Analgesic effect of long-acting somatostatin receptor agonist pasireotide in a patient with acromegaly and intractable headaches


A 22-year-old woman presented with worsening vision loss and headaches. A diagnosis of acromegaly was confirmed after detection of an invasive pituitary macroadenoma and biochemical testing. Despite two attempts of surgical debulking of the tumour and administration of long-acting octreotide and cabergoline, growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were uncontrolled. The patient experienced persistent headaches despite surgery, gamma knife radiation and ventriculoperitoneal shunt placement; she was then enrolled in the ACCESS trial ( identifier, NCT01995734). Pasireotide (Signifor; Signifor LAR) was initiated, which led to reduced GH and IGF-1 levels and resolution of her intractable headaches. This highlights the use of monthly pasireotide in resolving headaches and improved biochemical control in a patient with acromegaly. We postulate that the headaches improved due to an analgesic and/or anti-inflammatory effect mediated by somatostatin receptors targeted by pasireotide. This may represent an additional benefit of pasireotide and requires further investigation.
