Abstract Both platelet count and function change after treatment of immune thrombocytopenia (ITP). Platelet function can be measured by plasma markers, including platelet activity (e.g. soluble P-selectin [sP-selectin] and soluble CD40 ligand [sCD40L]) and platelet turnover markers (e.g. glycocalicin [GC]). Patients were classified into no response (NR, including new diagnosis), partial response (PR) and complete response (CR). One hundred and sixteen samples (29 CR, 32 PR, and 55 NR) from 79 patients were collected. Plasma markers (sP-selectin, sCD40L and GC) were measured by ELISA. Platelet counts and mean platelet volume (MPV) were obtained in the clinical laboratory using GenS System-2. The results showed that responsive patients (PR + CR) had higher levels of sP-selectin (P = 0.026) and sCD40L (P = 0.001). Although there was no difference in MPV (P = 0.077) or GC (P = 0.078), there was a marked decrease of GC index (P < 0.001) in responsive patients. Paired sample analysis showed no difference in sP-selectin, sCD40L, MPV or GC but significant difference in GC index (P = 0.017) between NR and PR. Another paired sample analysis showed no difference in sP-selectin, sCD40L, MPV or GC but significant difference in GC index (P = 0.029) between PR and CR. Patients with refractory and newly diagnosed disease had significant difference in GC (P = 0.020) and sCD40L (P = 0.001), despite similarly low platelet counts. In conclusion, platelet activity markers (sP-selectin and sCD40L) and GC indices change in parallel with treatment response. Plasma levels of GC and sCD40L may be predictors of treatment response.

ABSTRACT BACKGROUND: Autoimmune hepatitis (AIH) is a chronic liver disease, characterized by necroinflammation and autoimmune etiology. Studies evaluating the characteristics of patients with AIH are scarce in Brazil. OBJECTIVE: Our objective was to evaluate the profile of patients with AIH in a specialized center in Southern Brazil and to verify factors related to treatment response. METHODS: this was a retrospective cohort study, which analyzed demographic, epidemiological, clinical, laboratory, and histologic data. Patients with AIH diagnosed according to the criteria of the International Autoimmune Hepatitis Group (IAIHG) were included. In liver biopsies, the degree of fibrosis, histological activity, presence of hepatocyte rosettes, plasma cell infiltrates, and confluent necrosis were evaluated. In the statistical analysis, the significance level was 5%. RESULTS: Forty adults patients diagnosed with AIH were included. The evaluated population predominantly consisted of women (75.0%) and the average age at diagnosis was 44.2 years. The association with extrahepatic autoimmune diseases occurred in 20.0% of cases. Clinically, 35.0% of patients presented with acute onset hepatitis, 37.5% with cirrhosis, and 27.5% with other forms of presentation. The most common clinical manifestation was jaundice (47.5%). Thirty-five patients were treated, and of these, 97.1% used prednisone combined with azathioprine. The average treatment time was 2.7 years. Response to treatment was complete or partial in 30 (85.7%) and absent in 5 (14.3%) patients. There was no statistically significant difference when evaluating response to treatment in relation to forms of presentation, histological findings, and the presence of autoantibodies. Regarding fibrosis, regression was observed in 18.75% of the cases. CONCLUSION: Most patients with AIH were young at presentation and of female sex. The association with extrahepatic autoimmune diseases and cirrhosis at presentation was seen in a considerable proportion of patients. Treatment was effective, but there were no clinical, histological or serological parameters capable of predicting treatment response.

