Vitamin C is a key to many important functions. It stimulates the immune system by protecting humans from infections and shows notable anti-viral and anti-inflammatory properties. With the antioxidative properties it acts against free radicals and cellular aging and prevents tumors. It is also involved in the synthesis of collagen, a structural protein that is essential for the formation of connective tissue as epidermis, muscle, bone, cartilage, etc. Vitamin C promotes the absorption of iron contributing to the production of red blood cells and the synthesis of hemoglobin. Scurvy is a nutritional disorder caused by low vitamin C levels which manifests with varied symptoms affecting multiple organ systems. Vitamin C also known as l-ascorbic acid, is a water-soluble nutrient and is a necessary element as the humans are unable to synthesize it. Vitamin C has an important role in the biochemical reactions of connective tissue synthesis. Presenting manifestations include malaise, gingival bleeding, impaired wound healing, perifollicular hemorrhage, dry hair and brittle nails, iron deficiency, muscle and joint pain, pulmonary hypertension, and other symptoms. The persistent reduced supply of vitamin C in the absence of treatment is cause of a severe progressive worsening of the clinical conditions. The disorder is uncommonly reported in high social level countries and in mentally wellbeing children.
Herewith, we report case-series of eight children with scurvy diagnosed in two Pediatric Hospitals in Catania, Italy "Policlinico G. Rodolico" and "Cannizzaro" in the last 2 years, October 2021-October 2023. In addition, a systematic literature review of 126 articles with 253 cases of scurvy including age, sex, main clinical manifestations, and eventual presence of neurodevelopmental disorders is reported. Main characteristic of vitamin C and negative effects of its lack with clinical manifestations, diagnosis, treatment, and prognosis are also referred.
Malnutrition, gastrointestinal, and neurological disorders, are the associated predisposing factors. In the present case-series, to the higher incidence of scurvy compared to others Italian Regions may have contributed an erroneous old prejudice of parents who refuse to give citrus fruits to young children as lemon and oranges may cause cystitis as well severe toxicity when mixed with milk.
This study aims to alert on the scurvy as a possible cause of childhood disorder also in well industrialized regions, and to offer diagnostic tools for identifying subjects suffering from this illness.
维生素C对许多重要功能起着关键作用。它通过保护人体免受感染来刺激免疫系统,具有显著的抗病毒和抗炎特性。凭借其抗氧化特性,它能对抗自由基和细胞衰老并预防肿瘤。它还参与胶原蛋白的合成,胶原蛋白是一种结构蛋白,对表皮、肌肉、骨骼、软骨等结缔组织的形成至关重要。维生素C促进铁的吸收,有助于红细胞的生成和血红蛋白的合成。坏血病是一种由维生素C水平过低引起的营养失调疾病,表现为影响多个器官系统的各种症状。维生素C也被称为L - 抗坏血酸,是一种水溶性营养素,由于人类无法合成它,所以它是必需元素。维生素C在结缔组织合成的生化反应中起重要作用。其表现包括不适、牙龈出血、伤口愈合受损、毛囊周围出血、头发干燥和指甲脆弱、缺铁、肌肉和关节疼痛、肺动脉高压等症状。在未治疗的情况下,维生素C持续供应减少会导致临床状况严重逐渐恶化。在社会经济水平较高的国家和心理健康的儿童中,这种疾病的报告并不常见。
在此,我们报告了意大利卡塔尼亚的两家儿科医院“波利克林尼科·G·罗多利科”医院和“坎尼扎罗”医院在过去两年(2021年10月至2023年10月)诊断出的8例坏血病患儿的病例系列。此外,还报告了对126篇文章中253例坏血病病例的系统文献综述,包括年龄、性别、主要临床表现以及是否存在神经发育障碍。还提及了维生素C的主要特性及其缺乏的负面影响、临床表现、诊断、治疗和预后。
营养不良、胃肠道和神经系统疾病是相关的易感因素。在本病例系列中,与意大利其他地区相比,坏血病发病率较高可能是由于父母存在错误的旧观念,他们拒绝给幼儿食用柑橘类水果,因为柠檬和橙子可能会导致膀胱炎,并且与牛奶混合时会产生严重毒性。
本研究旨在提醒人们注意坏血病可能是工业化程度较高地区儿童疾病的一个原因,并提供诊断工具以识别患有这种疾病的患者。
