Leukopenia-a rare complication secondary to invasive liver abscess syndrome in a patient with diabetes mellitus:A case report

BACKGROUND Thrombocytopenia is a common complication of invasive liver abscess syndrome(ILAS)by Klebsiella pneumoniae(K.pneumoniae)infection,which indicates severe infection and a poor prognosis.However,the presence of leukopenia is rare.There are rare reports on leukopenia and its clinical significance for ILAS,and there is currently no recognized treatment plan.Early and broad-spectrum antimi-crobial therapy may be an effective therapy for treating ILAS and improving its prognosis.CASE SUMMARY A 55-year-old male patient who developed fever,chills,and abdominal distension without an obvious cause presented to the hospital for treatment.Laboratory tests revealed thrombocytopenia,leukopenia,and multiple organ dysfunction.Imaging examinations revealed an abscess in the right lobe of the liver and thromboph-lebitis,and K.pneumoniae was detected in the blood cultures.Since the patient was diabetic and had multi-system involvement,he was diagnosed with ILAS accom-panied by leukopenia and thrombocytopenia.After antibiotic treatment and sys-temic supportive therapy,the symptoms disappeared,and the patient’s condition almost completely resolved.CONCLUSION Leukopenia is a rare complication of ILAS,which serves as an indicator of adverse prognostic outcomes and the severity of infection.

Nucleoside diphosphate-linked moiety X-type motif 15 R139C genotypes impact 6-thioguanine nucleotide cut-off levels to predict thiopurine-induced leukopenia in Crohn’s disease patients

BACKGROUND Thiopurine-induced leukopenia(TIL)is a life-threatening toxicity and occurs with a high frequency in the Asian population.Although nucleoside diphosphate-linked moiety X-type motif 15(NUDT15)variants significantly improve the predictive sensitivity of TIL,more than 50%of cases of this toxicity cannot be predicted by this mutation.The potential use of the 6-thioguanine nucleotide(6TGN)level to predict TIL has been explored,but no decisive conclusion has been reached.Can we increase the predictive sensitivity based on 6TGN by subgrouping patients according to their NUDT15 R139C genotypes?AIM To determine the 6TGN cut-off levels after dividing patients into subgroups according to their NUDT15 R139C genotypes.METHODS Patients’clinical and epidemiological characteristics were collected from medical records from July 2014 to February 2017.NUDT15 R139C,thiopurine S methyltransferase,and 6TGN concentrations were measured.RESULTS A total of 411 Crohn’s disease patients were included.TIL was observed in 72 individuals with a median 6TGN level of 323.4 pmol/8×10^8 red blood cells(RBC),which was not different from that of patients without TIL(P=0.071).Then,we compared the 6TGN levels based on NUDT15 R139C.For CC(n=342)and CT(n=65)genotypes,the median 6TGN level in patients with TIL was significantly higher than that in patients without(474.8 vs 306.0 pmol/8×10^8 RBC,P=9.4×10-^5;291.7 vs 217.6 pmol/8×10^8 RBC,P=0.039,respectively).The four TT carriers developed TIL,with a median 6TGN concentration of 135.8 pmol/8×10^8 RBC.The 6TGN cut-off levels were 411.5 and 319.2 pmol/8×108 RBC for the CC and CT groups,respectively.CONCLUSION The predictive sensitivity of TIL based on 6TGN is dramatically increased after subgrouping according to NUDT15 R139C genotypes.Applying 6TGN cut-off levels to adjust thiopurine therapies based on NUDT15 is strongly recommended.

Prognostic value of chemotherapy-induced leukopenia in small-cell lung cancer

Objective: Chemotherapy is the standard treatment for small-cell lung cancer (SCLC), and leukopenia is a common side effect. This study assesses whether chemotherapy-induced leukopenia is a predictor of efficacy and whether it is associated with the survival of SCLC patients. Methods: A retrospective analysis was conducted on data from 445 patients with SCLC who received standard chemotherapy for 4 to 10 cycles. The World Health Organization grading system classifies leukopenia during chemotherapy as follows: absent (grade 0), mild (grades 1 and 2), or severe (grades 3 and 4). The primary endpoint is overall survival (OS). Results: The association between chemotherapy-induced leukopenia and OS was assessed. According to a multivariate Cox model with time-varying covariates, the hazard ratio of death was significantly lower among patients with mild leukopenia than among patients with severe leukopenia at 0.687 (0.506 to 0.943) and 1.414 (1.147 to 1.744), respectively. The median survival was 13 months (95% CI: 11 to 15 months) for patients who did not experience leukopenia, 17 months (95% CI: 14 to 18 months) for those with mild leukopenia, and 14 months (95% CI: 13 to 16 months) for those with severe leukopenia (absent vs. mild vs. severe leukopenia, P=0.047). Conclusion: Leukopenia during chemotherapy is associated with the survival of SCLC patients. Mild leukopenia is strongly associated with longer survival time.

Analysis of the Therapeutic Effect of Sodium Copper Chlorophyllin Tablet in Treating60Cases of Leukopenia

Objective： To evaluate the efficacy and safety of sodium copper chlorophyllin （trademarked as ＂Yebaike Tablet （叶拜克） which is abbreviated as YBK in treating leukopenia. Methods： One hundred and five patients with leukopenia caused by various factors were randomized into 3 groups. The 60 patients in the YBK group took orally YBK Tablets at the dose of 40 mg, three times per day, the 30 patients in the leucogen group were treated with Leucogen Tablets （利血生片） at the dose of 20 mg, three times per day, and the 15 patients in the placebo group were administered with vitamin C tablets 100 mg, three times per day. All the subjects were treated for 1 month. The change of peripheral leucocytes count after treatment and adverse drug reaction that occurred in patients were studied. Results： In the 60 patients treated with YBK, the treatment proved to be markedly effective in 34 cases, effective in 17 and ineffective in 9, the total effective rate being 85%, which was significantly higher than that in the placebo group （26.7%, P〈0.01） and similar to that in the leucogen group （83.3 %, P〉0.05）. No adverse reaction was found in the treatment course. Conclusion： YBK can be used in the treatment of leukopenia caused by various factors, satisfactory in efficacy and safe in use.

