Effect of empagliflozin in peripheral diabetic neuropathy of patients with type 2 diabetes mellitus.

BACKGROUND: Diabetic peripheral neuropathy (DPN) is the most dominant cause of neuropathy worldwide, and there has been no specific treatment until now. The aim of the current study was to assess the probable protective effect of empagliflozin in type 2 diabetics who are suffering from DPN. METHODS: Fifty eligible type 2 diabetes mellitus (T2DM) cases with diabetic peripheral neuropathy were recruited in this study and classified into 2 groups. Group I (n=25) (control group) received placebo tablets once daily. Group II (n=25) (empagliflozin group) received empagliflozin 25mg once daily for three months. Empagliflozin efficacy was evaluated using electrophysiological studies, and HbA1c levels, the brief pain inventory short-form item (BPI-SF) score, the diabetic neuropathy symptom (DNS) score, the atherosclerotic cardiovascular disease (ASCVD) risk score, and the serum levels of neuron-specific enolase (NSE), malondialdehyde (MDA) and calprotectin (Calpro), lipid profile, and random blood glucose level (RBG). RESULTS: After three months, comparing the results of the empagliflozin arm to the control arm showed a significant improvement in the electrophysiological studies and a significant decrease in the BPI-SF score and the mean serum levels of NSE and MDA. However, no significant difference was determined in HbA1c, Calpro, lipid profile, and RBG levels. In addition, the DNS and ASCVD risk scores were not significantly different. The NSE and MDA levels were significantly negatively correlated with the electrophysiological parameters. However, the BPI-SF score showed a non-significant difference. CONCLUSIONS: Empagliflozin may be a promising neuroprotective and therapeutic agent for diabetic peripheral neuropathy. Trial registration Identifier: NCT05977465.

Manejo racional de las neuropatías diabéticas: consenso multidisciplinario de expertos / Rational management of the diabetic neuropathies: a multidisciplinary expert group consensus

Resumen: La diabetes mellitus, un padecimiento crónico y progresivo, ocupó el tercer lugar en defunciones durante el período comprendido de enero a junio de 2021 en México. Su complicación crónica más frecuente es la neuropatía diabética que tiene un impacto importante en el sistema nervioso. En la Ciudad de México se reunió un grupo multidisciplinario de expertos para establecer un algoritmo de tratamiento que considere los aspectos sintomáticos y etiopatogénicos de la neuropatía diabética. Se utilizó un método Delphi en tiempo real con dos rondas de preguntas interactivas. La implementación del algoritmo propuesto permitirá abordar de manera integral al paciente diabético con neuropatía dolorosa y no dolorosa, tanto en el terreno de los síntomas como en la etiopatogenia. Este abordaje brinda la oportunidad de mejorar la calidad de vida y lograr la reinserción a la vida familiar y laboral. El panel de expertos recomienda al ácido tióctico como tratamiento etiopatogénico de primera línea en la neuropatía diabética.

Abstract: Diabetes mellitus, a chronic and progressive condition, was the third most common cause of death in Mexico between January and June 2021. Its most frequent chronic complication is diabetic neuropathy, which has a major impact on the nervous system. A multidisciplinary group of experts met in Mexico City to establish a treatment algorithm considering the symptomatic and etiopathogenic aspects of diabetic neuropathy. A real-time Delphi method with two rounds of interative questions was used. The implementation of the proposed algorithm will allow a comprehensive approach to the diabetic patient with painful and non-painful neuropathy, both in terms of symptoms and etiopathogenesis. This approach provides the opportunity to improve quality of life and achieve reintegration into family and work life. The expert panel recommends thioctic acid as the first line etiopathogenic treatment for diabetic neuropathy.

Early diagnosis of diabetic neuropathy and prophylaxis of diabetic foot / Diagnóstico precoce da neuropatia diabética e profilaxia do pé diabético

