Introduction The most common kind of leukemia in adults is chronic lymphocytic leukemia (CLL). CLL is treated with ibrutinib. During the course of ibrutinib therapy, bleeding and cardiac arrhythmias may occur. Non-hemorrhagic adverse events are extremely infrequent in individuals using ibrutinib. Case report A 64 year-old man was diagnosed with CLL in June 2016. He was treated with 6 courses of FCR, he stayed in remission for 3 years and then relapsed. He achieved partial remission after two months of therapy with ibrutinib. The patient was admitted to the hospital with fever and shortness of breath. Pericardial tamponade and effusion was diagnosed during his evaluation. Management & outcome Non-hemorrhagic exudative effusion was drained by pericardiocentesis and a pericardial catheter was inserted to drain pericardial effusion. In all pleural and pericardial effusion samples, pathological and flow cytometric examination revealed no atypical malignant cells for malignancy, including CLL. Infections, both bacterial and viral, were also undetectable in the samples, as were rheumatological markers of collagen vascular disease. Ibrutinib therapy was discontinued. The pericardial effusion and tamponade were linked to ibrutinib treatment after evaluating the adverse drug reaction probability scale with a total score of 6. Colchicine was administered to reduce the pericardial effusion. The catheter was removed; pericardial effusion did not reoccur during follow up visits. Discussion Serious adverse events of ibrutinib are seen when treating CLL patients. This group of individuals should be closely monitored for potentially serious complications such as pericardial effusion and cardiac tamponade.

Nasal Valve Collapse

AbstractThe aim of the study is to report outcomes after treatment of nasal valve collapse with a bioabsorbable nasal implant. It involves two prospective, multicenter, post-market studies evaluating long-term effectiveness of the LATERA implant for severe to extreme nasal obstruction. Participants underwent implant alone or with concomitant inferior turbinate reduction (ITR) and/or septoplasty. Outcome measures included the change from baseline Nasal Obstruction Symptom Evaluation (NOSE) scores, NOSE responder rates, visual analog scale (VAS) scores, and adverse events. A total cohort of 277 participants (109 implants only, 67 implants + ITR, 101 implants + septoplasty + ITR) enrolled at 19 U.S. centers was available for analysis with 177 participants (69 implants only, 39 implants + ITR, 69 implants + septoplasty + ITR) available at 2 years. The mean changes from baseline in NOSE scores and VAS scores were statistically significant (p < 0.001) at all follow-up periods. The baseline NOSE score of 77.8 ± 13.6 was improved to 24.2 ± 23.6 at 24 months. Greater than 90% of participants were NOSE responders across all follow-up periods, 6.1% withdrew for lack of treatment effect. The baseline VAS score of 66.7 ± 18.8 was improved to 21.1 ± 23.9 at 24 months. There were no serious adverse events related to the device or implant procedure. Implant retrieval rate was 4.0% (22/543 implants). Nonserious adverse events were mild to moderate in severity, typically occurred within 6 months of implant, and resolved or were stable. Significant reductions in NOSE and VAS scores and high responder rates from our large population of patients with nasal obstruction who had nasal valve implants confirm sustained effectiveness at 24 months after treatment. The studies are registered on www.clinicaltrials.gov (NCT02952313 and NCT02964312).

