Anaphylaxis as a Rare Side Effect of Pantoprazole; a Case Report

Anaphylaxis is a serious life-threatening allergic reaction. Any medication may potentially trigger anaphylaxis, but reaction to pantoprazole is rare. Our case is a 21 year-old girl with anaphylactic reaction to pantoprazole a short time after prescription

Recent Advances in Immunotherapeutic Approaches for Recurrent Reproductive Failure

Human reproduction is an insufficient process, disturbed by various factors, such as immunologic aberrations of mother. Immunologic abnormalities, including cellular and humoral immunity imbalance, cause dysregulated immune responses against embryo, fetus, and associated components and lack of maternal immunotolerance, which compromise the maintenance of pregnancy. Therefore, evaluation of immunologic parameters, including cellular and humoral immunity assessment (T and B lymphocyte, T helper subtypes, NK cells, cytokines, and autoantibodies), especially in women with a history of pregnancy loss or implantation failure, would help clinicians to manage the disorder and prevent next unfavorable pregnancy outcomes. Moreover, several immunomodulatory approaches have been introduced to modulate the abnormal immunologic responses in patients who experience reproduction failure, especially those diagnosed with immunologic basis. Anticoagulants, corticosteroids, intravenous immunoglobulin, immunosuppressive medications used in inhibition of graft rejection, such as calcineurin inhibitors, recombinant cytokines, and cell therapy approaches, are among these modalities. Here, we discuss the proposed mechanisms of immunologic abnormalities involved in the etiopathogenesis of reproduction disorders, besides the suggested immunologic tests and immunotherapeutic approaches which may be helpful in management of these disorders

HYSSOP and POLIUM could help to prevent COVID-19 in high-risk population: The results of a parallel randomized placebo-controlled field trial

243-253This study was conducted to evaluate the effect of HYSSOP (composed of Hyssopus officinalis L., Echium amoenum Fisch & C. A. Mey and Glycyrrhiza glabra L.) and POLIUM (contained Teucrium polium L., Cuscuta epithymum Murr and Cichorium intybus L.) combined distilled herbal medicines compared to placebo in the prevention of COVID-19. This is a double-blind parallel placebo-controlled field trial conducted on 751 asymptomatic individuals whose one of the family members recently had a positive RT-PCR test for COVID-19. They were divided into three groups including POLIUM, HYSSOP and placebo using random blocks with a 1:1:1 allocation ratio. Participants received daily 5 cc (under 12 years) or 10 cc (over 12 years) of allocated oral medications for 20 days. The primary outcome was the frequency of positive RT-PCR test among participants who became symptomatic. The mean age of participants was 36.6. Nineteen participants get infected by COVID-19 during the intervention; fifteen of them belonged to the placebo and four to the POLIUM group. Fisher's exact test indicated significant differences between HYSSOP and placebo (p<0.001) as well as POLIUM and placebo (p=0.009) groups in terms of COVID-19 confirmed by PCR tests. Cox regression model adjusted for confounders illustrated that the hazard of getting infection by COVID-19 in POLIUM and HYSSOP groups decreased by 66% (OR (95% CI): 0.34 (0.12 to 0.94); p=0.038) and 93% (OR (95% CI): 0.07 (0.01to 0.56); p=0.012) respectively, compared to placebo .Oral administration of HYSSOP and POLIUM with the other supportive health care could decrease the risk of getting COVID-19

Dietary acid load is associated with primary osteoporosis in postmenopausal women aged 50–65 years: A cross-sectional study

This study aimed to investigate the association between dietary acid load (DAL) and primary osteoporosis. This was a cross-sectional study. Among 850 randomly selected postmenopausal women aged 50–65 years, 232 women consisted of 124 women with normal bone mineral density (BMD) and 108 with primary osteoporosis were selected after examining the eligibility criteria. Demographic characteristics, anthropometric indices, and physical activity were collected through questionnaires. Osteoporosis was diagnosed using the dual-energy X-ray absorptiometry method. DAL was assessed by a valid and reliable semiquantitative food frequency questionnaire during the last year. Independent t-test, Mann–Whitney, Chi-square, and adjusted binary logistic regression were used for data analysis through SPSS/24. There were significant differences between the two groups in terms of age, body mass index (BMI), number of deliveries, and years after menopause (p &lt; .05). The mean (standard deviation (SD)) potential renal acid load (PRAL) and net endogenous acid production (NEAP) were higher in postmenopausal women with osteoporosis than those with normal BMD (PRAL: −13.1 ± 11.1 mEq/day vs. −10.8 ± 12.7 mEq/day; NEAP: 29.5 ± 8.5 mEq/day vs. 31.2 ± 9.2 mEq/day). The mean consumption of potassium, magnesium, and calcium in the osteoporosis group was significantly lower than in the other group (p &lt; .05). There were significant associations between osteoporosis with PRAL (odds ratio (OR) = 1.030; 95% confidence interval (CI): 1.001 to 1.060, p = .027) and NEAP scores (OR = 1.041; 95% CI: 1.003 to 1.081, p = .037). The odds of osteoporosis increased by 3% following one unit increase in PRAL score. Similarly, it increased by 4% with increasing NEAP score up to one unit. Therefore, dietary patterns that produce high DAL can have a detrimental effect on bone health

