Metabolic syndrome in young adults with epilepsy

Cognition and obesity in adults with epilepsy

Introduction

Objective: to assess the occurrence of overweight/obesity in patient with epilepsy (PWEs) and to relate it to cognitive aspects and clinical variables. Methodology: the measurements of waist circumference, calf circumference, arm circumference, and the body mass index were related to the scores of the Mini-Mental State Examination and the Brief Cognitive Battery-Edu, as well as to the clinical variables of 164 PWEs, with a significance level of p < 0.05. Data were compared to a similar control group (CG) comprising 71 cases. Linear and multiple logistic regression models were used to assess factors related to cognitive aspects. Results: the mean age of the PWEs was 49.8 ± 16.6 years with a mean length of epilepsy of 22 ± 15.9 years. Overweight/obesity occurred in 106 (64.6 %) PWEs and in 42 (59.1 %) CG subjects. The PWEs had a worse performance in several cognitive functions when compared to CG subjects. In the PWEs, overweight/obesity was associated with lower educational level, older age, and cognitive impairment. Greater waist circumference, overweight, age at the first seizure, and use of polytherapy with antiseizure medications were predictive factors of memory impairment in multiple linear regression. Greater arm and calf circumference values were associated with better performance in several cognitive areas. Conclusion: the occurrence of overweight/obesity in PWEs and CG subjects was high. Cognitive impairment occurred in a high number of PWEs and was associated with overweight, greater waist circumference values, and clinical aspects of epilepsy. Better cognitive performance was associated with greater arm and calf circumference.

Increased vascular risk factors, atherosclerosis, and psychological distress among Indian adults with refractory epilepsy in comparison to well-controlled epilepsy

OBJECTIVE

Comparison of cardiovascular risk factors, atherosclerosis, and psychological distress among adults with refractory versus well-controlled epilepsy.

METHODS

The cross-sectional study consisted of two groups of 40 people each: Group I - People with well-controlled epilepsy, Group II - People with refractory epilepsy. Age- and gender-matched people of 20-50 years were recruited. People who were diabetic, smokers, hypertensive, alcoholic, pregnant, with infections, and lactating women were excluded from the study. Biochemical parameters, fasting glucose, lipid profile, fasting insulin, leptin, adiponectin, Lp[a], hsCRP, TyG INDEX, HOMA1-%S, HOMA1-IR, HOMA1-%B, QUICKI, FIRI, AIP, AC, CLTI, MLTI, CRI-I, CRI-II, and CIMT were estimated. Stress levels [PSS-10, GAD-7 & PHQ-9] were assessed based on the scoring system from the questionnaires.

RESULTS

The existence of metabolic syndrome, levels of triglycerides, TyG index, MDA, OSI, CIMT, AIP, and stress scores [PSS-10, GAD-7 & PHQ-9] were significantly higher in the refractory-epilepsy group in comparison to the well-controlled group. There were associations between LDL -C and CIMT as well as between GAD-7 and CIMT among all the study subjects. There were no significant differences in the levels of glucose homeostasis parameters, hsCRP, leptin, adiponectin, and Lp[a] between the two groups. Based on the ROC analysis, MDA [AUC = 0.853] and GAD-7 [AUC = 0.900] are useful in the differential diagnosis of the study groups.

CONCLUSION

People with refractory epilepsy had increased levels of vascular risk factors, atherosclerosis, and stress levels compared to people with well-controlled epilepsy. Suitable disease management and therapeutic approaches to address cardiovascular and psychological distress could be planned out among people with refractory epilepsy to improve their quality of life.

