NCT03250000

Brief Summary

This study investigates the influence of acute exacerbation of chronic obstructive pulmonary disease (COPD) on retinal microcirculation, on functional status and also investigates the prognostic value of retinal vessel caliber assessment in terms of hospitalization and mortality during 2 years of follow-up.

Outcome Measures

Primary Outcomes (2)

  • Changes in Retinal microcirculation

    Fundus of the right eye will be photographed using a retinal camera. The vessel diameters had geometric patterns will be measure.

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

  • Changes in Functional status tests

    Short physical performance battery (SPPB), which consists of a four meter gait test, a five-repetition sit-to-stand test and a balance test will be done. All the testes ranged from 0 to 4 and the sum of the three components comprised the final SPPB score, with a possible range from 0 to 12.

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

Secondary Outcomes (11)

  • Functional exercise tolerance

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

  • Muscle Function

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

  • Changes in Daily physical activity

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

  • Impact of the disease

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

  • Impact of the dyspnea

    Stable: Outpatient clinic/ COPD exacerbated: Day 2-3 in hospital; Day 5-7 in hospital; 4 weeks after discharge

  • +6 more secondary outcomes

Study Arms (2)

COPD-Ex

Patients admitted to the respiratory ward of ZOL Genk with a diagnosis of acute exacerbation, based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria.
