ABSTRACT
Immunosuppressive drugs are used for treating coronavirus disease 2019COVID-19pneumonia. This study examined the current status of screening and monitoring patients with COVID-19 pneumonia treated with immunosuppressive agents for hepatitis B virusHBVreactivation. Of 123 patients whose hepatitis B surface antigen level was measured, 2 were HBsAg-positive. Antihepatitis B core/surface antibodies were measured in all 121 HBsAg-negative patients. HBV DNA was measured in 31 of 32 patients who were positive for either or both antihepatitis B core/surface antibodies. Of 34 patients requiring regular monitoring, only 4 were monitored. The HBV monitoring rate at the initiation of COVID-19 treatment was high. How-ever, HBV monitoring after COVID-19 treatment was difficult because most patients were transferred to other hospitals or had their treatment terminated.Copyright © 2022 Takeshi Matsui et al.
ABSTRACT
Background and Aim: Immunosuppressive agents (e.g., baricitinib [BAR], tricizumab [TCZ]) and steroids are used for treating coronavirus disease 2019 (COVID-19) pneumonia. These immunosuppressive agents are known to cause HBV reactivation. The current guidelines recommend HBV screening and HBV reactivation monitoring in Japan. However, the status of compliance among treated patients with COVID-19 pneumonia remains unclear. Herein, we report the status of compliance with the current guidelines on HBV reactivation. Method(s): We investigated the implementation of HBV screening and HBV reactivation monitoring for patients who received immunosuppressive agents in our hospital from April 2021 up to June 2021. Background factors related to the presence or absence of screening were analyzed. Result(s): There were 123 patients who received immunosuppressive agents in our hospital from April 2021 up to June 2021. The patients median age was 63 years old (31-95 years), and 90 patients were men. BAR/steroid therapy was given in 115 patients and TCZ/steroid therapy in 8 patients. Of the 123 patients in whom HBs antigen level was measured, 2 patients were positive for HBs antigen. Anti-HBc/ HBs antibodies were measured in all 121 HBsAg-negative patients according to the guidelines. Of 32 patients who were positive for either or both anti-HBc/HBs antibodies, HBV DNA was measured in 31 patients. Of 34 patients who required regular reactivation monitoring, 30 did not receive regular monitoring (6 died in the hospital, 11 were transferred to other hospitals, and 13 were terminated of their treatment early in the outpatient department of the hospital). Only 4 patients were monitored according to the guidelines. Of the 4 patients monitored, 1 was positive for HBs antigen and was given a nucleic acid analogue. In 1 patient, HBV DNA increased from signal-positive to 1.4 LIU/mL and then to 1.7 LIU/mL and nucleic acid analogue was started. The remaining 2 patients had undetectable HBV DNA or remained signal-positive. Conclusion(s): The HBV reactivation monitoring rate at the start of COVID-19 pneumonia treatment was high. However, HBV reactivation monitoring after the COVID-19 pneumonia treatment was difficult because most patients were transferred to other hospitals or had their treatment terminated.
ABSTRACT
Background: More than a year has passed since the first coronavirus vaccines were widely used. However, some healthcare workers are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) despite full vaccination. The immune effect of SARSCoV- 2 vaccines attenuates in a few months in contrast to other universal vaccines, such as the hepatitis B vaccine, which have an immune effect that lasts for a longer time. In addition, the neutralizing antibody (Ab) titers can be measured only in limited medical institutions. In this study, we aimed to investigate the factors that predict SARS-CoV-2 infection in healthcare workers after vaccination. Method(s): In this study, we enrolled one thousand one hundred and thirty-three healthcare workers (826 women, 307 men) after second inoculation of the BNT162b2 vaccine (Pfizer /BioNTech) in February- April 2021. Medical checkups and self-reported questionnaires were used to collect medical histories and demographic characteristics. The Alinity SARS-CoV-2 IgG II Quant (Abbott) quantitative IgG spike protein serology assay was examined in a cohort of participants 1, 4, 6 months after the second vaccination, and 1 month after the third vaccination of the BNT162b vaccine. Lower Ab titers were defined under median at each time point. The relationships between SARS-CoV-2 infection and these factors were analyzed. Result(s): The mean observation period was four hundred and fortyeight days. The median titers at 1, 4, 6 months after the second vaccination were 9293 U/mL (interquartile range [IQR], 5840-14392 U/mL), 1658 U/mL (IQR, 999-2676) and 832 U/mL (IQR, 523-1300), respectively. The risk factors for lower Ab titers were age (60 years older, odds ratio [OR], 2.08), presence of current illness (OR 1.52), smoking habit (OR 2.36), and no fever after the second vaccination (OR 2.44). The median titers at 1 month after the third vaccination was 13780 U/mL (IQR, 9085-22722), and the risk factor for lower Ab titers was hepatitis B surface Ab (HBsAb) negative (OR 1.38). The total 1-year cumulative infection rate was 4.9%. The median infection period was three hundred and twenty days (IQR, 298-365) after the second vaccination. The risk factors of infection were age (30 s and 40 s), and HBsAb negative. The 1-year cumulative infection rate of 30-40 s and other ages were 6.6% and 3.7%, respectively (p<0.01). The 1-year cumulative infection rate of HBsAb negative participants with 30-40 s and other age were 7.7% and 4.9%, respectively (p = 0.064), while that of HBsAb positive participants with 30-40 s and other age were 6.7% and 1.7%, respectively (p<0.01). Conclusion(s): HBsAb and age can become prognostic factors to be infected with SARS-CoV-2 after vaccination. Especially, HBsAb negative people under 50 years old should pay attention to SARSCoV- 2 infection even after second vaccination.
