Chloroquine use improves dengue-related symptoms

Area of Science:

• Medical research
• Infectious diseases
• Clinical pharmacology

Background:

• Dengue is a significant global arboviral disease.
• Chloroquine, an antimalarial, exhibits antiviral properties.
• The efficacy of chloroquine in dengue treatment requires investigation.

Purpose of the Study:

• To evaluate the effect of chloroquine on dengue patients.
• To assess chloroquine's impact on disease duration, fever, and quality of life.

Main Methods:

• A randomized, double-blind, placebo-controlled study.
• 129 patients with dengue-like symptoms received chloroquine or placebo for three days.
• 37 confirmed dengue patients completed the study (19 chloroquine, 18 placebo).

Main Results:

• No significant difference in disease duration or fever metrics between groups.
• 63% of dengue patients on chloroquine reported reduced pain and improved daily function (p=0.0004).
• Symptomatic improvement ceased upon medication discontinuation; effects not seen in non-dengue patients.

Conclusions:

• Chloroquine improved dengue patients' quality of life and daily functioning.
• Chloroquine did not alter dengue's clinical course (duration, fever).
• Further studies are needed to confirm clinical benefits and assess side effects.
