Can Your Heartburn Drugs Cost Your Life?

Millions of people around the globe are taking heartburn and indigestion medications known as proton pump inhibitors (PPIs). These drugs neutralize the acid in the stomach and are widely prescribed by the physicians, with low doses available even without prescription.

However, Ziyad Al-Aly, an epidemiologist from the University of Washington and co-author of a study said, “We saw a small excess risk of dying that could be attributed to the PPI drug, and the risk increased the longer anyone takes them. The risk is also higher in those who take the drug unnecessarily.”

The team of researchers followed 350,000 American participants of different age and sex for five years and compared those taking PPIs with those taking another acid suppressant like H2 blocker. The individual condition of the participant like high blood pressure or HIV was also taken into account.

The results revealed a 25% higher risk of death in those who took PPIs than those who took H2 blocker; 15% higher risk than those not taking PPIs and 23% higher risk than those not taking any acid suppressant.

Gareth Corbett, a gastroenterologist from Addenbrooke’s hospital in Cambridge cautioned against the panic created by this study, as he believes in the effectiveness of PPIs in controlling bleeding in gastric ulcers.

However, Corbett and the researchers agreed on the use of PPIs only when necessary and advised patients to stop using them when not required, after consulting the physician.

Immunotherapy In Type 1 Diabetes

A Landmark Trial Establishes The Safety Of Immunotherapy In Type 1 Diabetes

Nearly 5% of the population in the  United States suffers from type 1 diabetes; an autoimmune disorder where the body’s immune system specifically fails to recognize pancreas’ insulin producing beta cells and mistakenly attacks them.

In the absence of sure shot treatment and the dearth of studies on immunotherapy, Dr Mohammad Alhadj Ali, Cardiff University School of Medicine, U.K., and Mark Peakman, professor of clinical immunology at King’s College London, conducted a study on the possible benefits of immunotherapy in type 1 diabetes.

Dr Ali and his team examined the effect of the immunotherapy molecule, proinsulin peptide, in 27 diabetic people within a period of 100 days. The participants were divided into two groups – one receiving the shots of immunotherapy and the other receiving placebo for 6 months at 2 or 4 weeks interval. Their markers of insulin, C-peptide levels were tested at 3, 6, 9, and 12 months, and compared with baseline levels.

In the end, the placebo group revealed a significant decline in their C-peptide levels and about 50% increase in insulin intake over a period of 12 months. On the other hand, the group that received immunotherapy shots had stable C-peptide levels and insulin intake.

This led Prof. Peakman to conclude, “Though the sample size for research was small, it has encouraged the researchers to conduct a larger study in future. Moreover, immunotherapy has been found safe for people with type 1 diabetes and may be acceptable in children as well as in long periods of treatment.”

High-Fat Diet and Colorectal Cancer

Long Awaited Link Between High-Fat Diet and Colorectal Cancer Found

Colorectal cancer, the cancer that originates in the colon or rectum, is the third most common cancer diagnosed in the United States. A plethora of studies have established a link between consumption of high-fat diet and increased risk of colorectal cancer, but the mechanism of this association was till now obscure.

As reported in the journal, Stem Cell Reports, researchers from the Cleveland Clinic in Ohio have unfolded this mechanism. In a study that utilized mice as the models, researchers have been able to identify a pathway that drives the growth of cancer stem cells in their colon in response to a high-fat diet.

Feeding the mice with high-fat diet increased the growth of cancer stem cells in their colon. Furthermore, researchers identified a cellular signalling pathway, JAK2-STAT3 that drives the growth of cancer stem cells in the colon in response to a high-fat diet. Blocking this pathway reversed the growth of cancer stem cells in colon triggered by consuming a high-fat diet.

The study was co-authored by Dr Matthew Kalady, co-director of the Comprehensive Colorectal Cancer Program at the Cleveland Clinic. “This study is first of its kind that mediates a link between high-fat diet and colorectal cancer through the demonstration of a cellular pathway; a discovery that opens the gates to new ways of treating colorectal cancer”, says Dr Kalady.

Another co-author, Justin D. Lathia further appreciates it as an insight into the influence of diet on cancer stem cells in advanced cancers.
