Association of acanthosis nigricans with metabolic syndrome - An analytic cross-sectional study

Abstract Background: Globally, few studies have been undertaken to assess the association of acanthosis nigricans (AN) with metabolic syndrome (MS). Most of the available studies have either focused on a particular age group, gender, ethnicity or on a single component of MS. Objectives: To determine the association between AN and MS as a whole and with all individual components of MS in adult patients of either gender. Material and methods: This was a cross-sectional study with a comparative group. Eighty-one subjects were recruited in each group. Fasting plasma glucose (FPG) and lipid profile were done. MS was defined by using the international diabetic federation (IDF) criteria. Association of body mass index (BMI), waist circumference, blood pressure, FPG, high-density lipoprotein (HDL) and triglycerides (TG) with AN was assessed by Pearson's chi-square test followed by univariate and multivariate analysis. Results: The prevalence of MS was found to be significantly higher in the group with AN. On univariate analysis, a significant association of AN was found with BMI, waist circumference, high systolic and diastolic blood pressure, HDL, and TG. Multivariate analysis revealed a significant association between waist circumference, high systolic and diastolic blood pressure, and high TG levels with AN. The risk of MS was found to be eight times higher in cases of AN. Study limitations: The small sample size and single-center data are the limitations of the present study. Conclusion: AN is strongly associated with MS as a whole and with its individual components including increased waist circumference, hypertension, and dyslipidemia.

Association between acanthosis nigricans and overweight with hypertension in children and adolescents from low-income families

SUMMARY OBJECTIVE: This study aimed to describe the prevalence of acanthosis nigricans and high blood pressure in children and adolescents from low-income families, and to verify the association of elevated blood pressure with nutritional status and the presence of acanthosis nigricans. METHODS: This is a cross-sectional and controlled study with 232 children and adolescents from an institution for low-income families. Pubertal stage, body mass index Z-score, waist-to-height circumference ratio (increased waist-to-height circumference ratio >0.5), the presence of acanthosis nigricans, and blood pressure were assessed. RESULTS: The prevalence of excess weight and the change in waist-to-height circumference ratio was 37.9%. Acanthosis nigricans and increased blood pressure occurred in 20.3 and 34.8%, respectively. The prevalence of acanthosis nigricans and hypertension was higher in individuals with excess weight (p<0.001; p<0.001) and with an increased waist-to-height circumference ratio (p=0.009; p<0.001). Logistic regression showed a significant and independent association of body mass index Z-score (OR 2.35; 95%CI 1.52-3.65; p<0.001) and the presence of acanthosis nigricans (OR 2.43; 95%CI 1.12-5.23; p=0.023) with elevated blood pressure. CONCLUSION: Acanthosis nigricans and elevated blood pressure occurred in one-fifth and one-third of the individuals in an institution for children from low-income families. Overweight and the presence of acanthosis nigricans increased the risk of high blood pressure more than twofold.

Diagnosis of acanthosis nigricans in a family by targeted sequencing / 中华皮肤科杂志

A pedigree with familial acanthosis nigricans presenting with atypical clinical symptoms was reported. The 4-year-old female proband began to develop black patches on the neck and abdomen since the age of 1 year, which had gradually spread to the lips and front of the trunk in recent years. Reflectance confocal microscopy of the abdominal skin showed downward extension and twisting of dermal papillary rings with formation of gully-like structures, and moderately to highly refractive particles in the dermal papillary rings. The proband′s father and grandmother had similar medical history, but the pigmentation spontaneously subsided with age, leaving only local thickened skin lines. Peripheral blood samples were collected from the proband, her parents and grandmother, and panel-based targeted sequencing of peripheral blood DNA was performed for the proband. Sequencing showed a missense mutation c.1949A>C (p.Lys650Thr) in exon 14 of the FGFR3 gene in the proband, and Sanger sequencing confirmed the presence of this mutation in the proband and her father and grandmother. A diagnosis of familial acanthosis nigricans was made.

Histopathological Features and Clinical Variants of Biopsy Confirmed Psoriasis Cases in a Tertiary Care Setting in Kerala.

