The problem
•   5% -10% side effects with statin
•   More patients become statin eligible
•   The use of high dosage
•   Combination therapy
•   Special situations: Pregnancy-Elderly-Children
•   Run in phases may underestimate the
    problem
Higher doses= More adverse effects
                 “TNT”
Non CV mortality with the high doses need further evaluation

Elevated liver enzymes:1.2% vs 0.2% p<0.001

Rhabdomyolysis 2 cases(80mg) vs 3 cases(10mg)

5461 pts. were excluded in the run in phase

          Liver enzyme elevation and myalgia (%)              Presented at AHA 2005
Elevated Liver Enzymes: What to do?
• Less than 1%
• Usually asymptomatic
• Rarely cause Liver failure
• Reversible
• Usually improve with continuing statin or
  reducing the dose
• Change to another statin is an option
Muscle Symptoms
• Myalgia is the most common (1.5-3.5%)

• Myopathy: Less common (0.05%)

• Rhabdomyolysis: Serious ( 1/10000)
Co-Q 10
• May reduce statin induced muscle symptoms

• No large well controlled studies

• Minimal side effects
-
Populations at risk
•   Elderly > 75-80
•   Small body mass index
•   Hepatic or renal dysfunction
•   Concomitant medications
•   Large amount of Grapefruit
•   Combination lipid lowering therapy
Steps to Minimize the Risk of Muscle Toxicity with Fibrate–Statin
                         Combination Therapy

   Use statin alone for non-HDL-C goals
   Use fish oils or niacin rather than fibrates
   Keep the doses of the statin and fibrate low
   Dose the fibrate in the AM and the statin in the PM
   Avoid in renal impairment
   Discontinue therapy if muscle symptoms are present and
    CK is >10 times the upper limit of normal

If not tolerated what to do?
• DC Statin temporarily to be sure that the Side
  effects are statin related
• Re-challenge with a lower dose or change to
  other statin
• If multiple statins are not tolerated we can use
  less effective
  drugs(Resin, Ezetimibe, Niacin, Fibrate)
• More intense Life style change program

• 32 yrs female
•  30 weeks twin pregnancy
• IUF
• +ve FH (CABG for the Father @ 45yrs)
• Father T Cholesterol known to be more than
  300 mg/dl
• Border line Bl. G.
• No Ho DM or hypertension

• 1st set : T.Ch: 320mg/dl, TGs: 580onmg/dl

• The day of exam: T ch: 310mg/dl ,TGs: 640
  mg/dl
Plan
• No statin during pregnancy and lactation
• Fibrates are tumerogenic for the fetous
                  WHAT TO DO?
• Omega III : safe but no LDL lowering effect
• Glucose-Insulin infusion
• Immunoadsorpton session??
New Statin Intolerance Clinic:
               Work up
• Validated questionnaire including FH of statin
  intolerance
• Level of CK and Vit. D
• Renal and thyroid function tests
• Genetic testing for statin efficacy and
  potential toxicity
• Proximal muscle strength evaluation
• Percutaneous muscle biopsy

Conclusions
• Statin intolerance is not common however the
  numbers are increasing as Millions are
  receiving statin
• Side effects with a statin do not mean that
  other statin couldn’t be used
• Elderly, Low BMI, hepatic or renal
  dysfunction, high dosage and combinations
  are important predictors
Immunoadsorption- LDL aphaeresis (to take away
[Greek])
Indications:
*failure medical (>LDL>200 mg/dl with CAD)
and > 300 mg/dl without CAD


*Coast s 3000 / tt every 2 weeks for life
Statin in childhood for familial dyslipidemia

• The earlier to start the better (CIMT)

• As early as 8 years is effective and probably
  safe
Apo A-1 Milano
• Five weekly infusions of an ApoA-I Milano/ phospholipid
  complex produced significant regression of coronary
  atheroma burden by IVUS.

• Adverse events were similar to placebo.

• Coronary disease is more dynamic than previously
  realized and can be rapidly affected by agents that
  augment reverse cholesterol transport.

With LDL 300, TG 520mg/dl start with
1.   Fenofibrate
2.   statin
3.   Statin + Fibrate
4.   Statin+ Ezetemib
When liver enzymes increase to 1.5
              times base line
1.   Continue with the same dose
2.   Change to another statin
3.   Reduce the dose
4.   Replace with fibrate
All are contraindications to statin
               therapy except
1.   Pregnancy
2.   Lactation
3.   Liver cirhosis
4.   Active hepatitis
All are RF for statin muscle toxicity
                    except
•   Age below 40 yrs
•   Renal impairment
•   Liver dysfunction
•   Combination therapy
All can improve statin intolerance
                  except
•   Adding Co Q10
•   Giving fibrate @AM and Statin @PM
•   Using 2c9 metabolized statin
•   Using Cyp3A4 metabolized statin
