RESUMEN

BACKGROUND: Burnout can significantly impact practitioners and their co-workers, and hence patients. There are no data for the prevalence of burnout in French ENT specialists, or for associated risk factors. MATERIAL AND METHODS: A French national cross-sectional online survey was performed on the initiative of the ENT National Professional Council (CNPORL), contacting all ENT specialists whose e-mail address was known to the French Society of ENT, the National Professional Council or the National ENT Union. The 22-question Maslach Burnout Inventory (MBI) was sent out, along with 16 extra questions on possible risk factors. OBJECTIVES: The study sought to assess the prevalence and severity of burnout, using the MBI, and to analyze risk factors. RESULTS: Among the 1936 physicians, 406 contacted responded to the questionnaire (21%). Mean age was 47±14 years (range, 25-77 years); 53% male, 47% female. 196 (48%) reported burnout, including 20 (5%) severe burnout. Independent risk factors for burnout of whatever severity, comprised social interaction issues, history of identified burnout, and medicolegal pressures. Social interaction issues were independently associated with specifically severe burnout. CONCLUSIONS: Burnout affected almost half of respondents. There are identifiable risk factors, for which improvements could be implemented.

RESUMEN

OBJECTIVE: In some patients the immune response triggered by SARS-CoV-2 is unbalanced, presenting an acute respiratory distress syndrome which in many cases requires intensive care unit (ICU) admission. The limitation of ICU beds has been one of the major burdens in the management around the world; therefore, clinical strategies to avoid ICU admission are needed. We aimed to describe the influence of tocilizumab on the need of transfer to ICU or death in non-critically ill patients. METHODS: A retrospective study of 171 patients with SARS-CoV-2 infection that did not qualify as requiring transfer to ICU during the first 24h after admission to a conventional ward, were included. The criteria to receive tocilizumab was radiological impairment, oxygen demand or an increasing of inflammatory parameters, however, the ultimate decision was left to the attending physician judgement. The primary outcome was the need of ICU admission or death whichever came first. RESULTS: A total of 77 patients received tocilizumab and 94 did not. The tocilizumab group had less ICU admissions (10.3% vs. 27.6%, P=0.005) and need of invasive ventilation (0 vs 13.8%, P=0.001). In the multivariable analysis, tocilizumab remained as a protective variable (OR: 0.03, CI 95%: 0.007-0.1, P=0.0001) of ICU admission or death. CONCLUSIONS: Tocilizumab in early stages of the inflammatory flare could reduce an important number of ICU admissions and mechanical ventilation. The mortality rate of 10.3% among patients receiving tocilizumab appears to be lower than other reports. This is a non-randomized study and the results should be interpreted with caution.

RESUMEN

Cardiovascular diseases have become a significant cause of morbidity in patients with human immunodeficiency virus (HIV) infection. Heart transplantation (HT) is a well-established treatment of end-stage heart failure (ESHF) and is performed in selected HIV-infected patients in developed countries. Few data are available on the prognosis of HIV-infected patients undergoing HT in the era of combined antiretroviral therapy (cART) because current evidence is limited to small retrospective cohorts, case series, and case reports. Many HT centers consider HIV infection to be a contraindication for HT; however, in the era of cART, HT recipients with HIV infection seem to achieve satisfactory outcomes without developing HIV-related events. Consequently, selected HIV-infected patients with ESHF who are taking effective cART should be considered candidates for HT. The present review provides epidemiological data on ESHF in HIV-infected patients from all published experience on HT in HIV-infected patients since the beginning of the epidemic. The practical management of these patients is discussed, with emphasis on the challenging issues that must be addressed in the pretransplant (including HIV criteria) and posttransplant periods. Finally, proposals are made for future management and research priorities.

