Greek ἀφῆκεν ('he permitted/let') and Syriac ܫܒܩ (root sh-b-q, 'to leave/allow') agree in sense, while the Vulgate admisit ('he admitted/let in') is a slightly more specific lexical choice, all conveying permission to follow.
EN He allowed no one to follow him, except Peter, James, and John the brother of James.
ES Y no permitió que alguno viniese tras él sino Pedro, y Jacobo, y Juan hermano de Jacobo.

Greek uses the masculine indefinite pronoun οὐδένα ('no one') already negated; Syriac employs ܠܐܢܫ ('any man', literally 'to a man', with object marker l-) whose negative force is supplied by the preceding ܘܠܐ; Latin quemquam likewise relies on the prior non. The constructions are equivalent.
Greek has the prepositional phrase μετ᾽ αὐτοῦ followed by the infinitive συνακολουθῆσαι ('to follow with'); Syriac inverts to ܕܢܐܙܠ ܥܡܗ ('that he should go with him'), rendering the compound verb with a finite-style subordinate clause plus separate preposition; Latin se sequi places the reflexive before the infinitive. All express accompanying Jesus.
Where Greek and Latin give simply Πέτρον / Petrum, the Peshitta expands to ܠܫܡܥܘܢ ܟܐܦܐ ('Simon Kepha'), preserving the apostle's Semitic name Simon together with the Aramaic epithet Kepha that underlies Greek Πέτρος; this is a characteristic Syriac retention rather than a textual variant.
