Infertility and PCOS

Background
Polycystic ovarian syndrome, the single most common endocrinopathy amongst women of
reproductive age, is an ancient genetic disorder. Descriptions over the last 2000 years
describe a combination of symptoms and signs including menstrual irregularity, masculine
habitus, sub-fertility and possible obesity. The ancestral genes encoding for PCOS are likely
to have selected during the Paleolithic hunter-gatherer era over 10,000 years ago.
Transmission through the generations is likely to be through children conceived between
fertile carrier males and sub fertile affected females; the reduced fecundity of affected
women being offset by their improved energy utilisation and a reduction in the risk of
maternal mortality.

Definition
Rotterdam (2003) Consensus:

2 out of the following 3, excluding other aetiologies:
    Oligo- or anovulation
    Clinical or biochemical signs of hyperandrogenism
    Polycystic ovarian morphology

Prevalence:
6 – 10% of women. Similar across different populations across the globe

Reproductive consequences of PCOS
Insulin resistance is the key leading to compensatory hyper-insulinaemia is the key
endocrine disturbance leading to abnormal ovarian androgen production, abnormal
folliculogenesis and gonadotrophin production. These effects are amplified by obesity
Anovulation:

First line treatment remains clomiphene citrate.
Second line: Ovarian diathermy or gonadotrophins
Third line      IVF – risk of OHSS

Role of Metformin

      ↑Ovulation rate (OR = 2.1)
      ↑ Pregnancy rate BUT
      Does NOT translate to an increase in the livebirth arte

      No effect on BMI
      Decreases fasting insulin but only in non-obese (BMI< 30)
      No effect on lipid profile

Obesity

Worsens all biochemical and clinical features of PCOS

      Evidence base exists for diet and exercise (5 % reduction in BMI leads to significant
       improvement in biochemical parameters)
      Newer parmacotherapies eg Orlistat and Bariatric Surgery may be of benefit to some
       women

Heart failure management in the community

Epidemiology
The prevalence of heart failure in primary care is uncertain but is often quoted as about 1%.
However, about 3% of adults in the UK are taking loop diuretics and have a similar
prognosis to patients with heart failure. The prevalence of patients at high risk or with
symptoms that could be attributed to heart failure probably exceeds 5%.

Most patients who develop cardiovascular disease will develop heart failure before they die.
Annual mortality for well-managed patients with heart failure in primary care is about 5-10%.
Most new diagnoses of heart failure occur as a result of an acute event precipitating
hospital admission. Little effort has been made to detect pre-symptomatic major cardiac
dysfunction.

Hospital episode statistics for the UK show that about 5% (>250,000 per year) of all
emergency hospital admissions are recorded as due to or complicated by heart failure.
Careful audit suggest that this may only be ~25% of the total disease burden. About 50% of
patients are aged <75 years most of whom have a reduced LVEF (see glossary). Hospital
mortality is about 5% and about 20% of the survivors will die within the following year,
despite widespread use of guideline-indicated therapy. Older patients are more likely to
have a preserved LVEF (HFpEF – see glossary). Their hospitality mortality is about 15% and
about 30% will die within the following year.

These statistics indicate a general failure of the UK and other health systems to address the
problem of heart failure adequately. Most health care costs are due to staff costs.
Technologies and treatments that improve the delivery of care are likely to be effective and
cost-efficient.

Glossary

LVEF = left ventricular ejection fraction a traditional measure (not very accurate) measure of
left ventricular contractile performance. It is stroke volume (the volume of blood ejected by
the ventricle in a heart beat) divided by the volume of blood in the left ventricle at the end of
diastole. Please note that blood may be going backwards (mitral regurgitation) as well as
forwards. A normal LVEF is >50%.

LVSD = left ventricular systolic dysfunction – a term that is used to indicated that the LVEF
is reduced – usually to below 40%, but see below………

HFnEF or HFpEF = heart failure with normal or preserved ejection fraction. Used to be
considered largely due to diastolic LF dysfunction (a stiff ventricle). However many of these
patients have long-axis systolic dysfunction (so LVSD with a normal LVEF), valve disease,
pulmonary hypertension and right ventricular disease. A real hotch-potch. Much better
diagnosed with a blood test (BNP/NT-proBNP) than by an echocardiogram.

BNP/NT-proBNP – these are B-type natriuretic peptides (the active component and the
inactive fragment (proBNP) of the pro-hormone – cardiac stress hormones that are the most
powerful medium to long-term prognostic markers available in patients with cardiovascular
disease. Pretty good at diagnosing cardiovascular disease too.

