Combination therapy of curcumin and alendronate modulates bone turnover markers and enhances bone mineral density in postmenopausal women with osteoporosis

ABSTRACT Objective: This study evaluated the effects of combination therapy of curcumin and alendronate on BMD and bone turnover markers in postmenopausal women with osteoporosis. Subjects and methods: In a randomized, double-blind trial study, 60 postmenopausal women were divided into three groups: control, alendronate, and alendronate + curcumin. Each group included 20 patients. Total body, total hip, lumbar spine and femoral neck BMDs were measured by dual-energy X-ray absorptiometry (DXA) at baseline and after 12 months of therapy. Bone turnover markers such as bone-specific alkaline phosphatase (BALP), osteocalcin and C-terminal cross-linking telopeptide of type I collagen (CTx) were measured at the outset and 6 months later. Results: Patients in the control group suffered a significant decrease in BMD and increased bone turnover markers at the end of study. The group treated with only alendronate showed significantly decreased levels of BALP and CTx and increased levels of osteocalcin compared to the control group. The alendronate group also showed significant increases in the total body, total hip, lumbar spine and femoral neck BMDs at the end of study compared to the control group. In the curcumin + alendronate group, BALP and CTx levels decreased and osteocalcin levels increased significantly at the end of study compared to the control and alendronate groups. BMD indexes also increased in four areas significantly at the end of study compared to the control and alendronate groups. Conclusion: The combination of curcumin and alendronate has beneficial effects on BMD and bone turnover markers among postmenopausal women with osteoporosis. Arch Endocrinol Metab. 2018;62(4):438-45

Fluxo mediado pela dilatação e espessura da íntima-média da carótida em pacientes com gastrite crônica associada com infecção por Helicobacter pylori / Flow mediated dilation and carotid intima media thickness in patients with chronic gastritis associated with helicobacter pylori infection

ABSTRACT BACKGROUND: Endothelial dysfunction is one of the early stages of vascular diseases. OBJECTIVE: The aim of this study was to investigate the endothelial dysfunction markers in patients with chronic gastritis associated with Helicobacter pylori (H. pylori) infection. METHODS: By a cross sectional study, basic and clinical information of 120 participants (40 patients with positive H. pylori infection, 40 patients with negative H. pylori infection and 40 healthy people) were analyzed. Carotid intima media thickness and flow-mediated dilation levels were measured in all patients and controls. Soluble vascular cell adhesion molecule-1 (sVCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were measured with Elisa for all subjects. IgG level was assessed in chronic gastritis patients. RESULTS: The flow-mediated dilation level in patients with positive H. pylori infection (0.17%±0.09) was significantly lower than those with negative H. pylori infection (0.21% ±0.10, P<0.05) and compared to the control group (0.27% ±0.11, P<0.05). Carotid intima media thickness level in patients with positive H. pylori infection (0.58±0.13 mm) was significantly higher than those with negative H. pylori infection (0.48±0.32 mm, P<0.05) and compared to the control group (0.36±0.44mm, P<0.05). The mean level of sICAM-1 in positive H. pylori infection group (352.16±7.54 pg/mL) was higher than negative H. pylori infection group (332.64±8.75 pg/mL =0.75) and compared to the control group (236.32±12.43 pg/mL, P<0.05). A direct relationship was revealed between flow-mediated dilation and carotid intima media thickness changes and between sICAM-1 and sVCAM-1 associated with the level of H. pylori IgG in chronic gastritis. CONCLUSION: The levels of flow-mediated dilation, carotid intima media thickness and sICAM-1 were higher among patients with positive H. pylori infection. Patients with chronic gastritis associated with H. pylori infection are at risk of endothelial dysfunction due to flow-mediated dilation and carotid intima media thickness abnormalities and increased level of sICAM-1 and sVCAM-1.

