Fast and sustained improvement of patient-reported outcomes in psoriatic patients treated with secukinumab in a daily practice setting.

Psoriasis is a chronic dermatological disease with great impact on patients' quality of life (QoL). The main objective of this study was to assess the impact of secukinumab treatment on different patient-reported outcomes (PROs) during a long-term follow-up in Spanish patients with moderate-to-severe psoriasis under real-world conditions. Retrospective, observational, open-label, nationwide multicenter cohort study that included patients who initiated treatment with secukinumab in daily clinical practice conditions. PROs assessing disease impact and QoL included Dermatology Life Quality Index (DLQI), Patient's Global Psoriasis Assessment, Itch Numerical Rating Scale and EuroQoL Thermometer Visual Analogue Scale. Outcomes, including PROs and Psoriasis Area and Severity Index (PASI), were assessed at months 3, 6, 12, 18, and 24 during treatment. A total of 238 patients were enrolled in the study. Patients had a mean DLQI score of 14.9 at baseline; 78.3%, 73.7%, and 71.7% of them achieved a DLQI 0/1 response at months 6, 12, and 24, respectively. DLQI score was lower in the long term for naïve patients. A sharp decrease in mean DLQI was observed during the first 3 months, reaching a plateau that was maintained until the end of follow-up. Similar findings were observed for the rest of QoL assessments. There was a close association between improvement in QoL and skin clearance (PASI), which progressively increased during follow-up. In this study, secukinumab sustainably improved patient's QoL during a 24-month follow-up, with strongest effects in patients naïve to biological therapies and with a direct correlation with PASI improvement.

Secukinumab is effective and safe in the long-term treatment of plaque psoriasis in a daily practice setting: Multicenter study in 384 Spanish patients.

The aim of the study was to assess the long-term effectiveness and safety of secukinumab in Spanish patients with moderate-to-severe psoriasis in a daily practice setting. Nationwide multicenter, observational, retrospective, non-interventional, single-cohort study including patients who initiated treatment with secukinumab in daily clinical practice conditions. Subjects were followed for a minimum of 3 months and a maximum of 24 months. Psoriasis Area Severity Index (PASI), Body Surface Area and Physician's Global Assessments were collected at baseline and months 3, 6, 12, 18 and 24 during treatment. Adverse events and reasons for secukinumab withdrawal were collected and classified for analyses. A total of 384 patients were enrolled in the study. Median PASI declined rapidly from 14.3 at baseline to 2.7 at month 3, 2.1 at month 12, and remained low (2.8) at month 24. Within the group of patients with PASI ≥10 at baseline (n = 278), 58.3%, 60.4% and 56.5% achieved a PASI90 response at months 3, 12 and 24, respectively. As for absolute PASI, 86.5%, 69.5%, 42.7% and 37% achieved PASI <5, < 3, < 1 and 0, respectively, at month 3. Secukinumab was more effective in biologic-naïve patients and in those with lower Body Mass Index. Secukinumab presented a good long-term safety profile. Secukinumab was effective and safe in a routine clinical setting, in a large cohort of patients with moderate-to-severe plaque psoriasis, in the short-, medium- and long-term (up to 24 months).

eDiVA-Classification and prioritization of pathogenic variants for clinical diagnostics.

Mendelian diseases have shown to be an and efficient model for connecting genotypes to phenotypes and for elucidating the function of genes. Whole-exome sequencing (WES) accelerated the study of rare Mendelian diseases in families, allowing for directly pinpointing rare causal mutations in genic regions without the need for linkage analysis. However, the low diagnostic rates of 20-30% reported for multiple WES disease studies point to the need for improved variant pathogenicity classification and causal variant prioritization methods. Here, we present the exome Disease Variant Analysis (eDiVA; http://ediva.crg.eu), an automated computational framework for identification of causal genetic variants (coding/splicing single-nucleotide variants and small insertions and deletions) for rare diseases using WES of families or parent-child trios. eDiVA combines next-generation sequencing data analysis, comprehensive functional annotation, and causal variant prioritization optimized for familial genetic disease studies. eDiVA features a machine learning-based variant pathogenicity predictor combining various genomic and evolutionary signatures. Clinical information, such as disease phenotype or mode of inheritance, is incorporated to improve the precision of the prioritization algorithm. Benchmarking against state-of-the-art competitors demonstrates that eDiVA consistently performed as a good or better than existing approach in terms of detection rate and precision. Moreover, we applied eDiVA to several familial disease cases to demonstrate its clinical applicability.

