摘要
Introducción: el metotrexato se usa ampliamente para el tratamiento de una variedad de enfermedades neoplásicas y autoinmunes. Sin embargo, como todo fármaco, su eficacia viene marcada por cierto grado de toxicidad debido a la farmacocinética del medicamento. El metotrexato se creó como un fármaco anticancerígeno; sin embargo, se ha convertido en el tratamiento de elección contra la artritis reumatoide. Principalmente, el metotrexato causa inflamación de las mucosas epiteliales. La mayoría de los efectos secundarios del metotrexato se pueden detectar de forma temprana y son reversibles. La mucositis del tracto alimentario es el principal efecto secundario de la quimioterapia contra el cáncer. Se le conoce colectivamente como lesión de la mucosa inducida por quimioterapia, afecta todo el canal alimentario desde la boca hasta el ano, ocasionando la mucositis oral y la mucositis intestinal. Material y métodos: se buscaron casos clínicos en los que se reporte mucositis causada por metotrexato en tratamiento de artritis reumatoide. Se empleó un diagrama de flujo, PRISMA modificado para la búsqueda de artículos. Finalmente, se cotejó que los casos clínicos cumplieran con los fundamentos de la CARE guide, para manejar una correcta estructura y bajo riesgo a sesgo. Conclusiones: una correcta anamnesis y exploración clínica oral es lo más importante de la medicina oral. Es relevante indagar sobre las enfermedades que presentan los pacientes, así como la historia de medicamentos que se administren, especialmente en pacientes mayores, con mayores padecimientos de enfermedades sistémicas (AU)
Introduction: methotrexate is widely used for the treatment of a variety of neoplastic and autoimmune diseases. However, like all drugs its efficacy is marked by a certain degree of toxicity due to the pharmacokinetics of the drug. Methotrexate was developed as an anticancer drug, however, it has become the treatment of choice for rheumatoid arthritis. Methotrexate primarily causes inflammation of the epithelial mucous membranes. Most of the side effects of methotrexate can be detected early and are reversible. Mucositis of the alimentary tract is the main side effect of cancer chemotherapy. It is collectively known as chemotherapy-induced mucosal injury, affecting the entire alimentary canal from the mouth to the anus, where oral mucositis and intestinal mucositis are both common. Material and methods: we searched for clinical cases reporting mucositis caused by methotrexate in the treatment of rheumatoid arthritis, using a modified PRISMA flowchart to search for articles. Finally, the clinical cases were checked for compliance with the fundamentals of the CARE guide, in order to manage a correct approach to oral medicine. It is important to inquire about the diseases the patients present, as well as the history of medications administered, especially in older patients, with more systemic disease conditions, structure, and low risk of bias. Conclusion: a correct anamnesis and oral clinical examination is the most important aspect of oral medicine. It is important to inquire about the diseases that the patients present, as well as the history of medications that are administered, especially in older patients with major systemic diseases (AU)

Abstract Background: Methotrexate (MTX) is an alternative treatment for patients with moderate/severe atopic dermatitis (AD). Objective: The authors evaluated the effect of MTX on the cutaneous expression of cytokines and chemokines that are involved in the inflammatory response in adult AD patients who received treatment with methotrexate for 24 weeks. Methods: The authors conducted a prospective single-institution cohort study with 12 adults with moderate/severe AD who received oral MTX (15 mg/wk for 24 wks) and 10 non-atopic matched controls. The comparison was made of skin biopsies of lesional and non-lesional skin, pre- and post MTX treatment. The authors analyzed mean epidermal thickness and expression of IL-31, IL-31RA, OSMR, TSLP, Ki67, IL-4 mRNA, IL-6, IL-10, TNF-α, IFN-γ, TARC, and CCL-22. Results: There was a reduction in mean epidermal thickness (p = 0.021), an increase in IL-31RA expression (immunohistochemistry) in the epidermis (p = 0.016) and a decrease in IL-31 gene expression (p = 0.019) on lesional AD skin post-MTX treatment. No significant changes in the cutaneous expression of the other evaluated markers were identified. Study limitations: Small sample size and limited length of follow-up. Conclusions: Treatment with MTX in adults with moderate/severe AD reduced epidermal hyperplasia and changed the cutaneous expression of inflammatory cytokines and receptors that are mainly related to pruritus, including IL-31 and IL-31RA.

