Acne vulgaris (AV) is a chronic skin disease of the pilosebaceous unit affecting both adolescents and adults. Its pathophysiology includes processes of inflammation, increased keratinization, sebum production, hormonal dysregulation, and bacterial Cutibacterium acnes proliferation. Common AV has been treated with antibiotics since the 1960s, but strain resistance has emerged and is of paramount concern. Macroalgae are known producers of substances with bioactive properties, including anti-viral, antibacterial, antioxidant, and anti-inflammatory properties, among several others. In particular, red algae are rich in bioactive compounds such as polysaccharides, phenolic compounds, lipids, sterols, alkaloids, and terpenoids, conferring them antioxidant, antimicrobial, and anti-inflammatory activities, among others. Thus, the exploration of compounds from marine resources can be an appealing approach to discover new treatment options against AV. The aim of this work is to provide an overview of the current knowledge of the potentialities of red macroalgae in the treatment of AV by reviewing the main therapeutic targets of this disease, and then the existence of compounds or extracts with bioactive properties against them.

Acne is an inflammatory skin disorder; although some anti-inflammatory medicines for treating acne are available in a market, they have considerable side effects; therefore, new treatment options are needed. In the present study, among the 16 aqueous extracts of plants collected from Jeju Island in Korea which are used to test anti-inflammatory activity, B. davidii showed the strong decline of the proinflammatory cytokine expression against the inflammatory process caused by C. acnes in Human HaCaT keratinocyte cells. B. davidii downregulated the expression of 57% of COX-2, 41% of iNOS, and proinflammatory cytokines 29% of TNF-α, 32% of IL-1β, 21% of IL-6, and 35% of IL-8. Furthermore, B. davidii inhibited NF-κB and MAPK signaling cascades in keratinocytes that activated by toll-like receptor 2 (TLR-2) in response to C. acnes. Given those results, B. davidii is a potential agent to reduce the proinflammatory cytokine expression against C. acnes-induced inflammation and might provide an alternative to the current medications.

Sargassum Miyabei

Acne vulgaris is a chronic inflammatory condition of skin sebaceous follicles. To explore its effects on acne vulgaris, we investigated the antibacterial and anti-inflammatory activities of Sargassum miyabei Yendo (a brown alga) ethanolic extract (SMYEE) on Cutibacterium acnes (C. acnes)-stimulated inflammatory responses, both in vivo and in vitro. To induce inflammation in vivo, C. acnes was intradermally injected into the dorsal skin of mice, to which SMYEE was applied. The antimicrobial activity of SMYEE was evaluated by the determination of minimum inhibitory concentrations (MICs). To explore in vitro anti-inflammatory effects, HaCaT cells were stimulated with C. acnes after treatment with SMYEE. The levels of IL-8 and the underlying molecular effects in C. acnes-stimulated HaCaT cells were assessed by enzyme-linked immunosorbent assay, Western blotting, and an electrophoretic mobility shift assay. Mouse skin lesions improved after treatment with SMYEE (50 μg/mouse). Neutrophil infiltration was significantly reduced in SMYEE-treated compared to SMYEE-untreated skin lesions. SMYEE reversed the C. acnes-induced increase in IL-8 levels in HaCaT cells and suppressed dHL-60 cell migration. SMYEE also inhibited C. acnes-induced phosphorylation of the extracellular signal-regulated kinase and inhibited activator protein-1 signaling. SMYEE may be a useful treatment for C. acnes-induced acne vulgaris.

Background: Cutibacterium acnes has been identified as one of the main triggers of acne. However, increasing knowledge of the human skin microbiome raises questions about the role of other skin commensals, such as Staphylococcus epidermidis, in the physiopathology of this skin disease. Summary: This review provides an overview of current knowledge of the potential role of S. epidermidis in the physiopathology of acne. Recent research indicates that acne might be the result of an unbalanced equilibrium between C. acnes and S. epidermidis,according to dedicated interactions. Current treatments act on C. acnesonly. Other treatment options may be considered, such as probiotics derived from S. epidermidis to restore the naturally balanced microbiota or through targeting the regulation of the host’s AMP mediators. Key Messages: Research seems to confirm the beneficial role of S. epidermidis in acne by limiting C. acnes over-colonisation and inflammation.

