Prevalence of osteoporosis in patients with chronic kidney disease (stages 3–5)‎ in comparison with age-and sex-matched controls: a study from Kashmir Valley tertiary care center

الملخص EN

Chronic kidney disease (CKD) is associated with a range of metabolic bone diseases.

Fracture rates are higher in CKD patients than age-matched controls throughout all the five stages of CKD.

Dialysis patients have 4 times as many hip fractures as expected for their age.

CKD forms an independent risk factor for osteoporosis, even in the absence of traditional risk factors.

This study was carried out at the nephrology unit in a tertiary care center of Kashmir to know the prevalence of osteoporosis in CKD patients having glomerular filtration rate (GFR) <60 mL/min (stages 3–5).

Among the 151 cases studied, the average estimated GFR was 16.78 ± 10.714 mL/min.

There were 98 males (64.9%) and 53 females (35.1%).

Their mean age was 51.01 ± 14.138 years.

Osteoporosis based on femoral neck T-Score was seen in 31 patients (31.6%) while 43 patients (28.5%) had osteoporosis at L1, L2 lumbar vertebrae.

The prevalence of osteoporosis based on femoral neck T-Score as well as osteopenia was highest in stage-5 CKD.

In our study, the body mass index (BMI) had a positive correlation with osteoporosis; low BMI patients were at higher risk for osteoporosis (P = 0.014).

In the Kashmir valley, the prevalence of osteoporosis was 31.8% in CKD patients against 22% in controls.

Thus, CKD forms an important risk factor for osteoporosis even in the absence of traditional risk factors.

We recommend early screening, detection, and management of osteoporosis to reduce the burden of morbidity and mortality in this subset of patients.
