ABSTRACT

Resumen Introducción: Actualmente la vitamina D ha ganado importancia, por ser considerada una hormona y porque sus bajos niveles están asociados con diferentes patologías, especialmente alteraciones de la masa ósea. Objetivo: Determinar la prevalencia de bajos niveles de vitamina D en pacientes adultos con osteopenia y osteoporosis, atendidos en consulta externa de endocrinología en Popayán Cauca. Materiales y métodos: Estudio descriptivo y retrospectivo que incluyó pacientes con diagnóstico de osteopenia y osteoporosis realizado por densitometría ósea entre los años 2013 y 2016, que tenían reporte de niveles de vitamina D obtenidos por cualquier método. Se describieron características sociodemográficas, resultados de densitometría ósea, niveles vitamina D, hormona paratiroidea y calcio iónico. Resultados: Se incluyeron 300 pacientes con diagnóstico de osteopenia y osteoporosis de los cuales 211 tenían bajos niveles de vitamina D, para una prevalencia del 71,3%, el nivel promedio de 25 hidroxivitamina D fue de 24,35ng/ml. Conclusiones: La alta prevalencia de bajos niveles de vitamina D en pacientes con osteopenia y osteoporosis hace indispensable la medición de 25 hidroxivitamina D en esta población, esto con el fin de realizar una intervención terapéutica apropiada.


Abstract Introduction: Vitamin D has gained interest because it is a hormone whose low levels are associated with different pathologies such as bone mass disorders. Objective: To determine the prevalence of low levels of vitamin D in adult patients with osteopenia and osteoporosis who received care at an outpatient endocrinology clinic in Popayan, Cauca. Materials and methods: A retrospective and descriptive study that included patients diagnosed with osteopenia and osteoporosis through bone densitometry between 2013 and 2016, who also had their vitamin D levels measured by means of any laboratory method. Sociodemographic characteristics, bone densitometry results as well as vitamin D, parathormone and ionic calcium levels were described. Results: A total of 300 patients with osteopenia and osteoporosis were included in the study, of which 211 had low levels of vitamin D, representing a prevalence of 71.3%. Finally, the average level of 25-hydroxyvitamin D was 24.35 ng/ml. Conclusion: The high prevalence of low levels of vitamin D in patients with osteopenia and osteoporosis highlights the importance to measure 25-hydroxyvitamin D levels in this population in order to carry out an appropriate therapeutic intervention.

ABSTRACT

BACKGROUND: Osteoporosis attacks approximately 10% of the population worldwide. Sika Deer (Cervus nippon), one of China's precious traditional medicinal animals, has been widely recorded in ancient Chinese medical books and claimed for centuries to have numerous medical benefits including bone strengthening. This study aimed to find the use of Sika Deer bone in treating osteoporosis according to traditional records and to investigate the protective effect of Sika Deer bone polypeptide extract on glucocorticoidinduced osteoporosis (GIOP) in rats. RESULTS: Sika Deer bone polypeptide extract could increase serum Ca2+ and BGP, decrease serum P3+, ALP, PTH, and CT, but had no effect on serum NO in rats with GIOP. The immunohistochemical iNOS results of the rats' distal femur were negative in each group. Besides the model group, the eNOS color reaction in osteoblasts was strongly positive in the other three groups. CONCLUSIONS: Sika Deer bone polypeptide extract can improve pathological changes in the microstructure and stimulate the expression of eNOS in osteoblasts. The protective effect on bone might be mediated by eNOS-dependent NO generation.

ABSTRACT

RESUMEN En los adultos mayores existen múltiples enfermedades que afectan su calidad de vida y el logro de una longevidad satisfactoria. Una de ellas es la osteoporosis, enfermedad de elevada incidencia a nivel mundial, lo cual también se refleja en Cuba. Siendo una afección que conlleva a un alto grado de discapacidad, constituye un problema en el campo de la salud y de magnitud epidémica, más aún cuando la supervivencia de la humanidad tiende al aumento. Con el objetivo de estructurar los referentes teóricos sobre la osteoporosis, que contribuyan a la capacitación de médicos y estudiantes de Medicina como promotores de salud en prevención primaria de esta enfermedad, se realizó el siguiente artículo científico. Los factores que predisponen la aparición de la enfermedad son diversos, algunos modificables. Se señaló la importancia de su prevención, diagnóstico y tratamiento, así como formas de actuar sobre la misma, para modificar estilos de vida en la comunidad (AU).


