Bordetella bronchiseptica infections in patients with HIV/AIDS: A case report and review of the literature.

RATIONALE: Bordetella bronchiseptica is a common cause of upper respiratory tract infections in domesticated dogs and cats and a rare zoonotic pathogen in immunocompromised humans. With increasing numbers of people acquiring pets and spending time with them in confined spaces due to COVID-19 lockdowns, it is important to be aware of adverse health consequences brought about by this interaction. We present a case of B bronchiseptica pneumonia in a patient with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and review key characteristics of an additional 30 cases of B bronchiseptica infections in 29 patients with HIV/AIDS that were identified by literature review. PATIENT CONCERNS: A 61-year-old male with HIV/AIDS who was not on antiretroviral therapy and had advanced immunosuppression with a CD4+ T-lymphocyte count of 3 cells/µL sought medical attention for multiple somatic issues including subjective fevers, shortness of breath, and intermittent chest pain. DIAGNOSIS: Computed tomography of the chest identified bilateral nodular opacities in the lower lobes with scattered areas of ground glass opacities. B bronchiseptica was identified in sputum culture by mass spectrometry followed by supplementary biochemical testing. INTERVENTIONS: Empiric broad-spectrum antibiotics were initiated and changed to levofloxacin after susceptibility testing was completed. OUTCOMES: The patient was discharged after symptomatic improvement with levofloxacin. LESSONS: Pneumonia with interstitial infiltrates in the setting of advanced CD4 lymphocyte depletion is the most common clinical syndrome caused by B bronchiseptica in patients with HIV/AIDS, and may be accompanied by sepsis. Advanced immune suppression, as well as chronic medical conditions, for example, alcoholism, diabetes, and renal failure that compromise host defenses are also commonly found in cases of B bronchiseptica infection in patients who do not have HIV infection. Reported animal contact among patients was not universal. Isolates were susceptible to aminoglycosides, carbapenems, fluoroquinolones, but typically resistant to most cephalosporins.

Vancomycin resistant Enterococci and its associated factors among HIV infected patients on anti-retroviral therapy in Ethiopia.

BACKGROUND: The emergence of vancomycin resistant Enterococci (VRE) has alarmed the global community due to its tendency for colonization of the gastrointestinal tract. Human Immunodeficiency Virus (HIV) patients are colonized by vancomycin resistant Enterococci than other groups. The aim of this study was to determine the incidence of vancomycin resistant Enterococci and its associated factors among HIV infected patients on Anti-Retroviral Therapy (ART). METHODS: Institution based cross sectional study was conducted among HIV infected patients on ART at from June 1 to August 30, 2020. Socio-demographic and clinical data were collected by pre-tested structured questionnaire. Stool sample was collected and processed by standard microbiological techniques. Kirby Bauer Disc diffusion method was used to perform antimicrobial susceptibility testing. Data were entered by Epi data version 4.6.0.2 and analyzed by SPSS version 25. Bivariable and multivariable logistic regression model was used to analyze the association between dependent and independent variables. P-values in the multivariable analysis, adjusted odds ratio (AOR) and 95% confidence interval (CI) were used to determine the strength of association. P-value ≤0.05 was considered as significant. RESULTS: Enterococci spp was isolated on 123/200 (61.50%) patients. Among these isolates, the incidence of vancomycin resistant Enterococci was 11.4% [95% CI: (6.0-17.0)]. Antimicrobial susceptibility patterns against Enterococci showed highest rate of resistance to ampicillin (69.9%). Multidrug resistances were observed in 49.59% of Enterococci isolates. Study participants who had prior antibioticexposurer more than two weeks [AOR = 7.35; 95% CI: (1.2144.64)] and hospitalization for the last six months [AOR = 5.68; 95% CI: (1.09 29.74)] were significantly associated with vancomycin resistant Enterococci. CONCLUSIONS: In our study high incidence of vancomycin resistant Enterococci was found. Previous exposure to antibiotics for more than two weeks and hospitalization for more than six months were significantly associated with vancomycin resistant Enterococci. The isolated Enterococci had variable degrees of resistance to commonly prescribed antibiotics. Therefore, periodic surveillance on antimicrobial resistance pattern, adhering to rational use of antibiotics and implementing infection prevention protocols may reduce colonization by VRE.

Impact of COVID-19 in patients with concurrent co-infections: A systematic review and meta-analyses.

The burden and impact of secondary superadded infections in critically ill coronavirus disease 2019 (COVID-19) patients is widely acknowledged. However, there is a dearth of information regarding the impact of COVID-19 in patients with tuberculosis, HIV, chronic hepatitis, and other concurrent infections. This review was conducted to evaluate the consequence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in patients with concurrent co-infections based on the publications reported to date. An extensive comprehensive screening was conducted using electronic databases up to 3rd September 2020 after obtaining registration with PROSPERO (CRD420202064800). The observational studies or interventional studies in English, evaluating the impact of SARS-CoV-2 in patients with concurrent infections are included for the meta-analyses. Our search retrieved 20 studies, with a total of 205,702 patients. Patients with tuberculosis (RR = 2.10; 95% CI, 1.75-2.51; I2 = 0%), influenza (RR = 2.04; 95% CI, 0.15-28.25, I2 = 99%) have an increased risk of mortality during a co-infection with SARS-CoV-2. No significant impact is found in people living with HIV (RR = 0.99; 95% CI, 0.82-1.19; I2 = 30%), Chronic hepatitis (RR = 1.15; 95% CI, 0.73-1.81; I2 = 10%). Several countries (Brazil, Paraguay, Argentina, Peru, Colombia, and Singapore) are on the verge of a dengue co epidemic (cumulative 878,496 and 5,028,380 cases of dengue and COVID-19 respectively). The impact of COVID-19 in patients of concurrent infections with either tuberculosis or influenza is detrimental. The clinical outcomes of COVID-19 in HIV or chronic hepatitis patients are comparable to COVID-19 patients without these concurrent infections.

Case Report: Coronavirus Disease and Pulmonary Tuberculosis in Patients with Human Immunodeficiency Virus: Report of Two Cases.

Coinfection of SARS-CoV-2/Mycobacterium tuberculosis (MTB) in patients with HIV/AIDS has not been previously reported. Here, we present two cases of coinfection of SARS-CoV-2 and MTB in patients with HIV. The first case is a 39-year-old patient who was admitted with a 7-day history of fever, myalgia, headache, and cough. The second patient is a 43-year-old man who had a 1-month history of cough with hemoptoic sputum, evolving to mild respiratory distress in the last 7 days. Both patients already had pulmonary tuberculosis and subsequently developed SARS-CoV-2 infection during the 2020 pandemic. Nonadherence to antiretroviral treatment may have been a factor in the clinical worsening of the patients.

Case Report: COVID-19 Recovery from Triple Infection with Mycobacterium tuberculosis, HIV, and SARS-CoV-2.

COVID-19, designated as SARS-CoV-2, has caused millions of infections worldwide, including in patients with concomitant infections. Here, we report two unusual cases of patients with triple infections of SARS-CoV-2, Mycobacterium tuberculosis, and HIV. Both cases were confirmed through microbiological and immunological studies. The acute respiratory phase in both patients was treated with supplemental oxygen. Antituberculosis and antiretroviral therapies were started simultaneously. In 2 weeks, both patients demonstrated clinical improvement and recovery from COVID-19. Our findings suggest that even in cases of triple infection, clinical management together with respiratory therapy contributes to patient survival.
