Careful monitoring and individualized risk assessment are recommended when prescribing tirzepatide to patients with pre-existing gastrointestinal disorders.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Tirzepatide, a dual agonist of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors, has demonstrated marked efficacy in glycemic control and weight reduction but is frequently associated with gastrointestinal adverse effects.

Abstract

Tirzepatide, a dual agonist of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors, has demonstrated marked efficacy in glycemic control and weight reduction but is frequently associated with gastrointestinal adverse effects. Data on its safety in patients with celiac disease are limited. We describe a 40-year-old woman with well-controlled celiac disease on a strict gluten-free diet who developed severe watery diarrhea immediately after the first 2.5 mg dose of tirzepatide, initiated for weight management. She experienced up to ten diarrheal episodes per day with dehydration and fatigue, requiring intravenous fluid replacement. Laboratory evaluation revealed mild hypokalemia and elevated AST. No infectious or dietary triggers were identified. Tirzepatide was discontinued, resulting in complete symptom resolution. Gastrointestinal intolerance is a known dose-dependent adverse effect of tirzepatide; however, such acute and severe reactions at the starting dose are uncommon. The coexistence of celiac disease may have increased susceptibility to enteric side effects through altered intestinal mucosal or immune mechanisms. This case highlights the potential for severe gastrointestinal intolerance to tirzepatide, even at low doses, in patients with celiac disease. Careful monitoring and individualized risk assessment are recommended when prescribing tirzepatide to patients with pre-existing gastrointestinal disorders.

Özet

Glukagon benzeri peptid-1 (GLP-1) ve glukoz bağımlı insülinotropik polipeptid (GIP) reseptörlerinin dual agonisti olan Tirzepatid, glisemik kontrol ve kilo kaybında belirgin etkinlik göstermiştir ancak sıklıkla gastrointestinal yan etkilerle ilişkilendirilmektedir. Çölyak hastalığı olan hastalarda kullanımına ilişkin güvenlik verileri sınırlıdır. Kilo yönetimi amacıyla başlanan 2,5 mg'lık ilk tirzepatid dozundan hemen sonra şiddetli sulu diyare gelişen, sıkı bir glutensiz diyetle kontrol altında olan 40 yaşında bir kadın çölyak hastasını sunuyoruz. Hasta, dehidrasyon ve halsizliğin eşlik ettiği, intravenöz sıvı replasmanı gerektiren, günde on keze varan diyare atakları yaşamıştır. Laboratuvar değerlendirmesinde hafif hipokalemi ve yüksek AST saptanmıştır. Herhangi bir enfeksiyöz veya diyetsel tetikleyici tanımlanmamıştır. Tirzepatid tedavisi sonlandırılmış ve semptomlar tamamen düzelmiştir. Gastrointestinal intolerans, tirzepatidin bilinen ve doza bağlı bir yan etkisidir ancak başlangıç dozunda bu denli akut ve şiddetli reaksiyonlar nadirdir. Mevcut çölyak hastalığı, değişmiş bağırsak mukozası veya immün mekanizmalar yoluyla enterik yan etkilere duyarlılığı artırmış olabilir. Bu olgu, çölyak hastalarında düşük dozlarda bile tirzepatide karşı şiddetli gastrointestinal intolerans potansiyelini vurgulamaktadır. Önceden var olan gastrointestinal bozukluğu olan hastalara tirzepatid reçete edilirken dikkatli izlem ve bireyselleştirilmiş risk değerlendirmesi önerilir.
