Emerging evidence suggests an association between certain metabolites produced by gut microbiota and potential alterations in the severity of infection. Trimethylamine N-oxide (TMAO) is a waste metabolite generated by gut microbes from dietary choline and betaine. Evidence Acquisition: Several investigations have indicated an association between serum TMAO concentrations and the development of inflammation and thrombosis. Trimethylamine N-oxide, produced by the gut microbiome in a state of dysbiosis, upregulates various molecular mechanisms, such as the nuclear factor kappa (NF-kB) molecular pathway, and promotes the expression of scavenger receptors (SRs) on the surfaces of macrophages, leading to foam cell formation and inflammation. High levels of TMAO have been shown to induce the expression of pro-inflammatory cytokines like tumor necrosis factor-alpha (TNF-α) and interleukin 1β (IL-1β) while reducing the expression of anti-inflammatory cytokines such as interleukin-10 (IL-10). Additionally, gut-derived TMAO enhances platelet aggregation and adhesion to collagen, increasing the risk of thrombosis. Conclusions: Understanding the association between gut microbiome compositions such as gut TMAO and their effects on SARS-CoV-19 infection progression helps to control disease severity. In this review, we presented a hypothesis that the gut TMAO has the potential to increase COVID-19 disease severity.","PeriodicalId":51793,"journal":{"name":"Archives of Clinical Infectious Diseases","volume":"23 6","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139125894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the geographical and social situation of the border cities of Sistan and Baluchestan province, this study was conducted to evaluate the prevalence of the Chikungunya infection in the southeastern cities of Iran using enzyme-linked immunosorbent assay (ELISA). Methods: In this cross-sectional study, 203 participants were randomly selected from 4 southeastern cities of Iran (Taftan, Sib-and-Suran, Mehrestan, and Mirjaveh). First, sociodemographic and clinical data were gathered by a questionnaire. Next, individual blood samples were taken, and ELISA was performed to measure anti-CHIKV IgG levels. Results: The participants’ ages ranged from 6 - 50 years, with 27.5% of them being 21 - 30 years old. Based on the results, 17 cases (8.37%) had episodes of fever, 13 (6.40%) had fever and arthralgia, and 12 (5.91%) had a history of hospitalization. In addition, there were 3 positive samples (1.48%). One of these people lived in Mehrestan, and two lived in Sib-and-Suran. The incidence of the virus infection was significantly higher in the age groups of 41 - 50 and 21 - 30 years old (P = 0.046). The likelihood of CHIKV infection was higher in farmers, independent contractors, and housewives (P = 0.001). Moreover, the most indicative clinical symptoms were the simultaneous occurrence of fever and arthralgia. Conclusions: The findings of this study confirm the presence of CHIKV in Sistan and Baluchestan. The geographic distribution of the positive samples indicates that other factors are involved in the spread of infection besides the tropical climate and proximity to Pakistan.","PeriodicalId":51793,"journal":{"name":"Archives of Clinical Infectious Diseases","volume":" 5","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139136253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: This study aimed to determine the concentration and correlation of maternal and cord blood anti-SARS-CoV-2 IgG antibodies in Iranian seropositive women. In this preliminary study, attempts were also made to assess the effects of some variables on the transplacental transfer efficiency. Methods: From September 2021 to November 2021, pregnant women presenting to Kamali Hospital in Karaj, Iran, were enrolled in this monocentric study. The maternal and neonatal demographic characteristics were collected. The maternal and cord blood spike protein-specific antibody levels, measured at delivery (119 paired samples), were evaluated by the enzyme-linked immunosorbent assay (ELISA). Results: Based on the transplacental antibody transfer ratios, the participants were divided into 2 groups: Transfer ratio ≤ 1 (n = 53) and transfer ratio > 1 (n = 66). The results revealed that anti-SARS-CoV-2 IgG antibodies were transferred across the placenta in all seropositive pregnant Iranian women, and a significant correlation was found between maternal and cord blood-specific IgG antibody levels (r = 0.9646; P < 0.05). A relatively efficient transplacental transfer ratio was observed in Iranian seropositive women (transfer ratio > 1 in 66 out of 119 individuals; 55.46%). Although there were significant differences in the transplacental transfer ratio regarding the neonatal birth weight and maternal body mass index (BMI), more extensive investigations with a larger sample size are needed to confirm the significant association of these variables with the transplacental transfer efficiency of specific SARS-CoV-2 IgG antibodies.

