Background. There are few descriptions of the clinical presentation and evolution of consecutive SARS-CoV-2 infections with a long-enough follow up.
Methods. Description of the first consecutive 100 ...patients with microbiologically-proven COVID-19 in a large hospital in Madrid, Spain including a minimum of two-month follow up.
Results. The median age of the patients (52% males) was 61.5 years (IQR=39.5-82.0) and the median BMI was 28.8 kg/m2 (IQR=24.7-33.7). Overall 72% of the patients had one or more co-morbid conditions with a median age-adjusted Charlson index of 2 (IQR=0-5.7). Five patients (5%) were immunosuppressed. The most common symptoms at the time of diagnosis were fever (80.0%), cough (53.0%) and dyspnea (23.0%). The median O2 saturation at the time of first examination was 94% (IQR=90-97). Chest X-ray on admission was compatible with pneumonia in 63% of the cases (bilateral in 42% and unilateral in 21%). Overall, 30% were managed at home and 70% were admitted to the hospital. Thirteen patients were admitted to the ICU with a median of 11 days of stay in the Unit (IQR=6.0-28.0). CALL score of our population ranged from 4 to 13. Overall, 60.0% of patients received antibiotic treatment and 66.0%, empirical antiviral treatment, mainly with lopinavir/ritonavir (65%) or hydroxychloroquine (42%). Mortality, with a minimum of 60 days of follow up, was 23%. The median age of the deceased patients was 85 years (IQR=79-93).
Conclusions. We found a high mortality in the first 100 patients diagnosed with COVID-19 at our institution, associated with advanced age and the presence of serious underlying diseases.
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.

Direct‐acting antivirals (DAAs) for HCV treatment have improved tolerance and efficacy among adults, but experience in vertical transmission is scarce. In our vertically HIV/HCV co‐infected youth ...cohort of 58 patients, DAA achieved excellent rates of cure among naïve and pretreated individuals. Treating vertically infected seems important as 29.6% displayed advanced fibrosis at treatment initiation.
The incidence of stroke in human immunodeficiency virus (HIV)-infected individuals has been well analyzed in recent epidemiological studies. However, little is known about the specific contribution ...of hepatitis C virus (HCV) infection to stroke among HIV-infected individuals. The aims of this study were to analyze trends in the incidence rates of stroke in HIV-infected individuals during the combination antiretroviral (cART) era in Spain and to categorize them by the presence or absence of HCV coinfection. We analyzed hospital discharges with a diagnosis of stroke in Spain according to ICD-9-CM during 1997-2013. The study period was divided into four calendar periods (1997-1999, 2000-2003, 2004-2007, and 2008-2013). Patients were classified according to HCV serology. The number of HIV-infected patients was estimated based on data from the National Centre of Epidemiology. We calculated incidence rates (events per 10,000 patient-years) and in-hospital case fatality rates (CFR). The incidence of hemorrhagic stroke (HS) decreased in HIV-monoinfected patients (15.8 1997-1999 to 6.5 2008-2013; P<0.001) and increased in HIV/HCV-coinfected patients (1.3 1997-1999 to 5.5 2008-2013; P<0.001). The incidence of ischemic stroke (IS) decreased in HIV-monoinfected patients (27.4 1997-1999 to 21.7 2008-2013; P = 0.005) and increased in HIV/HCV-coinfected patients (1.8 1997-1999 to 11.9 2008-2013; P<0.001). The CFR was 3.3 times higher for HS than for IS for the whole study period. The CFR of HS in HIV-monoinfected patients decreased significantly (47.4% 1997-1999 to 30.6% 2008-2013; P = 0.010) but did not change significantly among HIV/HCV-coinfected patients (41.4% 1997-1999 to 44.7% 2008-2013; P = 0.784). The CFR of IS in the whole HIV-infected population decreased significantly (14.6% 1997-1999 to 10.9% 2008-2013; P = 0.034), although no significant differences were found when each group was analyzed separately. In conclusion, after the introduction of cART, HS and IS rates decreased in HIV-monoinfected individuals, but increased steadily in HIV/HCV-coinfected individuals.
