ABSTRACT

INTRODUCTION: We aimed to assess the effectiveness and tolerability of dolutegravir (DTG), abacavir (ABC) and lamivudine (3TC) administered as branded STR (DTG/ABC/3TC) or as two separate pills (DTG and either branded ABC/3TC [DTG+(ABC/3TC)b] or generic ABC/3TC [DTG+(ABC/3TC)g]). METHODS: We included individuals from the multicentre cohort of the Spanish HIV/AIDS Research Network (CoRIS) who received DTG/ABC/3TC, DTG+(ABC/3TC)b or DTG+(ABC/3TC)g during 2015 to 2018. We used multivariable logistic regression to compare the proportion of antiretroviral-naïve individuals who achieved viral suppression (VS) (viral load ≤50 copies/mL) at 24 weeks of initiating with DTG+(ABC/3TC)b or DTG+(ABC/3TC)g versus DTG/ABC/3TC. We also calculated the proportion of virologically suppressed individuals who maintained VS at 24 weeks after switching from DTG/ABC/3TC to DTG+(ABC/3TC)g. RESULTS: During the study period, 829, 68 and 47 treatment-naïve individuals started treatment with DTG/ABC/3TC, DTG+(ABC/3TC)b or DTG+(ABC/3TC)g respectively. The proportions of individuals who changed their regimens due to side effects during the first 24 weeks were 3.7%, 4.4% and 6.4% respectively (p = 0.646). We did not find significant differences in VS at 24 weeks among individuals starting with DTG+(ABC/3TC)b or DTG+(ABC/3TC)g compared to those initiating with DTG/ABC/3TC. Among 177 virologically suppressed individuals who switched from DTG/ABC/3TC to DTG+(ABC/3TC)g, 170 (96.0%) maintained VS at 24 weeks. CONCLUSIONS: In naïve individuals, the effectiveness and tolerability at 24 weeks of DTG plus ABC/3TC administered as two separate pills, either as branded or generic ABC/3TC, was similar to the STR DTG/ABC/3TC. Switching the STR DTG/ABC/3TC to its separate components DTG+(ABC/3TC)g in virologically suppressed individuals did not seem to impair its effectiveness.

ABSTRACT

Isolated neurosarcoidosis is a very rare disease, which makes up 5-15% of sarcoidosis cases. Hydrocephalus is a rare clinical feature with a prevalence of 6% among these patients. Considering neurosarcoidosis in the differential diagnosis of a unique parenquimal mass lesion could help in the early identification of this disease. We report the case of a 27-year-old African man who developed with a sole intracranial mass lesion mimicking radiologically a glioma, which finally came out as an isolated neurosarcoidosis. There is a difficulty in diagnosis when isolated neurosarcoidosis appears. In addition, the low prevalence of the disease entails a not standardized medical treatment. Natural outcome is poor even when hydrocephalus is resolved. Multimodal treatments including complete pharmacological treatment do not seem to assure a better outcome in these patients until date


La neurosarcoidosis cerebral aislada es una enfermedad muy rara, que representa entre el 5-15% de los casos de sarcoidosis. La hidrocefalia es una característica clínica poco frecuente, con una prevalencia del 6% entre estos pacientes. Considerar la neurosarcoidosis en el diagnóstico diferencial de una lesión de tipo masa parenquimatosa única puede ayudar en la identificación temprana de esta enfermedad. Presentamos el caso de un varón africano de 27 años de edad, que presenta una lesión de tipo masa única intracraneal que simulaba radiológicamente un glioma, y que finalmente se reveló como una neurosarcoidosis aislada. Es difícil establecer un diagnóstico cuando aparece una neurosarcoidosis cerebral aislada. Además, la baja prevalencia de la enfermedad conlleva un tratamiento médico no estandarizado. El pronóstico natural es malo, incluso cuando se resuelve la hidrocefalia. Hasta la fecha, los tratamientos multimodales, incluido el tratamiento farmacológico completo, no parecen asegurar un mejor resultado en estos pacientes