ABSTRACT There are many diseases affecting life quality and the achievement of a satisfactory longevity in elder people; osteoporosis, a disease of high incidence around the world that also strikes in Cuba, is found among them. It is an affection leading to a high disability level, being a problem in the health field with an epidemic magnitude, even more when the human kind survival tends to increase. The current scientific article was written with the objective of structuring the theoretical referents on osteoporosis contributing to train Medicine doctors and students as health promoters in the primary prevention of this disease. The factors predisposing the disease's appearance are different, some of them modifiable. It is also stated the importance of its prevention, diagnosis and treatment, and also forms and ways of working on it to modify life styles in the community (AU).

ABSTRACT

Abstract Osteoporotic vertebral fractures are a common type of fracture and affect a significant number of subjects with osteoporosis. Despite the high fracture risk, the concomitant occurrence of vertebral fractures at non-contiguous levels is very rare. We report the case of a patient with three burst dorsolumbar spine fractures at non-contiguous levels who was treated with percutaneous kyphoplasty and transpedicular posterior fixation. Six months after the surgery, the patient walks autonomously and without pain; in addition, there is no radiological evidence of fracture reduction loss.


Resumo As fraturas vertebrais osteoporóticas são um tipo comum de fratura e afetam um número significativo da população com osteoporose. Apesar do elevado risco de fratura, a ocorrência concomitante de fraturas vertebrais em níveis não contíguos é muito rara. Reportamos o caso de uma paciente com três fraturas explosivas da coluna dorsolombar em níveis não contíguos, tratada com cifoplastia e fixação posterior transpedicular por via percutânea. Seis meses após a cirurgia, a paciente tem marcha autônoma, sem dor, e, radiologicamente, não existem evidências de perda de redução das fraturas.

ABSTRACT

El FRAX es una herramienta que mide el riesgo de fractura y cuenta con un algoritmo computarizado desarrollado por la Organización Mundial de la Salud, basado en modelos globales de cohortes de población, combinados con factores de riesgo clínico. La herramienta fue diseñada inicialmente para su aplicación por los médicos de atención primaria en mujeres posmenopáusicas y hombres sobre 50 años, aunque es válida en general entre 40-90 años. Nos propusimos desarrollar un estudio epidemiológico-clínico sobre osteoporosis y fracturas en la población general y algunos grupos especiales de riesgo que incluyen mujeres posmenopáusicas, pacientes con afecciones reumáticas, endocrinas, cáncer y con infección por VIH, así como describir el papel desempeñado por FRAX como herramienta de medición del riesgo de fractura a los 10 años de ocurrida. Asimismo, constituye un gran reto conocer e identificar los principales grupos vulnerables o de riesgo para osteoporosis y fracturas en la población cubana. Esta aplicación nos resulta prioritaria en los grupos identificados, pues permitirá conocer los riesgos de fracturas a corto y largo plazos e implementar correcta y racionalmente los estudios DXA, disponibles en el país para la toma de decisiones terapéuticas(AU)


The FRAX is a tool that has a computerized algorithm developed by the World Health Organization, based on global models of population cohorts, combined with clinical risk factors, which measures the risk of fracture. The tool was initially designed for use by primary care physicians in postmenopausal women and men over 50 years of age, although it is generally valid between 40-90 years. We set out to develop a clinical epidemiological study on osteoporosis and fractures in the general population and some special risk groups that include post-menopausal women, patients with rheumatic, endocrine, cancer and HIV-infected conditions, as well as the role played by FRAX as a measurement tool. The ten-year risk of fracture related to the importance of knowing and identifying the main vulnerable or risk groups for osteoporosis and fractures in the Cuban population constitutes a great challenge. This application is a priority for those groups previously identified as it will allow us to know the short and long-term risks of fractures and implement the correct use of DXA studies, available in the country with a rational use and therapeutic decision-making(AU)

