What are the treatment guidelines for herpetic keratoconjunctivitis (Herpes Simplex Keratitis)?

From the Guidelines

Treatment of herpetic whitlow, also known as herpetic keratoconjunctivitis, involves antiviral medications and supportive care, with oral acyclovir 400 mg five times daily for 7-10 days being a common treatment approach, as seen in the context of herpes simplex virus conjunctivitis 1. The goal of treatment is to reduce viral replication, alleviate symptoms, and prevent complications.

• Antiviral medications such as acyclovir, valacyclovir, and famciclovir are effective in treating herpetic whitlow by inhibiting viral DNA synthesis.
• Supportive care includes keeping the affected area clean and dry, avoiding bandages that trap moisture, taking pain relievers as needed, and elevating the affected area to reduce swelling.
• Topical antiviral treatments like ganciclovir 0.15% gel or trifluridine 1% solution may be used in conjunction with oral antivirals for cases with concomitant corneal involvement, as suggested by the conjunctivitis preferred practice pattern 1.
• It is essential to avoid touching or breaking vesicles to prevent secondary bacterial infection and viral spread, and warm compresses can provide symptomatic relief.
• Patients should be advised that recurrences are possible, especially in the first year after initial infection, and to seek treatment promptly if symptoms return, highlighting the importance of follow-up visits within 1 week of treatment, including an interval history, visual acuity measurement, and slit-lamp biomicroscopy 1.

From the Research

Treatment Guidelines for Herpetic Whitlow

• Herpetic whitlow is a painful cutaneous infection caused by herpes simplex virus (HSV) types 1 or 2, and its treatment involves the use of antiviral agents such as acyclovir 2.
• Acyclovir has been used to treat herpetic whitlow, although controlled studies on its efficacy for this specific condition are limited 2.
• Other antiviral agents like valacyclovir and famciclovir have also been shown to be effective in treating herpes simplex virus infections, including herpes labialis and genital herpes 3, 4.
• The treatment approach for herpetic whitlow may involve intermittent episodic therapy, intermittent suppressive therapy, or chronic suppressive therapy, depending on the clinical characteristics and patient preference 5.
• The choice of antiviral agent and dosing regimen should be based on evidence-based guidelines, taking into account the specific characteristics of the infection and the patient's needs 5.

Antiviral Agents for Herpetic Whitlow

• Acyclovir is an antiviral agent that has been used to treat herpetic whitlow, although its efficacy for this specific condition is not well established 2.
• Valacyclovir is a highly bioavailable prodrug of acyclovir that has been shown to be effective in treating herpes simplex virus infections, including herpes labialis and genital herpes 3, 4.
• Famciclovir is another antiviral agent that has been shown to be effective in treating herpes simplex virus infections, including herpes labialis and genital herpes 3, 4.

Clinical Considerations

• Herpetic whitlow is a painful and potentially debilitating condition that requires prompt and effective treatment 6.
• The treatment of herpetic whitlow should be guided by evidence-based guidelines, taking into account the specific characteristics of the infection and the patient's needs 5.
• The choice of antiviral agent and dosing regimen should be individualized based on the patient's clinical characteristics and preferences 5.
