A 55 year old male presents with a history of chronic dyspepsia and with recent weight loss. Investigation by gastroscopy reveals a reduction in specialised gastric glands and the presence of slender giemsa staining filaments on the mucosal surface. In addition a gastric mass is seen. This is composed of large B lymphocytes which are negative for cyclin D1 and BCL2. Monoclonality is identified.
A 28-year-old woman was found to have stage IV Burkitt s lymphoma. Her renal function was normal and a staging CT scan had shown no abnormality of the renal tract. Three days later, when she was about to start chemotherapy, she developed a temperature of 39.0 C with rigors and was treated with imipenem. Investigations (the following day):serum sodium 138 mmol/L (137 144)serum potassium 6.2 mmol/L (3.5 4.9)serum creatinine 215 mol/L (60 110)serum corrected calcium 1.60 mmol/L (2.20 2.60)serum phosphate 1.52 mmol/L (0.8 1.4)serum lactate dehydrogenase 1238 U/L (10 250)serum urate 0.69 mmol/L (0.19 0.36)What is the most likely cause of the renal impairment?
