Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019.

OBJECTIVES: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. METHODS: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. RESULTS: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). CONCLUSIONS: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population.

Long-term impact of an intervention on rapid antigen detection tests in acute pharyngitis.

OBJECTIVE: This study was aimed at evaluating the appropriateness of use and interpretation of rapid antigen detection testing (RADT) and antibiotic prescribing for acute pharyngitis six years after a multifaceted intervention. DESIGN: Before-and-after audit-based study. LOCATION: Primary care centres in eight autonomous Communities. PARTICIPANTS: General practitioners (GP) who had participated in the HAPPY AUDIT intervention study in 2008 and 2009 were invited to participate in a third audit-based study six years later (2015). METHOD: RADTs were provided to the participating practices and the GPs were requested to consecutively register all adults with acute pharyngitis. A registration form specifically designed for this study was used. RESULTS: A total of 121 GPs out of the 210 who participated in the first two audits agreed to participate in the third audit (57.6%). They registered 3394 episodes of pharyngitis in the three registrations. RADTs were used in 51.7% of all the cases immediately after the intervention, and in 49.4% six years later. Antibiotics were prescribed in 21.3% and 36.1%, respectively (P<.001), mainly when tonsillar exudates were present, and in 5.3% and 19.2% of those with negative RADT results (P<.001). On adjustment for covariables, compared to the antibiotic prescription observed just after the intervention, significantly more antibiotics were prescribed six years later (odds ratio: 2.24, 95% confidence interval: 1.73-2.89). CONCLUSIONS: This study shows that that the long-term impact of a multifaceted intervention, focusing on the use and interpretation of RADT in patients with acute pharyngitis, is reducing.

HIV Coinfection Predicts Failure of Ledipasvir/Sofosbuvir in Treatment-Naïve Noncirrhotic Patients With HCV Genotype 1.

BACKGROUND: The efficacy of licensed direct-acting antiviral (DAA) regimens is assumed to be the same for hepatitis C virus (HCV)-monoinfected patients (HCV-Mono) and HIV/HCV-coinfected patients (HCV-Co). However, the high sustained viral response (SVR) rates of DAA regimens and the small number of HIV-infected patients included in registration trials have made it difficult to identify predictors of treatment failure, including the presence of HIV. METHODS: We compared treatment outcomes for ledipasvir/sofosbuvir (LDV/SOF) against HCV G1 in treatment-naïve HCV-Mono and HCV-Co without cirrhosis in a prospective registry of individuals receiving DAAs for HCV. RESULTS: Up to September 2017, a total of 17 269 patients were registered, and 1358 patients (1055 HCV-Mono/303 HCV-Co) met the inclusion criteria. Significant differences between HCV-Mono and HCV-Co were observed for age, gender, and G1 subtype distribution. Among HCV-Co, 99.0% were receiving antiretroviral therapy. SVR rates for LDV/SOF at 8 weeks did not differ significantly between HCV-Mono and HCV-Co (96.9% vs 94.0%; P = .199). However, the SVR rate for LDV/SOF at 12 weeks was significantly higher for HCV-Mono than HCV-Co (97.2% vs 91.8%; P = .001). A multivariable logistic regression model including age, sex, liver stiffness, G1 subtype, HCV-RNA, HIV, and treatment duration showed the factors associated with treatment failure to be male sex (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.27-4.91; P = .008) and HIV infection (aOR, 2.23; 95% CI, 1.13-4.38; P = .020). CONCLUSIONS: The results of this large prospective study analyzing outcomes for LDV/SOF against HCV G1 in treatment-naïve noncirrhotic patients suggest that HIV infection is a predictor of treatment failure in patients with chronic hepatitis C.

Reinfection by hepatitis C virus following effective all-oral direct-acting antiviral drug therapy in HIV/hepatitis C virus coinfected individuals.

