Effectiveness of methotrexate and leflunomide as corticoid-sparing drugs in patients with polymyalgia rheumatica.

Objectives: The need for glucocorticoid-sparing drugs (GCSD) remains an important issue and is an unmet need in the treatment of polymyalgia rheumatica (PMR). We therefore aimed to assess the effectiveness and safety of methotrexate (MTX) and of leflunomide (LEF) in daily clinical practice in PMR patients from Argentina. Methods: A multicentre and observational study (medical records review) of PMR patients seen between 2007 and 2023, who had at least three months of follow-up after starting a GCSD, either MTX or LEF, was performed. Results are expressed as medians and interquartile ranges [25th-75th (IQR)] for continuous variables and percentages for categorical ones. The two treatment groups were compared using χ2 test for categorical variables, Mann-Whitney U test for continuous variables and the log-rank test for time-to-event data. Crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using logistic regression. In all cases, a p-value <0.05 was considered statistically significant. Results: One-hundred and eighty-six patients (79% female) with a median age of 72 years (IQR, 65-77 years) were included. One-hundred and forty-three patients (77%) were prescribed MTX (15, IQR 10-15) and 43 (23%) LEF (20 mg, fixed dose). Flare-ups (relapses and recurrences) occurred in 13 patients (7%) and were comparable between both groups. Persistent GCSD intake was observed in 145 patients (78%). Glucocorticoid (GC) withdrawal was achieved in 67 of these 145 patients (46%) and this occurred more frequently in the LEF group (P = 0.001). Furthermore, time until prednisone discontinuation was shorter in the LEF-treated patients (4.7 months, IQR 3-20 on LEF versus 31.8 months, IQR 10-82 on MTX, P = 0.000). Remission was found more frequently in the LEF group (P = 0.003). In the multivariate analysis, the probability of remission was higher with LEF therapy (P = 0.010) and this finding persisted in the subgroup analysis who were followed up < 40 months (OR 3.12, 95% CI = 1.30-7.47, P = 0.011). Conclusions: This study demonstrated the clinical effectiveness of LEF and even its superiority in achieving remission when compared with MTX as GCSD in PMR patients. Further research is needed to support these findings.

Risk Factors for Relapse and/or Prolonged Glucocorticoid Therapy in Polymyalgia Rheumatica: Multicenter Study in 185 Patients.

BACKGROUND: In polymyalgia rheumatica (PMR) relapses and long-term GC dependency are common. We assessed risk factors for higher relapse rate and/or prolonged glucocorticoid therapy in PMR patients. METHODS: A multicenter and observational study (chart review) of PMR patients seen between 2006 and 2021 who had at least a 3-month follow-up period after starting GCs was performed. Results were expressed as median and interquartile range 25th-75th or mean ± standard deviation for numerical variables and percentage for categorical ones. Relapse versus nonrelapse groups were compared using Cox proportional analysis. Hazards ratios (HRs) with 95% confidence intervals (CIs) are reported. In all cases, a p value <0.05 was considered to indicate statistical significance. RESULTS: We included 185 patients (69.1% female). The median follow-up time was 17.1 months (interquartile range, 6.8-34.7). Incidence of relapses was 1.2 per 100 persons/month. In univariate analysis, PMR patients with a previous history of dyslipidemia had a lower risk of relapse (HR, 0.55; 95% CI, 0.33-0.94; p = 0.03); high-dose GC (HR, 2.35; 95% CI, 1.42-3.87; p = 0.001) and faster GC dose reduction had higher risk of relapse (HR, 3.04; 95% CI, 1.77-5.21; p = 0.001). In multivariate analysis, a previous history of dyslipidemia had a lower risk of relapse (HR, 0.54; 95% CI, 0.32-0.92; p = 0.023), and high dose of GC (HR, 2.46; 95% CI, 1.49-4.08; p = 0.001) remained the only risk factors for relapse. CONCLUSIONS: Lower doses of corticosteroids and a slow rate of reduction are critical to avoid relapse in PMR. Risk factors for higher relapse rate rely on therapy more than clinical characteristics of the patients at the time of diagnosis of PMR.

Infecciones graves en pacientes con enfermedades autoinmunes tratados con ciclofosfamida / Severe infections in patients with autoimmune diseases treated with cyclophosphamide

