Effectiveness and safety of 0.5% timolol solution in the treatment of pyogenic granuloma: A randomized, double-blind and placebo-controlled study

Introduction: Pyogenic granulomas are benign vascular lesions of the skin and mucosa which are often a source of concern because of their recurrent bleeding even with minimal trauma. Current treatment for pyogenic granuloma is ablative; no medical therapy is standardized to date. Timolol, due to its vasoconstrictive effect, vascular growth factor inhibition and apoptosis promotion properties, is a potential therapeutic option. Objectives: To assess the effectiveness and safety of topical timolol in the treatment of pyogenic granulomas. Methods: A two-centre, double-blind and placebo-controlled trial (Registration CTRI/2019/04/018581) was conducted. Patients of either sex were recruited with pyogenic granuloma lesions of less than eight weeks duration. Topical treatment with 0.5% timolol or matching glycerin placebo was continued for six weeks. Changes in color, size, bleeding tendency, physicians’ and patients’ global assessments and adverse events were assessed. Results: Forty subjects were randomized between the two groups which were comparable in age, sex, duration of illness and baseline lesion size.Significant improvement was noted with timolol, with color change from first follow-up onwards and lesion size reduction from second follow-up onward. Patients’ assessment of bleeding tendency also showed imrovement from the second visit onward. Between-group comparison showed significant difference with respect to percentage reduction in size (timolol 40.9%, placebo 3.4%; P = 0.002). Rescue treatment (electrosurgery) was required in five patients on placebo and in one in the timolol group (P = 0.182). Complete resolution occurred in 2 (10%) patients with timolol and in no patients on placebo (P = 0.231). Limitations: We observed effects of treatment for only six weeks. Conclusion: Topical timolol may be a treatment option for early pyogenic granulomas but complete resolution is unlikely in six weeks. Studies of longer duration are required to assess resolution and recurrence rates

A double-blind, randomized controlled trial to compare the effectiveness and safety of purified protein derivative of tuberculin antigen with Mycobacterium w vaccine in the treatment of multiple viral warts

Background: Present day therapeutic modalities for viral warts are mostly ablative in nature, limited by high recurrence rates and are unsuitable for numerous lesions. Immunotherapy has the potential to overcome these limitations. Aims: This study aimed at comparing efficacy and safety of and quality of life changes with intradermal purified protein derivative (PPD) of tuberculin antigen and Mycobacterium w (Mw) vaccine in immunotherapy of warts. Methods: Patients with multiple (≥5) warts were randomized (1:1) into two groups (PPDand, Mw vaccine groups). Fortnightly, 0.1 ml of either medicine was injected intradermally over the deltoidregion till complete resolution or a maximum of six doses. Patients were followed-up for another 3 months for recurrence. Results: Sixty-four participants received either PPD or Mw vaccine. The number of warts were comparable at baseline (P = 0.089, Mann–Whitney test), and reduced significantly with treatment in both groups (P < 0.001, Friedman's ANOVA), as seen from the fourth follow-up onwards with Mw and fifth follow-up onwards with PPD (P < 0.05, Post hoc Dunn's test). Intergroup comparison showed significantly more (P < 0.05, Mann–Whitney test) reduction with Mw than PPD at the sixth and seventh follow-up. The size of warts also reduced significantly (P < 0.001) in both groups from the third follow-up onwards. Complete remission was more (P = 0.539, Fischer's exact test) in the Mw group (68.8%) than the PPD group (50%); and was significantly higher (P = 0.049, Mann–Whitney test) in patients having shorter duration of warts. Adverse events were significantly more (P < 0.001) with Mw including ulceration (50%), discharge (15.6%), pain-swelling-induration and scar at the injection site (97% each), whereas some of those receiving PPD noted erythema and scaling at the injection site (18.8%), and post-inflammatory hyperpigmentation (12.5%). No recurrence was seen till the end of the study. Limitation: Unicentric trial. Conclusion: Intradermal injection of Mw vaccine was more effective but had a higher incidence of adverse effects compared to PPD of tuberculin antigen in patients with warts.

A randomized, double-blind trial of amorolfine 0.25% cream and sertaconazole 2% cream in limited dermatophytosis

Background: Dermatophytosis is becoming increasingly unresponsive to conventional antifungals. Newer topical antifungals may be more effective in these patients. Aims: To evaluate and compare the efficacy and safety of amorolfine 0.25% cream and sertaconazole 2% cream in limited tinea cruris/corporis. Methods: A single-center, randomized (1:1), double-blind, parallel group, active-controlled trial (CTRI/2014/12/005246) was performed. Sixty-six untreated adults with acutely symptomatic tinea cruris/corporis were included in the study. All patients had limited cutaneous involvement and were KOH mount positive. Group A received amorolfine 0.25% cream, and group B received sertaconazole 2% cream twice daily application to the lesions for 4 weeks. After the baseline visit, four follow-up visits were carried out. The outcome measures for effectiveness were clinical and mycological cure. Safety parameters studied were treatment-emergent adverse events and changes in routine laboratory parameters. Results: Both sertaconazole and amorolfine significantly reduced symptoms (P < 0.001) in both groups. However, improvement in symptoms (pruritus, burning sensation, erythema, scaling and crusting) was significantly greater in the sertaconazole group at every follow-up visit. Sertaconazole cream was also more effective than amorolfine cream in reducing the number of lesions (P = 0.002 at 12 weeks) and improving the Dermatology Life Quality Index (P < 0.001) at all the follow-up visits. Adverse events were similar in the two groups (P = 0.117). Fungal cultures became negative in 92.3% of the sertaconazole group as compared to 80% in the amorolfine group (P = 0.010). Limitations: Antifungal susceptibility testing could not be done. Conclusion: Sertaconazole 2% is superior to amorolfine 0.25%, both in terms of effectiveness and tolerability. Improvement can be appreciated from second week onwards.

Safety and effectiveness of autoinoculation therapy in cutaneous warts: A double - blind, randomized, placebo - controlled study.

Background: In spite of the availability of multiple treatment options, viral warts are known for their persistence and recurrence, causing frustration to patients and treating physicians. Aims: To study the effectiveness and safety of autoinoculation as a treatment modality in cutaneous warts. Methods: A double‑blind, placebo‑controlled study was carried out. In the treatment group, full‑thickness warty tissue was excised, minced and implanted in a small dermal pocket. In the control group, warty tissue was only excised and not implanted, though a dermal pocket was made. Patients were evaluated every four weeks with lesion counts. The procedure was repeated at 4 and 8 weeks. Response was assessed at each visit and at 12 weeks. Results: Forty‑eight patients with cutaneous warts (male: female = 32:16) were randomized into autoinoculation and control groups. The number of warts at baseline was comparable in both groups (P = 0.293). Reduction in the number of warts was significantly more in the autoinoculation group (8.50 ± 13.88) than in the control group (10.04 ± 5.80) from 8 weeks onwards (P = 0.010). Complete resolution occurred only in the autoinoculation group, in 62.5% of cases. Adverse effects were seen in 11 patients, including infection of the donor site (5 cases), keloid formation (3) and hypopigmentation (3). Conclusion: Autoinoculation may be an effective therapeutic modality for cutaneous warts and two sessions may be required for optimum results.
