Per-guideline notes¶
- NeuPSIG 2015: 229 trials; first-line TCAs, SNRIs, gabapentin and pregabalin; modest NNTs and publication-bias concern (PMID 25575710).
- EAN–EFIC–NeuPSIG 2023: lesion-based history/examination with targeted neurophysiology, imaging, biopsy and QST (PMID 37253688).
- French guidance: places pregabalin and combinations later than NeuPSIG and integrates TENS, psychotherapy, rTMS and SCS (PMID 32276788).
- AAN diabetic guideline: choose among effective classes, switch class after failure and avoid opioids (PMID 34965987).
- ASCO CIPN: no established preventive drug; duloxetine for painful established CIPN; consider chemotherapy modification for functional toxicity (PMID 32663120).
- DGN 2019/2020: combines lesion confirmation with small-fiber tests; lists pregabalin, gabapentin, duloxetine and amitriptyline first-line, topical capsaicin/lidocaine second-line or initial options for focal pain, and opioids third-line (PMID 33324922).
- Brazilian central-pain consensus: 44 studies were identified, 20 qualitatively synthesized and 15 meta-analyzed; gabapentin, duloxetine and TCAs were placed first-line, with condition-specific roles for pregabalin after SCI and lamotrigine after stroke, but the panel states that much guidance rests on expert opinion (PMID 33331468).
- Italian pharmacoresistance consensus: defines resistance as failing to reach 50% pain reduction or a ≥2-point Patient Global Impression of Change improvement after all recommended drug classes, each used for at least one month after titration to the highest tolerated dose (PMID 30941628).
- Chinese ion-channel consensus: provides drug-specific practice recommendations for carbamazepine, oxcarbazepine, lidocaine, bulleyaconitine A, pregabalin and gabapentin; its consensus design and country-specific formulary context limit transferability (PMID 33850929).
- PEER 2022: used three reviews covering 285 RCTs and required responder outcomes; unlike neuropathic-pain-specific panels, it treats several chronic-pain conditions together and judges exercise benefit unclear specifically for neuropathic pain while advising that opioid/cannabinoid harms likely outweigh benefits for most covered conditions (PMID 35292455).
- Spanish interventional consensus: 35 experts entered round 1 and 29 round 2; consensus was reached for 20/26 statements, supporting graded escalation while explicitly describing the evidence as sparse and fragmented (PMID 35630044).
- Latin American adaptation: screened 674 neuropathic-pain guideline records, shortlisted 14 and endorsed NeuPSIG 2015 as the best regional fit, supplemented by implementation considerations rather than a new evidence synthesis (PMID 29025132).
- Exercise consensus: 8 systematic reviews and 21 RCTs informed ten etiology-specific statements, but its broad recommendation for exercise contrasts with PEER’s conclusion that benefit is unclear for neuropathic pain (PMID 34901069; PMID 35292455).
- NICE CG173: offers amitriptyline, duloxetine, gabapentin or pregabalin initially for neuropathic pain other than trigeminal neuralgia, requires early and regular review of pain, participation, wellbeing and harms, and advises tapering when switching or withdrawing. The guideline was published in 2013, last substantively updated in 2020, and has received later safety-link amendments ([NICE — “Neuropathic pain in adults: pharmacological management in non-specialist settings”, https://www.nice.org.uk/guidance/cg173, accessed 2026-08-30; PMID 20335333).
- NeuPSIG interventional 2013: found no basis for a strong recommendation; made weak recommendations for epidural injection in herpes zoster, steroid injection for radiculopathy and SCS for failed-back-surgery syndrome or CRPS-I, while recommending against sympathetic blocks for PHN and radiofrequency lesions for radiculopathy (PMID 23748119).
- South African panel: recommends gabapentinoids, low-dose TCAs and SNRIs first-line for peripheral pain, switching or combining after an insufficient 2–4-week response, reserving opioids for later, and prioritizing trials in painful HIV-associated sensory neuropathy (PMID 22554341).
- Polish two-part recommendations: place history and a somatosensory examination at the diagnostic core and acknowledge that scarcity of high-quality syndrome-specific trials weakens treatment recommendations; their inclusion of opioids among first-line options differs materially from NeuPSIG 2015 and more recent AAN/PEER positions (PMID 25168326; PMID 25482254).
- Japanese second edition: uses stepwise pharmacotherapy but includes a Japan-specific rabbit-skin extract for PHN as second-line, places opioids third-line with repeated abuse/addiction assessment, and does not recommend NSAIDs or acetaminophen for lack of efficacy evidence (PMID 29737410).
- CanPainSCI 2021 update: reviewed 46 additional articles, added three screening/diagnosis and eight treatment recommendations, and applied AGREE II and GRADE; it supersedes the 2016 CanPainSCI series for current SCI-specific practice (PMID 35124700).
Disagreements and gaps¶
| Topic | Disagreement/gap |
|---|---|
| Pregabalin | First-line in NeuPSIG; second-line in French guidance |
| Topical lidocaine | Low evidence but favorable safety creates different placement |
| Opioids | Later-line wording differs; long-term evidence remains inadequate |
| Devices | Indications and certainty vary; long-term sham-controlled evidence sparse |
| Phenotyping | Encouraged for research; no validated prescribing algorithm |
| Combination therapy | OPTION-DM supports rescue, but most guidelines predate it |
| Exercise | Chinese rehabilitation consensus recommends appropriately prescribed exercise across etiologies; PEER finds neuropathic-pain benefit unclear |
| Pharmacoresistance | Italian Delphi definition requires failure across all recommended classes; other documents use looser “refractory” language or no operational definition |
| Central pain | Brazilian consensus offers condition-specific sequencing, but explicitly relies partly on expert opinion because trials are sparse and heterogeneous |
| Interventions | Spanish Delphi consensus supports graded escalation for selected syndromes; evidence grading and sham-controlled durability remain insufficient |
| Regional transfer | Latin American, Chinese, Brazilian and German recommendations reflect different availability, reimbursement and panel methods; apparent disagreement may be contextual rather than biological |
| Initial opioids | Polish 2014 recommendations included opioids among first-line drugs; NeuPSIG 2015, NICE, AAN and PEER place them later, restrict them, or judge harms to outweigh benefits |
| Intervention certainty | NeuPSIG 2013 could make only four weak positive recommendations; Spanish 2022 Delphi consensus is more permissive for selected syndromes but does not replace sham-controlled comparative evidence |
| Local products | Japanese guidance includes a country-specific rabbit-skin extract for PHN, illustrating why formulary-based recommendations do not automatically transfer internationally |
