Literature Review

 

Cutaneous Warts 


Cutaneous warts are common skin lesions that are caused by human papillomavirus. Recurring or recalcitrant warts generally affect children and people who are immunocompromised.(1) “Although several potential treatment options exist for warts, there is no single treatment that ensures a complete response and lack of recurrence.”(1)

Treatments for warts include:

  • Cantharidin
  • Cryotherapy
  • Electrosurgery and curettage
  • Excision
  • Laser treatment
  • Chemical peels
  • Bleomycin
  • Immunotherapy(2)

Treatment of recurrent warts in children is often challenging as destructive options and surgery can be frightening and painful. “Contact immunotherapy offers a less painful approach than destructive measures.”(3)


“Squaric acid (SADBE) is an immunotherapy used to treat common warts.”(4) The treatment activates the immune system to combat the warts.(4)


A study enrolled 188 patients, ages two to 16, who had warts for an average of 17 months. Patients needed to satisfy two of the following criteria: single or multiple sites with several warts, warts resistant to repeated medical or surgical treatments, recurrent multiple warts, and patient or parent refusal to undergo destructive or surgical treatment.(5)


A total of 148 patients completed the therapy. “The treatment consisted of twice weekly applications of serial dilutions of SADBE, 0.03—3 percent for no more than 10 weeks.”(5) The study found complete resolution occurring in 83 percent of patients. There were no serious or unexpected side effects reported.(5)


The study concluded: “Our study substantiates the efficacy of SADBE in the treatment of recurrent/recalcitrant warts in children because of the ability to treat multiple lesions at the same, the high level of tolerability with absence of major side effects, the high clinical response rate with no recurrences or major side effects, and the high clinical response rate, with no recurrences in all of our patients who completed 24-month follow-up.”(5)

Herpes Labialis 

 

Herpes labialis is a common condition characterized by erosions on skin around the lips and nose.(1) Generally, the HSV-1 virus first infects the oral mucosa tissue. It then migrates to sensory organs and establishes latency. “The virus is later activated from latency by events including fever, stress, cold or flu infection, immunosuppression, and sunlight. Upon activation, the virus migrates down sensory neurons to epithelial cells, typically on the vermillion border of the lip, and causes cell lysis and outbreaks as epidermal lesions there.”(2)

Some medical conditions increase the risk of a person getting recurrent cold sores, also called oral herpes. These conditions include:

  • HIV
  • Undergoing chemotherapy
  • Organ recipient
  • Having conditions such as eczema or psoriasis(3)

A study conducted at a major medical center included adults between the ages of 18 to 69, who self-reported having six or more episodes of herpes labialis in the previous year. Half of the subjects received a sensitization dose of squaric acid on the arm at the initial visit; the other half received placebo. When the subjects developed a lesion they received a treatment dose of squaric acid, however 16 out of 28 patients did not experience another outbreak so did not receive another treatment dose. Of the subjects who did develop a lesion, “the median time to event for the placebo group was 40 days versus more than 122 days for the 2.0% SADBE group, which difference was highly significant.”(1)
