RESUMO

Antibiotic resistance represents one of the biggest challenges, and there is an urgent need for plant-based antimicrobial agents that enable managing this crisis effectively. In this work, we aimed to investigate the antibacterial activity of Astragalus candolleanus (A. candolleanus) hydromethanolic root extract against Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Kocuria rhizophila) strains by the cup-plate method. The root was powdered and extracted with 70% methanol by cold maceration for 5 days. Preliminary phytochemical screening was performed with different solvents in the order of increasing polarity. Pure compounds were isolated by column chromatography and were characterized through liquid chromatography-mass spectrometry. Targeted predictions of the isolated compounds were also studied using Swiss Target prediction software and prediction of activity spectra for substances. The extract showed a broad zone of inhibition against pathogenic bacteria. Four pure compounds were isolated, of which a novel terpenoid compound has been identified as stemmadenine along with scillirosidin, cephalotaxine, and myxoxanthophyll. The structures of the isolated phytoconstituents were elucidated by spectral analysis. The four pure components isolated from the roots of A. candolleanus are suggested to be effective against tested pathogens. Overall results of drug design suggest that myxoxanthophyll is a promising bioactive compound endowed with antibacterial activity.

RESUMO

OBJECTIVE: To determine the prevalence of short stature, delayed puberty, hypothyroidism, and diabetes mellitus in multiply transfused patients of beta thalassemia major and their correlation with serum ferritin. METHODS: A descriptive observational study was conducted in a tertiary care center in Indore, Madhya Pradesh from 2014 to 2016. All children with thalassemia major of the age group 8 to 18 y attending outpatient department or admitted in ward were included in the study. Detailed clinical history, demographic data, compliance to transfusion and chelation therapy, and growth parameters were recorded. Blood samples to look for endocrinopathies and serum ferritin were assessed. Tanner staging was done to assess for delayed puberty. RESULTS: Mean age of study participants (n = 50) was 15.98 ± 3.4 y. Short stature (n = 44; 88%), delayed puberty (n = 33; 71.7%), hypothyroidism (n = 6; 16%), and diabetes mellitus (n = 5; 10%) were the endocrinal abnormalities found. Mean serum ferritin level was 3122 ± 2117 ng/mL. Serum ferritin had significant positive correlation with serum TSH (thyroid stimulating hormone), fasting blood sugars, postprandial blood sugar, and delayed puberty. CONCLUSION: Evaluation of endocrinopatines must be carried out in thalassemia major patients regularly by pediatricians to detect and treat endocrinal complications. Importance of chelation therapy must be emphasized frequently to parents and patients.

RESUMO

Acute intermittent porphyria (AIP) and ichthyosis vulgaris both are autosomal dominant disorders with incomplete penetrance caused by the deficiency of porphobilinogen deaminase enzyme and filaggrin protein, respectively. We report a rare case of a 9-year-old boy having two genetic diseases with an unclear association. An acute attack of AIP is characterized by gastrointestinal symptoms and neuropsychiatric manifestations. Although rare in the first decade of life, the presence of reddish urine with a typical presentation such as abdominal pain, hypertension, seizure, and paresthesias lead us to the diagnosis of AIP. The precipitating factor in the present case was prolonged fasting in Ramadan.
