Symptomless myocarditis and myalgia in viral and Mycoplasma pneumoniae infections.

Symptomless myocarditis and myalgia in viral and Mycoplasma pneumoniae infections

Of i8 patients admitted to hospital with proved viral (influenza A, echo-9 and -30) or Mycoplasma pneumoniae infections, 6young adults between I5 and27years showed electrocardiographic evidence ofsymptomless myocarditis, which was invariably associated with myalgia. Myalgia is an important symptom presaging myocarditis and is an indication for an early electrocardiogram in all patients with sus...

Letter: Symptomless myocarditis and myalgia in viral and Mycoplasma pneumoniae infections.

Sir: We are surprised at Drs. Lewes, Rainford, and Lane (British Heart Journal, I974, 36, 924) seizing upon such a nonspecific symptom as myalgia as being a clue to any complication, much less being indicative of myocarditis. In our experience, myalgia accompanies viral influenza as regularly as a runny nose accompanies the common cold. Evanescent and minor ST-T wave changes are, also, nonspeci...

Cytokines in Mycoplasma pneumoniae infections.

Mycoplasma pneumoniae (M. pneumoniae) is one of the smallest free-living bacteria known. Along with other unique characteristics of this genus, it lacks the typical peptidoglycan cell wall of most eubacteria. Best known for causing tracheobronchitis and atypical pneumonia in humans, this pathogen also causes a number of extrapulmonary syndromes such as meningitis/encephalitis and arthritis. Rec...

Immune responses in Mycoplasma pneumoniae infections.

All children with Mycoplasma pneumoniae infection showed a significant response in IgG immunofluorescent (IMF) antibody titers, which were similar to that of complement-fixing (CF) antibody titers. However, there was a certain degree of variation in IgM IMF antibody response and its persistence. This variation also occurred in cases with pre-existing specific antibodies and good CF and IgG IMF ...