ABSTRACT
Background: ALG-000184 is a prodrug of ALG-001075, a novel, potent, pan-genotypic Class II CAM. CAMs are thought to have two mechanisms of action (MoA). The primary MoA affects pgRNA encapsidation resulting in inhibition of HBV DNA/RNA replication, as confirmed in CHB subjects receiving ALG-000184. The secondary MoA, which occurs at higher concentrations, regulates the establishment and replenishment of cccDNA, resulting in lowering of HBsAg, an effect that has not been reported to date with ALG- 000184. Method(s): ALG-000184-201 is a multi-part, multicenter, doubleblind, randomized, placebo-controlled study. In healthy volunteers (HVs), single doses up to 500 mg and multiple doses up to 250 mg were well tolerated with linear PK (Gane E., HBV TAG and APASL 2021). In treatment naive (TN) subjects with CHB, daily oral doses of 10-100 mg ALG-000184 for 28 days were well tolerated with linear PK and were associated with profound reductions of DNA/RNA regardless of HBeAg status or dose (Yuen MF, EASL 2022). Plasma exposures required to engage the secondary MoA are expected to be achieved at the 300 mg dose level. Data from a 300 mg cohort treated for 28 days are described here. Data from another ongoing cohort treated with 300 mg for 12 weeks will be presented at the conference. Result(s): Ten subjects were randomized to 300 mg ALG-000184 for 28 days and two to placebo. Two subjects randomized to ALG- 000184 were replaced due to missing data due to Covid-19 lockdown. Subjects were Asian, HBeAg positive, and genotype B or C. Mean baseline HBV DNA and RNA levels were 8.4 log10 IU/mL and 7.3 log10 copies/mL, respectively. One subject experienced a serious adverse event (AE) of pneumothorax>8 weeks after last dose which was considered unlikely related to study drug. No subjects prematurely discontinued study drug. All treatment emergent AEs were Grade <= 2 except for 4 Grade >= 3 alanine aminotransferase (ALT) elevations, which an independent ALT Flare Committee assessed as not related to study drug toxicity. PK was similar to HBeAg negative and HV cohorts following body weight adjustment. Subjects dosed with 300 mg ALG-000184 experienced mean declines of 4.0 log10 IU/mL and 2.6 log10 copies/mL in HBV DNA and RNA levels, respectively, at Day 28. Three of 7 evaluable subjects who received ALG-000184 had HBsAg declines>0.2 log10 IU/mL (0.23-0.78 log10 IU/mL). One subject receiving ALG-000184 had unquantifiable HBsAg throughout the study. Additionally, one HBeAg positive subject in a prior 100 mg cohort had plasma exposures equivalent to the 300 mg dose level and experienced a 0.5 log10 IU/mL HBsAg decline. Conclusion(s): In TN HBeAg positive CHB subjects, 300 mg ALG- 000184 for 28 days was well tolerated, exhibited predictable PK and resulted in rapid and substantial declines in HBV DNA and RNA. Notably, 3 of 7 evaluable subjects from this cohort experienced HBsAg declines of up to 0.78 log10 IU/mL. These data suggest that ALG-000184 can engage the secondary MoA of CAM II. Cohorts evaluating 300 mg over longer durations are planned or ongoing.
ABSTRACT
Background/Aims: The clinical course of hepatitis B virus (HBV) infection in individuals with HIV-1 coinfection is marked by accelerated disease progression. A tenofovir-containing antiretroviral regimen is recommended in most people with HIV-1/HBV-coinfection, but there have not been randomized studies of tenofovir disoproxil fumarate (TDF) vs tenofovir alafenamide (TAF) in treatment- naive HIV-1/HBV-coinfected individuals. We report primary endpoint results from a Phase 3 study comparing bictegravir/emtricitabine/ TAF (B/F/TAF) vs dolutegravir + emtricitabine/TDF (DTG + F/TDF) at Week (W)48 in participants initiating treatment for both viruses. Method(s): Adults with HIV-1/HBV coinfection were randomized 1:1 to initiate blinded treatment with B/F/TAF or DTG + F/TDF (with placebo). Primary endpoints were the proportion of participants with HIV-1 RNA<50 copies/mL (FDA Snapshot) and plasma HBV DNA<29 IU/mL (missing = failure) at W48. Noninferiority was assessed with 95% CI (12% margin). Secondary and other endpoints included change from baseline cluster of differentiation 4 (CD4) count, proportion with hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) loss/seroconversion, and alanine transaminase (ALT) normalization (AASLD criteria). Result(s): Participants (N = 243) were randomized and treated (B/F/ TAF [n = 121], DTG + F/TDF [n = 122]) from 11 countries in Asia, Europe, North, and Latin America. Baseline characteristics were median age of 32 years, 4.5% female, 88% Asian, 30% HIV-1 RNA>100,000 c/mL, 40% CD4<200 cells/lL, median HBV DNA 8.1 log10 IU/mL, 78% HBeAg+. At W48, B/F/TAF was noninferior to DTG + F/TDF at achieving HIV-1 RNA<50 copies/mL (95% vs 91%, difference 4.1%;95% CI -2.5%-10.8%;P = 0.21), with mean CD4 gains of + 200 and + 175 cells/lL, respectively. B/F/TAF was superior to DTG + F/TDF at achieving HBV DNA<29 IU/mL (63% vs 43%, difference 16.6%;95% CI 5.9%-27.3%;P = 0.0023). Participants treated with B/F/TAF vs DTG + F/TDF had numerically higher HBsAg loss (13% vs 6%;P = 0.059), HBeAg loss (26% vs 14%;P = 0.055), HBeAg seroconversion (23% vs 11%;P = 0.031), and ALT normalization (73% vs 55%;P = 0.066). The most frequent adverse events among participants treated with B/F/TAF vs DTG + F/TDF were upper respiratory tract infection (17% vs 11%), COVID- 19 (13% vs 11%), pyrexia (9% vs 12%), ALT increase (7% vs 11%), and nasopharyngitis (11% vs 4%). ALT flares (elevations at >= 2 consecutive postbaseline visits) occurred in 11 participants (7 B/F/ TAF, 4 DTG + F/TDF), and all resolved. Conclusion(s): Among adults with HIV-1/HBV-coinfection starting antiviral therapy, both B/F/TAF and DTG + F/TDF had high HIV-1 suppression at year 1, with B/F/TAF resulting in superior HBV DNA suppression and significantly more HBeAg seroconversion. Safety findings were similar between groups.
