ABSTRACT
Background: There is total alteration of various antioxidants in response to the oxidative stress, which is one of the major patho-physiologic hallmarks in chronic obstructive pulmonary disease (COPD) development. This study aims to establish the correlation between different antioxidants in normals and COPD, study the alteration in the correlation due to COPD and smoking as well as the impact of COPD and smoking on antioxidants levels.Methods: Study comprises of 96 normals as group I and 96 COPD patients as group II. The antioxidants albumin (Alb), bilirubin (Bil), uric acid (UA) ceruloplasmin (Cp), glutathione peroxidase (GSHPx), catalase (CAT) and superoxide dismutase 3 (SOD3) were estimated.Results: Significant lower serum Alb, UA, SOD3 and increased serum Cp and GSHPx were found in Group II. Significant correlation was found between Alb and UA (r=0.24); Bil and UA (r=0.26); Alb and CAT (r=0.211) and SOD3 and CAT (r=0.318) in normals. However, these correlations were altered in COPD where Alb correlates with Bil (r=0.235); UA with CAT (r=0.203) and SOD3 with GSHPx (r=-0.27). The correlation between SOD3 and CAT remained unaltered. Similar correlation of UA with Alb and Bil was observed in nonsmoker normals and between SOD3 and CAT in smoker normals. In COPD, no correlation was seen in nonsmokers, while in smokers Alb correlates with Bil (r=0.316) and SOD3 with CAT (r=0.317).Conclusions: These alterations may have clinical ramifications in further understanding the pathogenesis of COPD and developing therapeutic approaches.
ABSTRACT
Introduction: Patients of DM are known to have low levelsof serum magnesium levels as compared to non-diabetics.There is a link between the low magnesium levels and poorglycemic controls and subsequently leading to complicationsin diabetic patients. The aim of this study was to assess theserum magnesium levels in relation to glycemic status indiabetic patients as compared to non-diabetics.Material and Methods: 172 cases of previously diagnosedDM were taken along with the age and sex matched controlswho were healthy and non-diabetic and their blood sampleswere analyzed for magnesium and blood sugar fasting andpost prandial.Results: In our study we have found that there is a significanthypomagnesemia in diabetic cases as compared to nondiabetic controls which is in accordance with other studies.There also exists a negative correlation between mean serummagnesium levels (2.08 ± 0.4 mg/dL) and mean fastingplasma sugar (FBS) (159.72 ± 71.60 mg/dL) and mean postprandial sugar (PPS) (222.76 ± 100.86 mg/dL) levels. Nosignificant variation as per age and sex in serum magnesiumlevels amongst diabetic subjects have been found in our study.Conclusion: Hypomagnesemia is common in diabetics ashas been found in our study also, and it helps in regulationof glycemic levels and in turn also affects magnesium levels.Considering estimation of magnesium as a routine laboratorywork up protocol in the management of diabetes may preventvarious complications due to hypomagnesemia with earlytherapeutic intervention.
ABSTRACT
A 42-year-old female presented to us with a complaint of sudden painless loss of vision in both eyes of three days duration. Visual acuity was 20/100 for distance in both eyes. Fundus examination showed bilateral peripapillary hemorrhages, with subhyaloid and vitreous hemorrhage in both eyes. Hematological investigations revealed hemoglobin (HB 7 gm %) and severe thrombocytopenia (12,000/ ul). She was referred to a hematologist where a diagnosis of idiopathic thrombocytopenic purpura (ITP) was made. She was treated for systemic condition with regular ophthalmic follow-up. Over the next nine months, retinal hemorrhages completely resolved and the patient regained her visual acuity. The purpose of this case report is to highlight the clinical presentation of severe anemia, which is different from previous reports and the role of an ophthalmologist in first detecting the Idiopathic thrombocytopenic purpura (ITP), which led to successful recovery.
