“…Osteoclasts have been detected in many different GSD patient samples ( Pazzaglia et al, 1997 ; Avelar et al, 2010 ; Bruder et al, 2009 ; Choma et al, 1987 ; Hammer et al, 2005 ; Hirayama et al, 2001 ; Lehmann et al, 2009 ; Möller et al, 1999 ; Silva, 2011 ; Spieth et al, 1997 ; Poirier, 1968 ; Jones et al, 1958 ) and CTX-1 has been reported to be elevated in several patients ( Liu et al, 2016 ). Zoledronic acid has been given to GSD patients in an attempt to prevent bone loss ( Avelar et al, 2010 ; Hagendoorn et al, 2006 ; Kuriyama et al, 2010 ; Leite et al, 2013 ; Ruggieri et al, 2011 ; Gem et al, 2014 ; Mignogna et al, 2005 ; Yerganyan et al, 2015 ). Indeed, several case reports state that there is no further progression of the disease after the patient is treated with zoledronic acid ( Avelar et al, 2010 ; Kuriyama et al, 2010 ; Gem et al, 2014 ; Mignogna et al, 2005 ; Yerganyan et al, 2015 ).…”
