Helicobacter cinaedi and HIV

BACKGROUND Helicobacter cinaedi is a rare bacterium, accounting for only 0.2% of the positive isolates in blood cultures. Previous reports note that patients with H. cinaedi infection often have underlying diseases. H. cinaedi infection is diagnosed by blood culture. However, because of the slow growth of this bacterium in blood culture, the diagnosis can be missed. CASE REPORT A 78-year-old man gradually developed erythema and pain in his left arm, then left shoulder and both lower legs. The patient presented to our hospital on day 17...

We describe the case of an HIV-infected man who developed twice a Helicobacter cinaedi prosthetic joint infection. In our knowledge, it is the first case to date. Furthermore, it illustrates the fact that this bacterium is difficult to isolate and that recurrences can occur even after apparently successful treatment.

BACKGROUND: Helicobacter cinaedi causes bacteremia without characteristic clinical symptoms and is firstly isolated from human immunodeficiency virus (HIV)-positive homosexual men. FINDINGS: Here we describe, for the first time case report, two female patients with diabetes who had H. cinaedi bacteremia. Some cases of H. cinaedi bacteremia may require long-term administration of multiple antibiotics prior to the resolution of infection. CONCLUSIONS: Therefore, these cases indicate that it is important to consider H...

Helicobacter cinaedi, a gram-negative spiral bacillus that inhabits the intestinal tracts of rodents and primates, is associated with gastroenteritis in humans. H. cinaedi infection has been commonly reported in immunocompromised individuals such as human immunodeficiency virus-infected patients, but rarely in immunocompetent individuals. Prior contact with animals has attracted attention as a possible source of H. cinaedi infection. We report a case of meningitis in an immunocompetent 34-year-old woman who had daily contact with a kitten for a month...
