Autoimmunity and Cancer: Two Stations on the Same Continuum.

INTRODUCTION: Autoimmunity has been associated with different types of cancer, including hematological malignancies like lymphomas, and solid tumors. Additionally, the potential role of medication-induced immunosuppression should be considered. AIM: Our study aimed to investigate the relationship between autoimmunity and the development of cancer, as well as the impact of immunosuppressive drugs on increasing cancer risk. METHODS: The study sample was composed of patients who developed cancer after the administration of biological agents for the treatment of autoimmune disorders. Selected patients were treated in our hospital between 1st January 2011 and 31st December 2021 and followed up in internal medicine, gastroenterology, or dermatology consult. From 434 patients with autoimmune diseases using biological agents, only 20 developed cancer, which was our final study sample. The data analysis was performed using the IQVIR package version 2.0.2 (IQVIA, Durham, NC). A p-value of <0.05 was considered statistically significant. RESULTS: We found a significant correlation between long-term corticosteroid therapy and an increased risk of cancer. However, the effect of biological therapies on cancer risk was not statistically significant. It's worth noting that our sample size was small, so we cannot extrapolate these findings. CONCLUSIONS: Physicians need to be aware that treating autoimmune diseases with immunosuppressive therapies may contribute to the development of cancer. Further research is needed to determine the impact of such treatments on cancer prognosis.

Aseptic Osteonecrosis of the Femoral Head: The Effect of Corticosteroid Therapy and Long COVID Syndrome.

SARS­CoV­2 infection remains a hot topic; it is characterized by its multi-systemic involvement. Corticosteroid intake has been the subject of worldwide attention as a potentially effective treatment against coronavirus disease 2019 (COVID-19). Corticosteroids are registered on the WHO list of essential medicines, easily accessible for a low price, and particularly useful for different categories of people. The authors highlight the impact of corticosteroid administration for COVID-19 treatment on the occurrence of aseptic osteonecrosis in the femoral head. They also examine the pace of onset in comparison to corticosteroid usage unrelated to COVID-19. This article presents a patient with osteonecrosis of the femoral head after taking corticosteroid therapy in the treatment of COVID-19. The dose taken by the patient is 90 mg of dexamethasone equivalent to 600 mg of prednisone. The patient experienced the onset of OTA, and the duration of development was three months, indicating a relatively brief period. Comparison was made with data from the literature from 6 months to 1 year after taking corticosteroids in a context outside of COVID-19.

Management of treatment-naïve diabetic macular edema patients: Review of real-world clinical data.

The high prevalence of Diabetic macular edema (DME) is a real global health problem. Its complex pathophysiology involves different pathways. Over the last decade, the introduction of intravitreal treatments has dramatically changed the management and prognosis of DME. Among the different treatment options, inhibitors of vascular endothelial growth factor (anti-VEGF) and intravitreal steroids implants represent the first-line therapy of DME. We conducted a review of electronic databases to compile the available evidence about the clinical management of DME in a clinical setting, with a special focus on treatment-naïve patients. Anti-VEGF therapies represent a valuable option for treating DME patients. However, many patients do not respond properly to this treatment and, due to its administration regimen, many patients receive suboptimal treatment in real life. Current evidence demonstrated that in patients with DME, DEX-i improved significantly both anatomic and visual outcomes. Besides eyes with insufficient anti-VEGF respond or recalcitrant DME cases, DEX-i can be effectively and safely used in treatment-naïve DME patients as first line therapy. DEX-i may be considered first line therapy in different clinical scenarios, such as DME eyes with a greater inflammatory component, patients with cardiovascular events, vitrectomized eyes, or those requiring cataract surgery. In conclusion, there are still many points for improvement pending in the clinical management of the patient with DME. Since DME treatment must follow a patient-tailored approach, selecting the best therapeutic approach for each patient requires a good understanding of the pathophysiology of DME.

The efficacy of oral corticoids in treating complex regional pain syndrome: A retrospective cohort study.

