Introduction: Primary hyperparathyroidism and vitamin D deficiency are two common conditions. Their coexistence also seems frequent and could aggravate clinical and biological manifestations of primary hyperparathyroidism. The aim of this work is to analyze the clinical and paraclinical parameters of this disease according to vitamin D status.

Methods: Retrospective study conducted at the Department of Endocrinology Diabetology and Metabolic Diseases of the University Hospital of Casablanca for a period of 4 years (2014–2018) including all patients followed up for primary hyperparathyroidism.

Results: Twenty-five patients were followed during this period for hyperparathyroidism. The average age was 56.7 years (34–76) with a clear predominance of women (84%), 77% of whom were menopausal. Vitamin D deficiency (25OHD <20 ng/ml) was present in 73% of patients. These patients had a higher PTH level with an average of 1169 pg/ml (157.3–3357) and a more frequently pathological bone densitometry.

Conclusion: In view of these results, the systematic determination of vitamin D during primary hyperparathyroidism should be done in order to better evaluate the severity of this disease and to consider possible vitamin supplementation.
