Desarrollo de formulaciones de liberación controlada para enfermedades inflamatorias
2022
Las enfermedades inflamatorias con componente autoinmune de la piel y del tracto gastrointestinal, como son la psoriasis y la dermatitis atópica y la enfermedad inflamatoria intestinal, respectivamente, son enfermedades prevalentes que necesitan mejorar su tratamiento. La ciclosporina A es un fármaco inmunosupresor que ha demostrado ser efectivo para el tratamiento de enfermedades autoinmunes, pero también sus efectos adversos a nivel sistémico. En el caso de las enfermedades cutáneas, la administración por vía tópica de este fármaco aportaría grandes ventajas como la posibilidad de actuar a nivel local y evitar efectos sistémicos. Sin embargo, la ciclosporina A presenta un tamaño molecular…
Treatment Persistence and Safety of Apremilast in Psoriasis: Experience With 30 Patients in Routine Clinical Practice
2020
Apremilast is a phosphodiesterase-4 inhibitor taken orally. Little information about its use in routine clinical practice is available. We aimed to assess treatment safety and persistence rates in patients on apremilast for different forms of plaque psoriasis. This observational retrospective study included 30 patients with psoriasis who were treated with apremilast between January 2016 and December 2017 in our hospital. Twelve patients had palmar-plantar psoriasis, 8 had plaque psoriasis mainly on the scalp, and 10 had plaque psoriasis in other locations. The probable period of treatment persistence in patients in the 50th percentile was 18.5 months according to survival analysis of the se…
Geographic stomatitis: An enigmatic condition with multiple clinical presentations
2019
Geographic stomatitis is an uncommon inflammatory condition of unknown etiology. It is characterized by reddish areas surrounded by white borders affecting any location in the oral cavity and presenting a migratory and cyclic pattern. The most common affected sites include buccal mucosa, labial mucosa and mucobuccal fold. Some patients can complain of pain or burning sensation. There are few reports in the literature about this entity and its relationship with other oral and cutaneous conditions such as fissured tongue, Reiter's syndrome, atopy and psoriasis has been suggested but it is still controversial. In the present study we describe three cases of geographic stomatitis associated wit…
Advances in antioxidant phytochemical for inflammatory skin diseases: mangiferin and naringin nanocarriers based lipids
2020
Chronic inflammatory skin diseases are the most common topical disorders and the fourth cause of global disability. Among all, psoriasis (PS) and atopic dermatitis (AD) are the most frequent chronic and recurrent inflammatory diseases of the skin. Atopic dermatitis has a strong Th2 factor while psoriasis is a disease driven by Th17. The actual treatment, which involve the combination of topical, systemic and biological therapy, is characterized by numerous adverse effects, which reduce patient compliance, lead to the limitation of long-term use and limit the therapeutic efficacy. Therefore, there is a great need for the continuous development of novel, effective and safe coadjuvant treatmen…
Effectiveness of cyclosporine A in patients with moderate to severe plaque psoriasis in a real-life clinical setting in Italy: the TRANSITION study
2020
Background: Cyclosporine A (CsA) is one of the systemic therapeutic options for moderate-to-severe psoriasis, based on its efficacy and rapidity of action. The current study investigated the response to CsA in patients with moderate-to-severe plaque psoriasis. Materials and Methods: TRANSITION was an observational, cross-sectional, multicentre study which evaluated the proportion of partial- and suboptimal-responders among patients with moderate-to-severe plaque psoriasis treated with continuous CsA for >= 12 weeks. Patients demonstrating a Psoriasis Area and Severity Index (PASI) response of >= 90, >= 75 and <90, >= 50 and <75 and <50 were defined as responders, subopt…
Separation of deoxyribonucleases (DNases) of normal human stratum corneum and psoriatic scales by micro-disc-electrophoresis.
1975
Normal stratum corneum and psoriatic scales were homogenized and a differential centrifugation was performed. The DNase activity of the individual fractions was investigated by micro-disc-electrophoresis. At pH 5 only in the 600 × g pellet and 105.000 × g supernatant of normal keratin DNase activity could be observed. However, all psoriatic fractions showed distinct enzyme activities. At pH 7.4 little psoriatic DNase activity could only be demonstrated in the 105.000 × g supernatant. Except from the 15.000 × g pellet all fractions of normal stratum corneum displayed marked activities. In addition the 105.000 × g supernatant showed two different DNase bands.
Mangiferin glycethosomes as a new potential adjuvant for the treatment of psoriasis
2020
[EN] Mangiferin, a natural compound isolated from Mangifera indica L, was incorporated in glycerosomes, ethosomes and alternatively in glycerol-ethanol phospholipid vesicles (glycethosomes). Actually, only glycethosomes were able to stably incorporate the mangiferin that was loaded at increasing concentrations (2, 4, 6, 8 mg/mL). The morphology, size distribution, rheological properties, surface charge and entrapment efficiency of prepared vesicles were deeply measured. All vesicles were mainly spherical, oligolamellar, small in size (similar to 145 nm) and negatively charged (similar to-40 mV), as confirmed by cryo-TEM observation and dynamic laser light scattering measurements. The higher…
Psoriasis moderada-grave en pacientes pediátricos y jóvenes: experiencia en el registro BIOBADADERM
2022
Resumen {0>El debut de la psoriasis en la edad pediatrica, aunque generalmente leve, puede requerir tratamiento sistemico en las formas moderadas o graves de la enfermedad. Childhood-onset psoriasis generally follows an indolent course but patients with moderate or severe disease may require systemic treatment. El objetivo de este trabajo es analizar la frecuencia relativa, las caracteristicas de los pacientes, el tratamiento empleado y los eventos adversos (EA) observados a partir del registro BIOBADADERM en ninos y jovenes con psoriasis moderada-grave. The aim of this study was to determine the relative proportion of children and young people aged up to 21 years with moderate to severe ps…
Nuevas perspectivas en el abordaje terapéutico de la psoriasis
2014
En la actualidad las enfermedades inflamatorias crónicas de la piel, como la psoriasis, tienen un impacto significativo en cuanto a la calidad de vida de los pacientes y sus familias, además de representar una carga económica considerable. Se estima que aproximadamente el 3% de la población mundial sufre psoriasis. Esta patología presenta tres componentes característicos: un desequilibrio entre la respuesta inmune local y sus mecanismos reguladores, una respuesta inflamatoria exagerada y una renovación epidérmica incrementada. A pesar del efecto beneficioso que ha supuesto la introducción de las nuevas aunque costosas terapias biológicas en el tratamiento sistémico de la psoriasis, el metot…
Changing Trends in Drug Prescription and Causes of Treatment Discontinuation of First Biologic Over Ten Years in Psoriasis in the Spanish Biobadaderm…
2020
Background and objectives: Current psoriasis guidelines do not usually include recommendations about first line classical or biologic treatment. The objectives of this study were: to describe shifts in the prescription of the first biological treatment, and to compare treatment withdrawal and rates of adverse events over ten years. Material and methods: Biobadaderm registry was analyzed to describe: first biological prescription in bio-naive patients, adverse events rate and reasons for drug withdrawal comparing three periods of time (2008-2010, 2011-2014, 2015-2018). Results: Anti-TNF drugs were the most prescribed biological drug from 2008 to 2010. Ustekinumab has become the most prescrib…
