OBJECTIVES: During the last decade, some changes in the epidemiology of invasive infections have been reported; however, specific studies with patient-level data are scarce. The aim of this study was to describe and evaluate the epidemiologic changes in bloodstream infections (BSI) during the last decade in Andalucía, Spain. METHODS: Data from two prospective cohorts of BSI in adults with the same methodology performed 10 years apart in 11 hospitals (eight tertiary and three community) in Andalucía, Spain, were compared; the 2006-7 cohort study was performed between October 2006 and March 2007, and the 2016-17 cohort study was performed between October 2016 and March 2017. Population-based incidence rates were calculated and extrapolated for 1 year. Relative risk ratios were calculated between the 2 periods. Multivariate analyses were performed by logistic regression. RESULTS: Overall, 1262 episodes of BSI were included, 563 (44.6%) in 2006-7 and 699 (55.3%) in 2016-17. Multivariate models selected the following changes in patients' features in 2016-17, after controlling for type of acquisition: higher age (odds ratio (OR) = 1.02; 95% confidence interval [CI] 1.01-1.03), lower urinary catheter (OR = 0.37; 95% CI, 0.26-0.48) and lower Pitt score (OR = 0.76; 95% CI, 0.71-0.82). Adjusted estimations considering patients' features and exposure to procedures showed a reduction in coagulase-negative staphylococci (OR = 0.47; 95% CI, 0.32-0.69), and an increase in Proteus spp. (OR = 3.12; 95% CI, 1.18-8.23) and Candida spp. (OR = 3.01; 95% CI, 1.03-8.86). CONCLUSIONS: We found relevant epidemiologic changes in BSI in our area, including rates, frequency of acquisition types, changes in patient's profiles and aetiologic agents.

Our aim was to evaluate the killer cell immunoglobulin-like receptors (KIRs) as a marker for the development of thrombocytopenia secondary to Peg-interferon (IFN) therapy in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infected patients. Patients were naive to HCV treatment, receiving a first course of Peg-IFN/Ribavirin combination therapy. Total platelet count (cells ml-1) was determined at each visit, determining platelet decline from baseline to weeks 1, 2, 4, 8 and 12 after starting therapy. The end point of the study was development of thrombocytopenia, defined as a platelet count of <1 50 000 cells ml-1. Fifty-eight HIV/HCV co-infected patients were included in the study, of whom 20 (34.4%) developed thrombocytopenia. The absence of KIR2DS2 was associated with higher and faster rate of thrombocytopenia (54.2% vs 22.5%; P=0.012; 6.6 vs 10.3 weeks; P=0.008). The absence of KIR2DS2 was associated with a greater decline in platelet count and development of thrombocytopenia during Peg-IFN treatment in HIV/HCV co-infected patients.

We analysed the efficacy and safety of switching from a regimen based on nonnucleoside reverse transcriptase inhibitors (NNRTI) or integrase inhibitors (INI) to ABC/3TC + RPV in virologically suppressed HIV-infected patients. This multicentre, retrospective study comprised asymptomatic HIV-infected patients who switched from 2 NRTI + NNRTI or 2 NRTI + INI to ABC/3TC + RPV between February 2013 and December 2013; all had undetectable HIV viral load prior to switching. Efficacy and safety, and changes in lipids and cardiovascular risk (CVR) were analysed at 48 weeks. Of 85 patients (74.1 % men, mean age 49.5 years), 83 (97.6 %) switched from a regimen based on NNRTI (EFV 74, RPV 5, ETV 2, NVP 2), and 45 (53 %) switched from TDF/FTC to ABC/3TC. The main reasons for switching were toxicity (58.8 %) and convenience (29.4 %). At 48 weeks, 78 (91.8 %) patients continued taking the same regimen; efficacy was 88 % by intention to treat, and 96 % by per protocol. Two patients were lost to follow-up and five ceased the new regimen (4 due to adverse effects and 1 virologic failure). Mean CD4 cell counts increased (744 vs. 885 cells/µL; p = 0.0001), and there were mean decreases in fasting total cholesterol (-15.9 mg/dL; p < 0.0001) and LDL-cholesterol (-11.0 mg/dL; p < 0.004), with no changes in HDL-cholesterol, triglycerides, total cholesterol:HDL-cholesterol ratio, and CVR. ABC/3TC + RPV is effective and safe in virologically-suppressed patients on antiretroviral therapy (ART). Forty-eight weeks after switching the lipid profile improved with decreases in total and LDL cholesterol.

PURPOSE: Hepatitis C virus (HCV) viral relapse (VR) after end-of-treatment response (ETR) in human immunodeficiency virus (HIV) co-infected patients is observed in as many as one in three co-infected patients. The aim of the study was to identify baseline risk factors for VR in HIV/HCV co-infected patients treated with pegylated interferon plus ribavirin (PEG-INF/RBV). METHODS: A total of 212 Caucasian HIV-infected patients with chronic hepatitis C naïve for PEG-INF/RBV were followed prospectively. Patients were included in this prospective study if they had completed a full course of therapy with an ETR. We assessed the relationship between VR rate and potential predictors of relapse. RESULTS: Of the patients followed, 130 (61.3 %) attained ETR and 103 (79.2 %) achieved sustained virological response (SVR). Consequently, 27 (20.8 %) showed VR. Patients who relapsed were more often male (p = 0.036), carried the non-CC rs14158 genotype in the low-density lipoprotein receptor (LDLr) gene (p = 0.039), had higher baseline HCV RNA levels (p = 0.012), body mass index (BMI) ≥ 25 kg/m(2) (p = 0.034), significant liver fibrosis (p < 0.001), had been diagnosed with acquired immunodeficiency syndrome (AIDS)-defining criteria in the past (p = 0.001) and bore the HCV genotypes 1/4 (p = 0.046) when compared with SVR patients. The IL28B genotype was not associated with relapse. Multivariate binary logistic regression showed that high baseline HCV RNA, significant liver fibrosis, HCV genotypes 1/4, being overweight and being diagnosed with AIDS-defining criteria in the past were independently associated with relapse. CONCLUSIONS: Our study shows that VR can be accurately predicted in HIV/HCV co-infected patients on the basis of risk factors which can be identified before treatment.

