Serum brain-derived neurotrophic factor in relation to craving and duration of abstinence in patients with heroin dependence-A case-control study.

BACKGROUND AND OBJECTIVES: Addiction is a chronic disorder that comes with emotional and financial burdens. Several neurobiological factors were correlated to opiate-use disorder which is brain-derived neurotrophic factor (BDNF). BDNF has been found to be involved in long-term potentiation of synaptic strength, a mechanism that is thought to motivate both natural adaption mechanisms as well as the development of addictive behavior. In this study, we aimed to address the relation between BDNF serum level and heroin craving and the effect of duration of abstinence on them. METHODS: A case study was conducted on 80 subjects from Kasr Al-Ainy Psychiatry and Addiction Treatment Hospital with a history of heroin dependence and were divided into two groups: Group A had 40 active heroin-dependent subjects while in Group B, 40 subjects with 1-year heroin abstinence. Severity of addiction was assessed by the addiction severity index, heroin craving was measured by Brief Substance Craving Scale and serum BDNF level was investigated using an enzyme-linked immunosorbent assay. RESULTS: The findings show that active heroin users had significantly higher serum BDNF which is associated with high heroin craving in comparison to the abstinent group. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: This study revealed a significant positive correlation between serum BDNF levels and craving in active heroin users versus 1-year abstinent subjects. It is the first study to address the relationship between craving and serum BDNF level in a 1-year abstinent participants. These findings help to determine the brain alterations associated with illness and recovery in heroin dependence.

Psychiatric and functional neuroimaging abnormalities in chronic hepatitis C virus patients: Is vasculitis a contributing factor?

BACKGROUND AND STUDY AIMS: Central nervous system (CNS) involvement in hepatitis C virus (HCV) infection has different facets such as anxiety, depression, cognitive impairment and vasculitis. We were interested in detecting subclinical CNS involvement in chronic HCV infected subjects with and without systemic vasculitis. PATIENTS AND METHODS: Nineteen patients (15 females and 4 males) with chronic HCV infection (mean age 46.5 ±â€¯7 and mean duration since diagnosis of HCV infection 4.7 ±â€¯4 years, including 6 (32%) Child-Pugh class A cirrhotic patients) and 30 age, sex and education matched healthy control subjects were studied. Thirteen patients had associated vasculitis. Patients and control subjects were assessed using the block design and comprehension subtests of Wechsler Bellevue Adult Intelligence Scale, Wechsler Memory scale (WMS), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). Brain HMPAO Single Photon Emission Computed Tomography (SPECT) was performed for HCV patients. RESULTS: Patients with HCV had lower scores on the block design test compared to control subjects (8.37 ±â€¯1.89 versus 10.37 ±â€¯1.47, p < 0.001), lower total WMS scores (43.15 ±â€¯10.49 versus 60.27 ±â€¯8.08, p < 0.001) and higher anxiety and depression scores (16.94 ±â€¯10.46 and 37.17 ±â€¯10.38 versus 10.3 ±â€¯4.67 and 28.9 ±â€¯5.99, p = 0.004 and 0.001, respectively). Total WMS were lower in HCV patients with vasculitis compared to those without vasculitis (39.14 ±â€¯9.3 versus 51.17 ±â€¯8.3, p = 0.019) while the block design and comprehension tests, BAI and BDI were not significantly different between both groups. The block design and comprehension tests, WMS, BAI and BDI were not significantly different between cirrhotic and non-cirrhotic patients. Seven patients had different patterns of cerebral hypoperfusion on SPECT, and all of them had associated vasculitis. Abnormal SPECT was associated with lower total WMS scores (35.87 ±â€¯10.8 versus 46.79 ±â€¯8.6 in those with normal SPECT, p = 0.049). CONCLUSIONS: Vasculitis may contribute to the development of neuropsychiatric involvement in HCV patients.

An examination of motives for tramadol and heroin use in an Egyptian sample.

Tramadol misuse is a significant problem in Egypt, yet little is known about tramadol users. The aim of this study is to examine the motivations for use of tramadol or heroin among patients in substance use disorder treatment in order to understand their unique treatment profiles. A cross-sectional observational study was conducted with 100 treatment-seeking men who reported either tramadol or heroin as their primary substance. Patients were recruited in 2014-2015 from inpatient and outpatient addiction treatment units in a public and private hospital in Cairo. A clinical assessment examined their motives for initiation and continuation of use of either substance based using the following categories: Negative reinforcement (Pain Avoidance), Positive reinforcement (Pleasure Seeking), Incentive salience (Craving), Stimulus-response learning (Habits), Impaired inhibitory control (Impulsivity), and Quasi-medical. Bivariate comparisons of mean scores on motive items and aggregate categories were conducted for tramadol vs. heroin groups; multivariate regression analyses controlled for demographic covariates and treatment site. A majority of the sample endorsed multiple motives for initiation and continuation of use of their primary substance. Primary heroin users were more likely to initiate use due to pain avoidance, whereas primary tramadol users were more likely to initiate use for pleasure seeking (p = 0.002). Pain avoidance was the strongest motive category for continuation of use for both groups. Craving was a stronger motivation for initiation and continuation of use among heroin patients. Patients in treatment for primary use of tramadol or heroin display unique profiles of motivations for initiation and continuation of use, which should be considered within treatment interventions.

