RESUMO
Tofacitinib is a Janus kinase inhibitor indicated to treat adult patients with moderately to severely active ulcerative colitis (UC). Although thrombosis is a known adverse event of tofacitinib, there are no reports specific to cerebral venous sinus thrombosis (CVST). We present a report of a patient presenting with a CVST several months after starting tofacitinib. Initially, this 60-year-old man with poorly controlled UC who previously had a nonthrombotic hemorrhage was found to have venous sinus thromboses of the right transverse and sigmoid sinuses. Hematological workup did not reveal any underlying hypercoagulable conditions, aside from UC. This is the first report of a patient with CVST likely resulting from the Janus kinase inhibitor tofacitinib. This case report should prompt compilation of all thrombotic events in patients receiving tofacitinib.
RESUMO
PURPOSE: A patient with carbapenem-resistant Klebsiella pneumoniae infection is described, and treatment options are discussed. SUMMARY: Few antibiotics to treat carbapenem-resistant Enterobacteriaceae (CRE) infection are available, and treatment is further complicated by the limited ability of many antibiotics to penetrate into the cerebrospinal fluid (CSF). Currently, there is a lack of clinical data on the treatment of central nervous system CRE infections, and therapy is based on case reports, case series, and small retrospective studies. A patient was admitted to the emergency department with intracranial hemorrhage and ventriculitis due to traumatic injury. A ventriculostomy and, subsequently, a ventriculoperitoneal (VP) shunt were placed. After approximately a month of treatment with various antibiotic regimens, the patient's VP shunt was externalized, and a CSF culture speciated carbapenem-resistant K. pneumoniae and Pseudomonas aeruginosa. The patient was then switched to i.v. ceftazidime-avibactam and intrathecal amikacin therapy. His CSF cultures were sterile 3 days after initiation of those antibiotics, and subsequent CSF cultures resulted in no growth. After the patient was treated with intrathecal amikacin 30 mg daily for 4 weeks and i.v. ceftazidime-avibactam 2.5 g every 8 hours for 6 weeks, the ventriculitis resolved, the external ventricular drain was removed, and he was transferred to a long-term care facility for rehabilitation. CONCLUSION: A man with ventriculitis caused by P. aeruginosa and carbapenem-resistant K. pneumoniae was successfully treated with i.v. ceftazidime-avibactam and intrathecal amikacin.
