Dynamics of creatinine estimated glomerular filtration rate using one or more antiretrovirals that inhibit creatinine tubular secretion.

BACKGROUND: Cobicistat, dolutegravir and rilpivirine are all modest inhibitors of proximal tubular creatinine secretion (IPTCrS) and hence a moderate and early non-progressive creatinine estimated glomerular filtration rate (Cr-eGFR) reduction has been observed in clinical trials. Data regarding the impact of combination of those drugs on Cr-eGFR, in the clinical practice, are scarcely known. METHODS: Changes in Cr-eGFR after starting darunavir/cobicistat alone or in combination with dolutegravir and/or rilpivirine were studied in a nationwide retrospective cohort study of consecutive HIV-infected patients initiating darunavir/cobicistat. The relationship between Cr-eGFR changes over time and the use of darunavir/cobicistat alone or darunavir/cobicistat plus dolutegravir and/or rilpivirine adjusted by different HIV patient's characteristics, socio-demographics, HIV severity and use of tenofovir concomitant medication other than antiretrovirals was explored through univariate and multivariate analyses. RESULTS: The analysis included 725 patients. At 48 weeks, the combination of two or more IPTCrS (darunavir/cobicistat with rilpivirine and/or dolutegravir) was associated with higher decreases in Cr-eGFR [adjusted median difference (±SD) -3.5 ± 1.6 (95% CI -6.6 to -0.3), P = 0.047], and a decrease up to or higher than 15 mL/min/1.73 m2 was more frequent [adjusted OR 3.233 (95% CI 1.343-7.782), P = 0.009], with respect to darunavir/cobicistat alone. The Cr-eGFR changes between darunavir/cobicistat and darunavir/cobicistat with rilpivirine and/or dolutegravir showed more significant decreases in patients taking two or more IPTCrS at 12, 24 and 48 weeks. (ClinicalTrials.gov: NCT03042390). CONCLUSIONS: Concomitant use of darunavir/cobicistat plus IPTCrS dolutegravir, rilpivirine, or both produced an additive effect in the expected Cr-eGFR decrease.

Factors associated with readmission and mortality in adult patients with skin and soft tissue infections.

BACKGROUND: Skin and soft tissue infections (SSTIs) are a common cause of consultation, and complicated cases require hospitalization. We describe factors that are related to readmission and/or mortality of hospitalized patients diagnosed with SSTIs. METHODS: Retrospective review of hospital-admitted patients with a diagnosis of cellulitis, abscess, hidradenitis, fasciitis, and Fournier's gangrene. Cases from January 2002 to October 2015 were extracted from the diagnostic codification database of the Archives and Clinical Documentation Department. FINDINGS: We studied 1,482 episodes of hospitalized patients diagnosed with SSTIs. There were 187 (12.3%) readmissions, the most frequent diagnosis was cellulitis (72.7%), and the most commonly isolated microorganism was Staphylococcus aureus (25; 30.1%). Factors associated with readmissions were healthcare-related infections (P = 0.002), prior antibiotic therapy (P < 0.001), ischemic heart disease (P = 0.01), chronic liver disease (P = 0.001), and diabetes mellitus (DM) (P = 0.006). The number of patients who died as a result of an infection was 34 (2.2%) and, in these patients, the most common diagnosis was also cellulitis (79.4%), which in 52.9% (P = 0.001) was community acquired. DM (P = 0.01), heart failure (P = 0.001), and chronic liver disease (P = 0.003) were the most frequent comorbidities. This group presented more complications (P < 0.005) such as endocarditis (P < 0.005), amputation (P = 0.018), severe sepsis (P < 0.005), and septic shock (P < 0.001). CONCLUSIONS: Readmitted patients had healthcare-related S. aureus infection, had received prior antibiotic therapy, and presented comorbid conditions such as ischemic heart disease, peripheral vascular disease, chronic liver disease, or DM. Comorbidities such as advanced age, DM, heart failure, and chronic liver disease were associated with complications and higher infection-related mortality.

Fiebre Q aguda sintomática: 87 casos en un área de Mallorca / Symptomatic acute Q fever: A series of 87 cases in an area of Mallorca

