Guest guest Posted July 25, 2001 Report Share Posted July 25, 2001 Dear Forum members, The following is the protocol for HIV/AIDS mangement adopted by the Freedom Foundation. This is a very significant work as there is very limted work on issues related to developing a protocol for HIV Case management in India. The moderator would like to comment on the authors of this document. It will be appreciated if any of the readers could review this protocol. We will be glad to post the review article on the Forum. [Moderator] _________________________________________________ There are two components in any HIV / AIDS rehabilitation programme that are extremely critical. " ACCEPTANCE & FREEDOM " THE FREEDOM FOUNDATION'S PROTOCOL FOR CASE MANAGEMENT OF HIV/AIDS Tel : 0091 80 5449766 5440134, 5440135 , 5443101 website:www. thefreedomfoundation.org e-mail : freedom@... __________________________________________________ MEDICAL PROTOCOL FOR PLWHAs Someone once said that only the brave venture into palliative care and only the bravest venture into care for people living with HIV & AIDS. The treatment of any person infected with HIV is 3- dimensional. It focuses on the physical, psychological and the social aspects of the illness. Caring for people with HIV is a team effort. As care givers, we need to realize that there is no need for a specialized degree inorder to care for people living with HIV & AIDS (PLWHAs). The infections that are seen in HIV infected individuals are not peculiar or unheard of. What we need to know is that their health problems are complicated by the fact that they may have multiple infections and may require prolonged treatment. History : It was in 1981 in the U.S.A. that doctors began to notice an increase in the number of people being diagnosed with PCP- pneumocystis carnii pneumonia- which until then was quite rare. In the same year, there was an increase in the number of cases reprting with Kaposi's sarcoma. The intriguing factor was that these patients were all young men who had no previous history of illness. Another common factor was that they were homosexual men. Tests showed that these men were all immune-compromised. In 1983, researchers in France and almost simultaneously in the U.S. established the link between the immune-compromised states and a virus which was later called the Human Immune Deficiency Virus - HIV. It was in 1986 the first case of HIV was reported in India. It was found in a group of commercial sex workers in Chennai. Why do we need to be aware of HIV & AIDS? India today has the highest number of HIV +ve people. Statistics report that we have about 3.8 to 4 million HIV +ve people in the country today. What is even more alarming is that studies reveal that 2 new HIV infections are occurring every minute. With these kind of numbers, it is obvious that medical practitioners and health care workers ( HCWs) at some point in their careers are going to come across people infected with the virus. It is but natural that HCWs would be afraid of getting infected with HIV while caring for an infected individual. This fear can be averted by being well aware of the routes of transmission and the risk of infection involved. The need for a protocol- The Freedom Experience: So far, 90% of material available on HIV & AIDS is based on studies conducted in the West. We do know that the HIV strains in the West are different from those found in our population. The diseases seen and even the drug reactions vary between the west and in Asia. For eg: Hypersensitivity to Co-trimoxazole is more common in the Caucasians than among the Indians. The quality of nutrition, availability of drugs, etc. all play a role in HIV management. Hence, we felt the need to have guidelines for doctors and other care givers working with PLWHAs. In the Indian scenario, there are more OIs to contend with than there are in the West. The availability of drugs is also a cause for concern. Before we go onto medical management, it is important to familiarize ourselves with the other factors concerned with HI & AIDS. Transmission: 1. Blood transfusion: There is a 90% risk of infection through transfusion of HIV infected blood. This involves blood products like plasma, platelets, etc. 2. Mother to child transmission: There is a 25-30 % risk of transmission from an infected mother to her child. This transmission can occur during pregnancy or during delivery. The virus can also be transmitted to the child during lactation. 3. Through sexual intercourse: The risk of getting infected through unprotected sex with an infected partner is about 1%. This risk is especially high among homosexual men since anal penetration is involved and this means that there is a chance of sustaining mucosal injury. Amongst hetero-sexuals, the women is at more risk of infection that the man. This is because the vagina is in contact with the semen for a longer period of time. In addition, injury to the vaginal mucosa is also a possibility during intercourse. 