Methods: A prospective observational study including 223 patients receiving the branded medicine Exjade® and 101 patients receiving the copy Osveral® was carried out. Data were assessed for a 1-year period and included clinical symptoms, serum ferritin (SF), serum creatinine (SC), and alanine aminotransferase (ALT). Data were analyzed with SPSS version 22 software (SPSS, Chicago, IL, USA).
Results: The median age of the sample was 8 years. There was no significant difference in gender distribution between the two groups (p = 0.625). Nausea was the most frequently reported adverse effect followed by diarrhea and abdominal pain in both groups. Patients receiving Exjade® had a higher relative reduction of SF at the end of the study compared with the Osveral® group (19.9% versus 9.93%, p = 0.028). SC was found to be significantly higher in the Osveral® group than in the Exjade® group throughout the study period. The mean platelet count was higher in the Exjade® group. ALT was significantly higher among patients receiving Osveral® over the last three months of the study.
Conclusions: Exjade® showed a better ability to reduce SF, with less liver toxicity, and better hemostasis profile. No congenital anomalies associated with short-term use of both drugs during pregnancy were observed or reported.
Methods: Thirty Sprague-Dawley rats were randomly assigned to control (non-diabetic), PDN and non-PDN groups (n = 10). The rats were induced with diabetes by streptozotocin injection (60 mg/kg). Tactile allodynia and thermal hyperalgesia were assessed on day 0, 14 (week 2) and 21 (week 3) in the rats. The rats were sacrificed and the spinal cord tissue was collected for the measurement of oxidative stress (malondialdehyde (MDA), superoxide dismutase (SOD) and catalase) and pro-inflammatory markers (interleukin-1β (IL-1β) and tumour necrosis factor-α (TNF-α)).
Results: PDN rats demonstrated a marked tactile allodynia with no thermal hyperalgesia whilst non-PDN rats exhibited a prominent hypo-responsiveness towards non-noxious stimuli and hypoalgesia towards thermal input. The MDA level and pro-inflammatory TNF-α was significantly increased in PDN rats whilst catalase was reduced in these rats. Meanwhile, non-PDN rats demonstrated reduced SOD enzyme activity and TNF-α level and increased MDA and catalase activity.
Conclusion: The changes in oxidative stress parameters and pro-inflammatory factors may contribute to the changes in behavioural responses in both PDN and non-PDN rats.
CASE PRESENTATION: However, here we report a case of DNPE with a slightly different presentation where there is no preceding trauma and has symptoms that mimic severe pneumonia. He presented with high fever, dyspnoea and pleuritic chest pain. Despite on 10 L of oxygen supplementation via high flow mask and already given bolus intravenous antibiotic, the patient still tachypnoeic and was persistently in type I respiratory failure. His chest X-ray showed consolidative changes. Upon further investigation revealed no evidence of DVT on Doppler ultrasound and normal D-dimer level. Due to the high index of suspicion by the attending physician, PE was suspected and later confirmed with computed tomography pulmonary angiography scan. He was successfully treated with anticoagulation therapy. The objective of this case report is to share the difficult experience of diagnosing PE when the presentation highly atypical and mimics severe pneumonia.
CONCLUSION: And with such a masquerading presentation, one can easily miss the diagnosis. To the best of our knowledge, there are very few similar cases reported.
