Effect of Solanum Melongena Extract in the Treatment of Arsenical Skin Lesion

July 12, 2018 updated by: Prof. Mir Misbahuddin, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh
Solanum melongena is a common vegetable contains phytochemicals which prevent, reduce or delay the oxidation of DNA and alter the cellular signal transduction pathways controlling cell proliferation and apoptosis of human cancer. The skin of Solanum melongena peel contains nasunin an anthocyanins and chlorogenic acid which have anti-inflammatory, antioxidant, antimutagenic and antiangiogenic properties. Extract of Solanum melongena is used in actinic keratosis and Squamous cell carcinoma of the skin. This study will determine any change in arsenical skin lesion after administrating Solanum melongena extract cream.

Detailed Description

Bangladesh is grappling with the world greatest ever environmental health disaster in history. About three decades, more than thirty millions people subsistence with this problem without any potential treatment. So, now arsenic crisis as a major issue and becomes a demand of era to find out the way to solve this problem. Chronic ingestion of arsenic contaminated water is a silent killer of the human because even it may cause death by carcinoma. Arsenic has an affinity to keratin-rich tissue like skin, hair, nail due to the presence of sulphydryl group, as a consequence, they manifest of clinical symptoms like hyperpigmentation or melanosis, diffuse dark brown spot of skin or characteristic rain drop appearance over the trunks, limbs; keratosis. Even due to prolong exposure to arsenic e.g. invasive skin lesion as Bown's disease and squamous cell carcinoma appear. Arsenic as neglected disease arsenic patients has no established treatment except preventive and supportive treatment of melanosis by drinking arsenic free water and salicylic acid as keratolytic substance. But the malignant condition of arsenic skin lesion treatment is not yet documented. Solanum melongena belongs to Leptostemonum Clade (the "spine" solanums) species-rice in solanaceae. It also called brinjal or eggplant. Solanum melongena is a common vegetable contains phytochemicals which prevent, reduce or delay the oxidation of DNA and alter the cellular signal transduction pathways controlling cell proliferation and apoptosis of human cancer. Polyphenols of Solanum melongena exhibit an anticancer effect both in vitro and in vivo experiments. Polyphenol reduces scavenge free radicals, induce apoptosis, inhibit cell proliferation and angiogenesis and exhibit phytoestrogen activity. On other hand, they suppress the NF-κB and the activating protein (AP-1), inhibit the mitogen-activated proteins (MAPKs), the protein kinase and growth factor receptor-mediated pathways which are involved in cell cycle arrest and possess anti-inflammatory properties. Solanum melongena has solasodine glycoalkaloids which are cytotoxic and bind with endogenous endocytic lectin of cancer cell membrane and induce apoptosis and cell death both in vivo and in vitro. The skin of Solanum melongena peel contains nasunin an anthocyanins and chlorogenic acid which have anti-inflammatory, antioxidant, antimutagenic and antiangiogenic properties. It has a cytotoxic effect on brine shrimp. Therefore, this study will be conducted to determine is there any change in the patient with arsenical skin lesions before and after application of topical Solanum melongena extract cream. Twenty-five patients with arsenical skin lesions will be recruited on the basis of inclusion and exclusion criteria after IRB approval. The patients will be applied Solanum melongena extract cream twice daily for 12 weeks without any interruption. Water and nails samples will be collected for confirming the diagnosis. Blood samples will be collected before and after treatment to evaluate the liver and renal function tests. So, this study will determine any change in arsenical skin lesion after administrating Solanum melongena extract cream.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
