2565 Background: PD-1/L1 inhibitor therapy has become the standard of care for many advanced solid tumors. A notable limitation of PD-1/L1 inhibitor therapy is the concern for AESI that are likely to be immune related. It is unclear whether a history of autoimmune events is a predisposing risk making these adverse events more likely. We aimed to evaluate the association between autoimmune-associated PMH and AESI on PD-1/L1 inhibitors. Methods: We pooled data across seven pivotal trials for PD-1/L1 inhibitors in urothelial cancer (UC) identifying patients with AESI submitted from 2016 - 2017. AESI were determined using a pooled preferred term list for each trial. Information collected from trials included PMH, AESI events and toxicity grade. Results: In total, 1747 immunotherapy treated patients were identified, with 1068 (61%) having an AESI and 277 (26%) having an autoimmune-related PMH. The most common autoimmune-associated events in the PMH were thyroid disorders (64%), asthma (23%), atopic dermatitis/eczema (6%), irritable bowel syndrome (5%), and psoriasis (4%). AESI occurred in 68% of patients with an autoimmune-related PMH and 60% of patients without an autoimmune-related PMH. The most common AESI in patients with an autoimmune-related PMH were diarrhea (35%), rash (27%), renal disorder (27%), and pruritis (23%). The most common AESI in the general trial population were diarrhea (28%), pruritis (26%), rash (25%), increased creatinine (14%), and elevated AST and ALT (10% and 9%). The majority of events were Grade 1-2 (87% in patients with an autoimmune-related PMH and 84% in the general trial population). Conclusions: Pooled clinical trial data shows a slight numeric increase in AESIs in patients with autoimmune-associated PMH. Limitations include potential lack of consistency of PMH documentation and adverse event reporting. There did not appear to be a pattern of association between PMH and type of AESI event. Grades of AESI events in the population with autoimmune-associated PMH were similar to the general trial population. This suggests that PD-1/L1 inhibitors may be safely administered to patients with UC and a PMH of some autoimmune-associated events. Further exploration is needed.

Checkpoint Inhibitor Therapy

Immune checkpoint inhibitor therapy (ICIT) is now standard of care for a variety of cancers in both the metastatic and adjuvant settings. As a result, it is imperative to understand the timing, epidemiology, monitoring, diagnosis, and management of immune related adverse events (irAEs) associated with ICIT. This article reviews specific irAEs by organ system, consolidating recommendations from multiple guidelines and incorporating data from case reports to highlight additional evolving therapeutic options for patients. Managing these adverse events requires early recognition, early intervention, and education of both patients and the multidisciplinary health care team. Given the durable responses observed with ICIT, and the irreversible nature associated with some of these irAEs, further research into management of the sequelae of ICIT is required.

Objective: Angiotensin-converting enzyme (ACE) inhibitor therapy is considered the standard of care for the treatment of congestive heart failure. Despite this, clinical experience suggests that not all patients may be receiving ACE inhibitor therapy or may be receiving low dosages. This study was performed to better understand the use of ACE inhibitor therapy in clinical practice. Design and Participants: We reviewed the medical therapy of 110 patients with a history of congestive heart failure referred to an outpatient heart failure clinic at a university teaching hospital. Outcome Measures: This observational study evaluated the use of ACE inhibitors, including dosage, as well as other drugs to treat congestive heart failure. Results: Approximately 85% (93/110) of patients were receiving an ACE inhibitor. Twenty percent (22/110) were receiving enalapril 20 mg/d or more, captopril 150 mg/d or more, lisinopril 20 mg/d or more, or quinapril 40 mg/d or more. The remaining patients (n = 71) were receiving these drugs at lower dosages. However, 21 of the remaining patients (19% of all patients) were receiving lower dosages based on patient-specific parameters; 47 of the remaining patients (43% of all patients) were eligible to have their dosage increased. Ten eligible patients were not receiving an ACE inhibitor. The majority of patients were also receiving digoxin (70%) and loop diuretic (80%) therapy. Conclusions: Approximately 85% of patients were receiving ACE inhibitor therapy, with 9% of eligible patients not receiving an ACE inhibitor. In the patients receiving ACE inhibitor therapy, approximately 50% (47/93) were receiving dosages below those suggested in the guidelines. Overall, the use of ACE inhibitor therapy is varied and intervention appears required to ensure that all patients receive appropriate therapy for the treatment of congestive heart failure.