Introduction: the diabetic foot is one of the most serious complications of diabetes mellitus. About 50% of non-traumatic amputations occur in these patients. In addition, it is an important public health problem and constitutes a chronic and complex metabolic disorder that is characterized by impaired metabolism of glucose and other complications in essential organs for the maintenance of life. Objective: to evaluate the sensitivity and specificity of diabetic neuropathy using the Michigan self-assessment and physical examination in type 1 and type 2 diabetics. Methods: this is a cross-sectional study. The "Michigan Neuropathy Screening Instruments" classification was used to assess the degree of peripheral neuropathy, in which participants answered the questionnaire and were evaluated for the presence of foot lesions. All participants were stratified by the risk of developing foot ulcers according to the IWGDF protocol. Results: the sample had 200 participants. Regarding the IWGDF classification, 23 patients were classified as moderate risk (11.50%) and 61 as high risk for developing foot ulcers (30.50%). Using a cutoff of 2.5 on the physical examination score to diagnose neuropathy, a sensitivity of 97.62% and a specificity of 47.41% were obtained. Using a score greater than or equal to 6 in the self-assessment for the diagnosis of neuropathy, a sensitivity of 50.00% and a specificity of 94.83% were found. Conclusion: the association of the Michigan physical examination (high sensitivity) with self-assessment (high specificity) increases the accuracy for the diagnosis of diabetic neuropathy

Introdução: o pé diabético é uma das complicações mais sérias do diabetes mellitus. Cerca de 50% das amputações não traumáticas ocorrem nesses pacientes. Além disso, é um importante problema de saúde pública por ser um distúrbio metabólico crônico e complexo que se caracteriza pelo comprometimento do metabolismo da glicose associada a outras complicações em órgãos essenciais para manutenção vital. Objetivo: avaliar a sensibilidade e especificidade para neuropatia diabética da autoavaliação e do exame físico de Michigan nos diabéticos tipo 1 e tipo 2. Método: trata-se de um estudo transversal. Foi utilizada a classificação "Michigan Neuropathy Screening Instruments" para avaliação do grau de neuropatia periférica, em que os participantes responderam ao questionário e foram avaliados quanto a presença de lesões nos pés. Todos os participantes foram estratificados quanto ao risco de desenvolver úlcera nos pés de acordo com o protocolo do IWGDF. Resultados: a amostra contou com 200 participantes. Quanto à classificação do IWGDF, 23 pacientes foram classificados como risco moderado (11,50%) e 61 como alto risco para o desenvolvimento de úlceras nos pés (30,50%). Utilizando-se um corte de 2,5 na pontuação do exame físico para diagnosticar a neuropatia, foi obtida uma sensibilidade de 97,62% e uma especificidade de 47,41%. Utilizando-se uma pontuação maior ou igual a 6 na autoavaliação para o diagnóstico de neuropatia, foi obtida uma sensibilidade de 50,00% e uma especificidade de 94,83%. Conclusão: a associação do exame físico de Michigan (alta sensibilidade) com a autoavaliação (alta especificidade) tem melhor acurácia para o diagnóstico de neuropatia diabética.

Introduction: Diabetic neuropathy is the most frequent complication of diabetes mellitus and one of its possible consequences is diabetic foot syndrome. First level of care physicians should know the clinical behavior of diabetic neuropathy and, above all, how it influences the appearance and development of diabetic foot syndrome. Objective: To describe the role of diabetic neuropathy in the appearance and development of diabetic foot syndrome. Methods: To obtain the information, SciELO, PubMed and Google Scholar were used as search engines for scientific information. The keywords used were: diabetes mellitus; diabetic neuropathy; diabetic foot; diabetic foot syndrome; diabetic foot ulcer; diabetic foot attack. Different review papers, research papers and web pages were evaluated and articles that were more than 10 years old and published in languages other than Spanish, Portuguese and English and that did not refer to the subject of the study through the title were excluded. This allowed the citation of 45 bibliographic references. Conclusions: Diabetic neuropathy constitutes the main risk factor in the appearance and development of diabetic foot syndrome, especially when associated with arthropathy (foot defects), peripheral vascular disease and/or sepsis. Glycemic control, early detection of the foot at risk and preventive care of the lower limbs will have a favorable impact on the patient's health and well-being(AU)

Which field test should be used to compare the functional exercise capacities of patients with type 2 diabetes mellitus with and without diabetic peripheral neuropathy? Cross-sectional study.

