Insights
Helicobacter cinaedi (H. cinaedi) bacteremia is common in healthy individuals. Cellulitis is a frequent symptom, but some patients only show fever, especially with hospital-acquired infections.
Area of Science:
- Infectious Diseases
- Microbiology
- Clinical Medicine
Background:
- Increasing reports on Helicobacter cinaedi (H. cinaedi) bacteremia clinical and pathological features.
- Limited data exists on H. cinaedi bacteremia in healthy individuals.
Purpose of the Study:
- To assess the clinical features of community-acquired H. cinaedi bacteremia.
- To investigate H. cinaedi infections in immunocompetent individuals.
Main Methods:
- Retrospective observational study.
- Data collected from a Japanese tertiary care hospital (January 2009 - March 2014).
- Identified patients with H. cinaedi isolation.
Main Results:
- 28 patients included; 12 with community-acquired H. cinaedi bacteremia.
- Cellulitis was the most common clinical feature (n=17).
- Nearly half of healthcare-associated/nosocomial bacteremia patients had only fever.
- Successful treatment with 14-day cephalosporins or tetracycline.
Conclusions:
- H. cinaedi infections are prevalent in immunocompetent, community-dwelling individuals.
- Highlights the importance of recognizing H. cinaedi in non-hospitalized populations.
Background:
There are growing numbers of reports concerning the clinical and pathological features of Helicobacter cinaedi (H. cinaedi) bacteremia; however, few reports have discussed the features of this condition in healthy individuals.
Patients And Methods:
A retrospective observational study was conducted at a Japanese tertiary care hospital to assess the clinical features of community-acquired H. cinaedi. All patients in whom H. cinaedi was isolated between January 2009 and March 2014 were identified from the hospital database.
Results:
Of the 28 patients included in the study, 12 had community-acquired H. cinaedi bacteremia. The most common clinical feature was cellulitis (n = 17). However, nearly half of the patients with healthcare-associated or nosocomial-associated bacteremia displayed no symptoms with the exception of fever. Most patients were successfully treated with a 14-day regime of third-generation cephalosporins or tetracycline.
Conclusions:
Our results show that H. cinaedi infections are quite common in immunocompetent community-dwelling individuals.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
