Nail the diagnosis: Lamivudine-induced periungual pyogenic granulomas in PLHIV.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Pyogenic granuloma (PG), also known as lobular capillary haemangioma, is a benign vascular proliferation that typically presents as friable, red, pedunculated papules on the skin or mucous membranes. Multiple periungual pyogenic granulomas, a unique entity within cutaneous pyogenic granulomas, most frequently occur in association with medications, including antiretroviral drugs. Clinical case: A 30-year-old male living with HIV presented with painful, progressively enlarging ulcero-proliferative lesions on the fingertips and toes, occurring 12 months after initiating highly active antiretroviral therapy (HAART) comprising Tenofovir disoproxil (300 mg), Lamivudine (300 mg), and Dolutegravir (50 mg). Examination revealed haemorrhagic, friable granulation tissue over the nail folds and paronychial areas of multiple digits. Systemic examination was unremarkable. Differential diagnoses included drug-induced PG, bacillary angiomatosis, Kaposi sarcoma, and cutaneous angiosarcoma. A biopsy confirmed the diagnosis of PG. Bartonella serology and tissue polymerase chain reaction (PCR) were negative, ruling out bacillary angiomatosis. Histopathology showed no features suggestive of Kaposi sarcoma or angiosarcoma. Among ART agents, lamivudine and indinavir have been most frequently associated with periungual PGs. The patient showed minimal improvement with topical corticosteroids, antibiotics, and debridement. Lamivudine was subsequently discontinued and ART was modified, leading to near-complete resolution of lesions over six months-supporting a diagnosis of lamivudine-induced periungual PG. Conclusion: Periungual pyogenic granulomas can lead to significant discomfort and functional impairment. This case highlights the potential role of lamivudine as a causative agent and underscores the importance of ART modification in the effective management of drug-induced PG.
