The treatment was considered successful if the participant maintained low-levels (less than 50 copies/mL) of HIV RNA in their blood for at least 48 weeks. In these studies, 91% of subjects with HIV-1 who took the dolutegravir/lamivudine combination no longer had detectable levels of HIV (i.e. they had fewer than 50 copies per ml) after 48 weeks compared with 93% of those who were taking the triple combination. In neither study was there a case of resistance to treatment after 48 weeks. References

In Blum & Ritters study in West Germany (1990), they found that 27% of their population had only minor issues, 72% had a palpable mass at the site, and 23% reported pain and other signs of inflammation such as hyperthermia, pulsation, and cystic, pustular, or papular lesions. Size of masses were an average of 2 cm in diameter ranging up to 4 cm, some being associated with purulent drainage, continuous discharge, and crusting. Dystrophic calcinosis cutis has also been reported. Other serious sequelae include sialolithiasis of the submandibular gland and adenolymphoma of the parotid gland.The histopathology of fiddlers neck frequently shows hyperkeratosis and acanthosis, along with plugging of follicles. Histiocytic infiltration with granulomas to foreign body and follicular cysts are also common. Foreign body granulomas are thought to derive from abrasion of the wooden surface of the chin rest and its absorption into the superficial dermis. The location and complex mechanism of causation for fiddlers neck give rise to a wider spectrum of skin changes when compared to contact dermatitis from more common irritants. Fiddlers neck can be differentiated from rosacea and sarcoid reaction with granulomas. Causes
The proximal causes of fiddlers neck are friction and pressure, but both repetitive shearing stress and occlusion with consequent trapping of sweat give rise to progressive damage. This damage along with poor hygiene predisposes the area to local infection, and such infection can progress to scarring and other long-term effects.
