ABSTRACT
Background: Post kala-azar dermal leishmaniasis (PKDL) is a recognized dermatologic complication of successfully treated visceral leishmaniasis (VL). PKDL lesions are suspected to be important reservoirs for VL transmission in Sudan. Prolonged treatment schedules, feeling of general well-being and the social stigmata of PKDL prevent most patients seeking treatment. The mainstay of treatment is cardiotoxic sodium stibogluconate (SSG) for 60-120 days. Recently, liposomal amphotericin B (Ambisome®) and immunochemotherapy gave promising results. Ambisome® is expensive and difficult to prepare under field conditions. Paromomycin/SSG combination has been shown to be safe, efficacious and can save time in VL treatment. This study aims to prove that Paromomycin/SSG combination can cure and reduce PKDL treatment duration. Methods: We are reporting nine cases of patients with PKDL lesions of ≥6 months duration who were diagnosed by clinical signs, histopathological/immunohistochemical and PCR. Results: Patients’ mean age was 11.7 ± 4.3 years. A third of the patients (3/9; 33.3%) who failed previous SSG treatment of 2-3 months duration responded completely to 40 days of paromomycin/SSG combination. The majority of patients (5/9; 55.6%) responded completely to 30 days of the combination. One patient (1/9; 11.1%) relapsed following 30 days paromomycin/SSG combination. Conclusion: It was concluded that paromomycin/SSG combination for 30 days is time-saving, safe and efficacious for PKDL treatment.
ABSTRACT
Dermatitis herpetiformis (DH) is an autoimmune blistering disorder associated with a gluten-sensitive enteropathy (GSE), and is generally accepted as a cutaneous manifestation of celiac disease and is characterized by grouped excoriations; erythematous, urticarial plaques; and papules with vesicles. We reported an interesting case of adult DH occurred in a 30 year old Sudanese young adult with chronic inflammatory bowel disease, presented with typical string of pearls in the face, trunk and extremities for 2 months duration. The case is diagnosed and confirmed as DH where histopathologically shows a sub-epidermal bulla with microabscess formation, sigmoidoscopy and H. pylori ELISA test were positive IgA. Our case had an adult onset of presentation. Clinical features and histopathology are typical. It is associated of H. Pylori, although poorly responding to triple therapy (Doxycyclin 100 mg bid for 8 days, Cefixime 400 mg for 5 days and Rabeprazole as proton pump inhibitor (PPI) 20 mg for 28 days), but focusing as possible antigen was of paramount concern as possible causative antigen; as in this case all serological specific tests for Coeliac disease were negative. The case was considered to be the second case of DH with CIBD due to H. Pylori been reported in Sudan.