Psoriasis is a chronic, immune mediated, relapsing, papulosquamous disease having a high prevalence. Since it affects other organ systems such as musculoskeletal system, gastrointestinal system and the eye, it can lead to considerable disability. Although only rarely life threatening, it has high morbidity due to its chronicity and absence of cure. MethodsThis study was conducted over a period of 2 years in the Department of Pathology, Medical College, Thiruvananthapuram. A total of 217 skin biopsy specimens in which a clinical diagnosis / differential diagnosis of psoriasis was made, was studied during this period. Results108 cases out of 217 which were histopathologically diagnosed as psoriasis were studied in detail. Male predominance was noted in the study population. The mean duration of disease in this study was 6.69 yrs. Fifty percentage of the patients had associated comorbidities with hypertension outnumbering others. Among male patients, 26 (32.5 %) had the habit of smoking. The most common presentation was as erythematous scaly plaques, with pruritus being the second most common presentation. Histopathology proved to be conclusive of psoriasis in all cases. Hyperkeratosis was seen in all cases which was the most consistent histopathological feature. Confluent parakeratosis which is one of the characteristic features of psoriasis was seen in 62 (57.4 %) cases with the rest being focal. Other epidermal features studied were papillomatosis, hypogranulosis, suprapapillary thinning, and basal mitotic figures. Spongiosis was seen in 83 (76.9 %), exocytosis of neutrophils in 66 (61.1 %) and Munro’s micro abscess in 42 (38 %) cases. Dilated blood vessel was the most common dermal change observed, seen in 105 (97 %). Lymphocytes were the most frequent upper dermal inflammatory infiltrate observed. Oedema was seen in 5 (4.6 %) of cases. ConclusionsPsoriasiform lesions pose diagnostic dilemma to the treating clinician. To provide a clear-cut diagnosis, histopathological evaluation is essential. It is also important to differentiate between the different variants of psoriasis in the context of treatment. It has an important role in the follow up of psoriatic patients.

RESUMEN Objetivo: comparar la frecuencia de enfermedad nodular tiroidea (ENT) en pacientes con síndrome metabólico (SM) y en pacientes sin SM en un área yodosuficiente. Materiales y métodos: estudio analítico, de casos y controles, comparativo de grupos pareados. Fueron 40 pacientes con SM y 40 controles, pareados por edad y sexo, los cuales acudieron al servicio de Endocrinología del Hospital Cayetano Heredia, Lima - Perú. El peso, talla y la presión arterial fueron tomadas de la historia clínica. Se evaluó el perímetro abdominal y la presencia de acantosis nigricans. Se midió perfil lipídico, glucosa basal y TSH. Se realizó ecografía tiroidea a todos los participantes. Se midió el volumen tiroideo y se consideró clínicamente significativo a nódulos tiroideos > 5 mm. Resultados: el 80 % de la población estudiada en ambos grupos fueron mujeres. Hubo diferencias significativas en el hábito tabáquico, la acantosis nigricans, la TSH, el volumen tiroideo, peso, índice de masa corporal, perímetro abdominal, presión diastólica, glucosa basal, HDL-colesterol y triglicéridos entre ambos grupos. La ENT fue más frecuente en los pacientes con SM que en los pacientes sin SM (40% vs. 12,5% respectivamente, p = 0,015). El odds ratio (OR) para presentar nódulos tiroideos en presencia de SM fue de 4,66 (intervalo de confianza al 95%: 1,34 - 16,24). Hubo diferencia significativa en el volumen tiroideo entre ambos grupos (p = 0,039). Conclusión: en una población de una zona yodosuficiente, el SM estuvo asociado a ENT y al incremento del volumen tiroideo.