Objective:To explore the relationship between reduced folate carrier 1(RFC1) gene polymorphism a curative effect, plasma concentration and adverse reaction of methotrexate (MTX) in patients with rheumatoid arthritis (RA).Methods:A total of 268 RA patients with 82 males and 186 females, aged (52.47±10.29) years, who received MTX treatment in the First People's Hospital of Shangqiu, from Jan 20, 2018 to Jan 20, 2021 were collected by case-control study. The genotype of RFC1 G80A locus were detected. The plasma concentration of MTX were detected after initial administration for 48 hours. The curative effect and adverse reactions were observed and counted after treatment for 6 months. The differences of RFC1 G80A genotype among different groups were compared. Collinearity diagnosis and logistic regression were used to analyze the influencing factors of MTX efficacy and plasma concentration. The incidences of adverse reactions among patients with different genotype were compared by Chi-square test.Results:The distribution of RFC1 G80A genotype (GG/GA/AA) and gene frequency (G/A) showed statistically significant differences between the effective group and the ineffective group (χ 2=6.583, P=0.037; χ 2=6.249, P=0.012), and the effective rate of AA type [59.26% (32/54)] was higher than that of GG type [36.49% (27/74)] (χ 2=6.516, P=0.011). Logistic regression analysis showed that the OR (95% CI) value of MTX response rate in AA genotype patients versus GG genotype patients was 2.491(1.206-5.144). The 48 hour plasma drug concentration of AA type patients was 1.15 (0.75, 1.35) μmol/L. Compared with GG type [0.74 (0.61, 1.18) μmol/L] and GA type [0.84 (0.69, 0.99) μmol/L], the difference was statistically significant(χ 2=7.152, P=0.028). Logistic regression analysis showed that the probability of high 48 hour plasma drug concentration in patients with AA type was approximately 2.583 (1.238-5.390) times higher than that in patients with GG type. There was a statistically significant difference in the incidence of liver function injury among three different genotypes (GG/GA/AA) (χ 2=12.606, P=0.002). Conclusion:RFC1 G80A locus polymorphism can affect the MTX efficacy, blood drug concentration and liver function damage in RA patients. AA type patients have better efficacy and higher blood drug concentration compared to GG type patients, but the rate of liver function damage is also higher.

OBJECTIVE To explore the effects of 5，10-methylenetetetrahydrofolate reductase （MTHFR） gene polymorphism on the adverse reactions in patients with osteosarcoma after the first high-dose methotrexate （HD-MTX） treatment. METHODS A prospective study was conducted to include 53 patients with osteosarcoma treated with HD-MTX at the first admission in General Hospital of Eastern Theater Command. The dose of MTX was evaluated according to the polymorphism of rs1801133 in the METHFR gene and demographic factors， then whole pharmaceutical monitoring was conducted. The data on liver toxicity， renal toxicity， hematological toxicity， and gastrointestinal reaction were collected after the first chemotherapy cycle. Single factor analysis and binary Logistic regression analysis were used to analyze the correlation between MTX dose， 24 h blood drug concentration， and rs1801133 locus genotype with four adverse reactions. RESULTS The MTX dosage in patients with CC wild type was significantly higher than that in TT mutant type （7.97 g/m2 vs. 6.98 g/m2， P＝0.030）， but this difference did not affect the 0 h and 24 h blood drug concentrations of MTX. The above four adverse reactions were not related to the dose of MTX. The results of binary Logistic regression analysis showed that carrying one T allele increased the risk of developing hematological toxicity by 4.13 times（95% confidence interval：1.35-12.62，P＝0.013）. When 24 h plasma concentration threshold of MTX was set to 2.65 µmol/L， the sensitivity and specificity of predicting liver function damage were 53.33% and 86.96%， respectively； when the threshold was set to 7.28 μmol/L， the sensitivity and specificity of predicting renal damage were 100% and 81.63%. CONCLUSIONS The polymorphism of the rs1801133 in the MTHFR gene is associated with hematological toxicity of MTX. Patients who take HD-MTX for the first time and carry the T allele have a high risk of hematological toxicity. The 24 h plasma concentration of MTX is related to liver toxicity and renal toxicity. In addition， monitoring the 24 h blood drug concentration can predict liver and renal toxicity， and take early intervention.

