Resistant hypertension: Diagnosis, evaluation, and treatment practical approach.

The term RH describes a subgroup of hypertensive patients whose BP is uncontrolled despite the use of at least three antihypertensive drugs in an appropriate combination at optimal or best tolerated doses. True RH is considered when appropriate lifestyle measures and treatment with optimal or best tolerated doses of three or more drugs (a thiazide/thiazide-like diuretic, plus renin-angiotensin system -RAS- blocker and a calcium channel blocker -CCB-) fail to lower office BP to <140/90 mmHg; besides the inadequate BP control should be confirmed by home blood pressure monitoring (HBPM) or 24-hour ambulatory; and evidence of adherence to therapy and exclusion of secondary causes of hypertension are required. RH patients are at a high risk of cardiovascular events and death. RH is associated with a higher prevalence of end-organ damage. When stricter criteria are applied, a reasonable estimate of the prevalence of true RH is 5 % of the total hypertensive population. The predominant hemodynamic pattern appears to be increased systemic vascular resistance and plasma volume with normal or even low cardiac output. We must rule out pseudo-resistance before diagnosing true drug resistance. RH is a therapeutic challenge, and its management includes lifestyle interventions, avoiding nonadherence to treatment, avoiding inertia, appropriate use of antihypertensive drugs based on current evidence, especially long-acting diuretics, and the addition of mineralocorticoid receptor antagonists. RCTs to identify the most protective medical therapy in RH are needed. A series of drugs in different stages of investigation could significantly impact RH treatment in the future.

[Perception and identification of barriers to the use of digital technologies in arterial hypertension]. / Percepción e identificación de barreras para la utilización de tecnologías digitales en hipertensión arterial.

INTRODUCTION: Electronic devices and communication technologies are increasingly used to provide medical care to patients with high blood pressure. The main objective was to evaluate doctors' perception on the usefulness of digital technologies in hypertension. The secondary objectives were to evaluate the prevalence of use of digital technologies in the follow-up of patients with hypertension and to identify the barriers perceived by doctors for their implementation in the Argentine Republic. METHODS: Observational, cross-sectional, multicenter study, based on a self-administered questionnaire, in the Argentine Republic, and coordinated by the Epidemiology group of the Argentine Society of Arterial Hypertension. POPULATION: Doctors who care for patients with high blood pressure. RESULTS: 247 responses were obtained, 35.6% were women and 64.4% men; 92.3% indicated that the use of digital technologies was useful to improve therapeutic adherence; 54.7% received blood pressure results at home through some digital means; 41.3% regularly carry out teleconsultations, only 6.1% through specific digital health platforms, 29.1% through non-specific platforms, by telephone 21.9% and by email (asynchronous) 10.9%. The main perceived barriers were: availability, financial remuneration, regulations, connectivity problems and lack of time. CONCLUSION: The perception of professionals is favorable, as they considered these technologies useful to improve therapeutic adherence, which could have a facilitating effect on their implementation, although the perceived barriers are part of organizational issues to be resolved.

Introducción: Los dispositivos electrónicos y tecnologías de la comunicación se emplean cada vez más frecuentemente para brindar atención médica a los pacientes con hipertensión arterial. El objetivo principal del trabajo fue evaluar la percepción de los médicos sobre la utilidad de las tecnologías digitales en hipertensión arterial. Los objetivos secundarios fueron evaluar la prevalencia de uso de tecnologías digitales en el seguimiento de pacientes con hipertensión arterial e identificar las barreras percibidas por los médicos para la implementación de las mismas en la República Argentina. Métodos: Estudio observacional, de corte transversal, multicéntrico, basado en un cuestionario autoadministrado, en el ámbito de la República Argentina y coordinado por el grupo de Epidemiología de la Sociedad Argentina de Hipertensión Arterial. Población: Médicos que realizan atención de pacientes con hipertensión arterial. Resultados: Se obtuvieron 247 respuestas, 35.6% fueron mujeres y 64.4% hombres; el 92.3 % consideró de utilidad el uso de tecnologías digitales para mejorar la adherencia terapéutica. Reciben resultados de presión arterial en domicilio por algún medio digital 54.7%. Realizan habitualmente teleconsultas 41.3%, solamente el 6.1% por plataformas digitales específicas de salud, el 29.1% por plataformas no específicas, telefónicamente 21.9% y correo electrónico (asincrónicas) 10.9%. Las principales barreras percibidas fueron: disponibilidad, remuneración económica, reglamentación, problemas de conectividad y falta de tiempo. Conclusión: La percepción de los profesionales es favorable, considerándolas útiles para mejorar la adherencia terapéutica, por lo que podría tener un efecto facilitador en la implementación de las mismas, aunque las barreras percibidas forman parte de cuestiones organizacionales a resolver.