ABSTRACT
The severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) infection and associated (COVID-19) pandemic disrupted the healthcare systems of most countries because of the overwhelming demand for COVID-19 care and the ensuing diversion of resources and public attention to this purpose. The WHO goals for HBV and HCV elimination are thus facing major hurdles regarding both screening and treatment, and are at risk of failure. Because of the pandemic, hospital liver care departments have reallocated health professionals and reduced or suspended outpatient care. Hepatitis elimination programs and interventions (screening, diagnosis, and treatment) have been reduced or halted altogether. The Egyptian Liver Research Institute and Hospital (ELRIAH) reported a reduction during 2020 vs. 2019 of 57.0% for HCV consultations and 87.2% for new referrals. In addition, Requests for HCV RNA testing were greatly affected, with 60.7% reduction in HCV RNA test requests between 2019 and 2020 with a drop of 86.9% in the number of HCV RNA-positive patients detected. In terms of HCV treatment rates;86.2% fewer patients with HCV started on antiviral treatment during the pandemic period compared to the year before. Regarding HBV, the reduction between 2019 and 2020 was 43.7% for consultations and 7.3% for new referrals. As a consequence, the number of HBsAg-positive individuals observed in ELRIAH decreased by 8.7%. Also, the requests for HBV testing were found to be highly affected. Consequently, the number of patients with detectable HBV DNA dropped by 8.3% and HBV treatment rates also decreased. In conclusion, the COVID-19 pandemic has had a significant impact on every step of the viral hepatitis cascade of care. Furthermore, HCC surveillance programmes are mostly halted.

Risk Factor : Hypertension, diabetes mellitus O/E : Pale, cold and absent of radial, ulnar, brachial pulse of left upper limb. Muscle power 3/5 left side. So2 86%, BP undetectable. Right upper limb were normal. BP 160/90 mm of hg, pules : 112 b/min, RR : 26/min. Body Temperature 37.5 C [Formula presented] [Formula presented] Relevant Test Results Prior to Catheterization: CBC : WBC 7450, HB % 10.8 g/dl, ESR 20mm in 1st hour, Platelets : 262000, SARS Cov2 Antigen : Negative PT 14.3 sec, INR : 1.07 APTT : 32.4 sec. blood group: O positive Serum Creatinine : 1.1 mg/dl Plasma glucose 9.7 mmmol/l HIV Ab : Negative HBs Ag : Negative Anti-HCV : Negative Urine R/E : Normal lipid profile : Cholesterol 280mg/dl Vascular duplex ultrasound of left upper limb : A dilated echogenic thrombus had blocked the left subclaviav artery lumen. Relevant Catheterization Findings: Conventional angiography with the lowest amount of contrast agent through the right femoral artery, revealed that left subclavian artery thrombosis with total occlusion distal to Left internal mammary artery. [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: A5Fr MPA catheter with side holes was negotiated through a right femoral sheath and was placed in the left subclavian artery. Initially thrombus aspiration was done with Eliminate aspiration catheter (TERUMO) with no success. Then suction was done with the MPA catheter itself with partial removal of thrombus. Then a 5Fr Pigtail catheter was placed inside the thrombus and kept in situ. For residual thrombus 250,000u of Inj. Streptokinase as a thrombolytic drug was given through the Pigtail catheter as bolus over 30 min. The maintenance dose 100,000 u per hour was given over 24 hours through the Pigtail catheter via infusion pump. After 24 hours of thrombolytic therapy, her pain was reduced, the left hand became slightly warm, and distal pulses were feebly palpable. Moreover, the skin colour returned to near normal with improvement of pallor. Bleeding was well controlled at the catheter site. Doppler sounds revealed partial improvement of arterial flow. After evaluation of partial improvement, a low dose 1000 iu per hour of heparin (UFH)was infused intravenously for 24 hours. After 48 hours, repeat angiography via the inserted catheter at the site did not reveal any atherosclerotic plaque and confirm the thrombosis-dissolution. The latter practice demonstrated a good blood flowto the left upper distal limb leaving a little thrombus in the superficial palmer arch. [Formula presented] [Formula presented] [Formula presented] Conclusion(s): Catheter-based thrombus aspiration and thrombolytic therapy is primarily reserved for patients with acute viable limb ischemia. As observed in the presented case, thrombus aspiration and thrombolytic therapy is recommended to be considered as an alternative therapeutic method for patients with arterial thrombosis due to the rapid response, shorter treatment time and lower cost, compared to common and sometimes unsuccessful therapies.Copyright © 2023
ABSTRACT
Herbal plant extracts or purified phytocomponents have been extensively used to treat several diseases since ancient times. The Indian Ayurvedic system and Chinese traditional medicines have documented the medicinal properties of important herbs. In Ayurveda, the polyherbal formulation is known to exhibit better therapeutic efficacy compared to a single herb. This review focuses on six key ayurvedic herbal plants namely, Tinospora cordifolia, Withania somnifera, Glycyrrhiza glabra/Licorice, Zingiber officinale, Emblica officinalis and Ocimum sanctum. These plants possess specific phytocomponents that aid them in fighting infections and keeping body healthy and stress-free. Plants were selected due to their reported antimicrobial and anti-inflammatory effects in several diseases and effectiveness in controlling viral pathogenesis. An ad-vanced literature search was carried out using Pubmed and google scholar. Result(s): These medicinal plants are known to exhibit several protective features against various diseases or infections. Here we have particularly emphasized on antioxidant, anti-inflammatory, anti-microbial and immunomodulatory properties which are common in these six plants. Recent literature analysis has revealed Ashwagandha to be protective for Covid-19 too. The formulation from such herbs can exhibit synergism and hence better effectiveness against infection and related dis-eases. The importance of these medicinal herbs becomes highly prominent as it maintains the har-monious balance by way of boosting the immunity in a human body. Further, greater mechanistic analyses are required to prove their efficacy in fighting infectious diseases like Covid-19. It opens the arena for in-depth research of identifying and isolating the active components from these herbs and evaluating their potency to inhibit viral infections as polyherbal formulations.Copyright © 2023 Bentham Science Publishers.
