“…This is because the different patterns of sun exposure of the included subjects [21] as well as the genetic and ethnic variations [22] might all influence the iron status and thereby the serum ferritin levels. Nevertheless, we cannot exclude the concept of serum ferritin being unrelated to hair loss, taking into consideration the reported prevalence of a low serum ferritin level in some populations [23,24]. …”

Aim: Evaluation of serum ferritin and vitamin D levels in females with chronic telogen effluvium (TE) or female pattern hair loss (FPHL), in order to validate their role in these common hair loss diseases. Methods: Eighty females (18 to 45 years old) with hair loss, in the form of TE or FPHL, and 40 age-matched females with no hair loss were included in the study. Diagnosis was based upon clinical examination as well as trichogram and dermoscopy. Serum ferritin and vitamin D₂ levels were determined for each participant. Results: Serum ferritin levels in the TE (14.7 ± 22.1 μg/l) and FPHL (23.9 ± 38.5 μg/l) candidates were significantly lower than in controls (43.5 ± 20.4 μg/l). Serum vitamin D₂ levels in females with TE (28.8 ± 10.5 nmol/l) and FPHL (29.1 ± 8.5 nmol/l) were significantly lower than in controls (118.2 ± 68.1 nmol/l; p < 0.001). These levels decreased with increased disease severity. Serum ferritin cut-off values for TE and FPHL were 27.5 and 29.4 μg/l, respectively, and those for vitamin D were 40.9 and 67.9 nmol/l. Conclusion: Low serum ferritin and vitamin D₂ are associated with hair loss in females with TE and FPHL. Screening to establish these levels in cases of hair loss and supplementing with them when they are deficient may be beneficial in the treatment of disease.

“…In Mexico City, the prevalence of iron deficiency in children 5–11 years old was 4.5%, with a 95% confidence interval (95% CI) between 2.3 and 8.6, and 11% (95% CI: 7.4 – 14.5) in adolescents 12–14 years old [11]. The prevalence of anemia according to the 2012 National Health and Nutrition Survey in Mexico was 10.1% (95% CI: 9.3 – 10.9) in children 5–11 years old [12].…”

BackgroundIron deficiency is one of the most common nutritional deficiencies worldwide. It is more prevalent when iron requirements are increased during pregnancy and during growth spurts of infancy and adolescence. The last stage in the process of iron depletion is characterized by a decrease in hemoglobin concentration, resulting in iron deficiency anemia. Iron deficiency, even before it is clinically identified as anemia, compromises the immune response, physical capacity for work, and intellectual functions such as attention level. Therefore, interventions addressing iron deficiency should be based on prevention rather than on treatment of anemia. The aim of this study was to compare short- and medium-term effects on ferritin concentration of daily supplementation with ferrous sulfate or iron bis-glycinate chelate in schoolchildren with iron deficiency but without anemia.MethodsTwo hundred schoolchildren from public boarding schools in Mexico City who had low iron stores as assessed by serum ferritin concentration but without anemia were randomly assigned to a daily supplement of 30 mg/day of elemental iron as ferrous sulfate or iron bis-glycinate chelate for 12 weeks. Iron status was evaluated at baseline, one week post-supplementation (short term), and 6 months (medium term) after supplementation.ResultsFerritin concentration increased significantly between baseline and post-supplementation as well as between baseline and 6 months after supplementation. One week post-supplementation no difference was found in ferritin concentration between iron compounds, but 6 months after supplementation ferritin concentration was higher in the group that received bis-glycinate chelate iron. However, there is no difference in the odds for low iron storage between 6 months after supplementation versus the odds after supplementation; nor were these odds different by type of supplement. Hemoglobin concentration did not change significantly in either group after supplementation.ConclusionsSupplementing with 30 mg/d of elementary iron, either as ferrous sulfate or iron bis-glycinate chelate for 90 days, showed positive effects on increasing ferritin concentration in schoolchildren with low iron stores, and this effect persisted 6 months after supplementation.

Giriş ve Amaç:Demir eksikliği anemisi gelişmekte olan ülkelerde önemli bir sorun teşkil etmektedir. Demir eksikliği anemisi tespit edilen çocukların ve ailelerinin demografik özelliklerini, serum çinko düzeyi ile karşılaştırmayı amaçladık. Yöntem ve Gereçler: Haydarpaşa Numune Eğitim ve Araştırma Hastanesi Çocuk Sağlığı ve Hastalıkları Polikliniği'nde 01.11.2013-01.12.2013 tarihleri arasında 6 ay-12 yaş arasındaki demir eksikliği anemisi olan çocukların boy ve ağırlık persentillerine bakılarak, beslenme alışkanlığı ve ailenin gelir düzeyi sorgulanarak, serum çinko örneği için kan alındı. Hastalardan alınan kan örneklerinden çinko düzeyi saptanarak çinko düzeylerindeki farklılıkların demir eksikliği anemisi ile ilişkisi değerlendirildi. Bulgular: Demir eksikliği anemisi olan hastalardan bakılan serum çinko düzeyi ile cinsiyet, beslenme, aile gelir düzeyi, aile eğitim durumu arasında istatiksel olarak anlamlı fark bulunmadı (p>0.05). Çinko düzeyi ile yaş ve ağırlık arasında anlamlı pozitif korelasyon mevcuttu (p<0.05). Çinko düzeyi ile boy ve Fe/Febk yüzde değeri arasında anlamlı korelasyon yoktu (p>0.05). Tartışma ve Sonuç: Biz bu çalışmada demir eksikliği anemisi olan çocuklarda anlamlı bir çinko eksikliği tespit etmedik. Bunu çalışmaya alınan çocuk yaş grubu yelpazesinin geniş olmasına, özellikle büyük çocukların çinko ihtiyacını kuruyemişten ve proteinden karşılayabilmesine bağlıyoruz. Ancak konuyla ilgili daha fazla sayıda hasta içeren çalışmalara ihtiyaç vardır.
