CMV COLITIS • Defective cell-mediated immunity: • AIDS, organ transplant recipients, immunosuppression • Old age, cancer, CRF, alcoholism • Immunocompetent hosts : Mucosal damage
EPIDEMIOLOGY IN IBD • More common in UC - Prevalence: 4.6% in UC, 0.8% in Crohn’s disease - 12% of patients with intestinal CMV infection Kaufman et al. Dis Colon Rectum 1999; 42: 24 • Usually reactivation of latent virus
PREDISPOSING FACTORS • Duration of IBD • Active inflammation • Treatment - Steroids with other immunosuppression Often in a patient who had long been stable Kishore et al. J med microbiol 2004;53
CLINICAL CHARACTERISTICS • Exacerbation of the underlying IBD • Mononucleosis-like syndrome • Steroid -refractory colitis • Additional GI manifestations – oral lesions, odynopagia Papadakis et al. Am J Gastroenetrolgy 2001; 96:7 Kambham et al. Am J Surg pathol 2004; 28:3
DIAGNOSIS • Serology • CMV antigenemia • PCR for CMV • Endoscopic appearance - Erosions, ulcerations, mucosal hemorrhage • Mucosal biopsy -Large cells with intranuclear and intracytoplasmic inclusions - Immunostaining - Submucosal vasculitis or microvascular thrombosis
TREATMENT • Gancyclovir • 5 mg/kg bid • 6 weeks of intravenous treatment • Marked improvement usually noted within a week
TREATMENT STOP! • Steroids (rapid tapering) • Cyclosporin • Azathioprine • 6-MP
