IBD in Special Populations

The single most important message: active IBD is worse for the pregnancy than most maintenance medications. Women who stop their biologics or immunomodulators "to protect the baby" often flare and harm the pregnancy. Educate with the phrase "baby does well when mom does well."

A critical counseling point: any infant born to a mother on biologics during the third trimester must NOT receive BCG at birth (standard in Saudi Arabia). Provide a written note for the pediatrician. Live vaccines are delayed until biologic levels clear (usually 6 months) or can be checked via infant drug levels.

Bowel ultrasound is the monitoring modality of choice in pregnancy—no radiation, safe, increasingly available in Saudi Arabia with trained sonographers. Partner with a radiology team versed in IBD bowel ultrasound (KFSHRC and a few tertiary centers have dedicated programs).

The highest-risk period for IBD flare is the first 6 months postpartum—do not stop biologics around delivery. Schedule the next dose to resume within 2 weeks of delivery. Many mothers stop biologics "to breastfeed safely" and then flare; education is critical.

Saudi patients and families often experience anxiety about leaving a trusted pediatric provider. Introduce the adult gastroenterologist by having them attend one or two pediatric visits before transition to build rapport. Provide Arabic-language patient education and encourage the patient to speak first in visits—even with parents present.

Shisha initiation is common in Saudi adolescents (often perceived as "safer" than cigarettes)—explicitly counsel that shisha is a proven Crohn's risk factor equal to or worse than cigarettes. Use a direct, non-judgmental tone; many families don't realize shisha is harmful.

The transfer document is the single most important artifact of transition—include not just medical data but psychosocial context, family dynamics, adherence patterns, and unresolved issues. Adult providers greatly appreciate this richer handover.

In a Saudi patient with IBD + axial spondyloarthritis, anti-TNF (infliximab or adalimumab) is the clear first-line biologic—it treats both. If considering vedolizumab for a patient with joint EIMs, anticipate worsening joint symptoms and discuss in advance; ustekinumab is a better alternative if anti-TNF contraindicated.

PG can mimic infected ulcers or vascular lesions—always biopsy to exclude alternatives and get dermatology consultation. The "pathergy phenomenon" means that biopsies themselves can worsen PG, so take a thin, peripheral biopsy and start treatment simultaneously. Never debride a PG ulcer.

A Saudi patient with IBD and sudden red painful eye needs same-day ophthalmology evaluation—do not delay. Uveitis untreated for days can cause permanent visual loss. Keep a 24/7 ophthalmology contact number in your IBD team's referral list.

PSC is asymptomatic for years; don't wait for jaundice. Annual alk phos + bilirubin + MRCP every 2–3 years (or annual in high-risk) catches early disease. Saudi tertiary hepatology centers (KFSHRC, KFMC, KAMC) run combined IBD-PSC clinics; refer early.

Vedolizumab is often the best first-line biologic in elderly IBD—gut-selective mechanism minimizes systemic immunosuppression and infection risk. Reserve anti-TNF for more aggressive disease or with strong joint EIM. Always assess for frailty with tools like Clinical Frailty Scale before treatment decisions.

Universal vitamin D supplementation is appropriate for Saudi IBD patients regardless of age—deficiency is endemic. In elderly, check 25-OH vitamin D level and replete to >30 ng/mL. This alone can reduce falls by 20% and support bone health in steroid users.

Shingrix (recombinant zoster vaccine) is now preferred over live zoster for all IBD patients on immunomodulators or biologics. Administer before starting JAK inhibitors (especially tofacitinib) which carry a 5-fold increased zoster risk. Saudi availability is increasing; check local supply.

When switching from JAK to biologic for pregnancy planning, allow 3 months remission stability before conception attempts. If flare occurs on switch, have a fallback plan (e.g., return to JAK briefly, or escalate to combination therapy) to avoid a pregnancy during active disease.

Perianal Crohn's in adolescents requires particularly sensitive counseling—embarrassment and cultural reluctance may cause late presentation or nonadherence. Have a male provider or nurse available for examinations, conduct exams with clear draping, and offer telemedicine for monitoring when appropriate.

Elderly IBD-PSC patients benefit from a dedicated combined clinic at a tertiary center with hepatology, GI, and ophthalmology co-located. Saudi tertiary centers (KFSHRC, KFMC) should develop these clinics. Transition to liver transplant evaluation at 8–10 years PSC duration is reasonable to initiate discussion, even if transplant is years away.

A well-run MDT saves time rather than consuming it. Average case discussion should be 5–10 minutes; longer means inadequate pre-meeting preparation or scope creep. Use a standard template and enforce time limits. Document a single MDT note per patient per meeting with clear action items.