OBJECTIVES: There is growing evidence supporting the role of inflammatory mechanisms in complex regional pain syndrome (CRPS). Corticoids, as most effective anti-inflammatory drugs, are widely used in treating inflammation. The aim of this study was to retrospectively assess the efficacy of oral corticoid treatment in CRPS patients. METHODS: Patients treated at the center of pain medicine in the Erasmus University Medical Centre between January 2015 and January 2020 were approached to partake in this study. Medical records were screened for age, gender, medical history, duration of CRPS, and CRPS severity score. Also, treatment effect, dose and duration, pain scores (NRS), and side effects were extracted from medical records. In addition, global perceived effect was completed in patients treated with corticoids. RESULTS: Between January 2015 and January 2020, twenty-nine CRPS patients received corticoids and met the inclusion criteria. One extreme outlier was excluded and treatment effect was unknown for one patient. Average daily dose was 28.9 mg (range 10-30 mg) and the mean treatment duration was 10.5 days (7-21 days). Fourteen patients (51.9%) responded positively to treatment and thirteen (48.1%) did not respond. Side effects were reported in five patients (17.9%). CONCLUSIONS: Corticoid treatment was effective in more than half of the patients. With only mild side effects reported the treatment also appears to be relatively safe. Further research is needed to investigate the efficacy of corticoids in treating (early) CRPS, preferably in an intervention study.

Manejo de glomerulonefritis membranoproliferativa secundaria a infección por virus de hepatitis C / Management of membranoproliferative glomerulonephritis secondary to infection by hepatitis C virus

Las glomerulonefritis membranoproliferativas son ne-fropatías glomerulares poco frecuentes cuya prevalencia ha disminuido en nuestro medio. Presentan una histología característica y pueden asociarse a diferentes enfermeda-des. La presentación clínica es variada y su diagnóstico de-finitivo requiere realizar una biopsia renal. El tratamiento viene condicionado por la enfermedad de base, tratándose con inmunosupresores cuando existe una disminución del filtrado glomerular.Presentamos el caso de una mujer de 47 años con glo-merulonefritis membranoproliferativa secundaria a infec-ción por de virus de hepatitis C para describir el manejo de este tipo de pacientes, dado que se trata de una patología con una baja prevalencia (AU)

Membranoproliferative glomerulonephritis is an un-common condition that affects the glomeruli of the kid-neys; its prevalence has decreased in our environment. Membranoproliferative glomerulonephritis has a charac-teristic histology that can be associated to different diseas-es. The clinical presentation varies, and to achieve a defin-itive diagnosis a renal biopsy must be done. Treatment is based on the underlying disease; when a drop in glomer-ular filtration rate is detected, immunosuppressants are prescribed.We describe the management of a 47-year-old female with membranoproliferative glomerulonephritis second-ary to hepatitis C virus infection, a condition with very low prevalence (AU)

E-cigarette and Vaping-Induced Lung Injury (EVALI) Long Taken for Miliary Tuberculosis: A Rare Cause of Interstitial Lung Disease.

Electronic cigarettes, a recent and burgeoning product, are gaining traction among the general population. However, despite their growing popularity, there is a lack of comprehensive research on their potential health risks. A prominent concern is EVALI (electronic cigarette or vaping product use-associated lung injury), a newly recognized condition currently under intense investigation. Here, we report the case of a 24-year-old male with a history of chronic smoking e-cigarettes and vaping products heavily over the past year. He sought urgent care at the emergency room due to symptoms that had been present for seven days before seeking medical attention. These symptoms included a sudden onset of difficulty breathing at rest, an intermittent dry cough producing a small amount of greenish sputum, and occasional episodes of mild hemoptysis. Chest radiograph showed bilateral diffuse infiltrates including almost innumerable tiny interstitial nodules. Multiple lobes of the lungs were affected by consolidations and patches of ground-glass opacities in the chest high-resolution computed tomography (HRCT) image. Throughout the following week, the patient's health showed gradual improvement with the aid of supportive measures and corticosteroid treatment. As part of the recovery plan, the patient was released with a gradually reducing regimen of oral corticosteroids and was scheduled for regular outpatient monitoring. The progression of the recovery was notable through enhancements in clinical symptoms, biological markers, and radiological findings.

Adjuvants for balanced anesthesia in ambulatory surgery.

Balanced anesthesia relies on the simultaneous administration of different drugs to attain an anesthetic state. The classic triad of anesthesia is a combination of a hypnotic, an analgesic, and a neuromuscular blocker. It is predominantly the analgesic pillar of this triad that became more and more supported by adjuvant therapy. The aim of this approach is to evolve into an opioid-sparing technique to cope with undesirable side effects of the opioids and is fueled by the opioid epidemic. The optimal strategy for balanced general anesthesia in ambulatory surgery must aim for a transition to a multimodal analgesic regimen dealing with acute postoperative pain and ideally reduce the most common adverse effects patients are faced with at home; sore throat, delayed awakening, memory disturbances, headache, nausea and vomiting, and negative behavioral changes. Over the years, this continuum of "multimodal general anesthesia" adopted many drugs with different modes of action. This review focuses on the most recent evidence on the different adjuvants that entered clinical practice and gives an overview of the different mechanisms of action, the potential as opioid-sparing or hypnotic-sparing drugs, and the applicability specifically in ambulatory surgery.

