Clinical Pharmacology:

pul23) and dna polymerase (pol; pul30) genes. frameshifts were commonly isolated and result in premature truncation of the hsv tk product with consequent decreased susceptibility to acyclovir. mutations in the viral tk gene may lead to complete loss of tk activity (tk negative), reduced levels of tk activity (tk partial), or alteration in the ability of viral tk to phosphorylate the drug without an equivalent loss in the ability to phosphorylate thymidine (tk altered). in cell culture the following resistance-associated substitutions in tk of hsv-1 and hsv-2 were observed (table 1). table 1: summary of acyclovir (acv) resistance-associated amino acid substitutions in cell culture hsv-1 tk p5a, h7q, l50v, g56v, g59a, g61a, k62n, t63a, e83k, p84s, d116n, p131s, r163h, a167v, p173l, q185r, r216s, r220h, t245m, r281stop, t287m, m322k hsv-2 tk l69p, c172r, t288m hsv-1 pol d368a, y557s, e597d, v621s, l702h, n815s, v817m, g841c hsv-2 pol - in hsv-infected patients clinical hsv-1 and hsv-2 isolates obtained from patients who failed treatment for their α-herpesvirus infections were evaluated for genotypic changes in the tk and pol genes and for phenotypic resistance to acyclovir (table 2). hsv isolates with frameshift mutations and resistance-associated substitutions in tk and pol were identified. the listing of substitutions in hsv tk and pol leading to decreased susceptibility to acyclovir is not all inclusive and additional changes will likely be identified in hsv variants isolated from patients who fail acyclovir-containing regimens. the possibility of viral resistance to acyclovir should be considered in patients who fail to respond or experience recurrent viral shedding during therapy. table 2: summary of acv resistance-associated amino acid substitutions observed in treated patients hsv-1 tk g6c, r32h, r41h, r51w, y53c/d/h, y53stop, d55n, g56d/s, p57h, h58/n/r/y, g59r, g61a, k62n, t63i, q67stop, s74stop, y80n, e83k, p84l, y87h, w88r, r89q/w, e95stop, t103p, q104h, q104stop, h105p, d116n, m121l/r, s123r, q125h, m128l, g129d, i143v, a156v, d162a/h/n, r163g/h, l170p, y172c, p173l, a174p, a175v, r176q/w, r176stop, l178r, s181n, v187m, a189v, v192a, g200c/d/s, t201p, v204g, a207p, l208f/h, r216c/h, r220c/h, r221h, r222c/h, l227f, t245m/p, l249p, q250stop, c251g, r256w, e257k, q261r, t287m, l288stop, l291p/r, l297s, l315s, l327r, c336y, q342stop, t354p, l364p, a365t hsv-2 tk r34c, g39e, r51w, y53n, g59p, g61w, s66p, a72s, d78n, p85s, a94v, n100h, i101s, q105p, t131p, d137stop, f140l, l158p, s169p, r177w, s182n, m183i, v192m, g201d, r217h, r221c/h, q222stop, r223h, y239stop, r271v, p272s, d273r, t287m, c337y hsv-1 pol k532t, q570r, l583v, a605v, a657t, d672n, v715g, a719t/v, s724n, f733c, e771q, s775n, l778m, e798k, v813m, n815s, g841s, i890m, g901v, v958l h1228d hsv-2 pol e250q, d307n, k533e, a606v, c625r, r628c, e678g, a724v, s725g, s729n, i731f, q732r, m789k/t, v818a, n820s, y823c, q829r, t843a, m910t, d912n/v, a915v, f923l, t934a, r964h note: additional substitutions to acyclovir resistance may exist. cross-resistance cross-resistance has been observed among hsv isolates carrying frameshift mutations and resistance-associated substitutions, which confer reduced susceptibility to penciclovir (pcv), famciclovir (fcv), and foscarnet (fos) [table 3]. table 3: summary of amino acid substitutions conferring cross-resistance to pcv, fcv or fos cross-resistant to pcv/fcv hsv-1 tk g6c, r32h, r51w, y53c/h, h58n, g61a, s74stop, e83k, p84l, t103p, q104stop, d116n, m121r, i143v, r163h, l170p, y172c, a174p, r176q/w, q185r, a189v, g200d, l208h, r216c, r220h, r222c/h, t245m, q250stop, r256w, r281stop, t287m, l315s, m322k, c336y cross-resistant to pcv/fcv hsv-1 pol a657t, d672n, v715g, a719v, s724n, e798k, n815s, g841s cross-resistant to pcv/fcv hsv-2 tk g39e, r51w, y53n, r177w, r221h, t288m cross-resistant to pcv/fcv hsv-2 pol k533e, a606v, c625r, r628c, s729n, q732r, m789k/t, v818a, n820s, f923l, t934a cross-resistant to fos hsv-1 pol d368a, a605v, d672n, l702h, v715g, a719t/v, s724n, l778m, e798k, v813m, n815s, v817m, g841c/s, i890m cross-resistant to fos hsv-2 pol k533e, a606v, c625r, r628c, a724v, s725g, s729n, i731f, q732r, m789k/t, v818a, y823c, d912v, f923l, t934a, r964h
