“…Bartel et al (1986) found I-III, III-V and I-V intervals uniformly distributed among the degrees of malnutrition, studying 22 children, also showing differences between the two ears, which was further supported by Odabas et al (2005). In the present sample we did not analyze the data for each ear.…”

“…Moreover, considering these two references, we found that among patients aged four to seven months, at admission and discharge, the values of latency of wave I were much higher than those of normal newborns, and that the two oldest patients (20 and 34 months of age) presented latencies of waves III and V around the values observed at 6 months age. Odabas et al (2005) reported increased wave latencies (mainly for wave I) at all degrees of malnutrition. These findings suggest that malnutrition early in life may have a more marked effect on the caudal myelination of the auditory pathway.…”

“…Evidence that malnutrition causes changes in AEP measurements in children has been provided sparsely in the literature (Barnet et al, 1978;Bartel et al, 1986;Durmaz et al, 1999;Odabas et al, 2005).…”

“…The children's height was mentioned by Barnet et al (1978), finding higher AEP waves amplitude in children with shorter stature. Other covariates, such as iron deficiency and albuminaemia, were analyzed by Odabas et al (2005), showing in malnourished infants with iron deficiency longer than controls the mean latency of wave I on the left side and the mean III-V interpeak on the right side; in malnourished infants without iron deficiency, the mean I-III interpeak on the right ear was longer than controls, and no difference was found between low and normal serum albumin within the malnourished groups.…”

“…Odabas et al (2005) mention the exclusion of SGA infants in their criteria for subject selection. In the present study, the five-month-old patient who was born SGA, was the only one presenting increased I-III interpeak interval and above the control values at 70 dBn HL, in both the admission and discharge AEP tracings, suggesting the need to examine the cochlear station since neonatal period for the SGA patients.…”

There is evidence that the auditory evoked potential (AEP) is altered by malnutrition both in laboratory animals and in humans. The objective of the present study was to determine whether changes in the AEP caused by malnutrition could be reversed by nutritional rehabilitation and sensorymotor and environmental stimulation during hospitalization. Six children aged 5-33 months with severe malnutrition (kwashiorkor, marasmus and marasmic-kwashiorkor) were admitted to the Pediatric Ward of a University Hospital. Normal age and sex-matched children from the hospital day-care center were enrolled as a control group. The AEP was tested in an electrically and acoustically isolated room using a Nicolet CA 2000 microcomputer. Clicks of 90; 80; 70 and 60 dBn HL were presented through earphones. The results suggest that malnutrition leads to an increase in wave I latencies in patients with marasmus, and in waves I, III and V in those with kwashiorkor or marasmic-kwashiorkor type at 90 dB HL. At discharge, all but one patient with kwashiorkor showed reduced latencies of waves I, III and V compared to the values on admission. Despite the small sample, these preliminary results pointed out that the process of sensory stimulation used in our study in a properly directed, systematic and individualized manner showed encouraging results in terms of AEP recovery in these children.

Objectives Decreased blood hemoglobin (HbB) levels and anemia have been associated with abnormal brainstem auditory evoked responses (BAER). Lead (Pb) exposure has also been associated with anemia and aberrant BAER. This study investigated the relationship between HbB level and BAER wave latency and amplitude in Pb-exposed Andean children. Design and methods Sixty-six children aged 2 to 15 years (mean age: 9.1; SD: 3.3) living in Pb-contaminated villages were screened for HbB levels, blood Pb (PbB) levels and BAER latencies and amplitudes. Results The mean HbB level observed in the study group was 11.9 g/dL (SD: 1.4; range: 8.6–14.8 g/dL). The mean HbB level corrected for altitude was 10.3 g/dL (SD: 1.4; range: 6.9–13.1 g/dL), and suggestive of anemia. The mean PbB level was 49.3 μg/dL (SD: 30.1; range: 4.4–119.1 μg/dL) and indicative of Pb poisoning. Spearman Rho correlation analyses revealed significant associations between the BAER absolute latencies and HbB level, indicating that as the HbB level decreased, the BAER wave latency increased. Children with low HbB levels (≤11 g/dL) showed significantly prolonged absolute latencies of waves I, II, III, IV and V compared to the children with normal HbB levels. Although a significant relationship between HbB and BAER waves was observed, no significant associations between PbB level and BAER parameters were found. Conclusion Low hemoglobin levels may diminish auditory sensory-neural function, and is therefore an important variable to consider when assessing BAER in children with anemia and/or Pb exposure.