Steroid responsive encephalopathy associated with autoimmune thyroiditis as a cause of acuteencephalopathy.

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), known as Hashimoto's encephalopathy (HE), represents a heterogeneous group of neurological and neuropsychiatric symptoms associated with a presence of antithyroid antibodies in case of other causes of encephalopathy were excluded. Clinical symptoms most commonly includes acute onset of encephalopathy, behaviour changes and cognitive dysfunction, epileptic seizures as well as cerebellar and extrapyramidal symptoms. Corticoids provides rapid and sustained therapeutic benefit in most patients and only a few patients require other immunosuppressive therapy such as plasmapheresis, intravenous immunoglobulins, or others. We present the cases of two patients with acute onset of encephalopathy, status epilepticus based on SREAT, with rapid improvement after steroid treatment.

Effectiveness and safety of fluocinolone acetonide intravitreal implant in diabetic macular edema patients considered insufficiently responsive to available therapies (REACT): a prospective, non-randomized, and multicenter study.

OBJECTIVE: To assess the effectiveness and safety of the intravitreal fluocinolone-acetonide implant (FAc-i) in patients with chronic diabetic macular edema who did not sufficiently respond to other available therapies. METHODS: This was a multicenter, prospective, non-randomized, and phase-IV observational study conducted on patients with recurrent-DME who were insufficient responders to currently available therapies (REACT-Study). The primary end-point was the mean change in best-corrected-visual-acuity from baseline to month-24 values. RESULTS: Thirty-one eyes from 31 patients were included in the study. Mean age was 68.0 ± 7.7 years, and 10 (32.3%) were women. Study patients had received 5.3 ± 7.3 previous DME treatments before starting the study. In the overall study sample, BCVA improved from 56.1 ± 12.3 letters at baseline to 62.4 ± 17.0 letters at month-24 (p = 0.0510). The eyes with a baseline BCVA < 70 ETDRS letters had a significant improvement in BCVA from 53.2 ± 10.2 letters at baseline to 61.5 ± 17.9 letters at month-24 (p = 0.0165). In the overall study population, central-subfoveal-thickness (CST) was significantly reduced from 474.0 ± 135.1 µm at baseline to 333.4 ± 135.6 at month-24 (p < 0.0001). Similarly, macular-volume (MV) was significantly reduced from 10.7 ± 2.7 mm3 at baseline to 9.6 ± 2.9 mm3 (p = 0.0027) at month-24. Among the 31 study eyes, 19 (61.3%) required an additional treatment for DME. Throughout the study, 9 (29.0%) eyes required ocular hypotensive medication for controlling their intraocular-pressure and 5 (16.1%) eyes underwent cataract surgery. CONCLUSIONS: In DME eyes who did not sufficiently respond to previous therapies, the FAc-i was associated with an improvement in visual and anatomic outcomes. There were no unexpected adverse-events.

Dexamethasone-cyclophosphamide pulse therapy outcomes comparing pemphigus vulgaris and pemphigus foliaceus groups in a Brazilian cohort study.

BACKGROUND: Dexamethasone-cyclophosphamide pulse (DCP) and dexamethasone pulse (DP) have been successfully used to treat pemphigus, but DCP/DP outcomes comparing pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are scarce. OBJECTIVE: To compare DCP/DP outcomes in a Brazilian cohort of PV and PF patients according to demographic and clinical data. METHODS: Retrospective analytical cohort study, reviewing medical charts of PV and PF patients (for DCP/DP Phases I‒IV consult Pasricha et al.16‒18). RESULTS: 37 PV and 41 PF patients non responsive to usual treatments were included similarly for DCP or DP therapy. Disease duration was longer among PF before DCP/DP prescription (p < 0.001); PF required a higher number of monthly pulses to acquire remission in Phase I (median 10 and 6 pulses, respectively; p = 0.005). DCP/DP outcomes were similar in both groups: remission in 37.8% of PV and 34.1% of PF after completed DCP/DP cycles following a median of 13 months (1-56 months follow-up); failure occurred in 13.5% of PV and 14.6% of PF in Phase I; relapse in 13.5% of PV and 12.2% of PF, and dropout in 27% of PV and 24.4% of PF in Phases II to IV. Mild side effects were documented. STUDY LIMITATIONS: The severity of PV and PF disease was not assessed by score indexes. CONCLUSIONS: PV and PF patients presented similar DCP/DP outcomes. DCP/DP should be initiated earlier in PF patients due to the longer duration of their disease in order to decrease the number of pulses and the duration of Phase I to acquire remission.

