Abstract

Acute hepatic porphyria is a genetic disorder affecting enzymes involved in heme biosynthesis. The most common subtype is acute intermittent porphyria, accounting for 80% of cases. Other types include hereditary coproporphyria, variegate porphyria, and delta-aminolevulinic acid dehydratase deficiency. Attacks in acute hepatic porphyria are triggered by the induction of hepatic ALA synthase 1, leading to the accumulation of neurotoxic heme intermediates, delta-aminolevulinic acid, and porphobilinogen. Women experience attacks more frequently than men. Acute porphyria attacks are characterized by severe, diffuse abdominal pain, muscle weakness, autonomic neuropathy (including hypertension, tachycardia, nausea, vomiting, and constipation), and changes in mental status. Early recognition of the disease is crucial as it requires urgent medical attention and treatment. Management includes intravenous opioids, glucose, hemin, and the removal of triggering factors. Preventive treatment options include hormone suppression therapy, off-label prophylactic hemin, Givosiran, and exceptionally liver transplantation.

摘要

急性肝卟啉病是一种影响血红素生物合成相关酶的遗传性疾病。最常见的亚型是急性间歇性卟啉病,占病例的80%。其他类型包括遗传性粪卟啉病、混合型卟啉病和δ-氨基-γ-酮戊酸脱水酶缺乏症。急性肝卟啉病的发作是由肝脏δ-氨基-γ-酮戊酸合酶1的诱导引发的,导致神经毒性血红素中间体、δ-氨基-γ-酮戊酸和卟胆原的积累。女性比男性更频繁地发作。急性卟啉病发作的特征是严重的弥漫性腹痛、肌肉无力、自主神经病变(包括高血压、心动过速、恶心、呕吐和便秘)以及精神状态改变。尽早识别该疾病至关重要,因为它需要紧急医疗关注和治疗。治疗包括静脉注射阿片类药物、葡萄糖、血红素以及去除触发因素。预防性治疗选择包括激素抑制疗法、非标签预防性血红素、吉沃赛仁,以及在特殊情况下进行肝移植。
