Resultados funcionales de tratamiento con bevacizumab intravítreo en pacientes con retinopatía del prematuro / Functional results in children with retinopathy of prematurity treated with intravitreal bevacizumab

Objetivo El propósito del presente estudio es determinar la eficacia y describir los resultados funcionales en términos de agudeza visual y defecto refractivo a largo plazo del tratamiento con una dosis de bevacizumab intravítreo en pacientes con retinopatía del prematuro (ROP) tipo1 de alto riesgo. Métodos Se trata de un estudio clínico retrospectivo en el que se seleccionaron todos los pacientes con ROP preumbral tipo1 de alto riesgo tratados según práctica clínica habitual con bevacizumab intravítreo entre diciembre de 2013 y enero de 2018. Los pacientes con un seguimiento inferior a tres años fueron excluidos. Se registraron los datos de agudeza visual y refracción bajo cicloplejia de la última exploración oftalmológica realizada. Se definió la variable éxito como ausencia de retratamiento con anti-VEGF intravítreo o láser durante el tiempo de seguimiento. Resultados Se incluyeron en el análisis 76 ojos de 38 pacientes. Un total de 20 pacientes (40 ojos) tenían valoración de mejor agudeza visual corregida tomada utilizando la prueba de Snellen. La edad media de estos pacientes era de 6años (intervalo 4-9). La agudeza visual mediana fue de 0,80 (RIQ: 0,50; 1,00). Treinta y cuatro ojos (85%) tenían buena agudeza visual (mayor o igual a 0,5). Se obtuvo la refracción bajo cicloplejia de 74 ojos de 37 pacientes. La mediana del equivalente esférico en la última revisión fue de +0,94 (RIQ: −0,25; 1,88). La tasa de éxito fue del 96,05%. Conclusión El bevacizumab intravítreo es una terapia efectiva con buenos resultados funcionales para ROP tipo1 de alto riesgo. En nuestro estudio se observó buena respuesta al tratamiento, con una tasa de éxito superior al 95% (AU)

Background/aim The aim of the study is to describe the efficacy and to determine the functional outcome in terms of visual acuity and refractive defect of a single dose of intravitreal bevacizumab in patients with high-risk ROP type1. Methods In this retrospective clinical study patients diagnosed between December 2013 and January 2018 with high-risk pre-threshold ROP type1 and treated with intravitreal bevacizumab were selected. All patients were treated following the established protocol at our centre. Those patients with less than three-year follow-up were excluded. Visual acuity and cycloplegic refraction in the last visit were registered. Treatment efficacy was defined as the absence of retreatment with intravitreal anti-VEGF or laser during follow-up. Results A total of 38 infants (76eyes) were included in the analysis. Twenty infants (40eyes) completed visual acuity testing. Mean age was 6years (IQR: 4-9). Median visual acuity was 0.8 (IQR: 0.5-1). Thirty-four eyes (85%) had good visual acuity (greater than or equal to 0.5). Thirty-seven patients (74eyes) had cycloplegic refraction measured. Median spherical equivalent at the last visit was +0.94 (IQR: −0.25; 1.88). Treatment success rate was 96.05%. Conclusion Intravitreal bevacizumab treatment showed good functional outcome in patients with high-risk ROP type1. In our study, good response to treatment was observed with a success rate over 95% (AU)

Maintenance of angiogenesis inhibition with aflibercept after progression to bevacizumab in metastatic colorectal cancer: real life study in the Valencian community

