RESUMO

BACKGROUND: Trichohepatoenteric syndrome (THES) is characterized by neonatal-onset intractable diarrhea. It often requires long-term total parenteral nutrition (TPN). In addition, other characteristic findings of the syndrome include growth retardation, facial dysmorphism, hair abnormalities, various immunological problems and other rare system findings. Two genes and their associated pathogenic variants have been associated with this syndrome: SKIC3 and SKIC2. METHODS AND RESULTS: In this case series, the clinical findings and molecular analysis results of a total of 8 patients from 5 different families who presented with persistent diarrhea and were diagnosed with THES were shared. Pathogenic variants were detected in the SKIC3 gene in 6 of our patients and in the SKIC2 gene in 2 patients. It was planned to compare the clinical findings of our patients with other patients, together with literature data, and to present yet-undefined phenotypic features that may be related to THES. In our case series, in addition to our patients with a novel variant, patient number 2 had a dual phenotype (THES and Spondyloepimetaphyseal dysplasia, sponastrime type) that has not been reported yet. Delay in gross motor skills, mild cognitive impairment, radioulnar synostosis, osteoporosis, nephropathy and cystic lesions (renal and liver) were observed as unreported phenotypic findings. CONCLUSIONS: We are expanding the clinical and molecular repertoire of the syndrome regarding patients diagnosed with THES. We recommend that the NGS (next-generation sequencing) multigene panel should be used as a diagnostic tool in cases with persistent diarrhea.

RESUMO

Candidemia is emerging as a significant concern in children, particularly among those with underlying conditions like malignancies or prematurity. The interpretation of epidemiological data on candidemias and their antifungal resistance plays a vital role in aiding diagnosis and guiding clinicians in treatment decisions. From 2014 to 2021, a retrospective analysis was conducted in Istanbul, Turkey; comparing Candida albicans and non-albicans (NAC) spp in both surviving and deceased groups. Furthermore, an examination of Candida parapsilosis and other species was performed, assessing various clinical and laboratory parameters. Among 93 patients, with a median age of 17 months, C. parapsilosis emerged as the predominant isolated species (44%), followed by C. albicans (34.4%). Resistance to fluconazole, voricanozole, and echinocandins, along with a history of broad-spectrum antibiotic use were found to be significantly higher in the non-albicans Candida group compared to C. albicans group. In the C. parapsilosis group, statistically lower age was identified in comparison to the other groups (P = .018). In addition, high fluconazole and voriconazole resistance was detected in Candida parapsilosis spp. Our study highlights a notable prevalence of C. parapsilosis, particularly in younger children, which is different from similar studies in childhood. This trend may be attributed to the common use of total parenteral nutrition and central venous catheter in gastrointestinal disorders and metabolic diseases. Furthermore, as anticipated, high azole resistance is noted in C. parapsilosis and other non-albicans Candida species. Interestingly, resistance to both amphotericin B and echinocandins within this group has been notably high. It is crucial to emphasize the considerable antifungal resistance seen in C. parapsilosis isolates.
