Introduction@#Epidermolysis Bullosa Acquisita (EBA) is a rare autoimmune blistering disease which presents in the skin and mucous membranes. The decrease in anchoring fibrils in the basement membrane zone causes separation of the epidermis from the dermis, resulting in its blistering presentation. The treatment plan will depend on the severity of the disease. The first-line treatment for mild EBA includes topical corticosteroids and immunomodulators such as dapsone and colchicine; while severe cases of EBA may be given intravenous immunoglobulins, systemic steroids, and immunosuppressants such as azathioprine and cyclophosphamide. @*Case Report@#This is a case of a 50-year-old Filipino male who presented with a 2-year history of vesicles and tense bullae which evolved into papules, plaques and erosions with scarring and milia formation on the scalp and trauma-prone areas of the trunk and extremities. Clinical examination revealed multiple, well-defined, irregularly shaped erythematous papules and plaques with crusts, scales, erosions, pearl-like milia and scarring on the chest, back, upper, and lower extremities. The oral mucosa was moist with some ulcers on the tongue. Histopathologic examination using Hematoxylin and Eosin (H&E) stain revealed the absence of the epidermis with retention of dermal papillae suggestive of subepidermal clefting. Further examination with direct immunofluorescence (DIF) revealed monoclonal immunoglobulin (IgG) deposits demonstrating an intense linear fluorescent band at the dermoepidermal junction, consistent with Epidermolysis Bullosa Acquisita. Overall, the combined administration of prednisone, azathioprine, and colchicine resulted only in transient and incomplete resolution of lesions in this case of EBA.@*Conclusion@#The management of EBA is mostly supportive with the goal of minimizing complications. Combination treatments using steroids, colchicine, and azathioprine have been reported with various results. Its management remains challenging as most cases are refractory to treatment.

OBJECTIVE@#The current study evaluated various new colchicine analogs for their anticancer activity and to study the primary mechanism of apoptosis and in vivo antitumor activity of the analogs with selective anticancer properties and minimal toxicity to normal cells.@*METHODS@#Sulforhodamine B (SRB) assay was used to screen various colchicine analogs for their in vitro cytotoxicity. The effect of N-[(7S)-1,2,3-trimethoxy-9-oxo-10-(pyrrolidine-1-yl)5,6,7,9-tetrahydrobenzo[a] heptalene-7-yl] acetamide (IIIM-067) on clonogenicity, apoptotic induction, and invasiveness of A549 cells was determined using a clonogenic assay, scratch assay, and staining with 4',6-diamidino-2-phenylindole (DAPI) and annexin V/propidium iodide. Mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) levels were observed using fluorescence microscopy. Western blot analysis was used to quantify expression of proteins involved in apoptosis, cell cycle, and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling. Pharmacokinetic and in vivo efficacy studies against Ehrlich ascites carcinoma (EAC) and Ehrlich solid tumor models were conducted using Swiss albino mice.@*RESULTS@#IIIM-067 showed potent cytotoxicity and better selectivity than all other colchicine analogs screened in this study. The selective activity of IIIM-067 toward A549 cells was higher among other cancer cell lines, with a selectivity index (SI) value of 2.28. IIIM-067 demonstrated concentration- and time-dependent cytotoxicity against A549 cells with half-maximal inhibitory concentration values of 0.207, 0.150 and 0.106 μmol/L at 24, 48 and 72 h, respectively. It also had reduced toxicity to normal cells (SI > 1) than the parent compound colchicine (SI = 1). IIIM-067 reduced the clonogenic ability of A549 cells in a dose-dependent manner. IIIM-067 enhanced ROS production from 24.6% at 0.05 μmol/L to 82.1% at 0.4 μmol/L and substantially decreased the MMP (100% in control to 5.6% at 0.4 μmol/L). The annexin V-FITC assay demonstrated 78% apoptosis at 0.4 μmol/L. IIIM-067 significantly (P < 0.5) induced the expression of various intrinsic apoptotic pathway proteins, and it differentially regulated the PI3K/AKT/mTOR signaling pathway. Furthermore, IIIM-067 exhibited remarkable in vivo anticancer activity against the murine EAC model, with tumor growth inhibition (TGI) of 67.0% at a dose of 6 mg/kg (i.p.) and a reduced mortality compared to colchicine. IIIM-067 also effectively inhibited the tumor growth in the murine solid tumor model with TGI rates of 48.10%, 55.68% and 44.00% at doses of 5 mg/kg (i.p.), 6 mg/kg (i.p.) and 7 mg/kg (p.o.), respectively.@*CONCLUSION@#IIIM-067 exhibited significant anticancer activity with reduced toxicity both in vitro and in vivo and is a promising anticancer candidate. However, further studies are required in clinical settings to fully understand its potential.

