RESUMO

Introduction: Subjects with asymptomatic infections are not generally admitted to health care facilities, however, they may benefit from antiviral therapy. Objective: To evaluate the contribution to treatment with combined therapy based on recombinant human interferon alpha 2b + Lopinavir/Ritonavir + Chloroquine versus Lopinavir/Ritonavir + Chloroquine in asymptomatic and symptomatic patients. Material and Methods: An observational study was carried out in patients with a positive diagnosis of COVID-19 from April 1st to July 30th, 2020. From a total of 308 patients treated with interferon + Lopinavir/Ritonavir + Chloroquine, we selected a statistically representative sample of 40 patients using a simple randomization process. As a control group, 27 patients who only received treatment with Lopinavir/Ritonavir + Chloroquine were selected. These patients underwent determinations of anti-SARS-CoV-2 antibodies, determinations of inflammatory markers, and follow-up by RT-PCR to evaluate the time length of negativization. Results: The group treated with interferon had a significantly shorter time to negativization. Patients treated with interferon showed a significant decrease in inflammatory markers at the time of hospital discharge and they had an increase in antibody titers at two and four months after hospital discharge, compared to the group of patients who did not receive interferon. Conclusions: The treatment with exogenous interferon in patients with COVID-19 had a significant contribution to the regulation of the immune response of the patients(AU)


Introducción: Los sujetos con infección asintomática generalmente no son admitidos en centros de asistencia médica, sin embargo, pueden beneficiarse de la terapia antiviral. Objetivo: evaluar la contribución al tratamiento de la terapia combinada basada en interferón alfa 2b recombinante humano + Lopinavir/Ritonavir + Cloroquina contra Lopinavir/Ritonavir + Cloroquina en pacientes asintomáticos y sintomáticos. Material y Métodos: Se realizó un estudio observacional en pacientes con diagnóstico positivo de COVID-19, durante los días del 1 de abril al 30 de julio de 2020. De un total de 308 pacientes tratados con interferón + Lopinavir/Ritonavir + Cloroquina, se seleccionaron mediante un proceso de aleatorización simple, una muestra estadísticamente representativa de 40 pacientes. Como grupo control se seleccionaron 27 pacientes que solo recibieron tratamiento con Lopinavir/Ritonavir + Cloroquina. Estos pacientes se sometieron a determinaciones de anticuerpos anti-SARS-CoV-2, determinaciones de marcadores inflamatorios y seguimiento por RT-PCR para evaluar el tiempo de negativización. Resultados: El grupo tratado con interferón tuvo un tiempo significativamente más corto de negativización. Los pacientes tratados con interferón mostraron una disminución significativa de los marcadores inflamatorios en el momento del alta hospitalaria y tuvieron un incremento de los títulos de anticuerpos a los dos y cuatro meses posteriores al alta hospitalaria, en comparación con el grupo de pacientes que no recibió interferón. Conclusiones: El tratamiento con interferón exógeno en pacientes con COVID-19 tuvo una contribución significativa en la regulación de la respuesta inmune de los pacientes(AU)

RESUMO

Introducción: El Helicobacter pylori (HP) causa inflamación local en el estómago y una respuesta inmunitaria humoral sistémica. En los estudios que investigaron la asociación entre la infección por HP y el índice de neutrófilos/linfocitos (INL) y el volumen plaquetario medio (VPM) en adultos, no se observó ninguna relación. Hasta donde sabemos, no se hicieron estudios en niños. Nuestro objetivo fue evaluar la asociación entre los valores de INL y VPM y la infección por HP, la clasificación de la gravedad y el estado antes y después del tratamiento.Población y métodos: En el estudio se incluyeron pacientes de 2 a 18 años de edad con dispepsia y sin enfermedades crónicas sometidos a una endoscopía alta. Se hizo una biopsia endoscópica de la mucosa y se determinaron la presencia de HP y la gravedad de la infección según la clasificación de Sídney.Resultados: Se incluyeron en el estudio 153 pacientes con HP y 211 sin HP; la media de edad fue de 13,3 ± 3,4 años y 13,1 ± 3,5 años, respectivamente. No se observaron diferencias estadísticamente significativas entre los pacientes con y sin HP ni tampoco entre los subgrupos de pacientes con HP según la gravedad en relación con el INL y el VPM (p > 0,05).Conclusiones: No se observó una asociación entre los valores de INL y VPM y la infección por HP, la clasificación de la gravedad ni el estado antes y después del tratamiento.


Introduction: HP causes local inflammation in the stomach and a systemic humoral immune response. No relationship was found in adult studies investigating the association between HP infection and neutrophil/lymphocyte ratio (NLR) and mean platelet volume (MPV). To our knowledge, there is no study in children. We aimed to evaluate the association between NLR and MPV values with HP infection, severity classification, and pre- and post-treatment status.Population and Methods: Patients with dyspepsia aged between 2-18 years and without any chronic diseases undergoing gastroduodenoscopy were included in the study. Endoscopic mucosal biopsy was performed, HP presence and infection severity were determined according to Sydney Classification.Results: 153 patients with HP positivity and 211 patients with HP negativity were included in the study, the mean age of them was 13.3 ± 3.4 years and 13.1 ± 3.5 years, respectively. No statistically significant difference was found between patients with HP positive and negative patients and also between severity subgroups of HP positive patients in terms of NLR and MPV (p > 0.05).Conclusions:There was no association between NLR and MPV values with HP infection, severity classification, or pre- and post-treatment status.

RESUMO

Objective · To explored the correlation of preoperative peripheral blood neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) with clinical characteristics and prognosis of ovarian cancer. Methods · Patients' clinicopathological data of 127 cases of benign tumors and 286 cases of malignant tumor were collected, and the correlation between the level NLR and PLR in patients with ovarian cancer clinical pathology indicators and overall survival was analyzed. Results · preoperative NLR and PLR levels in patients with ovarian cancer were higher than those in benign tumors(P=0.000). The optimal cut-off point of NLR and PLR were 3.0 and 151. There was statistical significant difference between the high level of NLR group (NLR ≥ 3) and the low level of NLR group in pathological type, FIGO staging, lymph node metastasis, CA125 level and the amount of ascites (P<0.05). There was statistical significant difference between the high level of PLR group (PLR ≥ 151) and the low level of PLR group in FIGO stage,transfer status, CA125 level and quantity of ascites (P<0.05). The median survival time for NLR/PLR in the high level group were 33 and 33.5 months lower than that ofthe corresponding group of 44.5 and 49.5 months (P=0.044, P=0.000). Multivariate Cox regression analysis showed that PLR ≥ 151 were independent risk factors affectOS in ovarian cancer patients (HR=1.936, 95% CI=1.013-3.698, P=0.045). Conclusion · The elevated blood preoperative PLR indicates poor prognosis of ovarian cancer patients. Preoperative PLR may serve as an important independent prognostic factor for ovarian cancer patients.
