Original Abstract of the Article

Main Research Findings

Anakinra is a recombinant interleukin-1 (IL-1) receptor antagonist used to treat systemic juvenile idiopathic arthritis (sJIA), refractory Kawasaki disease (KD), and cryopyrin-associated autoinflammatory syndrome (CAPS). Anakinra-associated hepatotoxicity, while rare, has been described in several cases in daily practice. 3 describes three pediatric patients who experienced this side effect in the context of severe macrophage activation syndrome (MAS) in KD and sJIA.

When delivered to the lungs, anakinra showed improved and extended therapeutic efficacy in CF models in vivo, along with higher potency compared to systemic delivery. 4

Anakinra impacted the quality of life of children with colchicine-resistant familial Mediterranean fever (FMF). 26

Anakinra led to improvements in metabolic and inflammatory parameters in participants with both rheumatoid arthritis (RA) and type 2 diabetes (T2D). 18

Reasons for side effects

Side effects of anakinra can occur due to the inhibition of the IL-1 pathway, leading to a suppression of the inflammatory response. IL-1 is a crucial cytokine responsible for triggering inflammatory reactions. Its inhibition can potentially increase the risk of infections or other complications.

Common side effects

Injection Site Reactions

According to 11 , injection site reactions are the most common side effect reported with anakinra administration.

Infections

Anakinra, due to its immunosuppressive effects, can potentially increase the risk of infections. 25 , 1

Hepatotoxicity

Anakinra may rarely cause hepatotoxicity. 3

Neurotoxicity

Anakinra can rarely lead to neurotoxicity. 13

Cytopenia

Anakinra may rarely cause cytopenia. 15

Side effect management

Injection Site Reactions

To minimize injection site reactions, it's recommended to store anakinra in the refrigerator before administration and to apply a cold compress after injection.

Infections

Regular infection screening during anakinra therapy is essential to minimize the risk of infections. If an infection occurs, appropriate treatment is required.

Hepatotoxicity

Regular liver function tests are important during anakinra therapy to minimize the risk of hepatotoxicity. If liver function abnormalities are detected, anakinra administration should be stopped.

Neurotoxicity

Close observation for neurological symptoms during anakinra therapy is important to minimize the risk of neurotoxicity. If any neurotoxic symptoms appear, anakinra administration should be discontinued.

Cytopenia

Regular blood tests are crucial during anakinra therapy to minimize the risk of cytopenia. If cytopenia is observed, anakinra administration should be stopped.

Comparison across studies

Similarities across studies

Several studies have demonstrated the efficacy of anakinra in treating various autoinflammatory diseases. These studies generally suggest that anakinra's side effects are typically mild and often manageable.

Differences across studies

Variations in patient populations, anakinra dosages, and study designs can lead to differences in research findings. For example, 6 suggests that in patients with familial Mediterranean fever (FMF), anakinra dosage may be adjusted or discontinued.

Cautions for real-life application

While anakinra is an effective drug for treating autoinflammatory diseases, it is essential to be aware of the potential for side effects. It's crucial to consult with a doctor before starting anakinra treatment and to fully understand the associated risks and benefits.

Limitations of current research

Many studies on anakinra are relatively small, and further research is necessary. Additionally, data on the long-term safety and efficacy of anakinra when administered for extended periods are lacking.

Future research directions

Further research on anakinra is needed to evaluate its long-term safety and efficacy, determine optimal dosages and administration methods, and elucidate its mechanism of action in greater detail.

Conclusion

Anakinra is a valuable drug for treating autoinflammatory diseases, but the potential for side effects should not be overlooked. Before starting anakinra therapy, consulting a doctor and fully understanding the risks and benefits is vital. We anticipate that future research will provide more information about anakinra's safety and efficacy.
