RESUMEN

Background: Familial hypocalciuric hypercalcemia (FHH) is a hypercalcemic syndrome that is usually characterized by uncomplicated hypercalcemia and normal longevity. The inheritance pattern is autosomal dominant with high penetrance, and it affects both men and women equally. FHH is caused by mutations that disturb the normal functioning of the calcium-sensing receptor (CaSR) gene. This causes a general lack of sensitivity to calcium, eventually leading to hypercalcemia and low calcium levels in the urine. Case Description: We report a case of a healthy 24-year-old female with longstanding hypercalcemia and a family history indicating asymptomatic hypercalcemia. The patient was also asymptomatic and had no significant past medical or surgical history. Laboratory investigations and the genetic study revealed findings suggestive of FHH subtype 1. Conclusions: The phenotype of FHH is normal, and symptoms of hypercalcemia are usually not present. Patients with FHH and hypoparathyroidism have lower calcium clearance than controls with hypoparathyroidism. This shows that relative hypocalciuria in FHH is not caused by hyperparathyroidism. Since calcium does not appropriately suppress or affect the parathyroid glands in FHH, this means that FHH is a disorder of abnormal transport of extracellular calcium and/or response to it in at least two organs, the parathyroid gland and the kidney. It is quite similar to primary hyperparathyroidism (pHPT) biochemically hence it is important to differentiate this condition from pHPT and hypercalcemia caused by other diseases to avoid any unnecessary surgical or medical intervention.

RESUMEN

Antimicrobial resistance (AMR) is considered as a global health and development threat. During COVID-19 pandemic, there has been an increase in antimicrobial resistance. Health care providers (HCPs) play the main role in facing antibiotic resistance because they have the authority to prescribe antibiotics during clinical practice as well as in promoting patients' compliance with therapies and avoid self-medication. So, this study will serve as an important source of information in context with Covid19 pandemic in Egypt. The data was collected using a validated standardized self-administered online questionnaire compromised of four sections: socio-demographic data of the HCPs, the general knowledge on antibiotics and AMR, the HCP attitude towards antibiotic prescription and AMR and the practice in applying the appropriate antibiotic prescription. Most of HCPs (93.7%) recorded good knowledge level about antibiotic prescription and antimicrobial resistance with mean score of knowledge13.21 ± 1.83. About 79% of HCPs recorded a positive attitude towards proper antibiotic prescription with mean score of attitudes 63.02 ± 7.68. Fifty four percent of HCPs demonstrated a good level of practice with mean score of practice 9.75 ± 2.17. In conclusion, HCPs in our study have a good level of knowledge and attitude about antibiotics. However lower level of proper practice towards the problem of AMR in COVID19 era was noticed. Implementation of effective policies and guidelines is crucial to evaluate the antimicrobial use especially in the COVID-19 era to reduce the unintended consequences of the misuse of antibiotics and its impact on AMR.

RESUMEN

OBJECTIVES: To investigate the frequency of toll-like receptor 4 (TLR4) variants c.896A>G (p.Asp299Gly) and c.1196C>T (p.Thr399Ile) among Egyptian children with primary immune thrombocytopenia (pITP), and their association with disease course and response to treatment. METHODS: A case-control study that included 80 children with pITP and 50 age- and sex-matched healthy controls. TLR4 c.896A>G and c.1196C>T variants were genotyped using polymerase chain reaction-restriction fragment length polymorphism. Patients were classified according to their response to treatment after 3 months as responders and nonresponders. RESULTS: Compared with controls, children with pITP had significantly higher minor allele frequencies of TLR4 p.Asp299Gly (16.25% vs. 6%, odds ratio [OR] 3.04, 95% confidence interval [CI]: 1.16-9.36, p = .014) and p.Thr399Ile (20% vs. 4%, OR 6, 95% CI: 2.02-24.01, p < .001). The presence of p.Asp299Gly variant was significantly associated with chronic ITP (OR 7.78, 95% CI: 2.04-35.69, p < .001) and non-response to therapy with steroid (OR 11.67, 95% CI: 1.32-104.08, p = .012), but not thrombopoietin-receptor agonist (OR 1.67, 95% CI: 0.35-8.19, p = .464). Likewise, having p.Thr399Ile variant was significantly associated with chronic ITP (OR 5.14, 95% CI: 1.6-17.4, p = .002) and non-response to therapy with steroid (OR 6.1, 95% CI: 1.01-49.06, p = .046) but not thrombopoietin-receptor agonist (OR 1.57, 95% CI: 0.33-7.58, p = .515). CONCLUSION: The presence of TLR4 p.Asp299Gly or p.Thr399Ile variant may be associated with ITP predisposition, chronicity, and non-response to upfront steroid therapy. These findings enhance our understanding of the complex pathophysiology of pITP with potentially important clinical implications.

