High Frequency of Symptomatic Zinc Deficiency in Infants in Northern Ethiopia

The study conducted at the Italian Dermatological Center of Ayder Hospital in Mekelle, Northern Ethiopia, from 2008 to 2011, reported a high frequency of transient neonatal zinc deficiency (TNZD) in 18 breast-fed infants aged 4 to 20 months. These infants exhibited symptoms such as symmetrical, erythematous skin lesions, and some had ulcerations or erosions. Despite the absence of severe malnutrition or growth retardation, the condition was effectively treated with oral zinc supplements, leading to rapid improvement. The study underscored the need for increased awareness and accurate diagnosis of TNZD in Ethiopia, where it was often misdiagnosed, and suggested that low zinc levels in maternal milk might be a contributing factor. Further research was recommended to explore the causes and potential gender prevalence of TNZD in this population.