RESUMEN

OBJECTIVES: The aim of the study was to identify antiretroviral-related errors in the prescribing of medication to HIV-infected inpatients and to ascertain the degree of acceptance of the pharmacist's interventions. METHODS: An observational, prospective, 1-year study was conducted in a 750-bed tertiary-care teaching hospital by a pharmacist trained in HIV pharmacotherapy. Interactions with antiretrovirals were checked for contraindicated combinations. Inpatient antiretroviral prescriptions were compared with outpatient dispensing records for reconciliation. Renal and hepatic function was monitored to determine the need for dose adjustments. RESULTS: The prescriptions for 247 admissions (189 patients) were reviewed. Sixty antiretroviral-related problems were identified in 41 patients (21.7%). The most common problem was contraindicated combinations (n=20; 33.3%), followed by incorrect dose (n=10; 16.7%), dose omission (n=9; 15%), lack of dosage reduction in patients with renal or hepatic impairment (n=6; 10% and n=1; 1.7%, respectively), omission of an antiretroviral (n=6; 10%), addition of an alternative antiretroviral (n=5; 8.3%) and incorrect schedule according to outpatient treatment (n=3; 5%). Fifteen out of 20 errors were made during admission. A multivariate analysis showed that factors associated with an increased risk of antiretroviral-related problems included renal impairment [odds ratio (OR) 3.95; 95% confidence interval (CI) 1.39-11.23], treatment with atazanavir (OR 3.53; 95% CI 1.61-7.76) and admission to a unit other than an infectious diseases unit (OR 2.50; 95% CI 1.28-4.88). Use of a nonnucleoside reverse transcriptase inhibitor was a protective factor (OR 0.33; 95% CI 0.13-0.81). Ninety-two per cent of the pharmacist's interventions were accepted. CONCLUSION: Antiretroviral-related errors affected more than one-in-five patients. The most common causes of error were contraindicated or not recommended drug-drug combinations and dose-related errors. A clinical pharmacist trained in HIV pharmacotherapy could help to detect errors and reduce the duration of their effect.

RESUMEN

Since the introduction of combined antiretroviral therapy (cART), solid organ transplantation (SOT) has become a therapeutic option for the HIV-positive population. In contrast with liver and kidney transplantation, only three simultaneous pancreas-kidney transplants (SPKT) have been reported among HIV-infected patients. Herein we have reported the first SPKT in an HIV-infected patient in Spain. The pancreas graft failed at 2 weeks and the patient died at 9 months because of a Pseudomonas aeruginosa infection. The three recipients reported in the literature lived, despite the failure of both the pancreas and kidney grafts in one subject. Despite the poor outcome of our case, HIV-1 infection was controlled after transplantation (stable CD4(+) cells and no AIDS-related events), and the kidney graft functioned with no episodes of rejection. The cART regimen used in the pretransplant period was switched at the time of transplantation to raltegravir and two nucleoside reverse transcriptase inhibitors (NRTI). Raltegravir has no interactions with immunosuppressive drugs. Target plasma levels of tacrolimus were achieved at a dose similar to that used in HIV-negative transplant recipients. The most adequate antiretroviral regimen for HIV-infected SOT recipients has not yet been established; however, one may consider switching protease inhibitors or non-NRTI-based regimens for a raltegravir-based regimen at the time of transplantation.

RESUMEN

Objetivo Conocer la duración y los motivos de cambio de las distintas combinaciones de fármacos utilizadas como inicio del tratamiento antirretroviral en pacientes naive. Métodos Estudio observacional y retrospectivo en el que se incluyeron todos los pacientes con infección por VIH que iniciaron tratamiento antirretroviral en un hospital universitario de referencia de alta tecnología durante el periodo comprendido entre el 1 de enero de 2003 y el 31 de diciembre de 2005. El seguimiento se realizó hasta el 31 de diciembre de 2008. Para estimar la probabilidad acumulada de interrupción del tratamiento se utilizó el método de Kaplan-Meier. Resultados Se incluyeron un total de 441 pacientes. La mediana de duración del primer tratamiento fue de 384 (intervalo intercuartil 84–1.290) días. Los regímenes basados en inhibidores de la transcriptasa inversa no análogos de nucleósidos y aquellos que incluían como análogos de nucleósidos abacavir o tenofovir en combinación con lamivudina o emtricitabina presentaron una duración significativamente mayor que el resto. Los principales motivos de finalización fueron las reacciones adversas aunque en un porcentaje menor que el obtenido en estudios anteriores. No se hallaron asociaciones entre el resto de características de los pacientes o del tratamiento y el riesgo de interrupción. Discusión Aunque la duración del primer tratamiento antirretroviral sigue siendo corta, actualmente se producen menos cambios por reacciones adversas y por pérdidas de seguimiento. Los motivos podrían ser una mejor tolerancia y una menor complejidad. No obstante, son necesarios más estudios para determinar el beneficio de un régimen frente a otro y poder generalizar estos resultados (AU)


Objective To determine the duration of and reasons behind changing the various combinations of drugs used for the initiation of antiretroviral treatment in naïve patients. Methods A retrospective observational study that included all patients with HIV infection who started antiretroviral therapy in a high-tech university reference hospital during the period from 1 January 2003 and 31 December 2005. Patients were followed until 31 December 2008. To estimate the cumulative probability of discontinuation the Kaplan-Meier method was used. Results A total of 441 patients were included.