RESUMEN

Diabetes mellitus (DM) is a chronic metabolic disorder that threatens human health. Medicinal plants have been a source of wide varieties of pharmacologically active constituents and used extensively as crude extracts or as pure compounds for treating various disease conditions. Thus, the aim of this study is to assess the anti-hyperglycemic and anti-hyperlipidemic effects and the modes of action of the aqueous extracts of the fruits and seeds of Balanites aegyptiaca (B. aegyptiaca) in nicotinamide (NA)/streptozotocin (STZ)-induced diabetic rats. Gas chromatography-mass spectrometry analysis indicated that 3,4,6-tri-O-methyl-d-glucose and 9,12-octadecadienoic acid (Z,Z)- were the major components of the B. aegyptiaca fruit and seed extracts, respectively. A single intraperitoneal injection of STZ (60 mg/kg body weight (b.w.)) 15 min after intraperitoneal NA injection (60 mg/kg b.w.) was administered to induce type 2 DM. After induction was established, the diabetic rats were treated with the B. aegyptiaca fruit and seed aqueous extracts (200 mg/kg b.w./day) via oral gavage for 4 weeks. As a result of the treatments with the B. aegyptiaca fruit and seed extracts, the treated diabetic-treated rats exhibited a significant improvement in the deleterious effects on oral glucose tolerance; serum insulin, and C-peptide levels; liver glycogen content; liver glucose-6-phosphatase and glycogen phosphorylase activities; serum lipid profile; serum free fatty acid level; liver lipid peroxidation; glutathione content and anti-oxidant enzyme (glutathione peroxidase, glutathione-S-transferase, and superoxide dismutase) activities; and the mRNA expression of the adipose tissue expression of the insulin receptor ß-subunit. Moreover, the treatment with fruit and seed extracts also produced a remarkable improvement of the pancreatic islet architecture and integrity and increased the islet size and islet cell number. In conclusion, the B. aegyptiaca fruit and seed aqueous extracts exhibit potential anti-hyperglycemic and anti-hyperlipidemic effects, which may be mediated by increasing the serum insulin levels, decreasing insulin resistance, and enhancing the anti-oxidant defense system in diabetic rats.

RESUMEN

Ataxia Telangiectasia (AT) is a very rare autosomal recessive primary immune deficiency (PID) disease that affects 1 in 10,000-40,000 new births per year in the world. It is caused by biallelic mutations in ataxia telangiectasia mutated (ATM) gene and characterized by a progressive cerebellar ataxia. The clinical profile of AT children in Upper Egypt in missing. Herein, we evaluated the clinical characteristics and immunological profiles of patients with AT attending Sohag University Hospital. This was a cross-sectional study, included 21 AT patients attending the Neurological and Immunological Units, Pediatric Department, Sohag University Hospital, starting April 2018 to the end of March 2019. AT represented 20.5% of all PID patients attending the hospital. The most common type of humoral immune deficiency in patients with AT was specific IgA deficiency (52.3%) followed by hypogammaglobulinemia (23.8%). Recurrent sinopulmonary infection with different degrees of severity was the common immunological problem. The most common neurological manifestations in our studied patients, other than the ataxia, were language delay and eye movement abnormalities followed by developmental delay and head nodding. None of our patients had developed malignancy till the end of the study.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the effects of ischemic pressure (IP) vs postisometric relaxation (PIR) on rhomboid-muscle latent trigger points (LTrPs). METHODS: Forty-five participants with rhomboid-muscle LTrPs were randomly assigned into 3 groups and received 3 weeks of treatment-group A: IP and traditional treatment (infrared radiation, ultrasonic therapy, and transcutaneous electrical nerve stimulation); group B: PIR and traditional treatment; and group C: traditional treatment. Shoulder pain and disability, neck pain and disability, and pressure pain threshold (PPT) of 3 points on each side were measured before and after treatment. RESULTS: Multivariate analysis of variance indicated a statistically significant Group × Time interaction (P = .005). The PPT for the right lower point was increased in group A more than in groups B or C. Neck pain was reduced in group B more than in group C. Moreover, shoulder and neck disability were reduced in both groups A and B more than in group C. The PPTs of the left lower and middle points were increased in group B compared with groups A and C. The PPT of the left upper point was increased in group A more than in group C. There were significant changes in all outcomes in the 2 experimental groups (P < .05). No changes were found in the control group except in pain intensity, shoulder disability, and PPT of the left lower point. CONCLUSION: This study found that IP may be more effective than PIR regarding PPT, but both techniques showed changes in the treatment of rhomboid-muscle LTrPs.

