IntroductionOcular involvement in leukemia may occur because of direct leukemic infiltration or because of secondary ophthalmic involvement as a result of abnormalities related to blood like anemia, thrombocytopenia, and leukocytosis. In some patients with leukemia, ophthalmic signs can precede the systemic features and can help in early diagnosis of systemic leukemia. Due to the scarcity of data on this topic from Pakistan, we conducted this study to determine the pattern of ocular involvement in patients with leukemia presenting in our settings.MethodsThis cross-sectional study was conducted in a tertiary care hospital of Pakistan over a period of one year. The study comprised of both newly diagnosed and follow-up patients of acute leukemia of age more than 15 years. Patients underwent detailed ophthalmic anterior and dilated posterior segment examination. Patient’s demographic profile, type of leukemia, chemotherapy status, and hematologic findings were also documented.ResultsThere were 97 leukemic patients in the study with 55 (56.7%) males and 42 (43.3%) females. Various ophthalmic manifestations were observed in 47 (48.45%) patients. Forty-two (43.3%) were diagnosed cases with acute lymphocytic leukemia (ALL) and 55 (56.7%) suffered from acute myelogenous leukemia (AML). Ophthalmic manifestations were present in 29 patients of AML (52.7%) and 18 patients of ALL (42.85%). Ocular involvement was significantly more common in newly diagnosed (n=32) as compared with follow-up patients (n=15) (p-value = 0.032). Posterior segment (n=48) was the most common site of ocular involvement (n=48, 49.5%) with retinal hemorrhages seen in 40 patients (41.2%) and papilloedema in seven cases (7.2%). Thirty-three (70.2%) out of 47 patients with ophthalmic manifestations were asymptomatic while 14 (29.8%) had ocular symptoms at the time of initial presentation.ConclusionOphthalmic manifestations were present in about half of the patients with leukemia. Ocular involvement was more prevalent in newly diagnosed cases and in patients with AML.
Alagille syndrome (ALGS) is a rare, debilitating inheritable disease that is associated with refractory pruritus due to chronic cholestasis. The following systemic review and meta-analysis presents the latest evidence for ileal bile acid transport (IBAT) blockers in AGLS patients in order to improve their efficacy. This study adhered to PRISMA 2020 Statement guidelines. A systematic search of PubMed/MEDLINE, Web of Science, Scopus, and the Cochrane library was conducted from inception until 23 October 2022. A combination of the following keywords was used: Alagille syndrome, therapeutics, treatment, therapy. Meta-analytical outcomes included effect directions of end-line changes in serum bile acids (sBAs), Itch Scale scores (ItchRO), Multidimensional Fatigue Scale scores, pediatric quality of life (QL), alanine aminotransferase (ALT), and total bilirubin. A total of 94 patients across four trials were enrolled and received maralixibat, odevixibat, or a placebo. There was a significant reduction in ItchRO scores by 1.8 points, as well as in sBAs by 75.8 μmol/L. Both the Multidimensional Fatigue Scale and Pediatric QL scale were also improved by 11.4 and 8.3 points, respectively. However, ALT levels were raised by 40 U/L. The efficacy of IBAT inhibitors across current trials was noted. Future trials may focus on the optimization of dosing regimens, considering gastrointestinal side effects and drug-induced ALT elevation in AGLS patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
