Impact of Gestational COVID-19 on Neonatal Outcomes: Is Vertical Infection Possible?

BACKGROUND: The vertical transmission of severe acute respiratory coronavirus-2 (SARS-CoV-2) remains highly debated. Here, we evaluated SARS-CoV-2-transmission in newborns with intrauterine conditions. METHODS: This was a prospective, observational and multicentric study involving 13 Spanish hospitals included in the GEStational and NEOnatal-COVID cohort. Pregnant women with microbiologically confirmed SARS-CoV-2 infection during any trimester of pregnancy or delivery and their newborns were included from March to November 2020. Demographic, clinical and microbiological data were also obtained. Viral loads were analyzed in different maternal and newborn biological samples (placenta, breast milk and maternal blood; urine, meconium and newborn blood). RESULTS: A total of 177 newborns exposed to SARS-CoV-2 were included. Newborns were tested by reverse transcriptase-polymerase chain reaction using nasopharyngeal swabs within the first 24-48 hours of life and at 14 days of life. In total 5.1% were considered to have SARS-CoV-2 infection in the neonatal period, with 1.7% considered intrauterine and 3.4% intrapartum or early postnatal transmission cases. There were no differences in the demographic and clinical characteristics of the pregnant women and their newborns' susceptibility to infections in their perinatal history or background. CONCLUSIONS: Intrauterine transmission of SARS-CoV-2 is possible, although rare, with early postnatal transmission occurring more frequently. Most infected newborns remained asymptomatic or had mild symptoms that evolved well during follow-up. We did not find any maternal characteristics predisposing infants to neonatal infection. All infected newborn mothers had acute infection at delivery.Although there was no presence of SARS-CoV2 in cord blood or breast milk samples, SARS-CoV-2 viral load was detected in urine and meconium samples from infected newborns.

SARS-COV-2 Infection in People Living with HIV: Experience from a Tertiary Hospital in Madrid.

Since SAR-COV-2 infection emerged and spread worldwide, little is known about its impact on people living with human immunodeficiency virus (HIV). We performed a single-center retrospective study to describe the potential particularities and risk factors for respiratory failure (RF) in that population. This single-center retrospective study included patients infected with HIV, whose current follow-up is run in this center, above18 years of age, with diagnosis of SARS-CoV-2 infection between March 5, 2020 and April 15, 2021. We collected data regarding HIV immunological and virological status, main epidemiological characteristics, as well as those conditions considered to potentially influence in SARS-CoV-2 evolution; and clinical, microbiological, radiological, respiratory status, and survival concerning coronavirus disease 2019 (COVID-19). We compared all that, for patients with and without RF and performed a logistic regression for suspected risk factors for RF. One hundred seventy-seven HIV patients were diagnosed from COVID-19 (mean age 53.8 years, 81.3% male). At diagnosis, 95.5% were receiving ART and 91.3% had undetectable viral load, with median CD4 count of 569 cells/µL. One hundred thirty-eight patients (78.4%) had symptoms, 44 (25%) developed RF and 53 (31%) developed bilateral pneumonia. The most commonly used treatments were: steroids (26.7%) and hydroxychloroquine (13.1%). When comparing patients with and without RF, we found statistically significant differences for 20 of the analyzed variables such as age (p < .001) and CD4 (p 0.002), and route of HIV transmission by intravenous drug users IVDU (p 0.002) were determined. In multivariate analysis, age [odds ratio (OR) 1.095] and CD4 count less than 350 cells/µL (OR 3.36) emerged as risk factor for RF. People living with HIV whose CD4 count is <350 cells are at higher risk of developing RF when infected by SARS-CoV-2.

Non-HACEK gram negative bacilli endocarditis: Analysis of a national prospective cohort.

BACKGROUND: Infective endocarditis (IE) due to non-HACEK bacilli (Haemophilus species, Actinobacillus, Cardiobacterium, Eikenella, or Kingella) is uncommon and poorly described. The objectives of this study were to describe non-HACEK Gram-Negative Bacilli (GNB) IE cases and compare characteristic of IE produced by Enterobacterales and non-fermenting (NF) GNB. METHODS: From January 2008 to December 2018, 3910 consecutive patients with definitive IE diagnosis, defined with Modified Duke criteria, either clinical or pathological criteria (e.g. demonstration of non-HACEK GNB in valve culture)were prospectively included. RESULTS: A total of 104 IE cases were caused by non-HACEK GNB (2.6%). Compared to IE due to other microorganisms (excluding HACEK GNB), patients with non-HACEK GNB IE presented with higher age (71 years [IQR 62-78] vs 68 years [IQR: 57-77]; p = 0.026), higher proportion of women (52% vs 31.5%, p < 0.001), higher Charlson Index (5 [IQR: 4-8] vs 4 [IQR 3-7], p = 0.003) and higher in-hospital mortality (36.5% vs 27.1%, p = 0.034). Enterobacterales cases were more frequently associated with genitourinary focus (32.8% vs 5.0%, p = 0.001). NFGNB endocarditis more frequently affected right valves (20.0% vs. 6.3%, p = 0.033), had more common healthcare-related acquisition (67.5% vs. 43.7%, p = 0.030) and venous catheter as focus (40.0% vs. 17.2%, p = 0.019). In the multivariant model, factors related with hospital mortality were: age (OR 1.05, 95%CI 1.00-1.09, p = 0.042), prosthetic valve (OR 2.31, 95%CI 0.90-5.88, p = 0.080), and not performing surgery when indicated (OR 3.60, 95%CI 1.17-11.05, p = 0.025).Patients treated with quinolone combination had lower mortality (OR 0.29; 95%CI 0.09-0.96; p = 0.043). CONCLUSION: Non-HACEK GNB IE is a rare infection characterized by affecting elderly patients with high comorbidity, nosocomial acquisition and unfavorable outcome. Age, prosthetic valve and not performing surgery when indicated are associated with mortality.

