Early Use of Immunosuppressive Drugs for Early Crohn’s PatientSo far the strategy of treating patients, who were newly diagnosed with Crohn’s disease, was the use of corticosteroids to control abdominal pain and bloody diarrhea. The conventional mode of treatment consisted of a “step-up”treatment: after corticosteroids the use of immunosuppressants and finally antibody treatment would follow to curb the inflammatory response. International data which were published in the Lancet (February 23 issue) points to a safer and more effective treatment protocol. It consists of a “top-down” approach rather than of the conventional “step-up” approach. Patients receive immunosuppression early in the form of azathioprine and also the antibody infliximab, known as Remicade. Another study examined patients who were on maintenance therapy with adalimumab (Humira). They experienced sustained improvements in the symptoms that are associated with Crohn’s disease. After 4 weeks of induction therapy with the medication patients with mild and severe depression had improved to such an extent that they returned to the normal range. They were also assessed regarding fatigue and after treatment they showed a significant improvement in their daily functioning. The two treatment protocols were compared in a trial involving 129 patients with Crohn’s disease who had no previous treatment. At the end of the trial the researcher found that 65% of the group that had received the “top-down” treatment was symptom free after 26 weeks of treatment. Contrary to this only 36% of the “step-up” patients went into remission during the same time. When the patients were examined after 1 year, 62% of the “top-down” group was still symptom free, but only 42% of the “step-up” group had no symptoms. Dr. Brian Feagan of the University of Western Ontario coordinated this trial involving international sites in Belgium, Holland and Germany. He points out that the newly diagnosed Crohn’s disease patient that has the worst prognostic signs will benefit of this form of treatment. The top-down modality also is safer, as it protects the patient from high exposure to steroids. Similar results were demonstrated in patients with rheumatoid arthritis. The results of these trials and Dr. Feagan’s research suggest that the top-down treatment option could also give the best chance to patients with other chronic autoimmune diseases such as ulcerative colitis.
Tree Pollen Connected With Mood DisordersSeasonal affective disorder (SAD) does have its grip on people who react to a lack of sunlight in the winter month. As a result depression in the winter season is not uncommon. Some people just report it as feeling” down” and”tired” or report a lack of energy. Despite all the reports about SA, epidemiological studies have shown that the rate of depression is not the highest in dreary months like January or February but it spikes in the months of April and June. Dr.Teodor Postolache, a psychiatrist at the University of Maryland made a recent presentation at a meeting of the American Acadamy of Allergy, Asthma and Immunolgy delving into the reason for this finding. He compared the exposure of tree pollen which triggers a cytokine release to a tsunami.Virtually no outdoor allergens are present in the winter months, but with the release of tree pollen people who are vulnerable to allergies are exposed to massive amounts of allergens. The released cytokines may affect brain function and behaviour, resulting ultimately in changed cortisol levels and an altered serotonin metabolism. After breathing the cytokines are already released in the nose,and they can continue their action in the prefrontal brain area where the centers for mood, anxiety and impulsivity are located. Dr. Postolache and his colleagues confirmed that individuals with a history of allergy and asthma had a 2.5 fold of suicide compared to controls and those with allergic rhinitis haad a 1.7 fold higher risk. For the first time it could also be demonstrated that cytokine levels in suicide victims were significantly elevated in the orbitofrontal cortex, the brain area that affects mood. Intranasal corticosteroids in the form of nosedrops can bring significant relief to allergy sufferers, and Dr. Postolache and his team will closer exmine the benefits of intranasal corticosteroids in a clinical study.Whereas systemic corticosteroids have shown a negative impact on mood disorders and depression, the local application of a nasal spray or drops is geared to abolish the pathways from the nose to the brain for the inflammatory cytokines.
