RESUMEN

PURPOSE: Assess the impact of viral load estimated by cycle threshold (Ct) of reverse transcription real time-polymerase chain reaction (rRT-PCR) and the days from symptoms onset on mortality in hospitalized patients with COVID19. METHODS: Retrospective observational study of 782 patients with a positive rRT-PCR from a nasopharyngeal swab was performed within the first 24 h from admission. Demographic data, clinical manifestations and laboratory parameters were collected. Uni- and multivariate analyses were performed to identify factors associated with mortality at 60 days. RESULTS: Ct was divided into three groups and the mortality rate decreased from 27.3 to 20.7% and 9.8% for Ct values of ≤ 20, 21-25 and > 25, respectively (P = 0.0001). The multivariate analysis identified as predictors of mortality, a Ct value < 20 (OR 3.13, CI 95% 1.38-7.10), between 21-25 (OR 2.47, CI 95% 1.32-4.64) with respect to a Ct value > 25. Days from symptoms onset is a variable associated with mortality as well (DSOA) ≤ 6 (OR 1.86, CI 95% 1.00-3.46), among other factors. Patients requiring hospital admission within 6 DSOA with a Ct value ≤ 25 had the highest mortality rate (28%). CONCLUSIONS: The inclusion of Ct values and DSOA in the characterization of study populations could be a useful tool to evaluate the efficacy of antivirals.

RESUMEN

BACKGROUND: A hepatitis C (HCV) cure is associated with changes in lipids and inflammatory biomarkers, but its impact on clinical endpoints among treated human immunodeficiency virus (HIV)/HCV coinfected persons is unclear. METHODS: People living with HIV from EuroSIDA with a known HCV status after January 2001 were classified into strata based on time-updated HCV RNA measurements and HCV treatment, as either HCV antibody-negative; spontaneously resolved HCV; chronic, untreated HCV; cured HCV (HCV RNA-negative); or HCV treatment failures (HCV RNA-positive). Poisson regression was used to compare incidence rates between HCV groups for end-stage liver disease (ESLD; including hepatocellular carcinoma [HCC]), non-acquired immunodeficiency virus defining malignancy (NADM; excluding HCC), and cardiovascular disease (CVD). RESULTS: There were 16 618 persons included (median follow-up 8.3 years, interquartile range 3.1-13.7). There were 887 CVD, 902 NADM, and 436 ESLD events; crude incidence rates/1000 person-years follow-up were 6.4 (95% confidence interval [CI] 6.0-6.9) for CVD, 6.5 (95% CI 6.1-6.9) for NADM, and 3.1 (95% CI 2.8-3.4) for ESLD. After adjustment, there were no differences in incidence rates of NADM or CVD across the 5 groups. HCV-negative individuals (adjusted incidence rate ratio [aIRR] 0.22, 95% CI 0.14-0.34) and those with spontaneous clearance (aIRR 0.61, 95% CI 0.36-1.02) had reduced rates of ESLD compared to cured individuals. Persons with chronic, untreated HCV infections (aIRR 1.47, 95% CI 1.02-2.13) or treatment failure (aIRR 1.80, 95% CI 1.22-2.66) had significantly raised rates of ESLD, compared to those who were cured. CONCLUSIONS: Incidences of NADM or CVD were independent of HCV group, whereas those cured had substantially lower incidences of ESLD, underlining the importance of successful HCV treatment for reducing ESLD.

