RESUMO
Back in January 2022, an EASL-Lancet Commission on the impact of liver disorders in the European region commissioned by the WHO demonstrated that this condition is, actually, the second leading cause of loss of labor years in Europe after ischemic heart disease (1). This is a very relevant piece of information since this is something that is going to impact the new generations of Europeans unless a significant change is made in public health policies. Despite the advances made over the last few years in hepatitis C virus clearance-understood as a significant reduction of morbidity and mortality associated with Hepatitis B and C viruses-there are still challenges ahead to improve liver health due to the high use of alcohol, and the inseparable triad obesity / diabetes mellitus / metabolic associated fatty liver disease. Also, access to healthcare for several population groups at risk of presenting higher rates of liver disease has become a problem.

OBJECTIVE: To know the transmission patterns of the acute infection by the hepatitisC virus at a time when we are close to its elimination. PATIENTS AND METHODS: A prospective descriptive clinical-epidemiological study of cases of acute HCV infection diagnosed between 2016 and 2020 was carried out in a reference hospital in the island of Gran Canaria. RESULTS: Twenty-two cases of acute HCV were diagnosed (10 primary infections and 12 reinfections). There was an increase in the incidence from 0.6 in 2016 and 2017 to 2.3 cases per 100,000 inhabitants in 2020. The median age was 46years. From these, 77.3% were men and 68.2% were HIV-positive. According to the risk factors, 54.5% had high-risk sexual practices, 83.3% were men who had sex with men (70% with a concomitant STI), 31.8% were drug users, 9.1% were women with neuropsychiatric disorders, and one woman (4.5%) had a previous surgical intervention. There were thirteen patients (40.9%) who presented symptoms and eleven out of the thirteen patients who were asymptomatic were HIV-positive. CONCLUSIONS: An increase in incidence was observed in the last years of the study and the main route of infection was high-risk sexual practice, mainly in men who have sex with men and who are HIV positive. Cases related to unsafe sex in other non-HIV groups are probably under-diagnosed. Microelimination strategies may not be sufficient to diagnose these cases, so in order to achieve elimination of the HCV the best strategy would be a population-based screening.

INTRODUCTION: In Spain, half of new HIV diagnoses are late and a significant proportion of people living with HIV have not yet been diagnosed. Our aim was to evaluate the effectiveness of an automated opportunistic HIV screening strategy in the hospital setting. METHODS: Between April 2022 and September 2023, HIV testing was performed on all patients in whom a hospital admission analytical profile, a pre-surgical profile and several pre-designed serological profiles (fever of unknown origin, pneumonia, mononucleosis, hepatitis, infection of sexual transmission, rash, endocarditis and myopericarditis) was requested. A circuit was started to refer patients the specialists. RESULTS: 6407 HIV tests included in the profiles were performed and 18 (0.3%) new cases were diagnosed (26.4% of diagnoses in the health area). Five patients were diagnosed by hospital admission and pre-surgery profile and 13 by a serological profile requested for indicator entities (fever of unknown origin, sexually transmitted infection, mononucleosis) or possibly associated (pneumonia) with HIV occult infection. Recent infection was documented in 5 (27.8%) patients and late diagnosis in 9 (50.0%), of whom 5 (55.5%) had previously missed the opportunity to be diagnosed. CONCLUSIONS: This opportunistic screening was profitable since the positive rate of 0.3% is cost-effective and allowed a quarter of new diagnoses to be made, so it seems a good strategy that contributes to reducing hidden infection and late diagnosis.
RESUMO
OBJECTIVE: This study describes the epidemiological, clinical and microbiological features of acute aseptic meningitis (AAM) in an adult population, and evaluates the impact of microbiological results on the clinical management of patients. PATIENTS AND METHODS: Cases of AAM were prospectively collected between 2007 and 2010 among immunocompetent patients over 14 years-old. Enteroviruses and herpes viruses were determined using nucleic acids detection in CSF. Demographic and clinical data were retrospectively collected from medical records. RESULTS: A total of 94 patients were included, of whom 84 were diagnosed with viral meningitis (VM). The annual incidence of VM ranged from 2.4 to 15.3 cases per 100,000 inhabitants. An aetiological diagnosis was obtained in 76.2% of the patients with VM, 55 enterovirus, 4 HSV-2, 3 VZV, one HSV-1, and one EBV. Forty five per cent of patients were admitted to hospital and 65.8% of them received antibiotic treatment. A positive result prompted immediate discharge of 80% of inpatients and discontinuation of antibiotic therapy in 94.1% of them. The median duration of admission to hospital in these patients was 2.8±2.9 days. Patients without available results during admission completed the antibiotic treatment, and the median hospital stay was 11.6±4.6 days. CONCLUSIONS: The annual incidence of AAM is variable. Enteroviruses were the main aetiological agent. Molecular tests revealed the aetiology in 76.2% of cases. Almost half of the patients required hospitalisation, and in these cases a positive result can lead to the immediate discharge of patients, and the diagnostic and therapeutic interventions can be reduced.

