Introduction

TheJehovah’sWitnessreligiousmovementisaChristiansect with over 2.6 million followersworldwide that forbids the transfusionofbloodandbloodcomponentstoitsmembers.1

There is limited experience in the treatment of Jehovah’s Witnesseswithacutemyeloidleukemia(AML).Treatmentof patients,whodonotacceptrequiredbloodsupporton reli-giousgrounds,isalwaysadifficultproblem.Thisdilemmais ofparticularconcernincasessuchasacuteleukemiainwhich thephysicianhimself,bychoosingandapplyingappropriate treatment,mayincreasetheneedfortransfusionsupport.2

The standard treatment for AML is seven days of an anthracyclineand threedaysofcytarabine (7+3);withthis regimen70–80%ofyoungadultsand40–60%ofolderadults, willachievecompleteremission.3Thecombinationof

cytara-bine plus an anthracycline results in severe pancytopenia andthereforerequirestransfusionsupport.4Duringinduction

Thepatientandfamilywereinformedthattheappropriate treatment(7+3) implied markedand prolonged myelosup-pression requiring transfusion support, and the patient refusedtograntconsentfortransfusions.Aminimally myelo-suppressivetreatmentplanconsistingonlyofvinblastinefor cytoreductionwasthenproposedandaccepted.Thepatient was fully aware of the reduced probability of achieving a durablecompleteremission.

She was hospitalized at diagnosis and 10mg of vin-blastinewas administered forcytoreduction. Thenext day the WBCcount was 17.4×109/L. Four days later, the WBC

was4.5×109/L,Hb was7.7g/dLand theplateletcountwas

Discussion

There isonly onereportofsuccessful remissioninduction using standardchemotherapy(7+3)inaJehovah’sWitness with AML.8 In another report, a 20-year-old woman was

diagnosed with AML by morphology in 1979, but without molecular,cytogeneticsorflowcytometryconfirmatory stud-ies.Shewastreatedwithvincristine,prednisoneandAra-C and was cured atthe time ofthe report.9 On the grounds

of having only a morphology diagnosis and the patient respondedtothatspecifictreatment,wehypothesizethatthis casemayhavebeenalymphoblasticleukemia.Thereareother casereports onpatients survivinglongerthan our patient, howeverallweretreatedinaninpatientsetting,and/orhad infectiouscomplications.10

Weacknowledgethatazacitidineisatherapeuticoptionfor patientswithmyelodysplasticsyndromesandolderpatients withAML.11ItsuseinaJehovah’sWitnesshasbeenreported,

howeverbecauseofitselevatedcostsitwasnotavalidoption forthispatient.

HereinwereportourexperiencetreatingaJehovah’s Wit-ness using vinblastine, low dose Ara-C and valproic acid but without blood transfusions, based on a treatment for elderly patients published byCorsetti et al.6 who reported

anoverallresponserateof35%andanoverallmedian sur-vivalofeightmonths(range: 2–36).These authorsincluded histonedeacetylaseinhibitors,suchasvalproicacid,which haveaprovenefficienttoovercomedifferentiationarrestof AML blasts.12 We decided to use this regimen because of

itsresponserates.LowdoseAra-Chasbeenusedinseveral regimens ofphaseIItrialsforAMLforseveralyearsgiving responsesthatincludecompleteresponse.13Thistherapyis

Vinblastine is a drug rarely used in the treatment of AML.Vincaalkaloids,suchasvinblastine,targetmicrotubule dynamicsbybindingtotubulinmonomersanddimers.14They