It is caused by Cryptococcus neoformans and the C. gattii species complex. The primary predisposing factor is HIV, but it can also be observed in conditions such as immunodeficiency, sarcoidosis, liver disease, solid organ transplantation, and steroid treatment. Case Presentation: This report discusses a 61-year-old man with a medical history of liver transplantation, open-heart surgery, diabetes, hypertension, and previous cryptococcal meningitis. He had been receiving antifungals and was discharged in good condition to continue maintenance treatment at home. During his latest admission, he was hospitalized to investigate weakness and suspicious ulcerated skin lesions refractory to glucantime through biopsy. Two days after hospitalization and before receiving the biopsy result, the patient gradually developed lethargy, headache, and nausea. Laboratory examinations of cerebrospinal fluid (CSF) and skin biopsies revealed encapsulated yeast cells identified as Cryptococcus neoformans using culture media and the PCR method. The patient died shortly after receiving liposomal amphotericin B and oral fluconazole.

Providing medical care to patients with both COVID-19 and advanced HIV disease presents specific challenges due to the simultaneous lung damage caused by the SARS-CoV-2 virus and opportunistic pathogens. Objectives: This study aimed to explain the rationale behind recommending HIV screening for patients with severe COVID-19. Methods: A single-center retrospective cohort study was conducted using electronic medical records from a specialized hospital in Moscow that focused on coinfection with HIV/COVID-19. Among the 3,563 patients hospitalized in the relevant departments during the study period, 408 patients were included based on the inclusion/exclusion criteria. Out of the 408 patients with both COVID-19 and advanced HIV disease, 132 individuals were newly diagnosed with HIV infection, while 276 individuals had a previously established HIV diagnosis. Results: The mortality rate in the group of patients with COVID-19 and advanced HIV disease was 31.7% (95% CI, 27.3 - 36.3%). Among patients with COVID-19 and newly diagnosed advanced HIV disease, the mortality rate was 45.5% (95% CI, 37.1 - 54%), while in the group of patients with previously diagnosed advanced HIV disease, the mortality rate was 25% (95% CI, 20.2 - 30.4%). The proportion of individuals with critical CT-4 lung disease in the first group was 32.3% compared to 9.4% in the second group (P < 0.001). The median CD4+ count was 20 cells/µL in the first group compared with 88 cells/µL in the second group (P < 0.001). Conclusions: The presence of pneumocystis pneumonia increased the risk of death by 2.51 times in patients with COVID-19 and newly diagnosed advanced HIV disease. Additionally, Kaposi's sarcoma increased the risk of death by 1.31 times in the same patient group.

Methods: In this cross-sectional study at Imam Hossein Hospital's Rheumatology Clinic (Iran), we investigated 72 SLE patients in remission who received the Sinopharm BIBP inactivated COVID-19 vaccine. Their post-vaccination status was monitored for 3 months using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) checklist by an internal medicine specialist. Results: Fourteen patients (19.44%) experienced symptom flare-ups after vaccination. The most common symptoms were arthritis (64.29%) and skin rash (21.43%). Age, sex, organ involvement, and treatment regimen did not significantly differ between those with and without symptom recurrence (P > 0.05). The second vaccine dose led to more flare-ups compared to the first dose (12.12% vs. 8.33%, P < 0.001). However, the severity of symptom recurrence, measured by the SLEDAI-2K score (P = 0.763), and the interval from vaccination to symptom recurrence (P = 0.075) did not significantly differ between the 2 groups. Except for 2 patients, none of the participants required hospitalization, and flare-up symptoms were effectively managed by prednisolone dosage adjustments. For these 2 patients, the treatment regimen was changed, and the steroid dose was increased; one of them was admitted to the hospital, and the other one was managed on an outpatient basis. Conclusions: The incidence of flare-ups in SLE patients in remission following COVID-19 vaccination with Sinopharm BIBP vaccine was low; most of them were mild and did not require hospitalization, except for 1 patient who was hospitalized after the first dose of vaccination and received rituximab due to vasculitis flare.

However, insights into the molecular attributes of S. aureus collected from patients with chronic otitis media have yet to be reported in Iran. Objectives: The objective of this study was to assess the molecular characteristics of S. aureus isolated from patients with chronic otitis media. Methods: A total of 55 S. aureus strains retrieved from patients with chronic otitis media were analyzed by the disk diffusion method and polymerase chain reaction (PCR) to identify the nucA gene. Isolates were genetically classified using the coagulase typing method. S. aureus protein A (spa) typing, staphylococcal cassette chromosome mec (SCCmec) typing, and multilocus sequence typing (MLST) were performed on isolates with resistance to specific antibiotics. Results: Overall, out of 55 S. aureus isolates, resistance to mupirocin, fusidic acid, and tigecycline was identified in 12.7%, 5.4%, and 3.6% of isolates, respectively. Fusidic acid-resistant isolates belonged to ST5-SCCmecII/t002/coaII. Two tigecycline-resistant isolates belonged to CC8/ST239-SCCmecIII/t234/coaVIII. One positive mecC isolate belonged to the CC/ST130-SCCmecXI/t843/coaIII clone.
