Treatment Approaches for Dengue Fever

Symptomatic and Supportive Care

Dengue fever, a mosquito-borne viral disease, primarily requires symptomatic and supportive treatment. This approach is the mainstay of dengue management, focusing on alleviating symptoms and preventing complications. Key strategies include maintaining fluid balance through oral or intravenous rehydration and using analgesics to manage pain and fever . In severe cases, such as dengue hemorrhagic fever or dengue shock syndrome, intensive medical care, including blood transfusions and intravenous fluids, is necessary to manage bleeding and maintain blood pressure .

Integration of Traditional Chinese Medicine (TCM) and Western Medicine

Recent studies have explored the integration of Traditional Chinese Medicine (TCM) with conventional Western therapies. This combined approach has shown promise in improving patient outcomes. For instance, patients treated with both TCM and Western medicine experienced significant symptom resolution and were discharged without severe complications. Common TCM treatments included herbal formulas like Zhu Ye Shi Gao Tang and Gui Pi Tang, which were effective in managing symptoms such as fever and muscle ache.

Antiviral Agents

Despite extensive research, no specific antiviral drugs have been conclusively proven effective against dengue fever. The α-glucosidase inhibitor celgosivir was tested in a randomized, double-blind, placebo-controlled trial but did not significantly reduce viral load or fever burden. Similarly, the nucleoside analogue riamilovir showed some promise in a case report from Guinea, but broader clinical efficacy remains unproven. The search for effective antiviral treatments continues, with ongoing studies targeting viral proteins like NS3 and NS5.

Herbal Remedies and Phytochemicals

Herbal remedies, particularly those derived from Carica papaya L. leaves, have been traditionally used to treat dengue fever. These remedies are believed to help prevent thrombocytopenia (a dangerous drop in platelet count) and boost immunity. Although widely used in some regions, such as Malaysia, their efficacy is still debated among medical professionals. Additionally, various phytochemicals have shown potential in inhibiting dengue virus in laboratory settings, suggesting a rich source of future therapeutic agents.

Vaccination and Preventive Measures

Preventive measures, including vaccination, are crucial in managing dengue fever. The Dengvaxia vaccine is currently the only licensed vaccine and is used in some South American countries. However, its approval is limited, and it is not widely accepted globally. Preventing mosquito bites through the use of insect repellents, protective clothing, and eliminating mosquito breeding sites remains a primary strategy in controlling the spread of dengue.

Conclusion

The treatment of dengue fever primarily involves supportive care to manage symptoms and prevent complications. Integrating TCM with Western medicine shows potential benefits, while the search for effective antiviral drugs continues. Herbal remedies and phytochemicals offer promising avenues for future research. Preventive measures, including vaccination and mosquito control, are essential in reducing the incidence and impact of dengue fever.
