Condition diabetes
Treatment fermented papaya preparation (fpp)
Sponsor Ohio State University
Collaborator Osato Research Institute
Start date May 2012

Trial size 25 participants
Trial identifier NCT01618045, 20120293

Summary

Fermented Papaya Preparation (FPP) is a sweet and granular substance available over the counter. FPP possesses antioxidant properties, which provide benefit against age-related complications, and is also known to protect red blood cells (RBCs) against oxidative damage and to help protect against severe forms of thalassemia. The investigators recently showed that ex vivo supplementation of FPP can correct respiratory burst performance of diabetic peripheral blood mononuclear cells (PBMC) via a Sp-1 dependant pathway. Based on these observations, the investigators propose to study the outcome that FPP supplementation has in patients with diabetes.

Eligibility Criteria

Male or female participants from 30 years up to 80 years old.

Inclusion Criteria: - Adult patients 30 to 80 years old with clinically defined type II diabetes and HbA1c ≤ 9.0 and BMI between 22 and 42 - Diabetic subjects selected for the study will meet one or more of the following criteria as recommended by American Diabetes Association: - 1) Symptoms of diabetes and casual plasma glucose 200 mg/dl (11.1 mmol/l) (casual is defined as any time of day without regard to time since last meal. The classic symptoms of diabetes include polyuria, polydipsia, and unexplained weight loss); OR - 2) Fasting plasma glucose (FPG) 126 mg/dl (7.0 mmol/l) (fasting is defined as no caloric intake for at least 8 h); OR - 3) 2-hr plasma glucose 200 mg/dl (11.1 mmol/l) during an oral glucose tolerance test (OGTT) (this test should be performed as described by the World Health Organization, using a glucose load containing the equivalent of 75g anhydrous glucose dissolved in water) Exclusion Criteria: - Individuals who are deemed unable to understand the procedures, risks and benefits of the study (i.e., informed consent) will be excluded - T2DM with HbA1c = 9.1 or above - BMI less than 22 and over 42 - Clinically significant kidney or liver disease - Severe neurologic dysfunction - Females who are pregnant as well as individuals who are therapeutically immuno-compromised will also be excluded in order to minimize the risk to such individuals (and fetus) and to decrease statistical variability and to minimize the potential of confounders - Candidates for inclusion into the study will not include individuals as defined in 45 CFR 46 Subparts B, C and D, nor from any other population which may be considered vulnerable - Pregnant women are excluded to minimize the risk to such individuals (and fetus) and to decrease statistical variability and to minimize the potential of confounders

Description Fermented Papaya Preparation (FPP) possesses antioxidant properties, which provide benefit against age-related complications. FPP is also known to protect red blood cells (RBCs) against oxidative damage and to help protect against severe forms of thalassemia. Several independent observations convergently point toward the hypothesis that treatment with papaya preparations may facilitate wound healing responses. Chronic wounds in patients with diabetes represent a major public health problem. Previous studies from the investigators have demonstrated that wound-site macrophages from patients with diabetes are compromised in their ability to support wound healing. Recently, our laboratory reported the first evidence demonstrating that FPP may improve diabetic wound outcomes by specifically influencing the response of wound-site macrophages and the subsequent angiogenic response. FPP has a long track record of safe human consumption. The objective of the current study is to determine whether FPP is able to improve inducible respiratory burst outcomes in peripheral blood mononuclear cells (PBMC) of participants with diabetes. Our investigators have recently reported that supplementation with standardized fermented papaya preparation (FPP) in adult diabetic mice improves dermal wound healing outcomes. The production of reactive oxygen species (ROS) by type 2 diabetics (T2DM) PBMC is markedly inhibited compared to that of the PBMC from non-diabetic donors. We observed that ex vivo FPP supplementation corrected such inhibition in ROS production by PBMC from T2DM donors. Therefore, based on these observations, the investigators propose to study the outcome that FPP supplementation has in patients with diabetes.
