A Study of Spiramycin in the Treatment of Patients With AIDS-Related Diarrhea

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

To determine the safety and effectiveness of intravenous spiramycin in patients with AIDS-related cryptosporidial diarrhea.

Spiramycin, a macrolide antibiotic, has been studied in the United States for the treatment of cryptosporidial diarrhea. Some reports suggest that spiramycin is useful in improving the symptoms of cryptosporidial diarrhea in some patients. Results of one study, however, showed no significant difference between spiramycin and placebo (inactive medication). A later study indicated that the absorption of spiramycin is significantly decreased when food is present. Thus, the results of the trial may have been due to poor absorption of spiramycin.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria

Concurrent Medication:

Allowed:

Allowed for diarrhea:

• Loperamide hydrochloride capsules (2 mg) or loperamide hydrochloride liquid (1 mg/5 ml).

Allowed for nausea:

• Sucralfate and metoclopramide hydrochloride.

Allowed for vomiting:

• Prochlorperazine and trimethobenzamide hydrochloride.

• Allowed as prophylaxis for Pneumocystis carinii pneumonia (PCP):

• Aerosolized pentamidine.

Patients must have:

• A diagnosis of AIDS according to the CDC.

• Chronic diarrhea.

• Presence of Cryptosporidium oocysts in stool specimen. Patients or a legally authorized representative must sign an informed consent form. Diet will be lactose free, maximum 7 g fat/day with unlimited calorie intake. Patients who require total parenteral nutrition will also be allowed oral intake.