Chronic Skin Disease

Acne vulgaris is a chronic skin disease of the pilo-sebaceous unit and develops due to blockages in the skin's hair follicles. It is characterized by blackheads or whiteheads, pimples, oily skin, and possible scarring It primarily affects areas of the skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. These blockages are thought to occur as a result of the following four abnormal processes: a higher than normal amount of oily sebum production (influenced by androgens), excessive deposition of keratin protein leading to comedo formation, colonization of the follicle by Cutibacterium acnes (C. acnes) bacteria, and the local release of pro-inflammatory chemicals in the skin. The resulting appearance can lead to anxiety, reduced self-esteem and, in extreme cases, depression or suicidal thoughts. In  Ayurveda, it is termed as Mukhadushika. In Ayurveda, Mukhadushika is described under the heading of Kshudra rogas. These diseases are called as Kshudra because of their lesser severity. According to Sushruta Samhita Nidan Sthana, these are Shalmali thorn like eruption found on the face of adolescents are called as Mukhadushika or Yuvan Pidika. These are impregnated with Meda. Vitiated Vata Dosha, Kapha Dosha and Rakta Dosha are considered to be the main Samprapti Ghatak of Mukhadushika. In Ayurveda treatment of diseases is mainly of two types of Chikitsa are described i.e. Shodhana Chikitsa and Shamana Chikitsa. Similarly in Mukhadushika also Shodhana and Shamana Chikitsa is done.

Acne vulgaris is a highly prevalent skin disorder requiring treatment and management by dermatologists. Antibiotics such as clindamycin are commonly used to treat acne vulgaris. However, from both medical and public health perspectives, the development of alternative remedies has become essential due to the increase in antibiotic resistance. Topical therapy is useful as a single or combined treatment for mild and moderate acne and is often employed as maintenance therapy. Thus, the current study investigated the anti-inflammatory, antibacterial, and restorative effects of sesquiterpene farnesol on acne vulgaris induced by Cutibacterium acnes (C. acnes) in vitro and in a rat model. The minimum inhibitory concentration (MIC) of farnesol against C. acnes was 0.14 mM, and the IC50 of 24 h exposure to farnesol in HaCaT keratinocytes was approximately 1.4 mM. Moreover, 0.8 mM farnesol exhibited the strongest effects in terms of the alleviation of inflammatory responses and abscesses and necrotic tissue repair in C. acnes-induced acne lesions; 0.4 mM farnesol and clindamycin gel also exerted similar actions after a two-time treatment. By contrast, nearly doubling the tissue repair scores, 0.4 mM farnesol displayed great anti-inflammatory and the strongest reparative actions after a four-time treatment, followed by 0.8 mM farnesol and a commercial gel. Approximately 2–10-fold decreases in interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α, found by Western blot analysis, were predominantly consistent with the histopathological findings and tissue repair scores. The basal hydroxypropyl methylcellulose (HPMC) gel did not exert anti-inflammatory or reparative effects on rat acne lesions. Our results suggest that the topical application of a gel containing farnesol is a promising alternative remedy for acne vulgaris.

The bacterial species Cutibacterium acnes (formerly known as Propionibacterium acnes) is tightly associated with humans. It is the dominant bacterium in sebaceous regions of the human skin, where it preferentially colonizes the pilosebaceous unit. Multiple strains of C. acnes that belong to phylogenetically distinct types can co-exist. In this review we summarize and discuss the current knowledge of C. acnes regarding bacterial properties and traits that allow host colonization and play major roles in host-bacterium interactions and also regarding the host responses that C. acnes can trigger. These responses can have beneficial or detrimental consequences for the host. In the first part of the review, we highlight and critically review disease associations of C. acnes, in particular acne vulgaris, implant-associated infections and native infections. Here, we also analyse the current evidence for a direct or indirect role of a C. acnes-related dysbiosis in disease development or progression, i.e., reduced C. acnes strain diversity and/or the predominance of a certain phylotype. In the second part of the review, we highlight historical and recent findings demonstrating beneficial aspects of colonization by C. acnes such as colonization resistance, immune system interactions, and oxidant protection, and discuss the molecular mechanisms behind these effects. This new insight led to efforts in skin microbiota manipulation, such as the use of C. acnes strains as probiotic options to treat skin disorders.

