The goal of this clinical trial is to evaluate whether Carica papaya leaf extract (CPLE) can improve platelet counts in children aged 2 to 12 years diagnosed with dengue fever and thrombocytopenia. The main questions it aims to answer are: Does Carica papaya leaf extract significantly increase platelet counts compared to standard supportive therapy alone? Does the use of Carica papaya leaf extract reduce the need for platelet transfusion or PICU admission? Researchers will compare the group receiving CPLE plus standard therapy to the group receiving standard therapy alone to see if CPLE leads to improved platelet recovery and better clinical outcomes. Participants will: Be randomly assigned to receive either standard care or standard care plus Carica papaya leaf extract syrup (10 mL orally, three times daily for 3 days) Undergo blood testing on Day 1 and Day 3 to assess platelet count, hemoglobin, WBC, and packed cell volume Be monitored for clinical outcomes including need for transfusion and admission to the Pediatric Intensive Care Unit (PICU)

Dengue fever is a mosquito-borne viral illness that continues to pose a significant health threat in tropical and subtropical regions, including Pakistan. One of the common hematological complications of dengue infection is thrombocytopenia (a low platelet count), which can lead to bleeding, requiring hospitalization, intensive care, or platelet transfusions. Currently, there is no specific antiviral treatment for dengue; management remains largely supportive. Carica papaya leaf extract (CPLE) has shown potential as an adjunct therapy due to its proposed thrombopoietic, anti-inflammatory, and antiviral properties. Previous studies, primarily conducted in other countries, have suggested that CPLE may aid in increasing platelet counts in patients with dengue fever. However, limited data exists regarding its efficacy in pediatric populations within Pakistan. This randomized controlled trial will be conducted to evaluate the efficacy of oral Carica papaya leaf extract in improving platelet counts in children with dengue-associated thrombocytopenia. The study will be carried out at the Department of Pediatrics, Ziauddin Hospital, Clifton Campus, Karachi, over a period of three months. Participants will be randomly assigned into two groups: Intervention group (n=55): Will receive 10 mL of Carica papaya leaf extract syrup orally three times daily (each 10 mL dose containing 1000 mg of extract) along with standard supportive therapy. Control group (n=52): Will receive standard supportive therapy alone. The primary objective of the study is to assess whether CPLE significantly increases platelet counts from Day 1 to Day 3 compared to standard therapy alone. Secondary objectives include evaluating changes in hemoglobin levels, white blood cell (WBC) count, packed cell volume (PCV), need for platelet transfusion, and admissions to the Pediatric Intensive Care Unit (PICU). Baseline demographics (age, gender, height, and weight) will be recorded. Laboratory tests including complete blood count will be conducted on Day 1 and Day 3. Data will be analyzed to determine whether CPLE leads to meaningful clinical improvements beyond standard care. This study is expected to contribute important local data regarding the use of CPLE in pediatric dengue cases. If effective, this herbal adjunct could offer a low-cost, accessible therapeutic option. However, if no benefit is observed, the findings will help guide clinical practice away from potentially unnecessary interventions.