The present study aimed to investigate the inhibitory effect and mechanism of Isodon terricolous-medicated serum on lipopolysaccharide(LPS)-induced hepatic stellate cell(HSC) activation. LPS-induced HSCs were divided into a blank control group, an LPS model group, a colchicine-medicated serum group, an LPS + blank serum group, an I. terricolous-medicated serum group, a Toll-like receptor 4(TLR4) blocker group, and a TLR4 blocker + I. terricolous-medicated serum group. HSC proliferation was detected by methyl thiazolyl tetrazolium(MTT) assay. Enzyme-linked immunosorbent assay(ELISA) was used to measure type Ⅰ collagen(COL Ⅰ), COL Ⅲ, transforming growth factor-β1(TGF-β1), intercellular adhesion molecule-1(ICAM-1), α-smooth muscle actin(α-SMA), vascular cell adhesion molecule-1(VCAM-1), cysteinyl aspartate-specific proteinase-1(caspase-1), and monocyte chemotactic protein-1(MCP-1). Real-time PCR(RT-PCR) was used to detect mRNA expression of TLR4, IκBα, and NOD-like receptor thermal protein domain associated protein 3(NLRP3), nuclear factor-κB(NF-κB) p65, gasdermin D(GSDMD), and apoptosis-associated speck-like protein containing a CARD(ASC) in HSCs. Western blot(WB) was used to detect the protein levels of TLR4, p-IκBα, NF-κB p65, NLRP3, ASC, and GSDMD in HSCs. The results showed that I. terricolous-medicated serum could inhibit the proliferation activity of HSCs and inhibit the secretion of COL Ⅰ, COL Ⅲ, α-SMA, TGF-β1, caspase-1, MCP-1, VCAM-1, and ICAM-1 in HSCs. Compared with the LPS model group, the I. terricolous-medicated serum group, the colchicine-medicated serum group, and the TLR4 blocker group showed down-regulated expression of p-IκBα, NLRP3, NF-κB p65, GSDMD, and ASC, and up-regulated expression of IκBα. Compared with the TLR4 blocker group, the TLR4 blocker + I. terricolous-medicated serum group showed decreased expression of TLR4, p-IκBα, NLRP3, NF-κB p65, GSDMD, and ASC, and increased expression of IκBα. In conclusion, I. terricolous-medicated serum down-regulates HSC activation by inhibiting the TLR4/NF-κB/NLRP3 signaling pathway.

La enfermedad por el Coronavirus 2019 (COVID-19 - Coronavirus Disease 2019) es una patología respiratoria de humanos producida por la infección por un nuevo coronavirus identificado con la sigla SARS-CoV-2.1 El 11 de marzo de 2020 la Organización Mundial de la Salud (OMS) declaró al COVID-19 como una pandemia, y desde ese momento hasta el 31 mayo del 2021 se ha reportado aproximadamente para Argentina con más de 3.600.000 casos confirmados y 76.131 muertes.1,2 Al no existir un tratamiento farmacológico específico contra el virus hasta el momento, aunque los esteroides sistémicos han demostrado reducir la mortalidad en pacientes hospitalizados por COVID-19 con complicaciones respiratorias graves y que las heparinas son efectivas en la prevención de la trombosis venosa profunda también en casos graves, la comunidad científica se ha enfocado en la búsqueda y desarrollo de intervenciones antivirales, y en resignificar diferentes tipos de fármacos que se utilizan en otras indicaciones. El presente informe pretende evaluar si el empleo de colchicina es eficaz, seguro y resulta conveniente para el tratamiento de pacientes con COVID-19 en Argentina.

