RESUMO
BACKGROUND: MS severity may be affected by genetic, patient-related, disease-related and environmental factors. Socioeconomic status, including income and healthcare access, amongst others, may also have a role in affecting diagnostic delay or therapy prescription. In Chile, two main healthcare systems exist, public-healthcare and private-healthcare, nonetheless universal care laws (e.g., access to High Efficacy Therapy-HET), including both systems, have been recently enacted for people with MS. OBJECTIVE: To assess the role of Socioeconomic Conditions (SEC), clinical variables and public health policies on the impact of disease severity of MS patients in Chile. METHODS: Multicentric, observational, cross-sectional study including patients from two reference centres (1 national reference centre from the private-health system and 1 regional reference centre from the public-health system). SEC and clinical variables included healthcare insurance (private or public), subclassification of health insurance according to monthly income, sex, age at onset, diagnostic delay, disease duration, diagnosis before HET law (as a proxy of HET delay), and current HET treatment. Progression Index (PI), EDSS ≥6.0 and Progressive MS diagnosis were used as outcome measures. Multivariable binary logistic regression was performed. RESULTS: We included 604 patients (460 private-health, 144 public-health), 67% women, 100% white/mestizo, 88% RRMS, mean age 42±12 years, mean age at onset 32±11 years, mean disease duration 10±6 years, median diagnostic delay 0 (0-34) years, 86% currently receiving any DMT, 55% currently receiving HET, median EDSS at last visit of 2.0 (0-10), and median PI 0.17 (0-4.5). Lower monthly income was associated with higher EDSS and higher PI. In the multivariable analysis, public-healthcare (OR 10.2), being diagnosed before HET-law (OR 4.89), longer diagnostic delay (OR 1.26), and older age at onset (OR 1.05) were associated with a higher risk of PI>0.2, while current HET (OR 0.39) was a protective factor. Diagnosis before HET-law (OR 7.59), public-healthcare (OR 6.49), male sex (OR 2.56), longer disease duration (OR 1.2) and older age at onset (OR 1.1) were associated with a higher risk of Progressive MS. Public-healthcare (OR 5.54), longer disease duration (OR 1.14) and older age at onset (OR 1.08) were associated with a higher risk of EDSS ≥6.0 while current treatment with HET had a trend as being a protective factor (OR 0.44, p = 0.05). CONCLUSION: MS severity is impacted by non-modifiable factors such as sex and age at onset. Interventions focused on shortening diagnostic delay and encouraging early access to high-efficacy therapies, as well as initiatives that may reduce the disparities inherent to lower socioeconomic status, may improve outcomes in people with MS.
RESUMO
We report six patients with anti-LGI1 associated epilepsy. Two patients presented with new-onset generalized tonic-clonic seizures, four developed faciobrachial dystonic seizures and two piloerection. All patients had significant cognitive complaints at the time of diagnosis. All patients described seizure reduction during the first week of carbamazepine, and seizure freedom was obtained at a median of 13â¯days (range 7-22), sustained after the initiation of immunosuppression. Median time from symptom onset to carbamazepine initiation was 164â¯days (range 38-206â¯days). We discuss the particular seizure response to sodium channel blocking antiepileptic drugs, alone or associated with immunosuppression in this antibody mediated seizures.

We report the case of a 25-year-old woman who developed temporal lobe epilepsy associated with systemic lupus erythematosus (SLE). Serum and cerebrospinal fluid samples showed high titers of anti-ribosomal P (anti-P) antibodies with negative anti-NMDAR antibodies. She was receiving prednisone and azathioprine, with normalization of SLE serum markers, but without changes in titers of anti-P antibodies. No seizure control was achieved using valproic acid, levetiracetam and lamotrigine. However, she had a selective response to topiramate, an AMPAR blocker, maintained during 6â¯years of follow-up. We discuss the pathophysiology of this autoimmune epilepsy associated with high titer anti-P antibodies.

