Blood biochemistry has significant effect on pathophysiology of human body. Recently few studies found the association of biochemical abnormalities in sickle cell patients. Sickle cell disease showed clinical variability where African ancestors have severe phenotype than Indian sicklers. Our aim was to evaluate the biochemicals in sickle cell patients and their effect on severity. Here we present the comparative biochemical levels in sickle cell patients as well as controls. Sickle cell patients diagnosed by HPLC and biochemical analysis done by Beckman-auto analyzer. T test applied for statistical analysis. Result showed the renal abnormality lesser in patients and related biochemical within the normal range and statistically not significant. Electrolytes, hepatic enzymes, alkaline phosphatase and glucose were elevated and statistically significant (P value \0.05). Observation of the study concludes the biochemical abnormality play a significant role in sickle cell patient's physiopathology and can be used to management of the disease.

BackgroundSome reports have shown that co-inheritance of α-thalassemia and sickle cell disease improves hematological parameters and results in a relatively mild clinical picture for patients; however, the exact molecular basis and clinical significance of the interaction between α-thalassemia and sickle cell disease in India has not yet been described. There is little agreement on the clinical effects of α-thalassemia on the phenotype of sickle cell disease.MethodsComplete blood count and red cell indices were measured by an automated cell analyzer. Quantitative assessment of hemoglobin variants HbF, HbA, HbA2, and HbS was performed by high performance liquid chromatography (HPLC). DNA extraction was performed using the phenol-chloroform method, and molecular study for common α-deletions was done by gap-PCR.ResultsOut of 60 sickle cell anemia patients, the α-thalassemia genotype was found in 18 patients. Three patients had the triplicated α-genotype (Anti α-3.7 kb), and the remaining patients did not have α-deletions. This study indicates that patients with co-existing α-thalassemia and sickle cell disease had a mild phenotype, significantly improved hematological parameters, and fewer blood transfusions than the patients with sickle cell anemia without co-existing α-deletions.ConclusionCo-existence of α-thalassemia and sickle cell anemia has significant effects on the phenotype of Indian sickle cell patients.

With an aim to study the mechanism of adaptation to acute hypoxic periods by hypoxia-tolerant catfish, Clarias batrachus, the mass-specific metabolic rate (VO2) along with its hematological parameters, metabolic response and antioxidant enzyme activities were studied. During progressive hypoxia, C. batrachus was found to be an oxyconformer and showed a steady decline in its aquatic oxygen consumption rate. When C. batrachus was exposed for different periods at experimental hypoxia level (0.98 +/- 0.1 mg/L, DO), hemoglobin and hematocrit concentrations were increased, along with decrease in mean cellular hemoglobin concentration, which reflected a physiological adaptation to enhance oxygen transport capacity. Significant increase in serum glucose and lactate concentration as well as lactate dehydrogenase activity was observed. Antioxidant enzymes were found to operate independently of one another, while total glutathione concentration was unaffected in any of the tissues across treatments. These observations suggested that hypoxia resulted in the development of oxidative stress and C. batrachus was able to respond through increase in the oxygen carrying capacity, metabolic depression and efficient antioxidant defense system to survive periods of acute hypoxia.