RESUMEN

IMPORTANCE: Identifying undetected clinical signs is imperative in the prevention of SARS-CoV-2. OBJECTIVE: To establish the prevalence of clinical gustatory and olfactory dysfunctions in patients with COVID-19 pneumonia. Clinical outcomes and recovery rates associated with gustatory and olfactory dysfunctions were also assessed. DESIGN: A prospective study was performed in 80 patients admitted to Hospital Clínic of Barcelona (Spain) for COVID-19 pneumonia. Patients were re-evaluated in the ward daily until discharge. Gustatory and olfactory dysfunction symptoms were retrospectively collected from emergency room (ER) charts after first assessments. Follow-up was performed in telemedicine consultation. SETTING: The single-centre study was performed in a hospitalisation ward at a university hospital. PARTICIPANTS: Consecutive patients meeting hospitalisation criteria for COVID-19 pneumonia were eligible. Study exclusion criteria were patients who could not speak, had previous gustatory and olfactory dysfunctions or whose PCR tests for SARS-CoV-19 were negative. INTERVENTIONS: Systematic assessment of gustatory and olfactory symptoms with standardised questions. OUTCOMES: Prevalence of gustatory and olfactory dysfunctions in patients with COVID-19 pneumonia. RESULTS: Of the 80 study subjects, 62.5% were male and the median age was 57 years. Half of the cohort (n=40) presented with comorbidities. The prevalence of chemosensitive disorder was 73.8% (n=59) (95% CI: 63.8 to 83.8), although self-reported symptoms were recorded in only 26.3% (n=21) of patients in the ER. Gustatory and olfactory dysfunctions were observed in 58.8% (n=47) and 55% (n=44) of cases, respectively. They were also the first symptoms in 25% (n=20) of patients. Anosmia was associated with ageusia, OR: 7, 95% CI: 2.3 to 21.8, p=0.001). No differences in clinical outcomes were observed when patients with and without gustatory and olfactory dysfunctions were compared. Recovery rates were 20% (n=10) and 85% (n=42) at days 7 and 45, respectively. CONCLUSION: The prevalence of gustatory and olfactory dysfunctions in COVID-19 pneumonia was much higher than in self-report. Presence of gustatory and olfactory dysfunctions was not a predictor of clinical outcomes.

RESUMEN

BACKGROUND: Hepatitis C virus (HCV) infection has been associated with increased risk of chronic kidney disease (CKD). We investigated the impact of HCV cure on CKD in HIV-positive persons in the EuroSIDA study. METHODS: HIV-positive persons with known HCV status and at least three serum creatinine measurements after 1/1/2004 were compared based on time-updated HCV-RNA and HCV treatment: anti-HCV-negative, spontaneously cleared HCV, chronic untreated HCV, successfully treated HCV, and HCV-RNA positive after HCV treatment. Poisson regression compared incidence rates of CKD [confirmed (>3 months apart) eGFR <60 ml/min per 1.73 m] between HCV strata. RESULTS: Fourteen thousand, seven hundred and fifty-four persons were included; at baseline 9273 (62.9%) were HCV-Ab negative, 696 (4.7%) spontaneous clearers, 3021 (20.5%) chronically infected, 922 (6.2%) successfully treated and 842 (5.7%) HCV-RNA positive after treatment. During 115 335 person-years of follow-up (PYFU), 1128 (7.6%) developed CKD; crude incidence 9.8/1000 PYFU (95% CI 9.2-10.4). After adjustment, persons anti-HCV negative [adjusted incidence rate ratio (aIRR) 0.59; 95% CI 0.46-0.75] and spontaneous clearers (aIRR 0.67; 95% CI 0.47-0.97) had significantly lower rates of CKD compared with those cured whereas persons chronically infected (aIRR 0.85; 95% CI 0.65-1.12) and HCV-RNA positive after treatment (aIRR 0.71; 95% CI 0.49-1.04) had similar rates. Analysis in those without F3/F4 liver fibrosis using a more rigorous definition of CKD showed similar results. CONCLUSION: This large study found no evidence that successful HCV treatment reduced CKD incidence. Confounding by indication, where those with highest risk of CKD were prioritized for HCV treatment in the DAA era, may contribute to these findings.

