Type 2 diabetes is common in ethnic and, minority groups in developing and developed countries such as Africans, African Americans, Asians, Native Americans, Hispano-Latinos and Alaskan indians. A randomized controlled study to assess the efficacy of fermented papaya preparation and green tea infusates in latent diabetes (individuals newly diagnosed as diabetics) is proposed. Glycation products from excess glucose autooxidation can chemically modify DNA causing mutations and cause complex DNA rearrangements. Advanced glycation end-products which play a role as proinflammatory mediators in gestational diabetes can accelerate vascular occlusion by quenching the vasodilating agent nitric oxide. Interaction with high-affinity receptors located on monocytes and macrophages can enhance the production of free radicals and reactive oxygen/nitrogen species, the secretion of tumor necrosis factor-α, interleukin-1 and insulin-like growth factor I which can proliferate endothelial, mesangial and smooth muscle cells and hence contribute significantly to the pathogenesis of cardiovascular complications. The clinical markers include C-reactive proteins (inflammation indicators), protein C (markers of reno vascular injury), uric acid, natriuretic peptides, and the integrity of isolated adipocytes, glucose levels, lipid indices (triglycerides, total cholesterol, VLDL, HDL and LDL). Given that decreased functional activity of activated protein C affects the permeability of the glomerular capillary wall and enhances apoptosis of glomerular endothelial cells and adipodocytes, this has relevance to the pathophysiology of diabetic nephropathy. A second phase of the study is expected to commence after the first 16 weeks in order to assess the ability of the dietary factors to modulate atheroma formation and the integrity of drug therapy (upon commencement of treatment)on the prognosis of diabetes. This will be expected to last up to 3 years.

| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Primary | Assess the effects of green tea and FPP on the levels of C-reactive proteins | The pathophysiology of atherosclerosis and other cardiovascular events have associated inflammatory processes. The levels of plasma high-sensitivity (hs) C-Reactive Protein, an acute phase reactant produced in the liver, known to rise in inflammatory reactions are widely suggested to be a predictor of coronary events; and increased uric acid levels (hyperuricemia) are considered to be a risk factor in many clinical conditions including hypertension, cardiovascular events, diabetes mellitus, stroke, and metabolic syndrome. | 3 months | No |
| Secondary | Assess the effect of green tea and fermented papaya preparation on development of atheroma and drug therapy outcomes | Carotid artery angioplasty and stenting has been proposed as an alternative therapy for patients requiring treatment of carotid artery stenosis as opposed to the "gold standard" surgical intervention, carotid endarterectomy. The second phase of the study will investigate the possible role of green tea and fermented papaya preparation in modulating the risk of stroke by assessing the extent of atheroma using both echocardiography and CT angiography. Patients will be on medication and the therapeutic outcome will be assessed. | 3 years | No |
