Diagnostic and prognostic role of elafin in skin acute graft versus host disease: a systematic review

Review

Author: Abu Serhan, Hashem ; Bhandari, Pragya ; Barboza, Joshuan J. ; Neupane, Raksha ; Yadav, Rukesh ; Sah, Ranjit ; Paudel, Sunil ; Sah, Sanjit ; Shah, Sangam ; Bhattarai, Abhinav ; Dhakal, Garima

BACKGROUND AND OBJECTIVE:

Graft versus host disease (GVHD) is the common complication seen after allogeneic hematopoietic stem cell transplantation (HSCT) and a pleomorphic syndrome that resembles autoimmune and other immunologic disorders, leading to profound immune dysregulation and organ dysfunction. The most common targets of GVHD are skin, gastrointestinal tract and liver. GVHD is classified as acute graft versus host disease (aGvHD) if it occurs within the first 100 days after HSCT and chronic graft versus host disease(cGVHD) if it occurs after day 100. The skin is most frequently and earliest affected by aGvHD, followed by the gastrointestinal tract and liver. An ideal biomarker would predict the onset and severity of clinical acute GVHD and help to direct management, and this is an area of active research regarding the use of biomarkers for diagnosis and prognosis of acute GVHD. Recently, elafin has been identified as a potential plasma biomarker for aGVHD.

METHOD:

We searched the databases PubMed, Cochrane library, and medRxiv for all studies investigating the Diagnostic or prognostic role of elafin in GVHD. We set the search strategy incorporating the search terms, 'elafin', 'graft versus host', and 'GVHD', and operated using the Boolean operators 'AND', and 'OR'. Thus, retrieved articles were then exported on an Excel® sheet, and duplicates were removed. The systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. After selecting the study based on inclusion criteria, data on study characteristics and biomarker description was extracted on a pre-determined data extraction table on the Microsoft Excel version. The quality assessment of the included studies was determined using the QUIPS tool.

RESULT:

The search revealed 547 studies and 6 studies that met the eligibility criteria of this review have been included. The major finding of our study is the significant elevation of elafin in skin aGVHD.

CONCLUSION:

Elafin is a significant biomarker for diagnosis and prognosis of skin aGVHD and should be assessed within 2 weeks of the onset of the disease.

Use of Rgg quorum-sensing machinery to create an innovative recombinant protein expression system in Streptococcus thermophilus

Article

Author: Balvay, Aurélie ; Langella, Philippe ; Mézange, Christine ; Bermúdez-Humarán, Luis G. ; Monnet, Véronique ; Juillard, Vincent ; Maillot, Nathanael Jean ; Honvo-Houeto, Edith ; Gardan, Rozenn ; Rabot, Sylvie

Streptococcus thermophilus holds promise as a chassis for producing and secreting heterologous proteins. Used for thousands of years to ferment milk, this species has generally recognized as safe (GRAS) status in the USA and qualified presumption of safety (QPS) status in Europe. In addition, it can be easily genetically modified thanks to its natural competence, and it secretes very few endogenous proteins, which means less downstream processing is needed to purify target proteins, reducing costs. Extracellular degradation of heterologous proteins can be eliminated by introducing mutations that inactivate the genes encoding the bacterium’s three major surface proteases. Here, we constructed an inducible expression system that utilizes a peptide pheromone (SHP1358) and a transcriptional regulator (Rgg1358) involved in quorum-sensing regulation. We explored the functionality of a complete version of the system, in which the inducer is produced by the bacterium itself, by synthesizing a luciferase reporter protein. This complete version was assessed with bacteria grown in a chemically defined medium but also in vivo, in the faeces of germ-free mice. We also tested an incomplete version, in which the inducer had to be added to the culture medium, by synthesizing luciferase and a secreted form of elafin, a human protein with therapeutic properties. Our results show that, in our system, protein production can be modulated by employing different concentrations of the SHP1358 inducer or other SHPs with closed amino acid sequences. We also constructed a genetic background in which all system leakiness was eliminated. In conclusion, with this new inducible expression system, we have added to the set of tools currently used to produce secreted proteins in S. thermophilus, whose myriad applications include the delivery of therapeutic peptides or proteins.

Serum Elafin as a Potential Marker of Disease Activity in Behçet's Disease

Article

Author: Kose, Afet Akdag ; Kutlay, Armagan

Background::

Elafin is a serine protease inhibitor with anti-inflammatory properties. It is expressed in various epithelial tissues with increased production under inflammatory conditions. Increased tissue elafin expression in Behçet's disease (BD) lesions has previously been demonstrated.