The present outbreak of Human Monkeypox (HMPX) that has begun in May 2022 and has spread across all continents in less than two months has qualitative and quantitative characteristics that make it ...different from the pattern of human disease previously caused by this virus. It has spread with enormous ease, affects almost exclusively adults, behaves as a sexually transmitted disease and focuses on very specific groups and transmission conditions. The high incidence in the city of Madrid in males that have sex with males (MSM) has allowed us to observe and report the experience with the first 30 cases diagnosed in our institution. Patients presented with febrile symptoms, genital and paragenital skin lesions reminiscent of smallpox, but less extensive and severe. The disease may also cause proctitis, pharyngitis and perioral lesions. The PCR test for diagnostic confirmation has been shown to be very sensitive and effective, not only in skin lesions but also in blood and other fluids such as pharyngeal, rectal exudates and blood. A very high proportion of patients with HMPX also have other sexually transmitted diseases that must be actively detected in this context. The spontaneous evolution of our patients has been good and hospitalization has been practically unnecessary. Transmission to non-sexual cohabitants and health personnel has been nonexistent and the lesions have disappeared in less than 30 days without leaving sequelae and no need for specific antiviral treatment.
Objectives
Chronic oxidative stress (OS) may play a role in cardiovascular disease in HIV‐infected patients, and increased bilirubin levels may have a beneficial role in counteracting OS. Atazanavir ...(ATV) inhibits UDP‐glucuronosyl‐transferase 1A1 (UGT1A1), thus increasing unconjugated bilirubin levels. We aimed to compare changes in OS markers in patients on ATV/ritonavir (ATV/r)‐ vs. efavirenz (EFV)‐based first‐line antiretroviral therapy (ART).
Methods
A multicentre, prospective cohort study of HIV‐infected patients who started first‐line ART with either ATV/r or EFV was conducted. Lipoprotein‐associated phospholipase A2 (Lp‐PLA2), myeloperoxidase (MPO) and oxidized low‐density lipoprotein (oxLDL) were measured for 145 patients in samples obtained at baseline and after at least 9 months of ART during which the initial regimen was maintained and the patient was virologically suppressed. The change in OS markers was modelled using multiple linear regressions adjusting for baseline values and confounders.
Results
After adjustment for baseline variables, patients on ATV/r had a significantly greater decrease in Lp‐PLA2 estimated difference −16.3; 95% confidence interval (CI) −31.4, −1.25; P = 0.03 and a significantly smaller increase in OxLDL (estimated difference −21.8; 95% CI −38.0, −5.6; P < 0.01) relative to those on EFV, whereas changes in MPO were not significantly different (estimated difference 1.2; 95% CI −14.3, 16.7; P = 0.88). Adjusted changes in bilirubin were significantly greater for the ATV/r group than for the EFV group (estimated difference 1.33 mg/dL; 95% CI 1.03, 1.52 mg/dL; P < 0.01). Changes in bilirubin and changes in OS markers were significantly correlated.
Conclusions
When compared with EFV, ATV/r‐based therapy was associated with lower levels of oxidative stress biomarkers, which was in part attributable to increased bilirubin levels.
This study aimed to analyse the long-term effect of direct-acting antivirals (DAAs) in vertically acquired HIV/HCV-coinfected youths. We performed a multicentre, longitudinal and observational study ...within the Spanish Cohort of HIV-infected children and adolescents and vertically HIV-infected patients transferred to Adult Units (CoRISpe-FARO). We included HIV/HCV-coinfected youths (n = 24) that received DAAs between 2015 and 2017 with successful sustained viral response (SVR) with a subsequent follow-up of at least three years. Long-term evolution in liver disease severity and haematologic markers, lipid and immune profiles after SVR were assessed. Study times were the start date of DAAs treatment (baseline, T0) and 1, 2, 3, 4 and 5 years after SVR (T1, T2, T3, T4 and T5, respectively). We observed global improvements in liver function data that persist over time and a favourable haematologic and immune outcome at the long-term including a constant augment in leucocytes, neutrophils, neutrophils to lymphocytes ratio (NLR) and CD4/CD8 ratio over-time. Regarding the lipid profile, we found a significant increase in total cholesterol T2, total cholesterol/high-density lipoprotein (HDL) ratio at T4, triglycerides at T5, low-density lipoprotein (LDL) over time, and a decrease in HDL in all patients but with marked higher levels in the subgroup receiving anti-HIV Protease Inhibitor (PI)-based regimens. Comparisons of vertically HIV/HCV-coinfected youths after SVR at 3-year follow-up and a control group of vertically HIV-monoinfected youths never infected by HCV showed no significant differences in most variables analysed, suggesting a possible normalization in all parameters.
Display omitted
•DAAs in vertically HIV/HCV-youths implies a long-term reduction in liver damage biomarkers.•Successful DAAs is accompanied by a constant immune profile recovery.•Pro-atherogenic lipid pattern increases with marked higher levels in the group receiving Protease Inhibitor-based ART.•At 3-year follow-up after SVR, there were no differences compared to vertically HIV-monoinfected youths.
