OBJECTIVES

 

METHODS

We included all SLE cases reported between January 2021 and December 2022 based on our Rheumatology Section census in this retrospective chart review. We evaluated the changes in the prednisone dosage and the lupus disease activity before, during and after completion of tuberculosis (TB) treatment. The characteristics of the patients were also described.

RESULTS

All the subjects in the study were females with a mean age of 35.85 years. The pulmonary site (50 %) is the most common area of involvement in tuberculosis infection. Prior to anti-TB treatment, the mean MEX-SLEDAI score was 5.45 (SD ± 4.20) within 1 year prior to the TB diagnosis with prednisone dosage mean of 14 mg (SD ± 17.0). Three months after anti-tuberculosis medication initiation, the prednisone dosages and the MEX-SLEDAI increased however, the changes were not statistically significant. Within 1 month of completion of anti-TB treatment, there was decrease in the MEX-SLEDAI with mean of 3 (SD ± 3.68) and dosages of prednisone with mean of 4.38 mg (SD 3.13). The changes were statistically significant with p-values of

CONCLUSION

There were no significant changes in the MEX-SLEDAI and prednisone dosage within 3 months of starting antiTB medications. However, completion of treatment results to better SLE disease scores and lower prednisone requirements.

BACKGROUND AND OBJECTIVE

The COVID-19 pandemic has adversely affected various healthcare services worldwide, including tuberculosis (TB) control programs. This paper examines the impact of the COVID-19 pandemic on TB case notification rate (CNR) and treatment success rate (TSR), and the challenges and interventions in TB-DOTS (directly observed treatment short-course) services in the Province of South Cotabato, SOCCSKSARGEN Region, Philippines. 

METHODS

An explanatory sequential mixed methods design was used to describe the experiences of South Cotabato in implementing TB-DOTS services during COVID-19 pandemic. Monthly data on CNR and TSR under TB-DOTS from March 2019 to February 2022 were retrieved from the Department of Health’s Integrated Tuberculosis Information System (ITIS) through records review. One-way analysis of variance (ANOVA) and Tukey’s test were used to analyze quantitative data. Focus group discussions (FGD) were conducted among four groups of program implementers (NTP coordinators, nurses, medical technologists, and barangay health workers) encompassing the challenges encountered in the implementation of TB-DOTS services as well as interventions done before and during the COVID-19 pandemic.

RESULTS

During the pre-COVID-19 period (March 2019-February 2020), a CNR of 334 per 100,000 population was reported in the province. There is a 35.19% decrease in TB CNR during COVID-19 Year 1 (March 2020-February 2021) at 216 per 100,000 population, followed by a 37.63% increase in Year 2 at 298 per 100,000 population. The mean TSR covering the pre-COVID period was 96% (SD = 0.01) while the mean TSR in COVID-19 Year 1 was 93% (SD = 0.02), significantly lower than that of the pre-pandemic period, followed by monthly TSR ranging from 91% to 98% (SD = 0.02), an increase in Year 2. From the FGDs, six pre-existing barriers were identified such as patients’ f inancial constraints, hard-to-reach areas, poor health seeking behavior, persistence of TB stigma, medicine and supply shortages, and inadequate health workforce were experienced before and during the COVID-19 pandemic. On the other hand, six emerging challenges brought by the COVID-19 pandemic were reallocation of services, movement restriction, additional protocols, reporting delays, and fears among patients and health workers. The decrease in CNR and TSR during COVID-19 Year 1 aligned with the emergence of new challenges in TB-DOTS services brought by the pandemic. These aggravated pre-existing barriers which further caused delays in the diagnosis and treatment of TB patients. Nine interventions done to address these challenges were also described, the most critical being health education, strengthening community-based services, use of telecommunications, resource pooling for essential medicines, adjusting medication dispensing, and coordination with local government units and policy enhancements.

CONCLUSION

TB-DOTS services in South Cotabato experienced various difficulties during the COVID-19 pandemic which led to initial declines in CNR and TSR. Addressing barriers and challenges were vital in ensuring the continuity of TB services and mitigating the impact of COVID-19 crisis on CNR and TSR. This study demonstrates the adaptability and resilience of South Cotabato's TB-DOTS services in response to COVID-19 challenges and highlights the need for strategies ensuring continuity of TB services and healthcare system resilience in light of Universal Health Care. Recommendations are outlined to improve current policies and practices as well as lay future directions for research on health service delivery and program implementation in relation to pandemics and other types of disasters.