INTRODUCTION: Multiple sclerosis (MS), a neuroinflammatory and demyelinating disease, modifies the normal connectivity among different brain regions involved in specific functions. Functional magnetic resonance imaging (fMRI), based on local changes in oxygen level as a response to the increase in neural activity, provides an approach to neural connectivity and brain dynamics which give us an overview on visual, motor and cognitive dysfunction and their mechanisms. DEVELOPMENT: An advanced search was performed using PubMed. Terms 'fMRI', 'visual', 'motor', 'cognitive' and 'multiple sclerosis' included in title and abstract were considered. We focus on original articles available in English. Articles were included based on their abstracts, looking for those potentially useful for understanding functional changes in MS. An important amount of studies have used fMRI as a complementary tool in the study of MS and clinically relevant alterations compromising visual, motor and cognitive domains. Since the earliest stages of the disease, local activity, and global neural dynamics appear to be compromised. Even when functional performance is still preserved, a different recruitment of neural resources arises as a compensatory response to disconnection observed in the disease. CONCLUSIONS: The main findings of fMRI applied to MS are strongly related to the demyelinating nature of the disease and provide an adequate insight into the mechanisms that underlie functional alterations reported in this disease. fMRI also appears to be useful for studying disease evolution and response to treatment in MS and other disorders.
TITLE: Imagenes de resonancia magnetica funcional en el estudio de la esclerosis multiple.Introduccion. La esclerosis multiple (EM), una enfermedad neuroinflamatoria y desmielinizante, modifica la conectividad normal entre las diferentes regiones del cerebro involucradas en funciones especificas. La resonancia magnetica funcional (RMf), basada en cambios locales en el nivel de oxigeno como respuesta al aumento de la actividad neuronal, proporciona un enfoque a la conectividad neuronal y la dinamica cerebral que ofrece una vision general de la disfuncion visual, motora y cognitiva y sus mecanismos. Desarrollo. Se realizo una busqueda avanzada en PubMed considerando los terminos 'fMRI', 'visual', 'motor', 'cognitive' y 'multiple sclerosis' incluidos en el titulo y el resumen. La busqueda se centro en articulos originales disponibles en ingles, con enfasis en los utiles para comprender los cambios funcionales en la EM. Numerosos estudios han utilizado la RMf como una herramienta complementaria en el estudio de la EM y las alteraciones clinicamente relevantes de la afectacion visual, motora y cognitiva. Desde las primeras etapas de la EM, la actividad local y la dinamica neural global parecen estar afectadas. Incluso cuando el desempeño funcional aun se conserva, surge un reclutamiento diferente de los recursos neuronales como respuesta compensatoria a la desconexion observada en la enfermedad. Conclusiones. Los principales hallazgos de la RMf aplicada a la EM estan fuertemente relacionados con la naturaleza desmielinizante de la enfermedad y proporcionan una vision adecuada de los mecanismos subyacentes a las alteraciones funcionales. La RMf tambien parece ser util para estudiar la evolucion de la enfermedad y la respuesta al tratamiento en la EM y otros trastornos.

