Antimalarie photoprotection

Carlo Mainetti, Benedetta Terziroli Beretta-Piccoli, Carlo Selmi
Dermatomyositis (DM) is an idiopathic inflammatory myopathy characterized by the presence of skin lesions and inflammation of skeletal muscles; however, this feature may be absent in amyopathic DM. DM is a rare disease, occurring at any age, and has two peaks of incidence: one in childhood between 5 and 15 years of age and one in adulthood between 40 and 60 years, with a female preponderance. DM has been associated with malignancy; therefore, every newly diagnosed patient should undergo screening investigations, but evidence-based guidelines on their extension are lacking...

Quinine, a treatment used in chloroquine-resistant falciparum malaria, was loaded into poly(ɛ-caprolactone) or Eudragit® RS100 nanocapsules using Curcuma oil as the oil-based core. Until now, the effect of cationic nanocapsules on malaria has not been reported. A 24 factorial design was adopted using, as independent variables, the concentration of Curcuma oil, presence of quinine, type of polymer, and aqueous surfactant. Diameter, zeta potential, and pH were the responses studied. The formulations were also evaluated for drug content, encapsulation efficiency, photostability, and antimalarial activity against Plasmodium berghei-infected mice...

Lupus tumidus is considered a rare subtype of chronic cutaneous lupus erythematosus, characterized by erythema and bright urticarial erythematous-violaceous lesions that leave no scars after regression. Histopathology reveals perivascular and periannexal lymphohistiocytic infiltrates in the papillary and reticular dermis and interstitial mucin deposition. Treatment is based on photoprotection, topical corticosteroids and antimalarials. We report two cases of lupus tumidus, which deserve attention for their low frequency in the literature, in addition to their relevance as a differential diagnosis among dermatologic disorders...

Pyrroloquinone ring systems are important structural units present in many biologically active molecules including a number of marine alkaloids. For example, they are found in a series of marine metabolites, such as tsitsikammamines, zyzzyanones, wakayin, and terreusinone. Several of these alkaloids have exhibited antimicrobial, antimalarial, antifungal, antitumor, and photoprotecting activities. Synthesis of pyrroloquinone unit is the key step in the synthesis of many of these important organic molecules. Here, we present a ceric (IV) ammonium nitrate (CAN) mediated oxidative free radical cyclization reaction of 1,3-dicarbonyl compounds with aminoquinones as a facile methodology for making various substituted pyrroloquinones...

Vitamin D is a steroid hormone that, in addition to its actions on calcium and bone metabolism, exhibits a plethora of regulatory effects on growth, proliferation, apoptosis and function of the cells of the immune system that are relevant to the pathophysiology of systemic lupus erythematosus (SLE). Hypovitaminosis D is highly prevalent in SLE as a result of avoidance of sunshine, photoprotection, renal insufficiency and the use of medications such as glucocorticoids, anticonvulsants, antimalarials and the calcineurin inhibitors, which alter the metabolism of vitamin D or downregulate the functions of the vitamin D receptor...

Tocilizumab (Actemra; Genentech, Inc) is the first biologic therapy targeting the cytokine interleukin 6 (IL-6). It is a humanized monoclonal immunoglobulin G1 antibody against the α-chain of the IL-6 receptor that prevents the binding of IL-6 to membrane-bound and -soluble IL-6 receptor. It was approved by the US Food and Drug Administration in January 2010 for rheumatoid arthritis refractory to other approved therapies and in April 2011 for systemic juvenile idiopathic arthritis. It has been used as an off-label treatment in many autoimmune diseases, where IL-6 plays a major role in pathogenesis...

Systemic lupus erythematosus is a chronic autoimmune disease. Treatment goals are to cure flares and to prevent them as well as long-term complications and drugs toxicity. Effort to improve patient knowledge and education should be a priority. SLE treatments range from long term prescription of antimalarial agents, to corticosteroids and, in severe cases, immunosuppressive agents. Patients should receive advice on environmental triggers and photoprotective measures. Other key points of the treatment include early prevention of atherosclerosis and infectious diseases...