ABSTRACT

Introducción: Se ha descrito una probable asociación entre la presencia de osteopenia/osteoporosis y el riesgo incrementado de cardiopatía isquémica. Objetivo: Determinar la posible asociación entre la presencia de síndrome coronario agudo y la densidad mineral ósea disminuida, así como la relación de ambas condiciones con algunos factores de riesgo cardiovascular y variables de la esfera reproductiva en mujeres en etapa de climaterio. Método: Se realizó un estudio transversal descriptivo con 72 mujeres (34 con síndrome coronario agudo y 38 sin síndrome coronario agudo), que fueron seleccionadas de bases de datos del Instituto de Cardiología y Cirugía Cardiovascular. La densidad mineral ósea se determinó mediante absorciometría dual de rayos X en columna lumbar. Las pruebas Chi cuadrado y U de Mann Whitney permitieron evaluar la posible relación entre variables. Resultados: El 55,9 por ciento de las pacientes con síndrome coronario agudo y el 60,5 por ciento de las mujeres sin síndrome coronario agudo tenían densidad mineral ósea disminuida. En las mujeres con densidad mineral ósea disminuida (n=42): 81 por ciento presentaron obesidad abdominal, 78,6 por ciento dislipoproteinemia, 83,3 por ciento hipertensión arterial y 76,2 por ciento refirieron el antecedente familiar de cardiopatía isquémica. Conclusiones: En las mujeres en etapa de climaterio estudiadas no se demostró asociación entre la presencia de síndrome coronario agudo y la densidad mineral ósea disminuida. Tampoco existió relación entre la presencia de síndrome coronario agudo y la densidad mineral ósea disminuida con factores de riesgo cardiovascular, ni con las variables de la esfera reproductiva(AU)


Introduction: A probable association has been described between the presence of osteopenia/osteoporosis and the increased risk of ischemic heart disease. Objective: To determine the possible association between the presence of acute coronary syndrome and decreased bone mineral density, as well as the relationship of both conditions with some cardiovascular risk factors and variables of the reproductive sphere in women during the climacteric stage. Method: A descriptive and cross-sectional study was carried out with 72 women (34 with acute coronary syndrome and 38 without acute coronary syndrome), who were selected from databases of the Institute of Cardiology and Cardiovascular Surgery. Bone mineral density was determined by dual lumbar spine X-ray absorptiometry. The chi-square and Mann Whitney U tests allowed to evaluate the possible relationship between variables. Results: 55.9 percent of the patients with acute coronary syndrome and 60.5 percent of the women without acute coronary syndrome had decreased bone mineral density. Among women with decreased bone mineral density (n=42), 81 percent had abdominal obesity, 78.6 percent had dyslipoproteinemia, 83.3 percent had arterial hypertension, and 76.2 percent had a family history of ischemic heart disease. Conclusions: In the women in the climacteric stage studied, no association was shown between the presence of acute coronary syndrome and decreased bone mineral density. There was no relationship either between the presence of acute coronary syndrome and decreased bone mineral density with cardiovascular risk factors, or with variables in the reproductive sphere(AU)

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of zero-profile anchored spacer (ROI-C) in treating cervical spondylosis with osteoporosis.@*METHODS@#From May 2013 to May 2018, a total of 145 patients with cervical spondylosis were treated by ROI-C through anterior cervical spine approach. Among them, 31 patients were aged ≥60 years and had osteoporosis by bone density measurement, and they were retrospectively analyzed. Including 9 males and 22 females, aged 60-84 years old with an average of (69.12±7.65) years. There were 23 cases of single-segment fusion, 6 cases of two-stage fusion, and 2 cases of three-stage fusion;and 41 devices of ROI-C fusion was placed in the patients. Operation time and intraoperative blood loss were recorded;Japanese Orthopaedic Association (JOA) scores and visual analogue scale(VAS) were respectively used to evaluate the neurological function and neck pain before and after operation. The cervical curvature (expressed as Cobb angle), the height of the intervertebral space at the surgical segment, and the intervertebral fusion were observed at postoperative and follow-up periods were observed by image data.@*RESULTS@#All patients were followed up for 12-24(15.6±4.4) months after operation. The operation time were from 75 to 113 (101.33±10.25) min and intraoperative blood loss were from 14 to 51 (33.18 ± 16.56) ml. Among these 23 patients with fusion of single segment, the operation time were 75 to 98 (85.47±8.70) min and intraoperative blood loss were 14 to 30(21.18±6.56) ml. JOA scores of all included patients were increased from 9.66±2.12 preoperatively to 14.36±1.24 at the final follow-up (@*CONCLUSION@#Anterior cervical approach with ROI-C for the treatment of elderly patients with cervical spondylosis and osteoporosis had reliable clinical effect, short operation time, less intraoperative blood loss, and can effectively restore cervical curvature and intervertebral space height, and has advantages of fewer complications and higher successful rate of fusion.