INTRODUCTION: The new 2015 criteria for neuromyelitis optica spectrum disorders (NMOSD) have been recently incorporated in the study of different international cohorts. AIM: To describe clinical-radiological characteristics and prognostic factors in patients with NMOSD according to the 2015 criteria. PATIENTS AND METHODS: Retrospective analysis of 36 patients diagnosed with NMOSD according to serologic AQP4 status (positive, negative, unknown and negative + unknown). Clinical and radiological characteristics were compared and possible disability prognostic factors were evaluated. RESULTS: AQP4 were positive in 7 patients, negative in 12 and unknown in 17. Age of presentation was 36.6 ± 16 years, with higher female proportion (4:1). Mean disease duration was 7.4 ± 7.6 years. Most frequent presenting symptoms were acute myelitis (61%), optic neuritis (33%) and area postrema syndrome (11%). Most frequent MRI lesion was longitudinally extensive transverse myelitis (75%). All patients received acute treatment during attacks, and preventive treatment was used in 81% (azathioprine and rituximab mostly prescribed). Median EDSS was 2.0 at the end of follow-up. No differences were observed in any of the variables comparing serologic status. Age of first attack was prognostic, with direct correlation with EDSS. First attack in < 30 years was protective, meanwhile > 50 years old patients had increased risk of disability. CONCLUSIONS: The 2015 criteria allow the description and classification of NMOSD patients within different cohorts. Age of first attack seems to be a prognostic factor for developing disability.
TITLE: Espectro de neuromielitis optica: descripcion de una cohorte segun los criterios diagnosticos de 2015.Introduccion. Los nuevos criterios diagnosticos de 2015 del espectro de neuromielitis optica (NMO) estan comenzando a utilizarse en diferentes poblaciones en el mundo. Objetivo. Describir las caracteristicas clinicorradiologicas y pronosticas de pacientes diagnosticados de NMO con los criterios de 2015. Pacientes y metodos. Analizamos retrospectivamente 36 pacientes diagnosticados de NMO con los actuales criterios. Se generaron cuatro grupos segun la serologia de antiacuaporina 4 (positivos, negativos, desconocidos y negativos mas desconocidos agrupados). Se compararon sus caracteristicas clinicorradiologicas y se evaluaron posibles variables pronosticas de discapacidad. Resultados. Encontramos siete pacientes seropositivos, 12 negativos y 17 desconocidos. La edad de inicio fue de 36 ± 16 años, con mayor proporcion de mujeres (4 a 1). La duracion de la enfermedad fue de 7,4 ± 7,6 años. Los sintomas iniciales mas frecuentes fueron mielitis (61%), neuritis optica (33%) y sindrome del area postrema (11%). La lesion mas frecuente en la resonancia magnetica fue la mielitis longitudinalmente extensa (75%). Todos los pacientes recibieron tratamiento agudo, y el preventivo se utilizo en el 81%; la azatioprina y el rituximab fueron los que mas se usaron. La mediana de la Expanded Disability Status Scale (EDSS) fue de 2 al final del seguimiento. No hubo diferencias significativas en las variables clinicorradiologicas entre los distintos grupos de pacientes. La edad de inicio fue pronostica y presenta correlacion directa con la EDSS. El inicio antes de los 30 años fue protector y, despues de los 50 años, un factor de riesgo para mayor discapacidad. Conclusiones. Los actuales criterios permiten describir diferentes cohortes. La edad de inicio parece ser un factor pronostico para desarrollar discapacidad.

OBJECTIVES: Lactoferrin (LF) is a breast milk glycoprotein with protective effects against neonatal infections, mainly in premature and low-birth-weight (LBW) neonates. The aims of this study were to determine LF concentration in breast milk of mothers of LBW infants during the first 2 months postpartum, and to identify the factors associated with LF concentration. STUDY DESIGN: Prospective study conducted as a part of an ongoing clinical trial in three Neonatal Units in Peru. We included 346 mothers of neonates with a birth weight <2000 g. We measured LF concentration in four stages of lactation using a commercial enzyme-linked immunosorbent assay kit. Multivariate analysis was performed to assess the association between maternal and neonatal factors, and LF concentration. RESULTS: We collected 695 milk samples. LF mean concentration±standard deviation was 14.92±7.96 mg ml-1 in colostrum (n=277), 10.73±5.67 in transitional milk (n=55), 10.34±6.27 at 1 month (n=259) and 8.52±6.47 at 2 months (n=104). There was a significant difference in LF concentration between different stages of lactation (P<0.001). Mothers with higher LF concentration in colostrum had higher values in the following 2 months. High maternal income and multiple gestation were significantly associated with higher LF levels; in contrast, maternal peripartum infections and male neonatal gender were associated with lower LF levels. CONCLUSIONS: LF concentration in breast milk of mothers of LBW infants was high and remained elevated even at 1 and 2 months postpartum. LF concentration in colostrum was higher in mothers with higher income and multiple pregnancies, and lower in mothers with peripartum infections.