Abstract The present study aimed to investigate the beneficial of prepared black rice anthocyanins nano-composite (An-AgNps) against hepatotoxicity induced by methotrexate (MTX) in rats. Anthocyanins nano-composite was prepared by silver as the metallic ion reduction and were characterized by IR and SEM. The rats in our experiment were divided into five groups. Serum lipid profile, serum transaminases (ALT and AST), ALP, LDH, TBA, GSH and SOD were examined. The results show that SEM of An-AgNps has average particle size from 70 to 130nm. In the group treated with MTX; TC, TG, LDL-c, ALT, AST, ALP, LDH and TBA levels were significantly (P0.05) increased than NC, while, HDL-c, SOD and GSH levels were significantly (P0.05) decreased. On the other hand, An-AgNps + MTX treated groups were reversed the levels of all biomarkers similar to NC. In conclusion, the results show that An-AgNps has a protective effect on MTX-induced hepatotoxicity and oxidative stress.

La enfermedad trofoblástica gestacional es definida como un grupo heterogéneo de lesiones, las cuales surgen a partir del epitelio trofoblástico de la placenta luego de una fertilización anormal. Se presenta el caso de una paciente de 35 años de edad, con diagnóstico de neoplasia trofoblástica gestacional posmolar en etapa I, que se detectó tras estudios imagenológicos de seguimiento y determinación de la hormona gonadotropina coriónica humana, para lo cual llevó tratamiento con quimioterapia y terapéutica de mantenimiento con metotrexato por 5 días o metotrexato/ácido folínico por 8 días, hasta la normalización de la gonadotropina coriónica humana. Lo más relevante es que, aunque estos tumores abarcan menos del 1 % de los tumores ginecológicos, representan una amenaza para la vida de las mujeres en edad reproductiva.
Gestational trophoblastic disease is defined as a heterogeneous group of lesions, which arise from the trophoblastic epithelium of the placenta after abnormal fertilization. The case of a 35-year-old female patient is presented with a diagnosis of posmolar gestational trophoblastic neoplasia in stage I, which was detected after follow-up imaging studies and determination of human chorionic gonadotropin, for which she underwent chemotherapy treatment and maintenance therapy with methotrexate for 5 days or methotrexate/folinic acid for 8 days, until normalization of human chorionic gonadotropin The most relevant thing is that, although these tumors comprise less than 1% of gynecological tumors, they represent a threat to the life of women of reproductive age.
摘要
ABSTRACT Purpose: To report the clinical findings, treatments, and outcomes in a series of patients with vitreous metastasis from cutaneous melanoma. Methods: This single-center, retrospective, interventional case series included patients with biopsy-confirmed vitreous metastasis from cutaneous melanoma diagnosed between 1997 and 2020. Standard 23- or 25-gauge pars plana vitrectomy was performed for diagnostic sampling. Sclerotomies were treated with double or triple freeze-thaw cryotherapy. Perioperative intravitreal injections of melphalan (32 µg/0.075 mL) were administered, when indicated. Visual acuity, intraocular pressure, and systemic and ocular treatment responses were reported. Results: Five eyes of five patients with unilateral vitreous metastasis from cutaneous melanoma were identified. The median age at diagnosis was 84 (range, 37-88) years. The median follow-up after ophthalmic diagnosis was 28 (8.5-36) months; one patient did not have a follow-up. The initial visual acuity ranged from 20/30 to hand motions. Baseline clinical findings included pigmented or non-pigmented cellular infiltration of the vitreous (5/5), anterior segment (4/5), and retina (3/5). Four patients had secondary glaucoma. Systemic therapy included checkpoint inhibitor immunotherapy (n=3, all with partial/complete response), systemic chemotherapy (n=2), surgical resection (n=3), and radiation (n=2). The median time from primary diagnosis to vitreous metastasis was 2 (2-15) years. One patient had an active systemic disease at the time of vitreous metastasis. The final visual acuity ranged from 20/40 to no light perception. Ophthalmic treatment included vitrectomy in all five patients, intravitreal administration of melphalan in three, and intravitreal administration of methotrexate in one. One patient required enucleation, and histopathology revealed extensive invasion by melanoma cells. Conclusions: Vitreous metastasis from cutaneous melanoma can present as a diffuse infiltration of pigmented or non-pigmented cells into the vitreous and may be misdiagnosed as uveitis. Diagnostic pars plana vitrectomy and periodic intravitreal chemotherapy may be indicated.
