A recent advertisement for the proton pump inhibitor (PPI) lansoprazole (Prevacid - TAP) suggests that children who cough at night, complain of abdominal pain, refuse to eat, or have a bad taste in their mouths may all have gastroesophageal reflux disease (GERD). A Bunny's Tummy Trouble, a children's book about GERD published by TAP, is now available as a patient handout in pediatricians' waiting rooms. The use of acid-suppressive drugs in infants and children has increased markedly in recent years and many of these drugs are now available in child-friendly formulations. A table in the article...

Sunitinib (Sutent - Pfizer) and sorafenib (Nexavar - Bayer), two oral tyrosine kinase inhibitors, have been approved by the FDA for treatment of advanced renal cell carcinoma (RCC). Sunitinib is also approved for use in patients with gastrointestinal stromal tumor (GIST) who are not responding to or are intolerant of standard therapy with imatinib (Gleevec).

Natalizumab (Tysabri - Elan and Biogen) is a monoclonal antibody approved for induction and maintenance treatment of moderate to severe Crohn's disease (CD) refractory to conventional therapies and inhibitors of tumor necrosis factor (TNF). Initially approved in 2004 for the treatment of multiple sclerosis (MS), natalizumab was temporarily withdrawn from the market after 3 patients developed progressive multifocal leukoencephalopathy (PML). It is now available for treatment of both MS and CD through a restricted distribution program.

Golimumab (Simponi - Centocor), a fully humanized anti-tumor necrosis factor (TNF)-a antibody, has been approved by the FDA for the treatment of: (1) moderate to severe active rheumatoid arthritis (RA) in combination with methotrexate; (2) active psoriatic arthritis (PsA) alone or in combination with methotrexate; and (3) active ankylosing spondylitis (AS).

The injectable interleukin (IL)-23 antagonist risankizumab-rzaa (Skyrizi – Abbvie) has been approved by the FDA for treatment of moderately to severely active Crohn's disease (CD) in adults. Risankizumab was approved earlier for treatment of plaque psoriasis and psoriatic arthritis.

Standard approaches to therapy for gastroesophageal reflux disease (GERD) include lifestyle changes, over-the-counter and prescription drugs, and sometimes surgery. Emerging endoscopic anti-reflux procedures that are less invasive than surgery are potential additions to current treatment options. An endoscopicallyguided radiofrequency (RF) energy delivery system, Stretta (Curon Medical), was approved by the FDA for treatment of GERD in 2000.

Sitagliptin phosphate (Januvia - Merck) is the first dipeptidyl-peptidase-4 (DPP-4) inhibitor to be marketed for treatment of type 2 diabetes. It has been approved by the FDA for oral use as monotherapy or in combination with metformin (Glucophage, and others), pioglitazone (Actos) or rosiglitazone (Avandia).

A variety of glucose monitoring devices have been used in an effort to reduce the hypoglycemia and wide glucose excursions that complicate insulin treatment of diabetes. Since the last Medical Letter issue reviewing such devices, more continuous glucose monitoring (CGM) systems have become available. Five devices available now, and two expected to be marketed soon, are listed in the table on page 14. The FDA has approved continuous glucose devices only for the observation of glucose trends.

The FDA has approved the interleukin (IL)-23 antagonist risankizumab-rzaa (Skyrizi – Abbvie) for treatment of moderate to severe plaque psoriasis in adults. Risankizumab is the third IL-23 antagonist to be approved for this indication; guselkumab (Tremfya) and tildrakizumab (Ilumya) were approved earlier.
