Real-world evidence concerning clinical and economic outcomes of switching to insulin glargine 300 units/mL vs other basal insulins in patients with type 2 diabetes using basal insulin.

This retrospective cohort study compared real-world clinical and healthcare-resource utilization (HCRU) data in patients with type 2 diabetes using basal insulin (BI) who switched to insulin glargine 300 units/mL (Gla-300) or another BI. Data from the Predictive Health Intelligence Environment database 12 months before (baseline) and 6 months after (follow-up) the switch date (index date, March 1, 2015 to May 31, 2016) included glycated haemoglobin A1c (HbA1c), hypoglycaemia, HCRU and associated costs. Baseline characteristics were balanced using propensity score matching. Change in HbA1c from baseline was similar in both matched cohorts (n = 1819 in each). Hypoglycaemia incidence and adjusted event rate were significantly lower with Gla-300. Patients switching to Gla-300 had a significantly lower incidence of HCRU related to hypoglycaemia. All-cause and diabetes-related hospitalization and emergency-department HCRU were also favourable for Gla-300. Lower HCRU translated to lower costs in patients using Gla-300. In this real-world study, switching to Gla-300 reduced the risk of hypoglycaemia in patients with type 2 diabetes when compared with those switching to another BI, resulting in less HCRU and potential savings of associated costs.

Idiopathic hypoparathyroidism presenting with severe hypocalcemia and asymptomatic basal ganglia calcification followed by acute intracerebral bleed.

OBJECTIVE: To report a case of idiopathic hypoparathyroidism presenting with severe hypocalcemia and intracerebral calcifications that resulted in a spontaneous intracerebral bleed. METHODS: We present the clinical, laboratory, and radiologic findings in a woman with idiopathic hypoparathyroidism who developed spontaneous intracerebral bleed in the setting of chronic intracerebral calcifications. RESULTS: A 37-year-old woman presented with vague symptoms of hypocalcemia. Clinical evaluation revealed brisk deep tendon reflexes and positive Chvostek's and Trousseau's signs. The serum calcium level was 3.7 mg/dL (reference range, 8.0 to 10.6 mg/dL) and the phosphorus level was 8.2 mg/dL (reference range, 2.3 to 5.0 mg/dL). Serum intact parathyroid hormone was undetectable. Computed tomography of the head showed extensive bilateral symmetrical calcification of basal ganglia and dentate nucleus in the cerebellum and centrum semiovale. Fluid and electrolytes were replaced appropriately, and calcium and calcitriol were prescribed. While in the hospital, the patient developed an acute intracerebral bleed confirmed by computed tomography. The patient recovered without neurologic sequelae and was discharged from the hospital on calcium supplementation and calcitriol. Repeated computed tomography of the head 3 years later demonstrated complete resolution of the bleed. CONCLUSION: This case suggests that patients with severe hypoparathyroidism and intracerebral calcification may be at risk for spontaneous intracerebral bleed and should be monitored accordingly.
