Hydrocephalus is a prevalent health problem that is frequently encountered by paediatric neurosurgeons during infancy and childhood. We report a case of an 11-year-old boy with high cerebrospinal fluid protein hydrocephalus secondary to optic glioma that required a ventriculoperitoneal (VP) shunt. The patient had multiple failures of VP shunt and developed massive ascites. Alternatively, the hydrocephalus was treated by ventriculo-gallbladder (VG) shunt in the presence of sludge which was removed from the gallbladder before placement of the shunt. After VG shunt insertion, the patient expressed signs of infection with elevated liver profile, which emphasised the presence of gallstones. While the shunt was kept in its place without any complications, the gallstones were successfully removed by an endoscopic retrograde cholangiopancreatography. In conclusion, the presence of sludge is not a contraindication for VG shunt placement, and, if the VG shunt was complicated with gallstones, it could be treated without the need for cholecystectomy.
Individuals on immunosuppression were excluded from COVID-19 vaccine trials. We evaluated immune responses to COVID-19 vaccine BNT162b2 (Pfizer-BioNTech) in people taking methotrexate and biologics. Given the roll out of extended interval vaccination programmes to maximise population coverage, we present findings following the first dose. We recruited individuals with psoriasis (n¼84) established on methotrexate or biologic monotherapy (TNF, IL-17 or IL-23 inhibitors) and healthy controls (n¼17). Immunogenicity was evaluated pre and post (day 28) vaccine. Seroconversion rates were lower in patients taking immunosuppression (78%, 95%CI 67-87%) compared to controls (100%, 95%CI 79-100%), with the lowest rate in those on methotrexate (50%, 95%CI 26-74%). Neutralising activity to wild-type SARS-CoV-2 was lower in patients receiving methotrexate (median ID 50 152, IQR 47-257) compared to controls (median ID 50 316, IQR 212-481, p<0.01), but preserved in those receiving biologics (median ID 50 280, IQR 137-428). Neutralising titres against B.1.1.7 were comparably low in all participants. Spike-specific T cell responses (including IFNg, IL-2, IL-21) were induced in all groups, and were equivalent among individuals receiving methotrexate, biologics and controls. Functional humoral immunity to a single dose of BNT162b2 is impaired by methotrexate but not by biologics, while cellular responses are unaffected. Seroconversion alone may not adequately reflect vaccine immunogenicity in individuals with immune-mediated disease receiving immunosuppression. Real-world pharmacovigilance studies will determine whether these findings translate to clinical effectiveness.
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.
