Chief Complaint

  • Fever off and on for 8 days

Present illness
Present Illness

  • A 6 year-old boy suffered from fever off and on for 8 days. He also complained of cough, rhinorrhea and difficult to expectorate sputum. He was taken to LMD twice and our OPD on 91/04/30, but the symptoms persisted in spite of drugs use. So he was taken to our OPD again on 91/05/03. Physical examination revealed decreased breathing sound on right chest. CXR showed lobar pneumonia.

Final diagnosis
Final Diagnosis

  • Mycoplasmal lobar pneumonia, complicated with prolonged fever, skin rashes, right lung pleural effusion, and hemolytic anemia

Mycoplasma pneumoniae
Mycoplasma Pneumoniae

  • In 1944, M. pneumoniae was reported by Monroe Eaton, originally called the Eaton agent.

  • Smallest free-living microorganism, belongs to the class Mollicutes.

  • Mycoplasmas lack a cell wall, so tend to be pleomorphic.

Clinical manifestations
Clinical Manifestations

  • M. pneumoniae causes approximately 20% of all cases of pneumonia.

  • Peak incidence at 6-21 years of age.

  • Incubation period of 2-3 weeks.

  • Transmission by inhalation of infected droplet aerosols.

Case report

  • Pneumonia is the most important clinical manifestation of M. pneumoniae infection.

    * Bronchopneumonia pattern mostly.

    Lobar pneumonia and large amount

    pleural fluid are unusual.

    Pediat Radiol 1989;19(8):499-503

    * Respiratory disease other than

    pneumonia: unspecific URI, pharyngitis,

    AOM, croup, sinusitis, bronchitis,

    bronchiolitis, asthma.

Case report

  • Cutaneous manifestations : common. pneumoniae infection.

    * Exanthem and enanthem of Mycoplasma

    pneumoniae infection are observed in 5 to

    24% of cases

    AAP, Report of Committee on Infectious Diseases, 1994:333-5

    * Most common with an erythematous

    maculopapular rash on the trunk and back;

    discrete (rubelliform) or confluent


    * Most serious presentation: Erythema

    multiforme and Stevens-Johnson syndrome.

    Clini Pediatrics 1991:30(1),42-9

Case report

  • Hematologic manifestations: pneumoniae infection.

    * Hemolytic anemia: usually mild,

    however, it may become severe and

    result in 50% reduction in hemoglobin


    Pediat Infec Dis J 1998;17(2):173-7

    * Direct Coombs test usually positive.

    * Steroid administration may be


    South Med J 1990;83(9):1106-8

Case report

Hemolytic anemia is presumably related to the presence of cold agglutinins in serum which at high concentration, may agglutinate erythrocytes at 37℃

Rev Pneumol Clin 1990,46(2),83-4

Case report

  • Gastrointestinal findings are nonspecific with nausea, vomiting, abdominal pain, and/or diarrhea.

  • Neurologic disease association was reported 2.6-4.8%.

    * Encephalitis, meningitis, transverse

    myelitis, psychosis, Bell palsy and

    Guillain-Barre` syndrome.

  • Arthritis in association with M.pneumoniae

    infection have not been established.

Radiographic manifestation i
Radiographic Manifestation (I) with pleuropneumonia than in simple pneumonia cases.

Interstitial infiltration was more commonly seen in pediatric than adult patients (46% vs 20%)

Unilateral lesions 80%

Single lobe lesions 77%

Lower lobe predominant 69%

Pleural effusion 7%

Radiographic manifestation ii
Radiographic Manifestation (II) with pleuropneumonia than in simple pneumonia cases.

  • Unilateral infiltration 84%

  • Lower lobe predominance 60%

  • Confluent consolidation 56%

  • Patchy consolidation 33%

  • Pleural effusion 24%

    長庚醫學雜誌 1991;14(3):156-62

Diagnosis i
Diagnosis (I) with pleuropneumonia than in simple pneumonia cases.

  • WBC, CRP, ESR are non-specific, may be normal or elevated.

  • Growth of the organism takes weeks, generally only in expertise laboratories.

  • PCR is sensitive and specific.

  • Serologic testing : Cold agglutinins, titer of >1:64 is suggestive of infection; Anti-mycoplasmal Ab detection, fourfold or greater rise are considered diagnostic.

Diagnosis ii
Diagnosis (II) with pleuropneumonia than in simple pneumonia cases.

  • Imaging : Interstitial infiltrate or bronchopneumonia pattern. Lobar consolidation and pleural effusion are uncommon but may occur.

Treatment with pleuropneumonia than in simple pneumonia cases.

  • Erythromycin is the drug of choice.

    (40-50mg/kg/24hr q6h for 10-14 days).

  • Newer macrolides:

    Azithromycin (10mg/kg on day 1, and

    5mg/kg/24hr on days 2-5) or

    Clarithromycin (15mg/kg/24hr given in two

    divided doses for 10 days).

Empiric therapy for lobar pneumonia
Empiric Therapy for Lobar Pneumonia with pleuropneumonia than in simple pneumonia cases.

  • Clinically moderate to severely toxic, treat empirically for S. pneumonia, S. pyogens ( and H. influenzae type b in unimmunized children)

  • In toxic children, tests for Mycoplasma should be considered because focal pneumonia is a rare presentation

Case report

  • Cefuroxime intravenously, ceftriaxone or cefotaxime intravenously

  • For anti-staphylococcal coverage, add to the above, either: nafcillin, oxacillin, or clindamycin

  • For Mycoplasma: intravenous erythromycin or azithromycin; or oral erythromycin, azithromycin, or clarithromycin.

Pneumonia with pleural fluid or empyema
Pneumonia, with pleural fluid or empyema intravenously

  • Treat empirically for S. pneumonia, S. pyogenes, and S. aureus ( and H. influenzae type b in unimmunized children)

  • Consider aspiration pneumonia with anaerobic oral flora as pathogens; needle or catheter aspiration of pleural fluid, with drainage, is often required for clinical cure.

Case report

  • Ceftriaxone or cefotaxime intravenously

  • For antistaphylococcal covarage, add to the above either: nafcillin, oxacillin, or clindamycin (also covers anaerobes found in aspiration pneumonia as well as most pneumoncocci)

  • Single agent therapy with meropenem, or ticarcillin/clavulanate (Timentin) both of which cover both aerobic and anaerobic pathogens