Obesity and metabolic syndrome in patients with epilepsy, their relation with epilepsy control

Obesity and metabolic syndrome (MetS) are commonly observed in patients with epilepsy (PWE). Obesity and MetS are not only affecting the physical fitness and quality of life of these patients, rather antiepileptic drugs (AEDs) compliance and seizure control have also been affected. The objective of this review is to search the published literature regarding the prevalence of obesity and MetS in PWE and their relation to the response to AEDs. A comprehensive search using PubMed, Cochrane Databases, and Google Scholar was performed. A supplementary citation search was also conducted by analyzing the reference lists of identified sources. The initial search revealed 364 articles of potential relevance. The studies were analyzed in detail to obtain clinical information relevant to the objectives of the review. Many observational, case control studies, randomized control trials and few review articles were included for critical appraisal and review writing. Epilepsy is associated with MetS and obesity in all age groups. AEDs and lack of exercise are the chief causes while metabolic disturbances such as adiponectin, mitochondrial dysfunction, valproic acid (VPA)-associated insulin resistance, leptin deficiency, and endocrine dysfunction are also addressable factors. Although the risk of drug-resistant epilepsy (DRE) is also higher among obese PWE, the interaction between, MetS, and its components with DRE remain to be fully investigated. Further research is required to elucidate their interplay. Appropriate and careful selection of AEDs without compromising therapeutic efficacy supplemented by lifestyle counseling for exercise and diet should be practiced to avoid weight gain and potential DRE.

Metabolic syndrome and its associated factors among epileptic patients at Dessie Comprehensive Specialized Hospital, Northeast Ethiopia; a hospital-based comparative cross-sectional study

INTRODUCTION

Metabolic syndrome is a group of metabolic risk factors which are associated with an increased risk of cardiovascular disease and type2 diabetes. Nowadays, several studies have shown that the burden of metabolic syndrome is increasing among epileptic patients, and leads to MS-associated complications, including cardiovascular disease. However, getting published documents has been limited in Ethiopia and the study area. Therefore, we aimed to analyze the magnitude and associated factors of metabolic syndrome among epileptic patients in Dessie Comprehensive Specialized Hospital in compression with respective controls.

METHODS

Hospital-based comparative cross-sectional study design was implemented from June 25 to August 20, 2021. A total of 204 participants with an equal number of cases and controls (n = 102 each) were included. The data was collected through face-to-face interviews and biochemical analyses such as fasting blood glucose and lipid profiles were done through the enzymatic technique. The magnitude of metabolic syndrome was determined using both National Cholesterol Education Program Adult Treatment Panel III and International Diabetes Federation definition criteria. The STATA version 14 was used for statistical data analysis, and a comparison of categorical and continuous variables was done with χ2 and an independent t-test, respectively. The multivariable binary logistic regression analysis was used to identify factors associated with metabolic syndrome, and variables having a P-value of <0.05 were considered statistically significant.

RESULT

The prevalence of metabolic syndrome among the epileptic group was (25.5% in National Cholesterol Education Program Adult Treatment Panel III and 23.5% in International Diabetes Federation criteria), whereas it was 13.7% in National Cholesterol Education Program Adult Treatment Panel III and 14.7% in International Diabetes Federation criteria among control groups. According to the International Diabetes Federation criteria, low physical activity (adjusted odds ratio = 4.73, 95% CI: 1.08-20.68), taking multiple antiepileptic drugs (adjusted odds ratio = 8.08, 95% CI: 1.52-42.74), having a total cholesterol level of ≥ 200 mg/dl (adjusted odds ratio = 5.81, 95%: 1.32-41.13) and body mass index (adjusted odds ratio = 1.57, 95% CI = 1.16-2.11) were significantly associated with metabolic syndrome among epileptic participants. Applying National Cholesterol Education Program Adult Treatment Panel III criteria, taking multiple antiepileptic drugs (adjusted odds ratio = 6.81, 95% CI: 1.29-35.92), having a total cholesterol level > 200 mg/dl (adjusted odds ratio = 7.37, 95% CI: 1.32-41.13) and body mass index (adjusted odds ratio = 1.53, 96% CI: 1.16-2.01) were also significantly associated.

