Nepalese researchers identify cost-effective treatment for drug-resistant typhoid

28.06.2007
New research carried out by researchers in Nepal has shown that a new and affordable drug, Gatifloxacin, may be more effective at treating typhoid fever than the drug currently recommended by the World Health Organisation. The study, funded by the Wellcome Trust, has implications for the treatment of typhoid particularly in areas where drug resistance is a major problem. The results are published today in the open access journal PLoS ONE.

Enteric fever, of which typhoid fever is the most common form, is a major disease affecting the developing world, where sanitary conditions remain poor. The best global estimates are of at least 22 million cases of typhoid fever each year with 200,000 deaths. Drug resistance is becoming a major problem and treatment is becoming increasingly difficult, leading to patients taking longer to recover, suffering more complications and continuing to spread the disease to their family and to their community.

Clinical investigators based at Patan Hospital Lalitpur in Kathmandu, Nepal, and the Oxford University Clinical Research Unit in Vietnam have completed a study to see if they can improve the treatment for patients with typhoid fever. Kathmandu has been termed the typhoid fever capital of the world as a result of this disease remaining so common.

“Typhoid fever is a major problem in Nepal and in the developing world and drug-resistant strains are making it even more difficult to tackle," says Dr Buddha Basnyat, senior investigator on the study. "The currently recommended treatment, Cefixime, is relatively expensive and must be administered for a longer duration than is ideal. Clearly there is an urgent need for a treatment that is cost-effective and easy to administer."

The results of the study show that a cost-effective new fluoroquinolone drug, Gatifloxacin, may be a better treatment for enteric fever than Cefixime, which is currently recommended by the World Health Organisation. In addition, Salmonella enterica Typhi and Salmonella enterica serovar Paratyhpi A, the two most common bacteria to cause enteric fever, do not show resistance to Gatifloxacin, unlike for other fluoroquinolones.

"We have shown that Gatifloxacin may be better than an established drug used by many doctors around the world," says Dr Basnyat. "There is currently no resistance to the drug, and at just over US$1 dollar for a seven day treatment course is relatively inexpensive."

"This is an important study with major implications for treating disease widespread in the developing world," says Professor Jeremy Farrar from the Oxford University Clinical Research Unit in Vietnam. "It also shows the major contribution that clinical investigators in Nepal, with the experience and knowledge gained from access to thousands of patients, can help make to improving treatment for our patients and to global health.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
