Background Lymphopenia is one of features that helps identify patients with severe Covid-19. This retrospectively study analyzed the association of lymphopenia with the severity of COVID-19 infection, determinate the predictive factors of lymphopenia and the significance of mortality in patient with lymphopenia. Methods This retrospective study included patients diagnosed with Covid-19 and admitted to intensive care unit of our university hospital center From Mars 1st 2020, to December 31st , 2020. Results In this study, 589 patients were included, a group had lymphopenia with 357 cases (60.06%) and the non-lymphopenia group with 232 cases (39.4%). The median age of our patients having lymphopenia was 65 years (56–76). Hypertension and diabetes were noted in the majority of patients with lymphopenia than in the non-lymphopenia group. Lymphopenia was strongly correlated to the inflammatory biomarkers of COVID-19 and were significant. A significant correlation was found between lymphopenia group and CT scan. Lymphopenia was observed as an indicator of prolonged duration of hospitalization but was not significant. Conclusion Analytical data from this retrospective study shows the importance in the association between lymphopenia and the severity of COVID-19 infection, hence the need for dynamic monitoring of the number of lymphocytes on admission and during hospitalization of these patients.

Posterior reversible encephalopathy (PRES) is a rare but a serious disease that affects the central nervous system. PRES is responsible for various but nonspecific neurological symptoms, including confusion, coma, and seizures as well as visual disturbances. Diagnosis is made using cerebral MRI which typically shows at the early stage, bilateral symmetrical parietooccipital hyperintensities on T2 and fluid-attenuated inversion recovery (FLAIR) sequences. Case study. In this article, we base our research on a case study that includes, as a population sample, a 9-year-old boy who suffers from an acute postinfectious glomerulonephritis and arterial hypertension. Two days before diagnosis, he developed confusion with generalized tonic-clonic attacks. His blood pressure was 180/80 mmHg. A cerebral computed tomography made in emergency showed cerebral edema. It was supplemented by magnetic resonance imaging which revealed cortical and posterior cortical lesions which appear as hypointense on T1 and hyperintense on T2 and Flair. An MRI control was performed 40 days later which shows a clear improvement of the occipital lesions. PRES is a radioclinical syndrome characterized by the association of variable neurological signs which reversibility is conditioned by the early diagnosis and the correction of the contributing factors.

Background COVID-19 is a new disease that appeared in December 2019. Millions of people have been infected and died from this infection. Until today, the pathophysiology and treatment of this infection remain unknown, but a lot of studies are trying to solve the mystery. The trail of inflammation remains the most convincing, especially the Interleukin 6 (IL-6) which could play an important role in a reaction cascade leading to a cytokine storm. According to studies, although few in number, the Tociluzimab (TCZ), which is an anti-IL6, could prevent or even suppress this storm, leading to a less severe clinical state of the disease and a faster recovery. This could decrease the use of oxygen, avoid the risk of intubation and mortality. Patients and methods This single-center retrospective observational case review brought together 557 COVID-19 seriously ill patients (pulmonary involvement> 25% + SatO 2 AA <90%) admitted to the intensive care unit of our university hospital from March 1 st , 2020 to February 28 th , 2021. They were divided into 2 groups a Tociluzimab group (TCZ group) and a Non Tociluzimab group (NON TCZ) to facilitate the comparison. The aim of the study was to compare the length of hospital stay, the use of mechanical ventilation and the mortality in the TCZ group versus the NON TCZ group. Results The average age of our patients was 62,05 years (±13.51) and 62.61 years (±16.33) respectively in the TCZ versus NON TCZ group. 76 (76%) were men while 24 were women (24%) in the TCZ group; and there was 313 (68.49%) men and 144 (31.51%) women in the NON TCZ group. Their average BMI was 28 kg/m2 (±4.52) in the TCZ group versus 27.89 kg/m2 (±4.73) in the NON TCZ group. Among them, the TCZ group included 38 (38%) diabetic patients, 38 hypertensive (38%), 12 heart disease (12%) and 2 chronic renal failure (2%), while the NON TCZ group regrouped 35 (7.65%) diabetics, 33 (7.22%) hypertensive, 12 heart disease (2.67%), and 5 chronic renal failure (1.09%) patients. The mean time to consultation of patients was almost similar in the two groups: 8.86 (±7,28) days for TCZ and 8.83 (±7,03) days for NON TCZ group. The mean length of ICU hospital stay was 9 days (4,94) for the TCZ group and 8,75 days (4,73) for the other one. The saturation at admission was at 74.92% (10.45) for the TCZ group ranging from 40% to 92%, and at 73,56% for the NON TCZ group. Lung damage from COVID-19 was extensive in 12%, severe in 32%, and critical in 56% of TCZ group enrolled cases. Meanwhile it was extensive in 23.63%, severe in 41,35%, and critical in 35,01% of the NON TCZ group. The biological findings found average of white blood cells at 12256/12082 e/mm 3 , lymphocytes at 761/842 e/mm 3 , CRP at 181/199 mg/L, ferritin at 1747/528 μg/L, and fibrinogen at 6.92/6.27 g/L for the TCZ group versus NON TCZ group.

Introduction Acute pancreatitis (AP) is considered one of the potentially rare complications of severe hypertriglyceridemia (HTG). Multiple treatment modalities have been suggested for patients with HTG-AP, such as permanent removal of TG by plasmapheresis, the use of insulin and heparin to enhance lipoprotein lipase activity and fibrate therapy, but the data remains limited. Case management we reported a case of 33-year-old women admitted for HTG-induced PA (HTG-AP). The patient had hypertriglyceridemia for 7 years under fibrate therapy as a medical history. On admission to our intensive care unit, his triglyceride level was 1060 mg/dl and the lipase level was 298 IU/L. An abdominal CT scan revealed stage E AP. The patient was treated with a low dose insulin infusion (0.05 unit/kg/h) with heparin and 5-day course of plasmapheresis, Fibrate therapy was maintained. His triglycerides went down to 130.9 mg/dl and she was discharged. Conclusion Early recognition of severe HTG can prevent progression to multiples diseases such as acute pancreatitis, can facilitate appropriate or even aggressive treatment to minimize complications of this.
