RESUMEN
Introduction: Statins are known to have anticoagulation and anti-inflammatory effects. This study aimed to investigate the effect of Rosuvastatin in reduction of post thrombotic syndrome (PTS) following deep vein thrombosis (DVT). Methods: In this randomized clinical trial, patients who were diagnosed with DVT of lower extremity were randomly assigned to 4 treatment groups: group 1: Warfarin, group 2: Warfarin + Rosuvastatin, group 3: Rivaroxaban, and group 4: Rivaroxaban + Rosuvastatin. The treatments were followed for 3 months and prevalence of PTS (as primary outcome), as well as the changes in serum levels of D-dimer and C reactive protein (CRP), and the extent of thrombosis before and after the intervention (as secondary outcomes) were compared between groups. Results: 182 patients with the mean age of 55.22 ± 4.1 years finished the trial period (51.64% male). There was no significant difference between the groups regarding the baseline characteristics. Based on the Brandjes score, 31 (17.03%) patients had PTS at the end of the study. The occurrence of PTS was significantly lower in the groups taking statins (p<0.0001). Although the change in the mean difference of legs circumference before and after intervention, were significant in all groups (p < 0.05), the differences was more prominent in groups 2 and 4 (p < 0.0001). After 3 months of taking medication, decrease of CRP was more prominent in the statin groups (p = 0.001), and most cases with normal CRP were in statin groups. Among the patients with the serum D-dimer level above 10000 ng/mL, patients in the statin groups experienced significantly more reduction in D-dimer levels than the other groups (p<0.001). Conclusion: Rosuvastatin administration in combination with rivaroxaban or warfarin significantly reduces the level of inflammatory factors including CRP and D-dimer, compared to patients receiving anticoagulants alone. Rosuvastatin administration can significantly reduce the incidence of PTS and cause a difference in the size of the lower limbs within 3 months.
RESUMEN
OBJECTIVES: Thalassemia major (TM) is one of the most common blood disorders with a high mortality rate due to cardiovascular disease. Vitamin D deficiency has been suggested to implicate in cardiac abnormalities. In this prospective study, we aimed to investigate the relationship between serum levels of vitamin D and tissue Doppler (TD) echocardiographic indices in thalassemia major patients. METHODS: A total of 81 TM patients, including 56 females and 25 males, with a mean age of 27.5± 6.8 years, were enrolled consecutively. Serum levels of vitamin D and other biomedical parameters were measured. Then, all patients were subjected to TD echocardiography. Correlations between the serum parameters and systolic and diastolic indices were examined. RESULTS: The serum level of vitamin D was correlated with systolic and diastolic indices such as the EF (r= 0.33, P= 0.003) and TD Imaging (TDI)-lateral (r= 0.31, P= 0.005). However, no correlations were observed between vitamin D deficiency and the LV septal and posterior wall thickness, TDIseptal, tricuspid regurgitation peak gradient (TRPG), pulmonary artery systolic pressure (PASP), deceleration time (DT), and propagation velocity (PVcm/s) indices. The results revealed also no linear correlations between serum vitamin D and albumin (r= -0.17, P= 0.06), ALP (r= -0.12, P= 0.14), T4 (r= -0.11, P= 0.16), as well as TSH (r= -0.10, P= 0.19). CONCLUSION: It seems that vitamin D deficiency in patients with TM is associated with systolic but not diastolic dysfunctions, possibly as consequences of related biochemical abnormalities.
