Mucosal Respiratory Syndrome: A Systematic Literature Review.

BACKGROUND: Mycoplasma pneumoniae atypical pneumonia is frequently associated with erythema multiforme. Occasionally, a mycoplasma infection does not trigger any cutaneous but exclusively mucosal lesions. The term mucosal respiratory syndrome is employed to denote the latter condition. Available reviews do not address the possible association of mucosal respiratory syndrome with further atypical bacterial pathogens such as Chlamydophila pneumoniae, Chlamydophila psittaci, Coxiella burnetii, Francisella tularensis, or Legionella species. We therefore performed a systematic review of the literature addressing this issue in the National Library of Medicine, Excerpta Medica, and Web of Science databases. SUMMARY: We found 63 patients (≤18 years, n = 36; >18 years, n = 27; 54 males and 9 females) affected by a mucosal respiratory syndrome. Fifty-three cases were temporally associated with a M. pneumoniae and 5 with a C. pneumoniae infection. No cases temporally associated with C. psittaci, C. burnetii, F. tularensis, or Legionella species infection were found. Two cases were temporally associated with Epstein-Barr virus or influenzavirus B, respectively.

Skin and Mucous Membrane Eruptions Associated with Chlamydophila Pneumoniae Respiratory Infections: Literature Review.

BACKGROUND: Mycoplasma pneumoniae pneumonia is sometimes associated with skin or mucous membrane eruptions. Available reviews do not address the association of Chlamydophila pneumoniae pneumonia with skin eruptions. We therefore conducted a systematic review of the literature addressing this issue. The National Library of Medicine, Excerpta Medica, and Web of Science databases were employed. SUMMARY: In two reports, skin lesions and especially urticaria were more common (p < 0.05) in atypical pneumonia caused by C. pneumoniae as compared with M. pneumoniae. We found 47 patients (<18 years, n = 16; ≥18 years, n = 31) affected by a C. pneumoniae atypical pneumonia, which was associated with erythema nodosum, erythema multiforme minus, erythema multiforme majus, isolated mucositis, or cutaneous vasculitis. We also found the case of a boy with C. pneumoniae pneumonia and acute generalized exanthematous pustulosis. We did not find any case of C. pneumoniae respiratory infection associated with either Gianotti-Crosti syndrome, pityriasis lichenoides et varioliformis acuta Mucha-Habermann, or varicella-like skin eruptions.

Tuberculosis-related choriocapillaritis (multifocal-serpiginous choroiditis): follow-up and precise monitoring of therapy by indocyanine green angiography.

To report the case of a patient initially diagnosed with acute posterior multifocal placoid pigment epitheliopathy (APMPPE), characterized by relentless evolution despite high-dose steroid therapy. An interferon-gamma release assay (IGRA) indicated a diagnosis of suspected tuberculous choriocapillaritis and the disease responded only to massive inflammation suppressive therapy and antibiotic therapy. Case report. Review of clinical features and investigational procedures. Smoldering relentless evolution and subsequent arrest of progression could be precisely monitored by indocyanine green angiography (ICGA). The patient did not recover after standard anti-tubercolosis (TB) therapy combined with corticosteroid. A fourth antibiotic had to be added in order to stop the progression of the retinal disease. In each case of choriocapillaritis such as APMPPE an infectious cause including TB has to be excluded making IGRA tests unavoidable. As the main structure involved is the choriocapillaris the most precise follow-up or monitoring is obtained with ICGA.