BACKGROUND: The factors that influence liver fibrosis progression in patients co-infected with human immunodeficiency virus/hepatitis C virus (HIV/HCV) are not completely understood. It is not known if insulin resistance (IR), a condition that promotes liver fibrosis in HCV mono-infected individuals, is one of these factors. OBJECTIVE: To evaluate the association between IR and liver stiffness (LS). DESIGN: Multicentre cross-sectional study. PATIENTS: 330 patients co-infected with HIV/HCV. METHODS: LS was assessed by transient elastography, which has shown a high accuracy to predict significant fibrosis in patients co-infected with HIV/HCV. The outcome variable of the study was LS. Patients with LS> or =9 kPa were considered as having significant fibrosis. IR was calculated using the HOMA method. RESULTS: LS was > or =9 kPa in 150 (45%) patients. HOMA correlated with LS (Spearman's rho correlation coefficient, 0.37; p<0.0001). The median (Q1-Q3) HOMA in patients with LS> or =9 kPa was 3.30 (2.17-5.16) while it was 2.09 (1.37-3.22) in patients with LS <9 kPa (p<0.0001). Ninety-six (39%) individuals with a HOMA <4 and 54 (63%) with a HOMA > or =4 showed LS> or =9 kPa (p<0.0001). Analyses after excluding patients with cirrhosis yielded similar results. After multivariate analyses, age > or =40 years (adjusted odds ratio (AOR), 1.85; 95% confidence interval (CI), 1.03 to 3.29; p = 0.03), CD4 cell count <200 cells/ml (AOR, 3.45; 95% CI, 1.67 to 7.11; p = 0.001), hepatitis B virus co-infection (AOR, 9.25; 95% CI, 2.42 to 35.31; p = 0.001), and HOMA > or =4 (AOR, 5.33; 95% CI, 2.70 to 10.49; p<0.0001) were the independent predictors of LS> or =9 kPa. CONCLUSION: IR is associated with LS in patients co-infected with HIV/HCV.

INTRODUCTION: Sotos syndrome is a form of infantile gigantism characterized by excessive body size from the time of birth, particular facies, acromegalic changes and signs of non-progressive cerebral involvement. The etiology is unknown. Diagnosis is based on somatometric data and the particular phenotype traits. Biochemical and endocrine studies are normal. Torticollis is a focal dystonia and therefore more common in adults. CLINICAL CASE: A 20 year old woman with macrosomic features since birth presented with: weight 104 kg, height 182 cm; prognathism, hypertelorism, a broad over hanging forehead with a high hair line; large ears, hands and feet; torticollis towards the right with elevation and anteroversion of the right shoulder which caused symptomatic scoliosis. She was bradypsychic and rather slow in speech. The complementary tests done (cerebral and cervical CT and MR, bone gammography, evoked potentials, EMG-ENG, sural nerve biopsy, biopsy of skin and muscle, EEG and hormone and biochemistry studies) were normal. The torticollis was treated with botulinus toxin and improved considerably, as did the scoliosis. CONCLUSIONS: To date, dystonia has not been described in association with Sotos syndrome. This may be a causal association, or even perhaps hereditary, since the patient's mother had dystonia (in the form of blepharospasm).

UNLABELLED: Protein-energy malnutrition (PEM), is probably underestimated in our hospitals. We did this study with the aim of knowing the incidence, distribution and evolution of PEM in a University Hospital with 538 beds. MATERIAL AND METHODS: 301 hospitalized patients, randomly selected, were subjected to a nutritional evaluation upon admittance and after 7 days, by determining albumin and body weigh/ideal weight ratio. RESULTS: The age was 56.7 +/- 18.4 years (x +/- SD), the hospital stay was 7.84 +/- 7.12 days, 194 patients were hospitalized in Medical departments and 107 in Surgical or Medical-surgical departments. The incidence of PEM upon admittance was n = 160 (53%): mild in 93 (30.89%), moderate in 56 (18.60%), and severe in 11 (3.65%). The patients who continued to be hospitalized after 7 days were n = 99 (32.89%), and in these patients the incidence of PEM was n = 66 (66.6%): mild in 33 (33.3%), moderate in 30 (30.3%), and severe in 3 (3.3%). The incidence of PEM was higher at more advanced age (p < 0.05), in patients hospitalized in medical departments (p < 0.05) or in those subjected to surgery (p < 0.05). The hospital stay was longer in those patients who presented PEM upon admittance (p < 0.05). CONCLUSIONS: Malnutrition has an increased incidence in hospitalized patients, it is higher in patients of advanced age or subjected to surgery, and it increases during their stay. The existence of malnutrition upon admittance is related to a longer hospital stay.
