Vasculitis & polymyalgia rheumatica

Predictors for pulmonary artery involvement in Takayasu arteritis and its cluster analysis

Arthritis Res TherPublished Retrospective cohort study

Authors' conclusion

In TAK, PAI is associated with thoracic aorta involvement. In TAK patients with PAI, the involvement of the upper lobe of the right lung is characterized with the worst prognosis.

Study context

Population
Patients with TAK
Participants
141 patients
Exposure
TAK with PAI vs TAK without PAI
  • PAIn = 65
Outcome
All-cause mortality
Methodological detailsmultivariate logistic regression, cluster analysis
  • Multivariate logistic regression
  • Cluster analysis

Main finding

As reported in the abstract

Cumulative incidence of events
  • TAK with PAI had a significantly higher cumulative incidence of events than those without PAI
  • PAI vs Without PAI: P < 0.001

Observational data: associations, not effects.

Prognosis by cluster (TAK with PAI)

Cluster characterized as the upper lobe of the right lung (Cluster1) had the worst prognosis
