New Guidelines Issued for Managing Chronic Pain in HIV Patients

Table 1
Screening and Initial Assessment

Recommendation Commentary/Details
Standardized screening
  • How much bodily pain have you had during the last week (none, very mild, mild, moderate, severe, very severe)
  • Do you have bodily pain that has lasted for >3 months?
  • A response of moderate pain or more during last week plus bodily pain for >3 months can be considered a positive screen result
If patient screens positive on initial assessment
  • Use biopsychosocial approach that includes:
    • An evaluation of the pain’s —
      • Onset and duration
      • Intensity and character
      • Exacerbating and alleviating factors
      • Past and current treatments
      • Underlying or co-occurring disorders and conditions
      • The effect of pain on psychological function
    • Physical examination
    • Psychosocial evaluation
    • Diagnostic workup
    • Pain assessment tools can include
      • Brief Pain Inventory (BPI)
      • 3-item pain health questionnaire (PEG)
Monitoring patients
  • Periodically assess progress on achieving functional goals
  • Documentation of pain intensity, quality of life, adverse events, and adherent vs aberrant behaviors
  • Conduct assessments at regular intervals and after each change/initiation of therapy after an adequate amount of time 

Table 2
Nonpharmacologic Approaches for PLWH

Modality Features, Rationale
CBT
  • Acceptance of responsibility for change
  • Development of adaptive behaviors (eg. exercise)
  • Addressing maladaptive behaviors (eg, avoidance of exercise due to fear of pain)
Yoga
  • Treatment of chronic neck/back pain, headache, rheumatoid arthritis, general musculoskeletal pain
Physical/occupational therapy
  • For chronic pain
Hypnosis
  • Neuropathic pain
Acupuncture
  • A trial might be considered for chronic pain

CBT=cognitive behavioral therapy

Table 3
Pharmacologic Treatments for Chronic Neuropathic Pain in PLWH

Treatment Recommendations
Antiretroviral therapy
  • Early initiation recommend for preventing/treating HIV-associated distal symmetric polyneuropathy
Gabapentin
  • First-line oral pharmacologic treatment
  • Typical adult regimen titrates to 2400mg/day in 2 divided doses
  • Improves sleep scores, somnolence
  • Patients with inadequate response might receive
    • Trial of SNRIs
    • Trial of TCAs
    • Trial of pregabalin for patients with post-herpetic neuralgia
Medical cannabis
  • May be effective in appropriate patients
  • Relatively high value placed on symptoms reduction, relatively low value placed on legal implication of medical cannabis possession
  • May be more effective for patients with prior cannabis use
  • Balance potential benefits against potential risks of neuropsychiatric adverse effects
  • Balance potential benefit against harmful effects of smoked forms in patients with preexisting severe lung disease
  • Balance risks of addiction in patients with cannabis use disorder
Alpha lipoic acid
  • For peripheral difficult-to-treat neuropathic pain
  • May be helpful for patients with diabetic neuropathy
Lamotrigine
  • Not recommended
  • May cause lamotrigine-related rash
Opioid analgesics
  • Do not use as first-line agents
  • Potential risk of pronociception, cognitive impairment, respiratory depression, endocrine/immunological changes, misuse/addiction
  • Consider time-limited trial for patients who do not respond to first-line therapies and report moderate-to-severe pain
  • Use smallest effective dose
  • Combine short- and long-acting opioids

HIV=human immunodeficiency virus; SNRI-serotonin-norepinephrine reuptake inhibitors; TCS=tricyclic antidepressant

Table 4
Opioid Analgesics for PLWH

Agent Comments/Rationale
Opioids as a class
  • Balance potential benefits with potential risks of adverse events, misuse, diversion, and addiction
  • As second- or third-line treatment, typical adult regimen should start with lowest effective dose and combine short- and long-acting opioids
Tramadol
  • Up to 3 months of use
  • May decrease pain and improve stiffness, function, overall well-being in patients with osteoarthritis
  • Use 37.5mg combined with 325mg of acetaminophen once/day to 400mg in divided doses

Table 5
Safeguarding Against Opioid-Related Harm

Recommendation Comments/Rationale
Routine monitoring
  • Consists of several components
    • Urine drug testing
    • Pill counts 
    • Prescription drug monitoring programs
Opioid patient-provider agreement (PPA)
  • Tool for shared decision-making
  • Consists of 2 components
    • Informed consent
    • Plan of care
  • Consider broad differential diagnosis when patient’s behavior is inconsistent with PPA
Urine drug testing
  • Understand clinical uses/limitations
  • Understand test characteristics
  • Understand differential diagnosis of abnormal results

Table 6
Recommended Methods to Minimize Adverse Opioid-Related Events in PLWH

Recommendation Comments/Details
Safe storage
  • Store safely away from individuals at risk of misuse/overdose
Patient/family education
  • Educate family members about overdose signs
  • Have poison control number readily visible
  • Teach patients/caregivers about use of naloxone to reverse overdose and have naloxone rescue kit available
  • Educate patients/caregivers about adverse effects related to drug-drug interactions
Be knowledgeable about drug-drug interactions
  • Be prepared to identify/manage these interactions
  • Follow patients closely when interactions are likely

Table 7
Pharmacologic Management of Chronic Pain in PLWH Who Are Taking Methadone

Recommendation Comments/Details
Collaboration with opioid treatment program
  • Obtain signed release
  • Maintain ongoing communication with program for assessment/periodic monitoring
Initial screening
  • Electrocardiogram to identify QTc interval prolongation
  • Helpful if patient is taking other medications that may additively prolong QTc interval
Splitting methadone doses
  • Divide into 6- to 8-hour doses
  • Some programs may offer split-dose regimen, alternatively medical provider may need to prescribe remaining doses
If additional methadone not possible
  • Additional medication alternatives
    • Gabapentin for neuropathic pain
    • NSAIDs for musculoskeletal pain
    • Additional opioid
Acute exacerbations of pain (“breakthrough”)
  • Use small amount of short-acting opioids

Table 8
Treating PLWH and Chronic Pain Who Are Taking Buprenorphine

Recommendation Comments/Details
Use adjuvant therapy for mild-to-moderate breakthrough pain
  • Includes nonpharmacologic treatments, steroids, nonopioid analgesics, and topical agents
Increase dosage of buprenorphine
  • Increase in divided doses as an initial step
If maximal dose of burprenorphine is reached
  • Add long-acting potent opiod (eg, fentanyl, morphine, hydromorphone)
If additional opioid is ineffective
  • Closely monitor trial of higher doses
If there is inadequate analgesia
  • Transition patient to methadone maintenance

Table 9
Recommended Instruments for Screening Common Mental Health Disorders in PLWH and Chronic Pain

Recommendation Comments/Details
Review patient’s baseline mental status for modifiable risk factors
  • Self-esteem/coping skills
  • Recent major loss/grief
  • Unhealthy substance use
  • History of violence/lack of safety in the home
  • Mood disorders
  • Serious mental illness/suicidal ideation
Screen patients for depression
  • 2-question screen
    • During past 2 weeks have you been bothered by feeling down, depressed, hopeless?
    • During past 2 weeks have you had little interest/pleasure in doing things?
    • If affirmative, ask if patient would like help
Use screening tool
  • Patient Health Questionnaire-9 (PHQ-9) recommended
Screen for comorbid neurocognitive disorders
  • Includes frequent memory loss, slower reasoning, planning activities, or solving problems, difficulties paying attention
Neuropsychiatric evaluation
  • Recommended for all patients with chronic pain to establish baseline capacity