RESUMO Objetivo: Descrever os achados clínicos, tratamentos, e desfechos em uma série de pacientes com me tástases vítreas de melanoma cutâneo. Métodos: Série retrospectiva de casos de único centro com intervenção. Pacientes incluídos tiveram seu diagnóstico de MVMC confirmado por biópsia entre 1997 e 2020. Vitrectomia via pars plana com 23 ou 25 gauge foram realizadas para obter espécimens. Esclerotomias foram tratadas com crioterapia em duplo ou triplo congelamento. Injeção intravítrea perioperatória de melfalano (32 ug/0,075 mL) foi administrada quando necessário. Foram relatados acuidade visual, pressão intraocular, resposta terapêutica sistêmica e ocular. Resultados: Cinco olhos de 5 pacientes com metástases vítreas de melanoma cutâneo unilateral foram identificados. Idade média de diagnóstico foi 84 anos (variando de 37-88). Seguimento médio após diagnóstico oftalmológico foi 28 (8,5-36) meses; 1 paciente não teve acompanhamento. Acuidade visual inicial variou de 20/30 a movimentos de mão. Achados clínicos iniciais incluíram infiltração de células pigmentadas e não-pigmentadas no vítreo (5/5), segmento anterior (4/5), e retina (3/5). Quatro pacientes tiveram glaucoma secundário. Tratamento sistêmico incluiu imunoterapia com inibidores da via de sinalização (3 - todos com resposta parcial/completa), quimioterapia sistêmica (2), ressecção cirúrgica (3), e irradiação (2). Intervalo médio entre diagnóstico primário e metástases vítreas foi 2 (2-15) anos. Um paciente teve doença sistêmica ativa simultânea as metástases vítreas. Acuidade visual final variou entre 20/40 e SPL. Tratamento oftalmológico incluiu vitrectomia nos 5 pacientes, melfalano intravítreo em 3 e metotrexato intravítreo em 1. Um paciente precisou de enucleação. A histopatologia revelou invasão celular extensa de melanoma. Conclusões: Metástases vítreas de melanoma cutâneo pode se manifestar como uma infiltração difusa de células pigmentadas e não-pigmentadas no vítreo e erroneamente diagnosticada como uveites. Vitrectomia diagnóstica e quimioterapia intravítrea periódica podem estar indicadas.

ABSTRACT Introduction: The diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL) and, despite all the progress in this field, central nervous system infiltration (CNSi) still occurs at an incidence of 2-10%. The objective of the present study was to evaluate the Central Nervous System International Prognostic Index (CNS-IPI) score in daily practice regarding the reproducibility in a heterogeneous cohort apart from a clinical trial. Methods: Primary DLBCL patients were eligible for this study, between January 2007 and January 2017. All patients were treated with rituximab-based chemotherapy, mostly R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone). The CNSi was diagnosed by liquor (positive cytology and/or immunophenotype), computerized tomography, magnetic resonance image and/or fluorodeoxy-glucose-positron emission tomography, requested only in symptomatic patients when the CNSi was clinically suspected. The CNS-IPI was assessed by graphical comparison and calibration. Results: After applying the inclusion/exclusion criteria, 322 patients were available for the analysis. The median follow-up was 60 months and the median age was 58 years. Seven patients experienced CNSi, characterizing an incidence of 2.17% (7/322). Comparing groups of patients with and without CNSi, we observed that the lactate dehydrogenase (LDH), number of extranodal sites, IPI, kidney/adrenal and absence of complete response were statistically different. The CNS-IPI model stratified patients in a three-risk group model as low-, intermediate- and high-risk. In our cohort, using the same stratification, we obtained an equivalent the 2-year rate of CNS relapse of 0.0%, 0.8% and 13.8%, respectively. Conclusion: Our study reinforces the reproducibility of the CNS-IPI, specifically apart from clinical trials, and suggests the CNS-IPI score as a tool to guide therapy.

