Abstract
INTRODUCTION Pityriasis lichenoides chronica is the chronic end of the spectrum of pityriasis lichenoides which have several forms of papulosuamous conditions. Several treatments obtained complete clearance of the condition including phototherapy and specifically narrow band ultraviolet B. The Excimer light 308 is a monochromatic light that acts within the ultraviolet B wavelength and used as a targeted phototherapy in several skin conditions. METHODS Thirty-four patients with histopathologically diagnosed pityriasis lichenoides chronica underwent treatment with biweekly sessions of excimer light 308 nm. Treatment continued until complete clearance was obtained or to a maximum of 48 sessions (24 weeks). RESULTS Thirty-one patients obtained complete clearance with no recurrence till the end of the study period, two patients had partial response and only one patient showed poor response to treatment. CONCLUSION Excimer light can be a safe and effective treatment of pityriasis lichinoides chronica in different ages and genders.

Abstract
INTRODUCTION Pityriasis lichenoides (PL) is a papulosquamous disease affecting both children and adults, for which narrowband-UVB (NB-UVB) phototherapy is regarded as a commonly used treatment option. The aim of this study was to investigate the efficacy of NB-UVB phototherapy in the management of PL and to compare response rates in pediatric and adult age groups. MATERIALS AND METHODS This observational, retrospective study included 20 PL patients (12 pityriasis lichenoides chronica; PLC, 8 pityriasis lichenoides et varioliformis acuta; PLEVA) who failed to respond to other treatment modalities. The data for this study were collected retrospectively from patient follow-up forms in the phototherapy unit. RESULTS A complete response (CR) was obtained in all pediatric patients with PL, while 53.8% of adult patients had achieved CR. The mean cumulative dose required to achieve the CR was higher in pediatric patients than adult patients with PL (p < .05). The CR was achieved in 6 (75%) of 8 PLEVA patients, while 8 (66.7%) of 12 PLC patients had reached to CR. The mean number of exposures for patients with PLC to achieve a CR was higher than patients with PLEVA (p < .05). Erythema was the most common adverse effect during phototherapy particularly in 5 (35.7%) of the patients with PL who had achieved CR. CONCLUSIONS NB-UVB is an effective and well-tolerated treatment option for PL especially in diffuse types. A higher response can be obtained in children with higher cumulative dose. Patients with PLC may require more exposures for CR than patients with PLEVA.

Role of streptococcal infection in the etiopathogenesis of pityriasis lichenoides chronica and the therapeutic efficacy of azithromycin: a randomized controlled trial.

[PMID: 36129521 PMCID: PMC10020249 DOI: 10.1007/s00403-022-02398-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 12/02/2021] [Accepted: 09/07/2022] [Indexed: 11/24/2022]
Abstract
The exact aetiology of pityriasis lichenoides chronica (PLC) remains unknown. While phototherapy is the most investigated therapeutic modality, azithromycin has been used scarcely. The aim of this study is to evaluate the therapeutic efficacy of azithromycin in the treatment of PLC compared to NB-UVB and evaluating the presence of streptococcal infection as a possible etiological factor in PLC patients. The study was designed as a randomised controlled trial. Twenty-four patients with PLC were randomly allocated into either azithromycin (n = 13, standard dose every 10 days) or NB-UVB (n = 11, thrice weekly) groups. End of study (EOS) was either complete clearance of lesions or a maximum of 8 weeks. Therapeutic efficacy was defined as percent reduction in lesions and was calculated for the rash as a whole, erythematous papules alone, and hypopigmented lesions alone and graded into complete, very-good, good, poor or no response. Anti-streptolysin O titre (ASOT), anti-deoxyribonuclease B titre (anti-DNaseB) and throat culture were evaluated at day 0. No significant difference existed between both groups as regards therapeutic efficacy. At EOS, NB-UVB achieved significantly more percent reduction in the extent of hypopigmented lesions and consequently in the rash as a whole (p = 0.001, p = 0.034, respectively). The extent of the rash as a whole was significantly less in the NB-UVB at EOS (p = 0.029, respectively). The effect of NB-UVB on hypopigmented lesions appeared early at week 4 of treatment. Only two patients, one from each group, relapsed during the 3 month follow-up. Evidence of recent streptococcal infection was present in 79% of the cases, mainly in the form of elevated ASOT (94.7%). It was significantly more encountered in young children (< 13 years) (p = 0.03) and was associated with more extent of erythematous papules and consequently with more extent of the rash as a whole (p = 0.05 and p = 0.01, respectively). It did not affect outcome of therapy at EOS. Azithromycin did not show more favorable response in patients with recent streptococcal infection. Therapeutic efficacy of azithromycin is comparable to NB-UVB in treatment of PLC; however, NB-UVB is superior in management of hypopigmented lesions. It is highly suggested that PLC could be a post streptococcal immune mediated disorder.Registration number: ClinicalTrials.gov, NCT03831269.

Abstract
Post-inflammatory hypopigmentation is a common acquired pigmentary disorder that is more prominent in skin of color, leading to great cosmetic and psychosocial implications. Often, a diagnosis with a pigmentary disorder can negatively impact an individual's health-related quality of life and may result in stigma. Although most cases of post-inflammatory hypopigmentation resolve spontaneously over time, a systematic diagnostic approach can help with identifying the underlying etiology and informing treatment strategies. It can be due to cutaneous inflammation, sequelae of inflammatory or infectious dermatoses, or dermatologic procedures. Therefore, a thorough understanding of the epidemiology, patient history, physical exam findings, and clinical features of post-inflammatory hypopigmentation phenomenon can explain the primary cause to providers and allow for patient education. It is also important to understand the various therapeutic approaches available and the efficacy of these options, which will inform providers to choose the appropriate therapy for patients. Although algorithms exist for classifying acquired disorders of hypopigmentation, there are no established algorithms for the diagnosis and treatment of post-inflammatory hypopigmentation, which warrants further exploration and discourse.

