Association of blood groups/Rh and diabetes mellitus in Karachi city, Pakistan

Abstract The main purpose of this study was to find out a possible association between ABO blood groups or Rh and diabetes mellitus (DM) in the local population of eight (8) different towns of Karachi, Pakistan. For this purpose a survey was carried out in Karachi to have a practical observation of these towns during the period of 9 months from June 2019 to Feb. 2020. Out of eighteen (18) towns of Karachi, samples (N= 584) were collected from only eight (8) Towns of Karachi and gave a code-number to each town. Diabetic group sample was (n1=432) & pre-diabetes sample was (n2 =152). A standard Abbot Company Glucometer for Random Blood Sugar (RBS) and Fasting Blood Sugar (FBS) tests, standard blood anti sera were used for ABO/Rh blood type. Health assessment techniques were performed ethically by taking informed consent from all registered subjects. Finally data was analyzed by SPSS version 20.0. In our current study, the comparison of ABO blood groups frequencies between diabetic and pre-diabetic individuals were carried out. The percentage values of blood Group-B as given as: (32% in DM vs. 31% in pre-diabetics), followed by blood Group-O as: (18% in DM vs. 11% in pre-diabetics). Contrary to Group-B & O, blood Group-A and Group-AB were distribution percentage higher pre-diabetic as compared to DM patients, as given as: Group-A (32% in pre-diabetics vs. 26% in DM) & Group-AB (26% in pre-diabetics vs. 24% in diabetics patients). In addition, percentage distribution of Rh system was also calculated, in which Rh+ve Group was high and more common in DM patients as compared to pre-diabetics; numerically given as: Rh+ve Group (80% in DM vs. 72% in pre-diabetics). Different views and dimensions of the research topic were studied through literature support, some have found no any association and some established a positive association still some were not clear in making a solid conclusion. It is concluded that DM has a positive correlation with ABO blood groups, and people with Group-B have increased susceptibility to DM disease.

Resumo O objetivo principal deste estudo foi descobrir uma possível associação entre grupos sanguíneos ABO ou Rh e diabetes mellitus (DM) na população local de oito (8) diferentes cidades de Karachi, Paquistão. Para tanto, foi realizado um levantamento em Karachi para observação prática dessas cidades durante o período de 9 meses de junho de 2019 a fevereiro de 2020.De dezoito (18) cidades de Karachi, as amostras (N = 584) foram coletadas de apenas oito (8) cidades de Karachi e deram um número-código para cada cidade. A amostra do grupo de diabéticos foi (n1 = 432) e a amostra de pré-diabetes foi (n2 = 152). Um glicômetro padrão da Abbot Company para testes de açúcar no sangue aleatório (RBS) e açúcar no sangue em jejum (FBS), antissoros de sangue padrão foram usados para o tipo de sangue ABO / Rh. As técnicas de avaliação de saúde foram realizadas de forma ética, tomando o consentimento informado de todos os indivíduos registrados. Finalmente, os dados foram analisados pelo SPSS versão 20.0.No presente estudo, foi realizada a comparação das frequências dos grupos sanguíneos ABO entre diabéticos e pré-diabéticos. Os valores percentuais do sangue do Grupo-B são dados como: (32% em DM vs. 31% em pré-diabéticos), seguido pelo sangue do Grupo-O como: (18% em DM vs. 11% em pré-diabéticos). Ao contrário dos Grupos B e O, sangue do Grupo-A e Grupo-AB tiveram distribuição percentual maior de pré-diabéticos em comparação com pacientes com DM, dado como: Grupo-A (32% em pré-diabéticos vs. 26% em DM) e Grupo AB (26% em pré-diabéticos vs. 24% em pacientes diabéticos). Além disso, também foi calculada a distribuição percentual do sistema Rh, no qual o Grupo Rh + ve foi elevado e mais comum em pacientes com DM em comparação aos pré-diabéticos; dados numericamente como: Grupo Rh + ve (80% em DM vs. 72% em pré-diabéticos). Diferentes visões e dimensões do tema de pesquisa foram estudadas com o suporte da literatura, alguns não encontraram nenhuma associação e alguns estabeleceram uma associação positiva, embora alguns não estivessem claros em fazer uma conclusão sólida. Conclui-se que o DM tem correlação positiva com os grupos sanguíneos ABO, e as pessoas com o Grupo B têm maior suscetibilidade à doença DM.

