January 29, 2009 updated by: National Institute for Medical Research, Tanzania

The Effect of Probiotic Supplementation With Lactobacillus GR-1 and RC-14,on the Immune Status, Diarrhea and Bacterial Vaginosis Cure Rate Among HIV Patients; a Randomised, Placebo Controlled Trial

The purpose of this study is to asses whether probiotics Lactobacillus rhamnosus (GR-1) and reuteri (RC-14) are able to prevent diarrhea, delay the decline of the immune system and prevent and/or cure bacterial vaginosis among HIV patients.

Detailed Description

Background: Two third of all people infected with HIV live in Sub-Saharan Africa. A region also affected with a great burden of other infectious diseases. Relatively few patients have access to anti-retroviral treatment and many suffer from debilitating diarrhea that causes their immune system to deteriorate. Prevention of infectious diseases among HIV patients is of great importance and makes the immune system deteriorate less rapidly. The track record for probiotics to prevent and alleviate infectious diarrhea is impressive. So, the use of probiotics among HIV patients is a logical step and could be an adjunctive tool for physicians to halt the decline of the CD4 count.

Another important application for the use of probiotics is in the treatment of bacterial vaginosis (BV). BV is a vaginal infection, caused by a group of pathogens, which is extremely common, and estimated to occur in 50% of black African women. In the US, the prevalence is 29%, which again is extremely high. This infection makes a woman more vulnerable to contracting sexually transmitted infections, including HIV. Having BV is also a risk factor to transmit HIV to a partner or a newborn. Conventional antibiotic treatment of BV has a cure rate of 40% among black African women. A recent study shows that combining the probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 with an antibiotic has a cure rate of 88%.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
