Evaluation of rapid antiretroviral initiation strategy in a cohort of newly diagnosed people living with HIV in Panama, 2018-2019.

Antiretroviral therapy (ART) has been adopted as a form of HIV treatment and prevention. This study assesses rapid ART initiation using clinical outcomes such as viral load (VL) and CD4+ T lymphocytes count. Over the course of one year, the progress of newly diagnosed people living with HIV who started ART early in a hospital in Panama City was followed. The evaluation of early initiation of ART in achieving viral suppression (VL <200 copies/ml) was analyzed using descriptive statistics. Additionally, the cost difference between early (first 7 days) and late initiation of ART was evaluated from the perspective of the service provider. In total, 209 people were followed up during the study; 85% were male, 70% started ART on same day from hospital arrival, 80% had suppressed viral load at 6 months, and the median count of CD4 increased from 285 (IQR: 166-429) to 509 (IQR: 373-696) over 12 months. Starting ART early led to a 42% increase for the provider in terms of staffing costs; however, the clients had the opportunity to decrease absenteeism in daily activities. The results reveal that early initiation of ART generates clinical and economic benefits for the person in treatment.

Etiopathogenesis of chronic kidney disease-associated pruritus: putting the pieces of the puzzle together.

Defined as the unpleasant sensation that causes the desire to scratch, pruritus is the most common skin symptom associated with uremia and appears in almost half of patients with advanced chronic kidney disease (CKD). Beyond its direct impact on quality of life, CKD-associated pruritus (CKD-aP) is an independent predictor of mortality that also has a synergistic effect with other quality of life-related symptoms, such as insomnia, depression, and anxiety. Although different mechanisms have been proposed to explain the origin of Pa-ERC, its etiopathogenesis is still not fully understood. Since new therapeutic targets have been identified and several clinical trials have recently shown promising results, our current understanding of the interrelationships has expanded significantly and the pathophysiological mechanisms underlying CKD-aP are now considered to be multifactorial. The potential triggers of pruritus in patients with CKD are discussed in this review, including hypotheses about skin xerosis, accumulation of uremic toxins, dysregulation of the immune system and systemic inflammation, uremic neuropathy, and imbalances in the endogenous opioid system. Other non-uremic causes of pruritus are also discussed, with the aim of guiding the physicians to apply an adequate aetiopathogenic approach to CKD-aP in their day-to-day clinical practice.

Perception of Spanish nephrologists on an old unsolved problem: Pruritus associated with chronic kidney disease (CKD-aP).

INTRODUCTION: Pruritus associated with chronic kidney disease is defined as the sensation of itching, in people with chronic kidney disease, in a one area or all over the body that causes the need to scratch, after having ruled out other dermatological or systemic causes. It is an old and known problem whose prevalence has been able to decrease with the improvement of dialytic techniques but which still persists and is underdiagnosed. OBJECTIVES: The objective of this study was to analyse the current perception of nephrologists about this problem that influences the quality of life of people with chronic kidney disease through a survey. RESULTS: 135 nephrologists, most of them engaged in haemodialysis, participated. 86% considered that pruritus associated with chronic kidney disease is still a problem today that affects the quality of life. Most nephrologists believe that the main pathophysiological cause is uremic toxins (60%) and only 16% believe that it is due to the dysregulation of the opioid system/endorphins-dynorphins. Only 16% comment that the prevalence of pruritus in their centre is greater than 20%. 40% believe that the diagnosis is made because it is manifested by the patient and only 27% because it is asked by the doctor. Moreover, it is not usual to use scales to measure it or the codification in the medical records. The main treatment used is antihistamines (96%), followed by moisturizers/anaesthetics (93%) and modification of the dialysis regimen (70%). CONCLUSIONS: Pruritus associated with chronic kidney disease is still a current problem, it is underdiagnosed, not codified and with a lack of indicated, effective and safe treatments. Nephrologists do not know its real prevalence and the different pathophysiological mechanisms involved in its development. Many therapeutic options are used with very variable results, ignoring their efficacy and applicability at the present time. The new emerging kappa-opioid-receptor agonist agents offer us an opportunity to reevaluate this age-old problem and improve the quality of life for our patients with chronic kidney disease.

Etiopatogenia del prurito asociado a la enfermedad renal crónica: recomponiendo las piezas del puzle / Etiopathogenesis of chronic kidney disease-associated pruritus: Putting the pieces of the puzzle together

