Schistosomiasis More Debilitating Than Previously Estimated

05.03.2008
Public health researchers have found that the health burden of an Asian strain of the parasitic flatworm schistosomiasis is much more debilitating than previously thought.

In a new study, published March 5 in the open-access journal PLoS Neglected Tropical Diseases, the researchers calculate that the impact of symptoms associated with schistosomiasis japonica is 7 to 46 times greater than current global estimates.

This is the first strain-specific study of the global disease burden of schistosomiasis, which is one of the most common infections in the world, infecting an estimated 207 million people in 76 primarily developing countries. The study is part of a growing body of evidence that the serious health effects of this common parasitic disease are far greater than previously estimated.

“Schistosomiasis has a detrimental impact on nutrition and growth and development and can lead to major organ damage and death,” said lead study author Julia Finkelstein (Harvard School of Public Health, Boston, USA). “Current measures may severely underestimate the disability-related impact of the infection and need to be revised.”

Through its Global Burden of Disease project, the World Health Organization (WHO) estimates the incidence, prevalence, severity and duration of over 130 major causes of illness, injury and death worldwide. This project is based on a statistical measure called the disability-adjusted life year (DALY), which is the number of years of life lost due to premature death and the years lost due to disability. Policymakers use the data to help determine funding for prevention and treatment programs as well as research.

According to WHO estimates, the disease burden from schistosomiasis is low, with a 0.005 DALY score on a scale of 0 (perfect health) to 1 (death). But the global burden of schistosomiasis has not been examined in more than a decade.

In this new study, the researchers focused on evaluating schistosomiasis japonica, one of the three main forms of schistosomiasis, found in China and the Philippines. The team used data from the scientific literature and a decision-model approach to re-examine the disease burden. Finkelstein and her team arrived at a substantially higher disability impact for schistosomiasis japonica. Instead of a 0.005 score, they arrived at estimates of 0.098 to 0.186.

In a related Expert Commentary article also published in PLoS Neglected Tropical Diseases, Dr. Charles King (Case Western Reserve University, Cleveland, USA) , who was not involved in the study, predicted that, “Ultimately, these new measures of schistosomiasis-associated disability will translate into a greater priority to control schistosomiasis.” Incorporating such new approaches and findings with old estimates will, he said, “be essential to providing a balanced and fair assessment of neglected tropical diseases, and for properly setting disease control priorities for these disabling diseases of poverty.”

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
