Abstract

Summary: To evaluate the association between haemoglobinuria and chronic kidney disease ( CKD ) in sickle cell anaemia ( SCA ), we analysed 356 adult haemoglobin SS or Sβ o thalassaemia patients from the University of Illinois at Chicago ( UIC ) and 439 from the multi‐centre Walk‐Treatment of Pulmonary Hypertension and Sickle Cell Disease with Sildenafil Therapy (Walk‐ PH a SST ) cohort. CKD was classified according to National Kidney Foundation Kidney Disease Outcomes Quality Initiatives guidelines. Haemoglobinuria, defined as positive haem on urine dipstick with absent red blood cells on microscopy, was confirmed by enzyme‐linked immunosorbent assay in a subset of patients. The prevalence of CKD was 58% in the UIC cohort and 54% in the Walk‐ PH a SST cohort, and haemoglobinuria was observed in 36% and 20% of the patients, respectively. Pathway analysis in both cohorts indicated an independent association of lactate dehydrogenase with haemoglobinuria and, in turn, independent associations of haemoglobinuria and age with CKD ( P < 0·0001). After a median of 32 months of follow‐up in the UIC cohort, haemoglobinuria was associated with progression of CKD [halving of estimated glomerular filtration rate or requirement for dialysis; Hazard ratio ( HR ) 13·9, 95% confidence interval ( CI ) 1·7–113·2, P = 0·0012] and increasing albuminuria ( HR 3·1, 95% CI : 1·3–7·7; logrank P = 0·0035). In conclusion haemoglobinuria is common in SCA and is associated with CKD , consistent with a role for intravascular haemolysis in the pathogenesis of renal dysfunction in SCA .

  • SCD patients with higher hemolysis rates have lower steady-state hemoglobin and are more likely to develop vascular injury and organ dysfunction with age, including pulmonary hypertension, diastolic left heart disease, and renal dysfunction.

    “Patients with higher rates of hemolysis have lower steady-state Hb levels and are more likely to develop vascular injury and organ dysfunction as they age, manifesting as pulmonary hypertension, diastolic left heart disease, and renal dysfunction (proteinuria, albuminuria, and chronic kidney dysfunction) (62, 64, 65, 70, 79).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