RESUMEN

BACKGROUND: The incidence of acute hepatitis C (AHC) among HIV-infected men who have sex with men (MSM) has increased significantly in the last 10 years. Several studies point to a social and sexual network of HIV-positive MSM that extends internationally. OBJECTIVES: The aim of our study was to investigate the dynamics of HCV transmission in an outbreak of AHC in HIV-infected MSM in Barcelona by ultra-deep pyrosequencing. STUDY DESIGN: Between 2008 and 2013, 113 cases of AHC in HIV-infected MSM were diagnosed in the Infectious Diseases Unit, Hospital Clínic, Barcelona. Massive sequencing was performed using the Roche 454 GS Junior platform. To define possible transmission networks, maximum likelihood phylogenetic trees were constructed, and levels of genetic diversity within and among patients were compared. RESULTS: Among the 70 cases analyzed, we have identified 16 potential clusters of transmission: 8 for genotype 1a (23 cases involved), 1 for genotype 1b (3 cases) and 7 for genotype 4d (27 cases). Although the initial phylogenetic reconstruction suggested a local transmission cluster of HCV gt4d, our approach based on low genetic differentiation did not corroborate it. Indeed, gt4d strains formed 4 independent groups related to patients from other countries. CONCLUSIONS: Frequent clustering of HIV-positive MSM shows that HCV infection has spread through a local network in Barcelona. This outbreak is related to a large international HCV transmission network among MSM. Public health efforts are needed to reduce HCV transmission among this high-risk group.

RESUMEN

BACKGROUND: Coinfection with hepatitis C virus (HCV) and HIV is not uncommon and therapies for both infections are currently available. A major drawback, however, could be a potentially higher risk for mitochondrial toxicity (MT), defined as the elevation of pancreatic enzymes or lactate levels due to the nucleoside analogue reverse transcriptase inhibitors contained in both therapies. METHODS: Prospective analyses of clinical and laboratory data, including plasma lactate levels and pancreatic enzymes, of 113 consecutive HIV/HCV-coinfected patients were assigned to receive ribavirin (RBV) plus interferon (IFN)-alpha. RESULTS: Fourteen patients (12%) showed increased levels of amylase/lipase and/or hyperlactataemia. No patient developed clinical pancreatitis. Four patients with hyperlactataemia had clinical symptoms of lactic acidosis and recovered uneventfully by 2 weeks after treatment withdrawal. The variables significantly associated with MT in the univariate analysis were: therapy with didanosine (ddl), ddl plus stavudine (d4T), previous history of diabetes and the baseline lactate level. However, ddl use was the only independent risk factor for MT identified in the multivariate analysis. MT was not associated with gender, age, alcohol consumption, type of IFN, degree of steatosis and fibrosis in liver biopsy, presence of lipodystrophy, CD4+ cell count, HCV or HIV viral load, mitochondrial DNA and COXII-expression in liver tissue, or antiretroviral therapy containing d4T or protease inhibitors. CONCLUSIONS: 12% of HIV/HCV-coinfected patients receiving IFN plus RBV concomitantly with highly active antiretroviral therapy developed laboratory markers of MT. Although most of cases were asymptomatic, our study suggests that concomitant use of RBV plus ddl should be avoided, and that routine monitoring of lactate and pancreatic enzymes may be recommended.

RESUMEN

A study was performed in 10 European health care centers in which 914 patients coinfected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) who had elevated serum alanine aminotransferase (ALT) levels underwent liver biopsy during the period of 1992 through 2002. Overall, the METAVIR liver fibrosis stage was F0 in 10% of patients, F1 in 33%, F2 in 22%, F3 in 22%, and F4 in 13%. Predictors of severe liver fibrosis (METAVIR stage, F3 or F4) in multivariate analysis were age of >35 years (odds ratio [OR], 2.95; 95% confidence interval [CI], 2.08-4.18), alcohol consumption of >50 g/day (OR, 1.61; 95% CI, 1.1-2.35), and CD4+ T cell count of <500 cells/mm3 (OR, 1.43; 95% CI, 1.03-1.98). Forty-six percent of patients aged >40 years had severe liver fibrosis, compared with 15% of subjects aged <30 years. The use of antiretroviral therapy was not associated with the severity of liver fibrosis. In summary, severe liver fibrosis is frequently found in HCV-HIV-coinfected patients with elevated serum ALT levels, and its severity increases significantly with age. The rate of complications due to end-stage liver disease will inevitably increase in this population, for whom anti-HCV therapy should be considered a priority.