ABSTRACT

OBJECTIVES: To assess the attitudes and opinions about generic antiretroviral drugs (ARVs) and single-tablet regimen (STR) de-simplification among physicians prescribing HIV treatment in the cohort of the Spanish HIV/AIDS Research Network (CoRIS). METHODS: An online questionnaire with 27 structured questions was sent to all physicians (n=199) who prescribed ARVs among the 45 centres participating in the cohort. RESULTS: A total of 169 (84.9%) physicians answered the questionnaire. Only 4.1% of the physicians would never prescribe generic ARVs, but 53.3% would not prescribe them if the number of pills per day increased and 89.3% would not prescribe them if the number of doses per day increased. However, 84.0% of the physicians agreed to prescribe generic ARVs if doing so would decrease costs for the public healthcare system. The percentages of physicians stating that generic ARVs (compared with branded ones) would be associated with worse adherence, more adverse effects or more probability of virological failure, provided that the number of pills and doses per day would not change, were low: 0.6%, 7.7% and 3.6%, respectively. However, these percentages were much higher if the generic ARV entailed breaking an STR: 63.9%, 18.9% and 42.0%, respectively. Most physicians stated that they needed more information about the effectiveness and safety of generic ARVs and the price difference compared with their branded equivalents. CONCLUSIONS: Although most physicians were confident about prescribing generic ARVs, the majority had strong concerns about de-simplifying STR, and they also needed more information about generic drugs.

ABSTRACT

The online community resource Phytophthora database (PD) was developed to support accurate and rapid identification of Phytophthora and to help characterize and catalog the diversity and evolutionary relationships within the genus. Since its release in 2008, the sequence database has grown to cover 1 to 12 loci for ≈2,600 isolates (representing 138 described and provisional species). Sequences of multiple mitochondrial loci were added to complement nuclear loci-based phylogenetic analyses and diagnostic tool development. Key characteristics of most newly described and provisional species have been summarized. Other additions to improve the PD functionality include: (i) geographic information system tools that enable users to visualize the geographic origins of chosen isolates on a global-scale map, (ii) a tool for comparing genetic similarity between isolates via microsatellite markers to support population genetic studies, (iii) a comprehensive review of molecular diagnostics tools and relevant references, (iv) sequence alignments used to develop polymerase chain reaction-based diagnostics tools to support their utilization and new diagnostic tool development, and (v) an online community forum for sharing and preserving experience and knowledge accumulated in the global Phytophthora community. Here we present how these improvements can support users and discuss the PD's future direction.

ABSTRACT

Phytophthora ramorum, the causal agent of sudden oak death and ramorum blight, is known to exist as three distinct clonal lineages which can only be distinguished by performing molecular marker-based analyses. However, in the recent literature there exists no consensus on naming of these lineages. Here we propose a system for naming clonal lineages of P. ramorum based on a consensus established by the P. ramorum research community. Clonal lineages are named with a two letter identifier for the continent on which they were first found (e.g., NA = North America; EU = Europe) followed by a number indicating order of appearance. Clonal lineages known to date are designated NA1 (mating type: A2; distribution: North America; environment: forest and nurseries), NA2 (A2; North America; nurseries), and EU1 (predominantly A1, rarely A2; Europe and North America; nurseries and gardens). It is expected that novel lineages or new variants within the existing three clonal lineages could in time emerge.

ABSTRACT

El propósito de nuestro trabajo fue valorar la utilidad de la citología exfoliativa para confirmar la sospecha clínica del cáncer cutáneo no melanoma, determinando la sensibilidad y especificidad de ésta en el diagnóstico, corroborando los resultados con histopatología. La población la constituyeron los pacientes mayores de 16 años, ambos sexos, que concurrieron a nuestra sección Oncológica Cutánea en el curso del año 2000. Se utilizó la técnica de raspado con hoja de bisturí estéril, directamente sobre la superficie tumoral. Las lesiones intervenidas quirúrgicamente se analizaron histológicamente, con procedimiento de rutina, y ambos se observaron con microscopía óptica. Se utilizó para el tratamiento de los datos obtenidos el test de Discriminancia, que mide la sensibilidad y especificidad del método. Se realizaron 92 citologías, 70 fueron comparadas con el diagnóstico clínico y 22 con clínica e histopatología, obteniendo una tasa de sensibilidad del 88 por ciento y de especificidad del 50 por ciento. En coincidencia con la experiencia previa sobre el tema, concluimos que la citología exfoliativa es un método fácil, rápido y de bajo costo para el diagnóstico del cáncer cutáneo no melanoma