After a short overview of the history of probiotics, the author presents the development of human intestinal microflora based on the newest genetic data and the microbiological features of main probiotics. The indications of probiotic administration have been defined and extended in recent years. The author reviews significant results of probiotic treatment in some gastrointestinal diseases based on meta-analytical data. Probiotics are useful in preventing and treating diarrhoea caused by antibiotics and Clostridium difficile caused diarrhoea. In the treatment of Helicobacter pylori infection, preparations containing certain Lactobacillus,Bifidobacterium strains or Saccaromyces boulardii could enhance by 5–10% the rate of successful eradication and reduce the incidence and severity of the side effects. Some symptoms of irritable bowel syndrome and thus the quality of life can be improved by probiotics. Their beneficial effect in ulcerative colitis was proven, while in Crohn’s disease has not yet been defined. The use of probiotics is not included in guidelines, with the exception of the Maastricht IV/Florence consensus. For each disease it is advisable to use probiotics containing strains only with proven beneficial effect. The efficiency of preparations containing mixed strains has not yet been properly investigated. The author reviews the rare but potentially serious side effects of probiotics. In Hungary, there are many probiotic preparations available which can be purchased in pharmacies without prescription: their use is more empirical than evidence-based. The European Food Safety Authority has recently rejected claims for probiotics to be classed as medicines given the lack of convincing evidence on the effects of probiotics on human health and well-being. Clearly, further research is needed to collect evidence which could be incorporated into the international guidelines. Orv. Hetil., 2013, 154, 294–304.

Background and Aims: A number of significant positive and negative signals emerged from the CANVAS Program and CREDENCE trial with the use of canagliflozin. These signals are confusing. A Likelihood of being Helped of Harmed (LHH) analysis was conducted to determine the risk, benefit ratio associated with canagliflozin use and address the signals as a continuum. Materials &Methods: LHH was calculated from the number needed to treat (NNT) and number needed to harm (NNH) available from the absolute risk reductions reported with the outcomes of interest, in these two trials. Results: In the CANVAS Program, LHH for major adverse cardiovascular events (MACE) points at a significant benefit with canagliflozin use in comparison to amputation (1.65), fractures (1.65) and euglycaemic diabetic ketoacidosis (euDKA) (16.67) risks. Only genital fungal infections were significant more in both sexes (0.21-M and 0.1-F) when LHH was matched against the positive outcomes. In contrast, the hHF benefits were outweighed by amputation (0.95) and fracture risks (0.95). : In CREDENCE trial, the LHH for Primary composite, Renal composite and MACE, all supported the benefits in comparison to any adverse events encountered in the trial. : The LHH from pooled data (CANVAS Program and CREDENCE trial) was in favour of all the benefits (hHF and renal composites) except for MACE matched against amputation (0.66). Conclusion: The outcome benefits were in favour of canagliflozin in comparison to all reported adverse events, when hHF and renal composite were under consideration, in both the individual and pooled LHH analysis. However, the MACE benefits were overwhelmed by amputation risk in the pooled analysis.

Background: The signal is defined as “reported information on a possible causal relationship between an adverse event and a drug, of which the relationship is unknown or incompletely documented previously”. Objective: To detect novel adverse events of iloperidone by disproportionality analysis in FDA database of Adverse Event Reporting System (FAERS) using Data Mining Algorithms (DMAs). Methodology: The US FAERS database consists of 1028 iloperidone associated Drug Event Combinations (DECs) which were reported from 2010 Q1 to 2016 Q3. We consider DECs for disproportionality analysis only if a minimum of ten reports are present in database for the given adverse event and which were not detected earlier (in clinical trials). Two data mining algorithms, namely, Reporting Odds Ratio (ROR) and Information Component (IC) were applied retrospectively in the aforementioned time period. A value of ROR-1.96SE>1 and IC- 2SD>0 were considered as the threshold for positive signal. Results: The mean age of the patients of iloperidone associated events was found to be 44years [95% CI: 36-51], nevertheless age was not mentioned in twenty-one reports. The data mining algorithms exhibited positive signal for akathisia (ROR-1.96SE=43.15, IC-2SD=2.99), dyskinesia (21.24, 3.06), peripheral oedema (6.67,1.08), priapism (425.7,9.09) and sexual dysfunction (26.6-1.5) upon analysis as those were well above the pre-set threshold. Conclusion: Iloperidone associated five potential signals were generated by data mining in the FDA AERS database. The result requires an integration of further clinical surveillance for the quantification and validation of possible risks for the adverse events reported of iloperidone.

In light of positive efficacy and safety findings from the IMbrave150 trial of atezolizumab plus bevacizumab, this novel combination has become the preferred first-line standard of care for patients with unresectable hepatocellular carcinoma (HCC). Several additional trials are ongoing that combine an immune checkpoint inhibitor with another agent such as a multiple kinase inhibitor or antiangiogenic agent. Therefore, the range of first-line treatment options for unresectable HCC is likely to increase, and healthcare providers need succinct information about the use of such combinations, including their efficacy and key aspects of their safety profiles. Here, we review efficacy and safety data on combination immunotherapies and offer guidance on monitoring and managing adverse events, especially those associated with atezolizumab plus bevacizumab. Because of their underlying liver disease and high likelihood of portal hypertension, patients with unresectable HCC are at particular risk of gastrointestinal bleeding, and this risk may be exacerbated by treatments that include antiangiogenic agents. Healthcare providers also need to be alert to the risks of proteinuria and hypertension, colitis, hepatitis, and reactivation of hepatitis B or C virus infection. They should also be aware of the possibility of rarer but potentially life-threatening adverse events such as pneumonitis and cardiovascular events. Awareness of the risks associated with these therapies and knowledge of adverse event monitoring and management will become increasingly important as the therapeutic range broadens in unresectable HCC.