Tratamiento corticoide y variantes SARS-CoV-2: dos factores independientes de mortalidad por COVID-19 en un hospital comarcal / Corticoid treatment and SARS-CoV-2 variants: two independent factors associated with COVID-19 mortality in a Spanish regional hospital

Fundamento: Existe gran heterogeneidad en tasas de ingresohospitalario y mortalidad derivada entre olas de COVID-19, pudiendo deberse al perfil de paciente, las variantes virológicas, lostratamientos y las medidas preventivas. El objetivo de este trabajoes analizar los factores asociados a mortalidad de pacientes ingresados por infección COVID-19 hasta finales de 2021.Métodología: Estudio de cohortes retrospectivo de pacientes COVID-19 en el Hospital General de Barbastro durante 2020 y 2021.Los datos se obtuvieron del Conjunto Mínimo Básico de Datos(CMBD), de registros de Microbiología y de prescripción electrónica de fármacos.Resultados: En el periodo de estudio ingresaron consecutivamente 908 pacientes por COVID-19 (mediana de 70 años, 57,2%varones), de los que 162 fallecieron (17,8%). Identificamos sieteolas epidemiológicas sucesivas. Las variables significativamenteasociadas a una mayor mortalidad fueron: edad, antecedentesde hipertensión arterial, insuficiencia renal crónica, demencia,EPOC, insuficiencia cardiaca, ictus previo, puntuación Charlsony la ola 2; la ola 4 se asoció a mayor supervivencia. En el análisismultivariante las variables asociadas a mayor mortalidad fueron:edad (OR=1,11; IC95%: 1,09-1,14), EPOC (OR=2,33; IC95%: 1,18-4,57), y las olas 2 (OR=2,57; IC95%: 1,10-6,00) y 3 (OR=2,94; IC95%:1,17-7,38); el tratamiento con glucocorticoides actuó como factorprotector (OR=0,29; IC95%: 0,14-0,62).Conclusiones: Este estudio confirma la utilidad terapéutica de losglucocorticoides para disminuir la mortalidad hospitalaria porCOVID-19. La diferente mortalidad entre las distintas olas epidemiológicas sugiere un papel directo de las variantes virológicascomo determinantes de la letalidad, independientemente de losantecedentes del paciente.(AU)

Background: Pandemic inter-wave hospital admissions andCOVID-19-related mortality rates vary greatly. Some of thefactors that may be playing part in this are the profile of thepatients, viral variants, pharmacological treatments, or preventive measures. This work aimed to analyze the factors associated with mortality in COVID-19 patients admitted to hospitalduring 2020-2021.Methods: Retrospective cohort study with COVID-19 patientsadmitted to Hospital de Barbastro (Spain) during 2020-2021. Datawere collected from the Spanish Conjunto Mínimo Básico de Datos and microbiology and electronic prescription records.Results: During the study period, 908 patients were consecutively admitted for COVID-19 (median age 70 years, 57.2%males); 162 (17.8%) patients died. We identified seven successive epidemiological waves. The following variables significantly associated to higher mortality: age, arterial hypertension,chronic renal failure, dementia, chronic obstructive pulmonarydisease, heart failure, prior stroke, Charlson index, and wave2; wave 4 was associated to greater survival. The multivariateanalysis showed that age (OR=1.11; 95% CI: 1.09-1.14), chronic obstructive pulmonary disease (OR=2.33; 95% CI: 1.18-4.57),wave 2 (OR=2.57; 95% CI: 1.10-6.00), and wave 3 (OR=2.94; 95%CI: 1.17-7.38) associated with higher mortality. Glucocorticoidtreatment was the only protective factor (OR=0.29; 95%CI: 0.14-0.62).Conclusions: This study confirms the therapeutic utility of glucocorticoids to reduce in-hospital mortality due to COVID-19.Heterogeneous mortality rates between the different COVID-19waves suggest a direct role of viral variants as determinants oflethality, regardless of the patient’s history.(AU)

Congenital lamellar ichthyosis complicated with erosive pseudo pustulosis: A rare clincal entity. About a case and review of the literature.

