Treatment outcomes of tuberculosis cases by HIV status in Haramaya General Hospital, Ethiopia: A retrospective cross-sectional study.

Tuberculosis (TB) and human immunodeficiency virus (HIV) coinfection pose significant challenges to global health, particularly in achieving the target of ending TB. However, the impact of HIV status on TB treatment outcomes remains unclear, especially in eastern Ethiopia. This study aimed to assess the treatment outcomes of TB cases by HIV status and associated factors in Haramaya General Hospital from November 15 to December 30, 2022. A retrospective cross-sectional study was conducted, reviewing the TB registry and treatment cards of patients who received anti-TB treatment between September 2017 and August 2022. Of the 420 samples addressed, 91.0% (95% CI: 88.3%-96.7%) of all TB patients had successful treatment outcomes. The treatment success rates of HIV-positive and HIV-negative TB patients were 80.0% and 91.9%, respectively. Being HIV-negative (AOR: 2.561, 95% CI: 1.002-6.542), being in the age group of 20 to 35 years (AOR: 2.950, 95% CI: 1.171-7.431), and urban residence (AOR: 2.961, 95% CI: 1.466-5.981) were associated with the TB treatment success rate. There was a high treatment success rate among all patients with TB. HIV status was associated with TB treatment outcomes. Strengthening TB-HIV collaborative activities, providing patient-centered care and support, and frequent monitoring and evaluation are recommended to improve the TB success rate.

Assessment of treatment outcome among HIV positive tuberculosis patients in Visakhapatnam

In March 2016, RNTCP revised its technical and operational guidelines. One of the major additions was introduction of Daily Regimen in the treatment of Drug sensitive TB, started initially among TB-HIV co-infected patients in 2017. The present study was taken up to assess the treatment outcomes of Tuberculosis among TB-HIV co-infected patients and certain factors related to the poorer outcome of the treatment.An Observational Longitudinal study conducted at an ART centre, attached to King George Hospital in Visakhapatnam District, Andhra Pradesh, among all TB-HIV co-infected patients newly diagnosed with Drug Susceptible Tuberculosis, aged above 18years, at the selected ART centre, from the month of June 2018 to December 2018. The sample size calculated was 88 with an absolute precision of 10. Ethical clearance from Institutional Ethics Committee, Andhra Medical College; Written informed consent from all the study participants were taken prior to start of study. Confidentiality of the study participants was maintained Qualitative variables were presented as proportions. Analytical statistics include chi-square test and regression analysis. 74% of the patients had a favourable treatment outcome, 15% of the patients died and 11% of the patients were lost to follow up. Occupational status of the study participant, Socio- economic class, tobacco using habit and their CD4 counts had a statistically significant impact on their TB treatment outcome.CD4 count below 200cells/mm, Tobacco use, Diabetes Mellitus- factors responsible for unfavourable treatment outcome of Tuberculosis treatment Case-specific approaches among LFUs may be carried out to bring improvements in the strategies which are already existing or framing new strategies.

The use of urine lipoarabinomannan for establishing pulmonary TB in HIV patient: case report and systematic review