Introducción Las infecciones son una de las principales causas de morbimortalidad en los pacientes con enfermedades autoinmunes sistémicas. Los corticoides y los inmunosupresores como la ciclofosfamida (CF) son algunos de los factores que se asocian a esta complicación. El objetivo de este estudio fue determinar el porcentaje de pacientes que presentaron infecciones graves durante el tratamiento con CF y en los 3 meses posteriores. Pacientes y métodos. Se realizó un análisis retrospectivo de 60 pacientes con diferentes enfermedades autoinmunes que recibieron tratamiento con CF. Se valoró el porcentaje de infecciones graves. Resultados. La patología mñas común fue el lupus eritematoso sistémico y la indicación más común fue la glomerulonefritis proliferativa difusa. El 15% de los pacientes presentó un episodio infeccioso. Las infecciones más frecuentes fueron neumonía adquirida en la comunidad en 3 casos y herpes zóster en 2 casos. La dosis acumulada de corticoides fue el único parámetro que se asoció a infecciones 32,8 ± 16,7 vs. 20,1 ± 15,3 p = 0,007. Conclusión. Un seguimiento estricto, la utilización de corticoides en la menor dosis posible y el tratamiento enérgico de los procesos infecciosos permiten un perfil de seguridad aceptable en aquellos pacientes tratados con CF (AU)

Introduction. Infectious diseases are a significant cause of morbidity and mortality in patients with connective tissue diseases. Corticosteroids and immunosuppressive drugs, such as cyclophosphamide (CYC), increases the risk of infections. The objective of this study was to estimate the incidence rates of severe infections in patients who received treatment with CYC. Patients and methods. The records of 60 patients with systemic autoimmune diseases who received treatment with CYC were retrospectively reviewed. We evaluated the rate of severe infections that occurred during CYC therapy and the 3 subsequent months. Results. Systemic lupus erythematosus was the most common disease, and diffuse proliferative glomerulonephritis the most frequent indication. Severe infection occurred in 9 patients (15%). Community acquired pneumonia was the most frequent infection with 3 cases (33%) followed by Herpes Zoster with 2 reports (22%). The cumulative dose of corticosteroid was the only significant risk factor for infection 32.8±16.7 vs. 20.1±15.3 P=.007. Conclusion. The use of lower doses of corticosteroids and an aggressive management of infectious complications, allows for an acceptable safety profile in patients treated with CYC (AU)

Elastofibroma dorsi: revisión de 4 casos / Elastofibroma dorsi: review of 4 cases

El elastofibroma dorsi es un tumor benigno, poco frecuente, de tejido fibroelástico, más común en mujeres luego de la quinta década de vida. Se suele localizar en la región subescapular, pudiendo en ocasiones ser bilateral. Presentamos 4 pacientes, entre 53 y 73 años de edad, con esta patología. Frecuentemente es una lesión asintomática, aunque puede observarse dolor leve con resalto de la escápula al realizar movimientos. Todas nuestras pacientes presentaron dolor y una de ellas además resalto de la escápula. El diagnóstico se basa en los hallazgos clínicos y los estudios por imágenes, especialmente la ecografía, la tomografía computarizada y la resonancia magnética nuclear. La biopsia se reserva para los casos sospechosos que no presentan en los estudios por imágenes el patrón característico. En nuestra serie, la extirpación de la lesión fue necesaria en una de las enfermas, ya que en las demás la clínica y los estudios por imágenes permitieron arribar a un diagnóstico definitivo (AU)

Elastofibroma dorsi is a benign, uncommon fibroelastic tissue condition, more common in women after the fifth decade of life. It is usually located in the subscapular region, and can sometimes be bilateral. We present 4 patients, between 53 and 73 years of age, with this disease. It is often an asymptomatic lesion that can manifest, even at its apex, with mild pain when moving the scapula. All our patients had pain.The diagnosis is based on clinical findings and imaging studies, especially ultrasound, computed tomography, and nuclear magnetic resonance. The biopsy is reserved for patients who have no characteristic signs on imaging. In our series, surgical excision was necessary in one of the patients, and in the others, clinical and imaging studies allowed us to arrive at a definitive diagnosis (AU)

[Perception of mistreatment during medical residency training]. / Percepción de maltrato durante la capacitación de médicos residentes.

Because previous investigations show that mistreatment during residency is frequent we undertook this research to assess the prevalence of psychological abuse, physical violence and sexual harassment in residency training programs and the professional status of perpetrators. Through a literature review and a previous qualitative study we developed a self-administered questionnaire. Thirteen events that could be experienced by residents and ten possible perpetrators were described in the questionnaire. Residents were asked to record whether they had experienced these events, at least once, and who was responsible. This survey was distribuided among the residents from three hospitals of Buenos Aires city. A total of 322 residents answered the questionnaire (55% women) 72% of whom worked in clinical programs, 22% in surgical programs, and 6% in diagnostic programs. Mistreatment was reported by 89% of the residents. On average each resident recorded 8 different episodes of mistreatment, such as being criticized for not completing administrative work (75%), being shouted at (64%), being humiliated in public (57%), sexual harassment (10%), being exposed to pornographic material without permission (7%), being hit or pushed (15%), suffering racial or religious discrimination (10%). The most common perpetrators were senior residents (26%), chief resident (19%), attending physicians (14%), and nurses (8%). Mistreatment and abuse are commonly experienced by residents in training programs. A multidisciplinary approach is needed to address this problem in the training environment.