ABSTRACT
Introduction: During armed conflicts dialysis patients may experience limitations or interruptions of therapy leading to severe life-threatening complications due to medical and logistical challenges. Before the Russian-Ukrainian war, there were approximately 10,000 adults requiring dialysis in Ukraine. Some patients decided to flee their place of residence and look for opportunities to continue dialysis in another location in Ukraine or abroad. To better understand the needs of conflict-affected kidney failure patients and to provide data which could support equitable and evidence-based prioritization of resources, the Renal Disaster Relief Task Force of the European Renal Association conducted a survey on distribution, preparedness and management of adults requiring dialysis displaced due to the war in Ukraine. Method(s): Cross-sectional online survey was conducted to assess the status of dialysis patients who were displaced across European countries since the beginning of the conflict in February 2022. The survey was sent to all national nephrology societies across Europe with a request to disseminate it to all dialysis centers in their countries. Data were collected between May and August 2022. Fresenius Medical Care (FMC) shared a limited set of aggregated data without direct center participation. Result(s): We received data on 602 patients (290 collected through the survey and 312 from FMC), who were dialyzed in 24 countries. Most patients were dialyzed in Poland (45.0%), followed by Slovakia (18.1%), Czech Republic (7.8%), Romania (6.3%), Germany (4.7%) and Hungary (3.5%). Most patients were originally dialyzed in Kyiv (north-central), Kharkiv (northeast), Odesa (southwest) and Zaporizhzhia (southeast). Before reaching the current reporting center, 34.6% of patients were treated in at least one other center since leaving their regular unit. Mean age was 48.1+/-13.4 years, 43.5% were females. Before patients left Ukraine, 95.7% had been on hemodialysis (HD), 2.5% on continuous ambulatory peritoneal dialysis (PD) and 1.8% on automated PD. HD session frequency was reduced under war conditions in 23.5% of patients. Eighty-eight percent of HD patients had a patent arteriovenous fistula, 7.3% were HBs antigen positive, 16.1% had anti-HCV antibodies, 0.6% anti-HIV antibodies and 27.3% anti-HBc antibodies. In terms of patient preparedness for displacement, 63.9% carried medical records with them, 63.3% had a list of medications, 60.4% had medications themselves and 44.0% had a dialysis prescription. Overall, 26.1% of patients were admitted to the dialysis unit in the possession of all these factors while 16.1% presented with none. After leaving Ukraine, 33.9% of patients were hospitalized. Of the 88.5% of patients tested in the reporting center for COVID-19 1.9% was positive. Communication and language problems were reported by 43.8% of responding physicians. Conclusion(s): Up to the end of August 2022, less than 10% of Ukrainian dialysis patients decided to flee their country since the start of the Russian-Ukrainian conflict and the majority of them chose as their place for dialysis a country neighboring Ukraine. Preparedness for displacement varied and was incomplete in most patients. Results from our survey may inform evidence-based policies and interventions to prepare for and respond to special needs of vulnerable kidney failure populations during armed conflicts and other emergencies.

ABSTRACT
Introduction: Access to kidney transplantation has always been a problem in the African countries with many patients having to travel to other medically advanced countries in Asia, Europe and America. This involves unnecessary excessive expenditure and the travails of journey and stay in an unknown foreign land. To ease this situation and to provide affordable Renal transplant services in their home land, we have made an effort to start the transplant services at our medical facility and have successfully carried out about 275 transplants over a period starting from Nov 2018 till September 2022. Method(s): All the Kidney transplants done between the period Nov 2018- September 2022 (275 cases) were included in the analysis. All the transplants were performed at a single center and the data were collected progressively during their Pre transplant evaluation, perioperative course and post op follow up. All the laboratory and radiological tests were done locally at the center except the HLA cross matches and tissue typing, which were outsourced to Transplant immunology labs outside the country. All the patients with positive DSA titres [about 70%], underwent Plasmapheresis and received IVIg before the transplantation. immunological assessment was done by NGS high resolution, for A B C DP DQ DR loci and X match was done by SAB analysis for class 1 and Class II antigens. All the patients underwent laparoscopic donor nephrectomy. All Patients received vaccinations for Hepatitis B, Pneumonia, Infuenza & Covid. Result(s): A series of 275 kidney transplants were performed over a period of 42 months [ Nov 2018- September 2022] at a private hospital successfully. All the cases were live donor kidney transplants with majority of the donors being 1st or 2nd degree relatives or spousal donors. About 70% of the patients had some degree of sensitization in the form of weakly positive B cell X match, or positive for DSAs at CL I, CLII with MFIs > 1000. All high-risk patients received induction with rabbit Thymoglobulin, and IV methyl prednisolone. Around 50 patients received Basiliximab. Of all patients, 4were HBsAg positive, and 6 were HIV positive,& HCV 1 patient. 8 patients required pretransplant Parathyroidectomy for refractory hyperparathyroidism, 3 patients required simultaneous native kidney nephrectomy at the time of transplant. 25 patients had multiple renal vessels which were double barreled and anastamosed.4 patients had lower urinary tract abnormalities requiring simultaneous/subsequent repair. Overall, 4 patients underwent 2nd transplant. All the donors underwent laparoscopic nephrectomy. Most of the patients had good immediate graft function except in 40 patients, who had delayed graft function;most of them improving over 2 - 6 weeks. 6 Patients had hyperacute rejection and the graft was lost,.4patients had main renal artery thrombosis, Renal allograft biopsy was done in 20 patients. Overall, the Patient survival was 95 %.at 1 year and graft survival 90%. Conclusion(s): Our experience shows that kidney transplantation is a viable and practical option for End stage kidney disease and can be performed even in resource constrained centers in third world countries and the survival rates of patients and the grafts are comparable to other centers across the world.