Impact of political violence on the mental health of school children in Egypt.

BACKGROUND: Since the beginning of the Egyptian political conflict, Tahrir Square has been the epicentre of intense political violence. Students attending schools located near this square witnessed and/or directly experienced the consequences of a series of violent events. AIM: This study will investigate the presence of psychiatric symptoms in children attending these schools to explore patterns of responses according to their perceptions of the revolution on their lives, adjusted for, gender and socio-economic status. METHOD: A descriptive cross-sectional study conducted with 515 Egyptian school children attending government, experimental, and private language schools located within 1 km of Tahrir Square. To assess psychiatric symptoms in these children, a specially designed questionnaire was used to detect, depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms and impairments. RESULTS: Children attending schools near Tahrir Square showed high rates of depression, PTSD and anxiety symptoms. The risk factors identified for developing psychiatric symptoms were a negative perception of the effect of the revolution, knowing someone exposed to trauma during the events, female gender and low socio-economic class. DISCUSSION: These results highlight the need for large-scale studies to explore the consequences of ongoing political violence on children and to establish baseline data on the mental health of Egyptian children.

Role of traditional healers in the pathway to care of patients with bipolar disorder in Egypt.

BACKGROUND: A large number of mentally ill patients prefer to visit non-medical practitioners such as traditional healers because of the confidence in the system, affordability and accessibility of the service. This may lead to delay in seeking psychiatric services and has prognostic impact. AIM: To assess the rate of bipolar affective disorder (BAD) patients seeking traditional healers, the sociodemographic and clinical correlates of those patients. METHODS: We assessed 350 patients with BAD after confirmation of diagnosis with Structured Clinical Interview for DSM-IV Axis I Disorder (SCID-I) research version and assessment of functioning with Global Assessment of Functioning scale. They were assessed for percent, rate and timing of seeking traditional healers. RESULTS: In all, 40.8% sought traditional healers, with 34.9% more than four times. Of those, 62.2% were before seeking psychiatric services and 37.8% after. Lower educational level, less impairment of functioning and presence of hallucinations were significant correlates. CONCLUSION: This study shows that most of the patients suffering from mental illness prefer to approach faith healers first, which may delay entry to psychiatric care and thereby negatively impact the prognosis of BAD. This highlights the importance of mental health education and developing a positive collaborative relationship with traditional healers.

Correlates of psychiatric co-morbidity in a sample of Egyptian patients with bipolar disorder.

BACKGROUND AND OBJECTIVES: Bipolar disorder (BD) is a complex, chronic mood disorder involving repeated episodes of depression and mania/hypomania. Two thirds of patients with bipolar disorder have a comorbid psychiatric condition. This study aims to assess the prevalence of Axis I diagnosis with its socio-demographic and clinical correlates among a sample of Egyptian patients with bipolar disorder. METHODS: Out of the 400 patients who were enrolled in the study from number of governmental and private psychiatric hospitals in Cairo, Egypt, 350 patients diagnosed with bipolar affective disorders (157 females and 193 males) with age ranging from 18 to 55years were selected. Patients were assessed using the Structured Clinical Interview for DSM-IV Axis I disorder (Research Version) (SCID-I). RESULTS: Prevalence of psychiatric comorbidity among BD patients was 20.3% (71 patients) among which 63 patients (18%) had comorbid substance abuse and 8 patients (2.3%) had comorbid anxiety disorders. LIMITATIONS: The study was limited by its cross sectional design with some patients having florid symptoms during assessment, not having a well representative community sample. This might have decreased the reliability and prevalence of lifetime psychiatric comorbidity due to uncooperativeness or memory bias. The study group was composed of bipolar patients attending tertiary care service which limits the possibility of generalizing these results on different treatment settings. CONCLUSIONS: Substance abuse followed by anxiety disorders was found to be the most common psychiatric comorbidity. Family history of psychiatric disorders and substance abuse as well as current psychotic features were highly correlated with comorbidity.