Infective endocarditis in patients with cardiac implantable electronic devices: a nationwide study.

AIMS: Patients with infective endocarditis (IE) frequently have cardiac implantable electronic devices (CIEDs). Here, we aim to define the clinical profile and prognostic factors of IE in these patients. METHODS AND RESULTS: Infective endocarditis cases were prospectively identified in the Spanish National Endocarditis Registry. From 3996 IE, 708 (17.7%) had a CIED and 424 CIED-related IE (lead vegetation). Patients with a CIED were older (68 ± 11 vs. 73 ± 8 years); had more comorbidities {pulmonary disease [176 (24.8%) vs. 545 (16.7%)], renal disease [239 (33.8%) vs. 740 (22.7%)], diabetes [248 (35.0%) vs. 867 (26.6%)], and heart failure [348 (49.2%) vs. 978 (29.9%)]}; and fewer complications {intracardiac destruction [106 (15%) vs. 1077 (33.1%)], heart failure [215 (30.3%) vs. 1340 (41.1%)], embolism [107 (15.1%) vs. 714 (21.9%)], and neurological involvement [77 (10.8%) vs. 702 (21.5%)]} (all P-values <0.001) in comparison to subjects without a CIED. In-hospital mortality was similar in patients with and without CIED [171 (24.2%) vs. 881 (27.0%), P = 0.82]. In subjects with a CIED, CIED-related IE was independently associated with in-hospital survival: odds ratio (OR) 0.4 [95% confidence interval (CI) 0.3-0.7, P = 0.001]. Surgery was independently associated with in-hospital survival in CIED-related IE: OR 0.4 (95% CI 0.2-0.7, P = 0.004); but not in subjects with valve IE and no CIED lead involvement: OR 0.9 (95% CI 0.5-1.7, P = 0.77). CONCLUSION: Over a sixth of IE patients have a CIED. This group of patients is older, with more comorbidities and fewer IE-related complications in comparison to subjects without a CIED. In-hospital mortality was similar in patients with and without a CIED.

Etiología de la insuficiencia renal en pacientes con endocarditis infecciosa. Papel de los antibióticos / Aetiology of renal failure in patients with infective endocarditis. The role of antibiotics

Fundamento y objetivos: La toxicidad renal de ciertos antibióticos (AB) es conocida. El objetivo de nuestro trabajo es conocer el posible efecto de los tratamientos AB en el desarrollo de insuficiencia renal (IR) en pacientes con endocarditis infecciosa (EI). Material y método: Recogida en un registro nacional multicéntrico de los datos referentes a la función renal, tanto previa como su deterioro si existiese, durante el tratamiento de las EI y relacionarlo con los posibles factores causantes, entre ellos los AB. Resultados: Entre 2008 y 2012 se han analizado 1.853 episodios de EI remitidos desde 26 centros españoles. De ellos, un 21,6% presentaban una alteración previa de la función renal. Desarrollaron IR de novo o un empeoramiento de la función renal previa un 38,7% de los casos. En aquellos pacientes que presentaban IR previa, el deterioro fue más frecuente (64 frente a 31,7%; p<0,001). Globalmente los pacientes con IR tenían más edad (70,6 frente a 67 años; p<0,01) y comorbilidades (índice de Charlson 5 frente a 4; p<0,01), y la EI era por Staphylococcus aureus (32,1 frente a 16,5%; p<0,01). El uso de AB potencialmente nefrotóxicos solo se asoció a IR en el grupo de pacientes sin IR previa (aminoglucósidos: OR=1,47 [IC 95% 1,096-1,988], p=0,010; aminoglucósidos-vancomicina: OR=1,49 [IC 95% 1,069-2,09], p=0,019]). Conclusiones: En pacientes sin IR previa, los AB nefrotóxicos se asocian a un deterioro de la función renal. En pacientes con IR previa al episodio de EI, el deterioro de renal fue más frecuente, pero parece estar más relacionado con la gravedad de la infección (AU)

Background and objectives: The possible renal toxicity of certain antibiotics (AB) is well known. The objective of our work is to know the possible effect of AB treatments in the development of renal failure (RF) in patients with infective endocarditis (IE). Material and method: Collection from a national multi-centre registry of collection on renal function, both prior and its impairment, if any, during the treatment of IE and in relation to possible causative factors, including the use of AB. Results: Between 2008 and 2012, 1,853 episodes of IE reported from 26 Spanish centres were analysed. Of these, 21.6% had prior RF. They developed new RF or impairment of renal function in 38.7% of the cases. In patients with prior RF, impairment was more frequent (64 vs. 31.7%, P<.001). Overall, patients with RF were older (70.6 vs. 67 years, P<.01), had more comorbidities (Charlson index 5 vs. 4, P<.01), and IE by Staphylococcus aureus (32.1 vs. 16.5%, P<.01). Potentially nephrotoxic AB use was only associated with RF in patients without prior RF (aminoglycosides: OR=1.47 [95% CI 1.096-1.988], P=.010; aminoglycosides with vancomycin: OR=1.49 [95% CI 1.069-2.09], P=.019). Conclusions: In patients without prior RF, the use of nephrotoxic AB is associated with impairment of renal function. In patients with RF prior to the IE episode, impairment of renal function was more frequent but appears to be more related to the severity of infection (AU)
