一位50歲女性抵達風濕免疫科門診進行追蹤。為了強烈壓制猛烈爆發的紅斑性狼瘡與類風濕性關節炎，她在過去三個月內持續吞服高劑量的口服皮質類固醇 (Prednisone)。個案向護理師發牢騷：「發炎確實完全消失了，但我現在覺得自己像個變種人！我的臉完美地膨脹圓得像氣球，上背部長出了一個厚實的脂肪肉瘤，而且明明我以前從來沒有糖尿病史，我昨天的血糖竟然驚人地飆到了 220 mg/dL！甚至別人只是打個噴嚏我就會立刻被傳染發高燒。」嚴格基於長期且全身性的皮質類固醇治療，護理師深知哪些主訴或額外風險是該藥物極具獨特性且可預期的副作用？（多選題）
A 50-year-old female arrives at the rheumatology clinic for a follow-up. To intensely suppress an aggressive flare-up of Lupus and Rheumatoid Arthritis, she has been ingesting high-dose oral corticosteroids (Prednisone) consistently for the past three months. The client groans to the nurse, "The inflammation is completely gone, but I feel like a mutant! My face has ballooned perfectly round, I've developed a thick fatty hump on my upper back, my blood sugar shockingly spiked to 220 mg/dL despite no history of diabetes, and I seem to catch a bad fever instantly from anyone who sneezes." Based strictly on prolonged, systemic corticosteroid therapy, the nurse knows which of these complaints and additional risks are distinctly predictable drug side effects? (Select all that apply.)
- AThe development of a classic "moon face" and "buffalo hump" due to radical fat redistribution.✓ 正解由於顯著的脂肪重新分佈，出現典型的「月圓臉」和「水牛肩」。
- BSevere medication-induced hyperglycemia resulting directly from heightened hepatic gluconeogenesis.✓ 正解由於肝臟糖質新生作用增強，導致嚴重的藥物誘發性高血糖。
- CA profound overabundance and hyper-vigilance of the immune system, forcing her to intensely fight off, rather than catch, infections.免疫系統過度活躍且高度警戒，迫使她激烈對抗而非感染疾病。
- DAn extremely elevated risk for developing fragile, devastating bone fractures driven by insidious osteoporosis.✓ 正解由於隱匿性骨質疏鬆症驅動，發展脆弱且毀滅性骨骨折的極高風險。
- EGastric erosions or peptic ulcers, notably heavily exacerbated if she routinely pairs her steroids with NSAIDs.✓ 正解胃黏膜侵蝕或消化性潰瘍，若常規將類固醇與NSAIDs併用則會顯著惡化。
本題測驗藥理大魔王：長期使用全身性皮質類固醇（Corticosteroids, 如 Prednisone, Cortisone）的副作用圖譜。長期高劑量的類固醇會系統性地引起醫源性庫欣氏症候群（Cushing's Syndrome）。這包含了：強制重金屬脂肪重新分配（Fat redistribution），導致經典的月亮臉（Moon face）與水牛肩（Buffalo hump）（選項A正確）；在肝臟激發強烈糖質新生與抵抗胰島素，引發極度嚴重的類固醇誘發性高血糖（Hyperglycemia）（選項B正確）；剝奪骨骼中的鈣質導致惡劣的退化性骨質疏鬆症，引發輕微碰撞即脊椎骨碎裂的風險（選項D正確）；並破壞胃壁的前列腺素保護層，尤其與 NSAIDs （如布洛芬止痛藥）合併使用時極易導致穿孔性胃潰瘍出血（選項E正確）。唯一錯誤的是選項C。類固醇的精髓在於「全面鎮壓免疫系統（Immunosuppression）」，而非使之擁有過度警惕。白血球功能被癱瘓，病患會像缺乏防護罩般，極容易感染小細菌並發展為致命敗血症（這是其最可怕的副作用之一）。
Long-term high-dose corticosteroid therapy induces iatrogenic Cushing’s syndrome, characterized by fat redistribution causing moon face and buffalo hump, and increased hepatic gluconeogenesis leading to hyperglycemia. Chronic use also accelerates bone loss, increasing fracture risk from osteoporosis, and compromises gastric mucosa, raising the likelihood of peptic ulcers, especially when combined with NSAIDs. Unlike option C, steroids suppress immune function, significantly increasing susceptibility to infections rather than enhancing vigilance.
「類固醇副作用大亂鬥」是所有醫護執照考試必出的經典。除了背誦經典體態 (月亮臉水牛肩)，重點是理解它『升高血糖、誘發潰瘍、免疫低下容易死亡、骨頭變脆』的生化學邏輯，全世界都愛考。
