A Multicenter Study of Oral Versus Intravenous Hydration in AIDS Patients With CMV Retinitis Treated With Foscavir (Foscarnet Sodium)

Patients are randomized to receive oral hydration versus intravenous hydration therapy during concomitant intermittent intravenous Foscavir therapy for treatment of cytomegalovirus (CMV) retinitis. Treatment continues during 2 or 3 weeks of induction Foscavir therapy.

Inclusion criteria

Patients must have:

• Documented HIV infection.
• Recent diagnosis of CMV retinitis, by ophthalmoscopic appearance, that requires induction therapy.
• No corneal, lens, or vitreous opacification that precludes examination of the fundi.
• No evidence of other end organ CMV infection.
• No evidence of tuberculous, diabetic, or hypertensive retinopathy.

Exclusion criteria

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

• Clinically significant cardiac, pulmonary, neurologic, gastrointestinal or renal impairment that would prevent adequate voluntary oral hydration (e.g., intubation, coma, status post-gastrectomy, colon resection, gastrointestinal tumors, malabsorption, chronic diarrhea) OR with which hydration would be hazardous (e.g., congestive heart failure).
• Known allergy to foscarnet or related compounds.
• Considered noncompliant or unreliable for study participation.

Concurrent Medication:

Excluded:

• Any investigational drug.
• Potentially nephrotoxic drugs (e.g., amphotericin B, aminoglycosides, cisplatin).

Prior Medication:

Excluded:

• Any investigational drug within 28 days prior to study entry.
• Potentially nephrotoxic drugs (e.g., amphotericin B, aminoglycosides, cisplatin) within 7 days prior to study entry.