4. Risk to health care workers: There is no risk of getting infected by touching an HIV infected individual. There is no risk of infection if infected blood is to come in contact with intact skin. The risk of getting infected due to a needle stick injury is between 0.3 - 1 %. This risk can be minimized further is we follow a few simple steps that safe guard us. Any care giver for people with HIV or Hepatitis B needs to be aware of the Universal precautions: These are steps that have to be followed by the health care workers ( HCW) with every single patient. · Washing of hands before and after checking up a patient. Just soap and water is enough. This is a very basic precaution and yet we seem to forget it. · While dealing with any person with open wounds or discharging wounds, always wear gloves. * While performing any invasive procedure like incision and drainage, pleural tap, etc, the doctor and the assistant should be protected with gloves, a mask and goggles. In addition the doctor needs to be protected with a disposable apron. · all infected material like blood, vomitus, etc should be disinfected with bleaching powder or 5% hypochlorite solution. · all needles and syringes, infected dressing material should be disinfected with hypochlorite solution before being disposed. · all suction tubes, endo-tracheal tubes etc. need to be disinfected with glutaraldehyde solution before re-using. * always make sure to have on foot wear. Disposal of medical waste: All infected material like syringes, dressing material, or other material infected with blood or other body fluids first needs to be disinfected in hypochlorite solution. Only after disinfection for about 5 hours, can all the medical waste be disposed. This then needs to be incinerated. Sanitary napkins need to be burned. The care givers team at a center for HIV & AIDS: 1. The doctor 2. The counselor 3. Nurses. ( The ideal ratio would be 1 nurse to 5-6 beds.) 4. Social worker ( for house visits & for awareness programs) The aims of treatment in PLWHAs: The treatment given is to ensure that the person has a QOL (quality of life) that is acceptable to him/her as is the right of any person. 1. To make the person aware of his HIV status and counsel him about stopping risk Behaviour. 2. To provide treatment for the opportunistic infections. 3. To provide symptom control and reduce any distress in the patient. Infact, in people with HIV & AIDS, like in those with cancer, palliative care begins from the time the person is found +ve. 3. Social acceptance and family acceptance of the person. STEPS INVOLVED IN ASSESSING A PATIENT: Counseling is part of the work of any doctor working with HIV +ve people and he needs to be sensitive to the issues affecting HIV +ve people. a. PRE- TEST COUNSELLING: ( sample of pre-test form enclosed) 1.Information about HIV to be given to the person. The modes of transmission, Issues of confidentiality, etc. have to be discussed. The effects of HIV,any questions the patients may have regarding his/her health etc, need to be answered. 2.Testing is done only after the patient consents to test his blood and he signs the pre-test form. b. POST - TEST Counselling: ( sample of post-test counseling forms enclosed) Has to be done regardless of the outcome of the HIV test. Disclosure of the status, followed by reassurance of confidentiality, care and support. 1. HIV -ve: - information and reassert the importance of stopping risk behaviour. - Condom demonstration. - Counselling regarding admission to a de-addiction center, if required. 2. HIV +ve: - allow time for the result to be understood, once again explain the implications of HIV. - give patient time to realize the emotional impact - observe for feelings of shock, denial, anger, etc. - assess and reassure - assess whether the patient requires inpatient or out patient treatment. MAJOR SIGNS OF AIDS defining illness: a. Fever : not responding to treatment * 1 month b. Loss of weight: more than 10 % loss of body weight in 1 month c. Diarrhoea : not responding to medication for 1 month. MINOR SIGNS OF AIDS defining illness: a. T.B, other lower respiratory infections, PCP b. Herpes Zoster especially involving more than 1 dermatome, c. Fungal infections of the skin, oral candidiasis d. T.B. meningitis, cryptococcal meningitis, toxoplasmosis. ** Toxoplasmosis if diagnosed in any person is an indication for testing for HIV. ** If a person has 2 major signs and one minor sign, or has all 3 major signs, the person needs to be tested for HIV. TESTING: The present reliable tests available in India are anti-body based tests. - ELISA - Rapid spot test - Western