    Abstract Background: Colorectal cancer is one of the alarming health problems worldwide. Prognostic biomarkers are the key for risk stratification in patients with colon cancer and the decision to recommend adjuvant chemotherapy. It has been difficult to identify a single prognostic biomarker for colon cancer. Currently, tumor stage, tumor grade, and microsatellite instability remain the most important prognostic variables that aid in the treatment of patients with colon cancer. Some studies highlighted that CDX2 immunohistochemistry negativity is an independent prognostic factor and indicates a worse survival rate. Our aim was to study the prevalence of CDX2 biomarker expression in patients diagnosed with primary adenocarcinoma and to correlate this with the clinical profile and pathological features.
    Methods: Endoscopic mucosal biopsies and resection specimens of 148 patients diagnosed with colonic adenocarcinoma were analyzed. CDX2 immunohistochemistry was performed, and the result was correlated with clinicopathological features. The results were presented as mean, frequencies, and percentages. Pearson's Chi-square test was used to assess the associations between clinicopathological parameters and CDX2 immunohistochemistry negativity.
    Results: The prevalence of CDX2 expression by immunohistochemistry in colon cancer was found to be 92%. CDX2 biomarker negativity was found to be higher in left-sided colon cancers, poorly differentiated adenocarcinoma, mucinous carcinoma, and higher TNM stages.
    Conclusion: CDX2-negative tumors are often associated with several adverse prognostic variables (e.g., advanced stage, poor differentiation, and metastasis). Thus, sub-classification of colon cancer based on the CDX2 biomarker aids to separate them into prognostically relevant categories.

    Abstract Crohn's disease (CD) usually affects younger individuals but delayed-onset disease is not uncommon. We studied the epidemiology, demographic profile, and clinical characteristics of patients with delayed-onset CD (disease onset >50 years) and compared them with CD in younger individuals (disease onset 20-40 years) in a tertiary care center in India. The presenting symptoms, site of involvement, and treatment profile were similar, except for weight loss, which was more often noted in young-onset CD. However, granulomatous inflammation on mucosal biopsy was twice as common in young-onset compared to delayed-onset CD. As it is thus seen less often in delayed-onset CD, this may lead to a potential delay in diagnosis and treatment.

    Abstract Functional genes of HIV-1 like the tat express proteins essential for viral survival and propagation. There are variations reported in levels of Tat transactivation among the different subtypes of HIV-1. This study looked at the amino acid differences in the different regions of Tat protein (exon 1) of subtype B and C strains of HIV-1 and tried to observe a molecular basis for protein function. HIV-1 sequences of subtype B (n=30) and C (n=60) strains were downloaded from HIV-1 Los Alamos data base. Among the 60 subtype C strain sequences, 30 each were from India and Africa. A HIV-1 Tat protein (exon 1) sequence, the consensus B and C sequence was obtained from the 'sequence search interface' in the Los Alamos HIV-1 sequence data. The sequences were visualized using Weblogo and the RNA binding regions of the three consensus sequences were also determined using BindN software program. Compared to subtype B, there was a high level of divergence in the auxiliary domain of tat exon 1 (amino acid positions 58- 69). The net charge of the subtype C (Indian) Tat protein (exon 1) auxiliary domain was -1.9 at pH 7 and it had an isoelectric point of 4.1. The net charge of the subtype C (African) auxiliary domain was -2.9 at pH 7 and it had an isoelectric point of 3.7 while the net charge of same region in subtype B was -0.9 at pH 7 with an isoelectric point of 4.9. The ratio of the hydrophilic residues to the total number of residues was 60% in the in both the Indian and African subtype C in the auxiliary domain while this was 50% in subtype B. The consensus subtype B sequence was found to have 36 RNA binding sites while subtype C (India) had 33 and subtype C (Africa) had 32 RNA binding sites. The HIV-1 Tat-TAR interaction is a potential target for inhibitors and being considered for its potential use in HIV-1 vaccines. Development of such inhibitor/vaccines would have to take into consideration the variation in amino acid sequence analyzed in this study as this could determine epitope presentation on MHC class I antigen for afferent immune response.

