Spotlight on risankizumab and its potential in the treatment of plaque psoriasis: evidence to date
Get PDFPsoriasis is a common chronic immune-mediated skin disease, with systemic involvement and significant impact in patients' quality of life. Several highly specific treatments have been developed over the years, such as tumor necrosis factor-α inhibitors, a nonselective IL-23 inhibitor (ustekinumab), and most recently IL-17 inhibitors. Risankizumab is a monoclonal antibody which targets IL-23p19 without binding IL-12. This novel therapeutic approach is expected to have advantages over the recently approved anti-IL-17 agents, such as the avoidance of Candida infections and neutropenia. In addition, unlike ustekinumab, the selective inhibition of IL-23 may preserve IL-12-dependent functions such as protection against infections and tumor immune surveillance. Risankizumab showed an excellent efficacy when compared to placebo and ustekinumab, with higher Psoriasis Area Severity Index (PASI) 75, PASI 90, and PASI 100 rates, along with a convenient every 12-week maintenance dosing regimen. Overall, risankizumab was well tolerated and the most common adverse event was upper respiratory tract infection. In the near future, further data will be available not only in psoriasis but also in Crohn's disease and psoriatic arthritis fields. Head-to-head trials comparing risankizumab with other IL-23 inhibitors and with IL-17 inhibitors will be crucial to reveal the role of risankizumab in the treatment of psoriasis.info:eu-repo/semantics/publishedVersio
Bloqueio peribulbar combinado com anestesia geral em bebês submetidos a tratamento a laser para retinopatia da prematuridade: uma análise retrospectiva
Get PDFBackground and objectives: Currently there is no agreement regarding which one is the most adequate anesthetic technique for the treatment of retinopathy of prematurity. Peribulbar block may reduce the incidence of oculocardiac reflex and postoperative apnea. The goal of this study was to report the outcomes of peribulbar block, when combined with general anesthesia, for the laser treatment for retinopathy of prematurity, in premature babies.
Methods: A retrospective analysis of anesthetic records of all babies who underwent laser treatment for retinopathy of prematurity from January 2008 through December 2015 in a tertiary hospital was performed.
Results: During that period a total of six babies was submitted to laser treatment for retinopathy of prematurity, all under peribulbar block combined with general anesthesia. A single infratemporal injection of 0.15mL.kg-1 per eye ropivacaine 1% or 0.75% was performed. At the end of the procedure, all babies resumed spontaneous ventilation. No perioperative complications were reported.
Conclusions: Peribulbar block was a safe anesthetic technique in our sample considered.Justificativa e objetivos
Até o momento não há um consenso sobre a técnica anestésica mais adequada para o tratamento de retinopatia da prematuridade. O bloqueio peribulbar pode reduzir a incidência de reflexo oculocardíaco e apneia no pós‐operatório. O objetivo deste estudo foi relatar os resultados do bloqueio peribulbar, quando combinado com anestesia geral, para o tratamento a laser de retinopatia da prematuridade em bebês prematuros.
Métodos
Uma análise retrospectiva dos registros anestésicos de todos os bebês submetidos ao tratamento a laser para retinopatia da prematuridade de janeiro de 2008 a dezembro de 2015 foi realizada em um hospital terciário.
Resultados
Durante esse período, seis bebês foram submetidos ao tratamento a laser para retinopatia da prematuridade, todos sob bloqueio peribulbar combinado com anestesia geral. Uma injeção infratemporal única de ropivacaína a 1% ou 0,75% (0,15 mL.kg−1) foi administrada por olho. No fim do procedimento, todos os bebês retomaram a ventilação espontânea. Não foram relatadas complicações perioperatórias.
Conclusões
O bloqueio peribulbar foi uma técnica anestésica segura em nossa amostra considerada.info:eu-repo/semantics/publishedVersio
Dermatose bolhosa IgA Linear: relato de um caso exuberante e revisão da literatura
No full textIntroduction: Linear IgA dermatosis (LIGAD) is a rare acquired disease, with a probable autoimmune origin. Its differential diagnosis involves other bullous dermatosis.
Case Report: A previously healthy 12-month-old male was observed at the Emergency Department due to a 4-day itchy vesiculobullous rash in the perineal region, lower abdomen, hands, and feet. Analytical study was normal. Flucloxacillin and hydroxyzine were initiated without improvement. New (some of which confluent) lesions, erosions, and serohematic crusts developed on the periphery of previous lesions. A skin biopsy was performed at this time, revealing a subepidermal blister with neutrophilic infiltrate at histological examination. Direct immunofluorescence uncovered linear IgA deposits along the basement membrane. Lesion remission occurred without further therapeutic measures.
Discussion: Although clinically exuberant, LIGAD is usually a self-limited disease. A high degree of suspicion is important, since immunofluorescence is diagnostic and pathognomonic, avoiding late diagnosis, unnecessary treatments, and parental anxiety.Introdução: A dermatose IgA linear (DIGAL) infantil é uma doença adquirida rara, de origem autoimune provável, que implica diagnóstico diferencial com outras dermatoses bolhosas.