Introduction: Indonesia is still the country that provides the second-largest estimated number of TB cases worldwide. Several patients had TB with HIV-positive. HIV-positive patients with symptoms suggestive of pulmonary tuberculosis often difficult to produce sputum of sufficient quality. Lateral flow lipoarabinomannan examination with urine specimens is expected to be easy, inexpensive, fast, and accurate point-of-care testing. The aim of this research was to assess the sensitivity and specificity of the lateral flow method in detecting lipoarabinomannan (LAM) from urine specimens in HIV-positive patients with suspected pulmonary tuberculosis. Sputum cultures were utilised as a reference standard. Case Description: A 21-year-old male patient came to the clinic complaining of a cough that had not subsided since the previous month. Cough felt throughout the day with a little white phlegm. The patient admitted to having high-risk sexual behavior and had been tested positive for HIV but had not started antiretroviral therapy. The laboratory examination results showed that the leukocyte count was 3600/mm3 and the radiological examination revealed a chest X-ray within normal limits. The patient had been tested for sputum smears with negative results but was still advised to start TB treatment. The patient has not started treatment because he feels that his sputum smear test results are negative. Currently, the patient is not willing to have his sputum checked again. The polyclinic doctor knows the lipoarabinomannan (LAM) examination that uses urine specimens to diagnose TB but does not yet know its effectiveness for this patient. Conclusion: In this case report, the patient was unwilling to do a diagnostic test related to the TB. The systematic review was that the Alere Determine™ TB LAM Ag may not be clinically applicable for diagnosing tuberculosis infection in patients living with HIV at this time. However, Fujifilm SILVAMP TB LAM® could be regarded as a supplementary tool to the established diagnostic protocol for tuberculosis in HIV-positive patients.

Strain structure analysis of Mycobacterium tuberculosis circulating among HIV negative, positive and drug resistant TB patients attending chest clinics in Western Kenya

BackgroundDespite global tuberculosis (TB) interventions, the disease remains one of the major public health concerns. Kenya is ranked 15th among 22 high burden TB countries globally.MethodsA cross-sectional study was conducted in Western Kenya, which comprises 10 counties. A multistage sampling method was used where a single sub-county was randomly selected followed by sampling two high volume health facility from each sub-county. Identification of spoligotype profiles and their family distribution and lineage level were achieved by comparison with SITVIT database.ResultsLineage distribution pattern revealed that the most predominant lineage was CAS 220 (39.8%) followed by Beijing 128 (23.1%). The other lineages identified were T, LAM, H, X, S and MANU which were quantified as 87 (15.7%), 67 (12.1%), 16 (2.8%), 10 (1.8%), 8 (1.4%) and 5 (0.9%) respectively. CAS and Beijing strains were the most predominant lineage in both HIV negative and positive TB patients. The Beijing lineage was also the most predominant in resistant M. tuberculosis strains as compared to wild type. A total of 12 (2.0%) were orphaned M. tuberculosis strains which were spread across all the 10 counties of the study site. In multivariate logistic regression adjusting for potential cofounders three potential risk factors were significant. HIV status (OR = 1.52, CI = 0.29–3.68 and P value of 0.001), Alcohol use (OR = 0.59, CI = 0.43–3.12 and P-value =0.001) and cross border travel (OR = 0.61, CI = 0.49–3.87 and P value = 0.026). Most M. tuberculosis clinical isolates showed genetic clustering with multivariate logistic regression indicating three potential risk factors to clustering. HIV status (OR = 1.52, CI = 0.29–3.68 and P value of 0.001), Alcohol use (OR = 0.59, CI = 0.43–3.12 and P-value =0.001) and cross border travel (OR = 0.61, CI = 0.49–3.87 and P value = 0.026).ConclusionThere exist diverse strains of M. tuberculosis across the 10 counties of Western Kenya. Predominant distribution of clustered genotype points to the fact that most TB cases in this region are as a result of resent transmission other than activation of latent TB.