Función biológica de AMPK- ß2 en músculo esquelético y su dinámica estructural después de la activación por SC4 / Biological role of AMPK- ß2 in skeletal muscle and its structural dynamics after activation by SC4

INTRODUCCIÓN: la Proteína Quinasa Activada por AMP (AMPK), es una enzima monitora y reguladora central del estado energético celular, por tanto, es responsable de la respuesta celular al suministro y demanda de energía. El AMP actúa como activador en condiciones de déficit energético, mientras que el ATP la inactiva cuando las condiciones energéticas son más favorables. Debido a su función central en el metabolismo, la AMPK surge como un blanco proteico prometedor para el tratamiento de diferentes enfermedades como la Diabetes Mellitus tipo 2 (DM2), Síndrome Metabólico (SM), Cáncer, entre otros. Existen múltiples isoformas de AMPK que se regulan y expresan diferencialmente en todo el organismo. La isoforma AMPK­ß2 se expresa casi exclusivamente en músculo esquelético y dado que este es el órgano primario para el almacenamiento y eliminación de Glucosa, AMPK­ß2 puede dirigir su homeostasis por una ruta independiente a la Insulina. La molécula activadora SC4 tiene una gran selectividad por AMPK­ß2 y debido a su función biológica, podría servir como modelo farmacológico para coadyuvar el tratamiento de enfermedades metabólicas. OBJETIVO: análisis de la dinámica molecular de activación de la AMPK­ß2. METODOLOGÍA: en el presente estudio, se emplean herramientas bioinformáticas como Chimera 1.15 y Phyton Molecular Viewer. RESULTADOS: el análisis in silico permitió comprender varios aspectos estructurales relacionados con la acción de SC4 sobre la estructura trimérica de la AMPK, los aminoácidos con los que interacciona y cómo su estructura química le otorga gran selectividad. También fue útil para en un futuro, ampliar los criterios de extracción, identificación y/o diseño de compuestos activos a partir de fuentes naturales, con propiedades funcionales similares o aún mejores a SC4, para así poder emplearlos con un enfoque terapéutico que beneficie a nuestra población.

INTRODUCTION: protein Kinase Activated by AMP (AMPK), is a monitor enzyme and a central regulator of the energetic cellular state, therefore, it is responsible for the cellular response to the supply and demand of energy. AMP acts as an activator in conditions of energy deficit, while ATP inactivates it when energy conditions are more favorable. Due to its central role in metabolism, AMPK appears as a promising protein target for the treatment of different diseases such as Diabetes Mellitus type 2 (DM2), Metabolic Syndrome (SM), and Cancer among others. There are multiple isoforms of AMPK that are regulated and differentially expressed throughout the body. The ß2-AMPK isoform is expressed almost exclusively in skeletal muscle and since this is the primary organ for Glucose disposal and storage, ß2-AMPK has an established role as a driver of insulin-independent Glucose clearance. The activator SC4 has a high selectivity for ß2-AMPK and due to its biological function; it could serve as a pharmacological model to aid the treatment of metabolic diseases. OBJETIVE: to analize the molecular dinamic of AMPK- ß2 activation. METHODOLOGY: in the present work we employed bioinformatics, Chimera 1.15 and Phyton Molecular Viewer. RESULTS: the in silico analysis allow us to understand many many structural features related to the action of SC4 on the trimeric structure of AMPK, the specific amino acids involved in the interaction and how its chemical structure gives it high selectivity. Thus, this structural analysis will be useful in order to broaden the criteria for extraction, identification and/or design of active compounds from natural sources, with similar or even better properties than SC4, to use them in a future, with a therapeutic approach that benefits our population.

Diabetes mellitus tipo 2 de inicio en paciente joven: implicancias en la población chilena / Young-onset type 2 diabetes mellitus: implications in the chilean population

La diabetes mellitus tipo 2 (DM2), habitualmente asociada a adultos en edad media y adulto mayor, ha presentado un aumento en su incidencia en pacientes menores de 40 años, lo que se conoce como DM2 de inicio en paciente joven. Varios estudios sugieren que este tipo de diabetes presenta no sólo un deterioro más rápido de las células beta-pancreáticas en comparación con la DM2 de inicio más tardío, sino que también un mayor riesgo de complicaciones que pacientes con DM Tipo1, lo que sugiere una variable independiente de los años de exposición a la enfermedad y por tanto, un fenotipo más agresivo. Por otra parte, hay evidencia que afirma que existen grupos poblacionales en mayor riesgo de desarrollar esta patología, particularmente ciertas etnias. En el presente trabajo se exponen los principales hallazgos de una reciente revisión del tema y se los compara con los datos nacionales disponibles. Dada la alta prevalencia de DM2 en la población chilena y la escasa cantidad de estudios epidemiológicos de calidad que permitan conocer nuestro panorama con mayor precisión, es que se destaca la importancia de estos últimos para poder tomar medidas de salud pública adecuadas.