ABSTRACT: Objective : To compare the frequency of thyroid node disease (TND) in patients with metabolic syndrome (MS) and in patients without metabolic syndrome in an area with good iodine supply. Materials and Methods : This is an analytical comparative case- control study performed in paired groups. There were 40 patients with MS and 40 controls attending the Endocrinology service in Cayetano Heredia Hospital in Lima, Peru, who were paired according to age and sex. Weight, height, and blood pressure measurements were taken from clinical records. Abdominal circumference was measured, and the presence of acanthosis nigricans was determined. Lipid profile, baseline blood glucose and TSH were determined. Thyroid ultrasonography was performed in all participants. Thyroid volume values were recorded and thyroid nodes measuring >5-mm were considered as clinically significant. Results : Eighty per cent of the studied population in both groups was women. There were significant differences in tobacco use, acanthosis nigricans, TSH levels, thyroid volume, weight, body mass index, abdominal circumference, diastolic blood pressure, baseline blood glucose, HDL-cholesterol and triglyceride levels between both groups. TND was more frequent in those patients with MS compared to patients with no MS (40% vs. 12.5%, respectively; p= 0.015). The odds ratio (OR) for having thyroid nodes in the presence of MS was 4.66 (95% confidence interval: 1.34-16.24). There were significant differences in thyroid volume for both groups (p= 0.039). Conclusion : In an area with good iodine supply, MS was associated to TND to with an increased thyroid volume.

ABSTRACT Objective : to explore whether there is an association between the frequency of insulin resistance and the presence and distribution of acanthosis nigricans in obese children. Materials and methods : this is a cross-sectional study in which 42 obese children between 5 and 10 years of age participated. The presence of acanthosis nigricans was characterized (number and distribution of affected areas) as well as other variables, such as age, sex, and Body Mass Index. Four groups were formed, and the frequency of insulin resistance was determined, aiming to explore its association with the other variables. Results : mean participants' age was 8.6 years, and male subjects accounted for 54.8%. Nearly two-thirds of participants (64.3%) had acanthosis nigricans, and 78% of them had insulin resistance. Associated variables with statistical significance were age (p= 0.009), BMI (p= 0.025), and the presence of acanthosis nigricans affecting the neck region. Conclusions : there is an association between insulin resistance and the presence of acanthosis nigricans affecting the neck of obese children.

Study of clinical characteristics of women with polycystic ovarian syndrome

Background: Polycystic ovarian syndrome (PCOS) is one of the most common endocrinal disorders of the reproductive age group causing anovulation, infertility incidence being 8.7-17.8%. It is associated with obesity, insulin resistance, dyslipidaemia and metabolic syndrome. This study was aimed to study the different clinical characteristics of women diagnosed with PCOS, attending a tertiary care hospital outpatient department.Methods: This was a hospital-based cross-sectional observational study of 200 patients with PCOS meeting the revised Rotterdam criteria from January 2018-June 2019 excluding pregnant and women with other systemic disorders. A detailed history and examination done, data collected regarding menstrual complaints, features of hyperandrogenism, hirsutism, acne, oily skin and Acanthosis Nigricans (AN) was documented. All data were statistically analyzed and compared using the chi-square or fissures’ exact test. p-value <0.05 considered significant.Results: A total of 200 patients with PCOS were included in the study, of which 41% were obese, 18% lean. The mean age was 24.44±5.62 years. Menstrual complaints were present in 88% -oligomenorrhea (49%) being the most common. 59% had hirsutism,38% of severe grade. Acanthosis nigricans was present in 33% of the patients. Correlation between hirsutism and alopecia, waist to hip ratio (WHR); acanthosis and WHR were statistically significant.Conclusions: PCOS is an ill-defined symptom complex where ethnicity plays a vital role, hence creating a greater need to know the characteristics of the syndrome in different populations and ethnicity. All women presenting with oligomenorrhea or other menstrual complaint should be investigated for PCOS and treated accordingly. The syndrome usually occurs with multiple characters. Though obesity is common in PCOS, non-obese are also at risk. The prevalence of AN and Hirsutism in PCOS were comparable. This mandates a need to increase awareness regarding the syndrome in the general population.

A Simple Assessing Method for Screening Prevalence of Polycystic Ovary Syndrome (The Thief of Womanhood) and Emotional Distress in Female Students at Northern Border University (NBU) in Arar, Kingdom of Saudi Arabia (KSA)