Background: Acne is the eighth most prevalent disease affecting 9.4% of the population worldwide and its prevalence in our country is estimated to be around 5%. Severe inflammatory acne is most likely to leave scars and in order to prevent facial disfigurement due to acne scarring, early treatment is desirable. Various treatment options have been formulated for acne, and are tailored according to the severity of the disease. Numerous clinical trials have been conducted till now, to determine the usefulness and side effect profile of such therapies, making acne treatment a highly studied area in dermatology. Objective of this study is to highlight the fact that oral Dapsone could be used as a cheaper alternate to isotretinoin in recalcitrant severe acne, especially in females where retinoids are sometimes contraindicated. Patients and methods: 51 patients, suffering from severe nodulocystic acne, fulfilling the criteria, were enrolled from the Department of Dermatology, Sir Ganga Ram Hospital, Lahore. All the study patients were given oral Dapsone 50mg for initial two weeks and then 100mg daily for the next 10 weeks along with oral cimetidine and topical clindamycin application twice daily. Investigator Global Assessment Scale (IGAS) was employed to measure effectiveness. The treatment was considered ʽeffectiveʹ if the patient achieves 2 or more than 2-grade improvement or almost clear or clear skin at the end of 12 weeks according to IGAS scale. The lesion counts were also done before the start of therapy (day 1) and at every two weeks follow up for 12 weeks. The change in lesion count observed between the baseline number and that seen at follow up visits was also used to evaluate the effectiveness of oral Dapsone. Safety was analyzed by fortnightly visits of the patients to look for any undesirable side effects and monitoring of the hematologic profile of the patients. Final follow up was done at the end of 16 weeks. Results: The study was conducted on 51 patients, with a ratio of 1:3 for males and females and a mean age of 25.2 years (SD ±5.81). At 12th week, patients had significant reduction in their acne lesions; with 7 patients (13.7%) showing completely clear skin, 17 patients (33.3%) had almost clear skin, 5 patients (9.8%) had 3-grade improvement. Twelve patients (23.5%) had 2-grade improvement from baseline score and only 2 patients (3.9%) had 1-grade improvement from baseline. Based on percentage reduction of lesions, excellent response was seen in 32 patients (62.7%), good response in 9 patients (17.6%), moderate response in 2 patients (3.9%), while no patient showed poor response. Dapsone was discontinued in 8 patients due to derangement of hematologic profile. Conclusion: Oral Dapsone, when given carefully, is a very effective therapeutic option in severe recalcitrant acne, with limited side effects.

Peripheral Spondyloarthritis

: Interstitial lung disease (ILD) is the most common form of pulmonary impairment in patients with rheumatoid arthritis (RA). However, patients with RA or other arthritic diseases such as psoriatic arthritis (PsA) or peripheral spondyloarthritis (pSpA) may develop several other pulmonary diseases such as chronic obstructive lung disease (COPD) with a higher risk than patients without arthritis. The article at hand aims at summarizing the current knowledge on the prevalence of pulmonary diseases in the above-mentioned forms of arthritis, the challenges for prevalence studies and detecting pulmonary diseases in patients with arthritis as well as possible treatment options. Dyspnea, cough or other pulmonary symptoms or findings in arthritis patients should prompt gradual diagnostic procedures considering pulmonary manifestations as a major cluster of differential diagnosis. Considering its poor prognosis and morbidity burden, RA-ILD needs to be ruled out. Treatment of manifestations often lacks solid evidencebased guidelines and referrals to specialized centers are often necessary.

Neuroendocrine neoplasias (NENs) are a heterogeneous group of rare tumors scattered throughout the body. Surgery, locoregional or ablative therapies as well as maintenance treatments are applied in well-differentiated, low-grade NENs, whereas cytotoxic chemotherapy is usually applied in high-grade neuroendocrine carcinomas. However, treatment options for patients with advanced or metastatic NENs are limited. Immunotherapy has provided new treatment approaches for many cancer types, including neuroendocrine tumors, but predictive biomarkers of immune checkpoint inhibitors (ICIs) in the treatment of NENs have not been fully reported. By reviewing the literature and international congress abstracts, we summarize the current knowledge of ICIs, potential predicative biomarkers in the treatment of NENs, implications and efficacy of ICIs as well as biomarkers for NENs of gastroenteropancreatic system, lung NENs and Merkel cell carcinoma in clinical practice.
