NUTRITIONAL DEFICIENCY & ALCOHOL USE DISORDERS Ann M. Manzardo, Ph.D. Department of Psychiatry & Behavioral Sciences Kansas University Medical Center Kansas City, Kansas © AMSP
Nutritional Deficiencies • Once common, now rare in west • Availability of food ↑ • Nationalized fortification of foods • Began in US, early 1900’s • Iodine added to salt (goiters) • Expanded to other nutrients, 1940’s © AMSP
Nationalized Fortification • Dairy products • Calcium/vitamin D to milk (rickets) • Vitamin A to margarine (night blindness) • Grain products • Replaced B vitamins lost in milling • Niacin, thiamine, riboflavin • Folate added 1998 © AMSP
Who is at Risk Today? • High risk groups in western countries • Elderly • Medical conditions (vomiting/GI) • Certain psychiatric conditions → Alcohol Use Disorders (AUDs) © AMSP
Lecture Focus: Nutrition & AUDs • Definitions • AUDs & nutrition • Thiamine • Other B vitamins • How to help © AMSP
Abuse vs.Dependence Dependence ( ≥3) • Tolerance • Withdrawal • Not sticking to limits • Unable to cut down • ↑ time with ETOH • ↓ time elsewhere • Use in spite of problems Abuse ( ≥1) • Role failure • Risk of harm • Run-ins with law • Relationship trouble Repeats 12 months © AMSP
What is a Micronutrient? • Needed in small amounts (<100 mcg/day) • “Essential” for bodily functions • Diet may be only source • 2 kinds • Vitamins – organic compounds • Minerals – “trace” elements, ions or salts © AMSP
B-Complex Vitamins Meats: poultry, eggs, fish & liver Beans & grains; Brewer’s yeast • Thiamine (B1) • Riboflavin (B2) • Niacin (B3) • Pantothenic acid (B5) • Pyridoxine (B6) • Biotin (B7) • Folate (B9) • Cobalamin (B12) © AMSP
Lecture Focus: Nutrition & AUDs • Definitions • AUDs & nutrition • Thiamine • Other B vitamins • How to help © AMSP
AUDs → Nutritional Deficiency • Lifestyle factors • Poor dietary habits • ↓ Access to food (poverty, homelessness) • Alcohol preferred to food © AMSP
AUDs → Nutritional Deficiency • Gastric Problems • Alcohol damage • Gastric mucosa inflamed • Barrier to absorption • ↓ absorption of nutrients © AMSP
AUDs → Nutritional Deficiency cont’d • Selective loss of B vitamins • B vitamins water (not fat) soluble • Low cellular stores • Levels ↓ quickly • ↑ daily intake needed • → Thiamine Deficiency (B1) © AMSP
Lecture Focus: Nutrition & AUDs • Definitions • AUDs & nutrition • Thiamine (B1) • Other B vitamins • How to help © AMSP
Thiamine Function Oxidative Metabolism Thiamine (B1) Glycolysis Kreb Cycle Generates ATP for energy Anaerobic Metabolism ↑ lactic acid ↑ cell damage/death © AMSP
Thiamine Function cont’d Pentose Phosphate Shunt DNA RNA Glucose-6-P Ribose-5-P Transketolase Thiamine (B1) Transaldolase ↓ Cell Growth © AMSP
Consequences of Thiamine Deficiency • Tissue-selective damage • Heart muscles/neurons • ↑ energy demand • ↓ energy stores • 2 clinical syndromes (wet/dry beriberi) © AMSP
Wet Beriberi • Cardiovascular • Irregular heartbeat • Heart failure • Edema (fluid retention) © AMSP
Dry Beriberi • Neurological • Pain/numbness in limbs (neuropathy) • Balance/coordination problems • Emotional disturbances © AMSP
Neurological Syndromes • Rare but serious • 2 main syndromes • Wernicke’s encephalopathy • Korsakoff’s syndrome © AMSP
Wernicke’s Encephalopathy • Sudden onset of symptoms • Impaired eye movement • Can’t look to side • Jerky movement • Staggering gait (ataxia) • Reversible with treatment Opthalmoplegia of left eye Nystagmus © AMSP
Korsakoff ‘s Syndrome • Memory loss (amnesia) • ↓ Formation (anterograde) • ↓ Recall (retrograde) • Confabulation • False memories/beliefs • “Storytelling” • Lack of insight © AMSP
Genetic Vulnerability • Sub-population identified • ~10% of Non AUD • ~ 30% of Wernicke-KorsakoffSyndrome • Abnormal transketolase enzyme • ↓ affinity for thiamine (B1) • ↑ levels needed to activate • ↑ alcohol-related problems © AMSP
Lecture Focus: Nutrition & AUDs • Definitions • AUDs & nutrition • Thiamine (B1) • Other B vitamins • How to help © AMSP
Other B vitamin deficiencies • Folate (B9), >40% • Pyridoxine (B6), up to 50% • Riboflavin (B2), ~17% • Overlapping effects on: • DNA, RNA, red blood cell (RBC) synthesis • Sugar metabolism • Cell growth/energy production © AMSP
Folate (B9) Deficiency • Anemia, 2 types • Abnormally large RBCs, megaloblastic • Ruptured RBCs, hemolytic • ↓ appetite • Weakness, fatigue • Hair loss © AMSP
Pyridoxine (B6) Deficiency • Similar to niacin (B3) deficiency • Failure to process iron to heme • Anemia, sideroblastic • ↓ healthy RBCs • ↑ abnormal RBC (sideroblasts) © AMSP
Pyridoxine (B6) Deficiency • Skin inflammation • Dermatitis • Lips/mouth, cheilosis • Neuropathy in hands/feet • Neurological problems • Seizures © AMSP
Riboflavin (B2) Deficiency • Inflamed skin/mucous membranes • Mouth ulcers • Cheilosis • Eyes • Bloodshot, itchy/watery • ↑ sensitivity to light © AMSP
Riboflavin (B2) Deficiency cont’d • SeborrheicDermatitis • Scaly, oily rash • Near glands • Face/upper lip • Genitals (scrotum, vulva) • Permanent scarring possible © AMSP
Lecture Focus: Nutrition & AUDs • Definitions • AUDs & nutrition • Thiamine (B1) • Other B vitamins • How to help © AMSP
Treatment of Nutritional Deficiency • Supplement guidelines • Full B-complex, 7-14 days • Oral, daily treatment • Add minerals, help vitamins work • Prenatal vitamins often used • Inexpensive/easy © AMSP
