RESUMO
BACKGROUND: Overt eosinophilic peritonitis (EP) is a relatively uncommon complication of peritoneal dialysis (PD), although not rare. Here we reported a case of EP relieved after changing dialysate. CASE PRESENTATION: A 28-year old male patient developed cloudy PD effluents within the first month after PD started. Cytological study of PD effluents showed elevated white blood cells and polynuclear cells. Bacteria culture of PD effluents repeated for several times were all negative, and no pathogen was found by metagenomics next generation sequencing (mNGS). Antibiotic therapy for 28-day was ineffective. Based on these and increased eosinophils in peritoneal fluid, he was finally diagnosed as EP. PD dialysate was changed (consists of the same buffer agent and electrolytes, but is packed in bags that do not contain PVC), and the patient's PD effluent became clear. Of note, EP did not relapse 5 months later when the patient started to use the former PD solution again. CONCLUSION: Although PD effluent turbidity almost always represents infectious peritonitis, there are other differential diagnoses including EP. For patients with cloudy fluid accompanied by mild symptoms who do not response to antibiotic therapy, it is reasonable to consider the possibility of this disease. EP tends to heal spontaneously, however, antihistamines or glucocorticoids are required sometimes to avoid catheter obstruction. For patients with no obvious incentives, replacement of dialysate may be useful.

Porphyromonas gingivalis, a gram-negative oral anaerobe among more than more than 500 bacterial species that colonizing the oral cavity, is involved in the pathogenesis and prototypic polybacterial consortium of periodontitis. It is mainly found in oral infections and rarely present in other organ diseases. Here, we describe a 43-year-old man with underlying diabetes who developed hematogenous disseminated severe pneumonia after P. gingivalis had invaded the blood. Next-generation sequencing of early alveolar lavage fluid and blood samples confirmed the diagnosis. The patient's lung infection improved after targeted antimicrobial treatment. He was successfully weaned from ventilatory support and transferred to the general ward. This case illustrates bacterial entry into the bloodstream of a patient with diabetes who had periodontal disease but did not maintain oral hygiene, leading to severe pneumonia. Periodontal disease is often ignored by the public, and it is difficult for critical care physicians to link severe pneumonia with periodontal disease. Thus, this case represents an important warning to critical care clinicians.

OBJECTIVE: To investigate the relationship between antiviral restriction factor Sterile Alpha Motif and Histidine-Aspartic acid domain-containing protein 1 (SAMHD1) expression and T cell activation, furthermore, identifying objective indexes of lung-spleen deficiency symptom pattern. METHODS: We assessed the profile of T lymphocyte subsets, characteristics of SAMHD1 and human leukocyte antigen DR (HLA-DR) expression in lung-spleen deficiency patients. At the same time, people living with human immunodeficiency virus / acquired immune deficiency syndrome (HIV/AIDS) (PLWHA) without obvious clinical symptoms and healthy donors in this area were used as controls. RESULTS: Immunohematologic indexes lower CD4 count, lower CD4/CD8 ratio and higher SAMHD1 level were found in lung-spleen deficiency patients. Furthermore, we demonstrated a positive relationship between SAMHD1 and HLA-DR level as well as with interferon factor in lung-spleen deficiency syndrome and patients without obvious clinical signs and symptoms groups. CONCLUSIONS: These data indicated the positive relationship between SAMHD1 and T cell activation which further elucidated the role of SAMHD1 in cellular immune response. Furthermore, combination of T lymphocyte subsets counts and SAMHD1 level may be used as clinical and biological reference basis for the differentiation and diagnosis of HIV / AIDS traditional Chinese medicine syndromes.
