Abstract
Introduction Reactivation of pulmonary tuberculosis is a prevalent concomitant infection and cause for mortality in burns patients in Sub-Saharan Africa. First line laboratory diagnostic studies for pulmonary tuberculosis are often negative in these patients and if relied on, result in high mortality. The purpose of this report is to share our experience with a novel protocol of empiric treatment of clinically suspected pulmonary tuberculosis in severely burned patients with negative GeneXpert tests in a tertiary burns centre and to present a brief literature review on the topic. Methods A retrospective chart review of all patients, who sustained thermal injury with an inhalation component, with negative GeneXpert tests who were treated empirically for pulmonary tuberculosis over a five-year period (2015-2020) was performed. Additionally, a literature search was performed on Medline (PubMed), Cochrane and Google Scholar databases. Results Over the five-year period, 20 patients with suspected pulmonary tuberculosis and severe burns requiring ventilation were managed according to the protocol and all survived to discharge. The literature search identified six factors that explain the consequence of pulmonary tuberculosis in severely burned patients and provide a hypothesis for the negative laboratory studies encountered. Conclusion There was an improved outcome for patients with the clinical diagnosis of reactivation of pulmonary tuberculosis when they were started on empirical pulmonary tuberculosis treatment. There are several potential mechanisms that can contribute to reactivation of pulmonary tuberculosis in susceptible severely burned patients. The GeneXpert test should not be relied upon in these patients for a diagnosis, but rather all other clinical evidence should inform management. Lay Summary From the current literature evidence most patients who have severe burns complicated by a secondary infection known as pulmonary (lung) tuberculosis, die as a result. The purpose of this report is to share our experience with treatment of pulmonary tuberculosis during a five-year period, from 2015 to 2020, in a specialized adult tertiary burn center. Severely burned patients who were suspected of having pulmonary tuberculosis and received treatment despite having negative laboratory tests for pulmonary tuberculosis, had a better survival rate than expected. A brief literature review on the topic of pulmonary tuberculosis and severe burns was done to investigate causes for reactivation of pulmonary tuberculosis and negative laboratory studies in these patients.The literature search identified the following factors that can potentially affect the reactivation of pulmonary tuberculosis in severely burned patients: decreased immune system; secondary infections; low blood albumin(protein) levels; decreased clearance of bacteria from the airways, the development of pulmonary tuberculosis biofilms (capsules that protect the bacteria from chemicals and antibiotics) and the role of a fat molecule called phosphatidylinositol mannoside in pulmonary tuberculosis.In conclusion, the pulmonary tuberculosis test should not be relied upon in these patients, but rather all the clinical evidence such X-ray changes in association with difficulty to wean the patient off the ventilator should be used to inform treatment choice.

Determination of lymphocytes surface markers in patients with thermal burns and the influence of burn size on mononuclear cell subsets. Med J Islam Repub Iran 2017; 31:38. [PMID: 29445667 PMCID: PMC5804437 DOI: 10.14196/mjiri.31.38] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2016] [Indexed: 12/27/2022] Open
Abstract
Background: Thermal burn injuries impair the host defence system. Hence, in the present study, we aimed at investigating the changes in the number and phenotype of peripheral blood lymphocyte populations (T, B, and natural killer cells) and their subpopulations in patients with thermal burns and determining the relationships with different sizes of total body surface area (TBSA). Methods: Blood samples from 67 patients, admitted to Motahary Burn Center in Tehran, with burns from 30% to more than 70% TBSA were collected on Days 3 and 7 postburn. Lymphocytes and their subpopulations were identified by monoclonal antibodies. The cells were analyzed using flow cytometry. The results were compared with healthy controls. Results: In this study, 3 and 7 days after burn injury, the percentages of CD3+, CD4+ and CD8+ lymphocyte significantly decreased, CD4+/CD8+ ratios were below the normal range, and CD19+ (B cells) significantly increased. No significant difference was obtained in the mean percentage of CD16+ (NK cells) between Days 3 and 7 postburn. Patients with burns of 30% TBSA or greater (>70%) had a significant reduction in CD3+, CD4+ and CD8+ ( T cells) numbers up to 7 days compared with 3 days after burn injury. Patients with 30% to >70 % TBSA burn failed to show any significant changes in CD4+/CD8+ ratio as well as CD16+ (NK cells) 3 to 7 days after burn. In patients with burns more than 30% to>70% TBSA, CD19+ (B cells) number changes were found to be complicated after 3 and 7 days. Conclusion: The results of this study suggest that alterations of immune cell surface markers and TBSA% can reflect postburn lymphocyte activation.

