ABSTRACT
Objective To study the effect of Bailing capsule on renal function and other organ systems in 60 patients after renal transplantation in No. 910 Hospital of Joint Logistics Support Force. Methods 60 patients with renal allograft in 2018−2020 were divided into 2 groups according to different immunosuppressive regimens. In the control group, 35 cases were treated with MMF + CsA or FK506; in the treatment group, 25 cases were treated with MMF + CsA or FK506 + Bailing capsule. Blood and urine routine, liver and renal function and uric acid were measured after operation. The dosage of immunosuppressive drugs was recorded in stages at 48 weeks. Results The urinary red and white blood cell counts, blood aspartate transaminase and alanine transaminase, serum uric acid, total bilirubin and direct bilirubin in the treatment group were significantly less than those in the control group, while the serum total protein and albumin were significantly higher than those in the control group. The number of red blood cells and white blood cells in the treatment group was significantly higher than that in the control group at 12-48 weeks after kidney transplantation, and that in the lymphocyte group was significantly higher than that in the control group at 24-48 weeks after kidney transplantation. The dosage of CsA and FK506 in the treatment group was significantly lower than that in the control group after 48 weeks. Conclusion Bailing capsule could protect liver and kidney, stimulate hematopoiesis, improve hypoalbuminemia and reduce the dosage of immunosuppressant, which could be an ideal immunomodulator.
ABSTRACT
Cyclosporine A, a cyclic polypeptide, exhibits potent immunosuppressive activity and exerts its effects through various mechanisms including immunosuppression, anti-inflammatory, inhibition of apoptosis, promotion of epithelial healing and goblet cell function recovery, enhancement of tear secretion, and close association with ocular surface disease repair. Owing to its significant efficacy, inhibition of disease recurrence and few side effects, the clinical application of cyclosporine A in the management of ocular surface diseases, including dry eye, corneal graft rejection following penetrating keratoplasty, vernal keratoconjunctivitis, noninfective keratitis and herpes simplex virus keratitis, has witnessed a substantial rise in recent years. Nevertheless, variations exist in the management of ocular surface inflammatory diseases when utilizing distinct concentrations and dosage forms of cyclosporine A. Therefore, the paper provides an overview of impacts of cyclosporine A on ocular surface diseases.
ABSTRACT
Ocular surface inflammatory disorder (OSID) is a chronic ocular disease caused by systemic disorders or involving the local immune system.OSID induces persistent inflammatory reaction in the ocular adnexal connective tissues which in turn give rise to tear hypertonicity and ocular surface epithelial damage, leading to dry eye formation or progression.Common immune-related ocular surface diseases include vernal keratoconjunctivitis, Sj?gren syndrome, graft versus host disease, dry eye and immune-related corneal disease, all of which can significantly impact the visual function and quality of life of patients.Current treatments including the use of artificial tears and glucocorticoid eye drops are not always effective and have the risk of adverse events.Cyclosporine A (CsA) is a commonly utilized immunosuppressant that has a strong immunomodulatory effect, but its clinical application is somewhat limited due to the low permeability of its current ophthalmic dosage form.The development of CsA ophthalmic agents has changed the treatment strategy for OSID.The development of 0.1% CsA cationic emulsion has significantly improved the efficacy and safety of topical CsA treatment, which is worth the attention.In order to rationally apply 0.1% CsA cationic emulsion to OSID, ophthalmologists should fully understand the immune-related pathogenesis of each OSID and comprehend the curative effect, indication, application methods and adverse events of topical CsA treatment.
