Project description:RationaleAmong atrial fibrillation patients with high risk of bleeding, left atrial appendage occlusion has emerged as an alternative to long-term oral anticoagulation therapy for stroke prevention. Device-related thrombus remains a major concern because it may result in recurrent embolic events. To date, there is no consensus on the optimal method of treating device-related-thrombus.Patient concernsA 78-year-old man with atrial fibrillation had an episode of intracranial hemorrhage while taking warfarin. He subsequently underwent percutaneous placement of a 30-mm Watchman device to the left atrial appendage. He was prescribed dual anti-platelet therapy with aspirin and clopidogrel.DiagnosisReassessment echocardiography 3 months later found device-related thrombus.InterventionsThe antithrombotic regimen was switched from dual antiplatelet therapy to apixaban.OutcomesReassessment echocardiography 3 months later revealed complete resolution of the device-related thrombus. Apixaban was stopped. He had dual antiplatelet therapy for 6 more months followed by life-long aspirin. There was no bleeding complication since implantation of Watchman device.LessonsWe demonstrated successful treatment of device-related thrombus with a short course of apixaban with complete resolution of thrombus. Further randomized controlled trials are required to determine the choice and duration of drug therapy for device-related thrombus.

Project description:BackgroundThe prognosis of patients with recurrent World Health Organization (WHO) grade IV malignant glioma is dismal, and there is currently no effective therapy. We conducted a dose-finding and toxicity study in this population of patients, evaluating convection-enhanced, intratumoral delivery of the recombinant nonpathogenic polio-rhinovirus chimera (PVSRIPO). PVSRIPO recognizes the poliovirus receptor CD155, which is widely expressed in neoplastic cells of solid tumors and in major components of the tumor microenvironment.MethodsWe enrolled consecutive adult patients who had recurrent supratentorial WHO grade IV malignant glioma, confirmed on histopathological testing, with measurable disease (contrast-enhancing tumor of ≥1 cm and ≤5.5 cm in the greatest dimension). The study evaluated seven doses, ranging between 107 and 1010 50% tissue-culture infectious doses (TCID50), first in a dose-escalation phase and then in a dose-expansion phase.ResultsFrom May 2012 through May 2017, a total of 61 patients were enrolled and received a dose of PVSRIPO. Dose level -1 (5.0×107 TCID50) was identified as the phase 2 dose. One dose-limiting toxic effect was observed; a patient in whom dose level 5 (1010 TCID50) was administered had a grade 4 intracranial hemorrhage immediately after the catheter was removed. To mitigate locoregional inflammation of the infused tumor with prolonged glucocorticoid use, dose level 5 was deescalated to reach the phase 2 dose. In the dose-expansion phase, 19% of the patients had a PVSRIPO-related adverse event of grade 3 or higher. Overall survival among the patients who received PVSRIPO reached a plateau of 21% (95% confidence interval, 11 to 33) at 24 months that was sustained at 36 months.ConclusionsIntratumoral infusion of PVSRIPO in patients with recurrent WHO grade IV malignant glioma confirmed the absence of neurovirulent potential. The survival rate among patients who received PVSRIPO immunotherapy was higher at 24 and 36 months than the rate among historical controls.

Project description:Autologous chimeric antigen receptor (CAR) T cells targeted to epidermal growth factor receptor variant III (CAR T-EGFRvIII) have been developed and administered experimentally to treat patients with IDH1 wildtype recurrent glioblastoma (rGBM) (NCT02209376). We report the case of a 59-year-old patient who received a single peripheral infusion of CAR T-EGFRvIII cells and survived 36 months after disease recurrence, exceeding expected survival for recurrent glioblastoma. Post-infusion histopathologic analysis of tissue obtained during a second stage surgical resection revealed immunosuppressive adaptive changes in the tumor tissue as well as reduced EGFRvIII expression. Serial brain imaging demonstrated a significant reduction in relative cerebral blood volume (rCBV), a measure strongly associated with tumor proliferative activity, at early time points following CAR T treatment. Notably, CAR T-EGFRvIII cells persisted in her peripheral circulation during 29 months of follow-up, the longest period of CAR T persistence reported in GBM trials to date. These findings in a long-term survivor show that peripherally administered CAR T-EGFRvIII cells can persist for years in the circulation and suggest that this cell therapy approach could be optimized to achieve broader efficacy in recurrent GBM patients.