Introduction The second-line chemotherapy in metastatic colorectal cancer (mCRC) with FOLFIRI-aflibercept demonstrated an increase in survival compared with FOLFIRI in patients previously treated with oxaliplatin-based regimens. Few data are available in patients treated previously with bevacizumab. Our objective is to evaluate the efficacy and safety of FOLFIRI-aflibercept in second-line treatment in patients who have previously received bevacizumab. Patients and methods This is a observational, retrospective study of patients with mCRC treated with FOLFIRI-aflibercept in 2nd line in eight hospitals in the Valencian Community. Survival, response, and toxicity were analyzed. Result 122 patients with a median age of 61 years were included. 89% of patients had PS 0–1. The median of PFS (progression free survival) and OS (overall survival) was 5.45 (95% CI 4.74–6.15 months) and 10.15 (95% CI 7.47–12.82 months), respectively. Disease control rate 59.8%. The most common grade 3–4 adverse events were neutropenia (13,1%) and asthenia (9%). The presence of hypertension during treatment with FOLFIRI-aflibercept was associated with a survival benefit. Median of OS was 14.45 (95% CI 11.58–17.32) in patients with hypertension vs 7.78 (95% CI 5.02–10.54) in patients without hypertension (p = .001). Our results suggest that the presence of PS 0, primary tumor surgery, metachronous metastases, and the presence of only 1 metastatic location, are favorable prognostic factors associated with better OS. Conclusions Our results confirm the value of maintaining angiogenesis inhibition with FOLFIRI-aflibercept in mCRC after progression to a first-line treatment with bevacizumab. The development of hypertension during treatment is a possible predictive marker of response (AU)

Risk factors for oral mucositis during chemotherapy treatmentfor solid tumors: a retrospective STROBE-guided study

Background: This study retrospectively analyzed the risk factors for transchemotherapy oral mucositis (OM).Material and Methods: Before each chemotherapy cycle, patients were routinely evaluated for the presence/severity of OM based on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 scale for adverse effectsand graded as follows: However, specific conditions such as mucositis are graded on a five-point scale: 0, absenceof mucositis, grade 1 (Asymptomatic or mild), 2 (Presence of pain and moderate ulceration, without interferencewith food intake), 3 (severe pain with interference with food intake) or 4 (Life-threatening with the need for urgentintervention). Information from 2 years of evaluations was collected and patient medical records were reviewed toobtain data on chemotherapy cycle, sex, age, body mass index, body surface area, primary tumor, chemotherapyprotocol, and history of head and neck radiotherapy. The X² test and multinomial logistic regression were used forstatistical analysis (SPSS 20.0, p<0.05).Results: Among 19,000 total evaluations of 3,529 patients during 5.32±4.7 chemotherapy cycles (CT) the prevalence of OM was 6.3% (n=1,195). Chemotherapy duration (p<0.001), female sex (p=0.001), adjuvant intention(p=0.008) and the use of carboplatin (p=0.001), cisplatin (p=0.029), docetaxel (p<0.001) and bevacizumab(p=0.026) independently increased the risk of mucositis. In head and neck tumors, 2018 year (p=0.017), chemotherapy duration (p=0.018), BMI>30 (p=0.008), radiotherapy (p=0.037) and use of carboplatin (p=0.046) andcyclophosphamide (p=0.010) increased this prevalence.Conclusions: Cycles of chemotherapy, sex, cytotoxicity drugs, bevacizumab and head and neck radiotherapy increase the risk of OM in solid tumors.

Eficacia de cidofovir frente a bevacizumab en la papilomatosis respiratoria recurrente: estudio piloto aleatorizado, doble ciego y controlado por placebo / Efficacy of cidofovir versus bevacizumab in recurrent respiratory papillomatosis: A randomized, double-blind, placebo-controlled pilot study

Objectives: After surgical resection of papilloma, adjuvant therapy may be recommended for the control of recurrent respiratory papillomatosis (RRP). As the efficacy of adjuvant therapy remains unproven, the aim of this study was to compare the efficacy of cidofovir versus bevacizumab used as adjuvant therapies for the control of RRP. Methods: This randomized, double-blind, placebo-controlled pilot study was performed in a national respiratory disease referral centre. Patients with RRP were recruited prospectively and were divided into juvenile or adult RRP. Participants were randomly assigned to receive adjuvant therapy with cidofovir, bevacizumab or placebo. The study drug or placebo was administered after direct microlaryngoscopy with papilloma resection using cold instruments. The Derkay severity score and the Voice Handicap Index (VHI) were assessed at 3–6-week intervals, for a total of 3 visits. Follow-up included VHI and Derkay score assessments at 2-month intervals over the course of one year. Annual rates before and after surgical treatment were compared. Results: Five children and 11 adults were enrolled in the study. After one year, the group treated with cidofovir had a significant decrease in Derkay score (p=.027). No difference between treatment arms was observed in the annual surgery rate. There was a significant decrease in the VHI score in all treatment groups (p<.001), and no significant difference was observed between groups (p=.32). Conclusion: While we observed a significant decrease in RRP severity with intralesional cidofovir, we were unable to provide proof of efficacy of intralesional bevacizumab. (AU)

