Clostridium difficile (C diff) colitis infection is the most common cause of nosocomial infectious diarrhea and the prevalence is increasing worldwide. Toxic megacolon is a severe complication of C diff colitis associated with high mortality. Gastrointestinal (GI) comorbidity and impaired smooth muscle contraction are risk factors for the development of C diff-associated toxic megacolon. We present a case of fulminant C diff colitis with toxic megacolon in a patient with Duchenne muscular dystrophy (DMD) in the intensive care unit. C diff colitis was diagnosed by clinical presentation and positive C diff DNA amplification test (polymerase chain reaction). The impairment of GI tract due to DMD predisposes these patients to severe C diff infection and toxic megacolon, as observed in this case report. For the same reason, the recovery of GI function in these patients can be prolonged. While surgery was conducted for relieving the pressure from toxic megacolon, fecal microbiota transplantation through colonoscopy resulted in successful resolution of the C diff symptoms, although the recovery is prolonged due to DMD.
Background:
Levetiracetam, a novel antiepileptic drug, has shown antidyskinetic effects in
experimental animal models of Parkinson's disease (PD). The tolerability and efficacy of levetiracetam
in reducing the levodopa-induced dyskinesia (LID) in PD patients have not been established. Therefore,
this study aims to synthesize evidence from published prospective clinical trials about the efficacy
of levetiracetam for the management of LID in PD patients.
Methods:
We followed the PRISMA statement guidelines during the preparation of this systematic review.
A computer literature search of PubMed, EBSCO, Scopus, MEDLINE, and the web of science
was carried out. We selected prospective clinical trials assessing the anti-dyskinetic efficacy of
levetiracetam for treating LID in patients with PD. The Abnormal Involuntary Movement Scale
(AIMS), Clinical Global Impression Score (GCI), UPDRS III, and UPDRS IV were considered as the
primary outcome measures; their data were extracted and reviewed.
Results:
Our review included seven clinical trials with a total of 150 patients. Of them, three studies
were randomized controlled trials, and the remaining were open-label single arm trials. Four studies
reported poor tolerability of the levetiracetam with mild anti-dyskinetic effects. Levetiracetam slightly
improved the UPDRS-IV and AIMS scores with small effect size. In the remaining three studies,
levetiracetam failed to exhibit any anti-dyskinetic effects.
Conclusion:
Current evidence does not support the efficacy of the levetiracetam for treating LID in
PD patients, however, due to the limited number of published randomized control trials (RCTs), further
RCTs are required.
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.