ABSTRACT
Aim: Transmission of SARS-CoV-2 infection can easily occur through direct or close contact with infected people, just as with other infectious diseases. Therefore, it is important to detect it prior to the intervention for protecting the health of both the healthcare worker and the patient. In the study, it was aimed to determine the seropositivity rates of acute respiratory syndrome coronavirus 2, hepatitis A, hepatitis B, hepatitis C virus and human immune deficiency virus infections among children who underwent gastrointestinal endoscopy. Material(s) and Method(s): The study was conducted at the Department of Pediatric Gastroenterology of the Karabuk University in Turkey from December 2020 to December of 2021. A total of 175 children were included in the study. The study was divided into three age groups as follows: 1-6 years old, 7-12 years old and 13-18 years old. All children were screened for acute respiratory syndrome coronavirus 2, hepatitis A, hepatitis B, hepatitis C virus and human immune deficiency virus infections. Result(s): The median age was 12.5 years (1-18). The seroprevalence of acute respiratory syndrome coronavirus 2, Anti-HAV IgM, Anti-HAV IgG, HBsAg, Anti-HBs, Anti-HCV, Anti-HIV and were detected 0.57%, 0.57%, 42.8%, 0%, 58.8%, 1.1% and 0 % respectively. The seroprevalence of Anti-HAV IgG was significantly higher in children aged 1-6 years than in the group aged 13-18 years (95.7 vs 25.2: chi2=48.1, p=0.001). Discussion(s): Although seroprevalence rates prior to endoscopy were low in this study, viral screening, except for hepatitis A infection, is essential for the safety of both patients and healthcare.Copyright © 2022, Derman Medical Publishing.

ABSTRACT
Plasmonic enhanced fluorescence (PEF) technology is a powerful strategy to improve the sensitivity of immunofluorescence microarrays (IFMA), however, current approaches to constructing PEF platforms are either expensive/time-consuming or reliant on specialized instruments. Here, we develop a completely alternative approach relying on a two-step protocol that includes the self-assembly of gold nanoparticles (GNPs) at the water-oil interface and subsequent annealing-assisted regulation of gold nanogap. Our optimized thermal-annealing GNPs (TA-GNP) platform generates adequate hot spots, and thus produces high-density electromagnetic coupling, eventually enabling 240-fold fluorescence enhancement of probed dyes in the near-infrared region. For clinical detection of human samples, TA-GNP provides super-high sensitivity and low detection limits for both hepatitis B surface antigen and SARS-CoV-2 binding antibody, coupled with a much-improved detection dynamic range up to six orders of magnitude. With fast detection, high sensitivity, and low detection limit, TA-GNP could not only substantially improve the outcomes of IFMA-based precision medicine but also find applications in fields of proteomic research and clinical pathology. Electronic Supplementary Material: Supplementary material (UV-Vis absorption and transmission spectra of GNPs, SEM, microscopy and digital images of PEF platforms, and fluorescence images of IFMA on PEF platforms) is available in the online version of this article at 10.1007/s12274-022-5035-6.
ABSTRACT
Introduction: Hepatitis B virus (HBV) and its satellite virus hepatitis D (HDV) are common worldwide hepatotrophic infections responsible for cirrhosis and hepatocellular carcinoma. EASL practice guidelines recommend HDV screening in all Hep B patients. Novel therapies for Hep D are promising. Aim: To determine screening rates for HDV in HBV patients referred to our Laboratory of Hub Hospital Pordenone (Friuli Venezia Giulia). Methods: We retrospectively considered HBsAg positive results from 01.01.2018 to 31.12.2021. Using an extended database to 30.11.2022, we considered, among those were HBsAg positive, anti-HDV results and if we detected positivity for anti-HDV, we checked if HDV-RNA was performed. Results: 931 patients (55% non-Italian native) positive for hepatitis B surface antigen were studied with a majority male patients (65%). Of 931, 470 (50%) Hep B patients were screened for Hep D and 13 (1.4%) (9 non-Italian native) were positive for anti-HDV. Of 13, 6 were positive for serum HDV-RNA;3 subjects were negative for HDV-RNA while 4 patients did not perform HDV-RNA. 10 Hep-B patients (1%) negative for anti-HDV at first time were re-tested for anti-HDV more than once. Comparing 2018-2019 vs 2020-2021, screening rate for Hep D decreased from 56% to 40%. Conclusions: Despite current HDV guidelines, in our Hospital HDV screening is suboptimal and it is actually declining. In fact COVID-19 has caused the slowing down of hepatitis testing program. Therefore we suggest: 1) anti-HDV simplified and automated reflex testing algorithms in Hep B patients for an early diagnosis and linkage to care of HDV infection;2) enhancement of molecular biology for HDV-RNA assay in our Italian Labs;3) repeating more than once anti-HDV especially in high-risk HBV patients. Furthermore, we need to be careful for Hep B vaccine to reduce Hep D screening and disease burden.
