Recurrent Priapism From Cabergoline and Bromocriptine in a Hypogonadal Man With Prolactinoma.

Dopamine agonists are generally well tolerated and represent the first-line therapy for prolactinomas. We report a case of a 20-year-old man with a macroprolactinoma who developed recurrent priapism with cabergoline and bromocriptine. Transsphenoidal pituitary adenoma resection was done with normalization of the prolactin level. Priapism is a rare side effect of dopamine agonists that warrants discontinuation of therapy. Patients should be educated about this potential side effect at the time of prescribing the medication.

Atezolizumab-induced type 1 diabetes mellitus in a patient with metastatic renal cell carcinoma.

Checkpoint inhibitor immunotherapy has revolutionised cancer treatment since its inception. During an inflammatory response, activated cytotoxic T cells expressing programmed cell death protein 1 (PD-1) interact with programmed cell death-ligand 1 (PD-L1) on peripheral tissues to thwart an autoimmune reaction. Cancer cells upregulate PD-L1 expression to evade the immune system and are vulnerable to attack in the presence of PD-1 or PD-L1 checkpoint inhibitors. However, blockade of this pathway also contributes to the unintended side effect of autoimmune endocrinopathies. Atezolizumab, a checkpoint inhibitor against PD-L1, is associated with the rare complication of type 1 diabetes. We present a case of glutamic acid decarboxylase antibody-positive type 1 diabetes developing in a patient with a long-standing history of well-controlled type 2 diabetes following treatment with atezolizumab for metastatic renal cell carcinoma.

Pharmacoeconomic evaluation of sodium-glucose transporter-2 (SGLT2) inhibitors for the treatment of type 2 diabetes.

INTRODUCTION: Clinicians have many safe and effective options for the treatment of type 2 diabetes that can improve glycemic control and effect other cardio-metabolic parameters. Sodium-glucose transporter-2 inhibitors (SGLT-2) are the most recent class of therapies, have a novel mechanism of action, and provide good glycemic efficacy and a favorable cardiovascular risk profile. Cost-effectiveness data can play an important role in assessing the benefits of this class of therapy in anti-diabetes treatment regimens. Areas covered: This review summarizes all the available evidence regarding the cost-effectiveness of SGLT-2 inhibitors. For the purposes of this article, the authors have performed a systematic review of pharmacoeconomic analyses through a non-restricted literature until June 2018. Expert opinion: The available analyses demonstrate that SGLT-2 inhibitors are a more cost-effective option compared to other oral anti-diabetes therapies and insulin in the treatment of individuals with uncontrolled type 2 diabetes. Future studies should examine populations with renal and liver disease and expand data of some SGLT-2 inhibitors to patients at high cardiovascular risk and hard endpoint data.
