Relationship between adiponectin and blood pressure in obese Latino adolescent boys with a family history of type 2 diabetes.

INTRODUCTION: Adipokines are associated with several pathological states including, metabolic syndrome, obesity, insulin resistance and type 2 diabetes. One of these adipokines, adiponectin is of particular interest as it has been shown to have numerous anti-inflammatory effects, However, the association between adiponectin and blood pressure remains inconclusive especially in the Latino adolescent with obesity. PURPOSE: To investigate the relationship between plasma adiponectin and blood pressure in Latino adolescents' boys with obesity and a with a family history of Type 2 diabetes. METHODS: Thirty two Latino adolescent males with obesity aged 14-17 years with a family history of type 2 diabetes underwent a frequently sampled glucose tolerance test (FSIVGTT) to measure insulin sensitivity. Body composition was assessed using dual energy x-ray absorptiometry. Obesity was defined as having a BMI percentile ≥95. Blood pressure was assessed using the Dinamap automated blood pressure monitor, and the average of three readings was used in the analysis. Fasting plasma adiponectin was determined using radioimmunoassay. RESULTS: There were moderate positive significant correlations for adiponectin and Systolic blood pressure(SBP) (rho = 0.436, p < 0.027) and Diastolic blood pressure(DBP) (rho = 0.41,p < 0.028). A multivariate liner regression showed that plasma adiponectin could significantly detect 19% of the variance in SBP (p = 0.017, and 33% for DBP (p = 0.017). In a simple linear regression adiponectin was not related to any of our variables (p < 0.05). CONCLUSION: In conclusion, adiponectin was positively and significantly correlated to blood pressure in Latino adolescent with obesity. Future studies should investigate this relationship in a large sample of Latino adolescent youth.

One of these adipokines, adiponectin is of particular interest as it has been shown to have numerous anti-inflammatory effects, However, the association between adiponectin and blood pressure remains inconclusive especially in the obese Hispanic adolescent. PURPOSE: to investigate the relationship between plasma adiponectin and blood pressure in obese Latino adolescents' boys with a family history of Type 2 diabetes. METHODS: Thirty two obese Latino male adolescents aged 14-17 years with a family history of type 2 diabetes underwent a frequently sampled glucose tolerance test (FSIVGTT) to measure insulin sensitivity. Body composition was assessed using dual energy x-ray absorptiometry. Obesity was defined as having a BMI percentile 395. Blood pressure was assessed using the Dinamap automated blood pressure monitor, and the average of three readings was used in the analysis. Fasting plasma adiponectin was determined using radioimmunoassay. RESULTS: There was a strong positive significant correlation for adiponectin and Systolic blood pressure(SBP) (p< 0.027) and a moderate, positive significant correction for Diastolic blood pressure(DBP) (p< 0.028). A multivariate liner regression showed that plasma adiponectin could significantly predict 19% of the variance in SBP (p=0.017, and 33% for DBP (p=0.017). CONCLUSION: In conclusion, adiponectin was positively and significantly correlated to blood pressure in obese Latino adolescent youth. Future studies should investigate this relationship in a large sample of Latino adolescent youth.

Community-Acquired Methicillin-Resistant Staphylococcus Aureus Hepatic Liver Abscess.

A methicillin-resistant Staphylococcus aureus (MRSA) liver abscess is a rare infection that if not recognized, and treated early, can be fatal. There is limited literature demonstrating possible etiologies of MRSA liver abscesses, whether nosocomial or community acquired. We present a case of a 45-year-old Guyanese male with a 30 pack-year smoking history. The patient presented with both generalized abdominal pain and a productive cough on two separate occasions. Laboratory results in his second presentation revealed leukocytosis with increased alanine transaminase (ALT). Imaging revealed a multiloculated abscess in the inferior aspect of the liver, measuring 5.1 cm x 3.4 cm x 4 cm, and chest X-ray revealed developing consolidation within the right perihilar region. The patient underwent percutaneous liver drainage via pigtail catheter. Fluid cultures grew MRSA. The patient was placed on vancomycin for three weeks. On subsequent examinations, there was a resolution of leukocytosis with no drainage from the pigtail catheter. Elevations of aspartate transaminase (AST), ALT, and gamma-glutamyl transferase (GGT) were observed. Therefore, in addition to restarting vancomycin, the patient was started on ciprofloxacin for two weeks and liver function tests (LFTs) trended downwards, without recurrence of symptoms. High suspicion for liver abscess should exist in patients that present with complaints of abdominal pain and elevated LFTs when a previous source of infection has been observed. MRSA liver abscesses are rare and potentially fatal, therefore, early recognition and appropriate management is essential.