Severe neurocognitive and growth disorders due to variation in THOC2, an essential component of nuclear mRNA export machinery.

Highly conserved TREX-mediated mRNA export is emerging as a key pathway in neuronal development and differentiation. TREX subunit variants cause neurodevelopmental disorders (NDDs) by interfering with mRNA export from the cell nucleus to the cytoplasm. Previously we implicated four missense variants in the X-linked THOC2 gene in intellectual disability (ID). We now report an additional six affected individuals from five unrelated families with two de novo and three maternally inherited pathogenic or likely pathogenic variants in THOC2 extending the genotypic and phenotypic spectrum. These comprise three rare missense THOC2 variants that affect evolutionarily conserved amino acid residues and reduce protein stability and two with canonical splice-site THOC2 variants that result in C-terminally truncated THOC2 proteins. We present detailed clinical assessment and functional studies on a de novo variant in a female with an epileptic encephalopathy and discuss an additional four families with rare variants in THOC2 with supportive evidence for pathogenicity. Severe neurocognitive features, including movement and seizure disorders, were observed in this cohort. Taken together our data show that even subtle alterations to the canonical molecular pathways such as mRNA export, otherwise essential for cellular life, can be compatible with life, but lead to NDDs in humans.

A Narrative Review of Interhospital Transfers for Hemorrhagic Stroke.

Of the 750,000 strokes in the United States every year, about 15% patients suffer from hemorrhagic stroke (HS). Intracerebral hemorrhage (ICH) and aneurysmal subarachnoid hemorrhage (SAH) are subtypes of hemorrhagic stroke. Despite advances in acute management patients with hemorrhagic stroke continue to suffer from high mortality and while survivors suffer from multi-domain impairments in the physical, cognitive and mental health domains which can last for months to years from their index stroke. Long-term prognosis after HS is critically dependent on the quality and speed of care a patient receives during the acute phase of care. The frequency of IHT for hemorrhagic stroke is increasing. However, the associations between IHT and HS outcomes have not been well described in literature. In this review, we describe the epidemiology of IHT for HS, the relationship between IHT and HS patient outcomes, and proposed improvements to the IHT process to ensure better long-term patient outcomes. Our review indicates that evidence regarding the safety and benefit of IHT for HS patients is conflicting, with some studies reporting poorer outcomes for transferred patients compared to direct admissions via emergency rooms and others showing no effect on outcomes. IHT may, however, may prevent timely institution of clinical interventions such as blood pressure control and anticoagulant reversal. Large, prospective, and multi-center studies comparing outcomes of IHT patients to direct admissions are necessary to provide more definitive guidance to optimize IHT protocols and aid clinical decision-making.

Survival and Lung Function Changes in Hypersensitivity Pneumonitis According to Radiological Phenotypes Compared With Idiopathic Pulmonary Fibrosis.

INTRODUCTION: The main objective of this study was to estimate survival and changes in lung function in patients with chronic hypersensitivity pneumonitis (HP), both fibrotic (f-HP) and nonfibrotic (nf-HP), and to compare them with those in patients with idiopathic pulmonary fibrosis (IPF). METHODS: HP was diagnosed based on antigen exposure, HRCT (high-resolution CT scan), BAL (bronchoalveolar lavage), and histology. According to HRCT, HP was classified into fibrotic and non-fibrotic phenotypes. In most cases, IPF was diagnosed based on HRCT findings. RESULTS: We identified 84 patients: 46 with IPF, 18 with f-HP, and 20 with nf-HP. Five-year survival was 23.9% in IPF, 72% in f-HP, and 100% in nf-HP (p <0.0001). Honeycombing was associated with decreased survival in IPF (p <0.001) and in f-HP (p <0.0001). The mean loss of FVC (forced vital capacity) % pred. (percent predicted) was -18.3% in IPF (p =0.001), -4.8% in f-HP, and -6.0% in nf-HP. The mean change in DLCO (diffusion capacity for carbon monoxide) % pred. was -10.2% in IPF (p <0.002), -0.5% in f-HP, and +1.9% in nf-HP. The agreement between radiological phenotypes and histology in HP was 89.6%. CONCLUSIONS: We found shorter survival in IPF, followed by f-HP, and nf-HP. Over time, we did not find significant changes in FVC% pred. or DLCO% pred. in HP, while a significant decline in IPF was noted. In HP, we found strong agreement between radiological phenotypes and histology. Radiological signs suggestive of lung fibrosis in HP were reliable for the diagnosis of f-HP and seem to have intrinsic prognostic value.

