NCs occur commonly after solid organ transplantation and affect 15%-30% of liver transplant recipients. The aim of this retrospective study was to evaluate the type and incidence of neurologic events in pediatric patients following LT. Between May 2006 and June 2015, 242 patients (118 females, 124 males) requiring LT for different etiologies at the İnönü University Liver Transplantation Institute were included. The incidence, types, and risk factors of NCs that occurred following LT were evaluated retrospectively. Neurologic events occurred in 57 (23.5%) of the patients. Early NCs were encephalopathy (12.4%), seizures (11.5%), and PRES (7%). Of 57 patients, five (8.7%) experienced NCs at least 1 month after LT; these late NCs included tremor, headaches, encephalopathy, ataxia, and neuropathy. The psychiatric symptoms after LT were noted in 42 patients (17.4%). The mortality rate after LT in those with or without neurological events was not significantly different (P=.73). There was a high incidence of serious neurologic events after LT. The major neurologic manifestation in our patients was encephalopathy followed by seizures.
Paraneoplastic cerebellar degeneration (PCD) can occur severely and appear as subacute cerebellar syndrome. PCD may be associated with small cell lung cancer, adenocarcinoma, breast cancer, ovarian carcinoma, and Hodgkin's lymphoma. An 11-year-old male was admitted with acute cerebellar ataxia, dysarthria, and diplopia. Mediastinal conglomerated lymph nodes were depicted in a chest computed tomography (CT) examination, and diagnosis of stage IV Hodgkin's lymphoma was obtained after a lymph node biopsy. The antibodies against Purkinje cells (anti-Tr antibody) were positive immunohistochemically. Thus, paraneoplastic cerebellar degeneration depending on Hodgkin's disease was diagnosed. Despite the completion of chemotherapy, neurological recovery was not observed in the patient and plasmapheresis with immunoadsorption, and intravenous immunoglobulin (IVIG) was performed. Truncal ataxia, gait disturbance, and tremors decreased. Consequently, we thought that plasmapheresis with the immunoadsorption method and IVIG therapy might be a treatment option for cerebellar ataxia caused by a mechanism of immune ancestry.
Background
The pathogenesis and clinical manifestations of the multisystem inflammatory syndrome in children (MIS-C) has not yet been fully elucidated and there is no clear consensus on its treatment yet.
Objectives
To evaluate our patients diagnosed with MIS-C and present them to the literature in order to contribute to the better understanding of this new disease, which entered paediatric practice with the SARS-CoV-2 peak.
Methods
In this study, 17 MIS-C cases diagnosed according to the Centers for Disease Control and Prevention criteria were included.
Results
Of the patients, 7 (41.2%) had a comorbidity. Gastrointestinal system involvement was the most prominent in the patients (70.6%). Laparotomy was performed in 3 patients due to acute abdomen. Two patients had neurological involvement. Of the patients, 15 (88.2%) received intravenous immunoglobulin and 13 (76.5%) received both intravenous immunoglobulin and methylprednisolone. Two patients received invasive mechanical ventilation and 4 patients received high flow rate nasal cannula oxygen therapy. One of our patients who needed invasive mechanical ventilation and high vasoactive-inotrope support died despite all supportive treatments including plasmapheresis and extracorporeal membrane oxygenation.
Conclusions
MIS-C picture can have a fatal course and may present with severe gastrointestinal and neurological signs. Unnecessary laparotomy should be avoided.
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.
