- 47. Case Discussion
- 49. Myasthenia Gravis Neuromuscular disorder characterized by weakness and fatigability of skeletal muscles Underlying defect - ↓ in number of available acetylcholine receptors (AChRs) at neuromuscular junctions due to an antibody-mediated autoimmune attack Myasthenic crisis - Severe weakness of bulbar (innervated by cranial nerves) and/or Respiratory muscles, enough to cause inability to maintain adequate ventilation and/or permeability of upper airways, causing respiratory failure that requires artificial airway or ventilator support
- 50. Standard treatment Anticholinesterase medication Thymectomy Immunosuppression – glucocorticoids or others Plasmapheresis and IV Immunoglobulins
- 52. Rationality Anticholinesterase medication Inj neostigmine 0.5mg BD Tab /Inj pyridostigmine 60 mg TDS Use – rational Improve muscle contraction - Ach released from prejunctional endings to accumulate and act on receptors over a larger area, as well as by directly depolarizing endplate Whether combination can be used is not given in any text book
- 53. Rationality Anticholinergic drugs Inj atropine 0.6mg before neostigmine Use – rational To avoid muscarinic side effects of anticholinesterase drug
- 54. Corticosteroids / Immunosuppresion Inj methyl prednisolone 15- 25mg /day in single dose to avoid side effects Use – Rational Inhibit production of Nicotinic Receptor (NR)- antibodies & may ↑ synthesis of NRs Dose ↑ stepwise - by 5 mg/d at 2- to 3-day intervals → marked Clinical improvement or dose of 50 - 60 mg/d reached This dose maintained for 1 - 3months Alternate-day regimen over course of 1 -3 months Goal is to ↓ dose on off day to zero or to minimal level
- 55. Rationality Tab azathioprine 50mg OD Use – Rational Previously most commonly used immunosuppressive agent because of its Relative safety Long track record Therapeutic effect may add to glucocorticoids effect &/or allow glucocorticoid dose to ↓
- 56. Rationality Plasmapheresis Use – rational Plasma contains pathogenic antibodies, is mechanically separated from blood cells Course of 5 exchanges (3 - 4 L per exchange) - Over 10 to 14 day period Advantages in Our set up – Comparatively inexpensive to IVIg but requires expertise
- 57. Rationality Intravenous immunoglobulins Use – rational Advantage Doesn’t require special equipment & Large-bore venous access Ease of administration Disadvantage – expensive Usual dose is 2 g/kg - over 5 days (400 mg/kg per day)
- 58. Rationality Antibiotics Inj ceftriaxone 1gm iv BD Inj levofloxacin 0.5gm iv BD Inj piperacillin tazobactum 4.5 gm TDS Cap amoxicillin clavulunate 625mg BD Use – rational Most common cause of crisis is intercurrent infection
- 59. Rationality Tab thyroxine 100µg OD Use – rational Hypothyroidism Inj KCl 10-20meq/hr Use – rational To treat hypokalemia Inj calcium gluconate 90mg iv over 10 min post plasma pheresis Use – rational To treat hypocalcemia associated with plasmapheresis
- 60. Not rational Prednisolone dose on admission should have been increased Brand names were used Respiratory secretions – culture and sensitivity was done late Instead of ceftriaxone they could have used ceftazidime and cefoperazone
- 61. Not rational Culture and sensitivity of drugs given was not done Urine & blood culture & sensitivity was not done At some places doses and route of administration were missing
- 62. Next – CCD – DR Swarnank Parmar
- 63. Management of myasthenic crisis exacerbation of weakness sufficient to endanger life (usually consists of respiratory failure caused by diaphragmatic & intercostal muscle weakness) Crisis rarely occurs in properly managed patients Intensive care units staffed with teams experienced in the management of MG, respiratory insufficiency, infectious disease, fluid & electrolyte therapy Deterioration could be due to excessive anticholinesterase medication (cholinergic crisis) - best excluded by temporarily stopping anticholinesterase drugs
- 64. most common cause of crisis is intercurrent infection This should be treated immediately, because the mechanical and immu-nologic defenses of the patient can be assumed to be compromised. The myasthenic patient with fever & early infection should be treated like other immunocompromised patients. Early & effective antibiotic therapy, respiratory assistance (preferably noninvasive, using bilevel positive airway pressure), & pulmonary physiotherapy are essentials of the treatment program As discussed above plasmapheresis or IVIg is frequently helpful in hastening recovery