Dose reduction is a feasible strategy in patients with plaque psoriasis who achieve sustained response with secukinumab: a retrospective, multicenter cohort study in daily practice setting.

BACKGROUND: Biological therapy dose modification is a common practice in the long-term treatment of plaque psoriasis. OBJECTIVE: The objective of the study was to determine prevalence, characteristics of patients, effectiveness, treatment survival of secukinumab dose reduction (SEC-DR) strategy and assess its safety and cost implications. METHODS: A retrospective, observational, multicenter cohort study was conducted in patients with plaque psoriasis treated with secukinumab and up to 2 years of follow-up. RESULTS: In 63/347 patients with an initial standard dose regimen, SEC-DR was tried at any moment in 18.2% of them after sustained response. In 51 patients, the interval between administrations was increased while in 12 patients, monthly dose was reduced to 150 mg. Successful SEC-DR was achieved in 77.8% of the patients, with sustained PASI response to the end of the study. Survival of secukinumab treatment and safety profile were not compromised by DR. The use of DR saved 33% of the cost, including failures in which standard treatment was resumed. LIMITATIONS: The proper of the study designed and the arbitrary definition of "DR success." CONCLUSION: Off-label SEC-DR strategy was used in patients with sustained response to standard dose regimen; this strategy showed long-term efficacy without compromising treatment survival or worsening the safety profile while also being cost saving.

Target selection for deep brain stimulation in treatment resistant schizophrenia.

The use of deep brain stimulation (DBS) in treatment resistant patients with schizophrenia is of considerable current interest, but where to site the electrodes is challenging. This article reviews rationales for electrode placement in schizophrenia based on evidence for localized brain abnormality in the disorder and the targets that have been proposed and employed to date. The nucleus accumbens and the subgenual anterior cingulate cortex are of interest on the grounds that they are sites of potential pathologically increased brain activity in schizophrenia and so susceptible to the local inhibitory effects of DBS; both sites have been employed in trials of DBS in schizophrenia. Based on other lines of reasoning, the ventral tegmental area, the substantia nigra pars reticulata and the habenula have also been proposed and in some cases employed. The dorsolateral prefrontal cortex has not been suggested, probably reflecting evidence that it is underactive rather than overactive in schizophrenia. The hippocampus is also of theoretical interest but there is no clear functional imaging evidence that it shows overactivity in schizophrenia. On current evidence, the nucleus accumbens may represent the strongest candidate for DBS electrode placement in schizophrenia, with the substantia nigra pars reticulata also showing promise in a single case report; the ventral tegmental area is also of potential interest, though it remains untried.

Multicenter Retrospective Study of Secukinumab Drug Survival in Psoriasis Patients in a Daily Practice Setting: A Long-Term Experience in Spain.