Background:Experts emphasize early diagnosis and treatment in RA, but the widely used diagnostic criterias fail to meet the accurate judgment of early rheumatoid arthritis. In 2012, Professor Zhanguo Li took the lead in establishing ERA “Chinese standard”, and its sensitivity and accuracy have been recognized by peers. However, the optimal first-line treatment of patients (pts) with undifferentiated arthritis (UA), early rheumatoid arthritis (ERA), and rheumatoid arthritis (RA) are yet to be established.Objectives:To evaluate the efficacy and safety of Iguratimod-based (IGU-based) Strategy in the above three types of pts, and to explore the characteristics of the effects of IGU monotherapy and combined treatment.Methods:This prospective cohort study (ClinicalTrials.gov Identifier NCT01548001) was conducted in China. In this phase 4 study pts with RA (ACR 1987 criteria[1]), ERA (not match ACR 1987 criteria[1] but match ACR/EULAR 2010 criteria[2] or 2014 ERA criteria[3]), UA (not match classification criteria for ERA and RA but imaging suggests synovitis) were recruited. We applied different treatments according to the patient’s disease activity at baseline, including IGU monotherapy and combination therapies with methotrexate, hydroxychloroquine, and prednisone. Specifically, pts with LDA and fewer poor prognostic factors were entered the IGU monotherapy group (25 mg bid), and pts with high disease activity were assigned to combination groups. A Chi-square test was applied for comparison. The primary outcomes were the proportion of pts in remission (REM)or low disease activity (LDA) that is DAS28-ESR<2.6 or 3.2 at 24 weeks, as well as the proportion of pts, achieved ACR20, Boolean remission, and good or moderate EULAR response (G+M).Results:A total of 313 pts (26 pts with UA, 59 pts with ERA, and 228 pts with RA) were included in this study. Of these, 227/313 (72.5%) pts completed the 24-week follow-up. The results showed that 115/227 (50.7%), 174/227 (76.7%), 77/227 (33.9%), 179/227 (78.9%) pts achieved DAS28-ESR defined REM and LDA, ACR20, Boolean remission, G+M response, respectively. All parameters continued to decrease in all pts after treatment (Fig 1).Compared with baseline, the three highest decline indexes of disease activity at week 24 were SW28, CDAI, and T28, with an average decline rate of 73.8%, 61.4%, 58.7%, respectively. Results were similar in three cohorts.We performed a stratified analysis of which IGU treatment should be used in different cohorts. The study found that the proportion of pts with UA and ERA who used IGU monotherapy were significantly higher than those in the RA cohort. While the proportion of triple and quadruple combined use of IGU in RA pts was significantly higher than that of ERA and UA at baseline and whole-course (Fig 2).A total of 81/313 (25.8%) pts in this study had adverse events (AE) with no serious adverse events. The main adverse events were infection(25/313, 7.99%), gastrointestinal disorders(13/313, 4.15%), liver dysfunction(12/313, 3.83%) which were lower than 259/2666 (9.71%) in the previous Japanese phase IV study[4].The most common reasons of lost follow-up were: 1) discontinued after remission 25/86 (29.1%); 2) lost 22/86 (25.6%); 3) drug ineffective 19/86 (22.1%).Conclusion:Both IGU-based monotherapy and combined therapies are tolerant and effective for treating UA, ERA, and RA, while the decline in joint symptoms was most significant. Overall, IGU combination treatments were most used in RA pts, while monotherapy was predominant in ERA and UA pts.References:[1]Levin RW, et al. Scand J Rheumatol 1996, 25(5):277-281.[2]Kay J, et al.

Abstract Background Endoscopic cyanoacrylate (glue) injection of fundal varices may result in life-threatening embolic adverse events through spontaneous gastrorenal shunts (GRSs). Balloon-occluded retrograde transvenous occlusion (BRTOcc) of GRSs during cyanoacrylate injection may prevent serious systemic glue embolization through the shunt. This study aimed to evaluate the efficacy and safety of a combined endoscopic–interventional radiologic (BRTOcc) approach for the treatment of bleeding fundal varices. Methods We retrospectively analysed the data of patients who underwent the combined procedure for acutely bleeding fundal varices between January 2010 and April 2018. Data were extracted for patient demographics, clinical and endoscopic findings, technical details, and adverse events of the endoscopic–BRTOcc approach and patient outcomes. Results We identified 30 patients (13 [43.3%] women; median age 58 [range, 25–92] years) with gastroesophageal varices type 2 (53.3%, 16/30) and isolated gastric varices type 1 (46.7%, 14/30) per Sarin classification, and median clinical and endoscopic follow-up of 151 (range, 4–2,513) days and 98 (range, 3–2,373) days, respectively. The median volume of octyl-cyanoacrylate: Lipiodol injected was 7 (range, 4–22) mL. Procedure-related adverse events occurred in three (10.0%) patients, including transient fever, non-life-threatening pulmonary glue embolism, and an injection-site ulcer bleed. Complete gastric variceal obturation was achieved in 18 of 21 patients (85.7%) at endoscopic follow-up. Delayed variceal rebleeding was confirmed in one patient (3.3%) and suspected in two patients (6.7%). Although no procedure-related deaths occurred, the overall mortality rate was 46.7%, primarily from liver-disease progression and co-morbidities. Conclusion The combined endoscopic–BRTOcc procedure is a relatively safe and effective technique for bleeding fundal varices, with a high rate of variceal obturation and a low rate of serious adverse events.