Background: Polycystic ovary syndrome (PCOS) is an endocrine condition which is caused due to disturbance in hormonal balances. There are more than one influencing factors that can lead to cause of PCOS. Yet, there are few reports that have fully elucidated the connection of conventional factors linked with PCOS so far. Aim and objectives: 1. To study the prevalence of risk factors associated with PCOS among female students of NBU, Arar, KSA. 2. To study the correlation between emotional distress and associated risk factors of PCOS among female students of NBU. 3. To create the awareness of PCOS and its associated risk factors among female students of NBU. Material and methods: The Northern Border University female students those were willing to participate were selected to enroll in our study. A pre-validated self-structured questionnaire was used as a tool for the collection of the data. Students were grouped into two viz PCOS-group and non-PCOS-group founded on criteria’s given by NIH (National Institutes of Health Criteria). As per this criteria diagnosis of PCOS is established founded on incidence of both chronic anovulation (ANOVU) characterized by occurrence of vaginal bleeding for more than 35 days gaps or 8 cycles/year to understand absence of menstruation and clinical hyperandrogenism (CH). CH is defined as the occurrence of acne, androgenic alopecia, acanthosis and hirsutism. Conclusion: Students recognized with linked risk factors for PCOS were guided and counseled to have complete investigations done including radiological and hormonal assays for confirming diagnosis and starting treatment.

Study of cutaneous manifestations of polycystic ovarian syndrome

Background: Polycystic ovarian syndrome (PCOS) is one of the most frequently encountered endocrine disorders that occurs in as many as 4 to 10% of women of reproductive age group. It presents with a series of skin changes including acne, hirsutism, seborrhea, androgenetic alopecia (AGA) and acanthosis nigricans. Aim of the study was to determine the prevalence and frequency of different cutaneous manifestations in PCOS patients and to correlate them with the degree of hormonal abnormalities.Methods: A total 100 patients with features of PCOS who presented to department of dermatology, gynecology (January 2018-December 2019) with cutaneous manifestations were recorded and diagnosis of PCOS was made using Rotterdam’s criteria. Pregnant women and diagnosed cases of any other endocrine disorder were excluded. Hirsutism was assessed using Ferriman-Gallwey score and AGA according to Ludwig’s classification. Serum hormonal profile including FSH, LH, prolactin, testosterone (free), DHEAS, TSH, FBS, fasting insulin were done. Insulin resistance was determined by calculating HOMA-IR score.Results: Among cutaneous manifestations of PCOS, hirsutism (85%) was the most common finding followed by acne (73%), seborrhea (50%), AGA (36%), acanthosis nigricans (29%) and acrochordons (9%). The most common hormonal abnormality was insulin resistance in 53% patients, followed by raised free testosterone in 19% and serum prolactin in 18% patients. A statistically significant association was present between AGA and insulin resistance, hirsutism and raised prolactin levels, seborrhea and raised body mass index (p < 0.05).Conclusions: Dermatological manifestations of PCOS play a significant role in making the diagnosis and constitute a substantial portion of the symptoms experienced by women with this syndrome.

Correlation of Atherosclerosis with Acanthosis Nigricans of Temporal Region of Face Compared to Neck

Introduction: Acanthosis nigricans (AN) is a dermatosisthat clinically manifests as asymptomatic and symmetricaldarkening of the skin, and it is associated with hyperinsulemia,obesity and metabolic syndrome. Previous studies have shownan increased risk of Acanthosis nigricans and atherosclerosis.Aim: To study correlation of atherosclerosis with Acanthosisnigricans of temporal region of face compared to neck, asassessed by carotid intima media thickness.Material and Methods: The study included 66 patients whoare clinically diagnosed as Acanthosis nigricans of temporalregion of face and 66 patients with Acanthosis nigricans ofneck, attending the outpatient department of dermatology,Amala Institute of Medical Sciences, Thrissur betweenJanuary 2017 – September 2018. All patients were screenedfor diabetes mellitus and for insulin resistance by measuringfasting blood sugar, and insulin level. The two groups weresent to measure the Carotid Intima Media Thickness (CIMT).CIMT values ≥ 75th percentile are considered high andindicative of increased CVD risk.Result: The mean CIMT in group 1 and group 2 were0.8192 and 0.6159 respectively. The mean CIMT of patientswith Acanthosis nigricans over temporal region of face inour study was 0.8192 which was higher compared with themean CIMT of patients with Acanthosis nigricans over neck(p value is - 0.001).Carotid plaque was present in 4 patientswith Acanthosis nigricans over temporal region of face. Ingroup one, 28 patients (42%) had increased CIMT value (≥75thpercentile) and in group two, 11 patients (16.6%) hadincreased CIMT value. In our study, increased CIMT wasassociated with metabolic syndrome, insulin resistance,diabetes mellitus, hypertension and hypertriglyceridemia.Conclusion: There is higher prevalence of atherosclerosis inpatients with Acanthosis nigricans over temporal region offace (42.42%).This suggest that there is an increased chancefor cardiovascular events.

