Resumption of ovulation in anovulatory women with PCOS and obesity is associated with reduction of 11ß-hydroxyandrostenedione concentrations.

STUDY QUESTION: Is resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity associated with differential changes in endocrine and metabolic parameters (weight, insulin resistance, anti-Müllerian hormone (AMH), and androgens) compared to women with PCOS who remained anovulatory? SUMMARY ANSWER: Resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity is associated with changes in serum 11ß-hydroxyandrostenedione (11OHA4) concentrations. WHAT IS KNOWN ALREADY: Lifestyle interventions have been shown to reduce clinical and biochemical hyperandrogenism in women with PCOS. Weight loss of 5-10% may reverse anovulatory status, thereby increasing natural conception rates. However, the mechanisms underlying why some women with PCOS remain anovulatory and others resume ovulation after weight loss are unclear. Reproductive characteristics at baseline and a greater degree of change in endocrine and metabolic features with lifestyle intervention may be crucial for ovulatory response. STUDY DESIGN, SIZE, DURATION: We used data and samples originating from an earlier randomized controlled trial (RCT), which examined the efficacy of a 6-month lifestyle intervention prior to infertility treatment compared to prompt infertility treatment on live birth rate in women with obesity. A total of 577 women with obesity (BMI > 29 kg/m2) were randomized between 2009 and 2012. Anovulatory women with PCOS who were allocated to the intervention arm of the original RCT (n = 95) were included in the current analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS: We defined women as having resumed ovulation (RO+) based on the following criteria: spontaneous pregnancy; or assignment to expectant management; or IUI in natural cycles as the treatment strategy after lifestyle intervention. Steroid hormones were measured using liquid chromatography tandem mass spectrometry. Generalized estimating equations with adjustment for baseline measures and interaction between group and time was used to examine differences in changes of endocrine and metabolic parameters between RO+ (n = 34) and persistently anovulatory women (RO-, n = 61) at 3 and 6 months after intervention. MAIN RESULTS AND THE ROLE OF CHANCE: At baseline, the mean ± SD age was 27.5 ± 3.6 years in the RO+ group and 27.9 ± 4.1 years in the RO- group (P = 0.65), and the mean ± SD weights were 101.2 ± 9.5 kg and 105.0 ± 14.6 kg, respectively (P = 0.13). Baseline AMH concentrations showed significant differences between RO+ and RO- women (median and interquartile range [IQR] 4.7 [3.2; 8.3] versus 7.2 [5.3; 10.8] ng/ml, respectively). Baseline androgen concentrations did not differ between the two groups. During and after lifestyle intervention, both groups showed weight loss; changes in 11OHA4 were significantly different between the RO+ and RO groups (P-value for interaction = 0.03). There was a similar trend for SHBG (interaction P-value = 0.07), and DHEA-S (interaction P-value = 0.06), with the most pronounced differences observed in the first 3 months. Other parameters, such as AMH and FAI, decreased over time but with no difference between the groups. LIMITATIONS, REASONS FOR CAUTION: No high-resolution transvaginal ultrasonography was used to confirm ovulatory status at the end of the lifestyle program. The small sample size may limit the robustness of the results. WIDER IMPLICATIONS OF THE FINDINGS: Reduction of androgen concentrations during and after lifestyle intervention is associated with recovery of ovulatory cycles. If our results are confirmed in other studies, androgen concentrations could be monitored during lifestyle intervention to provide individualized recommendations on the timing of resumption of ovulation in anovulatory women with PCOS and obesity.

Selective serotonin reuptake inhibitors for aggressive behavior in patients with dementia after head injury.

Head injury of any severity can result in acute and chronic neuropsychiatric symptoms. After head injury, aggressive behaviors can be disabling to victims and stressful to their families. When aggression is compounded by dementia, treatment can be more difficult. Psychotropic agents can attenuate aggressive behaviors associated with mental disorders. Three patients with dementia and chronic aggression after head injury responded favorably to selective serotonin reuptake inhibitors.

Seizure possibly associated with fluvoxamine.

OBJECTIVE: To inform clinicians of the possibility that seizures due to therapeutic doses of fluvoxamine may not be as rare as previously considered. CASE SUMMARY: A 49-year-old white man with schizoaffective disorder and a past history of seizures secondary to head trauma had been seizure-free for approximately 10 years. Fluvoxamine therapy was begun due to increasing obsessive-compulsive behavior. Despite receiving anticonvulsants for his mood disorder, the patient had a breakthrough seizure. There were no underlying medical conditions that might have induced this seizure. No further seizures occurred after he was placed on a higher dosage of the anticonvulsants. The obsessive-compulsive behavior improved considerably as a result of fluvoxamine treatment. DISCUSSION: The patient presented here developed a seizure with a therapeutic dosage of fluvoxamine; seizures associated with this agent have occurred more often with overdose. Multiple factors such as a prior history of seizures, head trauma, and concurrent treatment with other psychotropic agents are considered in this case report. CONCLUSIONS: Despite the relatively safe and benign adverse effect profile of the selective serotonin-reuptake inhibitors such as fluvoxamine, clinicians should be cautious about seizures as an adverse effect, especially when the patient has even a remote history of seizure or head trauma.