CONCLUSION

The prevalence of metabolic syndrome among epileptic patients was higher than that of control groups and reaches statistically significant by National Cholesterol Education Program Adult Treatment Panel III. Being on multiple antiepileptic drugs, body mass index, having low physical activity and raised total cholesterol were significantly associated with metabolic syndrome among the epileptic group. Therefore, it is better to focus on controlling weight, having sufficient physical exercise, and regular monitoring of total cholesterol levels in epileptic patients.

Circulating Metabolites as Biomarkers of Disease in Patients with Mesial Temporal Lobe Epilepsy

A major challenge in the clinical management of patients with mesial temporal lobe epilepsy (MTLE) is identifying those who do not respond to antiseizure medication (ASM), allowing for the timely pursuit of alternative treatments such as epilepsy surgery. Here, we investigated changes in plasma metabolites as biomarkers of disease in patients with MTLE. Furthermore, we used the metabolomics data to gain insights into the mechanisms underlying MTLE and response to ASM. We performed an untargeted metabolomic method using magnetic resonance spectroscopy and multi- and univariate statistical analyses to compare data obtained from plasma samples of 28 patients with MTLE compared to 28 controls. The patients were further divided according to response to ASM for a supplementary and preliminary comparison: 20 patients were refractory to treatment, and eight were responsive to ASM. We only included patients using carbamazepine in combination with clobazam. We analyzed the group of patients and controls and found that the profiles of glucose (p = 0.01), saturated lipids (p = 0.0002), isoleucine (p = 0.0001), β-hydroxybutyrate (p = 0.0003), and proline (p = 0.02) were different in patients compared to controls (p < 0.05). In addition, we found some suggestive metabolites (without enough predictability) by multivariate analysis (VIP scores > 2), such as lipoproteins, lactate, glucose, unsaturated lipids, isoleucine, and proline, that might be relevant to the process of pharmacoresistance in the comparison between patients with refractory and responsive MTLE. The identified metabolites for the comparison between MTLE patients and controls were linked to different biological pathways related to cell-energy metabolism and pathways related to inflammatory processes and the modulation of neurotransmitter release and activity in MTLE. In conclusion, in addition to insights into the mechanisms underlying MTLE, our results suggest that plasma metabolites may be used as disease biomarkers. These findings warrant further studies exploring the clinical use of metabolites to assist in decision-making when treating patients with MTLE.

Exploring the mechanisms of action of the antidepressant effect of the ketogenic diet

The ketogenic diet (KD) is characterized by a diet ratio of 4:1 fat to non-fat energy sources. For decades KD has been successfully used to control seizures in epilepsy patients. Investigations into its mechanism of action suggest that it may have an effect on the metabolic, nervous, immune, and digestive systems. In this review, we postulate that KD may also improve depressive symptoms - for that, we highlight the similarities between depression and epilepsy, describe the extent to which body systems involved in both conditions are affected by the KD, and ultimately hypothesize how KD could improve MDD outcomes. Research into animal models and human patients have reported that KD can increase mitochondrial biogenesis and increase cellular resistance to oxidative stress both at the mitochondrial and genetic levels. Its effect on neurotransmitters alters cell-to-cell communication in the brain and may decrease hyperexcitability by increasing Gamma Aminobutyric Acid (GABA) and decreasing excitatory neurotransmitter levels. Its anti-inflammatory effects are mediated by decreasing chemo- and cytokine levels, including TNF-alpha and IL-1 levels. Finally, KD can alter gut microbiota (GM). Certain strains of microbiota predominate in major depressive disorder (MDD) when compared to healthy individuals. Recent evidence points to Bacteroidetes as a potential treatment predictor as it seems to increase in KD treatment responders for epilepsy. Each of these observations contributes to the presumed modulatory effects of KD on mood and supports its potential role as antidepressant.

Atherogenic Risk Factors among Young Indian Adults with Epilepsy on Treatment with Phenytoin: Need for Novel Therapeutic Strategies

Background

Risk for the development of coronary heart disease and diabetes is found to be more among people with epilepsy especially when on treatment. Redox imbalance contributes to this risk especially in India as it is the diabetic capital of the world with higher prevalence of inflammation.