Abstract Objective The predisposing factors for pericarditis recurrence in the pediatric population have not yet been established. This study aimed to define the risk factors for the unfavorable prognosis of pediatric acute pericarditis. Methods This was a retrospective study that included all patients with acute pericarditis treated from 2011 to 2019 at a tertiary referent pediatric center. Results The study included 72 children. Recurrence was observed in 22.2% patients. Independent risk factors for recurrence were: erythrocyte sedimentation rate ≥ 50 mm/h (p = 0.003, OR 186.3), absence of myocarditis (p = 0.05, OR 15.2), C-reactive protein ≥ 125 mg/L (p = 0.04, OR 1.5), and non-idiopathic etiology pericarditis (p = 0.003, OR 1.3). Corticosteroid treatment in acute pericarditis was associated with a higher recurrence rate than treatment with non-steroid anti-inflammatory therapy (p = 0.04). Furthermore, patients treated with colchicine in the primary recurrence had lower recurrence rate and median number of repeated infections than those treated without colchicine (p = 0.04; p = 0.007, respectively). Conclusion Independent risk factors for recurrence are absence of myocarditis, non-idiopathic etiology pericarditis, C-reactive protein ≥ 125 mg/L, and erythrocyte sedimentation rate ≥ 50 mm/h. Acute pericarditis should be treated with non-steroid anti-inflammatory therapy. A combination of colchicine and non-steroid anti-inflammatory drugs could be recommended as the treatment of choice in recurrent pericarditis.

INTRODUCCIÓN: La evidencia actual muestra que la infección por el SARS-CoV-2 progresa en diferentes etapas. Los síndromes de dificultad respiratoria aguda (SDRA) se observan en una proporción significativa de pacientes frágiles, aproximadamente después de la segunda semana, y no se relacionan sólo con la replicación viral no controlada, sino también con la respuesta del huésped. La inflamación sistémica es el sello distintivo de los casos moderados a graves de COVID-19, desencadenando infiltrados pulmonares que provocan el síndrome respiratorio agudo severo (SARS). Los altos niveles de interleucina (IL) -1ß, IL-6, IL-18 y el factor de necrosis tumoral (TNF) son algunas de las muchas alteraciones inmunológicas en la fisiopatología del estado inflamatorio en pacientes con COVID-19. Las trampas extracelulares de neutrófilos o NETs son una malla de ADN que encierra histonas y proteínas antimicrobianas, liberadas por los neutrófilos al espacio extracelular (NET), que resultaron ser tóxicas para las células epiteliales pulmonares in vitro. Además, los niveles elevados de NET están presentes en el plasma de pacientes con COVID-19, y la presencia de estos componentes celulares fue al menos 10 veces mayor en los aspirados traqueales que en el plasma de los mismos pacientes.5 Luego de la activación viral del complejo proteico, principalmente en monocitos y células tisulares presentadoras de antígeno, se activan IL-1ß e IL-18. Ambos productos por su parte activan las células B, T y NK (natural killer) además de estimular la liberación de otras citocinas inflamatorias.6 Una activación aberrante del inflamasoma podría ser origen de la 'hiper' inflamación encontrada en pacientes hospitalizados con COVID-19. OBJETIVO: El objetivo del presente informe es evaluar parámetros de eficacia, seguridad, conveniencia y recomendaciones disponibles acerca del uso de colchicina para el tratamiento de pacientes con COVID-19. MÉTODOS: Efectos en la Salud: se desarrolló un protocolo sustentado en proyectos que resume activamente la evidencia científica a medida que la misma se hace disponible. Con este fin se utilizó la plataforma L- ove de Epistemonikos para identificar revisiones sistemáticas "vivas". Se seleccionaron aquellas con una calidad metodológica apropiada evaluada a través de la herramienta AMSTAR-2, y que a su vez llevaran un proceso de actualización frecuente. De cada una de las revisiones sistemáticas