Blot There are other tests like PCR & viral culture which test for the virus itself. The problem with the viral tests are that they are very costly and sometimes are that the reliability of the tests are not assured. Time for testing: - The anti-body tests are reliable only when the person has passed the window period. The window period is time from the time of HIV infection to the time the anti-bodies to the virus shows up in blood tests. This could vary from 3 months to 6 months. The window period is important since during this period the persons test shows HIV -ve and during this time he/ she may continue risk behaviour or donate blood and thus infect another person. Criteria for admission: If a person has come in a with moderate to severe physical symptoms, or he requires adequate counseling regarding his illness he needs to undergo admission. The admission could be either a short stay of 1 week to 10 days or it could depend on the prognosis of the person. Sometimes however, a patient might require a longer duration of stay incase of abandonment, till we either work through with the family or we can find suitable accommodation. Testing for children: The anti body based tests are to be done only after the child has crossed 18 months. It takes about 18 months for the viral antibodies to be eliminated from the infant's system. On the other hand the PCR can be done after 72 hours of birth. The PCR tests for the viral antigens itself. A detailed clinical history needs to be taken prior to starting any form of treatment. The clinician needs to check for opportunistic infections and this is why the various tests mentioned below are important. Tests to be done at the time of patient assessment: 1. HIV spot for confirmation 2. ELISA at a governmental nodal centre 3. VDRL 4. HBs ag 5. Chest X-ray 6. Sputum AFB & Grams stain ** all care givers need to be immunized against hepatitis B. Treatment of VDRL reactive cases: * Drug of choice : Penidure 24 lakh units im to be given after test dose. To be given once a week for 3 weeks. In patients that can't tolerate a large dose, 12 lakh units once a week for 6 weeks can be given after test dose. · In case of people who are sensitive to penicillin or in pregnancy, the person needs to get Erythromycin stearate 500mg qid 2weeks. · Counselling needs to be done for the partner as well. Opportunistic Infection management: ** In children, the dosage needs to be adjusted as per the body weight. ** Drugs contra-indicated in paediatric age group are to be taken note of. ( Streptomycin, tetracyclines etc are not to be used in children.) ** All children need to be treated in co-ordination with an experienced paediatrician. 1. Tuberculosis: About 90% of persons with HIV come in after they have been diagnosed with tuberculosis. T.B. has gained notoriety due to the fact that there is an increase in the number of sputum +ve cases and so also in the numbers developing resistance to first line of treatment. It is advisable to have a tie up with the district T.B. center and also the DOTS centers. First it is important to assess whether the person has pulmonary Kochs, whether he has AFB in the sputum, T.B. meningitis or extra pulmonary T.B. For sputum +ve cases, the person needs to be on 4 drugs. If possible, it is necessary to try and register with the DOTS center. It is important to supervise the treatment. It is for the doctor to decide whether the patient will abide with the DOTS 3 day regime or the daily regime. DOTS: Drugs to be given only on Monday, Wednesday and Friday in the morning. The intensive phase is for 2 months. The drugs given are: Rifampicin 450 mg, INH 600 mg, Ethambutol 1200 mg, Pyrazinamide 1500 mg, Pyridoxine 40 mg The continuation phase is for given 4 months. The drugs given are: Rifampicin 450 mg , INH 600 mg & Pyridoxine 40 mg. Daily regime: The treatment is to be given every day without any breaks. The intensive phase is INH 300 mg, R-cin 450 mg, ETM 800mg, PZA 1500 mg, Pyridoxine 40 mg. The continuation phase is INH 300 mg , R-cin 450 mg, pyridoxine 40 mg. · During the intensive phase, sputum examination is to be done once a month to see whether the patient is responding to the treatment. · If at the end of 2 months, the person is still sputum +ve for AFB, they need to be given Streptomycin 75 mg along with the 4 drugs. This needs to be given for another 2 months and then the person goes through the continuation phase with 2 drugs. · If despite the streptomycin, after one month, the persons sputum still shows the same sputum AFB count or the AFB count has increased, then a culture sensitivity needs to be done to the first line drugs. The reports for c/s take about 3 months. In the meantime, if the person can afford it he may need to be started on Ciprofloxacin 500mg bd or Ofloxacin 200mg bd. · All