Brief Summary

Drawing inferences from epidemiologic studies of HIV/AIDS as well well as cell culture and animal studies of HIV inhibition by algae, we propose algal consumption as one unifying characteristic of countries with anomalously low rates. HIV/AIDS incidence and prevalence in Eastern Asia (\<1/10,000 adults in Japan and Korea), compared to Africa (≈1/10 adults) strongly suggest that differences in IV drug use and sexual behavior are insufficient to explain the 1000-fold variation. Even in Africa, AIDS/HIV rates vary. Spirulina is part of the daily diet for many people living in Chad, where prevalence of HIV has remained at less than 4% for more than 20 years. Average daily algae consumption in Asia and Africa ranges between 1 to 2 tablespoons (3 - 13 grams). HIV viral load is the main indicator of infection, however CD4 helper cell counts are most predictive of morbidity and mortality.We hypothesized that the consumption of algae could be important in diminishing the risk of HIV infection, and subsequent progression, possibly by enhancing the immune response.

Outcome Measures

Primary Outcomes (1)

  • Dietary algae influence on CD4 helper cells and HIV viral load

    The first 6 subjects participated for 3 weeks. After analysis of the results, it was determined that there were no side effects and some indication of benefit. The next 6 subjects participated for up to 14 months.

    Once a week for first 3 weeks, then once a month

Secondary Outcomes (1)

  • Would seaweed (Undaria) or spirulina or a combination of the two algae have more benefit?

    Participants were randomized to one of 3 treatments.

Study Arms (1)

Seaweed, Spirulina, Seaweed + Spirulina

EXPERIMENTAL

Randomized to: Arm 1: Seaweed. Ten capsules of .5 grams per capsule for a total of 10 grams per day. Arm 2: Spirulina: Ten capsules of .5 grams per capsule for a total of 10 grams per day. Arm 3: Seaweed: (2.5 grams) plus Spirulina (2.5 grams). Ten capsules of .5 grams per capsule for a total of 10 grams per day.

Other: seaweed, spirulina, seaweed + spirulina

Interventions

Arm 1: Seaweed. Ten capsules of .5 grams per capsule for a total of 10 grams per day. Arm 2: Spirulina: Ten capsules of .5 grams per capsule for a total of 10 grams per day. Arm 3: Seaweed: (2.5 grams) plus Spirulina (2.5 grams). Ten capsules of .5 grams per capsule for a total of 10 grams per day. Spirulina: Ten capsules of .5 grams per capsule for a total of 10 grams per day.

Seaweed, Spirulina, Seaweed + Spirulina