MRA – mineralocorticoid receptor antagonists (spironolactone for women and eplerenone
for men)

Detection & Investigation

Early detection of cardiac dysfunction has been made much more effective in primary care
with development of natriuretic peptides. An elevated plasma concentration always
indicates a serious medical condition (although not necessarily cardiac) and a normal level
excludes serious cardiac or renal disease. The NICE guidelines on the use of natriuretic
peptides are overly complex and should be simplified. In case of suspected thyroid
dysfunction measure thyroid hormone. In case of suspected cardiac dysfunction measure a
natriuretic peptide. It will be elevated in conditions other than left ventricular systolic
dysfunction such as atrial fibrillation and renal dysfunction but tends to be somewhat lower
in the morbidly obese.

Patients with an NT-proBNP <200ng/L can be reassured and alternative diagnoses sought.
NT-proBNP 200-400ng/L indicates some cardiac stress but unlikely to cause symptoms or
require specific therapy. It is a call to tighten up on blood pressure and lipid control. Patients
with values >400ng/L should be investigated (standard haematology and biochemistry
should usually be sent at same time as BNP/NT-proBNP) including an ECG and an
echocardiogram. If the LVEF is normal, the patients is in sinus rhythm and eGFR is
>40mls/minute then the patient either has right sided disease or LV diastolic dysfunction
(HFpEF).


Treatment

The treatment of HFpEF is based on management of comorbidity such as AF (digoxin, beta-
blocker and anti-coagulant) or hypertension (ACEi/ARB/MRA/MRA/beta-blocker) and fluid
retention.

Patients with moderate or severe valve disease should be evaluated for repair or
replacement.

Patients with LVSD should be considered for triple therapy with ACE inhibitor (or ARB),
beta-blocker and MRA.
Titrate dose of ACEi or ARB to target unless limited by hypotension or renal dysfunction.
Titrate beta-blockers to target doses unless limited by bradycardia or hypotension. Aim for a
resting heart rate of 50-60bpm. Patients who reach target doses, are in sinus rhythm and
still have a resting heart rate >70bpm should receive ivabradine – a sinus node inhibitor. It
has few side effects and may be an alternative to beta-blockers when contra-indicated or
not tolerated.
MRA should be titrated to achieve serum potassium of 4.2 & 5.2mmol/L (4.5 is ideal).
Diuretics are used to control fluid retention.
Digoxin and anti-coagulants are reserved for patients with atrial fibrillation.

For patients with severe persistent LVSD should be considered for an implantable
defibrillator if preventing sudden death is considered a risk worth avoiding. Patients who
have moderate or severe symptoms and a QRS duration >120msec and are in sinus rhythm
should be considered for atrio-bi-ventricular pacing (cardiac resynchronisation therapy or
CRT).

Patients with severe symptoms or recent hospitalisation should be considered for home
telemonitoring.

Recent trials targeting coronary disease in patients with heart failure have been
disappointing. Rosuvastatin failed to improve prognosis in two large trials. Two trials of
revascularisation failed to demonstrate an important impact on prognosis. Finally, two
randomised trials have shown that aspirin is associated with a substantial increase in
hospitalisation for heart failure. Whether clopidogrel is a better anti-platelet agent in patients
with heart failure is currently being tested in the CACHE (Clopidogrel versus Aspirin in
Chronic HEart failure) trial; funded by the NHS HTA and enrolling patients from primary &
secondary care. It’s a simple, pragmatic, open-label, low-hassle study. If you are interested

Palliative care for non-malignant conditions

Palliative care services in the UK have grown up alongside oncology services, often based in
the voluntary sector and funded by cancer charities. This has led to an inequity of services
and generic support provided for people with non-malignant conditions. Publications over
the past 10 – 15 years, however, have highlighted the symptom burden experienced by
patients with other life shortening illnesses, and their carers.

Despite this, many services across the UK have been slow to systematically respond to this.
There is also a relative dearth of research to help provide an evidence base in symptom
control or service provision for supportive and palliative care non-malignant disease.

This presentation will:
     present some barriers and solutions in providing supportive and palliative care for
       patients with non-malignant conditions
     give an overview of the evidence base for the management of breathlessness as an
       exemplar symptom in non-malignant disease
     summarise the main features of advance care planning for end of life care
