TOPLINE:
, according to the findings from a retrospective study.
METHODOLOGY:
- Researchers reviewed the electronic medical records of infants aged ≤ 60 days who received a pediatric dermatology consultation at six US academic institutions between September 2013 and August 2019.
- Among 879 consults, 183 afebrile infants were identified as having presented with pustules, vesicles, and/or bullae.
- Infectious disease workups included blood cultures, urine cultures, lumbar punctures, and HSV testing using viral skin culture, direct immunofluorescence assay, and/or polymerase chain reaction.
- Patients were categorized by gestational age as preterm (< 37 weeks), full-term (37-42 weeks), and post-term (≥ 42 weeks).
- Overall, 67.8% of infants had pustules, 31.1% had vesicles, and 10.4% had bullae.
TAKEAWAY:
- None of the cases showed positive cerebrospinal fluid or pathogenic blood cultures. In 122 of the cases (66.6%), a noninfectious cause was diagnosed, and an infectious cause was diagnosed in 71 cases (38.8%; some patients had more than one diagnosis).
- Of the 127 newborns evaluated for HSV infection, nine (7.1%) tested positive, of whom seven (5.5%) had disease affecting the skin, eye, and mouth and were full- term infants, and two (1.6%) had disseminated HSV and were preterm infants.
- Angioinvasive fungal infection was diagnosed in five infants (2.7%), all of whom were preterm infants (< 28 weeks gestational age).
- The risk for life-threatening disease was higher in preterm infants born before 32 weeks of gestational age (P < .01) compared with those born after 32 weeks.
IN PRACTICE:
“Full-term, well-appearing, afebrile infants ≤ 60 days of age presenting with pustules or vesicles may not require full SBI [serious bacterial infection] work-up, although larger studies are needed,” the authors concluded. Testing for HSV, they added, “is recommended in all infants with vesicles, grouped pustules, or pustules accompanied by punched out or grouped erosions,” and preterm infants “should be assessed for disseminated fungal infection and HSV in the setting of fluid-filled skin lesions.”
SOURCE:
The study was led by Sonora Yun, BA, Columbia University, New York City, and was published online in Pediatrics.
LIMITATIONS:
The data were limited by the sample size and very low incidence of serious infections. Infants probably had atypical or severe presentations that warranted pediatric dermatology consultation, which may have led to overrepresentation of infectious disease rates. The study inclusion was restricted to those who received a dermatology consult; therefore, the findings may not be generalizable to outpatient primary care.
DISCLOSURES:
This study did not receive any external funding. The authors declared that they had no relevant conflicts of interest.
