Efficacy and Safety of Makabuhay (Tinospora rumphii) 25% Cream Versus Hydrocortisone 1% Cream in the Management of Mosquito Bite Reactions: Randomized Double-Blind Controlled Trial.

BACKGROUND: Most insect bite reactions resolve spontaneously, but the inflammation and pruritus induced have been shown to decrease the quality of life. Previous studies have shown the potential anti-inflammatory properties of Tinospora rumphii. OBJECTIVE: The aim of the study is to assess the efficacy and safety of T rumphii 25% cream versus hydrocortisone 1% cream in the management of local cutaneous reactions caused by mosquito bites. METHODS: This study was a parallel-group, double-blind, randomized, placebo-controlled trial with a 1-week duration in a span of 3 months (June 2019 to August 2019). Participants were exposed to sterile noninfectious mosquitoes (Aedes aegypti) for 5-10 minutes to elicit cutaneous lesions. Tinospora 25% cream or hydrocortisone 1% cream was applied twice daily throughout the 7-day study period. Of the 70 participants screened for this study, which was approved by an institutional review board (IRB 2019-07) at the Dermatology Outpatient Department of the Research Institute for Tropical Medicine, Alabang, Muntinlupa, Philippines, 58 participants in total met the inclusion criteria and were randomized to treatment (Tinospora: n=29) and active control (hydrocortisone: n=29) groups. RESULTS: In total, 58 participants were randomized to receive Tinospora cream (n=29) or hydrocortisone cream (n=29). All participants completed the follow-up. There was a significant decrease in lesion size in both groups from the first 15 minutes to day 7 (P<.001). Comparing the lesion size in both groups, there was a statistically significant decrease in lesion size in the first hour (P=.003) and after 24 hours (P=.03). On day 1, 10% (n=29) of participants in the hydrocortisone group and 7% (n=29) in the Tinospora group experienced complete resolution. On day 3, all participants experienced complete resolution. No adverse effects were documented. CONCLUSIONS: Tinospora 25% cream is safe, effective, and comparable to hydrocortisone 1% cream as an anti-inflammatory agent for mosquito bite reactions based on the decrease in lesion size, the proportion of participants with complete resolution of wheals, and improvement in pruritus intensity score using a visual analog scale. Long-term safety studies are recommended. TRIAL REGISTRATION: Philippine Health Research Registry PHRR230716-005932; https://www.herdin.ph/index.php/registry?view=research&layout=details&cid=5932.

Experience with bilastine in the management of urticaria: Original Real-world cases of Bilastine In Treatment (ORBIT) in Asia.

Urticaria is a disabling condition, resulting in an impaired quality of life and sleep disruption, and can have an adverse impact on work-related or school-related performance and attendance. It is defined according to the presence of unknown (chronic spontaneous urticaria) or known (inducible urticaria) eliciting factors. Guidelines recommend second-generation H1-antihistamines for the first-line treatment of urticaria. Bilastine is indicated in adults, adolescents (aged ≥12 years) and children (aged ≥2 years (Mexico and some African countries), ≥4 years (Canada) or ≥6 years (Europe)) with a body weight of at least 20 kg for the symptomatic treatment of urticaria and allergic rhino-conjunctivitis. The aim of the Original Real-world cases of Bilastine In Treatment (ORBIT) study was to review real-world cases from across the Asia-Pacific region supported by evidence-based literature. Eight diverse, real-world, difficult-to-treat cases with urticaria in people aged 10-75 years are presented. Once-daily bilastine (20 mg (adults/adolescents) or 10 mg (children)) was found to be well tolerated and effective in the long-term management of chronic spontaneous urticaria and inducible urticaria.

Economic Burden of the Inadequate Management of Allergic Rhinitis and Urticaria in Asian Countries Based on the GA²LEN Model.

