RESUMO
Infection and rejection outcomes were retrospectively analyzed in patients following liver transplant and separately following heart transplant with patients being stratified by their severity of immediate postoperative insulin resistance as measured by the peak insulin drip rate that was required to reduce glucose levels. For each group, these peak insulin drip rates were divided into quartiles (Q). In liver transplant patients (n = 207), those in Q4 (highest infusion rate) had significantly fewer infections up to 6 months post-transplant (42.3% vs. 60.0%, p = .036) and borderline fewer rejection episodes (25.0% vs. 40.0%, p = .066) compared to Q1-Q3 patients. To confirm these unexpected results, a subsequent similar analysis in heart transplant (n = 188) patients again showed that Q4 patients had significantly fewer infections up to 6 months (19.1% vs. 53.9%, p < .0001) compared to Q1-Q3 patients. Logistic regression in a subset of 103 cardiac transplant patients showed that the maximum glucose during surgery, prior MI, and hypertension were associated with severe insulin resistance (SIR) status, while the presence of pre-existing diabetes and BMI were not. We hypothesize that patients are who are able to mount a more robust counter-regulatory response that causes the insulin resistance may be healthier and thus able to mount a better response to infections.

Describimos las características clínicas y demográficas en pacientes adultos con espondilitis tuberculosa así como un análisis exploratorio que buscó establecer características que contribuyeron al desarrollo de esta enfermedad, en un hospital de tercer nivel de Lima. Realizamos un estudio tipo serie de casos y describimos 33 casos recolectados entre 1999-2009. 18 pacientes (55 por ciento) fueron varones, la media de edad fue 31 años (IQ 23 a 51 años) y un tiempo de enfermedad de 3 meses (IQ 1 a 8 meses). El principal síntoma fue lumbalgia en 28 (85 por ciento). Los segmentos más comprometidos fueron el torácico en 28 (60 por ciento) casos y lumbar en 13 (28 por ciento). Tuberculosis pulmonar se encontró en 14 (42 por ciento) casos. Veinticuatro (73 por ciento) recibieron esquema I. La duración de tratamiento fue 10,5 ± 4,2 meses . Las características clínicas, diagnósticas fueron similares a series nacionales previas e internacionales.
We describe the demographic and clinical characteristics of adult patients with tuberculous spondylitis as well as an exploratory analysis that seeked to establish patient characteristics that contributed to the development of this disorder at a reference hospital in Lima. This is a case-series descriptive study where data collection from 33 medical records of patients from 1999 to 2009 was done. Eighteen (55 percent) were male. Median age was 31 years (IQR 23 to 51 years). Median time of symptoms was 3 months (IQR 1 to 8 months). The most frequent symptom was back pain in 28 (85 percent). The most frequently affected areas were the thoracic spine involved in 28 (60 percent) cases and lumbar spine in 13 (28 percent). Pulmonary tuberculosis was present in fourteen (42 percent) cases. Twenty four (73 percent) patients received first line treatment. Treatment duration was 10.5 ± 4.2 months. Clinical and diagnostic characteristics were similar to previous Peruvian case reports and current literature.