Resistant Tuberculosis in HIV-Positive Patients: A Growing Public Health Threat

<i>Introduction: </i>Tuberculosis (TB) is a pathology considered one of the main causes of death by single infectious agent, ranking just after HIV / AIDS. Indeed, its emergence and the difficulty of its treatment, especially in the resistant form, in patients with co-infection with other diseases immundéprimante as HIV.<i> Observation 1:</i> 31 years old presented with febrile headaches complicated by epileptic seizures. The MRI scan showed 3 cockeyed and multilocular lesions suggesting neuromeningeal tuberculosis. HIV serology came back positive and during the first line treatment he relapsed and the resistance test was positive.<i> Observation 2:</i> 45 progressive alteration of the state associated with signs of tuberculosis impregnation and a meningeal syndrome. BK in the CSF and in the sputum was positive and brain imaging allowed us to retain the diagnosis of a neuromeningeal tuberculosis. The patient was put on anti-bacillary ERIP k4 and a corticotherapy. The workup for co-infection was able to establish an HIV infection. After 3 weeks of anti-bacillary treatment, the patient had a bad evolution and the search for resistance came back positive. <i>Observation 3: </i>25 years old, pulmonary tuberculosis manifested by a hemoptysis of small abundance associated with a deep alteration of the general state, 3 BK positive sputum, as well as the image of a tuberculous cavern on the thoracic CT. Bad evolution after 2 months of treatment of first worsening of symptoms neuro and systemic involvement the search for resistance came back positive. <i>Discussion:</i> Drug-resistant tuberculosis is a major global public health challenge. In this article, we present three cases of drug-resistant TB in HIV-coinfected patients, highlighting the emergence and increasing prevalence of multidrug-resistant TB (MDR-TB) strains worldwide. In order to control the spread of this dreaded disease, it is essential to improve treatment regimens, promote vaccination, educate affected patients, and promote adherence to treatment. <i>conclusion: </i>Diagnosis of drug-resistant tuberculosis should be prompt and considered if there is a delay or lack of improvement with conventional tuberculosis treatment.

Uncommon manifestation of disseminated tuberculosis with metastatic skin abscesses in an immunocompromised adult patient: A case report

Background: Cutaneous lesions account for less than 2% of all extrapulmonary manifestations of tuberculosis (TB). Metastatic tuberculous abscesses (tuberculous gummas), uncommon forms of cutaneous TB, typically result from the bacillus spreading hematogenously from the main site of infection to the subcutaneous tissue when the body's cell mediated immunity is compromised and present with one or more non-tender and fluctuant subcutaneous nodules. Case Presentation: A 51-year-old male presented with dry cough of one month duration associated with loss of appetite, easy fatigability and vomiting of ingested matter. He had left armpit and lower back skin swellings of similar duration. Physical findings were remarkable for whitish coat over the dorsal part of the tongue, crepitation over the lower two-third of bilateral posterior chest, and non-tender fluctuant masses over the left axilla and lower back region. Chest X-ray revealed multiple bilateral air space nodules and abdominopelvic U/S showed numerous hypoechoic splenic lesions. Urine lipoarabinomannan and Xpert MTB/RIF (mycobacterium tuberculosis/rifampicin) assay from the axillary skin abscess were positive for MTB. He was started on anti-tuberculous therapy and showed marked improvement after a month of follow up. Conclusion: It is worth considering the uncommon manifestations of tuberculosis including metastatic skin abscesses in the appropriate clinical context, to avoid misdiagnosis and underreporting in high tuberculosis burden countries. We strongly advise the utilization of Xpert MTB/RIF assay and/or urine lipoarabinomannan for the diagnosis of different forms of tuberculosis including cutaneous TB in HIV positive patients, especially in the absence of sputum for microbiologic tests, like in our patient

Screening performance of C-reactive protein for active pulmonary tuberculosis in HIV-positive patients: A systematic review with a meta-analysis.

