Exploitation of Neisseria meningitidis Group B OMV Vaccines Against N. gonorrhoeae to Inform the Development and Deployment of Effective Gonorrhea Vaccines

In this study it was assumed that there was no immunity following resolution of natural infection. The modeling demonstrated that a vaccine of moderate efficacy could have a significant impact on the prevalence of gonorrhea if strategically implemented (23). While encouraging it does, of course, depend on the availability of a vaccine. From Ecological Data to Evidence The epidemiological evidence from Cuba, Brazil, and New Zealand demonstrates that N. meningitidis OMV vaccines are possibly able to provide some broader protection against meningococcal disease (17, 24), particularly in older children and adults (25). These observations led to the hypothesis that they may affect a more distantly related bacterium. Examination of surveillance data clearly show a marked decline in the incidence of gonorrhea in Cuba following implementation of the VA-MENGOCBC (Figure 1). The pattern of decline in incidence for gonorrhea contrasts with syphilis and genital warts for which incidences have remained the same (8). This phenomenon was also observed in NZ, where a decline in reported gonorrhea cases during and shortly after use of the tailor made meningococcal Group B OMV vaccine MeNZB is evident (Figure 2). Like Cuba, no other sexually transmitted infections (STIs) described in the national surveillance reports declined during that period (26). While purely ecological, these observations suggested that N. meningitidis OMV vaccines might offer cross protection against gonorrhea. FIGU...

Authors: Hammerschlag MR, Sharma R Abstract INTRODUCTION: Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline. AREAS COVERED: Literature on treatment of rectal C. trachomatis from 2000 through May 2020 was searched using PubMed. Retrospective and observational studies were identified documenting the frequency and t...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...
