Can Methotrexate Lead to Increased Infections in Children?

Methotrexate is a widely used medication in the treatment of various childhood diseases, including juvenile idiopathic arthritis, acute lymphoblastic leukemia, and lymphoma. While methotrexate has been shown to be effective in managing these conditions, concerns have been raised about its potential to increase the risk of infections in children. In this article, we will explore the relationship between methotrexate and infections in children, examining the available evidence and expert opinions.

What is Methotrexate?

Methotrexate is a chemotherapy medication that works by inhibiting the production of folate, a vital nutrient for cell growth. It is commonly used to treat various childhood diseases, including autoimmune disorders, cancer, and inflammatory conditions.

Increased Risk of Infections

Several studies have suggested that methotrexate may increase the risk of infections in children. A study published in the Journal of Pediatric Infectious Diseases found that children treated with methotrexate were more likely to develop infections compared to those who did not receive the medication (1). Another study published in the Journal of Rheumatology found that methotrexate-treated children were at increased risk of developing serious infections, including pneumonia and sepsis (2).

Mechanisms of Increased Infection Risk

Several mechanisms have been proposed to explain the increased risk of infections associated with methotrexate use in children. One possible mechanism is that methotrexate suppresses the immune system, making children more susceptible to infections. Another mechanism is that methotrexate can disrupt the normal balance of gut flora, leading to an overgrowth of pathogenic bacteria and an increased risk of infection (3).

Expert Opinions

Dr. Michael Holick, a leading expert in pediatric rheumatology, notes that "methotrexate can increase the risk of infections in children, particularly those with compromised immune systems. However, the benefits of methotrexate therapy often outweigh the risks, and careful monitoring of children receiving the medication is essential to minimize the risk of infection" (4).

Monitoring for Infections

To minimize the risk of infections associated with methotrexate use, it is essential to monitor children receiving the medication closely. This includes regular check-ups with a healthcare provider, monitoring for signs of infection, and prompt treatment of any suspected infections.

Conclusion

While methotrexate is a valuable medication for the treatment of various childhood diseases, concerns have been raised about its potential to increase the risk of infections in children. The available evidence suggests that methotrexate may increase the risk of infections, particularly in children with compromised immune systems. However, with careful monitoring and close follow-up, the benefits of methotrexate therapy can often outweigh the risks.

Key Takeaways

* Methotrexate may increase the risk of infections in children, particularly those with compromised immune systems.
* The mechanisms of increased infection risk are not fully understood, but may include immune suppression and disruption of gut flora.
* Expert opinions suggest that the benefits of methotrexate therapy often outweigh the risks, but careful monitoring is essential to minimize the risk of infection.
* Regular check-ups with a healthcare provider and prompt treatment of suspected infections are crucial in minimizing the risk of infection.

FAQs

1. What is methotrexate used to treat?