Abstract
Since the introduction of modern phototherapy in 1903 by Nobel Prize-winner Niels Ryberg Finsen, the usage of this therapy in the medical field has grown, techniques have been refined and developed, and it has gained widespread acceptance. Psoriasis vulgaris, parapsoriasis, lichen planus, atopic dermatitis, neonatal jaundice, urticaria, morphea, vitiligo, granuloma annulare and cutaneous T cell lymphoma are only a few dermatological indications that come along with satisfactory results. Most often, it is a 2nd or 3rd line therapy being an alternative in more severe or refractory diseases. Despite the side effects that may occur after phototherapy, which are often minor, the benefits can be significant. Unfortunately, the absolute contraindications limit the use of this type of treatment and implicitly the management of these patients. The current review aimed to combine the recommendations of phototherapy in dermatology, the types of phototherapy that can be suitable for certain dermatological diseases and to emphasize its importance in certain conditions that are associated with significant remission rates.

Abstract
BACKGROUND Pityriasis lichenoides (PL) is a papulosquamous dermatosis affecting both children and adults, for which no standard treatment currently exists. OBJECTIVES To characterize different treatment options and develop an evidence-based treatment algorithm for PL. METHODS A systematic search of published literature on PL treatments was performed on 23 December 2017 via the MEDLINE, Embase, CINAHL, CENTRAL, ClinicalTrials.gov and the EU Clinical Trials Register databases. RESULTS Of 1090 abstracts retrieved, 27 full-text articles with 502 participants were included for analysis. Seventeen of the full-text articles were retrospective cohort studies and two were randomized controlled studies. Treatment modalities included in these articles were phototherapy, antibiotics, methotrexate, pyrimethamine and trisulfapyrimidine, corticosteroids and conservative treatment. Of these treatments, phototherapy led to complete remission in the highest proportion of patients, and topical corticosteroids were found to have been trialled in the highest number of patients. CONCLUSIONS The current literature consists almost entirely of uncontrolled studies, and none provides compelling data to support an evidence-based approach to PL treatment. Pityriasis lichenoides chronica and pityriasis lichenoides et varioliformis acuta should be distinguished in response to treatment, and definitions of response to treatment must be standardized. Additional randomized control studies with longer follow-up will help better differentiate between treatment efficacies and adverse effects.

Abstract
Pityriasis lichenoides chronica (PLC) is an infrequent dermatosis of unknown aetiology, wholse evolution and response to treatment differs between children and adults. When PLC is recalcitrant or unresponsive to topical treatment, phototherapy is one of the main treatments used. We carried out a prospective study of adult diffuse PLC treated with narrowband ultraviolet B (NB-UVB). We treated eight patients whose disease showed no response to topical therapy, and obtained a complete response rate of 88% in a mean of 23 sessions (cumulative dose 16.99 J/cm2 ). However, the relapse rate was 43% in the first 6 months. Our results are similar to those of other published studies but there is much variability between them in the doses applied and the number of sessions needed. Further studies are necessary to devise a protocol for NB-UVB treatment of PLC.

Abstract
Pityriasis lichenoides is a benign disease that includes a continuous spectrum with two polar ends: pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC). Although its benign and self-limited character, treatment is required, both for itch relief and for cosmetic issues. The present study is a retrospective analysis of 13 patients (11 PLC and 2 PLEVA) treated in our institution with psoralen plus ultraviolet A (PUVA) or ultraviolet A combined with ultraviolet B (UVA/UVB) during the period 1998-2011. In the PUVA group, complete response was achieved in five patients and partial response in two. Total cumulative UVA dose was 84.4 J/cm(2). One patient quit therapy without therapeutic response. In the UVA/UVB group, complete response was achieved in two patients and partial response in an equal number of patients. One patient did not reach a significant improvement. Total cumulative doses were: 26.1 J/cm(2) for UVA and 3.62 J/cm(2) for UVB. There were no acute side effects in either therapeutic group. In the present study, PUVA phototherapy was preferred for patients with more widespread or long-evolving disease, while UVA/UVB was selected for patients who presented more recent disease or contraindications for PUVA therapy. Regardless of the absence of clinical guidelines, both therapeutic options proved to be successful, ascertaining phototherapy as an effective and safe option for pityriasis lichenoides patients.

Abstract
BACKGROUND Current knowledge about the efficacy of narrowband UVB therapy for the treatment of pityriasis lichenoides is limited. OBJECTIVE The aim of this study was to investigate the efficacy of narrowband UVB therapy for the treatment of pityriasis lichenoides chronica (PLC). METHODS Data were retrospectively collected following a review of patient phototherapy and medical charts, and telephone interviews were performed for follow-up information. RESULTS The study included 25 patients (14 male, 11 female) with a mean age of 34 +/- 13 years. Diagnosis was confirmed by histopathological examination in 92% (n = 23) of the patients. The median duration of the disease was 24 months (range: 2-192 months). The median number of sessions until response was 25 (8 weeks) (range: 9-77 sessions), with a median cumulative dose of 15 J/cm(2) (range: 2-158 J/cm(2)). Complete response and partial response were achieved in 48% and 44% of the patients, respectively, while 8% of the patients achieved no response. In those patients for whom follow-up data were available (n = 17), 10 (58%) relapsed within a median of 9.5 months (range: 1-44 months). CONCLUSIONS Our results suggest that narrowband UVB is an effective and well-tolerated treatment option for PLC.
