[COVID-19 readmissions during the first three epidemic periods in Orihuela, Spain: incidence, risk factors and letality]. / Reingresos por la COVID-19 durante los tres primeros periodos epidémicos en Orihuela, España: incidencia, factores de riesgo y letalidad.

OBJECTIVE: Readmission for COVID-19 is associated with high mortality, saturation of health services, and high costs. This study aimed to assess the incidence and risk factors of readmissions in COVID-19 patients in a regional hospital of Spain from February 2020 to March 2021. METHODS: A retrospective cohort study describing the characteristics of adult patients readmitted within thirty days of discharge after being infected with SARS-CoV-2 was carried out. Readmission associated risk factors were analysed using a binary logistic regression model. RESULTS: Of the 967 patients who survived their first COVID-19 admission, 70 (7.2%) were readmitted within thirty days. Of these, 34.3% presented pneumonia progression, 15.7% functional deterioration, and 12.9% other infections. The mortality rate during readmission was 28.6%. There were no statistically significant differences in the cumulative incidence of readmissions between the epidemic periods (p=0.241). Factors independently associated with readmission were: diabetes mellitus (aOR 1.96, 95%CI 1.07-3.57, p=0.030); acute kidney failure (aOR 2.69, 95%CI 1.43-5.07, p=0.002); not being a candidate for intensive care (aOR 7.68, 95% CI 4.28-13.80, p<0.001); and not being prescribed corticosteroids at discharge (aOR 2.15, 95% CI 1.04-4.44; p=0.039). CONCLUSIONS: A substantial proportion of patients admitted due to COVID-19 are readmitted, and they carry a high letality. Diabetes mellitus, acute kidney failure, not being a candidate for ICU admission, and not being prescribed corticosteroids on discharge are independently associated with an increased risk of readmission.

OBJECTIVE: Los reingresos por la COVID-19 se asocian a un incremento de la mortalidad, saturación de los servicios sanitarios y elevados costes. Este estudio pretendió evaluar la incidencia y los factores de riesgo de reingreso en pacientes con COVID-19 en un hospital comarcal español entre febrero de 2020 y marzo de 2021. METHODS: Se realizó un estudio sobre una cohorte que describía las características de los pacientes adultos reingresados en los treinta días siguientes al alta tras un ingreso por la COVID-19. Se analizaron los factores de riesgo asociados a reingreso mediante un modelo de regresión de logística binaria. RESULTS: De los 967 pacientes dados de alta de un primer ingreso por la COVID-19, 70 (7,2%) reingresaron en los treinta días siguientes. De ellos, el 34,3% presentó progresión de la neumonía, el 15,7% deterioro funcional y el 12,9% otras infecciones. La letalidad en el reingreso fue del 28,6%. No hubo diferencias estadísticamente significativas en la incidencia acumulada de reingreso entre los tres periodos (p=0,241). Los factores asociados de forma independiente con el reingreso fueron: diabetes mellitus (ORa: 1,96; IC 95%:1,07-3,57; p=0,030); insuficiencia renal aguda (ORa 2,69; IC del 95%: 1,43-5,07, p=0,002); no ser candidato a cuidados intensivos (ORa 7,68, IC 95% 4,28-13,80, p<0,001); y no tener prescritos corticosteroides al alta (ORa 2,15, IC 95% 1,04- 4,44; p=0,039). CONCLUSIONS: Una proporción sustancial de los pacientes ingresados por la COVID-19 reingresan, con una elevada letalidad. La diabetes mellitus, la insuficiencia renal aguda, no ser candidato a ingreso en UCI y no tener prescritos corticoides al alta se asocian con un mayor riesgo de reingreso.

Ivermectin Effect on In-Hospital Mortality and Need for Respiratory Support in COVID-19 Pneumonia: Propensity Score-Matched Retrospective Study.

INTRODUCTION: There is negligible evidence on the efficacy of ivermectin for treating COVID-19 pneumonia. This study aimed to assess the efficacy of ivermectin for pre-emptively treating Strongyloides stercoralis hyperinfection syndrome in order to reduce mortality and the need for respiratory support in patients hospitalized for COVID-19. METHODS: This single-center, observational, retrospective study included patients admitted with COVID-19 pneumonia at Hospital Vega Baja from 23 February 2020 to 14 March 2021. Because strongyloidiasis is endemic to our area, medical criteria support empiric administration of a single, 200 µg/kg dose of ivermectin to prevent Strongyloides hyperinfection syndrome. The outcome was a composite of all-cause in-hospital mortality and the need for respiratory support. RESULTS: Of 1167 patients in the cohort, 96 received ivermectin. After propensity score matching, we included 192 patients. The composite outcome of in-hospital mortality or need for respiratory support occurred in 41.7% of the control group (40/96) and 34.4% (33/96) of the ivermectin group. Ivermectin was not associated with the outcome of interest (adjusted odds ratio [aOR] 0.77, 95% confidence interval [CI] 0.35, 1.69; p = 0.52). The factors independently associated with this endpoint were oxygen saturation (aOR 0.78, 95% CI 0.68, 0.89, p < 0.001) and C-reactive protein at admission (aOR: 1.09, 95% CI 1.03, 1.16, p < 0.001). CONCLUSIONS: In hospitalized patients with COVID-19 pneumonia, ivermectin at a single dose for pre-emptively treating Strongyloides stercoralis is not effective in reducing mortality or the need for respiratory support measures.

Strongyloidiasis in Southern Alicante (Spain): Comparative Retrospective Study of Autochthonous and Imported Cases.

BACKGROUND: Strongyloidiasis is a parasitic disease with global prevalence. In Spain, autochthonous cases are concentrated in the Mediterranean basin. We aimed to analyze clinical and epidemiological characteristics of Strongyloides stercoralis infection in Vega Baja del Segura (Spain), comparing autochthonous versus imported cases. METHODS: Observational retrospective study of all strongyloidiasis cases from January 2009 to January 2019. Cases were diagnosed by stool larvae visualization, positive culture, PCR, Strongyloides serology, and/or compatible histology. RESULTS: We included 36 patients (21 men) with a mean age of 60.8 years ±17.6; 15 cases were autochthonous and 21 imported 80.9% from Latin America. Autochthonous cases were associated with older age (mean 71.3 vs. 53.3 years; p = 0.002), male sex (odds ratio (OR) 5.33; 95% confidence interval (CI) 1.15-24.68; p = 0.041), and agricultural activity (OR 13.5; 95% CI 2.4-73.7; p = 0.002). Fourteen were asymptomatic, three autochthonous cases presented with hyperinfection syndrome, and two patients died. There was no difference between autochthonous versus imported origin in eosinophilia at diagnosis (93.3% vs. 75%; p = 0.207), treatment received, or clinical response (85.7% vs. 88.9% cured; p = 1). CONCLUSION: In our region, imported strongyloidiasis coexists with autochthonous cases, which are mainly in older male farmers who are diagnosed at more advanced stages. Systematic screening programs are needed.