INTRODUCTION: There is limited and conflicting evidence over the real-world drug survival of secukinumab (SEC) in patients with psoriasis, especially in the long term. Our objective was to analyze the short- and long-term survival of SEC (S-SEC) and its predictive factors for the treatment of psoriasis. METHODS:  Patients clinically diagnosed with plaque psoriasis and under treatment with secukinumab (n = 384) in a daily practice setting were analyzed in a retrospective, multicenter study performed in a nationwide cohort and followed up for a period of 2 years. Kaplan-Meier curve was plotted to analyze drug survival time, and log-rank test was performed to compare several groups. Factors related to speed of treatment discontinuation were studied with a Cox regression model. RESULTS: The overall cumulative secukinumab drug survival rates observed at 6, 12, 18, and 24 months were 97.1%, 89.0%, 81.1%, and 74.3%, respectively. Obesity [hazard ratio (HR), 1.809, CI 95% 1.114-2.962; p = 0.004] and previous experience with biological therapies, particularly those who had been treated with ≥ 2 biologicals with different mechanisms of action (HR 3.476, CI 95% 1.875-6.444; p = 0.017) were associated with an early discontinuation, whereas psoriatic arthritis was associated with delayed discontinuation, (HR 0.493, CI 95% 0.265-0.917; p = 0.025). CONCLUSIONS: In our study, we found that cumulative secukinumab drug survival for psoriasis patients for the period 6-18 months was in the range of real-world evidence studies. Additionally, we observed a relatively high long-term survival rate at 24 months (74.3%).

Safety and effectiveness of conventional systemic therapy and biological drugs in patients with moderate to severe psoriasis and HIV infection: a retrospective multicenter study.

Background: The management of HIV-positive patients with psoriasis is controversial and limited to individual cases or short series of patients. Objectives: To evaluate the safety and effectiveness of conventional and biologic immunosuppressive drugs in the treatment of patients with psoriasis and concomitant HIV infection. Methods: A retrospective multicenter study was conducted. The study included data from 2008 to 2016. Inclusion criteria were: HIV adult patients with moderate-to-severe psoriasis, HIV viral load determinations at baseline and at least after 6 months of treatment, and systemic immunosuppressive treatment for at least 6 months. A descriptive analysis was performed. Results: Twenty-three patients with plaque-type psoriasis and HIV infection (five with AIDS) were included. Median follow-up time was 3.2 years. The main drugs used were etanercept, methotrexate, and ustekinumab. In most cases, viral load and CD4 cell count not only remained stable but also improved throughout the follow-up. Six patients presented severe adverse events during the follow-up, four of them in the AIDS stage. At the end of the follow-up period, 76.5% of the patients had achieved a PASI 75. Conclusion: Biologic drugs, both anti-TNF alpha agents and ustekinumab, seem to have an acceptable safety profile and high effectiveness in HIV-positive patients.

Evaluación del sistema de vigilancia epidemiológica de la malaria en el Municipio de Tocoa, Colón, Honduras, Agosto 2004 / Evaluation of the malaria epidemiologic surveillance system in the District of Tocoa, Colon, Honduras, August 2004

ANTECEDENTES. El sistema de vigilancia epidemiológica de la malaria (SVEM) de Honduras inició en 1942. En la actualidad, aproximadamente el 80 de la población habita en zonas con algún riesgo de transmisión y el Municipio de Tocoa, Departamento de Colón, es uno de los municipios con mayor incidencia. OBJETIVO. Describir y evaluar el SVEM del Municipio de Tocoa. METODOLOGIA. En agosto 2004 se entrevistó a personal de la red de Colaboradores Voluntarios (Col.Vol.), del Área Municipal y del Hospital de Tocoa para investigar las características del SVEM. Se visitaron todas las Unidades de Salud (US,n= 12) y aleatoriamente se entrevistó 1-2 Col. Vol. de cada US. Se estimó el valor predictivo positivo (VPP) para 2001-2003 y se calcularon frecuencias y promedios de algunos atributos. RESULTADOS. El SVEM utiliza dos definiciones de caso y la información fluye por dos vías. Mediante indicadores detecta tendencias y evalúa impacto; determina ocurrencia de casos en tiempo, lugar y persona, con una aceptabilidad del 70. Pueden transcurrir hasta 37 días entre la toma de la muestra y el resultado. El VPP promedio fue de 19. Se carece de normas técnicas y material informativo. No existe una base de datos a nivel local y el análisis es realizado manualmente. CONCLUSIONES. Aunque el SVEM es moderadamente aceptable, flexible y representativo, tiene bajo VPP, el flujo de la información es complicado y no suministra información oportuna. El sistema debe ser fortalecido a través de la unificación de criterios y provisión de normas técnicas a todos los niveles...
