NCT06409624 | Active Not Recruiting DMC

• 1 other identifier: AZ174/18
• Study Type: observational
• Target: 350
• Locations: 1 country
• Sites: 1

Brief Summary

The objective of this study is to examine the association between urinary and plasma biomarkers and change in estimated glomerular filtration rate (eGFR) among patients with pulmonary hypertension (PH).

Conditions

Pulmonary Hypertension; Chronic Kidney Disease

Outcome Measures

Primary Outcomes (1)

• Major adverse kidney events

  Number of patients experiencing ≥q of the individual outcomes of the composite outcome of eGFR decline ≥25%, initiation of dialysis, or all-cause mortality

  Baseline to 12 months

Secondary Outcomes (3)

• Initiation of dialysis

  Baseline to 12 months

• All-cause mortality

  Baseline to 12 months

• Kidney function decline

  12 months

Other Outcomes (1)

• Worsening PH

  Baseline to 12 months

Study Arms (2)

Pulmonary hypertension

Patients with diagnosed PH by right heart catheterization with or without PH-specific treatment

Other: No intervention is planned as part of the study

No pulmonary hypertension

Patients in whom PH was excluded by right heart catheterization

Other: No intervention is planned as part of the study

Interventions

No intervention is planned as part of the study OTHER

No intervention is planned as part of the study

No pulmonary hypertension; Pulmonary hypertension

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Inpatients admitted at University Hospital Giessen and Marburg, Campus Giessen with suspected or pre-diagnosed PH undergoing RHC

You may qualify if:

• Inpatients aged ≥18 years
• Undergoing right heart catheterization (RHC)

You may not qualify if:

• Active tumor disease requiring targeted therapy
• inflammatory or autoimmune disease with renal involvement requiring systemic immunosuppressive treatment
• unexplained kidney function decline, defined as serum creatinine increase ≥0.5 mg/dL from baseline within the prior 7 days before RHC
• Chronic kidney disease with eGFR \<20 ml/min/1.73 m2
• non-kidney failure requiring extracorporeal or peritoneal ultrafiltration for diuretic-resistant volume overload
• if they had received non-steroidal anti-inflammatory drugs or intravenous contrast within 72 hours before RHC
• prediagnosed glomerulonephritis
• polycystic kidney disease
• postrenal obstruction
• single kidney (functional or anatomical)
• solid organ transplantation
• anticipated life expectancy of \<12 months
• likelihood of receiving advanced therapy (mechanical circulatory assist device/lung or cardiac transplant)
• pregnancy or possibility of pregnancy in the next 12 months
• inability to cooperate with respiratory maneuvers during renal Doppler
