Baseline Assessment | Test | Advice |
---|---|---|
Cardiac Evaluation& | ECG to exclude baseline bradyarrythmias or conduction blocks, blood pressure, check drug history for medications that may slow heart rate or AV conduction | Cardiac contraindications: MMI, unstable angina, class III or IV heart failure, type 2 second degree or type 3 degree AV block, sick sinus syndrome, significant QTc prolongation |
Complete Blood Count | Including lymphocyte count | Patients with counts <0.2 × 109/L were excluded from trial programs, a mean 50% reduction in total lymphocyte count is expected |
Liver Function Tests | Transaminases and bilirubin level | 5% develop transaminitis > 3x ULN |
Ophthalmic Assessment | Fundoscopy | Patients with a history of diabetes, uveitis or macular edema |
Virology and TB | Hep B, VZV serology and TB IGRA | Consider VZV vaccination if VZV IgG negative (live vaccines require administration 3 months prior to initiation). Herpes zoster is the most common opportunistic infection |
Other contraindications | Patient history | TIA or stroke < 6 months, severe untreated sleep apnea |
Review current or prior medications | Patient history | Anti-neoplastic, immunosuppressive, or immune-modulating therapies may lead to unintended additive immunosuppression. Monoaminooxidase inhibitors are contraindicated |
Dose titration at start | Titrate once daily dose to maintenance dose at one week: 0.25mg days 1–4, 0.5mg days 5–7, then 1mg QD |
Request cardiologist consultation in patients with a preexisting cardiac condition.AV, atrioventricular; ECG, electrocardiogram; VZV, varicella-zoster virus; MI, myocardial infarction; QTc, QT Interval; ULN, upper limit of norm; TB, tuberculosis; IGRA, interferon-gamma release assays; Hep B, hepatitis B virus; TIA, transient ischemic attack; QD, every day.
