[PMID: 35341674 DOI: 10.1016/j.jiac.2022.03.004] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 02/16/2022] [Accepted: 03/08/2022] [Indexed: 11/18/2022]
Abstract
The present guidelines aim to provide comprehensive information on genital condyloma acuminata, including the epidemiology, clinical features, diagnosis and management. The guidelines provide evidence-based recommendations on the diagnosis, prevention and treatment of genital condyloma acuminata in adults in Asia, including patients with HIV co-infection. METHODOLOGY A PubMed search was performed, using the keywords "condyloma acuminata", "anal wart", "anogenital wart", "genital wart" and "genital HPV". A total of 3031 results were found in publications during last six years. A careful review of the titles and abstracts was done to find all the studies pertaining to epidemiology, clinical features, diagnosis, treatment and prevention of condyloma acuminata. DIAGNOSIS Various diagnostic procedures described are: 1. PCR (LE: 2b). 2. Serology (LE: 2b). 3. In-situ hybridization (LE: 3). PREVENTION 1. Vaccination (LE: 1a): Quadrivalent vaccine reduced the frequency of anogenital warts in both vaccinated and unvaccinated contacts. According to the update Advisory Committee on Immunization Practices (ACIP) recommendations, the following protocol is recommended: (a). HPV vaccination at age 11 or 12 years for both males and females. (b). Catch-up vaccination for all persons through age 26 years. (c). Shared clinical decision-making regarding potential HPV vaccination for persons aged 27-45 years, who are at risk of new HPV infection. 2. Male circumcision (LE: 2a): conflicting evidence. HIV AND CONDYLOMA ACUMINATA In HIV-affected individuals, the course of HPV is more aggressive, with a greater risk of treatment resistance, increased chances of intraepithelial neoplasia as well as cancers.

Nanomedicines for the topical treatment of vulvovaginal infections: Addressing the challenges of antimicrobial resistance. Adv Drug Deliv Rev 2021; 178:113855. [PMID: 34214638 DOI: 10.1016/j.addr.2021.113855] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/24/2021] [Accepted: 06/25/2021] [Indexed: 12/11/2022]
Abstract
Recent years have, surprisingly, witnessed an increase in incidence of sexually transmitted infections (STIs). At the same time, antimicrobial therapy came under the threat of ever rising antimicrobial resistance (AMR), resulting in STIs with extremely limited therapy options. In this review, we addressed the challenges of treating vaginal infections in an era of AMR. We focused on published work regarding nanomedicine destined for localized treatment of vaginal infections. Localized therapy offers numerous advantages such as assuring high drug concentration at the infection site, limiting systemic drug exposure that can lead to faster development of AMR reduction in the systemic side effects and potentially safe therapy in pregnancy. We provided a state-of-the-art overview of nanoformulations proposed to topically treat STIs, emphasizing the challenges and advantages of each type of nanocarriers, as well as issues of potential toxicity.

Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is a common vaginal infection caused by candida species, affecting 70% of the women. It may occur due to the imbalance in the vaginal micro- biodata, pregnancy, diabetes, use of antibiotics, frequent sexual activities or AIDS. AIM The main aim of this review is to provide overview about different vaginal delivery systems for the administration of antifungal agents like conventional, mucoadhesive and muco-penetrating delivery systems. METHOD The conventional delivery systems available have limited efficacy due to the less residence time and adverse effects. In order to overcome these issues, a delivery system with mucoadhesive and muco-penetrating properties is required. Mucoadhesive polymers have excellent binding properties with mucin and thus increasing residence time. On the other hand, muco-penetrating polymers transport the antifungal agents across the mucus layer. RESULTS This review summarizes the pathophysiology of VVC along with novel delivery systems for the treatment of infection through mucoadhesive and muco-penetrating approaches. Surface modifications of nano/ microparticles with mucoadhesive or muco-penetrating particles may provide delivery systems with improved therapeutic efficacy. CONCLUSION Based on the available data, conventional and mucoadhesive drug delivery systems have some limitations, they still require improvement/ development for safe and effective delivery of antifungal agents.

Abstract
BACKGROUND Vaginal drug delivery approach represents one of the imperative strategies for local and systemic delivery of drugs. The peculiar dense vascular networks, mucus permeability, and range of physiological characteristics of the vaginal cavity have been exploited for therapeutic benefit. Furthermore, the vaginal drug delivery has been curtailed due to the influence of different physiological factors like acidic pH, constant cervical secretion, microflora, cyclic changes during periods along with turnover of mucus of varying thickness. OBJECTIVE This review highlights advancement of nanomedicine and its prospective progress towards the clinic. METHODS Relevant literature reports and patents related to topics are retrieved and used. RESULT The extensive literature search and patent revealed that nanocarriers are efficacious over conventional treatment approaches. CONCLUSION Recently, nanotechnology based drug delivery approach has promised better therapeutic outcomes by providing enhanced permeation and sustained drug release activity. Different nanoplatforms based on drugs, peptides, proteins, antigens, hormones, nucleic material, and microbicides are gaining momentum for vaginal therapeutics.