OBJECTIVES: We analysed hepatitis C virus (HCV) reinfection among participants in a prospective registry of HIV/HCV-coinfected patients treated with all-oral direct-acting antiretroviral (DAA)-based therapy in the region of Madrid. DESIGN: An observational cohort study. METHODS: The study period started on the date sustained viral response (SVR) was confirmed. The censoring date was 31 December 2017. SVR was defined as negative HCV-RNA 12 weeks after completion of treatment. Reinfection was defined as a positive HCV-RNA test result after achievement of SVR. RESULTS: Reinfections were detected in 17 of 2359 HIV/HCV-coinfected patients (0.72%) overall, in 12 out of 177 (6.78%) MSM and in five out of 1459 (0.34%) people who inject drugs (PWID). The incidence of reinfection [95% confidence interval (95% CI)] per 100 person-years was 0.48 (0.30-0.77) overall, 5.93 (3.37-10.44) for MSM and 0.21 (0.09-0.52) for PWID. Reinfections were detected a median of 15 weeks (interquartile range 13-26) after SVR. In 10 (58.82%) patients, the reinfection was caused by a different HCV genotype. All 12 MSM with reinfection acknowledged unprotected anal intercourse with several partners, seven used chemsex, six reported fisting and four practiced slamming. A concomitant STI was detected in five patients. Four IDU with reinfection reported injecting drugs following SVR. CONCLUSION: HCV reinfection is a matter of concern in HIV-positive MSM treated with all-oral DAA therapy in the region of Madrid. Our data suggest that prevention strategies and frequent testing with HCV-RNA should be applied following SVR in MSM who engage in high-risk practices.

Human Immunodeficiency Virus/Hepatits C Virus Coinfection in Spain: Elimination Is Feasible, but the Burden of Residual Cirrhosis Will Be Significant.

BACKGROUND: We assessed the prevalence of antibodies against hepatitis C virus (HCV-Abs) and active HCV infection in patients infected with human immunodeficiency virus (HIV) in Spain in 2016 and compared the results with those of similar studies performed in 2002, 2009, and 2015. METHODS: The study was performed in 43 centers during October-November 2016. The sample was estimated for an accuracy of 2% and selected by proportional allocation and simple random sampling. During 2016, criteria for therapy based on direct-acting antiviral agents (DAA) were at least significant liver fibrosis, severe extrahepatic manifestations of HCV, and high risk of HCV transmissibility. RESULTS: The reference population and the sample size were 38904 and 1588 patients, respectively. The prevalence of HCV-Abs in 2002, 2009, 2015, and 2016 was 60.8%, 50.2%, 37.7%, and 34.6%, respectively (P trend <.001, from 2002 to 2015). The prevalence of active HCV in 2002, 2009, 2015, and 2016 was 54.0%, 34.0%, 22.1%, and 11.7%, respectively (P trend <.001). The anti-HCV treatment uptake in 2002, 2009, 2015, and 2016 was 23.0%, 48.0%, 59.3%, and 74.7%, respectively (P trend <.001). In 2016, HCV-related cirrhosis was present in 7.6% of all HIV-infected individuals, 15.0% of patients with active HCV, and 31.5% of patients who cleared HCV after anti-HCV therapy. CONCLUSIONS: Our findings suggest that with universal access to DAA-based therapy and continued efforts in prevention and screening, it will be possible to eliminate active HCV among HIV-infected individuals in Spain in the short term. However, the burden of HCV-related cirrhosis will continue to be significant among HIV-infected individuals.

All-oral direct-acting antiviral therapy against hepatitis C virus (HCV) in human immunodeficiency virus/HCV-coinfected subjects in real-world practice: Madrid coinfection registry findings.

