Roseola News and Research

RSS

Roseola is a viral infection affecting young children. It causes a skin rash of a pinkish color after the child has been racked by high fever for a couple of days. The multiple rash spots tend to turn white when touched. Individual rashes may have lighter rings of pink around them like halos. The spots start out on the trunk of the body, then spread to the neck, face, arms, and legs. It is a fairly common disease in children between 3 months to 4 years of age.

Study reveals new way viruses trigger autoimmunity

Autoimmune diseases such as rheumatoid arthritis and Type 1 diabetes are thought to arise when people with a genetic susceptibility to autoimmunity encounter something in the environment that triggers their immune systems to attack their own bodies.

Researchers develop vaccine for human herpesvirus 6B

A research group led by Professor MORI Yasuko (of the Division of Clinical Virology, Center for Infectious Diseases, Kobe University Graduate School of Medicine) has revealed that the HHV-6B glycoprotein complex gH/gL/gQ1/gQ2 is an effective vaccine candidate for human herpesvirus 6B (HHV-6B).

New method to separate two variants of common herpes virus linked to multiple sclerosis

Researchers at Karolinska Institutet have developed a new method to separate between two different types of a common herpes virus that has been linked to multiple sclerosis.

Researchers find genes from 'fossil' virus in human DNA to be active

Genes from a virus that was stitched into the human genome thousands of years ago are active, producing proteins in the human brain and other tissues, according to researchers at the University of Washington School of Medicine and the Laval University School of Medicine in Quebec, Canada.

Ubiquitous human herpesvirus 6 may play key role in brain diseases like multiple sclerosis

The ubiquitous human herpesvirus 6 (HHV-6) may play a critical role in impeding the brain's ability to repair itself in diseases like multiple sclerosis.

HHV-6A human herpesvirus infects uterus lining of women with unexplained infertility

A new study has found that the little-known member of the human herpesvirus family called HHV-6A infects the lining of the uterus in 43% of women with unexplained infertility but cannot be found in uterine lining of fertile women. The study was conducted by investigators at the University of Ferrara, Italy.

Loyola pediatrician reveals signs and symptoms of childhood rashes

Sniffles, stomach bugs, fever and sore throats are often associated with viruses, but rashes are common in children with viral infections as well.

Study: Apoptosis triggers alternate replication pathway in HHV

Washington, DC-Researchers from Children's National Medical Center have found that an alternate, "escape" replication process triggered by apoptosis-the process of cell death or "cell suicide"-appears to be common in human herpesviruses (HHV).

Roseola virus behind one-third of febrile seizures in young children

Researchers have discovered that infection with two of the roseola viruses, which are responsible for a common childhood rash, appear to increase a child’s risk for prolonged seizures and fever and may increase future temporal lobe epilepsy risk.

Study strengthens link between HHV-6B and mesial temporal lobe epilepsy

A ten-year NIH-funded study has determined that a third of infants with prolonged seizures and fever suffer from either a new or reactivated roseola virus infection. Roseola viruses are the cause of the common childhood rash, but can also cause limbic encephalitis, a condition that frequently progresses to epilepsy. Investigators discovered one of the roseola viruses, human herpesvirus-6B (HHV-6B) in the blood of 32% of 169 infants with prolonged seizures, a condition known as status epilepticus.

Roseola virus accounts for one third of febrile status epilepticus cases

New research shows that human herpesviruses (HHV)-6B and HHV-7, commonly know as roseola virus), account for one third of febrile status epilepticus (FSE) cases. Results of the FEBSTAT prospective study now available in Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy (ILAE), suggest that HHV-6B may be involved in the development of epilepsy and further research is urgently needed.

Raltegravir could be valid target against all Herpesviridae

Scientists at the Institute for Research in Biomedicine (IRB Barcelona) headed by the coordinator of the Structural and Computational Biology Programme, Miquel Coll, have published a new study that demonstrates that raltegravir, the drug approved in 2007 for the treatment of AIDS that is sold by Merck under the name Isentress, cancels the function of an essential protein for the replication of one kind of herpes virus.

USF study: HHV-6 causes permanent infection by inserting its DNA into human chromosomes

Human herpesvirus 6 (HHV-6) infects nearly 100 percent of humans in early childhood, and the infection then lasts for the rest of a person's life. Now, a team led by Peter Medveczky, MD, a professor in the Department of Molecular Medicine at the University of South Florida, has discovered that in some individuals, HHV-6 causes such a permanent infection by inserting or "integrating" its DNA into human chromosomes.