RESUMO CONTEXTO: A disfunção endotelial é um dos estágios iniciais de doenças vasculares. OBJETIVO: O objetivo deste estudo foi investigar os marcadores de disfunção endotelial em pacientes com gastrite crônica associada com infecção por Helicobacter pylori (H. pylori). MÉTODOS: Através de estudo cruzado seccional, foram analisadas informações básicas e clínicas de 120 participantes (40 pacientes com infecção pelo H. pylori, 40 pacientes sem infecção pelo H. pylori e 40 pessoas saudáveis). A espessura da camada íntima-média da carótida e níveis de dilatação mediada por fluxo foram medidos em todos os pacientes e controles. A adesão da molécula-1 solúvel (sVCAM-1) à célula vascular e da molécula de adesão intercelular-1 (ICAM-1) foram medidas pelo método Elisa para todas os indivíduos. O nível de H. pylori IgG foi avaliado em pacientes de gastrite crônica. RESULTADOS: O nível de dilatação mediada por fluxo em pacientes com infecção positiva pelo H. pylori foi significativamente menor do que em aqueles com infecção negativa (0,17% ±0, 09) X (0,21% ±0,10) P<0,05 e em relação ao grupo controle (0,27% ±0,11) P<0,05). O nível da espessura da íntima-média da carótida em pacientes com infecção positiva pelo H. pylori foi significativamente maior (0,58±0,13 mm) do que aqueles com negativa (0,48±0,32 mm) P<0,05) e em relação ao grupo controle (0,36±0,44 mm) P<0,05). O nível médio de sICAM-1 grupo de infecção H. pylori positiva (352,16±7,54 pg/mL) foi maior do que o grupo de infecção negativa (332,64±8,75 pg/mL = 0,75) e em relação ao grupo controle (236,32±12,43 pg/mL) P<0,05). Revelou-se uma relação direta entre a dilatação mediada por fluxo e alterações da espessura da íntima-média da carótida e sICAM-1 e sVCAM-1, associada com o nível de H. pylori IgG em gastrite crônica. CONCLUSÃO: Os níveis de dilatação mediada por fluxo, da espessura da íntima-média da carótida e sICAM-1 foram maiores entre os pacientes com infecção positiva pelo H. pylori. Pacientes com gastrite crônica associada a infecção por H. pylori correm o risco de disfunção endotelial, devido à dilatação mediada por fluxo e anormalidades da espessura da íntima-média da carótida e aumento do nível de sICAM-1 e sVCAM-1.

Cúrcuma em combinação com os regimes de terapia tríplice melhora o estresse oxidativo e as alterações histopatológicas em gastrite crônica associada à infecçäo por Helicobacter pylori / Curcumin in combination with triple therapy regimes ameliorates oxidative stress and histopathologic changes in chronic gastritis-associated helicobacter pylori infection

ABSTRACT BACKGROUND Helicobacter pylori (H. pylori) gastric infection is a main cause of inflammatory changes and gastric cancers. OBJECTIVE The aim of this study was finding the effects of curcumin on oxidative stress and histological changes in chronic gastritis associated with H. pylori. METHODS In a randomized clinical trial, patients were divided into two groups: a standard triple therapy group and triple therapy with curcumin group. Endoscopic and histological examinations were measured for all patients before and after 8 weeks. RESULTS Triple therapy with curcumin treatment group significantly decreased malondialdehyde markers, glutathione peroxides and increased total antioxidant capacity of the gastric mucosa at the end of study compared to baseline and triple regimen groups. In addition, the oxidative damage to DNA was significantly decreased in triple therapy with curcumin group at the end of study compared to baseline and compared to triple therapy (P<0.05 for both). Triple therapy group in combination with Curcumin significantly decreased all active, chronic and endoscopic inflammation scores of patients compared to the baseline and triple therapy group (P<0.05 for both). The eradication rate by triple therapy + curcumin was significantly increased compared to triple therapy alone (P<0.05). CONCLUSION Curcumin can be a useful supplement to improve chronic inflammation and prevention of carcinogenic changes in patients with chronic gastritis associated by H. pylori.

RESUMO CONTEXTO A infecção gástrica pelo Helicobacter pylori (H. pylori) é principal causa de alterações inflamatórias e de câncer gástrico. OBJETIVO O objetivo deste estudo foi encontrar os efeitos da cúrcuma no estresse oxidativo e as alterações histológicas na gastrite crônica associada ao H. pylori. MÉTODOS Em um estudo randomizado clínico experimental, pacientes foram divididos em dois grupos: um grupo de terapia tríplice padrão e outro com terapia tríplice com e cúrcuma. Exames endoscópicos e histológicos foram analisados para todos os pacientes antes e depois de 8 semanas de tratamento. RESULTADOS A terapia tríplice com grupo de tratamento de cúrcuma diminuiu significativamente os marcadores de malondialdeído, de peróxidos de glutationa, com aumento da capacidade antioxidante total da mucosa gástrica ao final do estudo em comparação com grupos de regime basal e tríplice. Além disso, o dano oxidativo ao DNA diminuiu significativamente em terapia tríplice com grupo de cúrcuma no final do estudo em comparação com a linha de base e comparado à terapia tríplice (P<0,05 para ambos). No grupo de terapia tríplice em combinação com cúrcuma houve diminuição significativa de todas os escores ativos de inflamação crônica e endoscópica dos pacientes em relação ao grupo de terapia de base e tríplice (P<0,05 para ambos). A taxa de erradicação por terapia tríplice + cúrcuma aumentou significativamente em relação à terapia tríplice isolada (P<0,05). CONCLUSÃO A cúrcuma pode ser um complemento útil para melhorar a inflamação crônica e prevenção de alterações cancerígenas em pacientes com gastrite crônica associada ao H.pylori.

