Clinical profile of primary hyperparathyroidism from western India: A single center experience

Background: Primary hyperparathyroidism (PHPT) has a variable clinical presentation and symptomatic PHPT is still the predominant form of the disease in India. Data from western India is lacking.
Aim : To present the clinical profile of PHPT from western India.
Settings and Design : This retrospective study was conducted at a tertiary care referral center.
Materials and Methods : We analyzed the clinical presentation, biochemical, radiological features, and operative findings in adult patients with PHPT (1986-2008) and compared with our published data of children and adolescent patients with PHPT.
Statistical Analysis : was done with SPSS 16 software.
Results : Seventy-nine patients (F: M-2:1) with age ranging from 21 to 55 years (mean 33.5±8.82) were analyzed. Skeletal manifestations (75.5%), renal calculi (40.5%) and proximal muscle weakness (45.5%) were the most common symptoms of presentation with mean duration of symptoms being 33.70 (median: 24, range 1-120) months. Biochemical features included hypercalcemia (total corrected calcium 12.55±1.77 mg/dl), low inorganic phosphorus (1.81±0.682 mg/dl), elevated total alkaline phosphatase (mean: 762.2; median: 559; range: 50-4930IU/L) and high parathyroid hormone (PTH) (mean±SD: 866.61±799.15; median: 639.5; range: 52-3820 pg/ml). Preoperative localization was achieved in 74 patients and single adenoma was found during surgery in 72 patients. Hungry bone disease was seen in 30.3% and transient hypoparathyroidism developed in 62% patients. In comparison to PHPT in children there were no significant differences with regard to clinical, laboratory and radiological features.
Conclusions : PHPT in western India is symptomatic disorder with skeletal and renal mani-festations at a much younger age. Clinical profile of PHPT in children is similar to that of adults.
