We investigated the kinetics of CRP, PCT, IL-6 and MR-proADM in a cohort of consecutive febrile patients with cancer in order to test the hypothesis that higher plasma concentrations and the absence of a rapid decrease in peak values would be associated with disease severity. (1) Method: A prospective descriptive and analytical study of patients with cancer and fever (≤18 years of age) at a University Hospital was carried out between January 2018 and December 2019. Information collected: sex, age, diagnosis, date and symptoms at diagnosis and medical history. The episodes were classified into three groups: bacterial infection, non-bacterial infection and systemic inflammatory response syndrome (SIRS). (2) Results: One hundred and thirty-four episodes were included. Bacterial infection criteria were met in 38 episodes. Biomarkers were measured at four different points: baseline, at 12–24 h, at 25–48 h and at 49–72 h. All the biomarkers evaluated decreased after the peak level was reached. IL-6 and MR-proADM showed a trend towards higher levels in the SIRS group although this rise was statistically significant only for IL-6 (p < 0.005). Bacterial infections more frequently presented values of PCT above the cut-off point (>0.5 ng/mL) at 12–24 h. (3) Conclusion: In our experience, IL-6 kinetics is faster than PCT kinetics and both are faster than CRP in patients with fever and cancer who present a good outcome. Patients with a good evolution show a rapid increase and decrease of PCT and particularly of IL-6 levels.

Patients At Risk

Opportunistic bacterial infections are dreaded risks in patients following liver transplantation (LTX), even though patients receive an antibiotic prophylaxis. The timely recognition of such an infection may be delayed, as culture-based diagnostic methods are linked with a relevant gap in performance. We measured plasma concentrations of Delta-like canonical Notch ligand 1 (DLL1) in 93 adult patients at seven consecutive time points after liver transplantation and correlated the results to the occurrence of culture-proven bacterial infection or a complicated clinical course (composite endpoint of two or more complications: graft rejection or failure, acute kidney failure, acute lung injury, or 90-day mortality). Patients exhibited elevated plasma concentrations after liver transplantation over the whole 28 d observation time. Patients with bacterial infection showed increased DLL1 levels compared to patients without infection. Persistent elevated levels of DLL1 on day 7 and afterward following LTX were able to indicate patients at risk for a complicated course. Plasma levels of DLL1 following LTX may be useful to support an earlier detection of bacterial infections in combination with C-reactive protein (CRP) and procalcitonin (PCT), or they may lead to risk stratification of patients as a single marker for post-operative complications.

Conventional diagnostic test have limitations to deferential diagnosis in clinical suspicion ofbacterial infection cases, that in some cases lead to inappropriate antibiotic therapy and increases antibiotic resistance. A new diagnostic insight is procalcitonin (PCT) test to improve diagnosis of bacterial infections and to guide antibiotic therapy. Serum PCT levels are of useful test as a biomarker in patients with bacterial infections for several reasons. Initial rise of PCT levels due to bacterial infection, subsequent sequential PCT levels can be used to assess the effectiveness and duration of antibiotic therapy. Based on clinical researches results, in bacterial infections, promising good results obtained when use of PCT used as differential diagnostic test. But further intervention studies are needed before use of PCT in clinical routine tests. The goal of this review is to study the PCT reliability as infections diagnostic biomarker.

IntroductionResearch into paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) has focused on tertiary level management. This review reports on symptoms and investigations at presentation.MethodsSingle centre retrospective case note analysis of patients fulfilling PIMS-TS diagnostic criteria from March to May 2020 in a London district level university hospital.ResultsSix patients presented in the week prior to their final diagnosis with fever and non-specific symptoms. Raised C-reactive protein (CRP), lymphopenia and hyponatraemia were noted. Kawasaki-like symptoms were under-represented in all patients.InterpretationThe results suggest that a proportion of children with early PIMS-TS present with a non-specific febrile illness and abnormal blood results. Further research is needed to determine the most appropriate identification and follow-up of these children.

AbstractTo investigate the effect of simulated weightlessness on the pharmacokinetics of orally administered moxifloxacin and the antacid Maalox or the antidiarrheal Pepto-Bismol using a tail-suspended (TS) rat model of microgravity. Fasted control and TS, jugular-vein-cannulated, male Sprague-Dawley rats received either a single 5 mg/kg intravenous dose or a single 10 mg/kg oral dose of moxifloxacin alone or with a 0.625 mL/kg oral dose of Maalox or a 1.43 mL/kg oral dose of Pepto-Bismol. Plasma concentrations of moxifloxacin were measured by HPLC. Pharmacokinetic data were analyzed using WinNonlin. Simulated weightlessness had no effect on moxifloxacin disposition after intravenous administration but significantly decreased the extent of moxifloxacin oral absorption. The coadministration of moxifloxacin with Maalox to either control or TS rats caused significant reductions in the rate and extent of moxifloxacin absorption. In contrast, the coadministration of moxifloxacin with Pepto-Bismol to TS rats had no significant effect on either the rate or the extent of moxifloxacin absorption. These interactions showed dose staggering when oral administrations of Pepto-Bismol and moxifloxacin were separated by 60 min in control rats but not in TS rats. Dose staggering was more apparent after the coadministration of Maalox and moxifloxacin in TS rats.