    Abstract The advent of affordable ART has benefited HIV-infected individuals. Prospective studies have shown that the availability of drug resistance reports for infected individuals has allowed more effective regimens to be prescribed as compared to a control group whose physicians had no access to drug resistance reports. There is a paucity of information on the performance of genotypic algorithms on non-clade B HIV-1 strains, especially clade C. In this study the results obtained on submission of HIV-1 RT and PR sequences of non-clade B strains to the Stanford University HIV drug resistance database (SHDB) were compared to the results obtained from Geno2Pheno (G2P) and DR_Seqan (DS). For the study, we took samples from 93 treatment-naive individuals and 21 samples from 19 infected individuals showing detectable viral load while on ART. There were discrepancies in the clade identification results obtained from the SHDB and G2P databases. This feature was not available in DS. The mean observed concordance between SHDB and G2P was 85.6% while between SHDB and DC it was 37%. When the level of concordance was determined based on exposure to ART, the G2P was found to have a better level of concordance (76.8%) to SHDB as compared to SHDB versus DS (36%). We do not have phenotypic data for the strains included in this study and hence we are not in a position to assign a particular algorithm as being superior. These results also show a possible need for a subtype-specific algorithm for interpretation of HIV-1 genotypic drug resistance.

    Abstract Hyperacute GVHD (HaGVHD) is a rare complication of hematopoietic stem cell transplantation (HSCT) occurring before engraftment, a syndrome commonly involving skin and/or gut and/or liver, with increased morbidity and mortality. Myeloablative conditioning (MAC) regimes and mismatched donor transplants have an increased risk for HaGVHD. There is a higher chance of steroid-refractoriness and chronic GVHD in those who develop HaGVHD. There is limited literature about HaGVHD, especially in the paediatric age group. This retrospective single-centre case series included five paediatric patients who underwent HSCT between 1

    Abstract We report a probable case of abetalipoproteinemia in an infant who presented with unusual symptoms of late-onset vitamin K deficiency. Abetalipoproteinemia is a rare autosomal recessive disease caused by mutation of the microsomal triglyceride transfer protein gene, resulting in the absence of microsomal triglyceride transfer protein function in the small bowel. It is characterized by the absence of plasma apolipoprotein B-containing lipoproteins, fat malabsorption, hypocholesterolemia, retinitis pigmentosa, progressive neuropathy, myopathy, and acanthocytosis. A biopsy of the small intestine characteristically shows marked lipid accumulation in the villi of enterocytes. Large supplements of fat-soluble vitamins A, D, E, and K have been shown to limit neurologic and ocular manifestations. Dietary fat intake is limited to medium-chain triglycerides.

    Abstract Purpose: Assessment of disease activity in Crohn's helps predict important clinical outcomes. Among the various modalities available to assess disease activity, magnetic resonance enterography (MRE) is considered a safe and reliable imaging option. Various MRE-based scoring systems have been developed to measure disease activity, one of which being the MRE global score (MEGS). We aimed to correlate MEGS with some of the important indices of Crohn's disease activity.
    Methodology: Crohn's disease patients referred for MRE were included in the study. Along with demographic profile and relevant investigations, MRE parameters related to MEGS were also assessed.
    Result: A total of 47 patients were recruited for the study. Their median age was 34 years (range 18-68 years), and male:female ratio was 16:31. There was modest positive correlation between MEGS and faecal calprotectin (r = 0.3, p = 0.04), CRP level (r = 0.34, p = 0.02) and Harvey Bradshaw index (r = 0.3, p = 0.043), respectively. However, there was strong correlation between segmental MEGS and Simple Endoscopic Score in those with terminal ileal disease (r = 0.81, p < 0.001). Mural thickness was the only MRE parameter that correlated with active disease (OR - 1.35, 95% CI 1.01, 1.81, p = 0.041) on multivariate analysis. There was moderate inter-observer agreement (Lin's r = 0.78, p < 0.001).
    Conclusion: MEGS showed modest correlation with indices of Crohn's disease activity which corroborates the complementary role of MRE in management of such patients.

    Abstract Blood donors (35,395) were screened at the CMC Hospital, Vellore, in South India during the 2-year period from July 1986 to June 1988. They were either relatives of patients (referred to as replacement donors) or volunteers. Paid or professional donors were not accepted. Of the replacements 21.5% and of the voluntary donors 9.7% were rejected. Mean donor age was 32.2 years and the commonest blood group was O (39.46%), Rh positive (93.93%). Hepatitis B surface antigen was found in 1.37% and 2.96% of voluntary and replacement donors respectively. Anti-HIV antibodies were found in 1.9/1000 donors. This shows an increasing prevalence of HIV infection in the Indian donor population not reported earlier. The prevalences of malarial parasites and microfilaria in replacement donors were 0.02 and 1.62% respectively. In voluntary donors, malarial parasites were not found and microfilaria were found in only 0.15%. All rejection criteria except low haemoglobin were significantly more frequent among replacement donors than among voluntary donors. In the light of these results, screening of all donor blood for HBsAg and Anti-HIV by the most sensitive techniques and for malarial and filarial parasites in endemic areas is essential.
