Abstract Background Recent studies have indicated that females with coronavirus disease 2019 (COVID-19) have a lower morbidity, severe case rate, and mortality and better outcome than those of male individuals. However, the reasons remained to be addressed. Methods To find the factors that potentially protect females from COVID-19, we recruited all confirmed patients hospitalized at 3 branches of Tongji Hospital (N = 1902), and analyzed the correlation between menstrual status (n = 509, including 68 from Mobile Cabin Hospital), female hormones (n = 78), and cytokines related to immunity and inflammation (n = 263), and the severity/clinical outcomes in female patients <60 years of age. Results Nonmenopausal female patients had milder severity and better outcome compared with age-matched men (P < .01 for both). Menopausal patients had longer hospitalization times than nonmenopausal patients (hazard ratio [HR], 1.91 [95% confidence interval {CI}, 1.06–3.46]; P = .033). Both anti-Müllerian hormone (AMH) and estradiol (E2) showed a negative correlation with severity of infection (adjusted HR, 0.146 [95% CI, .026–.824], P = .029 and 0.304 [95% CI, .092–1.001], P = .05, respectively). E2 levels were negatively correlated with interleukin (IL) 2R, IL-6, IL-8, and tumor necrosis factor alpha in the luteal phase (P = .033, P = .048, P = .054, and P = .023) and C3 in the follicular phase (P = .030). Conclusions Menopause is an independent risk factor for female COVID-19 patients. AMH and E2 are potential protective factors, negatively correlated with COVID-19 severity, among which E2 is attributed to its regulation of cytokines related to immunity and inflammation.

Background The crucial role cytokines play in the pathophysiologyof sepsis is widely accepted. Infection stimulates the productionof cytokines in various cell types. Tumor necrosis factor-alpha(TNF-a) is one of the most extensively investigated cytokines inexperimental and clinical sepsis. Tumor necrosis factor-alpha hasbeen shown to mediate lethality in experimental sepsis.Objective To evaluate for a possible correlation between TNF-alevel and septic shock in children.Methods This cross-sectional study was conducted in Manadofrom June to September 2011. A total of 40 patients with arecent diagnosis of sepsis or septic shock were included. Plasmaspecimens were collected from subjects for measurement ofTNF-a concentration. Logistic regression analysis was used toassess the correlation between TNF-a level and sepsis, as well asthe probability of shock in children with sepsis, with P<0.05 asstatistically significant.Results There was a strong positive correlation betweenTNF-a level and the probability of shock in children with sepsis(regression coefficient = 0. 78, P = 0.002).Conclusions There is a strong positive correlation betweenTNF-a level with the probability of shock in children with sepsis.Higher plasma level ofTNF-a is associated with higher probabilityof septic shock.

Summary: The aim of our study was to compare the performance of mucosal immunity in urine and saliva of patients with chronic recurrent pyelonephritis subject to availability of hyperoxaluria. Material and methods. To observational cross–sectional study included 40 women with chronic recurrent pyelonephritis, aged 21 to 48 years (31.6±7.7). Depending on the availability hyperoxaluria (oxalate excretion in the urine than 0.45 mmol per day) patients were divided into II Groups: for I (n=29) included women with hyperoxaluria, to II (n=11) – includes patients with normal excretion oxalate (7.2±2.4 vs 43.8±5.2; p <0.001). State of mucosal immunity was assessed by determining the content of lysozyme, lactoferrin, secretory immunoglobulin A (sIg A) and tumor necrosis factor alpha (TNF– a) in urine samples and content sIg A and class antibodies sIg A to lipopolysaccharide (LPS) of gram–negative bacteria (anti–LPS–sIgA) in saliva. Results. We have identified significantly higher levels of sIg A and anti–LPS–sIgA in the saliva ofpatients with recurrent pyelonephritis with hyperoxaluria (298±104 vs 150.1±79.3 mg/1, p<0.001) and (0.353±0.16 vs 0.211±0.09, p<0.001), respectively. In the urine ofwomen of group I we havefound a statistically significant increase in the content of TNF– a 44 [16.2–130.5] vs 21 [14.2–3.45] pg/ml (p=0.04) and lysozyme 14.0[2.5– 36.5]vs 1.45[0.12–7.5]ng/ml (p=0.002). All the studied parameters (anti–LPS–sIg A in saliva and sIg A, lactofer– rin and lysozyme urine) had a direct correlation with the level of daily oxalate excretion.   Conclusions. Overproduction of indicators of mucosal immunity may be explained by the formation of intestinal dysbiosis under the influence of continuous antibiotic therapy. The imbalance of intestinal microflora, in turn, leads to the formation of hyperoxaluria and increases the production of antibodies to LPS, sIg A, lactoferrin and lysozyme.