ABSTRACT
OBJECTIVE@#To evaluate the efficacy, safety and relapse of cyclosporine A (CsA) and CsA combined with corticosteroid (CS) as the frontline therapy for patients with newly diagnosed acquired pure red cell aplasia (aPRCA).@*METHODS@#The clinical features, treatment responses, relapses and clinical outcomes of patients with newly diagnosed aPRCA in Peking Union Medical College Hospital (PUMCH) from January 2015 to May 2020 were analyzed retrospectively. All the enrolled patients had been treated with either CsA or CsA+CS for at least 6 months and had been followed up for at least 12 months, with complete clinical data and consent forms.@*RESULTS@#96 patients including 72 treated with CsA and 24 treated with CsA+CS were enrolled. With comparable baseline characteristics and follow-up periods, patients treated with CsA or with CsA+CS had similar overall response rates (ORRs) and complete response rates (CRRs) at the 3rd, 6th and 12th month and at the end of follow-up (P>0.05). Meanwhile, no significant difference was found between the two groups in the optimal ORR, optimal CRR, time to response or time to complete response. CsA+CS and CsA groups had similar adverse event (AE) rates, but CsA+CS group had higher CS-related infection rate (P <0.05). One patient in CsA+CS group died of multiple infections. As for the relapse, the two groups had compatible relapse rates at different time points, time to relapse, overall relapse rate and relapse-free survival (P>0.05). CsA exposure time, rather than different therapy regimens, was the only influence factor for either ORR or relapse rate (P <0.05).@*CONCLUSION@#CsA monotherapy has similar efficacy, AE rate and relapse rate as compared with CsA+CS for patients with newly diagnosed aPRCA, and shows less CS-related AEs such as infection.

AIM: To systematically evaluate the safety and efficacy of 0.05% cyclosporine A(CsA)in the treatment of dry eye.METHODS: PubMed, Web of Science, Cochrane Library, Embase, Chinese Bio-Medical Literature Database, CNKI, VIP, and Wan Fang Database were retrieved. Randomized controlled trials related to the treatment of dry eye with 0.05%CsA from January 1, 2016 to March 28, 2022 in each database were included. The CsA group was treated with 0.05% CsA eye drops, and the control group was treated with artificial tears and placebo. ReMan 5.3 was used for Meta-analysis of post-treatment Schirmer Ⅰ test(SⅠt), break up time(BUT), corneal fluorescein staining(CFS), ocular surface disease index(OSDI)and adverse effects.RESULTS: A total of 13 literatures were included, which included 1 164 cases(2 057 eyes). Compared with the control group, the SIt in the CsA group was prolonged(MD=2.04, 95%CI: 1.75~2.33, P&#x003C;0.00001), BUT was longer(MD=1.32, 95%CI: 0.87~1.76, P&#x003C;0.00001), CFS decreased(MD=-0.79, 95%CI: -1.20~-0.39, P=0.0001)and OSDI decreased(MD=-5.52, 95%CI: -9.14~-1.91, P=0.003). However, the CsA group had more adverse reactions(OR=1.69, 95%CI: 1.06~2.72, P=0.03).CONCLUSION: 0.05% CsA can improve the subjective symptoms and various objective indicators of dry eye patients. However, 0.05% CsA seems to produce more adverse effects, like ocular burning sensation when compared to drugs such as artificial tears.
ABSTRACT
OBJECTIVE To compare the efficacy, safety and economy of tacrolimus (TAC), cyclosporin A (CsA), cyclophosphamide (CTX) and rituximab (RTX) in the treatment of membranous nephropathy (MN). METHODS Retrieved from Pubmed, the Cochrane Library, Wanfang data, CNKI and health technology assessment (HTA) official website, HTA reports, systematic reviews/meta-analysis and pharmacoeconomic studies about TAC, CsA, CTX and RTX combined with glucocorticoid in the treatment of MN were collected during the inception and Mar. 2022. After data extraction and quality evaluation, descriptive analysis was performed on the results of the included studies. RESULTS A total of 15 articles were included, involving 13 systematic reviews/meta-analysis and 2 pharmacoeconomic studies. In terms of efficacy, TAC and CsA showed significant advantages in increasing the response rate, and could improve the levels of urine protein, serum albumin, serum creatinine and serum total cholesterol. In terms of safety, the incidence of adverse reaction induced by TAC, CsA and RTX was low and the symptoms were mild. In terms of economics, CTX cost lower but caused severe adverse reaction; TAC cost higher but showed higher remission rate and good safety. CONCLUSIONS TAC combined with glucocorticoid may be the recommended scheme for MN.
