Prevalence of Hepatitis D virus antibodies in Hepatitis B patients treated at tertiary care unit at Jabalpur Central India.

Hepatitis Delta virus (HDV) infection amongst Hepatitis B virus (HBV) infected patients increases morbidity and mortality. The prevalence varies temporally and spatially. The present study aimed to evaluate the HDV prevalence in central India. Samples received from January 2018 to December 2019 were tested for viral hepatitis markers. Randomly picked 372 HBsAg positive samples were tested for the presence of HDV total antibodies using ELISA, of these 8 were found positive. This study for the first-time documents presence of HDV with 2.1% prevalence from central India. We recommend screening for better patient management and bringing down the disease burden.

Sputum Proteomics Reveals a Shift in Vitamin D-binding Protein and Antimicrobial Protein Axis in Tuberculosis Patients.

Existing understanding of molecular composition of sputum and its role in tuberculosis patients is variously limited to its diagnostic potential. We sought to identify infection induced sputum proteome alteration in active/non tuberculosis patients (A/NTB) and their role in altered lung patho-physiology. Out of the study population (n = 118), sputum proteins isolated from discovery set samples (n = 20) was used for an 8-plex isobaric tag for relative and absolute concentration analysis. A minimum set of protein with at least log2(ATB/NTB) >±1.0 in ATB was selected as biosignature and validated in 32 samples. Predictive accuracy was calculated from area under the receiver operating characteristic curve (AUC of ROC) using a confirmatory set (n = 50) by Western blot analysis. Mass spectrometry analysis identified a set of 192 sputum proteins, out of which a signature of ß-integrin, vitamin D binding protein:DBP, uteroglobin, profilin and cathelicidin antimicrobial peptide was sufficient to differentiate ATB from NTB. AUC of ROC of the biosignature was calculated to 0.75. A shift in DBP-antimicrobial peptide (AMP) axis in the lungs of tuberculosis patients is observed. The identified sputum protein signature is a promising panel to differentiate ATB from NTB groups and suggest a deregulated DBP-AMP axis in lungs of tuberculosis patients.

Low dose hydroxyurea is effective in reducing the incidence of painful crisis and frequency of blood transfusion in sickle cell anemia patients from eastern India.

There are several questions pertaining to dosage, duration and potential long-term toxicity of hydroxyurea (HU) therapy. Use of HU is extremely limited in eastern India because of its high cost and apprehension of its toxicities. We undertook this study to assess the clinical, biochemical and hematological efficacy of minimal dose HU (10 mg/kg/day) in 118 sickle cell anemia patients (27 pediatric and 91 adults). The frequency of painful crises reduced significantly in 71.5 and 92.2% in pediatric and adult cases, respectively. Ninety-five percent of the patients became transfusion independent. The baseline Hb F, total hemoglobin (Hb), MCV, MCH and MCHC levels increased significantly, whereas the WBC, platelet count and total serum bilirubin values decreased significantly. This is the first study of minimal dose HU therapy in eastern India that showed impressive improvement in clinical and hematological parameters with minimal toxicity.