We evaluated treatment outcomes in a prospective registry of human immunodeficiency virus/hepatitis C virus (HCV)-coinfected patients treated with interferon-free direct-acting antiviral agent-based therapy in hospitals from the region of Madrid between November 2014 and August 2016. We assessed sustained viral response at 12 weeks after completion of treatment and used multivariable logistic regression to identify predictors of treatment failure. We evaluated 2,369 patients, of whom 59.5% did not have cirrhosis, 33.9% had compensated cirrhosis, and 6.6% had decompensated cirrhosis. The predominant HCV genotypes were 1a (40.9%), 4 (22.4%), 1b (15.1%), and 3 (15.0%). Treatment regimens included sofosbuvir (SOF)/ledipasvir (61.9%), SOF plus daclatasvir (14.6%), dasabuvir plus ombitasvir/paritaprevir/ritonavir (13.2%), and other regimens (10.3%). Ribavirin was used in 30.6% of patients. Less than 1% of patients discontinued therapy owing to adverse events. The frequency of sustained viral response by intention-to-treat analysis was 92.0% (95% confidence interval, 90.9%-93.1%) overall, 93.8% (92.4%-95.0%) for no cirrhosis, 91.0% (88.8%-92.9%) for compensated cirrhosis, and 80.8% (73.7%-86.6%) for decompensated cirrhosis. The factors associated with treatment failure were male sex (adjusted odds ratio, 1.75; 95% confidence interval, 1.14-2.69), Centers for Diseases Control and Prevention category C (adjusted odds ratio, 1.65; 95% confidence interval, 1.12-2.41), a baseline cluster of differentiation 4-positive (CD4+) T-cell count <200/mm3 (adjusted odds ratio, 2.30; 95% confidence interval, 1.35-3.92), an HCV RNA load ≥800,000 IU/mL (adjusted odds ratio, 1.63; 95% confidence interval, 1.14-2.36), compensated cirrhosis (adjusted odds ratio, 1.35; 95% confidence interval, 0.96-1.89), decompensated cirrhosis (adjusted odds ratio, 2.92; 95% confidence interval, 1.76-4.87), and the use of SOF plus simeprevir, SOF plus ribavirin, and simeprevir plus daclatasvir. CONCLUSION: In this large real-world study, direct-acting antiviral agent-based therapy was safe and highly effective in coinfected patients; predictors of failure included gender, human immunodeficiency virus-related immunosuppression, HCV RNA load, severity of liver disease, and the use of suboptimal direct-acting antiviral agent-based regimens.

Treatment of febrile neutropenia and prophylaxis in hematologic malignancies: a critical review and update.

Febrile neutropenia is one of the most serious complications in patients with haematological malignancies and chemotherapy. A prompt identification of infection and empirical antibiotic therapy can prolong survival. This paper reviews the guidelines about febrile neutropenia in the setting of hematologic malignancies, providing an overview of the definition of fever and neutropenia, and categories of risk assessment, management of infections, and prophylaxis.

Hip fracture in hospitalized medical patients.

BACKGROUND: The aim of the present study is to analyze the incidence of hip fracture as a complication of admissions to internal medicine units in Spain. METHODS: We analyzed the clinical data of 2,134,363 adults who had been admitted to internal medicine wards. The main outcome was a diagnosis of hip fracture during hospitalization.Outcome measures included rates of in-hospital fractures, length of stay and cost. RESULTS: A total of 1127 (0.057%) admittances were coded with an in-hospital hip fracture. In hospital mortality rate was 27.9% vs 9.4%; p < 0.001, and the mean length of stay was significantly longer for patients with a hip fracture (20.7 days vs 9.8 days; p < 0.001). Cost were higher in hip-fracture patients (6927€ per hospitalization vs 3730€ in non fracture patients). Risk factors related to fracture were: increasing age by 10 years increments (OR 2.32 95% CI 2.11-2.56), female gender (OR 1.22 95% CI 1.08-1.37), admission from nursing home (OR 1.65 95% CI 1.27-2.12), dementia (1.55 OR 95% CI1.30-1.84), malnutrition (OR 2.50 95% CI 1.88-3.32), delirium (OR 1.57 95% CI 1.16-2.14), and anemia (OR 1.30 95%CI 1.12-1.49). CONCLUSIONS: In-hospital hip fracture notably increased mortality during hospitalization, doubling the mean length of stay and mean cost of admission. These are reasons enough to stress the importance of designing and applying multidisciplinary plans focused on reducing the incidence of hip fractures in hospitalized patients.

Differences in the use of health resources by Spanish and immigrant HIV-infected patients.

