Abstract
BACKGROUND Concomitant use of bedaquiline (Bdq) and delamanid (Dlm) for multi-drug/rifampicin resistant tuberculosis (MDR/RR-TB) has raised concerns about a potentially poor risk-benefit ratio. Yet this combination is an important alternative for patients infected with strains of TB with complex drug resistance profiles or who cannot tolerate other therapies. We assessed safety and treatment outcomes of MDR/RR-TB patients receiving concomitant Bdq and Dlm, along with other second-line anti-TB drugs. METHODS We conducted a multi-centric, prospective observational cohort study across 14 countries among patients receiving concomitant Bdq-Dlm treatment. Patients were recruited between April 2015 and September 2018 and were followed until the end of treatment. All serious adverse events and adverse events of special interest (AESI), leading to a treatment change, or judged significant by a clinician, were systematically monitored and documented. RESULTS Overall, 472 patients received Bdq and Dlm concomitantly. A large majority also received linezolid (89.6%) and clofazimine (84.5%). Nearly all (90.3%) had extensive disease; most (74.2%) had resistance to fluoroquinolones. The most common AESI were peripheral neuropathy (134, 28.4%) and electrolyte depletion (94, 19.9%). Acute kidney injury and myelosuppression were seen in 40 (8.5%) and 24 (5.1%) of patients, respectively. QT prolongation occurred in 7 patients (1.5%). Overall, 78.0% (358/458) had successful treatment outcomes, 8.9% died, and 7.2% experienced treatment failure. CONCLUSIONS Concomitant use of Bdq and Dlm, along with linezolid and clofazimine, is safe and effective for MDR/RR-TB patients with extensive disease. Using these drugs concomitantly is a good therapeutic option for patients with resistance to many anti-TB drugs.

Abstract
OBJECTIVES To determine the burden and impact of cardiovascular risk factors (CRF) in antiphospholipid syndrome (APS) patients. METHODS Analysis of the patients diagnosed with APS identified in the Spanish Hospital Discharge Database between 2016 and 2017. We analysed the admissions due to arterial (ATE) and venous thromboembolic events (VTE) and evaluated the incidence and the attributed risk of each CRF. RESULTS 5424 admissions in patients diagnosed with APS were identified. 64.6% were women and the mean age was 54.6. The mortality rate was 3.1%. Overall, 35.8% of patients had hypertension, 14% were diabetic, 21.7% hypercholesterolaemic, 9.9% obese and 26.7% smokers. Thromboembolic events (67.9% arterial and 32.1% venous) accounted for 11.9% of admissions and 7.1% of deaths. Male sex (OR 1.83, 95% CI 1.41-2.21), cholesterol (OR 1.25, 95% CI 1.01-1.54) and smoking (OR 1.49, 95% CI 1.22-1.81) were independently associated with thromboembolic events. Meanwhile, patients with ATE were older (57 vs. 54.1 years p=0.033), and presented more secondary APS (17.1% vs. 10.6%, p=0.034), hypertension (47.7% vs. 33.5%, p=0.001), diabetes (16.9% vs. 9.6%, p=0.017), cholesterol (34.3% vs. 17.8%, p<0.001) and smoking habit (41.2% vs. 24%, p<0.001) when compared with VTE. Risk factors independently associated with ATE events were male sex (OR=1.61, 95% CI=1.30-2.03), hypertension (OR=1.30, 95% CI=1.03-1.64), cholesterol (OR=1.51, 95% CI=1.18-1.94) and smoking habit (OR=1.84, 95% CI=1.47-2.32), while VTE events were determined by male sex (OR=2.06, 95% CI=1.53-2.77) and obesity (OR=1.61, CI=1.02-2.52). CONCLUSIONS Thromboembolic events in APS were in part determined by a high prevalence of CRF. The identification of distinct profiles may allow us to undertake a more personalised approach to reduce thromboembolic events and to individualise anticoagulant and antiplatelet therapy.

Advanced glycation end-products in morbid obesity and after bariatric surgery: When glycemic memory starts to fail.

Abstract
BACKGROUND AND OBJECTIVE Advanced glycation end-products (AGEs) are a marker of metabolic memory. Their levels increases when oxidative stress, inflammation, or chronic hyperglycemia exists. The role of morbid obesity in AGE levels, and the impact of bariatric surgery on them are unknown. PATIENTS AND METHOD An observational study with three sex- and age-matched cohorts: 52 patients with obesity, 46 patients undergoing bariatric surgery in the last 5 years, and 46 control subjects. AGE were measured using skin autofluorescence (SAF) in the forearm with an AGE Reader™ (DiagnOptics Technologies, Groningen, The Netherlands). Presence of metabolic syndrome was assessed. RESULTS Patients with morbid obesity had higher SAF levels (2.14±0.65AU) than non-obese subjects (1.81±0.22AU; P<.001), which was mainly attributed to obese subjects with metabolic syndrome (2.44±0.67 vs. 1.86±0.51AU; P<.001). After bariatric surgery, SAF continued to be high (2.18±0.40AU), and greater as compared to the non-obese population (P<.001). A multivariate analysis showed that age and presence of metabolic syndrome (but not sex or body mass index) were independently associated to SAF (R2=0.320). CONCLUSION SAF is increased in patients with morbid obesity and metabolic syndrome, mainly because of the existence of type 2 diabetes mellitus. In the first 5 years following bariatric surgery, weight loss and metabolic improvement are not associated with a parallel decrease in subcutaneous AGE levels.

Abstract
BACKGROUND Renal disease is a leading cause of morbidity in HIV-infected adults in the highly active antiretroviral therapy (HAART) era. Cystatin C has been proposed as a more sensitive marker of renal function, but it may be affected by ongoing inflammation. We aimed to study the cystatin C levels in a cohort of HIV-infected pediatric patients at 3 Spanish centers. METHODS This is a multicenter cross-sectional observational study. Renal function was assessed by means of first morning urine protein/creatinine and albumin/creatinine ratios and creatinine-estimated glomerular filtration rates (GFRs), together with the following inflammation markers: cystatin C, reactive C protein, β-2-microglobulin and 25(OH)-vitamin D levels. A control group of healthy children and adolescents was used. RESULTS Eighty-three patients (51 females, median age: 13.3 years; 32 males, median age: 13.6 years) and 44 controls (24 females, median age: 12.2 years; 20 males, median age: 10.9 years) were included. Among the former, mean CD4 cell count was 860/mm, 29(35%) patients had a previous AIDS diagnosis, 73(88%) were on HAART and HIV viremia was undetectable in 61(73%). No differences in cystatin C levels were observed between the 2 groups. In HIV-infected patients, cystatin C levels correlated with GFR (r = -0.27; P = 0.01), age at first HAART (r = -0.21; P = 0.05), and β-2-microglobulin (r = 0.569; P < 0.01). In multivariate analysis, lower GFR (P = 0.014) and higher β-2-microglobulin levels (P = 0.001) remained as independent risk factors for higher cystatin C values. CONCLUSIONS Cystatin C values were associated with GFR and β-2-microglobulin. Cystatin C may be useful as a marker of renal function in HIV-infected pediatric patients, independently of ongoing inflammation or viremia.
