Nonvitamin, Nonmineral Dietary Supplementation in HIV-Positive People Nutrition in Clinical Practice 22:679-687, December 2007 American Society for Parenteral and Enteral Nutrition
Nonvitamin/Nonmineral (NVNM) • Dietary supplement • Herbs • Botanicals • Concentrates • Metabolites • Constituents • Extracts • Most common • echinacea, gingko biloba
HIV-infected population • ~15% used herbal medicine • Questions to ask… • How the components of these pills will interact with conventional medicine and alter patient care? • How the financial burden of these supplements will affect the patient.
Therapy for HIV/AIDS • Health maintenance • Control of viral replication • Highly active antiretroviral therapy (HAART) • Questions to ask… • Do supplements interfere with HAART metabolism? • What supplements the HIV-infected population is taking? • What is the interaction with HIV medications and disease process?
Objective • Describe current NVNM supplement use of HIV-infection people • Financial burden of buying these supplements • Review current literature on potential interaction between NVNM supplements
Methods • Nutrition for Healthy Living study • Subjects: • Boston area/ Rhode Island • 1995 to 2002 • Documentation of HIV infection • Age >18 years
Data Collection • Data • Medical • Nutrition • Dietary intake • Body composition • Quality of life • Met with a registered dietitian • Educated on keeping a 3-day food record
Study Design • Cross-sectional • Population: • HIV-infected patients in the NFHL study • Duration: • 9/1/2001 to 9/1/2002
Results • 72 subjects out of 368 reported consumption of NVNM supplements • 24% men, 8% women • Caucasian • Education: at least a high school diploma • A mean of 6 NVNM supplements per subject
NVNM supplements • Most common • Glutamine (51%) • N-acetyl-cysteine (36%) • Fish oil (33%) • Alpha-lipoic acid (32%) • Acetyl-L-carnitine (28%) • Coensyme Q10 (28%)
Vitamin/Mineral • Most common • Multivitamin / Multimineral (83%) • Vitamin E (51%) • Vitamin C (47%) • Vitamin B complex (43%) • Calcium (29%) • Selenium (28%)
Discussion • Supplement users • Take an average of 4 VM + 6 NVNM • White • Well-educated • High incomes • Secure housing • Not IV drug users • Receive appropriate HIV/AIDS therapy • Diet • High fiber and protein • More calories from polyunsaturated and monounsaturated fatty acids
Glutamine • Functions • Increased body weight • Increased body cell mass • Increased interacellular water • Provide a highly cost-effective therapy for HIV patients
N-acetyl-cysteine (NAC) • Glutathione precursor • Sulfur containing amino acid • Functions • Restore cysteine and glutathione levels • Inhibit the replication of HIV virus
Fish Oil • Polyunsaturated fatty acid • Eicosapentaenoic acid (EPA) • Docosahexaenoic acid (DHA) • Functions • Lower triglyceride levels • Decrease mortality • Lower blood pressure
Alpha-lipoic acid (ALA) • Vitamin-like antioxidant • Nonessential nutrient • Functions • Treatment of diabetic polyneuropathy • Inhibit the replication of HIV
Acetyl-L-carnitine • Transports long-chain fatty acids across the inner mitochondrial membrane in the form of acetyl carnitine • Functions • Promote energy metablosim • Promote regeneration of nerves • May prevent cell death of CD4 cells
Coenzyme Q10 • Vitamin-like fat-soluble substance • Functions • Produce energy needed for cell growth and maintenance • Antioxidant
Conclusions • NVNM supplement use is common in HIV patients • Estimated cost : $25-40 / week • May involve some risk • Further research is necessary