INTRODUCCIÓN: La fiebre Q (FQ) es una zoonosis de distribución mundial causada por Coxiella burnetii ( C . burnetii). La infección aguda puede cursar asintomática o producir síndrome febril, hepatitis o neumonía y la infección crónica se suele presentar como endocarditis. Los datos sobre FQ en las islas Baleares son escasos. Métodos Se presenta una serie de casos con información retrospectiva desde marzo de 2003 a diciembre de 2011 de los casos con serología y cuadro clínico compatible con FQ aguda en el Hospital Son Llàtzer de Palma de Mallorca. Se consideró FQ aguda cuando, en un paciente con sospecha clínica, el título de IgM en fase II fue positivo (≥ 1/40), con IgG positiva (≥ 1/80) o cuando existió en fase de convalecencia seroconversión del título de IgG a C. burnetii. Se diagnosticaron 87 casos de FQ aguda. La mediana de edad fue de 50 años (rango intercuartílico: 21-89) y 69 (79,3%) eran hombres. La fiebre y la cefalea fueron los síntomas más frecuentes. El diagnóstico fue de: neumonía en 39 (44,8%) pacientes, síndrome febril aislado en 21 (24,1%), hepatitis aguda en 19 (21,8%) y el resto otras entidades. En 52 casos (59,8%) existió alguna elevación de enzimas hepáticas. El tratamiento con doxiciclina (solo o en combinación) fue prescrito en 29 (33,4%). El seguimiento se realizó en 57 (65,5%) de los pacientes. La evolución fue favorable en la mayoría, solamente un paciente con FQ aguda presentó durante el seguimiento títulos compatibles con FQ crónica. CONCLUSIÓN: La FQ aguda sintomática es frecuente en nuestro medio. La afectación pulmonar fue predominante. Solo un tercio de los pacientes fueron tratados con doxiciclina. No hubo ningún seguimiento tras la primera determinación serológica en 30 pacientes (34,5%). No se evidenciaron complicaciones significativas en el curso de la infección

INTRODUCTION: Q fever is a widespread zoonotic infection caused by Coxiella burnetii (C. burnetii). Acuteinfection varies from a self-limited flu-like illness to pneumonia or hepatitis. METHODS: A retrospective case study from March 2003 to December 2011 was conducted in the Hospital Son Llàtzer in Palma de Mallorca. Acute Q-fever was diagnosed in a patient with clinical suspicion and IgMin phase II positive (≥ 1/40), with a positive IgG (≥1/80), or when IgG seroconversion was observed during convalescence. A total of 87 cases of acute Q fever were diagnosed. The median age was 50 years (range21-89), and 69 (79.3%) were male. Fever and headache were the most common symptoms. Pneumonia was diagnosed in 39 (44.8%) patients, febrile episode in 21 (24.1%), and acute hepatitis in 23 (25.6%).Increased serum transaminases were observed in 19 (21.8%). Doxycycline was prescribed in 29 cases(33.4%). There were 30 (34.5%) patients lost to follow up after hospital discharge. A favorable outcome was observed in all other cases. Only one new case progressed to chronic Q fever. RESULTS: A total of 87 cases of acute Q fever were diagnosed. The median age was 50 years (range 21-89), and 69 (79.3%) were male. Fever and headache were the most common symptoms. Pneumonia was diagnosed in 39 (44.8%) patients, febrile episode in 21 (24.1%), and acute hepatitis in 23 (25.6%).

Pneumonia was the most common clinical presentation. Even although doxycycline was prescribed in a small number of patients, a favorable outcome was observed in all cases

Infecciones de piel y partes blandas en pacientes hospitalizados: factores epidemiológicos, microbiológicos, clínicos y pronósticos / Skin and soft-tissue infections in hospitalized patients: Epidemiology, microbiological, clinical and prognostic factors

INTRODUCCIÓN: Las infecciones de piel y partes blandas (IPPB) son un motivo de consulta bastante frecuente en los servicios hospitalarios, y los casos que se complican requieren hospitalización. Sin embargo, hay escasos estudios en nuestro ámbito en los que se describan estas infecciones. Material y métodos Estudio observacional retrospectivo de los episodios con diagnóstico de foliculitis, celulitis, erisipela, abscesos, hidrosadenitis, forúnculo, impétigo, fascitis, mionecrosis y gangrena de Fournier extraídos de la base de datos de codificación diagnóstica del Servicio de Archivos y Documentación Clínica del Hospital Son Llàtzer desde enero de 2002 a noviembre de 2011.ResultadosSe estudiaron 996 episodios en 841 pacientes hospitalizados con algún diagnóstico de IPPB. La entidad diagnosticada con mayor frecuencia fue la celulitis/erisipela (66,7%); el origen de la IPPB era comunitario (77%) y la mayoría de pacientes presentaban comorbilidades, sobre todo diabetes (33%) e insuficiencia cardiaca (17,7%). El microrganismo aislado más frecuentemente fue S.aureus (35,1%), presentaban resistencia a la meticilina (SARM) 19 casos (12,9%), siendo la mayoría de los casos resistentes a SARM (84,2%) de origen nosocomial o asociado a cuidados. El tratamiento empírico se realizó con más frecuencia en monoterapia con aminopenicilinas con inhibidores de betalactamasas (35,5%). Los nuevos fármacos para grampositivos (linezolid, daptomicina y tigeciclina) se utilizaron más frecuentemente en pacientes con comorbilidades que presentaron más complicaciones (p < 0,001) y mayor riesgo de mortalidad (p = 0,001). Durante el ingreso fallecieron el 10,9% de los pacientes, pero solamente en el 2,7% la mortalidad se relacionó con la IPPB. CONCLUSIONES: Las IPPB que se atienden con más frecuencia en pacientes hospitalizados son sobre todo celulitis/erisipela, la mayoría de ellas adquiridas en la comunidad. La infección por SARM se relaciona principalmente con la asistencia sanitaria. El uso de los nuevos antibióticos frente a grampositivos fue bastante limitado

