This double-blinded randomized controlled trial specifically investigated whether pericoital application of tenofovir gel prevented HSV-2 acquisition in women. This study is meaningful in buttressing the use of tenofovir vaginal gel in HSV-2 prevention programs around the world, alongside condoms and circumcision; its strength derives from its randomized, double-blinded design.
In-Depth [randomized controlled trial]: The larger study from which this was drawn was the Centre for the AIDS Programme of Research in South Africa (CAPRISA) 004 study, which involved 889 HIV-negative women in rural South Africa. 2 Minute Medicine’s The Classics in Medicine: Summaries of the Landmark Trials is available now in paperback and e-book editions. This text summarizes the key trials in: General Medicine and Chronic Disease, Cardiology, Critical and Emergent Care, Endocrinology, Gastroenterology, Hematology and Oncology, Imaging, Infectious Disease, Nephrology, Neurology, Pediatrics, Psychiatry, Pulmonology, and Surgery.
This is a viral infection of the lips and mouth which is caused by the herpes simplex virus a€“ termed HSV. Herpes doesna€™t always develop symptoms a€“ it does not always cause any outward, visible signs. Kissing or touching and any sexual contact with the area that is infected spreads oral herpes. Many individuals have symptoms of itching, burning, and tingling proceeding the outbreak of blisters or sores.
The most concentrated pain from these sores occurs at the onset and can make drinking or eating hard.
If a child with cold sores is less than 6 weeks old, the babya€™s physician needs to be notified if oral blisters or sores appear.
Individuals with weakened immunity systems should also notify their primary care physician if sores or blisters appear.
A physician will make a tentative diagnosis on data provided by the patient and on the physician exam. Topical anesthetic such as lidocaine (xylocaine, Nervocaine, Dilocaine, Zilactin-L) can be approved for pain relieve of oral blisters and lesions. Oral or IV drugs exist for HSV but only for individuals with weakened immune systems, infants younger than 6 weeks or those with severe disease.
Topical Denavir (penciclovir) creams can shorten attacks of recurrent HSV-if it is applied early, normally before lesions develop.
These medications may stop viral reproduction in the skin but do not eradicate HSV from the body or stop later outbreaks.

A 36-year-old female presented to the Emergency Treatment Center (ETC) of the University of Iowa Hospitals and Clinics (UIHC) with one day of right eye pain, photophobia and decreased vision. The following day, her symptoms did not resolve and was therefore referred to the UIHC Cornea service for further evaluation. During the first ten days of treatment, all subjective symptoms resolved with the exception of mild blurring of vision.
She returned for routine follow-up one month after discontinuation of topical corticosteroids. HSV keratitis can present with involvement of the corneal epithelium, stroma, or endothelium, with or without associated inflammation of the anterior chamber (Table 1).[1-4] Pathophysiologic manifestations may be related to the presence of live virus, immunological reactions to viral antigen, or secondary to previous herpetic injury ("metaherpetic"), particularly the loss of corneal sensation.
The diagnosis of HSV keratitis is primarily clinical, although additional tests may be useful in providing confirmation, but never exclusion.[1-4] The Tzanck (Giemsa) smear of multinucleated epithelial cells is a quick test with high specificity but low sensitivity.
HSV epithelial keratitis invariably involves active viral proliferation.[1-4] The classic epithelial dendrite is the most common presentation of epithelial disease (Figure 1). HSV stromal keratitis is associated with the highest and most severe morbidity of any ocular herpetic disease.[1-4] Although this condition frequently follows previous HSV epithelial keratitis, it can be the initial presentation of ocular herpetic disease. HSV disciform (endothelial) keratitis is a cell-mediated immune reaction to corneal endothelial tissue that presents with diffuse stromal edema.[1-4] In approximately half of cases, there is no prior history of HSV epithelial keratitis. HSV keratouveitis may occur as a separate entity or in association with herpetic epithelial, stromal, or endothelial disease.[1-4] It may be granulomatous or non-granulomatous and may, in some cases, be associated with live virus (Figure 6).
Metaherpetic manifestations of HSV keratitis include neurotrophic keratopathy and microbial (i.e. Although HSV epithelial keratitis is self-limited in most cases, the rationale for aggressive antiviral therapy is to prevent corneal nerve damage and potential future immunologic disease.[1] Prior to the advent of antiviral therapy, simple epithelial debridement was the treatment of choice.
The most common mistake in the management of HSV keratitis is premature termination of topical steroid therapy. In our clinics, the taper for stromal keratitis and keratouveitis is only one-third complete when it has been reduced to prednisolone acetate 1.0% once daily.
Our preferred steroid use and taper regimens are based upon whether or not the patient is a steroid-responder.
