TC(1035).(05).Orthopedics Case No 113:- Tuberculosis spine / Pott’s disease

Tuberculosis spine / Pott’s disease — মূল কথা

Pott’s disease হলো Mycobacterium tuberculosis দ্বারা spine-এর vertebral body/disc/adjacent soft tissue-এর infection—অর্থাৎ extrapulmonary skeletal TB। সাধারণত lung থেকে blood stream দিয়ে bacilli spine-এ যায়, vertebra destroy করে, paravertebral/epidural abscess, kyphosis এবং spinal cord compression করতে পারে।

Medical caution: নিচের dose adult average guidance। Pregnancy, liver disease, CKD, HIV/ART, diabetes, elderly, child, drug resistance, neurological deficit—এসব থাকলে NTP/Chest specialist/ID/Spine surgeon অনুযায়ী individualize করতে হবে।

1) Definition — সংজ্ঞা

  • বাংলায় সংজ্ঞা:
    Pott’s disease হলো spine-এর vertebra-তে TB infection, যেখানে সাধারণত দুইটি adjacent vertebral body ও intervertebral disc আক্রান্ত হয়; পরে vertebral destruction, collapse, cold abscess, kyphosis এবং spinal cord/nerve root compression হতে পারে।
  • Clinical term:
    Tuberculous spondylitis / spinal tuberculosis / Pott spine।

2) Cause / Etiology — কারণগুলো

  • মূল জীবাণু:
    Mycobacterium tuberculosis।
  • কীভাবে spine-এ যায়:
    • Pulmonary TB focus থেকে hematogenous spread হয়ে vertebral body-তে পৌঁছায়।
    • Batson venous plexus/arterial route দিয়ে thoracic ও lumbar spine বেশি আক্রান্ত হয়।
  • Risk factor:
    • Active pulmonary TB contact
    • Previous TB বা incomplete ATT
    • HIV/immunosuppression
    • Diabetes mellitus
    • Malnutrition
    • CKD, steroid/biologic therapy, transplant
    • Crowded living condition
    • Alcohol/substance use
    • Low socioeconomic status
  • Pathophysiology সহজভাবে:
    Bacilli vertebral body-তে granulomatous inflammation করে → caseous necrosis → bone destruction → disc space narrowing/collapse → paravertebral বা psoas abscess → kyphosis/gibbus → epidural extension হলে cord compression/paraplegia।

3) Symptoms — লক্ষণগুলো

A. Local spine symptoms

  • Persistent back pain
    সবচেয়ে common symptom; সাধারণ mechanical back pain-এর মতো বিশ্রামে কমে না, রাতে/দীর্ঘদিন থাকে।
  • Localized tenderness
    আক্রান্ত vertebral level-এ pressure দিলে pain।
  • Spinal stiffness / movement restriction
    রোগী spine বাঁকাতে পারে না, muscle spasm থাকে।
  • Kyphosis / gibbus deformity
    Vertebral collapse হলে পিঠ বাঁকা বা hump দেখা যায়।
  • Paraspinal swelling / cold abscess
    Pain ছাড়া soft swelling হতে পারে; lumbar disease হলে psoas abscess groin/thigh-এ নামতে পারে।

B. Constitutional TB symptoms

  • জ্বর—সাধারণত low-grade evening rise
  • Night sweat
  • Weight loss
  • Loss of appetite
  • Fatigue, malaise
  • TB contact history থাকতে পারে

C. Neurological symptoms — emergency red flag

  • Leg/hand weakness
  • Numbness/tingling
  • Radicular pain
  • Gait disturbance
  • Hyperreflexia/spasticity
  • Bladder/bowel involvement
  • Paraplegia/quadriparesis

Pott’s disease-এ back/neck pain, limb weakness, fever, anorexia ও unexplained weight loss common; untreated হলে nerve compression, walking difficulty, paralysis, kyphosis, abscess ও disseminated disease হতে পারে।

4) Clinically diagnosis — clinically কীভাবে সন্দেহ করবেন

Strong clinical suspicion হবে যদি—

  • Back pain >2–3 weeks, especially night pain/rest pain
  • Fever, weight loss, night sweat থাকে
  • TB contact বা previous TB history থাকে
  • Spine tenderness + stiffness + deformity
  • ESR/CRP high
  • Neurological deficit
  • MRI suggestive of infection
  • Paravertebral/psoas abscess
  • Pulmonary TB evidence বা extrapulmonary TB history

Clinical examination checklist

  • Spine inspection: kyphosis/gibbus, scoliosis, swelling
  • Palpation: localized tenderness, paraspinal spasm
  • Range of motion: restricted flexion/extension
  • Neurological exam:
    • Power, tone, reflex
    • Sensory level
    • Plantar response
    • Gait
    • Bladder/bowel function
  • General exam: lymph node, chest signs, malnutrition, fever
  • Look for differential clues: malignancy, pyogenic infection, brucellosis, fungal infection