BACKGROUND: The 6-minute step test (6MST) has begun to be used as a simple and effective alternative for assessing functional exercise capacity. There is no study using 6MSTs to evaluate the exercise capacities of patients with type 2 diabetes mellitus (DM) with and without diabetic peripheral neuropathy (DPN). OBJECTIVE: To compare the cardiorespiratory responses of the 6-minute walk test (MWT) and the 6MST exercise tests and to analyze the usability of the 6MST in Type 2 DM patients with and without neuropathy. METHODS: 32 non-neuropathic Type 2 DM, 32 neuropathic Type 2 DM patients, and 30 healthy volunteers were included in this cross-sectional study. Functional exercise capacity was evaluated with the 6MWT and the 6MST. The 30-second sit-stand test (30s STS) was used to evaluate general lower extremity muscle strength and function. RESULTS: There was a significant difference in the results of 6MWT (m), 6MST (number of steps), and 30s STS of the three groups (p<0.05). The 6MST results of patients with neuropathic Type 2 DM were significantly lower than those of non-neuropathic diabetics and those who were healthy (number of steps; 114.07±25.57 vs. 133.48±33.57 vs. 160.35±28.52, respectively) (p=0.001). The change in cardiorespiratory response in systolic blood pressure, heart rate, perceived dyspnea, and leg fatigue severity was significantly higher at 6MST than 6MWT in the three groups (p<0.05). 6MST was correlated with 6MWT (r=0.679, p=0.001), and 30s STS (r=0.589, p=0.001) in patients with Type 2 DM. CONCLUSIONS: Cardiorespiratory responses increased more in 6MST compared to 6MWT. In patients with Type 2DM, 6MWT and 6MST were moderately correlated with each other. 6MST is an effective and safe assessment method that may better reveal the differences in functional exercise capacity between neuropathic and non-neuropathic individuals in clinics.

Association of peripheral neuropathy with skeletal muscle mass and function in type two diabetes mellitus patients: A cross-sectional study.

BACKGROUND & OBJECTIVE: Diabetic peripheral neuropathy (DPN) is considered to be a risk factor for development of sarcopenia. Therefore, our study aimed to detect the association between peripheral neuropathy with skeletal muscle mass and function in type two diabetes mellitus (T2DM) patients. METHODS: A total of 176 participants, ≥45 years were included in the study. Out of 176, 60 were healthy volunteers, 60 had T2DM without neuropathy, 56 had T2DM with neuropathy. In all the participants peripheral nerve function was assessed by nerve conduction studies (Common peroneal and Sural nerve) and sarcopenia parameters were evaluated according to the Asian Working Group for Sarcopenia (AWGS) criteria. RESULTS: The present study suggested that diabetic peripheral neuropathy (DPN) was associated with decline in muscle mass, which was found only in men. Our study showed a positive correlation between appendicular skeletal muscle index (ASMI) and common peroneal nerve amplitude and sural nerve amplitude with r=0.527, p<0.05; r=0.847, p<0.001 respectively. Furthermore, in multiple linear regression analyses, we found a positive relationship between ASMI and sural nerve amplitude after adjustment for confounders like age, duration of diabetes, and HbA1C (B=0.739; p<0.001). CONCLUSION: As DPN patients are more prone to developing sarcopenia, and periodic assessment of skeletal muscle mass and function is warranted to initiate early lifestyle interventions in these patients, which will improve their quality of life.

An experimental study of tangzhouling on morphological changes of nissl bodies in the dorsal root ganglion of DM rats / Un estudio experimental de tangzhouling sobre los cambios morfológicos de los cuerpos de nissl en el ganglio de la raíz dorsal de ratas DM

SUMMARY: This study aims to investigate the effect of Tangzhouling on the morphological changes of Nissl bodies in the dorsal root ganglion of DM Rats. In this study, 69 rats were randomly divided into a control group (n = 10) and a model group (n = 59). The rats in the model group were randomly divided into a diabetic group (n = 11), a vitamin C group (n = 12), a low dose Tangzhouling group (n = 12), a medium dose Tangzhouling group (n = 12) and a high dose Tangzhouling group (n = 12). The dose of Tangzhouling in the low dose group was 5 times that of the adult dose, being 0.44g/kg/d. The dose of Tangzhouling in the medium dose group was 10 times that of the adult dose, being 0.88g/kg/d. The dose of Tangzhouling in the high dose group was 20 times that of the adult dose, being 1.75g/kg/d. All doses above are crude drug dosages. Rats in the vitamin C group were given 10 times the dose of an adult, being, 0.05 g/ kg/d. The diabetic group and the control group were given the same amount of distilled water. Drug delivery time is 16 weeks. The dorsal root ganglion was placed in a freezing tube at the end of the experiment. The morphological changes of Nissl bodies in the dorsal root ganglion were detected by HE and Nissl staining. The study results showed that vitamin C had no significant effect on the quantity, size and nucleolus. Tangzhouling can improvee the morphology, quantity and nucleolus of Nissl bodies to a certain extent, and the high dose is better than the lower dose. Tangzhouling capsules can improve the nerve function of DM rats through Nissl bodies.

