Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Hansen's Disease Other: Multi-Drug Therapy (Novartis Ⓡ) Dietary Supplement: Virgin Coconut Oil Phase 1 Phase 2

Detailed Description:

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).

Main Outcome Measures: The mean and inter-quartile range of MDA, SOD, and GSH blood levels; bacterial index (BI) and morphological index (MI) from slit skin-smears; and treatment response based on the clinical response score. Frequency and severity of lepra reactions will also be noted.

Data Analysis: The following statistical tests will be used: Mann-Whitney test to compare the difference between median values of group 1 and group 2; Kruskal-Wallis Test for multiple comparisons; Wilcoxon signed ranks test for comparing differences in median values within groups; Fisher's exact test to compare the frequency of categorical data of treatment response (cutaneous manifestations); and T test for the quantitative data (neurologic manifestations) will be used. Values of p<0.05 will be considered statistically significant.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in Bacterial Indices [ Time Frame: 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. ]
  2. Change in Oxidative Stress Markers [ Time Frame: 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.


Secondary Outcome Measures :
  1. Change in Clinical Response Score (CRS) [ Time Frame: 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. ]
  2. Lepra reactions [ Time Frame: 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. ]

Other Outcome Measures:
  1. Adverse events [ Time Frame: Adverse events will be noted every 4 weeks from initial consult for a total of 24 weeks. ]
  2. Patients' assessment of VCO [ Time Frame: At the 24th week (on final follow-up), the patients in group 2 will be asked to answer the VCO assessment questionnaire. ]
    The following characteristics of VCO will be noted: taste/palatability, smell, ease of ingestion, efficacy, and degree of compliance.
