Peripheral gangrene is rare in children. Protein C, protein S, and antithrombin deficiency, positivity for anticardiolipin antibodies or lupus anticoagulant and factor V Leiden mutation are important causes of thrombosis in the venous system. There is paucity of literature on the contribution of these factors in children with peripheral gangrene. We evaluated the role of aforementioned factors in children with peripheral gangrene. Protein S deficiency was seen in one case and another was transiently positive for lupus anticoagulant. None of the 11 age- and sex-matched normal controls had protein C, protein S, or antithrombin deficiency. Our results indicate that deficiency of protein C, protein S, and antithrombin, and positivity for anticardiolipin antibodies, lupus anticoagulant, and factor V Leiden are uncommon causes of peripheral gangrene in children in north-western India. Fibrinolytic and antiplatelet parameters were not tested. Testing for these may yield further clues to the etiology of this condition.
周围性坏疽在儿童中较为罕见。蛋白 C、蛋白 S 和抗凝血酶缺乏、抗心磷脂抗体或狼疮抗凝物阳性以及因子 V Leiden 突变是静脉系统血栓形成的重要原因。关于这些因素在儿童周围性坏疽中的作用,文献报道较少。我们评估了上述因素在儿童周围性坏疽中的作用。1 例患儿存在蛋白 S 缺乏,另 1 例患儿狼疮抗凝物一过性阳性。11 例年龄和性别匹配的正常对照者均无蛋白 C、蛋白 S 或抗凝血酶缺乏。我们的结果表明,在印度西北部,蛋白 C、蛋白 S 和抗凝血酶缺乏以及抗心磷脂抗体、狼疮抗凝物和因子 V Leiden 阳性并不是儿童周围性坏疽的常见原因。我们未检测纤维蛋白溶解和抗血小板参数。对此类参数的检测可能会为该疾病的病因提供更多线索。
