The noble false widow Steatoda nobilis is the only medically significant spider known to occur in the British Isles and Ireland, with a single case of steatodism ever reported from Great Britain. We present here five new cases of envenomations by S. nobilis, three from Ireland and two from Great Britain and describe symptoms not previously reported for the genus Steatoda.
Four adult males and one adult female with confirmed S. nobilis bites reported their symptoms to the authors. General practitioner chart was obtained for case #3. In all five cases, envenomations were immediately followed by a sharp and prolonged onset of pain, mild to extensive erythema and localised to extensive swelling around the bite site. Additional symptoms include moderate to intense pruritus, vasodilation of the capillaries around the bite site and a possible minor necrotic wound.
In all cases, symptoms subsided within 48-72 h and no further complications were reported. Envenomations by S. nobilis seem to produce symptoms similar (but not identical) to those previously reported from other Steatoda sp. Considering their benign outcome, envenomations by S. nobilis should still be regarded as of moderate medical importance, requiring monitoring and pain management strategies.
高贵的假寡妇蛛 Steatoda nobilis 是唯一已知在不列颠群岛和爱尔兰发生的具有医学重要性的蜘蛛，英国曾有一例 steatodism 报告。我们在此介绍 5 例新的 S. nobilis 咬伤病例，其中 3 例来自爱尔兰，2 例来自英国，并描述了以前未报告过的 Steatoda 属症状。
4 名成年男性和 1 名成年女性被确诊为 S. nobilis 咬伤，向作者报告了他们的症状。第 3 例的全科医生图表已获得。在所有 5 例中，咬伤后立即出现剧烈且持续的疼痛、轻度至广泛的红斑以及咬伤部位局部至广泛肿胀。其他症状包括中度至剧烈瘙痒、咬伤部位毛细血管扩张和可能的轻微坏死性伤口。
在所有病例中，症状在 48-72 小时内消退，没有报告其他并发症。S. nobilis 的咬伤似乎产生与以前报告的其他 Steatoda sp 相似（但不完全相同）的症状。考虑到它们良性的结果，S. nobilis 的咬伤仍应被视为具有中等医学重要性，需要监测和疼痛管理策略。