Abstract Background Alemtuzumab is an effective disease-modifying therapy (DMT) for highly active multiple sclerosis (MS). However, safety concerns limit its use in clinical practice. Objectives To evaluate the safety of alemtuzumab in a nationwide cohort of Finnish MS patients. Methods In this retrospective case series study, we analyzed the data of all but two MS patients who had received alemtuzumab in Finland until 2019. Data were systematically collected from patient files. Results Altogether 121 patients were identified, most of whom had received previous DMTs (82.6%). Median follow-up time after treatment initiation was 30.3 months and exceeded 24 months in 78 patients. Infusion-associated reactions (IARs) were observed in 84.3%, 57.3%, and 57.1% of patients during alemtuzumab courses 1–3, respectively. Serious adverse events (SAEs) were observed in 32.2% of patients, serious IARs in 12.4% of patients, and SAEs other than IARs in 23.1% of patients. Autoimmune adverse events were observed in 30.6% of patients. One patient died of hemophagocytic lymphohistiocytosis, and one patient died of pneumonia. A previously unreported case of thrombotic thrombocytopenic purpura was documented. Conclusions SAEs were more frequent in the present cohort than in previous studies. Even though alemtuzumab is a highly effective therapy for MS, vigorous monitoring with a long enough follow-up time is advised.

Background: Valsartan is an established drug for treatment of essential hypertension. It blocks the action of Angiotensin II irrespective of its sources. A large proportion of patients need additional treatment with two or more drugs of different pharmacological classes for achieving target blood pressure. Published evidence demonstrated synergistic effect of Thiazides with ARB. Coadministration of valsartan and Hydrochlorothiazide has the potential to reverse the untoward effect of each other. Current study aimed at evaluating the efficacy, safety and tolerability of Valsartan plus Hydrochlorothiazide combination, and thus validating the regimen in the treatment of essential hypertension in Bangladeshi population, a population significantly different from Caucasian population where most studies were done. Methods: Current study is a prospective interventional study involving 404 Adult, patients, with Stage I (SBP 140-159 mmHg/DBP 90-99 mmHg) or Stage II (SBP≥160 mmHg/DBP ≥100 mmHg) essential hypertension or patients uncontrolled on current mono-therapy or other combination therapy. Valsartan plus HCTZ 80/12.5 mg once daily tablet were prescribed to continue till the following visit or for the remainder of the study. In case of inadequate control increment in dose was made on the following visit. Patients were assessed at baseline, at 4th weeks, 12th week and 24th week. One of the major outcome parameter set for the study was the percentage of participant having BP controlled that is a SBP <140 mmHg and DBP <90 mmHg or a reduction >10 mmHg for DBP and/ or >20 mmHg SBP versus baseline values at 24 weeks. At final follow-up, in addition to repetition of the baseline measurements and examinations, data on Safety of the drug was collected by enquiring and recording all adverse events or serious adverse events. Global assessment of efficacy and tolerability of treatment was also done by both the physicians and patients on a 4-point scale. Result: The percentage of participant having BP controlled at the end of the trial was 91%. Besides, Significant reduction in mean SBP and mean DBP was also evident (P<.001) through paired comparison from baseline to end of the study. Average reduction of 32.4 ± 19.5 mmHg was seen in systolic BP and 17.4 ± 9.3 mmHg in diastolic BP. Global assessment based on both physician and patients reported greater satisfaction with the efficacy of treatment modality. Total adverse event reported by only six (1.5%) participants. Of the six cases three of the adverse effect was reported at 3rd visit and another three were reported at 4th visit. Total five dropouts (1.24%) were reported of which 1 in 3rd visit and 4 in 4th visit. Among the dropout patient three were withdrawn from the study and two didn’t attend the final follow-up. Global assessment of safety and tolerability based on both physician and patient’s opinion reveals greater satisfaction level with the safety and tolerability of combination treatment. Conclusion: The combination of valsartan and hydrochlorothiazide is an effective treatment for patients with essential hypertension. The combination is also effective in patients not responding to monotherapy with either agent. The drug is found to be well tolerated with minimal adverse event during the course of treatment.