Position statement on use of pharmacological combinations in a single pill for treatment of hypertension by Argentine Federation of Cardiology (FAC) and Argentine Society of Hypertension (SAHA).

The present document provides scientific evidence reviewed and analysed by a group of specialist clinicians in hypertension that aims to give an insight into a pharmacological strategy to improve blood pressure control. Evidence shows that most hypertensive patients will need at least two drugs to achieve blood pressure goals. There is ample evidence showing that treatment adherence is inversely related to the number of drugs taken. Observational studies show that use of drug combinations to initiate treatment reduces the time to reach the treatment goal and reduces CVD, especially with single pill combinations (SPCs). This work, based on recommendations of the Argentine Federation of Cardiology and Argentine Society of Hypertension as a reference, aims to review the more recent evidence on SPC, and to serve as guidelines for health professionals in their clinical practice and to the wider use of SPCs for the treatment of hypertension. Evidence from clinical trials on the effectiveness and adverse effects of using SPCs are provided. An analysis is also made of the main contributions of SPCs in special populations, e.g., elderly and diabetic patients, and its use in high risk and resistant hypertension. The effects of SPCs on hypertensive-mediated organ damage is also examined. Finally, we provide some aspects to consider when choosing treatments in the economic context of Latin-America for promoting the most efficient use of resources in a scarce environment and to provide quality information to decision makers to formulate safe, cost-effective, and patient-centered health policies. Finally, future perspectives and limitations in clinical practice are also discussed.

[Position of the international forum of internal medicine on habits, lifestyle changes and a healthy environment for the prevention of cardiovascular diseases]. / Posicionamiento del foro Internacional de Medicina Interna sobre Hábitos, modificaciones del Estilo de Vida y Ambiente Saludable para la Prevención de Enfermedades Cardiovasculares.

Cardiovascular diseases (CVD), mainly ischemic heart disease and stroke, is the main cause of death worldwide and each year more people die from CVD than from any other cause. These data call for a paradigm shift, where health promotion and cardiovascular prevention will acquire a central role in health policies. From this perspective, dedicating time during the consultation to promoting the acquisition of heart-healthy habits would be indicated in all individuals, regardless of cardiovascular risk classification, the role of the internist being fundamental. This position document from the International Forum of Internal Medicine (FIMI) presents the main indications regarding changes in lifestyle and acquisition of healthy habits to prevent CVD. The different sections will address topics including: nutrition, physical activity, sedentary lifestyle, obesity, smoking, alcohol consumption, sleep, stress, environmental problems related to CVD and specific conditions in women. A section is included about starting CVD promotion and prevention measures at an early age, childhood and adolescence, also mentioning epigenetic aspects related to CVD. Social determinants in CVD are also taken into account, since some of these aspects, such as low socioeconomic level, modify cardiovascular risk and should be taken into account.

