Severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) has first emerged from China in December 2019 and causes coronavirus induced disease 19 (COVID19). Since then researchers worldwide have been struggling to detect the possible pathogenesis of this disease. COVID19 showed a wide range of clinical behavior from asymptomatic to severe acute respiratory disease syndrome. However, the etiology of susceptibility to severe lung injury is not yet fully understood. Angiotensin-converting enzyme1 (ACE1) convert angiotensin I into Angiotensin II that was further metabolized by ACE 2 (ACE2). The binding ACE2 receptor to SARS-CoV-2 facilitate its enter into the host cell. The interaction and imbalance between ACE1 and ACE2 play a crucial role in the pathogenesis of lung injury. Thus, the aim of this study was to investigate the association of ACE1 I/D polymorphism with severity of Covid-19. The study included RT-PCR confirmed 269 cases of Covid-19. All cases were genotyped for ACE1 I/D polymorphism using polymerase chain reaction and followed by statistical analysis (SPSS, version 15.0). We found that ACE1 DD genotype, frequency of D allele, older age (≥46 years), unmarried status, and presence of diabetes and hypertension were significantly higher in severe COVID19 patient. ACE1 ID genotype was significantly independently associated with high socio-economic COVID19 patients (OR: 2.48, 95% CI: 1.331–4.609). These data suggest that the ACE1 genotype may impact the incidence and clinical outcome of COVID-19 and serve as a predictive marker for COVID-19 risk and severity.

Problem statement:Cadmium is one of the most dangerous occupational and environmental toxins. It is found in drinking water, atmospheric air and even in food. Cadmium is reported to be very toxic to biological systems. Until now in treating intoxication with this metal, chelating Compounds have been used, burdened with numerous undesirable symptoms. For this reason, many researches are carried out in many countries to find natural-made compounds that help in the protection against cadmium induced toxicity with fewer or no side effects. This study was conducted to demonstrate the effect of daily oral Camel's milk administration against Cadmium chloride induced toxicity in white albino rats. Approach: White albino rats of both sexes (230-250 g) were housed in standard metal cages (6 rats/cage). The experimental rats (6 in each group) distributed into two experimental groups with a shared control group received only normal saline orally (Group 1). In experimental first group a daily dose (10 mg kg  1 body weight) of cadmium chloride was orally administrated to the rats for 21 days and named Cadmium chloride treated rats. In experimental second group, the same concentrations of cadmium chloride was dissolved in 2 mL of early morning fresh Camel's milk and the whole solution was administered into the experimental rats for 21 days and named Camel's milk cadmium chloride treated group. Water and food were provided ad libitum. Results: The data indicated that, in experimental Cadmium chloride treated rats, serum albumin, calcium and blood hemoglobin were decreased compared with control group received normal saline only. Moreover, Camel's milk administration with cadmium chloride showed a significant improvement of albumin, hemoglobin and calcium levels in the serum of the rats compared with cadmium chloride treated rats. Serum iron, sodium, chloride and urea levels were significantly increased in cadmium chloride treated rats compared with control group, while the addition of camel's milk to cadmium chloride decreased the high levels of these serum parameters in the treated rats. The enzyme activities of serum Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) and serum Alkaline Phaospatase (ALP) were significantly increased by orally administration of cadmium chloride compared with control group, while adding Camel's milk to cadmium chloride decreased the high levels of these enzymes comparing with the cadmium chloride treated rats. Cadmium chloride administration resulted in a high concentration of lipid peroxidation markers; TBARS and Hydroperoxides in comparison to control group, adding camel's milk to the cadmium chloride restored the levels of these markers to their normal levels in comparing to Cadmium chloride treated rats. Also treatment with cadmium chloride alone caused a significant decrease in both the enzymatic and nonenzymatic markers of oxidative stress (superoxide dismutase and catalase) and reduced glutathione, respectively in the liver tissues of treated rats, while the admini...

Coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection has become a global health issue and develops into a broad range of illnesses from asymptomatic to fatal respiratory diseases. SARS‐CoV‐2 infection is associated with oxidative stress that triggers cytokine production, inflammation, and other pathophysiological processes. Glutathione‐S‐transferase (GST) is an important enzyme that catalyzes the conjugation of glutathione (GSH) with electrophiles to protect the cell from oxidative damage and participates in the antioxidant defense mechanism in the lungs. Thus, in this study, we investigated the role of GSTM1 and GSTT1 gene polymorphism with COVID‐19 susceptibility, as well as its outcome. The study included 269 RT‐PCR confirmed COVID‐19 patients with mild ( n = 149) and severe ( n = 120) conditions. All subjects were genotyped for GSTM1 and GSTT1 by multiplex polymerase chain reaction (mPCR) followed by statistical analysis. The frequency of GSTM1 −/− , GSTT1 −/− and GSTM1 −/− /GSTT1 −/− was higher in severe COVID‐19 patients as compared to mild patients but we did not observe a significant association. In the Cox hazard model, death was significantly 2.28‐fold higher in patients with the GSTT1 −/− genotype ( p = 0.047). In combination, patients having GSTM1 +/+ and GSTT1 −/− genotypes showed a poor survival rate ( p = 0.02). Our results suggested that COVID‐19 patients with the GSTT1 −/− genotype showed higher mortality.

This is a retrospective single-center study of 417 consecutive patients with coronavirus disease 2019 (COVID-19) admitted to Jaber Al-Ahmad Hospital in Kuwait between February 24, 2020 and May 24, 2020. In total, 39.3% of patients were asymptomatic, 41% were symptomatic with mild/moderate symptoms, 5.3% were admitted to the intensive care unit (ICU) and recovered, and 14.4% died. The mean age of death cases was 54.20 years (S.D. 11.09). Comorbidities were more prevalent in patients who died compared with others. Key findings include abnormal levels of markers assicated with infection, inflammation, abnormal blood clotting, heart problems and kidney problems in patients with severe form of the disease and poor putcome. We report a rapidly deteriorating estimated glomerular filtration rate (eGFR) in deaths during ICU stay with kidney injury complications reported in 65% of deaths (p < 0.05). Our dynamic profiling of eGFR in ICU highlights the potential role of renal markers in forecasting disease outcome that could perhaps identify patients at risk of poor outcome.