BACKGROUND: HIV-immigrant use of health services and related cost has hardly been analysed. We compared resource utilisation patterns and direct health care costs between Spanish and immigrant HIV-infected patients. METHODS: All HIV-infected adult patients treated during the years 2003-2005 (372 patients) in this hospital were included. We evaluated the number of out-patient, Emergency Room (ER) and Day-care Unit visits, and number and length of admissions. Direct costs were analysed. We compared all variables between immigrant and Spanish patients. RESULTS: Immigrants represented 12% (n=43) of the cohort. There were no differences in the number of out-patient, ER, and day-care hospital visits per patient between both groups. The number of hospital admissions per patient for any cause was higher in immigrant than in Spanish patients, 1.3 (4.4) versus 0.9 (2.7), P=.034. A high proportion of visits, both for the immigrant (45.1%) and Spanish patients (43.0%), took place in services other than Infectious Diseases. Mean unitary cost per patient per admission, out-patient visits and ER visits were similar between groups. Pharmacy costs per year was higher in Spanish patients than in immigrants (7351.8 versus 7153.9 euros [year 2005], P=.012). There were no differences in the total cost per patient per year between both groups. The global distribution of cost was very similar between both groups; almost 75% of the total cost was attributed to pharmacy in both groups. CONCLUSIONS: There are no significant differences in health resource utilisation and associated costs between immigrant and Spanish HIV patients.

Venous thromboembolism in COPD hospitalized patients.

Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for venous thromboembolism (VTE). We analyzed a large Spanish database to determine the incidence of VTE in these patients during hospitalization. A retrospective chart review of cohort of consecutive patients admitted with COPD as the primary reason for discharge in Spain between January 1st 2006 and December 31st 2007 was performed. For each patient, demographic data, risk factors for VTE and the diagnosis of VTE during hospitalization was recorded. We analyzed the clinical data of 313,233 adults with acute exacerbations of COPD admitted to the hospital at any public centre in Spain, in 2006 and 2007. We identify 3,562 new diagnosed VTE events among 270,840 COPD patients hospitalized more than two days (incidence 1.32%). Hospitalized-acquired VTE risk factors were male gender (odds ratio [OR] 1.77; CI95% 1.66-1.90), neoplasic disease (OR 2.93 CI95% 2.69-3.16, systemic arterial disease (OR 1.17 CI95% 1.10-1.36), decubitus ulcer (OR 1.19 CI95% 1.01-1.43), diabetes (OR 0.74 IC95% 0.69-0.81), and atrial fibrillation (OR 0.79 CI95% 0.72-0.87). VTE appears as a major threat to patients admitted for acute exacerbation of COPD, and pharmacologic prophylaxis should be considered in all high risk situations.

Influence of obesity and malnutrition on acute heart failure.

INTRODUCTION AND OBJECTIVES: Obesity is an independent risk factor for the development of heart failure. Several recent studies have found better outcomes of heart failure for obese patients, an observation termed as the "obesity paradox." On the other hand, the negative effect of malnutrition on the evolution of heart failure has also been clearly established. METHODS: Data from the Minimum Basic Data Set were analyzed for all patients discharged from all the departments of internal medicine in hospitals of the Spanish National Health System between the years 2006 and 2008. The information was limited to those patients with a primary or secondary diagnosis of heart failure. Patients with a diagnosis of obesity or malnutrition were identified. The mortality and readmission indexes of obese and malnourished patients were compared against the subpopulation without these diagnoses. RESULTS: A total of 370,983 heart failure admittances were analyzed, with 41,127 (11.1%) diagnosed with obesity and 4105 (1.1%) with malnutrition. In-hospital global mortality reached 12.9% and the risk of readmission was 16.4%. Obese patients had a lower in-hospital mortality risk (odds ratio [OR]: 0.65, 95% confidence interval [95%CI]: 0.62-0.68) and early readmission risk (OR: 0.81, 95%CI: 0.78-0.83) than nonobese patients. Malnourished patients had a much higher risk of dying while in hospital (OR: 1.83 95%CI: 1.69-1.97) or of being readmitted within 30 days after discharge (OR: 1.39, 95%CI: 1.29-1.51), even after adjusting for possible confounding factors. CONCLUSIONS: Obesity in patients admitted for HF substantially reduces in-hospital mortality risk and the possibility of early readmission, whereas malnutrition is associated with important increases in in-hospital mortality and risk of readmission in the 30 days following discharge.

Venous thromboembolism in acutely ill hospitalized medical patients.

