AI Article Synopsis
- The study aimed to assess the link between extremely high alkaline phosphatase (ALKP) levels (over 1000 U/L) and negative outcomes in pregnancy.
- Researchers conducted a retrospective analysis of 11 cases from a medical center and added 10 more from previous literature, noting complications such as preterm delivery and gestational diabetes occurring in some patients.
- The findings indicate that elevated ALKP levels in most cases were of placental origin and suggest a correlation with adverse perinatal outcomes, marking one of the largest case series on this subject to date.
Article Abstract
Objectives: To evaluate the association between extremely elevated alkaline phosphatase (ALKP) levels (above 1000 U/L) and adverse perinatal outcome.
Methods: A retrospective case series of all parturients with extremely elevated ALKP levels taken throughout pregnancy at a single university-affiliated medical center (2010-2018). Demographics and medical data were retrieved. Following literature review, previously reported similar cases were added to the cohort. We report perinatal outcome of our cohort as well as literature review.
Results: During study period 11 parturients with high ALKP were identified. Ten more cases were retrieved from PubMed search. Overall, median ALKP levels were 1880 (range 1052-4488 U/L). Reasons for evaluation were mostly nonspecific symptoms (pruritus, headache, abdominal pain) or routine obstetrical evaluation. In 10/12 (83%) cases, elevated ALKP levels were of placental origin; the rest had osteal origin. Median gestational age at delivery was 38 (range 35-41); four (19%) women had preterm delivery. Six patients (29%) had gestational diabetes mellitus and six (29%) had hypertensive disorders. Histopathology of the placenta was available in eight cases: three normal histology (38%) and five with different non-specific pathologies.
Conclusions: We report the largest case series of extremely elevated levels of ALKP in pregnancy thus far. Our data suggest association with adverse perinatal outcome.

The active metabolite of vitamin D3, calcitriol (1,25D), is widely recognised for its direct anti-proliferative and pro-differentiation effects. However, 1,25D is calcaemic, which restricts its clinical use for cancer treatment. Non-calcaemic agonists of the vitamin D receptor (VDR) could be better candidates for cancer treatment.

Background/objectives: X-linked hypophosphataemic rickets (XLH) represents the most frequent type of rickets from genetic origin, it is caused by mutations on the gene. The main clinical manifestations are short stature and bone deformities. Phenotype variation is observed at the intrafamily and interfamily level.

Objective: To explore the clinical characteristics and risk factors for adverse outcomes in patients with Sjögren's Syndrome-associated pulmonary arterial hypertension (SS-PAH).
Methods: A retrospective analysis was conducted on SS-PAH patients diagnosed by right heart catheterization (RHC) between March 2013 and March 2024 across four Chinese medical centers. Patients were categorized into primary SS-PAH (pSS-PAH) and overlap SS-PAH, based on the presence of additional autoimmune diseases.

Hypophosphatasia (HPP) is a congenital bone disease caused by tissue-nonspecific mutations in the alkaline phosphatase gene. It is classified into six types: severe perinatal, benign prenatal, infantile, pediatric, adult, and odonto. HPP with femoral hypoplasia on fetal ultrasonography, seizures, or early loss of primary teeth can be easily diagnosed.
