Oral versus intravenous iron therapy in iron deficiency anemia: An observational study.

BACKGROUND: Intravenous (IV) iron sucrose is claimed to have better safety profile and efficacy in treatment of iron deficiency anemia than conventional oral iron supplements. AIM: The aim of the study was to compare the efficacy and safety of IV iron therapy with oral iron supplements in iron deficiency anemia. METHODS: An observational study was carried out by allocating 100 patients with baseline hemoglobin between 5 and 10 g/dL into two groups of oral iron and IV iron group. Hemoglobin and serum ferritin levels were measured at admission, on day 14 and on day 28. Adverse effect profile for each group was tabulated. Mean and standard deviation were calculated for each group and compared. RESULTS: A total of 100 patients participated consisting of 37 males and 63 females. Baseline hemoglobin and serum ferritin for both groups were comparable. After initiation of therapy, hemoglobin in oral iron group raised from 6.45 (0.72) to 8.84 (0.47) on day 14 and to 9.69 (0.47) on day 28. Hemoglobin in IV iron group increased from 6.34 (0.86) to 10.52 (0.61) on day 14 and to 11.66 (0.84) on day 28. Serum ferritin in oral iron group increased from 8.3 (1.9) to 33.8 (1.29) on day 14 and to 43.61 (8.8) on day 28. Serum ferritin in IV iron group raised from 8.23 (4.64) to 148.23 (11.86) on day 14 but decreased to 115.76 (15.3) on day 28. The data were statistically significant for IV iron therapy on day 14 and day 28. Of 100 patients, 18 patients (12 in oral and 6 in IV iron groups) had adverse effects. Among the oral iron group, metallic taste and constipation were major side effects followed by heart burn and nausea. In the IV iron group, arthralgia (4 patients of 6) was the major side effect observed. One patient (of 6) in IV group had hypotension. Anaphylaxis was not observed in any patient in either group. CONCLUSION: IV iron therapy is effective and safe for management of iron deficiency anemia.

Sickle cell disease prevents diabetes mellitus occurrence: A hospital based cross-sectional study.

BACKGROUND: Sickle cell disease is the commonest inherited hemoglobinopathy. There are few reports point towards decrease incidence of diabetes mellitus in sickle cell disease patients. MATERIALS AND METHODS: This cross-sectional study was conducted in VIMSAR, Burla, Odisha between Nov 2014 to Oct 2016. FBS and 2 hours OGTT reports of adult sickle cell disease patients were compared with the same reports from equal no of adult persons without sickle cell disease (controls) to found out any significant difference in prevalence of diabetes mellitus in sickle cell disease patients versus controls. RESULTS: A total of 137 adult patients of sickle cell disease out of which males were 94 (68.61%) and females were 43 (31.38%) with an average age of (26.7 ± 10.9) years and an equal number of controls [males 87 (63.8%) and females 50 (36.5%)] with an average age of (47.6 ± 13.6) years were included in the study. We found diabetes mellitus in 2 (1.46%) out of 137 sickle cell disease patients with an average BMI 18.5 kg/m2 versus 12 (8.76%) in equal number of controls with an average BMI of 22.6 kg/m2. CONCLUSION: This study concludes that prevalence of diabetes mellitus in sickle cell disease patients is significantly lower than non-sickle cell disease persons. This may be due to less longevity and low BMI in sickle cell disease patients.

Multifocal Tubercular Dactylitis: A Rare Presentation of Skeletal Tuberculosis in an Adult.

Tubercular dactylitis is an uncommon form of osteo-articular tuberculosis seen in children. Multifocal involvement, simultaneously involving hands and feet is extremely uncommon. Here we report an adult patient with tubercular dactylitis involving multiple digits of both hands and second digit of right foot in absence of any risk factors like immunodeficiency or any debilitating condition. The patient was successfully treated with anti-tubercular drugs for six months. Mycobacterium tuberculosis infection of bones and joints can present in an unusual way but early diagnosis and treatment caries a good prognosis.

Transcriptomic meta-analysis reveals up-regulation of gene expression functional in osteoclast differentiation in human septic shock.

Septic shock is a major medical problem with high morbidity and mortality and incompletely understood biology. Integration of multiple data sets into a single analysis framework empowers discovery of new knowledge about the condition that may have been missed by individual analysis of each of these datasets. Electronic search was performed on medical literature and gene expression databases for selection of transcriptomic studies done in circulating leukocytes from human subjects suffering from septic shock. Gene-level meta-analysis was conducted on the six selected studies to identify the genes consistently differentially expressed in septic shock. This was followed by pathway-level analysis using three different algorithms (ORA, GSEA, SPIA). The identified up-regulated pathway, Osteoclast differentiation pathway (hsa04380) was validated in two independent cohorts. Of the pathway, 25 key genes were selected that serve as an expression signature of Septic Shock.

Evaluation of Lipid Profile and Apolipoproteins in Essential Hypertensive Patients.

