Arthritis associated with ventriculoatrial shunt

Area of Science:

• Nephrology
• Rheumatology
• Pediatric Surgery

Background:

• Ventriculoatrial shunts are used to treat hydrocephalus.
• Infected shunts can lead to immune complex-mediated diseases like glomerulonephritis.
• Arthritis is a rarely described complication of infected shunts.

Observation:

• A pediatric patient with hydrocephalus presented with acute, recurrent arthritis.
• The arthritis persisted for 8 months prior to the development of nephritis.
• The patient had an infected ventriculoatrial shunt.

Findings:

• The case demonstrates arthritis as an additional manifestation of immune complex formation secondary to an infected ventriculoatrial shunt.
• This presentation is uncommon, with glomerulonephritis being the more frequently reported immune complication.
• The findings suggest a broader spectrum of immune-mediated complications from infected shunts.

Implications:

• Clinicians should consider arthritis in the differential diagnosis of recurrent joint pain in patients with infected ventriculoatrial shunts.
• Early recognition and management of shunt infections may prevent severe complications like nephritis and arthritis.
• Further research is warranted to understand the mechanisms linking shunt infections to arthritis.