identificadas se extractaron los efectos de la intervención sobre los desenlaces priorizados como importantes o críticos y la certeza en dichos efectos. Para la priorización de los desenlaces se adoptó una perspectiva desde el paciente considerando sus potenciales preferencias. La selección se realizó por consenso entre los autores y supervisores del informe considerando los resultados de múltiples ejercicios de priorización publicados, realizados en el marco del desarrollo de distintas guías de práctica clínica. Implementación: Este dominio contempla dos subdominios: la existencia de barreras y facilitadores en nuestro contexto para la implementación de la tecnología evaluada no consideradas en los otros dominios analizados, y los costos comparativos en relación con otras intervenciones similares. Con el objetivo de emitir un juicio de valor sobre la magnitud de dichos costos, se utilizó como comparador al tratamiento con dexametasona, que ha demostrado ser una intervención accesible y de beneficios importantes en el contexto analizado. Recomendaciones: Para la identificación de recomendaciones sustentadas en evidencia y actualizadas, se utilizó la plataforma COVID recmap. Se seleccionaron aquellas guías con rigor metodológico apropiado según la herramienta AGREE II (> 70%) y se incorporaron sus recomendaciones al informe. RESULTADOS: Se identificaron dos revisiones sistemáticas vivas que cumplen con los criterios de inclusión del presente informe y que contienen información actualizada acerca de la intervención evaluada. Se identificaron 5 ECA que incluyeron 16.271 participantes en los que colchicina se comparó con la atención estándar u otros tratamientos. CONCLUSIONES: El cuerpo de evidencia disponible muestra con moderada certeza que, en pacientes con enfermedad moderada, severa o crítica, colchicina probablemente no se asocia con beneficios en desenlaces críticos como mortalidad, ingreso en asistencia ventilatoria mecánica o tiempo de mejoría clínica como así tampoco aumenta el riesgo de eventos adversos severos. En pacientes con enfermedad leve, de reciente comienzo (precoz), colchicina podría disminuir la necesidad de hospitalizaciones, aunque la certeza en dicho efecto es baja.

RESUMEN Objetivo: Identificar las características clínicas de los pacientes con gota y la forma de utilización de los medicamentos antigotosos en Colombia. Métodos: Estudio de corte transversal en el que se analizaron 310 historias clínicas de pacientes atendidos en el último trimestre del 2016 y que recibieron un medicamento antigotoso. Se identificaron variables sociodemográficas, clínicas, farmacológicas, comorbilidades y paraclínicas. Para cada medicamento antigotoso se determinó si el uso fue según las recomendaciones aprobadas por la Federal Drug Administration (FDA). Se realizaron análisis descriptivos, bivariados y multivariados. Resultados: Se evaluaron pacientes de 14 diferentes ciudades de Colombia, con un predominio masculino del 70,3% (n = 218) y una mediana de edad de 64 arios (RIC: 26-94 arios). El antigotoso más frecuentemente utilizado fue alopurinol (n = 255; 82,3%), seguido de colchicina (n = 54; 17,4%). Los diagnósticos hallados como indicación fueron: hiperuricemia (n = 181; 58,4%), gota (n = 34; 11%), artritis gotosa (n = 28; 9%). El 74,5% (n = 231) de las prescripciones tenía un uso aprobado según la FDA, especialmente alopurinol en el manejo de gota e hiperuricemias, mientras que colchicina se encontró siendo utilizada en indicaciones no aprobadas (n = 44; 81,4%). Las comorbilidades más frecuentes fueron hipertensión (68,4%) y dislipidemia (55,8%). Conclusiones: Los pacientes con gota en tratamiento farmacológico tienen una elevada frecuencia de comorbilidades cardiovasculares, y están siendo tratados con alopurinol para la prevención a largo plazo, mientras que una menor proporción recibe colchicina que comúnmente es utilizada para indicaciones no aprobadas por las agencias reguladoras.
