BACKGROUND

Hansen’s Disease, a chronic infectious disease, presents with a variety of cutaneous lesions. Being the “great mimicker” that it is, patients may often be misdiagnosed initially, hence the delay in the initiation of the multidrug therapy. Dermoscopy offers an effective, efficient, operator-friendly and non-invasive adjunctive tool in the diagnosis of Hansen’s Disease.

The general objective of the study is to describe the common dermoscopic features according to clinical and histologic findings among all newly diagnosed Hansen’s Disease patients in a tertiary institution within the study period of 6 months.

Purposive sampling was applied to include all newly diagnosed and biopsy-proven Hansen’s Disease patients aged 18 years to 65 years. Participants were clinically examined and dermoscopy was performed on a representative lesion. Other data were collected from chart review, acid fast smear and histopathology reports.

The main dermoscopic feature of Hansen’s Disease is yellowish orange areas observed in all 23 cases studied regardless of the spectrum. This feature can be attributed well to the presence of granuloma formation and inflammation. Another common feature is the presence of white globules and dots which correlates to the presence of the grenz zone, while vascular structures correlate with dilated blood vessels on histopathology.

The major dermoscopic features seen in the study may add to the clinical clues to arrive at a diagnosis of Hansen’s Disease. Although dermoscopy alone is insufficient for the confirmation of Hansen’s Disease, combining it with physical findings would provide additional basis for its clinical diagnosis.

BACKGROUND: Lepra reactions occur in 10-30% of patients with leprosy. The standard of treatment is prednisone. However , prolonged steroid use may cause side effects such as osteoporosis, hypertension, hyperlipidemia, atherosclerosis and infections. Fusidic acid targets cytokine systems responsible for the production of Type 1 lepra reaction (T1R) and erythema nodosum leprosum (ENL). It may be given as a steroid-sparing agent in treating lepra reactions.

OBJECTIVE: To determine the safety and efficacy of fusidic acid as a steroid-sparing agent in the treatment of  Type 1 and Type 2  lepra reactions.

METHODS: A randomized controlled trial was conducted on 67 subjects with lepra reactions, aged 18-60, each assigned to receive either prednisone or prednisone + fusidic acid for 12 weeks. Severity of lepra reactions were graded quantitatively using a modified scale by Walker et al and van Brakel et al, and qualitatively using modified National Leprosy Control Program (NLCP) Guidelines at baseline, weeks 2,4,6,8,10 and 12. Doses of prednisone needed to control lepra reactions were also noted at each follow up and statistical analyses were done . Adverse reactions were noted.

RESULT: Sixty subjects (89.55%) completed the study. The prednisone + fusidic acid group had lower quantitative and qualitative scores compared to the prednisone group. There were significant differences between the two groups for the quantitative severity scores (p=1.44x10-11) and qualitative severity grading (p=9.36x10-14) at week 12. The mean dose of prednisone was 21.5 mg in the prednisone group and 2 mg in the prednisone + fusidic acid group at week 12 (p=1.01x10-12). No adverse reactions were reported.

CONCLUSION: Fusidic acid tablet 250mg/tab two tablets three times a day is an effective and safe steroid-sparing agent for the treatment of lepra reactions.

INTRODUCTION: Linear IgA bullous disease (LABD) is a rare autoimmune blistering disease characterized by subepithelial bullae and linear IgA deposition along the basement membrane zone of the epidermis. Lesions present as pruritic papulovesicles and tense bullae which may coalesce forming annular or polycyclic urticarial plaques with blistering on the edge of the lesions forming the classic “string of pearls” sign. Lesions may affect the face, trunk, and extensor extremities. Incidence rates range from 0.5 to 2.3 cases per million individuals per year. Due to its rare occurrence, there are only a fewdocumented reports on cases of LABD, particularly in the Filipino population. CASE REPORT: A 33 year-old Filipino female consulted because of a 3-week history of severely pruritic vesicles and crusts on the face, trunk, and arms. Patient noted no gastrointestinal symptoms on consultation. Skin punch biopsy revealed subepidermal blisters with collection of neutrophils at the dermal papillae. Direct immunofluorescence showed strong (+2) deposits of linear IgA at the dermo- epidermal junction in perilesional skin thus validating the diagnosis. The patient’s serum was negative for IgA anti-tissue transglutaminase and IgA antiendomysial antibodies. Patient was treated with topical corticosteroids and Dapsone 50 mgs OD with remarkable improvement. CONCLUSION: Linear IgA bullous disease has very few reported cases especially in the Philippine setting. Dapsone is considered the first-line treatment. The disease may persist for a decade or longer, and relapses may occur. Careful history-taking accompanied by the histological, immunofluorescence, and serological findings must be done to ensure proper treatment and good prognosis.