Objetivos: Tras la extirpación quirúrgica de los papilomas, puede recomendarse terapia adyuvante para el control de la papilomatosis respiratoria recurrente (PRR). Como la eficacia de la terapia adyuvante no está demostrada, el objetivo de este estudio fue comparar la eficacia de cidofovir frente a bevacizumab, utilizados como terapias adyuvantes para el control de PRR. Métodos: Estudio piloto aleatorizado, doble ciego y controlado por placebo, realizado en un centro nacional de referencia de enfermedades respiratorias. Se reclutó prospectivamente a los pacientes con PRR, y se dividieron en 2 grupos: PRR de jóvenes y PRR de adultos. A los participantes se les asignó aleatoriamente la administración de terapia adyuvante de cidofovir, bevacizumab o placebo. La administración de los fármacos de estudio o placebo se realizó tras practicar microlaringoscopia directa con extirpación de papilomas, utilizando instrumental frío. Se llevaron a cabo evaluaciones utilizando la puntuación de gravedad de Derkay y la escala VHI (Voice Handicap Index) a intervalos de 3 a 6 semanas, con un total de 3 visitas. El seguimiento incluyó evaluación de las escalas VHI y Derkay a intervalos de 2 meses, durante el curso de un año. Se compararon las tasas anuales pre- y postratamiento quirúrgico. Resultados: El estudio incluyó 5 niños y 11 adultos. Transcurrido un año, el grupo tratado con cidofovir reflejó una reducción significativa en la escala Derkay (p=0,027). No se observó diferencia alguna entre las ramas terapéuticas en la tasa quirúrgica anual. Se vio una reducción significativa en la puntuación VHI en todos los grupos terapéuticos (p<0,001), y no se observó diferencia significativa entre los grupos (p=0,32). Conclusión: A pesar de verse una reducción significativa de la gravedad de PRR con la administración de cidofovir intralesional, no pudimos probar la eficacia de bevacizumab intralesional. (AU)

Patient profiles as an aim to optimize selection in the second line setting: the role of aflibercept

Colorectal cancer is the second leading cause of cancer-related death worldwide. For metastatic colorectal cancer (mCRC) patients, it is recommended, as first-line treatment, chemotherapy (CT) based on doublet cytotoxic combinations of fluorouracil, leucovorin, and irinotecan (FOLFIRI) and fluorouracil, leucovorin, and oxaliplatin (FOLFOX). In addition to CT, biological (targeted agents) are indicated in the first-line treatment, unless contraindicated. In this context, most of mCRC patients are likely to progress and to change from first line to second line treatment when they develop resistance to first-line treatment options. It is in this second line setting where Aflibercept offers an alternative and effective therapeutic option, thought its specific mechanism of action for different patient’s profile: RAS mutant, RAS wild-type (wt), BRAF mutant, potentially resectable and elderly patients. In this paper, a panel of experienced oncologists specialized in the management of mCRC experts have reviewed and selected scientific evidence focused on Aflibercept as an alternative treatment (AU)

Controversies in the treatment of RAS wild-type metastatic colorectal cancer

Objective To provide guidance for the management of RAS wild-type (wt) metastatic colorectal cancer (mCRC) in daily practice. Methods Nominal group and Delphi techniques were used. A steering committee of seven experts analyzed the current management of RAS wt mCRC, through which they identified controversies, critically analyzed the available evidence, and formulated several guiding statements for clinicians. Subsequently, a group of 30 experts (the expert panel) was selected to test agreement with the statements, through two Delphi rounds. The following response categories were established in both rounds: 1 = totally agree, 2 = basically agree, 3 = basically disagree, 4 = totally disagree. Agreement was defined if ≥ 75% of answers were in categories 1 and 2 (consensus with the agreement) or 3 and 4 (consensus with the disagreement). Results Overall, 71 statements were proposed, which incorporated the following areas: (1) overarching principles; (2) tumor location; (3) triplets; (4) maintenance; (5) second-line and beyond treatments; (6) Rechallenge and liquid biopsy. After the two Delphi rounds, only six statements maintained a lack of clear consensus. Conclusions This document aims to describe the expert’s attitude when dealing with several common clinical questions regarding patients with RAS wt mCRC (AU)