ABSTRACT

Bone mass is a key determinant of osteoporosis and fragility fractures. Epidemiologic studies have shown that a 10% increase in peak bone mass (PBM) at the population level reduces the risk of fracture later in life by 50%. Low PBM is possibly due to the bone loss caused by various conditions or processes that occur during adolescence and young adulthood. Race, gender, and family history (genetics) are responsible for the majority of PBM, but other factors, such as physical activity, calcium and vitamin D intake, weight, smoking and alcohol consumption, socioeconomic status, age at menarche, and other secondary causes (diseases and medications), play important roles in PBM gain during childhood and adolescence. Hence, the optimization of lifestyle factors that affect PBM and bone strength is an important strategy to maximize PBM among adolescents and young people, and thus to reduce the low bone mass or osteoporosis risk in later life. This review aims to summarize the available evidence for the common but important factors that influence bone mass gain during growth and development and discuss the advances of developing high PBM.

ABSTRACT

Osteoporosis is one of the common metabolic diseases, which can easily lead to osteoporotic fractures. Accurate prediction of bone biomechanical properties is of great significance for the early prevention and diagnosis of osteoporosis. Bone mineral density measurement is currently used clinically as the gold standard for assessing bone strength and diagnosing osteoporosis, but studies have shown that bone mineral density can only explain 60% to 70% of bone strength changes, and trabecular bone microstructure is an important factor affecting bone strength. In order to establish the connection between trabecular bone microstructure and bone strength, this paper proposes a prediction method of trabecular bone modulus based on SE-DenseVoxNet. This method takes three-dimensional binary images of trabecular bone as input and predicts its elastic modulus in the z-axis direction. Experiments show that the error and bias between the predicted value of the method and the true value of the sample are small and have good consistency.

ABSTRACT

BACKGROUND@#The Fujiwara-kyo Osteoporosis Risk in Men (FORMEN) study was launched to investigate risk factors for osteoporotic fractures, interactions of osteoporosis with other non-communicable chronic diseases, and effects of fracture on QOL and mortality.@*METHODS@#FORMEN baseline study participants (in 2007 and 2008) included 2012 community-dwelling men (aged 65-93 years) in Nara prefecture, Japan. Clinical follow-up surveys were conducted 5 and 10 years after the baseline survey, and 1539 and 906 men completed them, respectively. Supplemental mail, telephone, and visit surveys were conducted with non-participants to obtain outcome information. Survival and fracture outcomes were determined for 2006 men, with 566 deaths identified and 1233 men remaining in the cohort at 10-year follow-up.@*COMMENTS@#The baseline survey covered a wide range of bone health-related indices including bone mineral density, trabecular microarchitecture assessment, vertebral imaging for detecting vertebral fractures, and biochemical markers of bone turnover, as well as comprehensive geriatric assessment items. Follow-up surveys were conducted to obtain outcomes including osteoporotic fracture, cardiovascular diseases, initiation of long-term care, and mortality. A complete list of publications relating to the FORMEN study can be found at https://www.med.kindai.ac.jp/pubheal/FORMEN/Publications.html .

ABSTRACT

BACKGROUND@#Body mass-independent parameters might be more appropriate for assessing cardiometabolic abnormalities than weight-dependent indices in Asians who have relatively high visceral adiposity but low body fat. Dual-energy X-ray absorptiometry (DXA)-measured trunk-to-peripheral fat ratio is one such body mass-independent index. However, there are no reports on relationships between DXA-measured regional fat ratio and cardiometabolic risk factors targeting elderly Asian men.@*METHODS@#We analyzed cross-sectional data of 597 elderly men who participated in the baseline survey of the Fujiwara-kyo Osteoporosis Risk in Men (FORMEN) study, a community-based single-center prospective cohort study conducted in Japan. Whole-body fat and regional fat were measured with a DXA scanner. Trunk-to-appendicular fat ratio (TAR) was calculated as trunk fat divided by appendicular fat (sum of arm and leg fat), and trunk-to-leg fat ratio (TLR) as trunk fat divided by leg fat.@*RESULTS@#Both TAR and TLR in the group of men who used ≥ 1 medication for hypertension, dyslipidemia, or diabetes ("user group"; N = 347) were significantly larger than those who did not use such medication ("non-user group"; N = 250) (P < 0.05). After adjusting for potential confounding factors including whole-body fat, both TAR and TLR were significantly associated with low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, fasting serum insulin, and the insulin resistance index in the non-user group and non-overweight men in the non-user group (N = 199).@*CONCLUSION@#The trunk-to-peripheral fat ratio was associated with cardiometabolic risk factors independently of whole-body fat mass. Parameters of the fat ratio may be useful for assessing cardiometabolic risk factors, particularly in underweight to normal-weight populations.

