Two patients with HIV disease developed a pruritic, maculo-papular rash shortly after introducing an association of 2 protease inhibitors (PI) lopinavir/ritonavir (Kaletra). The dermatitis started respectively 7 and 10 days after taking Kaletra, improved on withdrawal, and relapsed following its reintroduction. Although itchy, the dermatitis was not life-threatening, and the patients were treated "through the rash" without suspending the drug. Histopathologic examination of lesional skin showed a non-specific inflammatory infiltration consisting of neutrophils and lymphocytes, but there were no eosinophils, nor dilatation of capillaries in the papillary dermis. HIV positive patients are more prone to drug-related rashes than the general population. Awareness of the side-effects of PI plays an important role in keeping compliance with the treatment and helps patients reach their goal in controlling the development of HIV. The safety profile of Kaletra and its cutaneous side effects have yet to be completely elucidated.

Background: Few studies have analysed oxaliplatin-induced adverse events (ADEs) in the immune system and skin and subcutaneous tissues through pharmacovigilance. We used this approach to analyse the risk of such ADEs when oxaliplatin combined with immune checkpoint inhibitors (ICIs).
Methods: We evaluated the association between oxaliplatin and ADEs in the immune system and skin and subcutaneous tissues using the reporting odd ratio (ROR) for mining the ADE report signals in the FDA Adverse Event Reporting System database.

Background: Anakinra is a recombinant interleukin-1 (IL-1) receptor antagonist used in systemic juvenile idiopathic arthritis (sJIA), refractory Kawasaki disease (KD) and cryopyrin-associated autoinflammatory syndrome (CAPS). Anakinra associated hepatotoxicity, while rare, has been described in several cases in daily practice. In this case series the authors describe three pediatric patients with this side effect in the setting of severe macrophage activation syndrome (MAS) in KD and sJIA.

Gianotti-Crosti syndrome (GCS) is a benign acral dermatitis commonly seen in children younger than five years of age with no gender predilection. Clinical features are often vague, including but not limited to fever, lymphadenopathy, and erythematous papular rash that commonly spares the trunk, palms, and soles of the feet. It is presumably underdiagnosed as most children presenting with a widespread papular rash are diagnosed with non-specific viral exanthem.
