BACKGROUND

Pneumococcal vaccination has been widely used for the prevention of pneumococcal disease, with two types of vaccines available since 2009. With the World Health Organization (WHO) recommendation of incorporating pneumococcal conjugate vaccines (PCVs) in National Immunization Programs (NIPs) worldwide, a ten-valent PCV (PHiD-CV) was initially introduced in the Philippines in 2012. This, however, transitioned to the use of the 13-valent PCV (Prevnar) subsequent to the recommendation of the Formulary Executive Council in 2014.

OBJECTIVE

This review aimed to present evidence on pneumococcal disease and vaccine inclusion in the Philippine NIP from 2005 - 2021.

METHODS

This narrative review compiled articles on Pneumococcus from January 2005 to October 2021, sourcing literature from databases such as BIOSIS Preview, CAB Direct, Embase, Google Scholar, and others.

RESULTS

In the Philippines, there was a shift in prevalent serotypes of Streptococcus pneumoniae among children under five following the introduction of PCV13 in the National Immunization Program in 2014, with serotype 14 becoming the most common by 2018, and a significant reduction in isolates reported in 2020, where only serotypes 5, 19A, and 23F were identified among invasive strains. The immunogenicity results of a potential vaccine candidate should be factored into the overall evidence when conducting a reassessment of PCV.

CONCLUSION

As part of the decision making about the inclusion of the PCVs in the NIP of the Philippines, various factors such as local epidemiology, vaccine supply, cost, and programmatic characteristics must be careful weighed. Enhancing laboratory and surveillance capacity are essential to provide evidencebased decision-making in terms of existing serotype distribution and antimicrobial resistance (AMR) profile in the country. With the introduction of a new affordable formulation of a 10-valent PCV offering a comparable serotype coverage, the reassessment of choice of PCV with the consideration of all three formulations, namely PCV13, PHiD-CV, and SIIPL-PCV, may be warranted.

BACKGROUND

The World Health Organization (WHO) estimates that in 2015, approximately 325 million or 4.4% of the global population were living with chronic hepatitis B or hepatitis C infection. In the same year, around 1.34 million died from this disease.

OBJECTIVES

This study aimed to estimate the burden of hepatitis B in the Philippines and to determine the costeffectiveness of possible interventions.

METHODS

This study utilized the Center for Disease Analysis Foundation’s (CDAF’s) mathematical disease burden model of hepatitis B. Model inputs were collected using literature review, key informant interviews, expert panel interviews, and records review, and were validated through a series of round table discussions with experts.

RESULTS

Results show that in 2017, the prevalence of chronic hepatitis B infection in the Philippines was 9.7%, equivalent to 10 million infected individuals. Although the model projects a decreasing trend in chronic hepatitis B virus (HBV) infections, liver-related mortality and morbidity due to these viruses are expected to rise if the status quo is maintained. Results show that substantial increase in government subsidy for WHO elimination scenarios would be required to achieve cost-effective outcomes.

CONCLUSION

Hepatitis B remains a huge problem in the Philippines. The HBV modelling exercise reveal that it will be worthwhile and cost-effective to adhere to the WHO elimination targets. A substantial financial investment will be necessary to do so, specifically a significant scale up in the screening, diagnosis, treatment, and monitoring of patients with HBV. While this modelling exercise does not yield burden of disease as accurate as a prevalence survey, experts consulted in the round table discussions agreed with the modelling inputs.

BACKGROUND

The Philippines has been significantly affected by the HIV epidemic in the Asia-Pacific region, with a notable increase in new cases over the past decade. Despite efforts to promote HIV testing, access to treatment, and awareness campaigns, progress has been slow, particularly among youths. Tangere, a market research application, conducted surveys during and after the COVID-19 pandemic to assess HIV knowledge among Filipinos.

OBJECTIVES

This study aimed to evaluate changes in HIV awareness among young Filipinos during and after the COVID-19 pandemic using data collected via Tangere’s surveys. Specifically, it sought to analyze demographic characteristics, sources of HIV information, and knowledge regarding HIV transmission, prevention, and stigma.

METHODS

Tangere collaborated with the investigators to develop a questionnaire assessing HIV knowledge among young Filipinos. Surveys were conducted during and after the COVID-19 pandemic, targeting subscribers aged 18-35 years, primarily from the National Capital Region and Luzon area. Data analysis involved calculating frequencies and percentages to summarize demographic characteristics and HIV knowledge. An Independent-Samples Proportions procedure was used to compare HIV knowledge during and after the pandemic.

