Evaluation of serum transferrin receptor and sTfR ferritin indices in diagnosing and differentiating iron deficiency anemia from anemia of chronic disease.

Objective. The present study was conducted to assess the utility of serum transferrin receptor (sTfR) and sTfR ferritin indices to differentiate ACD from IDA and also to diagnose coexisting IDA and ACD. Methods. The study group comprised of 30 IDA patients, 30 cases of ACD and 30 age and sex matched controls. Complete hemogram with peripheral smear examination, markers of ACD, iron profile including serum ferritin and serum transferrin receptor levels were done in all patients and controls. Serum TfR and ferritin indices were calculated. Results. sTfR levels were significantly higher in the IDA group compared to ACD group (p<0.001). ACD group was further subdivided into two groups on the basis of sTfR levels (B1<3 μg/ml and B2 ≥ μg/ml), suggesting coexisting IDA in group B2. sTfR/log ferritin index was > 1.5 in all cases of IDA and ACD with coexisting IDA while all pure ACD cases and control subjects had sTfR/log ferritin index < 1.5. All case in IDA group had log sTfR/serum ferritin index > 2.55 and all patients with ACD with or without associated iron deficiency had log sTfR/serum ferritin ratio < 2.55. Conclusion. The sTfR levels along with the above mentioned indices can be very useful in differentiating pure IDA, ACD and ACD with coexisting iron deficiency, thus providing a noninvasive alternative to bone marrow iron.

Etiological profile of stroke and its relation with prothrombotic states.

OBJECTIVE: To study the etiological profile of childhood stroke and its relation with prothrombotic states. METHODS: Children with acute stroke with no evidence of CNS infection or head injury were studied. Stroke was confirmed by CT scan and further evaluated by MRI. Cardiac status was assessed with transthoracic echocardiography. Test for hypercoagulable state (antithrombin III, protein C, protein S, anticardiolipin antibody IgG and IgM and lupus anticoagulant) were done in all patients. RESULTS: A total of 66 children were enrolled--36 cases and 30 controls. Presenting symptoms were motor deficit (72%), seizure (66%), altered sensorium (36%), aphasia (27%). Causes identified were antiphospholipid antibody syndrome (25%), Moya Moya disease (16.6%), cardiac disease (11.1%), vasculitis (5.5%), ATIII deficiency (5.5%), Protein C deficiency (2.7%). Etiology remained unknown in 25% of cases with infarction. Hemorrhage was seen in 8.2% of cases and they had DIC or liver disease as the underlying cause. CONCLUSIONS: Magnetic Resonance Angiography and ELISA for antiphospholipid antibody should be done in all patients with stroke without an obvious cause.

Antithymocyte globulin and cyclosporin in children with acquired aplastic anemia.

OBJECTIVE: To assess the responses to ATG and cyclosporin combination in patients of aplastic anemia. METHODS: Twenty three (17M: 6F) patients of aplastic anemia (11 very severe aplastic anemia (VSAA) and 12 severe aplastic anemia (SAA), were administered antithymocyte globulin and cyclosporin. RESULTS: The median age of patents was 8 years (range 6-12 years). Three patients died within 2 months of therapy. Twenty children (11 SAA and 9 VSAA) were finally analysed. Six months after the start of treatment, 8/20 (40%) patients responded-2 complete (CR) and 6 partial responses (PR). At the end of 1 year; 2 patients maintained CR and seven patients continued PR (overall responders 45%). The response was better in SAA (54.5%) with 2 CR and 4 PR; than in VSAA (33%) with 3 PR . Eleven (55%) children were alive without response. One patient developed AML 13 months later. CONCLUSION: We conclude that antithymocyte globulin and cyclosporin combination is an effective treatment for aplastic anemia patients who are ineligible for bone marrow transplantation.

Hemophagocytic syndrome associated with visceral leishmaniasis.

The present paper reports a case of 6-year-old male child, suffering from pallor, fever and hepatosplenomegaly. A clinical diagnosis of enteric fever with a second possibility of malaria was considered. Laboratory findings included bicytopenia, hyperbilirubinemia and raised liver enzymes. Bone marrow examination revealed active hemophagocytosis. On extensive search few amastigote forms of Leishmania donovani were seen. Patient was negative for other viral, bacterial and malaria infections. The final diagnosis of hemophagocytic syndrome associated with visceral leishmaniasis was made. There was response of anti-Leishmanial treatment with improvement in clinical condition.

