Steroid resistant acute cellular rejection

Up to 25% of patients with TB of the lymph nodes (TB lymphadenitis) will get worse on treatment before they get better and this usually happens in the first few months of treatment. [ citation needed ] A few weeks after starting treatment, lymph nodes often start to enlarge, and previously solid lymph nodes may soften and develop into tuberculous cervical lymphadenitis . This should not be interpreted as failure of therapy and is a common reason for patients (and their physicians) to panic unnecessarily. With patience, two to three months into treatment the lymph nodes start to shrink again and re-aspiration or re-biopsy of the lymph nodes is unnecessary: if repeat microbiological studies are ordered, they will show the continued presence of viable bacteria with the same sensitivity pattern, which further adds to the confusion: physicians inexperienced in the treatment of TB will then often add second-line drugs in the belief that the treatment is not working. In these situations, all that is required is re-assurance. Steroids may be useful in resolving the swelling, especially if it is painful, but they are unnecessary. Additional antibiotics are unnecessary and the treatment regimen does not need to be lengthened. [ citation needed ]

Prior to the FK506 era, OKT3 was primarily used for treatment of steroid-resistant rejection. Initially FK506 has been used as a last treatment of refractory acute or chronic rejection. We provide strong evidence that the use of FK506 is more successful if rescue therapy is performed early instead of using it as the last resort. Between September 1988 and March 1995 a total of 600 liver transplantations were performed in 550 patients. Of these 550 patients, 426 received primarily cyclosporine A (CsA)-based immunosuppression. Of the 426 CsA patients, 70 (%) required either FK506 (%), or OKT3 rescue therapy (%), or a combination of the two drugs (%). The latter group of patients received first OKT3 and then FK506 rescue when OKT3 therapy failed. Treatment was initiated simultaneously (within 1 week) in 11 patients, and 4 patients received FK506 rescue later during the course of rejection. The highest success rates (%) were observed in patients given FK506 rescue therapy. Retransplantation was necessary more often in patients receiving OKT3 than in those with FK506 rescue therapy (% versus %, respectively). Retransplantation and death due to chronic rejection increased with the need for additional FK506 rescue therapy after OKT3 failure. This increase was most pronounced in patients receiving FK506 during the late course of rejection, reaching a failure rate of % (50. 0% of deaths were due to chronic rejection). The lowest incidence of cytomegalovirus infection and of infectious, neurologic, and renal complications was observed in the FK506 rescue group. We conclude that early FK506 rescue therapy may be the treatment of choice for acute steroid-resistant rejection.
