The results suggest that MHE and a reduction in appetite are associated with deterioration in HRQL in patients with decompensated cirrhosis.

Chronic constipation is a common health problem that significantly affects the quality of life of patients and impacts in terms of costs; current treatments based on fiber and laxatives cause dissatisfaction to doctors and patients in more than half of the cases. New drugs are now available or in very advanced stages of research, with different and innovative mechanisms of action as prucalopride, lubiprostone, and linaclotide. Prucalopride an enterokinetic, is a selective high-affinity 5-hydroxytryptamine (5-HT)4 receptor agonist of serotonin that increases the peristaltic reflex and the colonic contractions; lubiprostone, a type 2 chlorine channel activator, or linaclotide, a guanylate cyclase-C agonist of enterocytes, both prosecretory agents, stimulate the secretion of fluid within the intestinal lumen. In general, these promising drugs have proven efficacy and safety as a specific therapeutic option in patients with chronic constipation. Yet the solution might not be sufficient for everybody and still without the ideal drug that might be useful in all cases, the pharmacological revolution for colonic motility disorders has arrived.

Pneumocystis jirovecii pneumonia (PCP) is a potential complication of immunosuppression. Crohn's disease (CD) is an immune granulomatous disorder characterized by transmural inflammation that can affect any part of the gastrointestinal tract. Its treatment is based on steroids and immunosuppressants but in non-responders, biologic compounds such as anti-tumor necrosis factor alpha (TNF) antibodies have been used. Neutralization of TNF causes a decrease in the inflammatory response but increases susceptibility to opportunistic infections such as fungal infections. We report a young male with chronic diarrhea, fever and weight loss who was diagnosed with CD and began conventional treatment with immunosuppressants, but due to lack of response after several weeks, biologic therapy with adalimumab was initiated. Seven weeks later he developed persistent fever and upper respiratory symptoms. After chest CT, bronchoscopy and bronchial lavage, P. jirovecii was identified by silver staining and confirmed by immunofluorescence. To our knowledge this is the second case of pneumocystosis associated with the use of adalimumab in CD and the first reported Mexican case confirmed by microbiological and immunological studies in this setting.
