Immunosuppressive and biologic therapies — branching viva

A branching viva following one child from the decision to start methotrexate in juvenile idiopathic arthritis through the weekly dose and folic acid, the full-blood-count and liver-enzyme monitoring, the weekly-versus-daily distinction, and the transition to an anti-tumour necrosis factor biologic with the dual tuberculosis screen and the live-vaccine rule.

Prompt
A six-year-old child with polyarticular juvenile idiopathic arthritis is to start methotrexate, and later progresses to an anti-tumour necrosis factor biologic. The examiner releases information in stages. The candidate must state the methotrexate schedule and monitoring, recognise the daily-dosing error, and build the pre-biologic screen and the live-vaccine plan.

Branching cross-examination

This is a MedVellum formative viva. It is not an official RACP, MRCPCH, ABP, ACGME or RCPSC station, mark scheme, duration or pass standard. Release each update only after the candidate states the principle, the dose, and the safeguard. [5] [9]

Candidate brief

You are the paediatric registrar in a rheumatology joint clinic. Speak as you would when starting a child on methotrexate and later on a biologic. State the schedule, the safeguard, and the monitoring at each step. This is one continuous case. Each escalation branch leads to the next update. [5]
