RÉSUMÉ

BACKGROUND Cesarean scar ectopic pregnancy is a rare type of ectopic pregnancy that can result in severe maternal morbidity and mortality. Medical, surgical, and minimally invasive therapies alone or in combination have been described in the literature, but the optimal treatment modality of cesarean scar ectopic pregnancies is unknown. Limited information exists on the course of cesarean scar ectopic pregnancy following treatment with cytotoxic agents. CASE REPORT We present a case of a woman with a history of multiple cesarean births that was provided with medical abortion for an unintended pregnancy. However, upon follow-up, the patient was found to have a cesarean scar ectopic pregnancy. Following the diagnosis, she was treated by multi-dose systemic methotrexate-leucovorin and with ultrasound-guided intra-gestational sac injection of potassium chloride. After resolution of beta human gonadotropin levels, ultrasound follow-up revealed persistence of residual tissue in the cesarean scar. The patient elected for resection of the residual tissue with operative hysteroscopy. We report a novel hysteroscopic finding after medical treatment of a cesarean scar ectopic pregnancy with intra-gestational sac injection of potassium chloride. CONCLUSIONS Direct visualization of the intra-abdominal cavity and intra-uterine cavity showed that combined medical management with systemic methotrexate and local potassium chloride injection is an effective treatment modality for live cesarean scar ectopic pregnancies, with minimal anatomical harm. Hysteroscopic resection offers a safe and effective approach for removal of persistence of residual tissue.

RÉSUMÉ

Analyze the relationship between genetic variations in the MTHFR gene at SNPs (rs1801131 and rs1801133) and the therapy outcomes for Iraqi patients with rheumatoid arthritis (RA). The study was conducted on a cohort of 95 RA Iraqi patients. Based on their treatment response, the cohort was divided into two groups: the responder (47 patients) and the nonresponder (48 patients), identified after at least three months of methotrexate (MTX) treatment. A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was employed to analyze the MTHFR variations, specifically at rs1801133 and rs1801131. Overall, rs1801131 followed both codominant and dominate models, in which in the codominant model, GG [OR (95% CI) 0.11 (0.022-0.553)] and TG [OR (95% CI) 0.106 (0.021-0.528)] predict responders compared to the TT genotype; meanwhile, for the dominate model, the presence of both GG and TG genotypes [OR (95% CI) 0.108 (0.023-0.507)] together predict responders compared to the TT genotype. The Ars1801133Grs1801131 haplotype was significantly associated with responders [OR (95% CI): 0.388 (0.208-0.723)], while the Grs1801133Trs1801131 haplotype was associated marginally with nonresponders [OR (95% CI) 1.980 (0.965-4.064)]. In the final multivariate analysis, GG/TGrs1801131 genotypes were independently related to responders after adjustment for patients, disease, and treatment characteristics, while TTrs1801131 genotypes were associated with nonresponders. The Iraqi RA patients showed genetic polymorphism in MTHFR gene rs1801131 with T carrier allele associated with nonresponders to MTX therapy. The rs1801131 followed both codominant and dominant models. The G-carried allele for rs1801131 showed an independent association with responder to MTX therapy after adjustment for patients, disease, and treatment characteristics.

