Introducción: La diabetes mellitus produce complicaciones, dentro de las cuales se describen la neuropatía diabética y la angiopatía diabética, que en presencia de estas puede llegarse a un cuadro de pie diabético sin dejar de mencionar la pérdida visual por retinopatía diabética. Objetivo: Determinar la correlación existente entre la aparición de pie diabético y la presencia o no de la retinopatía diabética en pacientes del Hospital Provincial "María Eugenia Neto", Zaire, República de Angola, en el período comprendido entre septiembre de 2020 a septiembre de 2022. Método: Se realizó un estudio descriptivo en 181 pacientes de la consulta de pie diabético del hospital antes dicho, donde se describieron variables, tales como: edad, sexo, enfermedades crónicas asociadas, presencia o no de retinopatía diabética, úlceras en miembros inferiores, amputación en miembros inferiores y años con diabetes. Se realizaron pruebas de correlación bivariable, se analizó el coeficiente de correlación de Pearson. Resultados: El promedio de edad fue de 59,3 años, predominó el grupo etario de más de 70 años (28,2 %) y el sexo femenino (57,5 %). Presentaron amputaciones previas un 41,8 % y úlceras un 40,1 %. Sin tratamiento estable el 65,19 %, correlación estadísticamente fuerte y significativa entre pie diabético y la retinopatía diabética. Conclusiones: Se evidencia una fuerte y significativa relación existente entre los pacientes portadores de pie diabético, los cuales pueden padecer determinado grado de retinopatía diabética, más frecuentes en el sexo femenino después de la sexta década de la vida, con los cuales presentan mayor tiempo de evolución de su enfermedad.

Introduction: Diabetes mellitus leads to many associated complications, including diabetic neuropathy and diabetic angiopathy, both with a high incidence in the onset diabetic foot and including also the diabetic retinopathy disease cause of blindness. Objective: Determine if there is any correlation between the onset diabetes foot and whether or not diabetic retinopathy present in patients treated at the Hospital Provincial, María Eugenia Neto, Zaire, Republic of Angola, from September 2020 to September 2020. Method: A descriptive study was carried out in 181 patients treated in the diabetic foot department of the aforementioned hospital; variables described were as follow: age, sex, associated chronic diseases, presence or absence of diabetic retinopathy, lower limb ulcers, limb amputation and years with diabetes. Bivariate correlation tests were performed, and the Pearson´s correlation coefficient was analyzed. Results: The average age was 59.3 years, the age group over 70 years (28.2%) and the female sex (57.5%) predominated. The 41.8% of patients presented previous amputations and 40.1% had ulcers. The 65.19% of patients had irregular treatment patterns, statistically strong and significant correlation between diabetic foot and diabetic retinopathy. Conclusions: There is evidence of a strong and significant relationship between patients with diabetic foot, who may suffer from a certain degree of diabetic retinopathy, more frequent in females after their sixth decade of life that cause a longer evolution of his disease.

Maduración pulmonar fetal en diabetes mellitus pregestacional y complicaciones crónicas / Fetal lung maturation in pregestational diabetes mellitus and chronic complications

Las pacientes embarazadas con diabetes mellitus (DM) pregestacional y complicaciones micro y macroangiopáticas tienen mayor riesgo de empeoramiento de las mismas y de presentar otros trastornos asociados al embarazo. La progresión de la retinopatía diabética ocurre durante el embarazo y el posparto. La nefropatía se asocia con un mayor riesgo de preeclampsia, parto prematuro, restricción del crecimiento fetal y mortalidad perinatal. Cuando hay enfermedad de arterias coronarias o gastroparesia se observa un aumento de la morbilidad materna y fetal. El parto prematuro es una condición prevalente en pacientes con DM. La maduración pulmonar fetal con corticosteroides fue extensamente estudiada, con numerosas pruebas controladas, hasta convertirse en una de las más importantes terapias prenatales basadas en evidencias para reducir la mortalidad perinatal y el síndrome de dificultad respiratoria, la hemorragia intraventricular y la enterocolitis necrosante en los niños prematuros. Sin embargo, en dicha evidencia no se han incluido a embarazadas con DM, por lo cual no se conocen resultados perinatales en este grupo de pacientes.

Pregnant patients with pregestational diabetes mellitus (DM) and micro and macroangiopathic complications have a higher risk of their worsening and of presenting other pregnancyassociated disorders. The progression of diabetic retinopathy occurs during pregnancy and postpartum. Nephropathy is associated with an increased risk of preeclampsia, preterm delivery, fetal growth restriction, and perinatal mortality. When there is coronary artery disease or gastroparesis, an increase in maternal and fetal morbidity is observed Preterm delivery is a prevalent condition in diabetic patients. Corticosteroid fetal lung maturation has been extensively studied, with numerous controlled trials, to become one of the most important evidence-based prenatal therapies to reduce perinatal mortality and decrease respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis, in premature infants. Nevertheless, this evidence did not include patients with DM, for this reason perinatal results are not known in this group of patients.

