Background: The inflammasome is a complex of proteins in the cytoplasm that consists of three main components: a sensor protein (receptor), an adapter protein and caspase-1. Inflammasomes are the critical components of innate immunity and have been gradually recognized as a critical mediator in various autoimmune diseases; also, their role in chronic kidney disease and acute kidney injury has been gradually accepted. Summary: Inflammasomes triggered by infectious or sterile injuries transfer proinflammatory mediators into mature ones through innate danger-signaling platforms. Information on inflammasomes in kidney disease will help to uncover the underlying mechanisms of nephropathy and provide novel therapeutic targets in the future. Key Messages: The inflammasomes can be activated by a series of exogenous and endogenous stimuli, including pathogen-and danger-associated molecular patterns released from or caused by damaged cells. The NACHT, LRR and PYD domain-containing protein 3 (NLRP3) in the kidney exerts its effect not only by the ‘canonical' pathway of IL-1β and IL-18 secretion but also by ‘noncanonical' pathways, such as tumor growth factor-β signaling, epithelial-mesenchymal transition and fibrosis. In both clinical and experimental data, the NLRP3 inflammasome was reported to be involved in the pathogenesis of chronic kidney disease and acute kidney injury. However, the underlying mechanisms are not fully understood. Therapies targeting the activation of the NLRP3 inflammasome or blocking its downstream effectors appear attractive for the pursuit of neuropathy treatments.

Background: The current COVID-19 pandemic has affected almost 17.3 million victims worldwide with mortality of almost 674K. Pregnancy is one of the most susceptible conditions for COVID-19 infection, but limited data is currently available about the clinical characteristics of pregnant women with the disease. Objective; to describe the clinical characteristics, co-morbidities, management, feto-maternal, and neonatal outcome in COVID-19 positive pregnant women. Methodology: A descriptive case series study was conducted in Obs/Gynae dept of Benazir Bhutto Tertiary Care Hospital, Rawalpindi, including all asymptomatic/symptomatic COVID-19 positive pregnant women and clinical suspects (COVID-19 PCR negative women) delivered in our hospital from 01st April 2020 to 31st July 2020. Their medical records were reviewed for clinical characteristics, management, feto-maternal and neonatal outcomes. Continuous variables were expressed in Mean & Range and Categorical variables as number & Percentage. Results: During the study period a total of 17 cases were reviewed. The mean maternal age was 28.94 yrs. Primigravida (07), Multipara (10). Mean gestational age was 37 wks (range; 30-41wks). Presenting symptomatology was varied. Asymptomatic; (29%), COVID-19 specific symptoms; fever & flu (12%), fever&cough (6%), shortness of breath(SOB) alone (6%), fever & SOB(6%) and pregnancy-related manifestations were labour pains (17%), eclampsia(6%), hydrocephalous fetus (6%) and hepatic encephalopathy(6%). The commonest co-morbidity was Hypertensive disorders of pregnancy (24%). Five women (29%) required ICU care. Lower segment caesarean sections(LSCS) (59%), vaginal delivery (41%). Eleven babies delivered with good Apgar score and birth weight. Two were early neonatal deaths (ENND) and 04 were received intra-uterine fetal deaths (IUDs). Fetal demise was associated with strong obstetric risk factors. Out of 13 live-born babies, RT-PCR Covid-19 testing was done in 10 (77%) cases and was negative. One mother was expired due to complications of hepatic encephalopathy, sepsis, and burst abdomen. Conclusion; The clinical course of COVID-19 disease in pregnancy seems to be no different from non-pregnant women. Clinical manifestations are diverse and infection contracted in the third trimester of pregnancy is associated with good feto-maternal and neonatal outcomes.
