Prevalence and risk factors of multidrug-resistant tuberculosis in Cubal, Angola: a prospective cohort study.

BACKGROUND: Although the Republic of Angola is one of the 14 countries figuring in the three high tuberculosis (TB) burden country lists, the true multidrug-resistant TB (MDR-TB) situation is unknown. MATERIAL AND METHODS: Patients aged 16 years with a diagnosis of pulmonary TB were prospectively enrolled from June 2014 to July 2015. Sputum samples were collected for culture and drug susceptibility testing in all patients, and for Xpert® MTB/RIF testing in all previously treated patients and in new patients whose sputum remained smear-positive after 2 months of treatment. RESULTS: A total of 422 patients were included; Mycobacterium tuberculosis was isolated in 308 sputum samples. The prevalence of MDR-TB was 8.0% (18/225) in new patients and 71.1% (59/83) in previously treated patients. Male sex (OR 2.95, 95%CI 1.35-6.44, P = 0.007), previous anti-tuberculosis treatment (OR 20.86, 95%CI 9.53-45.67, P < 0.001), presence of pleural thickening (OR 7.68, 95%CI 1.57-37.43, P = 0.012) and duration of illness >4 months (OR 3.34, 95%CI 1.45-7.69, P = 0.005) were independent risk factors for MDR-TB. CONCLUSIONS: The prevalence of MDR-TB in Cubal, Angola, was higher than estimated by the World Health Organization for Angola and one of the highest worldwide. Facilities to diagnose and treat MDR-TB are urgently needed in Angola.

Infectious encephalitis: utility of a rational approach to aetiological diagnosis in daily clinical practice.

In this study we attempt to assess the utility of a simplified step-wise diagnostic algorithm to determinate the aetiology of encephalitis in daily clinical practice and to describe the main causes in our setting. This was a prospective cohort study of all consecutive cases of encephalitis in adult patients diagnosed between January 2010 and March 2015 at the University Hospital Vall d'Hebron in Barcelona, Spain. The aetiological study was carried out following the proposed step-wise algorithm. The proportion of aetiological diagnoses achieved in each step was analysed. Data from 97 patients with encephalitis were assessed. Following a simplified step-wise algorithm, a definite diagnosis was made in the first step in 53 patients (55 %) and in 12 additional cases (12 %) in the second step. Overall, a definite or probable aetiological diagnosis was achieved in 78 % of the cases. Herpes virus, L. monocytogenes and M. tuberculosis were the leading causative agents demonstrated, whereas less frequent aetiologies were observed, mainly in immunosuppressed patients. The overall related mortality was 13.4 %. According to our experience, the leading and treatable causes of encephalitis can be identified in a first diagnostic step with limited microbiological studies. L. monocytogenes treatment should be considered on arrival in some patients. Additional diagnostic effort should be made in immunosuppressed patients.

Immunosuppression and Chagas disease; experience from a non-endemic country.

Reactivation of Chagas disease in the chronic phase may occur when immunosuppression is established, sometimes resulting in high parasitaemia and severe clinical manifestations such as meningitis and meningoencephalitis. Although this situation is being increasingly described, there is still scarce information. This retrospective observational study was performed in three Tropical Medicine Units of Barcelona (Spain) included in the International Health Programme of the Catalan Health Institute (PROSICS). The objective of the study was to describe epidemiological, clinical, microbiological, prognostic and therapeutic data from patients with Chagas disease and any kind of immunosuppressive condition attended in these three institutions from January 2007 to October 2014. From 1823 patients with Chagas disease attending these three centres during the study period, 38 (2%) had some kind of immunosuppressive condition: 12 patients had human immunodeficiency virus infection, 8 patients had neoplasia, 4 patients underwent organ transplantation and 14 patients had an autoimmune disease. Eight (21.1%) patients had cardiac involvement, and six (15.8%) patients had gastrointestinal involvement. Acute Trypanosoma cruzi infection was detected in two Spanish patients. Thirty-one (81.6%) patients received treatment with benznidazole, of whom 17 (54.8%) had some kind of adverse event. No patient had a severe manifestation or reactivation of Chagas disease. Patients with Chagas disease under immunosuppressive conditions are being increasingly described, especially in non-endemic countries. More information about this topic is required and international consensus in the diagnosis, treatment and follow up of these patients must be established to reduce the morbidity and mortality.

Prognostic value of glomerular filtration rate estimation equations in acute heart failure with preserved versus reduced ejection fraction.

AIMS: Renal function is an important prognostic factor in heart failure. The aim of this study was to compare the predictive value of estimated renal function calculated by the Chronic Kidney Disease-Epidemiology Collaboration equation (CKD-EPI) and the abbreviated Modification of Diet in Renal Disease (MDRD-4) equation for long-term all-cause mortality in patients admitted for acute decompensated heart failure (ADHF) with both preserved ejection fraction (HF-PEF) and reduced ejection fraction (HF-REF). METHODS AND RESULTS: We evaluated patients included in the Spanish National Registry of Heart Failure (RICA). RICA is a multicentre, prospective, cohort study that included patients admitted to the Internal Medicine units with ADHF. Estimated glomerular filtration rate (eGFR) was calculated with CKD-EPI and MDRD-4 equations. A total of 1805 patients admitted for ADHF were studied (52% women; median age 80 years, interquartile range 73.9-84.6 years); of these, 1044 (58%) had HF-PEF. eGFR values were lower with the CKD-EPI formula than with the MDRD-4 formula (51 ml/min/1.73 m(2) vs. 55.7 ml/min/1.73 m(2) ; p < 0.001). The two formulas provided independent prognostic information over long-term follow-up, in both HF-PEF and HF-REF patients. However, in HF-PEF patients, CKD-EPI equation was associated with a significant improvement in reclassification analyses (net reclassification improvement 6.78%; p = 0.009). CONCLUSIONS: In this clinical cohort of ADHF patients, eGFR as calculated by both the CKD-EPI and the MDRD-4 formulas offered similar prognostic information, irrespective of ejection fraction status, but in HF-PEF patients specifically, the CKD-EPI formula seems to improve clinical risk stratification as compared with MDRD-4.