RESULTS

The survey revealed that while respondents generally possessed reasonable knowledge about HIV, there were notable changes in the awareness during and after the pandemic. Social media and television were identified as primary sources of HIV information. Knowledge regarding HIV transmission and prevention increased postpandemic, particularly concerning preventive measures such as pre-exposure prophylaxis (PREP) and motherto-child transmission (MTCT). However, persistent misconceptions and stigma surrounding HIV remained, indicating the need for continued education and advocacy efforts.

CONCLUSION

The study underscores the importance of utilizing social media platforms for HIV awareness campaigns, especially among youths who are disproportionately affected by the epidemic. Despite improvements in knowledge, the Philippines has yet to achieve global HIV prevention goals. Continued efforts to enhance awareness, particularly regarding recent advancements in HIV prevention and treatment, are essential for curbing the epidemic and improving public health outcomes nationwide.

OBJECTIVES

To explore the lasting lived experiences of Filipino adults who were isolated due to COVID-19 as late adolescents and examine how these experiences shaped their health consciousness

METHODS

This qualitative study employed an interpretative phenomenological analysis using Colaizzi’s method. Six participants aged 18 and above, who were aged 17–19 during their COVID-19 diagnosis and isolation, were recruited. One-onone semi-structured interviews were conducted and thematically analyzed.

RESULTS

Four main themes emerged: (1) Sources of Stress including academic disruptions, isolation, symptoms and healthcare inefficiencies; (2) Attitudes Toward the Experience ranging from fear to calm acceptance and social responsibility; (3) Coping Strategies such as external support and personal mechanisms like spirituality and hobbies; and (4) Impact of COVID-19 which encompassed interpersonal growth, normalization of illness and varying degrees of health behavior change.

CONCLUSION

While the experience of isolation during adolescence posed significant stress, it also offered opportunities for personal and interpersonal growth. Most participants exhibited increased health consciousness, though behavior change was limited. These insights highlight the value of integrating health behavior interventions for young adults shaped by pandemic experiences.

OBJECTIVES

This study aimed to evaluate the comparative efficacy of Saccharomyces boulardii and Bacillus clausii in the treatment of acute diarrhea

METHODS

A systematic search of MEDLINE, EBSCO, Clinical Key, the Cochrane Library, Academia, and Google Scholar was conducted to identify clinical trials using Saccharomyces boulardii and Bacillus clausii as interventions. The primary outcome measure was the duration of diarrhea. Risk of bias was assessed using the CEBM Critical Appraisal tool and the Cochrane Collaboration tool. Data were analyzed using RevMan 5.4 software.

RESULTS

Four studies involving 411 participants were included in the systematic review and meta-analysis. All studies demonstrated a weighted mean decrease in the duration of diarrhea, ranging from 4.70 to 25.20 hours, favoring Saccharomyces boulardii. The pooled analysis revealed a significant reduction of 24.98 hours in the duration of diarrhea, favoring Saccharomyces boulardii (p < 0.0001).

CONCLUSION

A systematic review and meta-analysis of four clinical trials showed that Saccharomyces boulardii is more effective than Bacilus clausii in reducing the duration of diarrhea among patients with acute diarrhea. These findings support the use of Saccharomyces boulardii as a preferred probiotic intervention for the treatment of acute diarrhea.