Las enfermedades cardiovasculares (ECV), principalmente la cardiopatía isquémica y el accidente cerebrovascular (ACV), constituyen la principal causa de muerte a nivel mundial y cada año mueren más personas por ECV que por cualquier otra causa. Estos datos requieren la necesidad de un cambio de paradigma, en donde la promoción de la salud y la prevención cardiovascular adquieran un papel central en las políticas sanitarias. Desde esta perspectiva, dedicar tiempo durante la consulta en promocionar la adquisición de hábitos cardiosaludables estaría indicado en todos los individuos, independientemente de la clasificación de riesgo cardiovascular, siendo fundamental el rol del médico internista en su función de médico de cabecera. En este documento de posicionamiento del Foro Internacional de Medicina Interna (FIMI) se presentan algunas pautas para recomendar e indicar modificaciones en el estilo de vida y adquisición de hábitos saludables para prevenir la ECV, que tienen el objetivo de ser una herramienta practica para el médico internista. Las diferentes secciones abordaran temas que incluyen: nutrición, actividad física, sedentarismo, obesidad, hábito tabáquico, consumo de alcohol, sueño, estrés, problemas ambientales relacionados a la ECV y condiciones específicas en la mujer. Se incluyó un apartado acerca de comenzar las medidas de promoción y prevención de ECV en edades tempranas, infancia y adolescencia, mencionando además aspectos epigenéticos relacionados a la ECV. Se tienen en cuenta además los determinantes sociales en ECV, ya que algunos de estos aspectos, como el bajo nivel socioeconómico, modifican el riesgo cardiovascular y debieran ser tenidos en cuenta.

Reversibility of brain lesions in a case of Neuro-Behçet's disease studied by MR diffusion.

Behçet's disease is a multisystem disorder first described in 1937 as a triad of oral and genital ulcerations and uveitis. The etiology is unknown. Involvement of the central nervous system (CNS) occurs in 10-25% of patients. Neuro-Behçet's disease (NBD) can be classified as: (1) parenchymal, with a predilection for brainstem, basal ganglia and thalami involvement, subcortical white matter damage, spinal cord lesions, and meningoencephalitic presentations; (2) vascular, which usually affects major intracranial vessels with frequent involvement of the venous sinuses, cerebral veins and rarely intracranial arteries. Even if not constantly demonstrated in the CNS a vasculitic process involving small blood vessels, including venules, is regarded as an important pathological feature. We describe the case of a patient with NBD studied with conventional and diffusion weighted MR imaging.

[Nutritional status and mortality in community acquired pneumonia]. / Estado nutricional y mortalidad en neumonía de la comunidad.

Pneumonias are a major cause of morbidity and mortality and their prognosis depends on many factors including nutritional status. This study analyzed the relationship between malnutrition and the risk of death in Community Acquired Pneumonia (CAP) patients. This is a prospective observational study. The Subjective Global Assessment (SGA) was used as a screening tool to appraise the nutritional status. Ninety-eight patients with CAP requiring hospitalization were included consecutively from October 2004 to September 2006. The clinical, bacteriological and laboratory features were recorded. Patient's nutritional condition was assessed using the SGA. The monitoring was performed until discharge, death or shunt. Persistent cough or fever, the presence of pleural effusion, malignancies or long hospitalization were associated with worse prognosis. Mortality increased in proportion to the degree of malnutrition. Thirty two CAP patients (32.65%) were classified as SGA-category A; 44 (44.90%) as SGA-B, and 22 (22.45%) as SGA-C. Pneumonia resulted in death in 3/32 SGA-A (9.37%), 8/44 SGA-B (18.18%) and 10/22 SGA-C patients. SGA-C patients showed significantly higher odds ratios for death in comparison to SGA-A patients (OR = 6.085, CI95%: 1.071-34.591; p = 0.042). Considering death as the outcome variable, SGA-A class had the highest negative predictive value (0.906), while SGA-C class showed the highest positive predictive value (0.455). These results link the nutritional status to the NAC evolution prognostic. SGA provides a simple estimation of the nutritional status and it is a good predictor of the risk of death in CAP patients.

[Diffuse ganglioneuromatosis: infrequent pathology communication and review of literature]. / Ganglioneuromatosis difusa: comunicación de una patología infrecuente y revisión de la literatura.