Objectives

The aim of this study was to evaluate atherogenic risk factors; dyslipidemia, oxidative stress, and systemic inflammation among young Indian adults with epilepsy on treatment with Phenytoin.

Material and Methods

Three groups of age and gender-matched young subjects were recruited. Group 1-Healthy control subjects, Group 2- Newly diagnosed epileptic young adults with recent epileptic seizures, Group 3- Epileptic adults on treatment with Phenytoin for more than 6 months were recruited.

Results

Dyslipidemia was found among the newly diagnosed epileptic subjects in comparison to healthy subjects. The LDL-cholesterol further increased, and HDL-cholesterol further decreased in the third group treated with Phenytoin. Body mass index of these treated epileptic subjects was more in comparison to healthy control. Low-grade inflammation as assessed by hsCRP and oxidative stress were significantly higher among the newly diagnosed epileptic subjects when compared to the healthy controls which further increased on treatment with phenytoin. We found dyslipidemia, oxidative stress, and low-grade inflammation among newly diagnosed epileptic subjects which further increased on treatment with Phenytoin for more than 6 months.

Conclusion

From this study, we conclude that dyslipidemia, oxidative stress and low-grade inflammation are identified among the newly diagnosed young adult Indian epileptic patients. Phenytoin treatment further augmented these complications.

Zonisamide Therapy Reduces Metabolic Consequences and Diminishes Nonalcoholic Fatty Liver Disease in Patients with Epilepsy

Antiepileptic drugs that can reduce aberrant metabolism are beneficial for patients. Zonisamide (ZNS) is a chemical with antiepileptic and antioxidant activities. Here, we evaluate the efficacy of ZNS therapy on reducing obesity and decreasing risks of vascular diseases and hepatic steatosis. Clinical and metabolic indicators including body weight, body mass index (BMI), serum lipid profiles, glycated hemoglobin (HbA1c), homocysteine, and an inflammatory marker, high-sensitivity C-reactive protein (hs-CRP), were assessed at baseline and at the end of 12 and 24 weeks of treatment. Nonalcoholic fatty liver disease was evaluated using the hepatic steatosis index (HSI). A body weight reduction of ≥5% was observed in 24.6% and 32.8% of patients after 12 and 24 weeks of ZNS treatment, respectively. After adjusting for age, sex, time, and the corresponding dependent variable at baseline, the generalized estimating equation analysis revealed that the body weight, BMI, serum levels of HbA1c, triglycerides, hs-CRP, and the index for HSI were significantly declined. These results suggest that ZNS provides benefits in patients with obesity and metabolic syndrome at high vascular risk.

Impact of predictive, preventive and precision medicine strategies in epilepsy

Over the last decade, advances in genetics, neuroimaging and EEG have enabled the aetiology of epilepsy to be identified earlier in the disease course than ever before. At the same time, progress in the study of experimental models of epilepsy has provided a better understanding of the mechanisms underlying the condition and has enabled the identification of therapies that target specific aetiologies. We are now witnessing the impact of these advances in our daily clinical practice. Thus, now is the time for a paradigm shift in epilepsy treatment from a reactive attitude, treating patients after the onset of epilepsy and the initiation of seizures, to a proactive attitude that is more broadly integrated into a 'P4 medicine' approach. This P4 approach, which is personalized, predictive, preventive and participatory, puts patients at the centre of their own care and, ultimately, aims to prevent the onset of epilepsy. This aim will be achieved by adapting epilepsy treatments not only to a given syndrome but also to a given patient and moving from the usual anti-seizure treatments to personalized treatments designed to target specific aetiologies. In this Review, we present the current state of this ongoing revolution, emphasizing the impact on clinical practice.

