Clinical Analysis: Shameem Mohammed Thaha, 68F

1. Summary of the Clinical Course

2. The MRI Report (March 13, 2025) — Critical Findings

What the MRI Shows

• Plate and screw fixation at L4-5 and S1
• Mild spondylolisthesis at L4–5
• L4–5 disc collapse and destruction with irregular, stippled pattern on CT
• Hyperintense T2 fat-sat signal in the disc area

• Total alteration in disc morphology — expanded disc with bony fragments scattered through
• Moth-eaten pattern in the lower endplate of L5 and upper endplate of S1 on CT
• Numerous high-density foci in the IV disc space (CT)
• Disc obliterating the neural foramen with nerve root compression
• Heterogeneous signal throughout vertebral bodies

Radiologist's Impression (Dr. K.S. Manoj, DMRD, MD, DNB-RD)

1. Infective / granulomatous discitis (e.g., pyogenic or tubercular spondylodiscitis)
2. Post-surgical changes with bony endplate involvement
3. Osteopenia with trabecular loss

3. The Most Important Concern: Possible Post-Surgical Spondylodiscitis

• Pyogenic (bacterial, often Staphylococcus aureus) — common post-operatively
• Tubercular (Pott's disease) — relevant in the Indian subcontinent

• If an active infection is present at the surgical site and was not identified before the revision surgery in March 2025, the revision surgery may have been performed into an infected field.
• Post-surgical discitis can cause persistent neuropathic/burning pain that does not respond to physiotherapy or epidural steroids.
• Untreated, it can lead to hardware failure, vertebral collapse, and irreversible neurological damage.

4. Understanding the Persistent Burning Pain

5. What Has NOT Been Addressed (Gaps in Management)

Urgent — Rule Out Infection

• ESR and CRP — elevated in spondylodiscitis
• CBC with differential — leukocytosis in pyogenic infection
• Blood cultures — if fever is present
• Serum TB tests / Mantoux / IGRA — for tubercular discitis, very relevant in Kerala/India
• Bone scan (Tc-99m) or FDG-PET/CT — as the radiologist suggested, highly sensitive for infective/inflammatory bone pathology
• CT-guided disc space biopsy — if infection is suspected and non-invasive workup is inconclusive

Neurological Assessment

• NCV/EMG — the radiologist recommended this. It will quantify the degree of nerve damage at L5/S1, distinguish axonal vs. demyelinating injury, and guide prognosis for recovery of muscle strength.

Hardware Assessment

• Is the hardware (plates/screws) still intact and well-positioned? Screw loosening or migration can cause persistent pain. A plain X-ray or CT of the lumbar spine in the current state would help.

Gabapentin Dosing

• The current dose of 400 mg/day is far below the therapeutic range for neuropathic pain. Standard dosing for neuropathic pain is 900–3600 mg/day in divided doses. The dose should be carefully titrated upward (with monitoring for sedation, falls risk in a 68-year-old) under physician supervision.

6. Recommended Next Steps (Priority Order)

1. Immediate blood work: CBC, ESR, CRP, LFT/KFT (before medication changes), blood cultures if febrile. Share these results with the treating spine surgeon urgently.
2. Bone scan or FDG-PET/CT: As recommended by the radiologist — to rule out active infective/inflammatory process at L4–5 and L5–S1.
3. NCV/EMG study: To assess the functional status of L4, L5, S1 nerve roots and determine if there is active denervation or chronic nerve damage.
4. Specialist consultation: A spine infectious disease specialist or an orthopedic spine surgeon at a tertiary center (e.g., SCTIMST Trivandrum, Amrita Institute Kochi) should review the MRI and clinical picture together. The current MRI findings are serious enough to warrant this.
5. Do not continue indefinitely with physiotherapy alone: While physiotherapy helps with muscle strengthening and is appropriate, if there is an underlying infective or structural cause at L5–S1, physiotherapy will not resolve it.
6. Gabapentin titration: Discuss with the treating physician about gradually increasing to 900–1800 mg/day (in divided doses, with caution given age 68 — fall risk, sedation).
7. Spinal cord stimulation (SCS): If all structural and infective causes are excluded and the diagnosis is confirmed as FBSS with neuropathic pain, SCS is a well-established evidence-based intervention for this condition and may be worth exploring.

7. A Note on the Ayurveda/Panchakarma

• These treatments address inflammation and muscle conditioning — they cannot resolve structural nerve compression or treat active infection.
• They are a valuable adjunct but not a substitute for addressing the underlying pathology identified on MRI.

