[Surgical treatment and prognostic factors in perihilar tumors]. / Khirurgicheskoe lechenie i faktory prognoza pri perikhilyarnoi opukholi.

OBJECTIVE: To study the results of surgical treatment in patients with perihilar tumors. MATERIAL AND METHODS: We analyzed 98 patients with perihilar tumors who underwent surgery. RESULTS: We prefer percutaneous transhepatic biliary drainage (n=58) for jaundice. Retrograde interventions were performed in 18 cases (20.5%), complications grade III-IV were more common (p=0.037) in the last group. Postoperative mortality was 12%. Complications developed in 81 patients (82.7%), grade ≥3 - in 39 (39.8%) cases. Portal vein resection (n=26) increased the incidence of complications grade ≥III (p=0.035) and portal vein thrombosis (p=0.0001). Chemotherapy after surgery was performed in 47 patients (48.0%), photodynamic therapy - in 7 (7.1%) patients. A 5-year overall survival was 28.1%, the median survival - 29 months. R2 resection and/or M1 stage (n=12) significantly worsened the prognosis and overall survival (16.5 vs. 31 months, p=0.0055). Lymph node (LN) lesion, microscopic status (R0 vs. R1) of resection margin, technique of decompression and isolated resection of extrahepatic bile ducts did not affect the prognosis, and we combined appropriate patients (n=72) for analysis. SI resection and excision of ≥6 lymph nodes were independent positive factors for disease-free survival (p=0.042 and p=0.007, respectively). Blood transfusion and high preoperative neutrophil-lymphocyte index (NLI ≥2.15) worsened overall (p=0.009 and p=0.002, respectively) and disease-free survival (p=0.002 and 0.007, respectively). The absence of adjuvant therapy worsened disease-free survival alone (p=0.024). CONCLUSION: SI liver resection, adequate lymph node dissection and adjuvant therapy should be used for perihilar tumors. Isolated resection of extrahepatic bile ducts is permissible in some cases. Blood transfusion and NLI ≥2.15 are independent negative prognostic factors.

Índice neutrófilo linfocito como predictor de infección del sitio quirúrgico en cirugía abdominal urgente

Introducción: Las infecciones del sitio quirúrgico representan una carga significativa en relación con la morbilidad, la mortalidad y costos adicionales. Por lo tanto, la prevención es importante. Objetivo: Comparar el índice neutrófilos-linfocitos con la escala SENIC para predecir infección del sitio quirúrgico en pacientes que sufrieron una cirugía abdominal de urgencia. Materiales y Métodos: Estudio transversal analítico, realizado en el Hospital de Alta Especialidad de Veracruz en expedientes de pacientes post-operados de urgencia, valorándose la escala SENIC (que incluye tipo de cirugía, duración del procedimiento, grado de asepsia de la intervención y 3 o más diagnósticos posoperatorios) y el índice neutrófilos-linfocitos (definido como la razón neutrófilos sobre linfocitos). Resultados: La edad promedio de los pacientes fue de 47,7 ± 18,7 años, con un predominio del sexo masculino 83 (62%), la estancia hospitalaria media fue de 29,7 ± 14,7 días, los procedimientos fueron la laparotomía exploradora en 57 (42,2%) y la apendicectomía en 26 (19,2%). Se aisló Escherichia coli en 27 (30%). Se obtuvo una sensibilidad de 69% y especificidad de 58% para el índice neutrófilos-linfocitos y para SENIC una sensibilidad 45% y una especificidad de 73%. Las estadísticas C para el índice neutrófilos-linfocitos y SENIC fueron 0,603 (IC: 0,524 − 0,682) y 0,668 (IC 95%: 0,588 − 0,749), respectivamente. Discusión y Conclusión: Ambos métodos muestran una precisión predictiva similar para infección del sitio quirúrgico, si bien calcular el índice neutrófiloslinfocitos es mucho más rápido y sencillo.

