MTHFR gene polymorphism and age of onset of schizophrenia and bipolar disorder.

OBJECTIVE: Several studies with contradictory results from different cultures about association of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism in schizophrenia and bipolar disorders. Little is known about this association in Arab culture and Egypt. So the present study aimed to assess the association of MTHFR C677T polymorphism in bipolar disorder (BD) and schizophrenia in comparison to control group. The association between MTHFR C677T polymorphism and the age at onset in schizophrenia or BD was also studied. METHODS: Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) were used to examine the genotype and allele frequencies of MTHFR C677T polymorphism in 149 healthy subjects and 134 bipolar and 103 schizophrenia patients. RESULTS: In BD and schizophrenia, there was a higher prevalence of MTHFR C677T polymorphism than healthy subjects. Earlier age at onset was found in patients with BD, carrying one copy of the T allele or CT genotypes but not in patients with schizophrenia. CONCLUSION: The present findings suggest that the MTHFR C677T polymorphisms are likely to be associated with the risk of developing BD and schizophrenia and influence the age at onset of BD but not the age at onset of schizophrenia.

Predictors of postpartum depression in a sample of Egyptian women.

INTRODUCTION: Postpartum depression (PPD) represents a considerable health problem affecting women and their families. The aims of this study were to: (a) compare female patients with PPD to normal controls with regard to some biopsychosocial variables, (b) correlate between the severity of PPD and some clinical and biological variables, and (c) to predict some risk factors for PPD. METHOD: Sixty female patients with PPD were compared with 60 healthy postpartum females (control group). Patient and controls were subjected to: (1) a complete psychiatric and obstetric examination, (2) psychometric studies using the Edinburgh Postnatal Depression Scale, Fahmy and El-Sherbini's Social Classification Scale for Egyptian socioeconomic classification and Horowitz et al's Impact of Event Scale, (3) quantities of thyroid hormone (T3), cortisol hormone, and estrogen were assessed. RESULTS: There were high statistical differences between PPD females and controls as regard psychosocial stressors, level of (estradiol, thyroxin [T3], and cortisol), marital status, residence, parity, method of delivery, complicated puerperium, positive history of premenstrual tension syndrome and baby variables (eg, unwelcomed, with a negative attitude of parents toward the baby, underweight, female, artificially feeding, unhealthy baby). While there were moderate statistical differences in attitude toward spouse and social support and mild statistical difference in socioeconomic status between them. Severity of depression is positively highly correlated with onset of depression, psychosocial stress, levels of T3 and cortisol. However, severity of depression is negatively high when correlated with socioeconomic status. Stepwise linear regression indicated that PPD was significantly predicted by social support, socioeconomic status, feeding of baby, and prior psychiatric problems. CONCLUSION: Many factors may lead to development of PPD. These factors include some psychosocial, socioeconomic, obstetric, and hormonal variables. Early detection of these factors could help in prediction of the development of PPD.

Psychiatric morbidity among Egyptian breast cancer patients and their partners and its impact on surgical decision-making.

INTRODUCTION: Psychiatric morbidities, especially cases of anxiety and depression, are prevalent among breast cancer patients and their partners. PATIENTS AND METHODS: Fifty-four early diagnosed breast cancer patients and their partners were compared with 50 healthy couples to assess psychiatric morbidity and the impact of various factors upon patients' surgical choice. RESULTS: It was found that 18.5%, 22.2%, and 3.7% of husbands had generalized anxiety disorder, major depressive disorder, and panic disorder, respectively. It was also found that 38.8%, 29.6%, and 9.2% of the patients had major depressive disorder, generalized anxiety disorder, and panic disorder, respectively. Depression and anxiety scores were high in both partners in love-based, well-adjusted marriages, within the middle socioeconomic class, and among educated couples. Among the well-known factors related to surgical treatment choice (age, parity, tumor size, pathology, grade, lymph node status), only age and psychological morbidity (in the patients and their partners) had a significant impact on treatment choice. CONCLUSION: Patients of middle socioeconomic class, the well educated, and those in love-based marriages had a higher likelihood of suffering different types of psychological morbidities and were more likely to choose breast conservation or reconstruction than mastectomy.