Ganglioneuromatosis is an infrequent disease characterized by mienteric plexus and enteric nervous fiber hyperplasia, habitually manifested by constipation, pain and abdominal distension. There are two ways of presentation: mucosa or transmural. Regularly may be associated with another pathologies like multiple endocrine neoplasia type 2 and Von Recklinghausen's disease. The objective of this publication is to present an extremely infrequent pathology and make a bibliographic review of its clinical, diagnostic, prognostic and therapeutical aspects. We present a fifty-six year old male with a six month history ofabdominal pain and pseudo-obstruction syndrome. During the hospitalization he presents infectious complications, with septic shock secondary to nosocomial pneumonia and death. A Necropsy was done and ganglioneuromatosis was diagnosed. Due to the low incidence of this pathology, it is rarely included in the differential diagnosis of pseudo-obstructive syndrome in adults. The post-mortem diagnosis moved us to perform a bibliographic search to amplify our knowledge and compare this particular case with those previously communicated by other authors.

Adherence to antihypertensive drug treatment in Argentina: A multicenter study.

Adherence to antihypertensive medication is an important challenge that doctors often face in the treatment of hypertension. Good adherence is crucial to prevent cardiovascular complications. In consequence, the present study aimed at determining the prevalence of adherence to antihypertensive treatment and identifying associated clinical variables. A multicenter cross-sectional study was conducted in 12 cities of Argentina. A systematic sampling was performed in order to select patients with hypertension and under pharmacological treatment for at least 6 months. Physicians took three BP measurements, and the level of adherence was assessed using the self-administered Morisky questionnaire (MMAS-8). Participants were classified into three levels of adherence: high adherence-MMAS score of 8; medium adherence-MMAS scores of 6 to <8; and low adherence-MMAS scores of <6. A total of 1111 individuals (62 ± 12 years old, women 49.4%) were included in the present analysis; 159 (14.3%), 329 (29.6%) and 623 (56.1%) patients had low, medium, and high adherence, respectively. The prevalence of controlled hypertension increased only in high adherent patients: 42.8%, 42.2%, and 64.5% for low, medium, and high adherence groups, respectively. Similarly, systolic BP was lower only in the high adherence group. High educational level (OR 3.47, 95% CI 2.68-4.49) and diuretic treatment (OR 0.64, 95% CI 0.47-0.88) were independent predictors of high adherence. In conclusion, more than a half of treated hypertensive patients had a high level of adherence. These patients had lower BP values and higher control levels. A high educational level predicts high adherence.

A multicenter prospective study of 515 febrile neutropenia episodes in Argentina during a 5-year period.

For better management of patients with febrile neutropenia, our study investigated the epidemiologic, microbiologic, and clinical characteristics of adult inpatients with febrile neutropenia and their mortality-associated factors. To this end, we carried out a prospective, observational, multicenter study in 28 Argentinian hospitals between 2007 and 2012. We included 515 episodes of febrile neutropenia from 346 patients, median age 49 years. Neutropenia followed chemotherapy in 77% of cases, half of the cases due to hematological malignancies. Most episodes were classified as high-risk according to MASCC criteria, and 53.6% of patients were already hospitalized at the onset of febrile neutropenia. Bloodstream infections were detected in 14% episodes; whereas an infectious source of fever was identified in 80% of cases. Mortality rate achieved to 14.95%. The binary regression analysis showed that persistence of fever at day 7, or neutropenia at day 14, dehydration and tachycardia at the onset of febrile neutropenia as well as prior infections were significantly associated with mortality. In addition to expanding our current knowledge on the features of adult patients with febrile neutropenia, present findings provide useful information for better management of them in Argentina, given the appropriate representativeness of centers participating in the study.

Regression of symptoms after selective iron chelation therapy in a case of neurodegeneration with brain iron accumulation.

We report the results of iron chelating treatment with deferiprone in a 61-year-old woman with signs and symptoms of neurodegeneration with brain iron accumulation (NBIA). After 6 months of therapy the patient's gait had improved and a reduction in the incidence of choreic dyskinesias was observed. Her gait returned to normal after an additional 2 months of therapy, at which time there was a further reduction in involuntary movements and a partial resolution of the blepharospasm.

[Abdominal bleeding due to spontaneous mesenteric vein rupture]. / Hemoperitoneo secundario a la rotura espontánea de la vena mesentérica.