5) Specific investigations — কী কী test করবেন

A. Imaging

  • MRI spine with contrast — investigation of choice
    Specific findings:
    • Vertebral marrow edema
    • Endplate destruction
    • Disc involvement/narrowing
    • Subligamentous spread
    • Paravertebral/psoas abscess
    • Epidural abscess
    • Spinal canal compromise
    • Cord compression
    • Kyphosis/collapse
      MRI early diagnosis ও neural/soft tissue involvement দেখার জন্য সবচেয়ে useful।
  • X-ray spine AP/lateral
    Late findings: vertebral collapse, disc space narrowing, kyphosis, paravertebral shadow।
  • CT scan spine
    Bony destruction, sequestrum, calcified abscess, surgical planning এবং CT-guided biopsy-এর জন্য ভালো।

B. Microbiological confirmation — must try

Bangladesh NTP SOP অনুযায়ী extrapulmonary TB diagnosis pulmonary TB-এর চেয়ে কঠিন এবং অনেক সময় tissue/fluid specimen দরকার; lymph node/other tissue specimen-এ Xpert MTB/RIF conventional microscopy/culture/histopathology-এর replacement/add-on test হিসেবে ব্যবহারযোগ্য।

  • CT-guided biopsy / aspiration from vertebral lesion, paravertebral abscess, psoas abscess:
    • AFB smear
    • GeneXpert MTB/RIF or Xpert Ultra
    • Mycobacterial culture — MGIT/LJ
    • Drug susceptibility test — DST
    • Histopathology: caseating granuloma, Langhans giant cells
    • Bacterial/fungal culture if differential suspected
  • Why tissue diagnosis important:
    Spinal TB clinically/radiologically malignancy, pyogenic spondylodiscitis, brucellosis, lymphoma mimic করতে পারে। Xpert MTB/RIF rifampicin resistance detect করতে পারে; culture sensitivity low হলেও DST-এর জন্য valuable। BMC Infectious Diseases study-তে Xpert MTB/RIF specificity 100% এবং rifampicin resistance detection clinically useful বলা হয়েছে।

C. Blood tests

  • CBC
  • ESR, CRP — baseline ও follow-up trend
  • LFT: ALT/AST, bilirubin, alkaline phosphatase
  • RFT: serum creatinine/eGFR
  • Uric acid — pyrazinamide-এর কারণে rise হতে পারে
  • Fasting glucose/HbA1c
  • HIV test
  • HBsAg, anti-HCV if hepatotoxicity risk
  • Pregnancy test where relevant

D. Pulmonary TB evaluation

  • Chest X-ray
  • Sputum AFB smear/GeneXpert/culture if cough/sputum/chest lesion
  • Contact screening

E. Supportive tests

  • TST/IGRA: supportive; active spinal TB confirm করে না।
  • Baseline visual acuity + colour vision: ethambutol শুরু করার আগে এবং follow-up-এ।

6) Differential diagnosis

  • Pyogenic spondylodiscitis
  • Brucellar spondylitis
  • Spinal metastasis
  • Multiple myeloma
  • Lymphoma
  • Fungal vertebral osteomyelitis
  • Degenerative disc disease
  • Epidural abscess
  • Ankylosing spondylitis
  • Vertebral fracture/osteoporotic collapse

7) Complications — রোগের জটিলতা বাংলায়

  • Paravertebral / psoas abscess:
    Spine-এর পাশে pus জমে; lumbar disease হলে pus psoas muscle দিয়ে groin/thigh পর্যন্ত যেতে পারে।
  • Epidural abscess:
    Spinal canal-এর ভেতরে pus জমে cord/nerve চাপ দেয়।
  • Spinal cord compression:
    Weakness, numbness, gait disturbance, bladder-bowel problem হতে পারে।
  • Paraplegia/quadriparesis:
    Cord compression untreated থাকলে permanent paralysis হতে পারে।
  • Kyphosis/gibbus deformity:
    Vertebra collapse হয়ে spine বাঁকা হয়ে যায়; cosmetic deformity ছাড়াও late neurological deficit দিতে পারে।
  • Spinal instability:
    Vertebra destroy হলে spine unstable হয়; severe pain ও neurological risk বাড়ে।
  • Chronic pain ও disability:
    দীর্ঘদিন pain, stiffness, reduced mobility।
  • Sinus formation:
    Abscess skin পর্যন্ত track করলে chronic discharging sinus হতে পারে।
  • Drug-resistant TB:
    Irregular treatment/poor adherence হলে MDR/RR-TB হতে পারে।
  • Dissemination:
    Untreated disease brain, kidney বা other organs-এ spread করতে পারে।

8) Treatment management — guideline-based

A. Core management principles

  • Do not treat as simple back pain if red flags present।
  • Tissue diagnosis নেওয়ার চেষ্টা করুন before ATT, কিন্তু severe neurological deficit/cord compression হলে treatment delay করবেন না।
  • Manage under NTP/DOTS + Chest/ID + Spine surgery team।
  • Drug-sensitive হলে first-line ATT backbone: HRZE intensive phase → HR continuation phase। WHO 2022 guideline standard 2HRZE/4HR regimen pulmonary TB-এর জন্য strong recommendation দিয়েছে, তবে CNS, bone/joint TB-তে কিছু expert longer therapy suggest করেন।
  • WHO 2025 Module 4 treatment and care সব current DS-TB/DR-TB recommendations একত্র করেছে।

