The treatment with thiopurines and anti-TNF-α drugs does not seem to increase the risk of complications during pregnancy and does seem to be safe for the newborn.

We investigated left ventricular diastolic dysfunction (LVDD) and its relationship with circulatory function and prognosis in cirrhosis with portal hypertension and normal creatinine. Conventional and tissue Doppler (TDI) echocardiography, systemic and hepatic hemodynamics, and the activity of endogenous vasoactive systems (AEVS) were measured prospectively in 80 patients. Plasma renin activity (PRA; >4 ng/mL/hour) was used as a surrogate of effective arterial blood volume. Patients were followed up for 12 months. Thirty-seven patients had LVDD (19 with grade 1 and 18 with grade 2). Left ventricular hypertrophy, left atrial volume, AEVS, and natriuretic peptide levels were significantly greater in patients with LVDD than without LVDD. Patients with grade 2 LVDD, compared to grade 1 LVDD and without LVDD, had significantly lower mean arterial pressure and higher Model for End-Stage Liver Disease (MELD) score, E-wave transmitral/early diastolic mitral annular velocity (E/e' ratio), cardiopulmonary pressures, PRA, and natriuretic peptide levels. Systolic and cardiac chronotropic function were significantly lower in patients with grade 2 LVDD than without LVDD. LVDD was more frequent in patients with ascites and increased PRA than patients without ascites or with ascites but normal PRA. Fourteen patients with LVDD developed hepatorenal syndrome (HRS) type 1 on follow-up. Survival was different according to degree of LVDD (without LVDD: 95%; grade 1 LVDD: 79%; grade 2 LVDD: 39%; P < 0.001). Independent predictive factors of mortality were MELD score and E/e' ratio. Conclusion: LVDD occurs simultaneously with other changes in cardiac structure and function and is associated with an impairment of effective arterial blood volume. LVDD is a sensitive marker of advanced cirrhosis, type 1 HRS development, and mortality. (HEPATOLOGY 2013;58:1732-1741 C irrhosis is associated with a specific subclinical cardiomyopathy 1-4 characterized by diminished systolic responsiveness to stress stimuli, 5,6 impaired diastolic relaxation, 7,8 electrophysiological abnormalities, 9 and enlargement and hypertrophy of cardiac chambers, 10,11 all in the absence of known cardiac disease. However, evidence suggests that patients with cirrhosis display primarily left ventricular diastolic dysfunction (LVDD) with normal systolic function at rest. 7Abbreviations: 2D, two-dimensional; A, atrial wave-filling peak; ALDO, plasma concentrations of aldosterone; ANF, atrial natriuretic factor; ASE, the American Society of Echocardiography; AUC, area under the curve; BNP, brain natriuretic peptide; CI, confidence interval; CO, cardiac output; DT, deceleration time; E, E-wave transmitral peak early filling; e 0 , early diastolic mitral annular velocity; E/A, early diastolic mitral inflow velocity/late diastolic; E/e 0 ratio, E-wave transmitral/early diastolic mitral annular velocity; FHVP, free hepatic venous

The incidence rate of inflammatory bowel disease relapse after anti-TNF discontinuation is relevant. Some predictive factors of relapse after anti-TNF withdrawal have been identified. Retreatment with the same anti-TNF drug was effective and safe.

Cytomegalovirus (CMV) infection is common in humans. The virus then enters a "latency phase" and can reactivate to different stimuli such as immunosuppression. The clinical significance of CMV infection in inflammatory bowel disease is different in Crohn's disease (CD) and ulcerative colitis (UC). CMV does not interfere in the clinical course of CD. However, CMV reactivation is frequent in severe or steroid-resistant UC. It is not known whether the virus exacerbates the disease or simply appears as a bystander of a severe disease. Different methods are used to diagnose CMV colitis. Diagnosis is classically based on histopathological identification of viral-infected cells or CMV antigens in biopsied tissues using haematoxylin-eosin or immunohistochemistry, other tests on blood or tissue samples are currently being investigated. Polymerase chain reaction performed in colonic mucosa has a high sensitivity and a positive result could be associated with a worse prognosis disease; further studies are needed to determine the most appropriate strategy with positive CMV-DNA in colonic mucosa. Specific endoscopic features have not been described in active UC and CMV infection. CMV colitis is usually treated with ganciclovir for several weeks, there are different opinions about whether or not to stop immunosuppressive therapy. Other antiviral drugs may be used. Multicenter controlled studies would needed to determine which subgroup of UC patients would benefit from early antiviral treatment.
