OBJECTIVE:
To summarize the clinical features and management of two brothers affected with X-linked inhibitor of apoptosis protein (XIAP) deficiency.
METHODS:
This study retrospectively analyzed the clinical presentations, treatment, and follow-up of two brothers with XIAP deficiency diagnosed at Shanghai Children's Hospital in 2020, and summarized similar cases recorded in databases such as PubMed, Wanfang, Chinese Medical Association Journals, and WIP from January 2006 to November 2024. This study was approved by the Medical Ethics Committee of our hospital (Ethics No.: 2025R128-E01).
RESULTS:
Patient 1 was the younger brother, who presented at 8 years of age with growth retardation, folliculitis, erythema nodosum, and perineal abscess. Sequencing revealed that he has carried a hemizygous c.566T>C (p.Leu189Pro) variant of the XIAP gene, which was inherited from his mother. He was allergic to infliximab treatment and underwent allogeneic stem cell transplantation (HSCT) in January 2021. During a follow-up of 3 years and 10 months post-transplantation, he showed no gastrointestinal symptoms and had a good outcome. Patient 2 was the elder brother, who presented at 10 years and 6 months of age with growth retardation, rash, and anal fistula. Genetic testing revealed the same variant. He was treated with oral azathioprine but did not have regular follow-ups. At 14-years-and-6-months of age, he had developed severe gastrointestinal infection and hemophagocytic lymphohistiocytosis, which was alleviated after treatment with antibiotics, glucocorticoids, immunoglobulin, and rituximab. He is currently being prepared for HSCT. A total of 13 publications were retrieved, which involved 64 patients from 23 families, with 23 different variants identified. The main clinical manifestations included splenomegaly (34 cases, 53.1%), hemophagocytic lymphohistiocytosis (27 cases, 42.2%), and inflammatory bowel disease or colitis (20 cases, 31.8%). There were significant phenotypic differences among patients from the same family. Thirteen patients (20.3%) underwent HSCT, with a survival rate of 61.5%.
CONCLUSION
For male children with early onset, poor treatment response, especially those with unexplained splenomegaly and IBD-like symptoms, early genetic testing is recommended. HSCT is a safe and effective treatment for XIAP deficiency. For patients with developmental delay, early onset, and severe IBD phenotype, early transplantation is recommended.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Objective To investigate whether PKCβ inhibitor can alleviate RIRI by regulating macrophage phenotype.Methods Rats in the renal ischemia-reperfusion injury(RIRI)model group underwent right nephrec-tomy followed by a 60-minute clamping of the left renal pedicle.In the experimental group(Inhibitor+RIRI),PKCβ inhibitors were administered orally one day prior to surgery.All rats were euthanized 24 hours post-surgery for the collection of blood and left kidney samples.Renal function,tissue morphology,and the expression levels of renal tubular injury marker KIM-1,renal papilla injury marker RPA-1,macrophage subtype markers,and inflammatory factors were evaluated.Results PKCβ inhibitors alleviated renal ischemia-reperfusion injury in rats.PAS staining revealed marked tubular damage in kidney sections from the RIRI group,whereas kidney inflammatory cell infiltra-tion and renal tubular injury scores were significantly reduced in the Inhibitor+RIRI group following PKCβ inhibitor treatment(all P<0.05).The expression levels of Cr,BUN,KIM-1,and RPA-1 were markedly elevated in the RIRI group compared to the Sham and Inhibitor+RIRI groups(all P<0.05).After PKCβ inhibitor intervention,the expression levels of Cr,BUN,KIM-1,and RPA-1 were significantly decreased in the Inhibitor+RIRI group relative to the RIRI group(all P<0.05).Protein expression levels of iNOS,IL-2,and CD197 in the kidney tissue of the RIRI group were significantly higher than those in the Sham and Inhibitor+RIRI groups(all P<0.05).Compared with the RIRI group,the protein expression levels of iNOS,IL-12,and CD197 were significantly reduced in the Inhibitor+RIRI group following PKC β inhibitor intervention(all P<0.05).Additionally,the protein expression levels of Dectin-1,ARG-1,and CD163 were significantly higher in the Inhibitor+RIRI group than in the RIRI and Sham groups after PKCβ inhibitor intervention(all P<0.05).Conclusions PKCβ inhibitors can mitigate renal dysfunction,renal tubular injury,and the expression of injury markers in the renal tubules and renal papilla follow-ing ischemia-reperfusion.Additionally,PKCβ inhibitors play a role in modulating macrophage subtypes by reducing M1 macrophages and promoting polarization to M2,which leads to a decrease in pro-inflammatory factors and an increase in anti-inflammatory factors,ultimately facilitating kidney repair.
