Lung involvement in accident victims: report of three cases

Lungs are target organ for damage during accidents and contribute significantly to the mortality of the victims. Here we present three different types of accidental injury to the lungs leading to respiratory failure and their varied presentations

Bilateral morgagni hernia in a case of Weill-Marchesani syndrome-a rare association

Morgagni hernia constitutes only about 2% of all diaphragmatic hernias and bilateral Morgagni hernia is extremely rare. Here we present a 75 year old female patient with morphometric features of Weill-Marchesani syndrome who has bilateral Morgagni hernia. This association is reported for the first time in literature

Soluble ACE2 and angiotensin II levels are modulated in hypertensive COVID-19 patients treated with different antihypertension drugs.

This study examines the effect of antihypertensive drugs on ACE2 and Angiotensin II levels in hypertensive COVID-19 patients. Hypertension is a common comorbidity among severe COVID-19 patients. ACE2 expression can be modulated by antihypertensive drugs such as ACEis and ARBs, which may affect COVID-19's prognosis. BB and CCB reduce mortality, according to some evidence. Their effect on circulating levels of ACE2 and angiotensin II, as well as the severity of COVID-19, is less well studied. The clinical data were collected from 200 patients in four different antihypertensive medication classes (ACEi, ARB, BB, and CCB). Angiotensin II and ACE2 levels were determined using standard ELISA kits. ACE2, angiotensin II, and other clinical indices were evaluated by linear regression models. Patients on ACEi ( = 57), ARB ( = 68), BB ( = 15), or CCB ( = 30) in this study had mild ( = 76), moderate ( = 76), or severe ( = 52) COVID-19. ACE2 levels were higher in COVID-19 patients with severe disease ( = 0.04) than mild ( = 0.07) and moderate ( = 0.007). The length of hospital stay is correlated with ACE2 levels ( = 0.3,  = 0.003). Angiotensin II levels decreased with severity ( = 0.04). Higher ACE2 levels are associated with higher CRP and D-dimer levels. Elevated Angiotensin II was associated with low levels of CRP, D-dimer, and troponin. ACE2 levels increase with disease severity in patients taking an ARB ( = 0.01), patients taking ACEi, the degree of disease severity was associated with a decrease in angiotensin II. BB patients had the lowest disease severity. We found different levels of soluble ACE2, and angiotensin II are observed among COVID-19 patients taking different antihypertensive medications and exhibiting varying levels of disease severity. COVID-19 severity increases with elevated ACE2 levels and lower angiotensin II levels indicating that BB treatment reduces severity regardless of levels of ACE2 and angiotensin II.Open Access funding is provided by the Qatar National Library.
