Objective: To describe the initial experience and demographics of T2* cardiac magnetic resonance-based myocardial-iron quantification of transfusion-dependent thalassemia-major (TM) patients from Pakistan and the correlation with serum ferritin., Methods: Eligible TM patients presenting between April 2014 and April 2015 to Aga Khan University Hospital, Pakistan, for T2*CMR were included. The severity of myocardial-iron deposition was defined as follows: normal T2*>20 ms, mild-moderate T2*10 to 20 ms, and severe T2*<10 ms. Cardiac symptoms were classified using the NYHA functional classification. Echocardiographic systolic and diastolic functions were performed. Continuous variables were presented as the median (minimum-maximum value). Correlation was measured using the Spearman rank correlation. Multivariate logistic regression was used to determine factors associated with the NYHA functional class., Results: A total of 83 patients (49 male and 34 female) with TM, age 19 (5 to 45) years at presentation for T2*CMR, were reviewed. At presentation, 70% of the patients were classified as NYHA class II or worse. T2*<20 ms was observed in 62.6% of the patients, with 47% showing severe iron deposition (T2<10 ms). No correlation of T2*<20 ms (r=-0.157, P=0.302) and T2*<10 ms (r=-0.128, P=0.464) was observed with serum ferritin. On multivariate analysis, lower T2* values correlated with a worsening NYHA functional class., Conclusions: There is a high prevalence of severe myocardial iron load in Pakistani TM patients. Serum ferritin did not correlate with T2* values. Lower T2* was the only clinical factor associated with the NYHA functional class.

We describe an unusual presentation of factor XIII (FXIII) deficiency in a 17-year-old boy who was diagnosed with this congenital deficiency at the age of 18 months. He had a history of spontaneous splenic rupture 8 years ago, which was managed conservatively. He now presented with sudden severe abdominal and left shoulder pain for 1 day, with no history of antecedent trauma. He was in shock, and examination revealed diffuse peritonitis. A computed tomography scan showed a grade IV splenic laceration. He was taken as an emergency to the operating room where he was found to have a shattered spleen, and a splenectomy was performed. He received cryoprecipitate transfusions perioperatively. After an uneventful recovery, the patient was discharged. To the best of our knowledge, this is the first described case of a recurrent splenic rupture in a patient with FXIII deficiency.
