The relation between body fat distribution and cardiovascular risk factors in patients with schizophrenia: a cross-sectional pilot study.

BACKGROUND: Obesity has recently become a concern for physicians treating schizophrenic patients. Obesity is associated with hypertension, dyslipidemia, and diabetes mellitus. In this pilot study, we investigate which anthropometric measurement, body mass index or waist circumference, is a better predictor of cardiovascular risk factors in patients with schizophrenia. METHOD: This cross-sectional study, conducted from January 2001 to January 2002, examined body fat distribution and its relation to cardiovascular risk factors in 62 patients with schizophrenia (DSM-IV) recruited from an outpatient psychiatric clinic. RESULTS: Chi-square analysis revealed that an increased waist circumference was associated with dyslipidemia (p < .01), hypertension (p < .05), and abnormal serum glucose (p < .05), whereas an increased body mass index was only associated with dyslipidemia (p < .05). In logistic regression analysis, after controlling for age, gender, race, ethnicity, smoking, and body mass index, increased waist circumference remained significantly associated with dyslipidemia (odds ratio = 2.08, 95% CI = 1.01 to 1.15, p < .05) and hypertension (odds ratio = 2.05, 95% CI = 1.02 to 1.17, p < .05). CONCLUSIONS: Waist circumference revealed a stronger correlation than body mass index to cardiovascular risk factors in patients with schizophrenia. We propose the measurement of waist circumference as a screening tool for cardiovascular risk factors in this population. Waist circumference measurement can provide an opportunity for primary prevention of coronary heart disease and diabetes mellitus in patients with schizophrenia.

Prevalence of Metabolic Syndrome in Hispanic and Non-Hispanic Patients With Schizophrenia.

BACKGROUND: Metabolic syndrome, a constellation of truncal obesity, dyslipidemia, disturbed insulin and glucose metabolism, and hypertension, is associated with the development of diabetes mellitus and coronary heart disease. However, the prevalence of metabolic syndrome in Hispanic patients with schizophrenia and whether they differ from comparable non-Hispanic patients is uncertain. METHOD: This cross-sectional study, conducted from January 2002 to May 2002, included 48 patients with schizophrenia who were recruited from an outpatient psychiatric clinic. Metabolic syndrome was defined using the criteria of the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. RESULTS: The prevalence of metabolic syndrome was 63% in all patients with schizophrenia. The metabolic syndrome was present in 41% of non-Hispanic patients and in 74% of Hispanic patients with schizophrenia. Metabolic syndrome was present in 70% of Cuban Americans and 88% of other Hispanic subgroups with schizophrenia. Metabolic syndrome was associated with waist circumference (p <.05) and high-density lipoprotein cholesterol (p <.05) in logistic regression analysis. CONCLUSIONS: These data suggest that schizophrenic patients have a 3-fold greater risk to develop metabolic syndrome than the general population. Hispanic schizophrenic patients have a significantly greater prevalence of metabolic syndrome than non-Hispanic schizophrenic patients (p <.05). An increased waist circumference is the strongest clinical correlate with metabolic syndrome in schizophrenic patients.

Sensory function and albumin excretion according to diagnostic criteria for diabetes.

OBJECTIVE: The purpose of this study was to examine sensory function and albumin excretion according to categories of glucose tolerance in individuals undergoing screening for diabetes. RESEARCH DESIGN AND METHODS: Sensory function and albumin excretion measurements were obtained in 636 individuals at the time of screening for diabetes according to American Diabetes Association glucose tolerance criteria. Sensory thresholds were measured by forced-choice techniques. Albumin-to-creatinine ratios were calculated from spot urine samples. RESULTS: Of 90 individuals whose glucose levels were in the range for diabetes, 65 had fasting glucose values >or=126 mg/dl, whereas 25 had 2-h glucose values >or=200 mg/dl, with fasting glucose values <126 mg/dl. In covariance analyses, those with fasting glucose levels >or=126 mg/dl had higher vibration (P < 0.01) and thermal (P < 0.05 for cool and warm) thresholds than those with normal glucose tolerance. This pattern was also evident for albumin-to-creatinine ratios (P < 0.001). In contrast, those with 2-h glucose values >or=200 mg/dl and fasting glucose values <126 mg/dl had sensory threshold and albumin-to-creatinine ratio values similar to those of the normal group. Individuals with fasting glucose levels >or=126 mg/dl had higher vibration threshold and albumin-to-creatinine ratio values (<0.05 and <0.01, respectively) than those with levels <126 mg/dl. CONCLUSIONS: Sensory threshold and albumin excretion values already tend to be greater than normal at screening in individuals with fasting glucose levels >or=126 mg/dl, but not in those with levels <126 mg/dl. A reliance on fasting glucose levels >or=126 mg/dl for screening might not be sufficient for early intervention and the optimal prevention of diabetes complications.

Citalopram treatment of major depressive disorder in Hispanic HIV and AIDS patients: a prospective study.

Fourteen Hispanic and six non-Hispanic outpatients with HIV-spectrum illness and major depressive disorder were enrolled in a 6-week, open-label, flexible-dose study of citalopram (dose range=10-40 mg/day). The depressive symptoms of 50% of the 14 patients who completed the study responded to citalopram (mean dose=34 mg/day). The treatment response rate, effective citalopram dose, total number of reported adverse events, and attrition rate did not differ between the ethnic groups. Two patients discontinued because of adverse events (rash, nausea), and four patients discontinued because of noncompliance with the protocol. The findings suggest that citalopram is an effective and well-tolerated antidepressant for Hispanic and non-Hispanic HIV-infected patients.

A prospective trial of sustained-release bupropion for depression in HIV-seropositive and AIDS patients.

To date, the authors know of no prospective studies of sustained-release bupropion in depressed HIV-seropositive patients. The purpose of this study was to evaluate the efficacy and tolerability of sustained-release bupropion in 20 depressed HIV-positive adult outpatients. Twenty outpatients with HIV spectrum illness, a DSM-IV-diagnosed major depressive disorder confirmed with the Structured Clinical Interview for DSM-IV, and Mini-Mental State Examination scores >20 were recruited into a 6-week, open-label, flexible-dose study of sustained-release bupropion (100-300 mg/day). Twelve patients (60%) responded to sustained-release bupropion at a mean dose of 265 mg/day. Five patients (25%) discontinued study participation secondary to adverse events. Preliminary findings suggest that sustained-release bupropion is effective for the treatment of depression in HIV-positive patients, regardless of HIV clinical staging. Furthermore, it appears to be well tolerated in patients with AIDS-related medical conditions.