BACKGROUND: Acute and chronic illness, immobility, and procedural and pharmacologic interventions may predispose patients in the Internal Medicine Wards to venous thromboembolic disease (VTE). The purpose of this study was to determine the incidence of VTE in these patients. MATERIALS AND METHODS: A retrospective chart review of cohort of consecutive patients admitted to Internal Medicine wards in Spain between January 1st 2005 and December 31st 2007 was performed. For each patient, demographic data, risk factors for VTE and the diagnosis of VTE during hospitalization was recorded. RESULTS: We analyzed 1,567,659 patients, excluding 28,226 patients who had DVT or PE before admission, and 196,555 who were discharged in the first 48 hours. We identify 12,458 new diagnosed VTE events among 1,344,959 patients (incidence 0.93%) hospitalized more than two days. Hospitalized-acquired VTE risk factors were feminine gender (odds ratio [OR] 1.31; CI95% 1.26-1.35), age >70 (OR 1.08 CI95% 1.04-1.13), acute infectious disease (OR 1.27 CI95% 1.17-1.38), acute respiratory disease (OR 1.23 CI95% 1.17-1.28), dementia (OR 1.22 CI95% 1.14-1.31), neoplasic disease (OR 2.29, CI95% 2.19-2.49), and hemiplegia (OR 1.49, CI95% 1.31-1.69). CONCLUSIONS: The number of patients with VTE in an Internal Medicine ward is higher than expected. Several independent risk factors for VTE were identified. Based on the large number of patients who developed a VTE during hospitalization, our data add strength to the argument that VTE prevention should be high on the list of priorities when health care policies are being formed.

Analysis of the mortality of patients admitted to internal medicine wards over the weekend.

The management of patients admitted during weekends may be compromised because the level of staffing in the hospital is often lower then. This study was conducted to assess what independent influence, if any, weekend admission might have on inhospital mortality. The authors analyzed the clinical data of 429,880 adults >14 years of age who were admitted to internal medicine wards in Spain after having presented to the hospitals' emergency departments. Overall mortality and early mortality (occurring in the first 48 hours) were examined, taking into account whether a patient was admitted on a weekend or a weekday, in addition to other parameters. Weekend admissions were associated with a significantly higher inhospital mortality than weekday admissions among patients admitted to an internal medicine service (odds ratio [OR] = 1.1; 95% confidence interval [CI] = 1.14-1.08). Differences in mortality persisted after adjustment for age, sex, and coexisting disorders (OR = 1.071; 95% CI = 1.046-1.097). Analyses of deaths within 2 days after admission showed larger relative differences in mortality between weekend and weekday admissions (OR = 1.28; 95% CI = 1.22-1.33). For patients admitted to an internal medicine service via an acute care visit to the emergency room, admission on weekends is associated with higher mortality than admission during the week.

Advice from a medical expert through the Internet on queries about AIDS and hepatitis: analysis of a pilot experiment.

BACKGROUND: Advice from a medical expert on concerns and queries expressed anonymously through the Internet by patients and later posted on the Web, offers a new type of patient-doctor relationship. The aim of the current study was to perform a descriptive analysis of questions about AIDS and hepatitis made to an infectious disease expert and sent through the Internet to a consumer-oriented Web site in the Spanish language. METHODS AND FINDINGS: Questions were e-mailed and the questions and answers were posted anonymously in the "expert-advice" section of a Web site focused on AIDS and hepatitis. We performed a descriptive study and a temporal analysis of the questions received in the first 12 months after the launch of the site. A total of 899 questions were received from December 2003 to November 2004, with a marked linear growth pattern. Questions originated in Spain in 68% of cases and 32% came from Latin America (the Caribbean, Central America, and South America). Eighty percent of the senders were male. Most of the questions concerned HIV infection (79%) with many fewer on hepatitis (17%). The highest numbers of questions were submitted just after the weekend (37% of questions were made on Mondays and Tuesdays). Risk factors for contracting HIV infection were the most frequent concern (69%), followed by the window period for detection (12.6%), laboratory results (5.9%), symptoms (4.7%), diagnosis (2.7%), and treatment (2.2%). CONCLUSIONS: Our results confirm a great demand for this type of "ask-the-expert" Internet service, at least for AIDS and hepatitis. Factors such as anonymity, free access, and immediate answers have been key factors in its success.
