Clinical Assessment: 60-Year-Old Male, CKD on MHD - Abdominal "Khichav" (Stretching/Pulling Sensation) + Insomnia

Interpretation of "Khichav" in This Context

CAUSES (Pathophysiology)

• Reduced dopaminergic modulation of intracortical excitability with reduced supraspinal inhibition and increased spinal cord excitability
• Iron deficiency (common in dialysis) - iron is a cofactor for tyrosine hydroxylase (rate-limiting step in dopamine synthesis); disturbed iron storage in basal ganglia reduces dopamine receptor binding
• Uremic toxin accumulation
• Anemia (stimulates RLS)
• CKD-mineral bone disorder (abnormal Ca/PO4 metabolism)
• RLS affects 12-55% of hemodialysis patients (global meta-analysis, PMID 38376019)

• Autonomic neuropathy (particularly vagal) from diabetes or uremia
• Reduced gastric motilin receptor activation
• Leads to gastroparesis, early satiety, bloating/stretching feeling

• Axonal polyneuropathy due to uremic toxins
• Length-dependent, affects longest fibers first

INVESTIGATIONS

PRESCRIPTION / MANAGEMENT

A. For RLS / Khichav sensation + Insomnia:

• IV Iron sucrose (if ferritin < 200 or transferrin sat < 20%) - standard in MHD
• Optimize Hb with EPO/darbepoetin if Hb < 10 g/dL
• Correct Ca/PO4/Mg imbalances
• Optimize dialysis adequacy (target Kt/V ≥ 1.4)

Preferred in MHD: Gabapentin 100-200 mg post-hemodialysis (dialyzable, so give after session) is often practical and helps RLS + pruritus + insomnia simultaneously.

Note: Avoid pregabalin/gabapentin accumulation between sessions - dose after HD only.

B. For Gastroparesis/Abdominal Dysmotility (if contributing):

• Tab. Metoclopramide 10 mg before meals / at bedtime (prokinetic)
• Tab. Domperidone 10-20 mg TDS before meals
• Erythromycin 125-250 mg QID (motilin agonist) - short course only

C. For Constipation (if applicable):

• Lactulose 15-30 mL BD (osmotic laxative - safe in CKD)
• Bisacodyl 5-10 mg at bedtime
• Increase dietary fiber within fluid restrictions

D. For Sleep (adjunct):

• Melatonin 3-5 mg at bedtime (safe in CKD, minimal renal excretion)
• Treat underlying RLS first - sleep usually improves

Sample Prescription (Most Likely - RLS-dominant):

Rx:
1. Tab. Gabapentin 100 mg - 1 tab after hemodialysis session, at night
   (Give POST-dialysis session only; not between sessions)

2. Tab. Pramipexole 0.125 mg - 1 tab at 9 PM (1-2 hrs before sleep)
   Review after 2 weeks; may increase to 0.25 mg if needed

3. Inj. Iron Sucrose 200 mg IV - during next 3 HD sessions
   (after checking ferritin and transferrin saturation)

4. Melatonin 3 mg - at bedtime

5. Tab. Domperidone 10 mg TDS before meals
   (if abdominal bloating/gastroparesis component)

Advice: Avoid caffeine in evening, gentle leg stretching before sleep
Follow up: After next HD session

Key Points to Remember in MHD Patients:

• Iron deficiency must be corrected before or alongside drug therapy for RLS
• Gabapentin must be dosed only after dialysis (it is removed by HD, so inter-dialytic accumulation is avoided, but post-HD dosing provides next-session relief)
• Augmentation (worsening/earlier onset with dopaminergic drugs long-term) is a risk - switch to gabapentin/pregabalin if it occurs
• Optimize dialysis adequacy - better clearance reduces uremic RLS
• RLS often partially improves after renal transplantation

Updated Clinical Context - Additional History:

Since iron is being replaced with FCM, the dopamine pathway deficiency still persists acutely - pharmacological symptom relief is needed NOW until investigations complete.

FAST SYMPTOM RELIEF - Empirical Prescription

Goals:

1. Stop the khichav/stretching sensation immediately (tonight)
2. Restore sleep tonight
3. Address diabetic gastroparesis component of abdominal symptoms
4. Safe in HCV + CKD + MHD context

PRESCRIPTION WITH INDIAN BRAND NAMES

Rx 1 - FOR RLS / KHICHAV (Primary Symptom) - FASTEST RELIEF TONIGHT

Pramipexole is first choice for FASTEST relief - dopamine agonist directly reverses the dopaminergic deficit causing RLS. Start at 0.125 mg, increase to 0.25 mg after 3-4 days if needed.

Rx 2 - FOR SLEEP (Tonight itself)

Use Meloset (Melatonin) + Lonazep 0.25 mg together for tonight's sleep - immediate and safe.

Rx 3 - FOR ABDOMINAL KHICHAV (Gastroparesis Component - DM2)

Domstal preferred over Metoclopramide in this patient - Metoclopramide has CNS side effects and may worsen Parkinsonism-like symptoms from Pramipexole.

Rx 4 - NERVE PAIN / NEUROPATHY (Diabetic + Uremic)

Critical: Gabapentin is removed by dialysis, so give only after the hemodialysis session ends - NOT between sessions. This prevents accumulation and toxicity.