Cell-based therapy in thin endometrium and Asherman syndrome

AbstractNumerous treatment strategies have so far been proposed for treating refractory thin endometrium either without or with the Asherman syndrome. Inconsistency in the improvement of endometrial thickness is a common limitation of such therapies including tamoxifen citrate as an ovulation induction agent, acupuncture, long-term pentoxifylline and tocopherol or tocopherol only, low-dose human chorionic gonadotropin during endometrial preparation, aspirin, luteal gonadotropin-releasing hormone agonist supplementation, and extended estrogen therapy. Recently, cell therapy has been proposed as an ideal alternative for endometrium regeneration, including the employment of stem cells, platelet-rich plasma, and growth factors as therapeutic agents. The mechanisms of action of cell therapy include the cytokine induction, growth factor production, natural killer cell activity reduction, Th17 and Th1 decrease, and Treg cell and Th2 increase. Since cell therapy is personalized, dynamic, interactive, and specific and could be an effective strategy. Despite its promising nature, further research is required for improving the procedure and the safety of this strategy. These methods and their results are discussed in this article.</jats:p

Regulation of Dendritic Cell Functions by Vitamins as Promising Therapeutic Strategy for Immune System Disorders

A functional immune system is crucial for a healthy life, protecting from infections, tumors, or autoimmune disorders; these are accomplished by the interaction between various immune cells. Nourishment, particularly micronutrients, are very important components in the immune system balance, therefore this review emphasizes the vitamins (D, E, A, C) and Dendritic cells' subsets due to vitamins' roles in immune processes, especially on dendritic cells' functions, maturation, and cytokine production. Current studies reveal significant benefits related to vitamins, including vitamin E, which can contribute to the control of dendritic cells' function and maturation. Furthermore, vitamin D plays an immunoregulatory and anti-inflammatory role in the immune system. Metabolite of vitamin A which is called retinoic acid leads to T cells' differentiation to T helper 1 or T helper 17, so low levels of this vitamin exacerbate the menace of infectious diseases, and vitamin C has anti-oxidant effects on dendritic cells and modulate their activation and differentiation program. Additionally, the correlation between the amount of vitamin and the occurrence or progression of allergic diseases and autoimmunity disorders is discussed according to the results of previous studies

New insight into clinical heterogeneity and inheritance diversity of FBLN5-related cutis laxa

Abstract Background FBLN5-related cutis laxa (CL) is a rare disorder that involves elastic fiber-enriched tissues and is characterized by lax skin and variable systemic involvement such as pulmonary emphysema, arterial involvement, inguinal hernias, hollow viscus diverticula and pyloric stenosis. This type of CL follows mostly autosomal recessive (AR) and less commonly autosomal dominant patterns of inheritance. Results In this study, we detected a novel homozygous missense variant in exon 6 of FBLN5 gene (c.G544C, p.A182P) by using whole exome sequencing in a consanguineous Iranian family with two affected members. Our twin patients showed some of the clinical manifestation of FBLN5-related CL but they did not present pulmonary complications, gastrointestinal and genitourinary abnormalities. The notable thing about this monozygotic twin sisters is that only one of them showed ventricular septal defect, suggesting that this type of CL has intrafamilial variability. Co-segregation analysis showed the patients’ parents and relatives were heterozygous for detected variation suggesting AR form of the CL. In silico prediction tools showed that this mutation is pathogenic and 3D modeling of the normal and mutant protein revealed relative structural alteration of fibulin-5 suggesting that the A182P can contribute to the CL phenotype via the combined effect of lack of protein function and partly misfolding-associated toxicity. Conclusion We underlined the probable roles and functions of the involved domain of fibulin-5 and proposed some possible mechanisms involved in AR form of FBLN5-related CL. However, further functional studies and subsequent clinical and molecular investigations are needed to confirm our findings. </jats:sec
