Effect of heterologous platelet-rich plasma on liver and modulation of glucose metabolism and Wnt signalling pathways in diabetic mice.

BACKGROUND: The current study was designed to highlight the effects of heterologous platelet-rich plasma (PRP) on deteriorated hepatic tissues and impaired glucose metabolism of alloxan-induced diabetic mice. METHODS: 30 male mice were divided into a control (CG), PRP (PG), diabetic (DG), and two treated groups (T1G and T2G). PG was given PRP treatment (0.5 ml/kg body weight) twice a week for four weeks. DG, T1G and T2G were given alloxan (150 mg/kg) to induce diabetes. After confirmation, PRP treatment was given to T1G and T2G for two and four weeks respectively while DG was left untreated. Upon completion of the said experimental period, liver samples were taken for histological and gene expression analyses. RESULTS: The study found that the liver tissue of the DG group showed signs of damage, including hepatocyte ballooning, sinusoid dilatation, and collagen deposition. However, these changes were significantly reduced in both T1G and T2G groups. The expression of several genes related to liver function was also affected, with upregulation of Fbp1 and Pklr, and downregulation of Pck1 in the DG group. PRP treatment restored Fbp1 expression and also increased the expression of glycolytic pathway genes Hk1 and Gck, as well as Wnt signalling pathway genes Wnt2, Wnt4, and Wnt9a in both treated groups. CONCLUSION: Current study revealed that heterologous PRP may partly alleviate high glucose levels in diabetics possibly by mediating glucose metabolism via inhibition of Wnt signalling pathway.

Profiling of inflammatory biomarkers in mild to critically ill severe acute respiratory syndrome corona virus-19 (SARS Covid-19) patients from Karachi, Pakistan.

SARS-Covid-19 infection got spread in many countries and WHO declared it as a serious global Pandemic. Pro-inflammatory cytokines storm generated by Covid-19 infection hyper-activates inflammatory response in host body, resulting in elevated release of inflammatory biomarkers. Present article describes the characteristic profile of these inflammatory and related biomarkers in a total of 48 critically ill Covid-19 patients, (Male = 38, F = 10), with mildly ill to severe, critically ill status and thus grouped accordingly. Inflammatory Biomarkers, Ferritin, ProCalcitonin, C-Reactive Protein, coagulation marker-D-Dimer, chemical analytes, Protein, Albumin, BUN, Bilirubin, Creatinine, and enzymes, Lactate Dehydrogenase, γ-Glutamyl transpeptidases, Alkaline phosphatase were routine analyzed by standard methods described earlier. D-dimer, Ferritin, CRP and Procalcitonin exhibited variable alterations (P<0.05 to P<0.001), more markedly in critically ill patients than in the mild and severe. Biochemical analytes and enzymatic parameters showed elevated levels (P<0.05 to P<0.01) mostly in critically ill category of patients when compared with mild or severe, except total protein and albumin, which remained non-significant. It is concluded that cytokine, chemokines and pro-inflammatory markers, which released in abnormally high concentrations in Covid-19 patients of variable syndrome intensity, are significant indicators of disease severity, progression and success of treatments. As the pharmacological options may vary with the different stages of the disease therefore identifying the correct stage of the disease may be very useful in selecting the best option.

REPORT- Varying pattern of blood gases, ferritin, procalcitonin, C-Reactive protein, interleukin 6 and lactate dehydrogenase in Covid-19 patients suffering from diverse Co-Morbid, suspected cytokine storm and periodic effects of antiviral and steroidal treatments.

This study depicted varying pattern of inflammatory markers and blood gases of selected SARS Covid-19 patients with triggered cytokine storm, during their stay in ICUs, HDUs, on ventilators for 21 days. All were treated with Antiviral (remdesivir), steroid (dexamethason) and antipyretic (paracetamol) medications. Procalcitonin, PCT, C-reactive protein CRP, Interleukin 6 (IL6) and Lactate dehydrogenase (LDH) blood gases pressure (pO2, pCO2), coagulation (D-Dimer DD) and Iron storage proteins (Ferritin Ft) were analyzed by fully automated analyzers. All biomarkers of each patient category was statistically compared with days 1st, 4th, 7th versus 10th, 14th and 17th days and reported as significant where p<0.05, to assess progression, worsening or recovery status. IL6 (P<0.0224, P< 0.0228) and CRP (P<0.0277) exhibited none or mild statistical significance difference, with the exception of Ferritin (P<0.0185; P<0.0088) and D Dimer (P<0.0086), demonstrating slow recovery, revealing stronger cytokine storming assault. LDH, pCO2 and pO2 exhibited variable significance difference when data of earlier days were compared with recovery phase, thus advocating blended treatment or progressing of disease. Analysis confirms overwhelming pathogenesis of SARS Covid-19 distinctive cytokine storm, which needed to be cautiously monitored as infection progressed using pro-inflammatory biomarkers as indicators of recovery or worsening of the disease.

Etiopathogenesis and risk factors for placental accreta spectrum disorders.

Placenta accreta spectrum (PAS) disorders, comprising placenta accreta, increta, and percreta, are associated with serious maternal morbidity and mortality in both the developed and the developing world. The incidence of PAS has increased in the recent years, and the rising rates of cesarean section rate, placenta accreta in previous pregnancies, and other uterine surgeries including myomectomies and repeated endometrial curettage are implicated in its etiopathogenesis. The absolute risk of PAS increases with the number of previous cesarean sections. The PAS remains undiagnosed in one-half to two-thirds of cases, thus increasing maternal morbidity and mortality. Understanding etiopathogenesis and risk factors of this condition allows early diagnosis and planning of delivery, and thereby would help improve maternal and fetal outcomes.