Metabolic syndrome and obstructive sleep apnea syndrome among patients with epilepsy on monotherapy

OBJECTIVES

The study aimed to determine the frequency of metabolic syndrome (MetS) and obstructive sleep apnea syndrome (OSAS) in patients with epilepsy receiving monotherapy and the relationship between these syndromes and antiepileptic drugs (AEDs).

METHODS

Two hundred and ninety-seven patients with epilepsy between the ages of 18-65 years receiving monotherapy for at least one year and 50 healthy participants were enrolled. Body mass indices and waist circumferences were measured. Serum fasting glucose levels, high-density lipoprotein (HDL), low density lipoprotein (LDL), total cholesterol (TC), triglyceride, and serum AED concentrations were noted. The frequency of MetS in patients with epilepsy was calculated. The snoring, tiredness, observed apnea, high blood pressure, body mass index, age, neck circumference, and male gender (STOP-Bang) questionnaire was used to determine the risk of OSAS. The relationship between these two syndromes and seizure type, disease duration, AED dosage, and treatment duration was analyzed.

RESULTS

Metabolic syndrome was more frequent in patients with epilepsy compared with healthy participants (32.6% vs. 12.0%), and it was diagnosed in 37.8% of patients receiving valproic acid (VPA), 36.1% of patients receiving carbamazepine (CBZ), 34.9% of patients receiving oxcarbazepine (OXC), and 30.5% of patients on levetiracetam (LEV). There was a positive correlation between VPA treatment duration and MetS existence (p < 0.05). However, MetS frequency did not change because of seizure type, disease duration, or AED dosages in patients with epilepsy receiving monotherapy. The risk for OSAS was higher in patients with epilepsy compared with healthy participants (24.6% vs. 12%), and it was calculated high in 27.7% of patients receiving CBZ, 32.2% of patients receiving LEV, and 30.2% of patients receiving OXC. The OSAS risk was higher in patients who have focal seizures than generalized seizures (p = 0.044). There was no relationship between OSAS risk and duration of epilepsy, duration of treatment, drug doses, and serum drug levels (p > 0.05).

CONCLUSION

Higher frequency of MetS and OSAS risk should be kept in mind on clinical follow-up of patients with epilepsy receiving monotherapy.

Evaluation of factors influencing obesity and the effect of a 12-week home-based exercise program in people with epilepsy - Randomized control trial

BACKGROUND

Association of obesity, quality of life (QoL), and physical fitness in people with epilepsy (PWE) is rarely reported. We evaluate the effect of a 12-week home-based exercise program on weight reduction and physical capacity in PWE.

METHODS

In 173 PWE, physical fitness was assessed by using six-minute walk test (6MWT) and one-minute step test. Self-reported QoL data was collected using a 12-Item Short Form Survey (SF-12) questionnaire; further physical (PCS) and mental (MCS) component scores were derived. Effect of exercise was evaluated using randomized study of 110 PWE, divided into control and exercise groups of 55 each.

RESULTS

At baseline, mean age of study population was 25.85 ± 9.62 years with 77 (44.5%) women. Average body mass index (BMI) was 29.33 ± 6.17 kg/m². Mean PCS and MCS were 45.95 ± 7.92 and 45.72 ± 10.40 respectively. In 124 (71.7%) PWE with obesity, while high-density lipoprotein (HDL-C) (46.10 ± 12.32 vs. 39.30 ± 10.39 mg/dL; p < .001) was lower, low-density lipoprotein (LDL-C) (101.60 ± 37.51 vs. 113.89 ± 32.65 mg/dL; p = .035) was high. Both the randomized groups were comparable for type and number of antiepileptic drugs (AEDs) used. At 12-week follow-up, PWE in the exercise group reduced 7.65 ± 5.62 kg while control group gained an average of 4.01 ± 4.74 kg (p < .001). Distance walked in 6MWT (293.07 ± 118.73 vs. 464.29 ± 55.33 m; p = .007) and PCS (48.59 ± 8.57 vs. 52.62 ± 4.03; p = .006) were higher in exercise group whereas MCS did not differ between the groups. None of the participants reported seizure during the 12-week follow-up period.

