The Child With Recurrent Fever
The Child with Recurrent Fever: The Alphabet soup of Periodic Fever Syndromes Suzanne C Li, MD PhD Joseph M Sanzari Children’s Hospital Division of Pediatric Rheumatology 1 Overview • Fever • Recurrent fever • Periodic Fever Syndromes • Features of Periodic Fever Syndromes • Evaluation of a child with recurrent fever • Innate immunity • Autoinflammatory Diseases 2 Fever • Very common symptom in children • Usually short-lived, benign • Prolonged fever without obvious cause fever of unknown origin (FUO) • duration: minimum 14-21 days • Recurrent fever: Different patterns • Single illness with waxing and waning course • Repeated unrelated illnesses of same organ system • Multiple illnesses of different organ systems • Periodic fevers: recurring episodes with similar sx 3 Marshall G, J Infection 2014;68(suppl):S83 Long, S. Ped Clin N AM 2005;52:811 Recurrent Fever: could represent • Recurrent infections •Viral: common for 2-3 yo to have 6-10 URI/yr •daycare, school aged sibs •Bacterial: may be 2o to •structural anomaly, cystic fibrosis, immunodeficiency •Parasite: travel history • Malignancy: lymphoma, leukemia • Systemic inflammatory d: rheum, IBD •Systemic Juvenile Arthritis, Lupus, Behcet’s, Vasculitis •Periodic Fever Syndromes 4 Marshall G, J Infection 2014;68(suppl):S83 Long, S. Ped Clin N AM 2005;52:811 Periodic Fever Syndromes (PFS) • Recurrent, self-limited febrile episodes • Fever is a major feature • Other sx are similar, predictable • Episodes last days to few weeks • Clockwork or irregular periodicity • Well in between episodes • Normal labs in between episodes •Different than systemic inflammatory d, malignancy • Normal growth and development 5 Periodic Fever Syndromes • Cyclic neutropenia: fever 2o to infection • Classical PFS: Not associated with infection •Hereditary •FMF = Familial Mediterranean Fever •HIDS = Hyper-immunoglobulin D Syndrome •TRAPS = Tumor-Necrosis-Factor ReceptorAssociated Periodic Syndrome •FCAS = Familial Cold Autoinflammatory Syndrome •Non-hereditary PFS •PFAPA = Periodic fever, aphthous stomatitis, pharyngitis, adenitis 6 Periodicity of PFS • Very Regular, Predictable • Cyclic neutropenia • PFAPA • Variable regularity •Familial Mediterranean Fever •Hyper-immunoglobulin D Syndrome • Least regular •Tumor-Necrosis-Factor Receptor-Associated Periodic Syndrome •Familial Cold Autoinflammatory Syndrome Drenth and van der Meer, 2001 7 Cyclic Neutropenia • Presents within first few months of life • Most regular fever episodes: every 21 days • Neutropenia (<200 cells/mm3) lasts 3-5 days • Develop infection during nadir • Dx: serial CBCs: WBC often normal at time of fever 8 Dale and Hammond, 1988 Cyclic Neutropenia •Common sx and problems: •Apthous stomatitis, pharyngitis, gingivitis, periodontitis, OM, sinusitis, lymphadenopathy • cellulitis, furunculosis • Fatigue, headache, myalgia, abdominal and bone pain •Defect: ELA2: neutrophil elastase gene •About 1/3 familial: Autosomal Dominant •ELA2 defects also severe congenital neutropenia • Rx: G-CSF 9 Classical Periodic Fever Syndromes: Clinical and Laboratory pattern • Acute onset of fever: T103-105oF • may have prodrome few hours to 1 day before • High inflammation during febrile episode • ESR, CRP ; CRP can be >100 • WBC in some • If prolonged episode (i.e.,TRAPS), anemia, thrombocytosis may be present • End of episode: rapid improvement in sx • Complete normalization of labs for most 10 Hausmann & Dedeoglu, Dermatol Clincs 2013;31:484 Hofer et al Rheumatol 2014 PFAPA (Periodic fever, aphthous stomatitis, pharyngitis, adenitis) • Most common Periodic Fever Syndrome • Median age of onset: 1.7-2.7 yr (range 0.1-12 yr) • Episodes: •Duration 4 d (range 1-10 d) •Interval between episodes 4 wk (range 1-12) • Features: • Aphthous Stomatitis: 21-70% • Pharyngitis: 61-90% • Cervical Adenopathy: 46-88% drpaulose.com 11 Hausmann & Dedeoglu, Dermatol Clincs 2013;31:484 Hofer et al Rheumatol 2014 PFAPA Diagnotic Criteria 1.Regularly recurring fevers beginning by age 5yr* 2.Constitutional sx in absence of URI with at least 1 of following: apthous stomatitis, cervical lymphadenitis, pharyngitis 3.Rule out cyclic neutropenia 4.Asymptomatic in between