Omega 3 fatty acids - Potential modulators for oxidative stress and inflammation in the management of sickle cell disease

Abstract Objective Sickle cell disease is characterized by clinical complications resulting in vaso-occlusive crisis with prominent attributes of oxidative stress, inflammation, and pain. Inflammation is an integral part of this disease which further exacerbates the pain during a crisis. Omega-3 fatty acids are known to possess anti-inflammatory and anti-aggregatory properties and assist in diminishing the slow physiological inactivation. Methods A pilot nutritional interventional study was conducted wherein forty-three children with sickle cell disease aged 5-16 years were supplemented with omega-3 fatty acids for a period of six months. Analysis of oxidative stress, as well as inflammatory parameters, was done pre and post-supplementation. Results Increased free oxygen radical transference values depicting free radical generation is enhanced in these patients along with a reduced antioxidant defense, as seen by decreased free oxygen radical defense values. Supplementation with omega-3 fatty acids for a period of six months significantly reduced the inflammatory marker homocysteine in all patients, whereas high sensitive C reactive protein was significantly reduced only in females of the age group 11-16years. Simultaneously a significant reduction in oxidative stress parameters with a concomitant increase of antioxidant defense was observed in all patients. Conclusion The authors' findings suggest the regulatory effects of omega-3 fatty acids as cellular activators in alleviating the complications due to sickle cell disease. Omega-3 fatty acids hold promise as future therapeutic candidates in patients with sickle cell disease.

Bilateral orbital cellulitis in an infant: An unusual case

Bilateral orbital cellulitis is an uncommon presentation in infants, and its association with rhinosinusitis has been scantily reported in the literature. An infant underwent bilateral uncinectomy and right ethmoidal decompression for bilateral orbital cellulitis with right ethmoidal sinusitis, after a period of non-recovery with conservative treatment. Mixed infection with Escherichia coli and methicillin-sensitive Staphylococcus aureus was observed. The right eyelid swelling began to resolve; however, the left lower eyelid showed an increase in the fluctuant swelling. Transconjunctival incision and drainage of pus was done in the left eye subsequently. The patient showed marked clinical recovery and is doing well. A multidisciplinary management approach can avert potentially life-threatening sequelae of this condition.