Conflicting results have been published concerning the systemic induction of the cytokine tumor necrosis factor alpha (TNFα) during hemodialysis (HD). We therefore evaluated in vitro TNFα production in whole blood as well as in vivo variability of TNFα levels in patients on long-term HD. Whole blood was incubated at room temperature (RT) with or without exogenously added endotoxin (ET), and plasma-TNFα was measured after 5, 30, 120, 240, and 960 min by specific enzyme immunoassay. Additionally, plasma-TNFα before and after 120 and 240 min HD was studied longitudinally once a week over a period of 4 weeks in 36 patients on Cuprophan® (CU, n=23) or polysulfone-F60 (PSu, n=13) HD. Mean plasma TNFα levels in vitro rose from (mean) 8 pg/ml after 5 min to 12 pg/ml (120′) and 32 pg/ml (960′) even without ET addition, and to 18 pg/ml (after 120′) and 88 pg/ml (after 960′) when 0.1 μg/ml ET were added. Pre-dialytic as well as intradialytic TNFα levels in patients showed high intra-individual variability. A substantial (> 100%) increase in plasma TNFα was observed during only 14 out of 84 treatments with CU and 20 out of 47 with PSu, however, the increase in TNFα was not statistically significant in either group. We conclude that the sampling procedure, if not carefully standardized, is a potential source of artifacts with regard to “systemic” TNFα levels. The high intra and inter-individual variability of plasma TNFα suggests that results of cross-sectional studies are questionable.

Stunting is a disturbance in linear growth. Defi ciency of micronutrients such as vitamin A, zinc, and iron may disturb secretion of growth hormone. Infection may improve Tumor Necrosis Factor Alpha (TNF-α) and Interleukin 1 (IL-1)that pressing secretion of growth hormone. The purpose of this study is to determine difference adequacy levels of vitamin A, zinc, iron and frequency infection in stunting and non stunting children under fi ve at Puskesmas BulakBanteng Surabaya. The study was conducted from January to may 2017 with cross sectional design. Thirty-eight children (19 stunting and 19 non stunting) were selected from random sampling. Mann Whitney test was conducted to analyze the differences between variabel in stunting and non stunting. Variable that were signifi cantly different between two groups were vitamin A (p=0.002), zinc (p=0.003) and iron adequacy level (p=0.030). There were no signifi cant differences in frequency of diarrhea and acute respiratory infection among both groups. Vitamin A, zinc, and iron intake should be fullfi lled in order to prevent stunting.

The emergence of the novel coronavirus and then pandemic outbreak was coined 2019- nCoV or COVID-19 (or SARS-CoV-2 disease 2019). This disease has a mortality rate of about 3·7 percent, and successful therapy is desperately needed to combat it. The exact cellular mechanisms of COVID-19 need to be illustrated in detail. This study aimed to evaluate serum cytokines in COVID-19 patients. In this study, serum was collected from volunteer individuals, moderate COVID-19 patients, severe cases of COVID-19 patients, and patients who recovered from COVID-19 (n = 122). The serum concentrations of interleukins such as IL-1, IL-4, IL-6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α), were measured by enzyme-linked immunosorbent assays (ELISA). The concentrations of IL-1 and TNF-α were did not differ significantly among groups. However, the concentration of IL-6 was significantly higher in moderate COVID-19 and severe cases of COVID-19 groups compared to control and recovered groups indicating it to be an independent predictor in the coronavirus disease. The levels of IFN-γ and IL-4 were significantly lower in the recovery group than the severe case of the COVID-19 group. In contrast, the level of IL-10 in recovered COVID-19 patients was significantly higher in compare to severe cases, COVID-19 patients. Varying levels of cytokines were detected in COVID-19 group than control group suggesting distinct immunoregulatory mechanisms involved in COVID-19 pathogenesis. However, additional investigations are needed to be to be performed to understand the exact cellular mechanism of this disease.
