ABSTRACT
Oesophageal involvement due to tuberculosis (TB) and coinfection with HTLV-1 is rare and can be complicated by the presence of other infections that affect the mucosa of the upper respiratory tract, such as COVID-19. We present the case of a 27-year-old male patient, with 3 months of illness, weight loss, dysphagia, and ulcers in the oral cavity. Tomography showed oesophageal perforation and after oesophageal ulcer biopsy, TB was diagnosed, in addition to infection by HTLV-1 and severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). The patient responded satisfactorily to antituberculous treatment and corticosteroids. Considering the association between rare extrapulmonary tuberculosis and other immunosuppressive pathologies, it is crucial to identify these pathologies in such patients.

ABSTRACT
A 64-year-old never-smoker man, with professional exposure, presented to Marius Nasta Pneumophtisiology Institute for fatigability to effort, in the context of severe SARS-COV2 infection one month previously. His medical history includes pulmonary tuberculosis (55 years ago) and newly diagnosed type II diabetes (261 mg/dL glycemia). The thoracic tomography computer in the immediate post-COVID period (Fig. 1A) revealed the presence of glass ground lesions and a 3 cm nodule with cystic degeneration in the upper left lobe. A gross examination of the specimen identified a condensation area of 2.5 cm diameter, brown-grey colored, with necrosis and central ulceration. Microscopic examination showed the presence of bronchiectasis with squamous metaplasia of the epithelium, which appears ulcerated;numerous calcium oxalate crystals with adjacent foreign body granulomatous reaction;endobronchial are present fibrinous and inflammatory debris, brown-black pigment, and septate, dichotomous branching hyphae, suggestive of Aspergillus spp. A periodic acid-Schiff stain was performed, identifying the fungal hyphae. The histopathological diagnosis was bronchiectasis supra-infected and colonized with fungal filaments (Aspergillus niger).
ABSTRACT
In 2021, 6.5 million cases of tuberculosis (TB) were reported globally;however, the WHO estimates that 10.6 million people (134/ 100,000) developed the condition. As many as 1.6 million people (20/100,000) died of TB. The increase in TB mortality to the 2017 level may be explained by worse access to the diagnosis and treatment of TB due to the COVID-19 pandemic. In Europe, TB primarily affects vulnerable populations such as migrants, homeless people, prisoners or HIV-positive persons. The WHO estimates the incidence of TB in Ukraine to be 71/ 100,000. Approximately a third of cases are multidrug-resistant and one in five patients is HIV-positive. The Czech Republic is among countries With the lowest TB rates globally. In 2021, 357 cases (34/100,000) were reported to the national TB registry. Data for 2022 are not available as yet but the total number of TB cases is expected to rise in the Czech Republic, resulting from more reported cases of TB in Ukrainians due to the war in Ukraine. Fortunately, TB rates in Ukrainian refugees are considerably lower than those estimated When the war started.
ABSTRACT
Background and Aim: Leishmaniasis is a parasitic disease transmitted by sandflies and is one of the endemic diseases of Iran. With the spread of the Covid-19 epidemic worldwide, the virus will interface with endemic infectious diseases in different regions. In this study, coronavirus disease was evaluated in patients with a history of leishmaniasis referred to the Center of Research and Training in Skin Diseases and Leprosy. Methods: A total of 91 patients with a history of leishmaniasis were studied for possible SARS-CoV-2 infection. The number of patients referred to the Center of Research and Training in Skin Diseases and Leprosy during the coronavirus epidemic was also compared with the same period before the epidemic Results: A total of 60% of patients with leishmaniasis did not report coronavirus disease. Twenty-one percent of cases had a mild corona disease, 13% had a moderate and 3% had severe corona disease. Only a single death was reported in corona patients with a history of cutaneous leishmaniasis. The number of referrals before the beginning of the corona epidemic was twice as high as during the epidemic. Conclusion: In these participants, mortality and side effects of COVID-19 were significantly less reported. However, further studies are needed to evaluate the immune system and cutaneous leishmaniasis protection against COVID-19. Various factors can be effective in reducing patients during the epidemic, including not going to medical centers, reducing the number of trips, and observance of health issues.
