1.1!Overview+
Hepatitis" C" virus" (HCV)" infection" remains" a" major" coEmorbidity" in"
hemodialysis"patients.1E3"The"incidence"and"prevalence"rates"of"HCV"infection"
in" hemodialysis" patients" are" much" higher" than" those" in" the" general"
population," and" are" attributed" to" high" rates" of" nosocomial" HCV"
transmission.4E6"With"regard"to"HCV"genotype"distribution,"HCV"genotype"1"
(GTE1)" infection" is" the" most" prevalent" type" of" infection" worldwide" and" the"
genotype"distribution"in"HCVEinfected"individuals"receiving"hemodialysis"(HD)"
is" similar" to" that" observed" in" HCVEinfected" individuals" with" normal" renal"
function.7E9"
Compared"
to"
nonEHCV"
infected"
hemodialysis"
patients,"
HCVEinfected" patients" have" increased" risks" of" liverErelated" morbidity" and"
mortality.10" Although" HCVEinfected" hemodialysis" patients" who" receive" renal"
transplantation" have" survival" advantages" over" those" who" remain" on"
maintenance"dialysis,"these"patients"still"have"poor"patient"and"graft"survival,"
as" well" as" have" poor" responses" to" interferon" (IFN)Ebased" therapy.11E13" In"
contrast,"hemodialysis"patients"who"eradicate"HCV"infection"have"improved"
biochemical," virologic" and" histologic" responses," whether" on" maintenance"
dialysis"or"after"renal"transplantation.14,15"
+
1.2!Clinical+experience+of+IFNIbased+Therapy+
Approximately"one"third"of"hemodialysis"patients"with"chronic"HCV"infection"
achieve" sustained" virological" response" (SVR)" by" conventional" IFN" or"
peginterferon" monotherapy.16E18" In" addition" 18E30%" of" patients" receiving"
IFNEbased"monotherapy"prematurely"discontinued"treatment"due"to"adverse"
events"(AEs)."Although"the"addition"of"ribavirin"to"IFN"further"improves"the"
SVR" rate" in" HCVEinfected" patients" with" normal" renal" function," ribavirin" has"
been"considered"contraindicated"to"treat"HCVEinfected"hemodialysis"patients"
because" of" concern" for" lifeEthreatening" hemolytic" anemia." Recently," pilot"
studies" have" indicated" the" feasibility" of" adding" lowEdose" ribavirin" (200" mg"
three" times" per" week" to" daily" 400" mg," adjusted" to" achieve" a" target"
concentration" of" 10E15" μmol/L)," to" IFN" for" treatment" of" HCVEinfected"
hemodialysis" patients.19E28" Generally," the" SVR" rate" and" the" premature"

19"
"
discontinuation"rate"due"to"nullEresponse,"severe"anemia,"and/or"heart"failure"
for" combination" therapy" are" 56%" and" 22%," respectively.29" Based" on" these"
smallEscale"studies,"lowEdose"ribavirin"(daily"200"mg)"was"approved"in"August"
2011" by" the" U.S." Food" and" Drug" Administration" to" treat" HCVEinfected"
hemodialysis" patients.30" Two" recent" wellEconducted" randomized" control"
studies" to" compare" the" efficacy" and" safety" of" combination" therapy" with"
peginterferon" alfaE2a" (135" μg/week)" plus" lowEdose" ribavirin" (RBV)" (200"
mg/day)" or" monotherapy" with" peginterferon" (135" μg/week)" for" 48" and" 24"
weeks" in" treatmentEnaïve" HCV" GTE1" and" GTE2" infected" individuals" receiving"
hemodialysis"showed"that"the"SVR"rates"of"combination"therapy"groups"were"
greater"than"those"of"monotherapy"groups"(64%"versus"34%,"p"<"0.001"for"
HCV" GTE1;" 74%" versus" 44%," p" <" 0.001" for" HCV" GTE2)," respectively.31,32"
Although" the" SVR" rate" of" combination" therapy" with" peginterferon" plus"
lowEdose"ribavirin"is"higher"than"that"of"peginterferon"monotherapy."About"
70E75%" of" these" patients" experienced" clinically" significant" anemia" which"
needed" high" dose" of" erythropoiesis" stimulating" agents" (ESAs)" to" keep" the"
hemoglobin" level" within" the" safety" range." Although" telaprevir" (TVR)Ebased"
triple"therapy"has"been"used"to"treat"4"HCVE1"patients"receiving"hemodialysis"
who"were"not"responsive"to"prior"peginterferon"plus"RBV"with"good"efficacy,"
the"added"onEtreatment"adverse"events"(AEs)"and"the"pill"burden"precluded"
the"widespread"use"of"this"agent.33,34"

The"recent"introduction"of"IFNEfree"direct"acting"antiviral"agents"(DAAs)"has"

patients"receiving"PrOD"with/without"RBV"for"12"weeks.37"The"SVR12"rate"of"
PrOD"without"RBV"was"similar"to"that"of"PrOD"with"RBV"in"HCV"GTE1b"patients"
(99.0%" versus" 99.5%)." However," the" SVR12" rate" in" HCV" GTE1a" patients"
receiving" PrOD" with" RBV" was" marginally" higher" than" those" receiving" PrOD"
without" RBV" (97.0%" versus" 90.2%).38" The" PEARLEII" study" further" confirmed"
that" in" treatmentEexperienced" nonEcirrhotic" HCV" GTE1b" patients," treatment"

and" treatmentEexperienced" compensated" cirrhotic" HCV" GTE1b" patients.40"
With" regard" to" safety," PrOD" with/without" RBV" showed" excellent" safety"

Although" peginterferon" monotherapy" and" combination" therapy" with"

many"studies,"the"efficacy"for"the"treatment"regimens"were"only"modest"(SVR"
rate"about"60%)."In"addition,"the"onEtreatment"AEs"and"SAEs"by"IFNEbased"
therapies" were" frequently" encountered" in" HCVEinfected" patients" receiving"
hemodialysis." Of" note" was" the" pronounced" onEtreatment" hemoglobin" level"
decrease" in" patients" receiving" combination" therapy" by" peginterferon" plus"
lowEdose" RBV," necessitating" significant" RBV" dose" reduction" and" highEdose"
erythrocyte"stimulating"agent"(ESA)"support."
By"receiving"IFNEfree"DAA"therapies,"HCVEinfected"patients"have"excellent"SVR"
rates,"low"onEtreatment"SAE"and"AE"rates,"shorter"treatment"duration,"and"
low" pill" burdens." The" PK" study" of" ombitasvir," paritaprevir," ritonavir" and"
dasabuvir"proves"the"excellent"safety"profiles"and"dose"adjustment"are"not"
needed" for" PrOD" regimen" in" subjects" with" various" degrees" of" renal"

onEtreatment" and" offEtherapy" antiviral" effects" in" HCV" GTE1a" and" GTE1b"
infected"patients"receiving"PrOD"plus"lowEdose"RBV"and"PrOD,"respectively."