Incidence of leukopenia after intraperitoneal vs combined intravenous/intraperitoneal chemotherapy in pseudomyxoma peritonei

AIM: To investigate the clinical impact of post-hyperthermic intraperitoneal chemotherapy(HIPEC) leukopenia, intraperitoneal and combined intravenous/intraperitoneal drug administrations were compared.METHODS: Two patient cohorts were retrospectively analyzed regarding the incidence of postoperative leukopenia. The first cohort(n = 32) received Mitomycin C(MMC)-based HIPEC intraperitoneally(35 mg/m2 for 90 min) and the second cohort(n = 10) received a bidirectional therapy consisting of oxaliplatin(OX)(300 mg/m2 for 30 min) intraperitoneally and 5-fluorouracil(5-FU) 400 mg/m2 plus folinic acid 20 mg/m2 intravenously. The following data were collected retrospectively: Age, sex, length of operation, length of hospital stay, amount of resection including extent of peritonectomy, peritoneal cancer index, CC(completeness of cytoreduction)-status and leukocyte-count before cytoreductive surgery(CRS) and HIPEC, on days 3, 7 and 14 after CRS and HIPEC. HIPEC leukopenia was defined as < 4000 cells/m3. RESULTS: Leukopenia occurred statistically more often in the MMC than in the OX/5-FU-group(10/32 vs 0/10; P = 0.042). Leukopenia set-on was on day 7 after CRS and MMC-HIPEC and lasted for two to three days. Three patients(33%) required medical treatment. Patients affected by leukopenia were predominantly female(7/10 patients) and older than 50 years(8/10 patients). Thelength of hospital stay tended to be higher in the MMCgroup without reaching statistical significance(22.5± 11 vs 16.5 ± 3.5 d). Length of operation(08:54 ± 01:44 vs 09:48 ± 02:28 h) were comparable between patients with and without postoperative leukopenia. Prior history of systemic chemotherapy did not trigger postHIPEC leukopenia. Occurrence of leucopenia did not trigger surgical site infections, intraabdominal abscess formations, hospital-acquired pneumonia or anastomotic insufficiencies. CONCLUSION: Surgeons must be aware that there is a higher incidence of postoperative leukopenia in MMCbased HIPEC protocols primarily affecting females and older patients.

Hematological abnormalities in liver cirrhosis

Hematological abnormalities are common in cirrhosis and are associated with various pathophysiological mechanisms.Studies have documented a prevalence of thrombocytopenia,leukopenia,and anemia in patients with compensated cirrhosis of 77.9%,23.5%,and 21.1%,respectively.These abnormalities carry significant clinical implications,including considerations for invasive procedures,infection risk,bleeding risk,and prognosis.Previously,cirrhosis was believed to predispose patients to bleeding due to alterations observed in classical coagula-tion tests such as prothrombin time,partial thromboplastin time,international normalized ratio,and thrombocytopenia.However,this understanding has evol-ved,and cirrhosis patients are now also acknowledged as being at a high risk for thrombotic events.Hemostasis in cirrhosis patients presents a complex pheno-type,with procoagulant and anticoagulant abnormalities offsetting each other.This multifactorial phenomenon is inadequately reflected by routine laboratory tests.Thrombotic complications are more prevalent in decompensated cirrhosis and may correlate with disease severity.Bleeding is primarily associated with portal hypertension,endothelial dysfunction,mechanical vessel injury,dissem-inated intravascular coagulation,endotoxemia,and renal injury.This review comprehensively outlines hematologic index abnormalities,mechanisms of hemostasis,coagulation,and fibrinolysis abnormalities,limitations of laboratory testing,and clinical manifestations of bleeding and thrombosis in patients with liver cirrhosis.

白细胞减少的准广泛耐药肺结核患者使用康替唑胺的临床实践分析

目的:分析1例白细胞减少的准广泛耐药(pre-extensively drug-resistant,pre-XDR)肺结核患者使用康替唑胺的临床实践过程,为类似耐药结核病患者探索有效的抗结核治疗方案提供参考。方法与结果:患者4个月前被确诊为pre-XDR肺结核,并予贝达喹啉+利奈唑胺+氯法齐明+环丝氨酸+丙硫异烟胺抗结核治疗;治疗20 d后,反复出现头晕、多梦、易醒等症状;1 d前,再次出现难以入睡症状并伴烦热感和右膝关节疼痛,遂入院治疗;住院期间,患者多次出现白细胞减少情况,考虑为利奈唑胺骨髓抑制所致,服用利可君片亦不能改善,临床在斟酌后决定停用利奈唑胺,改用康替唑胺,之后白细胞水平果然明显恢复;此外,患者反复出现的难以入睡症状考虑为环丝氨酸的中枢神经毒性反应,而住院期间出现的Q-T间期延长则考虑是贝达喹啉所致,遂决定停用此二药;最后,患者的抗结核方案被调整为康替唑胺+氯法齐明+阿米卡星+乙胺丁醇+丙硫异烟胺,之后患者未再出现不适症状和指标异常。结论:pre-XDR肺结核属于较为难治的疾病,治疗时用药较多且复杂,很容易发生药物不良反应,并且部分药物不良反应可能会导致严重不良后果;对此,临床应采取积极干预措施,并及时调整抗结核治疗方案,以保证患者的用药安全和治疗效果。