Cancer Risk Higher For Hairstylists or BarberA report coming from the International Agency for Research on Cancer which was recently published in the Lancet Oncology reported that working as a hairstylist or barber does have occupational hazards. A small but consistent risk for bladder cancer was noted in male hairdressers and barbers. As there were no reliable data on duration and periods of exposure the data are considered to be limited evidence of a cancer risk. Some carcinogenic substances have been present in modern hair dyes. These particular colorants were discontinued in the 1970’s after positive cancer tests in mice and rats were seen. The researchers also examined the personal use of hair dyes, but could not show an adequate evidence that hair dyes would be cancerogenic.As a result they also could not definitely judge that the dyes carried a cancer risk. Other chemicals that like hair dyes belong into the group of aromatic amines were assessed by the researchers. Ortho-toluidine which is used in the production of dyes, pigments and rubber chemicals is now classified as a carcinogenic substance to humans, as is the chemical called MOCA (4,4-methylene bis (2-chloroaniline))which is used as a curing substance in the plastics industry. The Lancet Oncology - Volume 9, Issue 4 (April 2008) Glucose and Colorectal Cancer Are No Sweet DealIt has been noted in various publications that insulin resistance carries a host of health risks: aside from type 2 diabetes, there is cardiovascular disease. Also high insulin levels are associated with growth hormone like substances in the body. These substances are contributing to the development of some cancers. Researchers from Minnesota and Maryland examined 375 individuals with recurrent polyps and the identical number without recurrent adenoma. They followed the course of the patients for 4 years. In their study they looked at fasting serum. Patients who were found to have the highest levels of both insulin and glucose in their serum were at an approximately 50% higher risk of colorectal cancer recurrence. The strongest risk factors were elevated glucose levels. The individuals with the highest glucose levels also tended to be slightly older, have a higher waist to hip ration and a higher body mass index. These results do point out the necessity of keeping a close tab on glycemic control in person with a history of colorectal polyps. It also is evident that consuming foods with a low to medium glycemic index will help to reduce the risk for colonic cancers. The Medical Post, April 1, 2008, page 21 When Kid Are Migraine SufferersIt is often assumed that migraine headaches are reserved for people with a family history of migraines and that those who are afflicted by those disabling headaches are usually adults. When a child has the symptoms of migraine headaches it is usually a source of grave concern to the parents. Dr. Lewis reported about his findings at a meeting which was sponsored by Rady Children’s Hospital. He has seen many young persons who suffer of headaches and pointed out that the greatest fear of the patient and the parents, is the thought of a developing brain tumor. If a patient has been having headaches for half a year or two years and has had an entirely normal neurological exam, Dr. Lewis can reassure the patient that there is no brain tumor. Breaking the vicious cycle of fear by reassurance often lifts a load of the patient’s back and things may settle down. About 11% of children in the age group of 5 to 15 years have migraine type headaches. The incidence has a peak at 12 years in boys and at 14 years in girls.Migraines have different criteria than headaches: there are at least 5 lifetime attacks that have a least two of the following symptoms: severe aches on both sides of the head, the front or on one side only, throbbing aches, moderate to severe pain that gets worse with activity. At least one symptom of the following has to be present: either light sensitivity, sensitivity to noise, nausea and vomiting. Dr. Lewis reports that proper sleep habits can make a difference. Too little, too much or inconsistent sleep is closely associated with the frequency of migraines. He cited the example of a sixteen year old who started having migraines after school ended at the end of June. She stayed up late and slept till noon. Once she returned to a regular sleep cycle she did a lot better. Eating patterns can play a role too. One of the common stories is the student skipping lunch and developing a headache about an hour later. Other migraine triggers can be sensitivities to certain foods, altitude changes, weather, motion sickness on a trip, excitement, dehydration and learning problems. Dr. Lewis reported that many of the very young patients age 4 to 5 with migraines may have attention-deficit hyperactivity disorder. If the performance problems are addressed headaches will resolve in 80 to 90% of the time. Headaches can also be linked to emotional aspects, peer problems at school, family problems or depression. There is no drug that is officially approved for migraines in children. The medication that has been studied most closely is ibuprofen. A controlled trial of 7.5 mg/kg showed a response of 76 %. Acetaminophen with a dose of 15 mg/kg was studied in patients aged 4 to 16 years. The response was 54%. Neither of those two medications showed any adverse side effect. Sumatriptan nasal spray was well tolerated, showed a 1 hour response of 58%, had no side effects, but a bitter aftertaste. It was also pointed out that in a study oral sumatriptan and placebo scored the same. It is obviously most important to get to the root of the problem and eliminate the triggering factors after which medication can be used. The general consensus is to treat the attacks rapidly and consistently, get the patient back to his or her daily functioning, minimize backup medications and make sure that there are minimal or no adverse side effects.
