Intestinal pseudo-obstruction caused by herpes zoster: Case report and pathophysiology

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.

Postoperative abdominal herpes zoster complicated by intestinal obstruction: A case report

BACKGROUND

Intestinal obstruction is a common occurrence in clinical practice. However, the occurrence of herpes zoster complicated by intestinal obstruction after abdominal surgery is exceedingly rare. In the diagnostic and treatment process, clinicians consider it crucial to identify the primary causes of its occurrence to ensure effective treatment and avoiding misdiagnosis.

CASE SUMMARY

Herein, we present the case of a 40-year-old female patient with intestinal obstruction who underwent laparoscopic appendectomy and developed herpes zoster after surgery. Combining the patient's clinical manifestations and relevant laboratory tests, it was suggested that the varicella zoster virus reactivated during the latent period after abdominal surgery, causing herpes zoster. Subsequently, the herpes virus invaded the visceral nerve fibers, causing gastrointestinal dysfunction and loss of intestinal peristalsis, which eventually led to intestinal obstruction. The patient was successfully treated through conservative treatment and antiviral therapy and subsequently discharged from the hospital.

CONCLUSION

Pseudo-intestinal obstruction secondary to herpes zoster infection is difficult to distinguish from mechanical intestinal obstruction owing to various causes. In cases of inexplicable intestinal obstructions, considering the possibility of a viral infection is essential to minimize misdiagnosis and missed diagnoses.

A Report of a Case of Segmental Zoster Paresis Demonstrated by Limb Paralysis and a Review of the Literature

Varicella zoster virus (VZV) lies dormant in our spinal dorsal root ganglia until reactivation occurs and causes herpes zoster. VZV can spread from the dorsal root to the neighboring ventral root and cause subsequent segmental paresis. In this case report, we present the case of a 78-year-old female who was hospitalized after she developed right upper extremity paresis and altered mental status four days after the eruption of a vesicular rash involving the same dermatome. The patient received intravenous acyclovir, gabapentin, and inpatient rehabilitation. She was found to have made a full recovery one year later. Pain and a vesicular rash is the most common presentation of VZV infection in the elderly. However, segmental zoster paresis should be suspected in any patient with paralysis and a recent diagnosis of herpes zoster.

Resolution of herpes zoster-induced small bowel pseudo-obstruction by epidural nerve block: A case report

BACKGROUND

When herpes zoster is complicated with paralytic ileus, this mostly involves acute intestinal pseudo-obstruction of Ogilvie's syndrome manifesting as obvious dilatation of the cecum and right colon; small intestinal obstruction is rare. Here, we present a patient with a very rare case of small bowel pseudo-obstruction.

CASE SUMMARY

A 76-year-old female patient complained of right upper quadrant pain. Two days later, a blistering, right-sided rash of the thoracoabdominal dermatome (T5-T10) emerged in conjunction with small intestinal dilatation and the inability to defecate. Computed tomography of the abdomen confirmed small bowel pseudo-obstruction. Antiviral therapy, gastrointestinal decompression, and enemas proved unproductive. After 4 d of stagnation, an epidural block was performed for pain relief and prompted the passage of gas and stool, resolving the obstructive problem. Three days later, the rash appeared dry and crusted, and the pain diminished. After 5 d, no abnormality was visible by gastroenteroscopy, and the patient was discharged on day 7.

CONCLUSION

This case shows that herpes zoster may induce small bowel pseudo-obstruction in addition to colonic pseudo-obstruction. Epidural block can not only treat intercostal neuralgia but also resolve small bowel pseudo-obstruction caused by herpes zoster.

Acute myelitis with multicranial neuritis caused by Varicella zoster virus: a case report

Background

Varicella zoster virus (VZV) can remain lifelong in the latent state in ganglionic neurons and adrenal glands after the initial infection. However, it can be reactivated anytime and can trigger several severe neurological manifestations such as encephalitis, meningitis, Ramsay-Hunt syndrome, cerebellitis, myelitis, and stroke. In addition, due to the diversity of clinical manifestations, clinical diagnosis of VZV can be difficult, especially in the absence of varicella. Here, we describe the case of a 52-year-old male who presented with symptoms of acute myelitis as well as polycranial neuritis, and was finally diagnosed with VZV infection through metagenomic next-generation sequencing (mNGS).