ABSTRACT
ABSTRACT Purpose: The aim of this study was to compare the effects of topical cyclosporine 0.1% and bevacizumab on experimentally induced corneal neovascularization in a rat model. Methods: A total of 30 adult Sprague-Dawley rats were used in this experimental study. The central cornea of the rats was cauterized chemically. The rats were randomly enrolled into three groups as follows: Group 1 received bevacizumab 1%, Group 2 received cyclosporine 0.1%, and Group 3 received isotonic saline twice a day for 28 days. Slit-lamp examination of all rats was performed at the 3rd and 28th day. The rats were then sacrificed, and the corneas were excised. The number of blood vessels, state of inflammation, and collagen formation were evaluated histopathologically in the corneal sections. Results: Corneal opacity and edema grades were significantly lower in Group 2 than in Group 3 (p=0.04 and 0.00, respectively). In the histopathological examination, Group 2 demonstrated significantly lesser number of blood vessels than Group 3 (p=0.001). Regarding collagen formation, Group 2 exhibited more regular collagen formation than Groups 1 and 3 (p=0.03). Inflammation grades were significantly lower in Groups 1 and 2 than in Group 3 (p=0.014 and 0.001, respectively). Conclusion: Topical bevacizumab is effective in inhibiting newly formed corneal neovascularization. The topical cyclosporine 0.1% treatment appears to be more effective than the topical bevacizumab treatment.
RESUMO Objetivo: Comparar os efeitos da ciclosporina tópica 0,1% e do bevacizumabe na neovascularização da córnea produzida experimentalmente em um modelo com ratos.

Os ratos foram distribuídos aleatoriamente em três grupos. O grupo 1 recebeu bevacizumabe a 1%, o grupo 2 recebeu ciclosporina tópica a 0,1% e o grupo 3 recebeu solução salina isotônica duas vezes ao dia durante 28 dias. O exame de lâmpada de fenda de todos os ratos foi realizado no terceiro e no vigésimo oitavo dias. Os ratos foram então sacrificados e as córneas excisadas. Nos cortes da córnea, o número de vasos sanguíneos, o estado de inflamação e a formação de colágeno foram avaliados em uma análise anatomopatológica. Resultados: No Grupo 2, os graus de opacidade e de edema da córnea foram significativamente menores que no Grupo 3 (p=0,04 e 0,00, respectivamente). No exame histopatológico, o Grupo 2 apresentou um número significativamente menor de vasos sanguíneos do que o Grupo 3 (p=0,001). Em relação à avaliação da formação de colágeno, esta mostrou-se mais regular no Grupo 2 que no Grupo 1 e no Grupo 3 (p=0,03). Os graus de inflamação foram significativamente menores no Grupo 1 e no Grupo 2 em comparação com o Grupo 3 (p=0,014 e 0,001, respectivamente). Conclusão: O bevacizumabe tópico é eficaz na inibição da neovascularização da córnea recém-formada. O tratamento tópico com ciclosporina a 0,1% parece ser mais eficaz em comparação ao tratamento tópico com bevacizumabe.
ABSTRACT
The main purpose of our study was to evaluate the efficacy and safety of eltrombopag plus cyclosporine A (CsA) in transfusion-dependent non-severe aplastic anemia(TD-NSAA). The clinical characteristics of 13 TD-NSAA patients who received initial treatment of eltrombopag plus CsA from 2019 to 2021 were retrospectively analyzed. The 3-month overall hematological response (OR) rate was 12/13. Until the end of follow-up, 12 patients responded, among whom 2 patients reached complete response (CR) and 9 patients reached partial response (PR) and 1 with HR. Paroxysmal nocturnal hemoglobinuria (PNH) developed in one patient at 6 months after treatment. Five of thirteen patients reported mild adverse reactions, which were all manageable. Compared with historical data, the combination of eltrombopag with CsA is an effective regimen in patients with TD-NSAA.