Project description:BackgroundPercutaneous patent foramen ovale (PFO) closure has been well established in the secondary prevention of cryptogenic stroke with overall low rates of procedural complications. One such complication is PFO closure device thrombus formation which is now rarely reported with newer generation devices.Case summaryWe present the unusual case of a 59-year-old woman with myelofibrosis who developed late-onset recurrent embolic strokes related to Amplatzer PFO closure device thrombus whilst therapeutically anticoagulated on Warfarin. Surgical management was deemed too high risk and our patient was conservatively managed with enoxaparin. Serial transthoracic echocardiography demonstrated a reduction in thrombus size and the patient had no further neurological events.DiscussionOverall, the risk of serious complications following percutaneous PFO closure, such as device-associated thrombus, remains low. The risk of thrombus formation in patients with hypercoagulable states is not well characterized. Despite good evidence for the efficacy in preventing recurrent cryptogenic stroke, the role of PFO closure in addition to anticoagulation is unclear. Given this uncertain benefit of PFO closure in anticoagulated patients and the unclear risk profile, patient selection, and thorough pre-procedural evaluation are vital when assessing the appropriateness of percutaneous PFO closure.

Project description:BackgroundAllergic contact stomatitis (ACS) is common among people with allergic constitution and who have allergy reaction to specific allergen such as drugs, food, and materials because of immune dysfunction. With the development of materials science, the increasing diversity of cosmetics and food additives has gradually raised the incidence rate of ACS. Now systemic and local therapy are adopted in the therapy of ACS. However, the systemic therapy would drop the drugs' concentration after it reaches the treatment area through the layers of human barriers, while the locally-used drugs such as collutory may not be suitable for patients with skin lesion. Kangfuxin contains a variety of biological extracts which is anti-inflammatory and curative and can produce connective tissues whether it's skin or mucous membrane. It can be used not only in non-oral diseases such as gastric ulcer or gynecological diseases, but also in the treatment of recurrent aphthous ulcer and many kinds of stomatitis and has shown good anti-inflammatory and curative effects. This study aimed to explore the effectiveness of Kangfuxin solution as a local-used adjuvant drug to treat ACS.Case descriptionWe present a 22-year-old male with ACS whose complaint at the first visit was severe pain, accompanied by salivation, tongue enlargement, bleeding, tonsil enlargement, and symptoms of difficulty in eating, fatigue, and dizziness. After the physical and laboratory examination, we found no abnormalities other than a history of eating the kiwi fruit, which is a common allergen. Thus, he was diagnosed as ACS. In this case, we provided a pharmacologic therapeutic intervention of chlorpheniramine (one tablet, three times a day) and Kangfuxin solution (gargle for 15 min, three times a day) with advice that no exposure to the allergen. On the third day, the patient felt no significant relief of symptoms, while one week after the first visit, the symptoms had obviously alleviated and most of the red lip erosion disappeared. The patient recovered completely with no discomfort in ten days after the initial visit.ConclusionsThis study investigated the therapeutic effect of Kangfuxin solution combined with chlorpheniramine on ACS.

Project description:IntroductionCurrently, no consensus on optimal renal replacement modality has been reached for end-stage renal disease (ESRD) patients complicated with hemophilia. They may require infusion of coagulation factors during each hemodialysis session. In comparison, peritoneal dialysis (PD) might be preferred considering that coagulation replacement is only required for catheter placement. However, limited data on the safety and efficacy of PD for treating ESRD patients with hemophilia were reported.MethodsThis is a single-center retrospective cohort study. ESRD patients diagnosed with hemophilia under PD in Peking Union Medical College Hospital from January 1, 1996 to December 31, 2021 were included and followed-up with every month. Their baseline clinical data, catheter insertion procedure, coagulation factor replacement, complications, and outcome were analyzed and compared with general PD patients.ResultsIn total, 8 patients diagnosed with hemophilia were included, all-male, with a mean age of 50.3±13.3 years old. Two were acquired hemophilia A, whereas the rest were hereditary hemophilia A (HHA). Seven patients experienced significant hemoglobin (Hgb) increment after PD. Peritoneal hemorrhage only consisted of a small portion of all hemorrhage. Patients with hemophilia seemed to have lower small solute clearance despite higher baseline peritoneal permeability, and appeared to have increased peritonitis rate than other male PD patients, yet this study is not powered to prove this.ConclusionPD is a safe and effective choice for patients with hemophilia and ESRD requiring dialysis. More studies are required to evaluate this certain rare group of patients.