ABSTRACT
Background: Tuberculosis or TB is a disease caused by the Mycobacterium tuberculosis complex. There are several comorbidities that experience severity and death when infected with tuberculosis or TB, namely hypertension, diabetes mellitus, cardiovascular disease, chronic kidney disease, cerebrovascular disease, and other diseases. This study aims to estimate the magnitude of the risk of death in Tuberculosis patients undergoing treatment with comorbid Diabetes Mellitus, with a meta-analysis of primary studies conducted by previous authors. Subjects and Method: This was a systematic review and meta-analysis with the following PICO, population: Tuberculosis patients. Intervention: comorbidities of chronic diabetes mellitus. Comparison: without comorbid diabetes mellitus. Outcome: death. The articles used in this study were obtained from three databases, namely Google Scholar, Pubmed, and Science Direct. Keywords to search for articles "Tuberclosis" OR TBC AND "Diabetes Mellitus" OR DM AND Mortality OR Death The included full-text articles are in English with a cohort study design from 2007 to 2021 and report the adjusted Odds Ratio (aOR) in a multivariate analysis. Article selection is done by using PRISMA flow diagram. Articles were analyzed using the Review Manager 5.3 application. Results: A total of 12 cohort studies involving tuberculosis patients undergoing treatment from America, Europe, Africa and Asia were selected for a systematic review and meta-analysis. The data collected showed tuberculosis patients undergoing treatment with comorbid Diabetes Mellitus had a 1.68 times risk of death compared to COVID-19 patients without comorbid chronic kidney disease (aOR = 1.68;95% CI = 1.42 to 1.99;p<0.001). Conclusion: Diabetes mellitus comorbidity increases the risk of death in tuberculosis patients undergoing treatment.
ABSTRACT
In 2017, the French National Health Authority (HAS) reassessed its human immunodeficiency virus (HIV) screening strategy and in 2018, the Joint United Nations Programme on HIV/AIDS (UNAIDS) set the goal of screening 95% of people living with HIV by 2030. The HAS recommends an approach based on target population and gives the general practitioner (GP) a key role in its implementation. It is therefore important to facilitate HIV testing by GPs and to reduce missed opportunities. To this end, a pilot study was conducted on a panel of 2,000 GPs over a 10-month period in 2020 in order to evaluate the impact of a pop-up displayed within prescription assistance software reminding about the frequency of targeted screening recommended by the HAS. The pop-up was displayed for patients with a history of sexually transmitted infection and/or hepatitis C and/or tuberculosis in the previous 12 months and without a known HIV serology or diagnosis. The impact was measured by comparing the prospective follow-up of consultations made during the "pilot" in 2020 with the retrospective follow-up of consultations made during the "pre-pilot" period in 2019. The results showed a significant increase in HIV serology prescriptions during the pilot study, despite the COVID-19 pandemic. Difficulties in objectively identifying target patient profiles and in organizing regular follow-ups to HIV testing were also revealed. This pop-up tool represents an additional means of facilitating the prescription of HIV testing by GPs.
ABSTRACT
Objective: To evaluate the outcome of Coronavirus disease 2019 (COVID-19) infection in children and adolescents with tuberculosis. Methods: We analyzed hospital records for the period May, 2020 to September, 2021 for children who were severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) positive or SARS-CoV-2 antibody positive. They were divided into two groups viz., those with tuberculosis (tuberculosis group) and those without tuberculosis (non-TB group). Demographic information, symptoms, and outcomes of COVID-19 were compared between the two groups. Results: Median (IQR) age of participants was 11 (8,14) and 4.5 (2,9) year for the tuberculosis and non-TB groups, respectively. 93.5% and 36.1% of children were asymptomatic in the tuberculosis and non-TB group, respectively. No variable in the study was significantly associated with COVID-19 positivity in children with tuberculosis. No difference was found in the outcomes of COVID-19 infection in children having tuberculosis. Conclusions: No differences were noted in the outcomes of COVID-19 infection in children having tuberculosis.
