Objective To explore the efficacy and adverse reactions of diminishing scheme of cefaclor sustained re-lease tablets in the treatment of recurrent urinary tract infection(RUTI).Methods 60 RUTI patients in a hospital were divided into treatment group(n=30)and control group (n=30),patients in treatment group were treated with diminishing scheme of cefaclor sustained release tablets,patients in control group were treated with diminishing scheme of levofloxacin tablets,clinical therapeutic efficacy and adverse reactions of two groups were observed. Results The curative rate in treatment group was higher than control group ([80.00%,n =24]vs [53.33%,n =16])(χ2 =4.80,P =0.028).The incidence of RUTI in treatment group was lower than control group ([6.67%,n=2]vs [26.67%,n=8])(χ2 =4.32,P =0.038).Incidence of adverse reactions in treatment group was lower than control group (16.67% vs 50.00%)(χ2 =7.50,P =0.006).Conclusion The diminishing scheme of cefaclor sus-tained release tablets in the treatment of RUTI has good curative efficacy,low recurrence rate,fewer adverse reac-tions,and can be used for the treatment of recurrence of RUTI.

Objective To explore the characteristics of opportunistic infections(OIs)in HIV-infected indi-viduals with suboptimal immune reconstitution after ART treatment so as to provide a reference for preventing and managing HIV infections.Methods The clinical data including opportunistic infections specifically were acquired from 112 HIV-infected individuals with suboptimal immune reconstitution from the outpatient department of Wuming Hospital,Guangxi Medical University.The impact of baseline CD4+T lymphocyte counts on the incidence,type,and mixed infection rates of the opportunistic infections were analyzed.Results The opportunistic infection rate among the 112 HIV-infected individuals with suboptimal immune reconstitution was 42.86%,among which fungal infections were the most commonly seen.The opportunistic infection rate of the patients with a baseline of CD4+T lymphocyte counts≤50/μL was significantly higher than that of the patients with a baseline of CD4+T lymphocyte counts>50/μL,and there was no significant difference in the type of opportunistic infections as well as the rate of mixed infections.Conclusion HIV-infected people with suboptimal immune reconstitution in Guangxi are susceptible to HIV OIs.Among them,the group with a baseline CD4+ T lymphocyte counts≤50/μL has a higher rate of OIs,mainly fungal infections.

Objective:To analyze the relationship between killer cell immunoglobulin-like receptor ( KIR) genes and immune reconstitution failure in human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) patients after anti-retroviral therapy (ART). Methods:HIV/AIDS patients receiving ART for ≥1 year who attended the AIDS outpatient clinics of Wuming Hospital of Guangxi Medical University and People′s Hospital of Mashan from May 2007 to December 2019 were included. Patients were divided into immune reconstitution failure group and full immune reconstitution group. Polymerase chain reaction with sequence specific primers (PCR-SSP) was used to detect KIR genotypes in all subjects, and the genotype frequency (PF) of 16 KIR genotypes was calculated. Statistical analysis was conducted using chi-square test. Multivariate logistic regression was used to analyze the relationship between KIR genotypes and immune reconstitution failure.Results:There were 102 patients with HIV/AIDS, including 44 immunological non-responders and 58 immunological responders. The PF of KIR2 DL5 in immune reconstitution failure group was 59.09%(26/44), which was higher than 36.21%(21/58) in full immune reconstitution group, and the difference was statistically significant ( χ2=5.27, P=0.022). Multivariate logistics regression analysis showed that KIR2 DL5 was associated with immune reconstitution failure when adjusted for age and baseline CD4 + T cell count. Positive expression of KIR2 DL5 may be a risk factor for immune reconstitution failure (adjusted odds ratio (a OR)=2.431, 95% confidence interval 1.012 to 5.844, P=0.047). Conclusions:Positive expression of KIR2 DL5 may be related to immune reconstitution failure in HIV/AIDS patients after ART.