Adrenal cortical carcinoma (ACC) is a rare malignancy, and oncocytic ACC (OAC) is a rare histopathologic variant of ACC, with <70 cases documented worldwide as of 2021. This is a case of a 64-year-old female initially presenting with epigastric-to-periumbilical pain, left flank pain, nausea, vomiting, and bloatedness. Computed tomography (CT) urogram revealed a 12.2 x 12.7 x 15 cm left adrenal mass, with pulmonary metastases on chest CT. The patient was clinically and biochemically unremarkable based on the hormonal panel. Left thoracoabdominal adrenalectomy was done, and the left adrenal mass was identified as a high-grade non-functioning OAC on histopathology and immunohistochemistry. The patient showed clinical improvement on chemotherapy with etoposide, cisplatin, doxorubicin (EDP), without mitotane, due to local unavailability. In conclusion, while EDP + mitotane is the standard therapy for metastatic cases, EDP alone showed promising outcomes in improving quality of life and resolving paraneoplastic neuropathy in the absence of mitotane. To date and to the best of our knowledge, this is the first documented case of non-functioning OAC in the Philippines. DS-related Kaposi sarcoma (KS) progresses rapidly with early mucosal and systemic involvement. Early diagnosis and treatment are crucial as they significantly impact the outcome. This is a case of disseminated cutaneous and gastrointestinal KS in a 24-year-old Filipino male living with HIV, presenting with hyperpigmented violaceous subcutaneous nodules, odynophagia, progressive dysphagia, and symptomatic anemia. Capsule endoscopy demonstrated utility in diagnosing gastrointestinal KS lesions, highlighting its crucial role when conventional upper endoscopy was challenging due to oropharyngeal involvement. Diagnostic limitations, mainly the unavailability of human herpesvirus-8 (HHV-8) immunohistochemical stain, were addressed through high clinical suspicion. Multidisciplinary approach including chemotherapy with liposomal doxorubicin, radiotherapy, and supportive care eventually yielded good clinical response. This case emphasizes the importance of early diagnosis, timely intervention, and long-term surveillance in achieving favorable outcomes for patients with KS despite some diagnostic limitations.

Objective: Stroke is the second-leading cause of death globally. Intracranial atherosclerotic stenosis (ICAS) represents 10-15% of ischemic strokes in Western countries and up to 47% in Asian countries. Patients with ICAS have an especially high risk of stroke recurrence. The aim of this meta-analysis is to reassess recurrent stroke, transient ischemic attack (TIA), and other outcomes with stenting versus best medical management for symptomatic ICAS. Methods: The search protocol was developed a priori according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The OVID Medline, Embase, Web of Science, and Cochrane Library databases were searched from inception to August 14th, 2022. Results: This Meta-analysis Included Four Randomized Controlled Trials (Rcts), With A Total Number Of 991 Patients. The Mean Age Of Participants Was 57 Years. The Total Number Of Intracranial Stenting Patients Was 495, And The Number Of Medical Treatment Patients Was 496. The Included Studies Were Published Between 2011 And 2022. Two Studies Were Conducted In The Usa, And The Other Two In China. All Included Studies Compared Intracranial Stenting To Medical Treatment For Icas. Conclusions In patients with ischemic stroke due to symptomatic severe intracranial atherosclerosis, the rate of 30-day ischemic stroke, 30-day intracerebral hemorrhage, one-year stroke in territory or mortality favored the medical treatment alone without intracranial stenting. The risk of same-territory stroke at last follow-up, disabling stroke at last follow-up, and mortality did not significantly favor either group. Intracranial stenting for atherosclerosis did not result in significant benefit over medical treatment.

Background and Objective: Convalescent plasma therapy (CPT) may reduce the risk of disease progression among patients with COVID-19. This study was undertaken to evaluate the efficacy and safety of CPT in preventing ICU admission among hospitalized COVID-19 patients. Methods: In this open-label randomized controlled trial, we randomly assigned hospitalized adult patients with COVID-19 in a 1:1 ratio to receive convalescent plasma as an adjunct to standard of care or standard of care alone. The primary endpoint was ICU admission within first 28 days of enrolment. Primary safety endpoints include rapid deterioration of respiratory or clinical status within four hours of convalescent plasma transfusion and cumulative incidence of serious adverse events during the study period including transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), severe allergic reactions, and transfusion-related infections. Results: A total of 22 patients were assigned to receive convalescent plasma as an adjunct to standard of care and 22 to receive standard of care alone. The median time from onset of COVID-19 symptoms to study enrolment was eight days (IQR, 4 to 10). Two patients (9.1%) in the CPT group and one patient (4.5%) in the control group were admitted to the ICU. The primary outcome measure, ICU admission, was not different between the two groups (q-value >0.9). No patient who received convalescent plasma had rapid deterioration of respiratory/clinical status within four hours of transfusion and none developed TRALI, TACO, anaphylaxis, severe allergic reactions, or transfusion-related infections. There was also no significant difference in the secondary outcomes of 28-day mortality (two patients in the CPT group and none in the control group, q-value >0.90), dialysis-free days, vasopressor-free days, and ICU-free days. Conclusions Among hospitalized COVID-19 patients, no significant differences were observed in the need for ICU admission between patients given CPT as adjunct to standard of care and those who received standard of care alone. Interpretation is limited by early termination of the trial which may have been underpowered to detect a clinically important difference.