Introduction: Surgical site infections represent a significant burden in relation to morbidity, mortality, and additional costs. Therefore, prevention is important. Objective: To compare the neutrophil-lymphocyte index with the SENIC scale to predict surgical site infection in patients who underwent emergency abdominal surgery. Materials and Methods: Analytical cross-sectional study, carried out at the Hospital de Alta Especialidad de Veracruz in records of emergency post-operative patients, evaluating the SENIC scale (which includes type of surgery, duration of the procedure, degree of asepsis of the intervention and 3 or more postoperative diagnoses) and the neutrophil-to-lymphocyte ratio (defined as the ratio of neutrophils to lymphocytes). Results: The average age of the patients was 47.7 ± 18.7 years, with a predominance of males 83 (62%); the mean hospital stay was 29.7 ± 14.7 days, the procedures were exploratory laparotomy in 57 (42.2%) and appendectomy in 26 (19.2%). Escherichia coli was isolated in 27 (30%). A sensitivity of 69% and specificity of 58% was obtained for the neutrophil-lymphocyte index and for SENIC a sensitivity of 45% and a specificity of 73%. The C statistics for the neutrophil-lymphocyte ratio and SENIC were 0.603 (CI: 0.524 − 0.682) and 0.668 (95% CI: 0.588 − 0.749), respectively. Discussion and Conclusion: Both methods show similar predictive accuracy for surgical site infection, although calculating the neutrophil-lymphocyte ratio is much faster and easier.

Clinical-Immunological Correlates in Post-COVID-19 Endogenous Psychoses.

Objectives. To carry out a clinical and immunological study of the potential impact of coronavirus infection on the course of endogenous psychoses. Materials and methods. A total of 33 female patients aged 16-48 years with depressive-delusional states (F20.01, F21, F31) developing after coronavirus infections took part; group 1 consisted of 15 people who developed depressive-delusional states 1-2 months after COVID-19; group 2 consisted of 18 people with similar psychoses developing at later time points (2-6 months). The severity of psychopathological symptoms was assessed using the PANSS and HDRS-21 scales. The activity of inflammatory markers leukocyte elastase (LE) and α1-proteinase inhibitor (α1-PI) was determined in patients' blood. Absolute neutrophil and lymphocyte contents and their ratio (the neutrophil:lymphocyte index) were also evaluated. Standard values for indicators from healthy donors corresponding to patients in terms of age and sex were used as control values. Results. Endogenous psychosis developing at longer intervals after coronavirus infection (group 2) was found to be associated with "typical" inflammatory reactions, with increases in the activity of acute-phase proteins (α1-PI: 43.0 (35.6-49.7) IU/ml, p = 0.001) and neutrophil degranulation activity (LE - 254.8 (238.0-271.0) nmol/min·ml, p < 0.001), which was associated with the development of depressive-delusional states with dominance of manifestations of positive affectivity (anxiety, melancholy) and the extended nature of delusional disorders, which were mostly incongruent to affect. Conversely, development of endogenous psychosis during the first two months after COVID-19 (group 1) was characterized by a spectrum of inflammatory biomarkers with a decrease in neutrophil count ((2.6 ± 0.9)·109/liter, p < 0.05) and low LE activity (196 (172-209.4) nmol/min·ml, p < 0.001). This immunological profile was associated with predominance of manifestations of negative affectivity (apathy, asthenia, adynamia) in the structure of depressive-delusional states and the relatively undeveloped nature of delusional disorders, which were predominantly congruent to affect. Conclusions. The clinical and biological correlates found here presumptively indicate that experience of COVID-19 infection has a modulatory effect on neuroinflammation and the structure of endogenous psychosis.

Neutrophil/lymphocyte and monocyte/lymphocyte indexes as potential predictors of relapse at 1 year after diagnosis of pediatric multiple sclerosis: a single-center, exploratory and proof-of-concept study.

