1 · What the graph read from it

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.

2 · The registry

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

Rabies is a fatal viral encephalitis characterized by a clinically acute and progressive course. With rare exceptions, there is a discrepancy between clinical outcome and frank histological alterations in rabies. Investigators have postulated that rabies virus may modify neurotransmission through occupancy of cellular receptors or alteration of ion channels. We took advantage of these observations to improvise a successful therapy for rabies. The Milwaukee protocol ( www.mcw.edu/rabies ) was further modified to treat two German patients. We measured pterins and monoamine neurotransmitter metabolites in the CSF of patients with rabies by HPLC with electrochemical or fluorescent detection. We report loss of tetrahydrobiopterin (BH(4)) and associated pathological decrease of dopaminergic and serotoninergic neurotransmission in three successive patients with rabies. CSF levels of BH(4) and neurotransmitter metabolites increased in two patients who were supplemented. Our findings support the long-standing speculation of modified neurotransmission in the pathogenesis of rabies, but by another mechanism. Brain turnover of dopamine and serotonin is reduced following rabies-acquired BH(4) deficiency. Neuronal nitric oxide synthase is BH(4)-dependent and may also be involved, possibly causing cerebrovascular insufficiency in one patient. This work must be carefully replicated in animal models and future patients. We are cautiously optimistic at the prospect of readily available, metabolically specific, enteral therapy for rabies.