RESUMEN: Este estudio tuvo como objetivo investigar el efecto de Tangzhouling en los cambios morfológicos de los cuerpos de Nissl en el ganglio de la raíz dorsal de las ratas DM. En este estudio, 69 ratas se dividieron aleatoriamente en un grupo control (n = 10) y un grupo modelo (n = 59). Las ratas del grupo modelo se dividieron aleatoriamente en un grupo diabéticos (n = 11), un grupo vitamina C (n = 12), un grupo de dosis baja de Tangzhouling (n = 12), un grupo de dosis media de Tangzhouling (n = 12) y un grupo de dosis alta de Tangzhouling (n = 12). La dosis de Tangzhouling en el grupo de dosis baja fue 5 veces mayor que la dosis del adulto, siendo 0,44 g/kg/d. La dosis de Tangzhouling en el grupo de dosis media fue 10 veces mayor que la dosis del adulto, siendo 0,88 g/kg/d. La dosis de Tangzhouling en el grupo de dosis alta fue 20 veces mayor que la dosis del adulto, siendo 1,75 g/kg/d. Todas las dosis anteriores son dosis de fármaco crudo. Se les administró 10 veces la dosis de un adulto a las ratas del grupo vitamina C, siendo 0,05 g/kg/d. El grupo de diabéticos y el grupo de control recibieron la misma cantidad de agua destilada. El tiempo de entrega del fármaco fue de 16 semanas. El ganglio de la raíz dorsal se colocó en un tubo de congelación al final del experimento. Los cambios morfológicos de los cuerpos de Nissl en el ganglio de la raíz dorsal se detectaron mediante tinción de HE y Nissl. Los resultados del estudio mostraron que la vitamina C no tuvo un efecto significativo sobre la cantidad, el tamaño y el nucléolo. Tangzhouling puede mejorar la morfología, la cantidad y el nucléolo de los cuerpos de Nissl hasta cierto punto, y es mejor la dosis alta que la dosis baja. Las cápsulas de Tangzhouling pueden mejorar la función nerviosa de las ratas DM a través de los cuerpos de Nissl.

Impacto del síndrome de apnea-hipopnea del sueño en la neuropatía diabética. Revisión sistemática / Impact of sleep apnoea-hypopnoea syndrome on diabetic neuropathy. A systematic review

Introducción: La diabetes mellitus y el síndrome de apnea-hipopnea del sueño parecen estar relacionados, pero no está bien definido si en los pacientes con ambas enfermedades existe un mayor riesgo de neuropatía periférica. Para ello, realizamos una revisión sistemática.MétodosBúsqueda bibliográfica en 3 bases de datos electrónicas usando una estrategia predefinida y la metodología PRISMA. Solamente se incluyeron estudios originales (cualquier tipo de diseño) y publicados a partir del año 2000 en inglés, francés, portugués o español. Se estableció una escala de calidad de los estudios.ResultadosSe seleccionaron 12 artículos, de los que 6 estudiaban pacientes diabéticos tipo 2. La prevalencia global de síndrome de apnea-hipopnea del sueño fue del 43,7% (1.559/3.564 pacientes). La neuropatía diabética fue más frecuente en los pacientes con síndrome de apnea-hipopnea del sueño en 9 estudios, aunque solo en 4 de manera significativa (60 vs. 27%, p<0,001; 64,5 vs. 36%, p=0,03; 37 vs. 23,4%, p<0,02; 66,6 vs. 0%, p=0,007). En un estudio, la neuropatía diabética fue más frecuente en los pacientes sin síndrome de apnea-hipopnea del sueño (aunque sin significación estadística) y en 2 no se hizo la comparación entre pacientes con/sin síndrome de apnea-hipopnea del sueño.ConclusionesLos resultados observados indican una relación entre diabetes mellitus y síndrome de apnea-hipopnea del sueño en la aparición de neuropatía diabética.