Vaccines against Coronavirus Disease 2019 Originated-19) have been developed with unprecedented rapidity, many utilizing novel strategies. As of November 2020, a series of publications have outlined the results of phase 1/2 studies of nine different vaccines planned to move forward to phase 3 trials. The results are encouraging, demonstrating a paucity of severe or serious adverse events and robust induction of antibody titers. Determination of the vaccine candidates with the highest protective efficacy and best adverse event profiles will be essential in refining public health strategies. However, differences in study design and reporting of data make comparisons of existing phase 1/2 studies difficult. With respect to safety, studies have variable follow-up times and may use different definitions for adverse events. Immunogenicity outcomes are even more inconsistent, with variations in timepoints and critical differences in the types of antibodies studied as well as methodological differences in assays. Furthermore, the correlates of protection in COVID-19 are not known. Harmonization of phase 3 trial designs and use of objective and meaningful clinical outcomes will be crucial in streamlining future global responses to the pandemic.

Abstract Introduction A 72-year-old lady presented with one-week history of palpitation and shortness of breath. She had pyrexia of unknown origin for 4 weeks associated with weight loss. Initial clinical examination revealed sinus tachycardia of 110 beats/min and saturations of 96% on 2L/min oxygen. Neck exam revealed a 2 x 3 cm firm mass at left supraclavicular fossa. Electrocardiogram showed sinus tachycardia at 106 beats/min. There was fixed T wave inversions over anterolateral chest leads and inferior limb leads. Chest radiograph showed enlarged cardiac silhouette and evidence of pulmonary congestion Procedure Transthoracic echocardiogram revealed a moderate pericardial effusion with an 8 x 4 cm pericardial mass compressing at the right atrioventricular groove (Figure B & C). Respiratory variation of Doppler mitral and tricuspid inflow velocities suggested cardiac tamponade (Figure A). Inferior vena cava was engorged with impaired inspiratory collapse. Left ventricular size and function were otherwise normal. Urgent pericardiocentesis was performed which yielded 1 litre of light blood stained fluid. Her had subjective improvement of symptoms. There was also resolution of sinus tachycardia and pulmonary congestion. PET/CT scan showed multiple enlarged hypermetabolic lymph nodes in multiple regions above and below the diaphragm, worrisome for malignant lymphoma. Cytological assessment of pericardial fluid showed scattered large lymphoid cells which are immunoreactive to B cell marker CD 20 (Figure E & F). Bone marrow exam showed normal marrow. First cycle of R-CEOP and intrathecal methotrexate was given. Follow-up echocardiogram in one week after chemotherapy showed complete resolution of pericardial effusion. Prior pericardial mass also showed marked reduction in size (Figure D). No tamponade physiology was present. She tolerated the chemotherapy well with complete resolution of palpitation and shortness of breath. She was discharged from hospital with outpatient follow up and continuation of chemotherapy course. Discussion Cardiac tumors are rare and secondary tumors remain the most common etiology. Most of these metastatic tumors arise from solid organs such as lung, breast, kidney, melanoma as well as lymphoma. Echocardiography is a valuable tool both in diagnosis and assessment of hemodynamic significance of cardiac masses. It also aids in diagnosis of associated condition such as pericardial effusion. In this case, the cardiac tamponade is both contributed by mechanical compression of cardiac mass coupled with moderate pericardial effusion. Successful pericardiocentesis achieved temporary normalization of tamponade physiology and aided in early histological diagnosis of malignant lymphoma with pericardial metastasis. Timely initiation of intensive systemic chemotherapy was the key to rapid tumor size reduction, complete resolution of tamponade physiology and control of recurrent pericardial effusion.