episodes 5.Normal growth and development *adolescent and adult onset has been reported Feder et al J Pediatr 1999;135:15 12 PFAPA Symptoms and Course • Prodrome: fatigue, HA, irritability, abdominal pain • Other sx: nausea, diarrhea, lethargy, myalgia •Arthralgia but NOT arthritis •No genetic basis identified, all ethnicities • 12% Family Hx of PFAPA • M > F 1.2-2.3 to 1 •Prognosis excellent •Mean disease duration 6.3 yr (range 5.4-7.3) •15% have persistent d but severity •No long-term sequelae 13 PFAPA Treatment • Treatment related to discomfort of child, family • No identified long-term problems • Disease self-limited in most patients • Supportive: anti-pyretics • Abort episodes: •Corticosteroid: 84-90+% respond to 1-2 doses •But may episode intervals •Anti-IL-1, anti-TNF reported to be effective • Prevent episodes: • Cimetidine: 27-40% • Tonsillectomy: 64-100% Hausmann & Dedeoglu, Dermatol Clincs 2013;31:484 Wurster et al J Pediatr 2011;159:958 14 Familial Mediterranean Fever (FMF) • Most common inherited PFS: Aut Recessive • Sephardic Jews, Armenians, Arabs, and Turks • Genetic defect: MEVK gene = pyrin Hypothesized founder migration Zadeh et al Genetics Med 2011;13:263 Hashkes and Toker, Ped Clin N Am 2012;59:447 15 Hausmann & Dedeoglu, Dermatol Clincs 2013;31:484 Familial Mediterranean Fever (FMF) • 80% present by age 10 yr • Mean onset age 9.6 yr; 30% < 2 yo • Episodes: • Duration: 12-72 hr • Intervals: monthly to irregular intervals (1/wk to 1/yr) • Most common Features: •Serositis: peritonitis > pleuritis > pericarditis • Arthritis: usually knee or ankle • Rash: Erysipelas on extremities • Pattern can change; varies with residence •may initially only have fever Hashkes et al, Ped Clin N Am 2012;59:447 16 Hausmann et al, Derm Clincs 2013;31:484 Drenth and van der Meer, NEJM 2001 FMF Symptoms • Abdominal pain: 95% • can mimic acute appendicitis • diarrhea, nausea, vomiting, and constipation • Arthritis: 37-77% Y.

Marshall 2014 J. Infection 29 Diagnosis of Hereditary PFS • Diagnosis should be based upon clinical features, history, laboratory studies •Genetic analysis expensive, should not use as screening tool • Discrepancies between identified and expected genetic analysis •FMF: ~30% have only 1 mutant MEFV allele •~60% of pt with autoinflammatory phenotype pattern do not have mutation in any of known gene loci Kastner et al Cell 2010;140:784 30 Hereditary PFS have led to major advances in understanding immunity • Two types of immunity: •Acquired: T and B lymphocytes •Unique receptors generated through recombination, somatic mutation after antigen activation •Innate: non-modifiable immune protection •PFS have defects in innate immune system •CAPS, FMF, HIDS: inflammasome or its function •TRAPS: mutant receptor affects effector cell survival • PFS defects inflammation 31 Innate Immunity Universal Pathogen protection mechanism • Found in plants, invertebrates, vertebrates • Effector cells recognize microbial molecules, cellular waste • Macrophage, Dendritic cell, Monocytes, Neutrophils • Recognize pathogens thru Pathogen Recognition Receptors (PRRs) • Binding to PRR Inflammatory response • Secretion of cytokines and chemokines • Recruitment of immune cells 32 Pathogen recognition leads to inflammation Recognition of pathogens by effector cell receptors (TLRs and other PRRs) Binding to PRR triggers • cytokine synthesis •Inflammasome activation • cleavage of pro-IL-1 active IL-1 CAPS, FMF, HIDS: defects related to inflammasome IL-1 causes: • Fever • Recruitment of leukocytes • Activation of lymphocytes 33 Hashkes and Toker, Ped Clin N Am 2012;59:447; Hofmann 2011; Zen 2013 Hereditary PFS = Monogenic Autoinflammatory Diseases • New name based upon pathology •Autoinflammatory diseases •In contrast to Autoimmune diseases •Autoantibodies and reactive T cells not found in autoinflammatory diseases • Il-1 plays key role in Autoinflammatory diseases • Autoinflammatory processes now recognized as involved in many other diseases 34 Diseases with an Autoinflammatory Component • Systemic Juvenile Idiopathic Arthritis, Spondyloarthritis • Crohn’s disease • Gout • Type II Diabetes • Atherosclerosis • Contact Dermatitis • Vitiligo 35 Thank You 36