Tuberculosis is a global disease with a high prevalence rate in the Philippines. Frank hemoptysis often occurs later in the disease and is usually not massive since the availability of anti-Koch’s treatment. However, Rasmussen’s aneurysm, a pulmonary vascular complication secondary to tuberculosis from the weakening of the pulmonary arterial wall adjacent or within a tuberculous cavity, can be an uncommon cause of massive and potentially fatal hemoptysis.

A 35-year-old male patient presented with episodes of hemoptysis while being treated for pulmonary tuberculosis for two weeks. An episode of massive hemoptysis of ~400ml prompted his admission. Chest tomography with contrast showed bronchiectatic changes, cavitary formation, and an aneurysmal dilatation of the anterior segmental artery of the left upper lobe. He was diagnosed with Rasmussen’s aneurysm. A multidisciplinary team consisting of pulmonologists, interventional radiologists and thoracic surgeons planned for a surgical intervention as coil embolization was deemed to be difficult due to the wide neck character of the aneurysm. On re-admission after patient optimization, repeat chest tomography showed interval regression of pulmonary cavity with thrombosis of the previously identified Rasmussen’s aneurysm. Patient completed his 6-month antitubercular treatment with no further episodes of hemoptysis.

In patients with tuberculosis, hemoptysis results from involvement of the parenchyma, bronchiectasis, or erosion of residual cavities. Hemoptysis from the rupture of a dilated vessel such as Rasmussen’s aneurysm is a rare cause. Chest tomography with contrast is the imaging modality of choice as it demonstrates the focal pulmonary artery dilatation. Embolization or surgical lobectomy are typically utilized to control the bleeding. However, treatment with anti-tuberculous regimen may result already in regression and eventual thrombosis of the aneurysm. Watchful monitoring is imperative as massive hemoptysis may recur; radiologists and surgeons must be available at any time in case intervention is required.

BACKGROUND AND OBJECTIVE

Tuberculosis (TB) remains to be prevalent in the Philippines and globally. Female genital tuberculosis has devastating and permanent consequences, hence, timely and adequate treatment is needed. Since more data regarding optimal duration of treatment of genital tuberculosis are needed, this study compares the treatment response at six months and after at least nine months of treatment, with the intention of determining the most practical management for genital tuberculosis.

METHODS

A retrospective chart review was conducted for newly diagnosed cases of genital tuberculosis who met the inclusion criteria. Treatment response was categorized into clinical, microbiologic, histologic, radiologic, and sonographic responses. Responses to treatment were evaluated as either partial or complete at the 6th month and after at least 9 months of treatment, and the proportions were compared.

RESULTS

Out of 140 charts retrieved, only 43 were included. Statistically significant difference was found only in clinical response, primarily due to patients who did not achieve resumption of menstruation within the f irst six months of treatment. The rest of the treatment responses and adverse drug events are equally the same for both time periods.

CONCLUSION

Results of this study show that the proportion of patients with microbiologic, histologic, radiologic, and sonographic response to treatment at the 6th month did not significantly differ to the proportion of patients who responded at the 9th or 12th month of treatment. This leads to a conclusion that the 6-month treatment regimen will be more practical in treating genital tuberculosis, except in amenorrheic premenopausal women who may warrant extension of treatment. Further studies on post-treatment rates of relapse and sonographic resolution are needed.

BACKGROUND AND OBJECTIVES

Hepatobiliarypancreatic tuberculosis (HBPTB) is a less common form of tuberculosis that often presents as malignancy or lithiasis. Advances in diagnostics and minimally invasive procedures have led to the detection of more patients with milder forms of TB requiring surgical management. Due to the low incidence rates and lack of standardized approaches, additional studies are needed to improve patient outcomes. This study examined the risk factors, diagnostic methods, and treatments for HBPTB patients at the University of the Philippines – Philippine General Hospital (UP-PGH) from January 1, 2014 to December 31, 2021.

METHODS

This retrospective descriptive study utilized our institutional database to identify patients who underwent a surgical procedure for HBPTB and their associated risk factors. Inclusion criteria required biopsy or microbiologic proof of tuberculous involvement of the biliary tract or nearby structures.