Lab Results Analysis (05/03/2026) — In Full Context

Patient: Shameem Mohammed Thaha, 69F

Complete Lab Summary

Interpretation of Abnormal Values

1. 🔴 ESR = 60 mm/hr (Markedly Elevated — 3× Upper Limit of Normal)

• Sjögren's syndrome itself characteristically causes elevated ESR — Harrison's confirms that in two-thirds of Sjögren's patients, elevated ESR, hypergammaglobulinemia, and antinuclear antibodies are detected (Harrison's, p. 10152). So Sjögren's disease activity alone can explain a raised ESR.
• However, in this patient's context — with the MRI showing moth-eaten endplates, disc destruction at L4–5 and L5–S1, and a radiologist raising the possibility of infective discitis — an ESR of 60 is a significant red flag that cannot be dismissed as Sjögren's alone.
• An ESR of 60 in a post-surgical patient with spinal hardware and destructive bony changes on MRI raises genuine concern for post-surgical spondylodiscitis or granulomatous infection (TB).

2. 🔴 WBC = 11,600/µL with Absolute Lymphocytosis (4,640/µL)

• Total WBC elevated, but the differential is not neutrophil-dominated
• Neutrophils are within range (6,500/µL — normal upper limit 7,000)
• The elevation is driven by absolute lymphocytosis (4,640 vs. upper limit 3,000)

• Viral infection / reactive lymphocytosis
• Active autoimmune disease (Sjögren's-associated lymphocytic infiltration)
• Drug effect — Iguratimod can occasionally cause hematological changes
• Sjögren's syndrome is itself associated with lymphocytic hyperactivation; elevated absolute lymphocyte counts are well-recognized

3. ⚠️ HbA1c = 5.9% (Pre-diabetic range)

• The patient is in the pre-diabetic range (5.7–6.4%) per ADA 2021 guidelines
• This is a new and important finding given:
  • Iguratimod has been associated with effects on glucose metabolism in some reports
  • Steroids (ESIs received in 2024) cause transient hyperglycemia; repeated ESIs can push susceptible patients toward glucose dysregulation
  • Sjögren's syndrome has an increased association with autoimmune endocrine disorders including Type 1 diabetes
  • Pre-diabetes increases infection risk, impairs wound healing, and may contribute to neuropathic pain (small fiber neuropathy from glucose toxicity can cause burning pain remarkably similar to radicular pain)
• Action needed: Fasting plasma glucose, post-prandial glucose. Lifestyle intervention (diet, walking when able). Inform treating physician. Re-check HbA1c in 3 months.

4. Liver and Kidney Function — Reassuringly Normal

• LFTs (AST 17, ALT 16, ALP 68, Bilirubin 0.51) are all within normal range — Iguratimod is not causing hepatotoxicity at this point. This is important to confirm regularly since iguratimod carries a hepatotoxicity risk.
• Creatinine 1.01 is within the age-adjusted normal range — kidney function is intact, which is relevant for medication dosing (gabapentin is renally cleared).

Critical Integration: What These Labs Mean for the Full Clinical Picture

What Is Missing From This Lab Panel (Urgent Additions)

Urgent (infection workup):

• CRP (C-reactive protein) — far more sensitive than ESR for acute infection
• Blood cultures ×2 — if even low-grade fever is present
• Serum procalcitonin — distinguishes bacterial infection from inflammatory/autoimmune causes
• Serum ferritin — elevated in active autoimmune disease and infection

Sjögren's disease monitoring (overdue after 1-year gap):

• Anti-SSA/Ro and Anti-SSB/La antibodies — to assess autoantibody status
• ANA titres — baseline recheck
• Serum immunoglobulins (IgG, IgM, IgA) — Sjögren's patients have risk of lymphoma; elevated IgG can also drive ESR
• Serum protein electrophoresis (SPEP) — to rule out monoclonal gammopathy (Sjögren's carries increased multiple myeloma risk per Harrison's)
• Complement C3, C4 — low in active Sjögren's

Neuropathy workup:

• NCV/EMG — as recommended by radiologist; essential to characterize the nerve injury
• Fasting glucose + OGTT — given HbA1c 5.9%
• Vitamin B12 — deficiency causes burning neuropathy, common in elderly

Bone/infection:

• Bone scan (Tc-99m) or FDG-PET/CT — as recommended by radiologist

Sjögren's Syndrome: The Overlooked Contributor to Pain

"Most common is a length-dependent axonal sensorimotor neuropathy characterized mainly by sensory loss in the distal extremities... A pure small-fiber neuropathy... can also be seen."