Introduction. Although well protected, brain is not resistant to infection agents. Acute infections of our nervous system appear more often in children and in persons who have medical history data about previous disorders, especially disorders of the nervous system. It is difficult to list possible risk factors which can be responsible for the appearance of infections of CNS and the resulting conditions. It is often difficult or impossible to determine what previous neural damage was (trauma, anoxic damages etc.) from those appearing during infections of CNS. All-inclusive anamnestic research reduces the possibility of approximate judgments. Material and methods. The research was based on the retrospective analysis of medical documentation of 275 patients. All patients were divided into three groups according to the final diagnosis. The first group consisted of 125 patients who were treated for acute virus encephalitis, the second group consisted of 125 patients who were treated for acute bacterial meningoencephalitis and the third group consisted of 25 patients who were treated for cerebritis. Discussion. In our studies sample, the youngest patient was 3 years old and the oldest was 87 years old. The highest number of patients with virus infection of the CNS was in the group under 25 years of age (45.6%). The highest number of patients with bacterial infections of the CNS and cerebritis was in the group of patients over 45 years of age (64%, 37%). Conclusion. Risk factors were more present in bacterial infections of the nervous system and cerebrit thanin virus infection of CNS. In virus infections of the CNS, 28% of patients had some risk factor, most often-chronic ethylism, diabetes mellitus and acquired heart diseases. In bacterial infections of the CNS, 64% of patients had some predisposed factor. The most frequent factor of risk in these patients were chronic otitis (21.6%) and craniotrauma (14.4%). In cerebritis, risk factors were present in 76% of patients and they were: sepsis (20%), chronic otitis (12%) and systemic lupus erythematosus (8%).

ABSTRACTNB-003 and NB-003 gel formulations are oil-in-water nanoemulsions designed for use in bacterial infections.In vitrosusceptibility ofPropionibacterium acnesto NB-003 formulations and comparator drugs was evaluated. Both NB-003 formulations were bactericidal against allP. acnesisolates, including those that were erythromycin, clindamycin, and/or tetracycline resistant. In the absence of sebum, the MIC90s/minimum bactericidal concentrations (MBC90s) for NB-003, NB-003 gel, salicylic acid (SA), and benzoyl peroxide (BPO) were 0.5/2.0, 1.0/2.0, 1,000/2,000, and 50/200 μg/ml, respectively. In the presence of 50% sebum, the MIC90s/MBC90s of NB003 and BPOs increased to 128/1,024 and 400/1,600 μg/ml, respectively. The MIC90s/MBC90s of SA were not significantly impacted by the presence of sebum. A reduction in the MBC90s for NB-003 and BPO was observed when 2% SA or 0.5% BPO was integrated into the formulation, resulting in MIC90s/MBC90s of 128/256 μg/ml for NB003 and 214/428 μg/ml for BPO. The addition of EDTA enhanced thein vitroefficacy of 0.5% NB-003 in the presence or absence of 25% sebum. The addition of 5 mM EDTA to each well of the microtiter plate resulted in a >16- and >256-fold decrease in MIC90and MBC90, yielding a more potent MIC90/MBC90of ≤1/<1 μg/ml. The kinetics of bactericidal activity of NB-003 againstP. acneswere compared to those of a commercially available product of BPO. Electron micrographs ofP. acnestreated with NB-003 showed complete disruption of bacteria. Assessment of spontaneous resistance ofP. acnesrevealed no stably resistant mutant strains.

Important Interaction

Background:Dermatological manifestations are not rare in patients with rheumatic diseases (RD). Multidisciplinary management and direct interaction between these disciplines are essential. According to Dermatology-Rheumatology clinics, most diagnoses evaluated are systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), with dermatitis being the most common manifestation. It is important to be aware that skin problems in RD patients are not always related to the underlying condition(1). Nowadays, there is significant evidence to support the manifold advantages of the joint dermatology-rheumatology clinics, including improved quality of care for patients and multidisciplinary training for new physicians(2). This ongoing trend is intended to highlight the important interaction between specialties that treat overlapping conditions, and it has been incorporated in academic health centers to give a comprehensive approach to patients.Objectives:Our purpose was to describe the collaboration between the Rheumatology and Dermatology services during the evaluation of RD patients.Methods:An observational, retrospective study was performed in the Rheumatology Service of the University Hospital “Dr. Jose Eleuterio Gonzalez” in Monterrey, Mexico, between March 2019 and February 2020. All the patients with a Rheumatology or Dermatology consultation requested were included (hospitalized and outpatients). Demographic (age, gender, baseline diagnosis), the reason for consultation, specialty requested, type of treatment, final diagnoses, and agreement in final diagnosis were registered. Results are shown in descriptive statistics.Results:One hundred and seventy-four patients were included, 142 (81.6%) patients from the outpatient clinic and 32 (18.4%) patients hospitalized. The mean age was 45.1 (SD±15.8) years, 135 (77.6%) were females, 54 (31%) patients were under initial diagnosis evaluation, 30 (17.2%) had RA, 25 (14.4%) patients had SLE, 15 (8.6%) patients had psoriatic arthritis, 12 (6.9%) patients had systemic sclerosis, 6 (3.4%) patients had dermatomyositis. The main reasons for consultation in hospitalized patients were acute lupus (15.6%), subacute lupus (12.5%), purpura (12.5%), cutaneous vasculitis (9.4%), urticarial dermatitis (9.4%), dermatomyositis (6.3%) and others (34.3%). The consultation requested was: 156 (89.7%) to Dermatology and 18 (10.3%) to Rheumatology. The type of treatment prescribed was topic/local in 37 (21.3%) patients, systemic in 25 (14.4%) and both in 92 (52.9%) patients. The final diagnoses were related to the underlying disease in 102 (77%) patients and unrelated in 40 (23%) patients. The agreement between initial clinical suspicion and final diagnoses reached 75.9% between Rheumatology and Dermatology services. Figure 1.Conclusion:The collaboration between Rheumatology and Dermatology services are very important. Most of the patients were under initial evaluation. All the rheumatologists and dermatologists should be aware of the interdependence from both specialties to give the best quality of care to the patients.References:[1]Samycia M, McCourt C, Shojania K, Au S.