ABSTRACT
Introducao: Todos os servicos de saude foram impactados durante a pandemia de COVID-19, os servicos de hemoterapia, que dependem de doadores voluntarios, sofreram com a necessidade de isolamento da populacao e pelo medo do contagio ao vir doar, tambem por doadores infectados e maior numero de transfusoes em pacientes com complicacoes da COVID-19. As outras patologias com necessidade de transfusao ainda existiam e os bancos de sangue tiveram que se reorganizar para buscar ativamente os doadores e atender as medidas necessarias para evitar o contagio, como nao causar aglomeracoes, distanciamento entre as cadeiras do doador e uso de mascara e alcool gel. Objetivos: Avaliar o perfil do doador de sangue do servico de hemoterapia do Hospital Marcio Cunha durante o periodo critico da pandemia de COVID-19. Materiais e Metodos: estudo descritivo, retrospectivo e quantitativo, realizado no servico de hemoterapia atraves de avaliacao do relatorio de producao Hemoterapica - Hemoprod, dos meses de maio 2020 a julho 2021, periodo com elevado numero de obitos por COVID-19 no Brasil. Resultados e Discussao: Nos meses de maio/20 a julho/21 foram entrevistados 12.154 candidatos, sendo 9.449 aptos para doacao de sangue total, media de 629 doadores/mes. A maior parte das doacoes foi espontanea (55,6%), seguida de reposicao e apenas uma doacao autologa no periodo. Em relacao ao tipo de doador;69,7% doaram pela primeira vez;29,5% de forma esporadica e apenas 0,7% de repeticao. A maioria dos doadores foi do genero masculino (58,2%) com idade acima de 29 anos (67,7%). A principal causa da inaptidao na triagem foi descrito como outras (20%), sendo mais comum o uso de medicamentos que impedem a doacao e procedimentos endoscopicos nos ultimos seis meses;3,65% apresentavam hematocrito abaixo do necessario;2,8% hipotensao e 1,04% comportamento de risco para doenca sexualmente transmissivel. No que se refere a triagem sorologica, 221 doadores apresentaram sorologia positiva (2,3%) sendo 47% anti-HBc total reagente, 45.8% sifilis;2,7% anti-HCV;1,8% HBsAg e HTLV e 0,9% HIV. Quanto ao perfil imunohematologico 41,8% foram do grupo O positivo e 28,7% A positivo, sendo os mais frequentes e 9,9% foram O negativo. No periodo foram produzidos 9.323 concentrados de hemacias e transfundidos 6.826 e produzidos 8.948 concentrados de plaquetas e transfundidos 3.983. Conclusao: Nao ha substituto para sangue humano, por isso os servicos de hemoterapia dependem dos doadores voluntarios para manter o estoque de hemocomponentes. No periodo da pandemia houve menor numero de doacoes e maior necessidade de transfusoes em decorrencias das complicacoes da COVID-19. O banco de sangue do Hospital Marcio Cunha atendeu as medidas sanitarias para evitar o contagio e utilizou de estrategias de captacao de doares para tentar diminuir o impacto para o setor assistencial, no periodo analisado o numero de doacoes foi suficiente para atender a demanda transfusional, fato tambem relacionado a reducao de cirurgias eletivas.

ABSTRACT
Rationale: The impact of COVID-19 in patients with autoimmune liver disease treated with immunosuppressive therapy has not been described so far. This case report describes the clinical course of a patient with autoimmune hepatitis (AIH) who developed COVID-19 and the features of cytokine syndrome leading to its deterioration in our intensive care unit. Patient's Concern: A 28-year-old male presented with generalized anasarca for two weeks and chronic liver disease for 8 months. Diagnosis: AIH and Covid-19 with features of cytokine storm syndrome. Interventions: Intravenous furosemide, mannitol, syrup lactulose, steroids (prednisolone 40 mg), azathioprine 1 mg/kg body weight, rifaximin, vitamin K, and blood products. Outcomes: The patient had hepatic encephalopathy and AIH and died on the 10th day after admission despite ventilatory support, sustained low-efficiency hemodialysis, and resuscition. Lessons: The dramatic release of cytokines and the inflammatory-immune responses not only alter the pathophysiology but also affects the onset and severity of disease progression in patients with AIH.
ABSTRACT
Introduction: Different classes of disease-causing viruses are widely distributed universally. Plant-based medicines are anticipated to be effective cures for viral diseases including the COVID-19, instigated by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). This study displays the phylogenetic perspective of Artemisia and proposes some candidate taxa against different viral diseases, including SARS-CoV-2. Methods: Data of Artemisia with antiviral activity were obtained from different published sources and electronic searches. A phylogenetic analysis of the nrDNA ITS sequences of reported antiviral Artemisia species, along with the reference species retrieved from the NCBI GenBank database, was performed using the maximum likelihood (ML) approach. Results: In total, 23 Artemisia species have been documented so far with antiviral activity for 17 different types of viral diseases. 17 out of 23 antiviral Artemisia species were included in the ITS phylogeny, which presented the distribution of these antiviral Artemisia species in clades corresponding to different subgenera of the genus Artemisia. In the resultant ML tree, 10 antiviral Artemisia species appeared within the subgenus Artemisia clade, 2 species appeared within the subgenus Absinthium clade, 3 species appeared within the subgenus Dracunculus clade, and 2 species appeared within the subgenus Seriphidium clade. Discussion: Artemisia species from different subgenera with antiviral activity are prevalent in the genus, with most antiviral species belonging to the subgenus Artemisia. A detailed analysis of taxa from all subgenera, particularly the subgenus Artemisia, is therefore proposed in order to discover compounds with potential anti-SARS-CoV-2 activity.
