Leucemia de linfocitos grandes granulares como complicación de artritis reumatoide

Large granular lymphocyte leukemia is a rare entity belonging to same spectrum of diseases than Felty's syndrome, which might occur in patients with long-standing rheumatoid arthritis. It is clinically characterized by persistent neutropenia and recurrent bacterial infections associated with the presence in both peripheral blood and bone marrow of clonal expansion of atypic lymphocytes with a cytotoxic T cell phenotype, or less frequently an NK-cell phenotype, as well as splenomegaly. It is more frequently diagnosed in seropositive rheumatoid arthritis, with significant structural damage, extra-articular manifestations and persistently elevated values of ESR, despite them havubg low inflammatory joint activity. We report the case of a 70 year old male with a long-standing rheumatoid arthritis, who developed septic shock secondary to prosthetic hip infection by Salmonella spp. He showed persistent neutropenia, and an aberrant monoclonal T cell population was detected in both peripheral blood and bone marrow, consistent with large granular lymphocyte leukemia.     

Frecuencia de ANA/DFS70 en familiares de pacientes con artritis reumatoide comparados con pacientes con artritis reumatoide y población sana y su asociación con el estado de salud

IntroductionDFS70 ANAs have attracted interest due to their frequency in individuals with no clinical evidence of systemic autoimmune rheumatic disease, groups with genetic risk for rheumatoid arthritis (RA) were not assessed.ObjectiveTo determine the frequency of ANA and DFS70 ANA in blood relatives (BR) of people with RA compared to patients with early RA (ERA), and control individuals, and its association with health status.MethodologyA cross-sectional study with an analytical component. Sixty ERA patients, 60 BR and 120 control individuals paired by age and sex were studied. Hep2-ANA and DFS70 ANA were studied. The absolute and relative frequencies and associations were established using logistic regression models, with a significance level of 95%.Results43% ANA in ERA, 30% in BR, and 25.8% in control individuals 1:80. The fine dense granular pattern based on conventional Hep2 was found in 12.9% of the positive samples, and 1.66% of the total samples. There was no detection of DFS70 ANAs in patients with ERA. In ERA there was an association between the presence of ANA and inflamed joints (p = .02), CRP (p = .01), DAS28CRP (p = .03) and HAQ (p = .04). There was an association between ANA and elevated CRP (p = .05) in the BR. In the control individuals, there was an association between ANA and painful joints (p = 02). In DFS70 ANA individuals we observed an association between a normal ESR p = .032, BR (-), p = .044 and absence of painful joints, p = .039.ConclusionsThe frequency of DFS70 ANA in the groups studied was low, none of the patients with ERA was positive. The presence of DFS70 ANA was only confirmed in systemically healthy individuals.     

Estrategias de curación de la infección por VIH

The disadvantages of the long-term administration of antiretroviral therapy as well as the huge number of affected persons have placed the cure of HIV as a primary goal of Public Health. HIV may persist in the organism by at least four mechanisms: a latently infected cellular reservoir, the persistent replication of HIV in spite of ART, anatomic sanctuaries, and the immune dysfunction. Several strategies directed against these mechanisms have been developed. With all this, a complete eradication of HIV has been achieved in a patient using the transplantation of haemopoietic stem cells that were resistant to HIV-infection, and there are examples of functional cure either spontaneously (elite controllers) or after antiretroviral therapy (post-treatment controllers). However, no strategies have been successful in reducing the reservoir size, nor in achieving constant, uniform remissions. The failure of isolated strategies makes it likely that the combination of several of them may be the future solution.     

Validación de una versión en español del Health Assessment Questionnaire-II para la evaluación de la capacidad funcional en pacientes mexicanos con artritis reumatoide

ObjectiveTo evaluate the validity, reliability, and performance of the Health Assessment Questionnaire-II(HAQ-II) Spanish version questionnaire to measure physical function.MethodsA cross-sectional study of 496 patients with rheumatoid arthritis, distributed in 2 samples. The construct validity was evaluated employing the confirmatory factor analysis and the validity based on the relationship with other variables. Cronbach's alpha (α) and McDonald's omega (ω) coefficient were used to determine reliability. Item performance was analysed by fitting different models of item response theory.ResultsThe one-factor model presented a poor fit in the confirmatory factor analysis; an exploratory factor analysis was carried out, which suggested a 2-factor structure. The confirmatory factor analysis in the second sample confirmed that the second-order model had a good fit to the data. The general factor explained more than 70% of the variance. The reliability indices showed adequate internal consistency (α = .92-.95; ω = .88-.93). Ninety-three percent of the contrasting hypotheses about the relationship of the HAQ-II scores with other variables were confirmed, demonstrating their convergent, divergent, and known group validity. The multidimensional graduated response model was the one that best predicted person's interaction with the items.ConclusionThe Spanish version of the HAQ-II presents adequate validity and reliability for measuring Mexican patients’ physical function with rheumatoid arthritis.     

Evolución a largo plazo de la calidad de vida en pacientes con artritis reumatoide tratados con terapias biológicas

Objective

To analyze the changes in health-related quality of life (HRQoL) of patients with rheumatoid arthritis (RA) treated with biological therapies.

Impacto de una intervención de Atención Primaria en el programa de detección precoz de cáncer colorrectal

AimTo assess the effectiveness of a telephonic interview performed by primary care professionals among non-participants in the first round of the colorectal cancer early detection programme in the basic urban health area Guineueta in Barcelona, Spain.Patients and methodsThe Primary Healthcare Team of La Guineueta contacted people who did not respond to the invitation to the first round of the colorectal cancer early detection programme using a standardised telephone call protocol. We analysed the impact of the intervention based on participation and diagnosed disease.ResultsWe made 3,327 phone calls to 2,343 people. After the intervention the participation rate was 54.9%, which meant an increase of 5.7% with respect to the participation in the usual protocol for the programme (49.2%). The intervention allowed 5 cancers, 2 high-risk neoplasms and 8 low- and intermediate-risk lesions to be diagnosed. An average of 9 phone calls was necessary to achieve the participation of one additional person.DiscussionThe telephonic intervention performed by primary care professionals has significantly increased the population participation rate and the detection of neoplasms with respect to the usual colorectal cancer early detection programme protocol.

Osificación heterotópica de las piernas en un varón

Heterotopic ossification is an uncommon disorder that consists of deposition of ectopic bone outside the extraskeletal tissues. In the skin, it can be primary, in association with genetic syndromes, or be secondary to different disorders. The latter include subcutaneous ossification of the legs in chronic venousinsufficiency, an infrequent and unrecognized complication. We report the case of a patient with subcutaneous ossification of both legs secondary to venous insufficiency and review the literature.     

Infecciones de transmisión sexual en el contexto de una agresión sexual

Sexual violence is a worldwide problem with an impact on health that encompasses medical, legal and psychological aspects. Therefore the management of these patients must be multidisciplinary, and action protocols are compulsory. People who are victims of a sexual assault (SA) are at high risk of acquiring a sexually transmitted infection (STI), which must be prevented, diagnosed, treated and followed up post treatment, according to the established action protocol to prevent potential complications.