RESUMEN

Chronic granulomatous disease (CGD) is a rare inherited primary immunodeficiency disorder that affects phagocytes and is characterized by a marked increased susceptibility to severe bacterial and fungal infections. We aimed to describe the clinical presentations of pediatric patients with CGD in Upper Egypt and to identify the defective component of NADPH oxidase. Pediatric patients diagnosed with CGD within one year from January 2018 to January 2019 were enrolled in the study. Patient history, clinical and laboratory investigations were carried out, including nitroblue tetrazolium test and flow cytometry DHR analysis. Infectious microorganisms were isolated from infected sites to identify the causative agents and their resistance profile. A total of 15 patients were diagnosed with CGD. Failure to thrive and lymphadenopathy were the most common presentations. The median age of clinical onset was 1.17 years of age. The most common gene mutations were observed in the CYBA gene. All cases showed pulmonary infections followed by abscesses. Staphylococcus aureus and Klebsiella pneumoniae were the most frequently isolated bacterial pathogens, Aspergillus spp and Candida spp were isolated from fungal infections. 4/15 (26.7%) children died due to severe serious infections. We concluded that CGD is common in Upper Egypt, and we recommend raising the awareness and testing for CGD in pediatric patients with recurrent or persistent infections, especially those with a familiar history of similar manifestations to avoid delays in proper diagnosis and deterioration of cases. Abbreviations: CGD: chronic granulomatous disease; XL: X-linked; AR: autosomal recessive.

RESUMEN

This study is aimed at assessing the antihyperglycemic, antihyperlipidemic, and antioxidant effects of Citrus reticulata (C. reticulata) fruit peel hydroethanolic extract and two flavonoids, hesperidin and quercetin, in nicotinamide (NA)/streptozotocin- (STZ-) induced type 2 diabetic rats. In addition, GC-MS and HPLC-MS analyses of the extract were performed and the results indicated the presence of multiple flavonoids including hesperidin, quercetin, naringin, and polymethoxylated flavones (nobiletin and tangeretin). To achieve the aim of the study, diabetic rats with NA/STZ-induced T2DM were orally treated with C. reticulata fruit peel hydroethanolic extract, hesperidin, and quercetin at a dose of 100 mg/kg b.w./day for four weeks. The treatments with C. reticulata fruit peel extract, hesperidin, and quercetin significantly ameliorated the impaired oral glucose tolerance; the elevated serum fructosamine level; the diminished serum insulin and C-peptide levels; the altered HOMA-IR, HOMA-IS, and HOMA-ß cell function; the decreased liver glycogen content; the increased liver glucose-6-phosphatase and glycogen phosphorylase activities; the deleteriously affected serum lipid profile; the elevated serum AST and ALT activities; and the raised serum creatinine and urea levels in the diabetic rats. The treatments also produced remarkable improvement in the antioxidant defense system manifested by a decrease in the elevated liver lipid peroxidation and an increase in the lowered glutathione content and GPx, GST, and SOD activities. Furthermore, the three treatments enhanced the mRNA expression of GLUT-4 and the insulin receptor ß-subunit, but only quercetin produced a significant increase in the expression of adiponectin in adipose tissue of diabetic rats. In conclusion, C. reticulata fruit peel hydroethanolic extract, hesperidin, and quercetin have potent antidiabetic effects which may be mediated through their insulinotropic effects and insulin-sensitizing actions. In addition, the alleviation of the antioxidant defense system by the extract, hesperidin, and naringin may have an important action to enhance the antidiabetic actions and to improve liver and kidney functions in NA/STZ-induced diabetic rats.

