Hypophosphatasia is a recessively inherited disorder with a wide phenotypic manifestation ranging from lethality in neonates to asymptomatic in adults. The severity of the phenotype is largely determined by the nature of the ALPL mutations. We describe a previously asymptomatic adult whose phenotype dramatically changed after he developed renal failure. A 50-year-old man was diagnosed with IgA nephropathy. At age 52 (eGFR 50 ml/min) he suffered his first metatarsal fr...

Background: In patients with gout, urate deposition has been observed both adjacent to and within tendons, suggesting that monosodium urate monohydrate (MSU) crystals are likely to be in direct contact with tenocytes, the stromal cells of tendons. The aim of this study was to determine the effects of MSU crystals on tenocyte viability and function.Methods: Cultures of primary rat tenocytes were prepared from Wistar rat tails. Primary human tenocytes were...
