Postherpetic Cutaneous Streptococcal Infection
Introduction
Postherpetic cutaneous streptococcal infection (PCSI) is a rare but serious complication of herpes zoster (shingles). It is caused by a secondary infection of the skin with bacteria, most commonly Streptococcus pyogenes (group A streptococcus). PCSI can occur in up to 10% of patients with herpes zoster and is more common in immunocompromised individuals.
Symptoms
The symptoms of PCSI include:
Painful, erythematous skin lesions
Bullae (fluid-filled blisters)
Pustules (pus-filled blisters)
Fever
Chills
Malaise
Diagnosis
The diagnosis of PCSI is based on the clinical presentation and a Gram stain of the skin lesions. A Gram stain is a laboratory test that can identify the bacteria responsible for the infection.
Treatment
The treatment of PCSI includes:
Antibiotics to treat the bacterial infection
Antiviral medications to treat the herpes zoster virus
Pain relievers
Wound care
Complications
PCSI can lead to a number of complications, including:
Sepsis
Necrotizing fasciitis
Toxic shock syndrome
Death
Prevention
There is no specific prevention for PCSI. However, people who are at risk for PCSI should take steps to avoid exposure to bacteria, such as:
Washing their hands frequently
Avoiding contact with people who are sick
Covering open wounds
Prognosis
The prognosis for PCSI depends on the severity of the infection and the underlying health of the patient. With prompt treatment, most patients make a full recovery. However, in some cases, PCSI can be fatal.
Discussion
PCSI is a serious complication of herpes zoster that can lead to a number of complications. It is important to be aware of the signs and symptoms of PCSI and to seek medical attention promptly if you think you may have this infection.