Project description:Kartagener syndrome (KS) is an autosomal recessive disorder characterized by situs inversus, paranasal sinusitis and bronchiectasis. We report the successful use of double lung transplant (DLTx) to treat end-stage KS. A 49-year-old Han woman was admitted to Renmin Hospital (Wuhan University, China) in September 2017 with a ?15 year history of chronic productive cough that had worsened during the past year. Clinical examination and imaging investigations revealed respiratory failure and situs inversus consistent with KS. The patient was successfully treated with DLTx involving bilateral bronchial anastomoses. DLTx is a feasible treatment option for end-stage KS.

Project description:Mainzer-Saldino syndrome (MSS) or conorenal syndrome (CRS) is a rare autosomal recessive ciliopathy characterized by multiorgan affection, typically presents with a triad of nephronophthisis (NPHP), retinitis pigmentosa (RP), and cone-shaped epiphysis (CSE) with varying degrees of severity. A 20-month-old male is experiencing recurrent pneumonia attacks, an elevated serum creatinine level, proteinuria, and high anion gap partially compensated metabolic acidosis were incidentally discovered during one of his hospitalizations. A biopsy was performed, and the results supported the diagnosis of Alport syndrome. However, a subsequent genetic test suggests the presence of MSS. Aside from NPHP, RP and CSE tested positive. Based on the fact that MSS is not a common cause of end-stage renal disease (ESRD) in pediatrics, physicians should bear in mind genetic testing as a decisive tool. In this context, we highlighted a case of an accidentally discovered impaired renal function from first presentation to final diagnosis, with a valuable comparison with previously published similar cases.

Project description:There are few effective treatments for recurrent glioblastoma multiforme (GBM). We present a patient with recurrent GBM who achieved a prolonged response to treatment with afatinib, an irreversible ErbB family blocker, plus temozolomide. A 58-year-old female patient was diagnosed with multifocal primary GBM. After surgical resection, first-line therapy comprised radiotherapy and temozolomide. Following disease progression after 3 temozolomide cycles, the patient entered a phase I/II clinical trial of afatinib (20-40 mg daily for 28 days) plus temozolomide (50 mg/m2 every 21/28 days). Next-generation sequencing analysis of the brain tumor specimen was performed. At the last assessment, 63 treatment cycles had been completed and the patient had survived for ~5 years since recurrence. Significant disease regression was observed after 5 cycles and was maintained during long-term follow-up. Adverse events were consistent with the known tolerability profile of afatinib and were managed by treatment interruption/dose reduction. The patient had several epidermal growth factor receptor (EGFR) aberrations, including gene amplification and EGFRvIII positivity. Three somatic mutations were identified, including an unprecedented extracellular-domain substitution (D247Y). The patient has survived ~6-fold longer than normally expected in patients with recurrent GBM. The complex EGFR genotype may underlie sustained response to afatinib plus temozolomide.

Project description:BackgroundGlioblastoma is a malignant tumor, and its prognosis is as poor as 1.5 to 2 years. Most cases recur within one year even under the standard treatment. The majority of recurrences are local, and in rare cases, metastasize mostly within the centra nervous system. Extradural metastasis of glioma is exceedingly rare. Here, we present a case of vertebral metastasis of glioblastoma.Case presentationWe present a 21-year-old man post total resection of the right parietal glioblastoma, diagnosed with lumbar metastasis. He originally presented with impaired consciousness and left hemiplegia and underwent gross total resection of the tumor. Given the diagnosis of glioblastoma, he was treated with radiotherapy combined with concurrent and adjuvant temozolomide. Six months after tumor resection, the patient presented with severe back pain, and was diagnosed as metastatic glioblastoma on the first lumbar vertebrae. Posterior decompression with fixation and postoperative radiotherapy were conducted. He went on to receive temozolomide and bevacizumab. However, at 3 months after the diagnosis of lumbar metastasis, further disease progression was noted, and his care was transitioned to best supportive care. Comparison on copy number status between primary and metastatic lesions on methylation array analysis revealed more enhanced chromosomal instability including 7p loss, 7q gain and 8 gain in the metastatic lesion.ConclusionBased upon the literature review and our case, younger age of initial presentation, multiple surgical interventions, and long overall survival seem to be the risk factors of vertebral metastasis. As the prognosis of glioblastoma improves over time, its vertebral metastasis is seemingly more common. Therefore, extradural metastasis should be kept in mind in the treatment of glioblastoma. Further, detailed genomic analysis on multiple paired specimens is mandated to elucidate the molecular mechanisms of vertebral metastasis.
