 Mean
deficient transferrin
Corpuscular Volume

Lab Markers 1 (GGT)

Gamma-glutamyltransferase





↑ With heavy drinking
↑ In: heart disease, kidney disease, preg
GGT >35
-Heavy drinking
-↑ Before liver damage
-Sensitivity for heavy drinking ~75%
GGT >50 may indicate liver damage
Normalizes ~5 weeks of abstinence
© AMSP 2012
14
Lab Markers 2 (LFT)

Liver enzymes: AST and ALT
 ALT in liver, AST in many tissues
 ↑ In high use AND liver damage
 Absolute value &ratio important
-AST (14-38 U/L normal range)
-ALT (15-48 U/L normal range)
-AST:ALT ratio >2 suggestive of alcohol
 Less sensitive than GGT
© AMSP 2012
15
Lab Markers 3 (CDT)

Carbohydrate deficient transferrin
 Transferrin=protein; transports iron
 Abnormal form produced in ↑ drinking
 CDT >20 g/l indicates heavy drinking
 Few other conditions ↑
 Sensitivity & specificity ~75% (=GGT)
 Normalizes ~1 month of abstinence

16
Lab Markers 4 (MCV)
 Mean

Corpuscular Volume
Size of red cells (nl =80-100u)
↑
By heavy drinking
 >90u
suggests heavy drinking
 MCV

Screening/Evaluation

 R/O
→ distress/↓ functioning
general medical or mental dx
 Delirium
Tremens (DT’s) (rare)

Delirium Tremens (DT’s)

Seen in ~5% AUD

Disorientation (confusion)

Fluctuating consciousness

Hyperactivity/excitation

↑ Pulse, bp, temp, etc.

 Can
be fatal if med problems
 Onset
↑
48-96 hours after last drink
Risk prior episodes/med probs
 R/O
other causes

23
Withdrawal Tx
 Benzodiazepines
(e.g. diazepam [Valium])
Correct transmitter problems
Day 1: give enough to ↓ symptoms
↓ Dose ~20% day 1 dose each day
↑ Dose if symp ↑; ↓ dose next day
 Anticonvulsants
not needed

24
Clinical Case
 80
y/o female
 ↑BP, 3 days s/p hip surgery
 Keeps trying to get out of bed
 Confused
 Agitated
 ↑ BP and bilateral hand tremor
 Dx: EtOH withdrawal delirium (DT)

criteria for DT’s
 Symptom
onset at 72 hours
 Confusion
 Psychomotor
↑

26
Clinical Case
 Rx
recommendations:
1:1
observation
Folate
 R/O
1mg/d, thiamine 100mg/d
other causes
 Benzodiazepine
© AMSP 2012
27
Benzodiazepine Rx


Chlordiazepoxide (Librium);diazepam (Valium)

Longer half-life=smoother withdrawal

Better seizure protection

But can over-sedate elderly and liver impaired
Lorazepam (Ativan)=better choice in this pt

Shorter half-life = ↓ risk of oversedation

↓ Risk if liver prob; not metabolized in liver

28
Wernicke Encephalopathy
 Cause:
↓ thiamine (Vit B1)
 Emergency:
untreated →20% death
 Triad:
Confusion, ataxia (incoordination),
ophthalmoplegia (eye muscle paralysis)
 Rx:
IV thiamine (to optimize absorption)

29
Korsakoff’s Syndrome

Impaired memory in alert, responsive pt

Limited insight to memory loss

Confabulation -- makes up stories

Retrograde & anterograde memory loss

Psychiatric Disorders: MDE
 Co-morbid
major depression

Gen pop major depressive episode (MDE) ~15%

AUD slightly ↑ even when not drinking

MDE unrelated to drinking
-Alcohol ↑ depressive symptoms
-Alcohol intoxication/withdrawal ↑ suicidal ideation
© AMSP 2012
31
Psychiatric Disorders: AID
 Alcohol
induced: severe intoxication →
temporary MDE in ~30%
 Causal
relationship--psychiatric disorder
not predating AUD
 Treatment
= abstinence (≠ meds)
 Depression
↓↓ in 2 d to 4 wks abstinence
© AMSP 2012
32
Psychiatric Disorders: Psychosis
 Psychosis – Hallucinations
 Delirium
(e.g. post surgery, DT’s) --usually
disappear as delirium resolves
 ~3%
AUD during severe intoxication
-No delirium
-Alcohol-induced psychosis
-Disappears 2 d to 4 wks without meds
-Antipsychotics (e.g. risperidone) control symp

 Action
not a problem
– considers change
- makes plans
- changes behavior

- sustains change

 Support ability to change if desired
 Result: pt takes initiative
 Stage : contemplation→preparation
