Review of the Role of Enteral Factor in the Development of Secondary Hyperoxaluria

Abstract

Objectives: Discuss the role of the enteric factor in the hyperoxaluria development. Methods: Using the Internet and written materials, the relevant factors of enteral factor; hyperoxaluria; oxalotrophia; Oxalobacter formigenes; kidney stones, and with 36 references, were comprehensively analyzed and studied. Results: Under the condition of excessive intake of oxalate and its precursors, increased intestinal absorption of oxalate and imbalance of intestinal flora, resulting in increased urine oxalate and calcium oxalate crystal, which lead to hematuria, proteinuria, recurrent kidney stones and nephrocalcinosis. Discussion: Hyperoxaluria is a disease caused by metabolism disorder of oxalic acid and intestinal factors have significant influence on its progression. This disease can occur under the condition of excessive intake of oxalate and its precursors, increased intestinal absorption of oxalate and imbalance of intestinal flora, resulting in increased urine oxalate and calcium oxalate crystal, which lead to hematuria, proteinuria, recurrent kidney stones and nephrocalcinosis. Some patients may further progress to the AKI and CKD. With progressive decline in renal function, oxalate is reduced and deposits in the body can affect other tissues and organs. And adjustment of enteral factors is helpful for the treatment of hyperoxaluria. In this article we discuss the role of the enteric factor in the hyperoxaluria development. Hyperoxaluria is a metabolic disease characterized by excessive urinary oxalic acid excretion and calcium oxalate crystal deposition, whose intestinal factors affecting its onset includes the increased intake of oxalic acid and its precursors, the increased intestinal absorption of oxalate and the imbalance of intestinal flora, etc. Severe hyperoxaluria can lead to kidney stones. At present, the influence of intestinal factors on hyperoxaluria has become a research focus, this paper will give a comprehensive description of its related research.
