简要总结
To date, there has been no clinical investigation on the effects of virgin coconut oil (VCO) oral supplementation on patients with Hansen's disease (HD) undergoing medical treatment. This study aims to examine the possible protective effect of exogenous supplementation of VCO on the oxidative stress, antioxidant status, and treatment response among HD patients. Treatment response will be defined as the clinical changes in cutaneous and neurologic manifestations as measured by the clinical response score. This study also aims to investigate the potential of VCO as an adjunct to Multi-Drug Therapy (MDT) in mitigating lepra reactions.
详细描述
Objective: To determine the effect of co-administration of virgin coconut oil (VCO) oral supplementation and standard Multi-Drug Therapy (MDT) on malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione (GSH) blood levels and to determine and compare treatment response between leprosy cases treated with MDT alone and cases treated with MDT with VCO supplementation.
Design: This is an open label, controlled clinical trial and a preliminary/phase 1 trial.
Setting: Patients seen in the out-patient clinic of the Section of Dermatology, Philippine General Hospital, a tertiary government hospital.
Participants: Twenty-six previously untreated Hansen's Disease (HD) patients, 18 years old and above, diagnosed clinically and confirmed histologically with HD.
Intervention: The 26 HD patients will be divided into two groups: group 1 will receive only MDT and group 2 will receive MDT with VCO supplementation. Both groups 1 and 2 will consist of 6 or 7 Paucibacillary (PB) patients and 6 or 7 Multibacillary (MB) patients. All participants will have MDA, SOD, and GSH blood levels taken on initial consult and on the third and sixth months. Treatment response will be measured by a clinical response score, which will be graded by a blinded investigator based on cutaneous manifestations (no change, moderate improvement, definite improvement, worse) and neurologic manifestations (no change, improvement, worse).

结局指标
主要结局
Change in Bacterial Indices
时间窗: The Bacterial Index (BI) and Morphologic Index (MI) will be determined from the slit skin smears of the patients on initial consult and at the sixth month of treatment.
Change in Oxidative Stress Markers
时间窗: The oxidative stress markers will be measured in blood on initial consult, on the third month, and at the sixth month of treatment.
The oxidative stress markers consist of Malondialdehyde (MDA), Superoxide Dismutase (SOD), and Glutathione (GSH) levels.
次要结局
- Lepra reactions(The frequency of lepra reactions (type 1 or type 2) will be noted throughout the study period of 24 weeks. The severity of these reactions will be graded.)
- Change in Clinical Response Score (CRS)(A blinded outcome assessor will take the CRS for changes in the skin and nerves on initial consult and every 4 weeks after over the study period of 24 weeks.)