ABSTRACT Objective: To identify the clinical characteristics of patients with gout, and the prescription patterns of anti-gout medications in Colombia. Methods: Cross-sectional study, that analysed the data from 310 medical records of patients treated in the last quarter of 2016, and who received an anti-gout medication. Sociodemographic, clinical, pharmacological, comorbidities, and paraclinical variables were identified. For each anti-gout drug used, it was determined whether the use was in accordance with Federal Drug Administration (FDA) approved recommendations. Descriptive, bivariate and multivariate analyses were performed. Results: Patients from 14 different cities in Colombia were evaluated, with a male predominance of 70.3% (n = 218) and a median age of 64 years (RIC: 26-94 years). The most frequently used anti-gout medication was allopurinol (n = 255; 82.3%), followed by colchicine (n = 54; 17.4%). The main diagnoses found as an indication were: hyperuricaemia (n=181, 58.4%), gout (n = 34; 11.0%), and gouty arthritis (n = 28; 9.0%). Almost three-quarters (74.5%; n = 231) of the prescriptions had an approved use according to the FDA, especially allopurinol in the management of gout and hyperuricaemia, while colchicine was found to be used in unapproved indications (n = 44, 81.4%). The most frequent comorbidities were hypertension (68.4%) and dyslipidaemia (55.8%). Conclusions: Patients with gout who are under pharmacological treatment have a high frequency of cardiovascular comorbidities. They were being treated with allopurinol for long-term prevention, while a smaller proportion received colchicine, which is often used for indications not approved by regulatory agencies.

Colchicine plays an important role in the treatment of gout and some other diseases. Besides gastrointestinal symptoms, myopathy has been reported as a rare side effect of colchicine in some patients. We report a case of myopathy in a patient with chronic kidney disease caused by high-dose colchicine, and then review literature on colchicine-induced myopathy, so as to provide some experience for the clinical diagnosis, treatment and medication safety. A 51-year-old male patient with 10 years of gout and 5 years of chronic kidney disease history and irregular treatment was admitted to the hospital with complaint of recurrent left wrist arthralgia and emerging lower extremities myalgia after intake of 40-50 mg colchicine in total within 20 days. Laboratory examinations showed significantly increased creatine kinase (CK) and then colchicine-induced myopathy was diagnosed preliminarily. After withdrawl of colchicine and implementation of hydration, alkalization and intramuscular injection of compound betamethasone, the symptoms of arthralgia and myalgia were relieved within 3 days and CK decreased to normal range gradually. According to literature reports, colchicine related myopathy was mostly characterized by proximal myasthenia and myalgia, accompanied by elevated CK level, which usually occurred days to weeks after initial administration of colchicine at the usual dosage in patients with renal impairment or a change in the underlying disease state in those receiving long-term therapy, and the features might remit within three to four weeks after the drug was discontinued. Electromyography of proximal muscles showed myopathy marked by abnormal spontaneous activity and muscle pathology waa marked by accumulation of lysosomes and autophagic vacuoles. Chronic kidney disease, liver cirrhosis, higher colchicine dose and concomitant cytochrome P450 3A4 (CYP3A4) inhibitors were associated with increased risk of myo-pathy. Based on the similar efficacy and lower adverse reaction rate compared with larger dosage, small dose of colchicine was recommended by many important current guidelines and recommendations in the treatment of gout. In consideration of potential risks, colchicine should be used with caution in patients with kidney or liver impairment, and in those taking CYP3A4 or P-glycoprotein inhibitors. For those patients, the drug dose should be adjusted and the latent adverse reactions should be monitored carefully.