sputum +ve cases need to be isolated as they put other patients also at risk of getting T.B. · A decrease in the sputum AFB count and gain in weight is an indicator of good response to the treatment. Pulmonary T.B. If the person is not sputum +ve but has pulmonary T.B., then he needs to be put on 3 drugs during the intensive phase. The drugs are INH, R-cin & ETM. The dosage are the same as the ones mentioned above. During the continuation phase, 2 drugs are given ie: INH, R-cin and pyridoxine. The dosages remain the same. T.B. meningitis: The treatment is to be given every day. 4 drugs are given. INH 300 mg, R-cin 450 mg, ETM 800 mg, PZA 1500 mg, Pyridoxine 40 mg. If the patient shows severe meningeal irritation with increase in intra cranial tension then the person needs to receive mannitol once or twice a day till there is an improvement in his condition. The continuation phase may be maintained upto 2 years to prevent relapse. Disseminated T.B. Is treated with 5 drugs ( INH, R-cin, ETM, PZA & Streptomycin) For 2 months and 2 drugs ( INH, R-cin ) for 4 months. Whether to follow the DOTS regime or the daily regime is dependent on the doctor's assessment of the patient. Hyper- sensitivity reactions to T.B. medication: 1. INH : can cause peripheral neuropathy. This is usually managed by increasing the dosage of pyridoxine. 2. R-cin: is hepato toxic. It can cause jaundice. In such a case, the drugs need to be stopped till the jaundice is controlled and then re-introduced one by one. 3. ETM: causes optic neuropathy. 4. PZA: can cause joint pains. 5. Streptomycin: causes oto- toxicity leading to giddiness, and disturbance in gait. In this case, it is advisable to stop the Streptomycin injections. Sometimes, there may be hyper-sensitivity skin reactions. The medicines need to be stopped. When the rashes disappear, then the drugs need to be re-introduced one by one. At Freedom Foundation, we have seen hypersensitivity reactions similar to 's sydrome. In such severe reactions, steroids and topical soothening agents need to be given. Atypical T.B.: It is very common in HIV +ve people. The clinical signs are more or less the same. A definitive diagnosis is made usually by doing a biopsy in cases of lymphadenitis. In cases of lung infection, an X-ray and a sputum examination will be necessary. In cases of atypical T.B. the drugs of choice are ETM 800mg, R-cin 450mg , Sparfloxacin 200 mg bd & Clarithromycin 250 mg bd. Multi-drug resistant T.B. Is a concern in HIV +ve people. Especially, since there would be previous history of defaulting with their T.B. medication. In such cases the 2nd line of T.B. medication need to be given. The treatment is prolonged and may be continued for a year and sometimes even more. 2. Oro - oesophageal candidiasis: It depends on the severity of the candidiasis. If the candidiasis is very mild, then usually they respond to Clotrimazole oral application. In mild to moderate infection, they require 150 - 200 mg Fluconazole once a day for 2 weeks. In case of very severe infection where the person is unable to swallow, the person needs to be put on i.v preparation of Fluconazole, 200mg twice daily. Once the person begins to improve, then he can be put on to 200mg orally for 2 weeks. Once the infection subsides, the person needs to continue oral application of Clotrimazole. In case of resistance to fluconazole , the person needs to be started on Itraconazole 200mg twice daily. Itraconazole is to be taken with food. 3. PCP: The diagnosis is usually based on clinical findings. High fever & dyspnoea are visible signs. There will be a drop in the oxygen saturation. The treatment is usually Trimethoprim 160mg + Sulphamethoxazole 800 mg ( co-trimoxazole) twice daily. If it does not respond, then Dapsone 100mg once a day needs to added to the regime. Incase it does not respond to that also, Clindamycin 600mg bd is proven to be very effective with primaquine 30 mg. The drug of choice if available is pentamidine. 4. Herpez - Zoster: Herpes in people with HIV usually occurs in more than one dermatome. The treatment of choice is Acyclovir 800 mg 5 times daily for 2 weeks. Along with this, if the patient has pain, then NSAIDs need to be given. If the herpetic neuralgia persists, imipramine or amitryptilline and in some cases carbamazepine may be tried. Topical acyclovir ointment also gives the person relief. 