Introduction: Diabetes mellitus and sleep apnoea-hypopnoea syndrome appear to be related, but it is not well defined whether there is an increased risk of peripheral neuropathy in patients with both diseases. For this reason, we conducted a systematic review.MethodsBibliographic search in 3 electronic databases using a predefined strategy and the PRISMA methodology. Only original studies (any type of design) published from 2000 onwards in English, French, Portuguese or Spanish were included. A study quality scale was established.ResultsTwelve articles were selected, of which six studied type 2 diabetic patients. The overall prevalence of sleep apnoea-hypopnoea syndrome was 43.7% (1,559/3,564 patients). Diabetic neuropathy was more frequent in patients with sleep apnoea-hypopnoea syndrome in nine studies, although significantly only in four (60% vs 27%, P<.001; 64.5% vs 36%, P=.03; 37% vs 23.4%, P<.02; 66.6% vs 0%, P=.007). In one study, diabetic neuropathy was more frequent in patients without sleep apnoea-hypopnoea syndrome (although not statistically significant) and in 2 no comparison was made between patients with/without sleep apnoea/hypopnoea syndrome.ConclusionsThe observed results suggest a relationship between diabetes mellitus and sleep apnoea-hypopnoea syndrome in the occurrence of diabetic neuropathy.

Background and objective: Diabetic neuropathy is a complication of type 2 diabetes, it´s present in 95 % of patients, affecting the individual, family and social environment. The objective is to identify the epidemiological profile of pain secondary to moderate diabetic peripheral neuropathy. Materials and methods: Descriptive cross-sectional study of pain using as a source of information the patient with moderate peripheral neuropathy secondary to type 2 diabetes. The severity of diabetic peripheral neuropathy was established with the Michigan scale. The sample size was 145 patients. The epidemiological profile of pain evaluated with the McGill multidimensional questionnaire, Cronbach's alpha 0.88; it is assesses the intensity of pain in three independent categories (total pain assessment index [sensory, affective and evolutionary dimension], overall total intensity and current total intensity) and within each of them identifies the specific characteristics of pain. Statistical analysis included means, standard deviation, confidence interval for means, and percentages. Results: Total pain assessment index 9.74 ± 1.40 (95 % CI; 9.51-9.97), sensory dimension 5.02 ± 0.84 (95 % CI; 4.88-5.16), affective dimension 3.75 ± 0.94 (95 % CI; 3.59-3.90), and evolutionary dimension 0.96 ± 0.18 (95 % CI; 0.93-1.00). Specific characteristics of the total pain assessment Index identify shaking 35.2 %, burning 31.0 %, suffocating 40.0 %, exhausting 33.1 %, depressing 29.7 % and constant 35.2 %. Total general intensity of pain 7.70 ± 1.29 (95 % CI;7.49-7.91). Current total intensity 40.7 % "intense". Conclusion: The epidemiological profile of pain is of high intensity, burning, penetrating, fixed or diffuse, accompanied by generally constant itching, with negative emotional repercussions, including feelings of anxiety, secondary to depressing, exhausting, suffocating and mortifying pain.(AU)

Estudio de factores de riesgo para el desarrollo de pie diabético: Campaña 1N / A study of risk factors in the development of diabetic foot: 1N Campaign