A Study of Clinical Profile and Spontaneous Course of Eosinophilia

Aim of the study was evaluation of symptoms and signs in patients with eosinophilia, to try to find its etiology and to study the natural course of eosinophilia during the period of study. Fifty patients with absolute eosinophil count (AEC) more than 350/mm3 or differential count more than 3% irrespective of their age, sex and medical condition were included. The patients were divided into mild (AEC-350 to 1500), moderate (1500 to 5000) and severe (>5000/mm3 of blood) eosinophilia. They underwent a series of routine and special hematological and biochemical investigations including bone marrow aspiration, serum IgE estimation, and pulmonary function tests. The patients were studied for a period of 3 months. Most of the patients (52%) fell in the category of mild eosinophilia. Minimum AEC at the entry of patients into the study was 600 and maximum was 22500. Commonest presenting symptoms were anorexia (40%), pain abdomen (38%), fever (32%), and breathlessness (30%). Etiology of eosinophilia was undiagnosed in 70% of the patients. Parasitism was more common than allergic rhinitis and bronchial asthma. On follow up investigations, eosinophilia resolved on its own even without specific antieosinophilic treatment. Extensive work up of patients was not associated with significant change in the management of any patients with eosinophilia. The etiology of eosinophilia remains unrevealed in majority of the patients. Extensive work up of patients with eosinophilia is not recommended.

Iron supplementation in children with celiac disease.

OBJECTIVE: To evaluate the effect of iron supplementation, in addition to gluten free diet (GFD), on hematological profile of children with Celiac Disease (CD). METHODS: Children diagnosed as CD as per modified ESPGAN criteria were prospectively evaluated for their hematological profile at the time of their enrolment and after consuming GFD for at least one year. The results were compared with age and sex matched controls. Evaluation of hematological profile included hemoglobin estimation, complete blood counts, peripheral blood smear examination, serum iron, total iron binding capacity (TIBC), and serum ferritin estimation. All the enrolled cases were given iron supplementation in addition to exclusion of gluten from their diet. Repeat intestinal biopsy was performed in all the cases after completing 1 year on GFD. RESULTS: Twenty one children (mean age 6.67 years, range 4-11 years) diagnosed as CD who completed at least one year of regular follow up on GFD (mean 1.5 years, range 1-2 years) were analysed for their hematological profile at the time of enrolment and after consuming GFD and iron supplementation. At the time of enrolment all the children had hemoglobin level <11 gm%, 78% had microcytic hypochromic anemia and 22% had dimorphic anemia, with lower mean MCV, MCH and serum ferritin levels, and a significantly higher mean TIBC as compared to controls (p<0.001). In the follow up evaluation of these cases on GFD, mean hemoglobin levels were comparable with controls but the cases continued to have lower mean MCV, MCH serum ferritin levels (p<0.05) and higher mean TIBC (p<0.05). Seven children had mild anemia. Serum ferritin levels showed a negative correlation with the grade of villous atrophy and lamina propria infiltrate. CONCLUSION: Our results suggest that iron deficiency anemia (IDA) is commonly associated with CD and iron deficiency state continues for a longer time even after excluding gluten from the diet and iron supplementation. Apart from offering them GFD rich in iron, early detection and treatment of IDA and prophylactic iron folic acid supplementation will go a long way to optimize their mental and psychomotor functions.

Clinical and nutritional profile of children with celiac disease.

This prospective study was aimed to evaluate the clinical and nutritional profile of children diagnosed as celiac disease (CD) as per the modified ESPGAN criteria, at the time of diagnosis and after institution of gluten free diet. Out of 65 enrolled cases of CD, 7 (10.8%) children did not follow a strict dietary compliance. Only 41 children with satisfactory dietary compliance on gluten free diet (GFD) who regularly attended the follow up for at least 6 months were evaluated for their nutritional and hematological status. Results were compared with age and sex matched controls. The mean age of diagnosis was 8.7 +/- 3.3 years. Diarrhea and failure to thrive were the most common presenting symptoms. At diagnosis, the nutritional and hematological indices were significantly lower in patients than in controls. Mean duration of follow up on GFD was 22 months (range 6-48 +/- 5.6 months). On follow up, height for age Z score was significantly lower, mean BMI was significantly higher, and weight for age Z score, weight for height Z score (%), mean triceps and biceps skin fold thickness, and mid arm circumference were comparable to controls. At diagnosis, 80% cases had microcytic hypochromic anemia and 20% had dimorphic anemia. On GFD for at least a period of more than 6 months, 19% had microcytic anemia and in 81% the hematological picture was normocytic normochromic. 60% cases had thrombocytosis at diagnosis in comparison to 2.3% after treatment. Institution of GFD leads to rapid improvement in clinical picture as well as most of the nutritional and hematological parameters.