INTRODUCTION: Lamellar ichthyosis is a rare congenital disorder that can be encountered by plastic surgeon in a daily practice. Its clinical diagnosis makes it an significant pathology to identify and to know how to treat. MATERIAL AND METHODS: We report the case of a patient suffering from lamellar ichthyosis complicated by erosive pseudo pustulosis of the scalp. Our treatment protocol with two intra-lesional delayed-corticoids (Kenacort ®) injections three months apart showed significant clinical improvement of the lesions. DISCUSSION: Congenital lamellar ichthyosis regroups various clinical presentations. Most of the therapeutic strategies described in the literature involve local and systemic treatments, weighing on patients and leading to modest results. Surgical treatment or hyaluronic injections have also been reported but they raise problematics regarding morbidity and efficiency. CONCLUSION: Our therapeutic strategy by two Kenacort ® injections three months apart is simple, reproductible and has shown efficiency in the treatment of our patient suffering from congenital lamellar ichthyosis complicated with erosive pseudo pustulosis of the scalp.

Doping in Racing Pigeons (Columba livia domestica): A Review and Actual Situation in Belgium, a Leading Country in This Field.

Pigeon racing is a sport in which trained homing pigeons (Columba livia domestica) are released between 60 and 1200 km from their loft and then have to return home as quickly as possible. The first race was held in 1818 in Belgium and since then, Belgium has led the world in pigeon breeding. Unfortunately, as in other sports, doping has become a major issue and doping controls have been implemented. This review provides information about pigeon racing, rules from the Royal Federation Colombophile of Belgium, and laws applicable in Belgium as doping control issues cannot be understood without including them as part of pigeon racing. The main pharmacological data concerning corticoids, non-steroidal anti-inflammatory drugs, anabolic steroids, pain relievers and narcotic analgesics, bronchodilators and ß-agonists, drugs acting on the central nervous system and other performance-enhancing drugs, in addition to methods relevant to doping in pigeons are presented. Moreover, the chosen matrix and analytical methods are described.

[Interest of Apremilast in idiopathic recurrent aphthous stomatitis: Review of two clinical cases]. / Intérêt de l'Aprémilast dans les stomatites aphteuses récurrentes idiopathiques : étude de deux cas cliniques.

INTRODUCTION: Apremilast is a phosphodiesterase 4 inhibitor used in psoriasis and psoriatic arthritis Recently, this treatment has received marketing authorization for severe and refractory oral aphthosis in Behçet's disease. Idiopathic recurrent aphthous stomatitis (RAS) outside of Behçet's disease is often difficult to treat and can affect patients' quality of life. CASE REPORTS: We report our experience with the use of apremilast in two 49-year-old patients with refractory oral aphthosis not related to Behçet's disease or another etiology. In both cases, a combination of apremilast with low-dose prednisone controlled the idiopathic RAS within a few weeks. CONCLUSION: Apremilast, which already has marketing authorization for Behçet's disease, also appears to be effective in RAS.

Approaches to the Potential Therapy of COVID-19: A General Overview from the Medicinal Chemistry Perspective.

In spite of advances in vaccination, control of the COVID-19 pandemic will require the use of pharmacological treatments against SARS-CoV2. Their development needs to consider the existence of two phases in the disease, namely the viral infection and the inflammatory stages. The main targets for antiviral therapeutic intervention are: (a) viral proteins, including the spike (S) protein characteristic of the viral cover and the viral proteases in charge of processing the polyprotein arising from viral genome translation; (b) host proteins, such as those involved in the processes related to viral entry into the host cell and the release of the viral genome inside the cell, the elongation factor eEF1A and importins. The use of antivirals targeted at host proteins is less developed but it has the potential advantage of not being affected by mutations in the genome of the virus and therefore being active against all its variants. Regarding drugs that address the hyperinflammatory phase of the disease triggered by the so-called cytokine storm, the following strategies are particularly relevant: (a) drugs targeting JAK kinases; (b) sphingosine kinase 2 inhibitors; (c) antibodies against interleukin 6 or its receptor; (d) use of the traditional anti-inflammatory corticosteroids.