B. Duration — কতদিন ATT?

  • Minimum: 6 months: 2 months HRZE + 4 months HR
  • Spinal/bone TB practical duration: commonly 9–12 months, especially যদি—
    • Extensive vertebral destruction
    • Large abscess
    • Neurological deficit
    • Slow clinical/CRP response
    • HIV/immunosuppression
    • Delayed diagnosis
    • Incomplete source control
    • Drug resistance concern
  • Cleveland Clinic notes continuation with INH/RIF may be 4–12 months or longer depending on case.

C. Surgery indications

Surgery সব patient-এর লাগে না। Indications:

  • Progressive or severe neurological deficit
  • Cord compression with weakness/bladder-bowel involvement
  • Spinal instability
  • Severe/progressive kyphosis
  • Large epidural/paravertebral/psoas abscess not responding/drainage needed
  • Intractable pain
  • Diagnostic uncertainty or biopsy required
  • Failure of medical treatment
  • Severe deformity needing correction/stabilization

Surgical options: abscess drainage, debridement, decompression, stabilization, instrumentation/fusion। Surgery is generally reserved for neurological compromise, instability, severe deformity, refractory disease বা abscess.

    Routine নয়; neurological emergency/cord edema/TB meningitis-type indication থাকলে specialist decision।

11) Monitoring during treatment

  • Before ATT: CBC, LFT, RFT, uric acid, HIV, glucose/HbA1c, hepatitis screen if risk, pregnancy status, visual acuity/colour vision।
  • Monthly: adherence, weight, pain score, fever, neurological exam, adverse effects।
  • LFT repeat: symptoms বা liver risk থাকলে; jaundice/vomiting/severe anorexia হলে urgent।
  • ESR/CRP: baseline and trend।
  • MRI repeat: routine early repeat নয়; worsening neuro deficit, persistent fever/pain, rising CRP, no response after 8–12 weeks, surgery planning হলে।
  • Ethambutol monitoring: visual acuity/colour vision; blurred vision হলে stop and urgent review।
  • Drug resistance: Xpert rifampicin resistance positive বা clinical failure হলে PMDT/DR-TB regimen; empirical random second-line drug দেবেন না।

12) Prevention — কীভাবে প্রতিরোধ করবেন

  • Active pulmonary TB patient দ্রুত diagnose ও complete treatment।
  • Household contact tracing and screening।
  • High-risk contact/latent TB infection হলে guideline অনুযায়ী TB preventive therapy।
  • Cough etiquette, mask, good ventilation, overcrowding reduce।
  • BCG vaccination—especially childhood severe TB prevention।
  • Malnutrition correct, diabetes/HIV control।
  • ATT কখনো self-stop করবেন না; missed dose হলে NTP/doctorকে জানাবেন।
  • Rifampicin interaction: oral contraceptive failure হতে পারে—non-hormonal/additional contraception advise।
  • Follow-up না করলে deformity/paralysis risk বাড়ে।

Overview / Summary

  • Pott’s disease হলো spine-এর extrapulmonary TB, সাধারণত chronic back pain + constitutional symptoms + MRI changes দিয়ে suspect হয়।
  • MRI spine with contrast + CT-guided biopsy/aspiration for Xpert/culture/DST/histopathology হলো best diagnostic approach।
  • Drug-sensitive হলে treatment backbone: 2 months HRZE + HR continuation, spine diseaseে many cases 9–12 months require করতে পারে।
  • Surgery লাগে যদি neurological deficit, cord compression, instability, severe kyphosis, large abscess বা treatment failure থাকে।
  • Bangladesh-এ MedEx-listed practical brands: Rimstar 4-FDC, Rimactazid, Rifagen, Sural, Rifcin/Rimactane, Pyridoxine brands, analgesic/PPI/supportive brands—কিন্তু availability/stock prescribing date-এ verify করতে হবে।

Actionable Plan / Steps

  1. Suspect: chronic back pain >2–3 weeks + fever/weight loss/TB risk/neuro sign।
  2. Urgent MRI spine with contrast if red flag or persistent suspicion।
  3. Baseline labs: CBC, ESR/CRP, LFT/RFT, uric acid, HIV, glucose, visual test।
  4. Tissue confirmation: CT-guided biopsy/aspiration → AFB, Xpert MTB/RIF/Ultra, culture-DST, histopathology।
  5. Start ATT: HRZE intensive phase, then HR continuation; duration 6–12 months depending severity/response।
  6. Add supportive drugs only when indicated: pyridoxine routinely with INH; analgesic/PPI/calcium/muscle relaxant case-wise।
  7. Refer spine surgeon urgently if neuro deficit, cord compression, instability, large abscess, severe deformity।
  8. Monthly follow-up: adherence, side effects, neuro exam, ESR/CRP trend; repeat MRI if worsening/non-response।
