Intriguing association between type 1 diabetes mellitus, Gitelman syndrome and Cacci-Ricci disease: Triad of rare diseases: A case report.

ABSTRACT

We report the case of a patient who exhibits a concurrent diagnosis of type 1 diabetes mellitus, Gitelman syndrome and Cacci-Ricci disease. A 27-year-old male patient was diagnosed with Gitelman syndrome at the age of 3 years. Fourteen years later, he developed an autoantibody-negative type 1 diabetes mellitus. Cacci-Ricci's disease was revealed by terminal hematuria and considered in view of the appearance found on the computed tomography (CT) scan. The finger-prick blood glucose level was 6 g/dl with no acetonuria. Creatinine clearance was 60 ml/min. Thyroid function tests were normal. Calcium, phosphorus and parathormone (PTH) levels were normal. Discussion: Gitelman syndrome is a rare disorder. The association between Gitelman syndrome and type 1 diabetes mellitus has been reported in the literature in two patients. Authors have investigated the association between Gitelman syndrome and type 2 diabetes mellitus. Several pathophysiological explanations have been put forward. Cacci-ricci disease is a rare, benign congenital anomaly. No association between type 1 diabetes mellitus, Gitelman syndrome and Cacci-Ricci disease has been reported in the literature. To our knowledge, this is the first case described in the literature.