OBJECTIVE: To follow-up a report submitted to FDA Spontaneous Reporting System, we investigated the hypothesis that there was not a striking increase in unexpected deaths within four hours after elective coronary artery bypass surgery associated with protamine sulfate use. DESIGN: Surveys were mailed to clinical pharmacists at 521 hospitals participating in the Drug Surveillance Network. Questionnaires were to be completed with the assistance of cardiac surgeons and anesthesiologists. Hospitals responding with a suspected problem with protamine were contacted via telephone. RESULTS: Surveys were received from clinical pharmacists at 380 hospitals (73 percent response rate) and 29 hospitals reported the occurrence of potential problems associated with protamine during coronary artery bypass graft surgery. Telephone interviews of the positive responders yielded six cases of possible myocardial decomposition potentially associated with protamine. There was no association with a specific distributor, however, and none of the hospitals reported a dramatic increase in serious adverse events around the time of index cases. CONCLUSIONS: There was no evidence of a widespread public health problem with protamine and a product recall was not necessary. The high response rate and the ability to follow-up with telephone interviews suggests that the Drug Surveillance Network is an effective mechanism for investigating possible outbreaks of serious adverse events in the hospital setting.

Abstract Bcl-2 is an anti-apoptotic protein closely linked to chemotherapy resistance and inferior survival in patients (pts) with CLL. Genasense(GNS) enhances apoptosis induced by fludarabine (F), dexamethasone, and rituximab (R) in vitro, and has limited single-agent activity in heavily pre-treated CLL pts. Down-regulation of Bcl-2 may further sensitize CLL cells to apoptosis induced by F and R without exposing subjects to the toxicity of alkylating agents. CLL and NHL pts occasionally exhibit a “cytokine release syndrome” (spiking fever, back pain, and occasional hypotension) with GNS treatment. We hypothesized that a “step dosing” approach with GNS, similar to that sometimes used for R, could ameliorate these effects and allow safe and effective combination of this agent with F and R. We are currently evaluating this combination in pts with either previously untreated (UT) or relapsed, previously treated (PT) CLL who require systemic treatment. Eligibility includes: plts ≥ 50,000/mm3; serum Cr ≤ 1.5 mg/dL; adequate organ function; negative Coombs; no history of autoimmune hemolytic anemia. In cycle 1, GNS is given by continuous intravenous infusion at 1.5 mg/kg/d days 1 to 7. R is given on a dose-escalating schema (day 4, 125 mg/m2; day 6, 250 mg/m2). F (25 mg/m2/d) is given on days 6 to 8. In subsequent 28-day cycles (up to 6), the dose of GNS is escalated to 3 mg/kg/d days 1 to7 days, with R 375 mg/m2 on day 5 and F days 5 to7. To date, 20 pts have been enrolled (17 PT and 3 UT). Characteristics included: median age, 62 yrs (range 39 to 82 yrs); Rai stage III (2 pts) and IV (6 pts). Prior to administration of either F or R, single-agent GNS treatment at the initial reduced dose in Cycle 1 resulted in a median decrease in lymphocytes of 15% (among all patients regardless of decline in lymphocyte count) (Baseline: 48.3 cells x 103/ml; day 4: 40.1 cells x 103/ml). For the 13 pts who experienced a decline in lymphocyte count in cycle 1 prior to F and R, the median percentage change was 17%, with 4 pts having a &gt; 25% decrease. Three PT pts discontinued from study treatment prior to completing 6 cycles, 2 due to disease progression, and 1 with Grade 3 thrombocytopenia that was unresolved after 4 weeks. Among the 20 pts treated to date (9 ongoing), the most common grade 3 or higher adverse events have been neutropenia, pyrexia and thrombocytopenia. Serious adverse events have been noted in only 6 of 20 pts (all PT pts) and have included 2 pts with fever (1 neutropenic), 2 R infusion reactions, 1 lymph node abscess and 1 tumor lysis syndrome (with sepsis). Conclusions: 20 pts have been treated with combination GNS, F and R. Single-agent activity with GNS has been observed at a reduced dose of 1.5 mg/kg/d in cycle 1. The “step dosing” approach appears to be a well-tolerated, alternative approach to the administration of GNS. Further details of safety and efficacy will be presented.

