Quality of Life Evaluation in Saudi Arabian Pediatric Patients with Primary Immunodeficiency Diseases Receiving 20% Subcutaneous IgG Infusions at Home.

BACKGROUND AND AIMS: Subcutaneous immunoglobulin (SCIG) home infusion is widely used as an alternative to intravenous immunoglobulin (IVIG). This study aimed to determine the quality of life (QoL) of patients with primary immunodeficiency (PID) after switching to home-based SCIG. METHODS: In this prospective open-label single-center study, QoL was determined using the validated Arabic version of the Child Health Questionnaire at baseline and 3 and 6 months after switching from IVIG to SCIG. RESULTS: Twenty-four patients were recruited from July 2018 to August 2021, including 14 females and 10 males. The median age of the patients was 5 years (range, 0-14 years). The patients' diagnoses included severe combined immunodeficiency, combined immunodeficiency, agammaglobulinemia, Omenn syndrome, immunodysregulation, hyper-IgE syndrome, common variable immunodeficiency, and bare lymphocyte syndrome. The median duration on IVIG before inclusion was 40 months (range, 5-125 months). The QoL score showed a significant improvement in the patients' global health at 3 and 6 months compared with those at baseline and a significant improvement in the patients' general health at 3 and 6 months compared with that at baseline. The mean baseline serum IgG trough level was 8.8 ± 2.1 g/L. The mean serum IgG level was significantly higher on SCIG at both 3 and 6 months (11.7 ± 2.3 and 11.7 ± 2.5 g/L, respectively). CONCLUSIONS: This is the first study involving an Arab population to show improvement in the QoL of patients with PID after switching from hospital-based IVIG to home-based 20% SCIG.

Assessment of foetal risk associated with 93 non-US-FDA approved medications during pregnancy.

Health care practitioners utilize the United States-Food and Drug Administration (US-FDA) pregnancy categorization (A, B, C, D, X) for making decision on the appropriateness of certain medications during pregnancy. Many non US-FDA approved medications are registered and marketed in Saudi Arabia. However, these medications do not have an assigned pregnancy risk categorization like those approved in the US. The objective of this review is to evaluate, report, and categorize the foetal risk associated with non-US-FDA approved medications registered by the Saudi Food and Drug Authority (S-FDA) according to the US-FDA pregnancy risk categorization system. We identified 109 non-US-FDA approved medications in the Saudi National Formulary (SNF) as of October 2007. We searched for data on functional or anatomical birth defects or embryocidal-associated risk using different databases and references. An algorithm for risk assessment was used to determine a pregnancy risk category for each medication. Out of 93 eligible medications, 73% were assigned category risk C, 10 medications (11%) were assigned category risk D, and 12 medications (13%) were assigned category risk B. Only three medications were judged to be safe during pregnancy based on the available evidence and were assigned category risk A. Inconsistencies in defining and reporting the foetal risk category among different drug regulatory authorities could create confusion and affect prescribing. We believe that standardization and inclusion of this information in the medication package insert is extremely important to all health care practitioners.