UNLABELLED: Hepatic cirrhosis is the leading cause of portal hypertension and is usually associated with the development ofsplacnic varices. Variceal intraabdominal rupture is a rare cause of hemoperitoneum. A case of spontaneous mesenteric vein rupture is reported. CLINICAL CASE: 43-year-old man with hepatic cirrhosis (Child-Pugh C stage) and previous bleeding of esophageal varices, admitted to hospital because of orthostatic hypotension episodes (positive tilt test) and abdominal distention. Laboratory: anemia, low platelet count and abnormal coagulation tests. CT scan showed abdominal fluid. Exploratory laparotomy was performed and 3 liters of blood were found into the abdominal cavity. The mesenteric vein had a ruptured variceal dilatation with intermitent jet bleeding. No organ abnormalities were found. Repair of the dilated vein was performed. The patient evolved well and was dismissed from hospital ten days after admittance. OBJECTIVE: To present a case in which a rare cause of intraabdominal bleeding, usually associated with high mortality rate, is follawed by a good clinical evolution.

Severe extra-articular manifestations of rheumatoid arthritis in absence of concomitant joint involvement following long-term spontaneous remission. A case report. / Manifestaciones extraarticulares graves de artritis reumatoide en ausencia de artritis activa, tras remisión espontánea sostenida. Presentación de un caso.

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease occasionally associated with severe extra-articular manifestations, mostly in cases of longstanding highly active disease. We report the case of a 56 year-old woman diagnosed with active RA at the age of 40. After 5 years of high activity, her arthritis subsides spontaneously during pregnancy despite the lack of treatment with disease-modifying anti-rheumatic drugs. She remains without articular symptoms for 7 years, and then she develops a Felty's syndrome requiring steroid treatment and splenectomy. Following steroid withdrawal she develops pericarditis with massive serohematic pericardial effusion, still in absence of articular activity, and responds to immunosuppressive therapy and colchicine. We emphasize the unusual spontaneous and sustained joint remission without specific treatment, and the development of severe extra-articular manifestations of RA in absence of concomitant articular activity, as well as the importance of controlling inflammation.

Magnetic resonance spectroscopy facilitates assessment of intramyocellular lipid changes: a preliminary short-term study following biliopancreatic diversion.

BACKGROUND: Intramyocellular content of lipid (IMCL) appears to be important in the pathogenesis of insulin resistance, and the improvement of insulin activity observed following biliopancreatic diversion (BPD) for obesity has to be related to reduction of IMCL. This study evaluates the possibility of detecting changes after BPD in IMCL by means of H1 magnetic resonance spectroscopy. METHODS: The investigation was carried out in obese patients undergoing BPD prior to and at 1 month following the operation. Insulin sensitivity was assessed according to the homeostatic model of assessment (HOMA), and IMCL was determined by the spectroscopy of the tibialis anterior muscle. RESULTS: At 1 month following BPD, an improvement in insulin action was observed in all subjects, and in nearly all cases the IMCL signal decreased. CONCLUSION: The data from this study indicate that magnetic resonance spectroscopy can detect IMCL changes following BPD and is fully suitable for longitudinal studies on muscle metabolic status.

Analysis of Adherence to Antihypertensive Drug Treatment in an Argentinean Cohort

Abstract Background Adherence to antihypertensive medication is a major challenge in the management of hypertension, and non-adherence is an important barrier to effective management of hypertension. Objectives To determine the adherence rate to hypertensive drug treatment and the factors that influence non-adherence in a cohort of the Argentinean population. Methods A multicenter cross-sectional study was conducted in eight cities of Argentina. Consecutive hypertensive patients seen in general practice offices, receiving pharmacological treatment for at least six months were included. Blood pressure measurements were performed by physicians during the patient visit. The level of adherence was assessed using the Morisky questionnaire, and patients were divided into non-adherent and adherent. Continuous variables were compared using independent t-test. Categorical variables were compared using the χ2 test. To identify the variables independently associated with non-adherence, a forward stepwise binary regression logistic model was performed, and the results expressed as odds ratio (OR) with 95% of confidence interval. All tests were two-tailed, and p-values < 0.05 were considered statistically significant. Results A total of 852 individuals (52% women, 62 ± 13 years) were included. The main reason for lack of adherence was forgetfulness of medication intake and errors in the time of intake (~ 40% in both). Individuals with more cardiovascular risk factors (smoking, diabetes, dyslipidemia and previous cardiovascular events) had lower adherence to antihypertensive treatment, and considerably younger (~ five years younger). Conclusions Adherence rate to antihypertensive drug treatment in our study group was higher than the one reported in previous studies, and the main reason for non-adherence was forgetfulness of medication intake.

