The role of thyroid hormones in bipolar disorder continues to be investigated. Low levels of thyroxine T4 ; have been associated with more affective episodes during maintenance treatment with lithium60. Whether this mood instability is causally related to low free T4 levels and whether it can be attenuated with thyroxine replacement remain to be studied in a controlled setting. Open trials suggest efficacy for thyroxine as an augmenting agent in resistant bipolar depression and rapid cycling disorder61, 62.

Abstract: HIV therapies have been associated with alterations in fat metabolism and bone mineral density. This study examines the effects of HIV-protease inhibitors PIs ; on bone resorption, bone formation and adipocyte differentiation using ex vivo cultured osteoclasts, osteoblasts and adipocytes, respectively. Osteoclast activity, measured using a rat neonatal calvaria assay, increased in the presence of nelfinavir NFV; 47.2%; p 0.001 ; , indinavir IDV; 34.6%; p 0.001 ; , saquinavir SQV; 24.3%; p 0.001 ; or ritonavir RTV; 18%; p 0.01 ; . In contrast, lopinavir LPV ; and amprenavir APV ; did not increase osteoclast activity. In human mesenchymal stem cells hMSCs ; , the PIs LPV and NFV decreased osteoblast alkaline phosphatase ALP ; enzyme activity and gene expression significantly P 0.05 ; . LPV and NFV diminished calcium deposition P 0.05 ; , whereas the other PIs investigated did not. Adipogenesis of hMSCs was strongly inhibited by SQV and NFV 50%; p 0.001 ; and moderately inhibited by RTV and LPV 40%; p 0.01 ; . Expression of diacylglycerol transferase, a marker of adipocyte differentiation, decreased in hMSCs treated with NFV treatment. APV and IDV did not affect adipogenesis or lipolysis. These results suggest that bone and fat formation in hMSCs of bone marrow, may be coordinately down regulated by some, but not all PIs.

Incidences was 5%, 15%, and 45% for 900, 1050, and 1200 mg APV doses, respectively p 0.003 by posthoc comparison ; . The proportion of patients who discontinued APV due to the development of an adverse event was higher with increased APV dosing: 10%, and 40% for the 900, 1050, and 1200 mg groups, respectively p 0.022 by posthoc comparison ; . A relationship between indinavir IDV ; and toxicity has also been demonstrated. Burger4 evaluated 19 patients receiving IDV 800 mg every 8 hours with 8-hour pharmacokinetic curves at week 4 of therapy. The study defined nephrotoxicity as flank pain, hematuria, or an increase in serum creatinine of 25%. The concentrations of IDV were similar to previous studies and correlated with weight. Patients with elevated Cmax above 10 mg L ; and AUC above 30 mg L per h ; had greater incidence of nephrotoxicity, but there was no association between Cmin and nephrotoxicity. Although it is clear that low PI and NNRTI concentrations predict reduced virologic success and that elevated concentrations increase the likelihood of toxicity, there are many questions that need be addressed before therapeutic drug monitoring can be incorporated into clinical practice. Among the issues that need to be considered are: A. What are the clinical CD4, HIV RNA, AIDS history ; and genetic Pglycoprotein and cytochrome P450 alleles ; factors predictive of sub-optimal plasma concentrations? B. Which method should be used to measure the level? C. W h parameter should be measured- Cmin, Cmax, AUC and how should these parameters be evaluated i.e., single trough measure, sparse sample or full PK sampling ; ? D. What is the cut point for considering a PI or NNRTI level to be.

A typical CM-Sephadex chromatogram of the mung bean proteins is shown in Figure 1. As noticed, three protein peaks were obtained with the acetyltransferase activity present in peak II. Rechromatography of the concentrated protein solution from this peak on CM-Sephadex column resulted in the formation of two protein peaks as shown in Figure 2 with the acetyltransferase activity being present in 12-L peak II. A summary of the data on the partial purification of the enzyme is presented in Table I. A 313-fold purification of 0.8 the enzyme with 65% yield was obtained. Column chromatography on diethylaminoethyl cellulose, on Sephadex G-100, or adsorption chromatography on calcium phosphate gel did not result in any further purification of the enzyme. As seen in 1oo Table I, adjustment of pH to 4.9 did not result in an increase 60 80 70 specific activity compared to the protamine sulfate fraction.

Q. What is the interaction between Non-Steroidal Anti-Inflammatory Drugs NSAIDs ; and Angiotensin-Converting Enzyme inhibitors ACE inhibitors ; ? NSAIDs block the cyclooxygenase pathway and thereby inhibit formation of vasodilatory prostaglandins. The latter help to maintain renal blood flow in severe heart failure and other disease states when the kidneys are underperfused. NSAIDs therefore cause constriction at the afferent pre ; glomerular arteriole, and can precipitate renal failure in susceptible patients. They can also cause fluid and sodium retention which is undesirable in e.g. congestive heart failure chronic renal failure. ACE inhibitors, as vasodilators, cause dilation of the efferent post ; glomerular arteriole. This reduces the filtration pressure across the glomerulus and can cause a decline in renal function. At risk patients include those with congestive heart failure or renal artery stenosis who rely on Angiotensin-II mediated vasoconstriction to maintain renal perfusion. Therefore if an NSAID is prescribed with an ACE inhibitor there is the potential for additive adverse effects on renal function. Therefore the following need to be considered: a ; indication for ACE inhibitors e.g. hypertension or heart failure b ; choice of NSAID e.g. indometacin causes more sodium retention than other NSAIDs c ; whether PRN dose of NSAID or long term treatment d ; baseline renal function In summary clinicians should be wary of co-prescribing an ACE inhibitor with an NSAID in conditions of renal hypoperfusion e.g. elderly patients with congestive heart failure, liver cirrhosis, chronic renal failure etc ; . Urea, electrolytes and creatinine should be monitored and the necessity for an NSAID should be evaluated and isradipine.

The vitality can be considered to be a measure of the enzymatic fitness of a particular mutant in the presence of a given inhibitor. For example, the double resistant mutant in the B subtype V82T I84V has a reported vitality close to 10 for ritonavir and indinavir. Vitalities as high as 20 have been reported for the single mutants V82F and V82T in the presence of indinavir 5 ; . The vitality also can be used to compare the proteases from other subtypes in relation to the B subtype wild type ; . Fig. 3 shows the vitalities obtained for the A and C subtypes in the presence of indinavir, saquinavir, nelfinavir, and ritonavir for the two substrates considered in this study. Even though the experimental errors are amplified in the calculation of vitalities, the A and C proteases exhibit values higher than unity. In general, the vitalities for the A and C proteases are not as high as those reported for primary resistant muations and in some cases they are close to unity indicating a similar biochemical fitness. For the A subtype, vitalities as high as 5 were observed in the presence of indinavir and ritonavir and around 1.5 for nelfinavir and saquinavir. For the C subtype, on the other hand, vitalities around 810 were observed in the presence of indinavir and ritonavir and around 5 for nelfinavir and saquinavir and kaletra.