Introducción: El embarazo ectópico intersticial es una forma de presentación poco frecuente, con una incidencia del 2-4% de los embarazos ectópicos; sin embargo, a pesar de su baja incidencia la mortalidad es cinco veces mayor, impactando en las cifras de mortalidad materna y representando en torno al 10-15% de los casos. Objetivo: Presentar un caso de embarazo ectópico intersticial, cuya ocurrencia es poco frecuente, así como el abordaje satisfactorio del manejo médico con mifepristona y metotrexato. Caso clínico: Mujer de 28 años con antecedente de resección tubárica por quiste paraovárico derecho, quien acudió a urgencias por hallazgo en ecografía obstétrica de sospecha de embarazo intersticial izquierdo y se le administró manejo farmacológico con dosis de metotrexato y mifepristona, con éxito. Conclusiones: El manejo médico con metotrexato y mifepristona para el embarazo ectópico intersticial parece ser una elección eficaz en los casos con estabilidad hemodinámica y deseo de conservación de la fertilidad.
Background: Interstitial ectopic pregnancy represents a rare form of presentation, with an incidence of 2-4% of all ectopic pregnancies. However, despite its low incidence, it is associated with a five-fold increase in mortality, significantly impacting maternal mortality rates, accounting for approximately 10-15% of cases. Objective: To present a case of interstitial ectopic pregnancy, which is a rare occurrence, as well as the successful medical management approach with mifepristone and methotrexate. Case report: A 28-year-old women with a history of right paraovarian cyst tubal resection presented to the emergency department due to suspected left interstitial pregnancy identified on obstetric ultrasound. The patient was successfully managed with pharmacological treatment using doses of methotrexate and mifepristone. Conclusions: Medical management with methotrexate and mifepristone for interstitial ectopic pregnancy appears to be an effective choice in cases with hemodynamic stability and a desire for fertility preservation.

Objetivos: Describir las características clínicas y el tratamiento del embarazo ectópico implantado en la cicatriz de cesárea, así como las complicaciones y el pronóstico obstétrico. Materiales y métodos: Estudio de cohorte retrospectivo de gestantes con diagnóstico de embarazo ectópico implantado en la cicatriz de cesárea según los criterios de la Sociedad de Medicina Materno-Fetal, atendidas entre enero de 2018 y marzo de 2022 en dos instituciones de alta complejidad, pertenecientes a la seguridad social, ubicadas en Lima, Perú. Se hizo un muestreo consecutivo. Se midieron variables sociodemográficas y clínicas de ingreso, diagnóstico, tipo de tratamiento, complicaciones y pronóstico obstétrico. Se hace un análisis descriptivo. Resultados: Se incluyeron 17 pacientes, de 29.919 partos. De estas, el 41,2 % recibió tratamiento médico y el resto recibió tratamiento quirúrgico. Se realizó un manejo local exitoso con metotrexato en el saco gestacional en dos pacientes con ectópico tipo 2. Cuatro de las pacientes requirieron histerectomía total. Seis pacientes experimentaron una gestación después del tratamiento, y 4 de ellas culminaron el embarazo con una madre y un neonato saludables. Conclusiones: El embarazo ectópico implantado en la cicatriz de una cesárea es una entidad poco frecuente, para la cual se cuenta con alternativas de manejo médico y quirúrgico con aparentes buenos resultados. Se requieren más estudios con mayor calidad metodológica de asignación aleatoria que ayuden a caracterizar la seguridad y la efectividad de las diferentes alternativas terapéuticas para las mujeres con sospecha de esta patología.