The regimen based on non-nucleoside reverse transcriptase inhibitors and those that included as nucleosides abacavir or tenofovir in combination with lamivudine or emtricitabine showed a significantly longer duration than the rest. The main reasons for termination were the side effects, although in a lesser percentage than that obtained in previous studies. No associations were found between the rest of the characteristics of the patients or of the treatment and the risk of termination. Discussion Although the duration of the first antiretroviral treatment remains short, currently fewer changes are made due to side effects and due to loss to follow-up. The reasons may be better tolerance and less complexity. However, more studies are needed to determine the benefits of one regimen or another, and to be able to generalise the results (AU)

RESUMEN

The relationship between adherence, antiretroviral regimen, and viral load (VL) suppression was assessed through a 1 year prospective follow-up study among 1142 HIV-infected patient. Patients on antiretroviral therapy who attended to the pharmacy during a 6-month period were considered eligible. Those included in the final analysis were patients who had been taking the same antiretroviral therapy for > or =6 months since their inclusion. The cohort included patients taking first line therapy (n = 243) and antiretroviral-experienced patients (n = 899). Naive patients who were included had to have reached undetectable VL at enrollment. Antiretroviral-experienced patients with detectable VL determinations in the previous 6 months were excluded. Adherence was measured by means of announced pill counts and dispensation pharmacy records. Of patients, 58% were taking NNRTI, 31.4% boosted PI, and 10.6% unboosted PI-based regimens. Overall, the relative risk of virologic failure was 9.0 (95% CI 4.0-20.1) in patients with adherence 80-89.9%, 45.6 (95% CI 19.9-104.5) with adherence 70-79.9%, and 77.3 (95% CI 34.2-174.9) with adherence <70%, compared with adherence of > or =90%. The risk of virologic failure in patients with adherence <90% taking unboosted PI was 2.5 times higher than the group taking boosted PI (95% CI 1.2-5.3). There were no statistical differences in patients taking boosted PI and those who were taking NNRTI. Less than 95% of adherence is associated with high virologic success. For patients taking NNRTI- or boosted PI-based regimens with adherence rates of 80%, the failure rate is <10%. These data do not affect the goal of achieving the highest level of adherence possible.

RESUMEN

The aim of the present study was to evaluate the degree of metabolic control obtained with the use of the insulin analogue lispro compared to the previous regimen with classical regular insulin in children and adolescents with Type 1 diabetes mellitus. HbA1c, lipid metabolism, body mass index (BMI), frequency of severe hypoglycaemia, carbohydrate intake, total daily insulin requirements and its distribution during the day were analysed in 44 diabetics patients (57% males and 43% females) throughout a 3-yr period. The mean age of the patients at the beginning of the study was 15.6 +/- 2.7 yr with a mean duration of the disease of 8.01 +/- 3.4 yr. All data were evaluated for the year before the change of treatment, and 1 yr (44 patients), 2 yr (19 patients) and 3 yr (13 patients) after the change. HbA1c levels did not significantly change (6.6 +/- 1.1% with regular insulin, 6.32 +/- 1.05% in the 1st year with lispro, 6.6 +/- 1.1% in the 2nd yr with lispro, 6.33 +/- 0.9% in the 3rd yr with lispro). However, significant differences (p = 0.03) were found after 3 yr of treatment in those patients who changed to insulin lispro therapy due to a bad glycaemic control. The total daily insulin dose (U/kg/d) remained unchanged. The total short-acting/intermediate-acting insulin ratio significantly decreased (45.9 +/- 0.1% regular insulin; 37.2 +/- 0.1% 1st yr lispro (p < 0.001); 33.6 +/- 0.1% 2nd yr lispro (p < 0.05); 35.5 +/- 0.1% 3rd yr lispro (p < 0.05). BMI and lipid profile remained unchanged. The self-reported daily carbohydrate in take significantly decreased due to a reduction of snacks. Total number of episodes of severe hypoglycaemia did not change significantly. In conclusion insulin lispro treatment did not modify the daily insulin dose, but reduced the short-acting/intermediate acting insulin ratio. The metabolic control remained unchanged. The number of patients reporting severe hypoglycaemia was similar despite the treatment schedule. After this 3-yr duration trial all patients decided to continue the treatment with lispro insulin.

