Statins given early decrease progression of kidney disease

First positive finding for children with serious form of kidney disease

2014-05-08

(Press-News.org) AURORA, Colo. (May 8, 2014) - Results from a study by University of Colorado School of Medicine researchers show that pravastatin, a medicine widely used for treatment of high cholesterol, also slows down the growth of kidney cysts in children and young adults with autosomal dominant polycystic kidney disease (ADPKD).

ADPKD is the most common potentially lethal hereditary kidney disease, affecting at least 1 in 1000 people. ADPKD is characterized by progressive kidney enlargement due to cyst growth, which results in loss of kidney function over time. At one time, ADPKD was termed "adult" polycystic kidney disease but researchers are finding that clinical manifestations may be evident in childhood and even in utero. This strongly suggests that earlier intervention in childhood may have the greatest long term effect on the progression of the disease.

"Based on our findings, we strongly recommend consideration of pravastatin use in ADPKD children and young adults unless there is a medical reason against taking a statin as determined by the patients' doctor," says the co-principal investigator Melissa A. Cadnapaphornchai, MD, from CU School of Medicine's departments of pediatrics & medicine, who conducted the study with Robert W. Schrier, MD, at the CU School of Medicine. "This is very exciting news as this is the first medication shown to help control kidney disease in ADPKD children."

The three-year study began with 110 children/young adults ages 8 to 22 years with ADPKD and finished with 92 participants. Each participant was randomized to receive either pravastatin or placebo completely by chance by a procedure similar to the toss of a coin. Treatment with pravastatin was associated with no significant side effects. However, it should not be used during pregnancy

The researchers emphasize that pravastatin is not FDA-approved for the treatment of ADPKD; therefore, it is essential that patients discuss the potential risks and benefits of treatment, including possible psychosocial and financial implications, with their doctor.

INFORMATION: This study Effect of Pravastatin on Total Kidney Volume, Left Ventricular Mass Index, and Microalbuminuria in Pediatric Autosomal Dominant Polycystic Kidney Disease has been published in the Clinical Journal of American Society of Nephrology, Volume 9, Number 5, May 2014.

Mummy-making wasps discovered in Ecuador

2014-05-08

Some Ecuadorian tribes were famous for making mummified shrunken heads from the remains of their conquered foes. Field work in the cloud forests of Ecuador by Professor Scott Shaw, University of Wyoming, Laramie, and colleagues, has resulted in the discovery of 24 new species of Aleiodes wasps that mummify caterpillars. The research by Eduardo Shimbori, Universidade Federal de São Carlos, Brazil, and Scott Shaw, was recently published in the open access journal ZooKeys. Among the 24 new insect species described by Shimbori and Shaw, several were named after famous people ...

NASA sees system 91B lingering over southwestern India

2014-05-08

The tropical low pressure area known as System 91B has been making a slow northerly crawl while sitting inland in southwestern India, and NASA's Terra satellite captured a visible image of the struggling storm that showed half of it is over the Northern Indian Ocean. NASA's Terra satellite passed over System 91B over southwestern India and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image on May 8 at 05:40 UTC/1:40 a.m. EDT. The despite having a poorly defined low-level circulation center on infrared imagery, the circulation ...

Experimental antibody shows early promise for treatment of childhood tumor

2014-05-08

Tumors shrank or disappeared and disease progression was temporarily halted in 15 children with advanced neuroblastoma enrolled in a safety study of an experimental antibody produced at St. Jude Children's Research Hospital. Four patients are still alive after more than two-and-a-half years and without additional treatment. Findings from the Phase I study were published recently online and will appear in the May 10 edition of the Journal of Clinical Oncology. The results prompted St. Jude to expand clinical trials of the monoclonal antibody hu14.18K322A to include patients ...

Wake Forest Baptist finds success with novel lung cancer treatment

2014-05-08

WINSTON-SALEM, N.C. – May 8, 2014 – An old idea of retreating lung tumors with radiation is new again, especially with the technological advances seen in radiation oncology over the last decade. The Comprehensive Cancer Center of Wake Forest Baptist Medical Center is one of only a handful of cancer centers that is attempting to give lung cancer patients out of treatment options a chance to keep the cancer at bay. For these patients, hope lies in a second course of treatment – repeat radiation. Two complementary papers published back-to-back recently in the journal Radiotherapy ...

Health screening for low-income women under health care reform: Better or worse?

2014-05-08

New Rochelle, NY, May 8, 2014—When Massachusetts enacted its own statewide health insurance reform in 2006, low-income women transitioned from receiving free, federally subsidized screening for breast and cervical cancer and cardiovascular disease risk to an insurance-based payment system. The effects on screening rates in this vulnerable population are explored in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website at http://online.liebertpub.com/doi/full/10.1089/jwh.2013.4612. A ...

This FIB doesn't lie: New NIST microscope sees what others can't

2014-05-08

Microscopes don't exactly lie, but their limitations affect the truths they can tell. For example, scanning electron microscopes (SEMs) simply can't see materials that don't conduct electricity very well, and their high energies can actually damage some types of samples. In an effort to extract a little more truth from the world of nanomaterials and nanostructures, researchers at the National Institute of Standards and Technology (NIST) have built the first low-energy focused ion beam (FIB) microscope that uses a lithium ion source.* The team's new approach opens up ...

Oregon researchers capture handoff of tracked object between brain hemispheres

2014-05-08

EUGENE, Ore. -- When tracking a moving object, the two halves of the human brain operate much like runners successfully passing a baton during a relay race, says a University of Oregon researcher. In a study online ahead of print in Current Biology, electroencephalogram (EEG) measured brainwaves from healthy young adults revealed how information about an attended object -- one being watched closely -- moves from one brain hemisphere to the other. Such handoffs are necessary because the human visual system is contralateral; objects on the left side of space are processed ...

New grasshopper species named after Grammy winner

2014-05-08

A newly discovered grasshopper by University of Central Florida scientists now bears the name of Grammy-award winning singer and activist Ana Lila Downs Sanchez. The scientists named the new species discovered on the side of a mountain road near Oaxaca, Mexico, after the Mexican-American singer as a nod to her efforts to preserve indigenous culture and penchant for wearing colorful, local costumes as part of her performances. "It was primarily Paolo's idea to name the grasshopper after the singer" said Derek Woller, one of the authors of the paper referring to colleague ...

Obesity drug failing patients due to lack of education about side-effects

2014-05-08

A new study, published today in the Journal of Health Psychology, found that patients who gained weight 18 months after taking Orlistat attributed their weight-loss failure either to the side effects which have prevented them from sticking to the medication or felt that the medication simply had not worked. The team from the University of Surrey also found that participants described a series of barriers to weight loss including psychological and physical health issues, relationships and the make-up of their bodies. They also described a number of alternative methods ...

Urine test best detects alcohol use in liver transplant candidates, recipients

2014-05-08

Researchers from Italy confirm that urinary ethyl glucuronide (uEtG) accurately detects alcohol consumption in liver transplant candidates and recipients. The study published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, suggests that a combination of uEtG and the Alcohol Use Disorders Identification Test for alcohol consumption (AUDIT-c) are best in alerting doctors to alcohol consumption by patients undergoing evaluation for liver transplantation or who have received ...
