An outbreak of mumps has occurred among students at Fordham University in New York. All of those who developed mumps had been vaccinated against the disease.

One of our readers has suggested that more attention should have been paid to a study comparing the antiplatelet effects of immediate-release and enteric-coated aspirin that appeared in Circulation last year.1 The safety benefits of enteric-coated aspirin are unclear. It may protect against dyspepsia, but not against major gastrointestinal bleeding, which is thought to be mainly a systemic effect of prostaglandin inhibition.ANTIPLATELET EFFECTS OF ASPIRIN — Aspirin irreversibly acetylates cyclooxygenase-1, blocking thromboxane synthesis and inhibiting platelet activation and aggregation for...

Some readers of our article on Antiviral Drugs for Seasonal Influenza have expressed concerns regarding our recommendation for use of the oral neuraminidase inhibitor oseltamivir (Tamiflu) to treat high-risk patients with confirmed or suspected influenza illness, citing the British Medical Journal and The Cochrane Collaboration, which have contended that there is no acceptable evidence that the drug prevents complications or hospitalizations and have questioned the completeness of the results of controlled trials conducted by the manufacturer (Roche).

The FDA has approved an IV formulation of the antifungal drug posaconazole (Noxafil - Merck) for prophylaxis of Aspergillus and Candida infections in adults at high risk for these infections, such as those with prolonged neutropenia. Posaconazole is also available as delayed-release tablets and an oral suspension.With activity against Aspergillus and Candida, posaconazole has an antifungal spectrum similar to that of voriconazole (Vfend, and generics), but unlike voriconazole it is also active against many species of Mucorales (formerly called Zygomycetes), such as Mucor and Rhizopus....

The FDA recently announced changes in the labeling of the hepatitis C drugs Sovaldi (sofosbuvir) and Harvoni (sofosbuvir/ledipasvir) to warn about a risk of serious and potentially fatal bradycardia when either drug is taken with the antiarrhythmic drug amiodarone (Cordarone, and others).1 Symptomatic bradycardia was reported following initiation of treatment with Harvoni or with Sovaldi plus simeprevir (Olysio) or the investigational antiviral drug daclatasvir in 9 patients already taking amiodarone; it occurred within 24 hours of starting hepatitis C therapy in 6 patients and within 2-12...

The FDA has approved the Bruton tyrosine kinase (BTK) inhibitor acalabrutinib (Calquence – AstraZeneca) for oral treatment of relapsed or refractory mantle cell lymphoma. Acalabrutinib is the second BTK inhibitor to be approved for this indication; ibrutinib (Imbruvica) was approved in 2013.Ibrutinib inhibits other kinases in addition to BTK and has been associated with severe adverse effects, particularly atrial fibrillation, infection, rash, and bleeding, that may be related to inhibition of kinases other than BTK.1 Acalabrutinib is a more selective BTK inhibitor than ibrutinib; whether...

On May 10, 2021, the FDA expanded its Emergency Use Authorization (EUA) for the Pfizer/BioNTech mRNA-based COVID-19 vaccine to include adolescents 12-15 years old.1The vaccine has been authorized for use in persons ≥16 years old since December 2020.

On July 12, 2021, the FDA added a warning to the Fact Sheet for the Johnson & Johnson (Janssen) adenovirus-based COVID-19 vaccine about an increased risk of Guillain-Barré syndrome (GBS) following administration of the product.

The FDA has approved Merilog (Sanofi), a biosimilar to rapid-acting insulin aspart (NovoLog), for treatment of patients with type 1 or type 2 diabetes. Merilog is the first rapid-acting insulin biosimilar product to become available in the US.

The FDA has authorized use of the Visby Medical Women's Sexual Health Test (Visby), an at-home test available without a prescription, for detection of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infections in women with and without symptoms. It is the first test to become available in the US for these sexually transmitted infections (STIs) that can be performed entirely at home. Other at-home tests are available in the US for diagnosis of chlamydia, gonorrhea, and trichomoniaisis, but they require mailing a urine or blood sample to a...