Caso Clínico: Uma criança de 12 meses, saudável, do género masculino, foi observada no Serviço de Urgência por erupção vesico-bolhosa, pruriginosa, com quatro dias de evolução, na região perineal, abdominal inferior, mãos e pés. O estudo analítico não revelou alterações. A criança iniciou flucloxacilina e hidroxizina, sem melhoria. Verificou-se o aparecimento de novas lesões (algumas confluentes) na periferia das antigas, assim como erosões e crostas serohemorrágicas. Foi efetuada uma biópsia cutânea, cujo exame histológico revelou bolha subepidérmica com infiltrado neutrofílico. A imunofluorescência direta revelou depósitos lineares de IgA ao longo da membrana basal. Observou-se evolução com remissão das lesões sem medidas terapêuticas adicionais.
Conclusão: A DIGAL, apesar de clinicamente exuberante, é geralmente autolimitada. É necessário um elevado índice de suspeição, já que a imunofluorescência é diagnóstica e patognomónica, permitindo evitar diagnósticos tardios, tratamentos desnecessários e ansiedade parental
Adult blaschkolinear acquired inflammatory skin eruption (BLAISE) with simultaneous features of lichen striatus and blaschkitis
Get PDFBlaschkitis and lichen striatus are generally distinguished in the literature by the age of onset, lesion distribution, and histopathology. However, there is currently no clear consensus among authors about whether to consider blaschkitis and lichen striatus different clinical entities or a spectrum ofthe same disease. We present a case of adult BLAISE with features of both lichen striatus and blaschkitis, which seems to support the theory that these clinical entities may in fact represent a spectrum of the same pathological process.info:eu-repo/semantics/publishedVersio
Arterio-arterial graft – an option for hemodialysis patients with exhaustion of venous patrimony
Get PDFIntroduction: Vascular access (VA) for hemodialysis (HD) is the lifeline for End Stage Renal Disease (ESRD) patients. Long-term HD patients often have exhaustion of their venous patrimony for an autologous VA construction and, sometimes, even for a central venous catheter (CVC) placement. Case report: We describe the case of a 43-year-old woman with ESRD due to lupus nephritis, on maintenance HD since 2009. She also had secondary antiphospholipid syndrome and was chronically anticoagulated. Nevertheless, the patient had multiorgan thrombotic events (without sequelae) and several episodes of irreversible thrombosis of arteriovenous fistulas. Her HD course was also marked by multiple severe CVC infections, at diferente locations; a hemoperitoneum during cholecystectomy, and an immediate thrombosis of the renal artery of a kidney transplant. She was admitted to our hospital after an irreversible dysfunction of a right jugular CVC, with documentation of thrombosis of the superior and inferior vena cava. Exhaustion of the venous patrimony for HD was assumed and it was decided to make an arterio-arterial graft (AAG) of early cannulation. The first cannulation of the AAG was performed two days after surgical intervention, with no complications. The patient performed a twelve hour per week HD treatment with good efficiency.
Conclusion: AAG is an alternative for HD patients who have exhausted all their venous patrimony and it can be considered prior to the placement of a CVC as their sole remaining vascular access.info:eu-repo/semantics/publishedVersio
Acute tubulointersticial nephritis with uveitis: A report of two cases
Get PDFTubulointersticial nephritis and uveitis syndrome is an idiopathic and rare cause of acute kidney injury that should not overlooked, because it usually requires specific therapeutic interventions.
We report two distinct cases: a young and an elder female. Both cases presented with unspecific constitutional symptoms but had different onset of renal and ocular involvement. Both were treated with topical and systemic corticoids and although there was a good initial response in both cases, an early relapse after steroids taper was observed in the younger patient and a persistent renal dysfunction in the older one.
A high clinical suspicion and understanding of this disease is necessary for an adequate management and treatment of these patients. Recent data associates a worse renal prognosis when the disease appears in advanced age. In both of our cases the outcome was good but we had a short follow-up. The histological presentation of this disease in our older patient was similar to that reported in the literature, with a high percentage of fibrosis and chronicity of renal tissue that can contribute to the higher grade of renal dysfunction in this type of patients.info:eu-repo/semantics/publishedVersio

Clinical implications of anti-HLA antibodies testing in kidney transplantation
Get PDFAlloantibodies against donor human leukocyte antigens (HLA), termed as donor‑specific antibodies (DSA), are one of the most important factors for both early and late kidney allograft dysfunction. In the past, these antibodies were mainly detected through cell‑based crossmatch tests. Recently, new techniques such as solid phase immunoassays (SPI) have revealed these antibodies in patient sera with a high degree of detail, previously unimaginable. They have allowed us to accurately determine recipients’ allosensitization status, improve pre‑transplant risk assessment with a potential donor and post‑transplant alloimmune monitoring. However, the high sensitivity of these new assays has also created areas of uncertainty about their clinical impact.