ABSTRACT

La enfermedad de Gaucher (EG) es un trastorno genético lisosomal autosómico recesivo infrecuente, que conduce a la acumulación de lípidos y disfunción en múltiples órganos. La afectación del esqueleto es uno de los hallazgos más frecuentes de la EG y una de las principales causas de dolor y reducción de calidad de vida. El compromiso esquelético incluye anomalías en el remodelado óseo con pérdida mineral ósea, adelgazamiento cortical, lesiones líticas, fracturas por fragilidad y deformidades articulares. A continuación presentamos el caso de una paciente 61 años con osteoporosis grave secundaria a EG diagnosticada en la vida adulta, con antecedente de dos hermanas con EG. La paciente refería dolores óseos y lumbago crónico desde los 53 años. El 2012 fue evaluada en policlínico de hematología por trombocitopenia y debido a sus antecedentes familiares se le solicitaron exámenes que fueron compatibles con EG. El año 2016 la densitometría ósea (DXA) de columna lumbar y cuello femoral izquierdo, que mostró una osteoporosis. Se inició tratamiento con Alendronato, Calcio y Vitamina D, pero la paciente tuvo escasa adherencia. El 2018 se inició tratamiento de su EG con Taliglucerasa α. Al año siguiente se le realizó nueva DXA que evidenció persistencia de la osteoporosis y por mantención del lumbago se le solicitó una TAC de columna lumbar que mostró fracturas por aplastamiento de cuerpos vertebrales dorsales bajos. Se derivó a endocrinología para manejo de su osteoporosis grave. A su ingreso a endocrinología la paciente persitía con dolor lumbar alto y destacaba una marcada cifosis. Se decidió retomar tratamiento con Alendronato, calcio y vitamina D, además, se le solicitó una nueva evaluación densitométrica junto a una radiografía de columna total y evaluación dental. Durante el seguimiento la paciente mantuvo niveles de vitamina D adecuados con funciones renal, hepática y tiroidea normales.


Gaucher disease (GD) is a rare autosomal recessive lysosomal genetic disorder, leading to the accumulation and dysfunction of lipids in multiple organs. Skeletal involvement is one of the most prevalent aspects of GD and one of the main causes of pain and reduced quality of life. Abnormalities of bones, which cause changes in the development and loss of bone mineral, cortical thinning, lytic lesions,fragility fractures and deformities. We present a case of a patient diagnosed with severe osteoporosis, secondary to GD diagnosed in adult life. The patient presents a disease pattern composed of bone pain and chronic low back pain since the age of 53. In 2012, she was evaluated at the hematology for thrombocytopenia and due to her family history, tests were performed to diagnose GD, which were compatible with it. In 2016 Bone Densitometry (DXA) of the lumbar spine and left femoral neck was requested, being consistent with osteoporosis. Treatment with Alendronate, Calcium and Vitamin D was started, however, there is little adherence. In 2018, treatment for Gaucher's disease was started with Taliglucerase α. The following year, DXA was performed with few changes and a CT scan of the lumbar spine was performed diagnosing crush fractures of the low dorsal vertebral bodies. She was referred to endocrinology. Upon admission to Endocrinology, it was decided to resume initial osteoporosis treatment and to perform skeletal evaluation with DXA of the lumbar spine and hips, total spine X-ray and dental evaluation. During follow-up, it maintains vitamin D at adequate levels and normal kidney, liver and thyroid functions.

ABSTRACT

Objective: Glucocorticoids induced osteoporosis and its related fragility fractures represent a costly human and socioeconomic load worldwide. All the current pharmacological therapies possess multiple adverse effects and high cost. Thus, the pesent study aimed to evaluate the bone healing ability of Moringa oleifera (MO) on glucocorticoids induced osteoporosis in the jawbone of Albino rats. Material and Methods: Osteoporosis was prompted by a daily intraperitoneal injection of 200 µg/ 100 g dexamethasone for 30 days. Next,the animals were randomly divided into 2 groups; osteoporotic and MO treated group. The treated group receivd a daily oral dose of 200mg/kg of MO. Rats from the MO group were sacrificed after 4 weeks from the beginning of treatment, and the same sacrifice date was used for the osteoporotic group. Bone regeneration was evaluated by dual energy x-ray absorptiometry (DEXA), real time polymerase chain reaction (RT-PCR), histopathological and histomorphometric examination. Results: After the sacrifice, the DEXA analysis revealed a significant upregulation in the BMD in the MO treated group (p <0.001). The RT-PCR test showed a significant decline in RANKL gene expression and a significant rise in OPG gene expression in the MO group (p < 0.001, p = 0.002, respectively). The histopathological examination of the MO group displayed a marked healing of the jawbone micro-anatomy. The histomorphometric analysis also showed that the bone area percentage increased significantly in the MO group (p <0.05). Conclusion: A cheap, easy to get, yet a powerful plant like MO leaves, can be cosidered an effective treatment for osteoporosis (AU).