Measures of late effects in conservative treatment of breast cancer with standard or hypofractionated radiotherapy.

AIMS AND BACKGROUND: To confirm the equivalence in terms of late effects between two fractionation schedules of radiotherapy in conservative treatment of breast cancer. METHODS: Fifty-eight patients treated at our institution from 1999 to 2002, with a median follow-up of 15 months (range, 7-46 months), were evaluated retrospectively. Twenty-nine patients (group A) were treated with standard fractionation: 5000 cGy/25fx/5 weeks, and 29 patients (group B) were treated with a hypofractionated schedule: 4500 cGy/15fx/5 weeks, three fractions per week. Late effects were evaluated using the LENT-SOMA scoring scale. The cosmetic results were assessed on a five-point scale. Skin elasticity was measured using a dedicated device (Cutometer SEM 575). RESULTS: There were no differences in breast volume, age at diagnosis and follow-up between groups. The LENT-SOMA toxicity observed in groups A and B, respectively, was as follows: grade 2-3 pain in five patients in each group; grade 2 breast edema in two and three patients; grade 2-3 and grade 2 fibrosis in six and eight patients; grade 2 and grade 2-3 telangiectasia in two and three patients; grade > or = 2 and 2 arm edema in two and one patients; no ulceration or atrophy were observed. Two patients in group A and one patient in group B needed treatment for breast and arm edema and arm edema, respectively. Very good, good-acceptable, and poor cosmetic results were observed in seven and two, fifteen and nineteen, and six and eight patients, respectively. Median skin elasticity loss due to treatment was -4.19% in group A and -6.29% in group B. These results are not statistically different. CONCLUSIONS: LENT-SOMA toxicities were minimal and no differences were observed between groups. Few patients in the hypofractionated group had very good cosmetic results, but it is debatable if radiotherapy was the only cause. Skin elasticity was not different between groups. Our results seem to suggest that it is possible to treat patients with both schedules, with similar late toxicity.

Síndrome pulmón-riñón: serie de 12 casos / Pulmonary renal syndrome: series of 12 cases

El síndrome pulmón-riñón es una entidad infrecuente, que comprende un gran espectro de patologías, como las vasculitis asociadas a ANCA y la enfermedad por anticuerpos antimembrana basal glomerular entre otras. Se describen en esta serie 12 casos donde las entidades más prevalentes fueron las antes mencionadas, observándose además un caso de lupus y uno de granulomatosis con poliangeítis, que se encuentran dentro de las causas menos frecuentes. La forma de presentación clínica inicial fue simultánea renal y pulmonar en 5/12 pacientes y renal en 7/12 de los mismos. El diagnóstico temprano de dichas patologías basándose en criterios clínicos, radiológicos, de laboratorio e histológicos, permite instaurar terapéuticas tempranas como la inmunosupresión y plasmaféresis, pudiendo prevenir complicaciones tales como las infecciones y la insuficiencia renal crónica terminal, siendo las primeras la principal causa de muerte (AU)

Pulmonary-renal syndrome is an infrequent condition. It includes a wide variety of conditions such as ANCA (antineutro-phil cytoplasmic autoantibody) associated with systemic vasculitis and anti-GBM (anti-glomerular basement membrane) disease among others. In this series we describe twelve cases, in which the most prevalent diseases were the above mentioned as well as one case of lupus and one of granulomatosis with polyangiitis (these being less frequent causes). The clinical presentation was both renal and pulmonary simultaneously in five of twelve patients and renal in seven of twelve patients. Early diagnosis of this condition on the basis of clinical, radiological, histological and analytic criteria allows early treatments such as immunosuppression and plasma exchange, thus avoiding complications such as infections (the main cause of death) and terminal chronic renal failure (AU)

Efectos adversos severos del Metimazol. Comunicación de dos casos y revisión de la literatura / Severe adverse effects of Methimazole. Communication of two cases and review of the literature

Los fármacos antitiroideos constituyen uno de los pilares del tratamiento del hipertiroidismo. En nuestro país solo se encuentra disponible el metimazol. Estas drogas han sido asociadas a múltiples reacciones adversas, la mayoría leves. Efectos adversos infrecuentes pero potencialmente letales como la agranulocitosis, hepatitis y el síndrome de artritis por antitiroideos, obligan a suspender el tratamiento. Comunicamos dos casos de complicaciones infrecuentes del tratamiento con metimazol.

