RESUMO
BACKGROUND AND OBJECTIVES: Bexarotene has been approved to treat advanced stage cutaneous T-cell lymphomas (CTCL) since 1999. However, very few data have been published on its long-term safety and efficacy profile. The aim of this study is to determine the tolerability to bexarotene and outcomes by collecting the 2nd largest case series to date on its long-term use vs CTCL. MATERIAL AND METHOD: This was a multicenter retrospective review of 216 patients with mycosis fungoides (174), or Sézary syndrome (42) on a 10-year course of bexarotene alone or in combination with other therapies at 19 tertiary referral teaching hospitals. RESULTS: A total of 133 men (62%) and 83 women (38%) were included, with a mean age of 63.5 year (27-95). A total of 45% were on bexarotene monotherapy for the entire study period, 22% started on bexarotene but eventually received an additional therapy, 13% were on another treatment but eventually received bexarotene while the remaining 20% received a combination therapy since the beginning. The median course of treatment was 20.78 months (1-114); and the overall response rate, 70.3%. Complete and partial response rates were achieved in 26% and 45% of the patients, respectively. Treatment was well tolerated, being the most common toxicities hypertriglyceridemia (79%), hypercholesterolemia (71%), and hypothyroidism (52%). No treatment-related grade 5 adverse events were reported. CONCLUSIONS: Our study confirms bexarotene is a safe and effective therapy for the long-term treatment of CTCL.

Background Low-dose rituximab is a protocol used in several autoimmune diseases, that has also shown to be effective and safe in pemphigus vulgaris. Objectives To study whether low-dose rituximab is also effective for bullous pemphigoid. Methods Patients with BP were treated with a single cycle of two infusions of rituximab 500 mg at an interval of 2 weeks. Early and late end points were monitored. Results Six patients, five males and a female, with a mean age of 78.6 years (range 6589) and a mean history of BP of 6.7 months (range 216) were included. A rapid and marked response was observed after a single cycle of treatment, with a mean time to disease control and to end of consolidation phase of 1.9 (range 13), and 4 weeks (range 35), respectively. Four patients achieved a late end point at a mean of 15.75 weeks (range 1320). Three of them achieved partial remission with no therapy (two patients) or with minimal therapy (one patient), and one of them achieved complete remission with no therapy. One patient has 6 weeks of clinical follow-up after rituximab administration. The remaining patient relapsed 4 weeks after the rituximab treatment, and remains in complete remission with more than minimal therapy. One patient had a herpetic gingivostomatitis related to rituximab. Conclusions Low-dose rituximab for BP achieved acceptable remission rates and steroid-sparing activity, with a better safety profile and a lower cost, compared to standard doses. This pilot study suggests that low-dose rituximab could be a therapeutic option for BP (AU)
Antecedentes La administración de dosis bajas de rituximab es un protocolo utilizado en diversas enfermedades autoinmunes, que ha demostrado también su eficacia y seguridad para el pénfigo vulgar. Objetivos Determinar si rituximab a dosis bajas es efectivo para el penfigoide ampolloso (PA). Métodos Se trató a los pacientes con PA con un ciclo único de 2 infusiones de rituximab 500 mg con un intervalo de 2 semanas. Se monitorizaron los puntos temprano y final tardío. Resultados Se incluyeron en el estudio 6 pacientes, 5 varones y una mujer, con una edad media de 78,6 años (rango: 65.89) e historia media de PA de 6,7 meses (rango: 2-16). Se observó una respuesta rápida y acusada tras un ciclo único de tratamiento, con un tiempo medio hasta el control de la enfermedad y el final de la fase de consolidación de 1,9 (rango: 1-3) y 4 semanas (rango: 3-5), respectivamente. Cuatro pacientes lograron un punto final tardío a una media de 15,75 semanas (rango: 13-20). Tres de ellos lograron una remisión parcial sin terapia (2 pacientes) o con terapia mínima (un paciente), logrando uno de ellos la remisión completa sin terapia. A un paciente se le realizó un seguimiento de 6 semanas tras la administración de rituximab. El paciente restante sufrió una recaída transcurridas 4 semanas del tratamiento de rituximab, permaneciendo en remisión completa con terapia mínima. Un paciente manifestó gingivoestomatitis herpética relacionada con rituximab. Conclusiones La administración de dosis bajas de rituximab para PA logró tasas de remisión aceptables y reducción de esteroides, con un mejor perfil de seguridad y un menor coste, en comparación con las dosis estándar. Este estudio piloto sugiere que la administración de bajas dosis de rituximab podría ser una opción terapéutica para el PA (AU)