5. Cryptococcal meningitis: The treatment of choice is Amphotericin B. 0.7 mg/ kg to start with and gradually increase to 1 g / day, till the LP is negative for cryptococci. However, the Indian population needs upto 0.1-0.2 mg/kg body weight. Initially, we start with 0.1mg/kg and slowly increase it to 0.2mg/kg. It is given as a slow infusion in 5% Dextrose. It needs to be titrated and regular electrolyte monitoring needs to be done. So, usually this is done in a hospital set up. We have found that Amphotericin (in the doses we have mentioned) when given for 2 weeks along with Fluconazole 200mg bd is as effective as giving higher doses of Amphoterecin and the same time,we can minimize the adverse effects of Amphoterecin. Continuation therapy with Fluconazole 200mg bd is given till there is a sustained improvement in the patients condition. This takes about 6 weeks. Maintainance dose with fluconazole 200mg od is given. or Fluconazole 400 mg twice daily for 8 weeks. Then maintainance, 200mg od is continued. 6. Lower Respiratory Infection: If there is any expectoration, we can do a Gram stain and start the person on anti-biotic treatment as per the Gram stain result. Lower respiratory infection is to be, managed as with other people. 7. Urinary tract infection: Rule out sexually transmitted diseases. Check for ulcers, discharge and lymph node involvement which is suggestive of STDs. Incase STDs are ruled out, we can start them on urinary anti-biotics. Norflox, Co-trimoxazole, or Ciprofloxacin can be used as per the recommended dosages. In case there is no response to the usual anti-biotics, we can do a culture sensitivity test and proceed as per the sensitivity report. 8. Diarrhoea: We need to know that the HIV may itself cause viral enteritis. Find out the nature of the diarrhoea. If it is mucous stained and foul smelling it is indicative of amoebiasis. In this case, metrogyl 400 mg tid is usually the drug of choice, to be given for 5 days. Other wise, tinidazole 400 mg bd, or secnidazole forte 2 grams stat to be given. If despite this the diarrhoea persists, start on furazolidine 200 mg tid for 5 days. The furazolidine is to be given along with metrogyl. In case of watery diarrhoea, shigella dysentery is suspected. For this, Co-trimoxazole in double strength is the drug of choice. Nalidixic acid 600mg tid for 5 days is also used. Usually this is given along with metrogyl in the usual dosage is given. 9. Fever: All the causes for fever need to be ruled out. Typhoid, malaria, T.B., LRI, UTI all need to be ruled out. Typhoid: Tab Chloremphenicol 400 mg qid for two weeks is the drug of choice. Then the dosage is halved for another week. In case the person does not respond, then other lines of drugs like Ciprofloxacin 500 mg bd / Inj Gentamycin 80 mg bd/ one of the cephalosporins need to be given in combination with chloremphenicol. We have come across multi-drug resistant strains of typhoid as well. In such cases, a combination of 3 drugs has proved effective. Malaria: The treatment is Chloroquin 600mg initially, followed by 300mg after 6 hours and then 300mg once a day for 3 days. In cases of recurrent malarial attacks, 2 tablets with a combination of Pyrimetahmine 25mg + Sulphamethopyrazine 500mg needs to be given as a single dose. The management of T.B. LRI & UTI have been mentioned. 10. Toxoplasmosis: The drug of choice is pyrimethamine. 200 mg stat followed by 50- 100 mg /day. Folinic acid 10 mg /day is to be given along with this. Sulfadiazine 4- 8g / day or Clindamycin 900 mg /day, may be added to the regime if there is no response. 11. Syndromic management of STDs: Sometimes, identifying the exact organism of an STD is difficult, especially in cases where they are HIV +ve. Hence an approach where all the expected STDs are taken care of, is done. Partner treatment is also required. a) Urethral discharge: i. Tab Ciprofloxacin 500 mg single dose along with Doxycycline 100 mg bd for 1 week. ii. Inj Ceftriaxone 250 mg sd. Vaginal discharge: i. Tab Ciprofloxacin 500 mg single dose along with Doxy 100mg bd and Metrogyl 400 mg bd for 1 week may be accompanied with clotrimazole ointment or vaginal tabs. Or In pregnancy ii. Inj Ceftriaxone 250 mg single dose Or iii. Tab Erythromycin 500mg qid for 1 week c) Inguinal swelling: Doxycycline 100mg bd for 15 days. d) Lower abdomen pain: Doxycycline 100 mg for 15 days and Metrogyl 400mg for 1wk e) Genital ulcers: Inj Benzathine penicillin 24 lakh units im once a week for 3 weeks after test dose. f) Herpes: Tab acycovir 200 mg 5 times a day for 1 week. g) Scrotal swelling: Tab. Doxycycline 100 mg bd for 15 days. At a care & support unit for HIV: ** Every month deworming has to be done for adults with 400mg Albendazole. ** Every month blanket treatment for scabies needs to be done. Bezyl benzoate application is very effective. ** Cotrimoxazole double strength once a day is given as a prophylaxis for many infections such as toxoplasmosis, diarrhoea, PCP,etc. PAIN MANAGEMENT IN PLWHAs: Pain in people with HIV and AIDS is unfortunately not recognized. Unlike people with cancer, where pain is given utmost importance, pain in HIV is not usually considered. Added to this is the fact that most people infected with HIV usually have the problem