Tendencias en el tratamiento de la papilomatosis respiratoria recurrente / Trends in recurrent respiratory papillomatosis treatment

La papilomatosis respiratoria recurrente (PRR) consiste en tumores benignos en las vías respiratorias causados por la infección del virus del papiloma humano. Las lesiones pueden provocar cambios en la fonación y obstruir las vías respiratorias. El objetivo de este estudio es evaluar las diferentes terapias quirúrgicas y adyuvantes disponibles para el tratamiento de esta afección que se han reportado en los años recientes. Se realizó una búsqueda en PubMed de artículos sobre el tratamiento de la PPR publicados entre 2014 y 2018. De los encontrados, 40 artículos con 1.425 pacientes con PRR cumplieron con los criterios. De estos, 24 artículos evaluaban el uso de terapias adyuvantes como el bevacizumab, el cidofovir y la vacuna contra el virus del papiloma humano. Ha habido un aumento en las opciones terapéuticas adyuvantes para la PRR en los últimos años. El conocimiento de estas opciones resalta las lagunas y oportunidades en la atención de estos pacientes, abre la puerta a nuevos protocolos para controlar la enfermedad, aumenta los intervalos quirúrgicos y nos guía hacia nuevos caminos en el futuro

Recurrent respiratory papillomatosis (RRP) consist of benign tumours along the airway caused by human papillomavirus infection. Papillomas may cause changes in phonation and obstruct the airway. The purpose of this study was to evaluate the different surgical and adjuvant therapies available for the treatment of this condition reported between 2014-2018. A PubMed search was performed for RRP treatment articles published between 2014 -2018. Forty articles that encompassed 1425 patients with RRP met the criteria. Of these, 24 articles evaluate the use of adjuvant therapies such as bevacizumab, human papillomavirus vaccine and cidofovir. There has been an increase in adjuvant therapy options for RRP in the literature in recent years. An awareness of these options highlights gaps and opportunities in the care of these patients, opens the door to new protocols to control disease and increase intersurgical intervals, and guides us towards new management paradigms in the future

Bevacizumab in recurrent ovarian cancer: could it be particularly effective in patients with clear cell carcinoma?

Purpose Treatment of recurrent ovarian carcinoma is a challenge, particularly for the clear cell (CCC) subtype. However, there is a preclinical rationale that these patients could achieve a benefit from antiangiogenic therapy. To assess this hypothesis, we used the growth modulation index (GMI), which represents an intrapatient comparison of two successive progression-free survival (PFS). Methods We conducted a retrospective real-world study performed on 34 patients with recurrent ovarian cancer, treated with bevacizumab-containing regimens from January 2009 to December 2017. The primary endpoint was GMI. An established cut-off > 1.33 was defined as a sign of drug activity. Results 73.5% of patients had high-grade serous ovarian carcinoma (HGSOC), and 17.7% had CCC; 70.6% of patients received carboplatin/gemcitabine/bevacizumab, and 29.4% received weekly paclitaxel/bevacizumab. According to histological subtype, the overall response rate and median PFS were 52% and 14 months for HGSOC and 83.3% and 20 months for CCC, respectively. The overall population median GMI was 0.99; it was 0.95 and 2.36 for HGSOC and CCC, respectively. CCC subtype was significantly correlated with GMI > 1.33 (odds ratio 41.67; 95% confidence interval 3.6–486.94; p = .03). Conclusion Adding bevacizumab to chemotherapy in recurrent CCC is associated with a remarkable benefit in this cohort. The efficacy of antiangiogenic drugs in CCC warrants further prospective evaluation (AU)

Efectividad de los regímenes tratar y extender vs. pro re nata para el tratamiento de degeneración macular neovascular vinculada a la edad: una comparación en un entorno real / Effectiveness of treat-and-extend versus pro re nata regimens in the treatment of Neovascular Age Macular Degeneration: A Real World Comparison