BackgroundTuberculosis (TB) is the leading infectious cause of mortality worldwide. In the last years, resistant strains of the etiological agent, Mycobacterium tuberculosis, have emerged, thus demanding more triage tests to identify active pulmonary TB (PTB) patients and to evaluate their disease severity. Therefore, acute-phase reaction serum tests are required for monitoring TB patients, among WHO symptom screening recommendations. C-reactive protein (CRP) is a non-specific inflammatory biomarker that has been recently proposed for TB screening and can be quantitatively analyzed through cost-effective point-of-care assays. A previous meta-analysis found CRP to be highly sensitive and moderately specific for active PTB with confirmed HIV infection.MethodsWe performed a meta-analysis update of diagnostic tests, pooling sensitivities, and specificities in order to assess the accuracy of CRP as a potential test for the screening of HIV-associated PTB in outpatients. We searched MEDLINE, Web of Science, and SCOPUS for eligible articles before 19 October 2021.ResultsWe identified 13 eligible studies with HIV-positive patients with PTB. At a CRP threshold of 10 mg/L, CRP pooled sensitivity was 87% (76%–93%) and pooled specificity was 67% (49%–81%), with an area under the curve (AUC) of 0.858. Using a CRP threshold of 8 mg/L, pooled sensitivity was 82% (72%–89%) and pooled specificity was 82% (67%–92%), with an AUC of 0.879. We found that CRP has a high sensitivity in the screening of PTB in HIV-positive outpatients, consistent with findings reported previously.ConclusionsRegardless of pooled specificity, better results were found using the CRP threshold of 8 mg/L as a test screening of PTB, meeting the need of further approaching specific TB diagnostic methods and reducing resource consumption.

Determinants of unsuccessful tuberculosis treatment outcome in Northern Red Sea region, Eritrea.

BackgroundEritrea has achieved the global target (90%) for tuberculosis (TB) treatment success rate. Though, events of unsuccessful TB treatment outcomes (death, treatment failure, lost to follow up and not evaluated) could lead to further TB transmission and the development of resistant strains. Hence, factors related to these events should be explored and addressed. This study aims to fill the gap in evidence by identifying the determinants of unsuccessful TB treatment outcomes in Eritrea’s Northern Red Sea region.MethodsA retrospective cohort study was conducted in Eritrea’s Northern Red Sea region. Data collected using a data extraction tool was analyzed using Stata version 13. Frequencies, proportions, median and standard deviations were used to describe the data. Furthermore, univariable and multivariable logistic regression analysis were performed to determine the risk factors for unsuccessful TB treatment outcomes. Crude odds ratio (COR) and adjusted odds ratio (AOR) with their 95% confidence interval (CI) presented and p-value < 0.05 was considered statistically significant.ResultsAmong 1227 TB patients included in this study, 9.6% had unsuccessful TB treatment outcomes. In multivariable logistic regression analysis, TB cases 55–64 years old (AOR: 2.75[CI: 1.21–6.32], p = 0.016) and those ≥ 65 years old (AOR: 4.02[CI: 1.72–9.45], p = 0.001) had 2.7 and 4 times higher likelihood of unsuccessful TB treatment outcome respectively. In addition, HIV positive TB patients (AOR: 5.13[CI: 1.87–14.06], p = 0.002) were 5 times more likely to have unsuccessful TB treatment outcome. TB treatment in Ghindae Regional Referral Hospital (AOR: 5.01[2.61–9.61], p < 0.001), Massawa Hospital (AOR: 4.35[2.28–8.30], p< 0.001) and Nakfa Hospital (AOR: 2.53[1.15–5.53], p = 0.021) was associated with 5, 4 and 2.5 higher odds of unsuccessful TB treatment outcome respectively.ConclusionIn this setting, old age, HIV co-infection and health facility were the independent predictors of unsuccessful TB treatment outcome.

Risk Factors Associated with Treatment Default Among Tuberculosis Patients in Adamawa State, Nigeria

