Abstract
Pseudoxanthoma elasticum (PXE) is characterized by low levels of inorganic pyrophosphate (PPi) and a high activity of tissue-nonspecific alkaline phosphatase (TNAP). Lansoprazole is a partial inhibitor of TNAP. The aim was to investigate whether lansoprazole increases plasma PPi levels in subjects with PXE. We conducted a 2 × 2 randomized, double-blind, placebo-controlled crossover trial in patients with PXE. Patients were allocated 30 mg/day of lansoprazole or a placebo in two sequences of 8 weeks. The primary outcome was the differences in plasma PPi levels between the placebo and lansoprazole phases. 29 patients were included in the study. There were eight drop-outs due to the pandemic lockdown after the first visit and one due to gastric intolerance, so twenty patients completed the trial. A generalized linear mixed model was used to evaluate the effect of lansoprazole. Overall, lansoprazole increased plasma PPi levels from 0.34 ± 0.10 µM to 0.41 ± 0.16 µM (p = 0.0302), with no statistically significant changes in TNAP activity. There were no important adverse events. 30 mg/day of lansoprazole was able to significantly increase plasma PPi in patients with PXE; despite this, the study should be replicated with a large number of participants in a multicenter trial, with a clinical end point as the primary outcome.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) is progressive immune-mediated fibrotic condition characterised by a tendency to form tumefactive lesions in different organs and by elevated IgG4 serum concentrations. Urological manifestations are rare and normally occur together with other systemic affections. Myelodysplastic syndromes (MDS) are hematopoietic stem cell neoplasms, with different subtypes based on the type of blood cells involved. MDS can be associated with other pathologies or medical treatments. We present an uncommon case of testicular manifestation associated with myelodysplastic syndrome here.
