Combination of Model for End-Stage Liver Disease (MELD) and Sarcopenia predicts mortality after transjugular intrahepatic portosystemic shunt (TIPS)

TIPS is the most effective treatment for portal hypertension. Patient selection remains important to achieving optimal post-TIPS outcomes. The study evaluates 1-year mortality factors in cirrhotic patients receiving TIPS.

METHODS

87 cirrhotic patients received a TIPS between 2015 - 2021. Predictors of 1-year and overall mortality were assessed by estimating cumulative incidence functions and Grey's test to adjust for liver transplantation as a risk competing with mortality. Variables with p < 0.05 were checked for collinearity and included in the multivariate Cox proportional hazards model. Model discrimination was evaluated by calculating the area under the ROC curve.

RESULTS

87 patients were included (68% men; 22% ≥70 years). ALD was the primary cirrhosis cause. Most patients were Child-Pugh class B, MELD-Na score was 13.6 ± 6.0 points. The most frequent indication for TIPS was bleeding (51.7%), followed by refractory ascites (42.5%). The variables positively associated with mortality in univariate analysis were ascites, clinically overt sarcopenia and MELD-Na score, while ongoing nutritional supplementation improved survival. In the multivariate analysis, only clinically overt sarcopenia and MELD-Na score remained independently associated with mortality. A MELD-Na/sarcopenia model demonstrated a good discrimination, AUROC: 0.86 (95% CI 0.77 - 0.95).

CONCLUSION

MELD-Na score, and sarcopenia were significantly associated with 1-year survival in cirrhotic patients who received TIPS.

2D shear wave elastography of the rectus femoris muscle in patients with cirrhosis: Feasibility and clinical findings. A pilot study

BACKGROUND AND AIMS

Frailty is frequent in cirrhosis and associated with skeletal muscle abnormalities and worse prognosis. 2D shear-wave elastography (2D-SWE) could mirror biomechanical properties of skeletal muscle reflecting muscle quality. However, there is no data on 2D-SWE on skeletal muscle stiffness assessment in cirrhosis and on frailty.

METHODS

Outpatients with cirrhosis were prospectively included in a single center. Skeletal muscle stiffness was studied at the rectus femoris by 2D-SWE. Ileo-psoas area and index (area/height²), and antero-posterior diameter of rectus femoris (RF) was measured on ultrasound.

RESULTS

We included 44 patients (24 male, age 59 [IQR 49-66]) with a median liver frailty index (LFI) of 3.7 (IQR 3.2-4.0). Measurement of RF muscle stiffness (RFMS) was feasible in all with high inter-measurement reproducibility. RFMS did not correlate with LFI, liver function and skeletal muscle diameters. Ileo-psoas index was lower in frail patients (1.7 vs 1.0 cm²/m², p = 0.024). RF antero-posterior diameter inversely correlated with LFI (r -0.578: p<0.001).

CONCLUSION

RFMS by 2D-SWE is feasible and reproducible in cirrhosis and is independent of liver function and LFI, and warrants further studies in this setting. RF antero-posterior diameter could be reported as an objective parameter mirroring sarcopenia and frailty.

Hepatic manifestations of drug reaction with eosinophilia and systemic symptoms syndrome

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a potentially life-threatening drug reaction, which can affect multiple organs. Patients with DRESS syndrome and hepatic manifestations may present alterations ranging from mild hepatitis to acute liver failure. The diagnosis might be difficult, and the management of these patients is challenging. This report analyzes a series of five cases reporting the clinical presentation, which ranged from acute hepatitis to liver failure, and discussed their treatment.

Early profiles of clinical evolution after intravenous thrombolysis in an unselected stroke population

BACKGROUND

Intravenous recombinant tissular plasminogen activator (rt-PA) is the only approved pharmacological treatment for acute ischaemic stroke. The authors aimed to analyse potential causes of the variable effect on early course and late outcome.