Background. Tuberculosis is an infectious disease caused by bacteria called Mycobacterium tuberculosis. The treatment of drug-resistant tuberculosis is complex, costly, and usually has poor outcomes. Treatment default is well known as a very significant factor associated with drug-resistant tuberculosis.&#x0D; The aim of this study was to investigate the hazard ratios associated with treatment default among tuberculosis patients in Adamawa State, Nigeria.&#x0D; Materials and Methods. The Cox proportional hazards regression was used to determine the hazard ratios associated with tuberculosis patient treatment default in Adamawa State, Nigeria. The Kaplan-Meier method was used to analyze time-to-event data. The study assessed the survival status and treatment outcomes of tuberculosis patients over a six-month period (January 2019 to June 2019). Data analysis was done using R - Programming Software and the statistical significance was considered at p &lt; 0.05.&#x0D; Results. Out of the 197 (124 males and 73 females) tuberculosis patients, 148 (75.1%) individuals were diagnosed with pulmonary tuberculosis and 49 (24.9%) individuals were diagnosed with extrapulmonary tuberculosis. The treatment outcomes were as follows: 33 (16.8%) patients were cured; 36 (18.3%) individuals completed their treatment; 3 (1.5%) patients died during treatment; 105 (53.3%) subjects defaulted; 8 (4.1%) patients were lost to follow-up; the remaining 12 (6.1%) individuals were still on treatment at the end of the study. According to the Cox proportional hazards analysis, HIV-positive status (p &lt; 0.05, 95% CI [0.361 - 0.879]), primary education level (p &lt; 0.01, 95% CI [1.248 - 3.354]), poor quality of life (p &lt; 0.01, 95% CI [1.239 - 3.511]) and age over 60 years old (p &lt; 0.05, 95% CI [0.569 - 2.206]) were significant hazard ratios to experience the event (treatment default) in the study area.&#x0D; Conclusions. This study revealed that HIV-positive tuberculosis patients, older patients, patients with primary education, and those with poor quality of life are significant risk factors to experience treatment default in the study area. Therefore, it is recommended that stakeholders managing the treatment and care of tuberculosis patients should be dedicated and intentional in the provision of psychosocial therapy to patients with poor quality of life.

A multi-parameter diagnostic clinical decision tree for the rapid diagnosis of tuberculosis in HIV-positive patients presenting to an emergency centre

Background: Early diagnosis is essential to reduce the morbidity and mortality of HIV-associated tuberculosis. We developed a multi-parameter clinical decision tree to facilitate rapid diagnosis of tuberculosis using point-of-care diagnostic tests in HIV-positive patients presenting to an emergency centre. Methods: A cross-sectional study was performed in a district hospital emergency centre in a high-HIV-prevalence community in South Africa. Consecutive HIV-positive adults with ≥1 WHO tuberculosis symptoms were enrolled over a 16-month period. Point-of-care ultrasound (PoCUS) and urine lateral flow lipoarabinomannan (LF-LAM) assay were done according to standardized protocols. Participants also received a chest X-ray. Reference standard was the detection of Mycobacterium tuberculosis using Xpert MTB/RIF or culture. Logistic regressions models were used to investigate the independent association between prevalent microbiologically confirmed tuberculosis and clinical and biological variables of interest. A decision tree model to predict tuberculosis was developed using the classification and regression tree algorithm. Results: There were 414 participants enrolled: 171 male, median age 36 years, median CD4 cell count 86 cells/mm 3. Tuberculosis prevalence was 42% (n=172). Significant variables used to build the classification tree included ≥2 WHO symptoms, antiretroviral therapy use, LF-LAM, PoCUS independent features (pericardial effusion, ascites, intra-abdominal lymphadenopathy) and chest X-ray. LF-LAM was positioned after WHO symptoms (75% true positive rate, representing 17% of study population). Chest X-ray should be performed next if LF-LAM is negative. The presence of ≤1 PoCUS independent feature in those with 'possible or unlikely tuberculosis' on chest x-ray represented 47% of non-tuberculosis participants (true negative rate 83%). In a prediction tree which only included true point-of-care tests, a negative LF-LAM and the presence of ≤2 independent PoCUS features had a 71% true negative rate (representing 53% of sample). Conclusions: LF-LAM should be performed in all adults with suspected HIV-associated tuberculosis (regardless of CD4 cell count) presenting to the emergency centre.

