Ogilvie's Syndrome Following Herpes Zoster Infection: A Comprehensive Review of the Literature.

This systematic review explores the association between herpes zoster (HZ) infection and Ogilvie's syndrome (acute colonic pseudo-obstruction), evaluating how varicella-zoster virus (VZV) reactivation may contribute to autonomic dysfunction leading to intestinal obstruction. A comprehensive search was conducted in PubMed, Scopus, and Cochrane Library databases up to October 2024, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies included case reports, clinical images, and letters reporting Ogilvie's syndrome secondary to HZ or VZV infection. After screening 219 publications and additional grey literature, 27 studies describing 28 cases met the inclusion criteria. Data were extracted on patient demographics, clinical manifestations, diagnostic methods, and outcomes. The quality of studies was assessed using the Joanna Briggs Institute critical appraisal checklist. The results from 27 studies encompassing 28 patients with intestinal pseudo-obstruction secondary to VZV or HZ infection indicated a mean age of 60 years, predominantly affecting males (71.5%). Notably, 47.6% had underlying immunosuppressive conditions. The primary clinical manifestations included abdominal distention and severe constipation. Most patients (93%) exhibited a herpetiform rash, primarily in thoracic dermatomes. Symptoms of pseudo-obstruction often preceded the rash (58%), and imaging in the vast majority revealed colonic distension with no intra-abdominal pathology. Treatment focused on conservative management of both pseudo-obstruction and HZ symptoms, with 93% of patients achieving full recovery, while the mortality rate was identified at 7%. The findings suggest that HZ-induced Ogilvie's syndrome may be an underdiagnosed condition, requiring a high index of suspicion, particularly in immunocompromised patients. Early recognition and conservative treatment can prevent unnecessary surgical interventions. Further studies are needed to clarify the pathophysiological mechanisms linking VZV reactivation to colonic pseudo-obstruction.