Hepatitis C virus (HCV) antiviral therapy might lead to decreased chronic immune activation and endothelial dysfunction associated with cardiovascular risk. The aim was to evaluate the effect of HCV ...eradication on serum markers of inflammation and endothelial dysfunction markers in HIV/HCV co-infected patients.
We carried out a retrospective study of 69 HIV/HCV co-infected patients on interferon (IFN)-α plus ribavirin. In addition, 47 HIV-infected subjects were selected as a control group. A sustained virological response (SVR) was defined as an undetectable HCV viral load up to 24 weeks after the end of treatment. Tumour necrosis factor (TNF) receptor-1 (TNF-R1), soluble E-selectin (sE-selectin), soluble P-selectin (sP-selectin), soluble intercellular adhesion molecule 1 (sICAM-1) and soluble vascular cell adhesion molecule 1 (sVCAM-1) were measured using a multiplex immunoassay kit.
HIV/HCV co-infected patients had higher values of soluble TNF-R1 (sTNF-R1), sE-selectin and sICAM-1 than HIV mono-infected patients (P < 0.05). SVR patients had a decrease in sTNF-R1, sP-selectin, sE-selectin and sICAM-1 during anti-HCV treatment (P < 0.05) and, at the end of treatment, SVR patients had lower values of sTNF-R1, sE-selectin and sVCAM-1 than non-responder patients (P < 0.05), although the values of sTNF-R1, sP-selectin, sE-selectin and sICAM-1 remained higher than in HIV mono-infected patients (P < 0.05). Moreover, we found a significant positive relationship between an increase in sTNF-R1 and increases in sP-selectin, sE-selectin and sICAM-1 during anti-HCV therapy.
Chronic hepatitis C infection induces alterations of markers of inflammation and endothelial dysfunction. Eradication of HCV, following IFN-α and ribavirin therapy, reduces immune activation as well as markers of inflammation and endothelial dysfunction.
Despite high response rates associated to hepatitis C virus (HCV) treatment, no protective immunity is acquired, allowing for reinfection and continued infectiousness. Distinguishing between relapse ...and reinfection is crucial for patient counselling and to choose the most appropriate retreatment. Here, refined phylogenetic analysis using multiple genes served to assess genotype and reinfection for 53 patients for whom the virus was sampled before start of therapy and at time of sustained virological response evaluation at week 12. At baseline, genotypes were determined as HCV1a (41.5%), HCV1b (24.5%), HCV4 (18.9%) and HCV3a (15.1%), while six cases revealed to be discordantly assigned by phylogeny and commercial assays. Overall, 60.4% was co-infected with HIV. The large majority was classified as people who inject drugs (78.6%), often co-infected with HIV. Transmission was sexual in seven cases, of which five in HIV-positive men-who-have-sex-with-men. Overall, relapse was defined for 44 patients, while no conclusion was drawn for four patients. Five patients were reinfected with a different HCV strain, of which three with a different genotype, showing that phylogeny is needed not only to determine the genotype, but also to distinguish between relapse and intra-subtype reinfection. Of note, phylogenies are more reliable when longer fragments of the viral genome are being sequenced.
A successful Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) variant, B.1.1.7, has recently been reported in the UK, causing global alarm. Most likely, the new variant emerged in a ...persistently infected patient, justifying a special focus on these cases. Our aim in this study was to explore certain clinical profiles involving severe immunosuppression that may help explain the prolonged persistence of viable viruses. We present three severely immunosuppressed cases (A, B, and C) with a history of lymphoma and prolonged SARS-CoV-2 shedding (2, 4, and 6 months), two of whom finally died. Whole-genome sequencing of 9 and 10 specimens from Cases A and B revealed extensive within-patient acquisition of diversity, 12 and 28 new single nucleotide polymorphisms, respectively, which suggests ongoing SARS-CoV-2 replication. This diversity was not observed for Case C after analysing 5 sequential nasopharyngeal specimens and one plasma specimen, and was only observed in one bronchoaspirate specimen, although viral viability was still considered based on constant low Ct values throughout the disease and recovery of the virus in cell cultures. The acquired viral diversity in Cases A and B followed different dynamics. For Case A, new single nucleotide polymorphisms were quickly fixed (13–15 days) after emerging as minority variants, while for Case B, higher diversity was observed at a slower emergence: fixation pace (1–2 months). Slower SARS-CoV-2 evolutionary pace was observed for Case A following the administration of hyperimmune plasma. This work adds knowledge on SARS-CoV-2 prolonged shedding in severely immunocompromised patients and demonstrates viral viability, noteworthy acquired intra-patient diversity, and different SARS-CoV-2 evolutionary dynamics in persistent cases.
