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 manifestations at a much younger age. Clinical profile of PHPT in children is similar to that of adults.