ABSTRACT
AimsIntroductionCampylobacter infection is not uncommon in children, and extraintestinal manifestations following Campylobacter is a recognized entity, although hepatitis is rare. We present a case of anicteric hepatitis associated with Campylobacter infection in a 13-year-old boyMethodsCase StudyA previously healthy 13-year-old boy was admitted to the paediatric department with a 4-day history of fever and crampy abdominal pain which was localized to the right upper quadrant. He reported loss of appetite and nausea.He was not encephalopathic. His clinical examination was unremarkable, except for diffuse tenderness on deep palpation of the abdomen, especially of the right upper quadrant.His stools were normal initially but 48 hours after admission he developed severe diarrhoea.ResultsHe had elevated alanine transaminase (ALT) level (181 IU/L) on admission. The full blood count showed elevated white cell count with neutrophil leukocytosis, and C-reactive protein level was high (196mg/L). His prothrombin time (PT) and activated partial thromboplastin time (APTT) were within normal limits. The faecal molecular assay detected presence of Campylobacter by polymerase chain reaction (PCR). It did not identify any other organism.The viral hepatitis (Hepatitis A IgM, Hepatitis B surface antigen, Hepatitis C IgM, Hepatitis E IgM, and IgG) panel, Epstein-Barr virus (IgG for nuclear antigen, IgM, and IgG for viral capsid antigen), Cytomegalovirus (IgM and IgG) and Parvovirus B19 (IgM and IgG) screening were negative. Pandemic corona virus was not detected on PCR testing. The auto-antibody panel for autoimmune hepatitis (Anti-nuclear antibody, Anti-smooth muscle antibody, Anti-mitochondrial antibody, Liver kidney microsomal antibody) were normal. The ceruloplasmin level and Alpha-1 anti-trypsin levels were not low. The ultrasound scan of the abdomen revealed normal hepatic architecture, making a chronic liver disease less likely. An alternative explanation for high transaminases were not found.He improved clinically within a week and his liver functions continued to improve.ConclusionDiscussionCampylobacter infection has been associated with extra-intestinal manifestations like Guillain-Barre Syndrome, pancreatitis, erythema nodosum, haemolytic uremic syndrome, thrombotic thrombocytopenic purpura, haemolytic anaemia, glomerular nephritis, and reactive arthritis. Hepatitis is a rare complication of Campylobacterinfection and is rarely reported in medical literature.
ABSTRACT
Background: Opportunistic and chronic infections can arise in the context of treatment used for Autoimmune Rheumatic Diseases (ARDs). Although it is recognized that screening procedures and prophylactic measures must be followed, clinical practice is largely heterogeneous, with relevant recommendations not currently developed or disparately located across the literature. Objectives: To conduct a systematic literature review (SLR) focusing on the screening and prophylaxis of opportunistic and chronic infections in ARDs. This is preparatory work done by members of the respective EULAR task force (TF). Methods: Following the EULAR standardised operating procedures, we conducted an SLR with the following 5 search domains;1) Infection: infectious agents identifed by a scoping review and expert opinion (TF members), 2) Rheumatic Diseases: all ARDs, 3) Immunosuppression: all immunosuppressives/immunomodulators used in rheumatology, 4) Screening: general and specifc (e.g mantoux test) terms, 5) Prophylaxis: general and specifc (e.g trimethop-rim) terms. Articles were retrieved having the terms from domains 1 AND 2 AND 3, plus terms from domains 4 OR 5. Databases searched: Pubmed, Embase, Cochrane. Exclusion criteria: post-operative infections, pediatric ARDs, not ARDs (e.g septic arthritis), not concerning screening or prophylaxis, Covid-19 studies, articles concerning vaccinations and non-Εnglish literature. Quality of studies included was assessed as follows: Newcastle Ottawa scale for non-randomized controlled trials (RCTs), RoB-Cochrane tool for RCTs, AMSTAR2 for SLRs. Results: 5641 studies were initially retrieved (Figure 1). After title and screening and removal of duplicates, 568 full-text articles were assessed for eligibility. Finally, 293 articles were included in the SLR. Most studies were of medium quality. Reasons for exclusion are shown in Figure 1. Results categorized as per type of microbe, are as follows: For Tuberculosis;evidence suggests that tuberculin skin test (TST) is affected by treatment with glucocorticoids and conventional synthetic DMARDs (csDMARDs) and its performance is inferior to interferon gamma release assay (IGRA). Agreement between TST and IGRA is moderate to low. Conversion of TST/IGRA occurs in about 10-15% of patients treated with biologic DMARDs (bDMARDs). Various prophylactic schemes have been used for latent TB, including isoniazide for 9 months, rifampicin for 4 months, isoniazide/rifampicin for 3-4 months. For hepatitis B (HBV): there is evidence that risk of reactivation is increased in patients positive for hepatitis B surface antigen. These patients should be referred for HBV treatment. Patients who are positive for anti-HBcore antibodies, are at low risk for reactivation when treated with glucocorticoids, cDMARDs and bDMARDs but should be monitored periodically with liver function tests and HBV-viral load. Patients treated with rituximab display higher risk for HBV reactivation especially when anti-HBs titers are low. Risk for reactivation in hepatitis C RNA positive patients, treated with bDMARDs is low. However, all patients should be referred for antiviral treatment and monitored periodically. For pneumocystis jirovecii: prophylaxis with trimeth-oprim/sulfamethoxazole (alternatively with atovaquone or pentamidine) should be considered in patients treated with prednisolone: 15-30mg/day for more than 4 weeks. Few data exist for screening and prophylaxis from viruses like E B V, CMV and Varicella Zoster Virus. Expert opinion supports the screening of rare bugs like histoplasma and trypanosoma in patients considered to be at high risk (e.g living in endemic areas). Conclusion: The risk of chronic and opportunistic infections should be considered in all patients prior to treatment with immunosuppressives/immunomod-ulators. Different screening and prophylaxis approaches are described in the literature, partly determined by individual patient and disease characteristics. Collaboration between different disciplines is important.
