The target of this research was to investigate the effect of Balanities aegyptiaca fruit aqueous extract (200 mg/kg BW), alone or in combination with Praziquantel PZQ (300 mg/kg BW) on some biochemical, parasitological, liver histopathology and immunohistochemical parameters in mice infected with Schistosoma mansoni. Results showed that treatment of S. mansoni-infected mice with B. aegyptiaca alone or in combination with PZQ significantly reduced the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) as compared to that of the S. mansoni-infected mice group. Treatment of S. mansoni-infected mice with B. aegyptiaca or PZQ and their combination led to a significant reduction in the activity of malondialdehyde (MDA) as compared with the infected control group. While a significant elevation was observed in the activities of antioxidant enzymes glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and nitric oxide (NO) compared with the infected. Results revealed that the diameter and number of egg granuloma were significantly condensed after treatment of S. mansoni-infected mice with B. aegyptiaca, PZQ or their combination in hepatic and intestinal tissue. The histopathological alterations observed in the liver of S. mansoni-infected mice were remarkably recovered after B. aegyptiaca treatments. The reduction in angiogenesis was mostly observed in the group receiving the combination of B. aegyptiaca and PZQ. The alterations in vascular endothelial growth factor (VEGF) expression were significantly less in the liver sinusoids. Overall, B. aegyptiaca significantly inhibited the liver and intestinal damage accompanied by schistosomiasis. It demonstrated potent antioxidant and immunoprotective activities. This study advises that B. aegyptiaca can be considered promising for the development of a complementary and/or alternative against schistosomiasis.

In the present study, the hexane extract from branches of (Winteraceae) displayed potent activity against parasites (100% mortality of the worms at 200 μg/mL). Bioactivity-guided fractionation afforded, in addition to the previously reported bioactive sesquiterpene 3,6-epidioxy-bisabola-1,10-diene, two chemically related drimane sesquiterpenes-polygodial () and 9-deoxymuzigadial (). The anti- effects for compounds and were determined in vitro, with compound demonstrating significant potency (EC value of 10 μM for both male and female worms), while was inactive.

Hepato-intestinal schistosomiasis is characterized by severe pathological changes at advanced chronic stages, including granulomatous lesions and liver fibrosis. The objective of our research was to assess the dynamic expression of profibrotic molecules, the transforming growth factor beta 1 (TGF-β1), and proinflammatory cytokines immunomodulation induced by interleukin 17 (IL-17) neutralization in murine Schistosomiasis mansoni. The study included 56 specific pathogen-free male C57BL/6 mice, divided into 3 main groups: GI uninfected normal controls, GII S.

Chronic inflammation, oxidative stress, and DNA damage are observed in schistosomiasis and premature aging. However, the potential of these events to trigger stress-induced premature senescence (SIPS) throughout schistosomiasis progression remains overlooked, especially in response to the first-line pharmacological treatment. Thus, we investigated the relationship between oxidative stress and SIPS sentinel markers in untreated Schistosoma mansoni-infected mice and those receiving praziquantel (Pz)-based reference treatment.

This study investigates whether Cerastes cerastes venom (CCV) administrated at different doses (3 and 6μg/mouse) and times (a week pre-infection, the first week post-infection, and the fifth week post-infection) possesses antischistosomal activity on Schistosoma mansoni infected mice. The results showed that treatment with half lethal dose (6 μg/mouse) of CCV, at various time schedules, led to a significant decrease in the total worm burden. However, quarter lethal dose (3μg/mouse) of CCV showed a significant decrease in the total worm burden only when administered a week pre-infection.

Despite the long history of experimental trials to combat schistosomiasis, it remains a significant burden due to drug resistance and the effectiveness of the standard treatment only against the mature stage, while skipping other early developmental stages thus leading to severe permanent pathological sequelae. Therefore, repurposing a commonly used well-known safe drug would be a wise alternative. We investigated the potential anti-schistosomal drug activity of Daflon® (DAF) against different schistosomal developmental stages.