Aims and Objectives::

We hypothesised that serum elafin might be increased in patients with BD and aimed to assess the relationship of serum elafin with disease activity and organ involvement in BD.

Materials and Methods::

Fifty-four BD patients (29 active, 25 inactive) and 30 healthy controls were included in this single-centre case-control study. Serum elafin was measured using ELISA. Complete blood count, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) tests were also performed.

Results::

Serum elafin levels were significantly higher in patients with BD (1.58 ± 0.47 ng/ml, range: 0.67–2.96) compared to controls (1.10 ± 0.28 ng/ml, range: 0.65–1.49) (P < 0.001). Patients with active BD had higher elafin levels than patients with inactive BD (P = 0.008). Active arthritis was associated with an increase in elafin (P = 0.012), while the presence of mucocutaneous symptoms was not. Serum elafin correlated significantly with ESR (P = 0.001). The ideal cut-off value for the diagnosis of BD was determined as 1.24 ng/ml with a sensitivity and specificity of 72.2% and 70.0%, respectively.

Conclusion::

Serum elafin is significantly increased in patients with BD. It may serve as a marker of disease activity, especially articular involvement.

tiakis Biotech AG Reports Clinical Phase Ib/II Trial Results of Tiprelestat for the Treatment of Hospitalized COVID-19 Patients

Tiprelestat was safe and well tolerated, with initial signs of clinical efficacy KIEL, Germany I December 9, 2024 I tiakis Biotech AG , a clinical-stage biopharmaceutical company developing novel therapeutics for life-threatening pulmonary and cardiovascular diseases, today announced the results of its randomized, double-blind, placebo-controlled clinical Phase Ib/II COMCOVID trial evaluating Tiprelestat for the treatment of patients hospitalized due to COVID-19. In 2021, tiakis Biotech received support from the German Federal Ministry of Education and Research (“BMBF”) to initiate the COMCOVID trial. Tiprelestat (human recombinant Elafin) is an anti-inflammatory human protein and a reversible inhibitor of human neutrophil elastase and proteinase 3 as well as an inhibitor of the formation of neutrophil exosomes and neutrophil extracellular traps. The compound is in development as a potential therapeutic in diseases characterized by an adverse overreaction of innate immune responses, e.g., pulmonary arterial hypertension (PAH) or COVID-19. During the study period, tiakis had to adapt to changes in the COVID-19 pandemic, which led to a significant decrease in the rate of hospitalizations due to this disease. 17 patients could be recruited and treated (9 Tiprelestat, 8 placebo) until the end of the trial period. Even though the power of the small sample size of this study does not allow for a reliable efficacy assessment, it was decided to report all efficacy results. From an exploratory perspective, it is interesting to note that the number of days (mean ± SD) with any oxygen support (i.e. COVID-19 WHO-CPS ≥5 score points) was lower in the Tiprelestat group (2.4 ± 3.6 days) compared to placebo (4.0 ± 6.2 days). In addition, the number of days with relevant renal issues after day 1 was zero in the Tiprelestat group (0 ± 0) compared to the placebo group (1.5 ± 4.2). Consistent with previous clinical trials, the results regarding adverse events, clinical laboratory parameters and vital signs demonstrate that Tiprelestat was safe and well tolerated when administered via infusion in a multiple dose regimen over 7 days. In addition, results of pharmacokinetic evaluation show that Tiprelestat does not accumulate in blood plasma. “Although the trial did not reach the targeted patient number and we cannot draw a reliable conclusion on efficacy, the data reinforce our confidence in the safety profile of Tiprelestat, indicating that it can be administered repeatedly without significant adverse effects in this patient population aged up to 89 years and suffering from a severe inflammatory lung disease,” said Dr. Michael Dreher, Professor of Medicine / Pneumology and Head of the Department of Pneumology and Intensive Care Medicine at the University Hospital Aachen, Germany, and lead medical investigator of the COMCOVID trial. “The solid safety and supportive data in such a diverse and vulnerable patient population will strengthen the development of Tiprelestat in other pulmonary diseases. I would like to thank all our colleagues and partners for their fantastic work under such challenging and unprecedented pandemic conditions,” added Martin Voss, CEO of tiakis Biotech AG. The summary of the clinical study report is publicly available in the German Registry for Clinical Trials ( https://drks.de/search/en/trial/DRKS00031463 ).
