Belgian, US scientists look to llamas in search for Covid-19 treatment

A llama called Winter could prove useful in the hunt for a treatment for Covid-19, according to US and Belgian scientists who have identified a tiny particle that appears to block the new coronavirus.

The scientists, from Belgium’s VIB-UGent center for medical biotechnology and the University of Texas at Austin, published research on Tuesday in the journal Cell, with the llama in Belgium central to their studies.

The group began four years ago looking into antibodies that might counter the Sars virus, which spread in 2003, and the Mers virus that flared up in 2012.

“The work was a side project in 2016. We thought maybe this was interesting,” said Xavier Saelens, joint leader of the Belgian part of the collaboration. “Then the new virus came and it became potentially more crucial, more important.”

Winter, the llama, was given safe versions of the Sars and Mers viruses and samples of its blood were later taken.

Llamas and other members of camel family are distinct in creating standard antibodies and smaller antibodies, with which scientists can more easily work.

The Belgian part of the research team, also led by Bert Schepens, identified fragments of the smaller antibodies, known as nanobodies, to see which bound most strongly to the virus.

Saelens describes the new coronavirus as the cousin of the Sars virus. Both have a corona, or crown, shape with protein spikes, onto which an antibody can latch.

The team intend to begin tests on animals, with a view to allowing trials with humans to begin by the end of the year. Saelens said negotiations were under way with pharmaceutical companies.

The research is not the first into nanobodies derived from camels or llamas. French group Sanofi paid 3.9 billion euros ($4.23 billion) in 2018 to buy Ghent-based nanobody specialist company Ablynx.

Sulfamoyl Heteroarylcarboxylic Acids as Promising Metallo-{beta}-Lactamase Inhibitors for Controlling Bacterial Carbapenem Resistance

ABSTRACT

Production of metallo-β-lactamases (MBLs), which hydrolyze carbapenems, is a cause of carbapenem resistance in Enterobacteriaceae. Development of effective inhibitors for MBLs is one approach to restore carbapenem efficacy in carbapenem-resistant Enterobacteriaceae (CRE). We report here that sulfamoyl heteroarylcarboxylic acids (SHCs) can competitively inhibit the globally spreading and clinically relevant MBLs (i.e., IMP-, NDM-, and VIM-type MBLs) at nanomolar to micromolar orders of magnitude. Addition of SHCs restored meropenem efficacy against 17/19 IMP-type and 7/14 NDM-type MBL-producing Enterobacteriaceae to satisfactory clinical levels. SHCs were also effective against IMP-type MBL-producing Acinetobacter spp. and engineered Escherichia coli strains overproducing individual minor MBLs (i.e., TMB-2, SPM-1, DIM-1, SIM-1, and KHM-1). However, SHCs were less effective against MBL-producing Pseudomonas aeruginosa. Combination therapy with meropenem and SHCs successfully cured mice infected with IMP-1-producing E. coli and dually NDM-1/VIM-1-producing Klebsiella pneumoniae clinical isolates. X-ray crystallographic analyses revealed the inhibition mode of SHCs against MBLs; the sulfamoyl group of SHCs coordinated to two zinc ions, and the carboxylate group coordinated to one zinc ion and bound to positively charged amino acids Lys224/Arg228 conserved in MBLs. Preclinical testing revealed that the SHCs showed low toxicity in cell lines and mice and high stability in human liver microsomes. Our results indicate that SHCs are promising lead compounds for inhibitors of MBLs to combat MBL-producing CRE.

IMPORTANCE Carbapenem antibiotics are the last resort for control of severe infectious diseases, bloodstream infections, and pneumonia caused by Gram-negative bacteria, including Enterobacteriaceae. However, carbapenem-resistant Enterobacteriaceae (CRE) strains have spread globally and are a critical concern in clinical settings because CRE infections are recognized as a leading cause of increased mortality among hospitalized patients. Most CRE produce certain kinds of serine carbapenemases (e.g., KPC- and GES-type β-lactamases) or metallo-β-lactamases (MBLs), which can hydrolyze carbapenems. Although effective MBL inhibitors are expected to restore carbapenem efficacy against MBL-producing CRE, no MBL inhibitor is currently clinically available. Here, we synthesized 2,5-diethyl-1-methyl-4-sulfamoylpyrrole-3-carboxylic acid (SPC), which is a potent inhibitor of MBLs. SPC is a remarkable lead compound for clinically useful MBL inhibitors and can potentially provide a considerable benefit to patients receiving treatment for lethal infectious diseases caused by MBL-producing CRE.

