Infection because of herpes simplex virus (HSV) that is resistant to acyclovir (ACV) poses treatment challenges in hematopoietic cell transplant (HCT) patients. We present a series of patients with ACV-resistant HSV following HCT who were successfully treated with continuous infusion high-dose ACV after failing standard treatment regimens for ACV-resistant HSV. does doxycycline work for acne Related: Opportunistic infections and complications. Infection with herpes viruses can cause sores and, in some cases, ulcers in the mouths and genitals of people. These sores can usually be treated with antiviral drugs such as acyclovir (Zovirax), Valtrex (valacyclovir) or Famvir (famciclovir). Unfortunately, cases of herpes that are resistant to these drugs are increasingly leaving doctors and their patients with few options. However, a group of doctors in New York recently reported the case of a person with AIDS who successfully recovered from drug-resistant herpes when he was treated with the immune booster imiquimod (Aldara). The doctors provided details on a 34-year-old man whose CD4 count was 200 cells and whose viral load was “undetectable.” He had been taking highly active antiretroviral therapy (HAART) for about a year and had symptoms of herpes on his genitals for about five months. Doctors prescribed the following regimens one at a time to treat the herpes infection: acyclovir – 1, 200 mg/day for one month Valtrex – 2 grams/day for one month Famvir – 1, 500 mg/day for one month Because these drugs did not help, doctors then prescribed 5% imiquimod cream, which the man applied to his lesions and then washed off eight hours later. He did this three times in one week and then stopped the drug.

Drug resistance to acyclovir and related drugs eg, famciclovir or valacyclovir is rare in immunocompetent hosts but is seen more commonly. A 46-year-old Hispanic homosexual man was seen because of persistent painful hyperkeratotic lesions of the right leg and left hip each greater than 2 cm in diameter (Figure 1). Results of laboratory investigations disclosed a CD4 cell count of 0.2× 10/L. History disclosed Kaposi's sarcoma, bacillary angiomatosis, cryptococcal meningitis, Pneumocystis pneumonia, and disseminated Mycobacterium avium complex. Medications included dideoxyinosine, sulfamethoxazole and trimethoprim, fluconazole, clarithromycin, ethambutol, morphine, and diphenoxylate. Cultures taken from the lesions yielded varicella zoster virus (VZV). He had been treated with oral acyclovir (800 mg five times daily) with initial flattening of the lesions but without complete resolution. A subsequent viral culture of the lesions yielded VZV that was acyclovir resistant owing to a thymidine kinase deficiency. By Mary Engel / Fred Hutch News Service An experimental drug for genital herpes that showed promising results in a small, early-phase clinical trial has done so again in a second trial, this time outperforming the current treatment in a head-to-head comparison, according to a study published Tuesday in JAMA. “We showed that the new drug, pritelivir, which is still in early development, reduced the rate of viral shedding more than the standard, valacyclovir,” said Dr. Anna Wald, a University of Washington and Fred Hutchinson Cancer Research Center researcher and lead author of the new study. In fact, Wald added, “I was surprised at how much more effective pritelivir was.” Viral shedding is the stage at which the virus is active and can potentially be spread to sexual partners. Fear of infecting a partner is “the biggest concern for most people with herpes,” said Wald, who is the medical director at the UW Virology Research Clinic. The results of the phase 2, randomized, double-blind trial published today showed that when people with genital herpes took a daily oral dose of pritelivir, they reduced their rate of viral shedding by half compared to when they took valacyclovir. Genital herpes is caused by the herpes simplex virus, usually the type called HSV-2. Lifelong and incurable, it is one of the most frequent sexually transmitted infections worldwide. The next step, Wald said, is to continue testing pritelivir to assess its safety.