Introduction on health recommender systems.

People are looking for appropriate health information which they are concerned about. The Internet is a great resource of this kind of information, but we have to be careful if we don't want to get harmful info. Health recommender systems are becoming a new wave for apt health information as systems suggest the best data according to the patients' needs.The main goals of health recommender systems are to retrieve trusted health information from the Internet, to analyse which is suitable for the user profile and select the best that can be recommended, to adapt their selection methods according to the knowledge domain and to learn from the best recommendations.A brief definition of recommender systems will be given and an explanation of how are they incorporated in the health sector. A description of the main elementary recommender methods as well as their most important problems will also be made. And, to finish, the state of the art will be described.

Clinical significance of antinuclear antibodies in malignant diseases: association with rheumatic and connective tissue paraneoplastic syndromes.

Our objective was to determine the prevalence of antinuclear antibodies (ANAs) in patients with malignancies and to investigate if their presence might be related with development of musculoskeletal symptoms or paraneoplastic rheumatic syndromes. Antinuclear antibodies were determined by indirect immunofluorescence on Hep-2 cells in 274 neoplastic patients and in a control group of 140 age-adjusted healthy subjects. Antinuclear antibody specificities (anti-DNA and anti-ENA) were investigated in patients with rheumatological symptoms and positive ANA. Antinuclear antibodies were detected in 76 of 274 (27.7%) patients with malignancies and in nine of 140 (6.4%) healthy subjects. Twenty patients reported paraneoplastic rheumatic symptoms or syndromes. Two of them developed clinical symptoms mimicking rheumatoid arthritis (rheumatoid-like arthropathy), one systemic lupus erythematosus (lupus-like syndrome), one dermatomyositis and four cutaneous vasculitides. Musculoskeletal symptoms and paraneoplastic rheumatic symptoms and syndromes were both more frequently observed in patients with positive ANA. Antinuclear antibody specificities were found in only two cases. We can conclude that there is an increased incidence of antinuclear antibodies in malignant conditions. Musculoskeletal symptoms and rheumatic paraneoplastic symptoms and syndromes seem to be more frequent in patients with cancer-related positive ANAs. The failure to find ANA specificities (anti-ENA, anti-DNA) in patients with malignancies and positive ANAs in our study may simply reflect molecular differences between the autoantigens involved in cancer and those characteristically involved in the systemic autoimmune diseases.

Churg-Strauss syndrome: outcome and long-term follow-up of 32 patients.

OBJECTIVES: To study the clinical spectrum and evolution of Churg-Strauss syndrome in order to assess the clinicopathological features of the disease, the response to treatment and the long-term outcome. METHODS: Thirty-two patients with proven allergic and granulomatous angiitis (Churg-Strauss syndrome) and followed up at a single institution were evaluated. They were recruited between 1977 and 1999 from internal medicine departments. Data were obtained retrospectively from medical files in 15 cases and prospectively, using a standardized form, for the remaining patients. RESULTS: All patients had asthma and hypereosinophilia. The lungs, skin and peripheral nervous system were the organs most frequently involved. Antineutrophil cytoplasmic antibodies with antimyeloperoxidase specificity (MPO-ANCA) were detected in 77.8% of tested patients but they were not useful for monitoring disease activity. Extravascular granulomas were rarely seen in tissue biopsies. Forty per cent of the patients were treated with steroids alone. Immunosuppressive agents were added to the treatment when severe neurological, cardiac or gastrointestinal involvement was present. The outcome and long-term survival were good. Clinical relapse was rare after the first year of therapy. Dysaesthesiae of the distal limbs, neurophatic pain and cardiac failure were the most frequent sequelae. CONCLUSIONS: Churg-Strauss syndrome is a rare disorder characterized by hypereosinophilia and systemic vasculitis occurring in patients with asthma and allergic rhinitis. Vasculitis commonly affects the lungs, skin and peripheral nervous system. Outcome and long-term survival is usually good with steroids alone or in combination with immunosuppressive agents. The syndrome has a low mortality rate compared with other systemic vasculitides.

[Scleroderma and pregnancy: obstetrical complications and the impact of pregnancy on the course of the disease]. / Esclerodermia y embarazo: complicaciones obstétricas y repercusión del embarazo en el curso de la enfermedad.

BACKGROUND: To describe the outcome of the pregnancy in patients with scleroderma. PATIENTS AND METHODS: Patients with scleroderma and control group were included in this retrospective study. Two groups were different in pregnant patients with scleroderma: pregnancy before scleroderma (A1) and pregnancy after scleroderma (A2). The presence of clinical problems during pregnancy and the outcome of scleroderma were collected in a questionnaire. Differences in the frequencies of complications were analyzed using the U Mann-Whitney, the chi-square or Fisher's exact test when necessary. RESULTS: The frequency of global fetal complications was increased in patients group, but there was no significantly increased frequency when variables were analyzed independently: number of births, miscarriages, fetal deaths, preterm births and low weight full term babies. There was no increased frequency of renal crisis, hypertension or eclampsia. Differences between diffuse and limited subsets were no observed. Improvement of scleroderma was seen in only 3 patients and worsening of skin thickening was experienced by 2 patients. CONCLUSIONS: The pregnant scleroderma patients are a group with high risk pregnancies and therefore well-supervised pregnancies are necessary.
