together with怎么理解?

All transplant patients require regular lifelong clinic follow- up to monitor renal function and immunosuppression. Common immunosuppressive regimens combine prednisolone with ciclosporin or tacrolimus, together with azathioprine or mycophenolate mofetil. Treatment is associated with an increased incidence of infection, particularly opportunistic infections such as cytomegalovirus and Pneumocystis jirovecii. There is also an increased risk of malignancy, especially of the skin. Lymphomas are rare, but may occur early, and are often related to infection with herpes viruses, especially Epstein- Barr virus.

所有移植患者都需要定期终生门诊随访，以监测肾功能和终身免疫抑制治疗。常用的免疫抑制方案是泼尼松龙联合环孢菌素或他克莫司、加上硫唑嘌呤或霉酚酸酯。免疫抑制治疗使感染的发生几率增加，尤其是机会致病菌感染，如巨细胞病毒和卡氏肺孢子菌。恶性肿瘤尤其是皮肤恶性肿瘤的风险升高。淋巴瘤罕见但发生早，常与疱疹病毒尤其是EB 病毒的感染有关。

together with怎么理解?是“加上”还是就等于“or”？谢谢