Intraoral acanthosis nigricans and its clinical relevance as a manifestation of a paraneoplastic syndrome: a case report / Acantosis nigricans intraoral y su relevancia clínica como manifestación de un síndrome paraneoplásico: reporte de un caso

Malignant-or-paraneoplastic acanthosis nigricans is a verrucous and hyperpigmented tumor affecting the mucosa and skin. In most cases malignant acanthosis nigricans is a distant manifestation of an intra-abdominal primary cancer. While the diagnosis of malignant acanthosis nigricans is challenging, some specific clinical and histopathological findings could lead to an accurate diagnosis. A rare clinical case of a 59-year-old female, who was referred to the maxillofacial surgery service due to a painful oral lesion in the palatine region, is presented. Upon examination, papillomatous lesions were observed on the hard palate, that were later diagnosed as intraoral malignant acanthosis nigricans secondary to gastric cancer. Both local and systemic evaluations are discussed, highlighting the relevance of a multidisciplinary approach consistent with the fact that these manifestations, although infrequent, should generate suspicion among clinicians and therefore motivation to perform a diligent and complete study since it can reveal the presence of a malignant pathology.

La acantosis nigricans maligna o paraneoplásica es un tumor verrugoso e hiperpigmentado que afecta la mucosa y la piel. En la mayoría de los casos, la acantosis nigricans maligna es una manifestación distante de un cáncer primario intraabdominal. Si bien el diagnóstico de acantosis nigricans maligna es desafiante, algunos hallazgos clínicos e histopatológicos específicos podrían conducir a un diagnóstico preciso. Se presenta un caso clínico raro de una mujer de 59 años, que fue derivada al servicio de cirugía maxilofacial debido a una lesión oral dolorosa en la región palatina. En el examen, se observaron lesiones papilomatosas en el paladar duro, que posteriormente se diagnosticaron como acantosis nigricans maligna intraoral secundaria a cáncer gástrico. Se discuten tanto las evaluaciones locales como las sistémicas, destacando la relevancia de un enfoque multidisciplinario consistente con el hecho de que estas manifestaciones, aunque poco frecuentes, deberían generar sospecha entre los clínicos y, por lo tanto, motivación para un estudio diligente y completo, ya que puede revelar la presencia de una patología maligna.

Tripe palm: a paraneoplastic manifestation of carcinoma stomach

Usually gastrointestinal malignancies present with low SAAG ascites. But when there is diffuse liver infiltration following malignancy, high SAAG ascites can occur. So liver infiltration can masquerade as cirrhosis. Malignant acanthosis and tripe palm are the paraneoplastic manifestations seen in GI malignancies. We are reporting a case which was initially managed as a  straightforward case of cirrhosis ,but later turned out to be a case with tripe palms, malignant acanthosis and carcinoma stomach as primary with diffuse liver infiltration having high SAAG ascites.

Acanthosis nigricans as a clinical marker of insulin resistance among overweight adolescents

PURPOSE: Acanthosis nigricans (AN) is a hyperpigmented dermatosis associated with obesity and insulin resistance (IR). There is no consensus whether AN extension scoring offers added value to the clinical estimation of IR. In this study we aimed to assess and score AN using both a short and an extended version of the scale proposed by Burke et al. and analyze the relationships of both versions with hyperinsulinemia and IR. METHODS: We analyzed data from 139 overweight adolescents (body mass index ≥85th percentile) aged 12–18 with (n=67) or without (n=72) AN who were followed at a pediatric obesity clinic. RESULTS: Adolescents with AN had higher levels of insulin (d=0.56, P=0.003) and HOMA-IR (d=0.55, P=0.003) compared to those without. Neither the short nor the extended versions of AN scores explained either hyperinsulinemia (β=1.10, P=0.316; β=1.15, P=0.251) or IR (β=1.07, P=0.422; β=1.10, P=0.374). The presence of AN alone predicted hyperinsulinemia and the presence of IR in 7.3% (β=2.68, P=0.008) and 7.1% (β=2.59, P=0.009) of adolescents, respectively. CONCLUSIONS: Screening for AN at the neck and axilla is a noninvasive and cost-effective way to identify asymptomatic overweight adolescents with or at risk of developing IR.