Burkholderia ubonensis Meropenem Resistance: Insights into Distinct Properties of Class A {beta}-Lactamases in Burkholderia cepacia Complex and Burkholderia pseudomallei Complex Bacteria

ABSTRACT

Burkholderia pseudomallei, the founding member of the B. pseudomallei complex (Bpc), is a biothreat agent and causes melioidosis, a disease whose treatment mainly relies on ceftazidime and meropenem. The concern is that B. pseudomallei could enhance its drug resistance repertoire by the acquisition of DNA from resistant near-neighbor species. Burkholderia ubonensis, a member of the B. cepacia complex (Bcc), is commonly coisolated from environments where B. pseudomallei is present. Unlike B. pseudomallei, in which significant primary carbapenem resistance is rare, it is not uncommon in B. ubonensis, but the underlying mechanisms are unknown. We established that carbapenem resistance in B. ubonensis is due to an inducible class A PenB β-lactamase, as has been shown for other Bcc bacteria. Inducibility is not sufficient for high-level resistance but also requires other determinants, such as a PenB that is more robust than that present in susceptible isolates, as well as other resistance factors. Curiously and diagnostic for the two complexes, both Bpc and Bcc bacteria contain distinct annotated PenA class A β-lactamases. However, the protein from Bcc bacteria is missing its essential active-site serine and, therefore, is not a β-lactamase. Regulated expression of a transcriptional penB'-lacZ (β-galactosidase) fusion in the B. pseudomallei surrogate B. thailandensis confirms that although Bpc bacteria lack an inducible β-lactamase, they contain the components required for responding to aberrant peptidoglycan synthesis resulting from β-lactam challenge. Understanding the diversity of antimicrobial resistance in Burkholderia species is informative about how the challenges arising from potential resistance transfer between them can be met.

IMPORTANCE Burkholderia pseudomallei causes melioidosis, a tropical disease that is highly fatal if not properly treated. Our data show that, in contrast to B. pseudomallei, B. ubonensis β-lactam resistance is fundamentally different because intrinsic resistance is mediated by an inducible class A β-lactamase. This includes resistance to carbapenems. Our work demonstrates that studies with near-neighbor species are informative about the diversity of antimicrobial resistance in Burkholderia and can also provide clues about the potential of resistance transfer between bacteria inhabiting the same environment. Knowledge about potential adverse challenges resulting from the horizontal transfer of resistance genes between members of the two complexes enables the design of effective countermeasures.

Gathering Trauma Narratives: A Qualitative Study on the Impact of Self-Identified Traumas on People Living with HIV (PLWH)

BACKGROUND Trauma—emotional, physical, and psychological—is common and associated with increased risk behaviors, low rates of care engagement and viral suppression, and overall poor health outcomes for people living with HIV (PLWH). This article presents the results of 15 in-depth, semi-structured interviews with PLWH in the Southeastern United States in which participants identified a trauma and described its long-lasting impact on their lives. Participants' trauma narratives described a wide range of traumas, including childhood sexual abuse, the loss of a loved one, and their HIV diagnosis.

METHODS Systematic qualitative analysis was used to delineate beliefs about causes, symptoms, treatments, quality of life, and health implications of trauma.

RESULTS: Fifteen participants completed semi-structured interviews that lasted on average 32 minutes. Participants described a wide spectrum of personal trauma that occurred both prior and subsequent to their HIV diagnosis. The types of trauma identified included physical, sexual, and psychological abuse inflicted by intimate partners, family members, and/or strangers.

LIMITATIONS A chief limitation of this study is selection bias. Additionally, the participant selection and content of the trauma narratives might have been affected by the surrounding context of the parent study centered on HIV, aging, and psychosocial stress. It is also difficult to interpret the distinction between discrete trauma experiences and the diagnosis of HIV, leading to potential information bias.

CONCLUSION This study highlights the importance of social support in coping with trauma and the effect of trauma on health-related behaviors. It also illustrates the need for additional research on the topic of trauma and trauma-informed care for PLWH. Understanding how different types of trauma affect individuals' lives is necessary to inform recommendations to provide better care for PLWH.
