Intravenous Immunoglobulins Alone for the Desensitization of Lung Transplant Recipients with Preformed Donor Specific Antibodies and Negative Flow Cytometry Crossmatch.

BACKGROUND: The lack of evidence regarding optimal desensitization strategies for lung transplant candidates with preformed donor specific anti-human leukocyte antigen antibodies (DSAs) has led to varying approaches among centers towards this patient group. Our institution's desensitization protocol for recipients with preformed DSAs and negative flow cytometry crossmatch (FCXM) consists of intravenous immunoglobulin (IVIG) as the sole therapy. The study aimed to determine outcomes using this approach. METHODS: This retrospective study included adults who underwent lung-only transplantation for the first time between January 2015 and March 2022 at a single center. We excluded patients with positive or missing FCXM results. Transplant recipients with any DSA ≥ 1000 MFI on latest testing within three months of transplant were considered DSA-positive, while recipients with DSAs <1000 MFI and those without DSAs were assigned to the low-level/negative group. Graft survival (time to death/retransplantation) and chronic lung allograft dysfunction (CLAD)-free times were compared between groups using Cox proportional hazards models. RESULTS: Thirty-six out of 167 eligible patients (22%) were DSA-positive. At least 50% of preformed DSAs had documented clearance (decrease to <1000 MFI) within the first 6 months of transplant. Multivariable Cox regression analyses did not detect a significantly increased risk of graft failure (aHR 1.04 95%CI 0.55-1.97) or chronic lung allograft dysfunction (aHR 0.71 95%CI 0.34-1.52) in DSA-positive patients compared to patients with low-level/negative DSAs. Incidences of antibody-mediated rejection (p = 1.00) and serious thromboembolic events (p = 0.63) did not differ between study groups. CONCLUSION: We describe a single-center experience of administering IVIG alone to lung transplant recipients with preformed DSAs and negative FCXM. Further studies are required to confirm the efficacy of this strategy against other protocols.

Employment and occupational safety among patients with seizure disorders - findings from a tertiary hospital in Saudi Arabia.

OBJECTIVE: Observational studies suggest that persons with seizure disorders are socially disadvantaged compared to the general population. There are scarce reports in the literature on the prevalence of employment and occupational safety among patients with seizure disorders in Saudi Arabia. We aimed to describe the occupational statuses of patients with seizure disorders and determine factors associated with unemployment. METHODS: This was a cross-sectional study conducted at King Faisal Specialist Hospital and Research Center in Riyadh, Saudi Arabia. Five-hundred-and-forty patients with known seizure disorders or epilepsy who attended neurology and neurosurgery outpatient clinics between January and November 2018 completed a semi-structured questionnaire delivered by interview. RESULTS: Forty-four percent of participants were unemployed (27% of males and 64% of females). Fifteen percent of currently or previously employed participants reported that they had formerly resigned from their job due to their seizure disorder, most commonly as a result of their own fears or concerns. Almost half of the participants reported that their employer made arrangements in the workplace for their seizure disorder, while 18% reported that they did not disclose their diagnosis. Gender, age, and highest educational level were associated with employment status and reason for unemployment. Patients with seizures secondary to trauma were less than half as likely to be employed compared to other participants (aOR = 0.45 95%CI 0.21-0.97, p = 0.042). Holding a driving license increased the odds of being employed (aOR = 2.68 95%CI 1.32-5.46, p = 0.007). Participants on 4 or more antiepileptic medications were more likely to report not being well enough to work. SIGNIFICANCE: Patients with seizure disorders are at increased risk of unemployment, even though many desire work. Unemployment is linked to social factors rather than disease-specific characteristics. Employers in Saudi Arabia generally accommodate patients in the workplace; however, individuals should further be empowered with information on safety in the workplace and their rights to employment.

Voriconazole-Induced Hepatotoxicity Resolved after Switching to Amphotericin B in Fusarium dimerum Central Line-Associated Bloodstream Infection.

BACKGROUND Fusarium spp. is a rare cause of opportunistic life-threatening fungal infections. It has a remarkably high resistance profile with few effective antifungal agents, mostly limited to voriconazole and liposomal amphotericin B. Drug-induced liver injury (DILI) by 1 of these 2 antifungal agents further complicates the management of these infections. CASE REPORT A 38-year-old woman with short bowel syndrome presented to the hospital with concerns of abdominal pain and loose stools. An abdominal CT was negative for inflammatory or ischemic bowel disease, and there was no evidence of liver disease. She tested positive for SARS-CoV-2 and required transfer to the ICU due to hypotension requiring fluid resuscitation and vasopressors. On day 43 of her admission, the patient developed a low-grade fever, for which she underwent central-line and peripheral-blood cultures that were positive for Fusarium dimerum. The central line was removed and i.v. voriconazole started. After 3 days of treatment, the patient's liver enzymes rose abruptly. Voriconazole was discontinued and replaced with liposomal amphotericin B, and the liver enzymes improved significantly. The patient completed 14 days of therapy and was discharged from the hospital. CONCLUSIONS This is a case of F. dimerum infection followed by DILI from voriconazole treatment. Her infection was resolved after switching to liposomal amphotericin B, with improvement in liver enzymes on day 1 after discontinuing voriconazole. This observation demonstrates that altering antifungal classes may be an appropriate strategy when confronted with DILI.

Preference of sweeteners among Saudi diabetes patients from a tertiary health care centre in Riyadh, Saudi Arabia.

BACKGROUND: Choice of sweetening options can influence glyceamic control among patients with diabetes. This study aims to investigate the preference of added sweeteners for Saudi patients with diabetes, factors associated with the choice of sweeteners and the attitude of the patients towards the use of artificial sweeteners. METHODS: This was a cross-sectional study conducted at King Saud University Medical City in Riyadh, Saudi Arabia and targeting Saudi patients with type 2 diabetes mellitus. Data was collected via personal interviews accessing medical records of interviewed patients. Patients were asked about consumption of sweeteners and types of consumed soft drinks on daily basis. Bi-variate analysis of the associations between choice of sweeteners and patients characteristics was performed and followed by binary logistic regression to adjust for potential confounders such as age, gender, and education level. RESULTS: A total of 302 Saudi diabetic patients were recruited in this investigation. Among this sample, frequency of patients reporting weekly consumption of white sugar was the highest (57%), followed by honey (26%) and artificial sweeteners (12% for powder form and 10.5% for tablets). Consumption of white sugar was significantly more frequent among patients with higher level of Body Mass Index (BMI) (P value < 0.05). The frequency of using honey was higher among females while consumption of either sugared or low calorie soft drinks was significantly higher among male patients (P values < 0.05). Upon asking the patients about their attitude towards artificial sweeteners, only 25% of the sample agreed that their use can aid in reduction of caloric intake while 35% of the sample agreed that artificial sweeteners can be harmful to the body. CONCLUSIONS: Among this sample of type 2 diabetes patients, the frequency of white sugar and honey use as a sweetening option is high. These findings generate the need for further research to investigate the effectiveness of health education and nutritional advice among diabetes patients attending similar clinical settings in Saudi Arabia.