Type 2 diabetes mellitus type 2 (T2DM), commonly associated with the middle to old aged adults group, has shown an increase in incidence in patients younger than 40 years old, which is known as young-onset type 2 diabetes mellitus. Several studies suggest that this type of diabetes not only exhibits a faster deterioration of the beta-pancreatic cells in comparison with type 1 diabetes mellitus patients, but also a greater risk of complications not regarding the time of exposure to the disease, therefore a more aggressive phenotype. Otherwise, there is evidence which asserts that some population groups are in mayor risk of developing this disease, especially certain ethnics. In this work it is exposed the main findings of a recent review of the subject and it is contrasted with available national data. Given the high prevalence of T2DM in the chilean population and the little amount of epidemiological high-quality studies that allows us to know our outlook with greater precision, it is highlighted the need for them in order to make adequate public health decisions.

Asociación del gen ELMO1 (snp rs1345365) con el desarrollo de diabetes mellitus tipo 2 en población mestiza Mexicana / Association of the ELMO1 gene (snp rs1345365) with development of type 2 diabetes mellitus in the Mexican mestizo population

El locus g.37190613 en 7p14.2-14.1 del gen ELMO1 presenta un polimorfismo el cual consiste en un cambio G>A(rs1345365). Esta variante, entre otras, de ELMO1, ha sido asociada con nefropatía diabética en diferentes poblaciones. En México son limitados los estudios de asociación de diabetes mellitus con genes candidatos. Por ello, el objetivo del presente trabajo fue determinar la asociación del SNP rs1345365 del gen ELMO1 con el desarrollo de diabetes mellitus tipo 2 (DM2). Para ello se analizaron 148 pacientes con DM2, 156 individuos sin diabetes pero con factores de riesgo cardiovascular y 269 personas sanas sin DM2. El polimorfismo se identificó por PASA (PCR AMPLIFICATION ALLELE SPECIFIC) y PAGE teñida con nitrato de plata. La asociación se estableció por diferentes modelos de epidemiología genética; el modelo dominante mostró una asociación positiva (p=0,0006) como factor protector y el para-dominante mostró al estado heterocigoto como factor de riesgo. En conclusión el estudio reveló la asociación del SNP rs1345365 del gen ELMO1 con DM2 en una población mestiza Mexicana.

The g.37190613 locus on 7p14.2-14.1 in the ELMO1 gene has a G>A polymorphism (SNP rs1345365) that has been associated with diabetic nephropathy in different populations. The genetic-association studies in type 2 diabetes mellitus (DM2) on the Mexican population are limited. The aim of this study was to estimate whether the polymorphism G>A of ELMO1 gene is associated with the development of DM2. We included 148 DM2 individuals, 156 individuals with cardiovascular risk factors without diabetes and 269 healthy proband without DM2. The polymorphism was identified by PCR amplification specific allele (PASA), PAGE and silver staining. The association was established by genetic epidemiological models; the dominant model showed a positive association (p=0.0006) as a protective factor, and the para-dominant model to heterozygous, as risk factor. In conclusion, this study revealed the association of the SNP rs1345365 of the ELMO1 gene in a Mexican population.

Efecto de la combinación fija de Vildagliptina/Metformina o Sitagliptina/Metformina sobre la lipemia postprandial en pacientes con diabetes tipo 2

