Renal cortex echogenicity increases degree of retinopathy in diabetes mellitus
Abstract: The number of people
with diabetes mellitus (DM) is increasing due to population growth, aging, and
increasing prevalence of obesity. Diabeticretinopathy and diabetic nephropathy
are two main complications of DM. Some studies suggest a correlation between
diabetic nephropathy and diabetic retinopathy. However, other studies found
that renal cortex echogenicity is associated with chronicity of kidney disease
and renalhistopathology. The aim of this study was to determine whether there
is a correlation between renal cortex echogenicity as determined by renal ultrasonography
and degree of retinopathy as determined by funduscopy in subjects with DM.
A cross sectional study was conducted on 41 DM subjects from September to
November 2014. Data obtained by anamnesis, physical examination,and examination
of ureum, creatinine, urinalysis, glycated hemoglobin (HbA1c), renal and
urinary tract ultrasonography and funduscopy, were collected from all subjects.
Blood samples were taken from the median cubital vein for biochemical
measurements using COBAS automated analyzers. Normality of data distribution
was tested using the ShapiroWilk test. To determine the relationship between
variables the Spearman correlation test was used.
Using the Spearman correlation test, a strongly significant correlation was
found between degree of renal cortex echogenicity and degree of retinopathy
(r=0.773; p=0.0001). A significant relationship was also found for the degree
of retinopathy with age (r=0.317; p=0.044), duration of diabetes mellitus
(r=0.639; p=0.0001) and HbA1c (r=0.681; p=0.001).
This study found that renal cortex echogenicity increased the degree of diabetic
retinopathy in diabetic subjects. Renal ultrasonography for patients with type
2 DM has a great role in diagnosing and grading diabeticretinopathy.