Abstract Background Since the first case report of Gimaz et al., several investigators have reported that the secondary immune thrombocytopenia (ITP) can occur in patients with Helicobactor pylori (H. pylori) infection. Eradication of H. pylori has been shown to result in improvement in thrombocytopenia. In one systematic review of 696 patients with H. pylori infection it showed 50.3% overall response (platelet count >= 30 X 109/L and at least a doubling of the base line count) after H. pylori eradication. Under these results, ASH 2011 guidelines for ITP recommended that eradication therapy be administered in adult patients who are found to have H. pylori infection (grade 1b). But also they recommended that treatment be administered for newly diagnosed patients with a platelet count < 30 X 109/L. To the best of our knowledge, there was no prospective study to evaluate the efficacy of H. pylori eradication for ITP patient with moderate thrombocytopenia and positive H. pylori. In Korea, the prevalence of H. pylori was reported as high as 60 – 65% in general adult population. The response rate and price of 1st line triple regimen for H. pylori eradication were known to be 70 - 80% and around 100 US dollars in Korea. With these circumstances, tolerable treatment like H. pylori eradication for ITP patients with platelet count >=30 X 109/L is challengeable. Thus, we performed the prospective multicenter phase II study to evaluate the efficacy of H. pylori eradication for the 1st line treatment of persistent or chronic ITP patients with moderate thrombocytopenia. Methods We enrolled patients with persistent (3 to 12 months from diagnosis) or chronic (lasting for more than 12 months) ITP defined by international working group. The platelet counts of patients were between 30 X 109/L and 70 X 109/L. And all patients had positive result of C13-urea breath test (UBT) and had never been treated for ITP or H. pylori. Patients with other secondary ITP could not be enrolled. Patients received lansoprazole 30mg twice daily, amoxicillin 1000mg twice daily and clarithromycin 500mg, twice daily for one week. Eradication of H. pylori was evaluated at eighth week after treatment by UBT. Platelet counts were monitored at 2 weeks and after then at every month for a year. Complete response (CR) was defined as a platelet count >= 100 X 109/L. Partial response (PR) was defined as a platelet increase of >= 30 X 109/L and at least a doubling of the base line count. The primary endpoint was CR rate at 3 months after treatment. All patients provided written informed consents and this trial was registered at www.ClinicalTrials.gov (NCT01255332). Results Twenty-six patients were enrolled between November 2010 and May 2013 from 6 medical centers in Korea. Two patients with HCV infection and one patient with more than 70 X 109/L of platelet counts were excluded from analysis. The mean initial platelet counts of 23 patients (7 males, 16 females, median age 43 years and range 19 - 58 years) was 52.7 ± 9.5 X 109/L (range 39 – 68 X 109/L). All patients except one checked UBT after treatment and H. pylori eradication was achieved in 86.3% (19/22) of patients. CR was obtained in 13 of 23 patients (56.5%) within 3 months after treatment. And no PR was found until this time point. The median time to CR after initiating treatment was 4 weeks (range 2 – 8 weeks). CR rate of the patients who achieved H. pylori eradication was 63.2% (12/19). Unlike other reports, there was no significant difference on initial platelet counts among CR group and non-responder group and no significant correlation on the platelet levels between baseline and initial 3 months (Fig 1). Only 2 of 26 patients could not continue medication due to nausea and diarrhea, respectively. There was no other significant adverse event. Conclusion The eradication of H. pylori is an effective first line treatment for persistent or chronic ITP with moderate thrombocytopenia with high CR rate and rapid onset. And it has acceptable toxicity and relatively low cost. This study supports routine detection and eradication of H. pylori infection in ITP patients especially in populations with a high prevalence of this infection.

Introduction: Inflammatory Breast Cancer (IBC) is a rare and very aggressive breast cancer with poor prognosis. The prevalence is different from a country to another. In Tunisia, it is about 5 to 7% of breast cancer. The aim of this study is to describe the epidemiological and histopathological features of patients with inflammatory breast cancer and to evaluate the treatment response according to the molecular subtypes. Methods: This retrospective review identified 31 patients with no metastatic IBC treated in our radiotherapy department between December 2019 and November 2020. IBC was confirmed using the clinical criteria. Baseline clinic-pathological and treatment information was retrieved from medical records. Statistical analysis was performed with IBM SPSS V.20. Results: Median age was 51.3 years [27-68]. 48% of tumors were grade 3. The average tumor size was 36mm [10-90]. The histological type was ductal carcinoma in 97%. Vascular invasion was noted in 24 patients (77%). Thirty patients were classified as stage IIIB and one patient was IIIC. 74% were hormone receptor positive and 45% were HER2 positive. Luminal B was the predominant subtype (52%) followed by Her2 positive (32%), Luminal A (23%), and triple negative (3%) All patients had chemotherapy: neoadjuvant for 26 patients (84%) and adjuvant for 5 patients (16%). Nine patients (29%) had tumor pathological complete response (pCR). Partial response was observed in 18 patients (58%). Lymph node pCR was noted in 16% of cases (n=5). Endocrine therapy and trastuzumab were given to 76% and 45% of patients, respectively. The influence of the molecular subtype was not statistically significant on the response to neoadjuvant treatment. The highest rate of pCR were 43% for Her2positive, then 27%, 21% and 9% for Luminal B, Luminal A and Triple negative, respectively (p=0.2). Conclusion: Our study showed a high percentage of hormone receptor and Her2+ (74% and 45% respectively) in IBC. Luminal B was the most frequent subtype. Anthracycline-based chemotherapy and trastuzumab improved the pCR rate: 44% for Her2positive. Triple negative showed poorer pCR than other breast cancer subtype without a significant difference. A larger study is warranted to confirm our findings.

