β-thalassemia is the most common genetic disorder worldwide with an increased prevalence around the Mediterranean, Indian subcontinent and in South-East Asia. Various siderotic and non-siderotic complications significantly impact the quality of life. Thalassemic patients are also at risk of zinc deficiency due to diverse causes including desferrioxamine chelation. This study sought to investigate the prevalence of zinc deficiency in beta thalassemia major patients on desferrioxamine for iron chelation. Study design: This was a descriptive, prospective, cross-sectional study over a 6-month period. 63 cases of beta thalassemia major within the age group of 5-15 years on desferrioxamine for at least 1 year, were included. Basic patient demographics such as age, gender and duration of disease were recorded. Serum zinc levels were determined by atomic absorption spectrophotometry. Results: The mean age of patients was 10.84±3.47 (5 to 15) years. There were 35 (55.6%) males and 28(44.4%) females. The prevalence of zinc deficiency (zinc levels < 50 μg / dl) was 22.2%. Proportions of deficiency were higher in males with a duration of disease beyond 10 years. Conclusions: Zinc deficiency is not uncommon in beta thalassemia patients on desferrioxamine. We suggest that zinc levels be regularly monitored in these patients.

Background: The effect of Helicobacter-pylori eradication therapy on the platelet counts in patients with immune thrombocytopenia is still debatable. The aim of this study was to assess the response rates of standard triple eradication therapy in secondary immune thrombocytopenia with Helicobacter pylori infection. Methods: From January 2012 to December 2013, 197 patients were diagnosed to have immune thrombocytopenia, out of which 22(11.1%) patients infected with HelicobacterPylorus were enrolled in this study. Helicobacter-Pylori infection was documented by Helicobacter-pylori stool antigen enzyme immunoassay method. All positive patients were put on triple eradication therapy. The responses rates to treatment were defined as per International Working Group on ITP. Results: Mean age of patients was 43.18±12.5 years. There were 10(45.5%) males and 12 (54.5%) females. Of the 22 patients, 7(31.8%) exhibited a complete response (CR) to Hpylori eradication therapy; 10(45.4%) attained a response; and 5(22.7%) had no response. Mean base line platelet counts were 53.36±24.5x109 /l, while platelet counts at 4 week following eradication was 80.86±51.0x109 /l (P=0.003). The predictive factor of response following eradication therapy was baseline platelet counts. Virtually all responders had baseline platelet counts >30x109 /l and all non-responders had <30x109 /l of platelet counts. Conclusions: Though the prevalence of H-pylori is low, this study confirmed the efficacy of eradication in increasing the platelet counts in H-pylori positive patients with ITP. It is an important measure in short time, safe and very cost effective to achieve platelets increment. We endorse the routine detection and eradication treatment of H-pylori infective ITP patients.