Feasibility and acceptability of using the novel urine-based FujiLAM test to detect tuberculosis: A multi-country mixed-methods study

BackgroundThe novel urine-based FujiLAM test identifies tuberculosis in HIV-positive patients but may be challenging to use at point-of-care (POC). ObjectivesWe assessed the feasibility and acceptability of using the FujiLAM test at point of care in outpatient settings. MethodsWe conducted a mixed methods study in four outpatient settings in Kenya, Mozambique, South Africa, and Uganda between November 2020 and September 2021. The test was performed at POC in existing clinic laboratories and consultation spaces. We performed direct observations in the four health facilities, individual questionnaires, proficiency testing evaluations, and individual interviews among healthcare workers performing the FujiLAM test (healthcare workers), and group discussions with programme managers. ResultsOverall, 18/19 (95%) healthcare workers and 14/14 (100%) managers agreed to participate in the study. Most assessed healthcare workers, including lay health workers (10/11; 91%), met the minimum required theoretical knowledge and practical skill in performing the FujiLAM test. Most healthcare workers (17/18; 94%) found the FujiLAM test overall “Easy/Very easy” to perform. Some challenges were mentioned: many timed steps (5/18; 28%); ensuring correct incubation period (5/18; 28%); test result readability (4/18; 22%); and difficulties with cartridge buttons (3/18; 17%). Half of the healthcare workers regularly performing the test (4/7; 57%) found it “Easy” to integrate into routine activities. Most healthcare workers and managers believed that any healthcare worker could perform the test after adequate training. ConclusionsImplementing the FujiLAM test in outpatient POC settings is feasible and acceptable to healthcare workers and managers. This test can be performed in various clinic locations by any healthcare worker. The timed, multi-step test procedure is challenging and may affect the workload in resource-constrained health facilities.

TRANSVERSE MYELITIS DUE TO TUBERCULOSIS: CASE REPORT WITH NARRATIVE REVIEW

Tuberculosis is a global public health problem, which continues to increase morbidity and mortality around the world. The infectious agent is the well-known Koch bacillus, Mycobacterium tuberculosis complex, discovered in 1882 by Robert Koch. Tuberculosis in the central nervous system with spinal cord involvement is a rare event. It is believed that the medullar infection is due to the contiguity of a bone infection at the vertebral level. The initial symptoms of spinal cord infection are due to the motor and sensory compromise of the compromised spinal cord level. Infection in the central nervous system occurs mainly due to the presentation of meningitis and intramedullary tuberculosis in HIV-positive patients, which is considered to represent only 2% of the cases of tuberculosis of the central nervous system. We present a case of spinal cord involvement due to tuberculosis.

Risk Factors for the Development of Tuberculosis Among HIV-Positive Adults Under Highly Active Antiretroviral Therapy at Government Hospitals in Amhara Region, Ethiopia.

BackgroundTuberculosis is one of the leading infectious diseases for people living with HIV. Therefore, the purpose of this study was to investigate factors affecting the development of TB among HIV-positive adults under treatment in government hospitals of Amhara Region, Ethiopia.MethodsA hospital-based retrospective study design was conducted among 700 HIV-positive adults under HAART in 17 government hospitals in the Amhara region, Ethiopia.ResultsAge of the patients (AOR = 1.122, 95% CI:1.013, 2.234), baseline CD4 cell count (AOR = 0.888, 95% CI: 0.714, 0.945), patients living without their partner (AOR = 1.212, 95% CI: 1.051, 1.123), females under treatment (AOR = 0.786, 95% CI; 0.564, 0.845), non-opportunistic diseases (AOR = 0.865, 95% CI: 0.731, 0.938), patients not disclosed their HIV status (AOR = 1.241, 95% CI: 1.087, 2.341), rural patients (AOR = 1.135, 95% CI: 1.032, 1.453, patient with no education (AOR = 1.125, 95% CI: 1.056, 1.546), low adherence patients (AOR = 1.225, 95% CI: 1.191, 2.453), bedridden patients (AOR = 1.223, 95% CI: 1.131, 1.521), ambulatory patients (AOR = 1.156, 95% CI:1.091, 1.267), non-smoker patients (AOR = 0.854, 95% CI: 0.686, 0.935) significantly affected on the variable of interest. Similarly, alcohol intake, drug toxicity and baseline clinical WHO stages significantly affected for the development of tuberculosis in HIV-positive patients under treatment.ConclusionIn this study, baseline CD4 cell count, female patients, non-opportunistic diseases, and non-smoking status were negatively associated with the development of TB, whereas age of patients, living without partners, patients with no education, patients with low adherence, bedridden and ambulatory patients were positively associated to the development of TB in HIV patients. The findings obtained in this study are important for both service providers and patients. More attention should be given to those positively associated variables to response variables. The regional health bureau should open TB/HIV co-infection subsections like ART sections in each hospital.

