BACKGROUND

Long-term administration of conventional acne medications implies the potential risk of increasing microbial resistance, and safety risks. Recent interest has grown in probiotics as a potential treatment and as an adjunct for acne vulgaris.

OBJECTIVE

To conduct a systematic review of randomized controlled trials of oral probiotics in reducing the severity of acne vulgaris compared to placebo or conventional treatments.

METHODS

PubMed, Cochrane Central Register of Controlled Trials, Embase, WHO ICTRP and ClinicalTrials.gov were searched for relevant studies, and randomized controlled trials of acne vulgaris treatment with probiotic therapy were included. Outcomes include decrease in total lesion count/percent change from baseline, improvement of severity scores, inflammation related indicators, and gene expression. Changes in outcomes were calculated by effect size or pooled odds ratio.

RESULTS

A total of 2 RCTs involving 100 participants were included. Both studies show low risk on the risk bias criteria. The data of 2 RCTs reporting severity scores (AGSS and GAGS) supports that probiotics can improve their scores and thereby their condition. For inflammation-related indicators, only 1 RCT showed that probiotics can improve the IGF1 and FOXO1 gene expression in the skin. Regarding safety, only Eguren et al. reported adverse event. Their RCT showed that the incidence of adverse events was low and no serious adverse events.

CONCLUSION

In conclusion, the probiotics investigated in both studies may be given as adjuvant treatment for acne vulgaris as they improve the clinical course of patients.

BACKGROUND: To date, no multicenter studies have been conducted on the prevalence and clinical profile of AD in the Philippines. Since AD is one of the top 10 skin diseases seen in the outpatients departments of all the Philippine Dermatologic Society (PDS)- accredited institutions, conducting a multicenter study provides important epidemiological information about this disease and serve as a valuable reference for future studies.

OBJECTIVES: To determine the prevalence and clinical profile of patients with atopic dermatitis (AD) seen at the outpatient departments (OPD) of Philippine Dermatological Society (PDS) - accredited training institutions from 2007 to 2011.

METHODS: Records of patients with a diagnosis of AD seen from January 1, 2007 to December 31, 2011 were retrieved and clinical data were collected.

RESULTS: There were 744,673 dermatological consults in the 10 PDS-accredited outpatient clinics from 2007-2011. A total of 4,275 records of atopic dermatitis were reviewed for this study. The prevalence of atopic dermatitis was determined to be 0.57%. Most institutions reported a prevalence rate of less than 1% except for St. Luke's Medical Center (3.36%), and Research Institute for Tropical Medicine (7.07%). More than half of the patients (65.1%) were children between 1 to 12 years old. Twenty-four percent (24%) were infants less than one year. The average age was seven years old while the youngest was one month and the oldest was 94 years old. There were more females (56.1%) than males (42.75%). Bronchial asthma was the most prevalent co-morbid medical condition. Majority of AD patients seen in institutions were newly diagnosed. Those with previous consultations were mostly seen by dermatologists and pediatricians. Moisturizers and topical corticosteroids were the most commonly used topical preparation while antihistamines followed by oral antibiotics were the commonly prescribed oral medications. Follow-up rate was low.

CONCLUSION: The prevalence of atopic dermatitis among the 10 PDS-accredited institutions is low except for SLMC and RITM. The clinical profile of patients is consistent with published literature. However, this study revealed the patient follow-up is low. This practice needs to be addressed since optimal management of this chronic disease requires close and regular follow-up to prevent complications and irrational drug use.

Netherton Syndrome (NS) is characterized by a triad of congenital ichthyosiform erythroderma, trichorrhexis invaginata, and atopic diathesis. Diagnosis of NS poses a challenge due to its variable presentation and overlap with other dermatological conditions. Herein, we report a case of NS in a sibling pair, underscoring the challenges in diagnosis and genetic implications of this condition.

We present a case of an 8-year-old female and a 7-year-old male sibling pair, with Netherton Syndrome, who initially presented with atopic dermatitis and erythroderma without hair shaft abnormalities. Further investigation and genetic testing revealed homogeneous SPINK5 gene mutations in both patients, leading to the diagnosis of NS.

Early recognition and diagnosis of Netherton Syndrome are essential for proper management. In patients with early-onset atopic dermatitis resistant to treatment and recurrent erythroderma, further investigation is needed to exclude other diagnoses like Netherton Syndrome.
