The clinical manifestations of schistosomiasis pass by acute, sub acute and chronic stages that mirror the immune response to infection. The later includes in succession innate, TH1 and TH2 adaptive stages, with an ultimate establishment of concomitant immunity. Some patients may also develop late complications, or suffer the sequelae of co-infection with other parasites, bacteria or viruses. Acute manifestations are species-independent; occur during the early stages of invasion and migration, where infection-naivety and the host’s racial and genetic setting play a major role. Sub acute manifestations occur after maturity of the parasite and settlement in target organs. They are related to the formation of granulomata around eggs or dead worms, primarily in the lower urinary tract with Schistosoma haematobium, and the colon and rectum with Schistosoma mansoni, Schistosoma japonicum, Schistosoma intercalatum and Schistosoma mekongi infection. Secondary manifestations during this stage may occur in the kidneys, liver, lungs or other ectopic sites. Chronic morbidity is attributed to the healing of granulomata by fibrosis and calcification at the sites of oval entrapment, deposition of schistosomal antigen-antibody complexes in the renal glomeruli or the development of secondary amyloidosis. Malignancy may complicate the chronic lesions in the urinary bladder or colon. Co-infection with salmonella or hepatitis viruses B or C may confound the clinical picture of schistosomiasis, while the latter may have a negative impact on the course of other co-infections as malaria, leishmaniasis and HIV. Prevention of schistosomiasis is basically geared around education and periodic mass treatment, an effective vaccine being still experimental. Praziquantel is the drug of choice in the treatment of active infection by any species, with a cure rate of 80%. Other antischistosomal drugs include metrifonate for S. haematobium, oxamniquine for S. mansoni and Artemether and, possibly, Mirazid for both. Surgical treatment may be needed for fibrotic lesions.
We aimed to assess the pregnancy outcome in women with chronic HCV who had negative pregnancy test prior to the anti‐HCV course and had unintended pregnancy while on HCV treatment. Hundred patients with a mean age of 30 ± 6.7 y were included and advised to withhold antivirals and continue follow‐up in viral hepatitis and obstetrics centres till delivery. All patients received a 12‐weeks regimen of anti‐HCV [sofosbuvir plus daclatasvir (SOF/DCV): n = 95, SOF/DCV plus ribavirin: n = 3, and paritaprevir/ritonavir/ombitasvir plus ribavirin: n = 2]. Only nine patients completed the full antiviral course against medical advice, and 91 stopped between on‐treatment weeks 4 and 8. Eighty‐eight patients delivered full‐term babies, eight had preterm babies and two had abortions. Of the nine patients who completed the full course of DAAs, seven (77.8%) delivered normal babies, attended their post‐treatment week 12 visit, and all (100%) achieved sustained virological response. No major antiviral‐related adverse events were reported.
Hepatocellular carcinoma (HCC) represents one of the most challenging potentially curable tumors with high incidence, prevalence and mortality rates. For proper assessment, prognosis estimation and treatment decisions, at least seven important guidelines and staging systems were designated. Proper treatment needs the interaction of multidisciplinary HCC clinic to choose the most appropriate line of treatment. The different modalities of management include resection (surgery or transplantation), local ablation, chemoembolization, radioembolization and molecular targeted therapies with a wide range of investigational drugs that developed after the FDA approved sorafenib. Downstaging and bridging are two important strategies to manage HCC patients who will undergo liver transplantation to improve their postoperative survival. Finally, survival and prognosis depends on several prognostic factors that are either patient related or tumor related. In our study, we aim to provide an updated comprehensive review of the different aspects of liver cancer management starting from staging systems to the different applied treatment modalities.
Background Conflicting studies were proposed either suggested or denied the relationship between early hepatocellular carcinoma (HCC) recurrence and the use of direct-acting antivirals (DAAs) for chronic hepatitis C management Aim of the study To evaluate HCC recurrence rate post-DAAs and potential predictive factors. Study This prospective cohort study included all HCC patients achieved complete response attending our multidisciplinary HCC clinic, Cairo University, from November 2013 to February 2018. Group I (60 patients) who received DAAs after HCC ablation and group II (273 patients) who were DAAs-untreated. We studied factors that could play a role in HCC recurrence.Results The sustained virological response rate was 88.3% among DAA-treated patients. HCC recurrence rate was 45% in the post-DAA group vs. 19% in the non-DAAs group; P < 0.001. Mean survival was significantly higher in the post-DAA group (34.23 ± 16.16 vs. 23.92 ± 13.99 months respectively; P value <0.001). There was a significant correlation between HCC recurrence rate and age, male gender, mean size of tumors and time interval between complete HCC ablation and occurrence of HCC recurrence. Conclusion Our study reports high rate of HCC recurrence post-DAA therapy in patients treated with transarterial chemoembolization but not in those treated with curative measures. DAA therapy after curative treatment for HCC led to significantly earlier HCC recurrence, which correlated with specific clinic-pathologic features in our prospective singleinstitution study. However, future independent prospective randomized studies are warranted to evaluate this correlation which may lead to a change in the current standard-of-care approach to patients with hepatitis C virus-related HCC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
