Analysis of blood type for SARS-CoV-2 and correlation for disease acquisition in various sociodemographic groups including women of childbearing age.

BACKGROUND: Multiple studies have occurred to determine if a patient's blood type, Rhesus factor (Rh), and sociodemographic attributes contribute to contracting SARS-CoV-2. True association remains unknown. METHODS: Inclusion criteria included in-patients who were tested for SARS-CoV-2 with blood type assessed. Study endpoints combined ABO, Rh and all-cause inpatient mortality (ACIM) with testing positivity. Pregnancy status was one of several secondary endpoints evaluated. A logistic regression analysis was used to estimate association. RESULTS: Of the 27,662 patients who met inclusion criteria, Type A blood was associated with increased positivity [1.01 (1.0-1.21), P = .03]. Type B [1.10 (0.99-1.23), P = .08] and AB [0.98 (0.81-1.19), P = .84] showed no association. When evaluating ACIM, type A [1.18 (0.91-1.52), P = .22], B [1.13 (0.82- 1.56), P = .480], and AB [1.06 (0.62-1.81), P = .839] were not associated with increased mortality. The female subgroup was less likely to test positive [0.88 (0.82-0.986), P = .002]. Black patients demonstrated a higher likelihood of positivity when compared to White [1.96 (1.79-2.14), P < .001]. Non-pregnant women exhibited a 2.5 times greater likelihood of testing positive [2.49 (2.04-3.04), P < .001]. CONCLUSIONS: This study confirms results of previous research which showed SARS-Co-V-2 positivity related to blood type. It also confirms more recent research demonstrating inequities related to acquisition of SARS-CoV-2 for certain sociodemographic groups. Larger studies are warranted to confirm and further explore novel pregnancy findings.

Three-class antiretroviral resistance in a patient with acute HIV-1 infection.

Antiretroviral resistance in treatment-naïve patients with HIV-1 infection is on the rise in both resource-rich and resource-poor countries. We report a case of three-class primary antiretroviral resistance detected by a genotypic assay in a 19-year-old woman with acute HIV-1 infection. Her risk factor for HIV acquisition was unprotected sexual intercourse with a HIV-positive man. At diagnosis, her HIV-1 RNA level was 730,376 copies per milliliter, and 2 weeks later her CD4+ cell count was 465 cells/mm(3). The patient's antiretroviral therapy was chosen based on the genotype of the source patient. Subsequent analysis of our patient's virus revealed an identical genotype to that of the source patient. The patient tolerated therapy well and continues to be virologically suppressed after 1 year of therapy. Her current CD4+ cell count is 537 cells/mm(3) and HIV-1 RNA is less than 400 copies per milliliter. This case supports the current recommendations from several HIV therapy guidelines to perform resistance testing in patients with acute HIV-1 infection.

Potential clindamycin resistance in clindamycin-susceptible, erythromycin-resistant Staphylococcus aureus: report of a clinical failure.

The erm gene product confers clindamycin resistance on Staphylococcus aureus. We report a clindamycin clinical failure where resistance developed on therapy in a D-test-positive strain. D tests of 91 clindamycin-susceptible, erythromycin-resistant S. aureus isolates showed that 68% of methicillin-susceptible and 12.3% of methicillin-resistant S. aureus strains were D-test positive.

Cladophialophora bantiana brain abscess in a solid-organ transplant recipient: case report and review of the literature.

Cerebral phaeohyphomycosis caused by Cladophialophora bantiana is a rare disease. We describe a heart and bilateral lung transplant recipient who was unsuccessfully treated for a C. bantiana brain abscess. This report compares the present case to those of other solid-organ transplant recipients with the same infection and to those of patients who did not receive transplants.