Introduction: Early identification of patients with a more unfavorable outcome in Multiple Sclerosis (MS) is crucial to optimize individualized treatment. Neutrophil-lymphocyte index (NLI) and monocyte-lymphocyte index (MLI) have been considered as potential biomarkers for disease prognosis. Our study aims to investigate the usefulness of NLI and MLI as predictors of relapse, disability progression, and lesion accumulation on magnetic resonance imaging (MRI) 1 year after diagnosis and treatment initiation, in pediatric-onset MS. Methods: A retrospective single-center study was conducted, including patients with diagnosis of MS established in pediatric age (<18 years old), at least 1-year of follow-up, and a complete blood count (CBC) performed at diagnosis. We collected the nearest-to-diagnosis NLI and MLI, as well as clinical and imaging variables, at diagnosis and 12 months later. Our cohort was further dichotomized into two groups, based on the presence of relapses. Statistical significance was considered for p < 0.05. Results: Eighteen patients (n = 18) were included. The relapsing group had higher mean, minimum, and maximum values for both NLI (5.17 ± 5.85, range: 1.57-11.92) and MLI (0.35 ± 0.22, range: 0.19-0.59), compared to the non-relapsing group (2.19 ± 1.63, range: 1.12-7.32 for NLI, and 0.24 ± 0.09, range: 0.14-0.44 for MLI). A higher percentage of patients in the relapsing group had increased NLI (>1.89, 66.7%) and MLI (>0.21, 66.7%) values than those in the non-relapsing group (46.7%). Patients who presented new T2-hyperintense lesions on MRI after 1 year of follow-up also had higher mean, minimum, and maximum values of both biomarkers. Patients who did not achieve No Evidence of Disease Activity-3 (NEDA-3) state exhibited higher values for both ratios. However, in our sample, no statistically significant correlations were found between MLI and NLI values and the clinical and imaging variables considered. Conclusion: The ease of obtaining NLI and MLI from routine blood tests renders them useful biomarkers as a screening tool in longitudinal follow-up. Our study was based on a very small sample size, but it allowed us to verify the feasibility of the protocol used. It is intended to involve other centers in the next phase of this work, testing the possible usefulness of the indices under analysis on a larger sample.

Correlación de los días de estancia hospitalaria con el índice neutrófilo-linfocítico en pacientes con diagnóstico de angina de Ludwig / Correlation of the days of hospital stay with the neutrophillymphocyte ratio in patients with a diagnosis of Ludwig's angina: pilot study

Introducción: El objetivo del presente estudio es correlacionar los días de estancia hospitalaria con el índice neutrófilo-linfocitico (INL) como biomarcador, en los pacientes con diagnóstico de angina de Ludwig que fueron admitidos en urgencias. Pacientes y métodos: Se realizó una búsqueda en los expedientes clínicos del hospital, donde solo se obtuvieron los que tenían diagnóstico de angina de Ludwig desde junio de 2016 hasta junio de 2020, y que cumplieran con los criterios de selección. Posteriormente se recabaron los datos sociodemográficos, días de hospitalización, biometría hemática y valores de neutrófilos y linfocitos para su posterior análisis estadístico. Resultados: Obtuvimos 21 pacientes (9 mujeres y 12 hombres). La edad promedio fue de 43,1 años (rango: 27-70 años). Se transformó la variable de días de hospitalización: en corta estancia hospitalaria aquellos pacientes que estuvieron hospitalizados 5 días o menos; y los de larga estancia hospitalaria aquellos pacientes que estuvieron hospitalizados 6 días o más, para el INL se consideró un índice alto aquellos pacientes que se encontraran con un INL ≥ 6 y un índice bajo aquellos pacientes con un índice ≤ 5, tomando en cuenta el punto de corte con respecto a estudios previamente realizados. Se observó que aquellos pacientes con un INL alto tuvieron una estancia hospitalaria larga, y de acuerdo con los resultados obtuvimos significación estadística (p = 0,02). Conclusiones: El INL parece ser un buen biomarcador para predecir los días de estancia hospitalaria de los pacientes con angina de Ludwig. Sin embargo, se necesitan más estudios para confirmar nuestros resultados. (AU)

