Background: Hematological abnormalities are a common complication of HIV infection. These abnormalities increase as the disease advances. Bone marrow abnormalities occur in all stages of HIV infection.

There are limited data on nonalcoholic fatty liver disease (NAFLD) from India. The clinicopathological profile of Indian patients with NAFLD may be different from that of Western patients. One hundred NAFLD patients with increased liver enzymes were prospectively evaluated for clinical presentation, associated diseases, overweight/obesity, central obesity (n=54), presence of diabetes mellitus, lipid abnormalities, insulin resistance (n=39), metabolic syndrome (n=54), serum iron, serum ferritin, and transferrin saturation (n=60), and HFE gene mutations (n=30). Risk factors for the grade and stage of the disease on histology were studied in 38 biopsy-proven patients. Patients were treated with lifestyle modifications and ursodeoxycholic acid (UDCA). Seventeen nonresponder patients were treated with metformin. The majority of patients were males (n=70). Twenty percent of patients were overweight, 68% had obesity, and 78% had central obesity. Abnormal cholesterol, HDL, and triglycerides were present in 36%, 66%, and 53% of patients, respectively. Twelve percent of patients had diabetes mellitus and 16% patients had various associated diseases. All 22 (100%) patients studied by ITT and all but 1 (98%) studied by HOMA-IR were found to have reduced insulin sensitivity and 50% were found to have metabolic syndrome by the modified ATP III criteria. Two (3%) patients were found to have high serum iron, 4 (7%) patients had high ferritin, 5 (8%) patients had increased transferrin saturation, and 4 (13%) patients were found to be heterozygotes for H63D HFE gene mutation. Twenty patients of 38 (53%) had histological evidence of NASH (class 3=6, class 4=14). The other 18 (47%) qualified for class I (n=1) or class II (n=17) NAFLD. Four (10.5%) patients had bridging fibrosis and none had evidence of cirrhosis liver. Seventy-four (74%) patients achieved a biochemical response to lifestyle modification and UDCA. All 17 patients treated with metformin had a reduction in ALT level and 10 (59%) of them had normalization of their enzymes. We conclude that the clinicopathological profile of NAFLD in Indian patients is different from that in the West.

Diagnostic approaches to the anemic cancer patient begin with a detailed clinical history and physical examination. Peripheral blood morphology and reticulocyte count are also helpful. Patients with unexplained anemia are evaluated by standard approaches also used in patients of similar age without malignancy. Serum iron profile and bone marrow examination are often required in difficult cases. This review focuses on major aspects of the pathogenesis of the individual entities. Diagnostic approaches and uncommon causes including hemophagocytic lymphohistiocytosis, acquired hemoglobinopathies, and myelodysplasia are also discussed.

Thalassaemia and sickle cell disease have been recognized by the World Health Organization as important inherited disorders principally impacting on the populations of low income countries. To create a national and regional profile of b-thalassaemia mutations in the population of India, a meta-analysis was conducted on 17 selected studies comprising 8,505 alleles and offering nearnational coverage for the disease. At the national level 52 mutations accounted for 97.5% of all b-thalassaemia alleles, with IVSI-5(G[C) the most common disease allele (54.7%). Population stratification was apparent in the mutation profiles at regional level with, for example, the prevalence of IVSI-5(G[C) varying from 44.8% in the North to 71.4% in the East. A number of major mutations, such as Poly A(T[C), were apparently restricted to a particular region of the country, although these findings may in part reflect the variant test protocols adopted by different centres. Given the size and genetic complexity of the Indian population, and with specific mutations for b-thalassaemia known to be strongly associated with individual communities, comprehensive disease registries need to be compiled at state, district and community levels to ensure the efficacy of genetic education, screening and counselling programmes. At the same, time appropriately designed community-based studies are required as a health priority to correct earlier sampling inequities which resulted in the under-representation of many communities, in particular rural and socioeconomically under-privileged groups.

Venous and arterial thrombotic complications can occur in children with nephrotic syndrome. A high index of suspicion is required as the clinical features may be subtle. Neuroimaging and angiographic techniques help in confirming diagnosis. Early aggressive heparin therapy followed by oral anticoagulants is necessary for a favorable outcome.