RESUMEN

The chronic infection by the hepatits C virus represents a serious sanitary problem affecting 1-3% of the world-wide population. It is transmitted by sexual route, vertical route and mainly after blood exposure by percutanea route. While HIV shares similar routes of transmission, the co-infection HCV-HIV is very frequent and the chronic hepatopathy and complications associated with its clinical course are an important cause of morbi-mortality in this population. The gold standard of the treatment for the HCV, has been the interferon and later the combination therapy of interferon plus ribavirine. Currently, the combination of ribavirine and a new pegilated formulation of the interferon has become the standard in the treatment reaching rates of sustained viral response around 40-80%.

RESUMEN

The "D drug" HIV reverse-transcriptase inhibitors zalcitabine, didanosine, and stavudine are relatively strong inhibitors of polymerase-gamma compared with the "non-D drugs" zidovudine, lamivudine, and abacavir. D drugs deplete mitochondrial DNA (mtDNA) in cultured hepatocytes. This mtDNA depletion is associated with an increased in vitro production of lactate. To investigate the origin of hyperlactatemia in HIV-infected patients and the effects of antiretroviral therapy on liver mtDNA, we biopsied liver tissue from 94 individuals with chronic hepatitis C virus (HCV) infection. Eighty subjects were coinfected with HIV. Serum lactate was measured at the time of biopsy. Hepatic mtDNA and liver histology were centrally assessed. Liver mtDNA content of HIV-infected patients receiving D drugs at the time of biopsy (n = 34) was decreased by 47% (P<.0001) compared with those without D drugs (n = 35). Aside from a possible association between HCV genotype I status and mtDNA depletion in multivariate analysis, there were no other virologic, immunologic, histologic, demographic or treatment-related variables that could explain the mtDNA depletion. Lactate was above the upper limit of normal in only three patients, all of whom were treated with D drugs. The mtDNA in each of them was lower than in any non-D drug patient and significantly (P =.017) depleted compared with D drug patients with normal lactate. In conclusion, D drug treatment is associated with decreased hepatic mtDNA in HIV-infected patients with chronic HCV infection. Moderate mtDNA depletion in liver does not necessarily lead to hyperlactatemia, but more pronounced decreases in hepatic mtDNA may be an important contributor to lactate elevation.

RESUMEN

According to current estimates, there are 60,000 to 80,000 HIV and HCV coinfected individuals in Spain, and 5,000 to 10,000 HIV and HBV coinfected individuals. Among these patients, 10% to 15% have liver cirrhosis. Thus, end-stage liver disease is one of the major causes of death in our country. Liver transplantation is the only therapeutic option for these patients. Accumulated experience in North America and Europe in the last five years indicates that three-year survival in HIV-positive liver transplant recipients is similar to that of HIV-negative recipients. The selection criteria for HIV transplant candidates includes the following: no history of opportunistic infections, CD4 lymphocyte count higher than 100 cells/mm3, and HIV viral load suppressible with antiretroviral treatment. In Spain, where the majority of patients are former drug abusers, complete abstinence from heroin or cocaine use during two years is also required, with the possibility of the patient being in a methadone program. To date 26 hepatic transplants have been performed in the same number of patients, with only two deaths (7%) after a median follow-up of eight months (1-28). The main problems in the post-transplantation period in all the series has been recurrent HCV infection, which is the principle cause of post-transplantation mortality, and pharmacokinetic and pharmacodynamic interactions between the antiretroviral and immunosuppressive agents. There is little experience with pegylated interferon and ribavirin treatment in this population.
