Response to Lisinopril in Patients with Sickle Cell Anemia and Proteinuria.

Proteinuria is a manifestation of sickle cell anemia (SCA)-related renal disease and is a risk factor of renal impairment. Angiotensin-converting enzyme (ACE) inhibitors have benefits, but their role in SCA remains undefined. This study aimed to assess the role of lisinopril, an ACE inhibitor, in reducing proteinuria in SCA patients.

Evidence-based Management of Major Bleeding in Patients Receiving Direct Oral Anticoagulants: An Updated Narrative Review on the Role of Specific Reversal Agents.

The indications of direct oral anticoagulants (DOACs) have expanded over the past 15 years. DOACs are effective and safe oral anticoagulants associated with lower bleeding risks and mortality than vitamin K antagonists. However, DOAC users are prone to a considerable bleeding risk, which can occur at critical sites or lead to severe life-threatening conditions.

Bleeding Diathesis as the Initial Presentation of Chronic Myeloid Leukemia: A Case Series.

Chronic myelogenous leukemia, or CML, is another name for chronic myeloid leukemia (CML), a cancer type that starts in certain bone marrow blood-forming cells. The primary initiator of granulocytic proliferation in CML, a myeloproliferative malignancy, is the BCR-ABL1 fusion protein or Philadelphia chromosome. CML is classified into three stages: chronic, accelerated, and blast.

Hemostatic profile detailing in apparent VWD cases: A cross sectional study.

The von willebrand disease (vWD) accounts to be one of the most common hereditary bleeding ailment that amounts its incidence to almost 1.5% of normal population. It is mostly associated with a defect in primary hemostasis as well as secondary defect in coagulation factor VIII as diagnosis of vwd happened to be challenging with earlier diagnostic criteria's.

Factor XII deficiency in asymptomatic Saudi population: A retrospective cohort study.

Factor XII (FXII) deficiency is a rare genetic blood disorder. It can lead to a higher risk of developing deep vein thrombosis or acquired thrombotic disorders than the general population. This retrospective study evaluated patients who opted for surgery and were found to have abnormal clotting profiles and clotting factors on preoperative routine blood.

Evaluating the novel parameters for assessing the LAA function and thrombus formation with nonvalvular atrial fibrillation.

The dysfunction of left atrial appendage (LAA) is prone to form thrombus when atrial fibrillation (AF) sustained more than 48 h. Traditional 2D-TEE (transesophageal echocardiography) can not accurate evaluate the function of LAA. The purpose of this study is to analyze the relationship of LAA function parameters and thrombus formation in patients with non-valvular atrial fibrillation (NVAF) by real-time three-dimensional transesophageal echocardiography (RT-3D-TEE).

The Role of Reticulocyte Hemoglobin Content for the Diagnosis of Functional Iron Deficiency in Hemodialyzed patients.

The effectiveness of reticulocyte hemoglobin content (CHr) had been reported to detect early functional iron deficiency especially among Chronic kidney disease (CKD) patients. CHr is more superior to classic biochemical indices in reflecting transient iron-deficiency status, therefore improving diagnosis and treatment. This study was conducted to determine the sensitivity of CHr in the diagnosis of functional iron deficiency (FID) in hemodialyzed patients.

The clinical and laboratory manifestations profile of antiphospholipid syndrome among Saudi Arabia population: Examining the applicability of Sapporo criteria.

Antiphospholipid syndrome is a organized autoimmune disease presented with vascular thrombosis and pregnancy morbidity. The Sapporo classification criteria of APS were revised in 2006 and are used as the main diagnosis guideline, which validity as standard measurements is still in debate. This study observe the clinical and laboratory indices of APS among Saudi patients.

Features and incidence of thromboembolic disease: A comparative study between high and low altitude dwellers in Saudi Arabia.

To estimate and compare the incidence of thromboembolic disease among patients who are clinically suspected for VTE among high and low altitude dwellers in Saudi Arabia. A prospective study conducted over two years (2011-2013) conducted in two different geographical areas in Saudi Arabia; Abha City and Riyadh City. Patients clinically suspected with deep vein thrombosis and pulmonary embolism was recruited to the study.

Thromboprophylaxis after bariatric surgery.

Background: Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is a known cause of morbidity and mortality after bariatric surgery. However, the data concerning appropriate thromboprophylaxis after bariatric surgery is uncertain. The objective of this study was to evaluate the efficacy and safety of extended duration thromboprophylaxis in post-bariatric surgery patients.

Secondary hemosiderosis presented by porphyria cutanea tarda in a kidney dialysis patient: A case report.

A 68-year-old woman with chronic kidney disease receiving dialysis and iron supplementation presented to our hospital with painful blisters, fragile skin, and changes to skin pigmentation on the dorsal side of both upper and lower limbs. Skin biopsy findings and an increase in urine porphyrins confirmed the diagnosis of porphyria cutanea tarda. Upon examination, extremely high serum ferritin levels (6000 µg/L) suggested iron overload.