BACKGROUND: Andrographis paniculata (A. paniculata), a medicinal plant, has shown anti-inflammatory, neuroprotective and antifibrotic effects in animal models as well as clinical efficacy in different studies, including an anti-fatigue effect in autoimmune diseases such as rheumatoid arthritis. In multiple sclerosis (MS), fatigue is rated as one of the most common and disabling symptoms. In the present trial, we investigated the effect of A. paniculata on relapse rate and fatigue in relapsing-remitting MS (RRMS) patients receiving interferon beta. METHODS: A randomised double-blind placebo-controlled trial assessed the effects of 170 mg of A. paniculata dried extract tablet b.i.d. p.o. on relapse rate and fatigue using the Fatigue Severity Scores (FSS) over 12 months in RRMS patients receiving interferon. The Expanded Disability Status Scale (EDSS) score, inflammatory parameters and radiological findings were also investigated. Twenty-five patients were enrolled, and twenty-two patients were ultimately analysed and randomised to the active or placebo group. RESULTS: Patients treated with A. paniculata showed a significant reduction in their FSS score as compared to the placebo, equivalent to a 44 % reduction at 12 months. No statistically significant differences were observed for relapse rate, EDSS or inflammatory parameters, with a trend in reducing new lesions among the A. paniculata group. One patient in the A. paniculata group presented with a mild and transient skin rash, which was alleviated with anti-histamine treatment for three weeks. CONCLUSION: A. paniculata was well tolerated in patients and no changes in clinical parameters were observed. A. paniculata significantly reduces fatigue in patients with RRMS receiving interferon beta in comparison to placebo and only interferon beta treatment.

El síndrome de dolor patelofemoral puede ser definido como dolor retropatelar o peripatelar resultante de cambios físicos y bioquímicos en la articulación patelofemoral. En ortopedia, las causas más comunes serían el sobreuso, el mal alineamiento patelofemoral y el trauma. Presentamos un caso del uso de radiofrecuencia pulsada selectiva de los nervios patelares, medial y lateral, para el tratamiento del dolor patelofemoral postraumático crónico. La radiofrecuencia pulsada puede ser una opción mínimamente invasiva para el tratamiento del síndrome de dolor patelofemoral postraumático...
Patellofemoral pain syndrome can be defined as retropatellar or peripatellar pain resulting from physical and biochemical changes in the patellofemoral joint. In orthopaedics, the most common causes include overuse, patellofemoral malalignment, and trauma. The case is reported of chronic post-traumatic patellofemoral pain syndrome treated with pulsed radiofrequency of both the medial and lateral patellar nerves. Pulsed radiofrequency might be a minimally invasive option for treatment of post-traumatic patellofemoral pain syndrome...

INTRODUCTION: Glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency) is the most common red blood cell (RBC) enzyme disorder. The decrease as well as the absence of the enzyme increase RBC vulnerability to oxidative stress caused by exposure to certain medications or intake of fava beans. Among the most common clinical manifestations of this condition, acute hemolysis, chronic hemolysis, neonatal hyperbilirubinemia, and an asymptomatic form are observed. OBJECTIVE: To analyze the case of a child who presented hemolytic crisis due to favism. CASE REPORT: A 2 year and 7 month old boy with a history of hyperbilirubinemia during the newborn period with no apparent cause, no family history of hemolytic anemia or parental consanguinity. He presented a prolonged neonatal jaundice and severe anemia requiring RBC transfusion. An intake of fava beans 48 h prior to onset of symptoms was reported. G6PD qualitative determination was compatible with this enzyme deficiency. CONCLUSION: G6PD deficiency can be highly variable in its clinical presentation, so it is necessary to keep it in mind during the diagnosis of hemolytic anemia at any age.

OBJECTIVE: Our aim was to assess the contribution of depression to cognitive impairment in patients with systemic lupus erythematosus (SLE). METHODS: Clinical features, education, age, and Hospital Anxiety and Depression Scale (HADS) were evaluated in 82 patients with SLE and 22 healthy controls, all Chilean women. The Cambridge Neuropsychological Test Automated Battery (CANTAB eclipseTM) assessing attention, spatial memory, and learning and executive function domains was applied. Cognitive deficit definition: a cut-off for definite impairment was defined as a score below -2 standard deviations in at least one outcome measure in two or more domains. ANCOVA with stepwise selection evaluated influences of health status (SLE or control), age, education, and HADS depression and anxiety scores on cognitive outcomes. To avoid overfitting, a shrinkage method was performed. Also, adjusted p-values for multiple comparisons were obtained. RESULTS: Cognitive deficit affected 16 (20%) patients, and no controls (p=0.039). Median HADS depression score in SLE patients was 6 (range 0-19) and in controls was 0 (0-19), p<0.001). ANCOVA and shrinkage models showed that worse cognitive performance in sustained attention and spatial working memory tests was explained by the presence of SLE but not depression, whereas depression only affected a measure of executive function (I/ED Stages completed). CONCLUSION: Depression has a limited role in cognitive impairment in SLE. Impairments in sustained attention and spatial working memory are distinctly influenced by yet-unknown disease-intrinsic factors.

