How COPD patients can sing their way to better health this Christmas

Carol Singers (CC BY 2.0)

Singing carols is a big part of Christmas cheer, but not many people realise that singing can also be helpful for people with lung disease. COPD is an extremely common condition – there are 1.3 million people with this diagnosis in the UK. Existing treatments help to some extent, but do not reverse the underlying pathology, meaning that even with optimal care many patients remain breathless with activity limitation and poor quality of life. This symptom burden represents a major area of unmet need. Singing for Lung Health (SLH) groups are a potential way for patients to gain skills to improve control of their breathing and posture, reducing symptom burden and enhancing wellbeing.

What is singing for lung health?

Singing for lung health involves taking part in classes led by a specially trained singing teacher. Patients learn techniques to help control their breathing and posture as part of a group activity which is fun and sociable. The goal for the groups is to get better at singing, an artistic objective. By doing this individuals gain skills that help them to cope with their lung condition, a health improvement objective. The classes have a particular focus on activities and exercises that are helpful for people with lung disease and so differ from more generic “singing for well-being” groups.

Singing for lung health has grown from a few small clinical trials to more than 80 groups nationally. As well as the plausibility of an approach based on learning to control the breath in people with lung disease, singing is also a fun social activity. Results from the Royal College of Physicians COPD audit show that provision of pulmonary rehabilitation is still limited, so there is a need for activities to sustain the physical and social benefits that these produce once people have completed them. For some people, taking part in a singing group may be a useful stepping stone to agreeing to join a formal rehabilitation program. (more…)

Lung volume reduction – new hopes and missed opportunities in COPD

COPD, chronic obstructive pulmonary disease, has traditionally been thought of as an irreversible and somewhat hopeless condition. Many patients with COPD may be missing out on the possibility for a dramatic improvement in their condition. They deserve better.

COPD, is a common and important condition. There are 1.3 million people with a diagnosis of COPD in the UK and it’s now the third leading cause of death worldwide. The main symptoms are breathlessness, cough and sputum production.

The term COPD encompasses a range of pathological processes, usually caused by smoking or inhaling other noxious materials. It includes chronic bronchitis – inflammation and damage to airways as well as emphysema – destruction of the lung tissue itself and damage to the blood vessels in the lung. In emphysema the walls of the alveoli (air sacs) break down. The lung tissue loses its elasticity and becomes baggy, and air gets trapped in the lungs making breathing uncomfortable. In some people the condition is caused by alpha one antitrypsin (A1AT) deficiency; the inherited lack of a defensive enzyme, which makes their lungs much more vulnerable.

There are treatments including inhaled medication, pulmonary rehabilitation and flu vaccination, and for people who continue to smoke, smoking cessation is the most effective. Despite the best standard care the condition is progressive and conventional treatments cannot so far reverse the underlying process. (more…)

TB or not TB? Why tuberculosis remains one of the top 10 causes of death today


I was always a sickly child – when I was eleven years old, doctors injected my forearm with tuberculin in order to check whether my immune system raised a response to the bits and bobs of dead tuberculosis (TB) bacteria in it. If it did, it meant my immune system had already been prodded into battling TB, that is, it had previously encountered or was currently encountering an infection with TB bacteria. The injection site swelled like a furious bee sting, the doctors decided TB was the root cause of all my troubles, and I was intensely medicated for the next six months. My symptoms improved, and I have since evolved (visibly even!) towards the hale and hearty end of the healthiness spectrum.

In retrospect, now that I am medically trained and pursuing a PhD in TB immunology, I can appreciate all that my care team must have had to consider before starting an eleven-year-old child on a rigorous anti-TB treatment based on an educated guess. My symptoms were not typical of classical lung TB, the most common and infectious form of TB, they were mostly gastrointestinal, but then TB has also been known to stitch the gut into uncomfortable knots. My mother had recently been diagnosed with a cold abscess, due to TB of the bone, and though this could not possibly be infectious (based on centuries of observation) it still raised flags as it meant I had a history of contact with a TB patient. I showed an immune response to the tuberculin skin test (TST), but then I had received the BCG vaccine, which is a close relative of TB bacteria. This meant I could elicit a cross-reactive immune response and result in a positive TST even in the absence of TB infection due to the similarity of the two bacteria. (more…)

Smoke and the burnout of muscles

Smoking is a leading cause of preventable death and disease in the world. It is estimated that the society costs associated with smoking are approximately ₤12.9 billion a year, including the NHS cost of treating smoking related diseases and loss of productivity.

Chronic obstructive pulmonary disease (COPD) is one of the major diseases caused by smoking. The disease ranks third among the leading causes of death worldwide. Around 1.2 million Britons suffer from the disease (Source: British Lung Foundation). The usual clinical picture is that of a smoker with symptoms that include shortness of breath and chronic cough. The muscle lab team at the Royal Brompton Hospital’s BRU, led by Professor Michael Polkey and Dr Nicholas Hopkinson is looking at different ways to improve COPD care, and at the different mechanisms by which interventions improve patient outcomes in the disease.

Wide-ranging consequences

In recent years, it has been discovered that the negative consequences of the pulmonary disease are not just limited to within the rib cage. The wider effects of the disease on multiple body systems has a large and solid evidence base to support it. More than half of COPD patients suffer simultaneously from at least two other conditions known to often occur alongside the disease (so-called ‘comorbid’ conditions); the presence of which is commonly used as an indication of disease severity (1). The disease burden usually takes its toll on the patients’ quality of life, daily physical activities and social interactions. (more…)
