The Association of Body Mass Index with COVID-19 Complications and Survival Rate at a Tertiary Hospital.

A high body mass index (BMI) is a known risk factor for coronavirus infection in hospitalized patients. Our study examined the association between BMI and complications and the survival rate among COVID-19 patients. This retrospective analysis used data from a tertiary hospital in the Eastern Region of Saudi Arabia during two waves of the COVID-19 pandemic. The study included 600 participants, with the majority being between 41 and 60 years old (41.3%) and men comprising 63.5% of the sample. Approximately 42.5% of patients were obese, and 31.3% were overweight. The results showed that BMI was significantly linked to respiratory diseases (p = 0.013); end-stage renal disease (p = 0.021); and cardiovascular disease (p = 0.003) but not diabetes mellitus (p = 0.064). Death occurred in 10.8% of patients; 33.8% were admitted to the ICU; 13.8% needed mechanical ventilation; and 60.7% had lung infiltration. Obese patients with oxygen saturation levels below 93% were 2.45 times more likely to require mechanical ventilation than those in the normal-weight group. Overweight and obese patients were also more likely to require mechanical ventilation than normal-weight patients, with odds ratios of 3.66 and 2.81, respectively. The BMI categorized was not associated with survival rate in COVID-19-hospitalized patients using Kaplan-Meier survival plots (p = 0.061). However, the BMI categorized was associated with survival rate in COVID-19 ICU patients (p < 0.001). In addition, the overweight showed a statistically significant higher hazard ratio of 2.22 (p = 0.01) compared to normal-weight patients using a Cox regression model. A high BMI was identified as an independent risk factor for reduced oxygen saturation (<93%), the need for mechanical ventilation, lung infiltration, mortality, and longer ICU stays in COVID-19 patients.

Coronavirus disease 2019 (COVID-19) in special groups: A single-center experience in sickle cell disease patients in Saudi Arabia.

BACKGROUND: Sickle cell disease (SCD) is a group of hereditary diseases, inherited as autosomal recessive disorder, which causes mutation in the ß-globin gene. As a result, there is a change in the sixth amino acid from glutamic acid to valine. The affected red blood cell is then prone to polymerization and sickling crisis under conditions of low oxygen tension. One of the major causes of mortality in SCD is acute chest syndrome (ACS). On the other hand, coronavirus disease 2019 (COVID-19) is a pandemic disease that carries significant mortality and morbidity worldwide with unknown outcomes in the affected SCD population. This study was created for that reason. MATERIALS AND METHODS: We report a case series of ten SCD patients who were affected by COVID-19 and required admission between May 1, 2020, and October 30, 2020, at a tertiary care hospital in Dhahran, eastern region of Saudi Arabia. Historical data were obtained retrospectively from electronic records. MS Excel was used for data entry, and SPSS version 23 was used for data analysis. RESULTS: The mean age of the patients involved in the study was 32 years, and the mean duration of symptoms was 5.7 days. None required critical care admission, and there was no mortality. All patients were discharged from hospital in good condition with no requirement of home oxygen. CONCLUSION: Although we expected a fatal outcome of SCD patients affected by COVID-19 infection, our limited case series showed favorable disease behavior and outcome, with a suspicion of underlying unclear protective mechanism from serious complications. However, further studies are required to better understand COVID-19 behavior in SCD patients.

Chronic Neutrophilic Leukemia with Monocytosis.

Chronic neutrophilic leukaemia is a very rare disease with diagnosis based on persistent leucocytosis >25×103/µl and monocytes <1×103/µl. The revised WHO criteria 2016 included CSF3R gene mutations as a diagnostic finding. We report the case of a 77-year-old man who was found to have asymptomatic persistent mature neutrophilic leucocytosis with monocytosis. Molecular study confirmed the presence of a CSF3R gene mutation in the absence of morphological or genetic features of myelodysplasia or other forms of myelodysplastic syndrome. The patient's medical history was significant for coronary artery disease, hypertension, chronic obstructive pulmonary disease, bilateral cystic bronchiectasis, moderate pulmonary hypertension, tuberculosis treated 27 years previously, hypothyroidism, and a thyroid nodule. He had hepatosplenomegaly but no lymphadenopathy, and no other malignancy was seen on computed tomography (CT) scanning. At the time of evaluation, he was free of symptoms and had no evidence of infection or drug-induced leucocytosis. The patient was referred to an oncology centre and treated with hydroxyurea and subsequently azacitidine. However, he developed pancytopenia with bone marrow aplasia. He died with neutropenia sepsis. The presence of persistent monocytosis in this case created a diagnostic dilemma as to whether the disease was a variant of chronic neutrophilic leukaemia or was reactive monocytosis. LEARNING POINTS: The presence of a CSF3R gene mutation is diagnostic for chronic neutrophilic leukaemia (CNL).The monocytosis in this patient might have been a new variant of CNL.

Critical Care COVID-19 Patient with a Picture of Thrombotic Thrombocytopenic Purpura.

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is an uncommon haematological disease which can occur at any age and may present with COVID-19. This case describes a COVID-19 complication associated with a presentation resembling TTP. CASE DESCRIPTION: A 51-year-old man who had received a kidney transplant and was on immunosuppressant medication, was admitted to a critical care unit with severe COVID-19 pneumonia/acute respiratory distress syndrome (ARDS) which required intubation, mechanical ventilation and inotropic support. The course was complicated by the classic pentad of thrombocytopenia, intravascular haemolysis, acute kidney injury, neurological symptoms and fever, which prompted the diagnosis of probable TTP. After five sessions of therapeutic plasma exchange, the patient's general status improved, he was weaned off mechanical ventilation and his renal panel and haemolytic markers normalized. CONCLUSION: TTP is a life-threatening condition which requires urgent management with therapeutic plasma exchange. This case highlights some possible complications of COVID-19 generally and in immunocompromised patients specifically. The potential role of plasma exchange in COVID-19 patients without a positive diagnosis of TTP (the so-called 'TTP resembling presentation') is an area of further research. LEARNING POINTS: COVID-19 can manifest as a picture of thrombotic thrombocytopenic purpura (TTP) which requires therapeutic plasma exchange as in other cases of TTP.Further research is required on the use of therapeutic plasma exchange in severe COVID-19 with cytokine storm.