Introduction: The aim of this study is to correlate the number of days of hospital stay with the neutrophil-lymphocyte index (NLI) as a biomarker in patients diagnosed with Ludwig's angina who were admitted to the emergency department. Patients and methods: A search was conducted in the hospital's medical records, where only those with a diagnosis of Ludwig's angina from June 2016 to June 2020 and that met the selection criteria were obtained. Afterwards, sociodemographic data, days of hospitalization, hematological parameters, and values of neutrophils and lymphocytes were collected for subsequent statistical analysis. Results: We obtained 21 patients (9 females and 12 males). The average age was 43.1 years (range: 27-70 years). The variable of days of hospitalization was transformed into: short hospital stay for patients who were hospitalized for 5 days or less, and long hospital stay for patients who were hospitalized for 6 days or more. For the NLI, a high index was considered for patients with an NLI ≥ 6 and a low index for patients with an NLI ≤ 5, taking into account the cut-off point with respect to previously conducted studies. We observed that patients with a high NLI had a long hospital stay and according to the results, we obtained statistical significance (p = 0.02). Conclusions: The NLI appears to be a good biomarker for predicting the number of days of hospital stay for patients with Ludwig's angina. However, more studies are needed to confirm our results.

[Clinical outcomes in cancer patients hospitalized with COVID-19]. / Evolución clínica de pacientes internados con cáncer e infección por COVID-19.

Cancer patients are exposed to more complications from COVID-19 than non-cancer patients. We report a cohort of 74 cancer patients (87.8% with solid neoplasia and 12.2% with hematological diseases) with COVID-19 infection admitted to a tertiary medical cancer center in Argentina. Pulmonary infiltrates were diagnosed at admission in 78.3% (N = 58) of the cases. COVID-19 infection was hospital-acquired in 20 (27.0%) patients. Thirty-nine patients (52.7%) received anticancer therapy within the 30 days prior to COVID-19 diagnosis; one was on radiation therapy. Twenty-four (32.4%) patients were admitted in the intensive care unit (ICU) and 18 (75.0%) required mechanical ventilation. All cause in-hospital mortality was 32.4% (N = 24) and ICU mortality was 62.5% (N = 15). Mortality under mechanical ventilation was 72.2% (N = 13). In the univariate analysis age, neutrophil count, neutrophil/lymphocyte index, D-dimer, ferritin, smoking, and nosocomial acquired infection were associated with in-hospital mortality. There were no statistically significant differences in mortality related to disease stage for solid tumors, neither cancer treatment within 30 days of COVID-19 diagnosis. Age and smoking were associated with mortality in the multivariate analysis. The adjusted odds ratios (95 CI) for age = 65 years and smoking were 8.87 (1.35-58.02) and 8.64 (1.32 - 56.64), respectively. Our experience can be useful for other institutions that assist cancer patients during the pandemic.

Los pacientes con cáncer y COVID-19 tienen más complicaciones que la población general. Comunicamos una cohorte de 74 pacientes con cáncer y COVID-19 internados en una institución oncológica. El 87.8% tenía diagnóstico de tumores sólidos y 12.2% oncohematológicos. Entre los tumores sólidos, el 61.5% presentó enfermedad metastásica. El 78.3% (N = 58) tenía infiltrados pulmonares al diagnóstico de COVID-19. La infección fue intrahospitalaria en 20 pacientes. Habían recibido tratamiento antineoplásico dentro de los 30 días anteriores al diagnóstico 39 pacientes (52.7%); uno se encontraba recibiendo radioterapia. Veinticuatro pacientes (32.4%) se derivaron a terapia intensiva (UTI) y 18 (75%) de ellos requirieron asistencia respiratoria mecánica (ARM). La mortalidad general durante la internación fue 32.4% (N = 24). La mortalidad en UTI fue 62.5% (N = 15). La mortalidad en ARM fue 72.2% (N = 13). La edad, recuento de neutrófilos, índice neutrófilo/linfocito, dímero D, ferritina, tabaquismo y haber adquirido la infección durante la internación resultaron estadísticamente significativos en el análisis univariado para mortalidad. No hallamos diferencias en mortalidad por estadio de enfermedad, en los pacientes con tumores sólidos, ni por haber recibido tratamiento antineoplásico dentro de los 30 días del diagnóstico de COVID-19. En el análisis multivariado con el modelo de regresión logística, solo la edad y el tabaquismo fueron predictores de mortalidad. Los odds ratios (IC 95) ajustados para la edad =65 años y el tabaquismo fueron 8.87 (1.35-58.02) y 8.64 (1.32-56.64), respectivamente. Este trabajo puede resultar de utilidad para instituciones polivalentes que asistan pacientes oncológicos durante la pandemia.

