Acute scurvy during treatment with interleukin-2.
The association of vitamin C deficiency with nutritional factors is commonly recognized. However, an acute form of scurvy can occur in patients with an acute systemic inflammatory response, which is produced by sepsis, medications, cancer or acute inflammation. The frequency of acute hypovitaminosis C in hospitalized patients is higher than previously recognized. We report the occurrence of acute signs and symptoms of scurvy (perifollicular petechiae, erythema, gingivitis and bleeding) in a patient hospitalized for treatment of metastatic renal-cell carcinoma with high-dose interleukin-2. Concomitantly, serum vitamin C levels decreased to below normal. Better diets and longer lifespan may result a lower frequency of acute scurvy and a higher frequency of scurvy associated with systemic inflammatory responses. Therefore, increased awareness of this condition can lead to early recognition of the cutaneous signs of acute scurvy in hospitalized patients with acute illnesses or in receipt of biological agents, and prevent subsequent morbidity such as bleeding, anaemia, impaired immune defences, oedema or neurological symptoms.