Introducción: el examen del pie es fundamental en pacientes con diabetes mellitus (DM). La correcta evaluación del pie en el paciente que concurre a control diabetológico es clave para establecer factores de riesgo para el desarrollo de úlceras, detectar lesiones, tomar medidas preventivas, realizar una derivación temprana y educar en cuidados del pie. Objetivos: en este estudio se examinaron los pies de personas con DM durante la Campaña de Concientización y Prevención del Pie Diabético el 1º de noviembre de 2019 con el fin de evaluar la presencia de síntomas y signos relacionados con neuropatía, enfermedad vascular periférica, y prevalencia de los mismos, y conocer el riesgo. Materiales y métodos: se analizaron 165 pacientes en cuatro centros: Sanatorio Güemes (Servicio de Diabetes y Endocrinología), PREDIGMA (Centro de Medicina Preventiva, Posadas, Misiones), Hospital Central de San Isidro, Nexo Centro Médico (Ciudad de Junín) y Hospital Municipal de General Viamonte (Provincia de Buenos Aires). Resultados: se encontró que el 43,6% presentaba algún síntoma en miembros inferiores y hasta el 57% alteración en las pruebas de tamizaje de neuropatía diabética o enfermedad arterial periférica, con mayor prevalencia a mayor tiempo de evolución de la DM. Los signos más frecuentemente hallados en el examen físico fueron: piel seca (71,5%), distrofia ungueal (60,6%) o alteración de la almohadilla plantar (52,1%). Las comorbilidades más frecuentes fueron: hipertensión (74,5%) y dislipemia (73,3%). La mediana de hemoglobina glicosilada fue de 7,40% (6,70-8,10), mayor en personas con antecedentes de retinopatía (7,8%; p<0,01) y en pacientes que refirieron tener calambres (7,85 a 7,30; p=0,03) o ardor (8,0 vs 7,3; p<0,01). El porcentaje de pacientes con pie de alto riesgo por antecedentes, inspección o tamizaje de neuropatía o enfermedad vascular representó desde el 40% en aquellos con DM de menos de cinco años de evolución hasta el 86% en quienes tenían más de 20 años. Conclusiones: el elevado porcentaje de pacientes con pie de riesgo identificado en este estudio sugiere que, además del correcto examen físico, se requiere la toma de conductas por parte del médico tratante, como la indicación de plantillas o calzado adecuado, así como una fluida derivación al técnico en ortesis, traumatólogo o fisiatra.

Introduction: foot examination is essential in patients with diabetes mellitus (DM). The correct evaluation of the foot in the patient who attends diabetes control is key to establish risk factors for the development of ulcers, detect injuries, take preventive measures, make an early referral and educate in foot care. Objectives: in this study, the feet of people with DM were examined during the Diabetic Foot Awareness and Prevention Campaign on November 1, 2019 in order to assess the presence of symptoms and signs related to neuropathy, peripheral vascular disease, prevalence of the same and know the risk. Materials and methods: 165 patients were analyzed in four centers: Sanatorio Güemes (Diabetes and Endocrinology Service), PREDIGMA (Preventive Medicine Center, Posadas, Misiones), Central Hospital of San Isidro, Nexo Medical Center (Junín City) and Hospital Municipal of General Viamonte (Province of Buenos Aires). Results: it was found that 43.6% had some symptoms in the lower limbs and up to 57% had an alteration in the screening tests for diabetic neuropathy or peripheral arterial disease, with a higher prevalence the longer the evolution of DM. The most frequent signs found in the physical examination were: dry skin (71.5%), nail dystrophy (60.6%) or alteration of the foot pad (52.1%). The lost frequent comorbidities were: hypertension (74.5%) and dyslipidemia (73.3%). The median glycated hemoglobin was 7.40% (6.70-8.10), higher in people with a history of retinopathy (7.8%; p <0.01) and in patients who reported having cramps (7, 85 to 7.30; p = 0.03) or burning (8.0 vs 7.3; p <0.01). The percentage of patients with high-risk foot due to antecedents, inspection or screening for neuropathy or vascular disease represented from 40% in those with DM of less than five years of evolution to 86% in those who were older than 20 years. Conclusions: this high percentage of patients with foot at risk identified in this study suggests that, in addition to the correct physical examination, the attending physician requires the taking of behaviors, such as the indication of appropriate footwear or insoles, as well as a fluid referral to the orthotic technician, orthopedic surgeon, or physiatrist.

Risk factors associated with diabetic neuropathy in Mexican patients.

INTRODUCTION: Diabetic neuropathy (DN) is one of the most common complications of type 2 diabetes (T2D) and is a leading cause of lower limb amputation. The aim of the present study was to evaluate the risk factors contributing to DN in Mexican patients through the comparison of T2D patients with and without DN. MATERIALS AND METHODS: This cross-sectional study consisted of 509 subjects from Mexico who were classified as with DN and without DN. DN was assessed according to Douleur Neuropathique 4 questionnaire. Logistic regression analysis was performed to analyze risk factors contributing to DN. RESULTS: The prevalence of DN in the studied population was 28.3%. The risk factors associated with DN were T2D duration (odds ratio [OR]: 2.51; 95% confidence interval [CI] 1.36-4.65), glycemic exposure index (OR: 1.82; 95% CI 1.01-3.64), low- and high-density lipoprotein levels (OR: 1.53; 95% CI 1.02-2.31), metformin treatment (OR: 2.08; 95% CI 1.11-3.91), diabetic retinopathy (OR: 1.65; 95% CI 1.07-2.54), and smoking (OR: 1.51; 95% CI 1.00-2.26). CONCLUSIONS: Therefore, the early identification of risk factors for DN development in Mexican population would allow implementing personalized strategies to improve the overall T2D patients' quality of life and reduce healthcare costs in our country.

