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.

Exclusion Criteria

Co-existing Condition:

Patients with known sensitivity to macrolide antibiotics are excluded. Consideration must be given to the fact that spiramycin is a macrolide antibiotic and, therefore, may have the potential to induce hepatotoxicity.

• Patients with a compromised immune system may have hepatic abnormalities or even hepatitis. If the benefit-to-risk ratio does not favor the use of spiramycin, the patients must be excluded from the study.

Concurrent Medication:

Excluded:

• Other investigational drugs.
