ANCA-associated vasculitis is a heterogeneous group of rare autoimmune conditions of unknown cause. Clinical characteristics and prognostic factors were analyzed in 47 patients 20 (42.5%) with granulomatosis with polyangiitis, 17 (36.2%) with microscopic polyangiitis, 6 (12.8%) with renal-limited vasculitis, and 4 (8.5%) with eosinophilic granulomatosis with polyangiitis. Mean age at diagnosis was 53.5 ± 16.5 years and the median of BVAS (Birmingham Vasculitis Activity Score) was 14 (4-42). The most frequent clinical manifestations were general in 44 (93.6%), renal in 30 (63.8%) and respiratory in 28 (59.6%). All received corticosteroids at the beginning of treatment. Intravenous cyclophosphamide was associated in 20 (42.5%) and oral route in 14 (29.8%); azathioprine in 3 (6.4%) and rituximab in 2 (4.2%). At a median follow-up of 35.5 months (range 0.14-234), 21 relapses were recorded in 14 patients. Overall mortality was 3.5 deaths per 100 patient-year in the whole group. Those over 55 years old, the presence of alveolar hemorrhage, those with FFS (Five Factor Score) of 2, and patients with MPA had poor prognosis. Renal involvement, ANCA pattern and BVAS were not associated to a poorer prognosis.Cardiovascular disorders represent the leading cause of death in dialysis patients. Alterations of bone and mineral metabolism (BMM) and vascular calcifications play a fundamental role in it. The objective of this study was to evaluate the predictive role on cardiovascular mortality of the measurement of biomarkers of BMM and vascular calcifications. A prospective cohort study was performed. All prevalent patients on chronic dialysis in September 2009 at our institution, who completed the total of the complementary studies, were studied. BMM biomarkers were measured (FGF 23, fetuin A, PTH, calcium and phosphorus) and the vascular calcifications were evaluated using the Kauppila and Adragao scores. Follow-up was carried out until 1/1/2019, death or transplant. Of the 30 patients included, 7 (23.3%) died due to cardiovascular causes. The follow-up time was 44.1 ± 30.4 (range = 1.4-112) months. The Adragao score was the only predictive variable of long-term cardiovascular mortality (area under the curve = 0.82; 95% CI 0.64-0.94; p less then 0.001). The best cut-off point was 5 (sensitivity = 85.7%; specificity = 78.3%). It was also an independent risk factor for cardiovascular mortality adjusted for age, diabetes mellitus, coronary heart disease, aortic calcifications, time spent on dialysis and follow-up time (adjusted OR = 1.77; 95% CI = 1.06-2.96; p = 0.028). The vascular calcifications quantified from the Adragao score were the only independent predictor of long-term cardiovascular mortality. This score represents a simple, useful and superior tool to the biomarkers of BMM.The epidemiology of pulmonary hypertension (PH), especially pulmonary arterial hypertension (PAH), has not been evaluated in our country, therefore there is no reference parameter to establishing the representativeness of this information in the national order. This registry represents the first collaborative effort to provide a knowledge base of this disease, including 5 scientific societies that represent different specialties (pediatrics, rheumatology, pulmonology and cardiology) with data from 23 Argentine provinces. These efforts involved five societies of various adult (cardiology, rheumatology, and pulmonology) and pediatric (cardiology) specialties. Subjects were grouped (1-5) in accord with the 2013 Nice classification. A total of 627 patients (mean age, 50.8 ± 18 years; women, 69.2%) were recruited. Incident cases accounted for 53%. Functional class III-IV accounted for 69% at time of diagnosis and 33.4% at time of inclusion. Distributions in groups 1-5 were 63.6%, 15.9%, 8.3%, 9.7%, and 2.4%, respectively. Treatment consisted of diuretics (51.2%), mineralocorticoid receptor antagonists (44.7%), digoxin (16.6%), anticoagulants (39.2%), renin-angiotensin antagonists (15.5%), beta blockers (15.6%), and calcium channel blockers (8%). Rates of specific therapies usage in PAH vs. non-PAH group were 80.5% vs. 40.8% (phosphodiesterase-5 inhibitors 71% vs. 38.6%; endothelin receptor antagonists 54.4% vs. 14.5%; prostanoids 14.3 vs. 3.1%; all p less then 0.001). Three-year survival in PAH and non-PAH differed significantly (82.8% vs. 73.3%; p = 0.001). In the Argentine RECOPILAR registry, the clinic-epidemiologic profile was that of advanced-stage disease. Diagnostic workups and therapeutics interventions, including use of specific therapy for PAH, were consistent with current recommendations. Despite delays in diagnosis, survival was aligned with other contemporary registries.Cardiovascular mortality (CVM) has become the major contributor to overall Fabry disease (FD) mortality in the enzyme replacement therapy (ERT) era. Our objectives were to describe causes and potential predictors of mortality in FD adult patients in Argentina, and to assess risk of major adverse cardiovascular events (MACE) in the ERT era. We retrospectively studied 93 consecutive patients treated with alphagalactosidase A (median follow up 9.5 years from start of ERT). Mean age at ERT starting was 35 ± 16.3 years. Prevalence of cardiomyopathy and renal disease reached 47% and 41%, respectively. Eleven subjects (11.8%, 95% CI 5-18%) died during follow up (1.24/100 patient-years). Mean overall survival was 71 years (95% CI 66-75 years). Seven cases were considered as CVM; main causes were sudden death and stroke. Risk of MACE was 14% (95% CI 6.9-21.1%; 1.47 events/100 patient-years from start of ERT). All but 2 subjects had at least one comorbid cardiovascular risk factor; however, 86% of patients remained free of MACE during follow-up. CVM remained low and our study was underpowered for detection