Summary

HIV infection and antiretroviral therapy can cause mitochondrial damage, leading to neuromuscular disorders like distal symmetric polyneuropathy and myopathy. These conditions involve both mitochondrial and immune system mechanisms.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Mitochondrial Biology

Background:

  • Neuromuscular syndromes are common in HIV-infected patients.
  • Mitochondrial dysfunction is increasingly recognized as a key factor in HIV-related neuromuscular pathology.
  • Antiretroviral (ARV) therapy may contribute to mitochondrial damage.

Purpose of the Study:

  • To review current evidence on mitochondrial pathology in HIV-associated neuromuscular disorders.
  • To discuss the role of mitochondria in distal symmetric polyneuropathy (DSP), myopathy, and HIV-associated neuromuscular weakness syndrome (HANWS).

Main Methods:

  • Literature review of studies investigating mitochondrial dysfunction in HIV and ARV therapy.
  • Analysis of in-vivo data for specific neuromuscular syndromes.

Main Results:

  • Myopathy shows the most substantial in-vivo evidence linking it to HIV-related mitochondrial pathology.
  • Distal symmetric polyneuropathy (DSP) and HIV-associated neuromuscular weakness syndrome (HANWS) also exhibit growing evidence of mitochondrial involvement, especially with ARV use.

Conclusions:

  • HIV infection and ARV therapy contribute to neuromuscular disorders through mitochondrial-mediated pathology.
  • These conditions likely arise from a complex interplay of mitochondrial dysfunction and immunological responses.
  • Further research is needed to fully elucidate the mechanisms and develop targeted treatments.