Indicadores de valor pronóstico de amputación en pacientes hospitalizados con pie diabético / Indicators of amputation´s prognostic value in hospitalized patients with diabetic foot

Introducción: La diabetes mellitus es la causa más importante de amputaciones no traumáticas en el mundo. El pronóstico de riesgo de amputación resulta vital para el tratamiento óptimo de los pacientes hospitalizados con pie diabético. Objetivo: Caracterizar las variables con valor pronóstico de amputación en pacientes hospitalizados con diagnóstico de pie diabético. Método: Se realizó un estudio analítico longitudinal prospectivo en el período desde diciembre de 2015 hasta diciembre de 2017, con una muestra constituida por 77 pacientes. Las variables recogidas fueron edad, sexo, resultados hemoquímicos al ingreso, co-morbilidad, control glucémico y amputaciones realizadas, estos dos últimos durante la estadía hospitalaria. Se hizo inclusión de las variables con asociación significativa en un análisis univariado (p < 0,05) en un modelo de regresión logística múltiple para evaluar su asociación independiente. Se determinaron los valores predictivos positivos, negativos, y el grado de sensibilidad y especificidad. Resultados: Los indicadores pronósticos resultantes del análisis de las variables fueron el índice leuco-hematocrito (p = 0,045), el nivel de albúmina en sangre (p = 0,004), la glicemia a mitad del ingreso (p = 0,045) y la glicemia al ingreso (p = 0,039). El índice leuco-hematocrito, menor de 6 al ingreso, se relacionó con una especificidad de 92 por ciento; la albúmina, menor de 29,9 g/L, presentó un valor predictivo positivo de 71 por ciento; la glicemia al ingreso, mayor de 21,5 mmol/L, mostró una sensibilidad de 75 por ciento; y la glicemia a mitad del ingreso, mayor de 12,9 mmol/L, manifestó una sensibilidad de 71 por ciento. Conclusiones: La evolución a la amputación de los pacientes ingresados por pie diabético se relaciona con el estado inflamatorio crónico, el estado nutricional y el control glucémico(AU)

Introduction: Diabetes mellitus is the most important cause of non-traumatic amputations in the world. The prognosis of amputation risk is vital for the optimal treatment of patients hospitalized with diabetic foot disease. Objective: Characterize variables with amputation´s prognostic value in hospitalized patients diagnosed with diabetic foot disease. Method: A prospective longitudinal analytical study was conducted in the period from December 2015 to December 2017, with a sample consisting of 77 patients. The variables collected were age, sex, hemochemical results upon admission, co-morbidity, glycaemic control and amputations performed, the latter two during the hospital stay. Variables with significant association were included in a one-variety analysis (p < 0.05) in a multiple logistic regression model to evaluate their independent association. Positive, negative predictive values, and the degree of sensitivity and specificity were determined. Results: The prognosis indicators resulting from the analysis of the variables were the leuko-hematocrit index (p = 0.045), the level of albumin in blood (p = 0.004), the glycaemia at the mid-time of the stay (p = 0.045) and the glycaemia at the admission time (p = 0.039). The leuko-hematocrit index, in less than 6 patients at admission time, was related to a specificity of 92 percent; albumin, in less than 29.9 g/L, had a positive predictive value of 71 percent; glycaemia at admission time, higher than 21.5 mmol/L, showed a sensitivity of 75 percent;and glycaemia at mid-time of the stay, higher than 12.9 mmol/L, showed a sensitivity of 71 percent. Conclusions: The evolution to amputation of patients admitted due to diabetic foot is related to chronic inflammatory state, nutritional state and glycaemic control(AU)