ABSTRACT
Objectives:To establish a candidate reference measurement procedure based on isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) for cyclosporin A, tacrolimus, sirolimus, and everolimus measurements in human whole blood.Methods:The isotope labeled cyclosporine A, tacrolimus, sirolimus, and everolimus were selected as the internal standards. Samples were accurately weighed while protein precipitation and solid phase extraction were selected for the sample preparation. The standard curve method was applied for quantification. The ultra-high liquid chromatography coupled with triple quadrupole mass spectrometer was used for analysis. The specificity, matrix effect, detection limit, quantification limit, precision, accuracy, and uncertainty of the method were evaluated.Results:The method showed good selectivity and specificity. No apparent interferences or matrix effects were found in the target analyte measurements. The detection limits and quantification limits of cyclosporin A, tacrolimus, sirolimus and everolimus met clinical requirements. Intra-batch coefficients of variation ( CV) were from 1.4% to 1.8% for CSA, from 1.7% to 2.8% for TAC, from 1.3% to 3.7% for SRL and from 2.3% to 3.2% for EVR, and total CVs were from 1.8% to 2.9% for CSA, from 1.7% to 3.8% for TAC, from 2.6% to 4.7% for SRL and from 3.5% to 4.6% for EVR. The relative recoveries were from 97.9% to 100.3% for CSA, from 98.4% to 103.1% for TAC, from 99.4% to 102.0% for SRL and from 98.3% to 99.4% for EVR, and the relative expanded uncertainties at four concentrations were from 4.2% to 4.4% for CSA, from 1.5% to 2.4% for TAC, from 4.4% to 4.9% for SRL and from 2.2% to 2.7% for EVR. Conclusion:A candidate reference measurement procedure for the cyclosporine A, tacrolimus, sirolimus, and everolimus in human whole blood was established by ID-LC-MS/MS.
ABSTRACT
Cyclosporine A is widely used in organ transplantation and autoimmune diseases . Due to the obvious differences in metabolism between individuals ,the dosage should be adjusted according to the patient ’s blood concentration during clinical use . But the blood concentration does not reflect accurately its clinical prognosis . This article focuses on the four laboratory examination indexes following aspects :the cyclosporine A concentration of peripheral blood mononuclear cells ,calcineurin activity ,T cell function and metabolite concentration of cyclosporine A . The relationship between them and the pharmacokinetics of cyclosporine and clinical prognosis were reviewed . It’s found that the above indicators have a certain predictive effect on the clinical prognosis of patients receiving cyclosporine A ,which can make up for the insufficiency of blood drug concentration monitoring ,and the clinical practicability needs to be further improved .

ABSTRACT
Accurate determination of drug concentration in blood samples is a necessary prerequisite for therapeutic drug monitoring (TDM) and the implementation of precise drug treatment, and it is also one of the important tasks of clinical laboratories.TDM plays an important role in clinical treatment in immunosuppressants (cyclosporine A, tacrolimus), psychotropic drugs (valproic acid, carbamazepine) and other drugs that require monitoring of drug concentration. There are many types of methods used for TDM for the detection of drug concentration in blood samples. At present, only a few immuno-assay methods were approved for marketing with detection systems and kits, most methods used for TDM are high performance liquid chromatography or liquid chromatography-tandem mass spectrometry which belong to laboratory developed tests (LDTs). Detection of TDM samples has many problems, such as incomparable testing results and large bias between different testing systems, including the biasbetween both different methods and different laboratories using the same method. There are several reasons:(1) the traceability chain has not been established, (2) the methods have not yet been standardized, (3) the coverage of the EQA plan is insufficient, (4) the awareness of TDM laboratories to participate in the EQA plan is insufficient, (5) TDM standardization is still in its infancy. These problems restrict the clinical application of TDM and the development of related research work. In order to solve these problems, it is necessary to: (1) Establish a reference system to realize the traceability of the test results; (2) While gradually increasing the TDM EQA plan items, the Trueness evaluation plan should be carried out as soon as possible; (3) Standardized TDM sample testing Technology; (4) Strengthen laboratory management and establish a complete quality management system.