Abstract
Cervical cancer is the second most common malignant tumor in women worldwide and has a high mortality rate, especially when it is associated with human papillomavirus (HPV). In US, an estimated 12,820 cases of invasive cervical cancer and an estimated 4210 deaths from this cancer will occur in 2017. With rare and very aggressive conventional treatments, one sees in the real need of new alternatives of therapy as the delivery of chemotherapeutic agents by nanocarriers using nanotechnology. This review covers different drug delivery systems applied in the treatment of cervical cancer, such as solid lipid nanoparticles (SNLs), liposomes, nanoemulsions and polymeric nanoparticles (PNPs). The main advantages of drug delivery thus improving pharmacological activity, improving solubility, bioavailability to bioavailability reducing toxicity in the target tissue by targeting of ligands, thus facilitating new innovative therapeutic technologies in a too much needed area. Among the main disadvantage is the still high cost of production of these nanocarriers. Therefore, the aim this paper is review the nanotechnology based drug delivery systems in the treatment of cervical cancer.

Abstract
Recent studies regarding mucosal drug delivery indicate that nanosystems with surface-available polyethylene glycol (PEG) are able to penetrate mucus barrier, assure closer contact with the epithelium, and improve drug delivery to vagina. In the present work, we developed the mucus-penetrating PEGylated liposomes containing interferon alpha-2b (IFN α-2b), destined to provide localized therapy for human papilloma virus (HPV) vaginal infections. The PEGylated liposomes were of a mean size of 181±8nm, bearing a negative zeta potential of - 13mV and an entrapment efficiency of 81±10%. In vitro release experiments on model membrane showed a nearly non-existent IFN α-2b release from both the control and liposomally-associated IFN α-2b. However, the ex vivo penetration studies performed on the vaginal tissue obtained from pregnant sheep, showed the clear elevated IFN α-2b penetration from PEGylated liposomes as compared to the control. Furthermore, mucin studies confirmed the absence of interaction between the PEG-modified liposomes and mucin, confirming their ability to penetrate mucus and reach the deeper epithelium. The system holds a promise in improving topical delivery of IFN α-2b through enhanced efficacy of local anti-viral therapy.

Abstract
Although recurrent respiratory papillomatosis is a benign disease of the upper aerodigestive tract caused by infection with human papillomavirus, the disease process is unpredictable, ranging from mild disease and spontaneous remission to an aggressive disease with pulmonary spread and requirement for frequent surgical debulking procedures. It can present a protracted clinical course and cause potentially life-threatening compromise of the airways. Over recent decades, a number of alternative medical therapies to standard surgical treatment have been investigated, with modest outcomes overall. Currently, some additional therapies are being explored, together with novel surgical instrumentation that can help to avoid inevitable long-term stenotic complications, ultimately affecting quality of life. Hopefully, clinicians might soon be able to significantly improve the quality of treatment and outcomes for patients affected with recurrent respiratory papillomatosis, with human papillomavirus vaccination having a potentially important role.

Abstract
Biphasic vesicles, a novel nanostructured lipid-based delivery system show potential for topical application of interferon alpha (IFN α) for the treatment of human papillomavirus (HPV) infections (anogenital warts). Dermal delivery of IFN α encapsulated in biphasic vesicles (BPV-IFN α), applied topically to the skin, was characterized in a guinea pig model. BPV-IFN α (1g, 2 MIU/g) was topically applied either as a single or multiple treatments on the skin of guinea pigs. As a comparison with currently used regimens, IFN α solution was administered intravenously or intradermally. Skin and serum samples were collected over 96 h, IFN α levels were determined by an antiviral assay, and half-life (t₁/₂) and elimination (k) rates were calculated. Topical BPV-IFN α treatment resulted in maximum skin levels (about 100,000 U/100 cm(2)) of IFN α within 6h and maintained for 72-96 h. Clearance from the skin after intradermal injections was initially fast (t₁/₂ 0.62 h, k 1.1179 h(-1)), followed by a slower steady decrease after 6h. After intravenous and intradermal administration, IFN α was rapidly cleared from the serum, t₁/₂ 0.75 h, k 0.9271 h(-1) and t₁/₂ 1.28 h, k 0.5421 h(-1), respectively, whereas after topical application, IFN α levels remained below 100 U/mL. Topical application of BPV- IFN α resulted in sustained delivery of biologically active IFN α locally into skin with minimal systemic exposure.

Abstract
Human papillomavirus (HPV) causes benign and malignant infections of the anogenital tract. Cervical cancer, caused by high-risk HPV types 16, 18, 31, 33, 35, 45, 56 and 58, is the second most common cancer in women and the fifth most common cancer overall. Prevention and treatment of HPV infection may be revolutionized using nanotechnology tools such as vaccines based on virus-like particles and nanoscale drug-delivery systems. Advances in both virus-like particle design and noninvasive delivery of antiviral protein drugs, such as IFNalpha, may provide new opportunities to take on the challenge of global elimination of HPV infections. Biphasic vesicle cream formulation, representing a new class of dermal delivery system for protein drugs, is an alternative to injectable dosage form to deliver IFNalpha for the treatment of HPV infections, showing efficacy in low-grade squamous epithelical lesions of the cervix.