The introduction of oral antiviral prophylaxis constituted a major advance in the management of chronic herpetic eye disease. There are no uniformly accepted guidelines governing the use of antiviral prophylaxis in conjunction with topical corticosteroid use in situations where live viral manifestations are not present. Late surgical intervention is indicated for management of intractable corneal pain or visual impairment associated with herpetic disease.
Stromal keratitis- Acute: mid-deep stromal infiltrate with intact epithelium and minimal necrosis. Knowing how to manage these viral conditions, especially long-term, is key to saving your patients' vision.


In this double-blinded randomized controlled study, women randomized to apply intracoital vaginal tenofovir gel were significantly less likely to seroconvert to herpes simplex virus type 2 (HSV-2) compared to women who applied identical-appearing placebo gel. Tenofovir has had mixed results in preventing HIV transmission when used in a topical vaginal gel form, but has shown to reach effective concentrations for treatment of HSV-2. 422 HSV-seronegative women in rural South Africa were assigned randomly to receive either tenofovir gel or placebo gel. The greatest drawback is that the original trial was designed to assess whether tenofovir gel prevents HIV infection in women. Slit lamp photo demonstrating classic epithelial dendrites in our patient after fluorescein staining. Most cases (> 90%) are unilateral, but bilateral cases may occur, especially in atopic or immunocompromised patients.
It represents areas of epithelial breakdown due to cell destruction by proliferating virus and is best demonstrated after fluorescein staining under cobalt blue lighting.
The vast majority of cases are an immune stromal keratitis (ISK), which involves the antibody-complement cascade against retained viral antigens in the stroma. Accordingly, acute-onset, unilateral corneal edema should be considered to be due to herpetic eye disease unless proven otherwise. A guiding principle is that prior to the onset of immune-mediated disease, control and elimination of epithelial manifestations is the highest priority. Our experience is that the optimal initial frequency is hourly for NSK, every two hours for ISK, and every three hours for disciform keratitis.
In such cases, there is almost invariably a reappearance of corneal inflammation that is mislabeled as "recurrent" disease, when, in fact, it is actually a "pseudo-recurrence" that is merely a continuation of the same immunological reaction that has now become clinically apparent due to therapeutic withdrawal.
Due to the very high benefit-to-risk ratio associated with oral antiviral therapy, it is our preference to use these medications in every instance in which topical corticosteroids are utilized.
For painful eyes without visual potential, a Gunderson flap will reduce chronic inflammation and eliminate pain. Full dose oral antiviral followed by prophylactic oral antiviral (for 1 year up to indefinitely). The HSV-2 incidence rate was significantly lower among women who received tenofovir gel over a mean follow-up time of 18 months. This data was derived from a subset of those women and their tenofovir concentrations at the time of HSV-2 acquisition could not be assessed. In chronic cases, demonstration of decreased sensation by Cochet-Bonnet aesthesiometry can be helpful in differentiating true recurrent dendritic keratitis from pseudo-dendritic keratitis, especially that related to recurrent epithelial erosions. The presence of keratouveitis mandates a thorough funduscopic examination to exclude concomitant acute retinal necrosis.
However, once immune-mediated disease has been established, management of stromal or endothelial manifestations, with their potential for irreversible visual impairment, has higher priority than control of epithelial disease. However, corneal toxicity related to the topical antivirals available in the United States led to a preference on the part of many specialists to rely exclusively on equally effective systemic therapy. If concomitant epithelial disease is present, full systemic antiviral dosing is also required since steroid therapy exacerbates this condition.
For eyes with post-herpetic scarring and good visual potential, the surgical procedure is based upon the corneal pathology. Tenofovir is a nucleotide reverse-transcriptase inhibitor widely used in its oral form for antiretroviral therapy.
On Western blot confirmatory testing, there was again a significantly decreased rate of HSV-2 seroconversion among women assigned to tenofovir gel. There was, however, patchy anterior stromal inflammation in the visual axis that did not resemble the characteristic post-dendritic "footprints" and was felt to represent early immune stromal keratitis (Figure 2). On examination, the epithelium was intact but there was mild patchy anterior stromal haze in the same distribution in the visual axis as before. Bacterial and fungal cultures, along with confocal microscopy, can be used to rule out other etiologies of microbial keratitis.
Our preference is to use acyclovir 400 mg PO five times daily or valacyclovir 1000 mg PO three times daily.
