Secondary hyperparathyroidism (SHPT) develops frequently in patients
with "End Stage Renal Disease" because the production of 1, 25 (OH) 2-
vitamin D (calcitriol) decreases in the kidneys. That's why patients may
develop osteodystrophy or osteomalacia. The functional role of vitamin
D3 under normal body condition is to regulate secretion of parathyroid
hormone (PTH) synthesis and release. Parameters such as calcium,
phosphate and vitamin D3 act upon PTH. In normal subjects, the
homeostasis of these parameters is strongly interconnected but in renal
failure, the metabolism of each of these parameters may be deregulated.
The diseased kidney is unable to produce vital hormone that is called
erythropoietin which increases synthesis of red blood cells. The anemic
condition is seen in CKD (chronic kidney disease) because erythropoietin
production become reduced. In Pakistan, CKD patients are continuously
increasing annually. We conducted a blood and serosurvey study in Lahore
metropolitan city of Punjab, Pakistan to see the co-relation between
SHPT and CKD. This epidemiological research of public health will be
beneficial for onward broad demographic surveillance programs.