of alcohol addiction/ drug addiction. Hence, the issue of dependence is highlighted more than they fact that these people also have a right to a pain free life. We need to realize that a person is in pain when he says so. As doctors, our part is to find the cause of the pain and ease his pain. As with any care and support facility, we need to remember that they have a right to a quality of life that they find acceptable. For this, the WHO ladder of pain management needs to be followed. As per the ladder, pain management starts with NSAIDs starting with the minimum dosage and then progress to the maximum dosage. Sometimes, NSAIDs along with adjuvants like anxiolytics, anti-depressants or sedatives are required. The next step is to progress to weak opiates. Only then should we progress to strong opiates. The list of drugs mentioned below are those commonly available in India. * Before venturing onto pain management, it is important to know the maximum effective dosage of the drugs. I . The NSAIDs commonly used are : i. Paracetamol ii. Nimesulide iii. Diclofenac iv. Bruphen v. Piroxicam vi. Ketorolac ( a very potent analgesic, needs to be used with discretion, preferable to start with the common analgesics first, before trying ketorolac) II. The weak opioids are: i. Propoxyphene III. The moderately strong opioids are : i. Tramadol IV. The strong opioids are Morphine and Buprenorphine. Today there are more potent analgesics like meloxicam and pyricoxib available. The cost factor usually is a limitation. ** Morphine is still not available for use in homes for PLWHAs. There are a lot of hurdles involved in obtaining liscence for morphine usage. Buprenorphine, however is available to registered institutions. ** Pain management should be given round the clock. Ie: bd or tid dosage as per the bio-availability and efficacy of the drug. ** Wherever possible, it is important to try and treat the cause, as in T.B., candidiasis,etc. ** Sometimes, where there is no specific treatment, then the pain alone needs to be managed. ** Don't jump from one NSAID to another. NSAIDs in combination can be used. Eg Nimesulide + Paracetamol. But refrain from using one NSAID then trying another and then another. If an NSAID or a combination of NSAID in optimal dose doesn't provide relief, then it is unlikely that another one will do the trick. ** A weak opioid needs to be used with a non-opioid analgesic, not separately. ** In case of AIDS, where the person is obviously in his last, we need to respect the person's wishes to have a pain free end. Anti-retro viral treatment At FF, we have noticed the enormous impact that Anti-retro-viral (ART) has on improving the health and therefore the QOL of HIV +ve people. Prior to starting the treatment, the doctor needs to be very aware of the dosage, the expected side effects, the costs and the availability of the drugs. The doctor needs to be aware that under dosing can lead to resistance in the virus. Also, the doctors need to be aware that these drugs are to be given life long and is not a short course. Anti-retro viral treatment in the Indian scenario: The need for assessment of the patient and counselling Most people can't afford anti-retro viral treatment in India. Any person opting for ART therefore needs ample counseling prior to starting medication. The counseling in this case needs to emphasize the cost factor, the need to take the drugs life long, the side effects, and the fact that the drugs are not a cure. The possibility of the drugs proving ineffective after 2-3 years need to be explained. The ability of the virus to turn resistant to the drugs has to be reinforced. Only with full consent of the patient can the drugs be started. ART makes economic sense: Once a person is started on ART, it is but obvious that his CD-4 count is going to increase. A good CD-4 count means that his immune system is going to improve and be able to defend himself against OIs. This is a two-pronged weapon where the cost of OI management can be saved and at the same time, the QOL of the person is improved. As the persons health improves, he is able to work and thus earn a living to support himself and his family. Good health also means lesser hospitalization. In our set up,we have seen that ART not only boosts the health of the person, but also the morale of the person. Doctor Patient relationship: This can-not be over emphasized. The patient needs to be able to confide and trust the doctor with his/her problems. There are a lot of side effects to ART at the time of starting. The patients needs to be informed of these. He also needs to know that there may be times when at the time of starting ART, there may be fever due to the bouncing back of the immune system. At such times, the patient may be under a lot of stress and hence requires a lot of re-assurance. Tests to be done prior to starting treatment: * Ideally, a viral load needs to be done prior to starting anti-retro-viral treatment. However, due to the cost factors involved, this is usually not done in India. 