Abstract
The aim of the present study was to determine the prevalence of human immunodeficiency virus (HIV) infection among acute burn patients and its impacts on patient's outcomes in an Iranian burn care hospital. A cross-sectional study was conducted in a tertiary burn care hospital in Iran, retrospectively reviewing the data records of all patients admitted between February 2011 and February 2012. The HIV status of all the patients was assessed in relation to clinical outcomes and the patient's prognosis. A total of 969 patients were included in this study. Five patients (0·5%) were HIV positive, and all of them were male. Mean burn area was significantly larger in HIV-positive patients than the healthy group (P < 0·05). HIV-positive patients had a longer period of hospitalisation than HIV-negative patients (23·2 ± 16·3 versus 13·1 ± 14·6, P = 0·008). Nonetheless, the average number of procedures and the mortality rate did not significantly differ between the study groups (P > 0·05). Comparison of age, sex and burn extent between HIV-positive patients and HIV-negative cases also revealed similar results. Prevalence of HIV infection among our burn population was 0·5%; thus, HIV status may be related with more extensive injuries and longer hospital stays.

Abstract
In South Africa, burns are a major public health problem responsible for significant morbidity and long-term physical disability. This is, in part, due to a significant proportion of the urban population living in poorly constructed, combustible accommodation. The presence of co-morbid diseases such as diabetes and malignancy in patients with burns has been associated with a poorer outcome. The impact of other diseases such as HIV has yet to be defined. A retrospective data collection study analysed the 221 patients admitted to Tygerberg Hospital Burns Unit in 2011 and the first six months of 2013. Using hospital records, patient demographic data was collected alongside burn agent, ICU admission, complications, and patient outcome in terms of length of stay and mortality. The most common burn agent was hot liquid (45.7%). A significant proportion of patients were subject to intentional attacks (34.3%). Shack fires and flame accounted cumulatively for 85% of total inhalational burns, the highest rates of admission to ICU (85.5%), the highest rate of complications, as well as 92.3% of all total fatalities. HIV+ patients had a higher mortality (13.3% vs 5%, p=0.22) and a higher complication rate (46.7% vs 30%, p=0.21). There was no difference in length of stay between the HIV+ and HIV- cohort (12days vs. 15.5 days, p=0.916). Burns are a significant yet preventable cause of mortality and morbidity. The rising number of shack fires, responsible for extensive burns and resultant mortality is concerning and indicates urgent attention and action. HIV complicates the recovery from burn and is responsible for an increased rate of in hospital mortality.

Abstract
HIV has a significant impact on surgery in Africa. Its’ influence has spanned a period of about 30 years. In the 1980s' Africa experienced a rise in the national prevalence of HIV spreading across East Africa through Southern Africa, and reaching peak prevalence in the Southern African region. These prevalence levels have affected four key areas of surgical practice; namely patient care, practice of surgery, surgical pathologies, the practitioner and more recently prevention. The surgical patient is more likely to be HIV positive in Africa, than elsewhere in the world. The patients are also more likely to have co infection with Hepatitis C or B and are unlikely to be aware of his or her HIV status. Surgical patients are also more likely to have impaired liver and renal function at the time of presentation. Therefore, HIV has affected the pattern of surgical pathologies, by influencing disease presentation, diagnosis, management and outcomes. It has also influenced the surgeon by increasing occupational risk and management of that risk. Recently in an ironic change of roles, surgery has impacted HIV prevention through the role of male circumcision as a significant tool in HIV prevention, which has traditionally focused on behavioural interventions. The story of surgery and HIV continues to unfold on the continent. Ultimately presenting a challenge which requires innovation, dedication and hard work in the already resource limited environments of Africa.