ANTECEDENTES: La neuropatía diabética (ND) es una de las complicaciones más comunes de la diabetes tipo 2 (DT2). ­. OBJETIVO: Investigar los factores de riesgo que contribuyen al desarrollo de ND en población mexicana con DT2, comparando pacientes diabéticos con y sin ND. MÉTODO: Estudio transversal con 509 pacientes mexicanos con DT2, clasificados en dos grupos, con y sin ND. La ND fue diagnosticada con el cuestionario DN4. La identificación de los factores de riesgo de ND se realizó mediante un análisis de regresión logística. RESULTADOS: La prevalencia de ND en la población de estudio fue del 28.3%. Los factores de riesgo asociados a ND fueron la duración de la DT2 (odds ratio [OR]: 2.51; intervalo de confianza del 95% [IC 95%]: 1.36-4.65), el índice glucémico (OR: 1.82; IC 95%: 1.01-3.64), las concentraciones bajas de colesterol unido a lipoproteínas de alta densidad (OR: 1.53; IC 95%: 1.02-2.31), el tratamiento con metformina (OR: 2.08; IC 95%: 1.11-3.91), la retinopatía diabética (OR: 1.65; IC 95%: 1.07-2.54) y el tabaquismo (OR: 1.51; IC 95%: 1.00-2.26). CONCLUSIONES: La identificación temprana de los factores de riesgo para el desarrollo de ND en población mexicana permitirá implementar estrategias personalizadas para mejorar la calidad de vida de los pacientes con DT2 y disminuir el gasto del sector salud originado por esta complicación.

Neuropathic pain screening for diabetes mellitus: a conceptual analysis / Rastreamento de dor neuropática para diabetes mellitus: uma análise conceitual

ABSTRACT BACKGROUND AND OBJECTIVES: The assessment and early diagnosis of neuropathic pain associated to Peripheral Diabetic Neuropathy has been a challenge in clinical practice, requiring the systematization of risk tracking through the identification of specific instruments to guide treatment. The objective of this study was to identify specific instruments for tracking neuropathic pain and Peripheral Diabetic Neuropathy in order to build a protocol. CONTENTS: Integrative review using the indexed databases Scielo, Cochrane and Pubmed between 2007 and 2020, identifying the most used validated instruments in high predictive value for tracking Peripheral Diabetic Neuropathy and neuropathic pain, building a specific protocol directing clinical treatment. 44 selected articles pointed out 14 different instruments for screening of Peripheral Diabetic Neuropathy and neuropathic pain, most prevalent being: the Screening Instrument for Assessment of Peripheral Diabetic Neuropathy (MNSI), Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) and Douleur Neuropathique (DN4) for clinical assessment of neuropathic pain and Brief Pain Inventory (BPI) for numerical pain assessment, highlighted by their predictive values above 80%. CONCLUSION: Such instruments enable the development of a neuropathic pain screening protocol that will assist in the early diagnosis of this complication in Diabetes, directing clinical and physiotherapeutic treatment.

Impact of sleep apnoea-hypopnoea syndrome on diabetic neuropathy. A systematic review. / Impacto del síndrome de apnea-hipopnea del sueño en la neuropatía diabética. Revisión sistemática.

INTRODUCTION: Diabetes mellitus and sleep apnoea-hypopnoea syndrome appear to be related, but it is not well defined whether there is an increased risk of peripheral neuropathy in patients with both diseases. For this reason, we conducted a systematic review. METHODS: Bibliographic search in 3 electronic databases using a predefined strategy and the PRISMA methodology. Only original studies (any type of design) published from 2000 onwards in English, French, Portuguese or Spanish were included. A study quality scale was established. RESULTS: Twelve articles were selected, of which six studied type 2 diabetic patients. The overall prevalence of sleep apnoea-hypopnoea syndrome was 43.7% (1,559/3,564 patients). Diabetic neuropathy was more frequent in patients with sleep apnoea-hypopnoea syndrome in nine studies, although significantly only in four (60% vs 27%, P<.001; 64.5% vs 36%, P=.03; 37% vs 23.4%, P<.02; 66.6% vs 0%, P=.007). In one study, diabetic neuropathy was more frequent in patients without sleep apnoea-hypopnoea syndrome (although not statistically significant) and in 2 no comparison was made between patients with/without sleep apnoea/hypopnoea syndrome. CONCLUSIONS: The observed results suggest a relationship between diabetes mellitus and sleep apnoea-hypopnoea syndrome in the occurrence of diabetic neuropathy.