Objetivos: A osteoporose induzida por glicocorticóides e suas fraturas por fragilidade relacionadas representam um custo humano caro e carga socioeconômica em todo o mundo. Todas as terapias farmacológicas atuais possuem múltiplos efeitos adversos e alto custo. Assim, o presente estudo teve como objetivo avaliar a capacidade de cicatrização óssea de Moringa oleifera (MO) em osteoporose induzida na mandíbula de ratos albinos. Material e Métodos: A osteoporose foi induzida por uma injeção intraperitoneal diária de 200 µg / 100 g de dexametasona por 30 dias. A seguir, os animais foram divididos aleatoriamente em 2 grupos; grupo tratado com osteoporose e MO. O grupo tratado recebeu uma diária dose oral de 200 mg / kg de MO. Os ratos do grupo MO foram eutanasiados após 4 semanas do início do tratamento, e a mesma data de eutanásia foi usada para o grupo osteoporótico. A regeneração óssea foi avaliada por espectrometria de raio-x de energia dupla (DEXA), reação em cadeia da polimerase em tempo real (RT-PCR), análise histopatológica e histomorfométrica. Resultados: Após a eutanásia, a análise DEXA revelou uma regulação positiva significativa na DMO no grupo tratado com MO (p <0,001). O teste RT-PCR mostrou um declínio significativo na expressão do gene RANKL e um aumento significativo na expressão do gene OPG no grupo MO (p <0,001, p = 0,002, respectivamente). O exame histopatológico do grupo MO revelou uma cicatrização acentuada da microanatomia do maxilar. A análise histomorfométrica também mostrou aumento significativo na porcentagem de área óssea no grupo MO (p <0,05). Conclusão: A MO é uma planta barata, de fácil obtenção, e suas folhas ainda podem ser consideradas poderosas como tratamento eficaz para a osteoporose. (AU)

ABSTRACT

Objective: The objective of this study was to evaluate mandibular osteoporotic alterations in patients with HIV infection in comparison to non-HIV-infected patients using panoramic radiographs. Material and Methods: 26 HIV-infected patients and 142 non-HIV-infected patients (control group) were included in this study. Panoramic radiographs of the participants were assessed considering mandibular cortical index (MCI). Non-parametric comparisons between groups were performed, using Mann-Whitney test, at a level significance level of p= 0.05. Results: HIV-infected patients presented lower bone mineral density (BMD) at mandible, assessed by MCI in panoramic radiographs when compared to non-HIV-infected patients. The medication intake of HIV-infected patients was highly heterogeneous and could not be associated to the low BMD presented in the mandibular cortex. Conclusions: HIV-infected patients may present lower mandibular BMD than non-HIV-infected patients. (AU)


Objetivo: O objetivo deste estudo foi avaliar as alterações osteoporóticas mandibulares em pacientes com infecção por HIV comparando-os com pacientes não infectados, por meio de radiografias panorâmicas. Material e Métodos: 26 pacientes infectados pelo HIV e 142 pacientes não infectados (grupo controle) foram incluídos neste estudo. As radiografias panorâmicas dos participantes foram avaliadas considerando o índice da cortical mandibular (MCI). Comparações não paramétricas entre os grupos foram realizadas, com o teste de Mann-Whitney e nível de significância de p = 0,05. Resultados: Pacientes infectados pelo HIV apresentaram menor densidade mineral óssea (BMD) na mandíbula, avaliada pelo MCI em radiografias panorâmicas, quando comparados aos pacientes não infectados pelo HIV. A ingestão de medicamentos de pacientes infectados pelo HIV foi altamente heterogênea e não pôde ser associada à baixa BMD apresentada no córtex mandibular. Conclusões: Pacientes infectados pelo HIV podem apresentar BMD mandibular menor do que pacientes não infectados pelo HIV. (AU)
