Background: Cancer patients, as a highly vulnerable population, are receiving a great deal of attention in the current crisis of coronavirus 2019 (COVID-19). To date, shreds of evidence are not sufficient to the description of COVID-19 outcomes in patients with cancer. This study was performed to evaluate the demographic and clinical characteristics and subsequent outcomes of COVID-19 in cancer patients. Materials and Methods: A hospital-based study was conducted involving 66 cancer patients with a confirmed diagnosis of COVID-19 from January 15, 2020, to December 21, 2020, in Isfahan, Iran. The clinical information was collected by interview and medical records. The statistical analyses were performed to describe categorical variables as well as mean, standard deviation, median, and the interquartile range for quantitative variables. Results: In our study, 66 cancer patients with confirmed COVID-19 (age: 17–97 years; 50% female) were included. Leukemia and bone marrow cancer with a frequency of 25.7% were the most common types of cancer among them. Cancer patients mostly complained of fever, cough and fatigue, and shortness of breath. Among 76.9% of patients discharged from the hospital with relative recovery, 23% died; the most common cause of death was acute respiratory distress syndrome. Age, gender, and type of cancer did not affect cancer mortality. COVID-19 had no potential effect to increase the risk of side effects of anticancer therapies. Conclusion: The results of our studies revealed that cancer is an important risk factor for the higher rate of mortality in patients with COVID-19. These findings could help physicians for the management, treatment, and supportive care of COVID-19 cancer patients.

Background: Familial hypercholesterolemia (FH) leads to elevated low-density lipoprotein cholesterol (LDL-C) levels in plasma. Mutations of its related gene; apolipoprotein B (APOB) is seen in about two percent of the patient with FH. Thyroid disease is usually part of the exclusion criteria for the detection of FH which alters the lipid profile. We evaluated mutations in the APOB gene in patients with high LDL-C levels. Materials and Methods: Patients aged between 2 and 80 years with at least one LDL-C level of more than 190 mg/dl were selected (120 patients) from Isfahan Laboratories. Blood samples were obtained from all patients. Genomic DNA was extracted. Primer sequences were designed by Oligo 7.60 to amplify the desired 844 bp region of exon 26 of the APOB gene containing R3500Q and R3500W variants associated with FH. Results: Overall, two patients showed a heterozygous form of a common pathogenic variant in exon 26 named c. 10579 C > T (R3500W, cDNA.10707), and one patient was hypothyroidism. We also recognized another nonpathognomonic variant c. 10913G > A (rs1801701, cDNA.11041) in 13 patients, two of them were hypothyroidism. Conclusion: This study for the first time shows the coexistence of APOB mutation in hypothyroidism, which emphasis screening of patients with hypothyroid for FH detection.