Introducción: La deficiencia de la glucosa 6-fosfato deshidrogenasa (G6PD) es el trastorno enzimático más frecuente del glóbulo rojo (GR). Tanto la disminución como la ausencia de la enzima aumentan la vulnerabilidad del GR al estrés oxidativo provocado por algunos fármacos o la ingesta de habas. Sus manifestaciones clínicas más frecuentes son hemolisis aguda, hemolisis crónica, hiperbilirrubinemia neonatal, y una forma asintomática. Objetivo: Presentar el caso de un niño que debutó como crisis hemolítica debida a favismo. Caso clínico: Varón 2 años 7 meses con antecedente de hiperbilirrubinemia en el período neonatal sin causa evidente, sin historia familiar de anemia hemolítica ni de consanguinidad paterna. Debutó con un cuadro de ictericia y anemia severa que requirió transfusión de GR. Como antecedente anamnéstico se detectó la ingesta de habas 48 h previo al inicio de los síntomas. La determinación cualitativa de G6PD fue compatible con deficiencia de esta enzima. Conclusión: La deficiencia de G6PD puede ser muy variable en su expresión clínica, por lo cual es necesario tenerla presente dentro del diagnóstico diferencial de las anemias hemolíticas a toda edad.

Lower limb lymphorrhea secondary to a surgical procedure is a rare but difficult-to-solve complication. In lower limb, this entity is frequently associated with vascular procedures around the inguinal area. We report on a case of a knee lymphocutaneous fistula secondary to a knee revision arthroplasty. To our knowledge, no previous reports regarding this complication have been published.
RESUMO
Limited data exist on the effect of clinical trial participation on sexual behavioural change. Two hundred female sex workers working in Lima, Peru received human papillomavirus (HPV) vaccine in either the standard (0, 2, 6 months) or modified (0, 3, 6 months) schedule. Participants received comprehensive screening and treatment for sexually transmitted infections (STIs), counselling on safe sex practices, education about HPV and the HPV vaccine, contraceptives (oral and condoms) and family planning at each visit. We assessed vaccine completion rates, change in sexual practices, and changes in HPV knowledge before and after participation in the vaccine trial. There were high rates of vaccine completion, 91% overall. The estimated number of reported new and total clients over a 30-day period decreased significantly (P < 0.001). Knowledge about HPV and HPV-related disease increased among all participants. In addition, all participants listed at least one preventive strategy during the month 7 follow-up survey.