INTRODUCTION: Skin and soft-tissue infections (SSTIs) are a frequent cause of consultation in emergence services, and complicated cases require hospitalization. However there are few data in our setting about the clinical characteristics of these infections. MATERIAL AND METHODS: A retrospective review of hospital admitted patients with a diagnosis of folliculitis, cellulitis, erysipelas, abscesses, hidradenitis, furuncle, impetigo, fasciitis and Fournier's gangrene. Cases were extracted from the data base of diagnostic codes of the Archive and Clinical Documentation Department of Son Llàtzer Hospital from January 2002 to November 2011.RESULTS: We studied 996 episodes in 841 hospitalized patients with any diagnosis of SSTIs. Cellulitis/erysipelas (66.7%) was the most frequently diagnosed condition, with 77% of all SSTIs being community acquired, and the majority of patients had comorbidities, mainly diabetes (33%) and heart failure(17.7%). The most frequent isolated microorganism was S.aureus (35.1%), in 19 (12.9%) cases with methicillin-resistance (MRSA), 84.2% of them were nosocomial or health care acquired. Monotherapywith aminopenicillin with clavulanic acid was the empiric treatment most frequently used (35.5%). Newantibiotics for Gram-positive cocci (linezolid, daptomycin, and tigecycline) were used in patients with comorbidities that presented more complications (P < .001) and more risk of mortality (P = .001). During admission 10.9% of patients died, but only in 2.7% of them mortality was related to the SSTIs. CONCLUSIONS: SSTIs attended most frequently in hospitalized patients are mainly cellulitis/erysipela, the majority community acquired. MRSA infections are mainly health care related. Use of new antibiotic for Gram-positive cocci was limited

Experiencia de una unidad monográfica de tuberculosis: primeros 500 casos / Experience of a Monographic Tuberculosis Unit: The First 500 Cases

Introducción: La tuberculosis (TB) continúa siendo una enfermedad muy prevalente aunque desde el año 2002 el número de casos anuales muestra una tendencia decreciente en el mundo y también en nuestro país, donde la incidencia es muy variable entre comunidades autónomas. El objetivo principal de este estudio es describir la experiencia de una unidad monográfica de TB de un centro hospitalario de segundo nivel. Pacientes y métodos: Estudio descriptivo de los casos de TB diagnosticados en una unidad monográfica de un hospital secundario entre 2003 y 2011. Se recogieron datos demográficos, clínicos, epidemiológicos y microbiológicos para su análisis. Resultados: Se analizaron 500 casos de TB, encontrando una incidencia anual creciente en todos los subgrupos, incluyendo población autóctona e inmigrante. La mayoría (63,8%) eran varones, con una mediana de edad de 36 años (rango 8 meses-90 años). Un 39,8% de los pacientes era inmigrante. En un 11% de los casos existía coinfección con el virus de la inmunodeficiencia humana. La localización fue pulmonar en el 63,8% de los casos. La letalidad global fue del 5,8% sin encontrar diferencias significativas entre subgrupos (incluyendo población inmigrante y personas infectadas por el virus de la inmunodeficiencia humana). Conclusiones: A pesar de la tendencia descendente global en cuanto al número de casos de TB declarados, en nuestra serie esta es creciente en todos los subgrupos. La existencia de una unidad monográfica de TB junto con un exhaustivo programa de estudio de contactos podría explicar este hallazgo (AU)

Introduction: Tuberculosis (TB) remains a highly prevalent and potentially severe disease. However, since 2002 the annual incidence has been decreasing both worldwide and in Spain, where the incidence varies widely between regions. The main objective of this study is to describe the experience of a monographic TB unit in a second level hospital. Patients and methods: A descriptive study was carried out which included all cases of TB diagnosed in a monographic unit of a secondary hospital between 2003 and 2011. Demographic, clinical, epidemiological and microbiological data were recorded. Results: We analyzed 500 TB cases and found an increasing annual incidence in all subgroups, including native and immigrant populations. Most cases (63.8%) were male, with a median age of 36 years (range 8 months–90 years). In total, 39.8% of patients were foreign born. Coinfection with human immunodeficiency virus (HIV) was found in 11.0% of cases. The pulmonary form was most frequently diagnosed (63.8%). Overall mortality was 5.8% with no significant differences between groups (including foreign born and HIV positive patients). Conclusions: Although TB incidence is globally decreasing, in our study we found an increasing number of cases in recent years in all subgroups, which can be explained by this being a monographic unit with an intensive contact tracing program (AU)