Abstract Imatinib is an effective first line therapy for chronic myeloid leukemia (CML) and has substantially changed its biological and clinical behavior. Durable complete cytogenetic responses (CCyR) were reported in the majority of patients, with a rather benign side effect profile, despite the ‘off target’ inhibition of several other kinases, including Kit, PDGFR and Lck. Since available information is largely based on industry-sponsored trials and long-term field studies are lacking, the ILTE study was conceived as an industryindependent, academic, multicenter trial supported by the Italian Drug Safety Agency (AIFA). ILTE is an international study on a retrospective cohort and includes 31 centers in Europe, North/South America, Africa and Asia; therefore it is uniquely positioned to present a global picture of imatinib long-term effects. Consecutive patients with Ph+ CML who started imatinib between 01 September 1999 and 31 December 2004 were eligible if they were in Complete Cytogenetic Response (CCyR) after two years of imatinib treatment. Study endpoints were survival, serious adverse events (SAE, including second cancers), toxicities not qualifying as SAE (NSAE) but judged by the referring physician as substantially impacting quality of life, loss of CCyR, and development of PCR negativity. A total of 957 patients were enrolled, 92% of which met eligibility criteria. The median age of eligible patients was 50 (range 15–92) years; 59% of patients were males and the median follow-up was 3.1 years (excluding the first 2 years of treatment). As of Dec. 31 2007, 2564 person years were available for analysis. Eleven deaths were observed (only 3 of them caused by relapsed CML), with a standardized rate of 0.4/100 person years and an observed/expected ratio of 0.48 (95% CI = 0.24–0.85). One-hundred SAE were recorded (rate 3.9/100 person years, most frequent type “heart failure”), with 21% being considered related to imatinib. Second cancers were documented in 28 patients (rate 1.1/100 person years), with an observed/expected ratio of 1.27 (95% CI = 0.84–1.84). Among the 576 NSAE recorded (0.65/patient) the most frequent types were “edema, cramps, skin fragility, diarrhea”; 71% of them were related to imatinib. A total of 12 patients (1.4 %) discontinued imatinib because of toxicities during the period of observation. Thirty-four patients lost CCyR, corresponding to a rate of 1.4/100 person years (1.0 in patients with imatinib as first-line treatment, 1.5 in patients who were treated with imatinib &gt;6 months after diagnosis), with stable or increasing rates over time. Finally, 214 patients (24.5%) developed durable (&gt; 1 year) PCR negativity. In conclusion, the first report from ILTE shows that CML patients on imatinib die unfrequently of CML related causes, do not appear to have substantially higher second cancer rates than the general population, have mortality rates lower than expected in an age/sex matched population and do not show new types of imatinib-related adverse events. They also experience a low but steady rate of loss of CCyR and develop PCR negativity in approximately ¼ of cases. Follow-up and further analysis are ongoing.