OBJETIVO: Evaluar y comparar los resultados visuales y morfológicos de regímenes de tratamiento pro re nata (PRN) y tratar-y-extender (T&E) a tres años en la práctica clínica real. MÉTODOS: Un estudio retrospectivo de pacientes con degeneración macular vinculada a la edad neovascular (DMEN) tratadas con anti-VEGF con tres años de seguimiento continuo y sin tratamientos anti-VEGF anteriores. Se midieron la mejor agudeza visual corregida (MAVC), el espesor foveal central (EFC) y el número de inyecciones intravítreas para determinar diferencias estadísticas entre ambos grupos al inicio y a lo largo del seguimiento. RESULTADOS: Se incluyeron en el estudio un total de 240 ojos, 170 en el grupo PRN y 70 en el grupo T&E. A los 12 meses la ganancia media con respecto al inicio de MAVC (en letras ETDRS) llegó a su punto más alto en el grupo T&E (+ 6,38 ± 13,32; p = 0,25). En el grupo PRN, MAVC llegó al máximo a los tres meses y disminuyó lentamente hasta el final del seguimiento. Con ambos regímenes, desde el inicio el EFC continuó disminuyendo hasta el segundo año (PRN -138,81 [-846,7 a +162,77] y T&E -81 [-604 a +100] μm, p = 0,06). Posteriormente, el grupo T&E mantuvo esta tendencia, llegando al nivel más bajo de EFC a los 36 meses, mientras que el grupo PRN mostró un aumento en los valores de EFC (PRN -104 [-807,7 a +297] μm y T&E -103 [-575 a +244], μm p = 0,63). Los pacientes tratados con el régimen T&E recibieron un número significativamente mayor de inyecciones (PRN 16,3 ± 7,6 vs. T&E 23,9 ± 9,4, p <0,01). CONCLUSIÓN: Los resultados demostraron una tendencia de T&E a conseguir valores más altos de MAVC, llegando al máximo a los 12 meses, y grosores menores de EFC al final de tres años. A pesar del mayor número de inyecciones en el grupo T&E, la media de MAVC revirtió a los valores de base a los tres años

PURPOSE: Evaluate and compare the visual and morphological results of Pro re nata (PRN) and treat-and-extend (T&E) treatment regimens at 3 years in real world clinical practice. METHODS: Retrospective study of patients with neovascular age macular: degeneration (AMD) treated with anti-VEGF with 3 years of continuous follow-up and no previous anti-VEGF treatment. Best corrected visual acuity (BCVA), central foveal thickness (CFT) and number of intravitreal injections outcomes were tested for statistical differences between the two groups at baseline and during follow-up. RESULTS: A total of 240 eyes were included in the study, 170 in the PRN group and 70 in the T&E group. At 12 months, mean BCVA (ETDRS letters) gain from baseline was at its highest point in the T&E group (+6.38 ± 13.32; p = 0.25). In the PRN group, BCVA peaked at 3 months and slowly decreased until end of follow-up. With both regimens, from baseline, CFT continued to decrease until the second year (PRN -138.81 [-846.7 to +162.77] and T&E -81 [-604 to +100] μm, p = 0.06). After that, T&E group maintained this tendency, reaching the lowest CFT value at 36 months, whereas PRN group showed an increased in CFT values (PRN -104 [-807.7 to +297] μm and T&E -103 [-575 to +244], μm p = 0.63). Patients treated with T&E regimen received a significantly higher number of injections (PRN 16.3 ± 7.6 vs T&E 23.9 ± 9.4, p < 0.01). CONCLUSION: Our results demonstrated a trend towards for T&E to achieve higher marks in BCVA, peaking at 12 months, and lower CFT thickness at the end of three years. Despite the higher number of injections performed in the T&E group the mean BCVA reverts to baseline values at 3 years

Perforación espontánea de pelvis renal en paciente con cáncer de pulmón avanzado en tratamiento con avastin (bevacizumab). A propósito de un caso / Spontaneous renal pelvic perforation in a patient with advanced lung cancer receiving avastin (bevacizumab). About a case