Epithelioid angiosarcoma is a rare and highly aggressive soft tissue angiosarcoma most commonly arising in the deep soft tissues. Given that abundant vascular cavities anastomose with each other, most angiosarcomas prone to metastasis recur quickly, and the overall prognosis is poor. We report a 25-year-old woman at 24 weeks’ gestation who presented with a 1-month history of abdominal distension. Ultrasonography suggested a mass in the right adnexa, and she underwent two operations owing to uncontrolled intraperitoneal bleeding with progressive anemia. The right ovarian tumor and right adnexa were removed successively. Biopsy yielded a diagnosis of primary epithelioid angiosarcoma with mature cystic teratoma. The patient died from uncontrolled progressive bleeding 1 week after the second operation. This case revealed that epithelial angiosarcoma is a highly malignant endothelial cell tumor. The results of surgery and chemoradiotherapy tend to be poor, and the recurrence rate is high. The purpose of this study is to raise clinical awareness of epithelial angiosarcoma and its adverse events and to provide new ideas for the treatment of these adverse events. Immunohistochemical staining of pathological specimens can facilitate diagnosis. Pregnancy with malignant tumors may lead to rapid disease progression, extensive lesions, and a poor prognosis.

Abstract Background High-dose rifampicin may improve outcomes of tuberculous meningitis (TBM). Little safety or pharmacokinetic (PK) data exist on high-dose rifampicin in HIV co-infection, and no cerebrospinal fluid (CSF) PK data exist from Africa. We hypothesized that high-dose rifampicin would increase serum and CSF concentrations without excess toxicity. Methods In this phase II open-label trial, Ugandan adults with suspected TBM were randomised to standard-of-care control (PO-10, rifampicin 10mg/kg/day), intravenous rifampicin (IV-20, 20mg/kg/day), or high-dose oral rifampicin (PO-35, 35mg/kg/day). We performed PK sampling on day 2 and 14. The primary outcomes were total exposure (AUC0-24), maximum concentration (Cmax), CSF concentration and grade 3-5 adverse events. Results We enrolled 61 adults, 92% were HIV-positive, median CD4 count was 50cells/µL (IQR 46–56). On day 2, geometric mean plasma AUC0-24hr was 42.9h.mg/L with standard-of-care 10mg/kg dosing, 249h.mg/L for IV-20 and 327h.mg/L for PO-35 (P<0.001). In CSF, standard-of-care achieved undetectable rifampicin concentration in 56% of participants and geometric mean AUC0-24hr 0.27mg/L, compared with 1.74mg/L (95%CI 1.2–2.5) for IV-20 and 2.17mg/L (1.6–2.9) for PO-35 regimens (p<0.001). Achieving CSF concentrations above rifampicin minimal inhibitory concentration (MIC) occurred in 11% (2/18) of standard-of-care, 93% (14/15) of IV-20, and 95% (18/19) of PO-35 participants. Higher serum and CSF levels were sustained at day 14. Adverse events did not differ by dose (p=0.34) Conclusion Current international guidelines result in sub-therapeutic CSF rifampicin concentration for 89% of Ugandan TBM patients. High-dose intravenous and oral rifampicin were safe, and respectively resulted in exposures ~6- and ~8-fold higher than standard-of-care, and CSF levels above the MIC

Abstract Background Canavan disease (CD, MIM # 271900) is a rare and devastating leukodystrophy of early childhood. To identify clinical features that could serve as endpoints for treatment trials, the clinical course of CD was studied retrospectively and prospectively in 23 CD patients. Results were compared with data of CD patients reported in three prior large series. Kaplan Meier survival analysis including log rank test was performed for pooled data of 82 CD patients (study cohort and literature patients). Results Onset of symptoms was between 0 and 6 months. Psychomotor development of patients was limited to abilities that are usually gained within the first year of life. Macrocephaly became apparent between 4 and 18 months of age. Seizure frequency was highest towards the end of the first decade. Ethnic background was more diverse than in studies previously reported. A CD severity score with assessment of 11 symptoms and abilities was developed. Conclusions Early hallmarks of CD are severe psychomotor disability and macrocephaly that develop within the first 18 months of life. While rare in the first year of life, seizures increase in frequency over time in most patients. CD occurs more frequently outside Ashkenazi Jewish communities than previously reported. Concordance of phenotypes between siblings but not patients with identical ASPA mutations suggest the influence of yet unknown modifiers. A CD severity score may allow for assessment of CD disease severity both retrospectively and prospectively.