INTRODUCTION: Knowledge of acute hepatitis C infection (AHC) is important to design effective prevention and treatment strategies. The aim of this study was to determine the clinical and epidemiological features and outcomes of patients diagnosed with AHC. METHODS: A retrospective clinical-epidemiological study was carried out in adult patients diagnosed with AHC between 2000 and 2008 in our hospital. RESULTS: Sixteen patients were diagnosed. The most probable source of transmission was intravenous drug abuse in four patients, a percutaneous injury in three healthcare workers, a medical procedure in three patients and sexual contact in two patients. The source of infection was unknown in four patients. Diagnosis was based on acute clinical symptoms in eight patients, follow-up of healthcare injury in three patients and was fortuitous in five patients. Nine patients showed severe symptoms, while seven patients were asymptomatic or had mild symptoms. The four patients who received treatment were cured. Of the 12 patients that did not receive treatment, the disease became chronic in 58.3%. Progression to chronic disease was more frequent in patients without jaundice than in those with jaundice (85.7% vs 16.7%). CONCLUSIONS: Because medical procedures are still a risk factor for hepatitis C infection, active surveillance is required as well as compliance with prevention measures against parenteral transmission. The percentage of patients with jaundice who progress to chronic disease is low and consequently the start of treatment in these patients could be delayed according to their clinical course.

OBJECTIVE: Describe the epidemiological and clinical pattern of Bordetella pertussis infection (whooping cough) among hospitalised infants less than one year-old in a paediatric hospital in Gran Canaria. PATIENTS AND METHODS: A retrospective review of the patient hospital records was performed, and recording only those with a microbiological diagnosis of pertussis infection detected using polymerase chain reaction, from January 2008 to December 2016. RESULTS: A total of 110 patients were identified, of which 105 (95.4%) were less than 6 months-old, and 59.1% were males. The annual incidence of hospital admissions was estimated between 13.7 to 425.0 cases per 100,000 infants <12 months old, with 2peaks in 2011 and 2015. Household members were the main potential sources of infection. Main clinical features were pertussis cough associated with signs of catarrh, cyanosis, and lymphocytosis. Complications occurred in 15.4% of the patients (mainly pneumonia), but the outcome was favourable in all the cases. A lower age and non-vaccination were associated with an increased risk of developing complications (P<.05). Viral co-infection occurred in 31.6% of infants diagnosed with pertussis. CONCLUSIONS: The incidence of pertussis has increased in the last years in Gran Canaria, with a lower development of complications and mortality rates compared with the previous period. Lower age and non-vaccination status are considered risk factors for developing complications. Vaccination in pregnant women will probably lead to a decline in the incidence in the future, especially in infants younger than 6 months.

