Application of immunosuppressants in patients with autosomal dominant polycystic kidney disease after kidney transplantation / 南方医科大学学报

OBJECTIVE@#To investigate the optimal dose range of immunosuppressants in patients with autosomal dominant polycystic kidney disease (ADPKD) after renal transplantation.@*METHODS@#A cohort of 68 patients with ADPKD who received their first renal transplantation between March, 2000 and January, 2018 in our institute were retrospectively analyzed, with 68 non-ADPKD renal transplant recipients matched for gender, age and date of transplant as the control group. We analyzed the differences in patient and renal survival rates, postoperative complications and concentrations of immunosuppressive agents between the two groups at different time points within 1 year after kidney transplantation. The concentrations of the immunosuppressants were also compared between the ADPKD patients with urinary tract infections (UTI) and those without UTI after the transplantation.@*RESULTS@#The recipients with ADPKD and the control recipients showed no significantly difference in the overall 1-, 5-, and 10- year patient survival rates (96.6% 96.0%, 94.1% 93.9%, and 90.6% 93.9%, respectively; > 0.05), 1-, 5-, and 10-year graft survival rates (95.2% 96.0%, 90.8% 87.2%, and 79.0% 82.3%, respectively; > 0.05), or the incidences of other post- transplant complications including acute rejection, gastrointestinal symptoms, cardiovascular events, pneumonia, and neoplasms ( > 0.05). The plasma concentrations of both tacrolimus and mycophenolate mofetil (MPA) in ADPKD group were significantly lower than those in the control group at 9 months after operation ( < 0.05). The incidence of UTI was significantly higher in ADPKD patients than in the control group ( < 0.05). In patients with ADPKD, those with UTI after transplantation had a significantly higher MPA plasma concentration ( < 0.05).@*CONCLUSIONS@#In patients with ADPKD after renal transplant, a higher dose of MPA is associated with a increased risk of UTI, and their plasma concentrations of immunosuppressants for long-term maintenance of immunosuppression regimen can be lower than those in other kidney transplantation recipients.

OBJECTIVE： To systematically evaluate the correlation between CYP3A5 6986A＞G gene polymorphism and blood concentration of Cyclosporine A （CsA） in Chinese renal transplant recipients. METHODS： Retrieved from Cochrane Library， PubMed， Embase， CBM， CNKI， VIP and Wanfang database， case-control or cohort studies about Chinese patients receiving CsA immunosuppressive therapy and blood concentration monitoring after kidney transplantation were collected. After literature screening and data extracting， the quality of literature was evaluated with Newcastle Ottawa scale， and Meta-analysis was performed by using Rev Man 5.3 software. RESULTS： Eight literatures with a total of 890 patients were involved in cohort study. Meta-analysis showed that the trough concentration after dosage correction （C0/D） of CsA in CYP3A5*1/*1 genotype was significantly lower than CYP3A5*1/*3 genotype[MD＝－6.97，95％CI     （－13.18，－0.76），P＝0.03]. The subgroup analysis showed that the C0/D of CsA in CYP3A5*1/*1 genotype was significantly lower than CYP3A5*1/*3 genotype when test time≤1 month after renal transplant [MD＝－8.50，95％CI（－12.57，－4.43），P＜0.000 1] and ＞1-＜6 months after renal transplant [MD＝－14.02，95％CI（－26.28， －1.76），P＝0.02]. C0/D of CsA in CYP3A5*1/*3 genotype was significantly lower than CYP3A5*3/*3 genotype [MD＝－6.04，95％CI（－8.99，－3.09），P＜0.000 1]. The subgroup analysis showed that C0/D of CsA in CYP3A5*1/*3 genotype was significantly lower than CYP3A5*3/*3 genotype when test time ≤1 month after renal transplant [MD＝－6.94，95％CI（－10.21， －3.68），P＜0.000 1]. C0/D of CsA in CYP3A5*1/*1 genotype was significantly lower than CYP3A5*3/*3 genotype [MD＝－12.64，95％CI（－21.09，－4.20），P＝0.003]. The subgroup analysis showed that C0/D of CsA in CYP3A5*1/*1 genotype was significantly lower than CYP3A5*3/*3 genotype when test time ≤1 month after renal transplant [MD＝－16.69，95％CI（－24.03，－9.36），P＜0.000 01] and ＞1-＜6 months after renal transplant [MD＝－16.78，95％CI（－28.63，－4.93），P＝0.006]. There was no statistical significance in CsA of peak concentration after dose correction between CYP3A5*1/*1 genotype and CYP3A5*1/*3 genotype， CYP3A5*1/*3 genotype and CYP3A5*3/*3 genotype， CYP3A5*1/*1 genotype and CYP3A5*3/*3 genotype. CONCLUSIONS： CYP3A5 6986A＞G gene polymorphism is associated with C0/D of CsA in Chinese renal transplantation recipients. The sequence of C0/D when test time ≤1 month after renal transplantation is as follows as CYP3A5*1/*1 genotype＜CYP3A5*1/*3 genotype＜CYP3A5*3/*3 genotype； during＞1-＜6 months after renal transplantation， C0/D of CsA in CYP3A5*1/*1 genotype＜CYP3A5*1/*3 genotype and CYP3A5*1/*1 genotype＜CYP3A5*3/*3 genotype.

