Active clinical trials for "Cryptosporidiosis"

To examine the efficacy of cow's milk immune globulin in the treatment of diarrhea due to chronic intestinal cryptosporidiosis in patients with AIDS. The secondary end points of the study involve functional improvement which will be determined from nutritional and absorption studies.

To evaluate the safety and efficacy of diclazuril capsules as a treatment for cryptosporidial related diarrhea in AIDS patients who have been treated in the double-blind study # JRD 64,433/1101 and have relapsed, or de-novo patients who have been diagnosed with cryptosporidial related diarrhea and who meet the inclusion and exclusion criteria of this protocol.

This protocol provides for the availability of spiramycin under compassionate-use conditions for the treatment of chronic diarrhea due to cryptosporidium in patients with a compromised immune system, thus deriving additional information regarding its safety and efficacy profile.

To determine the effectiveness of oral paromomycin sulfate for 21 days compared to placebo in the treatment of cryptosporidiosis in patients with HIV infection. To evaluate the safety of oral paromomycin at two different doses. To explore whether paromomycin administered over a longer period provides additional benefit. In previous studies, patients with cryptosporidiosis demonstrated dramatic improvement with paromomycin therapy.

PRIMARY: To assess the effect of bovine anti-Cryptosporidium immunoglobulin (BACI) on the volume of diarrhea due to Cryptosporidium parvum in AIDS patients who have protracted Cryptosporidium enteritis. SECONDARY: To assess changes in stool consistency and frequency, body weight, and safety in this patient population.

To evaluate the safety and efficacy of diclazuril capsules compared with placebo capsules as treatment of cryptosporidial related diarrhea in AIDS patients. Treatment efficacy will be based on the drug's clinical results and on its anti-protozoan effects. Safety will be assessed by the occurrence of side effects as reported by patients at their visits and by frequent monitoring of hematology, biochemistries, and urinalysis.

To determine the pharmacokinetic profile of single doses of letrazuril in patients with AIDS-related cryptosporidial diarrhea; to determine the dose proportionality of single escalating doses of letrazuril; to determine steady-state concentrations of letrazuril; to evaluate the safety and efficacy of escalating doses of letrazuril, compared with placebo, for patients with AIDS-related cryptosporidial diarrhea. Letrazuril, the p-fluor analog of diclazuril, has been shown in an animal model to prevent infections by organisms closely related to the intracellular parasite Cryptosporidium. Reliable data are needed to show the effectiveness of letrazuril in treating AIDS-related cryptosporidial diarrhea.

To provide azithromycin for the treatment of individual patients with proven cryptosporidiosis whose disease has persisted or progressed despite prior therapies.

The purpose of this study is to investigate the incidence of Cryptosporidiosis in Bangladeshi children and describe the acquired immune response to the pathogen as well investigate the potential of human genetic susceptibility.

The aim of the study is to examine the efficacy of ceramic water filters to reduce the burden of waterborne diarrheal illness among infants in selected villages in Kenya. In Kenya very young children are given drinking water or water is used in reconstitution of their food. We hypothesize that ceramic water filters will remove Cryptosporidium from drinking water reducing infection in infants.