ABSTRACT
Introduction: The detection rate of tuberculosis may have changed during the COVID-19 pandemic due to the new reality and habits created to combat the pandemic. Background: To analyze the incidence of tuberculosis in Brazil during the years 2018 to 2020;comparing the detection rate during this period in general and vulnerable populations. Methods: Data on the incidence of tuberculosis in the years 2018, 2019, and 2020 were collected from the Registry of the Brazilian Ministry of Health, taking into account the distribution by age, sex, and affiliation to vulnerable groups such as homeless people, inmates, health professionals and immigrants. Results: The overall number of new tuberculosis cases in 2020 was lower than in 2018 and 2019. There was no difference in the percentage of men and women or between age groups. The incidence of tuberculosis among people belonging to vulnerable groups remained the same in 2020 as in 2018 and 2019. Conclusion: New cases of tuberculosis decreased equally in all segments of the population studied during the COVID-19 pandemic.
ABSTRACT
The possession of exotic animals as pets is a social practice that has become more visible in Mexico in recent years, so it is interesting to understand its environmental and social implications and those related to human health. The present study aims to identify the main species of exotic animals kept as pets and the zoonotic diseases reported in these species. We analyzed official figures of seizures of exotic fauna in Mexico and reviewed specialized literature on zoonotic diseases documented in Mexico in these species. We identified zoonoses in species of fauna that can be acquired legally and illegally in the country, reported in environments in which animals coexist with other species and are in direct contact with people, which represents an important factor in the spread and propensity of this type of disease. We conclude that the sanitary regulation of wildlife markets, the monitoring and studying microorganisms associated with wildlife are valuable strategies to prevent the emergence of zoonoses.
ABSTRACT
Background and purpose: There are limited studies on co-infection of COVID-19 and tuberculosis (TB). This study aimed to describe the clinical, radiological, laboratory characteristics, treatment and outcome of patients admitted with tuberculosis and COVID 19 co-infection. Materials and methods: In this retrospective study, we investigated all patients with either active TB or old TB and COVID-19 admitted to Qaemshahr Razi Teaching Hospital between 2020 and 2022. Results: A total of 9251 patients with COVID-19 were admitted to our hospital between February 2020 and May 2022. There were eight patients with pulmonary tuberculosis and COVID-19 co-infection, including five (62.5%) male patients. The mean age of these patients was 61.13..22.63 years old. The mean time of symptom onset to hospital admission was 15.13..30.56 days and 50% were diagnosed with active TB and other half had old TB. Four patients were admitted to the ICU, three of whom required ventilation. Finally, four (50%) patients deceased. In this study, among factors that influence patients' outcomes, only underlying diseases were significantly associated with death. Conclusion: Tuberculosis is assumed to cause a higher mortality risk in COVID-19 patients, especially in those with chronic underlying diseases.

ABSTRACT
Tuberculosis is a zoonotic disease that is caused by mycobacterium tuberculosis complex and can infect humans, livestock, and wildlife. It spreads primarily through the respiratory tract and was the leading cause of death due to a single infectious disease before the COVID-19 pandemic. TB is a global public health emergency that has reemerged over the past few decades. Substantial efforts are needed to achieve the goals of the End TB Strategy. The World Health Organization has estimated that approximately 9.9 million people worldwide contracted TB in 2020 and that approximately 140,000 of the 10 million new cases of active TB in 2019 were zoonotic TB. During the COVID-19 pandemic, the number of new TB diagnoses and reports decreased sharply, from 7.1 million in 2019 to 5.8 million in 2020, returning to 2012 levels far below the approximately 10 million TB cases in 2020. Simultaneously, the global decrease in the absolute number of TB deaths until 2019 was followed by an increase in 2020 in four of the six WHO regions and most of the 30 high-TB-burden countries. Therefore, extensive immediate actions worldwide are required to restore the health system, and innovations are needed to accelerate progress toward a tuberculosis-free world.
ABSTRACT
The epidemiological situation of tuberculosis (TB) in most countries with a low TB incidence is characterized by low transmission rates in the general population and occasional outbreaks. At the time of the COVID-19 pandemic, we should expect it to increase in the post-pandemic period. Most cases of active TB are caused by the reactivation of latent tuberculosis. High concentrations of the disease are recorded in certain risk groups (poor people, homeless people, migrants, prisoners, ethnic minorities and people living with HIV infection or other diseases, excessive drinkers, drug addicts and other marginalized groups). At a time of increasing migration, TB will not be permanently eliminated in any country unless it is eradicated worldwide.
