صلاحية فحوصات الفسلجة العصبية بتنبؤ شدة متلاكمة غوليان باري وباستحقاق التنفس الاصطناعي Validity of neurophysiological study in prediction of severity of Guillain - Barre syndrome and the indication for mechanical ventilation

المستخلص: Guillain - Barre syndrome is an acute monophasic, non - febrile postinfectious illness manifesting as ascending weakness, and areflexia.However, sensory, autonomic and brainstem abnormalities may also seen. It is one of the most common causes of acute motor paralysis. In addition to the clinical presentation, those patients may develop neurophysiological features suggestive of demyelinating neuropathy.However, an axonal form had been reported. Hence, the importance of electrophysiological study; nerve conduction study (NCS) and electromyography (EMG) in the neurological evaluation of the severity of Guillain - Barre syndrome and the indication for mechanical ventilation.This study aimed to evaluate the neurophysiological study in prediction the severity of GBS, assess the usefulness of neurophysiology in prediction of respiratory muscles involvement and find out whether the neurophysiological study of peripheral nerves can predict the indications of mechanical ventilation.Two groups of patients are involved in this study. 22 Patients with GBS in the neuromedical wards and 18 patients in the respiratory care units (RCU).The mean age of the two groups were (47+\ - 24 years) with female predominance (1.22 : 1).Each patient submitted to brief medical history, clinical examination and neurophysiological study. This study was conducted at the neuromedical wards and RCU departments of Hospital of neurosciences, Baghdad and ALyarmuk teaching hospitals in a period from December 2017 to June 2018.The neurophysiological assessments involve the following tests : 1. Sensory NCS of bilateral median, ulnar and sural nerves involve sensory latency and sensory nerve action potential (SNAP). 2. Motor NCS of bilateral median, ulnar, common peroneal and tibial nerves involve the motor latency, compound motor action potential (CMAP), motor nerve conduction velocity (MNCV), conductions block and temporal dispersion.3. Minimal F wave latency of bilateral median, ulnar, common peroneal and tibial nerves.4. Needle EMG for bilateral proximal and distal muscles of upper (first dorsal interosseous) and lower limbs (tibialis anterior and extensor digitorium brevis) in which insertional activity, spontaneous activity, motor unit action potential MUAP and interference pattern were applied.The results of this study reveal that F wave and distal motor latencies of the left median, left ulnar, left peroneal, left tibial, right ulnar, right peroneal and right tibial nerves are significantly different between studied groups. Where there are prolonged latencies which could be considered as an indicator for admission to the RCU.Moreover, the reduced compound motor action potential (CMAP) and decrease conductive velocity (CV) in nearly all nerves are significantly different between studied groups and can also increase the chance for admission to the RCU.Concerning sensory abnormalities recorded in this study there are a reduced sensory nerve action potential of left median nerve or a prolonged left ulnar sensory latency when compared to the right ulnar and median sensory study and also increase the risk for admission to the RCU. Interestingly, what was noticed in this study, there are asymmetrical findings in nerve conductive parameters of the same patient involving not only the motor nerves rather than the sensory nerves too.This study concluded that the neurophysiological study can predict the severity of Guillain - Barre syndrome mainly the prolongation of F wave and motor latencies. The peripheral neurophysiological findings are useful in prediction of respiratory muscles involvement by GBS depending on CMAP and conductive velocity. There are asymmetrical finding changes in the studied neurophysiological parameters more apparently involving the sensory nerves of the same patients. Extremes of an age (<30yrs and >50yrs) represent a risk factor if not an indicator for RCU admission.

التقييم الكهروفسلجي للانواع الفرعيه لمتلازمة غوليان - باريه لشريحه من الاطفال العراقيين ELECTROPHYSIOLOGICAL ASSESSMENT OF GUILLAIN - BARRE SUBTYPES IN A SAMPLE OF IRAQI CHILDREN

المستخلص: Guillain - Barre syndrome represents the most common cause of acute motor paralysis in children. It is clinically characterized by an acute non - febrile, post - infectious illness marked as ascending weakness, and areflexia. However; sensory, autonomic and brainstem abnormalities may also be seen.This study aimed to assess the role of electrophysiological study (NCS and EMG) in the diagnosis of Guillain - Barre syndrome subtypes in children, estimate the frequency of subtypes whether demyelinating or axonal form of Guillain - Barre syndrome and match the electrophysiological results with the findings of CSF protein analysis.Two groups of either sex are involved in this study, children with Guillain - Barre (19 males and 11 females) with a mean age of (5 ± 2) years and normal healthy children served as control group (16 males and 14 females) matched for gender and age with a mean age of (6 ± 3) years. Each child submitted to medical history, brief clinical examination, and electrophysiological study. This study was performed at the unit of neurophysiology of Baghdad teaching hospital and Nursing house hospital in a period from December/2015 to June/2016.The electrophysiological assessments involve the following tests : 1 - Sensory NCS for bilateral median, right ulnar and bilateral medial plantar nerves in which latency, sensory nerve action potential amplitude (SNAP) and sensory nerve conduction velocity (SNCV) were studied.2 - Motor NCS for bilateral median, right ulnar and bilateral common peroneal nerves (fibular nerve) in which, distal motor latency (DML),compound muscle action potential amplitude (CMAP), motor nerve onduction velocity (MNCV), conduction block and temporal dispersio were performed.3 - Minimal F - wave latency for bilateral median, right ulnar and bilateral fibular nerves.4 - H - reflex latency of bilateral tibial nerve.5 - Needle EMG for bilateral proximal and distal muscles of upper (first dorsal interosseous) and lower limbs (tibialis anterior and extensor digitorum brevis) in which insertional activity, spontaneous activity, motor unit action potential MUAP and interference pattern were applied.The results of this study revealed that acute inflammatory demyelinating polyneuropathy (AIDP) is the most frequent subtype followed by acute motor axonal neuropathy (AMAN) and acute motor sensory axonal neuropathy (AMSAN) respectively. Children with an age (3 - 6) years among other age groups are more vulnerable to develop GBS following infection in the preceding 3 months.The sensory nerve parameters (sensory latency is prolonged, SNAP is reduced and SNCV is slowed) are significantly changed between GBS children and control groups.The motor nerve parameters (DML is prolonged, CMAP is reduced and MNCV is slowed) are significantly changed between GBS children and control groups. Moreover among the GBS subtypes, there were significant differences in which the prolonged (DML) mostly in AIDP subtype, while the reduced (CMAP) mostly in axonal subtype was reported.Concerning minimal F - wave, it was absent in lower limbs more than upper limbs (46.6% and 26.6% respectively). Whereas H - reflex was absent in (73.3%) of children.Needle EMG had showed reduced recruitment in all GBS subtypes in addition to the evidence of spontaneous activity particularly in axonal subtype.In conclusion, this study detected that the AIDP was the most frequent subtype of GBS compared to others. Motor nerve conduction study is more useful than sensory nerve conduction study in GBS subtyping.Additionally Late responses (minimal F - wave and H - reflex) are very informative in the early course of the disease since they reflect the involvement of proximal nerve segment, which is more vulnerable to demyelination than terminal and intermediate nerve trunk segments, in addition CSF protein analysis showed no significant differences between GBS subtypes.
