An anti-perfringolysin O monoclonal antibody cross-reactive with streptolysin O protects against streptococcal toxic shock syndrome.
Article in BMC research notes, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveStreptococcus pyogenes (Group A Streptococcus; GAS) causes a variety of infections that include life-threatening, severe invasive GAS infections, such as streptococcal toxic shock syndrome (STSS), with > 30% mortality rate, despite effective antibiotics and treatment options. STSS clinical isolates highly express streptolysin O (SLO), a member of a large family of pore-forming toxins called cholesterol-dependent cytolysins (CDCs). SLO is an important toxic factor for GAS and may be an effective therapeutic target for the treatment of STSS. Our aim was to identify a monoclonal antibody (mAb) that reacts with SLO and has therapeutic potential for STSS treatment.
resultsWe focused on mAbs that had originally been established as neutralizing reagents to perfringolysin O (PFO), another member of the CDC family, as some cross-reactivity with SLO had been reported. Here, we confirmed cross-reactivity of an anti-PFO mAb named HS1 with SLO. In vitro analysis revealed that HS1 mAb sufficiently prevented human neutrophils from being killed by STSS clinical isolates. Furthermore, prophylactic and therapeutic injection of HS1 mAb into C57BL/6 mice significantly improved the survival rate following lethal infection with an STSS clinical isolate. These results highlight the therapeutic potential of HS1 mAb for STSS treatment.