Minimally invasive surgical interventions in the treatment of primary persistent hyperinsulinemic hypoglycemia of infancy

Hyperinsulinemia, diagnosed by laboratory tests, should be diagnosed and treated as soon as possible to prevent fatal complications such as neurological damage. Patients who are resistant to medical therapy should be treated surgically. Minimally invasive surgery, a newly developed approach, is a good choice among surgical procedures to avoid unnecessary extensive pancreatectomy. Here, a 12-year-old boy is presented with diagnosis of hyperinsulinemic hypoglycemia who had recurrent attacks of hypoglycemia and seizures from infancy. Because of his unresponsiveness to medical therapy and his family’s preference, he underwent laparoscopic pancreatectomy to reduce morbidity and hospital stay. Two years postsurgical follow-up revealed a normo-glycemic state.

Effects of anthropometric factors on foot size in normal preschool children of Iran / Efectos de los factores antropométricos sobre el tamaño del pie en niños preescolares normales de Irán

The growth pattern of children is affected by anthropometric dimensions. This study was aimed to investigate anthropometric factors related to growth of preschool children of a sample population in Iran. This study was performed in year 2011 on 1320 of 4­7 years old preschool children in Arak. To classify, body mass index (BMI), height and weight were recorded. The four contact points (head, back, buttocks, and heels) were maintained against the spine of the stadiometer during measurement. The head was positioned in the Frankfurt plane, and the sliding bar was lowered the crown of the head. Height was measured and recorded by the researchers. A pair of manual calibrated Seca scales was used to measure body mass in kilograms. The participants were least dressed in the uniform. We have classified BMI to four groups as group1, BMI with 10.75­15 and group 2, 3, 4 with 15.1­17 and 17.1­20, 20.1­22.5, respectively. Foot length was recorded as the distance from the posterior aspect of the heel to the most distal aspect of the longest toe. Foot length was measured with subjects standing upright using a foot board, a plastic device with calibrated lineation (in centimeters and millimeters). Analysis showed that sex neither affect on BMI nor foot measurements. The present findings contribute to the understanding of the effect of body mass on the structural development of the pediatric foot and musculoskeletal system. Excessive body mass seems to lead to increased foot length and width.

El patrón de crecimiento de los niños se ve afectado por las dimensiones antropométricas. El objetivo fue investigar los factores antropométricos relacionados con el crecimiento de los niños en edad preescolar de una muestra poblacional de Irán. Este estudio se realizó en el año 2011 en 1320 niños, de 4-7 años, de edad preescolar de Arak. Para clasificar el índice de masa corporal (IMC), se registraron la altura y el peso. Los cuatro puntos de contacto (cabeza, espalda, glúteos y talones) se mantuvieron contra la columna del estadiómetro durante la medición. La cabeza fue colocada en el plano de Frankfurt, y la barra de deslizamiento se redujo al nivel de la corona de la cabeza. Los investigadores midieron y registraron la altura. Se utilizaronn par de escalas manuales Seca calibradas para medir la masa corporal en kilogramos. Los participantes fueron vestidos con el uniforme escolar. Se clasificó el IMC en cuatro grupos: grupo 1 entre 10,75­15, grupo 2 entre 15,1­17, grupo 3 entre 17,1­20 y grupo 4 entre 20,1­22,5. La longitud del pie se definió como la distancia existente desde la cara posterior del talón hasta la porción más distal del dedo más largo. La longitud de pie se midió con los sujetos en posición de pie utilizando una tabla de pie, dispositivo de plástico con la alineación calibrada (en centímetros y milímetros). El análisis mostró que el sexo no influye en el índice de masa corporal ni las medidas del pie. Los presentes hallazgos contribuyen a la comprensión de los efectos de la masa corporal en el desarrollo estructural del pie y el sistema músculo-esquelético pediátrico. La masa corporal excesiva parece conducir a un aumento de la longitud y ancho del pie.
