In-Vivo Response of P. Falciparum to Antimalarial Treatment in HIV-Infected and HIV-Uninfected Adults
A Phase 4 study testing sulfadoxine-pyrimethamine in people with Malaria and HIV, run by Centers for Disease Control and Prevention at 1 site in Kenya.
Trial summary
Plasmodium falciparum malaria and HIV are among the most important infectious diseases in sub-Saharan Africa. Approximately two-thirds of the estimated 35 million HIV infected persons live in sub-Saharan Africa. Of the 300-500 million annual cases of malaria infection occurring worldwide, about 90% of P.

About this study
Official title: The in-Vivo Response of P. Falciparum to Antimalarial Treatment in HIV-Infected and HIV-Uninfected Individuals-a 28 Day Efficacy Trial Involving HIV+ and HIV- Adults.
Plasmodium falciparum malaria and HIV are among the most important infectious diseases in sub-Saharan Africa. Approximately two-thirds of the estimated 35 million HIV infected persons live in sub-Saharan Africa. Of the 300-500 million annual cases of malaria infection occurring worldwide, about 90% of P. falciparum infections occur in sub-Saharan Africa, resulting in approximately 1 million deaths, mostly in children under five years of age. It is clear that HIV and malaria are responsible for substantial disease, suffering, and an enormous economic burden on the people who can least afford it. Although a study in 1993 in Tanzania showed significantly higher prevalence of malaria infections in HIV-positive compared to HIV negative adults, until recently there have been few studies showing any association between the two infections.
We conducted a study to measure the efficacy of the then-first line antimalarial drug (sulfadoxine-pyrimethamine) among patients in three study arms: those who were HIV negative, those who were HIV infected with CD4 cell counts < 200, and among HIV infected patients with CD4 cell counts >= 200. Our hypothesis is that patients with HIV infection and low CD4 cell count will not respond to antimalarial therapy as well as patients who are HIV infected with higher CD4 cell counts or who are HIV negative.
Read the detailed description
The study was conducted at Siaya District Hospital, in Nyanza Province, Kenya. Non-pregnant adults who provided consent to participate, who were found to have pure Plasmodium falciparum malaria parasitemia with at least 500 asexual parasites per microliter, and who agreed to undergo HIV counseling and testing were eligible for participation. Clients were then followed with repeat physical examinations and blood smears on day 1,2,3,4,7,14,21 and 28 and any non-scheduled day when they were sick. Those that failed therapy were treated with quinine to clear parasitemia. Samples were also taken to measure reinfection vs. recrudescence, pharmacokinetics, and antifolate resistance markers.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing sulfadoxine-pyrimethamine in people with Malaria and HIV, run by Centers for Disease Control and Prevention at 1 site in Kenya.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Sep 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Kenya. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Drug failure. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2005.