Antithyroid drugs are one of the cornerstones in the management of hyperthyroidism. In our country, only methimazole is available. These drugs have been related to a variety of adverse reactions, most of them minor. Infrequent but potentially lethal side effects such as agranulocytosis, hepatitis and the antithyroid arthritis syndrome, demand drug cessation. We report two cases of infrequent complications of methimazole.

Utilidad de la punción lumbar en el paciente con síndrome confusional agudo y fiebre / Usefulness of the lumbar puncture in patients with acute confusional state and fever

Los estados confusionales agudos son motivo de consulta frecuente en pacientes añosos. Se evaluó la utilidad de la punción lumbar en pacientes con fiebre y síndrome confusional agudo (SCA) cuando existe un origen extrameníngeo que explique la fiebre. Criterios de inclusión: pacientes mayores de 50 años, de ambos sexos, con fiebre y SCA admitidos entre junio de 2005 y noviembre de 2006. Se excluyeron pacientes con infección por HIV o que hubieren estado internados en las últimas 72 horas. Se realizó punción lumbar (previa realización de TAC) y se analizó el líquido cefalorraquídeo (LCR). Se incluyeron 30 pacientes. 20 pacientes tuvieron una causa extrameníngea demostrada de la fiebre (66.6%). Se diagnosticaron 6 pacientes con meningitis (20%). El análisis bacteriológico directo del LCR fue positivo en 3 pacientes (10%): en 2 casos se aisló un coco gram positivo y en el restante un bacilo gram negativo. El cultivo de LCR fue positivo en dos casos (6.6%): en un caso se aisló un Streptococcus pneumoniae y en otro Escherichia coli. El hallazgo de una causa clara de fiebre no descarta la posibilidad de meningitis concomitante. Se encontró una asociación entre la presencia de hemocultivos positivos y la de meningitis, tanto en un caso de neumonía por Streptococcus neumoniae como en una infección urinaria por Escherichia coli (p=0.0022, test exacto de Fisher). Conclusión: los pacientes añosos con SCA y fiebre podrían requerir la realización de punción lumbar como parte de la evaluación inicial, independientemente de encontrarse una causa extrameníngea de la fiebre.

Acute Confusional State (ACS) is a frequent cause for seeking professional help among elderly patients. We evaluated the usefulness of lumbar puncture in patients with acute confusional state and fever, when an evident extrameningeal cause of fever is present. All patients over 50 years of age, from both sexes, with fever and ACS, who were admitted to hospital in a period between June 2005 and November 2006, were included. Patients with a history of HIV infection and patients who had been hospitalized within the previous 72 hours were excluded. Lumbar puncture was performed, and the cerebrospinal fluid (CSF) was analyzed. Thirty patients were included. Twenty of the included patients (66.6%) had a demonstrable extrameningeal fever cause. Six patients (20%) with meningitis were detected. The CSF bacteriologic smear was positive in 3 patients (10%); in two cases a gram positive coccus was identified and in one case a gram negative bacillus. The CSF culture was positive in two patients (6.6%) for Escherichia coli (o and Streptococcus pneumoniae. The finding of a clear cause for fever does not rule out the possibility of meningitis. We found an association between the positive blood cultures and the presence of meningitis, both in a case of pneumococcal pneumonia and in a case of urinary tract infection due to Escherichia coli (p=0.0022, Fisher’s Exact test). We conclude that all elderly patients with ACS and fever may require performing a lumbar puncture as part of the initial assessment, regardless of the finding of a extrameníngeal cause of fever.
