Background Ultrasonography is limited for differentiating portal hypertension due to liver cirrhosis from that secondary to hepatosplenic schistosomiasis (HSS). We aimed to investigate the role of transient elastography (TE) in differentiating HSS mansoni from cirrhosis and the factors associated with liver and spleen stiffness (LS and SS) in HSS. Method A cross-sectional study was conducted including patients with HSS mansoni (n=29) and liver cirrhosis due to non-alcoholic steatohepatitis (n=23). All patients underwent TE and those with HSS were assessed by the Niamey protocol. Results HSS subjects presented lower median LS (9.6 vs 21.3 Kpa, p Conclusion TE can play a role in differentiating HSS from cirrhosis, especially by LS. SS may be further investigated for predicting complications in HSS.

Background Portal vein thrombosis (PVT) has been described in nearly 50% of patients who underwent oesophagogastric devascularization combined with splenectomy (EGDS), but no previous study has compared its occurrence in surgical and non-surgical groups. This study aimed to investigate PVT in hepatosplenic schistosomiasis (HSS) and its association with EGDS and upper variceal bleeding (UVB). Methods Retrospectively, 104 HSS individuals were enrolled. Following EGDS, the occurrence of PVT, mesenteric vein thrombosis (MVT), hospital admissions and UVB were recorded. Results EGDS was performed in 27 (26%) patients. PVT and MVT were detected in 30 (33%) and 8 (9.8%) patients, respectively. Patients who underwent EGDS were at greater risk of PVT (63% vs 19.7%; odds ratio [OR] 6.12 [95% confidence interval {CI} 2.3 to 16.1], p Conclusions EGDS was not associated with a decreased frequency of UVB when compared with the non-surgical approach but was an independent risk factor for PVT.

Background Sarcopenia is a common complication of cirrhosis and an important predictor of morbimortality. We aimed to determine the prevalence of sarcopenia and its associated factors in hepatosplenic schistosomiasis (HSS) as well as to evaluate whether muscle mass and function are associated with variceal upper gastrointestinal bleeding (VUGIB) and previous splenectomy in subjects without other liver diseases. Methods We conducted a cross-sectional study including adults with HSS who underwent clinical, biochemical, anthropometric, muscle strength and physical performance evaluations and were submitted to bioelectrical impedance analysis and abdominal ultrasound. Sarcopenia was diagnosed according to the 2019 European consensus criteria. Results A total of 66 patients with HSS (62.1% male; mean age 48.8±8.6 y) were included. Overall, six subjects (9.1%) were diagnosed with probable sarcopenia and none had confirmed sarcopenia. Fat-free body mass index (BMI) was independently associated with VUGIB (odds ratio 0.701 [95% confidence interval 0.51 to 0.96]; p=0.025). Compared with patients who did not undergo surgery, individuals who underwent esophagogastric devascularization combined with splenectomy (EGDS) had higher serum lipid levels, fat percentage and frequency of metabolic syndrome, with lower skeletal muscle mass index and hand grip strength. Conclusions HSS mansoni seems not to cause sarcopenia. However, a lower fat-free BMI was associated with previous VUGIB and the subgroup of patients who underwent EGDS presented higher lipid levels, fat percentage and frequency of metabolic syndrome and lower muscle mass and function.

Background No previous study have evaluated transient elastography (TE) for predicting esophageal varices (EV) in hepatosplenic schistosomiasis (HSS). Aim To investigate noninvasive methods of predicting EV in patients with HSS mansoni. Methods Cross-sectional multicentric study included 51 patients with HSS. Patients underwent ultrasonography-dopplerfluxometry, upper endoscopy, complete blood cell count and TE (Fibroscan®) for liver and spleen stiffness measurement (LSM and SSM). Noninvasive scores previously established for cirrhotic population were studied: platelet count to spleen diameter ratio (PSR), LSM-spleen diameter to platelet ratio score (LSPS) and varices risk score (VRS). We proposed a version of LSPS and VRS by replacing LSM with SSM and named them SSPS and modified-VRS, respectively. Results EV was detected in 42 (82.4%) subjects. Individuals with EV presented higher SSM (73.5 vs 36.3 Kpa, p=0.001), splenic vein diameter (10.8 vs 8.0 mm, p=0.017), SSPS (18.7 vs 6.7, p=0.003) and modified-VRS (4.0 vs 1.4, p=0.013), besides lower PSR (332 vs 542, p=0.038), than those without EV. SSPS was independently associated with EV presence (OR=1.19, 95%CI 1.03-1.37, p=0.020) after multivariate analysis. In a model excluding noninvasive scores, SSM was independently associated with EV diagnosis (OR=1.09, 95%CI 1.03-1.16, p=0.004). AUROC was 0.856 (95%CI 0.752-0.961, p=0.001) for SSM and 0.816 (95%CI 0.699-0.932, p=0.003) for SSPS (p=0.551). Conclusions Spleen-related variables were predictors of EV: SSM, splenic vein diameter, SSPS, modified-VRS and PSR. Multivariate models indicated that SSM and SSPS are useful tools for predicting EV in non-cirrhotic portal hypertension by HSS and may be used in clinical practice.