1. CD 4 count: a count less than <350 is an indicator for starting treatment. 2. Complete blood picture : Check for nutritional anaemia, bone marrow depression, High ESR, etc. 3. LFT: Any abnormalities in LFT needs to be noted. 4. Serum urea & creatinine. Any abnormalities in the test results need to be taken account of and corrected prior to starting treatment. The dosages of the Drugs available in India are: Drug Adult dose Paediatric Dose Adverse effects a) Nucleoside analogues: AZT 300mg bd 180mg/sqm tid Bone marrow depression leading to Anaemia. . nutropenia, myopathy Lamivudine 150 mg bd 4mg/kg bd Pancreatitis, peripheral Neuropathy, nutropenia Abnormal LFT Non-nucleoside reverse transcriptase inhibitors: Nevirapine 200 mg bd 120mg/sqm/day* 2 wks Syn Followed by 400mg/sqm/day Abnormal LFT c) Protease Inhibitors: Indinavir 800mg tid 500mg/sqm/day Renal stones, In 3 divided doses Abnormal LFT Anaemia, abnormal Lipid & glucose metabolism Sequenavir 1800mg/day 100mg/kg/day Increase bleeding In 3 divided doses in 3 divided doses tendencies in Hemophiliacs, Abnormal lipid & Abnormal lipid & Glucose metabolisim 2 reverse transcriptase inhibitors with a protease inhibitor is the ideal drug combination. Otherwise, a combination of 2 nucleoside reverse transcriptase inhibitors and 1 non-nucleoside reverse transcriptase inhibitor can be given. At FF, however, we give a combination of 2 reverse transcriptase inhibitors. We have found that a two drug regimen is effective for atleast 2 years in the person. Not only that, but the drug toxicities are also reduced. As the person comes off OI management, he is able to save more and if two drug regimen begins to fail, then he can shift to a three drug regimen. Advice to be given to a patient starting ART: Nutrition: The person needs to be adviced regarding good nutrition. The importance of nutrition on health needs to be reiterated. Infact, certain drugs like didanosine etc. have better absorption when taken after taking after a gastric stimulant such as a chocolate drink or an orange juice. It is important to take 4 square meals a day. The emphasis of quality food, boiling water before drinking, etc. need to be made. At Ff, we usually make it a point to give the person a list of health foods that will do him/her good. In addition, we also do advice on meal timings, and reduction of highly spicy or oily food. Blood Tests in order to monitor persons on ART: Initially every 15 days Hb% and SGOT, SGPT needs to be checked. Once the person's condition stabilizes, the tests need to be done every month initially. Then, we need to do the Hb% regularly. In children, the initial monitoring with the tests need to be done every week. Any drop in the Hb%, or elevation of hepatic enzymes needs to be paid attention to and taken care of. We also need to note that in India, nutritional anaemia is quite common an hence, we sometimes start ART in people with Hb% of 9g% also. We put the person simultaneously on oral haematinics. * CD4 counts need to be repeated every 3 months. This is only so that the doctor has an idea of the immune status of the patient. Incase the Hb drops to below 9g % or the person develops jaundice, then the anti-retro-viral treatment needs to be stopped. In case of a drop in Hb, then a TC DC needs to be done inorder to check for bone marrow depression. In such cases, the drugs will need to be stopped for some time till the side effects are corrected and then the combination of drugs changed. In order to do this, the doctor needs to be well aware of the various drugs and the side effects of the same. At Freedom Foundation, we have seen the Hb drop to 5g% within 10 days of starting treatment. At such times, we stop treatment completely and give the person blood transfusions till the Hb% develops. Hence, we make it our responsibility to advice patients to do regular blood check ups. This helps us see the progress of the patient and his compliance to the medication. Clinical follow ups: Any person on ART needs to take complete responsibility for his health. Regular follow up visits to the doctor is very important. · In some cases, Nevirapine causes a lot of side effects. In order to avoid this, we can advice the person to start with a lead in dose of 200mg od for 2 weeks and then take the full dose of 200mg bd. · Hydroxyurea given along with Stavudine or Didanosine, increases the efficacy of these drugs. · Didanosine and Stavudine are not given together. How do we know that the drugs are failing? This is why we do the CD4 counts atleast once in three months. A drop in the CD4 