RESUMEN

Patients with multiple myeloma (MM) refractory to chemotherapy can only benefit from supportive measures and have a very short survival. Thalidomide has recently shown antitumor activity in patients with refractory myeloma. Twenty-three patients (12 men and 11 women; median age, 72 years) with advanced MM were treated with thalidomide. Sixteen patients had refractory disease and seven had untested relapse. The median dose of thalidomide was 400 mg d (range, 200 to 800 mg/d). The drug was generally administered in two divided doses. Five patients required treatment discontinuation because of toxicity. Twelve of 23 patients (52%) responded. Three (13%) achieved a partial response, with greater than 50% reduction in serum monoclonal (M)-protein levels, and nine (39%) attained a minimal response, with a greater than 25% decrease in serum M-protein levels. No decrease in the size of soft tissue plasmacytomas was observed in six patients with extramedullary involvement.

RESUMEN

Thalidomide is active in patients with refractory myeloma. Seventeen patients (nine men/eight women, median age 73 years) with multiple myeloma (MM) were treated with thalidomide. Fifteen patients had refractory disease and two untested relapse. The median dose of thalidomide was 500 mg (range, 200-800 mg). Nine of the 17 patients (53%) responded. The response rate was significantly higher in patients with no extramedullary disease than in those with soft tissue masses (75% CI: 43-95% versus 0%; P = 0.01)). Of note, no decrease in the size of soft tissue plasmacytomas was observed in all the five patients who had extramedullary involvement. This data suggests that the mechanism of action and effectiveness of thalidomide might depend on the site of the tumour cells.

RESUMEN

La adhesión al tratamiento antirretroviral constituye unos de los factores clave para conseguir el éxito de la terapia antirretroviral, y en consecuencia evitar en lo posible el fracaso terapéutico y la aparición de resistencias, optimizando la utilización de recursos sanitarios. Las causas que pueden influir sobre la adhesión de los pacientes dependen del individuo, su relación con la enfermedad, el régimen terapéutico y la relación con el equipo de atención asistencial. La tasa de adhesión se calcula aplicando alguno de los métodos directos (determinación de valores plasmáticos) o indirectos (entrevista, cuestionario, recuento medicación sobrante, evolución de la carga viral); al no ser ninguno de ellos un método exacto ni fiable, es necesario combinarlos. En los centros de atención a pacientes infectados por el VIH es necesario planificar y establecer una estrategia de mejora de la adhesión al tratamiento antirretroviral, implicando a representantes de cada uno de los estamentos que participan en la atención (médico, enfermera, farmacéutico, psicólogo o psiquiatra), así como aprovechar los grupos de soporte, asociaciones de enfermos, ONG, etc. La importancia del tema requiere tomar las acciones necesarias para garantizar una tasa mínima de adhesión al tratamiento (AU)

RESUMEN

Los fármacos antirretrovirales actúan en dos fases fundamentales del ciclo replicativo del VIH. Unos fármacos inhiben la transcriptasa inversa (TI), evitando la síntesis de la cadena de ADN proviral, y otros inhiben la proteasa, evitando la formación de las proteínas estructurales del VIH, necesarias para la formación de partículas virales maduras. En función de estos fármacos, el tratamiento de la infección por el VIH se basa en la actualidad en la combinación de 3 o más fármacos antirretrovirales que inhiben la TI (tratamiento convergente) o la TI y la proteasa del VIH (tratamiento divergente). En el siguiente capítulo se describen las indicaciones de tratamiento antirretroviral y las combinaciones de fármacos antirretrovirales utilizadas. En este capítulo se describe la estructura química, el mecanismo de acción, la actividad in vitro, las características farmacocinéticas, las interacciones medicamentosas, los efectos secundarios, la posología, el nombre y las presentaciones comerciales de los fármacos antirretrovirales que se pueden utilizar en la actualidad (AU)