Case presentation

A 52-year-old male came to our hospital with complaint of headache, fever, weakness of right lower limb, abdominal distension, and hearing loss. T2-weighted MRI revealed a hyperintense lesion in the spinal cord extending from T8 to T11. In addition, enhanced MRI showed small patches and strips hyperintensities in both the spinal cord and meninges. Plain abdominal radiographs and abdominal computed tomography (CT) scan displayed air-fluid levels and incomplete bowel obstruction. Moreover, electrophysiological evaluation of the peripheral neuropathy in the extremities was found to be normal. Finally, by using metagenomic next-generation sequencing (mNGS) we found that the copy number of VZV DNA in cerebrospinal fluid (CSF) was significantly increased and IgG antibody against VZV in CSF was also noted to be positive. Hence, VZV infection was identified in patient’s central neuron system. Finally, after a few days of low dose steroid treatment, the patient's symptoms were found to be significantly improved.

Conclusions

The findings indicate that we should pay proper attention to the various symptoms caused by VZV infection due to the clinical heterogeneity, especially in the absence of cutaneous lesions.

Segmental zoster paresis as a cause for persistent fever in an immunocompromised patient

Herpes zoster reactivation is a frequently encountered condition that can result in several uncommon complications. This case report highlights one such frequently overlooked complication, segmental zoster paresis. We discuss a case of prolonged fever and lower limb weakness in an immunocompromised patient with breast cancer on active chemotherapy after resolution of a herpetiform rash in the L2, L3 and L4 dermatomes. Early investigation with lumbar puncture, looking for cerebrospinal fluid pleocytosis, varicella zoster virus detection by PCR or molecular testing and immunoglobulins against varicella zoster virus, should be undertaken to support the diagnosis. Nerve conduction studies, electromyography and MRI of the spine can sometimes help with neurolocalisation. Intravenous acyclovir and a tapering course of steroids can help with resolution of symptoms. The variegate presentation can make diagnosis challenging. Awareness and a high index of suspicion can prevent delays in diagnosis and treatment and improve patient outcomes.

Could Chronic Idiopatic Intestinal Pseudo-Obstruction Be Related to Viral Infections?

Chronic idiopathic intestinal pseudo-obstruction (CIIPO) is a disease characterized by symptoms and signs of small bowel obstruction in the absence of displayable mechanical obstruction. Due to the known neuropathic capacity of several viruses, and their localization in the intestine, it has been hypothesized that such viruses could be involved in the pathogenesis of CIIPO. The most frequently involved viruses are John Cunningham virus, Herpesviridae, Flaviviruses, Epstein-Barr virus and Citomegalovirus. Therefore, the present narrative review aims to sum up some new perspectives in the etiology and pathophysiology of CIIPO.

Frequency of subclinical herpes zoster in pediatric hematology-oncology patients receiving chemotherapy: A retrospective cohort analysis

Varicella-zoster virus (VZV) reactivation from the enteric nervous system can cause ileus (Ogilvie's syndrome) in adult patients. Since no pediatric cases have been described, we sought to retrospectively analyze VZV reactivation in pediatric hematology-oncology patients to determine whether VZV infection including subclinical VZV reactivation can induce gastrointestinal complications such as Ogilvie's syndrome. Thirty-five patients who received chemotherapy at our institution between September 2013 and June 2018 were included. Serum samples were collected weekly during hospitalization and every 3 months during outpatient maintenance chemotherapy. A real-time polymerase chain reaction assay was used to measure VZV DNA load in serum. The clinical features of patients with VZV infection were retrospectively analyzed. Of 1165 serum samples, 7 (0.6%) were positive for VZV DNA. VZV DNA was detected in 3 of 35 patients. In patient A, VZV DNA was detected during two episodes. The first episode involved varicella-like eruptions caused by the Oka VZV vaccine strain. The second episode involved herpes zoster (HZ) caused by the same strain. Patients B and C had a clinical course that was typical for HZ caused by wild-type VZV. No gastrointestinal symptoms were observed at the time of VZV infection in these three patients. VZV DNA was not detected in any other samples. No pediatric cases with Ogilvie's syndrome caused by VZV reactivation were demonstrated in this cohort. Additionally, no subclinical VZV reactivation was found in this cohort. Further study is needed to elucidate the precise incidence of pediatric Ogilvie's syndrome caused by VZV reactivation.