of predictors of mortality, but it is worth noting that age at diagnosis and ERT starting, left ventricular mass index and renal disease trended to correlate with CVM. Prevalence of hypertension, diabetes and dyslipidemia were lower in FD patients when compared to population level data. As in the Argentinean general population, CVM was the leading cause of mortality among this cohort of consecutive FD patients treated with agalsidase alfa.Hydatidosis - caused by the parasite Echinococcus granulosus - is a zoonosis endemic to the province of Santa Cruz, associated with areas of livestock production. Once infected, man may remain asymptomatic for a prolonged period but the disease has an important impact on public health owing to the complexity and costs of its treatment. This study aimed at assessing the prevalence of environmental E. granulosus infection in rural and peri-urban areas of the town of Los Antiguos, through the detection of antigens in scattered canine feces, and to identify risk factors for transmission. From May-2016 to April-2017, 38 peri-urban and rural farms, defined as "epidemiological units", were visited; 144 samples of canine feces were analyzed with the copro-ELISA technique. Rural settlers were enrolled in an epidemiological survey on cultural patterns related to hydatidosis. An environmental contamination index of 17.3% was found and 44.7% of the epidemiological units were positive. Risk practices were found, such as domiciliary slaughter (34.2%), canine feeding with raw viscera (52.6%), and lack of dog deworming (86.8%). In turn, about half of the surveyed population ignored the modes of transmission of the infection and the measures to prevent it. This work shows a high infection index in the area and establishes a baseline for future comparisons. It also reinforces the need to implement education, prevention, and control activities at the local level - according to national program guidelines - in order to reduce the prevalence of environmental contamination of the disease.A retrospective-observational analytical study was carried out to evaluate the epidemiology of catheter-related bloodstream infections (CRBSI) in 773 adult patients hospitalized in the intensive care unit (ICU) of the Hospital Alemán of Buenos Aires, Argentina, between 1 December 2018 and 30 June 2020. During the study period, the incidence of CRBSI was 8.7 cases per 1000 catheter days. The occurrence of CRBSI was found associated with a poor clinical evolution, as evidenced by a stay in the ICU significantly longer than the stay of patients without CRBSI (median 21.5 days vs. 4 days, p less then 0.001). CRBSI-associated mortality was not statistically higher (24% vs. 20%, OR 1.26 [0.61-2.63]). Gram-positive bacteria were the most frequently identified microorganisms (73%), being Staphylococcus epidermidis the most frequent (40%). Of the 47 isolates of microorganisms surveyed, 8 (17%) were multi-resistant germs. The permanence time of the catheter was identified as a risk factor for developing CRBSI (OR 1.10 [1.05 - 1.15], p less then 0.001) in a multivariate analysis. In this analysis, the risk of infection was not influenced by the anatomical site of insertion of the catheter, the ward where the procedure was performed (ICU vs. operating room/external ward), the skill of the medical practitioner, or the use of ultrasound to guide vascular accesses. We conclude that CRBSIs are a frequent complication in our department with relevant clinical consequences. Knowing the epidemiology and the problems of each service allows programming interventions aimed to correct specific public health problems.Chagas disease is endemic in Latin America and remains a regional problem despite improvements in environmental health conditions that have helped to control its transmission. To know more about its prevalence in heart disease patients, we carried out a survey in our national (El Salvador) reference hospital. We reviewed the Chagas Lab's records 2013-2015 to find out how many of the patients admitted to the Hospital's Heart Unit were serologically positives for Trypanosoma cruzi infection and which the associated diagnoses were. A total of 1472 patients were tested along the 36-month study period. Out of 557 (37.8%) patients with positive serology for Chagas infection, 97 (17.4%) were eventually admitted to the Heart Unit. Among these 97 Chagas infected patients with heart disease, 40 (41.2%) met the criteria for permanent pacemaker placement, while only 13 of 191 (6.8%) patients with non-chagasic heart disease met these criteria. The frequency of heart atrioventricular block associated with Trypanosoma cruzi infection was higher than frequencies reported in South American studies.An age difference > 5 years in the choice of sexual partner may constitute a risk factor for sexually transmitted infections (STIs), including HIV infection. A sexual and reproductive health survey was carried out on people who consulted for STIs or HIV serology in two health centers in Buenos Aires suburbs, with the aim of providing information for the design of prevention measures and to know if in this area there is an association between the maximum age difference (MAD) in the choice of sexual partner and the acquisition of HIV and/or STIs. A total of 120 patients consulted, 90% (108) performed serology, resulting 15 of them (13.9%) infected with HIV and 46 (42.6%) with syphilis. The MAD with the partner was = 5 years in 65 (54.6%) and > 5 years in 54 (45.4%) of 119 who answered the survey. Men who have sex with men reported a MAD > 5 years more frequently (p = 0.022 OR 3.59). The risk for HIV increased 9% for each year of age difference with the sexual partner (OR 1.093). The percentage of urethritis cases was significantly lower in the age group = 25 years.
