Review Meta AnalysisMacrolides for treatment of Haemophilus ducreyi infection in sexually active adults.
Chancroid is a genital ulcerative disease caused by Haemophilus ducreyi. This microorganism is endemic in Africa, where it can cause up to 10% of genital ulcers. Macrolides may be an effective alternative to treat chancroid and, based on their oral administration and duration of therapy, could be considered as first line therapy. ⋯ At present, the quality of the evidence on the effectiveness and safety of macrolides for treatment of H ducreyi infection in sexually active adults is low, implying that we are uncertain about the estimated treatment effect. There is no statistically significant difference between the available therapeutic alternatives for the treatment of sexually active adults with genital ulcers compatible with chancroid. Low quality evidence suggests that azithromycin could be considered as the first therapeutic alternative, based on their mono-dose oral administration, with a similar safety and effectiveness profile, when it is compared with long-term erythromycin use.Due to sparse available evidence about the safety and effectiveness of macrolides to treat H ducreyi infection in people with HIV, these results should be taken with caution.

Haemophilus ducreyi as a cause of skin ulcers in children from a yaws-endemic area of Papua New Guinea: a prospective cohort study.
Skin infections with ulceration are a major health problem in countries of the south Pacific region. Yaws, caused by Treponema pallidum subspecies pertenue and diagnosed by the presence of skin ulcers and a reactive syphilis serology, is one major cause, but this infection can be confused clinically with ulcers due to other causative agents. We investigated T pallidum pertenue and another bacterium known to cause skin infections in the Pacific islands-Haemophilus ducreyi-as causes of skin ulceration in a yaws-endemic region. Additionally, we identified specific signs and symptoms associated with these causative agents of cutaneous ulcers and compared these findings with laboratory-based diagnoses. ⋯ Newcrest Mining Company.

Haemophilus ducreyi is a fastidious gram-negative bacillus that causes the sexually transmitted infection chancroid. Chancroid is a major genital ulcerative disease in Africa, Southeast Asia, the Caribbean, and Latin America and is of increasing concern in the United States. Genital ulcerative disease and chancroid in particular have been associated with facilitating the transmission of human immunodeficiency virus. ⋯ There has been renewed interest in understanding the pathogenesis of H. ducreyi. In vitro and in vivo models have been developed to help identify important virulence determinants. Through the use of biochemical and molecular techniques, macromolecular components that may be important in virulence have been identified.