THE VALUE OF SERUM SEROMUCOID IN THE DIFFERENTIAL DIAGNOSIS OF BACTERIAL PNEUMONIA AND TUBERCULOSIS IN HIV-POSITIVE PATIENTS.

The aim: To optimize the differential diagnosis of bacterial pneumonia and tuberculosis in HIV-positive patients based on the value of serum seromucoid. Materials and methods: The study included 77 HIV-positive patients with lung pathology. The 1st group consisted of 44 HIV-infected patients with BP; the 2nd group - of 33 patients with HIV/TB co-infection. Level of SSM, CD4+ T-lymphocytes, HIV-1 RNA viral load was determined. Сlinical, laboratory, microscopic, radiological, microbiological, and statistical methods were used in the research. Results: In patients with HIV/TB co-infection CD4+ T-lymphocyte level was lower, and viral load was higher than in HIV-infected patients with BP. The level of SSM was statistically significantly elevated in patients of both groups compared with the control (p<0,001), but in patients with HIV/TB co-infection the values were statistically significantly higher (p<0,001). In patients with BP, the content of SSM≤15,95 TU occurred statistically significantly more often than in patients with TB (χ2= 65,5; p <0,001). No statistically significant relationship between SSM content and CD4+ T-lymphocyte levels was found. Conclusions: The content of SSM in patients with HIV/TB co-infection is statistically significantly higher than in the group of HIV-infected patients with BP. Determination of SSM level can be used as a rapid method of differential diagnosis of BP and TB in HIV-positive patients that will allow to optimize the diagnostic algorithm at the early stage of hospitalization and to receive the necessary timely treatment for HIV-infected patients.

Particularities of radiological lesions in smear-positive and HIV-positive tuberculosis patients in the era of triple antiretroviral therapy at Jamot Yaoundé hospital

Introduction: The aim of this work was to compare the radiological lesions during bacilliferous tuberculosis between HIV positive patients under ARV treatment and HIV negative patients. Methodology: This was a, descriptive and comparative study conducted from December 1, 2018 to May 31, 2019 (6 months) at Jamot Yaoundé Hospital. Smearpositive tuberculosis patients meeting our inclusion criteria were enrolled in the study. We split them into two groups, HIV + and HIV -. The comparison of the data was made by the Chi² test, that of the quantitative data with the Student's T test. A p-value less than 0.05 was considered significant. Results: In total, we recruited 145 patients divided into 2 groups of 63 HIV + patients and 82 HIV-patients. The radiological peculiarities found in HIV were as follows: Normal radiography was more frequent, P = 0.004. Interstitial syndrome was less common. Bilateral involvement was predominant. Right localization and upper lobe lesions were less frequent, P &lt;0.05. Micronodular lesions were more frequent, P &lt;0.05. During the alveolar syndrome, the left side was less affected and the upper lobe was the most; p &lt;0.05. Cavitary, pleural, mediastinal and bronchial syndromes did not show statistically significant differences. Conclusion: Although a normal x-ray does not exclude pulmonary tuberculosis, the x-ray lesions are multiple but are dominated by the interstitial syndrome. In patients immunocompromised to HIV, bilateral involvement predominates. The right localization and lesions of the upper lobe are less frequent. Micronodular lesions are frequent.

