Microscopic polyangiitis can affect the lungs, causing diverse symptoms and imaging findings. Early diagnosis and tailored treatments, including novel agents, improve patient outcomes.

Area of Science:

  • Pulmonary Medicine
  • Rheumatology
  • Immunology

Background:

  • Microscopic polyangiitis is a systemic necrotizing vasculitis impacting small vessels.
  • It frequently involves organs such as the kidneys and lungs, presenting a broad clinical spectrum.
  • Pulmonary involvement presents unique diagnostic and therapeutic challenges.

Purpose of the Study:

  • To review recent advancements in understanding the pathogenesis of pulmonary microscopic polyangiitis.
  • To summarize current clinical manifestations and diagnostic approaches for lung involvement.
  • To discuss evolving treatment strategies for pulmonary manifestations.

Main Methods:

  • Literature review of recent insights and observations.
  • Analysis of clinical presentations and diagnostic imaging findings.

  • Evaluation of current and emerging therapeutic modalities.

    • Main Results:

    • Pulmonary involvement ranges from interstitial fibrosis to hemoptysis due to capillaritis.
    • CT imaging shows diverse findings like ground-glass opacities, consolidation, and honeycombing.
    • Antineutrophil cytoplasmic antibodies (ANCA) are crucial for diagnosis, pathogenesis, and prognosis.
    • Therapeutic options include cyclophosphamide, rituximab, TNF-alpha blockers, plasmapheresis, and ventilatory support.

    Conclusions:

    • Pulmonary manifestations of microscopic polyangiitis are varied and challenging.
    • Improved understanding enhances diagnostic accuracy and treatment efficacy.
    • Multidisciplinary management is key for successful patient outcomes.
