Nutritional variant streptococci (NVS) are difficult to identify bacteria that can cause invasive infections such as endocarditis and
meningitis. NVS as a cause of peritonitis has not been routinely described. is case of NVS as the etiology of peritonitis associated
with previous neurosurgery and ventriculoperitoneal (VP) shunt revision demonstrates its potential role as a significant pathogen
in patients with peritonitis and VP shunts. erapy consists of vancomycin plus a second agent but since there are no standards
for susceptibility testing, clinical response remains the standard for determining the efficacy of treatment. When there is central
nervous system (CNS) involvement it is important to include drugs with appropriate CNS penetration.
1. Introduction
Nutritionally variant streptococci (NVS) comprise the
Abiotrophia sp. and Granulicatella sp. and are normal
residents of the oral cavity, gastrointestinal, and urogenital
tracts [1, 2]. Given that NVS are fastidious, grow slowly, and
can be pleiomorphic on Gram stain, these bacteria may be
misidentified [1]. NVS causes a variety of invasive infections,
most commonly endocarditis as a result of bacteremia [2].
Other reported infections include osteomyelitis, otitis media,
wound infections, septic arthritis, and pancreatic abscesses
and infections of the CNS [2–4]. Here we describe a case of
CNS shunt associated peritonitis where the cultures from
the CNS grew pure NVS. While peritonitis is a well-known
complication of VP shunt infections, this organism as a
pathogen in significant abdominal infections in children is
rarely reported.
2. Case Presentation
A 13-year-old girl with hydrocephalus managed with bilateral
ventriculoperitoneal (VP) shunts presented to the Emergency
Department (ED) with 24 hours of worsening generalized
abdominal pain, headaches, dizziness, and lethargy without
fever. She was born prematurely at 27 weeks of gestation
resulting in developmental delay and her adoptive parents
provided the history. Her parents reported she had decreased
oral intake for four days prior to presentation with chills but
no fever, emesis, or urinary symptoms. She had 20 VP shunt
revisions in her lifetime, the most recent being completed two
months prior to presentation. Her additional past medical
history was significant for epilepsy, chronic headaches, cere-
bral palsy, systemic lupus erythematosus, constipation, and
gastroesophageal reflux disease. Her medication list included
Fioricet, eletriptan, prednisone, hydrochloroquine, lansopra-
zole, ranitidine, phenobarbital, and polyethylene glycol.
In the ED she was ill-appearing, uncomfortable, and
actively complaining of abdominal pain. Her vital signs were
as follows: blood pressure 123/93, heart rate 126 beats/min,
temperature 37.6
∘
C, respiratory rate of 24/min, and pulse
oximetry of 100% on room air. Her physical exam showed that
her lung sounds were clear to auscultation and the heart rate
was sinus tachycardia with regular rhythm without murmur
on auscultation. Her abdomen was distended and diffusely
tender without guarding or rebound.
Initial laboratory values were as follows: white blood cell
count 10,000 cells/uL (normal 4.5–13 × 10
3
/uL) with 78.5%