Chilblain lupus or lupus pernio is a particular clinical type of cutaneous chronic lupus erythematosus, more frequently met in adults and difficult do diagnose without specific lesions at the level of the face and/or the scalp. The patient B.A., female, aged 16 is hospitalized in the Dermatological Clinic Iasi for some red-to-violaceous plaques, infiltrated, slightly scaling located around the nails and on the hands and legs finger sides. The lesions come up at the age of 13 become even more serious and painful in cold weather, getting better in the warm season when they become slightly pruriginous and are accompanied by a discrete facial erythema in "vespertilio", completely neglected by the patient...

Juvenile-onset amyopathic dermatomyositis is an uncommon variant of juvenile-onset dermatomyositis (JDM), characterized by the hallmark cutaneous features of dermatomyositis for at least 6 months without clinical or laboratory evidence of muscle disease. Cutaneous calcinosis, vasculopathy, and interstitial lung disease frequently complicate the course of classic JDM (typical JDM with myositis) but are infrequent in amyopathic JDM. Recent literature suggests that approximately 75% of amyopathic JDM patients will remain free from muscle disease after years of follow-up, while approximately 25% of patients will evolve to having classic JDM...

Cutaneous lupus erythematosus (LE) may present in a variety of clinical forms. Three recognized subtypes of cutaneous LE are acute cutaneous LE (ACLE), subacute cutaneous LE (SCLE), and chronic cutaneous LE (CCLE). ACLE may be localized (most often as a malar or 'butterfly' rash) or generalized. Multisystem involvement as a component of systemic LE (SLE) is common, with prominent musculoskeletal symptoms. SCLE is highly photosensitive, with predominant distribution on the upper back, shoulders, neck, and anterior chest...

Discoid lupus erythematosus is a chronic dermatological disease that can lead to scarring, hair loss, and hyperpigmentation changes in skin if it is not treated early and promptly. It has a prolonged course and can have a considerable effect on quality of life. Early recognition and treatment improves the prognosis. The diagnosis is usually made by clinical examination. In some cases histopathology may be required to confirm the diagnosis. The histology is that of an inflammatory interface dermatosis. There is insufficient evidence for which treatment is most effective...

BACKGROUND: Discoid lupus erythematosus (DLE) is a chronic cutaneous form of lupus erythematosus, characterized by inflammation and scarring skin lesions, with lymphocyte infiltration and vasodilation. Antimalarial drugs have beneficial therapeutic effects in DLE, partially resulting from their immunomodulating and photoprotective properties. The possible influence of these drugs on angiogenesis has not been previously evaluated. AIMS: To investigate the impact of chloroquine (CQ) treatment on the expression of vascular endothelial growth factor (VEGF, a major regulator of angiogenesis) and CD34 (a transmembrane glycoprotein expressed on endothelial cells and involved in tethering lymphocytes) in patients with DLE...

Dermatomyositis is one of the idiopathic inflammatory myopathies. It is characterized clinically by progressive symmetrical proximal muscle weakness and a characteristic rash. There are patients with rash who have little or no muscle disease. Although the process primarily attacks the skin and the muscles, it is a systemic disease with frequent manifestations in the gastrointestinal tract and pulmonary system. Dermatomyositis has been linked to internal malignancy in somewhere between 15% and 25%. Therapy for the muscle disease includes systemic corticosteroids with or without an immunosuppressive agent...

Systemic lupus erythematosus (SLE) is an autoimmune disease with a complex pathogenesis. Published data have revealed that serum levels of proinflammatory cytokines are increased in SLE patients. The aim of our study was to evaluate whether monotherapy with chloroquine phosphate affects IL-1beta, IL-6, IL-18 and TNF-alpha serum levels in SLE patients. The study group consisted of 25 SLE patients with mild or moderate disease activity and 25 age- and sex-matched healthy control subjects. In SLE patients the cytokine levels were measured just before and three months after starting chloroquine treatment at a dose of 125 mg twice daily...

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease with complex pathogenesis, various clinical presentation and chronic course with relapses. Mode of treatment depends on the disease activity and kind of internal organ involvement. In most cases clinical remission could be obtained after antimalarials, nonsteroidal anti-inflammatory drugs, corticosteroids, and photoprotection use. Despite the approved antimalarials therapeutic value, the mechanisms by which they provide benefit in lupus, patients are not fully understood...
