Hematologic problems in psychosomatic medicine psychiatric clinic of north america DR. Yasser Alhathial team Presented by: Ali bahathig Introduction: The consultation psychiatric is frequently called assess patients in medical settings primary or secondary hematologic disorders. This article adresses psychiatric issues → specific to patients who have selected hematologic disorders, including: → B12 → folate dificency → sikle cell disease → Hemophilia Finally, a review of hematologic side effects of psychotropic medication is also included. B12 & FOLATE DEFICIENCY: B12 & folate deficincy have similar consequences: → Nervous system → Megaloblastic anemia Both are cofactors for conversion: Homocysteine → Methionine Deficiency of both corrolate with: ↑ Homocysteine level → C.V.S, STROKE, DEMENTIA & ALzheimer’s disease ↑ Homocysteine level & ↓ of B12 & folate: also associared with depression. Vitamin B12 Necessary coenzyme & cofactor in virous reaction: → synthesis of DNA + methionine Epidemiologic studies: → prevalence of about 20% in general population → number of geriatric individuals → even higher → common in psychiatric populations. Pernicious anemia → B12 deficiency → Autoimmune disorder → associated with other autoimmune disorder: → thyroiditis, DM, grave’s disease……. Dietary B12 deficiency is rare Food or oral-cobalamin malabsorption may caused by: H. pylori infection Intestinal overgrowth → antibiotics chronic use of metformin, antacids, H-2 blocker, PPI, alcoholism and gastric surgery Vitamin B12 Malabsorption results from: → Gastrectomy → Ileal diseases → Bowel resection → Crohn’s disease Clinical Manifestation: Hematologic manifestation: megaloblastic anemia macrocytosis with hypersegmented polymorphonuclear leuckocytes thrombocytopenia leukopenia and pancytopenia Gastrointestinal manifestation: intestinal metaplasia Hunter’s glossitis Diarrhea and jaundice. Neuropschiatric manifestation: → common in B12 deficiency → in the elderly → may precede hematologic signs → symmetrical peripheral neuropathy → paresthesias & numbness → subacute combined degeneration (SCD) → less common → posterior & lateral column disruption → loss of vibration & position sense → ataxia, weaknees & spasticity rare manifestation: optic neuritis or atrophy & incontinence Psychiatric manifestation: → mood changes → psychosis → cognitive impairment → obsessive – compulsive disorder B12 deficiency is a common cause of → potentially reversible dementia & confusion Diagnosis and treatment: Low normal serum B12 + megaloblastic anemia or typical neuropsychiatric findings → further investigation Low normal level between 150ng ⁄L to 200ng ⁄ L Intrinstic factor Ab, serum gastrin: → Pernicious anemia Treatment recommendation: 1000 microgram IM of hydroxycobalamin or cyanocobalamin daily for 1 ⁄ 52 then maintenence dose 1 ⁄ 12 or Q 3 ⁄ 52 Oral replacement also is effective Remission is typically achived in weeks But, continued maintenance therpy is recommended → replete body stores → maintain longer period of remmsion Significant improvement of neuropsychiatric function has been shown after B12 adminstration. Degree of recovery → symptom severity Adminstration of folate only to correct macrocytic anemia (unrecognized B12 deficiency ) → will reverse the hematologic abnormalities → but neurologic impairment may continue → leading to irreversible deficits Folic acid: Folate is important in mood & cognition, brain growth, differentiation, development & repair. These mechanisms: → nucleotide synthesis → DNA transcription & integrity Folate may protect agnist: → certain cancers → heart disease → birth defects → dementia Presumably via the lowering homocysteine Folate deficiency: → inadequate diet, alcoholism, chronic illness → drugs ( phenytoin, valproic acid, lamotrigine barbiturates, oral contraceptive ) → malabsorption More common in the elderly More prevalent in psychiatric inpatients compared with patients without psychiatric illness (controlling for drug & alcohol abuse) One third of psychiatric patients, especially with depression Clinical manifestations: Symptoms of folate deficiency are similar of B12 SCD is specific to B12 deficiency Depression is more common in folate deficiency Insufficient folate during conception & eraly pregnancy results: neural tube defects (NTD) Folate deficiency is invariably accompanied by: ↑ Plasma homocysteine level ↑ Risk CVS disease, Dementia Depression Diagnosis & treatment: Low RBC folate + ↑ plasma homocysteine → is good standard for the diagnosis more accurate than measuring serum folate alone No clear guidelines for the dose or duration → folate therapy for nervous system disorder Treatment is recommended for at least 6 months To ↓ risk of NTDs: 0.4 mg daily is recommended for woman at high risk: 4-5 mg dialy is recommended → one month at least prior to conception → through at least first trimester of pregnancy In depressed patients: → low folate levels → higher levels of depression → less likely to respond to antidepressants Coppen showed that supplementation of: fluoxetine + folic acid → improved antidepressant response → concurrent ↓ in plasma homocysteine level → not necessarily to ↑ plasma folate level Sickle cell disease (SCD): SCD is the most common hemoglobinopathy The vaso-occulsive crisis is the hallmark of SCD → acute episodes of severe pain → extreme of temperature, infectious illness, → dehydration and physical exertion may → precipitate crises but, majority of crises → without an identifiable cause Vaso-occulsive produce: → acute pain → in short term → end-organ damage → in long term ( bone, kidney, lungs, eyes & brain) Many patients suffer from chronic pain as result of avascular necrosis or leg ulcer The neuropsychiatric manifestation of SCD can be grouped in three main categories: → 1- depression and anxiety → 2- problems with substance abuse & dependence → 3- central nervous system damage These issues are further complicated by the poor psychosocial circumstances Depression and anxiety: Prevalence of depression is about 26% Anxiety disorders have been reported to be 7.1% Children with SCD have ↑ prevalence: excessive fatigue, physical complaints & impaired self-esteem These feeling arise: → frequent hospitalization → absences from school → inability to experience a normal childhood Adults with SCD face: → physical deformities + stigma of addiction → the consequences of facing these stigma: self-deprivation, self-hate, suspiciousness, depression and anxiety Physical deformities: → delayed growth → chronic hemolysis & vaso-occlusion → problem with self-esteem → dissatisfaction with body image → social isolation → participation in athletic is limited Chronic & acute pain: Patients experiences 0.8% episodes per year. However, 1% of patient experiences more than 6 episodes per year. Nature of pain, which has been reported to be as severe as childbirth In last 15 years, opioid treatment has been used widely for SCD pain → control pain → improve function capacity → decrease hospitalization Substance dependence & addiction behaviors difficult to define in any chronic pain condition Few studies that address addiction in SCD report a low prevalence Despite this lack of evidence in medical literature medical practitioners often overestimate addiction Studies demonstrate: → 63% of nurse believe addiction is prevalent → 53% of ER physicians → 23% of hematologist though more than 20% Fear of iatrogenic addiction, → physicians may under treat pain As a result of under treatment, patient may develop a pseudo-addcition (addiction like behavior occur → inadequate pain) May seek illegal narcotics to manage their pain → long-term problems with true addiction Some patients may inappropriately use opioid in non pain symptoms: → insomnia → depression → anxiety In recent studies, 31.4% of adult SCD were found to abuse alcohol Central nervous system damage: Brain disease from SCD complication begins early in life → neurocognitive dysfunction 25-33% of children with SCD have CNS effects Seizures occur in 12-14% of SCD patients → often lead to stroke CVA occur in 10-15% of SCD children These demonstrate: → intellectual deficits (ranging from borderline to moderate MR) → reduced language function → problem with adjustment Cognitive deficits in SCD children can lead to: → educational problems → Intellectual impairment → verbal problems → problems with attention and concentration → dementia later in life Hemophilia: Hemophilia is a bleeding disorder → deficiency of the coagulation factors Hemophilia A (factor VIII) Hemophilia B (factor IX) → well known inherited bleeding disorders → clinically, indistinguishable from one another X-linked & mainly affects males Classification: severe moderate mild Useful for predicting bleeding tendency and prognosis Severe hemophilia ( < 1% clotting factor) bleed spontaneously into: → joints → muscles → soft tissues → body cavities Neonatal periods: →1-4% risk of developing intracranial hemorrhage Most children are asymptomatic → until they start crawling → bruise easily and bleed following minor injuries (family of these children → child abuse) By age of 4 years most children experience → bleed into a joint Adult experience recurrent bleed into: → large joints & muscles → joint bleeding →severe acute pain Repeated bleed lead to destruction: → cartilage → bone → muscle wasting → chronic pain Moderate hemophilia (1-5% clotting factor): → typically diagnosed by the age of 5 years → bleeding episodes occur less frequently Mild hemophilia (> than 5% clotting factor) → diagnosed later following trauma, tooth extraction or surgery → spontaneous bleeding is rare In 1990s, more than 80% of severe hemophilia patients were