Early biologics vs immunomodulators in jejunal CD

What is known

• A systematic review of UGICD (esophagus/stomach/duodenum/jejunum) found only observational data for anti-TNF, six studies, none RCTs, results heterogeneous. ¹
• In 39 adults with jejunal CD, infliximab gave higher 1-year segmental endoscopic and ulcer healing than ustekinumab, with vedolizumab lowest, a biologic-vs-biologic, not early-vs-immunomodulator, comparison. ¹
• Pediatric cohorts report durable clinical/endoscopic improvement with proximal disease but explicitly did not attribute long-term outcomes to specific regimens given retrospective design and evolving therapy. ^2,3

What is unknown / caveats

• No RCT and no direct early-biologic vs immunomodulator comparison in isolated jejunal CD
• Jejunal disease pooled within broader UGICD; outcomes not isolated
• Pediatric cohorts retrospective, small, confounded by evolving treatment strategies
• The corpus contains no trial isolating early-biologic timing against immunomodulators for jejunal disease.