RESUMEN

Ginger (Zingiber officinale Roscoe) is a valuable culinary and medicinal plant. The compound 6-gingerol is the main gingerol in ginger rhizomes and it possesses interesting pharmacological and physiological properties. Mutation breeding involved using low doses of gamma radiation (5-30 Gy) to increase the genetic variability in ginger rhizomes (M1 generation). Ginger plants selected from the next generation (M2) were characterized and subjected to quantitative analysis for 6-gingerol content using HPLC of ginger extracts. M2 offspring from a parent ginger rhizome irradiated with 20 Gy was found to have a high 6-gingerol content (38.4 ± 0.01 mg/g methanol extract in comparison to 22.1 ± 0.03 mg/g methanol extract in non-irradiated control samples). Radiation induced genetic variability was also probed and confirmed using RAPD-PCR analysis. This research demonstrates the potential for ginger improvement and to our knowledge is the first to report the use of gamma radiation in breeding ginger plants with enhanced 6-gingerol content.

RESUMEN

BACKGROUND: The link between Vitamin-D deficiency and type 2 diabetes (T2D) is well-established. Since prediabetic obese populations have the greatest risk to develop to T2D, it was important in our study to examine serum 25(OH) D3 concentration among prediabetic obese patients and to evaluate the correlation between serum level of vitamin D and BMI, FBS, HOMA IR and HbA1c among prediabetes patients. METHODS: A multicenter case control study was carried out among 101 prediabetic persons & 50 controls, after obtaining consent from subjects and clearance from institutional ethics committee. Serum vitamin D level, Plasma levels of glycosylated hemoglobin (HbA1c) and fasting insulin levels were measured by ELISA in both groups enrolled in the study. RESULTS: The prevalence of vitamin-D deficiency/insufficiency was (73.3%) (n = 74) among 101 prediabetic obese individuals. Also, A significant inverse correlation was observed between vitamin D levels & body mass index(r = - 0.28, P = 0.004); fasting blood sugar (r = - 0.22, P = 0.002); HOMA insulin resistance (r = - 0.25 P = 0.01); HbA1C (r = - 0.2, P= 0.004). CONCLUSIONS: High prevalence of vitamin D deficiency exists among obese prediabetic individuals and there is significant inverse correlation between BMI, FBS, HOMA IR, HbA1c and vitamin D level.

RESUMEN

Developing drought tolerance in Egyptian cotton varieties is a strategic goal considering the need to expand cotton cultivated area and water scarcity in the Nile valley. In the present study, increasing levels of polyamine accumulation via expressing S-adenosyl methionine decarboxylase (SAMDC) gene was the main goal. SAMDC cDNA isolated from Saccharomyces cerevisiae isolate was isolated and genetically engineered into Egyptian cotton varieties Giza 88 as an extra long staple and Giza 90 as a long staple by means of particle bombardment through meristem transformation.T(0) transgenic plants were screened using basta herbicide (200 mg/l). RT- PCR analysis was used to confirm gene expression while gene integration was confirmed by Southern blot analysis. Control plants from Giza 88 and Giza 90 were subjected to drought regime using different concentrations of PEG 6000 (2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17%, and 20%) for 9 hrs to record drought stress symptoms and determine the potential concentration level for inducing polyamine accumulation. 17% of PEG 6000 was considered the sublethal concentration showing drought stress symptoms and therefore was used as potential stress concentration for estimating the level for spermine accumulation in both control and transgenic Giza varieties. T(1) transgenic plants grown under induced drought stress regime were tested positive for gene integration and expression and subjected to HPLC analysis to determine levels of spermine as polyamine accumulated compound in response to drought stress regime. Elevated spermine accumulation in Egyptian cotton varieties Giza 88 and Giza 90, were compared as non transgenic plants grown under same induced drought conditions with T(1) transgenic plants using reverse-phase HPLC analysis. Elevated spermine accumulation expressing SAMDC gene reflect main cause for increasing drought tolerance in both transgenic varieties.