CONCLUSION

People with epilepsy have low PCS and MCS scores; PWE with obesity have altered metabolic profile when compared to PWE without obesity. A 12-week, home-based exercise program significantly reduces weight and improves physical capacity, irrespective of AEDs used. Trials with larger sample size and longer follow-up are required to validate our findings.

Metabolic syndrome in people with epilepsy

BACKGROUND

Little is known about the association of metabolic syndrome (MetS) and quality of life (QoL) in people with epilepsy (PWE). We evaluate the trends of MetS in PWE across various age groups. We also evaluate the association of MetS and QoL in PWE.

METHODS

Clinical and seizure data were collected in 173 people with controlled epilepsy. Physical fitness was assessed by using the six-minute walk test and one-minute step test. Self-reported SF-12 questionnaire, was used to derive physical (PCS) and mental (MCS) component scores.

RESULTS

The average age of the study population was 25.85 ± 9.62 years, and MetS was observed in 91 (52.6%). Obesity was seen in 153 (88.4%). Average distance walked in the six-minute walk test was 385.55 ± 71.52 m. Mean PCS and MCS were 45.95 ± 7.92 and 45.72 ± 10.40, respectively. More number of women had MetS (47.6% vs. 62.6%; p = 0.049) and women in the study population had lower high-density lipoprotein (HDL)-C (44.34 ± 11.60 vs. 38.65 ± 10.13 mm Hg; p < 0.001). Except for the variables that define MetS, none of the clinical characteristics were associated with MetS. Across age groups, prevalence of MetS was consistently at 50.0% although prevalence of hypertension showed a linear increase with age. While low HDL-C was seen highest (61.5%) in ≤20 years age, impaired fasting blood sugar (FBS) was highest in PWE aged >40 years.

CONCLUSION

Metabolic syndrome is seen in more than half of PWE, and this increased prevalence is not associated with the number of antiepileptic medicines. While prevalence of MetS was stable at 50.0% across all age groups, components of MetS have varying prevalence across age groups hence, suggesting their varied contribution across age groups.

Repurposing of sodium valproate in colon cancer associated with diabetes mellitus: Role of HDAC inhibition

BACKGROUND AND PURPOSE

Diabetic patients are at greater risk for colon cancer. Histone deacetylases (HDACs) serve as common target for both. The key objective of the study was to evaluate the effect of sodium valproate in type 2 diabetes mellitus associated colon cancer.

EXPERIMENTAL APPROACH

High fat diet and streptozotocin were used to induce type 2 diabetes. Following this, after diabetes confirmation, colon cancer was induced using 1,2 dimethylhydrazine (25 mg/kg, s.c.) once weekly from 7th week to 20th weeks. Sodium valproate (200 mg/kg) treatment was given from 20th to 24th week. At the end of 24 weeks, several enzymatic and biochemical parameters, were estimated. MTT, clonogenic and scratch wound healing assay were carried out in HCT-15 cell line.

KEY RESULTS

Hyperglycemia, hyperinsulinemia, increase in cytokines (TNF-α and IL-1β) and carcinoembryonic antigen and presence of proliferating cells was seen in disease control animals which was prevented by sodium valproate treatment. Overexpression of relative HDAC2 mRNA levels was found in diseased control animals, which was reduced by sodium valproate treatment. IC₅₀ of sodium valproate was found to be 3.40 mM and 3.73 mM at 48 h and 72 h respectively on HCT-15 cell line. Sodium valproate also dose dependently prevented colony formation and cell migration.

CONCLUSION AND IMPLICATIONS

Sodium valproate can be considered for repurposing in colon cancer associated with diabetes mellitus.

Diagnostic Yield and Accuracy of Different Metabolic Syndrome Criteria in Adult Patients with Epilepsy

Introduction

Metabolic syndrome (MetS) is an emergent problem among patients with epilepsy. Here, we evaluate and compare the diagnostic yield and accuracy of different MetS criteria among adult patients with epilepsy to further explore the best strategy for diagnosis of MetS among patients with epilepsy.

