Emphasizes the need for further research into diagnosis, treatment, and prevention strategies for mycoplasmal infections in neonates and children.