RESULTS

Among a total of 45 patients, the most common admitting diagnosis were HBP tuberculosis (37.8%) and malignancy (35.6%). 47.6% of patients had a previous or concurrent TB exposure. Sixty percent had subclinical malnutrition indicated by normal weight and low albumin. The liver (37.8%) and the bile ducts (33.3%) were the most common organs involved. The most common surgical procedures done were ultrasound-guided liver biopsy, biliary enteric anastomosis, percutaneous transhepatic biliary drainage (PTBD), and endoscopic retrograde cholangiopancreatography with or without stenting (ERCP).

CONCLUSIONS

This study provides additional data for clinicians to tailor diagnostic and treatment plans accordingly. Striking a balance between surgical procedures and appropriate anti-tuberculous therapy (ATT) is essential for successful treatment. Local data can be useful to help identify tuberculosis patterns unique to Filipinos and highlight socio-economic factors contributing to this rare presentation of TB.

BACKGROUND AND OBJECTIVES

The Philippines faces challenges in the screening of tuberculosis (TB), one of them being the shortage in the health workforce who are skilled and allowed to screen TB. Deep learning neural networks (DLNNs) have shown potential in the TB screening process utilizing chest radiographs (CXRs). However, local studies on AIbased TB screening are limited. This study evaluated qXR3.0 technology's diagnostic performance for TB screening in Filipino adults aged 15 and older. Specifically, we evaluated the specificity and sensitivity of qXR3.0 compared to radiologists' impressions and determined whether it meets the World Health Organization (WHO) standards.

METHODS

A prospective cohort design was used to perform a study on comparing screening and diagnostic accuracies of qXR3.0 and two radiologist gradings in accordance with the Standards for Reporting Diagnostic Accuracy (STARD). Subjects from two clinics in Metro Manila which had qXR 3.0 seeking consultation at the time of study were invited to participate to have CXRs and sputum collected. Radiologists' and qXR3.0 readings and impressions were compared with respect to the reference standard Xpert MTB/RiF assay. Diagnostic accuracy measures were calculated.

RESULTS

With 82 participants, qXR3.0 demonstrated 100% sensitivity and 72.7% specificity with respect to the reference standard. There was a strong agreement between qXR3.0 and radiologists' readings as exhibited by the 0.7895 (between qXR 3.0 and CXRs read by at least one radiologist), 0.9362 (qXR 3.0 and CXRs read by both radiologists), and 0.9403 (qXR 3.0 and CXRs read as not suggestive of TB by at least one radiologist) concordance indices.

CONCLUSIONS

qXR3.0 demonstrated high sensitivity to identify presence of TB among patients, and meets the WHO standard of at least 70% specificity for detecting true TB infection. This shows an immense potential for the tool to supplement the shortage of radiologists for TB screening in the country. Future research directions may consider larger sample sizes to confirm these findings and explore the economic value of mainstream adoption of qXR 3.0 for TB screening.

OBJECTIVES: This study aimed to investigate the impact of foam macrophages (FMs) on the intracellular survival of Mycobacterium tuberculosis (MTB) and identify the molecular mechanisms influencing MTB survival. METHODS: An in vitro FM model was established using oleic acid induction. Transcriptomic and metabolomic analyses were conducted to identify the key molecular pathways involved in FM-mediated MTB survival. RESULTS: Induced FMs effectively restricted MTB survival. Transcriptomic and metabolomic profiling revealed distinct changes in gene and metabolite expression in FMs during MTB infection compared with normal macrophages. Integrated analyses identified significant alterations in the cyclic adenosine monophosphate (cAMP) signaling pathway, indicating that its activation contributes to the FM-mediated restriction of MTB survival. CONCLUSIONS FMs inhibit MTB survival. The cAMP signaling pathway is a key contributor. These findings enhance the understanding of the role of FMs in tuberculosis progression, suggest potential targets for host-directed therapies, and offer new directions for developing diagnostic and therapeutic strategies against tuberculosis.

