Alarming signs and symptoms in the early diagnostics of late onset Pompe disease: super omnia clinica

Abstract

Pompe disease (PD) is a rare autosomal recessive muscle lysosomal glycogenosis caused by a deficiency of acid-α-glucosidase. There are two main forms of the disease: aggressive infantile PD started within the first year of life with a severe enzyme deficiency and multiorgan involvement, and late onset PD (LOPD) with progressive signs and symptoms including predominant proximal, axial muscle weakness and respiratory insufficiency started at any time from 1 till 75 years and older. Usually due to physician's unawareness, most adults with PD are diagnosed with great delay. The typical features and early nonspecific signs in four patients, aged between 35 and 72 years, with confirmed LOPD are delineated and discussed in correspondence with the age of first signs, age development of muscle weakness, distribution and age of final diagnosis. The disorders for differential diagnosis and spectrum of conditions that expanded the possibility of PB are listed. The fluorometrically analyzed level of acid α-glucosidase from dried blood spots is considered to be the first choice diagnostic method for clinically suspected cases of LOPD.

Lack of vigilance is the main factor of late diagnosis of glycogen storage disease type II in the Republic of Kazakhstan

“…Настороженность относительно БППН подразу-мевает обязательную оценку неспецифических симп-томов и признаков [3,9,15,16], которые могут появ-ляться в разной последовательности и усугубляться по мере развития болезни.…”

“…Анализ по сухому пятну крови -доступный, неинвазивный, информа-тивный и простой в исполнении метод, не требующий специального оборудования и больших финансовых затрат [14,[16][17][18]. В последнее время определение активности фермента АГ все чаще используется для скрининга у пациентов с подозрением на наличие БП.…”