RÉSUMÉ

BACKGROUND: Non-tubal ectopic pregnancies account for < 10% of all ectopic pregnancies. Due to its rarity and wide variation in clinical practice, there is no guideline or consensus for its management. We reported our 20-year experience in the management of non-tubal ectopic pregnancies in a tertiary hospital. METHODS: This is a retrospective review of all women admitted for non-tubal ectopic pregnancies from January 2003 to December 2022 in a tertiary hospital. Women with non-tubal ectopic pregnancies diagnosed by ultrasound or operation were included for analysis. RESULTS: Within the study period, 180 women were diagnosed to have non-tubal ectopic pregnancies at a mean gestation of 6.8 weeks. 16.7% (30/180) were conceived via assisted reproduction. Medical treatment was the first-line management option for 81 women, of which 75 (92.1%) women received intralesional methotrexate administered under transvaginal ultrasound guidance. The success rate of intralesional methotrexate ranges from 76.5% to 92.3%. Intralesional methotrexate was successful even in cases with a positive fetal pulsation or with high human chorionic gonadotrophin levels up to 252605U/L. Twenty seven women were managed expectantly and 40 underwent surgery. Nine (11.1%), two (6.1%), and one (2.3%) women required surgery due to massive or recurrent bleeding following medical, expectant, or surgical treatment. Hysterotomy and uterine artery embolization were necessary to control bleeding in one Caesarean scar and one cervical pregnancy. CONCLUSIONS: Intralesional methotrexate is more effective than systemic methotrexate and should be considered as first line medical treatment for non-tubal ectopic pregnancies. It has a high success rate in the management of unruptured non-tubal ectopic pregnancies even in the presence of fetal pulsations or high human chorionic gonadotrophin levels, but patients may require a prolonged period of monitoring. Close surveillance and readily available surgery were required due to the risk of heavy post-procedural intra-abdominal bleeding.

RÉSUMÉ

Febrile ulceronecrotic Mucha-Habermann disease is a rare and severe variant of pityriasis lichenoides, characterized by sudden onset of generalized ulceronecrotic papules that rapidly coalesce into ulcers associated with high fever. Systemic manifestations such as intravascular disseminated coagulation and pulmonary, cardiac, gastrointestinal, and central nervous system involvement are common. Treatment is based on oral corticosteroids, immunosuppressive drugs such as methotrexate, and general supportive treatment. The present case describes a stepwise approach to a patient with Mucha-Habermann disease with insufficient response to methotrexate.

RÉSUMÉ

BACKGROUND: Psoriasis has a global prevalence of 1-3%, with variations observed across different ethnic groups and geographical areas. Disease susceptibility and response to anti-tumor necrosis factor-α (TNFα) drugs suggest different genetic regulatory mechanisms which may include NLR family pyrin domain containing 3 (NLRP3) polymorphism. Evaluation of the NLRP3 gene polymorphism, the serum level of CRP and TNFα in psoriasis patients and assessment of the NLRP3 (rs10754558) gene polymorphism, CRP and TNFα with disease severity and their role as biomarkers for response to Methotrexate and Adalimumab in psoriasis. The study had a total of 75 patients diagnosed with psoriasis vulgaris, who were compared to a control group of 75 healthy individuals. RESULTS: There was a highly significant difference in NLRP3 genotypes and alleles distribution between psoriasis patients and controls (P = 0.002,0.004). The heterozygote genotype GC (OR = 3.67,95%CI:1.75-7.68, P = 0.0006), was linked with increased risk of psoriasis. Additionally, The GC genotype was significantly associated with nonresponse to psoriasis therapy (OR = 11.7,95%CI:3.24-42.28, P = 0.0002). Regarding serum CRP and TNFα levels, there was a highly statistically significant difference between psoriasis patients and controls (P < 0.0001), and there was also a highly statistically significant difference between responders and non-responders in psoriasis patients regarding PASI 50 (P < 0.0001). CONCLUSIONS: The NLRP3 (rs10754558) genotypes GC was associated with the severe form of psoriasis and with nonresponse to psoriasis medication. Therefore, NLRP3 (rs10754558) gene polymorphism is an important prognostic biomarker in psoriasis patients. The serum TNFα can be used as a predictor for response to therapy in psoriasis patients. More research for evaluation of role of the NLRP3 gene polymorphism in the genetic risks and treatment outcomes associated with psoriasis is still required.

