[Fulminant mycoplasma pneumoniae infection presenting with Stevens-Johnson syndrome & respiratory failure]

Abstract:
An 18-year-old man was admitted to Hamamatsu University Hospital on February 15, 1985, with high fever, vesicular and papular rash involving the skin and mouth, conjunctivitis, productive cough and dyspnea. A diagnosis of Stevens-Johnson syndrome was made by skin biopsy, and chest X-ray showed an infiltrate in the right lower lung filed. Despite treatment with corticosteroids and antibiotics, the mucocutaneous lesions did not heal, and the pneumonia progressed to both lung fields. Because the patient had developed dyspnea, a tracheotomy was performed, mechanical ventilatory support was instituted, and high-dose corticosteroid therapy was started. However, jaundice due to intrahepatic cholestasis, hematuria, hematochezia, sepsis, and subcutaneous and mediastinal emphysema ensued, and the patient died of respiratory failure on March 1. Postmortem examination of the lung demonstrated diffuse alveolar damage. The complement-fixation titer for Mycoplasma was 1:64, compared with a level of less than 1:4 on admission. This case was though to be one of fulminant Mycoplasma pneumoniae infection presenting with Stevens-Johnson syndrome, respiratory failure and other extra-pulmonary complications.
Insights
A rare case of severe Mycoplasma pneumoniae infection presented with Stevens-Johnson syndrome and respiratory failure. This fulminant infection led to multiple extra-pulmonary complications and ultimately, death despite intensive medical intervention.
Area of Science:
- Infectious Diseases
- Pulmonology
- Dermatology
Background:
- Stevens-Johnson syndrome is a severe mucocutaneous reaction, often triggered by infections or medications.
- Mycoplasma pneumoniae is a common cause of respiratory infections, but severe systemic complications are rare.
Observation:
- An 18-year-old male presented with symptoms consistent with SJS, including fever, rash, conjunctivitis, cough, and dyspnea.
- Despite initial treatment for SJS and pneumonia, the patient's condition rapidly deteriorated, with progression of lung infiltrates and development of jaundice, sepsis, and emphysema.
- Postmortem lung examination revealed diffuse alveolar damage.
Findings:
- Complement-fixation titers confirmed a significant rise in Mycoplasma pneumoniae antibodies.
- The clinical presentation and autopsy findings were attributed to a fulminant Mycoplasma pneumoniae infection complicated by SJS-like symptoms and multi-organ failure.
Implications:
- This case underscores the importance of considering Mycoplasma pneumoniae as a potential cause of severe mucocutaneous reactions and fulminant respiratory failure.
- Early recognition and specific treatment for Mycoplasma pneumoniae may be crucial in preventing severe outcomes.
- Further research into the immunopathogenesis of Mycoplasma pneumoniae-induced SJS is warranted.
