After kidney transplantation, the recipients have been under long-term immunosuppression due to the use of immunosuppressive drugs, and they are high-risk population of Pneumocystis jirovecii pneumonia (PJP). The risk of PJP is the highest within 6 months after kidney transplantation and after intensified anti-rejection therapy. Fever, dry cough, progressive dyspnea and hypoxemia are common clinical manifestations of PJP after kidney transplantation. Trimethoprim-sulfamethoxazole (TMP-SMX) can effectively prevent and treat PJP, and significantly reduce the incidence rate and fatality of PJP. To standardize the diagnosis, treatment and prevention of PJP after kidney transplantation, Branch of Organ Transplantation of Chinese Medical Association organized relevant Chinese experts to formulate the " Guidelines for Clinical Diagnosis and Treatment of Pneumocystis Jirovecii Pneumonia After Kidney Transplantation in China" based on clinical concerns, aiming to provide guidance for the prevention and comprehensive clinical treatment of PJP after kidney transplantation.

The application of combination antiretroviral therapy (cART) has significantly prolonged the life expectancy of patients infected with human immunodeficiency virus (HIV). However, viral infection and adverse reactions of cART drugs make patients more prone to organ failure. Solid organ transplantation has become a standard treatment for HIV-infected patients with end-stage organ failure. Nevertheless, among HIV-positive soild organ transplant recipients, multiple problems remain to be resolved, such as increased incidence of graft rejection, increased infection risk, drug toxicity and drug interaction between cART therapy and immunosuppressive drugs, etc. It is extremely challenging to deliver appropriate management for HIV-positive soild organ transplant recipients. Therefore, the application of immune induction therapy, calcineurin inhibitors, mammalian target of rapamycin (mTOR) inhibitors and other immunosuppressive drugs in HIV-positive soild organ transplant recipients was reviewed, aiming to provide reference for subsequent management of immunosuppression in HIV-positive soild organ transplant recipients.

Objective To investigate the characteristics of adverse drug event (ADE) related to tacrolimus (Tac) in pediatric solid organ transplant recipients. Methods The data were retrieved from the US Food and Drug Administration Adverse Event Reporting System database from the first quarter of 2004 to the second quarter of 2023. The ADE data of pediatric organ transplant recipients with Tac as the primary suspected drug were extracted. The relationship between Tac and ADE was quantitatively analyzed by proportional imbalance method. Basic characteristics and signal strength of ADE related to Tac were analyzed. ADE related to Tac in children of different ages and different types of organ transplantation were analyzed. Results A total of 1 443 children's ADE reports involving Tac were screened, including 188 cases (13.0%) of heart transplantation, 668 cases (46.3%) of liver transplantation, 531 cases (36.8%) of kidney transplantation and 56 cases (3.9%) of lung transplantation. The median age of children was 10 years old. The top three countries with ADE reporting were the United States, France and the United Kingdom. China reported 26 cases, accounting for 1.8%. Infection and infectious diseases accounted for the highest proportion (20.96%) in ADE related to Tac, including EB virus and cytomegalovirus infection, etc. Infection and infectious diseases occupied the largest proportion of ADE related to Tac in children of different ages, whereas the pathogen types were different. Rejection, unstable immunosuppression level and renal function damage were also common ADE related to Tac in children of all ages. Nervous system disease was the main ADE in heart transplant recipients, while infection and infectious diseases were more common in liver and kidney transplant recipients. Rejection was the most common ADE in lung transplant recipients.Conclusions ADE related to Tac possess different distribution characteristics in different types of organ transplantation. Extensive attention should be paid to individualized drug monitoring and risk assessment in pediatric organ transplant recipients, thereby optimizing Tac treatment and reducing the risk of ADE.

As a marginal organ donor, organs from hepatitis C donors have been applied in solid organ transplantation. While effectively alleviating the shortage of organs, it also faces certain challenges, such as the spread of hepatitis C virus (HCV). With the emergence and application of direct-acting antiviral agent, the cure of hepatitis C has gradually become a reality, laying the foundation for hepatitis C patients to become organ transplant donors. At present, with adjuvant treatment using antiviral drugs, certain efficacy has been achieved in solid organ transplantation from hepatitis C donors. In this article, research progress in kidney, heart, lung and liver transplantation from hepatitis C donors, the application of hepatitis C donors in solid organ transplantation and the safety and effectiveness of antiviral drugs were reviewed, and the feasibility of hepatitis C donors in solid organ transplantation was evaluated, aiming to provide reference for expanding the donor pool of organ transplantation and shortening the waiting time for organ transplantation in patients with end-stage diseases.