El ataque de pie diabético es uno de los desenlaces más fatídicos para el paciente con diabetes, lo que demuestra la importancia del control en una enfermedad que avanza hasta presentar cambios macroscópicos importantes en el miembro inferior. Durante la progresión de la Diabetes, la enfermedad puede derivar en un aumento de la morbilidad e intervenciones invasivas y limitantes para el paciente, de ahí la importancia de la detección e intervención temprana y oportuna de la patología por parte del equipo médico. Estas recomendaciones van dirigida a médicos generales y especialistas en diversas ramas médicas, con el objetivo de enfatizar el cómo se debe realizar el abordaje integral del paciente con pie diabético. Abarcando la prevención, diagnóstico inicial, evaluación de la progresión de la patología, estratificación con las clasificaciones propuestas, y por último el tratamiento según el estadio en el que se encuentre el paciente. Esto con el fin de minimizar desenlaces, intervenciones y complicaciones derivadas de la progresión del pie diabetico. Hablamos de recomendaciones y no de guías debido a la ausencia en un gran número de oportunidades de evidencia científica debidamente estructurada (I y II). Tal vez lo más importante por recalcar en todas estas recomendaciones es recordarle al lector que en los casos de afectación de un pie diabético, siempre se debe tener en cuenta que el pie contralateral también ha estado sometido a la misma enfermedad durante el mismo tiempo y por lo tanto aunque no tenga síntomas se debe considerar igualmente enfermo y se debe examinar también.

Diabetic foot is one of the most fatal outcomes for patients with diabetes; the importance of control in a disease that progresses until presenting important macroscopic changes in the lower limb is absolutely relevant. Along diabetes progression, the disease can lead to increased morbidity and invasive and limiting interventions for the patient, hence the importance of early and timely detection and intervention of the pathology by the medical team. These recommendations are addressed to general practitioners and specialized faculty in various medical branches, emphasizing how a comprehensive approach to the patient with diabetic foot should be carried out. Covering prevention, initial diagnosis, evaluation of the progression of the pathology, stratification with the proposed classifications, and finally the treatment according to the stage in which the patients are, is actually well described herein in order to minimize unsatisfactory outcomes, interventions and complications derived from the progression of diabetic foot. We are talking about recommendations and not guidelines due to the absence in a large number of opportunities of properly structured scientific evidence (I and II). Perhaps, the most important thing to emphasize in all these recommendations is to remind the reader that in cases of treating a diabetic foot, it should always be kept in mind that the contralateral foot is not healthy because it has also been subjected to the same disease, for the same period of time and stressed equally as well. Therefore, even if the contralateral foot does not have symptoms, it should be considered equally ill and should be examined and treated likewise.

Resumen: La principal complicación crónica de la diabetes mellitus es la neuropatía, en particular la polineuropatía diabética. El objetivo de este estudio fue evaluar la prevalencia de polineuropatía y su asociación a factores de riesgo y complicaciones crónicas en una unidad de diabetes. En una población de 81 pacientes diabéticos, se encontró una prevalencia de polineuropatía de 34.6%. Es más frecuente y severa en la población de DM2, y se asoció con mayor tiempo de evolución de la enfermedad y complicaciones microangiopáticas. La polineuropatía sintomática predominó en el sexo femenino. Se concluye que la población diabética debe ser sometida a screening oportuno de polineuropatía.

Abstract: The main chronic complication of diabetes mellitus is neuropathy, in particular diabetic polyneuropathy. The objective of this study was to evaluate the prevalence of polyneuropathy and its association with risk factors and chronic complications in a diabetes unit. In a population of 81 diabetic patients, a polyneuropathy prevalence of 34.6% was found. It is more frequent and severe in the T2DM population, and was associated with longer disease progression and microangiopathic complications. Symptomatic polyneuropathy predominated in the female sex. It is concluded that the diabetic population should undergo timely screening for polyneuropathy.
