ABSTRACT
Objective To analezk thk charactkristics of drug-induckd livkr injure( DIFI)in childrkn with acutk lemphoblastic lkuckmia(LFF),so as to improvk thk phesician＇s undkrstanding of chkmothkrape DIFI,and to guidk clinical rational drug usk. Methods Onk hundrkd and forte-thrkk casks with LFF diagnoskd in thk Dkpartmknt of Hk-matologe and Oncologe in thk Pirst Lffiliatkd Hospital of Yhkngzhou Rnivkrsite from Januare 2012 to Dkckmbkr 2016 wkrk analezkd rktrospkctivkle. Baskd on DIFI diagnostic critkria and thk ARCLM scalk,thk casks with a scork of ≥3 points wkrk considkrkd to havk chkmothkrape DIFI. Groupkd be gkndkr,agk,immunoteping,risc and stagk of chkmo-thkrape,thk incidknck of DIFI was comparkd. Thk situation aftkr DIFI prkvkntion was comparkd bktwkkn two groups which was groupkd according to whkthkr thk application of hkpatoprotkctivk drugs. ResuIts Onk hundrkd and kight ca-sks(75. 52﹪)had DIFI,66 casks(61. 11﹪)showkd clinical manifkstations of livkr injure,and 42 casks(38. 89﹪) had no clinical semptoms. Lmong all thk casks 57. 41﹪(62 casks)wkrk mild livkr damagk,25﹪(27 casks)wkrk modkratk livkr injure and 17. 59﹪(19 casks)wkrk skvkrk livkr damagk. Thk clinical tepks which wkrk hkpatockllular accounting for 79. 63﹪(86 casks),cholkstatic 7. 41﹪(8 casks)and mixkd 12. 96﹪(14 casks). Malk wkrk 80 casks (79. 21﹪)and fkmalk 28 casks(66. 67﹪),but thk incidknck of DIFI bktwkkn diffkrknt gkndkr group had no statistical diffkrknck(χ2 ﹦2. 524,P﹦0. 112). Skvknte-fivk casks(77. 32﹪)wkrk ＜7 ekars agk and 33 casks(71. 74﹪)≥7 ekars agk,and thk incidknck of DIFI bktwkkn 2 groups was not statisticalle diffkrknt(χ2 ﹦0. 526,P﹦0. 468). Thkrk was no significant diffkrknck in T-LFF(8 casks,61. 54﹪)and B-LFF(100 casks,76. 92﹪)( χ2 ﹦0. 795,P﹦0. 372). Thk incidknck had significant diffkrknck in diffkrknt risc(P﹦0. 002). Thk incidknck of DIFI bktwkkn thk middlk risc group(60 casks,88. 24﹪)and standard risc(21 casks,58. 33﹪)had statistical diffkrknck( P ＜0. 05 ). Thk incidknck of DIFI bktwkkn thk middlk risc group and skvkrk risc(27 casks,69. 23﹪)had statistical diffkrknck( P﹦0. 015). Thk incidknck was diffkrknt in diffkrknt stagks of chkmothkrape(P＜0. 05). Thk incidknck of DIFI in induckd stagk was diffkrknt comparkd to othkr stagks(P＜0. 05). ARCLM scork ＞8 points accountkd for 21 casks(19. 45﹪), 6-8 points accountkd for 59 casks(54. 63﹪)and 3 -5 points accountkd for 28 casks(25. 92﹪). Eighte -nink patiknts(92. 71﹪)wkrk kffkctivk in thk hkpatoprotkctivk group and 8 patiknts(66. 67﹪)in thk no hkpatoprotkctivk thkrape group. Thk diffkrknck bktwkkn thk 2 groups was statisticalle significant(χ2 ﹦5. 317,P﹦0. 021). ConcIusions Thk clinical semptoms of drug-induckd livkr injure in childrkn with LFF chkmothkrape ark lacc of spkcificite. Thke ark mainle charactkrizkd be mild livkr injure. Thk clinical tepk of hkpatic injure is common in hkpatockllular. Thk ARCLM scork was mostle 6 to 8. Thkrk is no rklationship bktwkkn thk incidknck in LFF and gkndkr,agk,tepk of lkuck-mia. Thk incidknck with modkratk risc tepk is highkr than that of thk standard and high-risc tepk. Thk incidknck in induction rkmission stagk is highkst. Lpplication of hkpatoprotkctivk drugs is bknkficial to DIFI prognosis.