Objetivo: evaluar el efecto de la combinación fija de vildagliptina o sitagliptina con metformina sobre la lipemia postprandial (PP) en pacientes con diabetes tipo 2 (DM2) previamente tratados solo con metformina. Métodos: cincuenta y siete pacientes con DM2 tratados con metformina y dieta, con valores de HbA1c entre 6,5-8,5% participaron en estudio aleatorizado, doble ciego de 8 semanas. Los participantes recibieron una carga oral de grasa antes y después de 8 semanas de la administración aleatorizada de combinación fija vildagliptina/metformina(grupo 1; n=29) o sitagliptina/metformina (grupo2; n = 28). Muestras de sangre se tomaron basalmente y a intervalos de 2 horas durante 8 horas después de la ingestión de la carga grasa. Resultados: la respuesta PP integrada de triglicéridos (AUC-TG) disminuyó en el 76% de los pacientes del grupo 1 y en el 64% del grupo 2. El perfil lipídico en ayunas no mostró cambios significativos post tratamiento. La glucosa en ayunas y 2h PP y la HbA1c disminuyeron significativamente en ambos grupos (p<0,01) acompañado de una disminución del IMC y la presión arterial (p<0,01). No se observaron efectos adversos. Conclusiones: además de mejorar el control glucémico, el tratamiento con combinación fija de vildagliptina/metformina o sitagliptina/metformina tiene un efecto beneficioso similar sobre la lipemia PP, lo cual es importante para mejorar el riesgo cardiometabólico de los pacientes con DM2.

Objective: to assess the effect of fixed combination of vildagiptin/metformin and sitagliptina/ metformin on postprandiallipemia (PP) in patients with type 2 diabetes mellitus (DM2). Methods: fifty-seven patients with DM2 previously treated with metformin and diet and HbA1c between 6,5-8,5% participated in a 8 weeks randomized, double blind study. An oral fat load was performed at baseline and 8 weeks after treatment with fixed combination of vildagliptin/metformin (grupo 1; n=29) or sitagliptin/metformin (group 2; n=28) twice a day. Blood samples were taken at baseline and at 2 hours interval during 8 hours after oral fat load. Results: integrated postprandial triglyceride response (AUC-TG) decreased in 76% of patients of group 1 and 64% of group 2. Fasting lipoprotein profile did not show significant changes post treatment. Both fasting and 2h postprandial glucose and HbA1c showed a significant decrease in both groups, in association with a decrease of body mass index and blood pressure (p<0,001). No adverse effects were observed. Conclusions: besides improving glucose control, fixed combination of vildagliptin/metformina or sitagliptina/metformin treatment has a beneficial effect postprandial lipemia which is important to improve the cardiometabolic risk of type 2 patients.

Ingesta de alimentos de origen animal versus origen vegetal y riesgo cardiovascular / Intake of animal versus vegetable food and cardiovascular risk

Cardiovascular mortality has been associated with changes in lifestyle and food habits. The occidental diet has been characterized by high intake of animal fat and meat, and it is associated whit increased risk of type 2 diabetes and high blood pressure, an increase in levels of markers of endothelial dysfunction, and presence of pro-thrombotic risk factors. We search the Pubmed database and other review references. Inclusion criteria were: papers published after 1999, randomized controled clinical studies, case-control studies, systematic reviews and methanalyses. Vegetarians groups show less cardiovascular morbidity and mortality than non-vegetarians. The evidence indicated that a decreasing intake of red meat, saturate fat, trans fat, and mainly processed meat, and an increase in the intake of whole grain cereals, fruits, vegetables and fish, are associated with a better overall cardiovascular health and survival.

El aumento de la mortalidad cardiovascular en el último tiempo está fuertemente asociado a cambios en los hábitos de alimentación. La dieta occidental caracterizada por una alta ingesta de alimentos de origen animal, presenta mayor riesgo de diabetes tipo 2 (DM 2), hipertensión arterial (HTA), aumento de marcadores de disfunción endotelial y factores protrombóticos. La búsqueda se realizó en la biblioteca online Pubmed y en referencias de otras revisiones. Los criterios de inclusión fueron: artículos de 1999 en adelante, ensayos clínicos aleatorizados-controlados, estudios caso-control, revisiones sistemáticas y meta análisis. En grupos con alto consumo de alimentos de origen vegetal se ha evidenciado una menor morbi-mortalidad cardiovascular, comparado con los grupos con alta ingesta de alimentos de origen animal. La evidencia apoya que la disminución en el consumo de carnes rojas, grasas saturadas y grasas trans, así como el aumento en el consumo de cereales integrales, frutas, vegetales y pescado, disminuye la morbi-mortalidad global y cardiovascular.

Insulinorresistencia e hígado graso no alcohólico, ¿existe relación causa-efecto entre ambas condiciones? / Insulin-resistance and non-alcoholic fatty liver, is there a cause-effect relationship between both conditions?