RESUMEN

BACKGROUND: Strategies for treatment of HIV need to be considered in terms of combining potency, safety, and convenience of dosage. However, regimens including once-daily protease inhibitors are not yet available. We have performed a pilot study to determine an indinavir/ritonavir (IND/RTV) regimen for once-daily dosing, by monitoring plasma levels. METHODS: Antiretroviral-naive HIV-infected adults were eligible. Therapy was zidovudine/lamivudine 1 pill twice daily plus IND/RIT (liquid formulation) 800/100 mg twice daily with food. At 4-week intervals, plasma levels were measured and dosage of IND/RIT switched to 1000/100 mg daily and then 800/200 mg daily. If 12-hour minimum concentrations (Cmin12h) of IND were too low (<0.1 microg/ml) with IND/RIT 1000/100 mg once daily in the first half of the patients, it was planned to switch directly to 800/200 mg once daily in the other half. RESULTS: In all, 27 patients were recruited. Mean baseline CD4+ lymphocyte count was 107 x 106/L (range, 4-623 x 106/L). Eleven patients (40%) discontinued the study medication within the first 4 weeks due to clinical progression (n = 3) or grade 1-2 RTV related side effects (n = 8). Nine patients (group A) switched from 800/100 mg twice daily to 1000/100 mg once daily and then to 800/200 mg once daily. Seven patients (group B) switched directly to 800/200 mg once daily. At week 32, viral load was <5 copies/ml in 15 of 16 patients (94%). RTV levels were always <2.1 microg/ml. The mean and 95% confidence interval for IND Cmin and Cmax in microg/ml was: using IND/RTV 800/100 mg twice daily (n = 16) 1.4 (0.5-2.3) and 6.7 (4.4-9.1), respectively; using IND/RTV 1000/100 mg once daily (n = 9) 0.18 (0-0.41) and 8.6 (3.3-14), respectively; and using 800/200 mg once daily (n = 16) 0.38 (0-0.9), and 7.5 (0.8-14.8). For all 16 patients who received IND/RTV 800/100 mg twice daily, the Cmin value for IND was >/=0.1 microg/ml. Conversely, IND Cmin was <0.1 microg/ml in 4 of 9 receiving 1000/100 mg once daily but in only 1 of 16 receiving 800/200 mg once daily. CONCLUSION: Once-daily regimen of IND/RIT is feasible and deserves further evaluation in larger randomized trials. Liquid formulation of RIT was not well tolerated by our antiretroviral-naive patients despite lower than suggested doses.

RESUMEN

BACKGROUND: To assess the economical impact of vancomycin use versus teicoplanin use as antibiotic prophylaxis for patients undergoing cardiac surgery for valve replacement (VR) and coronary artery by-pass (CABS) procedures. PATIENTS AND METHODS: This is an ancillary cost minimization analysis of a double blinded, parallel groups, randomised clinical trial (RCT), with the main objective of comparing the safety and efficacy of these antibiotics. 500 patients were included in the study; 267 in the CABS group and 233 in the VR group. The CABS patients received 1 g vancomicin or 400 mg teicoplanin, plus 150 mg netilmicin. The VR group received a second dose of each drug after extracorporeal circulation. In order to calculate the costs we considered the direct cost of the drug, the i.v. mix and the administration costs, together with personnel and structure costs. We considered two different situations: the administration of drugs within the surgical room theatre and in the medical ward. RESULTS: The demographic data of both groups were comparable. The frequency of severe adverse drug reactions (ADR) were similar (0.4%) in both groups, as well as the post-operative infection rates (8.6%). Differences were seen in the frequencies of low severity ADRs: 20.4% in the vancomycin group and 1.6% in the teicoplanin group. When the antibiotics were administered in the surgical room, among CABS patients the costs were 8,265 pts. for the teicoplanin group and 12,005 pts. for the vancomycin group; while among VR patients, costs were respectively 11,661 pts. and 14,528 pts. Administration costs of teicoplanin and vancomycin within a medical ward setting, however, the costs were 6,740 pts. and 2,809 pts. for CABS patients, and 5,308 pts. and 10,140 pts. for VR patients, respectively. CONCLUSIONS: The costs of antibiotic prophylaxis among cardiac surgery patients heavily depends on the setting and circumstances of drug administration. The minimization cost analysis indicates that teicoplanin is the most cost-effective option if the drug is administered within the surgical area, while vancomycin is the less costly option when administered within the medical ward. However, if the second option is to be chosen, it is necessary to assure the right plasmatic drug levels of the antibiotic at the beginning of the surgical procedure.