Associação entre acantose nigricans e outros fatores de risco cardiometabólico em crianças e adolescentes com sobrepeso e obesidade / Association between acanthosis nigricans and other cardiometabolic risk factors in children and adolescents with overweight and obesity

RESUMO Objetivo: Avaliar em um grupo de crianças e adolescentes com obesidade e sobrepeso a presença ou não de acantose nigricans e sua associação com alterações metabólicas. Métodos: Estudo transversal envolvendo 161 indivíduos com excesso de peso, que foram divididos em dois grupos, segundo a presença ou não de acantose nigricans, e nos quais foram obtidas medidas antropométricas (índice de massa corporal, pregas cutâneas, circunferência abdominal), pressão arterial, análises laboratoriais (glicemia de jejum, insulina, perfil lipídico, triglicerídeos, ácido úrico, transaminases) e o índice homeostasis model assessment. Resultados: O grupo com acantose nigricans representou 51,5% da amostra. A média de idade foi semelhante entre os grupos. O grupo com acantose nigricans apresentou maiores índice de massa corporal, escore Z do índice de massa corporal, percentual de gordura corporal, circunferência abdominal (p<0,0001) e pressão arterial sistólica (p=0,006) e diastólica (p=0,002). Não houve diferença significativa na análise do perfil lipídico, exceto o colesterol de alta densidade, que foi menor (p=0,003) no grupo com acantose. Já o ácido úrico (p<0,0001), a glicemia de jejum (p=0,006), a insulina (p<0,0001), a transaminase glutâmica oxalacética (p<0,0001) e o índice homeostasis model assessment (p<0,0001) foram significativamente maiores no grupo com acantose nigricans. Conclusões: Acantose nigricans em crianças e adolescentes com sobrepeso e obesidade esteve associada à elevação dos índices de adiposidade corporal, pressão arterial, insulina e homeostasis model assessment, indicando-a como marcador clínico associado à síndrome metabólica.

ABSTRACT Objective: To evaluate the presence or absence of acanthosis nigricans and its association with metabolic alterations in a group of obese and overweight children and adolescents. Methods: A cross sectional study of 161 overweight children and adolescents, who were divided into two groups, according to presence or absence of acanthosis nigricans. Anthropometric measurements (body mass index, skinfolds, abdominal circumference), blood pressure, laboratory tests (fasting glycemia, insulin, lipid profile, triglycerides, uric acid, transaminases) and homeostasis model assessment index. Results: The acanthosis nigricans group represented 51.5% of the sample. The mean age was similar between groups. The group with acanthosis nigricans presented higher body mass index, Z score of body mass index, body fat percentage, abdominal circumference (p<0.0001), systolic (p=0.006) and diastolic blood pressure (p=0.002). There was no significant difference in the analysis of lipid profile, except for the high-density cholesterol, which was lower (p=0.003) in the group with acanthosis. On the other hand, uric acid (p<0.0001), fasting glycemia (p=0.006), insulin (p<0.0001), glutamic oxalacetic transaminase (p<0.0001), and homeostasis model assessment index (p<0.0001) were significantly higher in the group with acanthosis nigricans. Conclusions: Acanthosis nigricans in overweight and obese children and adolescents is associated with elevation of body fat, blood pressure, insulin and homeostasis model assessment index, indicating that it is a clinical marker associated with the metabolic syndrome.