INTRODUCCIÓN: Bevacizumab, es un anticuerpo monoclonal usado como terapia dirigida en bloqueo del factor de crecimiento endotelial vascular en diferentes tipos de enfermedades oncológicas y no oncológicas. Ha demostrado beneficios de supervivencia en el tratamiento de muchos tipos de tumores malignos, incluyendo el cáncer de pulmón. Como toda droga presenta efectos adversos, siendo uno de los más infrecuentes la perforación gastrointestinal y pocos casos de estenosis ureterales. Sin embargo no mencionan ni describen la perforación de segmentos del tracto urinario. OBJETIVO: Describir la perforación de la pelvis renal como efecto adverso al uso de Bevacizumab. DESCRIPCIÓN DE CASO: Se tiene paciente masculino de 67 años con cáncer de pulmón metastático en tratamiento con Bevacizumab quien presenta perforación de pelvis surenal. Se realiza pielografía evidenciando extravasación del contraste a nivel de pelvis renal izquierda y se coloca catéter doble J, con evolución clínica satisfactoria, y control tomográfico al mes sin evidencia de extravasación del contraste, retirándose catéter doble J. CONCLUSIÓN: La perforación de pelvis renal secundaria a Bevacizumab es infrecuente, pero hay que tenerla en cuenta en pacientes tratados con este fármaco

INTRODUCTION: Bevacizumab is a monoclonal antibody used as a targeted therapy in blocking vascular endothelial growth factor in different types of oncological and non-oncological diseases. It has demonstrated survival benefits in the treatment of many types of malignant tumors, including lung cancer. As all drugs have adverse effects, one of the most uncommon being gastrointestinal perforation and few cases of ureteral stenosis. However, they do not mention or describe the perforation of segments of the urinary tract. OBJECTIVE: To describe renal pelvic perforation as an adverse effect to the use of Bevacizumab. CASE DESCRIPTION: 67-year-old male patient with metastatic lung cancer being treated with Bevacizumab who has perforation of the renal pelvis is presented. A pyelogram was performed showing contrast extravasation at the left renal pelvis and a double J catheter was placed, with a satisfactory clinical course, and tomographic control at 1 month without evidence of extravasation of contrast, withdrawing double catheter J. CONCLUSION: Renal pelvic perforation secondary to Bevacizumab is infrequent, but it must be taken into account in patients treated with this drug

Review and update on drugs related to the development of osteonecrosis of the jaw

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a rare, but serious adverse effect of certain drugs, of which bisphosphonates are the most widely known. This pathology is also associated with other medications such as the biologic antiresorptive agent, denosumab and some antiangiogenics such as sunitinib, bevacizumab or aflibercept. Very recently, new medications have also been associated with osteonecrosis of the jaw (ONJ). The objectives were to update the list of medications associated with ONJ, to analyze the fundamental aspects of this list and to describe the level of evidence available. MATERIAL AND METHODS: A narrative bibliographic review was made, using the PubMed-MedLine, DOAJ and SCI-ELO databases. Additional information was obtained through the online Medication Information Centre of the Spanish Agency of Medicines and Medical Devices (AEMPS - CIMA), the websites of the US Food & Drugs Administration (Drugs@FDA) and the European Medicines Agency (EMA). RESULTS: The latest drugs identified as potential facilitators of this pathology include a number of anti-VEGF based antiangiogenic drugs and anti-TKI and different types of immunomodulators. Neither the level of evidence in this association nor the risk are equal for all these drugs. On the other hand, over the coming years, new drugs will be marketed with similar action mechanisms to those that are recognized as having this adverse effect. CONCLUSIONS: No effective therapy is currently known for the treatment of ONJ. Therefore, in order to prevent new cases of MRONJ, it is essential for all oral healthcare professionals to be fully up-to-date with the etiopathogenic aspects of this pathology and to be aware of those drugs considered to be a risk

Terapia combinada con bevacizumab y alteplasa para el tratamiento de hemorragias submaculares / Combined therapy with bevacizumab and alteplasa for the treatment of submacular hemorrhages