Materials and methods

Ninety-five epileptic adults from a tertiary epilepsy reference center were prospectively recruited over 22 weeks in a cross-sectional study. MetS was defined according to five international criteria used for the diagnosis of the condition [ATP3, American Association of Clinical Endocrinologists (AACE), International Diabetes Federation (IDF), AHA/NHLBI, and harmonized criteria]. Sensitivity, specificity, positive and negative predictive values (NPVs), and area under the receiver operating characteristic curve (ROC) curve were estimated for each criterion.

Results

In our sample, adult patients with epilepsy showed a high prevalence of obesity, hypertension, and diabetes. However, the prevalence of MetS was significantly different according to each criterion used, ranging from 33.7%, as defined by AACE, to 49.4%, as defined by the harmonized criteria (p < 0.005). IDF criteria showed the highest sensitivity [S = 95.5% (95% CI 84.5–99.4), p < 0.05] and AACE criteria showed the lowest sensitivity and NPV [S = 68.2% (95% CI 52.4–81.4), p < 0.05; NPV = 75.8% (95% CI 62.3–86.1), p < 0.05]. ROC curve for all criteria studied showed that area under curve (AUC) for IDF criterion was 0.966, and it was not different from AUC of harmonized criterion (p = 0.092) that was used as reference. On the other hand, the use of the other three criteria for MetS resulted in significantly lower performance, with AUC for AHA/NHLBI = 0.920 (p = 0.0147), NCEP/ATP3 = 0.898 (p = 0.0067), AACE = 0.830 (p = 0.00059).

Conclusion

Our findings suggest that MetS might be highly prevalent among adult patients with epilepsy. Despite significant variations in the yield of different criteria, the harmonized definition produced the highest prevalence rates and perhaps should be preferred. Correct evaluation of these patients might improve the rates of detection of MetS and foster primary prevention of cardiovascular events in this population.

Coronary heart disease risk in patients with schizophrenia: a Lebanese cross-sectional study

Background:

Coronary heart disease (CHD) is a leading cause of premature death in patients with schizophrenia. CHD risk in Lebanese patients with schizophrenia remains unknown.

Objectives:

To (i) evaluate CHD risk of patients with schizophrenia in Lebanon; and (ii) detect the modifiable and non-modifiable factors affecting this risk.

Methods:

Cross-sectional study of 329 patients with schizophrenia aged 20–75 years. Ten-year hard CHD risk was calculated using the Framingham risk score. A logistic regression was conducted taking the dichotomous hard CHD (<10% and ≥10%) as the dependent variable.

Results:

Ten-year hard CHD risk was low (<10%) in 60.8% of patients, intermediate (10–20%) in 31.6%, and high (>20%) in 7.6%. Multivariate analysis showed that the mean 10-year hard CHD risk was 8.76±6.92 (10.82±6.83 in men and 3.18±2.90 in women). Ten-year hard CHD risk was higher in patients with the metabolic syndrome (odds ratio [OR] 2.67, confidence interval [CI] 1.54–4.64), a longer duration of schizophrenia (OR 1.03, CI 1.01–1.05), a history of other medical illnesses (OR 2.02, CI 1.18–3.47), and in those participating in art therapy (OR 2.13, CI 1.25–3.64) or therapeutic education (OR 1.93, CI 0.93–4.01). Ten-year hard CHD risk was lower in patients receiving risperidone (OR 0.23, CI 0.08–0.68), any anti-epileptic (OR 0.41, CI 0.24–0.73), or any benzodiazepine (OR 0.33, CI 0.17–0.66) medication.

Conclusion:

CHD is prevalent in patients with schizophrenia in Lebanon. Physicians are recommended to monitor the components of the metabolic syndrome to identify patients with increased risk of cardiovascular diseases.