ABSTRACT
OBJECTIVE: To explore the expression of tumor necrosis factor-a (TNF-a), interferon-? (IFN-?), soluble interleukin-2 receptor (sIL-2 R) and C-reactive protein (CRP) in chronic obstructive pulmonary disease (COPD) patients complicated with pulmonary tuberculosis (PTB). METHODS: From Mar 2016 to Mar 2019, the acute stage of COPD patients complicated with active stage of PTB who were treated in the department of respiratory and critical care medicine of the People's Hospital of Liangping District, Chongqing were assigned as the group, the acute stage of COPD patients complicated with recovery stage of PTB were assigned as the group B, the stable stage of COPD patients complicated with active stage of PTB were assigned as the group C, and the stable stage of COPD patients complicated with recovery stage of PTB were assigned as the group D. 25 patients with simple stable stage of COPD, 25 patients with simple recovery stage of PTB, 25 patients with simple acute stage of COPD, 25 patients with simple active stage of PTB and 25 people who received physical examination were chosen as the control group. The serum TNF-a, IFN-?, sIL-2 R and CRP were observed and compared among the groups, and the data were statistically analyzed. RESULTS: The levels of TNF-a, IFN-?, sIL-2 R and CRP of the case groups were significantly higher than those of the control group (P < 0.05). The levels of serum TNF-a, IFN-?, sIL-2 R and CRP of the simple stable stage of COPD group, the simple acute stage of COPD group, the simple recovery stage of PTB group, the simple active stage of PTB group, the group D, the group B, the group C and the group A were elevated successively (P < 0.05). The levels of serum TNF-a, IFN-?, sIL-2 R and CRP of the patients with improved illness condition were reduced after treatment. The AUCs of the TNF-a, IFN-?, sIL-2 R and CRP were respectively 0.706, 0.718, 0.768 and 0.807 in prediction of deterioration of disease. CONCLUSION: The PTB patients complicated with COPD show abnormal expression of serum TNF-a, IFN-?, sIL-2 R and CRP. The TNF-a, IFN-?, sIL-2 R and CRP are associated with the severity of disease and have high value in prediction of the deterioration of disease.
ABSTRACT
Background:Analysis of the impact of the Covid-19 pandemic on the resistance level of Mycobacterium tuberculosis (MTb) isolates to Anti Tuberculosis Drugs (ATD) needs to be carried out considering the level of MTB resistance is an important factor in the occurrence of Multidrug-Resistant TB (MDR-TB) in Indonesia. The purpose of the study was to analyze the impact of the Covid-19 pandemic on the level of resistance of MTb isolates of patients with suspected TB in Surakarta. Subjects and Method: This research is a quantitative descriptive study with a retrospective Cohort based on the medical record data of suspected TB patients at Surakarta Central General Hospital in 2020 - 2021. The sampling technique was random sampling with a total of 200 samples each year. Data analysis used the SPSS 21 program.
ABSTRACT
This study aims to assess the continuity of medical care, the impact on disease condition and to highlight the major challenges faced by people affected by leprosy during the pandemic. Telephonic questionnaire-based survey was conducted among previously registered patients of leprosy at referral hospitals in India. Leprosy affected people aged >18 years, either on treatment or who had completed treatment with access to phone and willingness to participate were included. The questions were asked pertaining to demographic details, baseline disease characteristics and various problems faced during lockdown relating to livelihood, finances, treatment, and mental status. A total of 196 patients consented to participate in the study. Mean age of study participants was 37.31 (13.86) years, male participants (n=123, 62.7%) were more than females (n=73, 37.2%). Overall, 101 patients (51.5%) experienced exacerbation, 21 patients (10.7%) reported improvement and 74 patients (37.8%) reported no change in disease status during the pandemic. Most common difficulty faced was the procurement of medicines (115 patients, 58.6%) followed by difficulty in diagnostic testing (61 patients, 31.1%). Course of treatment was interrupted in 16 patients. Most of the patients (n=147, 75%), agreed that teleconsultation services would aid in management of their disease. The majority of patients (88.2%) were able to continue some form of treatment. Two patients (1%) tested positive for COVID-19. Nearly all patients (n=189, 96.4%) were informed regarding the risks and preventive measures related to COVID-19. Fifty percent of the patients reported deterioration in mental health due to the pandemic. The present study highlights the gaps in healthcare delivery and social inequalities along with their impact on the health, livelihood and mental status of people affected by leprosy during the current COVID-19 pandemic.
