Many of such patients may not show any clinically apparent renal disease keftab 250 mg with mastercard infection streaking, but when subjected to kidney biopsy glomerular lesions will be detected purchase keftab 250 mg online antibiotic resistance why does it happen. Clinical presentation of lupus nephritis patient may vary from asymptomatic urine abnormality to rapidly progressive glomerulonephritis. Furthermore, some patients show manifestations of tubulointerstitial nephritis (e. Treatment: There is no standard regimen for the treatment of lupus nephritis patient. The available treatment protocols include: (1) Prednisolone, oral, 1mg/kg/d, (2) 3-5 days pulses of methyl prednisolone 500-1000 mg each, (3) Cytoxan (cyclophosphamide) 2-3 mg/kg orally/d (4) cytoxan 0. Generally, the target of treatment is to induce remission, then to maintain it by small doses of either one drug (Prednisolone) or combined (e. The more active the disease, the more aggressive the treatment will be and vice versa. The classic type of polyarteritis nodosa may present with ischaemic renal changes, hypertension, immobilization with renal infarctions or haemorrhage related to the kidney (haematuria, peri-renal hematoma resulting from rupture of aneurysm). Treatment: Patients with active urine sediment (proteinuria, haematuria, casts), renal impairment and documented lesions in renal biopsy should be treated by immunosuppressive drugs to achieve remission. The dose and whether prednisolone alone or combined drug regimen, depend on disease activity and initial reponse to treatment. Cyclosporin A 5mg/kg/d can be used when these drugs are toxic or have no satisfactory response. Renal involvement is documented in 10-30% of the cases, but in some series, it reaches up to 90% of the cases. The primary abnormality is most probably defective handling of mucosally presented antigen. Light microscopy usually shows changes variable from minimal abnormalities, mesangial proliferation, focal mesangial proliferation with crescent formation to membranoproliferative glomerulonephritis. Immunofluorescent microscopy will show predominant IgA deposits which are mainly mesangial, and this is usually accompanied with C3, IgG and to a lesser extent IgM. Clinical features: 1- The disease usually occurs in winter, following upper respiratory infection or following exposure to allergen. Gastrointestinal manifestations including abdominal pain, bloody diarrhea and or melena.

Selection of a specific antipsychotic agent for therapeu- tic use is often based on its associated adverse effects rather than therapeutic efficacy buy cheap keftab 375 mg on line cowan 1999 antimicrobial. They are less likely to occur with low-potency conventional antipsychotic drugs such as thioridazine cheap 500 mg keftab visa virus alive, which have lower affinity for dopamine D2-receptors than high-potency drugs. With the exception of risperidone, they are also unlikely to occur with atypical antipsychotic drugs such as clozapine and olanzapine. Extrapyramidal effects are also less likely to occur with those conventional agents that also have sub- stantial antagonist activity at cholinoceptors in the basal ganglia.

Tardive dyskinesia (1) Tardive dyskinesia is much more likely with conventional antipsychotic agents than atypical agents. Neuroleptic malignant syndrome (1) Neuroleptic malignant syndrome is most likely in patients sensitive to the extrapyrami- dal effects of the conventional high-potency antipsychotic agents. Sedation (see Tables 5-3 and 5-4) (1) The sedation effects, more likely with low-potency antipsychotic agents and with the atypical agents, are due to a central histamine H1-receptor blockade. This effect is likely with antipsychotic agents with pronounced antimuscarinic activity. Seizures (1) Seizures are especially more common with chlorpromazine, clozapine, and olanzapine. Muscarinic cholinoceptor blockade (1) Blockade of muscarinic cholinoceptors, more common with conventional low-potency antipsychotic agents and with the atypical agent clozapine, produces an atropine-like effect, resulting in dry mouth and blurred vision. Endocrine and metabolic disturbances, likely with most conventional antipsychotic agents and the atypical agent risperidone, are due to dopamine (D2)-receptor antagonist activity in the pi- tuitary, resulting in hyperprolactinemia (see Table 5-4). In women, these disturbances include spontaneous or induced galactorrhea, loss of libido, and delayed ovulation and menstruation or amenorrhea. Weight gain, which is likely with most conventional antipsychotic agents and the atypical antipsychotic agents, clozapine and olanzapine, may be due in part to histamine H1-recep- tor antagonist activity (see Table 5-4).
