In Henoch-Schonlein purpura, which ongoing evaluation is essential to monitor for renal involvement?

• A. ANA titers
• B. Chest radiographs
• C. Blood pressure measurement
• D. Liver function studies

Answer: (C)

In Henoch-Schonlein purpura, the kidneys can be affected by a form of nephritis, so keeping a close eye on renal function is crucial. Regular blood pressure measurement is essential because hypertension can reflect renal involvement and evolving nephritis. Tracking blood pressure over time helps detect worsening kidney function early and guides further evaluation or referral if needed. The other options don’t target kidney status: ANA titers are used to screen for autoimmune conditions like lupus rather than HSP-related kidney disease; chest radiographs aren’t relevant to renal monitoring in this condition; and liver function studies assess the liver, not kidney involvement. In practice, a urinalysis for protein and blood is also important, but among the choices given, regular blood pressure checks best monitor renal involvement.
