Primary hyperoxaluria type 1: practical and ethical issues

Primary hyperoxaluria type 1 (PH1) is a rare inborn error of glyoxylate metabolism of autosomal recessive inheritance, leading to progressive systemic oxalate storage (named 'oxalosis') with a high rate of morbidity and mortality, as well as an unacceptable quality of life for most patients. The adverse outcome, however, is partly due to issues that can be overcome. First, the diagnosis of PH is often delayed due to a general lack of knowledge of the disease among physicians. This accounts specifically for patients with pyridoxine sensitive PH, a group that is paradoxically most easy to treat. Second, lack of adherence to a strict conduction of conservative treatment and optimal urological management may enhance an adverse outcome of the disease. Third, specific techniques to establish PH1 and specific therapies are currently often not available in several low-resources countries with a high prevalence of PH. The management of patients with advanced disease is extremely difficult and warrants a tailor-made approach in most cases. Comprehensive programs for education of local physicians, installation of national centers of expertise, European support of low-resources countries for the management of PH patients and intensified international collaboration on the management of current patients, as well as on conduction of clinical studies, may further improve outcome of PH.
