“…In patients with polyneuropathy, H reflex studies allow conduction across proximal segments to be contrasted with conduction across the more distal segments studied in routine nerve conduction studies (e.g., Guiheneuc and Bathien, 1976, Panayiotopoulos and Lagos, 1980, Lachman et al, 1980, Ackil et al, 1981). Reflex studies may be particularly useful in acute inflammatory demyelinating polyradiculoneuropathy (Vucic et al, 2004).…”

HighlightsH reflexes can be obtained from many upper and lower limb muscles (e.g., tibialis anterior, the thenar muscles and forearm extensors) during a voluntary contraction of the test muscle.The contraction raises motoneuron excitability and decreases the Ib limitation on the reflex.H reflexes recorded at rest from muscles for which no reflex can normally be demonstrated is evidence of hyperreflexia, raising suspicion of ALS if there is denervation in that muscle.

“…Abd El Naby et al ]14[ study found that 22% of people had peripheral neuropathy. a scanty previous case series had shown prevalence of polyneuropathy extending from 0% to 59% according to Ackil et al [17] and Elzouki and collegues [18]. On comparison to the results of previous studies conducted on adult population with CKD, Chao and collegues [10] demonstrated that 37.5 % of patients has peripheral neuropathy , and Ezzeldin et al [19] in their study observed that 55% of the studied patients has clinically manifested polyneuropathy.…”

Background: One of the heterogeneous chronic diseases affecting the kidneys is chronic kidney disease (CKD). Patients with chronic kidney disease, which is associated with high morbidity and mortality, are more likely to experience nervous system problems. Objective: This work was performed to estimate the prevalence and predictors of peripheral neuropathy in children with End Stage Renal Disease (ESRD) on hemodialysis. Patient and methods: A total of 80 children from Egypt were recruited and divided into 2 separate groups. As a first step, a case group of 40 children (5-18 years old) with ESRD who were receiving regular hemodialysis was established. Besides the control group of 40 healthy children matched by age and gender to the case group. We subjected all the participants to detailed history taking stressing on duration of dialysis, family history of renal diseases, consanguinity and history of neuromuscular symptoms such as distal paresthesia, or muscle weakness. General examination for weight, height, blood pressure, vital signs, systemic examination including: Heart examination, chest, abdominal and neurological examination. Routine laboratory investigations and nerve conduction studies were done. Results: We found a statistically significant difference in weight and height between the two studied groups. 40% of patients had polyneuropathy. Multivariate analysis showed that longer disease duration (7 years), high parathyroid hormone level and high ferritin were independent predictors of polyneuropathy. Conclusion:Peripheral neuropathy is a common complication among children with end stage renal disease. Longer dialysis duration, high ferritin and parathormone levels were considered strong predictors of polyneuropathy among CKD patients.

Neurophysiologic parameters and symptoms in chronic renal failure

et al. 2002

We studied: (1) the sensitivity of various neurophysiologic parameters in the diagnosis of uremic polyneuropathy, (2) the relationship between subjective symptoms and neurophysiologic parameters, and (3) the effect of a single hemodialysis on the neurophysiologic parameters in 21 patients undergoing hemodialysis. The following parameters were studied: sensory and motor nerve conduction, including F-wave parameters; vibration detection thresholds; and thermal thresholds. The clinical findings and subjective symptoms were studied using a standardized questionnaire. The most sensitive parameters in the diagnosis of uremic neuropathy were F-wave parameters from lower limbs, vibration detection thresholds from the feet, and the sural nerve sensory action potential amplitude. The nerves from the upper extremities on the side of the fistula should not be used in the diagnosis of uremic polyneuropathy due to numerous mild local nerve lesions. The positive neuropathic symptoms correlated with quantitative vibratory detection thresholds and sensory nerve conduction studies, especially the amplitude of the sensory nerve action potential in the sural nerve. We found no significant change in any of the neurophysiologic parameters following a single hemodialysis session.