OBJECTIVE: To assess the independent and combined effects of air pollutants, meteorological factors, and greenspace exposure on new tuberculosis (TB) cases. METHODS: TB case data from Shanghai (2013-2018) were obtained from the Shanghai Center for Disease Control and Prevention. Environmental data on air pollutants, meteorological variables, and greenspace exposure were obtained from the National Tibetan Plateau Data Center. We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases. RESULTS: Increased TB risk was linked to PM _2.5, PM ₁₀, and rainfall, whereas NO ₂, SO ₂, and air pressure were associated with a reduced risk. Specifically, the strongest cumulative effects occurred at various lags: PM _2.5 ( RR = 1.166, 95% CI: 1.026-1.325) at 0-19 weeks; PM ₁₀ ( RR = 1.167, 95% CI: 1.028-1.324) at 0-18 weeks; NO ₂ ( RR = 0.968, 95% CI: 0.938-0.999) at 0-1 weeks; SO ₂ ( RR = 0.945, 95% CI: 0.894-0.999) at 0-2 weeks; air pressure ( RR = 0.604, 95% CI: 0.447-0.816) at 0-8 weeks; and rainfall ( RR = 1.404, 95% CI: 1.076-1.833) at 0-22 weeks. Green space exposure did not significantly impact TB cases. Additionally, low temperatures amplified the effect of PM _2.5 on TB. CONCLUSION Exposure to PM _2.5, PM ₁₀, and rainfall increased the risk of TB, highlighting the need to address air pollutants for the prevention of TB in Shanghai.

OBJECTIVE: Cigarette smoking exacerbates the progression of pulmonary tuberculosis (TB). The role of tertiary lymphoid structures (TLS) in chronic lung diseases has gained attention; however, it remains unclear whether smoking-exacerbated lung damage in TB is associated with TLS. This study aimed to analyze the characteristics of pulmonary TLS in smokers with TB and to explore the possible role of TLS in smoking-related lung injury in TB. METHODS: Lung tissues from 36 male patients (18 smokers and 18 non-smokers) who underwent surgical resection for pulmonary TB were included in this study. Pathological and immunohistological analyses were conducted to evaluate the quantity of TLS, and chest computed tomography (CT) was used to assess the severity of lung lesions. The correlation between the TLS quantity and TB lesion severity scores was analyzed. The immune cells and chemokines involved in TLS formation were also evaluated and compared between smokers and non-smokers. RESULTS: Smoker patients with TB had significantly higher TLS than non-smokers ( P < 0.001). The TLS quantity in both the lung parenchyma and peribronchial regions correlated with TB lesion severity on chest CT (parenchyma: r = 0.5767; peribronchial: r = 0.7373; both P < 0.001). Immunohistochemical analysis showed increased B cells, T cells, and C-X-C motif chemokine ligand 13 (CXCL13) expression in smoker patients with TB ( P < 0.001). CONCLUSION Smoker TB patients exhibited increased pulmonary TLS, which was associated with exacerbated lung lesions on chest CT, suggesting that cigarette smoking may exacerbate lung damage by promoting TLS formation.

OBJECTIVE: To investigate the spatiotemporal patterns and socioeconomic factors influencing the incidence of tuberculosis (TB) in the Guangdong Province between 2010 and 2019. METHOD: Spatial and temporal variations in TB incidence were mapped using heat maps and hierarchical clustering. Socioenvironmental influencing factors were evaluated using a Bayesian spatiotemporal conditional autoregressive (ST-CAR) model. RESULTS: Annual incidence of TB in Guangdong decreased from 91.85/100,000 in 2010 to 53.06/100,000 in 2019. Spatial hotspots were found in northeastern Guangdong, particularly in Heyuan, Shanwei, and Shantou, while Shenzhen, Dongguan, and Foshan had the lowest rates in the Pearl River Delta. The ST-CAR model showed that the TB risk was lower with higher per capita Gross Domestic Product (GDP) [Relative Risk ( RR), 0.91; 95% Confidence Interval ( CI): 0.86-0.98], more the ratio of licensed physicians and physician ( RR, 0.94; 95% CI: 0.90-0.98), and higher per capita public expenditure ( RR, 0.94; 95% CI: 0.90-0.97), with a marginal effect of population density ( RR, 0.86; 95% CI: 0.86-1.00). CONCLUSION The incidence of TB in Guangdong varies spatially and temporally. Areas with poor economic conditions and insufficient healthcare resources are at an increased risk of TB infection. Strategies focusing on equitable health resource distribution and economic development are the key to TB control.