Abstract Background High-resolution computed tomography (HRCT) has proved to be an important diagnostic tool throughout the COVID-19 pandemic outbreaks. Increasing number of the infected personnel and shortage of real-time transcriptase polymerase chain reaction (RT-PCR) as well as its lower sensitivity made the CT a backbone in diagnosis, assessment of severity, and follow-up of the cases. Results Two hundred forty patients were evaluated retrospectively for clinical, laboratory, and radiological expression in COVID-19 infection. One hundred eighty-six non-severe cases with home isolation and outpatient treatment and 54 severe cases needed hospitalization and oxygen support. Significant difference between both groups was encountered regarding the age, male gender, > 38° fever, dyspnea, chest pain, hypertension, ≤ 93 oxygen saturation, intensive care unit (ICU) admission, elevated D-dimer, high serum ferritin and troponin levels, and high CT-severity score (CT-SS) of the severe group. CT-SS showed a negative correlation with O2 saturation and patients’ outcome (r − 0.73/p 0.001 and r − 0.56/p 0.001, respectively). Bilateral peripherally distributed ground glass opacities (GGOs) were the commonest imaging feature similar to the literature. Conclusion Older age, male gender, smoking, hypertension, low O2 saturation, increased CT score, high serum ferritin, and high D-dimer level are the most significant risk factors for severe COVID-19 pneumonia. Follow-up of the recovered severe cases is recommended to depict possible post COVID-19 lung fibrosis.

Background:Musculoskeletal Ultrasonography (MSUS) is now a widely used tool for monitoring of rheumatoid arthritis (RA). Although there are many proposed sets of composite scores, a fixed set of joints may not be an ideal tool to assess a disease like RA, which affects many joints and tendons in different presentations. In previous study (1) U9 score was proven to be correlated with disease activity parameters.Objectives:To determine whether US assessment using U9 score is useful for monitoring response to treatment for RA or not?Methods:A prospective, multicenter study were conducted in period from July 2019 to December 2019. All recruited RA patients were subjected to: Disease activity assessment by clinical disease activity indices (CDAI and DAS28 ESR). Functional status assessment by (HAQ) and ultrasonographic assessment using U9 score which include 8 joints (bilateral wrists,2ndMCP,3RDMCP and knees) plus most clinically affected joint or tendon (one joint or one tendon). Most clinically affected joints from 48 joints. Any affected tendons could be choosing. All targeted joints were evaluated according to EULAR guidlines and by EULAR/ OMERACT combined score (0-3). Targeted tendons were scored (0-3).All patients received their treatment (biologic and non biologic DMARDs) according to the decision of the treating physicians. No specific therapy is needed. CDAI and DAS28 ESR, HAQ and U9 score were repeated after 3 months to detect the response to change after receiving the therapy.Results:One hundred and forty patients (23.6% were male) with mean age 39.26±11.30 were recruited from 4 tertiary referral university hospitals.There was a significant difference (<0.001) between the first and second visits as regards clinical, laboratory and ultrasonographic parameters. DAS 28 decreased form (5.29±1.21) to (3.95±0.99), ESR decreased from (42.12±15.24) to (26.84±12.32), HAQ2 improved from (0.652±0.350) to (0.510±0.237) and U9 total US score decreased from (13.56±5.18) to (8.02±4.28).There was significant correlation between U9 ultrasonographic score and clinical parameters at both visits (table 1).Table 1.correlation between U9 ultrasonographic score and clinical parameters.U9 at 1stvisitU9 at 2ndvisitDAS-28Pearson Correlation(P value)0.806<0.0010.790<0.001CDAIPearson Correlation(P value)0.787<0.0010.773<0.001HAQPearson Correlation(P value)0.431<0.0010.317<0.001We found that the most suitable cut-off value of U9 score to predict high disease activity was 11.5 (sensitivity 85.7% and specificity 80.6%), cut off value for moderate disease activity was 5.5(sensitivity 83.2% and specificity 88%) and cut off value for low disease activity was 3.5 (sensitivity of 83.3% and specificity 57.1%).

