#RETINITIS DEFINITION TRIAL#

In patients receiving IV cidofovir, analysis of blood urea nitrogen and creatinine levels and urinalysis should be performed before each infusion. The risk of severe renal injury from IV cidofovir can be reduced by prehydration and oral probenecid before cidofovir administration. Complete blood counts should be monitored weekly (AIII).Īdverse effects of cidofovir include dose-related nephrotoxicity, neutropenia, uveitis, and hypotony (low intraocular pressure). For patients receiving foscarnet in the outpatient setting, serum electrolytes (including potassium, magnesium, calcium, and phosphorus) and renal function should be measured at least twice weekly during induction and at least weekly during maintenance therapy. Foscarnet often is given in the inpatient setting because of the intensity of monitoring and need for hydration. Genital ulcers also can occur during foscarnet administration in those who are incontinent to urine due to the toxic effects of excreted drug on exposed skin. Adverse effects of foscarnet include nephrotoxicity and electrolyte abnormalities seizures that occur characteristically in the context of renal insufficiency and anemia. 33,34 In patients receiving ganciclovir or valganciclovir, complete blood counts and renal function should be monitored twice weekly during induction and at least once weekly during maintenance therapy (AIII).

Ganciclovir-related neutropenia often can be reversed with granulocyte colony stimulating factor (G-CSF).

#RETINITIS DEFINITION TRIAL#

A randomized, placebo-controlled trial addressed whether valganciclovir (the current standard oral agent for treatment of CMV disease) in addition to ART might reduce CMV end-organ disease in AIDS patients at high risk (CD4 count 100cells/mm 3 for ≥3 months), the frequency of ophthalmologic follow-up can be decreased to every 3 months, but clinicians should be aware that lesion reactivation and retinal complications still occasionally occur in patients with immune reconstitution.Īdverse effects of ganciclovir/valganciclovir include anemia, neutropenia, thrombocytopenia, nausea, diarrhea, and renal dysfunction. 6 In patients with unilateral CMV retinitis and CD4 count 100 cells/mm 3 (BI). It occurs as unilateral disease in two-thirds of patients at presentation, but disease ultimately progresses to bilateral in most patients in the absence of therapy or immune recovery. Retinitis is the most common clinical manifestation of CMV end-organ disease in people with HIV. Therefore, regardless of whether or not anti-CMV therapy is continued, regular ophthalmologic follow-up is needed. Infection with a novel strain also may occur.Įnd-organ disease caused by CMV occurs in patients with HIV and advanced immunosuppression, typically those with CD4+ T lymphocyte cell (CD4) counts 100 cells/mm 3) relapse of the retinitis occurs at a rate of 0.03/person-year and has been documented 6 at CD4 counts as high as 1,250 cells/mm 3. Most clinical disease occurs in individuals previously infected with CMV experiencing reactivation of latent infection. Cytomegalovirus (CMV) is a double-stranded DNA virus in the herpesvirus family that can cause disseminated or localized end-organ disease in people with HIV with advanced immunosuppression.
