Abstract(s)
A qualidade muscular foi recentemente associada à sarcopenia. No entanto, já é reconhecida como um critério que pode confirmar a presença de sarcopenia e de obesidade sarcopénica. O objetivo desta revisão da literatura é apresentar uma visão geral atualizada quanto às evidências atuais sobre a qualidade muscular como um critério de diagnóstico para a sarcopenia e obesidade sarcopénica.
A PubMed foi a base de dados eleita para a procura de evidência onde foram aplicados os seguintes critérios de inclusão: artigos desde 2010; em humanos; com idioma em português, inglês ou espanhol.
A qualidade muscular é essencial para a função muscular especialmente com o avanço da idade. A deterioração da qualidade muscular pode preceder a perda de massa muscular, portanto, a avaliação desse parâmetro pode ser benéfica para a identificação precoce de sarcopenia ou obesidade sarcopénica.
Embora a qualidade muscular tenha o potencial de ser um critério relevante no diagnóstico dessas condições, apresenta algumas limitações, como o recurso a ferramentas sofisticadas e de acesso limitado, alto custo, exposição à radiação e necessidade de profissionais altamente qualificados, o que prejudica a aplicação mais ampla dessas técnicas na prática clínica.
Em conclusão, a avaliação da qualidade muscular é um parâmetro promissor para o diagnóstico de sarcopenia e obesidade sarcopénica, principalmente em estádios iniciais. Porém, mais estudos são necessários relativamente à qualidade muscular como critério diagnóstico para sarcopenia e obesidade sarcopénica, uma vez que ainda não existe um método adequado para a aplicação por rotina na prática clínica.
Muscle quality has been recently associated with sarcopenia. However, it is already recognized as a criterion that can confirm the presence of sarcopenia and also sarcopenic obesity. The purpose of this literature review is to present an updated overview on the current evidence regarding muscle quality as a diagnostic criterion for sarcopenia and sarcopenic obesity. PubMed was the database elected for the search of evidence and the following inclusion criteria were applied: articles since 2010; in humans; with language in Portuguese, English or Spanish. Muscle quality is vital to muscle function later in life and it actually decreases with age. The deterioration of muscle quality may precede the loss of muscle mass, therefore the assessment of this parameter can be beneficial for early identification of sarcopenia or sarcopenic obesity. Even though muscle quality has the potential to be a relevant criterion in the diagnosis of this conditions, it presents some limitations such as the need for sophisticated tools that are of limited access, besides high cost, exposure to radiation and the need for highly qualified professionals, which impairs the wider use of these techniques in clinical practice. In conclusion, muscle quality assessment is a promisor parameter for the diagnosis of sarcopenia and sarcopenic obesity, particularly in early stages of these conditions. However, more research is needed concerning muscle quality as a diagnostic criterion for sarcopenia and sarcopenic obesity, since there is still no suitable method for routine use in clinical practice.
