The number of disorders associated with congenital or acquired asplenia and functional hyposplenism has increased substantially over the past couple decades. Previously, screening for asplenia and hyposplenism was a barrier to identifying patients at risk. Recent methods for measuring splenic function have emerged as accurate and reliable. Identifying patients prevents overwhelming postsplenectomy infection or invasive pneumococcal disease. Approaches to protect patients with asplenia or hyposplenism include patient education of risks and signs/symptoms of infection, vaccination, and antibiotic prophylaxis. Physicians have...

Evaluation of antibodies produced after immunization is central to immune deficiency diagnosis. This includes assessment of responses to routine immunizations as well as to vaccines administered specifically for diagnosis. Here, we present the basic concepts of the humoral immune response and their relevance for vaccine composition and diagnosis of immune deficiency. Current vaccines are discussed, including nonviable protein and glycoprotein vaccines, pure polysaccharide vaccines, polysaccharide –protein conjugate vaccines, and live agent vaccines. Diagnostic and therapeutic applications of vaccine antibody measurem...

Authors: Naik R, Peden K Abstract Developing traditional viral vaccines for infectious diseases usually takes years, as these are usually produced either by chemical inactivation of the virus or attenuation of the pathogen, processes that can take considerable time to validate and also require the live pathogen. With the advent of nucleic-acid vaccines (DNA and mRNA), the time to vaccine design and production is considerably shortened, since once the platform has been established, all that is required is the sequence of the antigen gene, its synthesis and insertion into an appropriate expression vector; importantly...

Mosquito bites may be a nuisance, but fortunately, in the U.S., they tend to amount to nothing more than that. Upon being bitten, most Americans experience a bit of swelling and itchiness, and nothing more. However, there are exceptions to this, including stronger allergic reactions to bites and cases of mosquito-borne illness.  Insect and arachnid bites, including ticks, account for approximately 2,000 cases of malaria and 30,000 cases of Lyme disease in the U.S. annually. In addition, millions of people worldwide die of malaria each year. It is helpful to protect yourself against insect bites, not only to avoid pesk...

Discussion Dengue is an important arboviral infection that affects about 40% of the world population. It is found mainly in topical and subtropical areas of the world mainly in developing countries but it range is spreading including the United States. A review of common arboviruses can be found here. It is a flaviavirus with 4 distinct serotypes named DENV-1 through DENV-4 and is spread by A. aegypti a day biting mosquito. Infection with one serotype confers immunity to that serotype but not the others. It does offer some protection for cross-infection but this only lasts a few months. Incubation period is 3-14 days with ...

Date: August 26, 2019 Issue #:  1579Summary:  Use of insect repellents is strongly recommended by the Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) to prevent infections transmitted by mosquitoes and ticks. Insect repellents applied to exposed skin should be used in conjunction with other preventive measures such as wearing pants and long-sleeved shirts, and avoiding outdoor activities during peak mosquito-biting times. Mosquitoes can transmit Zika, chikungunya, dengue, West Nile, eastern equine encephalitis, and yellow fever viruses, as well as...

For most of us, springtime marks the return of life to a dreary landscape, bringing birdsong, trees in bud, and daffodils in bloom. But if you work for the Centers for Disease Control and Prevention (CDC), the coming of spring means the return of nasty diseases spread by ticks and mosquitoes. The killjoys at CDC celebrated the end of winter with a bummer of a paper showing that infections spread by ticks doubled in the United States from 2004 to 2016. (Tick populations have exploded in recent decades, perhaps due to climate change and loss of biodiversity.) Lyme disease The most common infection spread by ticks in the US i...

Date:  July 4, 2016 Issue #:  1498 Summary:  Use of insect repellents is strongly recommended by the CDC and the EPA to prevent Zika virus infection and other mosquito- and tickborne diseases. Mosquitoes can transmit chikungunya, dengue, West Nile, and yellow fever viruses, and malaria. Ticks can transmit Lyme disease and rickettsial diseases such as Rocky Mountain spotted fever.