count despite the medication is an indicator that the drugs are not working. Where ever possible, a viral load is beneficial. When the viral load starts increasing despite the drugs, it is an indicator that the virus has developed resistance to the drugs. In such cases, we need to change the drugs to a more effective combination. · Don't add a new drug to a failing regime. · Once resistance develops, start a new combination all together. When can we stop prophylaxis for OI ? As already mentioned, all HIV +ve people with low CD4 counts need prophylaxis with Co-trimoxazole. However, when the person is on ART and the CD4 counts have gone well above 800 cells/cumm, then the physician can think of stopping ART. Prevention of Mother to Child Transmission: The risk of transmission from mother to child during pregnancy, delivery and lactation is about 40%. With interventions such as forceps, the risk of transmission increases even further. Any HIV+ve couple that opts to have a child, needs to be counseled. They need to be told about the availability of PMTCT. The counselor needs to explain to the couple the benefits of a cesarean section to reduce HIV transmission from mother to child. The need to abstain from nursing the child, to see to it that the mother goes in for PMTCT. The AZT is started in the 38th week of pregnancy. 200mg tid till the onset of labour pains. Then 3 capsules of 300mg to be given every 3 hours till the baby is delivered. The neo-nate has to be given AZT syrup 7 hours after birth. The dose is 6mg/kg. This is continued for 6-8wks. The other drug that is proven and also convenient is Nevirapine 200mg single dose at the onset of delivery. The neo-natal dose is 2mg/kg single dose. Breast feeding is completely prohibited incase mother and child opt for prophylaxis. The child needs to be artificial feeds. Also, the mode of delivery needs to be discussed. A cesarean is preferred. If they can't afford it, then during normal delivery other interventions like forceps, etc. need to be refrained from. Post exposure prophylaxis ( PEP ) : The possibility of injury via needle stick is only about 0.3%. PEP involves 3 steps: a. Reporting b. Assessment of the risk of transmission c. Prophylactic treatment where required a. Any person who sustains an injury such as needle stick (used on an HIV +ve person), injury from scissors or blades, needs to immediately report it to the person incharge or the doctor. The area needs to be cleaned first with soap and water and allow it to bleed. Within 24 hours, the person who sustained the injury needs to be started on prophylactic treatment. b. Assessment of risk & prophylactic treatment: The risk of transmission varies with kind of injury involved. If the injury is through a needle, then the risk is mild to moderate. The drugs used in this case is AZT 200mg tid (in an adult) in combination with Lamivudine 150mg bd. The treatment needs to be given for 6 weeks. If the injury is very severe like that from a scalpel blade which was used on infected tissue, then the person requires a three drug regimen is used, of 2 NRTIs and a Protease inhibitor. The protease inhibotor generally used is Indinavir 800mg tid is used. The treatment is given for 6 weeks. A PCR is adviced at the end of 3 weeks. Any person working with HIV +ve people is already working in a stressful environment. An injury of this sort only adds to the stress. Therefore, the person requires ample counseling and support from the rest of the staff. Medical ethics in dealing with PLWHAs: As doctors, we are taught to be non-judgemental and fair while rendering service to people. However, as human beings, the fear of the unknown always plagues us. This is why we need to be aware and educated about HIV & AIDS. It does exist in society and we will keep seeing an increasing number of HIV +ve people. As medical care givers, if we take all the required precautions, we are in no danger of getting infected by the virus. Medical Rights: * As doctors, we need to remember the right of a person to receive pre-test counseling prior to testing for HIV. * We also need to ensure the patients confidentiality regarding the result. · The result can be disclosed to a third person only after obtaining consent from the individual. * There is no need for a special HIV ward in any hospital. · All HIV +ve people have the right to undergo surgery or dental procedures if they so require. · No patient needs to be discharged from a hospital because he is HIV+ve. As doctors, we need to remember that HIV +ve people are more vulnerable to various illnesses and do require our care and support. As care givers, we are not at risk of getting infected with HIV if we take adequate precautions while doing invasive procedures. The right to a good quality of life is the right of any person.