Characteristics of BK polymavirus infection in kidney transplant recipients / 南方医科大学学报

OBJECTIVE@#To analyze the characteristics of BK polymavirus (BKV) infection and the optimal time window for intervention in kidney transplant recipients (KTRs).@*METHODS@#We retrospectively analyzed the clinical data and treatment regimens in 226 KTRs in our center between January, 2013 and January, 2018. Among the recipients, 157 had a urine BKV load ≥1.0×10 copy/mL after transplantation, and 69 had a urine BKV load below 1.0×10 copy/mL (control group).@*RESULTS@#Among the 157 KTRs, 60 (38.2%) recipients were positive for urine BKV, 66 (42.0%) had BKV viruria, and 31(19.7%) had BKV viremia. The incidence of positive urine occult blood was significantly higher in BKV-positive recipients than in the control group ( < 0.05). The change of urine BKV load was linearly related to that of Tacrolimus trough blood level (=0.351, < 0.05). In urine BKV positive group, the average estimated glomerular filtration rate (eGFR) was below the baseline level (60 mL·min·1.73 m) upon diagnosis of BKV infection reactivation, and recovered the normal level after intervention. In patients with BKV viruria and viremia, the average eGFR failed to return to the baseline level in spite of improvement of the renal function after intervention.@*CONCLUSIONS@#Positive urine occult blood after transplantation may be associated with BKV infection reactivation in some of the KTRs. BKV infection is sensitive to changes of plasma concentration of immunosuppressive agents. Early intervention of BKV replication in KTRs with appropriate dose reduction for immunosuppression can help to control virus replication and stabilize the allograft function.

The current situation of pharmacists in the hospital should be more taken into consideration during the legislative process in aspects of clearing and guaranteeing access qualifications, responsibilities,status,rights and interests,and pharmaceutical technology and service charges should be established.

Histone deacetylase 6 and cytoplasmic linker protein 170 function together to regulate the motility of pancreatic cancer cells

Pancreatic cancer is a devastating disease with the worst prognosis among all the major human malignancies. The propensity to rapidly metastasize contributes significantly to the highly aggressive feature of pancreatic cancer. The molecular mechanisms underlying this remain elusive, and proteins involved in the control of pancreatic cancer cell motility are not fully characterized. In this study, we find that histone deacetylase 6 (HDAC6), a member of the class II HDAC family, is highly expressed at both protein and mRNA levels in human pancreatic cancer tissues. HDAC6 does not obviously affect pancreatic cancer cell proliferation or cell cycle progression. Instead, it significantly promotes the motility of pancreatic cancer cells. Further studies reveal that HDAC6 interacts with cytoplasmic linker protein 170 (CLIP-170) and that these two proteins function together to stimulate the migration of pancreatic cancer cells. These findings provide mechanistic insight into the progression of pancreatic cancer and suggest HDAC6 as a potential target for the management of this malignancy.

End-binding protein 1 stimulates paclitaxel sensitivity in breast cancer by promoting its actions toward microtubule assembly and stability

Paclitaxel is a microtubule-targeting agent widely used for the treatment of many solid tumors. However, patients show variable sensitivity to this drug, and effective diagnostic tests predicting drug sensitivity remain to be investigated. Herein, we show that the expression of end-binding protein 1 (EB1), a regulator of microtubule dynamics involved in multiple cellular activities, in breast tumor tissues correlates with the pathological response of tumors to paclitaxel-based chemotherapy. In vitro cell proliferation assays reveal that EB1 stimulates paclitaxel sensitivity in breast cancer cell lines. Our data further demonstrate that EB1 increases the activity of paclitaxel to cause mitotic arrest and apoptosis in cancer cells. In addition, microtubule binding affinity analysis and polymerization/depolymerization assays show that EB1 enhances paclitaxel binding to microtubules and stimulates the ability of paclitaxel to promote microtubule assembly and stabilization. These findings thus reveal EB1 as a critical regulator of paclitaxel sensitivity and have important implications in breast cancer chemotherapy.