Background:The frequency of comorbidities has increased in spondyloarthritis patients compared to the general population. The effect of comorbidities on tumour necrosis factor alpha inhibitor (TNFi) drug retention and treatment response has not been well evaluated.Objectives:The purpose of this study to assess the impact of comorbidities on the first TNFi drug survival and treatment response in patients with axial spondyloarthritis (axSpA) registered in theTURKBIOdatabase.Methods:In this study, the frequency of comorbidities, disease activity scores at baseline and month 6 and drug retention were recorded in AxSpA patients iniating first TNFi treatment between 2011 and 2019. Kaplan Meier plot and log rank tests were used for drug survival analysis. Cox regression analysis with HR was performed to evaluate the correlation between comorbidities and drug survival.Results:There were 2428 patients with AxSpA (39.3% female) who used their first TNFi during the study period. Among them, a total of 770 (31%) had at least one comorbid disease. Hypertension was the most common comorbidity (9.7%), followed by the affective disorders (8%) and chronic lung disease (5.8%). The baseline characteristics of patients are shown in Table 1.The presence of any comorbidity did not impact the first TNFi retention (Figure 1). When comorbidities were analysed seperately, we found that only history of cerebrovascular event was negatively associated with drug retention rate (HR: 6.9, p:0.008). There was no statistically significant difference in Bath AS Disease Activity Index 50% (BASDAI50) response between patients with and without comorbidity at 6 months. Less axSpA patients with comorbidity achieved a ASDAS score ≤ 2.1 compared to patients without comorbidity at 6 months.Table 1.Baseline Characteristics of PatientsRadiographic Spondyloarthritis, n (%)2318 (95.5)Female, n(%)954 (39.3)Age, year42.2±11.8Age at diagnosis, years32.5± 11.3Age at initial TNFi, years39.4 ± 11.1Symptom duration, years9.7± 7.5Time to initial TNFi, years7±6.8HLA-B27- positivity, n (%)1144 (47.1)Smokers, n (%)1068 (44)Baseline BASDAI35.5±22.2Baseline ASDAS-CRP2.8±1.1Baseline CRP (mg/L)15.7±24.4VAS global patient46.6±28.7-Quantitative variables are presented as mean ± SD, and qualitative variables are presented as frequency and percentage-ASDAS-CRP, Ankylosing Spondylitis Disease Activity Score using C-reactive protein VAS, visual analogue scaleConclusion:The results of this study demonstrated that the presence of previous cerebrovascular event decreased the first TNFi survival in patients with axSpA.

Abstract Objective The interference of the hemoglobin variant (Hb J-Bangkok) was evaluated on 4 different glycated hemoglobin assays and compared with a reference immuno assay. Methods An overall test of coincidence of 2 least-squares linear regression lines was performed to determine whether the presence of Hb J-Bangkok caused a statistically significant difference in HbA1c results compared with a reference immuno assay. Statistical analysis was performed on the difference of the estimated average glucose calculated from HbA1c values and fasting plasma glucose in the Hb J-Bangkok variant group using the different detection systems. Deming regression analysis was used to determinate whether Hb J-Bangkok had a significant interference on HbA1c results using an HbA1c±10% relative bias at 6% and 9% HbA1c as evaluation limits. Results Turbidimetric inhibition immunoassay method, and enzymatic methods were not affected by Hb J-Bangkok. However, Hb J-Bangkok showed statistically significant interference to the two ion-exchange high-performance liquid chromatography methods. Conclusion When performing HbA1c tests, clinical laboratory personnel should identify the Hb variant and select the appropriate methods or use alternative indicators.

