Safety profile of the adjuvanted recombinant zoster vaccine: Pooled analysis of two large randomised phase 3 trials

Background

The ZOE-50 (NCT01165177) and ZOE-70 (NCT01165229) phase 3 clinical trials showed that the adjuvanted recombinant zoster vaccine (RZV) was ≥90% efficacious in preventing herpes zoster in adults. Here we present a comprehensive overview of the safety data from these studies.

Schizophrenia following new-onset refractory status epilepticus secondary to antiphospholipid syndrome

New-onset refractory status epilepticus (NORSE) is a drug-resistant status epilepticus that often has a catastrophic outcome. Our patient was diagnosed with NORSE and had an EEG reading that showed status epilepticus persisting for 8 months in general anesthesia. After autoimmune workup showed positive antiphospholipid antibodies, his seizure was controlled, and he was discharged with good condition apart from moderate cognitive impairment. However, he later developed schizophrenia. Although psychiatric disorders have been associated with antiphospholipid syndrome, to the best of our knowledge, it has not been reported to be associated with status epilepticus. We recommend vigilance of psychological complications of refractory status epilepticus’ patients for early psychiatric referral, diagnosis, and treatment.

New-onset refractory status epilepticus (NORSE) is a syndrome of new-onset drug-resistant status epilepticus that often has a catastrophic outcome. Epilepsy is usually associated with psychiatric disorders of different manifestations of which psychosis is an example.1 However, not much is found in the literature review regarding psychiatric disorders following NORSE although a recent study concluded 32% of NORSE patients ended up with altered behavioral states like aggression.2 Schizophrenia following NORSE like in the rare presentation of this case has not been reported in the literature review before, although an association between schizophrenia and autoimmune disorders like APS has been reported.3     

A drug safety evaluation of mogamulizumab for the treatment of cutaneous T-Cell lymphoma

Introduction: Cutaneous T-cell lymphomas (CTCL) are rare non-Hodgkin lymphomas of skin-homing T-cells that initially or mainly manifest cutaneously. Treatment of CTCL is challenging given the disease states’ varying presentation and prognosis. Systemic treatment options often lack comparative evidence and have relatively low response rates and short duration of response. The recent Food and Drug Administration (FDA) approval of mogamulizumab in adult patients with relapsed or refractory (R/R) CTCL after at least one prior line of therapy provided a new treatment option to patients with advanced disease.

Areas covered: The authors discuss basic information about CTCL and mogamulizumab’s mechanism of action. Then, the authors discuss the agent’s efficacy. Finally, the authors evaluate the safety of mogamulizumab in comparison to other agents available in CTCL.

Expert opinion: Mogamulizumab has been shown to be an effective and well tolerated therapy for patients with relapsed and refractory MF/SS with excellent activity in the circulating component of the disease.     

Functional beta-cells derived from umbilical cord blood mesenchymal stem cells for curing rats with streptozotocin-induced diabetes mellitus

INTRODUCTIONThis study aimed to investigate the therapeutic response to injected human umbilical cord blood mesenchymal stem cells (UCBMSCs) among albino rats with streptozotocin (STZ)-induced diabetes mellitus.METHODSControl group (GI; n = 25) rats were fed with standard rat diet. Rats with STZ-induced diabetes mellitus without (GII; n = 25) and with (GIII; n = 25) differentiated human UCBMSCs implantation were the test groups. Rats were sacrificed in Week 11 following implantation. Liver biopsies were sectioned and stained in order to highlight both the presence and function of impregnated cells in the liver tissue.RESULTSHaematoxylin and eosin-stained sections in GI and GII rats showed normal liver architecture while GIII rats showed presence of cell clusters inside the liver tissue and around the central veins. Cell clusters with blue cytoplasm were present in sections in GIII rats but absent in GI and GII rats, indicating the presence of injected differentiated human UCBMSCs. The anti-human insulin immunostaining of GIII rats showed clusters of cells within the liver parenchyma and around central veins, indicating that these cells were active and secreting insulin.CONCLUSIONUCBMSCs are proficient in differentiating into insulin-producing cells in vivo under specific conditions and, when transplanted into the liver of albino rats with STZ-induced diabetes mellitus, were able to secrete insulin and partially control the status of diabetes mellitus in rats.     

Conjunctival flap advancement with or without scleral graft for hypotony maculopathy after trabeculectomy

AIM: To introduce a novel technique for transscleral fixation of the PC-IOL that requires no sutures on the IOL haptics. METHODS: Instead of suturing polypropylene onto the IOL haptics, the method simply winds the thread on the haptics. Fifteen eyes of 15 patients underwent this technique and were followed up for more than 18 months. Surgical outcomes and post-operative complications were evaluated and compared with those of the conventional transscleral fixation method. RESULTS: Postoperative cylinder was significantly lower in the thread winding group than in the conventional transscleral fixation method group (-1.02±0.46 diopters vs -1.57±0.77 diopters; P=0.01). Further, no postoperative complications, such as optic capture, IOL dislocation, and hyphema, were detected in the thread winding group. CONCLUSION: We believe that our thread winding technique is better than previously reported methods because it is simple, mechanically stable, and free from suture-related complications.