infected with viral illnesses → HIV, hepatitis B & C In children & adolescents higher rate of anxiety disorder have been reported in hemophilic than asthmatics Physician are reluctant to prescribe opiates → despite the severe pain Individual, group and family psychotherapy → useful psychotherapeutic Caution is needed in prescribing psychotropic → dose of antidepressant, antipsychotic & opiate → reduced to compensate for hepatic impairment → may ↑ the risk of bleeding Hemophilia & AIDS patients face many stressors: → opportunistic infection → physical wasting, declining health, chronic pain → CNS complications……. Mother of HIV +ve hemophilic more distressed than mother of HIV –ve hempphilic After death from AIDS, bereaved families: → extensive psychologic counseling & support Study in Japan found → 7-9 years after death bereaved family members → deep sorrow & grief → regret, anger, guilt 70% of bereaved family → restricting daily activities 50% of bereaved family → mental heath problems Hematologic side effects & drug interaction of psychotropic agents: Antipsychotic: → aripiprazole & ziprasidone → do not have → hematologic side effects Agranulocytosis is rare → most common & serious Low potency > high potency Clozapine causes agrnulocytosis → 0.8 % → highest risk in → first 6 months → ↓ significantly → case fatality rate → 4.2-16% (growth stimulating factor GSF) → Weekly WBC count is necessary If WBC count < 2000/mm or absolute neutrophil count < 1000/mm → immediate cessation of clozapine Stopping clozapine → recovery in WBC in 3 weeks Mortality risk associated with agranulocytosis → ↑ if infection occur while still on the drug As Clozapine cause bone marrow suppression: → GSFs → normal bone marrow production Potential hematologic side effects: → aplastic anemia, neutropenia, eosinophilia → thrombocytopenia Antidepressants: SSRIs inhibit platelet function → bruising & bleeding → especially → with aspirin or NSAIDs SSRIs: ↑ CNS serotonin ↓ platelets serotonin → ↓ platelets aggregation Upper GIT bleeding may occur at a frequency from 1 in100 to 1 in 1000 patient-year exposure to highaffinity drugs with SSRIs → elderly Caution is advised in patient at high risk of GI bleeding → consider prescribing a antidepressant Patients taking SSRIs should generally use → smaller doses or avoid aspirin or NSAIDs Risk of GI bleeding → highest among patients on both SSRIs & NSAIDs While the evidence to date → SSRIs do not cause intracranial bleeding → there is a report that patients taking → SSRIs along with statins → higher risk for subarachnoid hemorrhage While some reviews have concluded there is → no ↑ risk of combining SSRIs with warfarin → case reports of bleeding with concomitant use of SSRIs & warfarin Fluoxetine is the most commonly offending agents. Interactions between warfarin & SSRIs → potentially serious consequences → enhanced or reduced anticoagulant activity The possible mechanisms → cytochrome p450 Fluoxetine, fluvoxamine, paroxetine → highest potential → interaction Citalopram, nefazodone, sertraline → relatively less likely to interact with warfarin Agrnulocytosis due to TCAs is a rare Idiosyncratic condition → bone marrow toxicity Lower frequency than antipsychotic Agrnulocytosis has been associated: → imipramine → clomipramine → desipramine Clomipramine-induced agranulocytosis → recombinant granulocyte colony-stimulating factor Benzodiazepines: Agrnulocytosis has rarely been reported No causal relationship has been established No relationship between daily dose or total cumulative dose & occurrence of hematologic side effects Lithium: Lithium stimulate leukocytosis with true proliferative response In patients on lithium therapy: documented increases in the: → number of platelet → platelet serotonin & histamine levels Lithium-induced hematologic side effects → manage hematologic toxicities associated with other agent & disorder Patients with persistent leucopenia &thrombocytopenia following chemotherapy or radiotherapy → can be treated with lithium Anticonvulsants & mood stabilizers: Carbamazepine should be avoided → history of bone marrow depression → Produce a transient reduction in WBCs →10% of patients during first 4 months Very rarely it causes potentially: → fatal agranulocytosis → aplastic anemia Baseline CBC count → advised before starting If the WBCs count drop below 3500/mm → carbamazepine should be stopped Carbamazepine stimulate it’s own metabolism → after being taken for a period of time → suddenly decrease Induce hepatic metabolism → reduces the anticoagulant effect of warfarin → Carbamazepine level & INR will need to be monitored frequently Neutropenia, thrombocytopenia & macrocytic anemia → have been associated with valproate Lamotrigine may also cause agrnulocytosis All anticonvulsants should be discontinued when the WBCs count drop below 3000/mm Think you
