Original Abstract of the Article

Major research findings

Aldesleukin, recombinant human IL2, is an effective immunotherapy for metastatic melanoma and renal cancer, with durable responses in approximately 10% of patients; however, 5 indicates that severe side effects limit the maximum dose and thus the number of patients who can receive treatment and potential cure. Therefore, there is a need for new methods to reduce side effects and provide treatment to more patients.

3 shows that humanized mice can be used to predict the immunotoxicity of human biologics. Humanized mice can mimic the human immune system, making them a valuable tool for assessing the immunotoxicity of biologics.

Also, 14 describes the development of a fusion protein of GM-CSF and IL-2 that specifically binds to tumor cells. This fusion protein enables the simultaneous delivery of GM-CSF and IL-2 to tumor cells, potentially leading to fewer side effects and greater efficacy than conventional treatments.

Reasons for side effects

The side effects of aldesleukin are thought to be caused by the strong immunostimulatory effects of IL-2, which can cause an excessive reaction in the immune system. 7 states that cytokines are small MW (<30 kDa) key signaling proteins that modulate cellular activities in immunity, infection, inflammation, and malignancy. Understanding their function requires recognizing their pleiotropy and often overlapping and functional redundancies. Aldesleukin belongs to the IL-2 family of cytokines and promotes the growth and activation of immune cells. Therefore, excessive immunostimulatory effects can lead to various side effects.

Common side effects

Fever

15 observed fever when high-dose inhaled interleukin-2 therapy was administered to patients with malignant melanoma with lung metastases. In addition, 12 reported side effects such as fever when patients with metastatic renal cell carcinoma received a combination of dendritic cell vaccine, interleukin-2, and interferon-α2a.

Fatigue

7 states that interleukin-2 can cause side effects such as fatigue.

Nausea and vomiting

7 states that interleukin-2 can cause side effects such as nausea and vomiting.

Diarrhea

7 states that interleukin-2 can cause side effects such as diarrhea.

Rash

7 states that interleukin-2 can cause side effects such as rash.

Dyspnea

15 observed dyspnea when high-dose inhaled interleukin-2 therapy was administered to patients with malignant melanoma with lung metastases.

Heart failure

7 states that interleukin-2 can cause side effects such as heart failure.

Kidney damage

7 states that interleukin-2 can cause side effects such as kidney damage.

Liver damage

7 states that interleukin-2 can cause side effects such as liver damage.

Neurotoxicity

7 states that interleukin-2 can cause side effects such as neurotoxicity.

Immunosuppression

11 states that interleukin-2 can cause immunosuppression.

Thyroid dysfunction

10 states that aldesleukin can cause thyroid dysfunction. Therefore, patients taking aldesleukin should have regular thyroid function tests.

Side effects management

Fever

8 suggests using antipyretics for fever. If the fever is severe, hospitalization may be necessary.

Fatigue

8 states that getting enough rest is important for fatigue. Blood transfusions and IV fluids may also be used if necessary.

Nausea and vomiting

8 suggests using antiemetics for nausea and vomiting.

Diarrhea

8 suggests using antidiarrheal medications for diarrhea. It is also important to stay hydrated to prevent dehydration.

Rash

8 suggests using steroid ointment for rashes. Hospitalization may be necessary in severe cases.

Dyspnea

8 states that oxygen therapy or mechanical ventilation may be required for dyspnea. Hospitalization is necessary in severe cases.

Heart failure

8 suggests using diuretics and vasodilators for heart failure. Hospitalization is necessary in severe cases.

Kidney damage

8 states that hydration and dialysis may be necessary for kidney damage.

Liver damage

8 suggests using steroids and immunosuppressants for liver damage.

Neurotoxicity

8 states that symptomatic treatment is necessary for neurotoxicity. Hospitalization may be necessary in severe cases.

Immunosuppression

8 suggests using antibiotics for immunosuppression.

Thyroid dysfunction

8 states that hormone replacement therapy is required for thyroid dysfunction.

Comparison across studies

Commonalities across studies

These studies indicate that aldesleukin is an effective immunotherapy for cancers such as metastatic melanoma and renal cancer. They also show that aldesleukin can cause side effects such as fever, fatigue, nausea, vomiting, diarrhea, and rash.

Differences across studies

These studies differ in the administration method, dosage, frequency, and severity of side effects of aldesleukin. Therefore, these differences should be considered when evaluating the side effects of aldesleukin.

Points to note regarding real-world applications

Aldesleukin has serious side effects, so it is essential to take it as directed by a doctor. It is also necessary to undergo regular blood tests and organ function tests while taking aldesleukin.

Limitations of current research

Current research provides limited information on the side effects of aldesleukin. Therefore, further research is needed to understand the side effects of aldesleukin in more detail.

Future research directions

Further research is needed on developing new treatments to reduce side effects of aldesleukin and on developing preventive measures to reduce the risk of side effects from aldesleukin.

Conclusion

Aldesleukin is an effective immunotherapy for cancers such as metastatic melanoma and renal cancer, but it has serious side effects, so it is essential to take it as directed by a doctor. Further research is needed on developing new treatments to reduce side effects of aldesleukin and on developing preventive measures to reduce the risk of side effects from aldesleukin.
