Study summary

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.

Read the detailed description

Forty patients are randomized to receive either BACI or placebo (bovine colostrum from non-immunized cattle) for 1 week. The double-blind portion of the study will be followed by an open-label phase in which all 40 patients receive BACI for 1 week.

  • Zidovudine (AZT), dideoxyinosine (ddI), dideoxycytidine (ddC), or alternative therapy (provided dose was stable for at least 4 weeks prior to study entry).

Patients must have:

  • AIDS.
  • Cryptosporidium parvum enteritis.
  • Chronic diarrhea.
  • of at least 4 weeks.
  • Ability to tolerate food by mouth.

Exclusion criteria

Exclusion Criteria

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

  • Concurrent unresolved clinical infections with enteric pathogens other than C. parvum (e.g., rotavirus, Salmonella, Shigella, Campylobacter, Giardia, C. difficile toxin, Yersinia, amebiasis, MAI, CMV, Microsporida) as determined by history or routine microbiology screening.
  • Other acute infections or concurrent immediately life-threatening medical crisis other than cryptosporidiosis.
  • Grossly bloody diarrhea.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