Resultados a largo plazo de tocilizumab para el tratamiento de arteritis de Takayasu en la práctica clínica / Long-term results of tocilizumab for the treatment of Takayasu arteritis in clinical practice

La arteritis de Takayasu (AT) es una enfermedad rara descrita como una vasculitis granulomatosa que afecta a las arterias elásticas de gran calibre, fundamentalmente la aorta y sus ramas principales. Como consecuencia de la inflamación de estos grandes vasos, puede dar lugar a la formación de aneurismas, estenosis u oclusión vascular. Afecta principalmente a mujeres jóvenes y los síntomas incluyen: síncope, mareo, disminución o ausencia de pulso, y alteración de la visión. El tratamiento convencional se basa principalmente en la utilización de corticoides e inmunosupresores, aunque recientemente se ha comenzado a considerar el uso de fármacos biológicos. Tocilizumab es un anticuerpo monoclonal dirigido contra IL-6 utilizado fuera de ficha técnica en algunos pacientes para tratar esta patología. Presentamos dos casos clínicos que describen el uso a largo plazo de tocilizumab en pacientes con AT refractaria al tratamiento convencional. En ambos casos se observó una excelente respuesta a tocilizumab, con remisión de la sintomatología y reducción de las dosis de corticoides asociados. No se registraron eventos adversos asociados al tratamiento. (AU)

Takayasu arteritis (TA) is a rare disease described as a granulomatous vasculitis that affects large-caliber elastic arteries, mainly the aorta and its main branches. As consequence of inflammation of these great vessels, TA can lead to the formation of aneurysms, stenosis or vascular occlusion. This pathology mainly affects young women and symptoms include: syncope, dizziness, decreased or absent pulse, and visual impairments. Conventional treatment is mainly based on the use of corticosteroids and immunosuppressants, although biological drugs has recently begun to be considered. Tocilizumab is a monoclonal antibody directed against IL-6 used off-label in some patients to treat this pathology. We present two clinical cases describing the long-term use of tocilizumab in patients with TA refractory to conventional treatment. In both cases, an excellent response to tocilizumab with remission of symptoms and a reduction in associated corticosteroid doses was observed. No adverse events associated with treatment were collected. (AU)

Controversia justificada acerca de los esteroides particulados epidurales / A justified controversy about epidural particulate steroids

Introducción: La administración epidural de esteroides constituye un pilar del tratamiento del dolor radicular cervical y lumbosacro. Objetivo: Describir los mecanismos fisiológicos y características farmacológicas de los corticosteroides utilizados en el tratamiento del dolor, así como las complicaciones derivadas de la administración epidural de esteroides particulados. Métodos: Se realizó una revisión no sistemática de la literatura en bases de datos científicas como Cochrane Database of Systematic Reviews, Pubmed/Medline, EMBASE, Scopus, Web of Science, EBSCOhost, ScienceDirect, OVID y el buscador académico Google Scholar, en los meses de julio a septiembre del año 2020. Desarrollo: Los corticoides utilizados en la medicina del dolor son derivados de la prednisolona. Estos se clasifican en particulados (de depósito, de suspensión) o no particulados (de dilución), en función de la presencia o ausencia de un componente molecular sólido (moléculas tipo éster, insolubles en agua). Los fármacos más empleados son la dexametasona, betametasona, triamcinolona y metilprednisolona. Conclusiones: La administración epidural de esteroides particulados está relacionada con la incidencia de complicaciones graves, aunque poco frecuentes, como paraplejía, tetraplejía, infarto de la médula espinal, hemorragia y edema cerebral. La evidencia disponible muestra una efectividad analgésica similar a los compuestos no particulados. Por lo tanto, no se recomienda su utilización rutinaria durante el abordaje del espacio epidural(AU)

Introduction: Epidural administration of steroids is a cornerstone for the treatment of cervical and lumbosacral radicular pain. Objective: To describe the physiological mechanisms and pharmacological characteristics of the corticosteroids used for pain treatment, as well as the complications derived from the epidural administration of particulate steroids. Methods: A nonsystematic review of the literature was carried out, from July to September 2020, in scientific databases such as Cochrane Database of Systematic Reviews, Pubmed/Medline, EMBASE, Scopus, Web of Science, EBSCOhost, ScienceDirect, OVID and the academic search engine Google Scholar. Development: The corticoids used in pain medicine are derived from prednisolone. These are classified into particulate (deposit, suspension) or non-particulate (dilution), depending on the presence or absence of a solid molecular component (ester-type molecules, insoluble in water). The most commonly used drugs are dexamethasone, betamethasone, triamcinolone, and methylprednisolone. Conclusions: The epidural administration of particulate steroids is related to the incidence of serious, although infrequent, complications, such as paraplegia, tetraplegia, spinal cord infarction, hemorrhage and cerebral edema. Available evidence shows analgesic effectiveness similar to that of non-particulate compounds. Therefore, its routine usage is not recommended during the managment of the epidural space(AU)
