Beyond Dermatological Findings: Multisystem Involvement in Prolidase Deficiency.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Prolidase deficiency is a metabolic and immunological disorder that is inherited in an autosomal recessive manner. In prolidase deficiency, a broad spectrum of differences is observed in patients, ranging from asymptomatic to multisystem involvement. There is scarce information in the literature on the atypical features and immunophenotypes of this disease. Aim of this study is to present 4 new cases to provide information on the rare features of the disease and to raise awareness. Materials and Methods: This study included 4 female patients with prolidase deficiency. Their demographic, clinical, and immunologic characteristics were obtained from their medical records. Results: There were 4 female patients (P1-P4), with a mean age of 18.5 years (min-max: 10-29) and a mean age of symptom onset of 6.9 years (min-max: 0.04-27). The main presenting complaints of the patients were skin lesions (100%), dysmorphic features (100%), neurodevelopmental delay (100%), frequent infections (100%), and prolonged diarrhea (50%). P2 had diffuse large B-cell lymphoma, resulting in early death. Interestingly, P1 and P2 experienced opportunistic infections such as cytomegalovirus, Epstein-Barr virus, and Pneumocystis jirovecii. Three patients (75%) had lymphopenia. Two patients had elevated IgE levels. Lymphocyte subgroup analysis showed an inverted CD4/CD8 ratio in all patients. In patients P1 and P2, the percentages of naive T cells and recent thymic emigrants were reduced, suggesting combined immune deficiency at the time of diagnosis. CD19+ B cells were also low in P1 and P2. Metabolic evaluations revealed low prolidase enzyme activity in P1 and P2. Conclusion: Beyond the well-known classical dermatological findings, the presence of recurrent opportunistic infections, gastrointestinal involvement, malignancy, and flow cytometry findings suggestive of combined immunodeficiency indicate that the diagnosis of prolidase deficiency may be underestimated. Knowing the atypical and rare presentations will facilitate diagnosis and treatment of affected patients.