Objectives: To describe the clinical characteristics and treatment of ectopic pregnancy arising in the cesarean section scar, as well as its complications and obstetric prognosis. Material and methods: Retrospective cohort study of pregnant women with the diagnosis of a scar pregnancy in accordance with Maternal-Fetal Medicine Society criteria, seen between January 2018 and March 2022 in two high complexity institutions of the social security system, located in Lima, Peru. Consecutive sampling was used. Baseline sociodemographic and clinical variables were measured, including diagnosis, type of treatment, complications and obstetric prognosis. A descriptive analysis was performed. Results: Out of 29,919 deliveries, 17 patients were included. Of these, 41.2 % received medical management and the rest were treated surgically. Successful management with intra-gestational sac methotrexate was performed in two patients with ectopic pregnancy type 2. Four patients required total hysterectomy. Six patients became pregnant after the treatment and 4 completed their pregnancy with healthy mother and neonate pairs. Conclusions: Ectopic pregnancy implanted in a cesarean section scar is an infrequent occurrence for which medical and surgical management options are available with apparently good outcomes. Further studies of better methodological quality and random assignment are needed in order to help characterize the safety and effectiveness of the various therapeutic options for women with suspected scar pregnancy.

A 36-year-old Asian Indian male presented with redness and pain in his right eye of 1 week duration. He was diagnosed to have right acute anterior uveitis and had a history of being admitted at a local hospital for dengue hepatitis a month earlier. He had been on adalimumab 40 mg three weekly once and oral methotrexate 20 mg/week for human leucocyte antigen (HLA) B27 spondyloarthropathy and recurrent anterior uveitis. Our patient had re-activation of his anterior chamber inflammation on three distinct occasions: first, 3 weeks following recovery from coronavirus disease 2019 (COVID-19), the second after the second dose of COVID-19 vaccination, and the third after recovery from dengue fever-associated hepatitis. We propose molecular mimicry and bystander activation as the postulated mechanisms for the re-activation of his anterior uveitis. In conclusion, patients with auto-immune diseases can have recurrent ocular inflammation following COVID-19 or its vaccination or dengue fever as seen in our patient. The anterior uveitis is usually mild and responds to topical steroids. Additional immuno-suppression may not be needed. Mild ocular inflammation following vaccination should not deter individuals from getting COVID-19 vaccination.
摘要
Background: Osteosarcoma is a malignant cancer that effect bone and metastasizing to many vital organs such as lungs. There are many available drugs to treat the disease including tamoxifen, methotrexate (MTX), and cisplatin which have their own side effects and hurdles to become drugs of choice for the disease. On the other hand, introduction of herbal drugs as chemotherapeutic agents opened up new arena to potentiate the existing treatment by exhibiting synergy. Piperine (PPN) is widely used drug as anti-cancer agent as well as it has anti-inflammatory, analgesic properties, and also used in the treatment of abdominal pains, tuberculosis, arthritis, and respiratory illness. Aims and Objective: Thus, this study was designed to investigate the synergistic inhibitory potential of PPN and MTX on the MG63 osteosarcoma cell lines in vitro. Materials and Methods: The cell lines were cultured on DMEM medium and investigated for cytotoxicity of the drugs using MTT assay at 540 nm in UV. Three groups of cell lines administered with PPN, MTX, and PPN+MTX (1:1) in various concentrations and IC50 values were calculated based on the % cell viability graphs. Results: Results showed that the IC50 of PPN was 38.65, MTX was 123.98, and PPN+MTX was 15.13 proving the significant synergistic cytotoxic effect of PPN and MTX in inhibiting the proliferation of MG63 cell lines. Conclusion: Further research needs to be conducted in this field to elucidate the synergistic pathways in which PPN has shown a better anti-osteosarcoma effect when combined with MTX.

