Conventional Criteria for Diagnosis of Sinusitis

2 1Based on Presence of at Least Major or M 2ajor and Minor Symptoms

IDSA Guideline for ABRS: CID.March 20, 2012

Severity of disease in adult and children

Definedi sease sever i t y:

Mild: -03VAS

Moderate: -47VAS

Severe: -810VAS

EPOS March 2012

Classification of ARS in adult/children Common cold/ acute viral rhinosinusits :

duration of symptoms for< 1 0 d

- Acutepostviralrhinosinusitis: increaseofsymptomsafter5d or per si st 10 12ent symptoms after d with < wk duration.

Natural history & time course of fever and RS sym ptom associated with uncomplicated viral URI in c

hildren

Acute rhinosinusitis can be divided into Common Coldand postviral rhinosinusitis. A small subgroup of post-

viral rhinosinusitis is caused by bacteria (ABRS).EPOS March 2012

Signs of ABSAt least 3 of:-Discoloured d/c-Severe local pain-Fever-Elevated ESR/CRP-Double sickening

Concomitant Chronic Disease

EPOS March 2012

Environmental Exposures Exposure to individual with respirator

y complaints was risk factor for RS in fection(adjusted OR = 3.7).

Increased levels of dampness in hom e has been associated with sinusitis.

Exposure to air pollution, irritants use d in preparation of pharmaceutical pr

oducts, during photocopying and fore st fire smoke.

EPOS March 2012

Anatomical factors

Anatomical variations including Halle r cells and septal deviation, nasal pol

yps, and choanal obstruction by beni gn adenoid tissue, or odontogenic so

urces of infections.

EPOS March 2012

Ciliary impairment

Ciliary function diminished during vir al and bacterial rhinosinusitis.

Exposure to cigarette smoke and alle rgic inflammation has been shown to

impair ciliary function.

Impaired mucociliary clearance in AR patients predisposes patients to ARSEPOS March

Smoking

- Active smokers with on going allergic inflammation have increased suscept

-ibility to ARS compared to non smoke - rs with on going allergic inflammatio

n, suggest i ng t hat exposur e t o ci ga rette smoke and allergic inflammatio

n is mediated via different and possib ly synergistic mechanisms.

Laryngopharyngeal reflux - - Pacheco Galvan et al. 1997 2006 hav

e shown significant associations betw o ooo ooo oooooooooo .

Recent systematic review, Flook andooo oo oooo oo oooo oooo ooooooooooo

between acid reflux, nasal symptoms , and ARS

EPOS March 2012

Anxiety and depression

Poor mental health, anxiety, or depre ssion is associated with susceptibility

to ARS

ooo oooooooo.

EPOS March 2012

Drug resistance

Amoxicillin is the most commonly use d antibiotic for mild ARS.

Increasing resistance to amoxicillin, p articularly in S. pneumoniae and

ooooooooooo. .

EPOS March 2012

Concomitant Chronic Disease Concomitant chronic disease (bronch

itis, asthma, CVS disease, DM, CA) in children has been associated with inc

reased risk of developing ARS second ary to influenza.

EPOS March 2012

Microbiologyofviral(commoncol d),postvi ral ,andbac terial ARS

Rhinoviruses (50%) and coronaviruses.

Influenza viruses, parainfluenza viruses, adenovirus, RSV, enterovirus.

S. pneumoniae, Haemophilus influenza, M. catarrhalis and S. aureus.

Streptococcal species , anaerobic bacteria

ABRS generally preceded by viral and - or post viral ARS.

Investigation

Bacteriology

Microbiological investigations are notoooooooo ooo ooooooooo oo ooo oo ooooo

ooooooooo .

May be required in research settings, or in atypical or recurrent disease

EPOS March 2012

Prevalence (Mean Percentage of Positive Sp ecimens) of Pathogens From Sinus Aspirate

s in ABS

XVI. Should Cultures Obtained by Sinus Punct ure or Endoscopy, Cultures of Nasopharyngea

l Swabs Sufficient?

Cultures be obtained by direct sinus aspi ration rather than by nasopharyngeal sw

ab (strong, moderate).

Endoscopically guided cultures of middle meatus may be considered as alternativ

e in adults, but their reliability in children has not been established (weak, mode

rate).

o ooooooooooooo oooooooo ooo oooooooooo and are not recommended for microbiolo

gic diagnosis of ABRS (strong, high)

- C Reactive Protein (CRP)

Raised in bacterial infection.

Limiting unnecessary antibiotic use.

ARS: low or normal CRP may identify l ow likelihood of positive bacterial infe

CRP levels are significantly correlate d with changes in CT scans.

EPOS March 2012

ESR levels correlated with CT change s in ARS

ESR >10 is predictive of sinus fluid le

vels or sinus opacity on CT scan.

Raised ESR is predictive of positive boooooooo ooooooo oo ooooo oooooooo oo oavage EPOS March

Procalcitonin

More severe bacterial infection

There is no evidence of its effectiven ess as a biomarker in ARS.

EPOS March 2012

Nasal Nitric Oxide (NO)

Sensitive indicator of presence of infl ammation and ciliary dysfunction.

Very low levels: primary ciliary dyskin esia, insignificant sinus obstruction.

Elevated levels: inflammation provid ed ostiomeatal patency maintained.

EPOS March 2012

Nasal endoscopy

Nasal endoscopy may be used to visu alize nasal and sinus anatomy and to

provide biopsy and microbiological sa.

EPOS March 2012

Imaging

CT scan

Modality of choice to confirm extent of pa thology and anatomy.

-Very severe disease, immuno compromis ed pt, suspicion of complications.

Routine CT scan in ARS little useful information

Plain sinus X Rays

Insensitive & limited usefulness

oooooooooo Insensitive & limited usefulness

EPOS March 2012

XVII. Which Imaging Is Most Useful for S evere ABRS who suspected to have Sup

purative complication? CT rather than MRI is recommended t

o localize infection and to guide furth er treatment (weak, low).

Differential Diagnosis of ARS

Viral Upper Respiratory Tract Infectioo

Allergic rhinitis

Orodontal disease

Rare diseases

Intracranial sepsis

Facial pain syndromes

Management of ARS

ARS resolves without antibiotic treat oo o ooo oooooo .

Symptomatic treatment and reassura nce is the preferred initial manageme

nt strategy for patients with mild sym.

Antibiotic therapy should be reserved for high fever or severe (unilateral) fa

ooooo.

For initial treatment, the most narrow- spectrum agent active against the li

kely pathogens (S. pneumoniae and H. influenzae) should be used.

(weak, moderate)

VII: Besides quinolone, Should Macrolide , bactrim, doxycycline, 2°/3° Gen Cep Us

- ed 2 ° line for ABR? Doxycycline may be used alternative in adults because it remains a

ctive against RS pathogens and has excellent PK/PD (weak, low).

2°/3° oral Gen Cep: no longer recommended for empiric monothera

py of ABRS due to resistance S. pneumoniae. Combination tx with

- 3° oral Gen plus clindamycin may be used as 2° line for children wi

th non–type I penicillin allergy or high endemic rates of PNS S. pneu

moniae (weak, moderate).

Not recommended

VIII. Which ATB Recommended f or ABRS in Adults/Children with

Penicillin Allergy? Adults:

Either doxycycline or quinolone(levofloxacin/moxifloxacin)

(strong, moderate)

Children:

Levofloxacin: type I hypersensitivity to penicillin

Clindamycin + 3° oral Gen Cep (cefixime/cefp odoxime): non–type I hypersensitivity to penic