COVID-19 is an infectious disease caused by severe acute respiratory coronavirus 2 (SARS-CoV-2). Vesicular skin rashes have been reported as associated with COVID-19, but there is little information about this cutaneous manifestation. We designed a prospective observational study of patients diagnosed with COVID-19 who had vesicular lesions. Clinical characterization of skin findings was conducted by dermatologists. When possible, histological analysis and detection of SARS-CoV-2 in the content of the vesicles was performed. In total, 24 patients were included. A disseminated pattern was found in 18 patients (75%), and a localized pattern was found in 6 (25%). Median duration of the skin rash was 10 days. Of the 24 patients, 19 (79.2%) developed the skin rash after the onset of COVID-19 symptoms. Histological examination in two patients was consistent with viral infection, SARS-CoV-2 was not detected in four patients. This single-centre study shows the clinical characteristics of vesicular skin rashes in patients with COVID-19.

OBJECTIVE: Seasonal variation may occur in many different diseases hence influencing awareness in clinical practice. This study aimed to establish seasonal variations of acute pancreatitis by using a validated chronobiological analysis. PATIENTS AND METHODS: All cases of acute pancreatitis consecutively observed in fifteen years, i.e., from January 2003 to December 2017, at St. Anna University Hospital of Ferrara, Italy, were included in this study. Accurate statistical and logistic regression analyses were applied to our database. RESULTS: A total number of 1883 consecutive cases of acute pancreatitis were observed. A significant peak was identified in the summer period (p=0.014). Patient stratification, according to age, showed that elderly people had an increased incidence of acute pancreatitis in autumn and summer (being the biliary stone disease the main cause, p=0.011) vs. other seasons (p=0.003). Mortality occurred more prominently in males vs. females, although the latter gender was more prone to acute pancreatitis (p=0.017). CONCLUSIONS: In a single centre of Northern East of Italy, we demonstrated that acute pancreatitis had a clear seasonal variation with a prominent incidence during summer. Various associated factors could contribute to this chronobiological pattern, including gender, age, and biliary stone disease.

BACKGROUND: Xeroderma pigmentosum (XP) is a very rare and severe genetic disorder with a DNA repair defect of ultraviolet (UV)-induced damage. Photodynamic therapy (PDT) has been successfully used in XP patients to treat actinic keratosis (AK) and daylight PDT (DL-PDT) has demonstrated similar efficacy to conventional PDT (C-PDT) for AK. OBJECTIVES: To assess DL-PDT for the treatment of AK in patients with XP. METHODS: Patients with XP were evaluated by a group of Spanish and African dermatologists. Clinical characteristics of the patients were assessed and divided in mild, severe or moderate affectation of AK in the face. A topical photosensitizer was extended on the patients' faces and after two hours of indoor light exposure, fluorescence was assessed and the cream was removed. Patients were examined two and seven days later to assess the reaction to PDT and followed up three months later. RESULTS: A total of 13 patients were treated on the whole face. Three were classified as severe AK, six as moderate AK and four as mild AK. Fluorescence assessment showed a soft yellow-green colour and a pink-color delineating the AK. Two days after treatment patients presented a scaly reaction. After one week the reaction healed, there was improvement and after three months no adverse events were noticed. CONCLUSIONS: PDT is an option for treatment of AK in patients with XP.