Definido como la sensación desagradable que provoca el deseo de rascarse, el prurito es el síntoma cutáneo más frecuente asociado a la uremia, pudiendo aparecer en casi la mitad de los pacientes con enfermedad renal crónica (ERC) avanzada. Más allá de su repercusión directa sobre la calidad de vida, el prurito asociado a la ERC (Pa-ERC) es un predictor independiente de mortalidad que además ejerce un efecto sinérgico con otros síntomas también relacionados con la calidad de vida, como la depresión y el insomnio. Aunque se han propuesto diferentes mecanismos para explicar su origen, la etiopatogenia del Pa-ERC sigue sin conocerse por completo. Dado que se han identificado nuevas dianas terapéuticas y recientemente varios ensayos clínicos han mostrado resultados prometedores, nuestra comprensión actual de las interrelaciones se ha ampliado significativamente, considerando multifactoriales los mecanismos fisiopatológicos subyacentes al Pa-ERC. En la presente revisión se discuten los potenciales factores desencadenantes de prurito en el paciente con ERC, incluyendo las hipótesis sobre la xerosis cutánea, el acúmulo de toxinas urémicas, la desregulación del sistema inmune y la inflamación sistémica, la neuropatía urémica y los desequilibrios en el sistema opioide endógeno, así como otras causas no urémicas de prurito, con el objetivo de orientar al clínico para realizar un adecuado abordaje etiopatogénico del Pa-ERC en su día a día.

Percepción de los nefrólogos españoles sobre un problema antiguo no resuelto: Prurito asociado a la enfermedad renal crónica (Pa-ERC) / Perception of Spanish nephrologists on an old unsolved problem: Pruritus associated with chronic kidney disease (CKD-aP)

Introducción: El prurito asociado a enfermedad renal crónica se define como la sensación desagradable que provoca la necesidad de rascarse en una parte del cuerpo o en todo en personas con enfermedad renal crónica, tras haberse descartado otras causas dermatológicas o sistémicas. Es un problema antiguo y conocido cuya prevalencia ha podido disminuir con la mejoría de la eficacia dialítica pero que todavía persiste y está infradiagnosticado. Objetivos: El objetivo de este estudio fue analizar la percepción y práctica actual de los nefrólogos sobre este problema que impacta en la calidad de vida de las personas con enfermedad renal crónica a través de una encuesta anónima. Resultados: Participaron 135 nefrólogos, la mayoría dedicados a hemodiálisis. Un 86% consideró que el prurito asociado a enfermedad renal crónica sigue siendo un problema en la actualidad que afecta a la calidad de vida. La mayoría de los nefrólogos opinan que la principal causa fisiopatológica son las toxinas urémicas (60%) y solo un 16% cree que se debe a la desregulación del sistema opioide/endorfinas-dinorfinas. Únicamente un 16% comenta que la prevalencia de prurito en su centro es mayor del 20%. Un 40% cree que el diagnóstico se realiza porque lo manifiesta el paciente y solo un 27% porque lo pregunta el facultativo. Además, no es habitual usar escalas ni codificarlo en la historia clínica. El tratamiento más común son los antihistamínicos (96%), seguido de las cremas hidratantes/anestésicas (93%) y la modificación de la pauta de diálisis (70%). (AU)

Use of Project ECHO in Response to COVID-19 in Countries Supported by US President's Emergency Plan for AIDS Relief.

The US Centers for Disease Control and Prevention, with funding from the US President's Plan for Emergency Relief, implements a virtual model for clinical mentorship, Project Extension for Community Healthcare Outcomes (ECHO), worldwide to connect multidisciplinary teams of healthcare workers (HCWs) with specialists to build capacity to respond to the HIV epidemic. The emergence of and quick evolution of the COVID-19 pandemic created the need and opportunity for the use of the Project ECHO model to help address the knowledge requirements of HCW responding to COVID-19 while maintaining HCW safety through social distancing. We describe the implementation experiences of Project ECHO in 5 Centers for Disease Control and Prevention programs as part of their COVID-19 response, in which existing platforms were used to rapidly disseminate relevant, up-to-date COVID-19-related clinical information to a large, multidisciplinary audience of stakeholders within their healthcare systems.

Danazol as First-Line Therapy for Myelodysplastic Syndrome.

BACKGROUND: Allogeneic stem cell transplantation (ASCT) represents the only option with a potential cure rate of 30% to 50% in myelodysplastic syndrome (MDS); however, < 5% of patients are optimal candidates for this management. Therapeutic options are limited in patients unsuitable for ASCT. Evidence that androgens might be beneficial in MDS is controversial. We aimed to document the clinical outcomes of patients diagnosed with MDS treated with danazol as first-line therapy. PATIENTS AND METHODS: We retrospectively reviewed patients diagnosed in our center with MDS according to the World Health Organization 2008 criteria and treated with danazol between 2005 and 2015. Response was defined according to international working group criteria. RESULTS: We included 42 patients treated exclusively with danazol. Median dose was 400 mg/d (range, 100-600 mg/d). Median follow-up was 12 (range, 3-76) months. Twenty-four of these patients (60%) achieved clinical response. Median overall survival was 24 months (95% confidence interval, 5.1-42). Responders were older than nonresponders (P = .025) and had higher baseline hemoglobin concentration (P = .009). No patients discontinued danazol because of toxicity. Fifteen patients died (35.7%) and 5 progressed to acute myeloid leukemia. CONCLUSION: Danazol as first-line therapy is an acceptable treatment option with low side effects for patients with MDS who cannot receive ASCT.