RÉSUMÉ

INTRODUCTION: Severe cutaneous adverse reactions (SCARs) arising from drug interactions can carry life-threatening implications and result in lasting effects. SCARs can be triggered by various factors, with trimethoprim/sulfamethoxazole identified as a primary culprit. Anticonvulsants and antineoplastic agents have been noted as secondary triggers. Notably, antineoplastics linked to SCARs include immunomodulatory agents. The higher mortality rates among cancer patients with SCARs underscore the significance of comprehending cancer--specific risk factors. Our objective is to present the case of a boy with acute lymphocytic leukemia (ALL) who developed Stevens-Johnson syndrome (SJS) following MTX treatment. CASE REPORT: We present the case of a three-year-old male patient diagnosed with ALL who developed Stevens-Johnson syndrome (SJS) subsequent to the administration of MTX, following the "BFM 2009" protocol. He had undergone intrathecal MTX administration on six previous occasions. Our patient received IVIG at a dose of 2g/kg along with steroids, resulting in partial clinical improvement after 21 days. An innovative protocol was developed, involving IVIG before MTX infusion and dexamethasone before MTXi, with folinic acid rescue. Intravenous immunoglobulin (IVIG) mitigates SJS/TEN via type IV hypersensitivity down-regulation and apoptosis curbing. CONCLUSION: As far as we know, the prophylactic use of IVIG to counteract SCARs in a pediatric leukemia patient represents uncharted territory. Moreover, research into the immune system dynamics within these patients and the preservation of indispensable treatments should involve allergist-immunologists as part of the multidisciplinary team attending to neoplastic conditions.

RÉSUMÉ

Pityriasis Rubra Pilaris is a rare, chronic inflammatory dermatosis of unknown etiology, presenting with erythema and papular eruptions. Treatment is difficult due to the lack of causal therapy, guidelines and requires an individualized approach. The most common treatments are systemic retinoids, immunosuppressants, phototherapy and biological therapy. This article presents the case of a 73-year-old man suffering from type 1 pityriasis rubra pilaris. The patient was initially treated with acitretin, which was discontinued due to hypogammaglobulinemia. This rare side effect of acitretin has not been previously published. As a second-line treatment, the patient received methotrexate, but with no clinical improvement after 3 months and an increase in skin pruritus. Finally, the use of isotretinoin resulted in significant clinical improvement and was well tolerated.

RÉSUMÉ

BACKGROUND: Ectopic pregnancy (EP) can be treated surgically or nonsurgically. In many countries, methotrexate is frequently used as a first-line medical treatment, and its effect is similar to that of surgery in selected patients. We aimed to investigate national trends in the treatment of EP in Japan. METHODS: We conducted a retrospective observational analysis between 2010 and 2020 using a nationwide claims database that included inpatient data. We identified female inpatients with EP aged 15 to 49 years old. We analysed year-to-year treatment trends for EP, as well as year-to-year trends in methotrexate administration, with a focus on the site of the pregnancy. Patients who received methotrexate were divided into two groups: Those with and those without surgery after methotrexate use. We compared the characteristics of these groups and calculated the methotrexate success rate. RESULTS: We identified 53,653 patients with EP. The proportion of patients undergoing surgery increased from 79% in 2010 to 83% in 2020, whereas the proportion of methotrexate therapy decreased from 8.1% in 2010 to 5.1% in 2020. Regarding methotrexate use for the site of the pregnancy, there was a significant downward trend in methotrexate therapy for tubal pregnancies. Notably, the methotrexate success rate was 84% during the study period. CONCLUSIONS: Surgery showed an increasing tendency over time, whereas methotrexate therapy showed a decreasing tendency for EP treatment in Japan. The efficacy of methotrexate in Japan was comparable to that observed in other countries.


Treatment for ectopic pregnancy includes surgical and non-surgical management. Medical treatment can be as effective as surgery in cases that meet certain criteria. Methotrexate, which is commonly employed as a medical treatment, is widely used in many countries outside Japan. However, reports on methotrexate therapy for ectopic pregnancy in Japan are limited, and the actual status of its use remains unknown. We investigated the treatment trends for ectopic pregnancy in Japan using nationwide inpatient data. The results demonstrated that surgeries increased from 79% in 2010 to 83% in 2020, while methotrexate therapy declined from 8.1% to 5.1%. Methotrexate therapy demonstrated an 84% success rate. Unlike many other countries, surgery became more prevalent while methotrexate therapy decreased for inpatients with ectopic pregnancy in Japan. The success rate of methotrexate in Japan was comparable to that in other countries. Thus, Japanese healthcare providers should consider using methotrexate therapy for appropriate cases and carefully choose the best treatment for each patient after discussing the treatment options with patients.