PURPOSE: Across Hong Kong, Malaysia, the Philippines, Singapore, Thailand and Vietnam, (referred to as Asia) approximately 30-53 million individuals of the 151 million employed suffer from allergic rhinitis (AR) and urticaria. It is estimated that approximately 90% of patients with these allergic conditions are insufficiently treated, impacting the socioeconomic burden in terms of absence from work and decreased productivity. This study aims to estimate the socioeconomic burden of allergies in Asia and the cost savings that their adequate management can provide. Due to the limited availability of regional data, this study focused AR and urticaria in selected countries. METHODS: Published literature, information from statistical bureaus, clinician surveys and extrapolation of selected data from the European Union were used to determine the socioeconomic costs of AR and urticaria. RESULTS: Many patients in Asia suffer from perennial allergies and experience symptoms of AR and urticaria for up to 298 days per year. An estimate of the indirect costs of patients insufficiently treated for AR and urticaria amounts to USD 105.4 billion a year, which equates to USD 1,137-2,195 per patient due to absenteeism and presenteeism. Adherence to guideline-approved treatment can lead to estimated savings of up to USD 104 billion. CONCLUSIONS: The current study suggests that within Asia, the socioeconomic impact of AR and urticaria is similar to that seen in the European Union in spite of the lower wages in Asia. This is due to the mainly perennial allergens prevailing in Asia, whereas the sensitization patterns observed in the European Union are dominated by seasonal exposure to pollen. These results underline the need for governmental initiatives to increase public awareness on the prevention and treatment of these and other allergic diseases as well as greater research funding and large-scale studies to reduce their growing socioeconomic burden in coming years.

Selecting optimal second-generation antihistamines for allergic rhinitis and urticaria in Asia.

BACKGROUND: Allergic diseases are on the rise in many parts of the world, including the Asia-Pacific (APAC) region. Second-generation antihistamines are the first-line treatment option in the management of allergic rhinitis and urticaria. International guidelines describe the management of these conditions; however, clinicians perceive the additional need to tailor treatment according to patient profiles. This study serves as a consensus of experts from several countries in APAC (Hong Kong, Malaysia, the Philippines, Singapore, Thailand, Vietnam), which aims to describe the unmet needs, practical considerations, challenges, and key decision factors when determining optimal second-generation antihistamines for patients with allergic rhinitis and/or urticaria. METHODS: Specialists from allergology, dermatology, and otorhinolaryngology were surveyed on practical considerations and key decision points when treating patients with allergic rhinitis and/or urticaria. RESULTS: Clinicians felt the need for additional tools for diagnosis of these diseases and a single drug with all preferred features of an antihistamine. Challenges in treatment include lack of clinician and patient awareness and compliance, financial constraints, and treatment for special patient populations such as those with concomitant disease. Selection of optimal second-generation antihistamines depends on many factors, particularly drug safety and efficacy, impact on psychomotor abilities, and sedation. Country-specific considerations include drug availability and cost-effectiveness. Survey results reveal bilastine as a preferred choice due to its high efficacy and safety, suitability for special patient populations, and the lack of sedative effects. CONCLUSIONS: Compliance to the international guidelines is present among allergists, dermatologists and otorhinolaryngologists; however, this is lower amongst general practitioners (GPs). To increase awareness, allergy education programs targeted at GPs and patients may be beneficial. Updates to the existing international guidelines are suggested in APAC to reflect appropriate management for different patient profiles and varying symptoms of allergic rhinitis and urticaria.

Leprosy in the Philippines: a review.

Leprosy is a skin disease that accounts for serious deformities and disabilities, leading to stigmatization and psychosocial suffering. It is included in "The Neglected Tropical Diseases". Not surprisingly, its management is increasingly reported as a function of Dermatology Departments, with a strong community-orientated bias. Prompt and accurate diagnosis of leprosy is crucial in the control of leprosy. Its management requires a multidisciplinary team of skilled physicians, laboratory staff, and nurses. All members of the health sectors should remain vigilant to combat this battle against leprosy.