Phototherapeutic keratectomy may be utilized as a keratoplasty-sparing intervention for superficial corneal scarring. While penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) are effective at re-establishing a clear cornea, eyes with herpetic indication for transplant have an elevated risk of viral reactivation within the donor tissue in the first year postoperatively. Previous research had shown that it does not provide significant protection against HIV in its topical vaginal gel form. No article should be construed as medical advice and is not intended as such by the authors or by 2 Minute Medicine, Inc. Treatment was initiated with topical prednisolone acetate 1.0% QID, while maintaining antiviral and prophylactic antibiotic coverage. There are unsubstantiated concerns that this procedure may be associated with activation of immunological stromal keratitis; in any case, perioperative use of full antiviral therapy followed by a prolonged prophylactic course obviates this issue. Research has also shown that topical application of tenofovir is associated with concentrations well above the half-maximal effective concentration for HSV-2.
There was no peripheral stromal vascularization, perineuritis, endothelial or anterior chamber inflammation. Although most practitioners prefer a short course of therapy, we treat our patients for a total of 14 to 21 days to ensure complete eradication of replicating organisms.


For deeper stromal scarring, penetrating or deep anterior lamellar keratoplasty are the procedures of choice. After successful treatment, therapy can be discontinued without tapering, unless long-term prophylaxis is used (see below; antiviral prophylaxis). The prognosis for graft survival has improved dramatically over the last quarter century since the introduction of oral antiviral prophylaxis.
The Vagaries of Vaccines: Did Varivax Create a Shingles Boom?We eye care providers focus our attention on zoster-based disease presentations in adulthood, as this is how it presents in our offices. This can be attributed to reduced recurrence of herpetic epithelial keratitis, a condition that is frequently associated with acute endothelial rejection episodes. These results were minimally affected by adjustment for confounding factors including age, parity, use or nonuse of hormonal contraception, and living or not living with a regular partner. Neither ISK nor NIK is self-limited and failure to provide appropriate pharmaceutical intervention will result in progressive corneal scarring and visual impairment. In the unusual situation of corneal endothelial decompensation due to neglected or recalcitrant endothelial keratitis, endothelial keratoplasty can be performed if stromal disease has not been present. Notably, these relationships were disrupted by the widespread varicella vaccination process begun two decades ago when Varivax (Merck) was added to the recommended childhood vaccination schedule in 1995.
The virus type is more easily contained by the immune system, which reduces disease burden. The Oka strain is more easily contained by the immune system, preventing initial manifestation of chicken pox, and more easily held in latency, which theoretically should reduce zoster incidence in adulthood among those vaccinated.
However, patients who are at risk for shingles and in the absence of an immediate history of the disease should likely be encouraged to receive the booster.
Herpes simplex and herpes zoster both begin as epithelial disease; however, once established as affecting the cornea, HSV may vacillate freely between epithelial recurrences of infection and immune stromal keratitis as well as iridocyclitis, and may have a tendency towards frequent recurrences. This is in contrast to zoster ophthalmicus, which progresses more typically on a temporal continuum, with some cases resolving early in the process and others progressing to chronic smoldering ocular inflammation. Therefore, while the management of HSV keratitis involves episodic treatments of acute flare-ups, zoster keratitis, while less common, can sometimes take months to effectively clear and may be marked by periodic manifestations of different forms of the disease. Suppression dosing of acyclovir reduces the risk of recurrence of epithelial and stromal keratitis by approximately 50%, though this effect is not as robust in patients without a history of previous stromal keratitis.3.
Topical corticosteroids are safe and effective in treating herpetic stromal keratitis and iridocyclitis.
The generally accepted mechanism of these keratitides is that dendritic disease is actually infectious keratitis characterized by proliferation of live virus within the epithelial margins of the lesion, while stromal and endothelial effects are inflammatory responses to retained non-vital viral proteins. As such, it’s useful to sub-classify HSV keratitis as infectious epithelial keratitis or immune stromal keratitis and treat as the underlying mechanism indicates. For infectious epithelial disease, an antiviral (either oral or topical) is sufficient.18 For immune stromal disease, topical steroids and a paired prophylactic topical or oral antiviral is appropriate treatment. Research shows either approach to be equivalent.14 When the pathology moves deeper, though, I become more particular about treatment regimens. In cases of inflammatory sub-dendritic, nummular or disciform keratitis, I use a topical corticosteroid paired with an oral antiviral for prophylaxis, as effective penetration of the topically dosed antivirals becomes a concern. This distinction is illustrated by the differences in prescribing practices in the treatment of non-ocular disease of both HSV and VZV. Also, as HZO often progresses along many months, it’s important to realize that dosing of steroids may require a several month taper. In cases of anterior uveitis, the most common causative systemic etiologies are: idiopathic, HLA-B27 associated disease, sarcoidosis and herpetic disease. Of this group, new diagnoses decrease significantly in patients over age 60 for all causes except herpetic disease, as most cases of autoimmune disease develop and are established prior to age 60. Understanding these subtleties and recognizing the differences between HSV and VZV can improve practitioner confidence and patient care, and lead to better outcomes.
