This immune system improvement can trigger various immunological phenomena, entity called Immune Reconstitution Syndrome (IRS). Graves’ disease is a late Immune Reconstitution consequence. Patient: We report the case of a 48 years old man with HIV infection who developed Graves’ disease three years after he was on effective HAART because of the Immune Reconstitution Syndrome. At presentation he had a very low CD4 T-cell count (17 cells/μL). When he started HAART he presented a lipodystrophy syndrome. HAART was changed because of the persistent low CD4-T cells count (less than 100 cell/μL). Afterwards serum lipid levels began to decrease and that was the first manifestation of Graves’ disease, which was diagnosed when CD4 T-cells increased up to 343 cell/μL. Our patient developed Graves’ disease 36 months after initiating effective HAART with protease inhibitors which was coincident with viral suppression and a rise of CD4 T cells. Conclusion: The most immunosuppressed patients with a CD4 T cell count less than 100 cells/μL are at greatest risk for the development of Immune Reconstitution Syndrome after HAART initiation. We conclude that clinicians will have to consider the importance of the early diagnosis of thyroid disease to bring an adequate treatment.展开更多

It is characterized by anti-inflammatory cellular responses that allow embryonic implantation. The reversal of these changes during the postpartum period may result in overt clinical manifestations of otherwise quiescent or latent infections. We present an Acute Respiratory Distress Syndrome (ARDS) case after a caesarean section related to the Immune Reconstitution Inflammatory Syndrome (IRIS) in a Guinean black woman. The patient was treated with large doses of corticosteroids showing a great clinical and radiological improvement.展开更多

However, the numbers of subjects were small in previous Chinese studies. This study evaluated the efficacy and side effects of HAART in Chinese advanced AIDS patients.Methods One hundred and three antiretroviral drug naive AIDS patients were enrolled in this study and were divided into two groups by their baseline CD4^＋ count： 〈 100 cells/μl or ≥ 100 cells/μl. Clinical, virological and immunological outcomes were monitored at baseline and at 1, 3, 6, 9 and 12 months during the course of treatment with HAART.Results One patient died and another was lost from the follow-up. For the remaining 101 HIV/AIDS patients at the 12th month during the HAART, the plasma viral load （VL） was reduced to （3.2±0.7） lg copies/ml, the CD4^＋ count increased to （168 ±51） cells/μl [among which the naive phenotype （CD45RA^＋CD62L^＋） increased to （49 ±27） cells/μl and the memory phenotype （CD45RA^-） increased to （119 ±55） cells/μl], and the percentage of CD4^＋CD28^＋ cells increased. At the same time, there was a significant reduction of CD8^＋ T cell activation. In the 69 patients with the baseline CD4^＋ count 〈100 cells/μl, 37 had a VL 〈50 copies/ml; while in the 34 patients with the baseline CD4^＋ count ≥ 100 cells/μl, 25 had a VL 〈50 copies/ml, the difference between the two groups was statistically significant. The CD4^＋ T cell count showed a two-phase increase during HAART and a significant positive correlation was shown between the change of CD4^＋ count and plasma VL. Over 12 months of HAART, 10 patients had gastrointestinal side effects, 13 peripheral neuritis, 7 hepatic lesions, 8 hematological side effects, 8 skin rashes, 10 lipodystrophy and 1 renal calculus.Conclusions Immune reconstitution as well as the significantly improved clinical outcomes is observed in Chinese advanced AIDS patients after HAART. Side effects are common during HAART and require clinical attention.展开更多

Methods From October 2002 to March 2004, 20 cases of late stage Chinese AIDS patients were selected to participate in this opened and randomised study, we purposely chose those with CD4＋ T cell counts 〈 100/mm^3. All of them had one or two opportunistic infections and none had been treated with anti-HIV drugs. All patients were tested with CD4＋ （naive CD4＋ T cell defined by CD45RA＋ and CD62L＋, memory CD4＋ T cell defined by CD45RA-）, CD8＋ T cell, plasma HIV viral load, and clinical manifestations on before, during, and after HAART （5 different regimes） on 1, 3, 6, 9, and 12 months. Before HAART mean CD4＋ T cell counts were 32 ± 31 （range 2-91）/mm^3, and plasma HIV viral load were 5.07 ± 0.85（range 2.04-5.70） log copies/mL. In 1 month＇s time patients treated with HAAT had mean CD4＋ and CD8＋ T cell counts increasing rapidly. After 1 month the increasing speed turned to slow down, but HIV viral load decreased predominantly within the first 3 months. The major part of increasing CD4＋ T cells were memory CD4＋ T cells, as for naive CD4＋ T cells increasing low and slow. Clinical symptoms and signs improved, and opportunistic infections reduced. The quality of life will be far much better than before. Each patient was followed for 12 months, and had finished 12 months＇ HAAT. Conclusion This is the first report in China that late stage Chinese AIDS patients after HAART could have their immune reconstitution. The regular pattern is similar to what had been reported in Western countries and also in China. So it is worth to treat late stage Chinese AIDS patients with HAAT.展开更多

Its clinical symptoms lack specificity but can be evaluated using diagnostic imaging. High-resolution computed tomography(HRCT) is useful in evaluating the morphology and internal microstructure of lesions associated with the syndrome, as well as the relationship of the internal microstructure with the surrounding tissues. This paper summarizes the present state and progress of imaging research on IRIS caused by AIDS and complicated by tuberculosis.展开更多