INTRODUCCIÓN: La nefropatía diabética es una complicación relevante de la Diabetes Mellitus. Por esto, la American Diabetes Association (ADA) recomienda la determinación de la velocidad de filtración glomerular (VFG) como screening de nefropatía. Existe una fórmula, la MDRD (Modification of Diet in Renal Disease), que permite hacer una estimación bastante exacta dela VFG. La utilización de ésta ha sido comparada permanentemente con la Cockcroft-Gault. OBJETIVO: comparar ambas fórmulas para la VFG en la realidad local. MATERIAL Y MÉTODO: se realizó un estudio retrospectivo sobre 243 pacientes, seleccionados al azar, de un total de 1.057 pacientes diabéticos tipo 2 registrados en el Plan de Salud Cardiovascular en el CESFAM San Rafael de la comuna La Pintana que contaban con medición seriada de Creatinina plasmática en sus controles periódicos. Se consideraron los valores de creatinina plasmática más recientes tomados en el período Enero 2010-Octubre 2011 y obtuvimos la VFG aplicando ambas fórmulas. RESULTADOS: del total de pacientes seleccionados, 158 fueron mujeres (65 por ciento) y 85 hombres (35 por ciento), con una media de edad de 53 años (DE 8,08). La VFG media estimada con MDRD fue de 89 ml/min/1,73 m2 (DE 21) y con la Cockcroft-Gault fue de 108 ml/min (DE 32), p<0,001. Realizamos un estudio de correlación entre ambas fórmulas. DISCUSIÓN: ambas mostraron correlación aceptable para estimar la VFG, aunque en pacientes obesos las estimaciones de VFG fueron más elevadas con Cockcroft-Gault que con MDRD. Por otro lado, en pacientes añosos la tendencia fue a que la fórmula MDRD diera estimaciones más altas.
INTRODUCTION: Diabetic Nephropathy is a significant complication of Diabetes Mellitus. Thats why, the American Diabetes Association (ADA) recommended for screening the determination of the glomerular filtration rate (GFR). MDRD (Modification of Diet in Renal Disease), is a formula which allows a very exactly estimation of GFR. Permanently, it had always been compared with Cockcroft-Gault formula. OBJECTIVE: Compare both formulas in the local reality. MATERIAL AND METHOD: It was done a retrospective studio over 243 patients, randomly selected, of a total of 1,057 type 2 diabetes patients registered in Cardiovascular program of San Rafael CESFAM that had serial measurement of plasmatic creatinine in their periodic controls. It was considered the most recent values of plasmatic creatinine taken between January 2010 October 2011. RESULTS: Of the patients selected, 158 women (65 percent) and 85 men (35 percent), with average age of 53 years (SD 8,08), the GFR estimated with MDRD was of 89 ml/min/1.73 m2 (SD 21) and 108 ml/min (SD 32) for Cockcroft-Gault formula, p<0.001. We realized a correlation studio between both formulas. DISCUSSION: Both formulas demonstrated an acceptable correlation to estimated GFR, although obese patients had higher estimations with Cockcroft-Gault formula, on the other side, elderly patients had elevated results with MDRD.

Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infection. Questionnaires were administered to 200 FSWs aged 18-26 years in Lima, Peru, to gather risk behaviours, and cervical swab samples were collected for Pap smears and HPV DNA testing as part of a longitudinal study. Participants reported a median of 120 clients in the past month, and 99.2% reported using condoms with clients. The prevalence of any HPV in cervical samples was 66.8%; 34 (17.1%) participants had prevalent HPV 16 or 18, and 92 (46.2%) had one or more oncogenic types. Fifteen women had abnormal Pap smears, 13 of which were HPV DNA positive. Fewer years since first sex was associated with oncogenic HPV prevalence in a model adjusted for previous sexually transmitted infection (STI) status and condom use with partners (prevalence ratio = 0.77, 95% confidence interval [CI] = 0.60-0.97). Our data confirm the high rates of HPV transmission among FSWs in Peru, highlighting the need for early and effective strategies to prevent cervical cancer.

Few data exist on oral human papillomavirus (HPV) prevalence in female sex workers (FSWs). Information regarding oral sex practices of 185 Peruvian FSWs, 18-26 years of age, was obtained via survey and compared with HPV testing results of oral rinse samples. Oral HPV prevalence was 14/185 (7.6%); four (28.9%) HPV genotypes were carcinogenic. One hundred and eighty-two participants reported having had oral sex; 95% reported condom use during oral sex with clients and 9.5% with partners. Women who had oral sex more than three times with their partners in the past month were more likely to have oral HPV than women who had oral sex three times or less (P = 0.06). Ten (71.4%) women with oral HPV were HPV-positive at the cervix; conversely 8.3% of women with cervical HPV were HPV-positive in the oral cavity. The prevalence of oral HPV was relatively low, considering the high rates of oral sex practiced by these women.

