5-HT(3A) receptor antagonists have been used mainly for the treatment of nausea and vomiting. These days, the antagonists are of special interest due to their therapeutic potential to treat other diseases such as depression, psychotic disorder, drug abuse, and irritable bowel syndrome. To discover novel 5-HT(3A) receptor antagonists, we screened our in-house small molecule library, resulting in identifying the quinazolindione derivatives as potent 5-HT(3A) receptor antagonists. For the purpose of structure-activity relationship study, 24 quinazolindione analogues were biologically evaluated against 5-HT(3A) receptor. Among those, KKHT10612 shows the best antagonistic effect against 5-HT(3A) receptor with an IC(50) value of 0.8 microM which is comparable with that of the reference compound, MDL72222, and selectivity over T-type calcium channel as well.

Non-celiac gluten sensitivity (NCGS) is a syndrome characterized by intestinal and extraintestinal symptoms related to the ingestion of gluten-containing food in subjects who are not affected by either celiac disease (CD) or wheat allergy (WA). The prevalence of NCGS is not clearly defined yet. Indirect evidence suggests that NCGS is slightly more common than CD, the latter affecting around 1% of the general population. NCGS has been mostly described in adults, particularly in females in the age group of 30-50 years; however, pediatric case series have also been reported. Since NCGS may be transient, gluten tolerance needs to be reassessed over time in patients with NCGS. NCGS is characterized by symptoms that usually occur soon after gluten ingestion, disappear with gluten withdrawal, and relapse following gluten challenge within hours/days. The 'classical' presentation of NCGS is a combination of irritable bowel syndrome-like symptoms, including abdominal pain, bloating, bowel habit abnormalities (either diarrhea or constipation), and systemic manifestations such as 'foggy mind', headache, fatigue, joint and muscle pain, leg or arm numbness, dermatitis (eczema or skin rash), depression, and anemia. In recent years, several studies explored the relationship between the ingestion of gluten-containing food and the appearance of neurological and psychiatric disorders/symptoms like ataxia, peripheral neuropathy, schizophrenia, autism, depression, anxiety, and hallucinations (so-called gluten psychosis). The diagnosis of NCGS should be considered in patients with persistent intestinal and/or extraintestinal complaints showing a normal result of the CD and WA serological markers on a gluten-containing diet, usually reporting worsening of symptoms after eating gluten-rich food. NCGS should not be an exclusion diagnosis only. Unfortunately, no biomarker is sensitive and specific enough for diagnostic purposes; therefore, the diagnosis of NCGS is currently based on establishing a clear-cut cause-effect relationship between the ingestion of gluten and the appearance of symptoms by a standardized double-blind, placebo-controlled gluten challenge.

This case report illustrates the relationship between gut, hormonal, and brain function in that dietary change, mindfulness interventions, and detoxification led to resolution of disabling psychiatric symptoms. In this case, a single Caucasian female resolved her symptoms of bipolar disorder (BD) including psychotic features and suicidality, posttraumatic stress disorder symptoms from childhood torture, disordered eating, fibromyalgia, and irritable bowel syndrome through lifestyle interventions. This patient survived a severe trauma history only to develop alcohol dependence, disordered eating, and depressive symptoms, which were treated with a polypharmaceutical psychiatric approach. She was formally diagnosed with BD after being treated with antidepressants and went on to be treated with up to 15 medications in the ensuing years. Disabled by the side effects of her treatment, she worked with her treating psychiatrist to taper off of 4 medications before she learned of nutritional change through a book authored by the author. After completing 1 mo of these recommendations including dietary change, detox, and meditation, she enrolled in the author's online program and went on to resolve her symptoms, physical and psychiatric, to the extent that BD has been removed from her medical record. She has been symptom free for 1 y. This case is evidence of the potential for self-directed healing and resolution of chronic illness.

Non celiac gluten sensitivity (NCGS) is a syndrome characterized by a cohort of symptoms related to the ingestion of gluten-containing food in subjects who are not affected by celiac disease (CD) or wheat allergy. The possibility of systemic manifestations in this condition has been suggested by some reports. In most cases they are characterized by vague symptoms such as 'foggy mind', headache, fatigue, joint and muscle pain, leg or arm numbness even if more specific complaints have been described. NCGS has an immune-related background. Indeed there is a strong evidence that a selective activation of innate immunity may be the trigger for NCGS inflammatory response. The most commonly autoimmune disorders associated to NCGS are Hashimoto thyroiditis, dermatitis herpetiformis, psoriasis and rheumatologic diseases. The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported; it could be a characteristic feature that could help the diagnosis and be simultaneously managed. A possible neurological involvement has been underlined by NCGS association with gluten ataxia, gluten neuropathy and gluten encephalopathy. NCGS patients may show even psychiatric diseases such as depression, anxiety and psychosis. Finally, a link with functional disorders (irritable bowel syndrome and fibromyalgia) is a topic under discussion. In conclusion, the novelty of this matter has generated an expansion of literature data with the unavoidable consequence that some reports are often based on low levels of evidence. Therefore, only studies performed on large samples with the inclusion of control groups will be able to clearly establish whether the large information from the literature regarding extra-intestinal NCGS manifestations could be supported by evidence-based agreements.

We conducted a systematic review and a fixed-effects meta-analysis to determine whether incident adverse psychiatric events (APE) including depression, anxiety, psychosis, or suicide were associated with biologic therapy in IBD. Six randomized controlled trials and a cohort study met criteria, reporting an incidence of APE in 4,882 patients. The risk difference per 100 person-months of any APE with a biologic medication was 0.01 (95% confidence interval = 0.00-0.02). There was insufficient evidence available in randomized controlled trials to conclude that biologic therapy in IBD is associated with an increased incidence of APE.
