Epidemiological characteristics and outcomes of COVID-19 cases: mortality inequalities by socio-economic status, Barcelona, Spain, 24 February to 4 May 2020.

BackgroundPopulation-based studies characterising outcomes of COVID-19 in European settings are limited, and effects of socio-economic status (SES) on outcomes have not been widely investigated. AimWe describe the epidemiological characteristics of COVID-19 cases, highlighting incidence and mortality rate differences across SES during the first wave in Barcelona, Catalonia, Spain.MethodsThis population-based study reports individual-level data of laboratory-confirmed COVID-19 cases diagnosed from 24 February to 4 May 2020, notified to the Public Health Agency of Barcelona and followed until 15 June 2020. We analysed end-of-study vital status and the effects of chronic conditions on mortality using logistic regression. Geocoded addresses were linked to basic health area SES data, estimated using the composed socio-economic index. We estimated age-standardised incidence, hospitalisation, and mortality rates by SES.ResultsOf 15,554 COVID-19-confirmed cases, the majority were women (n = 9,028; 58%), median age was 63 years (interquartile range: 46-83), 8,046 (54%) required hospitalisation, and 2,287 (15%) cases died. Prevalence of chronic conditions varied across SES, and multiple chronic conditions increased risk of death (≥ 3, adjusted odds ratio: 2.3). Age-standardised rates (incidence, hospitalisation, mortality) were highest in the most deprived SES quartile (incidence: 1,011 (95% confidence interval (CI): 975-1,047); hospitalisation: 619 (95% CI: 591-648); mortality: 150 (95% CI: 136-165)) and lowest in the most affluent (incidence: 784 (95% CI: 759-809); hospitalisation: 400 (95% CI: 382-418); mortality: 121 (95% CI: 112-131)).ConclusionsCOVID-19 outcomes varied markedly across SES, underscoring the need to implement effective preventive strategies for vulnerable populations.

Epidemiology of infections by HIV, Syphilis, Gonorrhea and Lymphogranuloma Venereum in Barcelona City: a population-based incidence study.

BACKGROUND: The aim of this study was to determine the evolution of HIV infection, gonorrhea, syphilis and lymphogranuloma venereum (LGV), and their epidemiological characteristics in Barcelona city. METHODS: Population-based incidence study of all newly occurring diagnoses of HIV infection, syphilis, gonorrhea and LGV detected in Barcelona between January 2007 and December 2011. A descriptive analysis was performed. The annual incidence rates per 100,000 inhabitants were calculated by sex, sexual conduct and educational level. To estimate global sex-specific rates we used the Barcelona city census; for the calculation of rates by sexual conduct and educational level we used estimates of the Barcelona Health Interview Survey. Trends were analysed using the chi-squared test for linear trend. RESULTS: HIV. 66.8 % of the HIV cases were men who had sex with men (MSM). The incidence rates in MSM over the study period were from 692.67/100,000 to 909.88/100,000 inh. Syphilis. 74.2 % of the syphilis cases were MSM. The incidence rates in MSM were from 224.9/100,000 to 891.97/100,000 inh. and the MSM with a university education ranged from 196.3/100,000 to 1020.8/100,000. Gonorrhea. 45.5 % of the gonorrhea cases were MSM. The incidence rates in MSM were from 164.24/100,000 to 404.79/100,000 inh. and the MSM with university education ranged from 176.7/100,000 to 530.1/100,000 inh.. Lymphogranuloma venereum (LGV). 95.3 % of the LGV cases are MSM. The incidence rates in MSM were from 24.99/100,000 to 282.99/100,000 inh. and the MSM with university education ranged from 9.3/100,000 to 265/100,000 inh. CONCLUSION: An increase in cases of STI was observed. These STI mainly affected MSM with a university education. Continuing to monitor changes in the epidemiology of STI, and identifying the most affected groups should permit redesigning preventive programs, with the goal of finding the most efficient way to reach these population groups.

Effectiveness of ritonavir-boosted protease inhibitor monotherapy in the clinical setting: same results as in clinical trials? The PIMOCS Study Group.

OBJECTIVES: Ritonavir-boosted protease inhibitor monotherapy (PIMT) is a maintenance strategy that prevents nucleoside reverse transcriptase inhibitor toxicity and reduces costs. Some trials compare PIMT with combined antiretroviral therapy, but restricted selection criteria and low sample size hamper data extrapolation to routine practice. Here, we analyse the effectiveness and safety of PIMT in clinical practice. METHODS: This was a retrospective, observational, multicentre study. Adult HIV-1 patients receiving PIMT with darunavir or lopinavir were included. A Cox regression model identified independent predictors for virological failure (VF). RESULTS: A total of 664 patients (435 on darunavir/ritonavir and 229 on lopinavir/ritonavir) [74% male, median age of 54 years, one-third with previous protease inhibitor VF, CD4 nadir 189 cells/mm(3) and 42% coinfected with hepatitis C virus (HCV)] were analysed. After a median follow-up of 16 months, 78% of patients (95% CI 74%-81%) remained free from therapeutic failure (TF) (change between ritonavir-boosted PIs not considered failure). At 12 months, by intention-to-treat analysis (change between ritonavir-boosted PIs equals failure), 83% of patients were free from TF (87% darunavir/ritonavir versus 77% lopinavir/ritonavir, P = 0.001). Regarding VF, 88% of patients maintained viral suppression at 12 months (93% darunavir/ritonavir versus 88% lopinavir/ritonavir, P = not significant). CD4 nadir <200 cells/mm(3) [hazard ratio (HR) 1.58, 95% CI 1.01-2.49] and undetectable viral load prior to PIMT <24 months (HR 1.86, 95% CI 1.20-2.91) were independent predictors for VF. Prior protease inhibitor failure, HCV coinfection and the protease inhibitor/ritonavir used were not associated with PIMT outcome. A total of 158 patients stopped PIMT, 6% due to adverse events. Two patients developed encephalitis. CONCLUSIONS: PIMT effectiveness was consistent with data from clinical trials. Viral suppression duration prior to PIMT and CD4 cell count nadir were independent predictors for PIMT outcome.

The COVID-19 epidemic represents a special risk for kidney patients due to their comorbidities and advanced age, and the need for hemodialysis treatment in group rooms. It also represents a risk for professionals responsible for their attention. This manuscript contains a proposal for action to prevent infection of professionals in the Nephrology Services, one of the most valuable assets at the present time.

[Management of the SARS-CoV-2 (COVID-19) coronavirus epidemic in hemodialysis units]. / Manejo de la epidemia por coronavirus SARS-CoV-2 (COVID-19) en unidades de hemodiálisis.

The current outbreak of SARS-CoV-2 represents a special risk for renal patients due to their comorbidities and advanced age. The usual performance of hemodialysis treatments in collective rooms increases the risk. The specific information at this time in this regard is very limited. This manuscript includes a proposal for action to prevent infection in the Nephrology Services, and in particular in Hemodialysis Units, with the objective of early identification of patients who meet the definition of a suspected case of infection by SARS-CoV-2 and propose circuits and mechanisms to carry out hemodialysis treatments. They are recommendations in continuous review and can be modified if the epidemiological situation, the diagnostic and therapeutic options so require.