Resultados: Se observó predominio de los diabéticos tipo 2 respecto a los tipo 1 en una razón 11:1, con una media de 16,3 años de evolución de la diabetes. La mitad de los pacientes tenían retinopatía diabética no proliferativa, con predominio de la forma leve, en el examen realizado antes del tratamiento con Heberprot-P. Solo un paciente anciano con otras comorbilidades, desarrolló una retinopatía diabética proliferativa, luego de un examen previo en que se observó retinopatía diabética no proliferativa y edema macular diabético. Conclusiones: La aparición o progresión de retinopatía diabética es infrecuente en pacientes complicados con úlcera del pie diabético tratados con Heberprot-P, hasta cinco meses después de tratamiento(AU)

Introduction: The prevalence of diabetes gradually increases worldwide and with it, the risk of microvascular complications such as diabetic retinopathy. The risk of blindness is reduced with stable metabolic control, early diagnosis and adequate treatment. Objective: To compare the result of the ophthalmological examination performed before starting treatment with Heberprot-P, with that performed five months after initiation, at different doses. Methods: A retrospective observational study was conducted in 77 patients included in four clinical trials of Heberprot-P. Analysis of the ophthalmological examination variables before and after treatment, type of diabetes and years of evolution were performed. Results: Prevalence of type 2 diabetics was observed with respect to type 1 in an 11: 1 ratio, with an average of 16.3 years of diabetes evolution. Half of the patients had nonproliferative diabetic retinopathy, predominantly of the mild form, in the examination performed before treatment with Heberprot-P. Only one elderly patient with other comorbidities developed a proliferative diabetic retinopathy, after a previous examination in which non-proliferative diabetic retinopathy and diabetic macular edema were observed. Conclusions: The appearance or progression of diabetic retinopathy is uncommon in complicated patients with diabetic foot ulcer treated with Heberprot-P, up to five months after treatment(AU)

Research Progress of Yiqi Huoxue Prescription in Treatment of Diabetic Angiopathy / 中国实验方剂学杂志

Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia. Its main complications of diabetes, such as diabetic angiopathy, have seriously affected the quality of life for patients, and have become an important cause of death and disability. The underlying pathological changes include macrovascular lesions and microvascular lesions. Diabetic macrovascular lesions mainly involve thoracic aorta, coronary artery, carotid artery, cerebral artery and peripheral blood vessels, etc., and the common clinical diseases include coronary heart disease, stroke, peripheral neuropathy, lower extremity arteriosclerosis, etc. Diabetic microvascular lesions mainly involve the heart, brain, kidney and other microvessels. Nowadays, various new oral hypoglycemic agents and insulin have emerged in the society and are widely used in clinical practice. However, traditional Chinese medicines(TCMs) have stable curative effect, less side effect, and can improve glucose metabolism, lipid metabolism, insulin resistance, oxidative stress, expression of inflammatory cytokines, vascular endothelial injury, microcirculation disorders, balance of fibrinolysis system and blood coagulation system, and improve the syndromes of TCMs, etc. They have been widely recognized and applied in the prevention and treatment of diabetic angiopathy. A profound understanding on the etiology, pathogenesis and treatment of diabetic angiopathy has been formed in Chinese medicine. Therefore, in this paper, we would summarizes the understanding on Chinese medicine for diabetic angiopathy and the mechanism of Yiqi Huoxue prescription in the treatment of diabetic angiopathy in the past three years.

Factores de riesgo asociados al pie diabético

Introducción: El pie diabético representa una de las causas de mayor morbilidad e incapacidad en las personas con Diabetes Mellitus. Esta población abarca hasta el 70% de las amputaciones, en su mayoría desencadenada por la infección. La vasculopatía periférica, la neuropatía periférica asociadas al control metabólico juegan un rol importante en su génesis. El conocimiento de los mismos en la atención primaria asociadas a las medidas de prevención colaborarán en la disminución de este flagelo que aqueja a millones en la actualidad. Objetivos: Determinar los factores de riesgo asociados a las lesiones del pie diabético. Describir las características demográficas y clínicas de los pacientes con lesiones del pie diabético. Material y métodos: estudio de casos y controles. No probabilístico, de casos consecutivos. Se incluyeron pacientes adultos internados en el Departamento de Medicina Interna durante el 2015, diabéticos, con y sin lesiones en pie, sin amputaciones previas e independientes del tratamiento farmacológico. Resultados: se incluyeron 86 sujetos, de los cuales 59% de los casos presentaron onicomicosis, el 57% neuropatía, el 67% vasculopatía, 45% algún tipo de deformidad y un 63% utilizaban calzados inadecuados. Conclusiones: La onicomicosis representó un factor de riesgo significativo para el desarrollo del pie diabético (p=0,02). En lo que respecta a la vasculopatía, la neuropatía y el control glicémico no se pudo establecer un riesgo significativo.

