Title: APPROACH TO PERIODIC FEVER SYNDROMES


1
APPROACH TO PERIODIC FEVER SYNDROMES
  • Sarah S. Long, M.D.
  • Professor of Pediatrics
  • Drexel University College of Medicine
  • Chief, Section of Infectious Diseases
  • St. Christophers Hospital for Children
  • Dr. Long has no conflict to disclose

Case
  • A 15-year-old girl is referred because of a
  • persistent febrile illness. Twelve weeks ago
  • she had the acute onset of fever to 1030,
  • headache, myalgia, sore throat and nasal
  • congestion. A throat culture was negative
  • for group A streptococcus. Over the next
  • week high fever and congestion abated but
  • parents report that she has had persisting low
  • grade fever (to 99.8 every 2-3 days),
  • complains of headache, sore throat,
  • weakness, fatigue, and has poor color, poor
  • appetite. She complains of sudden shooting
  • pains in arms and legs.

3
Case continued
  • On attempt to return to school 4 weeks
  • ago she was there only 2 hours when the
  • school nurse reported that the patient
  • felt faint, chilly and sweaty, and was
  • unable to stay in class. She has not
  • returned to school and is now home
  • tutored.
  • What is your next diagnostic step?

DEMO PSYCHO SYMPTOMS BY ILLNESS
  • Fatigued Depressed JIA
  • White race
  • Femalegtgtmale
  • Low socioeco
  • High parent ed
  • Acute onset
  • Overachiever

12
PSYCHOLOGICAL SYMPTOMS BY ILLNESS
  • Fatigued Depressed JIA
  • Social/extra act
  • Sad all the time
  • Lonely
  • Hate/want to hurt self
  • Not as good as others
  • Dont get along/not liked
  • Feel overtired
  • Not much energy
  • Somatic complaints
  • See doctors alot
  • Need help
  • Internalize stress

TIMELINE EVIDENCE BASE FATIGUE
1990s
NIH definition CFS
Case series pediatrics
Immunologic studies
EBV, other ID
2000s
Lyme, other ID
Follow-up case series
Non Dx pediatrics
Endocrine hypoadrenia
Cardio neurally med. hypotension
postural tachy syndrome
Joint hypermobility ?Ehlers Danlos

EVIDENCE BASE FATIGUE
Orthostatic instability in a population-based stud
y of chronic fatigue syndrome. Jones JF et al.
Am J Med, December 2005 58 adults CFS 55
controls Inpatient 2-day evaluation
Head-up tilt test pos. 30 CFS vs 48

TYPICAL FINDINGS IN PATIENTS WITH
DECONDITIONING
  • Age gt 12 years
  • Preillness achievement high
  • Family expectations high
  • Acute febrile illness with onset easily dated
  • Family and outside attention high
  • Lengthy list, but vague complaints
  • Odd complaints (eg, shooting pains 30-
  • second blindness stereotypic sporadic,
  • brief unilateral tremors, jerks, or
    paralysis)
  • No daytime sleep
  • Preserved weight
  • Extreme cooperation with examination
  • Normal physical and neurologic examination
  • Normal results of screening laboratory tests

16
MANAGEMENT DECONDITIONING
Patient Validate symptoms as accurate
Incremental, forced return to school
Exercise Predict symptoms No
school absence w/o ped. visit No
expectation performance
Family Validate their concern Validate
their medical pursuit Justify your
diagnosis Change focus to health
Avoid How do you feel? No expectation
performance

APPROACHING RECURRING FEVER ILLNESSES
History History History
Prolonged or relapsed single illness Multiple
simple illnesses Recurrences at irregular
intervals
Recurrences regular/predictable/clockwork Duration
Response to antipyretics, NSAIDs,
antibiotics Occurrence with immunizations
Additional Features of Episodes
Symptoms URI, AOM
Target organ? Rash? Mouth ulcers?

MORE HISTORY
Interval between episodes
Lingering symptoms Multiple URIs, asthma Severe
bacterial/viral infections
Perfectly well, energetic Few regular
illnesses Good growth development
Family History
Genetic background Sibs not ill with