Possibilities of specific immunological tests in patients with TB/HIV coinfection

The objective of the study: to study the possibilities of skin tests with tuberculosis recombinant allergen (TRA) in the diagnosis of tuberculosis in HIV-positive patients in the region with a high prevalence of tuberculosis.Subjects and Methods. Medical files of 85 patients were retrospectively analyzed, all the patients suffered from TB/HIV coinfection and underwent the skin test with TRA.Results. The skin test with TRA was found to be significantly valuable for the diagnosis of tuberculosis in patients with TB/HIV coinfection. The correlation between the intensity of response to the TRA test and CD4+ count was detected (p = 0.011). The lowest values were observed for CD4+ counts below 100 cells/μL. The direct correlation between the intensity of response to TRA and the stage of HIV infection was proved. No effect of the form of tuberculosis, the phase of the tuberculosis disease, or drug sensitivity on the intensity of response to TRA was found. Among tuberculosis patients with bacterial excretion (n = 48), 68.8% of patients responded positively to the TRA test, and in those with no bacterial excretion, the positive reaction was observed in 81.1%.

Clinical factors associated with unfavorable outcomes in HIV-positive tuberculosis patients

The objective: to identify clinical factors with the highest sensitivity and specificity associated with an unfavorable outcome in the patient with tuberculosis and HIV infection.Subjects. 363 patients with TB/HIV co-infection. Group 1 – 59 (16.3%) patients with the unfavorable outcome, Group 2 – 304 (83.7%) patients with a favorable outcome.Methods: analysis of paired contingency tables by Pearson criterion, quantitative signs by Mann – Whitney test, simple and multiple logistic regression.Results. The following factors promoting unfavorable outcomes in the patient with TB/HIV co-infection with the highest sensitivity and specificity were identified: hemoglobin level (sensitivity – 78.0%; specificity – 73.7%), gastrointestinal candidiasis (72.9% and 84.5%), loose stool (40.7% and 97.4%), no lymphadenopathy (89.8% and 57.2%), and headache (49.2% and 88.5%). The combination of these clinical manifestations provides sensitivity of 78.0% and specificity of 94.4%.A formula is proposed for calculating the probability of an unfavorable outcome in the patient TB/HIV co-infection.

Mortality during tuberculosis treatment in South Africa using an 8-year analysis of the national tuberculosis treatment register

In 2011, the South African HIV treatment eligibility criteria were expanded to allow all tuberculosis (TB) patients lifelong ART. The impact of this change on TB mortality in South Africa is not known. We evaluated mortality in all adults (≥ 15 years old) treated for drug-susceptible TB in South Africa between 2009 and 2016. Using a Cox regression model, we quantified risk factors for mortality during TB treatment and present standardised mortality ratios (SMR) stratified by year, age, sex, and HIV status. During the study period, 8.6% (219,618/2,551,058) of adults on TB treatment died. Older age, male sex, previous TB treatment and HIV infection (with or without the use of ART) were associated with increased hazard of mortality. There was a 19% reduction in hazard of mortality amongst all TB patients between 2009 and 2016 (adjusted hazard ratio: 0.81 95%CI 0.80–0.83). The highest SMR was in 15–24-year-old women, more than double that of men (42.3 in 2016). Between 2009 and 2016, the SMR for HIV-positive TB patients increased, from 9.0 to 19.6 in women, and 7.0 to 10.6 in men. In South Africa, case fatality during TB treatment is decreasing and further interventions to address specific risk factors for TB mortality are required. Young women (15–24-year-olds) with TB experience a disproportionate burden of mortality and interventions targeting this age-group are needed.