Introduction: The diabetic foot is one of the main causes of higher morbidity and disability in people with Diabetes Mellitus. This population comprises up to 70% of amputations, mostly triggered by infections. The peripheral vascular disease and the peripheral neuropathy associated with metabolic control play an important role in its genesis. The knowledge about them associated with prevention measures in primary care contribute to reduce this scourge that currently afflicts millions. Objectives: To determine risk factors associated with diabetic food lesions and to describe the demographic and clinical characteristics of patients with diabetic foot lesions. Material and methods: Case-control study with non-probabilistic consecutive sampling. Adult diabetic patients with and without foot lesions, without previous amputations, independent of pharmacological treatment and admitted into the Department of Internal Medicine during 2015 were included. Results: 86 subjects were included, 59% of the cases had onychomycosis, 57% neuropathy, 67% vasculopathy, 45% some deformity and 63% used inadequate footwear. Conclusions: Onychomycosis represented a significant risk factor for the development of diabetic foot (p = 0.02). Concerning vasculopathy, neuropathy and glycemic control, a significant risk could not be established.

Impact of subclinical hypothyroidism on macro-vascular complications in elderly type 2 diabetic patients / 中华老年医学杂志

Objective To investigate the impact of subclinical hypothyroidism (SCH) on macrovascular complications in elderly type 2 diabetic patients.Methods A total of 1170 hospitalized elderly patients with type 2 diabetes mellitus were enrolled in the study through systematic sampling and underwent testing for blood biochemical indicators, thyroid function and C peptide.Parameters for macro-vascular complications, including the ankle/brachial index (ABI), transcranial Doppler vascular ultrasound (TCD), electrocardiogram (ECG), ejection fraction (EF), history of coronary heart disease, and hypertension grading were also monitored.Results All the subjects were divided into two groups based on the thyroid stimulating hormone (TSH) level: the euthyroid group (4 mU/L≥TSH＞0.4 mU/L) and the SCH group (TSH＞4 mU/L), and the latter was further sub-grouped into the mild SCH group (10 mU/L≥TSH＞4 mU/L) and the severe SCH group (TSH＞10 mU/L).ABI was significantly decreased in SCH (R/L: 0.86/0.92, P＜0.01).Levels of basal C-peptide (CP0) and post glucose-challenge C-peptide (CP1-3) were higher in the SCH group than in the euthyroid group [(2.16±0.93)pg/L vs.(1.56±1.05)pg/L, (0.53±0.25)pg/L v, (0.38±0.37),(0.72±0.23) pg/L vs.(0.56 ±0.32) pg/L, (6.21± 2.69) pg/L vs.(4.46 ± 2.62) pg/L,respectively, P＜0.01 for all].EF was higher in the SCH group than in the euthyroid group[(70.87± 6.66)％ vs.(65.10 ± 8.08％), P＜ 0.01].There were no significant differences in other biochemical indicators, ECG, TCD, history of coronary heart disease, hypertension grading and intervention treatment (P＞0.05 for all).Conclusions Lower extremity atherosclerotic disease has a higher incidence in elderly type 2 diabetic patients with SCH and occurs earlier than other macrovascular complications.Elevated TSH levels and insulin resistance may be the major causes.

Effect of Antiplatelets in Diabetic Peripheral Vasculopathy: Comparison by Ankle-Brachial Index and Peak Wave Velocity / 대한족부족관절학회지

PURPOSE: The purpose of this study is to confirm the effect of antiplatelet drugs in diabetic peripheral vasculopathy in diabetic foot patients. MATERIALS AND METHODS: We designed a retrospective study in diabetic foot patients with diabetic peripheral vasculopathy. From October 2007 to December 2013, 278 cases in 139 patients who took antiplatelet drugs over at least a six-month period were included in this study. We categorized these patients according to the type of drug used. The efficacy of antiplatelet drugs was evaluated using anklebrachial index (ABI) and pulse wave velocity (PWV). RESULTS: Only the aspirin group showed a statistically significant increase of ABI after antiplatelet therapy (1.10+/-0.12 to 1.12+/-0.11). In addition, only the cilostazol group showed a statistically significant decrease of PWV after antiplatelet therapy (1,701.20+/-396.56 to 1,627.42+/-324.98). CONCLUSION: Aspirin and cilostazol may be used in treatment of diabetic peripheral vasculopathy, whereas dual antiplatelet therapy with aspirin and clopidogrel has no specific benefits in diabetic peripheral vasculopathy.

The correlation between MCP-1 and cardiovascular complication of diabetes / 中国医师杂志

Objective To explore the significance and correlation between MCP-1 and cardiovascular complication of diabetes. Methods 65 patients with diabetes and 64 patents with IGT and 60 healthy persons as control group are chosen from a population of 1231residents at Jiangnan community in Guangzhou city. Ultrasonic inspection of carotid artery was applied to the intimae media thickness (IMT),and the levels of-MCP-1 were detected by Elisa. Result There was significant difference in the levels of MCP-1 among the normal control group, IGT group and DM group (P=0.000).The levels of MCP-1 in IGT complicated with AS patients were significantly higher than that in IGT alone patients. The levels of MCP-1 in DM complicated with AS patients were significantly higher than that in DM alone patients. The levels of MCP-1 were positively correlated with IMT in these patients. A forward LR Logistic regression analysis showed that IMT was a dependent variable, gender, MCP-1 and age are independently correlated with IMT. Conclusion MCP-1 is correlated with diabetes and its cardiovascular complication and it may be served as the target of therapy.