RÉSUMÉ

Haemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory condition that can be either familial or acquired and, if untreated, frequently results in multiorgan failure and death. Treatment of HLH typically requires a combination of glucocorticoids and cytotoxic chemotherapy. We describe the case of a woman who presented with signs and symptoms concerning for HLH who was later found to have a primary central nervous system (CNS) diffuse large B-cell lymphoma. Her HLH symptoms were successfully treated with high doses of dexamethasone, and her primary CNS lymphoma was treated with high-dose methotrexate and rituximab. This is a rare case of HLH secondary to primary CNS lymphoma where HLH was controlled with steroids alone and did not require the use of an etoposide-based regimen or cyclophosphamide, doxorubicin, vincristine and prednisone.

RÉSUMÉ

BACKGROUND: Central nervous system involvement in chronic lymphocytic leukemia rarely occurs, and there is no standard therapy for central nervous system involvement in chronic lymphocytic leukemia. This article aims to analyze the diagnosis and treatment of central nervous system involvement in chronic lymphocytic leukemia. CASE PRESENTATION: It reports two cases of central nervous system involvement in chronic lymphocytic leukemia describing the clinical course, therapy, and prognosis. Case 1 is a 67-year-old Asian male patient, he experienced complications with central nervous system involvement after developing resistance to ibrutinib, bendamustine, and rituximab (BR) chemotherapies. The central nervous system lesion was controlled with high-dose methotrexate combined with pomalidomide, but Richter transformation occurred several months later. Case 2 is a 62-year-old Asian female patient, she had central nervous system involvement at initial diagnosis, and bone marrow and central nervous system lesions were controlled by ibrutinib therapy. CONCLUSION: Central nervous system involvement in chronic lymphocytic leukemia is rare and can be diagnosed on the basis of clinical features, cerebrospinal fluid testing, and radiographic evaluation. Ibrutinib, pomalidomide, and other drugs that can cross the blood-brain barrier may be effective for treating central nervous system involvement in chronic lymphocytic leukemia.

RÉSUMÉ

STUDY OBJECTIVE: Cesarean scar pregnancy (CSP) is a type of ectopic pregnancy associated with severe complications, including significant hemorrhage, the potential need for hysterectomy, and life-threatening risks. Currently, two classification methods exist for CSP: Vial (type Ia and IIa) and Chinese Expert's Consensus (type Ib, type IIb, and type IIIb). However, these methods have limitations in guiding the selection of appropriate treatment plans for CSP. The purpose of this study was to systematically evaluate the effectiveness of various treatments for CSP within our clinic. METHOD: Our study included 906 patients with CSP from January 2013 to December 2018. The chi-squared test and logistic analysis were used to compare the clinical characteristics. The median and interquartile range (IQR) was calculated. We also analyzed whether preoperative application of methotrexate (MTX) could improve surgical outcomes and the relevant characteristics of misdiagnosed CSP patients. RESULTS: There was a significant difference in gestational age, gestational sac diameter, gestational sac width, gestational sac area, remnant myometrial thickness, vaginal bleeding and preoperative hemoglobin levels (p < 0.001) but not in the incidence of residual tissue (p = 0.053). The other factors (intraoperative blood loss, hemoglobin decline, first hemoglobin after operation, total hospital stay, hospital stay after operation, transfusion and duration of catheter drain) were significantly different (p < 0.001). For type Ia and type Ib CSP, 39.3% and 40.2% of patients were treated with dilatation and curettage (D&E) under ultrasound, respectively. For type IIa and type IIIb CSP, 29.9% and 62.7% of patients were treated with laparotomy, respectively. There were no differences in surgical methods, residual tissue and reoperation between the MTX and non-MTX groups (p = 0.20), but liver damage, hospital stay and pain perception were more remarkable in the MTX group. It is noteworthy that 14% of the patients were misdiagnosed with an intrauterine pregnancy. The incidence of misdiagnosis in type IIa CSP patients was higher than that in type Ia CSP patients (p < 0.001). CONCLUSION: For type I CSP patients, D&E under ultrasound or D&E under hysteroscopy should be recommended. For type IIIb CSP patients, operative resection should be used. It is currently difficult to choose the appropriate treatment methods for type IIa or type IIb CSP patients.