Trastornos asociados y factores de riesgo aterogénicos en escolares y adolescentes obesos / Associated disorders and atherogenic risk factors in obese school children and adolescents

Introducción: la obesidad en la edad pediátrica predispone a la enfermedad aterosclerótica precoz en la adultez, independientemente del peso futuro. Objetivo: caracterizar el patrón antropométrico, morbilidad asociada y factores de riesgo aterogénico en obesos. Métodos: se realizó un estudio descriptivo y prospectivo con 62 pacientes obesos atendidos en la consulta de Endocrinología del Hospital Pediátrico William Soler , entre enero y diciembre de 2016. Fueron analizadas variables demográficas, antropométricas y de riesgo aterogénico por medio de prevalencia (por ciento) y pruebas de hipótesis (significativo: p< 0,05 o coeficiente Eta 1). Resultados: la obesidad fue significativa en escolares y el sexo masculino (p= 0,000). La obesidad abdominal (n= 48/77,4 por ciento) predominó en el sexo femenino (n= 20/90,9 por ciento), y entre los 6 y 10 años (n= 14/63,6 por ciento). La obesidad generalizada tuvo diagnóstico significativamente superior que la obesidad abdominal (p= 0,001) y fue independiente del sexo (Eta= 0,049) y la edad (p= 0,066). La prevalencia de acantosis nigricans (n= 39/62,9 por ciento) fue significativa (p= 0,042). Las alteraciones humorales, clínicas y ecográficas analizadas se manifestaron por encima de 70 por ciento en presencia de obesidad abdominal y la generalizada, ambas asociadas con elevación de proteína C reactiva (p< 0,05), y a su vez, la generalizada con remodelación ventricular izquierda (p= 0,049). Conclusión: la obesidad es distintiva de los escolares y del sexo masculino, pero la de tipo abdominal caracteriza a las niñas; existe una baja prevalencia de factores de riesgo aterogénico en los pacientes estudiados. La adiposidad abdominal y la generalizada implican un incremento de la proteína C reactiva plasmática; se evidencia el remodelado ventricular izquierdo cuando existe obesidad generalizada(AU)

Introduction: obesity in the pediatric age predisposes to early atherosclerotic disease in adulthood, regardless of future weight. Objective: to characterize the anthropometric pattern, associated morbidity and atherogenic risk factors in obese patients. Methods: a descriptive and prospective study was carried out with 62 obese patients attended in the Endocrinology clinic of William Soler Pediatric Hospital, from January to December 2016. Demographic, anthropometric and atherogenic risk variables were analyzed by means of prevalence (percent) and hypothesis testing (significant: p< 0.05 or Eta coefficient 1). Results: obesity was significant in schoolchildren and male sex (p= 0.000). Abdominal obesity (n= 48/77.4 percent) predominated in females (n= 20/90.9 percent), and among 6 and 10 years old (n= 14/63.6 percent). Generalized obesity had a significantly higher diagnosis than abdominal obesity (p = 0.001) and didn´t have relation with sex (Eta= 0.049) and age (p= 0.066). The prevalence of acanthosis nigricans (n= 39 / 62.9 percent) was significant (p= 0.042). The humoral, clinical and ultrasonographic alterations analyzed were above 70 percent in the presence of abdominal and generalized obesity, both associated with elevated C-reactive protein (p< 0.05), and at the same time, the generalized with left ventricular remodeling (p= 0.049). Conclusions: obesity is distinctive among school children and males, but abdominal type characterizes girls. There is a low prevalence of atherogenic risk factors in the patients studied. Abdominal and generalized adiposity imply an increase in plasma C-reactive protein. Left ventricular remodeling is evidenced when there is generalized obesity(AU)

Acanthosis Nigricans: A Marker Of Metabolic Syndrome Among Obese Children

xThis was a prospective case controlled study to determine the association of Acanthosis Nigricans (AN) and Metabolic Syndrome (MS) in obese children 10–16 years of age. We recruited 50 obese children with AN (cases) and 50 obese children without AN (controls) attending the Pediatric OPD from May 2013 to August 2014 after obtaining informed consent from their parents. Children were defined as obese if their BMI was ≥ 95th percentile for age and sex (CDC). International Diabetes Federation (IDF) 2007 criteria were used to define MS. Detailed history, physical examination, anthropometry and blood sampling were done in each case. Samples for High Density Lipoprotein Cholesterol (HDL-C), Fasting Plasma Glucose (FPG) and Triglycerides (TG) were evaluated at the in-hospital NABL certified SRL laboratory. MS was found in 64% of obese children with AN as compared to 30% of obese children without AN which was highly significant. Therefore, AN is a significant marker of MS.
