D-lactic acidosis is an infrequent complication, mainly reported in patients with short bowel syndrome. It is characterized by recurrent episodes of encephalopathy with elevated serum D-lactic acid, usually associating metabolic acidosis. The presence of D-lactate-producing bacteria is necessary for the development of this complication. Other factors, such as the ingestion of large amounts of carbohydrates or reduced intestinal motility, contribute to D-lactic acidosis. We report a case of recurrent D-lactic acidosis in a 5-year-old girl with short bowel syndrome, due to a midgut volvulus. She initially received oral antibiotics in order to treat bacterial overgrowth, together with oral carbohydrates restriction. Nevertheless, recurrences did occur. Subsequently, 25% of the enteral nutrition was replaced for a formula containing fructose exclusively, while other fermentable sugars were restricted from the diet. After 16 years of follow up, further recurrences of D-lactic acidosis were not observed.
D-乳酸酸中毒是一种罕见的并发症,主要见于短肠综合征患者。其特征为反复出现脑病发作,血清D-乳酸水平升高,通常伴有代谢性酸中毒。D-乳酸产生菌的存在是该并发症发生的必要条件。其他因素,如大量摄入碳水化合物或肠道蠕动减弱,也会导致D-乳酸酸中毒。我们报告一例5岁短肠综合征女童因中肠扭转发生反复D-乳酸酸中毒的病例。她最初接受口服抗生素治疗细菌过度生长,并限制口服碳水化合物摄入。然而,病情仍有复发。随后,将25%的肠内营养替换为仅含果糖的配方奶,同时从饮食中限制其他可发酵糖。经过16年的随访,未观察到D-乳酸酸中毒的进一步复发。
