In addition to radiography, we use computed tomography (CT) and arthroscopy to facilitate diagnosis of elbow dysplasia. CT can be performed under sedation or general anaesthesia . It is a very sensitive method for the diagnosis of stress fracturing of the coronoid process of the ulna and for the assessment of elbow incongruity and the bone underneath the cartilage. CT gives us very useful information for planning the best treatment of elbow dysplasia in your dog. We offer CT to most cases when elbow dysplasia is suspected. The entire study can be completed in minutes and gives us a three-dimensional picture of the disease process.

Fat gain may also be linked to insulin resistance. Insulin resistance can cause glucose intolerance, which has been associated with fat gain, increased triglycerides, and the development of diabetes. Insulin is a hormone produced by the pancreas to control blood sugar-glucose. HIV medications may block or slow down the process by which insulin converts glucose to energy. In laboratory studies, Crixivan and higher doses of Norvir and Zerit have been shown to impair the action of insulin in fat and muscle cells. In this scenario the pancreas will tend to produce more and more insulin to compensate for the decrease in function. High insulin levels may be present for years before type 2 diabetes develops. A glucose tolerance test (GTT) may reveal that problem easily but it is hardly used in clinical practices. Additionally, some people may have a genetic predisposition to insulin resistance. A sedentary lifestyle and a diet rich in sugars and animal fats may also compound this problem. In any case, insulin resistance may just be a part of the mystery of lipohypertrophy. There is no agreement among researchers whether or not monitoring insulin levels in HIV-positive people is justifiable or dependable as a tool to assess insulin resistance and fat gain.

However, a role for T cells cannot be dismissed because RTX may affect T-cell function. RTX has been effective in the treatment of rheumatoid arthritis, a classic T-cell-mediated disease. In patients with SLE, treatment with RTX results in a decrease in activated T cells [ 31 ], although the effect may be disease specific since no such changes were documented in patients with membranous nephropathy treated with RTX [ 32 ]. Furthermore, a small population of T cells do express CD20 [ 33 ]. Alterations in the nuclear factor kappa B (NF-kB) pathway of both CD4 T cells and non-CD4 mononuclear cells may be involved in the development of MCD [ 34 ]. RTX inhibits the constitutive NF-kB signaling pathway in B-cell lines, and it is possible that inhibition of this pathway may be beneficial in NS. B cells also play an important role in induction of inflammatory cytokines, antigen presentation to T cells, dendritic cells, and macrophages, T-cell activation and generation of ectopic lymphogenesis [ 35 ], and RTX may directly or indirectly alter T-cell function in patients with MCD. In fact, as Shalhoub [ 27 ] pointed out, ‘It is conceivable that the feedback control system governing the activity of helper and suppressor T cells depends to some extent on the concentration of specific immunoglobulin whose synthesis is affected by these cells. Consequently, if abnormalities of Ig synthesis can be demonstrated in lipoid nephrosis, the primary disturbance may involve B-cell dysfunction.’

Recently, a specific peptide inhibitor for ATGL was isolated from white blood cells, specifically mononuclear cells. This peptide was originally identifed as being involved in the regulation of the G 0 to G 1 transition of the cell cycle . This peptide was, therefore, called G0G1 switch protein 2 (G0S2). The protein is found in numerous tissues, with highest concentrations in adipose tissue and liver. In adipose tissue G0S2 expression is very low during fasting but increases after feeding. Conversely, fasting or PPARα-agonists increase hepatic G0S2 expression. The protein has been shown to localize to LDs, cytoplasm, ER, and mitochondria. These different subcellular localizations likely relate to multiple functions for G0S2 in regulating lipolysis, the cell cycle , and, possibly, apoptosis via its ability to interact with the mitochondrial antiapoptotic factor Bcl-2. With respect to ATGL regulation, the binding of the enzyme to LDs and subsequent is dependent on a physical interaction between the N-terminal region of G0S2 and the patatin domain of ATGL.
