Quetiapine in combination with citalopram in patients with unipolar psychotic depression

This 6-week, open-label, multicenter study evaluated the efficacy and safety of quetiapine in combination with citalopram in adult patients (n=25) with ICD-10/DSM-IV unipolar psychotic depression. The primary endpoint was change from baseline to Week 6 in the Hamilton Depression Rating Scale (HAM-D-21) score. Secondary endpoints were change from baseline to Week 6 in the Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Impression (CGI) Scale scores. Spontaneously reported adverse events (AEs), the Simpson Angus Scale (SAS), and the Udvalg for Kliniske Undersogelser (UKU) side effects rating scale scores were recorded. Patients' average age was 51.4 years and baseline weight was 72.6 kg. Quetiapine (50-750 mg/day, mean dose+/-SD: 303+/-118 mg/day), in combination with citalopram (20-60 mg/day, mean dose+/-SD: 34+/-12 mg/day), provided significant improvements in depression. Mean (+/- SD) HAM-D-21 was reduced to 13.25+/-10.87 at Week 6 from a baseline value of 31.21+/-5.18. Significant improvement of psychotic symptoms (mean+/-SD) was indicated by the decrease from baseline (59.25+/-6.60) to Week 6 (35.25+/-15.60) in BPRS scores. No serious AEs occurred. The mean change in weight was +2.1 kg. Mean (+/- SD) weight at visit 1 was 72.72 (+/-16.34) kg and mean (SD) weight at visit 4 was 74.79 (+/-18.69) kg. Quetiapine in combination with citalopram appears to be effective and is well tolerated in the treatment of unipolar psychotic depression. Further studies of larger, double-blind, parallel-group design are warranted to confirm these findings.     

Fabry disease in patients with migraine with aura

Anderson-Fabry disease (AFD) is an X-linked recessive lysosomal disease caused by alpha-galactosidase A (alpha-gal) deficiency, causing progressive glycosphingolipid storage in various organ systems. Headache is a frequent symptom. Cerebral magnetic resonance imaging (MRI) often shows multiple white matter lesions (WML), like those seen in patients affected by migraine, in particular with aura (MA). To our knowledge, there are no reports about the prevalence of AFD in patients with MA. The objective of the study was to determine AFD prevalence, as assessed by alpha-gal activity and genetic tests, in MA patients. We evaluated 73 consecutive patients followed by the Headache Centre of our Department with a diagnosis of MA. They were screened for migraine characteristics and cerebrovascular risk factors. Gaseous contrast transcranial Doppler was used to diagnose right-to-left shunt and MRI to detect WML. All patients underwent blood test to evaluate peripheral alpha-gal activity and to identify alpha-gal gene mutations. Of 73 consecutive screened subjects (59 females, 14 males; mean age 38.3 ± 11.8 years), the known GLA pathologic mutation p.[Asp313Tyr] was found in a 38-year-old woman, with a history of MA, deep venous thrombosis and abdominal pain. Cerebral MRI showed small WML. This is the first study reporting AFD prevalence in a cohort of MA patients. We found a relatively high prevalence (about 1.37%) among the examined patients, even if this finding needs to be confirmed in a larger sample. Despite this high prevalence, it seems not necessary to screen systematically all MA patients for AFD, but since it is a treatable genetic disorder, it is worthwhile to consider it for the subgroup of patients presenting WML and other typical AFD symptoms.