Introduction: Rosai-Dorfman disease is a rare disease that manifests with painless cervical lymphadenopathy, fever, anemia, an elevated erythrocyte sedimentation rate (ESR), and hypergammaglobulinemia. Extranodal lesions occur in 1/3 of patients, and the skin is involved in more than 10% of cases. Purely cutaneous disease is uncommon and only about more than 100 cases have been reported. Cutaneous Rosai-Dorfman Disease (CRDD) appears to be a distinct entity with different age and race predilection from cases with lymph node involvement. Case report: This is a case of a 40-year-old Filipino female who presented with multiple erythematous papules and plaques with pustules on the cheeks. Skin punch biopsy showed a dense dermal infiltrate of polygonal histiocytes with abundant cytoplasm and vesicular nuclei. Emperipolesis was also present. The histiocytes were highlighted by the immunohistochemical stains S-100 and CD68 and was CD1a negative. Complete blood count and ESR were normal. Cervical lymphadenopathy was absent. Findings were consistent with Cutaneous Rosai-Dorfman disease. The patient was started on methotrexate at 15mg/week with folic acid supplementation. Mild soap, benzoyl peroxide 5% gel and tretinoin 0.05% cream once daily were maintained during the treatment course. There was significant decrease in erythema and size of existing lesions after 2 months. The patient was referred to a hematologist for monitoring of possible future systemic involvement. Conclusion Because of its rarity, clinicopathological correlation is always mandatory to establish a diagnosis of CRDD. Immu- nohistochemical stains are required to differentiate this entity form other forms of Langerhans cell histiocytosis. Multidisci- plinary referral is required to rule out concomitant systemic involvement.

Introduction: Acquired immunodeficiency syndrome-Kaposi sarcoma (AIDS-KS) has unique clinical characteristics, often dis- seminated on presentation, a rapidly progressive course, and often fatal outcome. Describing the epidemiology and clinical characteristics of AIDS-KS in the Philippines may lead to early recognition, diagnosis, and management of this condition, which are the keys to preventing significant complications. Case Series: AIDS-KS in 11 Filipino MSM patients with a mean age of 36.55 years (SD 11.54) was described. Violaceous plaques and nodules were present for an average of 5.1 months prior to diagnosis confirmed by biopsy. Histopathologic findings from all pa- tients were consistent with KS. The median CD4+ count of patients was 44 cells/microliter (range, 4 to 181). Six patients presented with opportunistic infections (OI)/AIDS-related conditions (ARC). The most common OIs observed were pulmonary tuberculosis, oropharyngeal candidiasis, and Pneumocystis jiroveci pneumonia. Nine patients improved with highly active antiretroviral therapy (HAART). One patient required modification on his HAART regimen, which was shifted to 2 NRTI and ritonavir-boosted protease inhibitor, and one patient died due to AIDS-related complications. Conclusion This series of 11 cases of AIDS-KS showed similar demographic, clinical and histopathologic characteristics to pre- viously published studies. Findings suggest the need for earlier recognition and diagnosis. While HAART afforded clinical improve- ment in a majority of patients, other treatment options such as chemotherapy should be considered for appropriate patients.

BACKGROUND

Efforts to control Hansen's d isease have progressed through multidrug therapy implementation. However, documented cases of relapse present challenges to its effective management and eradication. Understanding the contributing factors to relapse is crucial for optimizing treatment strategies and achieving better outcomes against Hansen's Disease.

To determine the epidemiological profile and clinical patterns of patients diagnosed with Hansen's Disease Relapse in selected Tertiary Government Hospitals in the Philippines from November 2016 to October 2021.

This was a multi-center, retrospective study involving a five-year chart review method. Charts of all Hansen's Disease Relapse patients were obtained from participating institutions with necessary approvals. Data collection followed approved forms, and patient profiles were analyzed using descriptive statistics. Pre- and post- relapse profiles were compared using T-tests, Wilcoxon tests, and Fisher's Exact Test. Relapse time across subgroups were assessed using Kruskal-Wallis and Mann-Whitney U tests.

A total of 60 relapse cases were included in the study. Majority were single, unemployed males aged 26-35, with low household screening. The Bacillary Index significantly decreased post- relapse. Documented comorbidities included G6PD deficiency before treatment and lepra reactions during MDT. Patients on 12-month MDT regimens had higher relapse time than those on 24-month regimens.

This study underscores the influence of socioeconomic, gender, and age-related factors on relapse. It emphasizes the imperative for enhanced public health measures in accordance with the WHO Global Leprosy Strategy and the importance of considering clinical factors while advocating for continuous improvements in leprosy management protocols.