[Adult-onset Still's disease and the neutrophil-lymphocyte index in the Mexican population. A case series report]. / Enfermedad de Still del adulto y el índice neutrófilo/linfocito en población mexicana. Reporte de serie de casos.

BACKGROUND: In Mexico, adult-onset Still's disease (AOSD) is one of the causes of fever of unknown origin (FUO). The aim of this study is to describe a series of AOSD cases from a FUO cohort in order to know the clinical and biochemical characteristics of the cases, as well as to describe the neutrophil-lymphocyte index (NLI), which is a clinical marker of inflammation in autoimmune diseases. CASE REPORT: An observational study of 24 cases with AOSD; 72 % of them were women, the median age was 43 years (IQR 37.7-59.7), and the most frequent manifestations were classic rash (84 %) and arthralgia (100 %). All of them had tested negative for rheumatoid factor, antinuclear antibodies, and hyperferritinemia; 83 % had NLI > 3.08. The most used treatment was the combination of methotrexate with corticosteroids; seven patients required biological therapy, and one of them presented a hypersensitivity reaction. CONCLUSION: When there's FUO, the existence of AOSD should be suspected; also in the presence of rash, arthralgia, hyperferritinemia, and NLI > 3.08.

Antecedentes: En México, la enfermedad de Still del adulto (ESA) es una causa de fiebre de origen desconocido (FOD). El objetivo de este informe fue describir una serie de casos de ESA de una cohorte de FOD para conocer las características clínicas y bioquímicas, así como describir el índice neutrófilo/linfocito (INL), marcador clínico de inflamación en enfermedades autoinmunes. Caso clínico: Estudio observacional de 24 casos con ESA; 72 % fue del sexo femenino, la edad fue de 43 años (37.7-59.7) y las manifestaciones más frecuentes fueron rash clásico (84 %) y artralgias (100 %). Todos tuvieron factor reumatoide, anticuerpos antinucleares negativos e hiperferritinemia; 83 % tuvo INL > 3.08. El tratamiento más empleado fue la combinación de metotrexato y corticosteroides; siete pacientes ameritaron terapia biológica, uno presentó reacción de hipersensibilidad. Conclusión: Ante fiebre de origen desconocido, debe sospecharse ESA si, además, existe rash, artralgias, hiperferritinemia e INL > 3.08.

Validación del índice neutrófilo/linfocito predictivo de gravedad en el paciente oncológico quirúrgico / Validation of neutrophil/lymphocyte index predictive of severity in the surgical cancer patient

Introducción: La inflamación desempeña un papel protagonista en la fisiopatología del cáncer. Objetivo: Validar el índice neutrófilo/linfocito predictivo de gravedad en el paciente electivo oncológico quirúrgico. Métodos: Se realizó un estudio cuasiexperimental para un solo grupo en los pacientes quirúrgicos con el diagnóstico de enfermedad oncológica, intervenidos electivo por las diferentes especialidades quirúrgicas en el Hospital Oncológico Marie Curie en el período de enero a diciembre de 2019. Resultados: La curva Receiver Operating Characteristic se mostró asociada al modelo de regresión logística como estima el umbral de 0,23 por encima del cual se declarará la probabilidad de gravedad. En la validación entre los pacientes hay 23 que sí tuvieron riesgo de gravedad. Estos son los falsos positivos sobre los cuales se optimizó el preoperatorio. Conclusiones: El índice neutrófilo/linfocito mostró utilidad en predecir la gravedad en el paciente oncológico quirúrgico, y permitió individualizar el tratamiento prequirúrgico para que este tuviera mayor éxito(AU)

