A little more than three years ago a medical team from Berlin published the results of a unique experiment that astonished HIV researchers. The German group had taken bone marrow--the source of the body’s immune cells--from an anonymous donor whose genetic inheritance made him or her naturally resistant to HIV. Then the researchers transplanted the cells into a man with leukemia who had been HIV-positive for more than 10 years. Although treatment of the patient’s leukemia was the rationale for the bone marrow transplant therapy, the group also hoped that the transplant would provide enough HIV-resistant cells to control the man’s infection. The therapy exceeded the team’s expectations. Instead of just decreasing the amount of HIV in the patient’s blood, the transplant wiped out all detectable traces of the virus from his body, including in multiple tissues where it could have lain dormant. The German researchers were so surprised by the spectacularly positive results that they waited nearly two years before publishing their data. [More]

Antidepressants restore well-being to many people, but sometimes at the cost of such side effects as weight gain or loss of interest in sex. And these side effects can be just part of the frustration. As Robin Marantz Henig wrote in " Lifting the Black Cloud ," in the March issue of Scientific American , the drugs that have long dominated the market--the selective serotonin reuptake inhibitors (SSRIs) and the serotonin and norepinephrine reuptake inhibitors (SNRIs)--"do not help everyone and eventually fail in more than a third of users. A pill that seems to be working today might well stop helping tomorrow. And the drugs can take several weeks to start having a marked effect." Equally disturbing, some major pharmaceutical houses, such as GlaxoSmithKline , are pulling back from developing psychiatric medicines. [More]

A young woman who calls herself blue­berryoctopus had been taking anti­depressants for three years, mostly for anxiety and panic attacks, when she recounted her struggles with them on the Web site Experience Project. She said she had spent a year on Paxil, one of the popular SSRIs (selective serotonin reuptake inhibitors), but finally stopped because it destroyed her sex drive. She switched to Xanax, an ­antianxiety drug , which brought back her libido but at the cost of renewed symptoms. Then Paxil again, then Lexapro (another SSRI), then Pristiq, a member of a related class of antidepressants, the SNRIs (serotonin and norepinephrine reuptake inhibitors). At the time of the post, she was on yet another SSRI, Zoloft, plus Wellbutrin (a cousin of SNRIs that affects the activity of dopamine as well as norepinephrine), which was intended to counteract the sexual side effects of Zoloft. “I don’t notice much of a difference with the Wellbutrin, but I’m on the lowest dose now,” she wrote. “I’m going back to my psychiatrist next week, so maybe he’ll up it. Who knows.” [More]

Inevitably, year-end lists invite plenty of debate and criticism, and Scientific American 's is no exception.

The patient had endured 20 years of pain: her calves had turned into two bricks,  and she now had trouble walking. A slew of doctors had failed to treat, let alone diagnose, her unusual condition. So when her x-rays finally landed on William A. Gahl’s desk at the National Institutes of Health, he knew immediately that he had to take her case.Gahl is the scientist and physician who leads the Undiagnosed Diseases Program, which tries to unravel the underlying causes of, and find therapies for, mysterious maladies and known but rare conditions. Louise Benge’s x-rays had revealed that blood vessels in her legs and feet bore a thick coat of calcium that restricted blood flow. Benge’s sister, Paula Allen, along with several other members of the family, also shared the disorder. Over the course of several months Gahl identified the genetic root of the disorder--a mutation in a gene that regulates calcium--and he went on to propose a treatment with drugs already on the market. He continues to assess the treatment’s value. [More]

Exact details of the alternative natural and traditional therapies tried by Steve Jobs before he underwent surgery in 2004 and eventually died of pancreatic cancer earlier this month have not been disclosed. (A representative from Apple declined to comment on any aspect of the Apple co-founder's illness.) He reportedly restricted his diet to just fruits or just fruits and vegetables, tried out something called hydrotherapy and consulted psychics. In any case, a mounting body of scientific and anecdotal reports provides compelling evidence about the potential impact, both positive and negative, of so-called complementary practices on the health and longevity of cancer patients following their diagnosis. And, although Jobs's unconventional early-treatment choices may not have done much to stave off the spread of deadly cancer cells in his case, they provide an opportunity to discuss what makes cancer grow and how to stop it.Jobs had a rare form of pancreatic cancer known as pancreatic neuroendocrine tumor (pNET). Accounting for about 1 percent of all pancreatic cancers, pNET is a cancer of the endocrine cells, known clinically as the islets of Langerhans, which exist in small clusters throughout the pancreas. These cells produce hormones such as insulin, which lowers blood sugar, and glucagon, which increases it. [More]

From Nature magazine.When it was first used in the 1990s to treat an immune deficiency, gene therapy -- treating diseases by correcting a patient's faulty genes -- was touted as a breakthrough that was likely to cure scores of hereditary diseases. But when 18-year-old Jessie Gelsinger died in 1999 after having a corrected gene injected to treat his liver disease, the field became wary, and researchers found it difficult to fix the problems associated with the technique.

No organ in the human body is as resistant to study as the brain. Whereas researchers can examine living cells from the liver, lung and heart, taking a biopsy of the brain is, for many reasons, more problematic.The inability to watch living human brain cells in action has hampered scientists in their efforts to understand psychiatric disorders. But researchers have identified a promising new approach that may revolutionize the study and treatment of conditions such as schizophrenia, autism and bipolar dis­order. A team led by researchers at the Salk Institute for Biological Studies in La Jolla, Calif., took skin cells from a patient with schizophrenia, turned them into adult stem cells and then grew those stem cells into neurons. The resulting tangle of brain cells gave neuroscientists their first real-time glimpse of human schizophrenia at the cellular level. Another team, from Stanford University, converted human skin cells directly into neurons without first stopping at the stem cell stage, potentially making the process more efficient. The groups published their results recently in Nature ( Scientific American is part of Nature Publishing Group). [More]

In 1989 when scientists discovered the defective gene that causes cystic fibrosis, a serious hereditary disorder that primarily strikes children of European descent, it seemed as though a long-hoped-for cure might soon follow. After all, tests in many laboratories showed that providing normal copies of the gene should enable patients to make healthy copies of the protein specified by the gene. If successful, that feat would go a long way toward restoring health in the tens of thousands of people around the world who suffered from cystic fibrosis and typically died in their late 20s. (Half of all patients now live to their late 30s or beyond.) The question was whether researchers would be able to reliably insert the correct gene into the proper tissues in patients’ bodies to rid them of the illness forever.That task proved harder than anyone had believed. Although scientists successfully engineered viruses to ferry copies of the correct gene into patients’ cells, the viruses did not do the job well. By the late 1990s additional unexpected complications made it increasingly obvious that another approach to addressing the fundamental problem in cystic fibrosis would need to be found. [More]

Chronic pain affects at least one in three adults in the U.S., which is more than the sum total of those with heart disease, cancer and diabetes combined. For many of these 116 million Americans, their pain is severe and eludes available treatments. In addition to the human suffering, the monetary cost of medical treatment and lost productivity has reached $635 billion a year. [More]