INTRODUCTION: Essential hypertension is one of the most common diseases of the Indian population contributing greatly to the morbidity, mortality and economic burden. It has a strong association with cardiovascular disease and abnormal lipid metabolism. Not only the traditional lipid parameters, but also the novel lipid components like Apo A1 and Apo B100 also have been identified to play a role. AIM: The present study was done to evaluate serum lipid profile and Apo A1, Apo B 100 in essential hypertensive patients and correlate their values with the degree of hypertension. MATERIALS AND METHODS: Fasting samples from 55 age and sex matched controls and 55 essential hypertensives were tested for plasma glucose, serum urea, creatinine, lipid profile, apo A1 and apo B100. The cases were subclassified based on the severity of hypertension according to JNC criteria. RESULTS: The study showed a significantly raised value for serum cholesterol, triacylglycerol, Low Density Lipoprotein (LDL), Very Low-Density Lipoprotein (VLDL) in the hypertensive patients than the control group whereas serum High-Density Lipoprotein (HDL) registered a fall in the cases. Apo A1 revealed a non-significant fall in the hypertensive patients. In contrast, there was a rise in the serum apo B100 in the cases. Apo B100/apo A1 ratio was significantly raised in both stage I and stage II hypertensive patients in comparision to the controls. When correlated, serum apo A1 revealed a negative association where as serum apo B 100 showed a positive association with systolic and diastolic bloood pressure. Both LDL/HDL and apoB100/apo A1 and apo B100 revealed a significant positive association with both SBP and DBP. However, apoB100/apo A1 revealed a more positive association in comparision to LDL/HDL ratio (r=0.749, p<0.001, r=0.756, p<0.001 vs r=0.336, p<0.000, r=0.312, p<0.001). CONCLUSION: Apo B100/apoA1 has emerged as an important complementary parameter in addition to traditional lipid ratio for evaluation of risk for future cardiovascular disease.

Non-Classical monocytes display inflammatory features: Validation in Sepsis and Systemic Lupus Erythematous.

Given the importance of monocytes in pathogenesis of infectious and other inflammatory disorders, delineating functional and phenotypic characterization of monocyte subsets has emerged as a critical requirement. Although human monocytes have been subdivided into three different populations based on surface expression of CD14 and CD16, published reports suffer from contradictions with respect to subset phenotypes and function. This has been attributed to discrepancies in reliable gating strategies for flow cytometric characterization and purification protocols contributing to significant changes in receptor expression. By using a combination of multicolour flow cytometry and a high-dimensional automated clustering algorithm to confirm robustness of gating strategy and analysis of ex-vivo activation of whole blood with LPS we demonstrate the following: a. 'Classical' monocytes are phagocytic with no inflammatory attributes, b. 'Non-classical' subtype display 'inflammatory' characteristics on activation and display properties for antigen presentation and c. 'Intermediate' subtype that constitutes a very small percentage in circulation (under physiological conditions) appear to be transitional monocytes that display both phagocytic and inflammatory function. Analysis of blood from patients with Sepsis, a pathogen driven acute inflammatory disease and Systemic Lupus Erythmatosus (SLE), a chronic inflammatory disorder validated the broad conclusions drawn in the study.

Changing bacteriological profile and mortality trends in community acquired pneumonia.

There are very few and conflicting Indian data regarding the bacteriological etiology of community acquired pneumonia (CAP). Adding to this agony, there is no credible data from the eastern part of India. This is a cross-sectional study and descriptive in nature over a period of 1-year. Of the 464 cases of the study population, we could isolate aerobic bacteria in 149 patients (32.1%). Streptococcus pneumoniae has been identified as the most common organism causing CAP (68/149). Gram-negative bacilli (GNB) as a group exceeded marginally over S. pneumoniae (69/149). Among GNB, Pseudomonas aeruginosa was the most common organism (31/69), followed by Klebsiella pneumoniae (29/69). Staphylococcus aureus was identified in (12/149) cases. Co-amoxyclav is still the most sensitive drug for S. pneumoniae. P. aeruginosa was most sensitive to imipenam followed by piperacillin-tazobactam.

Decreased prevalence of sepsis but not mild or severe P. falciparum malaria is associated with pre-existing filarial infection.

BACKGROUND: Enhanced inflammatory host responses have been attributed as the cellular basis for development of severe malaria as well as sepsis. In contrast to this, filarial infections have been consistently reported to be associated with an immunological hypo-responsive phenotype. This suggests that successful control of filariasis by employing mass drug administration, could potentially contribute to an increase in incidence of sepsis and cerebral malaria in human communities. A case control study was undertaken to address this critical and urgent issue. METHODS: Eighty-nine patients with sepsis and one hundred and ninety-six patients with P. falciparum malaria all originating from Odisha, were tested for prevalence of circulating filarial antigens - a quantitative marker of active filarial infection. Antibodies to four stage specific malarial recombinant proteins were measured by solid phase immunoassays and circulating CD4+CD25high T-cells were quantified by flow cytometry with an objective to study if pre-existing filarial infections influence antibody responses to malarial antigens or the levels of circulating T-regulatory cells in P. falciparum infected patients. RESULTS: Prevalence of filarial antigenemia was significantly less in sepsis patients as compared to controls suggesting that pre-existing filariasis could influence development of sepsis. On the other hand, levels of circulating filarial antigen were comparable in severe malaria cases and healthy controls suggesting that development of severe malaria is independent of pre-existing W. bancrofti infections. Plasma TNF-a, RANTES and antibodies to recombinant malarial proteins as well as levels of circulating CD4+ CD25high cells were comparable in malaria patients with or without filarial infections. CONCLUSIONS: These observations imply that successful control of filariasis could have adverse consequences on public health by increasing the incidence of sepsis, while the incidence of severe malaria may not adversely increase as a consequence of elimination of filariasis.
