Although it is evident that zoster vaccination reduces postherpetic neuralgia (PHN) risk by reducing herpes zoster (HZ) occurrence, it is less clear whether the vaccine protects against PHN among patients who develop HZ despite previous vaccination. ⋯ Among persons experiencing HZ, prior HZ vaccination is associated with a lower risk of PHN in women but not in men. This sex-related difference may reflect differences in healthcare-seeking patterns and deserve further investigation.

Kaposi sarcoma herpesvirus (KSHV)-associated multicentric Castleman disease (MCD) is a lymphoproliferative inflammatory disorder commonly associated with human immunodeficiency virus (HIV). Its presentation may be difficult to distinguish from HIV and its complications, including lymphoma. Novel imaging strategies could address these problems. ⋯ KSHV-MCD activity is associated with (18)F-FDG PET abnormalities of the lymph nodes, spleen, marrow, and salivary glands. These findings have clinical implications for the diagnosis and monitoring of KSHV-MCD and shed light on its pathobiologic mechanism.

Study of meningococcal carriage is essential to understanding the epidemiology of Neisseria meningitidis infection. ⋯ The prevalence of meningococcal carriage in the African meningitis belt is lower than in industrialized countries and is very diverse and dynamic, even in the absence of vaccination.

The ongoing outbreak of Ebola in West Africa has raised a general awareness that at present there are no Ebola-specific medical countermeasures (MCMs) with proven effectiveness. This paper recapitulates discussions held at the 6th International Filovirus Symposium in March 2014 as well as the subsequent design of a randomized clinical trial design for treating Ebola virus-infected patients evacuated from West Africa to the United States. ⋯ Developers and sponsors of these candidate products were strongly encouraged to prepare pre-IND packets and submit pre-IND meeting requests to the Food and Drug Administration. Some of these investigational products have already been used under emergency authorizations to treat patients in Africa as well as patients evacuated to the United States or Western Europe.

The current Ebola virus (EBOV) outbreak has highlighted the troubling absence of available antivirals or vaccines to treat infected patients and stop the spread of EBOV. The EBOV glycoprotein (GP) plays critical roles in the early stage of virus infection, including receptor binding and membrane fusion, making it a potential target for the development of anti-EBOV drugs. We report the identification of 2 novel EBOV inhibitors targeting viral entry. ⋯ We have identified 2 novel EBOV inhibitors, MBX2254 and MBX2270, that can serve as starting points for the development of an anti-EBOV therapeutic agent. Our findings also highlight the importance of NPC1-GP interaction in EBOV entry and the attractiveness of NPC1 as an antifiloviral therapeutic target.