ABSTRACT
OBJECTIVE@#To investigate the effects of topical administration of cyclosporine A (CsA) on salivary secretion and inflammation of the submandibular glands in non-obese diabetic (NOD) mice.@*METHODS@#Female NOD mice, 21 aged 14 weeks and 18 aged 21 weeks were selected and randomly divided into low-dose group, high-dose group and control group on average. CsA was injected into submandibular glands. One week later the saliva stimulated by pilocarpine was collected and measured. The submandibular glands were collected to make paraffin sections. The lymphocyte infiltration in submandi-bular gland was observed by microscope after hematoxylin-eosin (HE) staining. The number of lymphocyte infiltration foci was counted to calculate the focus sore and the ratio of lymphocyte infiltration area to total gland area was figured up by Leica image analysis system. The expressions of inflammatory cytokines tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-4 (IL-4), IL-13, IL-17F, IL22 and IL-23a in the submandibular glands of the NOD mice were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell apoptosis in the submandibular gland was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). The levels of serum creatinine (Scr), blood urea nitrogen (BUN), uric acid (UA), alanine aminotransferase (ALT), aspertate aminotransferase (AST), alkaline phosphatase (ALP), albumin (ALB) and γ-glutamyl transferase (GGT) were measured by automatic biochemical analyzer to evaluate liver and kidney functions.@*RESULTS@#After topical injection of CsA in the submandibular gland, the stimulated salivary flow rate of the 14- and 21-week-old NOD mice significantly increased compared with the control group (P < 0.01 or P < 0.05), and the number and area of lymphocyte infiltration foci in the 14-week-old NOD mice low-dose group significantly decreased compared with the control group (P < 0.01). Low and high dose of CsA had similar effects on reducing inflammation and improving salivary secretion. The overall level of inflammatory cytokines in the submandibular gland did not decrease significantly. The number of cell apoptosis of submandibular gland in the NOD mice treated with CsA decreased compared with the control group, but there was no statistically significant difference. Topical injection of CsA had no adverse effect on liver and kidney function in the NOD mice.@*CONCLUSION@#Topical injection of CsA can reduce lymphocyte infiltration in submandibular gland of NOD mice and improve salivary secretion.

Type 1 diabetes (T1D) is a chronic autoimmune disordercharacterized by specific immune destruction of the insulinproducing pancreatic β-cells. The loss of β cells involves bothgenetic and ill-defined environmental factors. The highest riskHLA-DR3/4 DQ8 genotype has been shown to be highlyassociated with β-cell autoimmunity and benign insulinitis.Subsequently; catalysts viz. viruses transform predisposedsubjects into overt diabetics. Such autoimmunity is herald byautoantibodies and subsequently low C-peptide production.Hence, there is no ideal autoimmune therapy for T1D sincepatients are genetically predisposed. Previous autoimmunemeasures to suppress early transformations were crippled bylong-term complications of medications. In our case report; welimited the use of Cyclosporine A to 1 year in a patient and itwas cost effective.
ABSTRACT
Objective: To analyze the prognostic factors of transfusion-dependent non-severe aplastic anemia (TD-NSAA) patients treated with cyclosporine A (CsA) and androgen. Methods: Clinical data of 77 consecutive TD-NSAA patients treated with CsA and androgen were retrospectively analyzed between 2010 and 2013. We obtained clinical manifestations and baseline parameters of routine blood test from responders, and compared those with non-responders. All data were analyzed by univariate analysis and multivariate analysis. Results: In 77 patients, there were 43 (55.8%) patients achieved hematological response after 6 months'treatment, and 53 (68.8%) patients got response after 12 months. Univariate analysis showed that platelets baseline was the only factor related to hematological response [19 (6-61) ×10(9)/L vs 13.5 (5-45) ×10(9)/L, P=0.001] after 6 months therapy. After 12 months, the statistical differences were maintained, which were platelets baseline [18 (6-61) ×10(9)/L vs 10.5 (5-45) ×10(9)/L, P<0.001], absolute reticulocytes [0.03 (0.01-0.06) ×10(12)/L vs 0.029 (0.02-0.06) ×10(12)/L, P=0.043], transfusion-dependent of platelet (P=0.007) , transfusion-dependent of platelet and erythrocyte (P=0.012) . Multivariate analysis showed that platelets baseline could be an independent prognostic factor of hematological response (P=0.010 or 0.009) . Cutoff value of platelets by receiver operating characteristic curve was 15.5×10(9)/L. Conclusion: Baseline of higher platelets, higher reticulocyte, and no transfusion dependence of platelet are favorable prognostic factors. When platelets baseline is higher than 15.5×10(9)/L, CsA and androgen regimen is rational.

