Most drugs are ineffective for the long-term treatment of irritable bowel syndrome (IBS). The beneficial effects of medical treatment of IBS are poor and last for only a relative short time. Over a period of 6 months, we investigated the effectiveness of cimetropium bromide, a new antimuscarinic compound, in patients with IBS. Forty-eight patients were treated at random and in double-blind fashion with cimetropium bromide (50 mg, tid) or placebo for 6 months. Personal diary cards and monthly check-ups guaranteed the monitoring of symptoms (mainly pain). In addition, personality patterns (MHQ-CBA tests) were obtained for the patients before and after therapy, both to detect possible psychoneurotic traits and to observe the changes in these traits in relation to the changes in pain symptoms. Three patients on placebo and one on cimetropium dropped out. At the end of therapy, pain scores had decreased an average of 16% in the placebo group and 87% in the cimetropium group (p less than 0.01). Twenty patients (87%) on cimetropium versus five patients (24%) on placebo considered themselves to be globally improved (p less than 0.01). The MHQ test showed significant improvement in the anxiety score in the cimetropium group only. The CBA test confirmed a significant decrease in anxiety state (STAI-X-1) after cimetropium treatment. Eleven patients (48%) on cimetropium reported side effects (mainly dry mouth and sleepiness), but none withdrew from the study. The results of this trial indicate that long-term treatment of IBS with cimetropium bromide significantly improves symptoms and associated psychological disorders.

We present the case of a 17-year-old male who was diagnosed at birth with hereditary fructose intolerance (HFI). The patient complained of morning-time asthenia and post-prandial drowsiness despite a correct sleep pattern. The physical examination and biological check-up only showed severe vitamin C deficiency (<10 mol/l; normal range: 26-84). The patient's tiredness was attributed to this vitamin C deficiency, which is a frequent side-affect of the fructose-free diet. A change in diet associated with a supplementation in vitamin C was advised, with an increase in vegetable intake, principally avoiding carrots, onions, leaks and tinned sweet-corn. This case offers the opportunity for a review of this rare disease. Two kinds of fructose metabolism disorders (both autosomal recessive) are recognized: 1) essential fructosuria caused by a deficiency of fructokinase, which has no clinical consequence and requires no dietary treatment; 2) HFI, linked to three main mutations identified in aldolase B gene that may be confirmed by fructose breath test, intravenous fructose tolerance test, and genetic testing. In HFI, fructose ingestion generally induces gastro-intestinal (nausea and vomiting, abdominal pain, meteorism) and hypoglycemic symptoms. Fasting is well tolerated. If the condition remains undiagnosed, it leads to liver disease with hepatomegaly, proximal tubular dysfunction, and slow growth and weight gain. In conclusion, endocrinologists should be aware of this rare metabolic disease in order to provide careful follow-up, particularly important when the patient reaches adulthood. Moreover, hypoglycemia induced by fructose absorption, unexplained liver disease, irritable bowel syndrome or familial gout in an adult is suggestive of the diagnosis.

Local or village chickens are the major source of poultry products in less developed countries, but information is limited on their susceptibility or resistance to diseases. In this work, 6-week-old local Nigerian chickens, pullets and broilers were used. One day before infection the mean body weight of the broilers was more than twice that of the pullets and local chickens. The bursa: body weight (B:BW) indices of the pullets and local chickens were similar, but were significantly higher than those of broilers. Following inoculation intraocularly with pathogenic infectious bursal disease virus (IBDV) drowsiness, drop in feed and water consumption, and diarrhoea were observed among the local chickens and pullets on day 2 post inoculation (p.i.) and in the broilers on day 3 p.i. Body weight losses from 1 to 11 days p.i. were significantly higher in the local chickens and pullets than in the broilers, total mortalities being 17.6, 50.0 and 61.51% in broilers, pullets and local chickens, respectively. Necropsy showed that dehydration and proventricular haemorrhages occurred most frequent in the local chickens. The response correlated with the B:BW indices on day 14 p.i. This showed that local Nigerian chickens are more susceptible to IBD than broilers and slightly more susceptible than pullets, explaining earlier reports that mortality due to IBD was higher in pullets or light breeds of chicken than in broilers or heavy breeds.

Trimebutine, an antispasmodic drug, is used to relieve pain associated with irritable bowel syndrome, despite a lack of proven efficacy. Trimebutine has been shown to act on peripheral opioid receptors. Cases of trimebutine abuse and addiction have been reported in young adults, especially with the injectable form. Cases of serious accidental or intentional trimebutine overdose have been reported in infants and young adults, leading to neurological disorders (loss of consciousness, coma, drowsiness and convulsions) and cardiac disorders (bradycardia, ventricular tachycardia, arterial hypertension). Time to symptom onset was less than 3 hours after trimebutine intake. In practice, trimebutine is by no means a harmless drug, contrary to the impression given by the limited safety data available. Patients with pain due to irritable bowel syndrome should be informed of the adverse effects of trimebutine, and the harm-benefit balance should be reassessed in patients already taking this drug.

Fatigue is the most common extraintestinal symptom in women with irritable bowel syndrome (IBS). Genetic polymorphisms of monoamines are associated with fatigue in many chronic diseases. In this pilot exploratory study, the primary aim was to determine whether genetic polymorphisms of tryptophan hydroxylase ( TPH1/TPH2), serotonin reuptake transporter ( SERT), or catechol-O-methyltransferase ( COMT) are associated with fatigue in women with IBS. Additionally, analysis explored whether these genetic associations with fatigue would be present when controlling for abdominal pain, psychological distress, feeling stressed, and sleepiness during the day. Secondary analysis of two randomized controlled trial baseline data sets in Caucasian women with IBS ( N = 185) was conducted. Participants kept a daily diary with one dimension (i.e., severity) for each of the 26 symptoms, including fatigue, for 28 days prior to randomization. DNA samples were tested for single-nucleotide polymorphisms (SNPs) of TPH1 (four SNPs) /TPH2 (one SNP), SERT (one SNP), and COMT (one SNP). Analysis of covariance was used to examine associations of percentage of diary days with moderate to very severe symptoms with genetic polymorphisms. Only one SNP, TPH2 rs4570625, was significantly associated with fatigue ( p = .005). T-allele (low functional) carriers of TPH2 (i.e., G/T or T/T genotypes) reported a greater percentage of days with moderate to very severe fatigue than G/G homozygotes ( p = .001). Reduced synthesis of tryptophan in the central nervous system may contribute to reports of fatigue in women with IBS. Understanding genetic risk factors for fatigue may elucidate preemptive strategies to reduce fatigue in individuals with IBS.

The outbreak of the COVID-19 caused by coronavirus SARS-CoV2, is rapidly spreading worldwide. This is the first pandemic caused by a coronavirus in history. More than 150 000 confirmed cases worldwide are reported involving the SARS-CoV2, with more than 5000 COVID-19-related deaths on March 14, 2020. Fever, chills, cough, shortness of breath, generalised myalgia, malaise, drowsiness, diarrhoea, confusion, dyspnoea, and bilateral interstitial pneumonia are the common symptoms. No therapies are available, and the only way to contain the virus spread is to regularly and thoroughly clean one's hands with an alcohol-based hand rub or wash them with soap and water, to maintain at least 1 m [3 feet] distance from anyone who is coughing or sneezing, to avoid touching eyes, nose, and mouth, and to stay home if one feels unwell. No data are available on the risk of COVID-19 and outcomes in inflammatory bowel disease [IBD] patients. Outbreak restrictions can impact on the IBD care. We aim to give a viewpoint on how operationally to manage IBD patients and ensure quality of care in the current pandemic era.
