Putative Role of Cardio Metabolic Risk Among Poorly Controlled Asthmatics in South Indian Population.

Mortality and morbidity attributed to asthma remains to be the biggest nightmare worldwide. Hence, the study was aimed to compare the cardio metabolic risk factors as assessed by Body mass index (BMI), waist hip ratio (WHR), serum triacylglycerol and uric acid in well controlled and poorly controlled asthmatics and to correlate these parameters with the severity of asthma. A case control study was conducted on 90 subjects who were segregated into well controlled asthmatics (n = 30) and poorly controlled asthmatics (n = 30) who were diagnosed based on Global initiative for Asthma management guidelines and healthy volunteers (n = 30). Centrifuged fasting venous blood samples were used for biochemical analysis, pulmonary function test, BMI, and waist hip ratio (WHR) were measured. The statistical analysis was done using SPSS version 17. There was a significant increase in BMI, WHR, lipid profile, serum uric acid and decrease in forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC in poorly controlled asthmatics. There was a significant association between FEV1 and serum uric acid, BMI and Triacylgycerol in poorly controlled asthmatics. Poorly controlled asthmatics have greater risk of developing cardiometabolic problems. Serum uric acid can be used as one of the severity markers in asthma to assess cardio metabolic risk.

Effects of vitamin D and calcium supplementation on side effects profile in patients of breast cancer treated with letrozole.

BACKGROUND: Vitamin D deficiency (<10ng/mL) and insufficiency (10-30ng/mL) may contribute to musculoskeletal symptoms observed in patients taking letrozole. This study was undertaken to assess the vitamin D status in breast cancer patients who received letrozole for >2months and to see the effects of vitamin D3 and calcium supplementation on them. METHODS: Eighty-two breast cancer patients were included. Baseline serum 25-hydroxy vitamin D concentrations were assayed and standard questionnaire was completed. They were given vitamin D3 and calcium supplementation (2000IU/1000 mg and 4000IU/1000mg) based on their baseline serum 25-hydroxy vitamin D concentration for 12weeks. RESULTS: Baseline serum 25-hydroxy vitamin D concentrations showed that 13.4% of patients were deficient and 73.2% of patients were insufficient in 25-hydroxy vitamin D. There was an increase in the concentrations of calcium, phosphorus and decrease in the concentrations of parathyroid hormone, alkaline phosphatase as the concentration of serum 25-hydroxy vitamin D increases. Patients who received letrozole for a longer duration had a low concentration of serum 25 (OH) vitamin D. Vitamin D3 and calcium supplementation increased the concentrations of calcium, phosphorous and decreased the concentrations of parathyroid hormone and alkaline phosphatase. Patients who had low serum 25-hydroxy vitamin D concentrations had more musculoskeletal symptoms which was improved following supplementation (9.14 vs 8.10 p=0.000). CONCLUSION: Vitamin D3 supplementation significantly improved serum 25-hydroxy vitamin D concentrations and decreased letrozole-induced arthralgia.