La ausencia de tratamiento específico para COVID-19 demanda una revisión dinámica de la evidencia científica disponible que permita un manejo dirigido a lograr la mejoría clínica, reducción de complicaciones y una menor mortalidad. Los factores independientes de riesgo asociados a mayor mortalidad, falla ventilatoria y necesidad de ventilación mecánica incluyen edad avanzada, enfermedades crónico-degenerativas, obesidad, elevación de ferritina, LDH, ALT y AST, marcadores de incremento en la generación de trombina, datos de daño cardiaco (elevación de troponinas y NT-pro-BNP) y niveles de IL-6 elevados. En ausencia de antivirales de acción directa, el abordaje terapéutico temprano con terapia anti-IL-6, la supresión de la cascada inflamatoria y transducción de señales mediante uso de glucocorticoides, la profilaxis trombótica y anticoagulación, así como la inhibición de la trombogénesis y noxa cardiaca con el uso de colchicina, pueden ser considerados hasta el momento como medidas plausibles en el manejo de los pacientes con COVID-19 en estado moderado y grave. Remdesivir puede considerarse para el tratamiento de pacientes con lesión pulmonar severa sin falla ventilatoria, tras evidencia sólida que ha demostrado mejoría clínica y reducción de mortalidad. En el subgrupo de pacientes graves y bajo ventilación mecánica, el uso de plasma de paciente convaleciente ha producido mejoría clínica, aunque la evidencia es limitada. La pronación en el paciente despierto y bajo ventilación mecánica puede considerarse como medida para mejorar la oxigenación con poca influencia sobre la mortalidad. Esta revisión plantea las medidas terapéuticas disponibles al momento y la estratificación de riesgo para el manejo de pacientes con infección por SARS-CoV-2.
The absence of a specific treatment for COVID-19 demands a dynamic review of the available scientific evidence that allows a management aimed at achieving clinical improvement, reduction of complications, and lower mortality. Independent risk factors associated with increased respiratory failure, mechanical ventilation requirement, and mortality include older age, chronic illness, obesity, ferritin, LDH, ALT, and AST elevation, thrombin release markers, cardiac damage markers (troponins and NT-proBNP elevation) and elevated levels of IL-6. In the absence of specific antiviral agents, the early treatment of mild to severe COVID-19 using IL-6 inhibitors, suppression of inflammatory cascade and signal transduction by using glucocorticoids, use of antithrombotic prophylaxis and anticoagulation, as well as thrombogenesis and cardiac damage inhibition by using colchicine, could be considered as a plausible route. Another drug to be considered in patients with severe lung injury without respiratory failure is remdesivir, which has shown substantial evidence reducing mortality and clinical improvement. In severe COVID-19 and in those that require ventilatory assistance, convalescent plasma use has resulted in clinical improvement despite limited evidence. Prone positioning in awake and intubated patients might be considered to improve oxygenation with scarce effect on mortality. The present review aims to expose the current therapeutic options and risk stratification course for the management of SARS-CoV-2 positive patients.

Abstract Although low-density lipoprotein cholesterol is central to the development and progression of atherosclerosis, the role of inflammation in the atherosclerotic process is becoming better understood and appreciated. Chronic inflammatory conditions such as rheumatoid arthritis, lupus, psoriasis, HIV infection, and inflammatory bowel disease have all been shown to be associated with an increased blood levels of inflammatory biomarkers and increased risk of cardiovascular events. Evidence from observational studies suggests that anti-inflammatory therapy decreases this risk in these conditions. Clinical trials of anti-inflammatory drugs in patients with coronary disease have yielded mixed results. Drugs that have failed in recent trials include the P38 MAP kinase inhibitor losmapimod, the phospholipase A2 inhibitors darapladib and varespladib, and methotrexate. Canakinumab, an interleukin-1β inhibitor, reduced cardiovascular events in patients with coronary disease in the Canakinumab Anti-inflammatory Thrombosis Outcome Study (CANTOS). Canakinumab increased the rate of fatal infections in CANTOS and is very expensive; it is thus unlikely to be widely used for risk reduction in cardiology. On the other hand, colchicine is a safe and inexpensive anti-inflammatory drug. In the Colchicine Cardiovascular Outcomes Trial (COLCOT), where patients within 30 days of a myocardial infarction were randomized to low-dose colchicine or placebo and followed for a median of almost 2 years, colchicine treatment was associated with a 23% reduction (p=0.02) in cardiovascular events. Newer studies with anti-inflammatory drugs have the potential to improve outcomes of patients with atherosclerosis, just as low-density lipoprotein cholesterol-lowering drugs have done over the past two decades.