INTRODUCCIÓN: El uso combinado de bevacizumab y alteplasa intrarretiniano supone una alternativa de tratamiento de las hemorragias maculares que adquiere cada vez más relevancia. Además, su utilización en una única jeringa evita una inyección intrarretiniana reduciendo los posibles riesgos que conllevan. OBJETIVO: Confirmar la efectividad y seguridad de la combinación de bevacizumab y alteplasa in vivo para el tratamiento de hemorragias submaculares en pacientes con degeneración macular asociada a la edad y determinar si supone una alternativa de tratamiento válida. METODOLOGÍA: Estudio retrospectivo observacional de pacientes tratados con bevacizumab y alteplasa para hemorragias submaculares desde febrero de 2017 a febrero de 2018. Se revisó la situación clínica pre-intervención y a los 3 meses. Las variables revisadas para determinar la efectividad del tratamiento fueron el tamaño de la superficie de la hemorragia, el grosor retiniano y la agudeza visual. La seguridad se evaluó con la aparición de reacciones adversas. RESULTADOS: Fueron incluidos cinco pacientes, cuatro con un ojo afectado y uno con ambos, 60% hombres, con una mediana de edad de 78 años (68-89). Objetivamente se redujo el porcentaje de ocupación de la hemorragia de una media del 70% al 6% tras la intervención. El grosor retiniano disminuyó de 1.531 micras (1.891-1.195) a 516,8 micras (324-667). La agudeza visual mejoró en dos pacientes manteniéndose en el resto. Todos los pacientes refirieron subjetivamente mejoría tras la intervención. El tratamiento fue seguro por la ausencia de aparición de reacciones adversas. CONCLUSIONES: El tratamiento estudiado ha demostrado ser efectivo y seguro clínicamente

INTRODUCTION: The combined use of bevacizumab and intraretinal alteplase is an alternative treatment for macular hemorrhage that is becoming more and more relevant. In addition, its use in a single syringe prevents an intraretinal injection reducing the possible risks involved. OBJECTIVE: To confirm the effectiveness and safety of the combination of bevacizumab and alteplase in vivo for submacular hemorrhage in patients with macular degeneration associated with age and to determine whether it is a valid treatment alternative. MATERIAL AND METHODS: Observational retrospective study of patients treated with bevacizumab and alteplase for submacular hemorrhages from February 2017 to February 2018. The clinical situation was reviewed pre-intervention and at 3 months later. The variables reviewed to determine the effectiveness of the treatment were the size of the hemorrhage surface, the retinal thickness and the visual acuity. Safety was determined with the appearance of adverse reactions. RESULTS: Six eyes of five patients were included, 60% men, with a median age of 78 years (68-89). Objectively the percentage of occupation of the hemorrhage was reduced from an average of 70% to 6% after the intervention. The retinal thickness decreased from 1,531 microns (1,891-1,195) to 516.8 microns (324-667). Visual acuity improved in two patients and remained in the rest. All patients reported subjectively improvement after the intervention. The treatment was safe due to the absence of adverse reactions. CONCLUSIONS: The reviewed treatment has shown to be clinically effective and safe

Coroidopatía, retinopatía y neuropatía óptica hipertensiva en un paciente con fracaso de trasplante renal / Hypertensive choroidopathy, retinopathy and optic neuropathy in renal transplantation failure

Varón de 32 años que presenta una elevación grave de la tensión arterial con cifras de 200/140 mmHg tras fracaso de trasplante renal. Se observaron múltiples desprendimientos serosos retinianos, dilatación venosa y atenuación de las arteriolas, hemorragias retinianas y edema del disco óptico. Ante la imposibilidad de realizar una angiografía fluoresceínica, la angiotomografía y las imágenes en face-tomografía de coherencia óptica permitieron identificar las alteraciones vasculares en retina, coroides y coriocapilar. La angiotomografía y las imágenes en modo en face-tomografía de coherencia óptica pueden ser de gran utilidad en la identificación de lesiones oftalmológicas vasculares relacionadas con la hipertensión maligna de aquellos casos en los que no sea posible realizar una angiografía fluoresceínica

A 32 year-old man who presented with severe elevation of blood pressure after failure of kidney transplant. The patient had multiple serous retinal detachments, venous dilation, arteriolar narrowing, retinal haemorrhages, as well as optic disc oedema. Due to the impossibility of performing a fluorescein angiography, an angiotomography and en-face optical coherence tomography images were used to identify the vascular alterations in the retina, choroid, and choriocapillaris. Angiotomography and en face-optical coherence tomography mode images are very useful in cases where it is not possible to perform fluorescein angiography