Introduction: Inflammation plays a leading role in the pathophysiology of cancer. Objective: To validate the predictive severity neutrophil/lymphocyte index in the elective surgical oncology patient. Methods: A quasi-experimental study was carried out for a single group in surgical patients diagnosed with oncological disease, electively operated by the different surgical specialties at Marie Curie Cancer Hospital from January to December 2019. Results: The Receiver Operating Characteristic curve was associated with the logistic regression model as it estimates the threshold of 0.23 above which the probability of severity will be declared. In the validation among the patients, there are 23 who did have a serious risk. These are the false positives on which the preoperative period was optimized. Conclusions: The neutrophil/lymphocyte index showed utility in predicting severity in the surgical oncology patient, and made it possible to individualize the pre-surgical treatment so that it would be more successful(AU)

Diferencia en el índice neutrófilos-linfocitos entre pacientes con síndrome de ovario poliquístico y sanas / Difference in neutrophil/lymphocyte index between patients with polycystic ovarian syndrome and healthy women

Resumen OBJETIVO: Determinar la correlación del índice neutrófilos-linfocitos entre mujeres sanas y con síndrome de ovario poliquístico con las concentraciones de glucosa, lípidos y andrógenos. MATERIALES Y MÉTODOS: Estudio descriptivo, retrospectivo, transversal y comparativo efectuado en el Hospital de Gineco-Obstetricia Luis Castelazo Ayala, entre julio de 2016 y febrero de 2019. Se estudiaron mujeres con síndrome de ovario poliquístico en quienes se cuantificaron: glucosa, lípidos, testosterona, androstenediona y sulfato de dehidroepiandrosterona. Con base en el reporte de la biometría hemática se calculó el índice neutrófilos-linfocitos. Los resultados se compararon con controles sanas estudiadas por infertilidad. Para el análisis estadístico se utilizó U de Mann-Whitney y análisis de correlación de Spearman. RESULTADOS: Se estudiaron 112 pacientes que se dividieron en dos grupos: el grupo 1 con síndrome de ovario poliquístico (n = 63) y grupo 2 mujeres sanas (n = 49). La mediana de la edad del grupo 1 fue 27 (14-39) la del grupo 2: 28 (16-41) años, sin diferencia estadísticamente significativa entre ambos ni entre los grupos en concentraciones de glucosa, colesterol y triglicéridos. El índice neutrófilos-linfocitos fue significativamente mayor en el grupo con síndrome de ovario poliquístico: 1.9 (0.9-7.4) vs 1.4 (0.8-3.9), p < 0.000, respectivamente. CONCLUSIÓN: El síndrome de ovario poliquístico se asocia con un proceso inflamatorio crónico y mayor riesgo cardiovascular.

Abstract OBJECTIVE: To determine the difference in the neutrophil/lymphocyte index between PCOS patients and healthy women. MATERIALS AND METHODS: Descriptive, retrospective, cross-sectional, comparative study. Women with PCOS were studied in which glucose, lipids, testosterone, androstenedione and dehydroepiandrosterone sulfate were measured, also a blood count was performed, and the neutrophil/lymphocyte index was calculated. The results were compared with healthy controls studied for infertility. For statistical analysis, Mann-Whitney U and Spearman correlation analysis were used. RESULTS: 112 patients divided as follows were studied: group I with PCOS (n = 63) and group II healthy women (n = 49). The median age was for group I: 27 (14-39) and group II: 28 (16-41) years without statistically significant difference between them, also there were not between the groups in the concentrations of glucose, cholesterol and triglycerides. The neutrophil/lymphocyte index was significantly higher in the group with PCOS, 1.9 (0.9-7.4) vs 1.4 (0.8-3.9), p < 0.000, respectively. CONCLUSION: PCOS is associated with a chronic inflammatory process that may confer greater cardiovascular risk.