OBJECTIVE: To establish a method for simultaneous quantitative determination of 14 bile acids in human plasma by liquid chromatograohy-tandem mass spectrometry (LC-MS/MS) and to explore the correlation between the hepatotoxicity induced by cyclosporine A and bile acids. METHODS: Plasma samples were extracted by protein precipitation and bile acids were separated on a Waters ACQUITY UPLC HSS T3(2.1 mm×150 mm,1.8 μm) column with a flow rate of 0.3 mL•min-1. The mobile phase was water (containing 4 mmol•L-1 ammonium acetate) and 95% acetonitrile using gradient elution in 15 min. The detection system used an electrospray ion source in negative ion mode. RESULTS: Fourteen bile acids had a good linear relationship, the intra-and inter-assay RSD values were less than 15%, the accuracy was between 87% and 116%, and the extraction recovery rates of the quality was between 101% and 120%. The concentration of cholic acid (CA) was well correlated with cyclosporine A and suggested that bile acids may be associated with the hepatotoxicity induced by cyclosporine A. CONCLUSION: This LC-MS/MS method for quantitatively determining various bile acids in human plasma is convenient, accurate and sensitive and can be used for further basic research in hepatotoxicity caused by cyclosporine A.

ABSTRACT
Coronavirus mainly causes local infection in birds and mammals. In recent decades, there has been an evidence that it can infect humans. Highly pathogenic coronavirus, including severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), are fatal zoonotic viruses, which have posed a major threat to public health. Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2, COVID-19) has also seriously endangered the health and safety of the human beings. These coronaviruses transmit through close contact between people, resulting in the development of acute respiratory distress syndrome (ARDS) and multiple organ failure (MOF) and having a higher morbidity and mortality. This article reviews the structure, epidemiology, immunology and treatment of the coronavirus, hoping to provide reference for the prevention, control and treatment of the disease.

ABSTRACT
Alzheimer's disease (AD) is one of the most common dementia causes especially in elders. Black raisins (Vitis vinifera) have memoryenhancing effects. This study was designed to investigate the effect of oral administration of black raisins (V. vinifera) on aluminumchloride (AlCl3) induced AD in male albino rats. Forty adult male Albino rats were equally and randomly divided into five groups, 8 rats ineach. The rats of the first group received a vehicle and served as controls. The animals of the second group received raisin (5 g per rat/day)orally for 8 weeks. The rats in the third group were treated with AlCl3 (model of AD) (100 mg/kg BW/day) for 8 weeks. The animals of thefourth group were treated with AlCl3 (100 mg/kg BW/day) and raisin. The animals of the fifth group received rivastigmine (0.3 mg/kgBW/day) and AlCl3 (100 mg/kg BW/day) orally for 8 weeks. After eight weeks, the behavioral test (maze learning test) was performed on allrats to assess learning and memory. Moreover, acetylcholinesterase (AchE) activity, some neurotransmitter levels [dopamine (DA),norepinephrine (NE), gamma-aminobutyric acid (GABA)], and oxidative stress [reduced glutathione (GSH), superoxide dismutase (SOD),oxidase glutathione (GSSG), and lipid peroxidation (LPO)] were estimated in the cortex and hippocampus homogenate. Thehistopathological studies were also made in the hippocampus area. The results showed that aluminum exposure significantly decreased thelearning and memory in the maze-learning test as revealed by increase in elapsed time and error number in the maze. Significant increaseof cortex and hippocampus homogenate levels of AchE and LPO, but a significant decrease in DA, NE, GABA, GSH, GSSG, and SOD wereobserved in rats subjected to AlCl3. Histopathological evaluations of hippocampus sections of rats treated with AlCl3 showed severealterations including the increase of degenerated cells with structural damage. The treatment of rats with raisin or rivastigmine for 8 weeksshowed a pronounced attenuation on the damage caused by AlCl3 associated with the improvement of behavioral, biochemical, andhistopathological alterations. This study suggested that chronic oral administration of black raisin had neuroprotective effects andimproved learning and memory in AD animal models. These actions were done due to the antioxidant constituents of raisin.