Los pacientes, como seres humanos determinados en su estructura que son, no pueden distinguir en la experiencia entre ilusión y percepción, por tanto viven los distintos dominios de existencia como distintos dominios de realidad que configuran distintos dominios explicativos, que surgen de explicar su experiencia con elementos de su experiencia. Para ellos, la percepción de la calidad de servicio es vivida como un dominio de realidad personal, realidad que es una construcción personal, existiendo tantas realidades como pacientes que perciben su experiencia con elementos de su experiencia, y cuyas distinciones que la validan no son necesariamente consensuadas. La gestión sanitaria debe abandonar la idea de que es posible construir una calidad de servicio objetiva, para poder avanzar en construir estrategias efectivas de comunicación y consenso de criterios comunes de distinción de calidad de servicio, para lograr efectiva satisfacción y lealtad de los pacientes(AU)
Patients as human beings determined by their structure cannot, while having an experience, distinguish between an illusion and reality, therefore they experience the different domains of existence and the different domains of reality. For them, the perception of service quality is experienced as a personal domain of reality, and this reality is a personal construction, generating as many realities as patients perceiving their experience with elements of their experience, whose distinctions that validate it are not necessarily shared or agreed. Health management must abandon the idea in that it is possible to build an objective quality service, to be able to make progress in building effective communication strategies and common consenus criteria for a quality service of distinction, in order to achieve effective satisfaction and patient loyalty(AU)

OBJECTIVE: To evaluate the prevalence of and the associated factors for metabolic syndrome (MS) among Latin American HIV-infected patients receiving antiretroviral therapy (ART) using baseline data from the RAPID II study. METHODS: A longitudinal study to evaluate the metabolic profile, cardiovascular disease (CVD) risk and associated treatment practices to reduce this risk has been conducted in seven Latin American countries (the RAPID II study). Adult HIV patients with at least six months of RT were enrolled. MS was defined following ATP-III criteria. Demographic and anthropometric data, serum biochemical and clinical parameters were compared in patients with and without MS using bivariate and multivariate analysis. RESULTS: A total of 4,010 patients were enrolled, 2,963 (74%) were males. Mean age (SD) was 41.9 (10.0) years. The prevalence of MS was 20.2%. Females had higher prevalence of MS than males (22.7% vs. 19.4%, p = 0.02). MS was driven by high triglycerides, low HDL-cholesterol and high blood pressure (HBP). Patients with MS had higher 10 year CVD risk: 22.2% vs. 7.4%, p < 0.001. Age (OR: 1.05 per year), female gender (OR: 1.29), family history of CVD (OR: 1.28), CD4 cell count (OR: 1.09 per 100 cell increase), and protease inhibitor based-ART (OR: 1.33) correlated with MS in the multivariate analysis. CONCLUSIONS: Prevalence of MS in this setting was similar to that reported from developed countries. MS was driven by high triglycerides, low-HDL and HBP, and it was associated with higher risk of CVD. Traditional risk factors, female gender, immune reconstitution, and protease inhibitor based-ART correlated with MS.

OBJECTIVE: Determine the prevalence of metabolic abnormalities (MA) and estimate the 10-year risk for cardiovascular disease (CVD) among Latin American HIV-infected patients receiving highly active anti-retroviral therapy (HAART). METHODS: A cohort study to evaluate MA and treatment practices to reduce CVD has been conducted in seven Latin American countries. Adult HIV-infected patients with at least one month of HAART were enrolled. Baseline data are presented in this analysis. RESULTS: A total of 4,010 patients were enrolled. Mean age (SD) was 41.9 (10) years; median duration of HAART was 35 (IQR: 10-51) months, 44% received protease inhibitors. The prevalence of dyslipidemia and metabolic syndrome was 80.2% and 20.2%, respectively. The overall 10-year risk of CVD, as measured by the Framingham risk score (FRF), was 10.4 (24.7). Longer exposure to HAART was documented in patients with dyslipidemia, metabolic syndrome and type 2 diabetes mellitus. The FRF score increased with duration of HAART. Male patients had more dyslipidemia, high blood pressure, smoking habit and higher 10-year CVD than females. CONCLUSIONS: Traditional risk factors for CVD are prevalent in this setting leading to intermediate 10-year risk of CVD. Modification of these risk factors through education and intervention programs are needed to reduce CVD.