RÉSUMÉ

PURPOSE: This study examines the risk of severe oral mucositis (SOM) in graft-versus-host disease prophylaxis (GVHD) compared to other agents in hematopoietic cell transplantation patients. METHODS: A comprehensive search of four databases, including PubMed, Embassy, Web of Science, and Scopus, was conducted to identify studies reporting frequency and severity of oral mucositis in association with GVHD prophylactic regimens. RevMan 5.4 was used to perform the meta-analysis. Risk of bias assessment was carried out using the Rob-2 tool for randomized clinical trials (RCTs) and ROBINS-I tool for observational studies. RESULTS: Twenty-five papers, including 11 RCTs and 14 observational studies, met the inclusion criteria. The pooled results from eight RCTs showed a higher risk of SOM in patients receiving MTX or MTX-inclusive GVHD prophylaxis versus non-MTX alternatives (RR = 1.50, 95% CI [1.20, 1.87], I2 = 36%, P = 0.0003). Mycophenolate mofetil (MMF) and post-transplant cyclophosphamide (Pt-Cy) consistently showed lower risk of mucositis than MTX. Folinic acid (FA) rescue and mini-dosing of MTX were associated with reduced oral mucositis severity. CONCLUSION: Patients receiving MTX have a higher SOM risk compared to other approaches to prevent GVHD, which should be considered in patient care. When appropriate, MMF, FA, and a mini-dose of MTX may be an alternative that is associated with less SOM. This work also underlines the scarcity of RCTs on MTX interventions to provide the best evidence-based recommendations.

RÉSUMÉ

BACKGROUND: Pompe disease, a rare autosomal recessive disorder caused by acid alpha-glucosidase deficiency, results in progressive glycogen accumulation and multisystem dysfunction. Enzyme replacement therapy with recombinant human acid alpha-glucosidase is the standard of care; however, some patients develop anti-recombinant human acid alpha-glucosidase antibodies, leading to reduced efficacy. This case report presents two infants with early-onset Pompe disease who developed IgG antibodies to enzyme replacement therapy and were subsequently treated with methotrexate, highlighting the importance of monitoring antibody development and exploring alternative therapeutic approaches. CASE PRESENTATION: Patient 1, a 10-month-old female from Bogota, Colombia, presented with generalized hypotonia, macroglossia, hyporeflexia, and mild left ventricular hypertrophy. Diagnostic tests confirmed early-onset Pompe disease, and enzyme replacement therapy was started at 12 months. Due to a lack of improvement and high anti-recombinant human acid alpha-glucosidase IgG antibody titers (1:1800), methotrexate was started at 18 months. After 8 months of combined therapy, antibody titers were negative and significant improvement in motor function was observed using the Gross Motor Function Measure 88. Patient 2, a 7-year-old female from Bogota, Colombia, was diagnosed with early-onset Pompe disease at 12 months and initiated enzyme replacement therapy. At 5 years of age, she experienced frequent falls and grip strength alterations. Functional tests revealed motor development delay, generalized hypotonia, and positive anti-recombinant human acid alpha-glucosidase IgG antibody titers (6400). Methotrexate was initiated, leading to a reduction in falls and antibody titers (3200) after 6 months, with no adverse events or complications. Motor function improvement was assessed using the Motor Function Measurement 32. CONCLUSIONS: The presented cases highlight the importance of monitoring patients for anti-recombinant human acid alpha-glucosidase antibody development during enzyme replacement therapy and the potential benefit of methotrexate as an immunomodulatory agent in early-onset Pompe disease. Early diagnosis and timely initiation of enzyme replacement therapy, combined with prophylactic immune tolerance induction, may improve clinical outcomes and reduce the development of anti-recombinant human acid alpha-glucosidase antibodies. The cases also highlight the importance of objective motor function assessment tools, such as Gross Motor Function Measure 88 and Motor Function Measurement 32, in assessing treatment response. Further research is needed to optimize treatment regimens, monitor long-term effects, and address the current limitations of enzyme replacement therapy in Pompe disease.