Abstract
IMPORTANCE Antiretroviral therapy (ART) has converted human immunodeficiency virus (HIV) infection into a chronic condition, and patients now undergo a variety of surgical procedures, but current surgical outcomes are inadequately characterized. OBJECTIVE To compare 30-day postoperative mortality in patients with HIV infection receiving ART with the rates in uninfected individuals. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of nationwide electronic medical record data from the US Veterans Health Administration Healthcare System, October 1, 1996, to September 30, 2010. Common inpatient surgical procedures were grouped using the Healthcare Cost and Utilization Project Clinical Classification System to match HIV-infected and uninfected patients in a 1:2 ratio. Data on 1641 patients with HIV infection receiving combination ART who were undergoing inpatient surgery were compared with data on 3282 procedure-matched, uninfected comparators. Poisson regression models of 30-day postoperative mortality were adjusted for procedure year, age, Charlson Comorbidity Index score, hemoglobin level, albumin level, HIV infection, CD4 cell count, and HIV-1 RNA level. MAIN OUTCOMES AND MEASURES All-cause 30-day postoperative mortality. RESULTS The most common procedures in both groups were cholecystectomy (10.5%), hip arthroplasty (10.5%), spine surgery (9.8%), herniorrhaphy (7.4%), and coronary artery bypass grafting (7.0%). In patients with HIV infection, CD4 cell distributions were 80.0% with 200/μL or more, 16.3% with 50/μL to 199/μL, and 3.7% with less than 50/μL; 74.1% of patients with HIV infection had undetectable HIV-1 RNA. Human immunodeficiency virus infection was associated with higher 30-day postoperative mortality compared with the mortality in uninfected patients (3.4% [56 patients]) vs 1.6% [53]); incidence rate ratio [IRR], 2.11; 95% CI, 1.41-3.17; P < .001). CD4 cell count was inversely associated with mortality, but HIV-1 RNA provided no additional information. After adjustment, patients with HIV infection had increased mortality compared with uninfected patients at all CD4 cell count strata (≥500/μL: IRR, 1.92; 95% CI, 1.02-3.60; P = .04; 200-499/μL: IRR, 1.89; 95% CI, 1.20-2.98; P = .01; 50-199/μL: IRR, 2.66; 95% CI, 1.29-5.47; P = .01; and <50/μL: IRR, 6.21; 95% CI, 3.55-10.85; P < .001). Hypoalbuminemia (IRR, 4.35; 95% CI, 2.78-6.81; P < .001) and age in decades (IRR, 1.47; 95% CI, 1.23-1.76; P < .001) were also strongly associated with mortality. CONCLUSIONS AND RELEVANCE Current postoperative mortality rates among individuals with HIV infection who are receiving ART are low and are influenced as much by hypoalbuminemia and age as by CD4 cell status. Human immunodeficiency virus infection and CD4 cell count are only 2 of many factors associated with surgical outcomes that should be incorporated into surgical decision making.

Abstract
OBJECTIVE Burns are important preventable causes of morbidity and mortality, with a disproportionate incidence in sub-Saharan Africa. The management of these injuries in sub-Saharan Africa is a challenge because of multiple other competing problems such as infectious diseases (HIV/AIDS, tuberculosis and malaria), terrorist acts and political instability. There is little investment in preventive measures, pre-hospital, in-hospital and post-discharge care of burns, resulting in high numbers of burns, high morbidity and mortality. Lack of data that can be used in legislation and policy formulation is a major hindrance in highlighting the problem of burns in this sub-region. METHODS An online search of publications on burns from sub-Saharan countries was performed. RESULTS A total of 54 publications with 32,862 patients from 14 countries qualified for inclusion in the study. The average age was 15.3 years. Children aged 10 years and below represented over 80% of the burn patient population. Males constituted 55% of those who suffered burns. Scalds were the commonest cause of thermal injuries, accounting for 59% of all burns, while flame burns accounted for 33%. The burn mortality averaged 17%, or the death of one of every five burn victims. CONCLUSIONS These statistics indicate the need for an urgent review of burn policies and related legislation across the sub-Saharan region to help reduce burns, and provide a safe environment for children.