Background: Palmoplantar psoriasis is a chronic debilitating condition which significantly impairs quality of life. Objectives: To assess the efficacy and safety of the combination of apremilast and methotrexate compared with methotrexate monotherapy in the treatment of palmoplantar psoriasis. Also, to study the impact on treatment on the Dermatology Life Quality Index and Palmoplantar Quality of Life Index. Methods: A total of 64 patients were randomised to two groups in a 1:1 ratio - Group A received both methotrexate and apremilast in combination, while Group B received only methotrexate, for 16 weeks. The primary endpoints were the mean score of Modified Palmoplantar Psoriasis Area and Severity Index at week 16, the proportion of patients achieving modified palmoplantar psoriasis area severity index-75 and/or Palmoplantar Psoriasis Physician Global Assessment score 0/1 at week 16. Results: A significantly higher proportion of patients in Group A achieved Modified Palmoplantar Psoriasis Area and Severity Index-75 at week 16 (43% in Group A vs 30% in Group B). The Modified Palmoplantar Psoriasis Area and Severity Index score was significantly lower in the combination group at week 16 (4.03 ± 2.05 in Group A and 5.89 ± 2.31 in Group B, P-value = 0.002). About 80% of patients in the combination group with baseline Palmoplantar Psoriasis Physician Global Assessment ?3 achieved Palmoplantar Psoriasis Physician Global Assessment 0/1 compared to 60% in Group B. The combination group showed a significantly higher reduction in Dermatology Life Quality Index and Palmoplantar Quality of Life Index scores compared to the methotrexate alone group (P-value = 0.025). No notable adverse events were observed. Limitation: The limitations of the study were single blinding, small sample size and a lack of longer follow up to assess the rate of relapse. We did not account for attrition during sample size calculation. Also, due to the paucity of data regarding the use of apremilast in palmoplantar psoriasis, definitive comparisons could not be made with previous studies. Conclusion: The combination of apremilast and methotrexate has superior efficacy and a similar safety profile as compared to methotrexate monotherapy for the treatment of moderate to severe palmoplantar psoriasis
摘要
El metotrexato es un fármaco análogo del ácido fólico ampliamente utilizado en el tratamiento de enfermedades autoinmunes, leucemias y linfomas. Su uso puede ocasionar la aparición de múltiples efectos adversos entre los que se encuentran aquellos relacionados con la presencia de toxicidad neurológica, que puede presentarse de forma aguda, subaguda o crónica. La neurotoxicidad subaguda es aquella que ocurre típicamente entre los 2 y los 14 días posteriores a la administración y puede manifestarse con una amplia gama de síntomas neurológicos. En la mayoría de los casos, no recurre con futuras exposiciones al medicamento. Presentamos tres casos de neurotoxicidad subaguda por metotrexato con manifestaciones clínicas diferentes en pacientes oncohematológicos que se internaron entre los años 2018 y 2020. Dos de ellos presentaron recurrencia frente a la nueva administración del fármaco y todos evidenciaron lesiones en resonancia magnética nuclear.
Methotrexate is a folic acid analogue widely used in the treatment of autoimmune diseases, leukemias, and lymphomas. Methotrexate use may cause multiple adverse effects, including those related to the presence of neurological toxicity, which may be acute, subacute, or chronic. Subacute neurotoxicity typically occurs between 2 and 14 days after administration and may present as a wide range of neurological symptoms. In most cases, it does not recur with future exposures to the drug. Here we describe 3 cases of subacute methotrexate neurotoxicity with different clinical manifestations in patients with oncohematological disease who were hospitalized between 2018 and 2020. Two of them showed recurrence with a new drug administration. Lesions were observed in the magnetic resonance imaging tests of all of them.