With widespread application of solid organ transplantation (SOT), the incidence of postoperative invasive fungal disease (IFD) in SOT recipients has been increased year by year. In recent years, the awareness of preventive antifungal therapy for SOT recipients has been gradually strengthened. However, the problem of fungal resistance has also emerged, leading to unsatisfactory efficacy of original standardized antifungal regimens. Drug-drug interaction and hepatorenal toxicity induced by drugs are also challenges facing clinicians. In this article, the characteristics of drug-drug interaction and hepatorenal toxicity among triazole, echinocandin and polyene antifungal drugs and immunosuppressants were reviewed, and postoperative preventive strategies for IFD in different types of SOT recipients and treatment strategies for IFD caused by infection of different pathogens were summarized, aiming to provide reference for physicians in organ transplantation and related disciplines.

Tacrolimus has been accepted as the first-line drug of immunosuppressive therapy after solid organ transplantation, with the macrolide chemical structure, which is mainly used for prophylaxis of rejection in liver, kidney, heart, lung or bone marrow transplantation treatment. Based on the characteristics of narrow therapeutic window, large inter-and intra-individual variances, multiple influencing factors of drug exposure, drug monitoring is widely recommended for tacrolimus in drug instructions, clinical guidelines and literature. Drug therapy is a patient-centered and clinical-dominated multidisciplinary technical work. The information in tacrolimus drug instructions cannot cover all the issues in clinical practice. As important supplements to medical documents, clinical guidelines and expert consensus are conducive to solving clinical problems and benefiting patients. "Expert Consensus on Individual Treatment of Tacrolimusin Solid Organ Transplantation"（ hereinafter referred to as"the consensus"） drafting expert group analyzed 54 tacrolimus-related guidelines and expert consensus before 2020, and concluded that it is necessary for medical multidisciplinary cooperation to comprehensively, systematically and in-depth explain the role of tacrolimus in solid organ transplantation. The expert group not only put forward urgently needed technical support and thoroughly resolved treatment issues from clinical perspective, but clarify the drug treatment elements of concern and the pharmacist responsibility list of pharmaceutical care from pharmacological perspective, so as to strengthen the rational use of tacrolimus and improve the benefits of patients. The consensus was jointly drafted by clinical clinicians and pharmacists. The main text includes four parts: preface, clinical application, drug monitoring and clinical pharmacists, covering immunosuppressive therapy for liver, kidney, heart and lung transplantation, including clinical therapeutic targets, plasma concentration monitoring, gene polymorphism determination and drug interactions. The active participation of clinical pharmacists is helpful for individualized tacrolimus treatment. According to the experience of many organ transplantation centers in China, the consensus put forward suggestions for clinical pharmacists in organ transplantation, so as to improve the quality of pharmaceutical care and optimize the individualized tacrolimus treatment.

Objective To investigate the efficacy and safety of programmed cell death protein-1 (PD-1) monoclonal antibody on the treatment of malignant tumor after solid organ transplantation (SOT). Methods The relevant literatures in 7 databases were searched. The data on 54 cases of recipients with malignant tumors treated with PD-1 monoclonal antibody after SOT were collected, and the clinical effects and rejection of SOT recipients treated with PD-1 monoclonal antibody were analyzed. Results Total 32 acceptable articles including 54 SOT recipients were incorporated, including 43 males and 11 females aged 14-79 years old. There are 29 renal transplant recipients, 19 liver transplant recipients and 6 heart transplant recipients. The types of PD-1 monoclonal antibody agent used by SOT recipients included pembrolizumab for 28 patients and nivolumab for 26 patients. The overall remission rate, disease progression rate and fatality rate of PD-1 monoclonal antibody for postoperative malignant tumors of SOT recipients were 32% (17/54), 44% (24/54) and 36% (19/54), respectively. After treatment with PD-1 monoclonal antibody for postoperative malignant tumors of SOT recipients, the incidence of rejection was 39% (21/54), indicating no significant correlation between rejection and type of PD-1 monoclonal antibody (P>0.05). Conclusions PD-1 monoclonal antibody can effectively treat postoperative malignant tumors of SOT recipients, and may induce rejection during the treatment. But rejection is not the most common cause for death of recipients. [ABSTRACT FROM AUTHOR]