OBJETIVO: Describir el patrón epidemiológico y clínico de la infección por Bordetella pertussis (tosferina) en niños menores de un año hospitalizados en un hospital pediátrico de Gran Canaria. PACIENTES Y MÉTODOS: Se revisaron retrospectivamente las historias clínicas de los pacientes con diagnóstico microbiológico de infección por B. pertussis mediante reacción en cadena de la polimerasa, de enero de 2008 a diciembre de 2016. RESULTADOS: Se identificaron 110 pacientes, de los cuales 105 (95,4%) fueron menores de 6 meses y el 59,1% eran varones. La incidencia anual de hospitalización se estimó entre 13,7 y 425,0 casos por cada 100.000 lactantes menores de 12 meses, con 2 picos en 2011 y 2015. Los familiares cercanos fueron las principales fuentes de contagio potenciales. Las principales manifestaciones fueron la tos pertusoide asociada con signos catarrales, cianosis y linfocitosis. El 15,4% de los pacientes presentaron complicaciones (principalmente neumonía), pero la evolución fue favorable en todos los casos. La menor edad y la no vacunación se asociaron con un mayor riesgo de desarrollar complicaciones (p < 0,05). La coinfección viral ocurrió en el 31,6% de los pacientes diagnosticados de infección por B. pertussis. CONCLUSIONES: La incidencia de infección por B. pertussis ha aumentado en los últimos años en nuestra área, con un menor desarrollo de complicaciones y con tasas de mortalidad inferiores al período anterior. La menor edad y la no vacunación previa se consideran factores de riesgo para el desarrollo de complicaciones. La vacunación en mujeres embarazadas probablemente disminuirá la incidencia en el futuro, sobre todo en niños menores de 6 meses.
RESUMO
Infections remain an issue of particular relevance in renal transplant patients, particularly viral infections. Human parvovirus B19 infection causes severe refractory anaemia, pancytopenia and thrombotic microangiopathy. Its presence is recognized by analysing blood polymerase chain reaction (PCR) and by the discovery of typical giant proerythroblasts in the bone marrow. We report the case of a 65 year-old man with a history of deceased donor renal transplant in September 2014. At 38 days after the transplant, the patient presented progressive anaemia that was resistant to erythropoiesis-stimulating agents. At 64 days after transplant, hyperthermia occurred with progressive deterioration of the patient's general condition. The viral serology and the first blood PCR for human parvovirus B19 were both negative. At 4 months and 19 days after, a bone marrow biopsy was conducted, showing giant erythroblasts with nuclear viral inclusions that were compatible with parvovirus; a PCR in the tissue confirmed the diagnosis. A second blood PCR was positive for parvovirus. After treatment with intravenous immunoglobulin and the temporary discontinuation of mycophenolate mofetil, a complete remission of the disease occurred, although the blood PCR for parvovirus B19 remained positive, so monitoring is necessary for future likely recurrence.

Molecular epidemiology allows us to know local HIV transmission and to design strategies of prevention. We studied 25 HIV newly diagnosed patients with the E138A mutation since the year 2010. Most transmission networks involved young and promiscuous men who have sex with men. Recent infection was only documented in patients grouped into the smaller clusters.

OBJECTIVE: To investigate the prevalence of hepatitis B virus (HBV) genotypes in Spanish hepatitis B carriers, and to study the differences in epidemiological characteristics, e antigen (HBeAg) seroconversion, serum DNA viral levels (VL) and liver function alterations. METHODS: This study included 108 patients. Genotyping was carried out in 84 with the INNO-LiPA HBV genotyping assay (Innogenetics). RESULTS: There were 41 women and 67 men, with a mean age of 44.1 years. The source of transmission was family contact in 26 patients (24.1%); transfusions in 10 (9.3%); sexual promiscuity in 9 (8.3%), intravenous drug use in 3 (2.8%), health care accident in 2 (1.8%); and unknown causes in 58 (53.7%). Forty patients had chronic hepatitis and 68 (63%) were healthy carriers. The time of evolution of the infection was known in only in 45 patients, and was over 10 years in 42 of them. One hundred patients (92.6%) were HbeAg-negative and 90 (83.3%) had detectable viral DNA. Genotype A was present in 46 (54.8%), D in 20 (23.8%), F in 2 (2,4%), C in 1 (1.2%), A-G coinfection in 7 (8.3%), A-D in 4 (4.8%), D-G in 2 (2,4%), A-C in 1 (1.2%), and A-D-G in 1 (1.2%). There were no significant differences between genotypes. A trend towards an association was found between VL Assuntos