La insulinorresistencia y el síndrome de insulinorresistencia constituyen la causa primaria mas importante dentro de la etiopatogenia del hígado graso no alcohólico, conjuntamente con la obesidad y la diabetes mellitus tipo 2. La insulinorresistencia puede ser causa y a la vez consecuencia de la enfermedad hepática. La prevalencia del hígado graso no alcohólico documentada en trabajos realizados en países desarrollados es la siguiente: el hígado graso no alcohólico simple tiene una prevalencia de un 20 a 23 por ciento, aumentando en los pacientes con hipertransaminasemia persitente, en los que se puede observar una prevalencia entre 21 y 63 por ciento, y la prevalencia de esteatohepatitis oscila entre un 2 y un 3 por ciento de la población. Es bueno señalar que esta prevalencia va en aumento conjuntamente con el aumento de la prevalencia del síndrome de insulinorresistencia, la obesidad y la diabetes mellitus tipo 2. El hígado graso no alcohólico constituye la causa mas frecuente de hipertransaminasemia persistente, de hepatopatía crónica y de cirrosis hepßtica idiopática. La edad igual o superior a 40 años, la presencia de insulinorresistencia, de síndrome de insulinorresistencia, de obesidad y de diabetes mellitus tipo 2, ensombrecen el pronóstico de los pacientes con hígado graso no alcohólico, por lo que la presencia de estos factores antes mencionados son considerados factores de mal pronóstico en el paciente con hígado graso no alcohólico(AU)

Insulin resistance and the insulin resistance syndrome are the more significant main cause in pathogeny of non-alcoholic fatty liver, together with obesity and type 2 diabetes mellitus. Insulin resistance may be the cause and the consequence of hepatic disease. Prevalence of non-alcoholic fatty liver documented in papers performed in developing countries is at follow: from a 20 percent to 23 percent, increase in patients presenting with persistent high level of transaminase, in which it is possible to observe a prevalence between 21 percent and 63 percent, and prevalence of steatohepatitis fluctuates between 2 percent and 3 percent of population. We must to mark that this prevalence is increasing together with the prevalence increase of insulin resistance syndrome, obesity, and type 2 diabetes mellitus. The non-alcohol fatty liver is the more frequent cause of a persistent high level of transaminase, of chronic liver disease, and of idiopathic liver cirrhosis. An age similar or higher than 40 years, presence of insulin resistance, insulin resistance syndrome, obesity, and type 2 diabetes mellitus darken the prognosis of patients presenting with non-alcoholic fatty liver, so the presence of above mentioned factors is considered as a poor prognosis factors in patient presenting non-alcoholic fatty liver(AU)

Association of polymorphisms at the ADIPOR1 regulatory region with type 2 diabetes and body mass index in a Brazilian population with European or African ancestry

Association studies between ADIPOR1 genetic variants and predisposition to type 2 diabetes (DM2) have provided contradictory results. We determined if two single nucleotide polymorphisms (SNP c.-8503G>A and SNP c.10225C>G) in regulatory regions of ADIPOR1 in 567 Brazilian individuals of European (EA; N = 443) or African (AfA; N = 124) ancestry from rural (quilombo remnants; N = 439) and urban (N = 567) areas. We detected a significant effect of ethnicity on the distribution of the allelic frequencies of both SNPs in these populations (EA: -8503A = 0.27; AfA: -8503A = 0.16; P = 0.001 and EA: 10225G = 0.35; AfA: 10225G = 0.51; P < 0.001). Neither of the polymorphisms were associated with DM2 in the case-control study in EA (SNP c.-8503G>A: DM2 group -8503A = 0.26; control group -8503A = 0.30; P = 0.14/SNP 10225C>G: DM2 group 10225G = 0.37; control group 10225G = 0.32; P = 0.40) and AfA populations (SNP c.-8503G>A: DM2 group -8503A = 0.16; control group -8503A = 0.15; P = 0.34/SNP 10225C>G: DM2 group 10225G = 0.51; control group 10225G = 0.52; P = 0.50). Similarly, none of the polymorphisms were associated with metabolic/anthropometric risk factors for DM2 in any of the three populations, except for HDL cholesterol, which was significantly higher in AfA heterozygotes (GC = 53.75 ± 17.26 mg/dL) than in homozygotes. We conclude that ADIPOR1 polymorphisms are unlikely to be major risk factors for DM2 or for metabolic/anthropometric measurements that represent risk factors for DM2 in populations of European and African ancestries.
