Aim: Reactive thrombocytosis can result from various mechanisms, including increased megakaryocyte activity and reduced platelet clearance. Iron deficiency, often linked to elevated platelet production, is a common cause. However, the role of zinc deficiency in platelet count changes remains unclear. This study retrospectively investigated the effects of iron and zinc deficiencies on platelet parameters in children.
Material and Methods: 73 pediatric patients (36 females, 37 males) were analyzed for platelet count and mean platelet volume (MPV) in relation to ferritin and zinc levels. Patients were grouped as follows: Group 1- normal ferritin and zinc; Group 2- low ferritin, high zinc; Group 3- normal ferritin, low zinc; Group 4- low ferritin and zinc. Statistical analysis included assessment of normality using the Shapiro-Wilk and Kolmogorov-Smirnov tests, followed by one-way ANOVA and post-hoc pairwise t-tests with Bonferroni correction for multiple comparisons, and Pearson correlation analysis for MPV and platelet count relationships.
Results: Platelet counts and MPV were similar across all groups, indicating no direct effect of zinc deficiency on thrombocytosis. Zinc-deficient patients had significantly lower ferritin levels (p < 0.05). A moderate inverse correlation was observed between MPV and platelet count (r = -0.548), which became stronger with MPV stratification (r = -0.841).
Conclusion: Zinc deficiency was not associated with elevated platelet counts in this cohort. However, its association with reduced ferritin and the observed MPV-platelet relationship highlight the potential influence of trace elements on hematopoiesis. Clinicians should consider nutritional status in the evaluation of pediatric platelet disorders, and further research is warranted to clarify these interactions.

Pediatrik yaş grubunda demir ve çinko eksiklikleri ile trombositoz arasındaki ilişkinin ortaya konması

Öz

Amaç: Reaktif trombositoz, artmış megakaryosit aktivitesi veya azalmış trombosit yıkımı sonucu gelişebilir. Demir eksikliği, artmış trombosit üretimi ile sıkça ilişkilendirilirken, çinko eksikliğinin trombosit parametreleri üzerindeki etkisi belirsizdir. Bu çalışmada çocuklarda demir ve çinko eksikliklerinin trombosit indeksleri üzerindeki etkileri retrospektif olarak değerlendirildi.
Gereç ve Yöntemler: 36 kız, 37 erkek olmak üzere toplam 73 pediatrik hastada ferritin ve çinko düzeyleri ile ilişkili trombosit sayısı ve ortalama trombosit hacmi (MPV) incelendi. Hastalar şu şekilde gruplandırıldı: Grup 1—normal ferritin ve çinko; Grup 2—düşük ferritin, normal çinko; Grup 3—normal ferritin, düşük çinko; Grup 4—düşük ferritin ve çinko İstatistiksel analizlerde, verilerin normal dağılımını değerlendirmek için Shapiro-Wilk ve Kolmogorov-Smirnov testlerini, ardından gruplar arası karşılaştırmalar için tek yönlü ANOVA ve çoklu karşılaştırmalar için Bonferroni düzeltmeli post-hoc pairwise t-testleri ve MPV ile trombosit sayısı ilişkisi için Pearson korelasyon analizi kullanıldı.
Bulgular: Trombosit sayısı ve MPV tüm gruplar arasında benzer bulundu ve çinko eksikliğinin doğrudan trombositoza etkisi saptanmadı. Çinko eksikliği olan hastalarda ferritin düzeyleri anlamlı olarak daha düşüktü (p < 0,05). MPV ile trombosit sayısı arasında orta düzeyde negatif korelasyon gözlendi (r = -0,548), MPV stratifikasyonu ile bu ilişki güçlendi (r = -0,841).
Sonuçlar: Çinko eksikliği bu çalışmada trombosit sayısında artışla ilişkili bulunmadı. Ancak ferritin düşüklüğü ile ilişkisi ve MPV-trombosit sayısı korelasyonu, iz elementlerin hematopoez üzerinde potansiyel etkilerini göstermektedir. Klinik olarak, çocuklarda trombosit parametrelerini değerlendirirken beslenme durumu göz önünde bulundurulmalıdır ve bu etkileşimlerin netleştirilmesi için ileri araştırmalara ihtiyaç vardır.