RÉSUMÉ

BACKGROUND: Tubal ectopic pregnancy (EP) is a life-threatening condition, especially if undiagnosed or misdiagnosed, tipically in low income countries and/or where women have limited access to health care. The current management protocol of tubal EP consists of either surgical management, or medical management with methotrexate. Recent studies, while few, have suggested that letrozole, an aromatase inhibitor, may play a role in the medical treatment of tubal EP. OBJECTIVES: To evaluate the effectiveness of letrozole alone in the medical treatment of tubal EP. SEARCH STRATEGY: Electronic databases were searched until 31 December 2023. SELECTION CRITERIA: Retrospective or prospective studies reporting the treatment of tubal EP with letrozole alone were considered eligible for inclusion. DATA COLLECTION AND ANALYSIS: Pooled results were expressed as OR with 95 %CI. Heterogeneity was assessed using Higgins I2. Subgroup analysis was performed to compare outcomes according to time after intervention. Subgroup differences were checked through χ2 test. RESULTS: A total of 152 patients were included. Seventy-nine patients (51.97 %) were treated with letrozole, 39 patients (16.54 %) with methotrexate, and 34 patients (31.49 %) underwent surgical treatment. Pooled data analysis supports the consistency of the effect of letrozole in reducing ß-hCG over time at a comparable rate among studies, and that treatment with letrozole is superior to surgery and has the same efficacy as methotrexate. However, all the included studies were judged at high risk of bias in terms of study design, sample representativeness, and sampling technique. Furthermore, short and long term side effects were not reported in any of the included studies. CONCLUSIONS: Letrozole is a promising alternative to methotrexate and surgical therapy in the treatment of tubal EP. Although this meta-analysis suggests efficacy and low hazard of the drug and encourages its application, the data available today remain extremely sparse, which weakens any claims that can be made, and is not sufficient to assert that letrozole is safe and effective in the treatment of EPs. There is an absolute need for randomized studies with accurate patient selection, fixed doses, large sample sizes, and reporting of short- and long-term side effects to refute or confirm this assumption.

RÉSUMÉ

We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

RÉSUMÉ

BACKGROUND: Choriocarcinoma is a highly malignant pregnancy-related trophoblastic neoplasm, characterized by early metastasis to the lungs. Therefore, patients may manifest nongynecological symptoms owing to distant metastases. The incidence of choriocarcinoma after a term pregnancy is really rare (1/160,000 pregnancies). CASE PRESENTATION: We report a case of a 20-year-old Iranian woman, gravida 2 para 1 live 1 abortion 1, who was referred to our gynecology department with sudden onset dyspnea and pain in the left hemithorax the day after her labor. The index pregnancy was without any complications. After the initial workup, the elevation of ß-human chorionic gonadotropin (HCG) levels (> 1,000,000) along with the identification of clinical (vaginal lesions) and radiological evidence of distant metastases (bilateral pulmonary nodes) directed us toward pulmonary metastatic choriocarcinoma diagnosis. After the oncology consult, the etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine chemotherapy regimen was started for the patient. She responded well to the treatment and is currently continuing her chemotherapy process. CONCLUSION: The prognosis of choriocarcinoma is very good if the treatment is started on time. We suggest that clinicians should consider gestational trophoblastic neoplasia in their differential diagnosis of the post-natal period complications, especially after a term and nonmolar pregnancy.