This study aims to determine whether there is a significant difference in stock prices, stock transaction volume and stock returns due to the COVID-19 pandemic (case study at PT. Agung Podomoro Land, Tbk). This research data was taken 90 days before and 90 days after the announcement of the first case of COVID-19 in Indonesia. The data was processed by paired sample t-test, using SPSS version 20. From the results of data processing, it was shown that there was a significant difference in stock prices before and after the announcement of the first case of covid-19 in Indonesia. This is indicated by a significance value of 0.000 < 0.05 where the stock price has decreased compared to before the Covid-19 case. Meanwhile, the volume of stock transactions also showed a significant difference with a significance value of 0.007 <0.05, where the volume of stock transactions after the announcement showed a decrease. Likewise, stock returns show a significant difference with a significance value of 0.025 < 0.05 where stock returns have decreased after the announcement of the first case of covid-10 in Indonesia.

Background: Chronic kidney disease (CKD) is well known to increase the risk of cardiovascular disease (CVD). However, there is limited knowledge about the association between CKD in persons living with HIV (PLWH) and CVD. We sought to investigate the prevalence and characteristics of CVD in PLWH with and without CKD at a large single center in South Florida. Methods: A retrospective chart review of 985 of PLWH from a Special Immunology clinic at a large center in South Florida between 2017-2019 was performed. Data on demographics, clinical, laboratory and diagnostic studies were obtained from electronic health records. Results: The prevalence of CKD in PLWH in our cohort was 11%. The group of CKD was older (58 vs. 51 years p<0.05), with significantly more men (66% vs. 53% p=0.012). The CKD cohort had increased rates of hypertension, coronary artery disease (CAD), heart failure, diabetes mellitus, and cerebrovascular disease (<0.05 for all). PLWH with CKD had a significantly higher HbA1C level, systolic and diastolic blood pressure, statin use, and lower LDL-C (p<0.05 for all). Subjects with HIV and CKD had a higher rate of cardiac catheterization (7.2%), with an increased rate of obstructive CAD (6.3%), when compared to PLWH without CKD (1.3% and 0.7%, respectively, p<0.05 for both). The rate of diastolic dysfunction was significantly higher in PLWH with CKD than those without CKD (p=0.004), although, no difference in ejection fraction (p=0.079) was noted. We found a significantly lower average CD4 count in individuals with HIV and CKD compared to those without CKD (483 ± 297 cells/mm 3 vs. 570 ± 342 cells/mm 3 , p=0.006). No significant difference was noted between groups in mean viral load, proportion with undetectable viral load, and use of antiretroviral medications. Prevalence of chronic hepatitis infection (B and/or C) was also higher in the CKD cohort (p<0.05). Conclusion: In this study, we found a comparable rate of CKD compared to age-matched patients from the general population. We found higher rates of traditional CVD risk factors and disease in the CKD cohort, without significant difference in HIV-related factors. This supports the importance of CVD risk factor optimization in this population.

SUMMARY OBJECTIVE To compare the complete blood counts, namely the plateletcrit (PCT) and Platelet-To-Lymphocyte Ratio (PLR) of healthy subjects and those with morbid obesity in the young population. METHODS We included 45 patients with morbid obesity (body mass index -BMI - greater than or equal to 45 kg/m2) and 45 healthy subjects (BMI less than or equal to 25 kg/m2) in our study. Blood samples were obtained from the participants following a 12-hour fasting period. Then we evaluated the levels of hemoglobin (Hb), hematocrit (HCT), red cell distribution width (RDW), mean platelet volume (MPV), white blood cell (WBC), PLR, platelet counts, and PCT in the complete blood count. RESULTS The morbid obesity group had significantly higher platelet counts and PCT values (p<0.001), and PLR values (p=0.033). The value of WBC was also higher in the obese group (p=0.001). MPV was lower in the obesity group but not statistically significant (p=0.815). No significant difference was found between hemoglobin and hematocrit values in these groups; but RDW valuewere higher and statistically significant in the obese group (p=0.001). CONCLUSION PLR or PCT may be more useful as a marker in determining an increased thrombotic state and inflammatory response in morbid obesity.