In the pre‑transplant setting, the presence of preformed DSA has been associated with an increased risk of antibody‑mediated rejection (AMR) and subsequent allograft loss. Nevertheless, several studies have shown that not all DSA are deleterious. Hence, understanding the clinical correlations of DSA characteristics, namely strength, HLA class, complement‑fixing ability or IgG subclasses, is paramount for an adequate stratification of the immunological risk at transplant. Furthermore, given that the number of allosensitized patients on waiting lists is increasing, the added information from these new SPI is essential to improve their chance of being transplanted with an admissible immunological risk.
After transplantation, the appearance of de novo DSA (dnDSA) has also been associated with a deleterious effect on kidney allograft survival. Moreover, it has been acknowledged that a majority of late allograft failures are caused by alloantibody‑driven injury. The current challenges, in this setting, are determining cost‑effective DSA screening protocols and understanding which patients could benefit from specific interventions. Furthermore, although therapeutic strategies to control antibody‑induced damage remain limited, the longitudinal surveillance of dnDSA emergence and the clinical correlations of their characteristics will play a crucial role in the improvement of late kidney allograft survival.info:eu-repo/semantics/publishedVersio
Palliative approach in acute neurological events: a five-year study
Get PDFIntroduction: Acute neurological illness often results in severe disability. Five-year life expectancy is around 40%; half the survivors become completely dependent on outside help.
Objective: Evaluate the symptoms of patients admitted to a Hospital ward with a diagnosis of stroke, subarachnoid hemorrhage or subdural hematoma, and analyze the role of an In-Hospital Palliative Care Support Team.
Material and methods: Retrospective, observational study with a sample consisting of all patients admitted with acute neurological illness and with a guidance request made to the In-Hospital Palliative Care Support Team of a tertiary Hospital, over 5 years (2012-2016).
Results: A total of 66 patients were evaluated, with an age median of 83 years old. Amongst them, there were 41 ischaemic strokes, 12 intracranial bleedings, 12 subdural hematomas, and 5 subarachnoid hemorrhages. The median of delay between admission and guidance request was 14 days. On the first evaluation by the team, the GCS score median was 6/15 and the Palliative Performance Scale (PPS) median 10%. Dysphagia (96.8%) and bronchorrhea (48.4%) were the most prevalent symptoms. A total of 56 patients had a feeding tube (84.8%), 33 had vital sign monitoring (50.0%), 24 were hypocoagulated (36.3%), 25 lacked opioid or anti-muscarinic therapy for symptom control (37,9%); 6 patients retained orotracheal intubation, which was removed. In-hospital mortality was 72.7% (n=48).
Discussion and conclusion: Patients were severely debilitated, in many cases futile interventions persisted, yet several were under-medicated for symptom control. The delay between admission and collaboration request was high. Due to the high morbidity associated with acute neurological illness, palliative care should always be timely provided.INTRODUÇÃO: Eventos neurológicos agudos resultam frequentemente em incapacidade grave que impede o doente de participar ativamente nas decisões do seu próprio tratamento. A sobrevida a cinco anos ronda os 40%; metade dos sobreviventes fica dependente de terceiros. Objetivo: Avaliar a sintomatologia de doentes internados com acidente vascular cerebral (AVC), hemorragia subarcnoideia (HSA) ou subdural (HSD) e analisar a intervenção de uma Equipe Intra-Hospitalar de Suporte em Cuidados Paliativos (EIHSCP).
MATERIAL E MÉTODOS: Estudo retrospetivo observacional dos doentes com diagnóstico principal de evento neurológico agudo com pedido de colaboração à EIHSCP, num hospital terciário, durante cinco anos (2012-2016).
RESULTADOS: Avaliados 66 doentes, com média de idade de 83 anos. Destacam-se 41 AVC isquêmicos, 12 hemorrágicos, 12 HSD e 5 HSA. A média da demora entre internamento e pedido de colaboração à EIHSCP foi de 14 dias. Na primeira observação, a média na escala de coma de Glasgow foi de 6/15 e na Palliative Performance Scale (PPS) foi de 10%. Disfagia (96,8%) e broncorreia (48,4%) foram os sintomas mais frequentes. A maioria dos doentes (56/66) mantinha sonda nasogástrica (84,8%); 33 encontravam-se em monitorização cardiorrespiratória (50,0%); 24 estavam sob hipocoagulação (36,3%); 25 necessitavam de opioide e antimuscarínico que não estavam prescritos (37,9%); seis tinham tubo orotraqueal, que foi retirado. A mortalidade intra-hospitalar foi de 72,7% (n=48).
DISCUSSÃO E CONCLUSÃO: Destaca-se o estado debilitado dos doentes; em muitos casos, intervenções fúteis persistiam, mas várias foram submedicadas para o controle dos sintomas. Verificou-se um tempo de espera elevado até o pedido de colaboração. Pela elevada morbilidade associada a esses eventos, cuidados paliativos diferenciados deveriam ser oferecidos no tempo adequadoinfo:eu-repo/semantics/publishedVersio