RÉSUMÉ

Nanomaterials have been extensively exploited in tumor treatment, leading to numerous innovative strategies for cancer therapy. While nanomedicines present immense potential, their application in cancer therapy is characterized by significant complexity and unpredictability, especially regarding biocompatibility and anticancer efficiency. These considerations underscore the essential need for the development of ex vivo research models, which provide invaluable insights and understanding into the biosafety and efficacy of nanomedicines in oncology. Fortunately, the emergence of organoid technology offers a novel approach to the preclinical evaluation of the anticancer efficacy of nanomedicines in vitro. Hence, in this study, we constructed intestine and hepatocyte organoid models (Intestine-orgs and Hep-orgs) for assessing intestinal and hepatic toxicity at the microtissue level. We utilized three typical metal-organic frameworks (MOFs), ZIF-8, ZIF-67, and MIL-125, as nanomedicines to further detect their interactions with organoids. Subsequently, the MIL-125 with biocompatibility loaded methotrexate (MTX), forming the nanomedicine (MIL-125-PEG-MTX), indicated a high loading efficiency (82%) and a well-release capability in an acid microenvironment. More importantly, the anticancer effect of the nanomedicine was investigated using an in vitro patient-derived organoids (PDOs) model, achieving inhibition rates of 48% and 78% for PDO-1 and PDO-2, respectively, demonstrating that PDOs could predict clinical response and facilitate prospective therapeutic selection. These achievements presented great potential for organoid-based ex vivo models for nano theragnostic evaluation in biosafety and function.

RÉSUMÉ

Psoriasis might bring about an increased risk of liver diseases like nonalcoholic fatty liver disease and fibrosis. The impact of methotrexate on liver function is still a cause for concern, because of the studies suggesting an increased risk of liver damage and others finding no association. The focus of this study was the liver functions in psoriatic patients investigating the impact of long-term use of methotrexate on liver in psoriasis. A retrospective investigation including 140 patients with psoriasis receiving methotrexate treatment for at least 6 months and a control group consisted of 105 healthy ones was conducted. Liver function tests (AST, ALT, PLT) were assessed, and the association of baseline PASI with FIB-4 and APRI values was investigated. Additionally, FIB-4 and APRI values at baseline, 3rd, and 6th months of methotrexate treatment for psoriasis were compared. Compared with the controls, psoriatic patients exhibited significantly higher FIB-4 scores (p = 0.004). A moderate and significant correlation was observed between baseline PASI score and baseline FIB-4 score in psoriatic patients (p < 0.001, rho = 0.626). Long-term methotrexate use had no effect on APRI or FIB-4 (p = 0.104 and p = 0.475, respectively). Psoriatic patients face an elevated risk of liver fibrosis. Long-term methotrexate use does not adversely affect liver function in psoriatic patients. Noninvasive tools like APRI and FIB-4 scores can be employed to evaluate the risk of liver disease in these patients.

RÉSUMÉ

OBJECTIVES: Despite a high response rate at the first evaluation during induction chemotherapy, the risk of early relapse remains high and unpredictable in primary CNS lymphomas (PCSNLs). We aimed to assess the prognostic value of early IL-10 levels in CSF (e-IL-10) after 2 months of induction chemotherapy. METHODS: We retrospectively selected from the LOC (Lymphomes Oculo-Cérébraux) network database patients with PCSNLs who had complete or partial response at the 2-month evaluation of a high-dose methotrexate-based first-line chemotherapy for whom e-IL-10 was available. RESULTS: Thirty patients (median age: 62 years, brain involvement in 30/30, CSF involvement in 10/30, median baseline CSF IL-10: 27.5 pg/mL) met the selection criteria. e-IL-10 was undetectable in 22 patients and detectable in 8 patients. At the end of induction treatment, 7 of 8 and 4 of 22 of the patients with detectable and undetectable e-IL-10 had experienced progressive disease, respectively (p = 0.001, OR: 26.8, 95% CI 2-1,478). The median progression-free survival times were 5.8 months (95% CI 2.8-8.8) and 28.7 months (95% CI 13.4-43.9) in the groups with detectable and undetectable e-IL-10, respectively (p < 0.001). DISCUSSION: Our results suggest that despite an objective response, the persistence of detectable e-IL-10 is associated with a high risk of early relapse in PCNSL. A closer follow-up of such patients is warranted.