Objetivo: Avaliar o índice de sucesso do tratamento da gravidez ectópica com o protocolo de dose única do metotrexato e verificar sua correlação com variáveis clínicas e dados dos exames complementares. Métodos: É um estudo epidemiológico observacional, analítico, retrospectivo, de delineamento transversal. Foi realizado de janeiro de 2014 a agosto de 2020 em um hospital público, de ensino, em nível terciário, do Sul do Brasil. Em 73 casos com diagnóstico de gestação ectópica íntegra, foi utilizado o protocolo de dose única de metotrexato intramuscular, com a dose de 50 mg/m2 de superfície corporal. As variáveis do estudo foram relacionadas ao sucesso do tratamento e abordaram as características clínicas na admissão, dos exames complementares e do tratamento realizado. As variáveis foram comparadas por análise de regressão de Poisson. O nível de significância estabelecido foi de p < 0,05. Resultados: O índice de sucesso foi de 83,6%, e em nove casos foi necessária uma segunda dose da medicação. Nível de ß-hCG inicial superior a 5.000 mUI/mL foi relacionado a menor chance de sucesso (odds ratio ajustado de 0,20 [0,05-0,95]). Tamanho da imagem anexial, presença de líquido livre na cavidade abdominal e demais variáveis estudadas não afetaram a chance de sucesso do tratamento. Conclusão: O protocolo de dose única de metotrexato mostrou-se uma opção válida para o tratamento da gestação ectópica íntegra, notadamente quando o nível de ß-hCG inicial é inferior 5.000 mUI/mL.
Objective: The purpose of the present study is to evaluate the success rate of treatment of ectopic pregnancy with the single-dose methotrexate protocol and to verify its correlation with clinical variables and complementary exam data. Methods: This is a retrospective epidemiological observational analytical cross-sectional study. It was carried out from January 2014 to August 2020 in a tertiary level teaching hospital in southern Brazil. In 73 cases with a diagnosis of intact ectopic pregnancy, the intramuscular methotrexate single-dose protocol was applied with a dose of 50 mg/m2 of body surface. The study variables were related to the success of the treatment and addressed the clinical characteristics on admission, the complementary exams and the treatment performed. The variables were compared by Poisson regression analysis. The level of significance was set at p < 0.05. Results: The success rate was 83.6%, and in nine cases a second dose of the medication was necessary. An initial ß-hCG level greater than 5,000 mIU/mL was related to a lower chance of success (adjusted odds ratio of 0.20 [0.05- 0.95]). The size of the adnexal image, the presence of free fluid in the abdominal cavity and other variables studied did not affect the chance of a successful treatment. Conclusion: The methotrexate single-dose protocol proved to be a valid option for the treatment of intact ectopic pregnancy, notably when the initial ß-hCG level is below 5,000 mIU/mL.

El síndrome SAPHO es una enfermedad autoinflamatoria crónica que engloba una serie de manifestaciones cutáneas y osteoarticulares que incluyen sinovitis, acné, pustulosis, hiperostosis y osteítis. Se presenta el caso de un paciente masculino de 18 años de edad, con antecedente de esclerodermia localizada diagnosticada por biopsia hace 3 años, quien debutó con lesiones cutáneas y osteoarticulares 6 meses después de suspender tratamiento con metotrexate y colchicina, para dicho antecedente. Se reportó una resonancia magnética sugestiva de una sacroileítis con presencia de edema óseo; y la gammagrafía ósea reveló zonas de captación con imagen en cabeza de toro en articulación esternoclavicular, sugiriendo síndrome de SAPHO. Se decidió reincorporar el metotrexate y colchicina, evolucionando satisfactoriamente. No se encontraron reportes similares concomitando estas dos entidades que tienen como punto en común el tratamiento con los mismos fármacos.
SAPHO syndrome is a chronic autoinflammatory disease that encompasses a series of cutaneous and osteoarticular manifestations that include synovitis, acne, pustulosis, hyperostosis, and osteitis. We present the case of an 18-year-old male patient, with a history of localized scleroderma diagnosed by biopsy 3 years ago, who debuted with skin and osteoarticular lesions 6 months after discontinuing treatment with methotrexate and colchicine, for said history. An MRI suggestive of sacroiliitis with the presence of bone edema was reported, and bone scintigraphy revealed uptake areas with a bull's head image in the sternoclavicular joint, suggesting SAPHO syndrome. It was decided to reincorporate methotrexate and colchicine, evolving satisfactorily. No similar reports were found coexisting with these two entities that have treatment with the same drugs as a point in common.