ABSTRACT
Introduction As part of the national Hepatitis C (HCV) elimination strategy, NHS England aims to eliminate HCV by 2025. As part of this programme, identifying undiagnosed cases through HCV testing is critical. Unfortunately, the global COVID 19 pandemic led to a reduction in HCV testing in England, potentially slowing progress towards elimination. To mitigate the impact of this, innovative ways of increasing HCV testing are required. Individuals detained in police custody have higher rates of injecting drug use than the general population and may therefore be at risk of HCV transmission. Police custody suites may therefore provide an opportunity to offer HCV testing to 'at risk' individuals. In collaboration with local police custody healthcare staff, we developed a pilot of HCV testing for individuals in police custody. Here we describe the outcomes of this pilot Methods Since 01/07/2021, all individuals presenting to Northumbria police custody suites who were reviewed by a healthcare professional were offered Dried Blood Spot test (DBS) for HCV Antibody/RNA, HIV and HBsAg. Individuals were excluded if they were <16 years of age or alleged perpetrators of sexual violence. The Newcastle HCV team were responsible for informing people of their results and establishing those with a positive HCV result on a treatment pathway. Results Of the 3116 people in police custody identified as eligible to be offered BBV testing (See figure 1), 193 accepted (6%). A total of 19 were HCV Ab positive (10% of total individuals tested) and of these 12 were HCV RNA detected (63.0% of HCV Ab positive and 6% of total individuals tested). No cases of HIV or hepatitis B were identified. 137 (71.0%) individuals were negative for all BBV's. Unfortunately, 37 (19%) samples could not be processed by the lab due to insufficient samples (19.0%). This was identified as a training issue and addressed by senior custody suite staff. of the 12 cases of active HCV identified, 5 have commenced HCV antiviral treatment, 6 are awaiting treatment and 1 person is awaiting retesting as the result was 'weak positive'. of the 7 individuals who were HCV Antibody positive but RNA negative, 3 had self-cleared, 3 were known to have received antiviral treatment and achieved a sustained virological response and 1 patient was currently on treatment. Conclusions The pilot demonstrated that HCV screening can successfully be implemented into the police custody suites, leading to a diagnosis of active HCV in 6%. Wider implementation of this strategy could help progress towards HCV elimination.

CAD risk factors: Hypertension, Diabetes Mellitus, Dyslipidaemia, Positive family history of CAD. Admitted with Acute Anterior MI & got Tenecteplase. Relevant Test Results Prior to Catheterization: Troponin-I: >50000 ng/L, ECG: ST Elevation in V1-V6, Echo: Anterior wall is hypokinetic with Mild LV systolic dysfunction (EF- 45%). Hb-14.2 gm/dl, Creatinine: 1.12 mg/dl, Na- 135, K- 4.0, Cl- 100 m mol/L, Plasma BNP: 235 pg/ml, COVID-19 RT-PCR- Negative, S. Bilirubin- 0.3 mg/dl, ALT- 45 IU/L, AST- 107 IU/L, Anti-HCV- Negative, Anti-HIV- Negative, HbsAg- Negative, Relevant Catheterization Findings: LMCA: Normal. LAD: Got 90-99% narrowing in its proximal segment followed by 90-99% diffuse disease. DG1 is small and diseased. DG2 has got sub-total occlusion at its origin. LCX: Good size artery with mild ostial narrowing & 50% narrowing in its mid segment. Principal OM has got 50% narrowing in its ostium. RCA: Dominant artery has got 60% narrowing in its proximal segment. PDA is a good size artery & got mild irregular narrowing in its proximal segment. Recommendation: PCI to LAD [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: LCA was engaged with guiding catheter EBU -3.5 (6F). Sion Blue wire crossed the lesion of LAD, another wire crossed the lesion of Diagonal branch and pre-dilatation was done with 2.0 x 15 mm balloon at 08-10 ATM. Proximal lesion was stented with a 2.75 mm x 18 mm stent (Xience Alpine) at 12-14 ATM. After withdrawing the wire following angiogram showed proximal LAD was well dilated but mid LAD having a long dissection which interrupted the distal flow. So, decided to put stent in mid LAD. Again, repeated ballooning was done in mid LAD to prepare the lesion and a 2.25 mm x 28 mm stent (Xience Xpedition) was taken for mid LAD but stent didn't cross the mid LAD lesion. During stent withdrawal, it was struck in the previous Proximal stent and proximal calcified segment. When trying to pull it back, the delivery system shaft was tear off. Tried to get the shaft by coronary snare but failed to get it back. Finally, he was recommended to retrieve the torn delivery system & stent surgically. [Formula presented] [Formula presented] [Formula presented] Conclusions: • Stent with torn delivery system entrapment might not be rare. • In this situation, emergency decision to tackle the situation and Bail out decision to send the patient for surgical retrieval of the delivery system & stent saved the life of the patient. Take Home Message: • No case is simple in intervention. • Preparedness to tackle any untoward consequence is the key to success and save lives.