METHODS AND RESULTS

136 patients (42% women, 58% men) treated with intravenous rt-PA within 3 h of stroke onset in an acute stroke unit over a 3-year period, were included. Early clinical profiles of evolution at 48 h were divided into clinical improvement (CI) (decrease >4 points in the National Institute of Health Stroke Scale (NIHSS)); clinical worsening (CW) (increase >4 points NIHSS); clinical worsening after initial improvement (CWFI) (variations of >4 points in the NIHSS). Patients with clinical stability (no NIHSS modification or <4 points) were excluded. The patients showed in 66.9% CI, 13.2% CW 8.1 % CWFI and 11.8% remained stable. Female sex, no hyperlipaemia and peripheral arterial disease were associated with CW. Male sex and smoking were associated with CI. Absence of arterial occlusion on admission (28.4%) and arterial recanalisation at 24 h were associated with CI. Main causes of clinical deterioration included symptomatic intracranial haemorrhage (sICH), persistent occlusion and cerebral oedema. 23.5% developed ICH, 6.6% of which had sICH. At 3 months, 15.5% had died. Mortality was increased in CW, mainly related to sICH and cerebral oedema. The outcome of CWFI was intermediate between CW and CI.

CONCLUSIONS

Early clinical profiles of evolution in thrombolysed patients vary considerably. Even with CI, it is critical to maintain vessel permeability to avoid subsequent CW.

Perfusion computed tomography-guided subacute endovascular reperfusion in a patient with carotid occlusion

Most patients with symptomatic internal carotid artery occlusion have a single minor or major hemispheric stroke. A minority of patients have ipsilateral retinal ischemia, recurrent strokes, or transient ischemic attacks. Whereas spontaneous carotid recanalization is rare, acute surgical recanalization has been attempted, with mixed results. Recently, acute endovascular recanalization has been performed and described as feasible and relatively safe. We describe a patient with symptom recurrence related to hemodynamic factors after occlusion of the carotid artery who was successfully treated 14 days after symptom onset.

Adaptation of pregnant ewes to an exclusive onion diet

A diet consisting entirely of cull onions fed to pregnant ewes produced Heinz body hemolytic anemia in all sheep after 21 d. After 28 d of daily consumption of 20 kg of onions/ewe, the anemia stabilized, and for the remaining 74 d the packed cell volume increased in the majority of sheep, although it did not return to normal. Compared to control ewes fed an alfalfa and grain diet, the onion-fed ewes had comparable body condition scores and fleece weights. There was no significant difference (alpha = 0.05) in pregnancy or lambing rate, number of lambs born/ewe exposed, or number of lambs born/ewe lambing. Greater numbers of sulfate-reducing bacteria (Desulfovibrio spp) and more ruminal hydrogen sulfide were present in onion-fed sheep compared to controls. Although an average 27% reduction in packed cell volume and Heinz body anemia developed in the onion-fed ewes, on the basis of this study it appears that pregnant ewes may be fed a pure onion diet with minimal detrimental effects. This adaptation to a pure onion diet is in part likely due to the apparent ability of the sheep's rumen to quickly develop a population of sulfate-reducing bacteria that decrease the toxicity of onion disulfides.

The Irish cystic fibrosis database

We have found records of 1014 Irish cystic fibrosis patients alive by December 1994, belonging to 883 families. Prevalence in the population is 1/3475 and incidence at birth 1/1461, with a gene frequency of 2.6%. Twenty percent of the patients are aged over 20 years, but at present survival rate falls rapidly after that age. We have identified 85% of the mutations on the CFTR gene in a sample of 29% of the families (506 CF chromosomes). Mutation delta F508 is found in 72% of Irish CF chromosomes, G551D in 6.9%, and R117H in 2%. These are the highest frequencies reported for the latter two mutations world wide. Another seven mutations are found in an additional 4% of CF families. We present new microsatellite haplotype data that could be useful for genetic counselling of CF families bearing some of the 15% of CF mutations still unidentified, and comment on possible uses of our database.
