In Brief: Herpes Zoster Vaccine (Zostavax) Revisited

The 2006 Medical Letter article on the then-new varicella-zoster vaccine concluded that Zostavax appears to be safe and effective in protecting patients ≥60 years old against herpes zoster and postherpetic neuralgia, especially in reducing the severity and duration of the disease.1 Some new information has recently become available.

CLINICAL STUDIES — A Veterans Administration randomized, double-blind trial enrolled more than 38,000 patients ≥60 years old and followed them for a mean of 3.4 years after administration of Zostavax or placebo. Since the efficacy of the vaccine had been demonstrated previously (51% in preventing zoster and 67% in preventing postherpetic neuralgia), the objective of this study was to examine its safety. Transient varicella-like rash occurred at the inoculation site in 0.11% of vaccine recipients and in 0.04% of patients who received a placebo injection. Erythema, swelling, pain and tenderness at the injection site were more frequent and more severe with the vaccine than with placebo. There were no other significant differences. Serious adverse events occurred in 1.4% of patients in each group.2

USE — Despite its efficacy and the frequency and morbidity of herpes zoster, this vaccine is hardly used. One study in 2007 found that only 2% of patients ≥60 years old had received it.3 A 2008 survey found that 7% of potential recipients had been vaccinated.4 A study of the reasons for such sparse usage concluded that the expense ($194 wholesale), the need for a freezer to store the vaccine (a vaccine that can be kept in a refrigerator is available in Europe), and reimbursement through Medicare Part D, which generally provides pharmacy benefits, rather than Part B, which physicians are more familiar with, were contributing factors.5

CONCLUSION — The efficacy of the herpes zoster vaccine (Zostavax) was well established before the FDA approved it in 2006. Several years’ use has now provided more data supporting the safety of the vaccine. It deserves wider use.

Safety of Inhaled Corticosteroids in Chronic Obstructive Pulmonary Disease (COPD)

   
The Medical Letter on Drugs and Therapeutics • May 31, 2010;  (Issue 1339)

Two combinations of an inhaled corticosteroid with an inhaled long-acting beta2-agonist are approved by the FDA for use in patients with COPD: fluticasone/salmeterol (Advair Diskus) and budesonide/formoterol (Symbicort). A Medical Letter reader has questioned the safety of using corticosteroid inhalers in patients with this disorder. No single-agent inhaled corticosteroid inhaler is approved for this indication.

Romidepsin (Istodax) for Cutaneous T-Cell Lymphoma

The FDA has approved romidepsin (Istodax – Celgene), an IV histone deacetylase (HDAC) inhibitor, for treatment of cutaneous T-cell lymphoma (CTCL) in patients who have received at least one prior systemic therapy. The most common types of CTCL are mycosis fungoides, a low-grade lymphoma usually confined to the skin, and Sézary syndrome, a more aggressive disease with malignant lymphocytes in the blood. Both can progress to fatal systemic involvement. Romidepsin is the second HDAC inhibitor approved for this indication; vorinostat (Zolinza), an oral HDAC inhibitor, was approved earlier.

Bioidentical Hormones

In recent years, many women have become concerned about the safety of pharmaceutical replacement hormones for treatment of menopausal symptoms. “Bioidentical” hormone preparations, which are not approved by the FDA, are heavily promoted in popular books and on TV as alternatives; these are derivatives of soy or plant extracts, chemically modified to be structurally identical to endogenous hormones. Most FDA-approved single-entity hormones are also derivatives of soy or plant extracts and are structurally identical to hormones produced by the ovary.
