This could be secondary to physicians not strongly recommending the vaccine, not stocking the vaccine for easy accessibility, or upfront costs to the physician.7,10 == Herpes Simplex Virus == The herpes simplex virus (HSV) is pervasive worldwide, affecting approximately 536 million people aged 15 to 49 in 2003. 12 months in the United States, with a lifetime risk of approximately 1 in 3.24One population-based study determined that 68 Leuprorelin Acetate percent of herpes zoster occurred in persons aged 50 and older, with the incidence increasing one percent yearly in those 75 and older.4The most common complication of zoster in healthy individuals is postherpetic neuralgia (PHN), defined as persistent pain for 30 days or more after the skin disease has resolved.1PHN occurs in 18 percent of affected adults. Incidence is usually five percent in those less than 60 years of age, but raises to 10 percent in those 60 to 69 years of age and to 20 percent in those 80 years of age or older.4 Zostavax. Zostavax (Merck & Co., Inc) is a live attenuated vaccine approved by the United States Food and Drug Administration (FDA) in 2006 for adults 60 years of age and older, with revised approval in 2011 for adults 50 years of age and older.2,5,6Administered as a single subcutaneous injection as a means to prevent or minimize zoster, Zostavax is usually indicated for healthy individuals with a known history of varicella.5If a prior history YM-53601 of chickenpox is unknown, serological testing should be completed.5The vaccine is comparable to Varivax (Merck & Co., Inc), the varicella vaccine, but is usually 14 times more potent. Cost can be appreciable (i.e., $200$400) and may not be covered by insurance.7 In the Shingles Prevention Study, Zostavax reduced the incidence of herpes zoster by 51.3 percent, the burden of illness secondary to herpes zoster by 61.1 percent, and the incidence of PHN by 66.5 percent.2The most common adverse effects were injection site reactions of erythema, pain or tenderness, swelling, and pruritus.2After 3.4 years, rates of hospitalization or death did not differ between those YM-53601 who received the vaccine and control groups.8 The personal impact of herpes zoster and PHN can be significant; 64 percent of patients experience sleep disturbance, 58 percent decreased enjoyment of life, and 53 percent alteration in general activities, the latter extending for 27 to 30 days in one study.9Physicians should encourage the use of Zostavax YM-53601 as program vaccination for healthy individuals 50 years and older. Regrettably, of the adults that should receive the vaccine, less than 10 percent do so. This could be secondary to physicians not strongly recommending the vaccine, not stocking the vaccine for easy accessibility, or upfront costs to the physician.7,10 == Herpes Simplex Virus == The herpes simplex virus (HSV) is pervasive worldwide, affecting approximately 536 million people aged YM-53601 15 to 49 in 2003. Women are infected more often, and infection rates increase with age in both men and women.11Prevention is the mainstay of treatment and many new products are in development. PRO 2000, SAMMA. Topical microbicides include PRO 2000, cellulose sulfate, and polystyrene, all sulfonated polysaccharides that form complexes with glycoprotein B to inhibit HSV from binding, penetrating, and spreading between cells.12,13These microbicides are applied intravaginally before sexual intercourse and,in vitro, inhibit HSV infection 10,000-fold.12Human trials have shown that PRO 2000 gel (Indevus), a synthetic naphthalene sulfonic acid polymer, inhibits human immunodeficiency virus (HIV) and HSV by at least 1,000-fold.14 SAMMA, a mandelic acid condensation polymer, targets glycoprotein B-2, but does not contain sulfur.15In vitroSAMMA blocks the binding of HIV and HSV and has shown activity againstNeisseria gonorrhoeaeandChlamydia trachomatis.15 Invisible condom. The invisible condom is yet another microbicide, a polyoxyethylene-polyocypropylene block copolymer that is in Phase 2/3 trials.16It is safe to use in healthy women once or twice daily for 14 days as well as their male sexual partners. Common adverse reactions were erythema (27%), itching (56%), dryness (34%), and burning (29%).17 Glycoprotein D vaccine. Glycoprotein D vaccine, administered intramuscularly at 0, 1,.
